background

Golf is loved by a wide variety of players - players of different genders and great age differences and / or technical standards, and the uniqueness of golf in the sporting world is that even if they compete directly with each other (for example, using handicap, different serve) In the case of teams, team formations, etc., these various players can also play together in the golf game and still love this golf game or competition. These factors are at least partially caused by the growing number of golf programs on television (eg, golf tournaments, golf news, golf history, and/or other golf programs) and famous golf superstars. The golf population has increased in the United States and the world in recent years. The number of people participating in golf tournaments and the number of golf courses have also steadily increased in recent years.

All technical level golfers will want to improve their performance, reduce their golf clubs and reach the next performance level. Manufacturers of various golf equipment have responded to these needs, and in recent years, the industry has witnessed significant changes and improvements in golf equipment. For example, a variety of different golf models are now available to make the ball available for use, for example, some balls designed to fly farther and/or straighter; some designed to provide a higher or flatter trajectory Ball; some balls designed to provide more rotation, control, and/or sensing (especially around the green); some are set to fit a slower or slower swing ball to complement a particular swing Speed and / or other player characteristics or preferences. In addition, many of the promises that help reduce the number of golf clubs and/or teaching aids are also available on the market.

As the only instrument for moving a golf ball while playing, golf clubs have been researched and advanced in recent years. For example, significant changes and improvements have been seen in the market for putter designs, golf club heads, shafts and grips. In addition, there are other techniques (such as club adjustment techniques, in terms of adapting the various components and/or characteristics of the golf club and/or the performance of a golf ball to better match the swing characteristics or characteristics of a particular user. The progress of the ball hitting angle measurement technique, the ball rotation speed, and the like.

Despite recent advances in technology, "wood-type" golf clubs, particularly kick-off woods, are difficult for some players to consistently and well hit. Therefore, the improvement of the player to lift a golf ball; increase the distance, direction and control; and / or improve the wood-type golf clubs, especially the ability of the kick-off wood to hit the ball will be in the golf world. Popular in China.

Additionally or alternatively, at least some portions of the bottom member (e.g., portions 102c and 102d) may be made of a composite or other non-metallic material, if desired. If desired, in other examples or alternatives, one or more portions of the body member of the club head (the region extending between the crown and the bottom) may be comprised of a composite or other non-metal Made of materials. If desired, in still other instances, the body portion of a club head member, or the entire club head, may be formed from a composite or other non-metallic material without departing from the invention. The composite or other non-metallic material can be combined into a portion of the club head structure 102 in any desired manner and reduce the weight of the club head (eg, using composite or other non-metallic materials, lightweight metals, metals) Foaming material or other material having a cell structure, etc.) allows the club designer to selectively attach additional weight throughout the club head structure, for example, at most desired locations to increase the moment of inertia and/or affect the Other hitting characteristics of the club head structure 102.

The individual components that make up a club head structure 102, if made of a plurality of components, can be combined and/or held together in a suitable or desired manner, as is known in the art and used in a conventional manner. For example, various components of the golf club head 102 such as the base member 102a and the composite (or non-metallic) portions 102b, 102c, and/or 102d may utilize adhesives, adhesives, brazing, soldering, or the like.

Fixedly connected together.

The dimensions and/or other characteristics of the golf club head structure of the present invention may vary substantially without departing from the invention. In some particular instances, at least some of the club head examples of the present invention may have a fall in May 2005. Examples of sizes and/or characteristics of various club heads disclosed in U.S. Patent Application Serial No. 11/125,327, the entire disclosure of which is incorporated herein by reference. Size and/or other characteristics within the scope. Please note, for example, in the tables of these documents, which are hereby incorporated by reference in its entirety in its entirety.

As previously mentioned, at least some of the club heads 102 of the present invention may have a relatively "square" or rectangular shape or appearance, particularly when viewed from above and down the crown of the club head, such as Figure 1A shows. Figure 1A further shows that the club head 102 has a full length dimension L in the heel to toe direction and a full width dimension B in the front to back direction. In some examples of the invention, in the club head construction, the ratio of the width dimension to the length dimension ("B/L") will be at least 0.9, and in some instances, the ratio may be at least 0.92. At least 0.93, at least 0.94, at least 0.95, at least 0.96, at least 0.97, or even at least 0.98.

