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 and which housing carries on a transverse axis a unit consisting of a step spur and a hold-down part, which is under the influence of at least one leg spring which tries to pivot it upwards, to which unit is assigned a release lever equipped with a control cam assigned to the locking pin.
  • the heel holder of this non-pre-published type (DE-A-3 104 633) 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 toe of the ski binding, the release lever, the was formed in one piece with the step spur and the hold-down part, had to be pivoted by hand into the entry position to re-enter the ski boot.
  • FIG. 306 591 Another embodiment of a heel holder is shown in AT-PAS-306 591.
  • the release lever is fastened to a shaft which is mounted in the housing and is provided with a flattened portion, and the unit comprising a step spur and hold-down part, which swings the unit upwards from one seeking torsion spring is pivotally mounted on an axis in the housing.
  • a piston loaded by the detent spring rests on the flattened portion of the shaft.
  • the trigger lever is U-shaped and has control cams on its front that work with rollers on the unit.
  • This heel holder also has the disadvantage that it remains in the driving position in the event of an involuntary triggering of the toe piece.
  • the invention aims to eliminate the disadvantages of the known embodiments and to create a heel holder according to the type specified above, which is ready for the entry of the ski boot after any type of triggering, but on the other hand is extremely simple in its construction. Furthermore, when boarding, a relative movement between the unit consisting of the tread and hold-down part and the release lever should be possible, but in the driving position, such a relative movement, which can lead to wear of the joints, should be prevented.
  • the unit which preferably rests in the driving position along a separation plane on the release lever, is articulated to the release lever pivotable about the transverse axis of the housing and is under the influence of at least one compression spring which separates the unit from the Trying to push the transverse axis or away from the release lever, and that the unit with the release lever in the travel position is locked by means of an extension which snaps into a recess.
  • At least one hinge plate is provided for the articulated connection of the unit to the release lever, the recess of which the transverse axis of the release lever is designed as an elongated hole, whereas the transverse axis of the unit has a bore penetrates in the hinge axis, and when the or each compression spring is accommodated in a blind hole in the release lever.
  • the invention further provides that the axis of the blind bore is aligned with the axis of the hinge plate in the driving position of the heel holder and which is designed in its front region in accordance with the cross section of the hinge plate and allowing its pivoting movement.
  • this measure ensures that the unit moves away from the release lever even if the heel holder is dirty or contaminated by ice crystals.
  • the transverse axis for the release lever is mounted in bearing eyes in the latter, which are attached to the release lever and protrude laterally into recesses in the unit via the parting plane between the unit and the release lever. This also improves the latching caused by the approach.
  • the invention provides that in order to limit the combined movement of the unit or the joint plate relative to the release lever, stop surfaces are arranged on the latter. Through this the swivel angle the unit is limited to approximately 36 ° and that of the link plate to approximately 72 °.
  • leg spring which should bring about the pivoting movement of the unit relative to the release lever. It has proven to be structurally particularly simple, however, if, in a further embodiment of the invention, the or each leg spring is mounted on the transverse axis for the release lever, one leg of the leg spring being supported on a stop surface of the release lever, the other leg, on the other hand, being bent End is housed in a slot-like recess of the unit. 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 a longitudinal section and FIG. The same in the driving position, likewise in a longitudinal section, FIG. 3 shows a detail of the heel holder in the driving position in section along the line 111-111 in FIG. 4 and FIG. 4 shows a section along the line IV-IV in Fig. 3 again.
  • 1 and 2 denotes a ski, on the top 1a of which a guide rail 2 is fastened.
  • 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.
  • Housing 5 is rotatably mounted on a vertical axis 6.
  • the housing 5 has two bearing eyes 5 ′ on the side facing the ski boot, in which a transverse axis 7 for a release lever 8 is arranged.
  • This carries on its underside a control cam 9, which is assigned to the locking pin 10 or the like, which is acted upon by the locking spring 4 and is guided in the housing 5 so as to be displaceable 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 with the release lever 8 is brought about by an articulated bracket 16, the recess 16 'of which the transverse axis 7 passes through is formed as an elongated hole, whereas the transverse axis 17 of the unit 13 passes through a bore 16 "of the articulated link 16.
  • 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 guided properly in the bore 8 ′′, irrespective of whether the joint plate, as shown in FIG. 4, has a circular cross section or is also made from a flat steel with a rectangular profile.
  • 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 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 has a shoulder 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. Finally, 8 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. This is approximately 36 ° for the unit 13, but 72 ° for the joint plate 16.
  • the function of the heel holder according to the invention is as follows: in the driving position of the heel holder, the unit 13 is pressed firmly against the release lever 8 by means of the front jaw of the ski binding against the force of the springs 14, 15, so that both parts touch along the parting plane 18 (cf. Fig. 2). If the heel holder is triggered arbitrarily, the release lever 8 is pivoted out of the driving position about the transverse axis 7 against the upper side 1a of the ski. The locking pin 10 slides along the control curve 9 of the release lever 8, the locking spring 4 in the housing 5 being compressed somewhat at the same time.
  • the unit 13 becomes under the influence of the two. Leg springs 14 pivoted clockwise in FIG. 3. 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, shifts the latter due to its elongated hole 16 '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.
