Abstract

A snowboard (9) has a clamp plate (1) with a concentric ring (2) to which the ski boot binding (4) is attached. The unsecured ring is free to rotate in azimuth to a selected direction relative to the board. The clamp is associated with a clamp that when operated holds the ring in a fixed direction relative to the board and direction of travel.

Description

I. Field of application

The invention relates to a bond.

II. Technical background

A binding is used to fix one foot of the user - sometimes both at the same time - on a sports equipment such as a snowboard. Without limiting the invention thereof to the exclusive use of the term "sports equipment" for the award of the present application, only the term "board" will be used.

The typical foot position when driving on a snowboard looks so that at least the front in the direction of travel is fixed obliquely to the direction of travel of driving aligned on the board, while the other foot is fixed approximately or perpendicular to the direction of travel on the board.

For the lift with drag lifts or chairlifts, but also for pushing forward on level terrain, the user releases the binding of the rear foot in the direction of travel. For pushing forward in level terrain, he then uses this free rear foot for pushing and pushing forward against the ground.

However, the then very obliquely to the direction of travel front foot in the front binding is uncomfortable and above all prevents far-reaching steps and thus a fast progress.

A common binding unit for attaching a foot on a snowboard is currently usually constructed so that the actual binding is arranged on a rotary ring or integrally formed together with this rotary ring, which can be clamped by means of a fitting in the inner opening of the rotary ring clamping plate on the board, by the clamping plate is screwed onto the board and pressed with its outwardly projecting edge of the underlying inner circumference of the rotary ring in the desired rotational position without play between the clamping plate and board.

So that this connection is not only frictional but also positive fit, is arranged on the underside of the protruding edge of the clamping plate on the one hand and the other hand directed upwardly facing annular shoulder of the rotary ring on the other hand partially or over the entire circumference circumferentially a matching toothing whose teeth at the board abutting clamping plate engage one another positively.

To adjust the inclination of the binding relative to the direction of travel thus the screw of the clamping plate on the board must be solved so far that the clamping plate can be raised so far until the teeth against the rotary ring disengaged, and then bring the rotary ring in the desired rotational position , and in this rotational position to screw the clamping plate against the board again.

III. Presentation of the invention a) Technical task

It is therefore the object of the invention to provide a binding unit in which at least the binding unit of the front foot in the direction of travel quickly and easily allows rotation of the foot in the direction of travel and in particular the locking of the binding unit in this direction, without the foot completely out of the To be bound.

b) Solution of the task

This object is solved by claim 1. Advantageous embodiments will be apparent from the dependent claims.

Rapidly changing the inclination of the bond, e.g. Aligning in the direction of travel of the board for the lift driving, etc., is possible by the rotating ring to which the binding is connected, even then relative to the clamping plate is rotatable when this clamping plate is firmly bolted to the board.

Thus, in the inclination, so the normal position of the binding to the direction of travel, the foot is securely held in this oblique position, a locking device between the rotary ring and the adjoining component is provided to lock the rotary ring at least in this normal inclination safe and preferably form-fitting manner to let.

Preferably, there is at least one further detent position for the longitudinal orientation of the binding in the direction of travel, and optionally for further functional positions.

The adjoining component may be directly the clamping plate, or else a further component arranged between the rotating ring and the clamping plate, such as an adjusting ring, which, however, is then non-rotatably coupled to the clamping plate when the clamping plate is firmly screwed onto the board.

Theoretically, such snowboard bindings, which consist of turning ring and clamping plate in the basic version, can also be constructed the other way around by the ring is firmly bolted to the board and serves as a clamping ring, and a recorded in its interior rotary plate firmly presses against the board, which actual bond carries. However, this design is unusual today, but can also be based on the present invention. For the following details, however, only described for the aforementioned common shape of the clamping plate and the clamping plate outside rotating rings are described.

On the one hand, the latching device has a latching lug which is movably arranged either on the rotary ring or on the opposing, adjacent component in order to engage in a corresponding catch recess or to disengage from this receptacle.

