Description

The present invention relates to a snowboard binding according to the preamble of claim 1.

WO 93/14835 describes a snowboard binding which especially for so-called "soft shoes", i.e. Shoes without hard shell, used. The binding has one Binding plate with side walls or jaws for Picking up a shoe. The cheeks are in the heel area Binding plate through a heel wall or a heel part connected with each other. There is a high on the cheeks Leg support arranged to fix the lower leg. The Leg support is around one by its attachment points outgoing axis of rotation swiveling. Furthermore, the But legrest one more vertical to the binding plate Rotatable axis. This is provided by the jaws Elongated holes allowed.

To fasten the shoe in this known binding front and rear straps needed. These are in the Holes provided can be attached to the jaws. When creating the The user positions the shoe first in this way the binding plate that the heel stops with the Leg rest is coming. Then the straps over the shoe laid, excited and determined.

The disadvantage of this known binding is that the straps excited and noticed with every boarding and then to to be able to get out of the bond, completely released again Need to become. These manipulations are cumbersome because the hands are usually protected with gloves.

DE-A-44 16 023 discloses a snowboard binding with a Tread element, which is transverse to the longitudinal extent the extending axis A2 is pivotable. At the A tension loop is arranged on the tread element in the closed position of the binding in the tensioned state reaches over the back of the shoe and the shoe in the binding holds. With the binding open, with the flip open The shoe can be comfortably tied into the binding be introduced. By stepping on the shoe The step element becomes this together with the tension loop pivoted downwards and in the closed position against Fold up automatically locked.

The object of the present invention is a To provide snowboard bindings that meet the requirements largely avoids the disadvantages mentioned. In particular, should the new snowboard binding makes it easy to get in and out allow out of the bond. In addition, the bond should suitable for different shoe sizes and types and be produced as simply and inexpensively as possible can.

According to the invention, this is the case when the entry is bound realized in such a way that the Locking means are designed such that the Swivel part lockable in different swivel positions is. The swivel part is used to close the binding folded down and found. Finding the Swivel part can e.g. by means of a snap lock or by means of other locking means, which the Swivel part in one or in many arbitrary positions Can be detected. A front and are expedient a rear strap, band or the like is provided, which are arranged on the swivel part. The use of a single larger clamping part, which with the Back of the shoe can work together is also conceivable. The Straps can be made of plastic or textile material.

In a particularly advantageous embodiment, the Swivel part of a shoe sole pad. This can for example by a plate, by a web or be formed by inwardly projecting projections on which the shoe can rest. The shoe pad allows that Swivel part with the shoe in the locking position bring. The entry can be made so that the Front part of the shoe through the swivel part and the straps formed opening introduced and then through the swivel part a foot movement is pivoted into the locking position. The shoe automatically comes into contact with the Leg support and is clamped by this and the straps. The swivel part is then in the locking position Locking means, e.g. a snap lock, locked. To the Only the locking device needs to be released be loosened so that the swivel part moves with the shoe swiveled up and the shoe can be pulled out. in the There is a difference to the binding mentioned at the beginning Embodiment when boarding usually no further manual operations are more necessary, i.e. it doesn't have to Straps more loosened or tied. The clamping of the shoe in the binding takes place essentially through the Own weight of the shoe wearer. However, it can very well additional tensioning means of a known type on the straps are used.

In an advantageous embodiment, the Swivel part two arms, the arms by at least one Bridge are interconnected. The web can be used as Serve shoe sole pad. This swivel part can be used as Stamped part made of sheet metal and then in the correct shape. However, it can also be used in Injection molding process made of plastic. As Locking means for the swivel part can be snap locks be provided with latch. The bars can be used with a or a variety of recesses on the arms work together.

The binding plate expediently has two side walls or bake. The jaws can be used as the swivel part Guide and / or in the folded down position as serve side stop. The cheeks also take care of you good lateral hold of the shoe in the binding. Furthermore can the legrest and parts of the Locking device may be attached. It can be advantageous Snap the web between the jaws. In an expedient Embodiment is the web in the folded down Position flush with the surface of the binding plate. This can e.g. through a corresponding recess in the Binding plate or by shoe soles on the Binding plate can be reached.

