Definitions

  • the invention relates to a set of two retaining elements provided for retaining the boots of a skier on a pair of gliding boards, in particular on a pair of skis.
  • the invention also relates to a set of two retaining elements associated with a set of two right and left boots for each of a skier's feet.
  • the stiffness of the spring is adjustable, so that the shoe is released from the fastening element for a stress exceeding a determined stress threshold.
  • This threshold is commonly referred to as the trigger threshold.
  • the shape of the front and rear toe caps of the shoe has been standardized.
  • the standard in application has the reference ISO 5355.
  • the fastening elements are designed to be compatible with the standardized zones of the shoe and to ensure the release of the shoe at release values determined.
  • a shoe is retained by a front retaining or fastening element, the jaw of which is movable at least laterally towards the inside or the outside of the foot.
  • the jaw of the retaining element is intended to trigger, that is to say to release the boot during an excessive torsional stress exerted on the skier's leg.
  • Current bindings have a trigger threshold generally equal inwards and outwards of the foot.
  • fastening elements which have a different triggering threshold according to the direction of tilting of the jaw.
  • Such elements are for example described in French patents FR 1 503 847, 1 503 848, 1 503 849, or also in the German patent application published under the number 18 07 074.
  • the problem posed by the invention is to improve the operating mode of the existing retaining elements. It consists in particular in providing the retaining elements with an asymmetric trigger threshold, and in improving the operation of such retaining elements with an asymmetric trigger threshold.
  • Each retaining element has a shoe retaining jaw movable laterally, on both sides, towards the inside or outside of the ski, against the return force of a spring.
  • the jaw and the spring are provided to release the shoe beyond a determined triggering threshold.
  • Each retaining element is additionally equipped with an adjustment mechanism, which allows the triggering threshold of the retaining element to be adjusted asymmetrically, according to the direction of movement of the jaw, and a button or control lever which allows the adjustment mechanism to be actuated from the outside.
  • the skier can adjust at will the triggering threshold of its retaining elements in a different manner depending on whether they release the boot inward or outward from the foot.
  • buttons so that the triggering threshold of each of them is lower for a release of the shoe towards the outside of the element than for a release towards the inside of the element.
  • the retaining elements and the shoe have visual cues which cooperate together to visualize the position in which each button must be placed. Indeed, if we can easily reverse the right and left skis, it is not reasonable to exchange the right and left shoes.
  • the shoes therefore carry visual cues which are for example symmetrical, according to which the buttons of the two retaining elements must be adjusted, so as to be somehow polarized as the right element and the left element, respectively.
  • the shoes and the retaining elements have mechanical marks which allow the engagement of the shoe in the retaining element only if the control button is placed in the suitable position corresponding to the position of the element. retainer, right or left.

  • the wings include a sole clamp which ensures the vertical retention of the shoe, in addition to the lateral retention.
  • the jaw could have another nature, in particular being in one piece, connected integrally to a body mounted to pivot around a central pivot. Many known constructions are possible.
  • the jaw At rest, the jaw has a position substantially aligned with the longitudinal axis defined by the ski. In the illustrated case, at rest, the wings 7 and 8 are closed towards the median longitudinal axis which is shown diagrammatically by its trace 11 in FIG. 2.
  • the body 3 of the retaining element houses a spring 12, to which are transmitted the stresses which the shoe exerts on the wings of the jaw, and which, in return, exerts on the wings an elastic restoring force in the direction of their respective rest position.
  • the spring is connected to the jaw by a movement transmission link.
  • connection between the spring and the wings of the jaw comprises a longitudinal rod 13 which is cylindrical.
  • the tie rod is engaged in the turns of the spring. It has at its front end a stop washer 14 against which the front end of the spring bears.

  • the screw 15 is accessible from the front of the retaining element through an opening in the cover.
  • the spring bears against a support wall 18 which is integral with the body or its base.
  • the support wall 18 also serves as a stop for the returns 7a and 8a of the wings, for rotation of the wings inwards. This position in abutment against the support wall defines the rest position of each of the wings.
  • the tie rod crosses the wall 18 and opens rearward between the two wings. At this level, it has a part 20 of smaller diameter, with a head 21. At the birth of this part of smaller diameter, the tie rod has a shoulder 22. On the part of smaller diameter are mounted a ring 24, on the side of the shoulder 22, and a floating rocker 25 on the side of the head 21.
  • the floating rocker is wider than the head 21, and its dimensions are such that it gives the returns 7a and 8a of the wings a surface d 'support by which the returns of the wings can urge the tie back and forth against the return force of the spring.
  • the part 20 of smaller diameter is an independent element which is assembled for example by screwing or any other means suitable for the rest of the tie rod.
  • the rocker 25 is held on the part 20 of the tie rod, pressing between its head 21 and the returns 7a and 8a of the wings.

