Golf is a favorite among golfers of all kinds – golfers of very different genders and ages, and/or technical level. Golf is unique in the sporting world, because golfers in such different groups can play together in golf tournaments, even compete with each other (such as obstacle scoring, different tees, team styles, etc.) and still enjoy golf. Friendship or competition. These factors, combined with the increased accessibility of golf programs on television (eg, golf tournaments, golf news, golf history, and/or other golf programs) and the rise of known golf stars, have at least partially contributed to recent years. The popularity of golf in the United States and the world has increased.

Golfers of all skill levels seek ways to improve their performance, reduce golf scores and reach the next level of performance. Manufacturers of all types of golf equipment have responded to these needs, and in recent years, operators have witnessed dramatic changes and improvements in golf equipment. For example, a wide variety of golf ball models can now be utilized to tailor a ball to a specific swing speed and/or other player characteristics or performance, for example, to make some ball designs fly farther and/or more straight; Some balls are designed to provide higher or flatter trajectories; some balls are designed to be more rotatable, controlled and/or sensation (especially near the green); some balls are designed to be faster or slower ;and many more. A number of swinging and/or technical aids are also available on the market in the hope of helping to reduce their golf scores.

As the only tool for golfing while playing, golf clubs are also the subject of many technological research and developments in recent years. For example, in recent years, the design of the putter, the design of the golf club head, the handle, and the grip have seen dramatic changes and improvements in the market. In addition, other techniques have advanced the various components and/or characteristics of the golf club and the characteristics of the golf ball with the characteristics or characteristics of the particular user (eg, golf club technology, ball launch angle measurement techniques, Ball rotation rate, etc.) is a better match.

In view of recent advances, a wide variety of golf club assemblies are available for golfers. For example, the club head can be produced in a variety of different models by a wide variety of manufacturers. Furthermore, individual club head models may include a variety of variations, such as changes in loft, lie, offset, counterweight characteristics, etc. (eg, left crank club head, right crank club head) Department, neutral weight club head, etc.). In addition, the club head can be, for example, from a different manufacturer; have different stiffness, bullet points, foldback points, or other inflection characteristics, etc.; various handle combinations made of different materials. Between the shank and the available changes in the club head, there are actually hundreds of different club head/handle combinations available for golfers.

Club analysts and golf professional golfers can help golfers with a combination of golf club head/handle for their swinging characteristics and needs. However, conventionally, golf club heads have been permanently mounted to the handle using a bonding agent or adhesive. Therefore, in order for a golfer to test a variety of different head/handle combinations, a golf analyst or professional golfer is required to carry a wide selection of permanently installed golf club head/handle combinations (this is a considerable amount) Storage space and inventory costs), or golf analysts or professional golfers need to build new clubs for consumers as this process continues (this takes a lot of time and inventory costs). Disadvantages associated with such traditional options contribute to limiting the choices available to the golfer during the poleing period, and/or significantly increasing the cost and time of a period.

2. Example handle joint

2 is a cross-sectional perspective view of an example of a handle joint 202 in accordance with an embodiment of the present invention. The handle joint 202 can be made of one or more suitable materials as described above and can comprise materials that are different than the materials contained in other portions of the golf club. For example, the handle joint 202 can include or include a rubber or other compressible material that can increase surface tension and/or reduce the handle joint 202, the handle member 106, and/or the head joint (302, below) Description) The movement between. In other embodiments, rubber and/or other materials may be used to increase shock absorption and/or reduce noise during shots. In still other embodiments, the handle joint 202 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material.

As shown in FIG. 2, the handle joint 202 has a first end 204 and a second end 206, wherein the first end 204 is along the same axis 208 as the second end 206. The handle joint 202 further includes a bore 210 along a second axis 212 that is configured to attach to a handle member 106 on the second axis 212. Accordingly, the cylindrical outer portion of the shank joint 202 extends from the first end 204 to the second end 206 in an axial direction (along the axis 208), and the cylindrical perforation 210 for the shank member 106 is disposed Different axial directions (axis 212) extend. It will be readily apparent to those skilled in the art from reviewing this disclosure that the two axes 208, 212 of the handle joint 202 can be implemented using a variety of different structural elements and/or combinations of methods. The angle difference between the first axis 208 and the second axis 212 can be any angle without departing from the invention, such as at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5 degrees, at least 4 Degree, or even at least 8 degrees.

In the embodiment illustrated in Figure 2, the perforations 210 have a circular cross-sectional shape, such as a circular handle that can accommodate a conventional shape. However, if desired, the cross-sectional shape of the perforations 210 can be a polygon having any number of sides, such as 12 or fewer sides, 10 or fewer sides, 8 or fewer sides, 6 Or fewer sides, or even 4 or fewer sides. The cross-sectional shape of the perforation 210 can be configured to have a size and shape suitable to inhibit rotation of the handle member 106 relative to the handle joint 202. This may be due to the fact that the perforations 210 of the shank joint have the same general polygonal shape as the shank member 106. In still other embodiments, the perforation 210 only partially engages or mates with the handle member 106, however this fit also prevents the handle joint 202 from rotating within the handle member 106. In certain more specific exemplary configurations in accordance with the present invention, a portion of the handle member 106 will have a square or rectangular cross-section and the perforations 210 of the handle joint 202 will include a polygonal opening (eg, having 4, 6, 8 , 12 or 16 sides) to receive the handle member 106. Alternatively, if desired, the handle joint 202 can be permanently engaged with the handle member 106, such as with a bonding agent or adhesive, using a fusion technique such as welding, brazing, or soldering, particularly for the perforation 210. An exemplary structure having a circular cross section with the handle member 106.

In some embodiments, at least one of the perforations 210 and/or the handle member 106 can have a different number of "sides" or protrusions from the other, however, the cross-sectional shape of the various different configurations can still The handle member 106 is fastened into the perforation 210 of the handle joint without the handle member 106 being free to rotate in the perforation 210. In one embodiment, the number of "sides" of one of the perforations 210 or the handle member 106 is a multiple of the number of sides of the other. Other such rotation suppression structures and configurations may also be used without departing from the invention. For example, one or both of the handle joint 202 and/or the handle member 106 can comprise a mechanical structure, such as a spring-loaded pin body or other extension structure that extends into the opening, groove or ridge (eg , similar to the hydraulic pipe attached to the hydraulic supply connection element). The jaw mechanism and other physical (and optionally static) fixed structures that fit within the opening, recess or ridge can also be used as a releasable rotation inhibiting connection without departing from the invention.

