Description: The present invention relates to a snowboard binding according to claim 1. Such bindings are also referred to as " soft binding " or " tray binding " because they are intended to be used with relatively soft snowboard shoes and have a high level of flexibility, such as that provided by so-called " freestyle riders " it is asked for. In contrast, the present invention does not relate to so-called "hard bindings" in which a relatively hard ski boot or a ski boot-like snowboard boot is fixed by engaging projections or recesses on or in the hard sole of the boot in the binding.

The binding of the invention is used to fix a snowboard boot on a snowboard. It is designed as a so-called rear entry binding and includes a leg rest, which can be pivoted between a rear entry position in which a shoe can be particularly easily inserted from back to front into the snowboard binding or in the opposite direction out of the binding, and a forward driving position is articulated. In this manner known per se a very comfortable entry and exit is made possible in or out of the binding.

The usual in such snowboard bindings leg rest, also called "highback". or " rear spoiler " is used to support the back of the snowboard boot or the fibula of a snowboarder to the rear. In this case, the leg support is pivotally mounted about an axis oriented transversely to the longitudinal direction of the base plate, in order to be able to set a specific angle of inclination, which defines the so-called template of the lower leg of a snowboarder. The inclination angle of the legrest can usually be adjusted for the driver's desired driving position.

In the driving position, the legrest is fixed by a suitable locking device. To get out of the snowboard binding, the locking device is released, so that the legrest folded back back into the open position or entry position and the shoe can be pulled out of the binding.

Furthermore, the pivotability also serves that the legrest, which protrudes in practice in normal driving position about 20 to 30 cm from the snowboard surface, can be folded forward on the surface of the snowboard, so that they during transport and storage of Snowboards less disturbing.

Furthermore, the binding according to the invention comprises a toe element, by which a front portion of an inserted into the snowboard binding shoe is at least partially embraced from the front so that he held forward and further movement of the shoe forward is not possible. Both the leg support and the toe element can be fastened either directly or via further elements indirectly on the surface of a snowboard.

In previously known bindings conventionally an instep element is provided, which is also required for fixing a shoe in the binding. The positioning of the shoe in the longitudinal direction is effected by the tensioning of the instep element. The instep element thus simultaneously fulfills two functions, on the one hand ensuring the grip of the shoe in the longitudinal direction forward and on the other hand also the hold of the shoe upwards. For this purpose, the instep elements are usually stretched obliquely backwards and downwards, which is associated with the disadvantage that a significant pressure in the shoe is often felt by the snowboarder. Further, a toe member is also usually provided, which is stretched around the front portion of the shoe to hold it down in the binding. Also, this is often perceived as unpleasant pressure in the shoe for the snowboarder. 1/10 östeiiÄsdtC !! Even with snowboard bindings with simplified handling by rear entry and zurückklappbarer legrest a relatively strong pressure on the instep element is exerted when closing or when folding the legrest, which also here both the stop in the longitudinal direction and must ensure the hold up. Thus, it is known, for example, from DE 44 35 113 C1, to steer the legrest such that it can be pivoted to the rear into a folded-down entry position, in which a snowboard boot can be inserted from the rear into the snowboard binding when the instep element is fixed. After inserting the snowboard shoe against the instep element, the legrest is folded up until it has assumed a predefined closed position corresponding to a driving position. By folding the legrest of the snowboard boot is pushed even further forward against the instep element, so that while the desired clamping force is applied, but at the same time again perceived by the snowboarder disturbing pressure loads occur, which are also directed in particular down. Furthermore, it is disadvantageous that, at least in the last area, the insertion of the shoe is made considerably more difficult due to the frictional forces occurring here.

From US 5,692,765 A a Heckeinstiegs snowboard binding is known, in which also the legrest is folded back for entry and exit to the rear. In contrast to DE 44 35 113 C1, however, the snowboard shoe is not used here for a fixed instep element, but rather for an extended instep position, here as "instep strap". designated Ristriemen introduced into the snowboard binding. In addition, a second one is called "toe strap". designated toe strap provided which also engages obliquely from above the front of the shoe area in almost parallel orientation to Ristriemen. This toe strap is also expanded to a release position when opening the binding for disembarkation or for insertion of the shoe. Both the instep strap and the toe strap are in each case articulated to the base plate of the binding with only one of their ends, whereas the opposite end of the respective strap is free and has no firm connection to the base plate or to a side cheek formed thereon. Both the instep strap and the toe strap are each coupled by a cable pull with a locking lever hinged to the leg support so that the two straps are widened when the locking lever is opened and the two straps are retracted when the locking lever on the folded leg rest is locked.

