Definitions

  • This invention relates to a safety device for anchoring the heel portion of a ski boot in a ski binding wherein the toe clip or clamp portion may be of known type. It is an object of this invention to provide for the skier a high safety of a degree heretofore unobtainable.
  • Another object of the present invention is to provide a device for anchoring the heel portion of a ski boot which is highly eflicient in use, simple to install and to operate, and economical from the viewpoint of manufacture.
  • a number of ski bindings are known in which safety means for releasing the ski from the boot under torque strain are provided on the toe; usually ski bindings of conventional type are not provided with a safety device which enables forward and upward displacement of the heel of the boot, while those bindings which allow for suitable displacements are rather complex in their construction and operability, e.g. for the purpose of transmitting remote strain by resilient means adapted to secure the heel of the boot. Consequently release devices heretofore proposed are rather complicated and the strapping of a ski is not so quick as would be desirable.
  • I provide a device which is biased in a heel-gripping sense by an operating lever controlled by a toggle spring, which, if overcome by a certain amount of force exerted upon the heel gripper, releases the boot; consequently the device operates as a safety device for forward flexures of the skiers foot.
  • the heel gripper includes a double bracket on one side of which there are pivotally mounted two hollow frustoconical rollers adapted to engage the heel of the skiers boot.
  • the hollow rollers are pivotally mounted on the bracket with their facing narrower ends separated by the central leg of the bracket; the opposite legs of the double bracket are pivotally connected with one end of a rod, preferably a threaded bolt, whose other end is slidably supported by a ring aflixed to the operating lever and are also connected with a substantially upright two-part stem which is fastened to a base plate while being movable through a small angle from a released to a secured position.
  • connection between the stem and the operating lever advantageously is a toggle linkage including a compression spring which surrounds the aforementioned bolt and is compressed between said ring and a nut which is mounted on the threaded end of the bolt. The nut bears against the adjacent end of the spring for properly loading the same.
  • the releasing force may be adjusted by vertical adjustment of the upper portion of said standard which is hollow and internally threaded at its lower end, to receive the threaded upper end of the bottom portion of the stem Whose head is held pivotally affixed to the ski by the base of the device.
  • the adjustment is effected by means of a knurled ring integral with the bottom part of the stem which may be rotated to alter the positioning thereof relative to the upper stern part.
  • FIG. 1 is a perspective view showing the binding device according to the invention.
  • FIG. 2 is a side elevation partly in section of the device shown in FIG. 1.
  • the binding device includes an operating lever 1, formed from a metal sheet, which has two side walls 2, 3.
  • the operating lever 1 is pivotally connected at 4 to a base plate 5 to be secured to the skirunner.
  • a ring 6 Between the side walls 2 and 3 of the operating lever 1 there is pivotally mounted at 7 a ring 6 in which there is slidably mounted a threaded bolt 8 having a head 9 engaging the ring 6.
  • the bolt 8 is surrounded by a compression spring 10 whose tension may be adjusted by means of a nut 11 which bears upon a washer 12 and, thereby, upon the spring 10.
  • the threaded bolt 8 extends at its front end with a flat portion 8', which is pivotally mounted on pivot pin 8" to the upper stem portion 13 whose bottom end is hollow and threaded as shown at 13'.
  • the upper stem portion 13 receives the upper end of the bottom portion 14 of the stem which may be inclined by small angles from the vertical position as seen in the drawing.
  • the knurled ring 15 integral with the bottom portion 14 of the stem is operated to adjust the elevation of the upper stem portion 13.
  • the bottom portion 14 has a head 16 connected to the base 5 which is provided with a suitable swivel housing 14' surrounding said head 16.
  • the head 16 rests upon a washer 17 and, through it, upon a rubber pad 18 which is carried by the plate 19.
  • the device comprises: slots 26 and racks 27 for periodical adjustment and for securing it to the ski runner, abutments 28 for the heel of the boot and a link 29 for a safety belt (not shown).
  • the reversed moment urges the lever 1 in its clockwise direction while pushing the rollers 23 against the heel of the ski boot so as clampingly to engage it.
  • the skier should lift the heel, e.g. for a sudden stop of the runner the two rollers 23 gripping the boot 30 are rocked with the heel and cause the bracket 21 to rotate about the axes 8" to compress the spring 10, thereby canceling the clamping action of the rollers 23 whose path diverges from the path followed by the heel of the boot; it will be seen that the heel-gripping extremity 23 of bracket 21 is positioned below its horizontal pivotal axis 8" so that the heel cannot be raised without concurrent rearward displacement of the top of the stem portion 13 to which this bracket is hinged.
  • a heel-clamping assembly comprising an operating lever pivotally secured to said base plate rearwardly of the boot of a skier, universal swivel means on said base plate between said lever and said boot, an upstanding stem tiltably secured to said base plate by said swivel means, a resilient connection between said lever and the top of said stem, and a heel-gripping member hinged to the top of said stem for swinging motion about a.
  • said member being provided with a heel-engaging extremity forwardly of said stem and below said axis, said lever being displaceable between a released position and an operating position in which said connection resiliently urges the top of said stem forwardly while maintaining said extremity in clamping engagement with the heel of said boot.
  • said stem includes a lower portion rotatable on said swivel means and an upper portion threadedly engaged by said lower portion for adjusting the elevation of said axis by rotation of said lower portion.
  • connection comprises a toggle linkage including a rod pivoted to said stem, a ring traversed by said rod and pivoted to said lever, and a compression spring surrounding said rod while bearing upon both said rod and said ring.
  • said member is a bracket with three projecting legs at said extremity and with a pair of rollers journaled between said legs for rolling contact with said heel.
  • rollers are substantially frust'oconical and face each other with their narrower ends across the middle one of said legs.
