Definitions

  • My invention relates to safety securing means for skis of the so-called abutment type, wherein the front of the skiers shoe is held in position under the action of a cable, belt or the like, or of the thrust of any suitable part against an arcuate member fitted over the upper surface of the ski and the general shape of which allows the lateral release of the skiers shoe in the case of a dangerous twisting efiort exerted on the leg or foot of the skier.
  • My improved securing means is more particularly of the type wherein the abutment is pivotally secured to a statonary axis perpendicular to the plane of the ski and is subjected to an elastic thrust holding it in a normal longitudinal position, while it allows an angular shifting round said axis whenever the lateral stress exerted by the skiers shoe rises above a predetermined value.
  • My improved securing means is characterized with reference to all known securing means by the fact that the abutment member which is pivotally secured to said stationary axis or pivot, carries in its rear section two parallel spindles serving as a pivotal connection for two jaws which define an arcuate line engaged by the front end of the skiers shoe, while means controlled by an eccentric member rigid with said stationary axis are provided for holding fast the two jaws with reference to each other whenever the main pivoting abutment memher is in its normal operative position and, in contradistinction, said jaws are released when last-mentioned abutment member is shifted angularly in either direction.
  • the means serving for the locking of the two jaws when the main abutment member occupies its normal position may, of course, be designed in various manners.
  • said main abutment member is designed so as to form a slideway for a further member provided with a groove through which passes an eccentric stud fitted on the axis of the body of the abutment member, said grooved member terminating at its rear end in the shape of a wedge engaging a housing of the same outline, bounded by the two jaws, while it is subjected at its front end to the thrust of a spring urging it rearwardly, so as to hold said wedge in said housing and thereby to hold the two jaws fast, the release of said jaws being obtained only after an angular shifting of the main abutment member, which leads to a movement of the eccentric stud, vw'th a view to producing a forward sliding of the wedge-shaped end of the groove member.
  • the two jaws When released, the two jaws may furthermore assume a rocking movement in opposite directions; it is sufiicient for this purpose for the two jaws to show in their contacting areas an arcuate outline, while said areas are provided with teeth, so as to act as two interengaging pinions.
  • FIG. 1 is a perspective view of the safety system.
  • FIG. 2 is a vertical longitudinal sectional view through line 22 of FIG. 3.
  • FIGS. 3 and 4 are horizontal sectional views through line 3--'3 of FIG. 2, respectively for the normal and released position of the arrangement.
  • Said pedestal 2 designates a plate having a generally V-shaped outline and forming the pedestal of the securing means which is thus secured to the ski 3 through the screws 4 (-FIG. 3).
  • Said pedestal 2 is rigid with a vertical pivot 5 and with a longitudinal tapped sleeve 6.
  • the stationary vertical pivot 5 carries an eccentric stud 7 at its upper end, while the tapped sleeve 6 lies to the front of the pedestal 2 along the longitudinal axis of the ski 3.
  • Said sleeve carries at its rear end opening a ball 8 which is urged forwardly by a spring which is not illustrated in the drawings, since it is carried inside the sleeve, while a screw 9 engaging the front end of the sleeve allows said spring to exert a more or less considerable pressure on the ball 8 according to the extent of its screwing inside the sleeve.
  • a safety nut 10 allows holding the screw 9 fast in the desired adjusted position.
  • the ball 8 engages, as vwell known per se, a plate 12 which plays the part of a cam and is provided with at least one notch, the bottom of which is engaged by said ball 8.
  • said plate 12 is rigid with the body 13 of the main abutment member fitted over the stationary pivot 5 and provided in its upper section with a housing 14; inside the latter is slidingly fitted a plate 15,
  • the medial part of which is grooved at 16; the groove thus formed in the plate 15 is in the shape of a V and is engaged by the eccentric stud 7 rigid with the spindle 5.
  • the said plate 15 is in the shape of a wedge, while its front end is subjected to the thrust exerted by a spring 18 carried inside the housing 14 and urging the plate 15 rearwardly.
  • the body 13 of the main abutment mem ber carries two parallel vertical spindles 19 round which are pivotally secured the corresponding jaws 21 appearing in plan view as arcuate parts and vertically as angle bars.
  • the two jaws 21 define thus a comparatively long arcuate line which encloses to a large extent the entire front section of the skiers shoe.
  • said two jaws 21 are given, furthermore, the shape of portions of a cylinder in which are provided teeth 22, the teeth of one jaw meshing with those of the other jaw.
  • Said jaws 21 are lastly rigid with two studs 23 between which is fitted the wedge-shaped end 17 of the sliding plate 15 which, under the action of the thrust exerted by the spring 18 in association with the shape of the groove 16 engaged by the stud 7, allows the two jaws 21 to be held fast by the wedge-shaped end 17 in alignment with each other whenever the securing means are in their normal position of use, as illustrated in FIG. 3.
  • a safety securing system for skis comprising a pivot rigid with and perpendicular to the upper surface of the ski at a location along the longitudinal axis of the ski,
  • a safety securing system for skis comprising a pivot rigid with and perpendicular to the upper surface of the ski at a location along the longitudinal axis of the ski,
  • apparatus for use with a ski, apparatus comprising: a plate adapted for being rigidly secured to the ski along the longitudinal axis of the ski, a body, means supporting the body from the plate for rotation about an axis, a fixed stud on said means 'eccentrically located relative to said axis of rotation, said body being provided with a housing extending perpendicularly to the stud, a fiat member in said housing provided with a V-shaped groove, said stud means rotatably supporting each'of the jaws from the body, arid means on said jaws for cooperating with the flat member to lock said jaws with respect to said body with said fiat member in a first position relative to the body, said fixed stud being located in the groove at the apex thereof in said first position, said fixed stud causing sliding movement of said flat member in said housing upon angular movement of said body from said first position relative to said plate whereby said fiat member is moved to a position Whereat the means for locking the jaws is ineffective and said jaws
  • Apparatus for use with a ski comprising a plate adapted for being rigidly secured to the ski along the ported on said pivot and rotatable with respect to said plate, said body defining a housing extending perpendicularly to the stud, a fiat member slidably supported in said housing of the body, said fiat member being provided with a V-shaped groove in which is positioned said stud, a pair of jaws each being rotatably supported on said body and defining in a closed position a rearwardly facing arcuate outline adapted for engaging the toe of a skiers foot, a stud on each of the jaws cooperatively defining a space therebetween, said fiat member including a wedge-shaped end portion projecting between said studs on the jaWS with the stud on the pivot located at the apex of the groove in the plate whereby said jaws are prevented from rotating relative to the body, said stud on the pivot being effective upon relative rotation of the body and plate to cause movement of the fiat member away from the plate
  • Apparatus as claimed in claim 4 comprising means for locking the plate and body together to prevent relative rotation therebetween.
