Definitions

  • the invention relates to a jaw, in particular a toe for safety ski bindings, which has a sole arranged on a bolt holder and / or two sole holder levers, which are each pivoted laterally about an axis arranged on a housing against the force of a spring, which spring at one end is supported on a set screw and elsewhere on an abutment which is at least ski-proof in the downhill position, the sole hold-down device being designed as a two-armed lever and being pivotably mounted about a further axis running transversely to the longitudinal axis of the ski, of which arms one is assigned to the sole of the ski boot.
  • the sole hold-down is pivotally mounted on the binding housing.
  • An arm connected to the sole hold-down device engages an angled portion of a slide which is also acted upon by lever arms of the sole holder lever.
  • Both the sole holder lever and the sole hold-down device can be pivoted against the force of a spring supported on one end on the set screw and on the other side on the housing, the sole holder lever on the side and the sole hold-down device upward.
  • this known baking has some disadvantages.
  • Baking which at least partially compensates for the increased friction occurring for a backward fall between the sole hold-down device and the ski boot sole, is known from DE-OS 28 12 149.
  • the sole hold-down device of the embodiment of a toe block described in this document is arranged on a holding jaw which is provided both for lateral and for grasping from above the front area of the sole of a ski shoe.
  • a bracket firmly connected to the holding jaw is pivotally mounted about a bearing axis arranged in the housing, about which axis the holding jaw is also pivotably arranged.
  • the housing is rotatably mounted around a pivot pin that is normally on the top of the ski. This pivot pin has a flattened portion that serves as a support for an elastic locking system.
  • the locking system of one embodiment consists essentially of a spring supported on one end on a spring bearing, the other acts on a piston, which in turn carries a tilting element pivotably mounted on it, which is pressed against the pivot pin by the force of the spring.
  • a transverse part connected to the bracket acts on the tilting element, which is partially released from the flattening of the pivot pin and compresses the spring.
  • the invention has therefore set itself the task of designing a jaw of the type mentioned in such a way that it does not have the disadvantages of known solutions mentioned has that it is structurally simple, with compensation for the additional frictional forces occurring in the event of a fall backwards and possibly also forward in the event of a fall between the ski shoe sole and the sole hold-down device or between the ski shoe sole and the top of the ski or a tread plate arranged in the cheek area this should also give a constant triggering force for the possible fall directions.
  • the abutment of the spring in the housing is slidably mounted in the longitudinal direction of the ski and is supported in the downward position of the jaw on the second arm of the hold-down device, and in that the further axis provided for the pivotable mounting of the sole hold-down device an intermediate part arranged on the bolt, preferably adjustable in the vertical direction thereof, and that the arm of the sole holding-down device associated with the shoe sole provides the. If necessary, the sole of the shoe also grips from below.
  • This baking is very simple. Because the sole hold-down device itself holds the abutment of the spring in the downward position, there is a direct transmission of force from the sole hold-down device to the spring supported on the abutment. The result is that when the sole hold-down device is pivoted about its axis by a force acting on it .. vertically optionally in one or the other direction, a displacement movement of the abutment which is dependent on the pivot angle takes place, as a result of which the spring can relax somewhat. The force transmitted by the spring to the sole holder lever which can be swung out laterally is thus reduced. If the sole hold-down device also grips under the ski shoe sole, the lateral release force is also reduced in the event of increased ball pressure, since this also pivots of the sole hold-down and thus a displacement of the abutment of the spring is effected.
  • a further feature of the invention is that the further axis is formed by two axle journals arranged on the intermediate part, a leg spring being held on at least one of the axle journals, the legs of which are supported on the sole retainer engaging in a recess in the latter.
  • the leg spring not only causes the sole hold-down device to be reset after the ski boot is released, it also forms a stop for the sole hold-down device to pivot too far as soon as its two legs strike one another while the sole hold-down device is being pivoted.
  • the arm of the sole holding-down device which is assigned to the ski shoe sole has an extension pointing in the direction of the upper side of the ski, on which a step area under the ski shoe sole is provided.
  • abutment of the spring acts under the action of the spring on a support member which is slidably mounted together with the abutment in the housing and, viewed in side view, is inverted L-shaped, about which parallel to the top of the ski leg of the support part of the sole hold-down is supported.
  • the arm of the sole holding-down device holding the abutment of the spring in the downward position is provided with a rotatably mounted roller at its free end region.
  • a perfect pivoting of the sole hold-down device is ensured according to a further feature of the invention in that the arm of the sole hold-down device is supported on the support part or on the abutment of the spring in a plane normal to the support surface provided on the support part or on the abutment.
  • FIG. 1 shows a side view of a toe piece according to the invention in section and FIG. 2 shows a section along the line II-II of FIG. 1.
  • a housing 2 is fastened on a ski 1 by means of screws 2a.
  • the housing 2 can also be arranged on a base plate which, in a manner known per se, can be displaced on a ski-fixed guide rail in the longitudinal direction of the ski and can be locked in different positions.
  • two sole holder levers 3 are mounted symmetrically to the longitudinal axis of the ski 1 so that they can be pivoted out laterally about axes 4, only indicated, which run perpendicular to the upper side of the ski.