A firmly defined end stop, against which the shoe can be tightened by folding and locking the leg support, therefore forms neither the toe strap nor the instep strap. Rather, here the shoe is not only fixed during the locking of the locking lever by the interaction of toe straps, instep strap and legrest, but also be positioned. In this positioning of the shoe, however, a predominantly downwardly acting increased pressure is exerted on the shoe by the two straps, which increasingly makes the positioning with progression of the locking more difficult due to the frictional forces and which in turn can lead to the disturbing pressure loads.

From EP 1 623 745 A1, a snowboard binding embodied as a soft binding is known, which in the closed state fixes a shoe inserted between a legrest which can not be folded back and a front toe element in such a way that the shoe does not move further forward in its longitudinal direction can be. However, the legrest is firmly in a heel strap, which is also referred to as a heel cup. Such heel straps embrace the rear sole region of the snowboard boot or the heel of a snowboarder, wherein the heel strap is rigidly connected to the base plate of the snowboard binding.

This design is associated with the disadvantage that the entry into the binding can only be done from above and is therefore associated with the snowboarder with significantly more effort. The toe element must be brought into a position when entering or even when disembarking, in which it releases the shoe upwards, so that for fixing the shoe in the binding always an additional to be performed clamping operation is required, in the 2/10

& tS !! isCiii $ ChS AT10 672 U1 2009-08-15

Usually by means of an instep element of the aforementioned type and / or as in EP 1 623 745 A1 by means of the toe element is executed. Therefore, such bindings can not provide the comfort of a Heckeinstiegsbindung and especially getting into these bindings designed relatively cumbersome.

Object of the present invention is therefore to provide a structurally simple and inexpensive to produce snowboard binding, which allows a particularly comfortable entry and exit, and avoids the impairments for the snowboarder by pressure loads on an instep element.

This object is achieved by a snowboard binding according to claim 1. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Essential in the solution according to the invention is that the legrest of the Heckeinstiegsbindung can be locked in the forward driving position such that a recorded in the snowboard binding shoe is fixed by the leg rest and toe element in its longitudinal direction relative to the snowboard binding, said Vorschwenken the legrest in the front driving position causes the fixation of the shoe. When swinging the leg rest of the shoe is pushed as far as possible forward against the toe element and so advantageously clamped between the leg rest and the toe element.

A significant advantage of the snowboard binding according to the invention is that both the comfortable Heckeinstiegsmöglichkeit a particularly simple entry into the binding and disembarkation from the bond allowed, as well as the fixation of the shoe in the longitudinal direction by the legrest and the toe element an additional instep element which pushes the shoe back against the leg support is dispensable and thus the associated pressure loads for the driver can be avoided. A suitable instep element is needed at most to keep the shoe down in the binding. The longitudinal compressive forces are transmitted across the sole of the shoe. This results in comparison to conventional strap bindings for the snowboarder a significantly less noticeable pressure in the shoe, which means a considerable increase in comfort and thus represents a decisive advantage. In practice, it has been shown in comparison that a binding according to the invention can be driven considerably more pleasantly and pressure-less than a binding in which the longitudinal positioning of the shoe is achieved only via the leg support and an instep element.

But even if an instep element is provided, which acts on the shoe and the back against the folded legrest, the pressure applied to the shoe here is significantly lower, since a first part of the forces acting backwards, the pressure of Counteract leg rest, already exerted by the toe element and transmitted over the shoe sole. This part of the forces acting backwards thus no longer stresses the instep area.

Another advantage is that the folding up of the legrest over the entire pivoting range can be performed with less effort than is possible with a fixed instep element, which already when closing the binding or when folding the legrest back directed back pressure on the shoe.