The relatively "square" or rectangular shape or appearance of at least some of the golf club head examples of the present invention is advantageous because it imparts weight in the club head structure 102 (eg, using composite materials, lightweight metal alloys) The reduced weight of the chamber metal or other material, the metal foam material, the polymeric material, etc. can be selectively placed in the club head structure 102, for example, toward the rear of the club head structure 102, toward the The heel and/or toe regions of the club head structure 102 are disposed and/or toward the bottom of the club head structure 102. These weight structures help to increase the moment of inertia of the club head, particularly its moment of inertia centered on a vertical axis (such as Izz).

There are various ways to evaluate the "square" of a club head structure (such as angle and side orientation), and one of the methods uses the "theoretical maximum diagonal dimension" of the club head. FIG. 1E facilitates the display of this "square" measurement tool. In detail, FIG. 1E shows a club head structure 102 having a 1A surrounding the boundary block of the club head body 102. The boundary block is tangent to the outer surface of the club head body (at its maximum width and depth points), and the boundary block is formed by club heads that are disposed at right angles to each other to define the corners of the boundary block The length dimension L and its width dimension B (which form the four sides of the boundary block) are defined. Thus, when viewed from above, the boundary block defines a rectangular configuration along the major sides of the club head 102 along the four major sides of the club head 102 (eg, enclosing the club head body 102) The smallest rectangle).

The boundary block also defines the theoretical maximum diagonal dimension, and the theoretical maximum diagonal dimension extends from one corner of the boundary block to its diagonal opposite angle 隅. The diagonal dimension is the theoretical maximum diagonal dimension of a perfect square or rectangular club head (ie, if the club head 102 is perfectly square or rectangular, and each corner is a right angle and its opposite sides are parallel to each other, Then its diagonal dimension will be the length from point D ₁ to D ₄ in Figure 1E (corresponding to length (B ² + L ² ) ^1/2 ). However, the club head 102 is not a perfect "square" or Rectangular. Therefore, its full diagonal dimension D along the same diagonal (ie, from point D ₂ to D _{3 in} Figure 1E) is less than the length from point D ₁ to D ₄ (or less than (B ² + L) ² ) ^1/2 ). In at least some examples of the invention, the true full diagonal dimension of the club head (e.g., from points D ₂ to D _{3 in} Figure 1E) will be at least 0.75 x (by The length of points D ₁ to D ₄ in Fig. 1E) or at least 0.75 × (B ² + L ² ) ^1/2 ). In some examples of the club head structure of the present invention, the true full diagonal dimension of the club head (e.g., from point D ₂ to D _{3 in} Figure 1E) will be at least 0.8 x (by Figure 1E) The length of the points D ₁ to D ₄ ) or at least 0.8 × (B ² + L ² ) ^1/2 ), at least 0.85 × (the length from the points D ₁ to D ₄ in the 1E diagram) or at least 0.85 × (B) ² + L ² ) ^1/2 ), or even at least 0.9 × (the length from the point D ₁ to D ₄ in the 1E diagram) or at least 0.9 × (B ² + L ² ) ^1/2 ).

If desired, in the example of the present invention, one or both diagonals of the club head structure 102 (i.e., the diagonals from points D ₂ to D ₃ in Figure 1E and/or from Figure 1E) The diagonal points D ₅ to D ₆ may have the aforementioned dimensional characteristics. The (equal) diagonal may be at a vertical height or position throughout the club head structure 102, ie, the club head body cross-section encloses or encloses a maximum total area (eg, to provide the club head) The maximum true diagonal dimension D) is measured, or it can be measured along the diagonal using the widest point on the club head body, regardless of the vertical height position of these widest points, as shown in Figure 1E. (Also known as "full diagonal size").

In the structural example shown in FIG. 1E, the length from D ₁ to D ₂ along the diagonal D (also referred to as "the opening portion of the diagonal") may be less than 1 inch, and in some In the example, it is less than 0.75 inches, or even less than 0.5 inches. Generally, the smaller the opening portion of the diagonal size, the more "square" or rectangular the structure.