The leg support advantageously serves the shoe when getting in as a guiding surface, i.e. the shoe is when you fold down the Swivel part pushed slightly forward by the legrest, which creates the necessary tension for a firm hold becomes. The legrest is not only used as a stop for the shoe neck, but acts like a shoehorn.

The straps are advantageously adjustable in length. This allows binding to different shoe sizes be adjusted. The straps expediently have additional clamping devices.

The leg support on the binding plate is advantageous articulated and pivotable. This has, for example Advantage that the leg support for transportation or storage purposes can be placed on the binding plate. The leg support is expediently in the heel area of a heel part (also called "heel"). The Heel part can be used as a stop and reinforcement for the Serve leg supports. The positions of the Leg support and the heel part independently on the Binding plate adjustable. This allows for example, adjust the angle of the legrest. It is also conceivable to use the legrest on the heel part to arrange, or if the legrest on the binding plate is arranged to omit the heel part.

This is another embodiment of the binding characterized in that the arms of the swivel part by a Brackets are interconnected. The bracket can be used as a handle serve to operate the swivel part. With the the preferably stable and stable is the closing and Opening the binding is even easier to do. It is basically conceivable to use the strap instead of a strap (strap) to use.

The strap and the strap are advantageous with the Poor connected. This can cause the bond to adjust different shoes. The are also advantageous Strap and the strap on the arms in a certain area pivotable.

The locking means are expediently such trained that the swivel part in different Swivel positions can be determined. For example Buckles and timing belts interacting with the buckles be the swivel part on each side with the Connect the binding plate. Well-known are preferred Ratchet buckles for use. The ratchet buckles can on the bracket and the toothed belt on the jaws of the binding plate be arranged, although the reverse arrangement also is possible. To determine the swivel part can also Snap locks with bolts are used, which with one or a plurality of recesses on the arms can work together.

An advantageous embodiment provides that the loose Timing belt ends in a space between the Extend strap and strap. For this purpose the Strap above the buckle have a cutout which the toothed belt ends can extend. The Toothed belt ends can have a stop, which a prevents accidental escaping from the buckle.

The buckles or bolts are particularly advantageous a band, a cable or the like together connected so that the buckles or bolts by pulling the Belt or cable can be opened at the same time can. This allows a quick exit from the bond, without cumbersome manipulations. It can two or more buckles connected together his. The tape can be used for better usability Have a handle or a loop. In an expedient Execution is the band or the cable pull by two in Openings of the temple provided from the top of the temple led and extends through the recesses to the Actuating lever. However, it is also conceivable to use the tape to be placed above the bracket.

The bond 11 shown in Figure 1 consists in essentially from a base or binding plate 13, one Leg support 15 arranged on the rear of the binding plate 13 and a swivel part 17. The legrest 15 is in Technical jargon also called "spoiler". The special thing about the Binding 11 is that for closing or opening the binding 11 only the swivel part 17 downwards or upwards needs to be pivoted (arrow 18). In contrast to The binding described at the beginning are the front and the rear strap 19.21 (also called "strap") not on the Binding plate 13 but arranged on the pivot part 17, i.e. the belts 19, 21 move with the swivel part 17 The user enters the binding Shoe front part only in the by the straps 19,21 and the pivot part 17 formed opening and presses then the shoe with its own weight or manually downward. The heel of the shoe then slides on the Legrest 15 down until the swivel part 17 in the Locking position snaps into place.

In the exemplary embodiment in FIG. 1, the swivel part is 17th by two rails connected by means of a web 23 or Arms 25 formed. The arms 25 are at the front end Pivotal point 27 is pivotally connected to the binding plate 13. The swivel axis runs transversely to the longitudinal axis of the binding. The Web 23 gives the swivel part 17 a certain stability and allows the swivel part when getting into the binding 17 with the shoe, i.e. without manual intervention, in the Bring locking position. Basically, it can Swivel part 17, if no web 23 is provided, too be closed manually.