Briefly seen in Figure 4 (which will be discussed in detail below), the handle joint 202 is configured to be fixedly attached to the handle member 106. The illustrated handle joint 202 can be hollow and sized to receive a free end of a golf club shaft, such as the handle member 106. In still other embodiments, the illustrated handle joint 202 is sized to be received within a hollow portion of a free end of a golf club shaft, such as the handle member 106. Those skilled in the art will readily appreciate that the handle joint 202 need not necessarily be hollow and can be attached to a golf club in any suitable manner and mechanism, such as by, for example, by a bonding agent or adhesive; by welding , brazing or soldering or other fusion techniques; by mechanical connectors; by friction fit, etc. In some embodiments, the attachment of the handle joint 202 to a handle member 106 can be releasable to allow the handle to be easily and quickly changed. In other embodiments, the handle joint 202 can be integrally formed or permanently secured to the handle member 106. Further, as shown in Figures 2 and 4, the outer surface of the shank joint 202 may have an equal polygonal cross-sectional shape. For example, the cross-sectional shape can have 16 or fewer sides, 12 or fewer sides, 10 or fewer sides, 8 or fewer sides, 6 or fewer sides , or even 4 or fewer sides of the polygon. In other embodiments, the outer surface of the handle joint may have a circular cross-sectional shape. The cross-sectional shape of the outer surface of the shank joint is configured to have a size and shape adapted to fit within the head joint (described below) and to inhibit rotation of the shank joint 202 relative to the head joint 302.

In other embodiments, the outer side of the handle joint 202, the handle member 106, and/or the head joint (discussed below) may be tapered in the axial direction such that the diameter of the member is axial. The direction increases or decreases. This feature can help the handle joint 202 to be easily fitted into and out of the head joint and/or to avoid the need to maintain extremely tight tolerances in the manufacturing process.

3. Example head joint

The exemplary connection system 104 can further include a head joint 302. As seen in FIG. 3, the head joint 302 has a first end 304 and a second end 306. As seen, the first end 304 is along the same axis as the second end 306 (not shown). The head joint 302 further includes a bore 310 along a second axis 312 configured to receive the handle joint 202 on the second axis 312 (after the handle joint 202 is received by the handle member 106) ). Therefore, the outer portion of the head joint 302 can extend from the first end 304 in an axial direction to the second end 306, and the through hole 310 of the handle joint 202 is disposed in a different axial direction ( The axis 312) extends. Those skilled in the art will readily appreciate that reviewing this disclosure can have a variety of different structural elements and/or combinations of methods for implementing the two-axis head joint 302 without departing from the scope of the present invention. The angular difference between the first axis (not shown) and the second axis 312 can be any angle without departing from the invention, such as at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5. Degree, at least 4 degrees, or even at least 8 degrees.

As seen in Figures 3 and 4, the perforations 310 of the head joint 302 have an equal polygonal cross-sectional shape. For example, the cross-sectional shape can have 12 or fewer sides, 10 or fewer sides, 8 or fewer sides, 6 or fewer sides, or even 4 or fewer The polygon on the side. The cross-sectional shape of the perforation 310 is configured to have a size and shape suitable to inhibit rotation of the shank joint 202 relative to the head joint 302. As noted above, this may be due to the fact that the perforations 310 of the head joint have the same general polygonal shape as the outer surface of the shank joint 202. In still other embodiments, the perforation 310 only partially engages or mates with the handle joint 202, however this fit also prevents the handle joint 202 from rotating in the head joint 302. In certain more specific exemplary configurations in accordance with the present invention, the handle joint 202 will have a square or rectangular cross-section and the perforations 310 of the head joint 302 will comprise a polygonal opening (eg, having 4, 8, 12 or 16 The sides are configured to receive the handle joint 202.

Thus, at least one of the outer surface of the perforation 310 and/or the shank joint 202 can have a different number of "sides" or protrusions from the other, however, the cross-sectional shapes of the various different configurations can still The handle joint 202 is fixedly inserted into the through hole 310 of the head joint without allowing the handle joint 202 to freely rotate in the through hole 310. In one embodiment, the number of "sides" of one of the perforations 310 or the handle joints 202 is a multiple of the number of sides of the other. In still other embodiments, the perforations 310 of the head joint 302 can have a circular cross-sectional shape, i.e., shaped to receive one of the handle joints 202 having an outer surface and a circular cross-sectional shape. Other such rotation suppression structures and configurations may also be used without departing from the invention. For example, one or both of the head joint 302 or the handle joint 202 can comprise a mechanical structure, such as a spring-loaded pin body or other extended structure that extends into the opening, groove or ridge (eg , similar to the hydraulic pipe attached to the hydraulic supply connection element). The jaw mechanism and other physical (and random static) securing structures that fit within the opening, recess or ridge can also be used as a releasable rotation inhibiting connection without departing from the invention.

As shown in FIG. 3, the handle joint 202 can be configured to fully fit within the head joint 302. In other embodiments, the shank joint 202 will extend less than 50% of the total axial length of the head joint 302, and may also extend less than 35%, 25% of the total axial length of the head joint 302, or even 15%. This feature can help keep the overall connection system relatively short, tight, and lightweight. Alternatively, if desired, a portion of the handle joint 202 can remain outside of the head joint 302 (and optionally, the handle joint 202 can be disposed outside the head joint to be disposed with the handle joint 202 The shape of the head joint is different). As discussed below with respect to FIG. 6, the configuration of the handle joint 202 and its configuration relative to the club head body can be utilized to adjust various positions of the ball striking face of the golf club head 102 and/or Or angle (such as lying angle, loft, face angle, etc.).

In other embodiments, the illustrated head joint 302 can be sized to be received in a hollow portion, such as the perforation 210 of the handle joint 202, as described above in relation to certain embodiments, wherein the handle member 106 It is fitted in the handle joint 202. Further, in other embodiments, the head joint 302 can be integrally formed or permanently fixed to a club head 402, such as by a neck 404.

As discussed above, the shank joint 202 and the head joint 302 need not be the same shape, but only need to cooperate with each other on one of several rotational orientations that are related to each other and/or associated with the club head 402. For example, as described below.

The illustrated handle joint 202 of FIGS. 5A-5D includes indicia 502 and the illustrated head joint 302 includes indicia 504. A symbol 502 on the handle joint 202 indicates the rotational position of the handle joint 202 relative to the head joint 302 and the club head 402. A symbol 504 on the head joint 302 indicates the rotational position of the head joint 302 associated with the club head 402 and the handle joint 202. An advantage of the markers 502, 504 is that the user can more accurately record the club head/handle orientation and/or can reliably return to one after the one or more members are rotated relative to the handle member 106. Previous location. Since both the illustrated handle joint 202 and the head joint 302 are generally octagonal in this exemplary configuration, they can be articulated in a releasable manner with a fixed orientation of 64. Accordingly, those discussed below will be directed to the position of the head joint 202 and the handle joint 302 when in a rotational position range from 1 to 8, where the position 1 is when the marks 502, 504 are at Fig. 5A. The middle is at 12 o'clock and the subsequent positions are numbered consecutively in clockwise order. In still further embodiments, the club head 106 can be marked with a mark if desired.