The shoe can therefore be easily used in folded back legrest in the open binding, after which the legrest can be folded to close the binding over a much larger path without effort in the driving position, as is possible in bonds with fixed instep element , The Vorschwenken the leg rest in the front driving position then causes the fixed tension of the shoe between the leg rest and the toe element in an advantageous manner. The present invention combines for the first time the advantage of optimum binding performance and good performance without excessive pressure loads for the driver with the advantage of a high level of comfort when getting in or out of the driver Bond that has previously ruled each other out.

In addition, an instep element due to the lower holding forces, which only has to be transferred in the direction of the construction according to the invention in a direction perpendicular to the snowboard surface, are now performed much easier. As a result, the snowboard binding according to the invention can have a lower weight and, above all, can be produced particularly inexpensively.

It is particularly advantageous if the toe element in the longitudinal direction of the binding forms an end stop for a front region of a shoe that can be accommodated in the snowboard binding, which is fixed independently of a pivoting movement of the legrest or is permanently adjustable. In such a fixed end stop adverse pressure loads and increased force are avoided, which can occur in known bonds by taking place during the closing movements of the toe element.

It is also of great advantage if the toe element is fixed transversely relative to the binding and bevelled on the inside and / or concavely curved in order to form with respect to the transverse direction of the binding centering means for a front portion of a recordable in the snowboard binding shoe. Alternatively or additionally, inlet bevels may also be provided for the centering of the front shoe area.

It is particularly favorable in this case, although the legrest is curved concavely on the inside to form with respect to the transverse direction of a centering means for a rear portion of a recordable in the snowboard binding shoe. The shoe is then locked after each closing always in exactly the same position, so that the driver is always the same in the binding and thus always the same on the snowboard, which means a significant advantage in practice.

It is also particularly advantageous if the legrest and the toe element are arranged on a common base plate of the binding. The base plate can be fastened either directly or indirectly via a hold-down plate to be inserted into a round opening on the upper side of a snowboard, in particular by means of screws. The leg support may preferably be articulated to laterally raised walls of the base plate, which are also referred to as side cheeks.

To make getting into the binding and getting out of the binding as comfortable as possible is preferably proposed that the toe element is arranged such that a front portion of a recorded in the snowboard binding shoe also overlapped from above and / or on the sides is. As a result, at least in the front shoe area no further holding and / or clamping elements are required, which would otherwise operate the driver.

It is also particularly advantageous if the legrest can be locked in the front driving position in a Vorneigung that is inclined so that a rear portion of a recorded in the snowboard binding shoe is also held up in the snowboard binding. In this way, no further holding elements are required in the rear shoe area, which would have to actuate the driver in conventional bindings in addition or would affect the comfort when entering due to pressure forces and / or frictional forces in the manner described above.

According to a particularly preferred embodiment of the invention it is proposed that the leg rest and the toe element are arranged such that one in the Snow- 4/10

AT10 672 U1 2009-08-15 shoe binding can only be fixed to the binding by the toe element and the leg rest. Advantageously, while other binding elements for a hold of the shoe down, d. H. against a direction pioneering the snowboard, not required. Only for the lateral support of the shoe sidewalls can be provided if the force exerted by the inside concave design of the leg support and the toe element lateral support of the shoe is not sufficient. As a result, the weight and, above all, the production costs of the binding according to the invention can be considerably reduced.

In an alternative embodiment of the invention, at least one Rist element is additionally provided for fixing a recordable in the snowboard binding shoe, by which an area of an upper side of a recordable in the snowboard binding shoe is overlapped. The fixation of the shoe in the longitudinal direction is still achieved by the clamping between the toe element and leg support, so that the instep element primarily serves the downward holding of the shoe on the base of the binding. In addition, however, the instep element can also perform a complementary holding function to the rear against the legrest with suitable alignment.

In order to facilitate the insertion of the shoe at an additionally provided instep element further, it is particularly advantageous if the instep element between at least one clamping position and at least one release position can be adjusted. An inserted into the binding and already clamped between the leg support and the toe element shoe can then be fixed by adjusting the instep element in its clamping position in addition to the binding.

To further increase the comfort is proposed that the instep element between a clamping position and a release position is adjustable and that control means are provided by the pivotal movement of the legrest in the entry position at least partially with an adjustment of the instep element from the clamping position to the release position is coupled.

