Definitions

  • the present invention precisely has for its object to remedy this drawback and accordingly seeks to provide a rear ski or anchor binding comprising a jaw intended to be folded over on the edge of the heel of the ski boot to ensure its blocking 4against a stop integral With the ski, means for locking the jaw in folded position, a pedal adapted to be moved from a higher to a lower position by the heel of the skiers boot when the same puts on his ski and with a kinematic linkage between the jaw and the pedal arranged in such a way as to occasion said folding over of the jaw when the pedal is placed into its low position by the skier, this new binding being further characterised by the fact that this linkage makes possible the relative movement of the pedal and of the jaw at the end of the path of travel of these elements.
  • the step of placing the jaw under tension takes place during a greater or smaller movement of the jaw in proportion of the degree of flexibility of the elastic locking means of the binding.
  • the pedal serves to cause the approach of the jaw by bringing it in a position such that its placing under tension can begin and thereafter has no functional role: if this pedal is connected to the jaw in its movements, it must be able to move therewith also during the elementary movement required by the placing under tension. It will be understood then that as soon as a deposit of snow forms which will prevent this terminal movement of the pedal this ⁇ will also prevent the placing under tension of the jaw.
  • the bindings now known have a housing permitting the retraction of the pedal and which is located under the support level of the heel of the boot at a distance from this level at least equal to the distance which the jaw must still travel in order to be placed under tension starting from the moment when it has been brought sufficiently near the heel of the boot to lock.
  • the arrangement provided in the present invention makes possible the elimination of this housing so that at the beginning of the step of approach of the jaw, the opening pedal-jaw can be as great as desired which permits to avoid all encounter between the jaw and the upper part of the ski boot during the performance of this first step.
  • FIGURES l to 3 are each longitudinal cross-sectional views of the same embodiment in three different operating positions.
  • FIGURES 4 to 6 show more schematically three different views of another binding according to the invention.
  • FIGURES 7 to 9 show schematically a third embodiment of the invention in its three functioning positions.
  • FIGURES l0 to 16 show schematically in elevation seven other modifications of the embodiments shown in FIGURES 7 to 9.
  • FIGURES 17 and 18 are schematic elevational views of a fourth embodiment of the device' of the invention.
  • the binding according to the invention comprises a base plate 1 secured to the ski 2 by means of screws 3, the left hand extremity of which has a rib 4 forming a stop on which will bear the heel of the skiers boot and on which is mounted by means of slides 1a, a sole 6 longitudinally slotted at 7 and the axial position of which on plate 1 can be adjusted by tightening a screw 8a on a bolt 8b passing through slot 7 and integral with said plate 1.
  • a casing 9 connected to the sole by a compression spring 10 between a projection 6a thereof and an element 11 of casing 9 forming a cam for a stop 12 for locking the binding and mounted on the left hand extremity of a rod 13.
  • This rod is engaged by its threaded part 13a in a passage provided in the common part 14a of a spur 14 the parallel branches of which are pivoted on a shaft 15 transversal to the ski and Which is carried by a lever 16a pivoted at 17 on the casing, the shaft 15 being excentric by a suitable distance relative to shaft 17.
  • Rod 13 is elastically connected to spur 14 by means of a spring 17 under compression between part 14a of the spur and a tightening head 18 constituted by a screw in mesh with the thread 13a of the rod and the axial position of which can be adjusted in function of the compression to be given to spring 17
  • stop 12 can have two positions: one upright in which it is maintained by contact with the upper face of cam 11, and the other lowered, in which it is in contact with the inclined left surface of this cam under the urging of the rounded lower edge of beak 19 and against spring 17 which is under compression.
  • stop 12 takes care of the angular locking of the beak which is secured at the extremity of a lever 20 pivoted around a shaft 21 and which bears on its left hand face two legs 22 between which is pivoted a threaded rod 23 the upper extremity of which is slotted by the transversal slot 23a. intended for engagement by a tool, screw-driver or simply the edge of a coin.
