Description

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

Snowboard bindings are known and exist in their usual form today a front binding element and a rear binding element, from which the front binding element forms a bow from a spring wire in the the boot used (hard boot) with a protruding part of the front end his boot sole is insertable. The rear binding element also exists from an elastically deformable spring wire bracket. On this is a tension or Above-dead-center lever provided for pivoting, when the boot is fixed in the binding this on a part of the sole of the boot protruding from the heel or heel area reaches behind and thereby fixes the boot in the binding. The disadvantage of this Known snowboard binding, among other things, that they are closed only with great effort and can be opened, which is particularly disadvantageous because Use of lifts for safety reasons at least one of the two bindings on Snowboard must be opened. The boot is also attached to the snowboard not optimal with this known snowboard binding, which in particular applies to the lateral fixation of the boot in the heel or heel area. Despite high clamping forces, there is the possibility of a resilient lateral Evasion, through which an optimal control of the snowboard is not possible.

In ski bindings, two jaws are known as the rear binding element provide (WO 80/00063), the space between them for receiving a boot and form lateral contact surfaces for the boot. There is one in each cheek slit-shaped recess is provided, which is provided on the ski boot and laterally pin protruding from the boot is insertable. The recess is at one for this with the binding of the upper side of the ski facing away open. Furthermore, the Recess an oblique course such that de boots after its insertion in the Binding by a front binding element with the pin in the recesses are secured against slipping out. This known binding is a pure ski binding.

A ski binding is known (EP 0 343 302 A1) in which both a front and a rear binding element two the ski boots between them forms receiving jaws and on both jaws of each binding element a recess is provided for receiving a projection on the ski boot. One of the two binding elements is about an axis transverse to the longitudinal axis of the ski and parallel to the Tread of the ski pivoted so that in an open position of the binding concerned ski boots with its projections in the recesses of the cheeks is insertable and then by pivoting the front binding element in a Closed position all four protrusions on the boot in the recesses of the cheeks are held. This known binding is also a pure one Ski binding.

The object of the invention is to demonstrate a snowboard binding which has the disadvantages known snowboard bindings avoided and with simple and easy Handling a reliable fixation of the boot in the binding and thus on Snowboard guaranteed.

To achieve this object is a binding according to claim 1 educated.

The snowboard binding according to the invention is simple and comfortable to put on or getting into the binding possible that the respective boot with the at least one projection in the slot-shaped recess of the rear Binding element inserted and then in this recess by the Baking the binding element provided locking element is locked. The Fixing the boot in the binding is done without tightening the boot feathers on the snowboard and in particular without great effort. It is also possible to release the boot from the binding without exerting any force.

Forces acting transversely to the longitudinal axis of the boot are caused by the jaws formed support surfaces with corresponding counter surfaces on the boot interact, recorded in a controlled manner. These support surfaces are, for example Areas of the at least one recess and / or areas of the jaws of the Binding element outside the recess. The counter surfaces are then either Surfaces of the at least one projection and / or surfaces of the boot.

In a preferred embodiment of the invention Heel or heel area of the boot on each lengthways each side of the boot has a projection formed, which is then transverse with its longitudinal extent or is perpendicular to the boot axis. With this training is then also a direct transmission from around the boot axis acting leverage or torque between Boots and snowboard possible, as they (torques) when Edge of the snowboard occurs. This will create a direct edge control with simultaneous mobility in Direction of travel reached.

Especially when the front binding element in the binding system according to the invention also from a resilient Bracket is formed, a clamping in the invention of the boot between the front and the back Binding element always with the same and in particular also achieved with optimal strength, so that an unwanted Release of the boot from the binding by the driving dynamics is prevented.

Developments of the invention are the subject of the dependent claims.

In the figures, 1 is a boot in the form of a special one Ski or snowboard boots in the area of its sole 2 at least on the front of the boot one of a binding element engaging edge or level 3 forms like this is also common with ski boots.

On the heel 4, the boot 1 has two projections 5, from each of which has a lengthwise direction of the boot Projecting side of paragraph 4. In the illustrated embodiment the projections 5 are axially transverse to one another arranged to the longitudinal axis of the boot and of a length of one penetrating the boot 1 in the area of paragraph 4 Round rod made of a heavy-duty material, preferably made of stainless steel.