According to a particularly preferred embodiment can be provided that the control means are designed such that the pivoting back of the legrest in the entry position effected adjusting movement of the instep is greater than the pivoting of the legrest in the driving position effected adjusting movement of the instep element. When folding up the legrest in the driving position, the instep element is thus at best moved back over a partial area of its adjusting movement when opening the binding. A major advantage of this uneven for the back and Vorschwenken the legrest coupling with the adjustment of the instep element is that the folding up of the legrest over the entire pivoting range with very little effort is particularly easy to carry out, as a back pressure on the instep element by a in the binding used shoe is present at best to a much reduced extent.

It is particularly advantageous if the control means are designed such that they cause a coupling with the adjustment of the instep element only when pivoting back the legrest in the entry position, whereas when Vorschwenken the legrest in the driving position, a coupling with an adjustment of the instep element not given is. By the swiveling of the assistant forwards leads to no adjustment of the instep element at all, so a maximum simplification of the closing process and a maximum reduction of the force required to fold up the legrest force is achieved.

In order to make the entry into the binding and disembarkation from the bond as comfortable as possible, it is proposed that the adjustment of the instep element comprises a pivoting movement and / or an opening movement, which opens the instep element or widens its scope or increases its length. 5/10 östeiiÄsdtC !! It is furthermore particularly advantageous if the instep element comprises at least one buckle which is actuated by the control means in such a way that it causes an opening or an extension of the instep element when the legrest is pivoted back into the entry position , In this way, the control means are not needed on both sides of the binding, but only once per instep element on the buckle. As a result, the weight and, above all, the production costs of the binding according to the invention can be considerably reduced. The buckle and the control means may preferably be designed as described in detail in the priority application DE 10 2007 003 339, to which reference is explicitly made in this regard.

It is particularly advantageous if the instep element is pivotally hinged to the binding, wherein the pivot axis of the instep element is identical to the pivot axis of the legrest. As a result, in a change in position of the leg support for size adjustment of the binding when adapted to a larger or smaller shoe shape automatically also allows an adjustment of the instep element, so that a separate adjustment of the instep element is not required. Another significant advantage consists in the fact that the control means for coupling the control movements, ie the pivoting movements and / or the adjustment movements, can be carried out much simpler by the inventive arrangement of the pivot axes of the legrest and the instep element on a common pivot axis. In particular, this eliminates the need for additional intermediate levers and connecting levers, so that the snowboard binding according to the invention can be made particularly simple and compact and weight-saving and inexpensive.

It is also particularly advantageous if locking means are provided for locking the legrest in the front driving position, which comprise at least one encompassing the leg support traction means which is firmly clamped by a locking lever. The traction means may preferably be formed by a cable attached at its ends in a front or middle region of the binding and externally guided around the leg support. When tightening the cable is subjected to train, with the locking lever operated for this purpose is preferably hinged on the outside of the legrest.

Further advantages and features of the invention will become apparent from the following description and the embodiments illustrated in the drawings. Show it:

Figure 1: Schematic representation of a first invention snowboard binding with additional instep element; and

Figure 2: Schematic representation of a second invention snowboard binding without additional instep element.

The snowboard binding 1 shown in Figures 1 and 2 has a base plate 2 with a central circular opening, which can record a hold-down in a conventional manner for mounting on a snowboard. On the two longitudinal sides of the base plate 2 each provided with recesses side cheek 3 is formed approximately vertically upstanding to the base plate 2, between which a not graphically illustrated snowboard shoe can be recorded and fixed in the snowboard binding 1. The side cheeks 3 serve also a lateral fixation of the snowboard boot.

In the rear upper region of the side cheeks 3, a legrest 4 is articulated pivotably about an axis oriented transversely to the longitudinal direction of the baseplate 2. The leg rest 4 is pivotable between a rear entry position E, which is thinner in the figures and in which a shoe is easily insertable from behind to the front into the snowboard binding 1, and a front running position F made in thick lines. The legrest 4 can be pivoted from the front driving position F to allow easy entry according to the arrow P1 back to the entry position E 6/10
