Definitions

  • the present invention relates to an abutment before attaching a boot to a gliding board.
  • front stops incorporate a lateral release mechanism of the shoe associated with the rotation of two wings. Both wings are forced by a spring so that they enclose the front of the shoe. As soon as a lateral threshold force is exerted on the front of the shoe, a wing opens, thus releasing the shoe. This mechanism thus ensures the safety of the skier in case of a fall.
  • This mechanism is often adjustable so that the value of the lateral force threshold is adapted to the specificities of the skier.
  • the adjustment of the trigger value consists of modifying the spring stiffness for a determined trip stroke.
  • Some of these front stops incorporate, in addition, a mechanism for changing the position of the lateral release range with respect to the opening angle of the wings.
  • the angular trip interval can thus be shifted without modifying the trip path associated with a stiffness of the determined spring.
  • one solution is to change the position of the bearing surface against which presses the trigger spring acting on the wings.
  • This construction is illustrated in particular in the document EP 2 929 919 .
  • vertical pins are embedded in respective wings. Each of these pins is eccentric with respect to the pivot axis of its wing.
  • the abutment comprises a connecting piece slidably mounted relative to the frame in a longitudinal direction. The connecting piece is biased towards the rear by the second end of the spring.
  • the connecting piece comprises two vertical bores
  • the pins are engaged in the vertical bores, so that any longitudinal sliding of the connecting piece leads to an identical translation of the pins.
  • any sliding of the connecting piece leads to a simultaneous pivoting of the two wings.
  • This solidarity between the wings can disrupt the operation of the trigger mechanism. Indeed, this can generate a blockage in the kinematics of the wings or a modification of the trigger values, these malfunctions resulting, for example, by bracing or if one of the wings gets stuck.
  • this design brings sizing and assembly constraints.
  • the object of the invention is to provide an improved front stop.
  • One aim is notably to propose an alternative solution to the stops of the prior art.
  • Another goal is to provide a reliable lateral release mechanism.
  • Another goal is to allow the skier to maintain better control of the gliding board during a small pivoting of a wing.
  • Another goal is to have a simple abutment structure.
  • Each wing comprises an actuating member intended, during the opening of the wing, to cooperate with a face of the connecting element so as to cause the translation of the connecting element when the wing pivots in a meaning, this translation does not cause the rotation of the other wing.
  • the invention allows to rotate only the wing solicited by the shoe in the down position.
  • a wing rotates only slightly without opening
  • the shoe of the user is immediately recalled to contact with the other wing that has not been solicited.
  • the return force is transmitted more directly to a single wing.
  • the maintenance of the shoe is then immediately ensured, ensuring the transmission of desired forces between the shoe and the front stop, and thus optimal control of the gliding board by the user.
  • the invention also makes it possible not to open the two wings automatically if only one of them is stressed laterally by the shoe of the user.
  • the invention also makes it possible to obtain these functionalities without inducing excessive complexity of the front stop.
  • the reliability of the triggering mechanism is improved. Indeed, if the kinematics of a wing is defective, for example, the rotation of a wing is blocked, it does not disturb the kinematics of the other wing. It is thus possible to trigger the other wing.
  • the invention relates to a fastening of a shoe 8 on a gliding board 7, such as a ski, comprising a rear retaining device of the boot, called “heel” and more particularly a front retaining device of the boot,
  • the sliding board 7 comprises an upper surface 71 on which the elements of the binding are fixed.
  • the gliding board 7 comprises a lower surface 72, or sliding surface, intended to be in contact with the snow.
  • the combination of the shoe 8 with the front stop 1 and / or the heel ensures the fastening of the shoe with the gliding board.
  • the gliding apparatus 9 designates the gliding board 7 equipped with a binding.
  • the invention relates more specifically to a stop before 1 of such a fixation.
  • the shoes 8 adapted to the binding according to the invention generally comprise a shell provided with two removable tips attached under the shell, a rear end, located under the heel and a front end, located under the toes.
  • the sole of the shoe is thus formed by the two ends and the lower part of the shell.
  • the invention is not limited to this type of shoe and also relates to other constructions of the shoe, for example, shoes without removable tips, the sole can be integrally formed by the lower part of the shell.
  • the stop before 1 is designed primarily for the practice of ski touring although it could also apply to a practice of alpine skiing only. It comprises two front retaining devices of the boot that are alternately used depending on the phase of ski touring: ascent or descent.
  • a first front retainer 11 of the front stop is intended for the climbing phases. It cooperates with a front portion 81 of a shoe 8 so as to allow the rotation of the shoe around a hinge axis Y11, extending transversely to the gliding board, at the front of the shoe .
  • the boot 8 When the boot 8 is engaged with the first front retainer 11, it can freely rotate about this axis. For this, the heel of the shoe does not cooperate with a heel.
  • a second front retainer 12 of the front stop is intended for downhill or downhill skiing.
  • the shoe 8 When the shoe 8 is engaged with the second front retainer 12, it is immobilized between the heel piece and the second front retainer 12.
  • the shoe heel thus cooperates with a heel piece, not shown, contrary to the previous configuration.
  • the front stop 1 can be set in four configurations.
  • a first configuration, called downhill, illustrated in the figures 2 , 6 , 12 , 14 corresponds to the adjustment of the stop allowing the shoe 8 to cooperate with the second front retainer 12.
  • a second configuration, known as a boot, illustrated in the figures 4 and 7 corresponds to the setting of the stop allowing the release of the shoe 8 when it is engaged with the first front restraint 11.
  • the shoe does not cooperates neither with the first front retainer 11, nor with the second front retainer 12.
  • a third configuration, called climb, illustrated in the figures 1 , 5 , 9 , 13 corresponds to the setting of the stop for the cooperation of the shoe with the first front retainer 11. For this configuration the opening of the wings is blocked.
  • a fourth configuration, called rest, illustrated in the figures 8 and 10 corresponds substantially to the third configuration, the stop being adjusted so as to allow the shoe to cooperate with the first front retainer 11. This configuration differs from the previous one in the sense that the opening of the wings is not blocked.

  • This angle makes it possible to position the attachment means 219, 229 so as to cooperate with the front portion 81 of a shoe 8. If the wings are further opened, then the springs 64 tend to close the wings to find this angle d stable wing opening ⁇ M If the wings are further closed, then the spring 63 tends to open the wings to find this stable angle of wings ⁇ M. Consequently, this fourth configuration makes it possible to maintain the attachment means 219, 229 in engagement with the front portion 81 of a boot 8. This retention makes it possible to hold the boot with the gliding machine for displacements for which the wings are little solicited. This maintenance is however not sufficient during climbing phases during which the wings are more stressed laterally. This is why it is planned to lock the opening of the wings with a third configuration of the front stop.