The leg rest 15, which is usually made of plastic is made of a metal, stationary heel part 29 (also called "heel") surrounded. The Heel part 29 can act as a stop for the pivoted Leg support 15 serve. Basically, the stop for the legrest 15 also realized in some other way his. On the heel part 29 there are two snap locks 31 provided which with recesses 33 on the arms 25th can work together. One or 25 can be on an arm a plurality of recesses 33 or snap positions be provided. Another embodiment provides that Swivel position of the swivel part using toothed belt and Buckles on both sides of the swivel part are intended to be established.

An appropriate snap lock 31 has one spring-loaded bolt or bolt 35, which can snap into a recess 33 on the arm 25 if that Swivel part 17 is in the locking position. 25 on each arm can have one or a plurality of locking positions be provided (in Fig. 1 shows the purpose of simplifying the rear arm 25 two recesses 33 and the front arms a single recess 33). Basically, they can releasable locking means for the pivot part 17 on the different types. You can for example, either on the heel part 29 or on the Binding plate 13 or on the swivel part 17 (see second Embodiment below) may be provided.

The locking means can preferably be by a solve only manipulation. In the embodiment shown are the latch 35 for this purpose by means of a cable 37 connected to a rotatably mounted disc 39. By Both of the disks 39 can be rotated in this way Open snap locks 31 at the same time (arrow 41). It is also conceivable that locking means having spring means are provided, which are under a certain force open by itself, i.e. the locking means can at the same time a safety or trigger function hold.

The position of the heel part 29 and the legrest 15 are adjustable on the binding plate 13. For this purpose in the side walls or jaws 43 of the binding plate 13 a series of holes 45 are provided. The holes 45 serve the inclusion of screws 47 with which the heel part 29 and the legrest 15 can be fixed on the binding plate 13 are. The legrest 15 is attached by means of two screws 47 the jaws 43 pivotally arranged.

The straps 19, 21 are adjustable in length. Also their position on the rails Arms 25 is adjustable. Thereby the bond 11 can be attached in a simple manner adjust different shoe sizes. A Position adjustment is made through a series of holes 49 or made possible by slots 51. At least the back one Belt 21 also preferably does not have any details shown tensioning means 53, which tightens the belt 21 enable. For this purpose, the belt consists of two parts connectable by the clamping means 53. The front one Belt 19 is also in two parts and does not have one Locking device 54 shown in more detail are conventional as front and rear straps 19.21 Plastic timing belts and interacting with them Buckles used.

The pivot part 17 is in the folded down position through the side walls or jaws 43 against a side Shear fixed. In addition, the web 23 is shaped (in Figure 1 not visible) that he is in the folded down Position of the pivoting part between the jaws 43 comes to lie. The web 23 is then preferably flush with the surface of the binding plate 13. For this purpose a corresponding recess in the binding plate 13 can be provided or it can be in the front and rear Binding area shoe sole pads may be provided.

The binding plate has one in the middle circular opening 55, which fixes the binding 11 serves on the snowboard. Are at the size of the opening radial ribs or the like provided (not in Figure 1 evident), which with a corresponding on the Snowboard attachable counterpart can interact. This allows the binding plate 11 in any angular position with respect to the longitudinal axis of the snowboard determine.

The second shown in Figures 2 to 8 Embodiment 11 'has two arms 61 having swivel part 17 '. As in the first Embodiment are the two straps ("strap"), the front strap 19 'and rear strap 65 on arms 61 attached. The straps 19 ', 65 act when the belt is closed Binding with the back of the shoe together.

