Definitions

  • the invention relates to a storage device for laterally movable vertical support of a ski boot on a ski, with a plate-like support part which can be displaced relative to the ski in the direction of the ski transverse axis and on which the sole of the ski shoe rests, in particular in the ball area.
  • Such storage devices are known, for example from DE-OS 25 53 169, and have the task of reducing the friction between the ski boot and ski as much as possible in the case of relative movements between the ski boot and the ski in the direction of the ski, in order to ensure as far as possible that the triggering behavior of the Ski binding cannot be influenced by forces acting on the shoe sideways.
  • the support part is provided with as little friction as possible, for example in accordance with DE-OS 25 53 169 already mentioned, by balls.
  • the support part can only have limited mobility in the ski transverse direction if the support part is to be held captively on the ski or on a part on the ski side.
  • Modern ski bindings now have a very wide range of elasticity in the direction of the ski, ie the ski binding can return the ski boot to the normal position even if it was previously deflected relatively far from the normal position due to lateral forces.
  • the range of elasticity of the ski binding in the ski transverse direction can be larger than the range of movement of the support part.
  • this is equivalent to the fact that the support part can only follow the ski boot along a limited path in the cross-ski direction when the ski boot is triggered sideways, without a relative movement having to occur between the ski boot and the support part.
  • the ski boot moves a little further in the direction of the ski when it is released sideways until the trigger point of the ski binding is exceeded.
  • this phase of movement of the ski shoe there is necessarily a greater degree of friction between the sole of the ski shoe and the support part which remains in its end position.
  • the sole of the ski boot now - for example in the event of a forward sideways fall - Pressed with greater force on the support part, the effective friction between the sole of the shoe and the support part can reach considerable dimensions, so that the total resistance counteracting release of the ski shoe from the binding increases undesirably.
  • bearing devices of the type specified at the outset are questionable for ski bindings with a large range of elasticity in the cross-ski direction.
  • a bearing device in which the support part is formed by an endless belt which movably wraps around a ski-side support part and whose upper section spanning the upper side of the support part in the ski transverse direction serves as a bearing surface for the ski shoe. Accordingly, the endless belt can follow any movements of the ski boot sole in the direction of the ski.
  • the disadvantages of the storage device mentioned at the outset are thus avoided.
  • the plastic material from which the endless belt must be made in practice can become brittle over a long period of use, in particular under the influence of UV radiation, which can be extremely intense in the high mountains.
  • inexperienced skiers in particular take a relatively large number of breaks when skiing. The skis are often put down so that the circumferential bands of the support devices are strongly exposed to the sun.
  • the object of the invention is now to provide a storage device which is practically maintenance-free and durable on the one hand and on the other hand can practically not influence the triggering behavior of the ski binding.
  • the ski boot supported thereon is mounted with essentially negligible friction in the direction of the ski.
  • the support part dragged along by the ski shoe sole reaches its end position assigned to the respective direction of displacement when the ski shoe is moved sideways by external forces, no increased resistance to counteract the sideways movement of the ski shoe can occur, even when the shoe sole is pressed firmly, because the between Due to the skewed position of the support part, the sole of the shoe and the support part act as a force component which is oriented in the direction of the ski and which remove the ski shoe from its normal or central position and thus from the ski shoe initiated sideways shift seeks to continue.
  • the zone in which the greatest pressure forces occur between the plate-like support part and the sole of the shoe is due to the inclined position of the support part on the opposite side of the ski shoe sole from the respective direction of movement of the ski shoe. Accordingly, a greater sideways movement of the same exerts a torque that increases with the respective vertical load on the support part and tries to eject the ski shoe from the binding to the side.
  • the arrangement according to the invention thus reliably avoids that the resistances counteracting a release movement of the ski boot can increase undesirably shortly before the elastic range of the binding is exceeded.
  • the principle of the invention can be implemented in a structurally particularly simple manner. It is sufficient if on the underside of the plate-shaped support part facing the ski top and / or on the facing top of a ski-side part roof-like inclined sliding surfaces are arranged so that the side of the support part pointing in the direction of displacement in each case when it is moved sideways obliquely downwards and the other Be moved sideways sideways upwards.
  • a basically known front binding part 2 of a ski binding is arranged on a ski 1, which overlaps the toe or the front end of the ski shoe sole in the normal position shown from above and from the side.
  • the binding part 2 or its sole holder 3 can against the force of an invisible spring assembly according to the arrows P 'and P''are deflected sideways when correspondingly large forces act in the transverse direction of the ski on the not shown ski boot.
  • the binding part 2 or the sole holder 3 can reset the ski boot to the middle or normal position when the lateral forces acting thereon decrease, if a deflection in the direction of the arrows P 'or P''is a predetermined one by the construction of the binding part 2 Elastic range is not exceeded. If the elasticity range is exceeded, the ski boot is released.
  • the ball area of the sole of the ski shoe is supported on a bearing device 4, which has a plate-like support part 5 which can be displaced in the cross-ski direction against a return spring and on which the sole of the ski shoe rests.