Depending on how the head joint 202 and/or the handle joint 302 are positioned relative to the "face" of the club head 102, the striking characteristics of the club can be varied. With this feature, with the releasable connection system 104, the club analyst (or others) can freely and easily adjust various angles and/or positions of the handle member 106 relative to the club head 102. (eg, various reclining angles, loft angles, and face angle combinations) while still using the same handle 106 and/or head 102, which helps the user to more easily determine the best club head/ The handle is combined and configured to suit its needs. Referring to Figure 5A, the symbol 502 indicates that the handle joint 202 is in position 1, and the symbol 504 indicates that the head joint 302 is also in position 1. As seen in FIG. 5B, the handle joint 202 (and the handle 106) has been rotated to position 2 while the head joint 302 remains at position 1.

Repositioning of the handle joint 202 relative to the head joint 302 can have the advantage that the club head/handle orientation can be adjusted by known factors. For example, information relating to the off-axis angle of the perforations 210, 310 can be coupled to the handle joint 202 and the head joint 302. The information may be provided to the connectors 202, 302, which may be printed, engraved or otherwise marked on the connectors 202, 302, provided separately, or otherwise provided.

Figure 6 provides a table 600 showing illustrative information regarding the adjustment of the handle joint 202 relative to the club head 402 (with the head joint 302 remaining at a fixed position relative to the club head 402). . This information is related to the embodiment shown in Fig. 3, where both the shank joint 202 and the head joint 302 are generally octagonal. In this particular embodiment, the perforation 210 of the handle joint is offset from the center by about 2 degrees, and the perforation 310 of the head joint is offset from the center by about 1 degree, although the angle of deviation can range from 0.25 to 4 degrees. In some instances, the angle is in the range of 0.5 to 2 degrees. Table 600 shows one-eighth (or about 45 degrees) of the full circumference of the handle joint 202 in a clockwise direction relative to the head joint 302, the face angle (column 604), the lying angle (column 606), And the change in loft (column 608). As can be seen in the first row of column 602, the handle joint 202 is set to position 1 (so as shown in Figure 5A, the symbol 502 is at the 12 o'clock position). When the handle joint 202 and the head joint 302 are set at position 1 (as shown in FIG. 5A), the face angle and the loft angle do not change, however, the lying angle is at +3 degrees. (See line 610 in Figure 6).

However, for example, when the handle joint 202 is set at position 2 (or rotated about 45 degrees in a clockwise direction) and the head joint 302 remains at position 1, as shown in FIG. 5B, the face angle is adjusted. At -0.7 degrees, the lying angle is changed to +2.4 degrees and the loft angle is increased by 1.2 degrees (see line 612 of Figure 6). As shown elsewhere in Table 600, the face angle, lying angle, and loft angle can be adjusted to a known amount by repositioning the handle joint 202 relative to the head joint 302. Further, as shown in Figures 5C-5D, the head joint 302 can also be adjusted separately or together with the repositioning of the handle joint.

In a further embodiment, the "hand side" of the handle joint 202 and/or the head joint 302 can include a projection on the periphery. For example, the members may have a generally circular shape, however, the protrusions may also be placed or disposed on the periphery of the structure to produce substantially the same effect as the "sides". Of course, any structure, shape, extension, etc., which mimic the traditional side features, are within the scope of the invention and are included in the term "side" as used herein. In some more specific exemplary configurations in accordance with the present invention, the rotation suppression structure of the inner chamber has a square or rectangular cross section. In other embodiments, the inner chamber may be in an irregular shape such that the "sides" are not uniform. This can be useful, for example, when it is desired that a handle is not inserted in a manner that provides good club characteristics. In one embodiment, there are several possible configurations for placing the handle joint in the golf club head, wherein at least one configuration provides club characteristics that are different from the other configuration.

E. Other features and examples of the invention

The aspects of the invention described herein may be further defined by the following other example structures. The following example structure is explained with reference to the above-described exemplary club structure and Fig. 1 . Exemplary elements of these configurations (discussed separately below) are depicted together in FIG. 9, which is an exploded perspective view of the golf club 900 (discussed below).

Example handle joint

Figure 7 is a cross-sectional perspective view of an example of a handle joint 702 in accordance with this example of the present invention. The illustrated handle joint 702 is similar to the illustrated handle joint 202 described above, however, the outer surface of the handle joint 702 can be defined, in whole or in part, by a key 716 extending along a vertical axis 708 (which is also shown in Figure 9). ). The handle joint 702 can be made of one or more suitable materials as described above, and can comprise a different material than the material contained in other sections of the golf club. For example, the handle joint 702 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material.

The shank joint 702 is generally cylindrical and has a first end 704 and a second end 708 along the same axis 708. The handle joint 702 further includes a bore 710 along a second axis 712 that is configured to attach to one of the handle members 106 on the second axis 712. The outer portion of the shank joint 702 extends from the first end 704 to the second end 706 in an axial direction (along the axis 708), and the cylindrical bore 710 that receives the shank member 106 can have a different axial direction. The direction (axis 712) extends. According to the exemplary configuration shown in Figures 7-9, the exterior of the handle joint 702 can be further defined by a flange 714 that is adapted to be mated and mated by an opening 816 of the head joint 802 (Fig. 8 Shown). Alternatively, the bottom surface of the flange 714 can simply rest against the top surface of the head joint 802. Those skilled in the art will appreciate that the two axes 708 and 712 used to perform the handle joint 702 can use a variety of different structural elements and/or combinations of methods. Similar to the exemplary structure 202 described above, the angular difference between the first axis 708 and the second axis 712 can be any angle without departing from the invention, for example, at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees. At least 2.5 degrees, at least 4 degrees, or even at least 8 degrees.

In the structure shown in Fig. 7, the perforation 710 has a circular cross-sectional shape to, for example, accommodate a conventionally shaped circular shank. However, if desired, the cross-section of the perforation 710 can be configured to have a size and shape that is adapted to inhibit rotation of the handle member 106 relative to the handle joint 702. For example, the shape of the perforation itself may be defined by vertical key teeth that are shaped to partially form the outer teeth of the key teeth and engage a handle member. The handle joint 702 can be configured in a variety of manners relative to the handle joint 202 such that the perforations 710 engage or mate with the handle member 106 and such fit can prevent the handle joint 702 from being in the handle member 106 Rotate. In other constructions, the handle joint 702 can be permanently engaged with the handle member 106 (eg, by a bonding agent or adhesive; by welding, brazing, soldering, or other fusion techniques; by mechanical connectors) By means of a friction fit or the like, in particular, the perforation 710 and the handle member 106 have an exemplary structure having a circular cross section. Those skilled in the art will readily appreciate that the combination of the handle joint 702 and the handle member 106 can be used in a number of different ways.

Other rotation suppression structures and configurations can also be used without departing from the invention. For example, one or both of the handle joint 702 and/or the handle member 106 can comprise a mechanical structure, such as a spring loaded pin body or other extension structure that extends into the opening, groove or ridge (eg, similar) The hydraulic pipe is attached to the oil pressure supply connection element). The jaw mechanism and other physical (and optionally static) fixed structures that fit within the opening, recess or ridge can also be used as a releasable rotation inhibiting connection without departing from the invention.

