Definitions

  • the invention relates to a toe piece according to the preamble of claim 1.
  • the housing receiving the release spring has a back on which, in the driving position, a sole holder with a three-point support, which is approximately circular in plan view, is supported.
  • the sole holder is pressed against the rear of the housing by a pull rod loaded by the release spring.
  • This toe can be triggered in the event of a pure tumble as well as a backward fall and also in the event of a backward fall of the skier.
  • the release force required can be changed by adjusting the preload of the release spring and by shifting the upper support point of the sole holder on the rear of the housing.
  • This toe has the disadvantage that it can only be used on shoe soles with exact dimensions, because his sole holder can not be adapted to different dimensions of the thickness and the circumferential surface of the shoe sole.
  • the toe piece according to the first version of DE-OS 30 20 346 has a ski-proof housing in which a release spring with an adjustable preload is accommodated.
  • This spring is penetrated by a pull rod, which ends at its end facing the ski boot in a bearing eye in which a connecting piece is accommodated.
  • the latter is penetrated by a set screw.
  • the two ends of the set screw are mounted in a sole hold-down device, which - seen in plan view - consists of a central part running transversely to the toe piece and two legs attached to it at an angle. The middle part is pulled by the release spring against the projecting edge of the housing, with a three-point support.
  • a pin is vertically attached to the ski, on which a housing holding a sole retainer for a release spring is mounted.
  • a three-point support namely the housing on the pin.
  • the sole hold-down can not only pivot in a plane parallel to the top of the ski, but it can also be raised when the skier falls backwards.
  • the sole hold-down is designed as a rigid body that cannot adapt to the shape of any shoe sole.
  • a first version (see the Fig. 1 - 3) is housed here in a ski-fixed housing a tension rod acted upon by a compression spring, on which a piston equipped with an annular groove is fastened.
  • the base of the housing is extended towards the ski boot and carries two vertical swivel axes on which swivel levers are mounted, the longer lever arms of which come into contact with the sole of the boot.
  • the shorter lever arms of the two swivel levers engage in the ring groove of the piston.
  • a type of anchor is seated on the tie rod acted upon by a tension spring, which engages in bores in the shorter lever arms of the two pivot levers.
  • the toe piece allows differently designed shoe soles to be attached to the ski. If the skier falls backwards, the ski boot is not released.
  • the invention has for its object to eliminate the disadvantages of all known designs and to create a toe that on the one hand automatically adapts to differently sized shoe soles, and on the other hand a release of the ski boot of the skier both in a pure lintel as well as in a backward fall and also makes it possible in the event of a reverse turn.
  • the measure of claim 2 ensures that a slight pivoting of the two angle levers occurs with thicker shoe soles. This pivoting thus facilitates the entry of the skier with his ski boot.
  • the subject matter of claim 3 enables a good distribution of the contact pressure originating from the release spring to the upper and lower regions of the bearing part.
  • the subject of claim 6 ensures reliable guidance of the pull rod in the housing.
  • the bearing part is accelerated to return to the starting position (driving position) when the bearing part is pivoted very large.
  • the bearing part is centered in a simple manner by the subject matter of claim 12.
  • claim 17 prevents the skier from being injured by the toe piece in the event of a fall and at the same time simplifies the design of the support area.
  • the distance of the support area from the lower contact surface can be varied within wide limits.
  • the ratio of this distance to the distance between the two other contact surfaces, which is protected in claim 19, has proven to be particularly advantageous.

