Abstract

A snowboard binding has a cruciform base clamp (4) that engages with a cam clamp (6) via a square plate (3) and circular top plate (2). The central aperture (10) in the square plate (3) is considerably larger than the base clamp central spigot (5), allowing adjustment of the spigot position within the surrounding aperture (10) in two directions (x, y).

Description

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

Such a bond is known from EP 0 351 298 A2. This binding has a base part that is attached using screws can be attached to the surface of a snowboard. The Base part has a recess in the form of an elongated hole, through which a pin protrudes from a clamping plate protrudes between the bottom of the base part and the top of the snowboard is arranged and the is displaceable in the direction of said slot. A base plate of the binding can be placed on the base part, wherein the base plate has a recess, through which the mentioned pin protrudes through. On the base plate are the usual fasteners for holding a Shoe attached to the base plate. Above the base plate a hold-down plate is arranged, the one in the middle Has recess through which a screw is inserted and can be screwed into a thread of the mentioned pin of the clamping plate is. When tightening the screw the base plate between the hold-down plate and the Base plate fixed by holding down plate the clamping plate is pulled. By loosening the screw can the entire unit from clamping plate, base plate and Hold-down plate moved in the slot in the base plate with which the position of the binding in a longitudinal direction is adjustable. The screw has an operating bracket so that they can also be clamped by hand without tools and can be solved.

EP 0 840 640 B1 shows a similar binding in which but the base plate with an elongated hole in the body of the snowboard is embedded and with a box-shaped profile has a longitudinal slot. A similar bond is also there shown in DE 295 01 515 U1, in which also a Guide profile embedded in the body of the snowboard is. Instead of a hold-down plate there is only one Central screw provided by an appropriate Hole in the base plate passes through. Such a bond is also shown in FR 25 75 660 A1.

All of the bonds mentioned have in common that the position the binding in the longitudinal direction of the snowboard simple and can be adjusted without tools, the fixation the binding in this prior art always by frictional forces he follows. Some of these ties, like e.g. EP 0 840 640 B1 and EP 0 351 298 A2 is additional also the rotational position of the base plate in relation to a Axis of rotation perpendicular to the snowboard surface adjustable.

FR 26 27 097 A1 and WO 98/08480 A1 show snowboard bindings, where only the rotational position of the base plate is changeable without tools. On the FR 26 27 097 A1 are linearly movable racks on a rotating plate attached, which engage in a counter toothing. The Moving the racks is done with a lever, which the toothing can be opened or closed. at WO 98/08480 A1 is the base plate on a rotary plate attached, being on the turntable a perpendicular to the snowboard surface movable locking pin is attached, which can be snapped into holes in a counter plate.

With the latter bindings, only the rotational position is adjustable, but not their position in relation on the surface of the snowboard.

All of these ties have the essential purpose, the particular one Adjust easy to shape, so these ties are especially suitable for snowboard rental, where the Binding often needs to be adjusted to other drivers. Such bonds are also suitable for people who want their Find out the optimal position of the binding experimentally want a quick one without tools, even on the slopes want to try another binding position or orientation.

• in Längsrichtung des Snowboards
• in Querrichtung des Snowboards und
• in Bezug auf eine senkrecht zur Snowboardoberfläche stehende Drehachse,

wobei die Verstellung möglichst stufenlos oder feinstufig erfolgen sollte. Dabei ist es - wie beim genannten Stand der Technik - wünschenswert, wenn die Verstellung einfach und ohne Werkzeug vorgenommen werden kann. Schließlich soll die jeweils eingestellte Position auch bei hohen Kräften, wie sie beim Snowboardfahren zwischen Bindung und Snowboard auftreten, sicher beibehalten werden.In general, the position and orientation of a snowboard binding should have three degrees of freedom, namely

• in the longitudinal direction of the snowboard
• in the transverse direction of the snowboard and
• in relation to an axis of rotation perpendicular to the snowboard surface,

the adjustment should be as smooth or as fine as possible. As with the prior art mentioned, it is desirable if the adjustment can be carried out easily and without tools. After all, the position set in each case is to be maintained reliably even with high forces, such as occur between snowboard binding and snowboarding.

The object of the invention is therefore the one mentioned at the beginning Improve snowboard binding so that they have three Has degrees of freedom of adjustment, each set position is safely maintained and the adjustment is easily possible.

This object is achieved by the specified in claim 1 Features solved. Advantageous refinements and developments the invention can be found in the subclaims.

The basic idea of the invention is in the base part to provide a recess which is so large that an adjustment along two axes of a Cartesian coordinate system allow in the plane of the snowboard surface, whereby the position is determined by positive interlocking he follows.

According to a development of the invention, the directions of movement are in the longitudinal direction of the snowboard (x direction) and decoupled from one another transversely thereto (y-direction). For this is between the top of the clamping plate and the bottom the base plate is provided with straight teeth and between the top of the base plate and the bottom the hold-down plate also has a positive connection, which only allows movement in one direction, which transverse to the direction of movement of the first toothing lies.