Referring briefly to Figure 9, which will be described in more detail below, the handle joint 702 is configured to be fixedly attached to the handle member 106. The illustrated handle joint 702 can be hollow and can have a free end that incorporates a golf club shaft, such as the size of the handle member 106. Thus, in some exemplary configurations, the connection of the handle joint 702 to a handle member 106 can be releasable to allow for easy and rapid transition of the handle. In other constructions, the handle member 702 can be integrally formed with the handle member 106 or permanently fixed.

Further as shown in Figures 7 and 9, the outer surface of the handle member 702 at the second end 706 has a cross-sectional shape that can be defined along the teeth of the axis 708 of the handle joint. The fingers can create a ridge along the surface that is sized to fit and engage one of the key teeth of the other surface, such as the interior of the head joint 802 shown in FIG. The dents may be formed by ridges on the surface of the material comprising the shank joint 702 and may be processed according to a variety of different known techniques, such as by extrusion, molding, casting, or any other person skilled in the art. Known mechanical techniques. According to the structure shown in Fig. 7, the keys can extend to the flange 714. Also, in the illustrated construction, the flange 714 is adapted to seat against the top 816 of the head joint 802 (head joint 802 of Figure 8 will be described in more detail below). Accordingly, the cross-sectional shape of the outer surface of the shank joint 702 is configured to fit within the head joint 802 (described below) and to inhibit rotation of the shank joint 702 relative to the head joint 802. shape.

In accordance with the teachings of the invention described herein, the fingers 716, 820, and 906 (which will be further described below) may be formed by staggered ridges and grooves that are triangular, circular, square, or generally trapezoidal. . The fingers 716 (or polygonal cross-sectional areas) may extend along any length of the outer surface of the handle joint 702 (or the head joint 802 or the perforation of the neck region 904) without departing from the present invention. For example, the keys 716 can extend 10-100% of the total length of the outer surface of the handle joint 702, and in some exemplary configurations, the keys 716 can extend a total length of 15- 80%, or even 20-60% of the total length. The portion including the outer surface of the key 716 may also be located at any desired position along the length without departing from the invention, such as extending upwardly from the second end 706, extending from the flange region 714 to the second End 706 and so on. The key teeth 716 may also extend only a portion of the outer surface of the handle joint 702. For example, the outer surface of the handle joint 702 can be defined by strips that are equally spaced around the outer surface of the key teeth 716 that extend along the length or along the axis 708 of the handle joint 702. .

In some exemplary configurations, the outer surface of the handle joint 702, the handle member 106, and/or the head joint 802 may have a tapered shape in the axial direction at a position other than a circular cross-section. The diameter of the member is slightly reduced from the first end to the second end. This feature can help the handle joint 702 to be easily fitted to and slid out of the head joint 802, and/or to avoid the need to maintain extremely tight tolerances in the manufacturing process.

2. Example head joint

According to other examples of the invention, the illustrative connector of FIG. 9 can further include a header connector 802. The head joint 802 can be made of one or more suitable materials described above and can include a different material than the material of the other segments that comprise the golf club. For example, the head joint 802 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material. Referring to FIG. 8, the head connector 802 has a first end 804 and a second end 806. As can be seen, the first end 804 is along the same axis as the second end 806 (not shown). The head joint 802 further includes a bore 810 along a second axis 812 that is configured to receive the handle joint 702 on the second axis 812 (the handle joint 702 in turn receives the handle member 106 ). Thus, the outer portion of the head joint 802 can extend from the first end 804 in an axial direction to the second end 806, and the perforations 810 of the handle joint 702 are received in different axial directions (axis 812 )extend. It will be readily apparent to those skilled in the art from reviewing this disclosure that the two axes of the head joint 802 can be implemented using a variety of different structural elements and/or combinations of methods without departing from the scope of the invention. The angular difference between the first axis (not shown) and the second axis 812 can be any angle without departing from the invention, such as at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5 degrees. At least 4 degrees, or even at least 8 degrees.

The cross-sectional shape of the perforation 810 of the head joint 802 can be defined by key teeth 820 extending along a vertical axis 812 that is shaped to engage and engage the outer teeth 716 of the handle joint 702. A fixed position. The dents may be formed by ridges on the surface of the material comprising the head joint 802 and may be processed according to a variety of different known techniques, such as by extrusion, molding, casting, or any other person skilled in the art. Known mechanical techniques. Thus, the cross-sectional shape of the perforation 810 can be configured to have a size and shape suitable to inhibit rotation of the handle joint 702 relative to the head joint 802. However, in other exemplary configurations, the perforation 810 is only partially engaged or mated with the handle joint 702, and the mating or other engagement means also prevents the handle joint 702 from rotating in the head joint 802. In the particular exemplary configuration shown in FIGS. 8 and 9, the first end 804 of the head joint 802 can be defined by a recess 816 that is shaped when the handle joint 702 fits within the bore 810 of the head joint 802. The flange 714 of the shank joint 702 can be received.

Other rotation suppression structures and configurations can also be used without departing from the invention. For example, one or both of the head joint 802 or the handle joint 702 can comprise a mechanical structure, such as a spring loaded pin body or other extension structure that extends into the opening, groove or ridge (eg, similar to a hydraulic tube) Attached to the hydraulic supply connection element). The jaw mechanism and other physical (and optionally static) fixed structures that fit within the opening, recess or ridge can also be used as a releasable rotation inhibiting connection without departing from the invention.

As shown in FIG. 8, the handle joint 702 can be configured to only partially fit into the head joint 802. In other constructions, the handle joint 702 can extend more or less than the axial length of the head joint 802. Further, as discussed below in relation to Figures 10A, 10B, 10C and 10D, the configuration of the handle joint 702 and its configuration relative to the club head can be utilized to adjust the ball striking face of the golf club head 102. Various positions and/or angles (eg, lying angle, loft, face angle, etc.).

In other exemplary configurations in accordance with the present invention, the head joint 802 can be integrally formed with a club head 902 or permanently fixed, such as being received in the neck region 902 or integrally formed as a neck region 904. portion. In such configurations, the outer surface of the head joint 802 may be absent (if the club head structure has an outer neck, the neck hole may extend from the outer surface of the neck in an "off-axis" manner).