  • the sole holder levers 3 are configured in two arms in a manner known per se, one of which arms is assigned to the lateral region of the sole of a ski boot 6 and the other engages on the one end region of a pull rod 7 and on a central wall 20 of the housing 2 running perpendicular to the upper side of the ski is supported.
  • the pull rod 7 passes through the central wall 20, a support part -8 and a sleeve-shaped abutment 9 supported thereon under the action of a spring 10 and is anchored at its other end in a set screw 11.
  • the spring 10 is arranged coaxially to the tie rod 7, one end at Abutment 9 and supported on a second abutment 12 arranged on the adjusting screw 11 in a manner known per se.
  • the preload of the spring 10 can be adjusted by means of the adjusting screw 11, the respective spring preload can be read off on a display device 13 known per se and indicated in FIG.
  • the support part 8, viewed in side view, is approximately L-shaped.
  • the abutment 9 of the spring 10 is supported on one leg 8a of the support part 8, the second leg 8b passes through a recess 20a in the central wall 20 of the housing 2, which is approximately perpendicular to the upper side of the ski.
  • An arm 14a of a sole hold-down supported on the second leg 8b of the support part 8 14 holds the support part 8 and with it the abutment 9 in the downward position.
  • the arrangement of the support part 8 and the abutment 9 within the housing 2 is so made that these two components can be displaced in the longitudinal direction of the housing 2 in a manner to be described.
  • a threaded bolt 15 which runs perpendicular to the top of the ski and is held in the housing 2, there is also an intermediate part 16 provided with a thread.
  • the intermediate part 16 is provided with two axle journals 16a which run transversely to the longitudinal axis of the ski and are arranged symmetrically thereto. on which the sole retainer 14 is pivotally mounted.
  • the bolt 15 is provided with a screw head, so that by rotating the bolt 15 by means of a tool inserted into the screw head, the intermediate part 16 and thus the sole retainer 14 of the bolt 15 can be adjusted in height, as a result of which the sole retainer 14 can be adapted to differently sized ski shoe soles.
  • the sole hold-down device 14 is provided with an area 14b which overlaps the ski shoe sole in a manner known per se.
  • a tread area 14c is provided which can be acted upon from the underside of the tip area of the shoe sole when the ski boot 6 is inserted into the cheeks. Due to the arrangement of the axle journals 16a, the sole hold-down device 14 forms a two-armed lever, one arm of which encompasses the area 14b which overlaps the ski shoe sole and the tread area 14c and the other arm 14a holds the support part 8 in the downward position.
  • the arm 14a of the hold-down device 14 carries a rotatably mounted roller 17 at its free end region.
  • a leg spring 18 is held firmly and non-rotatably between the sole hold-down device 14 and the intermediate part 16.
  • the two legs of the leg spring 18 run approximately parallel to one another and are each supported on the upper or lower edge region of a recess 14b of the sole hold-down device 14. in the downhill position
  • roller 17 and the axle journals 16a are / in a plane normal to the surface, which cooperates with the roller 17 and is provided on the support part 8, in this embodiment flat surface.
  • the ski boot acts on the sole hold-down device 14 with a force, as shown by the arrow F z + in FIG.
  • the sole hold-down device 14 pivots around the axle journals 16a against the force of the leg spring 18.
  • the roller 17 arranged on the arm 14a of the sole holding-down device 14 rolls during this pivoting movement on the leg 8b of the support part 8. Since the movement of the roller 17 takes place along a circular arc, the support part 8, which is under the action of the spring 10, moves in the longitudinal direction of the ski towards the sole hold-down device 14, the spring 10 can relax somewhat. As a result, the force against which the sole holder levers 3 pivot is reduced.
  • the extent to which the spring 10 relaxes depends on the extent to which the sole holding-down device 14 swings up. The greater the force component acting on the sole hold-down device 14, the more pivoting out of the sole holder lever 3 is facilitated.
  • the sole hold-down device 14 is reset by the leg spring 18.
  • the leg spring 18 also forms a stop for pivoting the sole hold-down device 14 too far as soon as its two legs abut against one another during pivoting of the sole hold-down device 14.
  • the sole of the ski shoe acts on the tread area 14c of the sole hold-down device 14.
  • the sole hold-down device pivots downward about the axle journals 16a, in the direction of arrow F z the roller 17 slides along the support part 8, describing a circular arc upward, which Spring 10 can relax.
  • the invention is not restricted to the exemplary embodiment shown. Further modifications are possible without leaving the scope of the scope of protection. It is thus possible to guide the roller of the sole hold-down device along a control curve formed on the support part, which can optionally also be provided with a locking recess which fixes the roller in the downward position. With regard to the effective length of the lever arm conditions on the sole hold-down device, the designer is given a great deal of latitude. It is also conceivable to design the sole hold-down device without a tread area, as a result of which the sole hold-down device overlaps the ski shoe sole in a conventional manner — only from above. Furthermore, it is possible to support the sole holding-down device directly on the abutment and to dispense with the supporting part.
