Description

The invention relates to a safety binding for alpine board sports, in particular a pairwise to be mounted on a snowboard safety binding, according to the preamble of claim 1.

A safety bond for releasably securing a shoe on a sports equipment, such. As a snowboard, has the task to transfer a control forces of the athlete on the snowboard and to trigger the other when exceeding critical force values to avoid injury, especially the lower extremities. In this case, loss-free transmission of the control forces from the athlete to the sports equipment by means of binding in normal (injury-insensitive) driving operation must be guaranteed by a safety bond.

Compared to alpine skiing, snowboarding with soft boots often causes injuries in the ankle joint. In particular, the injury of ligament and bone structures in the ankle is due to anatomically unfavorable rotations about all axes of the ankle and acting force peaks observed. This injury syndrome is commonly known as Snowboarder's Ankle and is most prone to falling. It can be stated that the risk of injury in case of a fall is greater with more flexible snowboard boots than with stiff snowboard boots. However, in many disciplines of snowboarding, a flexible snowboard boot is preferred by athletes for the practice of specific techniques and tricks. A reduction of the risk of injury to the ankle by the use of stiffer snowboard boots is therefore not appropriate.

The DE 39 18 939 A1 discloses a gliding board, in particular snow gliding board, with two successively arranged at a significant angle to the longitudinal axis of the board bindings for two boots. Characteristic of this invention is that each binding comprises a mounted on the sliding board board and a firmly connectable to the boot cleat, both plates by particularly in the front and rear region preferably substantially centrally or symmetrically to the central longitudinal axis arranged elastic traction means in tight abutment against each other are drawn and that the elasticity of the elastic traction means is dimensioned so that in excessive stresses on the athlete's legs, the cleat relative to the board, tilt at least laterally and preferably also to the front and rear to a limited extent, tilt and expediently limited to a vertical axis can. This proposed solution reduces force peaks and avoids complete separation of the two plates or binding parts from each other.

A particular disadvantage of this invention is that at critical force values no release of the bond takes place. In addition, the binding does not include means for adapting the pretension of the elastic traction means to the individual requirements of the athlete. This is accompanied by the fact that the return mechanism can not be adjusted according to the individual requirements. In addition, it should be mentioned that due to the lack of release mechanism, the binding is not returned by the provision exactly in the starting position. Therefore, even during normal snowboarding, the binding can worsen the transmission of the control forces necessary for snowboarding and therefore appear soft and spongy.

From the DE 44 060 74 C1 discloses a safety binding for snowboards, which has a base plate to which the shoe of a driver is fastened, wherein the base plate is fixable by means of a locking mechanism relative to the snowboard and the locking mechanism releases the fixation when predetermined forces are exceeded. Characteristic of this invention is that the base plate is fixed to the snowboard so that it can rotate when a preset torque is exceeded only about an axis perpendicular to the snowboard surface axis, while remaining fixed with respect to all other directions of movement. This is achieved in that the base plate has a central, central, circular opening into which engages a turntable, which engages over the base plate with a radially projecting edge and thus fixes the base plate in all directions of movement with the exception of a rotation relative to the snowboard and that Part of the locking mechanism is secured to the base plate and a cooperating opposite of the locking mechanism on the turntable.

A disadvantage of this invention, however, is that the invention provides no protection for excessive Dorsalextensionen and supinations when acting critical axial forces.

Finally, the reveals DE 10 2008 051 334 B3 a pairwise to be mounted on a snowboard safety binding with two mutually slidably arranged binding parts, wherein the sliding surfaces are formed as Kugelkalotten, a locking device which locks the position of both binding parts to each other in a normal position, as long as the triggering forces acting on the latching device are below a predetermined threshold at the binding parts arranged attacks that limit the movement of the binding parts relative to each other to a compatible with the anatomical conditions area and an elastic connecting element that generates a physiologically acceptable restoring force against each other when deflecting both binding parts.

However, even this safety bond does not provide adequate protection under load with different critical forces. In addition, after a successful compensation of acting unwanted force peaks no exact recovery of the original state takes place.

The object of the invention is now to propose a safety bond for alpine board sports, which compensates on the one hand the force acting on the athlete unwanted force peaks and on the other hand allows for the compensation of an exact recovery of the original state.