3. Assembly method of alternative structure according to the present invention

Figure 9 depicts an exploded perspective view of a golf club 900 in accordance with one of the examples of the present invention as depicted in Figures 7 and 8 and described above. The exploded view of the golf club 900 also emphasizes one of several methods that can be used to construct a golf club in accordance with certain aspects of the present invention. According to an exemplary method, the handle member 106 is attached to the handle joint 702 having a first end 704 and a second end 706 along a first axis 708, wherein the handle member 106 is interposed Aperture 710 extends along a second axis 712 (axis 712 is shown in Figure 7). The handle member 106 can be permanently affixed to the shank joint 702 (eg, by a bonding agent or adhesive, by fusion techniques such as welding, brazing, or soldering), or the components 106 and 702 can be mutually Releasably connected. The method can further include inserting the second end 706 of the handle joint 702 into the bore 810 of a head joint 802, wherein the head joint 802 includes a first end 804 along a first axis 808 and a The second end 806, and wherein the perforation 810 has a cross-sectional shape defined by the key teeth 820, and is shaped as a key tooth 716 that can receive the second end 706 of the handle joint 702 in a plurality of different orientations. The method can further include inserting the head joint 802 into the neck region 904 of a club head 902. The neck region 904 can have an inner opening having a cross-sectional shape defined by key teeth 906 that are shaped to receive the second end 806 of the head joint 802 in a plurality of different orientations. Key teeth 818. Depending on the configuration selected, the insertion of the head joint 802 into the neck region 904 can be selected from a number of different orientations, for example, as discussed below with respect to Figures 10A-10D. Accordingly, other methods in accordance with the present invention can include removing the handle joint 702 from the head joint 802 and the second end 706 of the handle joint 702 in a different orientation (eg, at a different rotation) Positioned again in the bore 810 of the head joint 802; and/or remove the head joint 802 from the neck region 904 of the club head 902, and the head joint 802 is Different orientations (e.g., at a different rotational position) are reinserted into the neck region 904 of the club head 902.

The illustrated neck region 904 can include an internal chamber or perforation for receiving the head joint 802. The perforations can be machined into the head during manufacture of the golf club head according to processing techniques known to those skilled in the art. In one exemplary configuration, the neck region 904 is formed by drilling or puncturing a portion of the golf club head 902. As such, at least a portion of the outer perimeter of the neck region 404 includes the same material as the golf club head 902. Further, the shape of the perforations may be defined by key teeth to engage the head joint 802 having a profile defined by the key teeth in a cohesive manner. The handle member 106 can be secured to the club head 902 (through the handle joint 702 and the head joint 802) in any desired manner, including a releasable attachment system as is known and used in the art. As can be seen in the exploded view of FIG. 9, the exterior of the neck region 904 can have threads 910. The thread 910 can be threaded with the thread 910 on the outer surface of the neck region 904 by a nut 908 that passes over the first end 704 of the shank joint to secure the entire joint assembly. As another example, a bolt can extend through an opening disposed in the club head (eg, in the bottom of the club head) that engages a threaded portion disposed in the bottom of the handle member 106, Handle joint 202, and/or head joint 302.

4. Adjust the head joint and the handle joint

Since the axis of the perforation 710 in the handle joint 702 can be offset from the axis of the outer surface of the handle joint 702, and since the axis of the perforation in the head joint 802 can be offset from the axis of its outer surface, the joints are relatively Rotation of the club head 902 will change the position of the shank member 106 relative to the ball striking face of the club head. Such deviations may be angles in the range of 0.25 to 4 degrees, and in some examples, the deviation may be an angle in the range of 0.5 to 2 degrees. 10A-10D each show a top view of a portion of a golf club in accordance with an alternative exemplary structure of the present invention, where both the handle joint 702 and the head joint 802 can be placed in different rotations relative to the club head 902. Orientation. With respect to the rotation of the structure depicted in Figures 5A-5B, where the rotation must be equal to at least one full side of the polygon, the alternative structure depicted in Figures 7-9 allows for more incremental incremental rotation. In particular, referring to FIG. 10A, the handle member 106 is securely retained in the handle joint 702. As seen in Figures 10A-10D, the shank joint 702 has an outer shape defined by the teeth extending along the axis 708 of the shank joint 702. The outer surface of the handle joint 702 is in engagement with and mated with the head joint 802 defined by the key teeth extending along the axis 812 of the head joint 802, and has a shape of an inner peripheral perforation for receiving the handle Portion 702. In FIGS. 10A-10D, the outer surface of the handle joint 702 and the perforations of the head joint 802 are similarly shaped such that the key teeth of the head joint 802 are in a plurality of different rotational orientations with the handle joint 702. The key teeth are placed and connected to each other, but in this way, rotation and movement can also be suppressed.

The illustrated handle joint 702 of Figures 10A-10D can include the indicia 1002 and the illustrated head joint 802 can include the indicia 1004. A symbol 1002 on the handle joint 702 indicates the rotational position of the handle joint 702 relative to the head joint 802 and the club head 902. A symbol 1004 on the head joint 802 indicates the rotational position of the head joint 802 associated with the club head 902 and the handle joint 702. An advantage of the markers 1002, 1004 is that the user can more accurately record the club head/handle orientation and/or can reliably return it after one or more components are rotated relative to the handle member 106. Go to a previous location. Since both the illustrated handle joint 702 and the head joint 802 are shaped as defined by the key teeth 716, 818 and 820, they can be engaged and fastened in a releasable manner in a plurality of rotational orientations. Accordingly, discussed below is related to the position of the head joint 702 and the handle joint 802 when in the incremental rotational position. Position 1 means that when the symbols 1002, 1004 are at the 12 o'clock position in Figure 10A, and the subsequent positions are illustrated as incremental rotations in a clockwise sequence. In still further embodiments, the club head 902 may also be marked with a mark if desired.

Depending on how the handle joint 702 and/or the head joint 802 are positioned relative to the "face" of the club head 102, the strike characteristics of the club can be altered. This feature, along with the releasable connection system 104, allows the club analyst (or others) to freely and easily adjust various angles and/or positions of the handle member 106 relative to the club head 102 ( For example, various reclining angles, loft angles, and face angle combinations) while still using the same handle 106 and/or head 102, this helps the user to more easily determine the best club head/handle Departments are combined and configured to suit their needs. Referring to Figure 10A, the symbol 1002 indicates that the handle joint 702 is in position 1, and the symbol 1004 indicates that the head joint 802 is also in position 1. As seen in FIG. 10B, the handle joint 702 (and the handle 106) has been rotated slightly in a clockwise direction while the head joint 802 remains in position 1.

On the other hand, in Fig. 10C, the head joint 802 (and the club head 102) has been rotated slightly in a clockwise direction while the handle joint 702 remains at position 1. In FIG. 10D, both the handle joint 702 and the head joint 802 have been rotated slightly in a clockwise direction to effectively rotate the handle 106 and the club head 102 to each other.

Repositioning of the handle joint 702 relative to the head joint 802 as described may have the advantage that the club head/handle orientation can be adjusted by known factors. For example, information relating to the off-axis angle of the perforations 710, 810 can be coupled to the handle joint 702 and the head joint 802. The information may be provided to the connectors 702 and 802 and may be printed, engraved or otherwise marked on the connectors 702 and 802, separately or may be provided in other manners. Those skilled in the art will appreciate that the 10A-10D diagrams represent only four configurations of a plurality of rotational orientations, where the handle joint 702 and the head joint 802 can be releasably engaged and fastened.

The handle joint 1106 depicted in FIG. 11B has an outer cross-sectional shape of a regular polygon and is shaped to engage and engage with a regular polygon of the inner perforation of the head joint 1108. The further embodiments depicted in Figures 11A and 11B are only two of the many different combinations of embodiments that fall within the scope of the present invention and will be appreciated by those skilled in the art. As in a more particular embodiment, any desired polygonal cross-sectional shape can be used without departing from the invention, such as from 3 to 20 sides.

