Definitions

• the invention relates to a ski binding with a shoe or sole holder arrangement with an adjustable trigger resistance, the sole and / or at least one sole end of which can be released in the cross-ski direction.
• the release resistance in the ski direction is independent of the direction. This also applies if the skis are making fast turns or when driving at an angle, i.e. when driving in the direction of a slope with strong edges.
• the object of the invention is now to vary the triggering behavior of a ski binding in adaptation to the respective skiing situation.
• This object is achieved according to the invention in a ski binding of the type mentioned at the outset in that the release resistance effective in the cross-ski direction can be changed in a direction-dependent manner by a torque which is effective with one-sided edge use of the ski between the ski and boot with respect to a longitudinal axis of the ski, in such a way that in the cross-ski direction to the load constant ski or sole longitudinal edge has a different release resistance than the other or unloaded ski or shoe longitudinal edge.
• the invention is based on the general idea of achieving a release behavior of the binding that is asymmetrical in the direction of the ski when the skis are loaded on one side on one longitudinal edge. Such situations occur when cornering; here practically only the inside of the long ski edges are loaded. The same applies when driving diagonally across a slope; Here, the long side ski edges are primarily used, while the long side ski edges remain unloaded. In the invention it is now achieved that a lateral release to the loaded ski edge against a different release resistance than a release to the unloaded ski edge. This takes into account the fact that the skier stresses his muscles accordingly on one side of the longitudinal ski edges.
• the release resistance in the direction of the ski is greater towards the loaded sole or longitudinal edge than towards the other sole or longitudinal edge.
• the invention is not limited to such an interpretation of the binding. Rather, it can also be provided for unloaded or unloaded soles. Provide an increased triggering resistance in the ski cross direction towards the longitudinal edge of the ski. Despite the asymmetrical release characteristic, the binding can have a construction that is symmetrical to the vertical longitudinal plane of the ski.
• both the support elements and the associated support surfaces are arranged symmetrically to a vertical central longitudinal plane of the ski, but each individual support surface is asymmetrical to a plane parallel to the vertical and longitudinal axis of the ski, which is the center of the support element assigned to the respective support surface enforced.
• the asymmetry of the support surface can be based on the fact that the support surface has a sideways inclination in the cross-ski direction at least in some areas and / or is designed with different surface areas such that the support element slides over areas with different coefficients of friction during relative movements between the support element and the support surface.
• the desired asymmetrical tripping characteristic can thus be achieved.
• the binding can in principle be designed so that the friction that occurs is dependent on the vertical load that the ski boot exerts on the ski.
• the release force to be released to release the binding can also be changed as a function of the load, such that the vertical load which occurs in a typical driving manner leads to a certain complication of the release of the binding, while a release of the binding is facilitated at low vertical loading.
• This takes into account the fact that the muscles of the skier are more tense in a typical driving style and are well prepared for shock loads due to the posture typical of the increased vertical load.
• the binding behaves stiffly in a typical driving style, while triggering is facilitated in an untypical driving style.

• the skis 1 are typically well known, such that the inside ski longitudinal edges 1 ⁇ cut more or less strongly into the respective slope, while the outside ski longitudinal edges 1 are lifted off the respective slope.
• a greater or lesser torque occurs between the respective ski 1 and the associated ski boot 100, such that the inside sole length edge 100 ⁇ of the ski boots 100 is pushed against the ski 1, while the other side sole edge 100 > ⁇ tries to stand out from the respective ski 1.
• a torque with respect to a longitudinal axis of the ski is transmitted between ski boot 100 and ski 1.
• the unequal loading of the longitudinal ski edges 1 and 1 can be used to ensure that a ski binding in the cross-ski direction towards the loaded longitudinal ski edge has a different triggering characteristic than towards the unloaded longitudinal ski edge.
• a sliding plate 2 is attached to a ski 1 in a ski-like manner.
• a sole 4 of a ski boot 5 is supported on the stand or pedal plate 3 and is held on the ski 1 with the help of sole holders 6 of a shoe or sole holder arrangement.
• the sole holders 6 are prestressed in the ski transverse direction against the sole 4, which is symbolically represented by spring means 7.
• the spring means 7 enable the sole holders 6 and thus the shoe 5 held therein to be adjusted.
• the spring means 7 of the sole holder 6 counteract the transverse adjustments of the ski boot 5 and thereby form a release resistance.
• This tripping resistance can be set using conventional means.
• the transverse adjustments of the ski boot 5 remain within a so-called elastic range of the binding, the restoring forces of the spring means 7 cause the ski boot 5 to be aligned again in the longitudinal direction of the ski after each deflection.
• at least one of the sole holders 6 opens, so that the boot 5 is released.
• the stand or pedal plate 3 comes into contact with a special contact surface 8 on the surface of the sliding plate 2.
• the base or pedal plate 3 can also have point-shaped or line-shaped contact points.
• the coefficients of friction of the interacting surfaces can be specially coordinated. It is also possible to vary the frictional resistance depending on the adjustment path.
• the sliding plate 2 can be subdivided into several, in the exemplary embodiment into five, partial areas 9a to 9e, each of which, for example, has a different roughness and / or consist of a different material and / or have a different surface shape.
• the frictional resistance can increase again if the contact surface 8 with the partial areas 9a or 9e comes into contact.
• the slide plate 2 or its subregions 9 are designed in a ramp-like manner in order to influence the resistance to the adjustment as a function of the adjustment path.
• the outer partial areas 9a and 9e can each be designed as a ramp that rises outwards.
• the vertical load required to achieve the frictional force and thus the frictional resistance depends primarily on the weight of the skier.
• the vertical load can depend on the position of the skier, especially if the stand or pedal plate 3 supports the heel area or toe area of the ski boot 5.
• the edge zones 8 'and 8 "of the contact surface 8 are pressed to different degrees against the sliding plate 2.