According to the concept of the invention, the safety binding for alpine boarding, in particular a pairwise to be mounted on a snowboard safety binding, from a fixable on the sports equipment lower binding member and fixable on the shoe upper binding member, wherein the binding parts on each other sliding bearing surfaces, on which they support facing bearing surfaces of the other binding part. The bearing surfaces of the two binding parts are formed as surface elements of two spherical caps whose common center of curvature lies above the upper binding part. Furthermore, the safety bond comprises at least one latching and triggering device which locks the position of the upper binding part relative to the lower binding part in a normal position as long as the release forces acting on the latching and triggering device are below a predefinable threshold value. A latching and tripping device consists of a first latching partner placed on the upper binding part and of a second complementary latching partner placed on the lower binding part, one of the latching partners being a receiving element and the other complementary latching partner being a spring-loaded movable latching partner. The safety binding also has at least one elastic connecting element, which is in operative connection with the two binding parts and dimensioned so that it generates a physiologically acceptable first restoring force in its deformation due to a deflection of the upper binding part from the normal position. The two binding parts comprise stops which, when the latching and triggering device is triggered, limit the range of movement of the two binding parts relative to one another to a region which is compatible with the anatomical conditions. The generated by the elastic connecting element first restoring force causes only a shift of the two binding parts to the height of the contact region of the complementary locking partner during the second restoring force generated by the locking and triggering device to a subsequent latching of the two binding parts to re-accept the original position of the upper binding member leads to the lower binding part in the normal position. Characteristic of this invention is that two independently acting latching and tripping devices are provided, wherein one of the two latching and tripping devices essentially triggers at a rotationally acting force or moment and the other latching and tripping device substantially in a translationally acting force triggers.

A rotationally acting force is recorded, for example, during a rotation of the lower leg about its longitudinal axis.

In a preferred embodiment of the invention, the first latching and tripping device is placed in the region of the front end of the safety binding and arranged independently acting second latching and tripping device in the region of the rear end of the safety bond. Structurally, it is provided that the latching and triggering device which essentially triggers a rotationally acting force or moment in the direction of the longitudinal axis of the safety bond and the latching and triggering device which essentially triggers a translationally acting force is arranged orthogonally to the longitudinal axis of the safety bond.

It has proven to be particularly advantageous if the latching and triggering device placed in the region of the front end of the safety bond essentially triggers a translationally acting force and the latching and triggering device placed in the region of the rear end of the safety bond substantially in the case of a rotationally acting force or a moment triggers. In principle, however, the two latching and tripping devices are designed so that the respective other latching and tripping device can be involved in the tripping.

A significant advantage of the invention is particularly noticeable to the athlete when the two locking and release devices each have means for individually setting the threshold value of the corresponding release force of the associated spring-loaded movable locking partner. Thus, on the one hand every athlete according to his needs, the front and adjust rear locking and release mechanism. When using one and the same snowboard by different athletes, for example, by family members, on the other hand, each athlete can generate their own desired driving characteristics of the snowboard using the two locking and release devices.

Preferably, the two complementary latching partners each latching and tripping device for the purpose of optimal sliding or joining together either as a spherical segment and Kugelsegmentpfanne, cone and cone, as a pyramid and pyramid pan or as arbitrarily shaped and mutually compatible body.

It has proven to be advantageous that in the above-described training of the complementary locking partner with one of the locking partner as a receiving element and the other complementary locking partner as spring loaded movable Rastpartner the latter in the recovery of the normal position after a triggering operation due to undesirable force peaks with a clear for the athlete acoustically or tactile perceivable "click" engages or snaps into the receiving element. The athlete thus receives a return information about the resumption of the normal position of both binding parts and thus the restoration of the full controllability of the snowboard after a triggering operation.

An attractive development of this feature of the invention may be that the resumption of the normal position of the two binding parts to one another after a triggering process is indicated using an additional signal generator. For this purpose, this signal generator can be coupled to a power supply which is designed, for example, in the form of a button cell.

It is also essential to the invention that the elastic connecting element is placed as a sheet-like structure on the upper binding part and the lower binding part has an anti-twist device which engages in a form-fitting manner in the elastic connecting element. Although the elastic connecting member made of a fatigue-free high memory material is theoretically deformable in any direction, it is deformed in one plane only according to the present invention. Since the two binding parts slide on each other, therefore, only a compressive stress of the elastic connecting element takes place.

From a manufacturing point of view has proven to be particularly advantageous if the elastic connecting element form-fit in the upper binding member and the rotation are positively placed in the lower binding part, which is ensured by the intervention of the rotation in the elastic connecting element, the elastic operative connection between the two binding parts.

Compared to the prior art, the subject invention further differs in that the upper binding member and the lower binding part each mutually inter-engaging stops and hooks, so that during a triggering operation and the process of resuming the normal position, the two binding parts permanently slide on each other without the To lose contact with each other. That is, even after a triggering process sufficient control forces can be transmitted by the athlete on the snowboard.

The significant advantages and features of the invention over the prior art are essentially:

• • the assumption of the normal position of the two binding parts to each other after the compensation is achieved in cooperation of the restoring forces generated by the elastic connecting element and the restoring forces generated by the spring-loaded locking partner,
• The elastic connecting element is manufactured as a sheet-like component and thus enables a very flat construction of the safety binding,
