Definitions

  • the present invention relates to a base plate for ski binding pivotally mounted on the ski around a vertical pivot and equipped with guide means for retaining the plate against the ski while allowing its rotation.
  • Underfoot plates are known for plate security fasteners, consisting of two parts that can be moved relative to one another so as to allow the distance between the means for holding the anterior end of the worn shoe to be modified. by one of the parts and the heel holding means carried by the other part, to adapt the binding to the length of the shoe.
  • one of the parts of this plate generally the front part, must move relative to these guide means.
  • These prior guide means consist of a horizontal surface fixed to the ski under which is engaged a corresponding horizontal surface of the plate.
  • the distance between its guide points can vary on the order of 5 mm.
  • the object of the invention is to eliminate dangerous stresses by making the guide means suitable.
  • the ski binding according to the invention is characterized in that the guide means consist of a plate mounted to slide along the axis of the ski, under a part fixed to the ski, and whose opposite edges transverse to the ski are engaged and slide in grooves of the plate.
  • the vertical forces on the holding means are thus distributed on the two sides of the sliding plate. There is no longer any moment on the underfoot plate and on the part fixed to the ski and the traction force exerted on this part is always equal to the traction exerted on the holding means.
  • the sliding plate easily supports all bending forces.
  • the construction according to the invention not only makes it possible to eliminate dangerous stresses, but also makes it possible to enormously increase the range of adjustment in length of a fixing to plate in two parts. Therefore, when the ski changes user, it is no longer necessary to move the guide means fixed to the ski, that is to say to make new holes in the ski.
  • the construction according to the invention is not only advantageous in a fixing with a sub-foot plate of fixed or adjustable length, but also in a fixing of a new type with a telescopic plate which will be described later.
  • the binding shown comprises a plate 1 pivotally mounted on a ski 2 around a pivot 3.
  • the plate 1 comprises a fixed part 4 coming from one piece with a fixed jaw 5 at its end for holding the front part of a shoe 6, and a movable part 7 carrying, at the rear, a heel piece 8 for maintaining the heel of the shoe 6.
  • the fixed part 4 of the plate is here made of light alloy and it is provided with a steel plate 9 having a longitudinal rectangular cutout 10 whose long sides are provided with a toothing 11 and 12.
  • This toothing is in engagement with the teeth of a rider 13 pivotally mounted on the cylindrical part of a cylindrical support 14 fixed to the ski 2.
  • the rider 13 is held on the support 14 by a screw 15.
  • the toothed rider 13 and the toothed cutout 10 make it possible to adjust the length between the pivot 3 and the front jaw 5, that is to say to adjust the length of the binding according to the length of the shoe.
  • the movable part 7 of the plate extends over and under the fixed plate 4. Its upper part tapers down to near the jaw 5, so that the shoe 6 rests only on this part 7 of the plate.
  • Part 7 of the plate extending under part 4 serves for the vertical retention of this part 7 which has a horizontal slot 16 into which the toothed plate penetrates 9.
  • Part 7 also has a cutout 17 allowing, firstly, the longitudinal displacement of the plate relative to the pivot 3 and, secondly, access to the screw 15 for adjusting the length of the fastener.
  • FIG. 3 it can be seen that the support 14 is fixed to the ski by means of two screws 18 and 19.
  • the fixed part 4 of the plate is held vertically by a metal plate 20 of shaped general rectangular whose edges 20a and 20b transverse to the ski are slightly raised obliquely and in the form of circular arcs centered on the axis of the pivot 3. These raised edges 20a and 20b are engaged in grooves in part 4 of the plate and can slide in these grooves.
  • the plate 20 is itself retained by a bridge 21 fixed to the ski by two screws 22 and 23 ( Figures 3 and 4).
  • the movable part 7 of the plate is also held vertically and guided by a metal plate 24 having two vertical edges parallel to the axis of the ski 25 and 26 and two sides transverse to the ski 27 and 28 whose edges are raised, in arcs of a circle centered on the axis of the pivot 3 and engaged in grooves in part 7 in which they can slide during the pivoting of the plate.