Since the partial regions 9a to 9e of the sliding plate 2 are arranged asymmetrically with respect to the edge region 8 ', an asymmetrical must then occur Set the triggering characteristic of the binding, because in the direction of the longitudinal ski edge 1 ', the edge zone 8' can only cooperate with the partial area 9c along a short path, while in the direction of the longitudinal ski edge 1 "there is a large path length for the peripheral zone 8 'on the partial area 9c .
• two supporting elements 10 and 10 ' are arranged on the underside of the pedal plate 3, which are spaced apart from one another in the transverse direction of the ski, and which are symmetrical to a vertical longitudinal center plane L of the ski 1 when the pedal plate 3 is its middle one shown in FIG. 2 Location, ie their normal position when skiing.
• the sections 11a and 11'a, 11b and 11'b, and 11c and 11'c are each formed symmetrically to the aforementioned longitudinal center plane L of the ski 1, the sections 11a and 11'a ramps descending towards the sides of the ski, the sections 11c and ll'c ramps descending towards the center of the ski and the sections 11b and ll'b form parallel planes towards the top of the ski.
• the centers of the support elements 10 and 10 ' are each positioned at the transitions between the sections 10b and 10c or 10'b and 10'c.
• the overall symmetrical construction with respect to the vertical longitudinal center plane L of the ski 1 has a direction-dependent one Behavior when the ski 1 is loaded on one side, for example when cornering. When cornering, practically only the inside edge of the ski tread is loaded.
• the ski 1 in Figure 2 may be loaded on the left edge, i.e. the left side of ski 1 may be on the inside of the curve.
• the left support element 10 rests with a significant load on the assigned section 11b of the sliding plate 2. Practically no compressive forces are transmitted from the right support element 10 'to the assigned section 11'b.
• the left support element 10 must move along a comparatively short path over the section 11b until the ramp-like section 11c is reached and only one clearly Reduced frictional resistance can occur because the load acting on the left support element 10 perpendicular to the top of the ski, in cooperation with the section 11c, causes a force component directed towards the outside of the curve.
• the stand or pedal plate 3 is fastened to a carrier part 12 of the binding shown in FIG. 3, the right end of the stand or pedal plate 3 in FIG. 3 pointing backwards in the longitudinal direction of the ski relative to the support member 12 is vertically movable.
• the mobility in the upward direction is limited by a ski-proof guide part 13, which overlaps the facing end of the stand or pedal plate 3 somewhat from above, but allows the stand or pedal plate 3 to move freely in the ski transverse direction.
• the sole holders 6 are mounted on the carrier part 12 so as to be pivotable about substantially vertical axes.
• the carrier part 12 together with the stand or pedal plate 3 is forced into the middle or normal position shown in FIG. 3 relative to the ski 1.
• the sole holders 6 are locked in the position shown relative to the carrier part 12.
• the support part 12 and the sole holder 6 can thus place the front region of the sole of a base plate or pedal plate 3 (not shown in FIG. 3) Reach over or reach over ski boots from the front, from the side and from above and accordingly hold them on the ski 1.
• the tip of the shoe presses against one of the sole holders 6, with the support part 12, together with the stand or pedal plate 3, being displaced in the cross-ski direction against the force of the triggering and locking device if the interfering force is sufficiently high becomes. If an elastic range is exceeded during this shift, the sole holder 6 acted upon by the shoe in the direction of the interference force is unlocked, so that the shoe is released from the ski.
• the triggering force to be overcome in the aforementioned transverse displacement is dependent on the load on the base or pedal plate 3 by the interaction of the contact surface 8 with the slide plate 2 in FIG. 1 or the support elements 10 and 10 'with the slide plate 2 in FIG 2. Changed as outlined above.

Move a short distance over the section 16b of the support surface 16 until the ramp-like section 16a is reached and the supporting forces effective between the support element 15 and the section 16a cause a force component in the direction of the left longitudinal ski edge due to the ramp-like inclination of the section 16a.
• the carrier part 12 is moved to the right in FIG. 2, the left support element 15 only interacts with the ramp-shaped section 16c after a long distance on the section 16b, so that the support forces between the support element 15 and section 16c only after a longer period Transverse movement of the carrier part 12 relative to the ski 1 can cause a force component in FIG. 2 to the left.
• the support elements 10 and 10 ' can also be arranged on the ski side and the slide plate 2 on the underside of the pedal plate 3.

• the release characteristic of the binding also becomes corresponding heavily influenced by the position of the skier. If the skier should have fallen without the bindings being released, the skis are relatively lightly loaded when the skier is lying on the ground.
