Definitions

  • the invention relates to a bearing device for laterally movable vertical support of a ski boot on a ski, with a plate-like support part that can be displaced relative to the ski in the direction of the ski transverse axis and that can be tilted sideways upon displacement, on which the ski shoe rests with its sole.
  • Such bearing devices have the task of reducing the friction between the ski shoe and the ski as much as possible in the case of relative movements between the ski shoe and ski in the transverse direction, in order to ensure as far as possible that the release behavior of the ski binding cannot be influenced by friction when forces act on the shoe sideways .
  • a slide plate is movably arranged on the ski in the cross-ski direction and is elastically supported by means of an annular or loop-shaped rubber spring, such that the slide plate can be moved sideways by stretching the rubber spring. Due to its elastic mounting, the slide plate can also perform a tilting movement as soon as the shoe acts on the slide plate accordingly, ie when the shoe, when the slide plate is moved transversely, the end of the slide plate protruding laterally beyond the ski steps down. In practice, however, this can only occur if the shoe has shifted quite far to the side relative to the sliding plate and relative to the ski. Overall, in the device known from FR-A 23 29 309, an undesirable friction must still be expected, which can impair the release behavior of a binding.
  • the support part is supported by means of balls, but it is not taken into account that the support part has only limited mobility in the cross-ski direction if it is to be held captively on the ski.
  • Modern ski bindings now have a very wide range of elasticity in the direction of the ski, i.e. the ski binding is able to 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 greater than the range of movement of the support part.
  • a bearing device in which the support part is formed by an endless belt, which loosely wraps around a ski-side support part and whose upper section spanning the upper side of the support part in the direction of the ski serves as a storage area for the ski boot. Accordingly, the endless belt can follow any movements of the ski boot sole in the direction of the ski.
  • the disadvantages of the aforementioned storage device are avoided, but it should be borne in mind that the plastic material from which the endless belt must be made in practice can become brittle with prolonged use, especially under the influence of UV radiation, which is extremely high in the mountains can be intense. It should be borne in mind here that 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 device are strongly exposed to the sun.
  • the object of the invention is now to provide a bearing 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 invention provides that, for vertical support of the support part with respect to the ski, sliding surfaces arranged on the supporting part interact with counter-sliding surfaces arranged on the ski and the sliding surfaces and / or the counter-sliding surfaces are inclined to one another in a roof-like manner, such that the support part assumes an increasing inclination with a slope in the direction of displacement with increasing displacement in the direction of the ski transverse axis.
  • 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 counteracting the sideways movement of the ski shoe can occur, even when the shoe sole is pressed firmly, because the between Due to the inevitable inclination of the laterally displaced 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 tries to remove the ski shoe from its normal or central position and thus tries to continue the lateral displacement initiated by the ski shoe.
  • 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 invention is characterized by a simple construction. This is because essentially only sliding surfaces or counter sliding surfaces inclined towards one another must be present, the roof-shaped inclination also being able to be achieved in that the said sliding surfaces or counter sliding surfaces are curved. In any case, this ensures that the side of the supporting part pointing in the direction of displacement is moved obliquely downwards when the support part is moved sideways and the other side is moved obliquely upwards sideways.
  • 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 on the ski boot, not shown, in the cross-ski direction.
  • the binding part 2 or the sole holder 3 can return the ski boot to the middle or normal position when the lateral forces acting on it decrease, if a deflection in the direction of the arrows P ′ or P ′′ predefines the design 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 boot 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 boot 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 displaceability of the support part 5 in the ski transverse direction in modern binding parts 2 is less than the possible transverse displacement of the ski boot within the elastic range of the binding part 2.
  • 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 one another in a roof shape are arranged, which in the central position of the support part 5 shown in FIG. 2 lie on correspondingly inclined counter-sliding surfaces 7' and 7 '' of a bearing part 8 fixed to the ski.
  • 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 sole edge 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 tends to tip 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 shifted sideways, such that the upper side of the support part forms a ramp supporting the ski boot sole with a slope in the direction of the ski.
  • 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 extending in the direction of the ski, the central regions of which, according to FIG. 5, run parallel to the upper side 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 whose free ends 16 'and 16''are angled upward within the opening 13 are.
  • the support part 5 is arranged displaceably in the ski transverse direction between the webs 9.
  • This support part 5 has an essentially 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 supporting 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 ends 16 'and 16''of the leg spring 16 lie against 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 by the support part 5 to the left. This creates a restoring force acting on the support part 5, which tries to hold the support 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 each other when shifting 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, wherein the sliding part 11 on the bearing part side can 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.