In another variant of the invention is only between the bottom of the base plate and the top the clamping plate provided a toothing. Preferably the teeth have a pyramid shape and the counter teeth corresponding recesses.

The clamping plate preferably has the top view Shape of a cross with four legs or a star with three legs, with which the base plate is given a given size the adjustment range can be increased because of the legs still between the mounting posts of the base plate can reach through.

an exploded view similar to FIG. 2 of a second embodiment of the invention.

The same reference numerals in the individual figures correspond same or functionally the same parts.

First, reference is made to FIG. 1. The bond will attached to the surface of a snowboard S. This has a base plate 1 on which the usual holding elements for the attachment of a shoe are attached (not shown). For example, it is not shown Instep straps, heel supports, bracket for boot soles or other known holding devices, of which it in the state of the art and on the market a variety of different Embodiments exist.

The binding according to the invention also has a base plate 3, a clamping element 4 with a vertically protruding Pin 5 and a clamping lever 6, with a pivot axis 7 is pivotally attached to the pin 5.

The base plate 3 is over several posts 8, each have a hole 9 on the surface of the snowboard S attached. This is usually done by means of not shown Screws that engage in nuts, which embedded in the body of the snowboard S as so-called inserts are. Most of those on the market today Snowboards are these screw nuts in the pattern of a square arranged with a side length of 4 cm, so that too the holes 9 are arranged in a corresponding manner. Of course it is also possible for other patterns of inserts, for example in the form of an equilateral Arrange the posts and the holes accordingly.

The base plate 3 can be rectangular in plan view (see Fig. 2) or circular (Fig. 3 and 4). By the post 8 it is at a distance from the surface of the Snowboards S held. The base plate 3 has a central one Recess 10, which is preferably rectangular and whose Dimensions the adjustment range in the x and y direction (cf. Fig. 2) sets. Between the surface of the snowboard S and the base plate 3, a clamping element 4 is arranged, from which a central pin 5 vertically upwards in protrudes z-direction and through the recess 10 of the base plate 3 reaches through. This pin also engages 5 also through an opening 11 of the hold-down plate 2, so that this is coupled to the clamping element 4 via the pin 5 is. The cross section of the pin 5 and the opening 11 are preferably rectangular or square, so that the clamping element 4 and the hold-down plate 2 in the direction of rotation c are positively coupled.

The pin 5 has a transverse bore 12 through which the clamping lever 6 can be fastened by means of a pivot axis designed as a pin is. This pin 7 is by a corresponding one Bore 12 'mounted on the tensioning lever 6, the tensioning lever one eccentric with respect to the axis of the pin 7 Has clamping surface 13 on the top of the hold-down plate 2 is supported. By swiveling the swivel lever 6 around the axis of the pin 7 is thus the hold-down plate 2 moved against the tensioning element 4 in the z direction, with which the hold-down plate 2 and the clamping element 4 from above or below against the corresponding surfaces of the base plate 3 are pressed. The arrangement of the eccentric The clamping surface 13 is selected with respect to the clamping lever 6 that by depressing the tension lever 6 a tension and by swiveling up a loosening of the connection mentioned he follows.

In the embodiment of Figures 1 to 3 is between the top of the clamping element 4 and the bottom of the Base plate 3 a toothing 14, 15 is provided, wherein the teeth here extend in the y direction. hereby is achieved that when the teeth 14 and 15 the clamping element still in the y direction compared to the fixed one Base plate 3 can be moved.

At the top of the base plate 3 are several protruding Pins 16, 17, 18 and 19 arranged in associated slot-like recesses 20, 21, 22 and 23 on the underside the hold-down plate 4 engage, these recesses 20-23 formed as blind hole-like recesses are not completely due to the thickness of the hold-down plate 2 go through. These recesses 20-23 serve as guides for the pins 16 to 19 and allow one Relative displacement of the hold-down plate 2 with respect to the Base plate 3 in the x direction.

Thus there is one for both directions of movement x and y positive coupling of the hold-down plate 2 in connection with the clamping element 4 on the base plate 3, the Directions of movement (x and y) are decoupled from each other.

The recesses 20-23 are each multiple here, so that the pin optionally in one of the recesses Group can be used, which is another step adjustment in the y direction results.

As can best be seen from Fig. 1, the base plate 1 a circular opening 24, on the edge of a toothing 25 is attached. The hold-down plate 2 has a vertical collar protruding from the surface of the snowboard S. 26, which engages in the recess 24. She has further a counter toothing 27 in the toothing 25 of the base plate 1 engages and adjacent to the counter teeth 27 another protruding edge 28, which is the top overlaps the base plate 1. The length of the federal government is 26 chosen so that the front of the federal government even when fixed Binding still a distance to the surface of the snowboard S has. If the clamping lever 6 is in the release position, it can the hold-down plate 2 can be raised slightly so that the teeth 25 and 27 are free from each other. The base plate 1 can then about the z-axis in the direction of the arrow c of Fig. 2 are rotated. The toothing is preferred 25, 27 chosen so that the teeth are shorter than that of Teeth 14, 15 or the pin 16 to 19 in connection with the recesses 20-23. This ensures that in a first release position of the pivot lever 6, the hold-down plate 2 are lifted as far from the base plate 1 can that the base plate 1 rotate about the z-axis lets, while still an interference between the Gears 14, 15 or the positive connection 16-19 with 20-23 and therefore no shift in the x or y direction. This is also the rotary setting the base plate from the other two setting options decoupled in x and y direction.

