Definitions

  • the invention relates to a heel holder for safety ski bindings with a base plate which is displaceably guided on a ski-fixed guide rail against the force of at least one thrust spring and which supports a bearing block, on which bearing block a sole holder is pivotably arranged, which is supported on one side on a control surface on which on the other side, a pawl which is acted upon by a spring which is arranged in a pivotably mounted spring housing is held in the downward position.
  • a heel holder of the type mentioned at the outset is, for example, in the technical manual TECH60 from Tyrolia-Freizeitella Gesmb H & CO, page 28; appeared in 1979.
  • This heel holder has proven itself in practice and is comfortable to use for the user, but has the disadvantage that when the toe is released, for example in the event of a lintel fall, the sole holder remains closed, so that the skier can put on the binding again this must be opened by hand using a release lever.
  • the invention is therefore based on the object of further developing a heel holder of the type mentioned at the outset, so that it is ready for entry even after the toe piece has been triggered.
  • At least one control part is attached or articulated to the ski-fixed abutment of the thrust spring (s), which passes through a recess in the base plate and softer when the thrust spring (s) is released without heel release of the spring housing from its support surface on the pawl pushing away.
  • the goal set is achieved perfectly.
  • the heel holder is moved towards the ski tip by relieving the thrust spring (s), while the control part remains effective.
  • the control part is pressed away from its support surface on the pawl.
  • the pawl is thus free from the control surface of the bearing block, so that the sole holder can pivot into the open position; the heel holder is ready to step on.
  • control part on the ski-fixed abutment can be swung up in the region of an acute angle away from the ski plane and is held in its rest position by a return spring, which is preferably a leg spring. In this way, the friction occurring between the spring housing and the control part is effectively reduced.
  • each control part has a control lug, which comes to rest when the heel holder is closed, both in the relaxed and in the pretensioned position of the thrust spring (s) in one detent depression of the spring housing, which detent depressions are arranged one behind the other in the longitudinal direction of the ski and between which locking recesses a control cam pointing in the direction of the top of the ski is provided.
  • One locking recess ensures an unimpeded closing of the heel holder even without a ski boot inserted, the second serves to hold the control part when the ski boot is inserted into the binding.
  • the control cam arranged between these locking recesses is acted upon by the control lug of the control part when the front jaw is triggered only, whereby the spring housing is raised and is released from its support surface on the pawl.
  • ski-fixed abutment as is known per se, is formed by a fork which, in a manner known per se, has a web on one end for supporting the thrust spring (s) and on the other hand with a or unlocking is provided with the guide rail provided, and that the control part (s) is or are attached to the legs of the fork.
  • a fork which, in a manner known per se, has a web on one end for supporting the thrust spring (s) and on the other hand with a or unlocking is provided with the guide rail provided, and that the control part (s) is or are attached to the legs of the fork.
  • FIG. 1 shows the heel holder according to the invention in a side view in section in the closed position without a ski boot inserted
  • FIG. 2 shows the locking mechanism of the heel holder in an enlarged scale also in a side view in section in one Position without inserted ski boot
  • FIG. 3 shows the locking mechanism similar to FIG. 2 but in its position with inserted ski boot
  • FIG. 4 shows a position of the locking mechanism during a safety release of the toe (not shown)
  • FIG. 5 shows a second embodiment in a similar way Representation as in FIG. 2.
  • a guide rail 2 is fastened to the top of a ski 1 by means of screws (not shown).
  • a base plate 3 of the heel holder is displaceably guided in the longitudinal direction of the ski 1 and, in a manner known per se, can be locked in the desired position in order to adapt the binding to ski boots of different lengths.
  • a thrust spring 5 is arranged in a recess 3a of the base plate 3, one end of which is connected to a support part 3b the base plate 3 and the other end thereof is supported on a crossbar of a fork serving as a ski abutment 6, which overlaps the edge of the recess 3a by means of two indicator pins 6a.
  • the heel holder is thus guided against the force of the thrust spring 5 on the guide rail 2.
  • the indicator pins 6a are used in connection with a scale located on the base plate 3 when the ski boot is inserted into the binding for reading the contact pressure of the heel holder against the toe (not shown).
  • the abutment 6 has two legs 6b extending to the side of the thrust spring 5 and parallel to the longitudinal axis of the ski 1, which are designed in the end of the cutout 3a of the base plate 3 facing away from the transverse web of the abutment 6 to form a locking tongue, which are known and therefore not shown way is provided for locking the heel holder on the guide rail 2.