  • a member 24 constituting the jaw by which the binding according to the invention is able to take hold of the heel of ski boot 5.
  • Plate 25 is thus free to move angularly without moving lever 20 and jaw 24 rigid therewith as long as it does not come into contact with the extreme lower or higher part of the edges defining slot 26a.
  • the anchor shown opens automatically as soon as a given effort greater than that necessary for compressing spring 17 acts in clockwise direction on jaw 24.
  • the intensity of this effort which can for example be occasioned by the fall of the skier, is adjustable by a greater or lesser screwing in of nut 18.
  • beak 19 acts on stop 12 driving it to the left by compression of spring 17, the opening of the anchor taking place when this stop is brought to slide on the inclined edge of cam 11.
  • this anchor binding can also be opened by direct action of the skier on lever 16 in tipping the latter in a position shown in FIGURE 3, which has for result to lower stop 12 and to thus free beak 19.
  • the pedal is lformed by the left hand side extremity 27 of a lever 28 pivoted on a shaft 29 integral with a casing which is not shown.
  • This casing can, as before, be mounted flexibly and slidably on the ski.
  • Lever 28 carries a shaft 30 mounted near pedal 27 and engaged in a slot 31 cut in the lower part of an inverted L-shaped piece 32 the shortest branch of which, 33, forms the securing jaw of the binding.
  • This jaw is represented as being fixed, but it is evident that it can also be constituted by a distinct piece mounted on threaded rods integral with piece 32 which would permit to adjust its vertical position in the manner described on FIGURES 1 to 3.
  • This pie/:e 32 is additionally connected to a shaft 34, secured to the casing (not shown) of the anchor, parallel to shaft 29, by means of a small rod 35 to which it is pivoted at 36.
  • piece 32 At its lower part, opposite to pedal 27, piece 32 additionally carries a beak 32a, the extremity of which can for example be provided with a roller by means of which it is in permanent contact with the edge of cam 37 which is pivoted around shaft 34, previously mentioned, and also subjected to the action of spring 38 tending to urge it against beak 32a of piece 32.
  • This cam 37 has an L- shaped prole.
  • lever 28 In the released position of the heel anchor, lever 28 is slightly upwardly inclined and beak 32a bears against the left hand side of cam 37, the spring 38 being then compressed to the maximum.
  • the extent of compression of this spring naturally can be adjusted by any suita-ble means which need not be shown.
  • the opening of the heel ancher described can also be obtained by exerting on jaw 33 an effort tending to move away from the surface of the ski against spring 38.
  • FIGURES 5 and 6 show the functioning of the heel anchor when the surface of the ski is covered by a layer of snow having thickness e.
  • the heel anchor according to the third embodiment is essentially formed by two levers 40 and 41 pivoted around a common shaft 42 and by an elastic locking system cornprising a ball 43 slidably mounted in a cylindrical passage 44 provided in case 45 of the heel anchor, shown schematically in the drawing, this ball being subject to the urging of an adjustable spring 46.
  • Ball 43 is constantly applied by this spring against the edge of a cam 47 formed in the right arm of lever 41, the left arm of which 41a, constitutes the jaw of the anchor.
  • This jaw can also be independent of lever 41 and be secured thereto by any suitable means permitting to modify the relative position thereof.
  • the section of the cam terminates near its lower section by a type of nick in which enters ball 43 in bound position of the anchor.
  • Jaw 41a which is driven into this position by the action of the skiers heel on the lever 40, the left arm of which 40a forms an actuating pedal and the right arm of which, 40b, substantially shorter than the left arm, constitutes the element by means of which lever 40 acts on lever 41 to cause the tipping in direction F.
  • FIGURES 8 and 9 show the behaviour of the anchor when the ski is covered by a layer of hard snow of thickness e.
  • the anchor is actually so proportioned that when pedal 40a enters into contact with this layer (FIGURE 8), the tipping movement of lever 41 is not completely terminated.