  • the assembly of the rocker and of the ring is provided so that, at least at rest, the ring can pivot freely around the part 20. That is to say that the rocker and the ring are mounted on the tie rod, between the head and the shoulder 22 with a slight play in a longitudinal direction.
  • the rocker 25 is floating, that is to say it can oscillate in a horizontal plane, depending on the position and the displacement of its various supports.
  • the rocker has a large central opening 27 of rectangular shape.
  • the width of this opening is greater than the diameter of the part 20 of the tie rod, and, preferably, this part 20 has a flange 28 with a rounded edge, the outside diameter of which is substantially equal to the width of the opening. 27.
  • This flange serves to support the oscillation of the rocker, which will be described in more detail later.

  • the rocker drives the head 21 of the tie rod, but this time, the rocker rests by reaction not more against the ring 24, but against the return 8a of the other wing. Indeed, the rocker cannot find a support against the ring 24, because of the recessed area 30.
  • the wing 8 is retained by the support wall 18.
  • the rocker 25 no longer directly transmits its movement to the tie rod, it functions as a lever, which pivots on its support on the return 8a. Given the difference in the lever arm, the restoring force that opposes the opening of the wing is multiplied. The opening of the wing 7 is facilitated in this position of the ring 24.
  • the zone 30 is sufficiently set back so that the wing 7 releases the shoe before the rocker 25 reaches the bottom of the zone 30. In this way, the rocker 30 remains in abutment against the return of the wing 8 , and the multiplier effect is maintained.

  • the lever may have any suitable means, for example small bowls 39 provided for receiving the tip of the ski pole.
  • the assembly is designed so that a determined angle rotation of the control lever 40 causes the ring 24 to rotate a quarter turn on one side or the other from its median position.
  • the lever 40 is visible in Figure 1 above the cover. It is shown in its middle position which corresponds to the middle position of the ring 24.
  • 40a and 40b have identified the two directions in which the operating lever must be oriented in order to bring the ring 24 into one either of the so-called polarization positions of the retaining element which produce a release threshold for the asymmetrical shoe, lower on one side than on the other.
  • the ring 24 is mounted on the part 20 of the tie rod with a slight play, so that its rotation can be controlled without significant effort when the element is in the rest position.
  • the ring 24 is actually biased against the shoulder of the tie rod only when a retaining wing of the shoe is biased.

  • the skier leaves the operating levers in their position.
  • the respective orientation of the levers is suitable or not. If it is suitable, it does not modify the setting of the operating levers, in fact, the retaining elements are correctly polarized. If the levers are not in the correct position, rather than inverting the relative position of the skis, the skier simply reverses the orientation of the levers. In doing so, it brings back each of the elements of retained in a correct position. This maneuver is carried out in a simple manner, and does not require any manipulation of the skis.

  • the two inclined parts 131b and 131c of the ramp serve to lower one or the other of the latches when the button is brought back from a lateral position of polarization to the middle position.
  • the retaining element is intended to form an assembly with another identical retaining element.
  • the operating buttons must be adjusted either in the middle position, or in symmetrical positions corresponding to a lower trigger threshold for a release of the shoe corresponding to a twist of the leg in the direction in which the foot is driven towards the interior.
  • the button 130 can have any suitable means, for example a small bowl 135 provided for receiving the tip of the stick.
  • the shoes used with the retaining elements may have a coding mark which encourages them to adjust each of the buttons in the appropriate position.
  • FIG. 26 represents a retaining element 141 which is of the same type as that of FIG. 1, with in particular the spring 12, the tie rod 13, the wall 18, the rocker 25 and the ring 24.
  • the difference is that the rotation of the ring 24 is controlled electrically, not mechanically.
  • the ring 24 is here driven in rotation by an electric motor 142 which drives a toothed wheel 143 whose teeth are engaged on the grooves of the ring.
  • the motor is fixed for example to the wall 18. It is of any suitable type, and for example, it is provided for example to make rotations with a pitch corresponding to a quarter turn of the wheel toothed.
  • the rotation of the motor is controlled by a switch, the movable part of which has three stable positions, and is at least partially accessible from the outside, for example above the cover of the retaining element.
  • a switch is represented in FIG. 27 under the reference 145.
  • This switch has a body 146 which is fixed to the cover of the retaining element, and a movable part 147 which is oriented in a transverse direction, and articulated around a longitudinal axis. Above the cover, the mobile part has two open "V" shaped faces.
  • Figure 28 shows the movable part in its middle position, which corresponds to the middle position of the ring.
  • Figure 29 shows the movable part in one of its stable lateral positions. This position is for example imposed by pressing on one of the faces of the movable part, by means of the stick.
  • the switch controls the rotation of the motor 142 in order to rotate the ring 24 towards the polarization position which is assigned to it.
  • the position of the movable part of the switch is also indicative of the polarization of the retaining element. In other words, depending on the face of the switch which is pressed towards the cover, it is possible to see whether the retaining element is polarized as a right element or as a left element.
  • the switch 145 and the motor are coupled by electrical means, in particular a battery and connectors. These means are of a known type and will not be described in detail.
  • the present description is not limited to the various embodiments and variants which have been described, and numerous variants are possible.
  • the invention can be adapted to other known constructions of retaining element than those which have been described.
  • the operating buttons could be placed in front of the retaining element, on the side, or in any other appropriate zone.
