Definitions

  • the invention relates to the field of sliding sports on snow and in particular alpine skiing.
  • the invention relates more particularly to a rear element of a ski safety binding, generally referred to as a “heel piece”, and more specifically to a so-called “pivot” type binding; that is to say a binding comprising a pivoting plate located at the heel of a ski boot intended to be securely retained by this type of binding.
  • a pivot attachment has, in addition to a pivoting plate, two ears emerging from the pivoting plate and each accommodate a lower end of two arms.
  • a suspended body is formed of an upper part in the form of a sleeve containing a thrust spring and of a lower part forming a heel grip intended to secure the ski boot to the binding. The latter is supported by an upper end of each of the two arms.
  • An example of a pivot attachment is described in the document FR-1,363,895 .
  • the heel grip of the suspended body is movable between two positions. A high position in which the heel of the shoe is free to move and a low position in which the heel of the shoe is blocked in translation by the heel grip of said suspended body.
  • Such a device makes it possible not to hinder the rotation of the heel of the boot while ensuring the automatic release of the boot in the event of a fall forwards.
  • the arms of a pivot attachment are generally telescopic rods formed by two parts screwed onto each other in order to allow adjustment of the length of the arms.
  • This type of mechanical part has the drawback of being easily deformed and / or out of adjustment during shocks or falls by the skier.
  • changing the arms is a complex procedure which often requires changing the entire rear binding. Which generates higher expenses.
  • the Applicant has produced a pivot attachment in which the side ears are connected to form a bar.
  • This bar is movable in translation to make it possible to adjust the longitudinal position of the suspended body, that is to say the length of the pivot fixing without modifying the length of the arms.
  • the arms can be made in one piece in a material that is more rigid and resistant to impact and deformation.
  • the translational adjustable part may include locking means on the bar.
  • the locking means are operable to allow the movement of said adjustable part in translation relative to the bar.
  • complementary interlocking elements can be provided to make it possible to make the part which can be adjusted in translation and the bar integral so that the movement of the part which can be adjusted in translation also makes it possible to modify the longitudinal position of the bar.
  • the bar is positioned below the pivoting plate to allow better resistance to tearing.
  • the width of the bar can also be chosen so that the ears of the bar come into contact with the lateral edges of the pivoting plate. In this way, the bar is held by the swivel plate.
  • the pivot binding may also include a base intended to come into contact with the upper face of the ski, and accommodating the pivoting plate.
  • the base can also include a reinforcing plate on its upper face so that the binding has better resistance to forces.
  • the pivoting plate comprises an oblong hole allowing the rotation of the pivoting plate about an axis perpendicular to the ski.
  • the pivoting plate is covered by a support plate intended to receive a ski boot.
  • This support plate protects the swivel plate from shocks and external aggressions.
  • the backing plate protects the translational adjustable part and the screws inserted through the rotating plate.
  • a first embodiment allows continuous adjustment of the longitudinal position of the suspended body through the use of a threaded rod mechanism and a second embodiment allows discreet adjustment through a notched mechanism.
  • the displacement of the nut along the threaded rod allows a continuous adjustment of the length of the fastener. Continuous adjustment provides greater precision in the adjustment.
  • connection between the nut and the bar can be made according to several scenarios.
  • the nut is provided on its edge with a fitting element cooperating with the bar so as to drive the bar in a movement of displacement along the longitudinal axis of the binding.
  • the nut and the bar form a single piece so that it is possible to act on any part of the part to move it along the longitudinal axis of the binding.
  • the threaded rod has a head equipped with a recess designed to cooperate with a tool.
  • the head of the threaded rod is then accessible at the rear of the swivel plate to facilitate the longitudinal adjustment of the binding.
  • the part which can be adjusted in translation moves from notch to notch. This discreet adjustment allows the position of the suspended body to be changed.
  • the bar comprises two protuberances passing through the recess and coming into contact with the front and rear faces of the part adjustable in translation. These protuberances make it possible to make the part movable in translation integral with the bar.
  • the invention also relates to a ski equipped with a binding as described above.

  • the swivel plate 1 and the backing plate 8 also include two holes 18 of the same diameter so that it is possible to align the holes 18 of the swivel plate 1 with those of the backing plate 8 and with the threads. 27 of the reinforcement plate 11 to allow access, from the top of the fixing 100, to the head of the screws intended to fix the reinforcement plate 11 to the base 7.
  • a torsion of the boot causes a rotational movement of the assembly formed by the pivoting plate 1, the support plate 8 and the cover 17 around the axis A1.
  • a recentering part 15 associated with a system of thrust springs 14 makes it possible to exert both a recentering force on the pivoting plate 1 towards the longitudinal axis A2 of the binding 100 for slight twists of the boot and a pushing force on the rear of the boot to allow the correct operation of the front stop of the binding.
  • a bar 4 having two ears 3 at its ends is located between the pivoting plate 1 and the base 7 receiving the reinforcing plate 11.
  • the ears 3 are positioned in contact with the lateral edges of the pivoting plate 1. However, the ears can emerge from the swivel plate via longitudinal grooves made in the swivel plate.
  • the bar 4 has a rectangular base or long edges of rounded shape without changing the invention.
  • the ears 3 emerge perpendicularly with respect to the base of the bar 4, preferably at the level of the ends of the base. However, provision can be made for the ears to emerge in any other region of the upper surface of the base of the bar 4.
  • the ears 3 may have a semi-circular shape or a rectangular shape without changing the invention.
  • the bar is made of a very rigid material, of the metal or even composite type, which also allows it to have a small thickness, for good mechanical strength.
  • the bar has a thickness of the order of a millimeter in its transverse portion, which has a very low impact on the overall thickness of the heel piece.
  • the ears 3 are crossed by a rivet 9 making it possible to secure the ears 3 and the lower ends of the two arms 5.
  • the rivets 9 are replaceable by any other device making it possible to connect the ears 3 to the arms 5 while allowing the arms 5 to be movable in rotation around the axis of the ears 3.
  • the arms 5 are formed of a cylindrical rod with a length preferably between 5 and 10cm
  • the rod can have a planar or polygonal section without changing the invention.
  • the upper end of the arms 5 is connected to a suspended body 6 via an axis of rotation 10 of the suspended body 6.
  • the suspended body 6 comprises an upper end in the form of a handle and an enlarged lower end forming the heel grip 13 intended for to rest on the rear curb of the ski boot in order to block any vertical movement of the heel of the ski boot.
  • the handle of the suspended body 6 can be actuated by a user in order to tilt the suspended body 6 around the axis of rotation 10 between an open position where the handle is in a low position and the heel of the shoe is free of all. movement and a closed position in which the handle adopts a high position and the heel grip 13 rests on the rear curb of the ski boot so as to vertically block the ski boot.
