Definitions

  • the invention relates to a toe piece according to the preamble of claim 1.
  • the object of the invention is to eliminate this disadvantage and to provide a toe piece in which both angle levers are raised with respect to the top of the ski in the event of a backward lintel.
  • the toe piece according to FR-A 2 421 643 has two side angle levers, which are mounted in the housing and are used to hold the ski boot, but there is a separate sole hold-down device here. If the skier falls backwards, this sole hold-down is raised on the side of the triggering angle lever, so that the release of the ski boot on this side is facilitated.
  • This embodiment is complicated in its construction due to the sole holding-down device which can be pivoted in a transverse plane of the toe piece.
  • the measure of claim 2 ensures safe guidance of the bearing part at the beginning of a backward fall.
  • the subject of claim 3 enables a safe guidance of the bearing part on the housing at the beginning of a backward fall of the skier and a subsequent release of the bearing part, which enables the same to pivot in a transverse plane to the top of the ski.
  • the bearing part is locked against a rotational movement in the direction until an angular position determined in advance by the designer is reached.
  • the solution according to claim 4 has the advantage of simple assembly.
  • the subject of claim 7 ensures surface contact of the bearing part on the housing during the entire backward fall or at the beginning of a backward fall. As a result, the wear of the bearing part and the binding housing is reduced.
  • the measure of claim 8 ensures that in the event of a backward fall of the skier, pivoting of the bearing part about an ideal axis running in the longitudinal direction of the ski only occurs when the bearing part has already covered a predetermined path upwards, ie a distance away from the ski .
  • the subject of claim 8 is thus a variant of the solution specified in claim 3.
  • FIG. 1 is a vertical longitudinal central section through a first embodiment in the driving position and Fig. 2 is an associated plan view, partly cut along the line II - II in Fig. 1.
  • Fig. 3 is a vertical longitudinal central section represented by this embodiment in the case of a backward camber and in FIG. 4 a top view in the case of a camber.
  • FIG. 5 shows a view in the direction of the arrow V in FIG. 1 and FIG. 6 shows the same in the case of a reverse turning fall.
  • Fig. 7 is a side view of the housing and Fig. 8 is a section along the line VIII - VIII in Fig. 7.
  • the bearing part is shown in the diagram. 10 shows a vertical longitudinal central section through a second embodiment in the driving position and FIG. 11 shows a front view of the bearing part of this embodiment.
  • FIG. 12 shows a front view of the bearing part of this embodiment.
  • the bearing part of the second embodiment is shown in the diagram.
  • the toe piece shown in FIGS. 1 to 9 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. In the housing 2, a release spring 4 designed as a helical spring is accommodated, the pretensioning of which can be adjusted in a manner known per se by means of a threaded sleeve 5.
  • the trigger spring 4 is arranged between two spring plates 7, 8, of which the spring plate 8 rests on a transverse wall 2a of the housing 2.
  • the trigger spring 4 is penetrated in the axial direction by a pull rod 6, at one end of which the threaded sleeve 5 is screwed on and the other end of which is riveted to a vertical swivel 9a of an angular slide 9.
  • the two sections 11a, 11b are connected to one another by three transverse webs 11e, 11f and 11g, as a result of which two free spaces, namely a lower free space 11n and an upper free space 11p, are formed.
  • the lower crosspiece 11g is used to rest against the vertical leg 9a of the slide 9.
  • the end face of the crosspiece 11g forms an acute angle ⁇ with the vertical leg 9a of the slide 9, the upper edge of the crosspiece 11g being rounded (see FIG. 1 ).
  • the bearing bores 11c and 11d are penetrated by bearing bolts 12a, 12b, on which angle levers 13a, 13b are pivotably mounted.
  • the shorter lever arm of each angle lever 13a, 13b bears against the leg 9a of the slide 9 and is acted upon by the release spring 4 by means of the pull rod 6.
  • the two angle levers 13a, 13b are pressed against the cap of the ski boot 15.
  • 14 with rollers are designated, on which the sole of the ski boot 15 is supported in the riding position of the toe 1.
  • the projection 2g leaves the lower free space 11n between the two sections 11a, 11b of the bearing part 11 and this can pivot due to the game between the stub axles 10a, 10b and the recesses 2d1, 2d2 about a longitudinal axis of the front jaw 1 ideal axis (see Fig. 6).
  • this causes the friction between the force B (see Fig. 4) pivoting angle lever 13a and 13b and the ski boot 15 lowered, and the ski boot 15 can leave the front jaw 1 more easily.
  • the forces A and B form a resultant, which is exerted by the ski boot 15 on one of the two angle levers 13a, 13b.
  • this toe 1 is based on a controlled diagonal release in the event of a reverse turn.
  • the toe 1 ' has on the ski boot 15' with the tread plate 16 'facing the end face 2'b of the housing 2' an approach 2'c, but to which stub axles 10'a, 10'b are attached.
  • the bearing part 11 ' is plate-shaped, with an upper free space 11'p being recessed in the plate, which has open recesses 11'k1, 11'k2 on both side surfaces towards the top. In these recesses 11'k1, 11'k2 the two axle stubs 10'a, 10'b are inserted during assembly.
  • an approximately T-shaped recess 11'm is provided in the bearing part 11 ', which protrudes with its stem upwards.
  • the pull rod 6 ' passes through a bearing bore in the transverse wall 2'a of the housing 2' and is then guided in the recess 11'm of the bearing part 11 'and riveted at its end to the vertical leg 9'a.
  • the invention is not limited to the exemplary embodiments shown in the drawing and described above. Rather, different modifications of the same are possible without leaving the scope of the invention.
  • the use of the projection and that of the T-shaped recess can be exchanged in both exemplary embodiments.
  • the gap between the bearing part and the end wall of the housing can be filled with a rubber-elastic sealing material.
  • the rollers are mounted on the pivot axes for the angle levers.