Actuates the locking lug by means of a lever which is operatively connected to the latching lug and preferably protrudes outwardly from the rotary ring and is biased by a spring in the latching position. The lever is best stored by means of a horizontal pivot axis so in the rotary ring that he brings the locking lug out of engagement of the detent recess by the lever is pressed down. In addition, when the inventive construction is arranged on the front in the direction of travel binding unit, and the lever is disposed at a position of the circumference, in the direction of the rear binding unit, ie rearward or obliquely behind, projecting, this lever by means of the rear foot in the direction of travel be depressed by the user who has to be solved from the rear binding unit anyway for lifting or managing level sliding distances.

Also, any other actuator may be selected, such as a handle that must be pulled radially outward to disengage the latch.

If the binding unit substantially consists, as mentioned, only of turning ring and clamping plate, the locking receptacles are formed directly in the clamping plate.

A fine adjustment of the angle of inclination for normal driving - as in today's snowboard bindings usual - is no longer given, since both the inclination and the longitudinal position are fixed by the position of the two locking mounts.

If the possibility of such a fine adjustment continues to be obtained, several solutions are conceivable.

One possibility is not to form the locking receptacle for receiving the latching lug of the rotary ring in the outer periphery of the clamping plate, but a concentric adjusting ring arranged between clamping plate and rotary ring. This setting is - like the rotary ring in today's usual snowboard bindings - held by the central clamping plate on the board, and firmly fixed on the board screwed clamp plate rotatably between the clamping plate and board, for example, again by means of positive locking generating axial teeth between the two parts and in the radial Direction of overlapping shoulders of clamping plate and adjusting ring.

The adjusting ring in turn holds on its outer circumference the rotary ring with the binding on the board, for example, in turn, by means of a shoulder lying on the inner circumference of the rotary ring, the radial projecting edge on the outer circumference of the adjusting ring. However, this connection is not carried out by clamping, so that the rotary ring is rotatable relative to the adjusting ring, provided that the locking device which is formed between the rotary ring and adjusting ring is not engaged in one of the locking receptacles.

This makes it possible, by loosening the screw of the clamping plate to adjust the adjustment ring in such a rotational position that the formed in the adjusting locking recess for the inclination, so the normal driving position, the desired angular position of the binding to the direction of travel, ie the longitudinal direction of the board results. In this position, the clamping plate is screwed firmly on the board and thus fixed the adjusting ring in its rotational position.

Although this also the locking receptacle in the adjustment ring for the longitudinal position of the bond is changed, but it is at such a fine adjustment only corrections of a maximum of ± 10 °, then the orientation of the bond deviates from the exact longitudinal direction of the board, which the intended use of straightening the binding for pushing by the other foot is not significant with far-reaching steps and similar functions.

Another possibility is to remain with the basic design with only two functional parts (rotary ring and clamping plate) in a connection unit, and thereby to change the position of the effective locking receptacles in the clamping plate can:

This is possible in a simple manner, for example, in that along the circumference of the clamping plate, a plurality of locking receptacles are arranged behind one another and as closely as possible following one another. The user then most of these locking receptacles are disabled by sealing plugs, and only the required locking receptacles, namely usually only two, namely for the inclination and for the straight position, left open.

For this purpose, the locking receptacles may be open, for example, to the top of the clamping plate in order to introduce the sealing plug from the top can. In order to prevent these sealing plugs from pressing radially outward against the inner circumference of the rotary ring and grinding it, the cross section of the locking receptacles visible from above and also the sealing plug can be formed.

The goal here is that by closed by means of sealing plugs snap receptacles a smooth in the circumferential direction, as far as possible without heels Peripheral surface is formed in order to cause no resistance during the sliding along the biased by spring force in the closed position locking lug on this peripheral surface during rotation of the rotary ring, such as the engagement of the latching lug on the open, activated latching receptacles.

1a shows the top view of a snowboard on which two binding units are arranged in the usual way in the direction of travel so that both the front in the direction of travel and the rear in the direction of travel binding unit a specific inclination relative to the direction of travel, the longitudinal direction of the board 9, taking. The rear binding unit is like this illustrated how the most commonly used binding units are constructed, namely consisting of a rotary ring 2, the outer periphery is extended to an elongated shape, corresponding to the shape of a shoe sole, and on which the actual binding 4 is arranged in the form of stops and tensioning straps, the fixed the user's shoe on this rotary ring 2.