  • the sole of the ski boot drags the support part 5 in the cross-ski direction until the support part 5 has reached its end position on the right side or its end position on the left side of the ski.
  • the support part 5 is to be arranged on the ski 1 in a sufficiently secure and captive manner, only relatively limited displaceability in the direction of the ski can be ensured with structurally simple means.
  • the range of the displaceability of the support part 5 in the ski transverse direction in modern binding parts 2 is smaller than the possible transverse displacement of the ski boot within the elastic range of the binding part 2.
  • the ski boot as a rule, has to travel a remaining distance in the cross-ski direction in the event of a sideways release before reaching the release point if the support part 5 has already reached its end position in the respective direction of movement, i.e. Between the sole of the ski boot and the support part 5, a larger relative movement takes place shortly before the trigger point is reached.
  • the support part 5 is guided in a special way.
  • FIG. 2 On the underside of the support part 5, sliding surfaces 6 'and 6' 'which are inclined relative to each other in a roof shape are arranged, which in the central position of the support part 5 shown in FIG.
  • the surfaces 6 'and 7' or 6 '' and 7 '' each form inclined planes sloping towards the adjacent longitudinal side of the ski.
  • the contact zone between the sole of the shoe and the support part 5 shifts in the case of its inclined position in the direction of the side edge of the sole which points in the upward direction of the slope of the top of the support part 5.
  • the underside of the ski boot is supported asymmetrically to the longitudinal axis of the ski boot, in such a way that a certain tilting moment arises which tries to tilt the ski boot to the side in the downward direction of the upper side of the support part 5. This effect supports the compensation of the friction between the support part 5 and the ski boot sole.
  • the sliding surfaces 6 'and 6' 'and the counter sliding surfaces 7' and 7 '' can also each be curved or merge into one another.
  • the support part assumes an increasing inclined position in relation to the ski 1 when it is displaced sideways, such that the upper side of the support part forms a ramp supporting the ski boot sole with a slope in the ski transverse direction.
  • the essentially plate-like bearing part 8 is fixedly arranged on the ski 1 on a holding plate 14, on which two approximately horizontal webs 9, which extend in the transverse direction of the ski and face each other, are arranged. Below these webs 9, slot-like channels 10 are cut out in the ski transverse direction. Below the webs 9, the channels 10 have sliding surfaces 11 which extend in the direction of the ski, the central regions of which, according to FIG. 5, run parallel to the top of the ski 1 and the end regions 11 'and 11' 'of which form sloping surfaces towards the adjacent longitudinal side of the ski.
  • the bearing part 8 On its side facing the holding plate 14, the bearing part 8 has a flat depression 12 which tunnels one of the sliding surfaces 11 and merges into an opening 13 between the sliding surfaces 11.
  • leg spring 16 is accommodated, the U-shaped middle section of which comprises a pin 17 on the bearing part 8 and the free ends 16 'and 16''of which are angled upward within the opening 13 are.
  • the support member 5 is arranged to be displaceable in the ski transverse direction.
  • This support part 5 has a substantially flat upper side which has rounded edges like a cushion and extends somewhat above that level which is formed by the upper sides of the webs 9 facing away from the upper side of the ski.
  • the sliding surfaces 19 have end regions 19 ′ and 19 ′′ which are arranged obliquely in accordance with the end regions 11 ′ and 11 ′′ of the sliding surfaces 11.
  • a flange 18 there are projections 20 which cooperate with a stop part 21 to limit the displaceability of the support part 5, which in turn can be formed by an upwardly angled tongue of the holding plate 14 holding the bearing part 18 and from below into one channel 10 protrudes.
  • a filler 23 is arranged in the support part 5, which has a recess 24 for receiving the angled ends 16 'and 16' 'of the leg spring 16.
  • the arrangement shown works as follows: In the illustrated central position of the supporting part 5, the ends 16 'and 16''of the leg spring 16 abut the front ends of the recess 24, the legs of the leg spring 16, which are spread apart resiliently, rest elastically on opposite edges of the recess 12. If the support part 5 is displaced in the ski transverse direction, for example to the left in FIG. 4, the left leg of the leg spring 16 remains in contact with the left side of the depression 12 in FIG. 4, while the right leg is carried along to the left by the support part 5. This creates a restoring force acting on the supporting part 5, which tries to hold the supporting part 5 in the illustrated central position.
  • the support part 5 assumes an increasing inclined position due to the interaction of the sliding surfaces 11 and 19 or the end regions 11 ′ and 11 ′′ or 19 ′ and 19 ′′ with one another when displaced in the ski transverse direction, as described above with reference to FIG. 2 and 3 has been explained.
  • the support part 5 with the flanges 18 can be designed as a sheet metal part, while the bearing part 8 forms a plastic part, the sliding part 11 on the bearing part side being able to be provided with a particularly low-friction coating.
  • leg spring 16 instead of the leg spring 16, other spring assemblies, for example helical springs, can also be arranged.