  • At least one of the two legs 6b of the abutment 6 carries a control part 10, which passes through the cutout 3a of the base plate 3 from below and the shape and mode of operation of which will still be discussed.
  • a bearing block 7 On the base plate 3, a bearing block 7 is attached, on which a sole holder 8 is pivotally mounted about an axis 9.
  • the sole holder 8 carries on a further, parallel to the first-mentioned axis 11 also a pivotable pawl 12, which engages under the catch 17a of a control surface 17 formed on the bearing block 7 in the down position of the heel holder by means of a detent 12a.
  • an approximately U-shaped spring housing 13 is mounted on the pivot axis 9 of the sole holder 8 and has longitudinal slots 13 a in its two side cheeks, which form a guide for a locking part 14.
  • the locking part 14 is acted upon by one end of a release spring 15, the other end of which is supported on a spring abutment 16 which is adjustable in the axial direction of the release spring 15 by means of a screw 28 rotatably mounted in the spring housing 13.
  • the pawl 12 forms a catch 12b for the locking part 14, into which it is pressed by the release spring 15.
  • a recess 12c is provided on the pawl 12, which serves as an exemption and into which the locking part 14 engages when a release lever 18 is actuated.
  • the release lever 18 laterally overlaps the sole holder 8 and is pivotally mounted on the axis 11 arranged on the sole holder 8, on which axis 11 the pawl 12 is also articulated.
  • a bolt 19 is mounted parallel to the axis 11 on the release lever 18, passes through both the sole holder 8 and the side walls of the spring housing 13 and is slidably guided in each of these two components in elongated holes 8b, 13b.
  • the two elongated holes 8b provided on the sole holder 8 are arranged concentrically to the pivot axis 11, the two elongated holes 13b formed on the spring housing 13 are arranged approximately at right angles to the longitudinal extension of the elongated holes 8b of the sole holder 8.
  • the bolt 19 slides upward in the elongated holes 8b of the sole holder 8 and pivots while simultaneously sliding in the elongated holes 13b of the spring housing 13 in the direction of the ski tip, this also around the axis 9 upwards.
  • the locking part 14 disengages from the catch 12b of the pawl 12, whereby the pawl 12 can pivot freely and its catch 12a is released from the catch 17a of the control surface 17 of the bearing block 7, the sole holder 8 swivels, supported by one on the axis 9 arranged opening spring 20, in the open position.
  • the control part 10 fastened to the leg 6b of the abutment 6 has a control lug 10a which comes to rest in the closed position of the sole holder 8 and when the ski boot is not inserted in a recess 13c in the associated side wall of the spring housing 13.
  • This locking recess 13c is formed on the lower edge of this side wall (see FIG. 2).
  • the heel holder is displaced in the direction of the toe piece by the relaxing thrust spring 5 on the guide rail 3.
  • Hiebei acts on the control lug 10a of the control piece 10 between the two locking recesses 13c, 13d formed control cam 13e of the spring housing 13 and presses the spring housing 13 upwards and. between the extent that is required to lift the locking part 14, which is mounted in the spring housing 13, out of the catch 12b of the pawl 12 (see FIG. 4).
  • the pawl 12 is no longer acted upon by the release spring 15.
  • the opening process of the sole holder 8 is supported by the opening spring 20 in the manner already described, which also takes place during the arbitrary opening.
  • the heel holder is ready for boarding, the re-entry into the binding is carried out in a manner known per se either by closing the release lever 18 and then swiveling the sole holder 8 down with the ski boot, or by first pivoting the sole holder 8 and then the release lever 18.
  • the control part shows a modification of the design of the control part 10 according to FIGS. 1 to 4 10 'according to FIG. 5.
  • the control part 10' is pivotably articulated on an axis 10'b mounted on the leg 6b of the abutment 6 away from the ski plane in a region limited by a stop, not shown, and by a leg spring 21 in it Figure shown location held.
  • the control part 10 ' engages with its control lug 10'a in the rear latching recess 13c of the spring housing 13.
  • This position corresponds to that of FIG. 2 of the first exemplary embodiment, in which the heel holder is shown without a ski boot inserted.
  • This embodiment is more favorable in terms of friction than that of the first exemplary embodiment, because the pivotable mounting of the control part 10 'reduces the friction occurring between the spring housing 13 and the control part 10' (rolling friction instead of sliding friction).
  • the invention is not restricted to the exemplary embodiments shown.
  • a large number of heel bindings, the power pack of which acts on a control surface and can be pressed away from it, can be provided with the control part according to the invention with little effort. It is also a matter of course to provide two shear springs instead of one.