In the inner, circular opening 2b of the rotary ring 2, the clamping plate 1 is added, which - similar to the sectional view of Fig. 1 b to recognize - holds the rotary ring 2 on the board 9 by an outwardly projecting, circumferential edge 1a of the clamping plate extends above an underlying shoulder of the rotary ring 2 in the radial direction outward.

As a result, the rotary ring 2 is centered on the one hand with respect to the vertical axis 11 and on the other hand corresponds to the height distance of the edge 1a relative to the board 9 of the thickness of the shoulder 2a, so that the rotary ring 2 is clamped relative to the board 9, if the clamping plate 1 firmly on the board. 9 is screwed by means of screws which extend through arranged in the clamping plate 1 slots 8 therethrough.

The elongated holes 8 extend either in the longitudinal direction of the board or circular segment around the center of the press plate 1 around, so that when loosening the screw connection either a displacement of the clamping plate 1 in the longitudinal direction or a rotation of the clamping plate about the vertical axis is possible.

The front binding unit according to the invention, such as e.g. 1, this differs from the fact that the rotary ring 2 remains rotatable around the clamping plate 1 even when the clamping plate 1 is screwed firmly to the board 9, ie the shoulder 2a of the rotary ring is not jammed between the clamping plate 1 and the board 9.

To allow the rotation, the top of the rotary ring 2 is also slightly higher than the top of the screwed clamping plate 1, to rotate through a fastened on the rotary ring 2 by means of the binding 4 shoe not to hinder by the shoe brine on top of the clamping plate 1 grinds.

As shown in FIG. 1b, a latching device 3 is arranged in the rotary ring 2, in the form of a pivotable lever 6 which is mounted about a horizontal pivot axis 15 in the rotary ring 1 and the actuating lever 6 protrudes outwardly from the rotary ring 2, while the latch 5 acting other end of the lever can protrude into the region of the clamping plate 1 when the lever 6 is in an approximately horizontal position. For the locking lug 5 for this purpose at least one locking receptacle 7 is provided in the outer periphery of the clamping plate 1, and a spring 14 biases the latching lug 5 in the latching position.
A rotation of the rotary ring 2 is therefore only possible if the lever 6 is acted upon in the deactivated position 6 of the latching lug 5 and the latching lug 5 is outside the latching receptacle 7.

As soon as the lever 6 is released and the latching lug 5 passes into the region of a latching recess by rotation of the rotary ring 6, the latching lug 5 engages in the latching receptacle 7, acted upon by the force of the spring 14, and the rotary ring 2 is fixed against rotation relative to the clamping plate 1 1, or in the dashed longitudinal position shown in Fig. 1, in which, however, not necessarily also a locking receptacle must be present, but preferably also must be present.

In order to prevent indirect rotation of the shoe sole on the upper side of the clamping plate 1 by means of ice adhering to the shoe sole during rotation of the rotary ring 2, the rotary ring 2 can also act as a bearing surface for the shoe, firmly connected to the rotary ring 2, via the clamping plate 1 have continuous cover plate 17 which is screwed along the circumference, for example with the rotary ring 2.

Fig. 2 shows the analogous reverse solution with a clamping ring 2 ', which is not rotatably screwed relative to the board 9 and holds a recorded in its inner opening rotary plate 1 positively, but rotatably on the board, in which case the bond 4 on the rotary plate. 1 'is attached. The latching device, for example, in turn, constructed as explained with reference to FIG. 1b, is then received in the clamping ring 2 '.

Fig. 3a and 3b show a further design, which is constructed in terms of firmly screwed central clamping plate 1 and the externally rotatable, but captive rotary ring 2 analogous to the solution of Fig. 1 b.

However, there is radially concentric circumferentially between the clamping plate 1 and the rotary ring 2, an adjustment 12, with the help of a fine adjustment of the angular position of the binding can be done in the skew, as in today's usual snowboard bindings.

For this purpose, the one or more locking receptacles 7 are arranged for the accommodated in the rotary ring locking device 3 in the outer periphery of the adjusting ring 12.

Just as the adjusting ring with its outer circumference radially overlaps the rotary ring 2, its inner circumference is overlapped by the upper edge 1a of the clamping plate 1, but with the difference that here the dimensioning is chosen so that when firmly screwed on the board clamping plate 1 of the adjustment 12th in a certain rotational position also firmly clamped against the board 9, which is supported by the positive connection of a toothing 16, preferably on the underside of the edge 1a of the clamping plate 1 and the top of the shoulder 12a of the adjusting ring 12.