  • the toe piece is designated 1 in its entirety. It has a housing 2 which is attached to the top 3a of a ski 3 by means of screws 3b, which are only indicated.
  • a Coil spring trained trigger spring 4 housed, the bias can be adjusted in a conventional manner by a threaded sleeve 5.
  • the release spring 4 is arranged between a spring plate 6 and a bearing bush 7, which is mounted in a vertical transverse wall 2a of the housing 2.
  • the trigger spring 4 is penetrated in the axial direction by a pull rod 8, on one end 8a of which the threaded sleeve 5 is screwed on and the other end 8b of which is riveted to the vertical leg 9a of an angular slide 9 which is guided in the housing 2 with its other leg 9b is.
  • a vertical bar 10 which is formed by a profiled sheet steel strip and the function of which is still described in detail.
  • this bearing part 11 is frame-shaped, ie provided with a through-opening 11g for the pull rod 8, and - viewed in side view - has approximately the shape of a C (cf. FIG. 11).
  • the upper leg of the C is formed by a transverse plate 11b, whereas the lower leg consists of two tabs 11c1 and 11c2 arranged symmetrically with respect to the vertical longitudinal median plane of the toe piece 1.
  • the longer lever arm 13a, 14a of each angle lever 13, 14 has an essentially U-shaped cross section, with axes 15-18 being arranged in the two legs, on which rollers 19-22 are mounted.
  • the upper legs of the longer lever arms 13a, 14a are supported on the top of the shoe sole.
  • the shorter lever arms 13b, 14b of the two angle levers 13, 14 are supported in a known manner on the vertical bar 10 fastened on the pull rod 8.
  • the transverse wall 2a of the housing 2 has, to the upper contact surface 2b2, a rearward, approximately horizontal projection 2c, which is rectangular in plan view and which engages in a recess 11d of the bearing part 11 with play.
  • the upper boundary surface 11e of the bearing part 11 located below the recess 11d is at a distance of a few millimeters from the projection 2c.
  • the bearing part 11 moves somewhat upwards depending on the thickness of the ski boot sole.
  • the bearing part 11 also experiences a pivoting movement by a small angle ⁇ in addition to the upward displacement. It is not necessary to adjust the height of the two angle levers 13, 14 to the different thickness of the ski boot soles, since their height is adjusted automatically.
  • the lower contact surface 2b1 is interrupted in its central region by a lower projection 2d, the boundary line - seen in plan view - is formed by a rectangle and an isosceles triangle.
  • This projection 2d designed in the manner of a wedge is assigned a recess 11f in the bearing part 11, which is adapted to the outline of the projection 2d (see FIG. 1a).
  • the bearing part 11 in FIG. 1 is pivoted counterclockwise.
  • the trigger spring 4 is biased more strongly, and the bearing part 11 is raised relative to the driving position until the upper boundary surface 11e in the groove between the projection 2c and the upper contact surface 2b2 (first phase, see Fig. 4).
  • the lower counter surface 11a 1 of the bearing part 11 is lifted off the contact surface 2 b 1 of the housing 2, but the bearing part 11 is still guided on the lower projection 2 d of the housing 2 (second phase, see FIGS. 5 and 5 a) .
  • the bearing part 11 is first pivoted counterclockwise in the manner described above until the position shown in FIG. 5a is exceeded. Subsequently, the bearing part 11 is rotated in a transverse plane on the longitudinal axis of the ski. This is made possible by the fact that the through opening 11g has ample play with respect to the pull rod 8. During this rotation, the upper region of the bearing part 11 is held in place by the upper projection 2c of the housing 2, which engages in the recess 11d with play. In the lower region of the bearing part 11, the recess 11f is lifted off the lower projection 2d of the housing 2, after which the bearing part 11 swings transversely to the longitudinal axis of the ski 3 may (third phase, see Fig. 6 and 6a). The vertical bar 10 releases the shorter lever arms 13b, 14b of the two angle levers 13, 14, which makes it easier for the skier to get out of the toe piece 1 with his ski boot (see FIGS. 6, 8 and 10).
  • the return of the bearing part 11 to the driving position or to the entry position takes place through the wedge-like design of the front side of the lower projection 2d of the housing 2, on which wedge the boundary edge of the recess 11f in the bearing part 11 is supported (see FIG. 6a).
  • the bearing part 11 is pulled by the release spring 4 in the direction of the contact surface 2b1 of the housing 2 until the position shown in Fig. 1a is reached.
  • the front jaw 1 'according to Fig. 14 differs from the front jaw 1 described first in that between the metal housing 2' and the metal bearing part 11 'an intermediate piece 25 is arranged, which is made of a low-friction but not deformable material, e.g. is made of Delrin, which reduces friction.
  • This intermediate piece 25 is equipped with a hook 25a, which can be fixed to a rib 2'g of the housing 2 '.
  • the intermediate piece 25 lies with the angled section 25c of its front 25b on the upper projection 2'c of the housing 2 '.

  • the trigger spring 4 ⁇ is biased more strongly, and the lower counter surface 11 ⁇ a1 of the bearing part 11 ⁇ is lifted from the lower contact surface 2 ⁇ b1 of the housing 2, until the lower projection 2 ⁇ d the recess 11 ⁇ f in the bearing part 11 ⁇ has left and the counter surface 11 ⁇ a2 bears on the third contact surface 2 ⁇ b3 (see FIGS. 19 and 20).

Subsequently, the bearing part 11 ⁇ is rotated in a transverse plane on the longitudinal axis of the ski. This will be there by allows that the through hole 11 ⁇ g compared to the tie rod 8 ⁇ has ample play. During this pivoting, the bearing part 11 ⁇ is pivotably supported by the upper projection 2 ⁇ c of the transverse wall 2 ⁇ a of the housing 2 ⁇ , which engages in the recess 11 ⁇ d of the bearing part 11 ⁇ .

  • This measure takes place in the first phase of the surface 11 ′′′ a2 on the associated end face of the transverse wall 2 ′′′ a, and the distance "b", which increases in the third embodiment with increasing pivoting angle of the bearing part 11 ⁇ , in the second Phase kept constant for all values of the swivel angle.
  • the edge 2 IV b3 of the transverse wall 2 IV a and an inclined surface 2 IV e is formed between the transverse wall 2 IV a and the top of the housing ses 2 IV runs.
  • 25 - 25c shown sixth embodiment of a toe 1 V has the advantage that the third surface 2 V b3 is formed by part of a circular cylinder, and that the associated third counter surface 11 V a3 on the bearing part 11 V from a groove is formed, which is also limited by a circular cylindrical surface.
  • This solution has the advantage that the distance "b" remains constant in the second phase during the swiveling process, but that due to the size of the surface contact during use of the toe piece 1 V there is practically no wear.
  • FIG. 26 shows a seventh embodiment of a front jaw 1 VI , in which the upper sides of the housing 2 VI and the bearing part 11 VI are convexly curved. This has the consequence that the third support area 2 VI b3 for the bearing part 11 VI is reduced to two points 2 VI b 3a and 2 VI b 3b , which are connected by an ideal swivel axis.
  • the two angle levers do not necessarily have to have a U-shaped cross section. Rather, it would be conceivable to equip the bearing part with a separate sole holding-down device, which could be formed by the plate in which the axes of the angle levers are mounted with their upper ends.
  • the intermediate piece between the housing and the bearing part need not be made entirely of a low-friction material. Rather, it suffices to provide this intermediate piece with a layer of such a material in its area adjacent to the bearing part.
  • kinematic reversals of the designs of the bearing part and the transverse wall are also to be protected by the invention.
