Definitions

  • a rear stop for a ski binding comprises a stop body, and a heel-engaging jaw mounted for vertical swinging movement on the stop body by a first pin.
  • a link is pivotally mounted at one end on the stop body by a second pin and at its other end is pivotally connected to the jaw by a third pin.
  • the second pin is urged forwardly by a spring, so that the third pin passes over center through the plane of the first two pins with a snap action, between open and closed positions.
  • the angle of the link in these open and closed positions can be adjusted by shifting the second pin forwardly or rearwardly; and the abutment shoulders between which the spring is compressed travel as a unit with the second pin during this adjustment, thereby to keep the spring strength constant.
  • the present invention relates to rear stops for ski bindings.
  • the object of the present invention is to meet this need by providing a rear stop for ski binding in which two pins connect hingedly the jaw for the shoe heel with the stop body and with a link respectively, said link being in turn hinged on said stop body through a pin which is out of line with respect to the two pins for the jaw and passes through an elongated hole in said stop body, said latter pin being urged by a constant force spring which tends to oppose the sliding of said pin rearwards within said elongated hole and thus the angular shifting of the link and the jaw, the disalinement angle of the thre above-mentioned pins defining the lower limit of the force required for the opening of the stop, said angle being adjustable by shifting transversely the intermediate 3,408,087 Patented Oct. 29, 1968 pin, that is, that on which the link only is hinged, the two shoulders for the above-mentioned spring movement moving together with said intermediate pin.
  • the present invention provides an arrangement for obtaining such a longitudinal thrust.
  • the body of the stop of the invention is mounted on a base plate integral with the ski, said base plate forming a slide over which said stop body is adapted to slide lengthwise, while a spring is inserted between a shoulder on the stop body and a nut on a screw on the head of which said shoulder bears when the stop is at rest but from which it moves away, while increasing the compression of said spring, when the stop is being used, the amount by which said screw is screwed in said nut defining the amount of compression of said spring and thus the amount of the thrust exerted on the shoe by the stop.
  • the screw which receives said nut passes rearward through a lug integral with the slide-forming base plate for the stop body, and on either side of said lug said screw receives a nut and a check nut respectively, which enables said screw and thus said stop o be given the longitudinal position wanted.
  • the rear stop of the invention includes means for the controlled release thereof when the user wants to take oif his skis.
  • the heel-retaining jaw of said stop has a rear extension in the shape of a lever pivotally secured to the stop body by the same pin as said jaw, which lever carries two flanges provided with two curvilinear slots facing each other, through which the fingers of a nut pass.
  • the threaded shoulder of a rod is screwed adjustably in said nut, said shoulder acting as a bearing for the spring controlling the opening and closing operations of the jaw, which spring is guided by said rod.
  • the shape of the slots in the flanges of said lever is such that, depending on the position given to said lever, said screw is allowed or not allowed to move back and thus to permit or prevent the opening of the stop.
  • FIGURES l and 2 are perspective views of said rear stop, in closed condition and in open condition respectively;
  • FIGURE 3 is a longitudinal section of same in its open position
  • FIGURE 4 is a cross-section along line 4-4 of FIG- URE 3;
  • FIGURES 5, 6, 7 are diagrammatic figures illustrating the arrangement and the operation of the device enabling the user to take off his skis.
  • 2 indicates a base plate secured to the ski and acting as a longitudinal slide 3 for the stop body 4.
  • the lower portion of said body 4 houses longitudinally a helical spring 5 which is in compressed condition between an annular bearing 6 on the body 4 and a nut 7 screwed on a screw 8 which passes through the bearing 6, the spring 5 and the nut 7.
  • Said screw 8 is provided with a head 9 which, when the stop is at rest, bears on the front surface of the bearing 6.
  • the nut 7 is adapted to move longitudinally inside the stop body 4, but not to rotate therein, so that, by rotating the screw 8, it is possible to vary the amount of compression of the spring 5 and thus the thrust of said spring on the annular bearing 6 on the stop body 4.
