Definitions

  • the invention relates to a ski binding which is adapted to be fastened to a ski for securing the ski boot which comprises a housing and a release means which in response to excessive load or pressure releases against spring tension and frees the ski boot.
  • U.S. Patent No. 3,378,271 that the housing which carries the sole retainer, the pressure spring and the release means are pivotally connected as an assembly unit to a base plate or the like which is to be secured to the ski, that furthermore there is a joint connection between the release means and the housing and that the joint location is at a distance from the location where the unit is linked to the base plate or the like.
  • the aforementioned unit, or the housing is mounted at its end remote from the sole retainer for displacement with respect to the base plate, or the like, and is supported thereon.
  • the present invention concerns im rovements of the arrangement in accordance with the earlier disclosure, particularly in that it is constructed as a heel release which engages the ski boot at the heel.
  • this binding is to be constructed in such a manner that it remains in position after release and is returned to the position of use only by hand or by inserting and stepping down on it with the ski boot.
  • the distance between the sole holder and the step surface is to be increased for the release position while keeping the dimensions of the safety binding approximately the same.
  • the housing which is mounted on the base plate or the like for displacement in the longitudinal direction of the ski is secured against rising up of its rearward end from the base plate and that a latching device is provided which fixes the binding in open position and which is releasable by hand or by means of a foot step.
  • the latching device it is insured that either after a fall that causes the release or by manual fixing or setting, or setting by means of the ski pole, the binding components will retain the release position for the inserting of the ski boot.
  • the securing of the rearward end of the housing against raising or upward swinging from the base plate prevents the unit from swinging about its joint connection at the base plate in the direction toward the forward end or point of the ski; as this would either make it impossible, or at least ditiicult in a ski safety binding of this type to introduce the ski boot in the binding.
  • the sole retainer that engages the heel of the ski boot is disposed on the release means, for example, a pivotal or swinging member.
  • the stepping surface which is engaged by the sole of the heel is provided on the housing.
  • the mouth or opening width of the binding in the released position is substantially increased with other outer dimensions remaining the same, and thus the inserting of the boot is facilitated.
  • the joint or linking place is located between the binding and the base plate approximately at the level and behind the joint location of the release device of the housing.
  • FIG. 1 is a schematic side view of an automatic heel release device in accordance with the invention
  • FIGS. 2, 3a, 3b, 4a, 4b are fragmenntary views of different possible modifications of the latching means
  • FIG. 5 is a longitudinal section of a different embodiment of the invention.
  • FIG. 6 is a view of some of the structural components of the embodiment of FIG. 5,
  • FIGS. 7 and 8 illustrate the arrangement in accordance with FIGS. 5 and 6 schematically in the retaining and release position and FIG. 9 shows a further embodiment of the invention.
  • the housing 1 is mounted for displacement longitudinally of the ski on a support such as the plate 2 which may be a mounting plate, or also on the ski surface.
  • the automatic heel release device comprises essentially the housing 1, the pressure spring (not shown) and the release means which in this example is in the form of a lever arm 3.
  • the device is linked by means of the lever to the axle A1 presented by the base plate, particularly the side checks 5 thereof.
  • the lever is pivota'ble with respect to the housing about the axle A2.
  • the housing 1 can swing in the direction of the stepping force as indicated by arrow A about the axle A1. or swing upwardly with its rearward part about axle A1.
  • the upwardly extending cheeks 5 of the base plate 2, or the like are provided with horizontally extending slots 6 in which the bolts or pins 7 of the housing are received and are displaceably guided.
  • FIGS. 3 and 4 show arrangements for this where the spring 9 in accordance with applicants aforementioned disclosure Patent No. 3,378,271 acts by way of an abutment surface, for example, a sleeve 10 encompassing the end of the spring on a flattened surface of a bolt 11 of the lever 3. The bolt 11 is secured to the lever 3 for rotation therewith.
  • the spring 9 in accordance with applicants aforementioned disclosure Patent No. 3,378,271 acts by way of an abutment surface, for example, a sleeve 10 encompassing the end of the spring on a flattened surface of a bolt 11 of the lever 3.
  • the bolt 11 is secured to the lever 3 for rotation therewith.
  • the bolt 11 is also provided with a cut-out 13 which defines an angle with the remaining part 11a of the surface.
  • the abutment edge 14' of these two surfaces is disposed in the latched position at the level or below the axis A2.
  • the surface 13 remains in this latching position under the effect of the spring 9 in the position indicated in FIG 4b.
  • FIGS. to 8 A further embodiment of the invention is illustrated in FIGS. to 8.
  • a latch hook 17 is disposed between the pressure spring 9 and the rocking member 3 which corresponds to the lever arm 3 in FIG. 1.
  • This latch hook is linked to the base plate 2, respectively its lateral cheeks 5 at 18.
  • the hook 17 is not only at latch element, but by virtue of its cut out 19 which is engaged by spring 9, it replaces the sleeve in the embodiments described above.
  • the hook 17 extends with its projection or nose 20 over the linking connection A2 on the housing of the rocking element 3. In this manner the rocking lever 3 and the housing 1 are latched against rearward and upward rocking or swinging, except when the release pressure or force becomes so great as to overcome the resisting force of spring 9.
  • the side jaws 5 of the base plate and the release member or lever 3 extend into the housing 1 and are pivotally connected with one another at pivot joint A1.
  • all parts forming an assembly unit are encased and protected against snow and ice.
  • the arrangement is such that the contact lever 22 is connected to the common pivot axis A2 of the parts 1, 3 and provided with pins 23.
  • the lever rocks about the axis A2, whereby the pins 23 turn the latch member 17 clockwise against the pressure of the spring 9.
  • the nose or lug 20 frees axle A2 and the lever portion 3 is enabled to rock or swing together with housing 1 upwardly and rearwardly about the axle A1.
  • FIGS. 7 and 8 illustrate schematically the arrangement and position of the essential parts of this embodiment in the latched position (FIG. 7) and in the release position (FIG. 8) and where for greater clearness the contact lever 22 and the latch blade or hook 17 are omitted, while the housing is shown in dot and dash lines.
  • the amount a is inserted by which after release the housing 1 as well as the lever 3' are displaced horizontally to the rear.
  • the position of the pivot axis A2 is indicated in brackets in the retaining position in accordance with FIG. 7.
  • the sole retainer 16' here is no longer on the housing but on the release member 3' (see also FIGS. 5 and 9), while the stepping plate 15 is still secured to the housing as before.
  • FIG. 9 shows a rearwardly extending lever 3" similar to the arrangement in accordance with FIG. 1. Only in the embodiment of FIG. 9 the sole retainer 16 is secured to the lever 3" as in FIGS. -8 and the pivot connection A1 is approximately at the level and behind the pivot connection A2.
