Definitions

  • the present invention relates to a device, preventing a ski from sliding backwards, comprising a support intended to be fixed on the ski and on which at least one retaining member is articulated, this member being capable of pivoting from an inactive position towards an active position in which it cooperates with the snow to prevent the ski from moving backwards.
  • a device is already known (CH-A-501.413 and GB-A-471.586).
  • This device comprises a support on which a part in the shape of a "U" is articulated.
  • the two arms of the "U" which carry claws; are constantly solicited towards an active position, substantially vertical with respect to the plane of the ski, in contact with abutments, by a spring against the action of which, when the ski is advanced, the "U" part acts in order to be brought back.
  • this device has the disadvantage of always braking the ski because the two arms are constantly engaged in the snow uncontrollably including downhill.
  • the object of the present invention is to remedy these drawbacks.
  • control means some ensuring the actuation of the claws, the others controlling the extent of this actuation, in particular characterized in that at least one of these control means is connected to the pivot shaft of the claws by means of means for adjusting its action on the claws.
  • the support 1 is capable of being mounted on the ski directly or preferably by means of a basal plate 11 ensuring its rapid removable and having for example a front part 6 and a curved rear edge 7, as well as holes 8 allowing it to be screwed onto ski.
  • the spacer 4 of the support which comprises for example protruding portions 4a, is intended to be engaged in the curved rear edge 7 of the base plate 11, while the front plate 3-of the support is applied to the front part 6 of the basal plate 11 on which it is removably fixed thanks for example to a wing nut 9 and a screw 10.
  • the support carries a pivot shaft 12 which, for example, crosses the two side walls 2. It carries at at least one of its ends an anchoring claw 13, 14.
  • claws 13, 14 and the pivot shaft produce a part in the shape of a "U” or "L” constituting the retaining member cooperating with the snow.
  • these claws have a cross section in "L" 'and therefore each have two wings 15 and 16 or 17 and 18 perpendicular to each other, one 15, 17 called braking, being located in a plane comprising the axis of the pivoting shaft 12 or substantially parallel thereto, the other 16, 18 known as vertical, being situated in a plane with respect to which the axis of this shaft 12 is perpendicular, this vertical wing being intended to give the ski good lateral stability.
  • the claws 14 intended to be mounted on the interior side of the skis may have a braking surface 17 that is narrower than that of the outer claws 13.
  • the two claws 13, 14 may have at their ends, a toothing 19 facilitating penetration in the snow and allowing the attachment to the ice.
  • claws of different lengths and, for example, longer for deep powder snow than for use on an icy surface.
  • the shaft 12 can pass through the vertical wing 16, 18 of each claw 13, 14 in the form of a longitudinal light 52 and it suffices then loosen the nuts 20 to be able to bring said claws 13, 14 to the desired length.
  • the device further comprises control means 21, 24, some 21 ensuring the actuation of the claws 13, 14, the others 24 controlling the extent of this actuation.
  • At least one of these control means 21, 24 is connected to the pivot shaft 12 by means 23 for adjusting its action on the claws.
  • the actuating means 21 preferably consists of a counterweight 30 connected to the pivot shaft 12 to form with the claws 13, 14 a balance 25 sensitive to the inclination of the longitudinal axis of the ski 22.
  • the adjustment means 23 capable of being interposed between the counterweight 30 and the claws comprises, for example, a rod 26 associated with the shaft 12, and on which, by one of its ends, is articulated around a axis 28 a second rod 27, the other end of which carries the counterweight 30.
  • the axis 28 will for example consist of the rod of a screw 28 and nut 29 assembly.
  • this articulation 28 which makes it possible to adjust the action of the counterweight 30 to control the tilting during a more or less significant inclination of the ski.
  • the adjustment means 23 capable of being interposed between the counterweight 30 and 1es_ claws comprises only a rod 26 carrying directly at one of its ends 38 the counterweight 30 but, then at least in this case, the claw or the other end of the rod is associated with the shaft 12 by means of a ring 39 provided with means 40 to 43 both immobilized with respect to the shaft 12 and with adjustment in orientation around the axis of this tree 12.
  • these means consist of complementary grooves 42 executed in the bore 40 of the ring and on a bearing surface 41 of the shaft 12.
  • the bore of the ring 39 and the bearing 41 of the shaft 12 are cylindrical but if the ring comprises a member 43 for locking on the shaft such as a pressure screw 43 passing radially through the ring 39.
  • the ring is interposed between the rod 26 and the shaft 12 and the pressure screw 43 is advantageously constituted by the threaded end 37 of the rod 26 carrying the counterweight.
  • stops determine the so-called extreme positions of the claws, extreme positions in which they are oriented either substantially parallel to the skis 22 (FIG. 4b) and therefore inactive, or substantially perpendicular to the skis and then offer optimal cooperation with the snow (Figure 4a).
  • the extreme stops can cooperate directly with the claws.
  • these stops are formed by the ends of at least one spacer 32, 33 carried by the support from which it passes through the side walls.
  • the means 24 controlling the amplitude of the actuation of the claws and which, for this purpose, define the narrower limits of movement within these maxima, which are chosen for example, either to prohibit the return to the fully inactive position, either to limit the output of the claws to their active position, or both at the same time, may consist of at least one stop carried by the support so as to cooperate directly with the claws.
  • the extreme stops and / or the means 24 controlling the amplitude of the actuation of the claws cooperate with at least one stop 26 associated with the pivot shaft 12.
  • the stop 26 is associated with the shaft 12 by a ring 39 which is both immobilized relative to the shaft and adjustable in orientation around this shaft 12.
  • this ring 39 is constituted by that carrying the counterweight and / or the stop 26 is constituted by the rod 26 associated with this ring for carrying the counterweight 30 and therefore benefits from the same adjustment means 23 as this control means.
  • the stop 26 which is movable, then cooperates with at least one fixed stop 47, 48 carried by the support.
  • the fixed stops 47, 48 are constituted by rods or pins located in one of the orifices 46 made for this purpose in at least one wall 45 such as at least one of the side walls of the support or a semi-circular sector substantially centered on the axis of rotation of the shaft 12 and oriented in a plane parallel to the plane of movement of the movable stop 26.
  • the fixed stops 47, 48 are formed by the ends of a light executed in a part 35 secured to the support and oriented in a plane parallel to the plane of movement of the movable stop which is engaged therein.
  • the actuating means 41 consists of an elastic element, this is preferably associated with a ring 39 of the aforementioned type, and this, of course at a point situated outside the axis of the pivot shaft 12.
  • the device is provided with a front cover 35, for example made of plastic, engaging in friction on the front part of the support 1.
  • This cover 35 prevents snow from entering the interior of the support so that the tilting part is not hampered in its movement.
  • the device is preferably mounted immediately before the binding of the boots 36 on the ski 22 as illustrated in FIG. 4.
