Definitions

  • the present invention has for an object a ski attachment comprising a stretcher for a traction cable surrounding the boot and passing behind the heel, this stretcher having a tension lever on which is hinged a cable holding device.
  • the attachment according to the invention is characterized in that it further includes a safety element mounted to slide along the axis of the ski, against the action of an elastic member, in a guide pivoting about a fixed axis relative to the ski and perpendicular to the axis of the ski.
  • This safety element is held at one end by a hooking member, and its other end is connected to the tension lever by a pivoting axis, the whole being arranged in such a way that the said lever may be normally manoeuvered about the' said pivoting axis independently of the safety element which it covers in the closed position and which only-frees itself from the hooking emember when the cable is subjected to a traction exceeding a predetermined amount, the line of force of the traction pulling the holding device of the cable passing between the axis of the pivoting part and the hinged axis of the tension lever.

  • FIGS. 10 and 11 are side elevational views, of two modifications of details.
  • FIG. 12 is an end view from the left of FIG. 11.
  • the ski attachment shown in FIG. 1 includes a stretcher for a traction cable (not shown) surrounding the boot and passing behind the heel, this stretcher being mounted on a plate 1 secured to the ski 2 and having .
  • a safety element including a rod 5 is slidably mounted along the axis of the ski, against the action of an elastic member 6 mounted on the rod 5, in a part 7 pivoting about an axis 8 fixed relative to the ski and perpendicular to the axis of the ski.
  • One end of the rod 5 is held by a hook 9 and its other end is connected to the tension lever 3 by a pivoting axis 10.
  • the rod 5 is provided with a threaded part carrying a nut 11 against which bears the elastic member 6 which bears on the other end against the pivoting part 7.
  • This nut 11 allows regulating the initial tension of the elastic member 6.
  • This elastic member is formed by a piling up of rings 12 of toroidal shape separated by rigid washers 13.
  • the hook 9 is pivotally mounted on a fixed axis 14 supported by two brackets 15 integral with the plate 1 and the base of this hook 9 has a flat part 16 adapted to "ice prevent the hook from falling when it is unhooked, one of the ends of this flat part abutting against the plate 1.
  • the cable holding device hinged at 4 on the lever 3, includes a fork 17 having a threaded rod 18 on which is screwed a traction hook 19 for hooking the traction cable (not shown).
  • a traction hook 19 for hooking the traction cable (not shown).
  • the tension lever 3 is normally manoeuvered about the pivoting axis 10 from the closed position of FIG. 1 to the open position of FIG. 2, independently of the safety element which it covers in the closed position.
  • the rod 5 is drawn backwards against the action of the elastic member 6 through the agency of the lever 3, the line of force of the traction pulling the cable holding device passing between the axes 8 and 10, as shown in FIG. 4.
  • the traction exerted. on the lever 3 causes the part 7 to swing about its axis 8, and opens out the lever to the position shown in FIG. 5, the line of force of the cable holding device passing suddenly above the axis 10 from the position of FIG.
  • the stretcher is mounted on a plate 20 sliding on a plate 21 fixed to the ski 2 and having flanges 22 forming slides for the plate 20.
  • the front ends (that is to say directed towards the front of the ski) of the plates 20 and 21 are each provided with a bracket 23 and 24 respectively, constructed in one piece, formed by folding at right angles the end of the plate.
  • a screw 25 fixed to the bracket 23 passes through the bracket 24 and carries a knurl headed nut 26' allowing of adjusting by hand the longitudinal position of the stretcher relative-to the ski, that is to say the tension of the traction cable.
  • the cable hook 27 is hinged directly to the tension lever 3.
  • the operation of this attachment is the same as that of the embodiment of FIGS. 1 to 5.
  • the stretcher is mounted on a plate 28 sliding on a base plate 29 fixed to the ski 2 and which has flanges 30* serving as slides for the lateral edges of the plate 28 as shown in section in FIG. 8.
  • a spiral threaded knurled screw 31 gearing with a rack 32 of the plate 29, allows of moving the plate 28 with the stretcher in order to adjust the longitudinal position of the stretcher relative to the ski, that is to say the tension of the cable.
  • the knurled screw 31 is mounted in a fork 33 manufactured in one piece with the plate 28.
  • the front end of the rod 5 of the safety element is held by a hook 34 cut out in a metallic plate and pivoting on a fixed spindle 35 supported by two brackets 36 and 37 manufactured in one piece with the plate 28.
  • the base of the hook 34 is provided with a part 38 parallel to the plate 28 designed to prevent the said hook from swinging in a clockwise direction beyond the position shown in FIG. 8, and a part 39 inclined relative to the part 38 to allow the hook 34 to pivot in an anticlockwise direction.
  • a spring 40 one end of which is fixed to the plate 28 and the other to the hook 34 urges the latter in a clockwise direction when looking at FIG. 8.
  • the bracket 37 extends to the upper part of the hook and is provided with a V-shaped notch 41 adapted to guide the end of the rod 5.
  • FIG. 10 shows a variant of the mounting of the hook 9 of the embodiment of FIGS. 1 to 5.
  • the hook 9 may be adjusted longitudinally relative to the ski in order to change the freeing position of the end of the rod 5.
  • the pivoting axis of the hook 9' is constituted by a screw 42 on which is screwed a part of this hook forming a nut. 8
  • FIGS. 11 and 12 show a variant of a hook 34' of the same shape as the hook 34 but thicker, this hook 34 being pivotally mounted at 43 on an angle 44 fixed to the base plate 28, This angle could also be directly fixed to the ski.
  • the elastic member is constituted by rings of elastic material, of toroidal shape, it is obvious that one could also employ other elastic members capable of giving satisfaction, in particular coil springs or a piling up of elastic or conical washers, for example, so-callcd Belleville Washers.
  • a safety stretcher for ski fastening with a traction cable going behind the heel comprising a tightening lever, a cable-holding device pivotally connected to said lever, a guide pivoted on a horizontal axis fixed with respect to said ski and perpendicular to the axis of said ski, a safety component comprising a rod slidable in said guide axially of said ski, an elastic member cooperating with said rod to maintain the same in a set position, a hooking member pivoting on an axis extending longitudinally of the ski cooperating with one end of said safety component from which said component is freed only when the traction exerted on said cable against said elastic member exceeds a predetermined value for opening said tightening lever, said hooking member releasably holding said one end of said rod and said tightening lever being pivotally connected to the other end of said rod so that when said rod is drawn backwardly against the action of said elastic member through the agency of said tightening lever, the line of force of the traction pulling the cable holding
  • A. stretcher according to claim 1 wherein said guide has a longitudinal hole through which said rod passes and a transverse hole below said longitudinal hole through which said fixed axis passes.
  • a stretcher according to claim 6 wherein said support plate is integral with a projection guiding said rod, said projection being adjacent to said hooking member and having a V-shaped notch in which said rod is guided when being hooked, and a spring holding the hooking member elastically in hooking position.
  • said hooking member comprises a hook in a metal plate pivoted on a corner plate attached to the ski, the end of said cornerplate adjacent to said hook having a V-shaped notch to guide said rod. onto said book when it is to be booked, and a spring holding said hook elastically in booking position.
