Definitions

  • Arrangements for securing skis are already known which include various shapes of plates acting as toeclamps and adapted to pivot with reference to-a pin positioned either to the front or to the rear of said plates.
  • the toeclamps are secured no longer directly to the ski but to two intermediate plates pivotally mounted on two pivots rigid with the ski and .locked each in position by at least one-thrust-exerting finger cooperating with a cam pivotally securedto a. further pivot and possibly rigid with the said intermediate plate, the said finger holding elastically in their closed position the toe-clamps through the agency of the said pivoting cam.
  • the securing arrangement produces the same effect as any other good securing arrangement which is not provided with a safety device, and this is true in all circumstances and in particular in the so-called edgewise movement during which the skier instead of setting his skis fiat on the ground causes the edges of the ski to engage the ground so as to form a brake or else to change the direction of progress.
  • the two plates carrying the toe-clamping jaws pivot round spindles located to the rear of the latter and a single finger positioned to the front of the said toeclamps holds both plates in position through a cam which is inserted between the finger and the plate and which is provided on one hand with at least one notch engaged by the finger urging it into the position corresponding to the closing of the toe-clamp and on the other hand with a recess adapted to be engaged by two tenons forming the front ends of the two plates.
  • the toe-clamps may be secured in any suitable manner allowing them to be adjusted with reference to the plates and they may also be secured indifierently above and underneath their carrier plates.
  • Fig. l is a side elevational view of the first embodiment referred to.
  • Figs. 2 and 3 are plan views from above of the same "ice 2 embodiment respectively in its'toe-clamp-closing and in its toe-clamp-opening position.
  • Fig. 4 is a plan view from above showing the position of the toe-clamps, immediately before their return into their closed position.
  • Fig. 5 is a sectional view through line 5-5 of Fig. 2.
  • Fig. 6 is a plan view on an enlarged scale of the cam as seen from above.
  • Fig. 7 is a detail view showing the finger exertinga thrust on the said cam.
  • the securing arrangement illustrated includes toeclamps comprising two jaws 2 of conventional'type, secured no longer directly to a plate rigid with the ski but to two intermediate plates 3 each pivotally secured to the ski 4 through a pin or spindle 5 screwed into the ski to the rear of the corresponding jaw 2. 7
  • These plates 3 are provided with serrated projections 6 which allow securing adjustably the jaws 2 to the said intermediate plates through engagement with serrated sections of'the jaws; said jaws are then held fast on the plates by means of screws 7' extending through elongated ports 8 formed in the jaws 2.
  • the front ends of the intermediate plates 3 carrying the jaws 2 are provided each with a tenon 9.
  • the two' tenons 9 lie in juxtaposed location inside the recess 10 of a member 12 acting as a cam and adapted to rock round a screw 11 forming a pivot for the said cam-shaped member 12.
  • the said cam-shaped member '12 is provided in its front surface with a medial notch 13 to either side of which are formed two further identical notches 14' and 15.
  • the size and outline of the notches 13, 14 and 15 are such that they allow the engagement therein of a ball, finger or the like projecting member 16 housed inside'a cylindrical chamber 17 extending longitudinally of the ski, said ball being submitted to the action of a spring '18"urging it outwardly of said chamber17 and into en gagement with the cam 12.
  • the front end of said spring 18 bears against a plug 19 screwed inside the front end of the chamber 17.
  • the toe-clamp opens under the action of an excessive stress exerted laterally by the foot of the skier on the right hand jaw 2 in the direction of the arrow 21 of Fig. 2.
  • the tenon 9 of the said jaw produces a rocking of the cam 12 round its pivot 11 so that the said cam enters the position illustrated in Fig. 3 for which position the tenons 9 on the plates 3 are released with reference to the recess 10 of the cam while said cam is held fast through engagement of the ball 16 inside the notch 15.
  • a plate 20 secured coaxially to the cam 12 by the screw or pivot 11 covers the said cam and the tenons 9 of the plate 3 so as to prevent any tearing out of the plates when the toe-clamps are closed.
  • the operation of the safety system is entirely independent of the tensioning of the cords or the like yielding membersholding the foot and this allows retaining the safety means both when the actual foot-holding system is loose, with a view e. g. to allowing progression over flat ground or on an upwardly directed slope and when the foot-holding system is tensioned so as to hold the foot fast on the ski, i. e. during downward movement;
  • a shoe-securingarrangement comprising two pivots rigid with the ski, arranged symmetrically to either side of the longitudinal axis of the ski, two similar plates pivotally secured to said pivots and adapted to slide over the upper surface of the ski into forwardly directed interengaging operative positions, cooperating jaws rigid with the outer front sections of the two plates and adapted to enclose a shoe toe between them, tenons projecting to the front of each plate and engaging each other when said plates are in their forward interengaging positions, a cam pivotally secured to the ski at a point of the longitudinal axis of the ski to the front of the operative positions of said tenons, and the rear surface of which is provided with a recessed section adapted to face each tenonin its operative position and to hold the interengaging tenons fast inside it, said cam being provided along its front periphery with three notches of which the central notch is diametrically aligned with the contacting line between the tenons and the
