Definitions

  • the invention relates to a front bakken according to the preamble of claims 1 and 3.
  • the object of the invention is to eliminate this disadvantage and to provide a toe piece in which the gear ratio mentioned can be changed within relatively wide limits.
  • the second solution specified in claim 3 is somewhat more complicated in its structure than the one dealt with first, but it enables translation by shifting the pivot axis for the compensating lever or by displacing the bores for the pressure pins ratio to vary to a greater extent than in the first solution.
  • the subject of claim 6 makes the structure of the toe more compact.
  • the features of claim 7 have the advantage that a "digging" is no fear of the pressure pin in the S o hlenhal- ter because the cam can be cured.
  • the measure of claim 8 allows the force of the compression spring to be divided into two individual forces in a manner known per se, the force acting on the sole holder being able to be better dimensioned by the further features of this claim.
  • Fig. 1 is a section along the line I - I in Fig. 2 through a first embodiment and Fig. 2 is a section along the line II - II in Fig. 1.
  • Fig. 3 a second embodiment is shown in the vertical longitudinal center section and Fig. 4 is a section through a detail along the line IV - IV in Fig. 3.
  • Figs. 6 to? Cuts through the spring housing of a third embodiment.
  • the front jaw is designated by 1 in its entirety. It has an approximately angular support body 2 in side view, of which one leg 2a forms a step plate and the other leg 2b extends vertically to the top of the ski and carries a spring housing 3 which extends towards the ski tip.
  • an axis 4 is fastened in the leg 2b and runs in the direction of the ski.
  • an angle lever 5 is mounted on this axis 4.
  • the leg 5a of the angle lever 5, which runs parallel to the upper side of the ski, is fork-shaped and, with the two fork teeth, comprises the head 6a of an adjusting screw 6, the lower end of which is guided in a bore 2c of the leg 2a.
  • a sole holder 7 with a threaded hole screwed on further supports the leg 2a of the support body 2 at a lateral distance from the vertical longitudinal median plane of the toe 1 two vertical axes 8, on which angle levers 9 are mounted, which are used to hold the sole of the shoe in one the shoe to be used for the toe pieces.
  • Rollers 14 are mounted in the angle levers 9, which reduce the friction between the shoe sole and the angle lever 9 to be deflected when triggered laterally.
  • a compression spring 10 is accommodated, which runs in the longitudinal direction of the ski and is penetrated by a pull rod 11.
  • This carries a support plate 12 at its end adjacent to the ski boot.
  • a tension toward the ski tip is exerted on this support plate 12 by the compression spring 10.
  • a compensating lever 13 is arranged between the support plate 10 and the two angle levers 9. The plate 12 rests on one side of the compensating lever 13, whereas the other side of the compensating lever 13 bears on the one hand at the ends of the two angle levers 9 and on the other the other leg 5b of the angle lever 5 abuts.
  • the two ends of the angle lever 9 are pressed by the compression spring 10 against the leg 2b of the support body 2 which runs perpendicular to the upper side of the ski.
  • the tie rod 11 passes through a bore 2d in the vertically extending leg 2b of the support body 2, and an oblique bore 13a in the compensating lever 13. Due to the last-mentioned oblique bore 13a, the compensating lever 13 is pivoted without tilting due to the bevel and the ample play Angle relative to the tie rod 11 possible.
  • the front jaw 1 ' differs from the first embodiment in that the support body 2' and the spring housing are formed in one piece. Furthermore, the sole holder 7 'itself is designed as an angle lever, the forked one a leg is pivotally mounted on an axis 7 'on the support body 2'. The axis 7'a is arranged in a shoulder 2'e of the support body 2 '.
  • the two angle levers 9 ' which serve for the lateral holding of the shoe sole, seated on a common A ch- se 9'a.
  • the compensating lever 13 ' is housed inside the support body 2'.
  • the support body 2 ' also has a bore 23 in which a piston 24 is guided, which is acted upon by a coil spring 10'.
  • the front of the piston 24 has a groove 24a running in the direction of the ski, in which a rib 13'a of the compensating lever 13 'which is semicircular in cross section engages.
  • a bevel 24b adjoins the groove 24a.
  • the two angle levers 9 ' are hinged together in the manner of a hinge which is mounted on the axis 9'a.
  • 25 is a spacer sleeve which defines the distance between the two angle levers 9 'relative to the support body 2'.
  • toe 1 ' The operation of the toe 1 'is similar to that of the first embodiment.
  • one of the two angle levers 9 ' is pivoted outwards.
  • the sole holder 7 ' is pivoted counterclockwise.
  • the upper pressure pin 20 is displaced toward the ski tip, which causes the compensating lever 13 'to pivot and thus compression of the coil spring 10.
  • the variant of a toe piece 1 "shown in FIGS. 5 to 7 differs from the toe piece 1 'shown in FIGS. 3 and 4 primarily in that two coil springs 30 and 31 are arranged coaxially in the spring housing 3' instead of a single spring , of which one spring 30 acts on a central piston 32 and the other spring 31 acts on an annular piston 33 surrounding the latter.
  • the two recesses in the support body 2 "running in the longitudinal direction of the ski are arranged such that the upper pressure pin 20 'only on the annular piston 33, the lower pressure pin 21 ', however, presses on both pistons 32 and 33 simultaneously.
  • a set screw 34 is used, the right end of which is guided in FIG. 5 in a blind bore 32a of the central piston 32 and on which a spring plate 35 is screwed, which in a manner known per se relative to the spring housing 3 'is axially displaceable, but is secured against twisting.
  • On the spring plate 35 lie one end of the two coil springs 30, 31, the pretension of which is changed at the same time.
  • the spring housing 3 ' can be provided with a window to indicate the size of the preload of the two coil springs 30, 31.
  • the invention is not tied to the exemplary embodiments shown in the drawing and described above. Rather, various modifications thereof are possible without leaving the scope of the invention.
  • the recesses for the two pins which extend in the axial direction of the front jaw, are arranged higher or lower than shown within certain limits by the designer in order to vary the ratio of the two lever arms of the compensating lever.
  • the two coil springs in the embodiment according to FIGS. 5 to 7 do not have to be simultaneously changed in their pretension. Rather, the setting could also be made individually, as is already known in connection with other constructions.
  • the pressure pin and plate according to FIGS. 3 and 4 can also be formed in one piece.
