Definitions

  • the present invention relates to an abutment before attaching a boot to a gliding board adapted for the practice of ski touring.
  • the climbing phases require a fixation of the ski boot functionally very different from the downhill phases. This results in requirements in terms of safety and holding of the binding and kinematics of the shoe variable from one phase to another.
  • the binding must ensure a very good support of the boot on the ski with, preferably, triggering the binding in case of a fall so as not to hurt the skier.
  • it is necessary to allow a rotation of the boot around a transverse axis substantially at the front of the sole of the shoe. The shoe is therefore not immobilized with respect to the ski and there is no need to trigger the attachment uphill.
  • bindings have been designed specifically for the descent. Often, these include a front stop incorporating a lateral release mechanism associated with the pivoting of wings for gripping the front of the shoe. Such a stop is thus described in the document FR-A-2,089,540 .
  • the forward stop described in the document EP-A-0 199 098 refers to the practice of ski touring.
  • This solution comprises a shoe attachment mechanism defining a hinge axis around which pivots the front of the shoe during the climb.
  • This solution comprises a first forward restraint of the boot provided for the descent comprising two pivoting wings associated with a lateral release mechanism.
  • the wings support interface surfaces intended to come into contact with the front of a sole of the shoe in order to maintain the front of the shoe vertically and laterally.
  • This forward stop also includes a second front retainer of the boot provided for the climb. This second front retainer comprises two points, each being respectively fixed on an extension of a wing, above the interface surfaces.
  • the same piece consisting of a single material, which defines the contact surface serving as a vertical stop at the front of the shoe and which constitutes the connection between the pivot axis of the shoe.
  • wing and the associated tip of the attachment mechanism of the shoe Because the housing serves as a top stop at the front of the shoe, everything leads to consider a plastic housing to facilitate the sliding of the shoe relative to the wing, during a lateral release.
  • the wings described have a mass structure to stiffen the connection between the pivot axis of the wing and the associated tip of the attachment mechanism of the shoe. This connection must be rigid to ensure good stability of the shoe during climbing phases. Indeed, during these phases, the shoe can exert significant lateral forces on the wings that can open, by deformation, in the case where the connection described above is not rigid enough. Also, to obtain a good behavior with a plastic casing, it must be mass.
  • the object of the invention is to provide an improved front stop.
  • One purpose is in particular to limit the variation of position of the tips relative to the chassis during use in the climb phase.
  • Another purpose is to facilitate the lateral release of the front stop.
  • Another goal is to reduce the clutter of the wings and, in particular to lighten them.
  • Another purpose is to simplify the design of the structure of the front stop.
  • Another object is to limit the deformation of the elements of the transmission chain of forces between the trigger mechanism and the wings.
  • the stop is characterized in that the frame is metallic and the horizontal contact surface is defined by a plastic end piece.
  • This construction combining two materials for the construction of the wing allows, on the one hand, to obtain sufficient rigidity for a small footprint, with the metal frame, and, on the other hand, to obtain sufficient slip between the shoe and wing, when the lateral thrust of the front stop, with the plastic tip. Thanks to the plastic tip, the coefficient of friction at the contact with the top of the front portion of the boot is reduced, which makes it possible not to degrade the triggering characteristics of the front stop. Thanks to the metal frame, the attachment means remain in contact with the shoe when it is engaged with the stop configured for climbing. In fact, this rigidity makes it possible to limit the variation of position of the hooking means with respect to the chassis during use of the stop during the climbing phase.

  • the combination of the shoe with the front stop 1 and / or the heel ensures the fastening of the shoe with the gliding board 9.
  • a gliding device refers to the gliding board 9 equipped with a binding.
  • the invention relates more specifically to a stop before 1 of such a fixation.
  • a mark will also be used whose longitudinal or front / rear direction corresponds to the X axis, the transverse or right / left direction corresponds to the Y axis and the vertical direction or up / down direction corresponds to the Z axis.
  • the shoes adapted to the binding according to the invention generally comprise a shell provided with two removable tips fixed under the shell, a rear end, located under the heel and a front end, located under the toes.
