Definitions

  • the present invention relates to safety ski bindings adapted to normally retain the skiers boot on the ski and to release said boot when the lifting effort applied thereto exceeds a predetermined adjustable value, said device comprising a movable piece permitting voluntary release by means of a strap attached thereto, against the force of a compression spring.
  • the ski binding according to this invention comprises a stirrup piece pivoted to the fastening case, frame or mounting structure by means of a pair of lateral rivets adapted to move along apertures formed in said case, and that said case carries at least one stop member adapted to be engaged by said stirrup, the stirrup being also adapted to rotate by reacting against said stop, said rivets having the dual purpose of compressing said spring and releasing the boot retaining member.
  • FIG. 1 is an elevational view showing the device holding a boot on a ski
  • FIG. 2 is a section taken along the line IIII of FIG.
  • FIG. 3 is a section taken along the line IIII of FIG. 5 but in the position corresponding to voluntary boot release;
  • FIG. 4 is a section also taken along the line "-11 of FIG. 5, showing the device in a position corresponding to the automatic release of the ski binding;
  • FIG. 5 is a plan view of the device partly in cross section along line V-V of FIG. 2.
  • the ski binding comprises a hollow structure or case 1 secured to the top surface of a ski by means of a base plate 2, in the known fashion.
  • This case 1 carries a member 3 pivoted about a fixed transverse shaft 4 and carrying a fork-like piece 5 adapted to normally engage the front and top surfaces of the heel of a ski boot 6 and constituting a heel hold-down member.
  • the piece 5 is secured to the member 3 in the usual manner by means of a screw 7 such that the vertical position of the piece is adjustable as a function of the thickness of the boot sole.
  • the aforesaid member 3 is hollow like the case 1 and carries two pins 8, 9 lying along the same axis X-X' (FIG. 5), said pins being riveted to the side walls 3a and 3b of said member 3.
  • Mounted for free pivotal movement on these pins 8, 9 are a pair of cylindrical rollers 10, 11 respectively, having polished outer surfaces. In the normal skiing position these rollers rest on two edge surfaces 12 on the side walls of the case 1, one of these two surfaces being visible in FIGS. 2, 3 and'4;
  • the mo'vable member 3, as shown in FIG. 2 is prevented from being raised and thus freeing the ski boot by the action of the surfaces 13 of a pair of flat plates 14, 15 of which only one is visible in this Figure.
  • These two plates l4, 15 are adapted to pivot freely about shaft 16 fixed on the side walls of the case'l and comprises retaining means for retaining the member 3 in the boot holding down position.
  • the plate 14 is also provided with a circular hole 31 fitting freely about the body of a cylindrical rivet 17. Similarly, the other plate 15 receives therethrough a rivet 18. To the relatively large diameter of the heads of these rivets 17, 18 is secured a U-shaped member 19 pivoting freely thereabout and retaining by its central portion one end of a compression spring 20 as shown in FIGS. 2 and 5 the other end of this spring bearing against an angularly fixed flat nut 21.
  • a screw 22, pre vented by a collar or shoulder portion 23 of its head from being forced out from the case 1, is adapted to be screwed at will in said nut 21 so that the skier can adjust the compression of spring 20.
  • the rivets 17 and 18 extend through elongated slots 26 (see FIG. 1) in .the respective laterally spaced opposed side walls of the case 1 and the slots 26 are arcuate and centered about the axis of the shaft 16.
  • boot is no longer held against upward movement, and can thus move the fork-like piece 5 upwards, so as to be released.
  • a safety ski binding device comprising: a casing having laterally spaced opposed side walls; a boot holddown member pivotally mounted on 'said casing for movement between .a boot holding-down. position and a boot-releasing position; retaining me ans pivotally mounted on said side walls for pivotal movement between a first .position wherein said retaining means engages a cooperating part of the boot.
  • lipid-down member to retain the hold-down member in said boot holdtrig-down position and a second position wherein' said retaining means disengages said part of said boot holddown member and frees the boot hold-down member to pivot to and from said boot-releasing position; spring means in said casing for urging said retaining means towards the first position; a pair of generally transversely aligned shafts each passing through an aperture in each of said side walls and through said retaining means; a stirrup piece mounted on the exterior of said side walls for pivotal movement about said shafts; means mounting said shafts for movement between corresponding first and second positions relative to said aperture when said retaining means moves between its first and second positions; at least one stop member on said side walls engageable with said stirrup piece; and means mounting said stirrup piece for manual movement into engagement with said stop member followed by pivotal movement of said stirrup piece about said stop member to move said shafts from their first position to their second position.
  • a safety ski binding device according to claim 1; wherein said retaining means has a pair of cam surfaces releasably engageable with said cooperating part of said boot hold-down member to maintain the latter in said boot holding-down position.
  • a safety ski binding device according to claim 2; wherein said cooperating part comprises a pair of rollers mounted on said boot hold-down member.
