Definitions

  • the invention relates to a heel holder "with a base plate to be fastened to the ski or adjustable and lockable in the longitudinal direction of the ski, on which a housing accommodating a locking spring and a locking bolt is arranged, which can optionally be pivoted about an axis normal to the top of the ski relative to the base plate is and on a transverse axis carries a unit consisting of a step spur and a hold-down part, which is assigned a release lever equipped with a control cam.
  • the heel holder of this not yet pre-published type was very simple in its construction and extremely robust in its construction, but it had the disadvantage that in the event of an involuntary release of the front jaw of the ski binding, the release lever, which is formed in one piece with the step spur and the hold-down part had to be swiveled into the entry position by hand to get the ski boot back on.
  • Heel holders have always been proposed, which were always ready for the ski boot to get in, regardless of whether the heel holder was triggered voluntarily or involuntarily or only when the front jaw was released (see AT-PS 341.393), but they were Heel holder somewhat complex in its construction.
  • the invention aims to eliminate the disadvantages mentioned above and to create a heel holder according to the type specified above, which on the one hand any type of trigger is ready for the entry of the ski boot, but on the other hand is extremely simple in its construction.
  • the unit consisting of the step spur and hold-down part which preferably rests on the release lever in the travel position along a parting plane, is connected in an articulated manner to the release lever and under the influence of at least one torsion spring which seeks to pivot it upward and stands at least one compression spring which tries to push the unit away from the transverse axis or from the release lever.
  • At least one hinge axis is provided for the articulated connection of the unit consisting of the tread and hold-down part to the release lever, the recess of which is penetrated by the transverse axis of the release lever being designed as an elongated hole, whereas the Transverse axis of the unit penetrates a hole in the hinge bracket.
  • the invention further provides that the or each compression spring is accommodated in a blind hole in the release lever, the axis of which is aligned with the axis of the joint plate in the Driving position of the heel holder is aligned and, in its front area, is designed in accordance with the cross section of the joint plate, for example, is profiled rectangular.
  • the transverse axis for the release lever is mounted in bearing eyes which are attached to the release lever and protrude laterally into recesses in the unit via the parting plane between the unit consisting of the tread plate and holding-down part and the release lever .
  • the unit consisting of the step spur and hold-down part is provided according to the invention with an attachment which engages in the recessed position of the release lever below the two bearing eyes in the travel position of the heel holder.
  • the invention provides that in order to limit the combined movement of the unit consisting of the step spur and the holding-down part or the articulated bracket relative to the release lever on the latter stop surfaces are arranged.
  • the pivot angle of the unit is limited to about 72 0th
  • leg springs which are intended to bring about the pivoting movement of the unit relative to the release lever.
  • the or each leg spring is mounted on the transverse axis for the release lever, one leg of the Leg spring is supported on a stop surface of the release lever, the other leg, on the other hand, is accommodated with its bent end in a slot-like recess of the unit consisting of the step spur and hold-down part.
  • the bent leg end allows the leg to slide in the longitudinal direction of the recess during the combined movement of the unit.
  • FIG. 1 shows a heel holder according to the invention in the entry position in longitudinal section and FIG. 2 shows the same in the downward position, likewise in longitudinal section, FIG. 3 shows a detail of the heel holder in the downward position in section along the line III-III in FIG. 4 and FIG .4 a section along the line IV-IV in Figure 3 again.
  • Figs. 1 and 2 denotes a ski. on the top la a guide rail 2 is attached. On this the base plate 3 of a heel holder is guided. It can be determined in the selected position by means known per se, not shown for the sake of clarity.
  • On the base plate 3 is a rest spring 4 and a locking pin 10 or the like.
  • Receiving housing 5 rotatably mounted on a vertical axis 6. On the side facing the ski boot, the housing 5 has two bearing eyes 5 ', in which a transverse axis 7 for a release lever 8 is arranged. This carries on its underside a control cam 9, which the locking pin 10 or the like. is assigned, which is acted upon by the detent spring 4 and is guided in the housing 5 in the direction of its axis.
  • the release lever 8 On its front, the release lever 8 carries a unit 13 consisting of a tread 11 and a hold-down part 12. This unit is articulated to the release lever 8 and is under the influence of two leg springs 14, which seek to pivot the unit 13 upwards, and at least a compression spring 15 which tries to push the unit 13 away from the transverse axis 7 or from the release lever 8.
  • the articulated connection of the unit 13 to the release lever 8 is brought about by an articulated salmon 16, the recess 16 'of which the transverse axis 7 passes through is designed as an elongated hole, whereas the transverse axis 17 of the unit 13 / penetrates a bore 16 "of the articulated plate.
  • the latter is accommodated in a blind bore 8 ′′ in the release lever 8, the axis of which is aligned with the axis of the joint plate 16 in the driving position of the heel holder and which is designed in its front region to correspond to the cross section of the joint plate 16 and to permit its pivoting movement
  • This design ensures that the joint plate 16 is properly guided in the bore 8 ′′, irrespective of whether the joint plate, as shown in FIG profile is made.
  • the two leg springs 14 are located on both sides of the link plate 16 and are mounted on the transverse axis 7 for the release lever 8.
  • each leg spring 14 is supported on a stop surface 8' of the release lever 8, while the other leg 14 "is accommodated in a slot-like recess 13 'in the unit 13 consisting of the tread 11 and hold-down part 12.
  • the end of the leg 14 " is arched to facilitate sliding in the recess 13 '.
  • the unit 13 In the driving position of the heel holder, the unit 13 consisting of tread 11 and hold-down part 12 touches the release lever 8 along a parting plane 18. Over this parting plane 18, bearing eyes 19 for the transverse axis 7, which are attached to the release lever 8, project laterally. Furthermore, the unit 13 consisting of tread 11 and hold-down part 12 has a projection 20 which, in the driving position of the heel holder, engages in a recess 21 in the release lever 8 below the two bearing eyes 19. This approach 20 consequently projects on the other side than the two bearing eyes 19 over the parting plane 18.
  • stop surfaces 22, 22 ' are provided on the release lever, which on the one hand limit the pivoting angle of the joint plate 16 and on the other hand that of the unit 13 consisting of the step spur 11 and the hold-down part 12. This is approximately 36 ° for unit 13, but 72 ° for hinge axis 16.
  • the function of the heel holder according to the invention is as follows: in the travel division of the heel holder, the unit 13 formed from the step spur 11 and the hold-down part 12 is pressed against the force by means of the front jaw of the ski binding the springs 14, 15 firmly pressed against the release lever 8 so that both parts touch along the parting plane 18 (see FIG. 2).
  • the release lever 8 In the event of an arbitrary release of the heel holder, the release lever 8 is pivoted out of the driving position about the transverse axis 7 against the upper side la of the ski.
  • the locking pin 10 slides along the cam 9 of the release lever 8, the locking spring 4 being compressed somewhat in the housing 5 at the same time.
  • the unit 13 is pivoted clockwise under the influence of the two leg springs 14 in FIG. At the same time, the unit 13 is also pushed away from the parting plane 18 as a result of the compression spring 15, which only makes pivoting possible. This pushing away of the unit 13 comes about because the compression spring 15, which acts on the end of the articulated bracket 16 mounted in the release lever 8, the latter due to its elongated hole 16 'in Moved towards the ski tip. Accordingly, the unit 13 receives a movement composed of a rotation and a translation, which is limited by the stop surfaces 22 and 22 'on the release lever. In this way it is possible, even after the toe piece has been released, to re-enter the ski binding with the ski boot alone, without the release lever 8 having to be pivoted by hand beforehand.
