Definitions

  • Skiers shoes are generally positioned and secured on the ski through the agency of two parts, to wit, on the one hand a stirrup or abutment acting on the tip of the shoe and, on the other hand, tensioning means acting on the heel.
  • the lever controlling the tensioning means is generally arranged to the front of the stirrup or abutment and it exerts the tractional stress required on a cable passing behind the heel of the shoe in order to firmly hold the latter on the ski.
  • Said tractional stress is necessarily large and is applied on the rear side of the heel in a direction which is more or less oblique with reference to the general plane of the ski and this has several drawbacks, inter alia:
  • My invention removes these drawbacks and has for its object an arrangement which, although it does not act after the manner of conventional tensionmg means, will be designated hereinafter as a tensioning means for sake of clarity, said tensioning means holding the shoe heel on the ski, while urging the tip of the shoe into engagement with the abutment or the stirrups and allowing the release of the shoe in the case of the skier falling forwardly.
  • the engagement with the heel is obtained to this end by means of a strap which is pivotally secured to a support rigid with the ski and pivotally carries a control lever cooperating with at least one securing member the position of which is defined by at least one spring of an adjustable power.
  • a vertical stress exerted upwardly on said strap by the edge of the shoe heel rises beyond a predetermined limit value, said strap is shifted upwardly and carries along with it the control lever and the securing member, said shifting corresponding to an angular movement such that it cuts out any contact between the strap and the shoe which is consequently released.
  • a hood-shaped support rigid with the ski carries a transverse horizontal spindle to which are pivotally secured the strap engaging the shoe heel and an arm the rear end of which is pivotally coupled with a stirrup the sides of which extend through the rear surface of said support and are provided beyond said surface with threads adapt-ed to be engaged by nuts permanently engaging said rear surface of the support, while the front end of said ited States Patent M Patented Dec. E3, 1965 arm carries two projections engaging two corresponding projections on the control lever pivotally secured to the same transverse spindle as the heel-engaging strap.
  • FIG. 1 is a side elevational view of the arrangement when positioned on a ski and ready for operation
  • FIGS. 2 and 3 are, on an enlarged scale, respectively a side eilevational view and a view from above of the said. arrangement
  • FIGS. 4, 5 and 6 are longitudinal sectional views through line 44 of FIG. 3 of the said arrangement respectively in its open position, in its closed position and in its shoe-releasing position,
  • FIGS. 7 and 8 are transverse sectional views respectively through lines 7-7 and 88 of FIG. 3.
  • FIG. 9 is a side elevational view of a part of the control lever.
  • 2 designates a hood-shaped support secured to the ski and including a forward extension forming a guide 3 engaging both sides of the shoe so as to allow positioning the heel of the shoe on the ski.
  • Said support 2 carries a horizontal transverse spindle 4 to which is pivotally secured a heel grip or strap 5 of which the front end has an arcuate outline and is provided with a shoulder so as to allow it to engage the upper rear edge of the shoe heel, which edge is advantageously protected by a metal plate s.
  • a stirrupshaped member iii-l2 including two legs 12 extending rearwardly and passing freely through the rear surface of the support 2, the rear ends 13 of said legs being threaded.
  • Two helical springs lid surround coaxially the corresponding legs 12, one end of each spring bearing continuously against the rear surface of the support 2 whereas its other end engages a movable plate 15 through which the two legs 12 of the stirrup extend, said plate being held in position on said legs by two nuts 16 screwed over the threaded leg sections 13.
  • the plate 15 is also provided with an opening through which a longitudinal rod 17 extends freely, said rod being screwed into the support 2 and serving as an abutment for the arm 7 at the end of its travel, said arm 7 being urged against said abutment rod 17 by the springs i i with the interposition of the stirrup 1642.
  • abutment rod By screwing said abutment rod to a more or less considerable extent into the support 2, the position of the arm 7 when inoperative and consequently that of the projections it on the latter is modified. This allows adjusting readily the height H (FIG. 5) at which the heel is held fast by the strap 5 in accordance with the actual thickness of the shoe heel of the skier.
  • the rear end of the strap 5 engaging the heel forms a fork which provides not only for the passage and guidance of the arm 7, but also allows the passage of the rear- Wardly directed control lever 18 which is pivotally secured to the strap 5' around the horizontal spindle ll).
  • the lever 13 includes an extension directed first downwardly beyond the spindle 1'9 and then forwardly so as to form two projections 2% adapted to cooperate with the two projections 8 on the arm 7 (FIGS. 2 and 9).
  • an arrangement securing a skiers shoe heel to the ski comprising a forwardly facing hood-shaped support rigid with the ski, a transverse horizontal spindle carried by said support, a heel grip adapted to pivot around the axis of said spindle and to engage the upper rear edge of the skiers shoe, a control lever pivotally secured to said grip, a securing member directed rearwardly and adapted to pivot around the axis of said spindle, cooperating projections on the lever and on said member to operatively interengage said lever and said member, a stirrup coupled with the securing member and including two threaded legs extending rearwardly through the support, nuts fitted adjustably over said threaded legs, a plate extending over the front ends of the nuts, springs fitted between said plate and the rear surface of the support to adjust the position of the securing member through the stirrup to hold the latter in a position for which the lever holds the grip engaged thereby in its operative heel-engaging position as
  • an arrangement securing a skiers shoe heel to the ski comprising a forwardly facing hood-shaped support rigid with the ski, a transverse horizontal spindle carried by said support, a heel grip adapted to pivot around the axis of said spindle and to engage the upper rear edge of the skiers shoe, a control lever pivotally secured to said grip and adapted to be shifted between an upper inoperative position and a lower operative position, a securing member directed rearwardly and adapted to pivot around the axis of said spindle, cooperating projections on the lever and on said member to operatively interengage said lever and said member, a stirrup coupled with the securing member and including two threaded legs extending rearwardly through the support, nuts fitted adjustably over said threaded legs, a plate extending over the front ends of the nuts, springs fitted between said plate and the rear surface of the support to adjust the position of the securing member through the stirrup to hold the latter in a position
  • means for securing a skiers shoe heel to the ski comprising a support rigid with the ski, a heel grip pivotally secured to said support for vertical swinging movement about a fixed horizontal axis, means on said heel grip to engage the upper rear edge of the skiers shoe, a control lever mounted on said grip for pivotal movement relative to said grip about a horizontal axis fixed relative to said grip and spaced from said fixed horizontal axis, a securing member pivotally mounted on said support for vertical swinging movement about said fixed horizontal axis, means on said securing member engaged by said lever during operation thereof, and spring means acting between the support and the securing member.
  • a device as claimed in claim 3 and an abutment adjustably secured to the support and projecting to the front of the support to engage the securing member to define the operative position of the securing member.