The user thus turns the rotational position of the adjusting ring 12 - after loosening the screw of the clamping plate 1 until the toothing 16 is disengaged - so that after locking the locking device in the corresponding receptacle 7, the bond 4 in the desired skew angle to Direction of travel 10 is located, and screwed the clamping plate 1 and thus also the adjusting ring 12 in this position.

If the outer circumference of the adjusting ring 12 is arranged stationary, thus the latching positions of the rotary ring 2 and thus the bond 4 are predetermined.

Fig. 3b shows in plan an additional way how this positioning can be changed.

For this purpose, a plurality of locking receptacles 7 are arranged as closely as possible along the circumference, most of them, however, closed and deactivated by sealing plugs 13, so that the latching lug 5 can not penetrate into these closed latching receptacles 7. Only e.g. two locking receptacles 7a, 7b are - left open for the inclination and the longitudinal position of the binding relative to the board and thus can be solved by pressing the lever 6 from its rotational position and thus rotated in the other rotational position of the user's front foot in the direction of travel.

The possibility of a large number of locking receptacles, which are closed again by closing plugs except for the few active locking receptacles, can of course also be used in the two-part design of FIG. 1 b in the outer periphery of the clamping plate.

Figures 4 and 5 show a preferred embodiment which combines the basic possibilities of several previously described solutions in itself.

In FIG. 4a, such a single binding unit is shown locked on a board 9 in the straight ahead position and in FIG. 4b in the normal inclined position.

This is possible here by two plates 1 and 1 'are arranged one above the other, wherein the lower, the clamping plate 1, is screwed tightly to the board 9, while the upper, the rotary plate 1 ', on which the binding 4 is screwed in a fixed rotational position, relative to the lower clamping plate 1 rotatable and in two latching positions corresponding to the two driving positions can be shut down. This is done with the help of the deactivatable locking pin 5, which is biased by spring force into the latching position and must be pulled to deactivate by hand up, whereupon the rotary plate 1 'together with binding 4 and the user's foot attached to the board 9 can be rotated , In particular, until the released latching pin 5 'in the desired recess (not visible in Figures 4) engages.

In this case, the rotary plate 1 'is rotatably mounted twice relative to the clamping plate 1:

On the one hand on the outer periphery, by the outer edge of the basically circular rotary plate 1 'is held in an upwardly inwardly bulging 1b of the lower clamping plate 1, which, however, is only present on two opposing circular segments.

In the upper turntable 1 'seen in plan view deviating from the circular shape has two opposing flats 1'a, for assembly in alignment of these flats 1'a on the bulges 1 b, the rotary plate 1' from above placed on the clamping plate 1 and then secured by twisting positively in this.

In addition, there is a second bearing on the inner circumference, where the rotary plate 1 'has a central recess 1'b with a radially inwardly facing annular shoulder 1'c.

By screwing a support plate 18, which fits into the recess 1'b and is seated on the shoulder 1'c, through the recess 18 against the clamping plate 1 underneath, the rotary plate 1 'on the inner circumference of this recess 18 by means of the shoulder 1'c additionally mounted relative to the support plate 18 and thus the clamping plate 1.

Thus, the user in addition to the two locking positions of the locking pin 5, the position of his foot and thus the binding 4 detail against the rotary plate 1 'and thus set the board 9, the bond 4 is not directly on the rotary plate 1' screwed, but is with Help a Einstellringes 12 'on the rotary plate 1' jammed. The round outer circumference adjustment ring is seated in a corresponding circular recess of the bottom plate of the binding 4, which has a radially inwardly facing annular peripheral shoulder, which is clamped by the adjusting ring 12 'down against the rotary plate 1'.

To prevent the unintentional twisting, the outer circumference of the adjusting ring 12 'and the inner circumference of the corresponding recess in the bottom plate of the binding 4 may have a splined profile 19.

In addition, the adjusting ring 12 'is not screwed over simple screw holes relative to the rotary plate 1', but via mutually parallel slots, so that in addition to the rotation and a longitudinal displacement of the adjusting ring and thus the bond 4 on the rotary plate 1 'in the assembly as desired possible is.