F. Other exemplary structures of the invention

The features of the invention described herein may be further defined by the following other illustrative structures. The following exemplified structure is explained with reference to the illustrated club structure as described above and in Fig. 1.

1. Example of a shank joint/head joint assembly having a bottom feed head joint

Figures 12A and 12B show an adjustable handle joint/head joint assembly in accordance with another exemplary construction of the present invention. Figure 12A is a cross-sectional perspective view showing an example of a handle joint 1202 and a head joint 1224 in accordance with an embodiment of the present invention. Figure 12B is an exploded view of the handle joint/head joint assembly depicted in Figure 12A.

The illustrated handle joint 1202 is similar to the illustrated handle joint 702, wherein the outer surface of the handle joint 1202 can extend along the longitudinal axis of the handle joint 1202 with key teeth 1204 (depicted in Figure 12B) in whole or in part. Defined. The handle joint 1202 can be made of one or more suitable materials described above and can include materials that are different than the materials included in other sections of the golf club. For example, the handle joint 1202 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material.

The shank joint 1202 is generally cylindrical and has a first end 1206 along the same axis, an intermediate portion 1208, and a second end 1210. According to the illustrated structure depicted in Figures 12A and 12B, the first end 1206, the intermediate portion 1208, and the second end 1210 can each exhibit a decreasing diameter. The first end 1206 can include a lip 1212 that can seat against a support region 1214 of the neck region 1216. The handle joint 1202 further includes a perforation 1218 configured to be attached to a handle member 106 along an offset axis 1220. The off-axis 1220 can be offset from the center journal axis 1222 by about 2 degrees, although the angle of departure can be any angle without departing from the invention, such as at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5. Degree, at least 4 degrees, or even at least 8 degrees.

In addition, the second end 1210 can include a fixed structure (for example, a screw hole 1211 in the illustrated structure), which helps to securely attach the handle joint 1202 to a club head body, as described in detail below. Description. In the illustrated structure, as shown in FIG. 12A, the through hole 1218 is not opened to the screw hole 1211, but if necessary, the screw hole 1211 can be extended to and opened to the inside according to some structures of the present invention. Chamber 1218.

According to the illustrated construction shown in Figures 12A and 12B, the perforations 1218 can have a circular cross-sectional shape, such as a circular handle that can accommodate a conventional shape. However, if desired, the cross-sectional shape of the perforation 1218 can be configured to have a size and shape that inhibits rotation of the handle member 106 relative to the handle joint 1202. For example, the shape of the perforation 1218 itself may be defined by key teeth that are shaped to engage and engage one of the shank members having a portion of the outer portion of the key. As described above, corresponding to the handle joint 202, the handle joint 1202 can be configured in a number of ways such that the perforations 1218 can engage or mate with the handle member 106, and such mating prevents the handle joint 1202 from being in the handle The member 106 rotates. In other constructions, the handle joint 1202 can be permanently engaged with the handle member 106 (eg, by a bonding agent or adhesive; by welding, brazing, soldering, or other fusion techniques; by mechanical connection) By means of a friction fit or the like, in particular an exemplary structure having a circular cross section of the perforation 1218 and the handle member 106. Those skilled in the art will readily appreciate that the combination of the handle joint 1202 and the handle member 106 can be used in a number of different ways.

Other rotation inhibiting structures and configurations that are placed in the handle joint 1202 relative to the handle 106 can also be used without departing from the invention. For example, one or both of the handle joint 1202 and/or the handle member 106 can comprise a mechanical structure, such as a spring loaded pin body or other extension structure that extends into the opening, groove or ridge (eg, similar) The hydraulic pipe is attached to the oil pressure supply connection element). The jaw mechanism and other physical (and optionally static) fixed structures that fit within the opening, recess or ridge can also be used as a releasable rotation inhibiting connection without departing from the invention. Thus, in some exemplary configurations, the attachment of the handle joint 1202 to a handle member 106 can be releasable to allow for easy and rapid transition of the handle. In other constructions, the handle joint 1202 can be integrally formed or permanently affixed to the handle member 106.

As shown in Figures 12A and 12B, the outer surface of the handle joint 1202 can have a cross-sectional shape that is fully or partially defined by the key teeth 1204 extending along the axis 1220 of the handle joint. The key teeth 1204 can form a ridge along the surface that is sized to engage and engage a key tooth of the other surface, such as the key 1232 in the interior of the head joint 1224, in a fixed position. The fingers 1204 can be formed from ridges on the surface of the material comprising the shank joint 1202 and can be processed according to a variety of different known techniques, such as by extrusion, molding, casting, or any other skill familiar to the art. Mechanical technology known. According to the illustrated construction depicted in FIG. 12B, the key teeth 1204 can extend along the second end 1210 of the handle joint 1202. Accordingly, the cross-sectional shape of the outer surface of the handle joint 1202 can be configured to fit to the neck region 1216 (shown in FIG. 12B) and the head joint 1224 (plugged into the bottom of the club head 1200, Illustrated in the following), and suppressing the size and shape of the handle joint 1202 relative to the head joint 1224.

According to the features of the invention described herein, the key teeth 1241 in the bottom of the inner chamber 1242 and the key teeth 1230 and 1232 (which will be further described below) may be formed by staggered ridges and grooves. It is triangular, circular, square or generally trapezoidal. The fingers 1204 (or polygonal cross-sectional areas) may extend along any length of the outer surface of the handle joint 1202 (or the perforation of the head joint 1224 or the neck region 1216) without departing from the present invention. For example, the keys 1204 can extend 10-100% of the total length of the outer surface of the handle joint 1202, and in some exemplary configurations, the keys can extend the total length of 15-80 %, or even 20-60% of the total length. The portion including the outer surface of the key 1204 can also be located at any desired position along the length without departing from the invention, such as extending upwardly from the second end 1210, extending from the lip region 1212 to the second End 1210 and so on. The fingers 1204 can also extend only around the outer surface portion of the handle joint 1202. For example, the outer surface of the handle joint 1202 can be defined by strips that are equally spaced around the outer surface of the key teeth 716 that extend along the length or along the axis 1220 of the handle joint 1202. . Moreover, the key regions 1204, 1241, 1230, and 1232 can be replaced with any cross-sectional shape having a regular polygon from any of the 3 to 20 sides without departing from the invention.

In some exemplary configurations, the outer surface of the handle joint 1202, the handle member 106, and/or the head joint 1224 may have a tapered shape in the axial direction at a position other than the circular cross section. The member has a diameter from the first end 1206 that traverses the intermediate portion 1208 and is slightly reduced across the second end 1210. This feature can help the handle joint 1202 to be easily fitted to and slid out of the head joint 1224, and/or to avoid the need to maintain extremely tight tolerances in the manufacturing process.