  • levers 40 ⁇ and 41 can be slightly different from that shown in FIGURES 7 to 9 in Order to permit the adjustment of the maximum spacing of these levers in order to adapt the anchor to boots having heels of different thicknesses (FIGURES 10 to 12).
  • the locking device 43 to 46 or any other similar device, will also be provided even though it is not shown: it will be arranged in such a way as to exert its action on a suitable part of the lever forming the jaw.
  • pivoting axes of the two levers can coincide (FIG- URE 10) or, on the contrary, can be distinct (FIG- URES 11 and 12).
  • one of them can be connected to the other by means of a flexible member such as a spring as in FIG- URE 12.
  • the anchor can comprise two levers 47 and 48 pivoted around the same shaft 49, the left arm of lever 47 constituting the gripping jaw and its right hand extremity being solicited by a locking mechanism, for example of the type formed by elements 43 to 46 of FIGURE 7.
  • Lever 48 assumes here the shape of a C, the lower horizontal branch of which forms the actuating pedal, the upper one carrying a rod 50 slidable axially against the urging of a spring 51, and the assembly constituted by this rod and this spring forming a pusher by means of which lever 48 is able to drive lever 47 when it is urged in the direction F by the heel of a boot acting on the pedal.
  • the heel anchor according to the invention comprises a lever 52 pivoted at 53 and forming a jaw at its left hand part and a pedal 54 constituted by the horizontal branch of a L-shaped binding iron slidably mounted in a passage 55 of lever 52.
  • the relative axial position of this binding iron is determined on the one hand by support head 56 and on the other hand by a spring 57 under tension between lever 52 and pedal 54.
  • the locking of lever 52 is possible by pushing on its right hand extremity.
  • the heel anchor is formed by a L-shaped lever, 58, pivoted at 59 and the horizontal branch of which 58a forms the gripping jaw of the anchor, the lower extremity of the vertical branch of lever 58 forming a beak 58b on which bears an elastic blade 60, in the shape of a C.
  • This blade is engaged by its vertical part through a passage 61 provided in lever 58 and bears by its upper horizontal branch on the upper edge of jaw 58a: it is the lower horizontal branch of blade 60 which forms the actuating pedal of the anchor, this pedal thus being able to bend when it encounters an obstacle such as a layer of snow, without causing the stopping of jaw 58a.
  • FIGURE 16 is an extrapolation of that shown in FIGURE 15.
  • the anchor comprises a jaw constiuted by the horizontal branch of a L-shaped lever, 62, pivoted around a shaft 63, but the pedal has been secured to the lower extremity of the vertical branch.
  • This pedal is formed by the left arm of lever 64 pivoted at 65 on lever 62 and bearing on the dorsal part there of by its right arm.
  • lever 62 in gripping position can be effected by any suitable means as is the case for the other previously mentioned modifications.
  • the heel anchor according to the invention is formed by two levers facing one another 66 and 67, pivoted at 68 and the left part of which forms respectively the jaw and the pedal.
  • the right extremities of these levers are in contact with the opposed edges of a tipping lever 69 pivoted at 70 which they grip and which constitutes the kinematic linking element for levers 66 and 67.
  • Tipping lever 69 is naturally subject to the action of elastically operating locking members capable of bringing lever 66 in tightening position (illustrated in dotted lines in FIGURE 17) at the instant when pedal 67 has been stopped in its path by an obstacle (position corresponding to the fastening elements illustrated in full lines in FIG- URE 17).
  • the anchor could be provided with locking members acting on lever 66 and on tipping lever 69.
  • tipping lever 69 can have a shape designed in order to permit the control of the law of variation of the opening pedal-jaw along the movement of these two elements.
  • the invention is naturally not limited to what has been represented or described: in particular the inventive principles constituting the basis thereof can be carried out with an anchor the movement of whose jaw or of whose pedal would be different from those mentioned.
  • the locking and moving device for the anchor can be any whatever.
