Definitions

  • the present invention relates to ski bindings which are adapted for engaging the shoes of skiers for securingthe It is known to provide in ski bindings a dinally displaceable heel clamping jaw, the latter being connected with the tightener by a metal cable running below the sole of theshoeh In the known designs, the heel clamping jaw forms with its guiding part a rigid member. Thus, theheel clamping jaw is exclusively displaceable on the-ski, i.e., in axial direction of the ski. This results in an unfavorable stressing of the sole of the ski shoe. Moreover, it has to be considered that the rim provided on the heel clamping jaw has to fit exactly a recess in the shoe because of the rigidity of this clamping jaw. Otherwise the desired connection between binding and shoe would not be achieved at all.
  • a further disadvantage is that the clamping jaw does not automatically return to a disengaged position when the binding is released.
  • the present invention provides an extremely simple device to prevent all these disadvantages by the provision of a heel clamping jaw which is supported for displacement in a longitudinal direction on the ski behind the heel plate of the binding, and is also supported for pivotal movement.
  • the clamping jaw is actuated by a cable which is'directly which is preferably under the stress of a spring.
  • FIG. 1 is an elevational view of the binding according to the invention
  • FIG. 2 is a plan view of the embodiment in FIG. 1, and
  • FIG. 3 is an enlarged view' of the operative portions of the binding.
  • a toe support or clamping jaw 2 extending at right angles to the longitudinal axis of the ski.
  • the jaw 2 is fixed to the ski by means of two screws.
  • the face 30f the jaw 2 for receiving the toe of the shoe is recessed and limited at its top by the projecting edge 4.
  • a slightly inclined plate 5 fixed with two screws to theski serves as support for the heel of a boot.
  • the heel clamping jaw 6 is arranged behind the plate 5. Clamping jaw 6 is supported for pivotal movement from the guiding plate 8 about axis 7.
  • plate 8 is provided with two slotted holes 9 through which pass anchoring screws 10.
  • the heel clamping jaw 6 has the form of a trapezoid, the longer of the two parallel sides being provided with a rim 11 fitting the curvature of the shoe heel. Lugs 12 are pro vided at the ends of this rim. V V V
  • a tightener 13 is fastened with screws on the ski forwardly'of the toe clamping jaw, and a steel cable runs. via a spring 14 from the tightener 13 to the heel clamping jaw 6.
  • the length of the cable 15 is regulated by means of a single screw 19, whereby the force acting through the clamping jaw 6 on the heel of the shoe when the tightener is locked, can be adjusted.
  • cable 15 runs in a groove 17 below the ski surface 16.
  • the plate 5 and the clamping 3,170,7fi2 Patented Feb. 23, 1965 ently of whether it is tight or loose and thus form guiding members for the cable.
  • a spring 18 guided by the cable 15 is braced against the plate 5.
  • the cable 15 is fixed at the middle part of the clamping jaw 6.
  • the enclosed figures show the binding in an open condi- 6 is pulled forwardly .by the cable 15 and simultaneously the clamping jaw 6 is pivoted downwardly around the axis 7 to cause the rim 11 to be pressed againstthe heel of the boot.
  • the diagonally forward and downward acting force can be divided into two components, one pressing the shoe against the clamping jaw 2 and the other against the plates respectively. 'With the tightener locked, the:
  • the binding according to the invention can be used also without the groove 17.
  • the embodiment described shows that the fastening as well as the unfastening of the ski is very simple. It is unnecessary to hook a low-traction tightener and to pulla spring over the heel of the shoe. Only eight screws are required to fix the entire binding, so that the mounting is simple and can be performed without difficulty. A freezing of the movable parts is practically impossible.
  • the cable end can be fixed on the jaw 6 at different distances from the axis 7.
  • the two skis can be steered closely in parallel during use.
  • the down-pulls. provided usually for the cable at the lateral faces of the ski have a braking efiect, particularly, in deep snow. This disadvantage is prevented by the binding according to the present invention.
  • the binding according to the present invention remedies economically a hitherto obvious wardly of said toe rest and adapted to support the heel of a boot with the toe of the latter in contact with the toe rest, a guiding plate supported for free longitudinal displacement rearwardly of said heel rest, a clamping jaw supported on said guiding plate for pivotal movement towards and away from said heel rest for contacting the heel of a boot supported thereon, said clamping jaw having an initial position inclined upwardly and forwardly on said ski, a cable extending from said clamping lever to said clamping jaw for pivotally moving the latter and concurrently displacing the guiding plate upon pivotal movement of the clamping lever, said cable passing under the toe rest and heel rest and then passing beyond the heel rest directly to the clamping ,jaw along a substantially straight line,
  • said cable being fixedly secured to the clamping jaw, and an axially compressible hollow spring between the clamping jaw and the heel rest, said cable extending through said spring to exert a force on the clamping jaw to displace the same against the action of the spring when the clamping lever is pivotally moved.
  • a ski as claimed in claim 1 wherein a longitudinal groove is formed in said ski and said cable is accommodated in said groove.
