Definitions

  • the invention relates to a sub-assembly for the elastic return of the retaining member of an alpine binding element.
  • an alpine binding element has a member for retaining one end of the boot, which is movable against the elastic restoring force of a spring, which, in the case of the present invention, is a spring compression.
  • the retaining member transmits its stresses to the spring via a connecting means, such as a piston.
  • Another problem is to produce, simply and economically, the nut forming a stop, as well as the means for viewing the compression of the spring, while ensuring good wear resistance of this nut.
  • the elastic return sub-assembly of the retaining member of an alpine fastening element comprises a compression spring, an adjustment screw passing right through the spring, a nut forming a stopper support for one of the ends of the spring, screwed onto the threaded end of the screw, an index showing the compression of the spring, and a connecting member with the retaining member, movable parallel to the axis of the spring with the movements of the retainer.
  • the screw has, in its central part, a shoulder against which the nut abuts in the extreme position of compression of the spring, and that, in this position, the turns of the spring are still spaced.
  • Figure 1 shows, in side view, and in partial section, a front fixing element equipped with an elastic return sub-assembly according to a first non-limiting implementation of the invention.
  • FIG. 2 is a side view, in section along a longitudinal and vertical plane, of the elastic return sub-assembly which equips the fixing element of FIG. 1.
  • Figure 3 shows the sub-assembly of Figure 2 in another operating position.
  • FIG. 4 illustrates an alternative embodiment
  • FIG. 5 represents, in side view, and in an exploded manner, the various elements of the device represented in FIG. 4.
  • FIG. 1 shows, by way of non-limiting illustration of the invention, a fastening element 1, which in a known manner, has a base 2 intended to be secured to the ski, surmounted by a body 3.
  • the body 3 carries a shoe retaining member which is represented in FIG. 1 in the form of a retaining wing 4.
  • the wing is movable around an approximately vertical axis, under the action of the stresses of the shoe.
  • the movement of the wing 4 outwards causes the rearward translation in a substantially horizontal and longitudinal direction of a piston 5, against the elastic return force of a compression spring 6 which is housed in the inside of piston 5.
  • the initial compression of the spring 6 is adjusted by means of a screw 7, the head of which is accessible from the outside, at the front end of the fixing element.
  • the head 8 bears against the body 3, crosses the piston, then the spring right through.
  • the screw 7 has a threaded portion 9 on which is engaged a nut 10 forming a stop, against which the rear end of the spring bears. Means also prevent the nut 10 from following the rotation of the screw during an adjustment movement. These means will be described later.
  • the rotation of the screw 8 causes the translation of the nut 10 along the axis 11 of the screw, which results in compression or decompression of the spring 6.
  • An index 12 also moves with the nut 10. This index is visible from the outside through a transparent plate 13 which equips the upper cover of the body 3.
  • the screw 7 has, between the head 8 and the threaded portion 9, a smooth body 15, of diameter significantly greater than the diameter of the threaded portion 9, and less than the inner diameter of the turns of the spring 6
  • the difference in diameter between the smooth body 15 and the threaded part 9 creates a shoulder 16 at the border between these two parts of the screw.
  • the nut 10 is made of a molded plastic material, and it has, on the side of the screw head, a tip 18, which projects, the internal part of which is tapped, and whose outer surface is substantially cylindrical in revolution.
  • the ring 19 prevents deformation of the end piece, in particular its swelling when, following the rotation of the screw 7, the end piece 18 comes against the shoulder 16.
  • the outside diameter of the ring 19 is substantially less than the inside diameter of a turn, so that the ring engages inside the spring.
  • the ring 19 closes with a return 20, which provides a substantially vertical bearing face whose role will be explained later.
  • the nut 10 has a washer 21, of diameter greater than that of the ring, which provides a vertical abutment surface, against which the end of the spring comes to bear.
  • FIG. 3 represents the nut 10 and the screw 7 in the extreme compression position of the spring 6.
  • the shoulder 16 of the screw is located at a distance from the head such that the turns of the spring 6 are still spaced.
  • the spring can be compressed additionally in response to the movements of the piston 5 due to the opening of the wings. The spring thus retains an elastic return function whatever the position of the nut 10.
  • the piston 5 has, in its upper part, an opening 25, which is in the form of a longitudinal slot. This opening is traversed by a finger 26, which is integrally connected to the nut 10.
  • the finger 26 and the nut 10 are made in one piece by molding.
  • the finger 26 carries, at its upper end, the index 12 which makes it possible to view the state of compression of the spring. This index 12, or the upper part of the finger 26, bears on the side walls of the opening 25 of the piston, which prevents the nut 10 from being rotated during the rotation of the screw.
  • the length of the opening 25 is determined from the longitudinal stroke of the nut 10 along the screw, as well as the longitudinal stroke of the piston 5 following the stresses of the shoe on the retaining member.
  • the index is made very simply since it is made in one piece with the nut 10.
  • the index prevents rotation of the nut.
  • Figure 4 shows an alternative embodiment of the nut.
  • the nut comprises a metal insert 30, which has, in its central part, a threaded orifice.
  • a plastic element 31 is fitted onto the insert, and this element is extended upwards by a finger 32 surmounted by the index 12 which was mentioned above.
  • the index 30 has laterally, at least one, and preferably two slots 33 parallel to the axis of the screw.
  • the element 31 has one, and preferably two tongues 34 which engage in the slots 33 of the insert 30. These tongues 34 come into contact with the threaded part of the screw, and constitute a brake for rotation of the screw relative to the nut.
  • the nut shown in Figures 4 and 5, works in the same way as the nut 10 previously described, and in this case, it is the end of the insert which is located on the side of the screw head which abuts against the shoulder 16 of the screw to limit its rotational movement in the direction of compression of the spring.
  • the turns of the spring 6 are not contiguous, so that the spring still retains a certain compression stroke.