Two serve as locking means for the swivel part 17 ' Buckles 67, which each have a tooth 69 Toothed belt 71.73 interact (Fig. 2b and 10). The Toothed belts 71, 73 are in the heel area of the binding plate 13 'attached to the jaws 43'. Attachment directly to the Heel part is also conceivable. The buckles 67 are on the leg of a U-shaped bracket 63 is arranged (FIG. 5), which together with the belt 65 by means of one of the Figures of bolts not visible on the arms 61 is articulated. For this purpose there are two in belt 65 Round holes 79 are provided and two round holes 80 a in the bracket 63 (Figs. 5 and 6). The arms 61 each have one at the rear end Slot 83 (Fig. 7). The elongated hole 83 describes a curve which allows the strap 65 and the bracket 63 to be closed pivot without the pivot position of the arms 61 would be changed significantly (pivot axis 80b). This can Depending on the type of shoe, the strap 65 optimally adapts to the Put on the back of your shoes. The bolt mentioned above Attachment of the bracket 63 and the belt 65 is used expediently also the fastening of the buckles 67th

The front, two-part belt 19 'is by means of screws 75 releasably attached to the arms 61 (Fig. 2a and 2b). Elongated holes 77 allow the position of the front belt 19 '. The length adjustability of the front Belt 19 'serves a simple ratchet buckle 68.

Basically, 71.73 can be used to lock the toothed belt any known locking devices used become. Ratchet buckles are the most advantageous used with an integrated clamping device. A advantageous ratchet buckle 81 with an integrated Clamping device consists essentially of three pivotable stored levers, namely a locking latch 83, a Actuating lever 85 and one on the actuating lever 85 pivoted clamping tooth 87 (Fig. 8; pivot axis 88). The clamping tooth 87, the function of which is still below Detail is described, allows tightening the rear Timing belt with the operating lever 85.

The ratchet buckle 81 has a U-shaped cross section Buckle body 89, on which the locking latch 83 and the operating lever 85 are pivotally arranged (Swivel axes 91 or 93). A closing spring 95 stops the rest position of the actuating lever 85 the locking latch 83, the front end of which is designed as a locking tooth 97, in engagement with the one passed under the levers 83, 85 Timing belt 71 or 73 (Fig. 8a and 8b). In the release position (Fig. 8c) presses the operating lever 85 with a bead 99 onto the rear end of the locking latch 83 and lifts the Locking tooth 97 on, so that the toothed belt 71.73 in Is displaceable in the longitudinal direction.

The teeth 69 of the toothed belt 71, 73 are asymmetrical educated. They have an inclined surface 101 and one vertical flank 103 (Fig. 8a). The edge 103 serves as Stop for the locking tooth 97. The inclined surface 101 allows the toothed belt 71.73 in the rest position of the Actuating lever 85 in the direction of arrow 105 through the Slide buckle 81. The slips under Locking latch 83 spring-loaded over surface 101 of a tooth 69.

The front end of the clamping tooth 87 has two teeth 107, 109 on which engage the teeth 69 of the toothed belt 71, 73 can. A spring 111 holds the clamping tooth 87 in the Rest position of the operating lever 85 in one Working position (Fig. 8 a and c, Fig. 9). In the The working position is the front end of the Chuck tooth 87 at a distance from the operating lever 85 and that the rear end lies against the buckle body. When depressing of the actuating lever 85 reach the prongs 107, 109 of the Tension tooth 87 engages teeth 69 of toothed belt 71 or 73 (Fig. 8b). The operating lever 85 continues after pressed down, the tension tooth 87 pushes the toothed belt 71, 73 by at least one tooth 69 through the buckle 81 (arrow 105). The locking tooth 97 of the locking latch 83 slips over the inclined surface 101 of the next posterior tooth and comes into engagement with the flank 103 thereof. Will the Operating lever 85 opened again, the teeth now slide 107,109 of the clamping tooth 87 over the surface 101 of the respective next rear tooth 32. Thereby the clamping tooth 87 first against the force of the spring 111 against the Operating lever 85 pressed. Once the spikes over 107,109 the top of each tooth has slipped, brings the Spring 111 the prongs 107 and 108 of the clamping tooth 87 back in Distance to the operating lever 85 (working position) and the Chuck tooth 87 can then engage teeth 69 again. so - if necessary - a new clamping process can take place. The ratchet buckle 81 described is characterized by the fact that the Timing belt can be tightened by two teeth.