Similarly, the teeth 14, 15 can be designed so that the height of the teeth is less than the height of the Pin 16-19, so that in a further release position of the Swivel lever 6 an adjustment transverse to the longitudinal direction teeth 14, 15, i.e. is possible in the x direction, the peg 16-19, however, continues to engage the recesses Stay 20-23.

From Fig. 1 it can still be seen that hold-down plate 2 has a recess 29 in the area of the tensioning lever 6, so that the clamping lever 6 is at least partially sunk can be.

In Fig. 3, the clamping element 4 (Fig. 3a to 3c), the Base plate 3 (Fig. 3d to 3f) and the hold-down plate 2 (Fig. 3g to 3i) each in three views, namely from the bottom, shown in cross-section and from the top. From FIGS. 3a and 3c it can be seen that the Clamping element 4 in the illustrated embodiment four Has arms 30, 31, 32 and 33 which are perpendicular to each other stand and wear the teeth 14 on their top. The length of the arms 30-33 is the size of the recess 10 of the base plate 3 adjusted so that in all possible Limit positions, in which the pin 5 on the wall the recess 10 is still over all four arms 30-33 the recess 10 of the base plate protrude so that the arms are always covered by the base plate and thus are held.

As can best be seen from Fig. 3c, the Tooth 14 in a uniform direction over the Arms 30 to 33. In the illustrated embodiment runs the toothing 14 thus parallel to the longitudinal direction of the Arms 30 and 32 and perpendicular to the longitudinal direction of the arms 31 and 33.

3f, the tensioning element 4 is in dashed lines drawn in a border position. From this it can be seen that the arms engage between adjacent bases 8, so that you have the largest possible displacement for the clamping element 4 receives.

In the configuration shown in Fig. 3 with four Sockets 8, the clamping element 4 has four arms. Another one Configuration of pedestals is corresponding to the number of arms adapt. For example, if three bases are used, that lie at the tips of an equilateral triangle, so the clamping element 4 has only three arms, which then in one Stand at an angle of 120 ° to each other. It goes without saying Even with such a configuration, the toothing 14 to be distributed over the arms in a uniform direction.

From Fig. 3f it can also be seen that the Top of the base plate 3 protruding pins 16 to 19 in the top view of FIG. 3f opposite the bases 8 are arranged offset by 45 °. It is further from the Fig. 3d and 3f to see that the base plate 3 in plan view can also be circular, in contrast to the embodiment 2, where the base plate 3 is square is. It is desirable to move in one direction to make (x or y) larger than the other direction, so the base plate 3 and the recess 10 can also be rectangular then be the side length in one direction is larger than in the other direction.

As can best be seen from FIG. 3g, the hold-down plate has 2 at their bottom a total of four groups of three slot-like recesses, each are parallel to each other. This is for the recesses 21 is illustrated by the three reference symbols 21a, 21b and 21c. In the illustrated embodiment, the Pin 17 in one of these three recesses, the remaining pins 16, 18 and 19 in the corresponding recesses 20, 22 and 23 intervene. Of course it is Outer diameter of the base plate 3 is smaller than the inner diameter of the projecting collar 26 of the hold-down plate 2, so that the base plate 3 in all possible positions is still within this covenant 26.

At this point it should be noted that between the Top of the base plate 3 and the bottom of the hold-down plate 2 a positive connection is provided is, the training with pin 16-19 and associated Recesses 20-23 only one possible embodiment is. Here too, for example, a toothing would be possible to be provided analogously to the toothing 14, 15.

Fig. 4 shows, similar to Fig. 2, an exploded view of the essential parts of the snowboard binding, however without the base plate. The embodiment of Fig. 4 differs from that of FIG. 2 by the type of Toothing. At the top of the clamping plate 4 is here a toothing 14 'with regularly arranged pyramid-shaped Teeth attached. The teeth are in the x and y directions arranged at regular intervals. On the bottom corresponding recesses are provided in the base plate 3, into which the teeth of the toothing 14 'engage.

In a corresponding way is on the top of the base plate 3 a set of teeth 34 with pyramidal teeth, which are also regularly aligned in the x and y directions and are spaced. The bottom of the hold-down plate 2 then also has pyramid-shaped recesses accordingly teeth 34.

It is clear that one of the two teeth 14 or 34 can be omitted because the hold-down plate 2 and the clamping plate 4 over the pin 5 and the opening 11 are rigidly coupled in the x and y directions. So is in a preferred embodiment, the teeth 14 ' omitted on the clamping plate 4, so that the arms of one have a smooth, flat surface and the underside of the base plate 3 is also smooth and level. Otherwise corresponds 4 that of FIG. 2.