According to other embodiments of the invention depicted in Figures 12A and 12B, the illustrated connector may further include a head joint 1224. The head joint 1224 can be made of one or more suitable materials described above and can include a different material than the material of the other segments that comprise the golf club. For example, the head joint 1224 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material. Referring to Figures 12A and 12B, the illustrated head joint 1224 has a first end 1226 and a second end 1228. As can be seen, the first end 1226 is along the same axis as the second end 1228 (e.g., axis 1220 of Figure 12A). The head joint 1224 further includes a perforation 1231 along a second axis 1234 that is configured to receive the shank joint 1202 on the second axis 1234 (the shank joint 1202 sequentially receives the shank member 106) ). Thus, the outer portion of the head joint 1224 can extend from the first end 1226 in an axial direction to the second end 1228 (axis 1220), and the perforations 1231 of the shank joint 1202 can be placed in different axial directions. The direction (axis 1234) extends. It will be readily apparent to those skilled in the art from reviewing this disclosure that the two axes of the head joint 1224 can be implemented using a variety of different structural elements and/or combinations of methods without departing from the scope of the invention. The angle difference between the first axis 1220 and the second axis 1234 can be any angle without departing from the invention, such as at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5 degrees, at least 4 Degree, or even at least 8 degrees.

The through hole 1231 of the head joint 1224 can also have a cross-sectional shape defined by the key teeth 1232 extending longitudinally in the through hole 1231. The key teeth 1232 are shaped to fit and engage the outer portion of the handle joint 1202. The key teeth 1204 are in a fixed position. The fingers 1232 can be formed from ridges on the surface of the material comprising the head joint 1224 and can be processed according to a variety of different known techniques, such as by extrusion, molding, casting, or any other skill familiar to the art. Mechanical technology known. Thus, the cross-sectional shape of the perforation 1231 can be configured to have a size and shape suitable to inhibit rotation of the handle joint 1202 relative to the head joint 1224. According to the cross-sectional view of Fig. 12A, only a portion of the perforation 1231 is engaged or mated with the shank joint 1202. In other embodiments, the head joint 1224 is sized to allow the handle joint to be placed over the entire length of the head joint 1224.

In the particular exemplary configuration depicted in Figures 12A and 12B, the club head 1200 can have an inner chamber 1242 defined within the bottom of the club head 1200 that provides an opening along the axis 1220 for The head joint 1224 is placed. As seen in FIG. 12A, the head joint 1224 is adapted to be inserted into the inner chamber 1242 such that the second end 1228 of the head joint 1224 receives the neck of the club head 1200 in a rotationally inhibiting manner. The second end 1210 of the handle joint 1202 is within the region 1216 and engages therewith. The inner chamber 1242 can be defined by the mating face 1236 as shown in FIG. 12A. According to the illustrated construction shown in Fig. 12A, the head joint 1224 further includes a flange 1244 that seats against the mating face 1236. The outer surface of the head joint 1224 can also be defined by key teeth 1230 that can be configured to be received and engaged by the key teeth 1241 in the bottom of the inner chamber 1242 in a rotationally inhibited manner.

The shank joint 1202/head joint 1224 assembly can be secured to the club head with a shim 1240 and a screw 1238 as depicted. Those skilled in the art will appreciate that there are many different ways to lock the components of Figures 12A and 12B. For example, instead of the screw 1238, the head joint 1224 can be permanently secured within the inner chamber 1242 of the neck region by conventional techniques.

Other rotation suppression structures and configurations may also be used without departing from the invention. For example, one or both of the head joint 1224 or the handle joint 1202 can comprise a mechanical structure, such as a spring-loaded pin body or other extension structure that extends into the opening, groove or ridge (eg, similar) The hydraulic pipe is attached to the oil pressure supply connection element). The jaw mechanism and other physical (and optionally static) fixed structures that fit within the opening, recess or ridge can also be used as a releasable rotation inhibiting connection without departing from the invention.

As shown in FIG. 12A, the handle joint 1202 can be configured to only partially fit into the head joint 1224. In other constructions, the handle joint 1202 can extend more or less than the axial length of the head joint 1224. In a further exemplary configuration in accordance with the present invention, the head joint 1224 can be integrally formed or permanently affixed to a club head 1200, such as can be placed or integrally formed as part of the neck region 1236. In such a configuration, the outer surface of the head joint 1224 may be absent (if the club head structure has an outer neck, the neck hole may extend from the outer surface of the neck in an "off-axis" manner).

The exploded view of the shank joint 1202/head joint 1224 assembly of Fig. 12B further emphasizes one of several methods that may be used to construct a golf club in accordance with certain aspects of the present invention. According to the illustrated method, the handle member 106 is attached to the handle joint 1202, wherein the handle member 106 is inserted into one of the perforations 1218 that extend along a second axis 1220. The method can further include inserting the second end 1210 of the handle joint 1202 into a perforation 1231 of a head joint 1224, wherein the perforation 1231 has a cross-sectional shape defined by the key teeth 1232, and the shape is The key teeth 1204 of the second end 1210 of the handle joint 1202 can be received in a plurality of different orientations. The method can further include inserting the head joint 1224 into a region 1242 defined by the mating face 1236 at the bottom of a club head 1200. The bottom of the rod neck 1216 or the bottom of the inner chamber 1242 may have an inner opening, the cross-sectional shape of which is defined by the key teeth 1241, and the shape of the key teeth 1241 is such that the head can be placed in several different orientations. The key 1230 of the second end 1228 of the joint 1224. Depending on the configuration selected, the insertion of the head joint 1224 in the neck region defined on the bottom of the club head 1236 can be selected from a number of different orientations, for example, symbol 12 of 1236 as shown in Figure 12B. 8 marked. Accordingly, other methods in accordance with the present invention can include removing the handle joint 1202 from the head joint 1224 and the second end 1210 of the handle joint 1202 in a different orientation (eg, at a different rotation) Positioned again in the perforation 1231 of the head joint 1224; and/or remove the head joint 1224 from the bottom of the neck region and reinsert the head joint 1224 in a different orientation The club head 1200 is within the bottom of the neck region 12365.

Once inserted, the locking system 1238 is inserted into the bottom of the club head 1200 through the inner chamber 1242 and by the locking system 1238 and the locking structure 1211 disposed in the handle joint 1202. In connection, the handle joint 1202 and the head joint 1224 can be locked with the club head 1200. If desired, the head joint 1224 will meet the position of the club head 1200 (eg, the mounting ridge 1243 and/or the neck opening) and/or the locking system 1238 will meet the club head 1200. An elastic material (such as a gasket, bushing, O-ring, elastomeric gasket or coating, etc.) may be included to provide noise and/or vibration reduction effects and the like. This exemplary connection system is easily released, such as by unscrewing the screw member 1238. If desired, the screw 1238 and the inner chamber 1242 can be configured to prevent the screw 1238 from completely coming out of the inner chamber 1242 when the screw 1238 is released from the handle joint 1202 (eg, by the screw 1238) An expansion ring is provided on the free end). The screw 1238 can include a head having a structure for engaging a screwdriver, an LLEN wrench, or other tool.