A peculiarity of the second embodiment according to Fig. 2 is that protruding from the buckles 67 Ends of the timing belts 71,73 in one between the bracket 63 and the belt 65 provided space can. For this purpose, the legs of the bracket are on which the buckles 81 are arranged in a step-like manner set off inside (Fig. 5). Are above the stirrup legs Recesses 113 are provided. The mounting surface 114 for the buckle 67 is directed obliquely inwards so that the toothed belt ends unhindered by the recesses 113 can extend.

As shown in FIG. 4c, the toothed belts are 71, 73 partially curved (approximately anterior half). The curvature is the radius of the bracket 63, respectively. the arranged on the bracket Belt 65 adjusted. This has the advantage that when Close the binding 11 'of the toothed belt ends on the bracket 63 or do not knock on the belt 65 or only slightly. The Curvature of the toothed belt 71, 73 is advantageous different, so that the toothed belt end faces at The binding cannot meet (Fig. 10). The fact that the toothed belt 71.73 between the Belt 65 and the bracket 63 extend, are the Timing belt ends practically invisible from the outside. This is aesthetically more beautiful on the one hand and on the other hand also expedient, since a back and forth flutter from the Buckle 67 outstanding timing belt ends from one Snowboarders would find it annoying when driving.

The roughly semicircular "strap" in cross section or Belt 65 has a circumferential direction Well 115 (Fig. 6). The recess 115 serves the Recording and guiding the toothed belt 71.73. However, it is possible to omit the recess 115 and instead a sufficiently large distance between the bracket 63 and the Comply with belt 65. At the bottom of the belt 65 are pads are usually provided (not shown), to clamp the shoe as evenly as possible.

The actuating lever 85 as a locking and Ratchet buckles 81 serving for tensioning are by means of a band 117 connected to each other (Fig. 2 and 10). This allows the ratchet buckles to be pulled by pulling the strap 117 can be opened at the same time. The band 117 extends by two provided at a distance from the top of the temple Openings 119 in the bracket 65, then runs on the underside of the bracket 65 and extends through the recesses 113 to the operating levers 85. The ends of the band 117 are in a slot 121 of the respective operating lever 85 attached (Fig. 9). For this purpose, the band 117 is through the slot 121 looped, and the tape end like this folded back and sewn together that a straddled Band end 123 is formed. This stripped band end 123, once passed through the slot 121 in the actuating lever 85, can hang on the edge of the slot and a looping out of the Prevent tape 117. The band 117 has on top of that Strap 63 has a loop 124, with the aid of which the band 117 can be better captured.

In order to close the binding on a possible Overlap of the toothed belts 71, 73 a collision of the To prevent end faces of the toothed belt 71, 73 as far as possible the front ends of the timing belts are tapered in thickness (Toothed belt 71) or wedge-shaped (Fig. 3b and 4a and 4b).

At the front end, the timing belts 71, 73 have one Stop 125 resp. 127. The stops 125, 127 act either with the strap 63 or the buckle 81 together and prevent the timing belts 71.73 from accidentally the buckle 81 can be looped out (Fig. 10). It however, the front ends are conceivable for the same purpose the buckles 81 only to be provided with a thickening. The buckle can be in a certain position Lever 85 allow the toothed belts 71, 73 to be pulled out, this lever position preferably by overcoming a certain resistance, e.g. Spring force, adjustable is. Another option is to use the To connect the toothed belt ends with a band so that when the binding is opened, it does not Buckles can be pulled out.

The different embodiments of the new described Bindings are particularly suitable for fixation so-called "soft shoes" on a snowboard. By the Providing a swivel part can make the binding simple and can be quickly closed or opened. Also ensures the swivel part for a good hold of the shoe. The connection can be made partially or entirely of plastic.