  • the plate 24 is held vertically by a plate 29 having two levels, one of which extends over the plate 24. This plate 29 is fixed to the ski by means of four screws 30, 31, 32 and 33 passing through spacers holding the plate 29 away from the ski.
  • the screws 32 and 33 and their spacers pass through the plate 24 through two oblong cutouts 35 and 36 so as to allow the plate 24 to move axially.
  • a metal plate with a low coefficient of friction 34 is arranged to facilitate the movement of the plate 24.
  • the plate 29 has a cutout 37 through which the rear raised edge 27 of the plate 24 passes.
  • the plate 29 carries two stops 38 and 39 arranged on each side of the longitudinal axis of the binding and symmetrically to this axis.
  • the front edge 40 of the cutout 37 serves as a stop for the plate 24.
  • the heel piece 8 comprises a body 41 pivotally mounted on the movable part 7 of the plate by means of a vertical pivot 42.
  • This heel piece includes a jaw 43 articulated on the body 41 around an axis 44 to hold the heel of the shoe .
  • This jaw 43 is held resiliently by means of a spring 45 acting on the jaw 43 by means of a double lever system 46/47 and a piston 48.
  • the lever 47 is articulated around a horizontal axis transverse 49 located just above the pivot 42.
  • the lever 46 is itself articulated on the lever 47 at its upper part around a transverse axis 50.
  • the slotted lower end of the lever 46 bears against the head 51 a rod 52 directed in the axis of the binding and provided with a bearing 53 on which the ends 54a and 55a of two bent levers 54 and 55 are mounted, respectively mounted on a vertical axis 56 and 57 on the movable part 7 of the plate ( Figure 6).
  • the rod 52 ends with a lock 58 intended to lock the heel in rotation on the plate. Consequently, the spring 45 pushes, via the lever 46, the head 51 in the direction of the arrow F1, the levers 54 and 55 therefore tend to rotate in the direction indicated by the arrows while bracing themselves on the fixed stops 38 and 39.
  • the reaction of the stops 38 and 39 therefore tends to push the part 7 of the plate towards the front, so that the part 27 of the plate 24 is in abutment against the edge 40.
  • the stop could be made in the center, by the rear end of the cutout 17 against the pivot 3.
  • FIG. 7 illustrates the forces appearing at the front of the binding which has just been described.
  • a vertical force on the front stop 5 results in a vertical force P1 on the plate 4.
  • This force P1 is divided into two forces P2 and P3 on the edges 20a and 20b of the sliding plate 20.
  • On the trigger guard 21 there is a force P4 equal to force P1.
  • FIG. 8a shows a plate 80 engaged by a bearing 81 under a fixed bearing 82 secured to a base 83 fixed to the ski.
  • a vertical force P1 on the plate 80 results in a moment M1 at the base of the bearing surface 81 and in a moment M3 at the base of the bearing surface 82, which itself results in a tensile force P2 on the screw fixing of the base 83.
  • FIG. 8b shows the position of the same elements after shortening of the underfoot plate.
  • the ranges 81 and 82 are no longer in support of each other except by their ends.
  • the moments M2 and M4 at the base of these ranges are respectively greater than the moments M1 and M3 and the traction P3 on the fixing screw of the base 83 is much greater than P2.
  • the plates 20 and 24 are less stressed and could be made of a material other than steel, for example synthetic material.
  • the binding according to the invention also has the advantage of not requiring a precise adjustment of the distance between the heel piece and the front stop, since a too short distance is automatically compensated for by the retraction of the movable part 7 of the plate and the compression of the spring 45, as is the case in the independent heel and abutment fasteners, without the plate. There is therefore an automatic adaptation of the binding to the length of the sole of the shoe.
  • the principle of the guide means described is also applicable to a plate carrying only the means for holding the shoe front or rear.