As FIGS. 1 and 2 show, the binding 6 consists of essentially from a base plate 7 with its underside at the top of the snowboard, not shown can be attached, on the top two binding elements are attached, namely the front binding element 8, which from a attached to the top of the base plate 7 Plate 10 with a bracket 11, as well as that rear bracket element 9. At least one of the two Bracket elements 8 and 9 is in the longitudinal direction of the base plate 7 adjustable to bind 6 to different shoe sizes to be able to adjust. When fixed in the binding 6 Boot 1 is this by means of level 3 on the bracket 11 held and lies with the bottom of his sole 2 in Area of the front of the boot on the opposite of the front of the boot plate 10 set backwards. Through this Training of the front binding element 8 are all Parts of binding with boot 1 fixed in binding 6 based on the front end of the boot backwards offset so that the binding 6 has a short length.

The rear binding element 9 forms independently of one different design in detail two side Support jaws 13, between which a surface 12 is provided and that between them is fixed in the binding 6 Pick up boots 1 in the area of paragraph 4, i.e. at her vertical support surfaces 14 facing each other for the sides of the Form paragraph 4. The surface 12 is in the binding 6 arranged boot 1 at a distance from the bottom of the Sole 2 or paragraph 4 and is also sloping roof or wedge-shaped, so that any on the Underside of the clump of sticky snow when inserted of the boot 1 in the binding through the sloping roof Surface 12 is blown off.

Each support jaw 13 also has one on the Support surface 14 and on the base plate 7 facing away Top of the support jaw open slot 15, in the to Fixing the boot 1 in the binding 6 has a projection 5 is insertable. Through a later described one Locking element 16 having binding mechanism or Locking device is each projection 5 in the associated slot 15 lockable.

To insert the respective projection 5 into the associated one To facilitate slot 15 is the top of each Support jaw 13 at least in a partial area as an inclined surface 17 formed from the binding element 8 distal end of the binding element 9 or of the support jaw 13 running obliquely downwards in the each slot 15 opens. A similar sloping surface 18 is also formed on the other side of the slot 15.

Furthermore, it is inclined, each slot 15 and obliquely formed such that the longitudinal extension of said slot lies in a plane E, which includes with the plane of the base plate 7 an angle kleinr than 90 ^o, which opens to the the binding element 8 facing away side .

To fix the boot 1 in the binding 6, this is first with its front end in the bracket 11 of the Binding element 8 introduced. The bond is like this set that after this insertion, the projections 5 each at the top of the slot 15, i.e. about on Transition from the inclined surface 17 are in this slot. Then press down the boot 1 on the heel each projection 15 is inserted into the associated slot 15. Due to the inclination of the slots 15 described above required tightening of the boot 1 in the binding in such a way achieved that the bracket forming an angled bracket level 11 is slightly elastically deformed and therefore in particular reliably engages behind level 3.

The binding 6 allows easy connection of the snowboard with the boot 1 without excessive exertion. Since the two binding elements 8 and 9 rigid or at least in are essentially rigidly attached to the base plate 7 also a rigid, optimal guidance of the snowboard Guaranteed fixing of the boot 1 on the snowboard.

The rear binding element 9 can be different configured and also different on the base plate 7 be attached.

Figures 5 and 6 show a possible embodiment Binding element 9a, in which the two, each as a housing trained section jaws 13 via two steel brackets or bracket-like connectors 19 connected together and spaced from each other, which is also the horizontal surface 12 form. With the connecting pieces 19 is the binding element 9a, for example, screwed directly onto the base plate 7.

6 shows in detail the elements of the locking device, the in each housing-like support jaws 13th are accommodated. The locking device exists first from the hook-shaped locking element 16, which at one end below surface 12 on a shaft 20 and is pivotable relative to this, the extends between the two support jaws 13 and in this is pivotally mounted at both ends. The wave 20 is located below surface 12. The axis of shaft 20 lies in the common plane E with the longitudinal extent the slots 15 or their central axes.

At the upper end, each locking element 16 forms one hook-shaped section 21, when pivoting the locking element 16 around the axis of the shaft 22 from one in which Fig. 6 shown with broken lines non-locking Position in which the locking element 16 or the section 21 outside the slot 15 and laterally from this is arranged, pivotable into a position in which the locking element 16 with the hook-like section 21 extends into the respective slot 15, namely in Area of the upper end of this slot and thus one in Slit 15 arranged projection 5 engages behind and thus locked against moving out of the slot 15. Through the above-described arrangement of the axis of the shaft 20 in the plane E act forces through the projection 5 in the sense of a Moving this projection out of the slot 15 on the Act locking element 16, not in the sense of a Releasing the locking or swiveling the Locking element 16 in the unlocked position. By Spring elements, not shown, for example a Leaf spring, each locking element 16, which is in the unlocking position on the binding element 8 facing side of the slot 15 is located in the locking Prestressed position.