Since the axis of the perforation 1218 of the shank joint 1202 is offset from the axis of the outer surface of the shank joint 1202, and since the axis of the perforation 1231 of the head joint 1224 is offset from the axis of its outer surface, the joints are relative to the Rotation of the club head 1200 will change the position of the shank member 106 relative to the ball striking face of the club head. As detailed above with respect to the previously illustrated structure, this feature, along with the releasable connection system 104, allows the club analyst (or others) to freely and easily adjust the handle member 106 relative to the club head. Various angles and/or positions of the portion 102 (eg, various lying angles, loft angles, and face angle combinations) while still using the same handle 106 and/or head 102, which facilitates the user's ease The optimum club head/handle combination and configuration is determined to suit its needs.

2. Other illustrated handle joints / head joint assemblies

Figures 13A and 13B show an adjustable handle joint/head joint assembly in accordance with another exemplary construction of the present invention. The handle joint/head joint assembly depicted in the cross-sectional view of FIG. 13A and the exploded view of FIG. 13B is similar to the illustration depicted in FIGS. 7-9 and 12A-12B. structure. Therefore, the discussion herein will refer to the illustrated structures of Figures 7-9 and 12A-12B.

The illustrated handle joint 1302 is similar to the illustrated handle joints 702 and 1202 described above, wherein the outer surface of the handle joint 1302 can be fully or partially defined by key teeth 1304 extending along the longitudinal axis of the handle joint 1302 (eg, Figure 13B)). The handle joint 1302 can be made of one or more suitable materials as described above, and can comprise a different material than the material included in other sections of the golf club. For example, the handle joint 1302 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material.

The shank joint 1302 is generally cylindrical and has a first end 1306 and a second end 1310 along the same axis. According to the illustrated construction depicted in Figures 13A-13B, the diameter of the handle joint 1302 can taper from the first end 1306 to the second end 1310. As shown in FIG. 13B, the first end 1306 can include an outwardly projecting region 1312 that seats against and mates with a first end 1326 of a head joint 1324. The handle joint 1302 further includes a perforation 1318 configured to be attached to a handle member 106 along an offset axis 1320. The off-axis 1320 can be offset from the center neck axis 1322 by about 2 degrees, although the angle of departure can be any angle without departing from the invention, for example, at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5 degrees, at least 4 degrees, or even at least 8 degrees.

According to the illustrated construction shown in Figures 13A and 13B, the perforations 1318 can have a circular cross-sectional shape to, for example, accommodate a conventionally shaped circular shank. The handle joint 1302 can be configured in a plurality of manners relative to the handle joint 202 and the shank joint 1202 as described above such that the perforations 1318 can engage or mate with the shank member 106 such that the fit prevents the shank joint 1302 rotates in the handle member 106. Those skilled in the art will readily appreciate that the combination of the handle joint 1302 and the handle member 106 can be used in a number of different ways.

As shown in Figures 13A and 13B, the outer surface of the handle joint 1302 can have a cross-sectional shape that is defined, in whole or in part, by a key 1304 extending along the axis 1320 of the handle joint. The fingers can form a ridge along the surface that is sized to engage and engage a key in the interior of the head joint 1324, for example, in a fixed position. The keys may be of a size, shape and processing as previously described with respect to Figures 13A and 13B. According to the illustrated construction depicted in FIG. 13B, the fingers 1304 can extend along the second end 1310 of the handle joint 1302. Accordingly, the cross-sectional shape of the outer surface of the shank joint 1302 is configured to fit within the head joint 1324 and to inhibit the size and shape of the shank joint 1302 from rotating relative to the head joint 1324. The fingers 1304 (or polygonal cross-sectional areas) may extend along any length of the outer surface of the handle joint 1302 (or the head joint 1324 or the perforations of the neck region 1316) without detachment The present invention is as previously discussed with respect to the exemplary structures of Figures 7-9 and 12A-12B. Moreover, the zones 1304, 1330, and 1332 can instead have a cross-sectional shape having a regular polygon with from 3 to 20 sides without departing from the invention.

In some exemplary configurations, the outer surface of the shank joint 1302, the shank member 106, and/or the head joint 1324 can be tapered in the axial direction at a location other than a circular cross-section. The diameter of the member decreases from the first end to the second end. This feature can help the handle joint 1302 to be easily fitted to and slid out of the head joint 1324, and/or to avoid the need to maintain extremely tight tolerances in the manufacturing process.

The exemplary structure depicted in Figures 13A and 13B can further include a head joint 1324. The head joint 1324 can be made of one or more suitable materials described above and can comprise a different material than the material of the other segments comprising the golf club, as previously discussed. For example, the head joint 1324 can be constructed of a lightweight metal, a metal alloy, or a polymeric material such as a rigid polymeric material. Referring to Figures 13A and 13B, the illustrated head joint 1324 has a first end 1326 and a second end 1328. As can be seen, the first end 1326 is along the same axis as the second end 1328 (shown as axis 1320 of Figure 13A). The head joint 1324 further includes a perforation 1331 along a second axis 1334 that is configured to receive the handle joint 1302 on the second axis 1334 (the handle joint 1302 in turn receives the handle member 106) ). Thus, the outer portion of the head joint 1324 can extend from the first end 1326 in an axial direction to the second end 1328 (axis 1320), and the perforations 1331 of the shank joint 1302 can be placed in different axial directions. The direction (axis 1334) extends. It will be readily apparent to those skilled in the art from reviewing this disclosure that the two axes of the head joint 1324 can be implemented using a variety of different structural elements and/or combinations of methods without departing from the scope of the invention. The angle difference between the first axis 1320 and the second axis 1334 can be any angle without departing from the invention, such as at least 0.25 degrees, at least 0.5 degrees, at least 1 degree, at least 2 degrees, at least 2.5 degrees, at least 4 Degree, or even at least 8 degrees.

The through-hole 1331 of the head joint 1324 has a cross-sectional shape that can be at least partially defined by a key tooth 1332 extending longitudinally in the through-hole 1331. The key teeth 1332 are shaped to engage and engage the handle joint 1302. The outer key 1304 is in a fixed position. The keys 1332 can also have the dimensions, shape and processing as previously discussed. Thus, the cross-sectional shape of the perforation 1331 can be configured to have a size and shape suitable to inhibit rotation of the handle joint 1302 relative to the head joint 1324. According to the cross-sectional view of Fig. 13A, the handle joint 1302 can be inserted into the through hole 1331 to be engaged with the entire portion thereof. In other embodiments, the head joint 1324 can have a size such that the handle joint can be placed in only a portion of the length of the head joint 1324.

In the particular exemplary configuration depicted in Figures 13A and 13B, the club head 1300 can have a space 1342 defined on the bottom of the club head, the club head being provided with an opening along the axis 1342. The head joint 1324 is placed in the middle. As seen in FIG. 13A, the space 1342 can be defined by the mating face 1336. According to the illustrated construction shown in Fig. 13A, the shank joint 1302/head joint 1324 assembly can be secured to the club head from the bottom of the club head 1300 by means of a gasket 1340 and a screw 1338. However, those skilled in the art will appreciate that there are many different ways to lock the components of Figures 13A and 13B.