  • the rear end of the screw -8 passes through a vertical lug 10 integral with the base plate 2.
  • the screw 8 On either side of said lug 10 the screw 8 is provided with a nut 13 adapted to rotate freely, and with a check nut 12 respectively. After loosening the nut 13 and the check nut 12, it is possible to move the screw 8 longitudinally and thus to shift the stop body 4 backward or forward over the base plate 2.
  • the upper portion of the stop body 4 carries a horizontal pin 14 on which the jaw proper 15 and a lever are pivotally mounted, said lever forming a rear extension of said jaw 15.
  • the jaw 15 is provided with two horizontal wings, 15a, 15b respectively, adapted to grip around the protruding end of the shoe heel.
  • the upper wing 15b is adjustable to allow setting the spacing between the two wings 15a, 15b, according to the thickness of the shoe heel.
  • Said jaw 15 is pivoted not only on the stationary pin 14 but also on a pin 16 carried by a link 17 which is pivoted on a pin 18 the ends of which pass through two horizontal elongated slots 19 provided in the lateral surfaces of the stop body 4.
  • the central portion of said pin 18 is in the shape of a shoulder 21 through which a rod 22 passes freely, the rear end 23 of said rod extendin beyond the rear surface of the stop body 4.
  • a helical spring 24 is guided by the rod 22, the ends of said spring bearing on the shoulder 21 and on a further shoulder 22a on said rod 22 respectively.
  • the rear extension of said shoulder 22a is threaded and carries a nut 25 provided with two coaxial fingers 26.
  • Said fingers 26 pass through two elongated slots 27 facing each other which are provided in the two flanges of the lever 20 pivoted on the same pin 14 as the jaw 15. Said lever 20 is continually subjected to the action of a spring 28 which tends to keep it in its uppermost position, that is, in the position illustrated in FIGURES 3, 5 and 7.
  • Each elongated slot 27 has the curvilinear outline shown in FIGURES 5-7, that is, each slot comprises two portions meeting at an angle.
  • FIGURES 1 and 5 the rear stop of the invention is shown in its normal position of use, in which the heel of the skiers shoe is firmly applied to the ski by the jaw 15, the latter being subjected to a vertical downward thrust by the pin 16, the link 17, the pin 18 and the spring 24. Screwing or unscrewing the rod 22 in the nut 25 makes it possible to shift said rod axially together with the shoulder 21 which is held against the bearing 22b by the spring 24, which results in a corresponding shifting of the pin 18 and thus a variation of the angular position of the link 17.
  • a rear stop for a ski binding comprising a stop body adapted to be mounted on a ski, a first pin carried by the stop body, a heel-engaging jaw mounted for vertical swinging movement on said first pin, a second pin extending through and movable lengthwise of elongated slots in said stop body, a link mounted for vertical swinging movement on said second pin, a third pin pivotally interconnecting said link and said jaw, said second pin being disposed rearwardly of said third pin and said first pin being disposed rearwardly of said second pin, a spring continuously yieldably urging said second pin forwardly whereby said third pin passes over center of the common plane of said first and second pins with a snap action to define open and closed positions of said jaw,'a pair of abutment shoulders between which said spring acts, and means for moving said second pin and said abutmentshoulders together as a unit forwardly or rearwardly thereby to alter the angle that said link makes with said common plane in said open and'closed positions while at the same time maintaining constant the strength of
  • a rear stop as claimed in claim 2 said plate having an integral lug through which said screw passes, a nut on said screw on one side of said lug and a check nut on said screw on the opposite side of said lug whereby said screw and stop body may be shifted longitudinally relative to said plate.
  • each of said flange slots having portions disposed at obtuse angles to each other.
  • a rear stop as claimed in claim 4 and a shoulder that slidably encircles said rod, the other said abutment and said second pin being carried by said shoulder.