The locking device further comprises one by one Axis parallel to the axis of the shaft 20 pivotable locking lever 22, in the locking position of the locking element 16 against one on this locking element Formed surface rests and thereby an undesirable Swiveling the locking element 16 from the locking position prevented. On the shaft 20 rotatably provided a driver 23, one with the Locking lever 22 cooperating control surface 24 and one with a stop 25 on the locking element 16 cooperating counter surface 26 forms. One over one Support jaws 13 projecting end is on the shaft 20 Actuating lever 27 is provided. By panning this Actuating lever and thus the shaft 20 can in the locking position locking element 16 be solved. This will initially go through the control surface 24 of the locking lever 22 is pivoted so that it is the locking element 16 releases. When panning the Driver 23, the counter surface 26 comes against the stop 25 to the system, which then the locking element 16 against carried the effect of the spring, not shown, and in the unlocking position is pivoted. A ratchet lever 28 engages behind a surface of the in the unlocking position located locking element 16 and holds this in the non-locking position. The pawl lever 28 has an approach 29 which projects into the respective slot 15. For the locking lever 22 and for the pawl lever 28 are spring elements, also not shown, are provided the locking lever in a locking element 16 in the locking position securing position and the Pawl lever 28 in a locking element 16 in the Preload the non-locking position.

Figures 11-13 show the function of the elements of the Locking device. 11 is the insertion a projection 5 in a slot 15 when unlocking Locking element 16 shown. The lead comes 5 against approach 29 to the system, so by pivoting the Ratchet lever 28 released the locking element 16, which then locks into that shown in FIG Pivots position in which the locking element 16 also is secured by the locking lever 22.

13 shows the state of the locking device when unlocking using the operating lever 27, wherein in this figure, the locking lever 22, the locking element 16 has already released and the driver 23 against the Stop 25 is present.

In the embodiment shown in FIGS. 7-10 the binding element 9a is not absolutely rigid, but with a certain possibility of movement on the base plate 7 attached. For this, an intermediate or mounting plate 30 used, on one surface side two plate-shaped bearing elements 31 are provided, of which each has a trunnion or mandrel 32 which is in an opening 33 engages in the connector 19th is provided between the two support jaws 13. The Openings 33 with their axis parallel to the longitudinal extent the base plate 7 have a cross section, which is larger than the cross section of the mandrels 32. Between the intermediate plate 30 and the underside of the connecting element 19 is a rubber buffer 34 is arranged due to elastic deformation a certain movement of the Allows binding element 9a relative to the base plate, namely by an amount equal to 32 through the play of the mandrels Openings 33 is predetermined.

FIGS. 14 and 15 show a preferred embodiment a binding element 9b, which in turn consists of the two housing-like support jaws 13, each with a slot 15 consists. Instead of the locking element 16 is a Locking element 16a provided. The two locking elements 16a, which in this embodiment is rotation-proof are held on the shaft 20, are each by a leaf spring 35 is biased into the locking position, in which each locking element 16a with its hook-like Section 21a from the housing-like support jaws 13 on the The top protrudes and outside the support jaw 13 den concerned slot 15 at its upper, open end closes and thereby one sitting in the slot 15 Latch 5 locked. Furthermore, each locking element 16a designed so that when pivoting against the Effect of the spring 35 in the non-locking position in this position with the hook-like section 21a on the Binding element 8 facing away from the slot 15.

At the free end of the hook-shaped section 21a, each locking element 16a forms an inclined surface 36, which lies in a plane running parallel to the axis of the shaft 20, which includes an angle of less than 90 ^° with the base plate 7, which is to the rear, ie to the opens the side of the binding element 9b facing away from the binding element 8. To fix the boot 1 in this binding 6a, the front end of the boot 1 is first inserted into the bracket 11 of the binding element 8. The boot 1 is then moved with its heel 4 downward, the projections 5 moving approximately in a circular arc around the front end of the bracket 11 and each projection coming to bear against an inclined surface 36. Upon further downward movement of the heel area of the boot 1, the projections 5 are inserted into the respective slot 15 with resilient evasion of the locking elements 16a, so that finally each locking element 16a pivots back into the locking position by the action of the leaf spring 35 and thereby this projection 5 in the associated slot 15 locked.

The axis of the shaft 20 also lies in the binding element 9a and the longitudinal extent of each slot 15 in the plane E, which has the unwritten tendency. To open the Binding, the two locking elements 16a over the Actuating lever 27 and the shaft 20 in the unlocking Position swiveled.

The binding 6a and its binding element 9b stand out through an extremely simple and therefore very reliable Construction. There is a multitude of elements in the Locking devices dispensed with. Rather, these are in the essentially on the hook-like locking elements 16a reduced.

The invention has been described above using an exemplary embodiment described. It is understood that changes and modifications are possible without thereby of the invention underlying inventive concept is left.