Another way to evaluate the "square" of a club head is to use a horizontal cross-sectional area enclosed or surrounded by the club head (eg, horizontally relative to the club head orientation during normal use, for example, when pointing and / Or hitting a golf ball or the club head is disposed on its shaft angle and/or placed on its bottom plate, as shown in FIG. 1E, if the club head 102 is a perfect "square" or rectangular (ie, The front, rear and side edges are vertically arranged in a rectangular configuration), at least one horizontal cross section of the club head will enclose or enclose a ball head length (size L) and width (size B) The maximum theoretical area of the area = B × L). Because the true club head 102 has a slightly rounded corner and/or curved edge, the maximum horizontal cross-sectional area surrounded by the outer peripheral edge of the club head 102 is less than the maximum theoretical area = B x L. In at least some examples of the invention, the golf club head 102 will include at least one horizontal cross-section (when the club head is oriented for general use, on its bottom, and/or at its desired pole) The body angle, or a plurality of horizontal cross-sections, enclose or enclose an area of at least 0.75 x BL, at least 0.8 x BL, at least 0.85 x BL, at least 0.9 x BL, or even at least 0.95 x BL.

As previously mentioned, the generally "square" or rectangular configuration of the golf club head of the present invention allows the additional weight to be located deep within the club head structure (toward the club head), wide (toward the club head heel and / or toe), and / or low (toward the club head bottom). 2A to FIG 2C show various examples, Specifically speaking, the display of FIG. 2A and 2B include at least one of the two separate weight member W _{W. 1} and ₂ of the club head structure 200, and the weight _{member. 1} W The W ₂ system is disposed below and below the club head structure 200. The structure 200 of this embodiment, the weight member those wherein one or both of W detachably mounted in the ₁ and W ₂ on the club head structure 200, and a removable, replacement, exchange, order By. In the illustrated configuration 200, a larger (or heavier) weight is placed toward the heel side of the club head structure 200 to strike a preferred left curved ball (eg, providing a left-handed curve) The club is used to correct a right or over-right ball flight path). Of course, the club head structure 200 can have a plurality of different mass weights and/or a plurality of counterweight positions for receiving the weight members W ₁ and W ₂ (including at different heights in the club head structure 200) Holes) for a variety of redirection and customization options (for example, providing a left-handed curved club, providing a right-handed curved club, providing a help to compensate for unnecessary ball flight paths or swings (such as assisting with corrections) Left curved ball, right curved ball, etc., assisting in lifting the ball, preventing the balloon from rising, etc.). In a more specific example of the first display is configured to FIG. 2C slightly differently to the weight member and the club head structure 250 (e.g., W ₁ and W _2). If necessary, the weight structure of both the 2B and 2C diagrams can be placed in a single club head structure (for example, in Figure 2C the weight hole position is slightly higher than the weight hole in Figure 2B). Position and / or inside the weight hole position in Figure 2B).

Also, any number (zero, 1, 2, or greater) of weight members may be provided in a club head structure 200 without departing from the invention. One or more of the available counterweight holes may remain empty in a club head configuration, if desired. When detachably connected, the (equal) weight members (eg, W ₁ and W ₂ ) can be attached to the club head structures 200 and 250 without departing from any desired manner of the present invention, including Conventional means known and used in the art, such as through mechanical connectors (such as screwing, etc.), fastening systems, adhesives, and the like.

Any of the weight members including, for example, tungsten-containing or lead-containing members, including tungsten or lead elements, tungsten or lead alloys, tungsten-containing or lead polymers, and the like, may be provided without departing from the invention. Meanwhile, although FIGS. 2A to 2C show separate and independent weight members (for example, W ₁ and W ₂ ), this need not necessarily be the case. Conversely, a single weight member that can have a variety of different sizes and/or densities can be provided along at least one dimension, if desired. In another example, the body of the club head structure (e.g., structure 102) can be integrally formed, if desired, to provide a counterweight in one or more regions, which can be without departing from the invention. , in any way desired. For example, the weight region can be provided using a weight material comprising a metal (e.g., tungsten or lead), a composite material, or other structural material of the club head structure 102 at the desired rear, bottom, and side portions. In another example, the weight region can be made from a thicker metal (or other) material to the desired portion of the club head structure 102 or from a different heavier metal (or other) material, if desired.
