Definitions

  • the invention relates to a shoe retention element on a ski.
  • the invention relates to a front retaining element which is designed to releasably retain the front of a shoe.
  • the element has a jaw which is movable against the force of reminder opposed to it by an elastic return means, for example a spring.
  • the invention relates to those whose trigger is asymmetrical, i.e. they release the shoe more easily on one side than on the other.
  • a skier's leg is able to endure higher twists for forefoot rotation outward only for rotation to the other foot. So it appeared interesting to make retaining elements that take into account this dissymmetry.
  • Patent applications published under the numbers FR 1 503 849, FR 1 503 847 describe such elements which release the shoe asymmetrically.
  • An object of the invention is to improve this type of retaining element by making its asymmetrical functioning by simple modifications of its construction.
  • the retaining element according to the invention as described in claim 1 comprises a base provided for be secured to the ski, a body connected to the base, the body having two axes hinge for two retaining wings, the retaining wings having a return wing beyond the hinge axis, a return spring housed in the body, a connecting member between the spring and the wing returns. It also includes a asymmetrical member in the connection chain between the spring and the wings.
  • Figure 1 shows a side of a traditional retaining element of the type concerned with the invention.
  • Figure 2 is a sectional side view of the retainer of Figure 1.
  • Figure 3 shows two half views of the retainer of Figure 1 cut by section planes located at different altitudes.
  • Figure 4 illustrates in top view and in section a retaining element according a first embodiment of the invention.
  • Figure 5 relates to another embodiment of the invention.
  • Figure 6 illustrates the operating mode of the element shown in figure 5.
  • Figure 7 relates to another embodiment of the invention.
  • FIG. 8 represents in perspective the intermediate flap of FIG. 6.
  • FIG. 9 illustrates the operating mode of the element in FIG. 7.
  • the front fixing element 1 represented in FIGS. 1 to 3 is known for the essentials according to the French patent application published under the number FR 2 640 516.
  • the base has a "U" shape open towards the rear, with two lateral branches 3a and 3b.
  • the body is movable vertically relative to the base by a link deformable, located in zone 9 at the junction between the body and the base.
  • the body and the base are connected continuously by this deformable zone and form a monobloc element.
  • the body 2 carries a jaw 4 retaining the front end of the shoe.
  • the jaw 4 comprises two lateral retaining wings 5 and 6, respectively articulated to the body 2 around axes 7 and 8.
  • the jaw 4 comprises also a sole clamp 12 for vertical retention of the shoe.
  • the wings 5 and 6 are movable in response to the stresses of the shoe, against the return force applied to them by a spring 15.
  • the spring 15 is housed in the body. It acts on a piston 16 also housed and guided in the body for a longitudinal translational movement.
  • the figures show that the piston is housed and guided in a housing 17 of the body, and that the spring is engaged inside the piston. Its front end is pressed against the bottom of the piston, located on the front side of the fixing element.
  • a screw 20 whose head is retained at the front of the body, moreover passes through the piston and the spring, and has a nut 21 at the rear which retains the rear end of the spring.
  • a rotation of the screw drives the spring in translation, which adjusts the initial compression of the spring.
  • the wings 5 and 6 have beyond their axis of articulation to the body 7 and 8 a return 5a, 6a, which drives the piston 16 rearward, bearing against a shoulder 23 located in the upper rear part of the piston 16.
  • element 1 has a mechanism for compensation which alleviates the restoring force that the spring 15 exerts on the wings 5 and 6.
  • This mechanism comprises an articulated rocker 30 which is partly housed between the branches 3a and 3b of the base 3.
  • the rocker is articulated around an axis 32 carried by these branches.
  • the rocker 30 has an approximately horizontal arm 33 which is accessible on the rear of the fixing element between the branches 3a and 3b of the base.
  • the rocker 30 also has an approximately vertical arm formed by two lateral pads which pass on each side of the piston 16, and which each bear on a shoulder 37 which the piston has under the shoulder 23 wings. Only the shoe 35 is partially visible in the figures.
  • a connecting rod 36 also connects the rocker 30 to the rear part of the body 2.
  • the articulation of the rod 36 to the rocker 30 is located in front of the axis 32.
  • the rod transmits to the rocker 30, and therefore to the piston 16, the elevation movements of the body which occur in particular during a vertical stress on the shoe in the jaw.
  • the element has a support plate 40 provided behind the jaw to receive the front of the shoe sole.
  • the front part of the pedal is vertically movable, and overhangs the horizontal arm 33 of the rocker 30.
  • a spring 51 ensures the elastic return to the top of the front of the pedal.
  • FIG. 4 illustrates a first embodiment of the invention. according to this mode of implementation, one of the two wings has a shorter return than the other so that the wings stress the piston with different lever arms.
  • FIG 4 there is shown a retaining element with, the return 45a of wing 45 shorter than the return of the other wing 46.
  • Wing 45 attacks the piston with a shorter lever arm, where it follows that this wing 45 will be easier to open than the other wing 46.
  • the axis offset could also have two components, inward and forward, to both increase the lever arm with which the shoe stresses the wing, and decrease the lever arm with which the wing attacks the piston.
  • FIG. 5 illustrates another variant implementation of the invention.
  • the wing which has the lowest resistance to opening, in the occurrence of wing 48 has a return of wing 48a whose bearing face against the piston shoulder is cut like a beveled ramp which has a support face oblique to a longitudinal direction.
  • Piston 49 has a support shoulder 50 which is designed to cooperate with the face support of the ramp so that the contact surface between the wing return and the shoulder moves along the beveled ramp during the rotation of the wing.
  • the shape of the support shoulder takes into account the shape of the ramp the wing, and also takes into account that the wing return moves in a circular movement, but that it animates the shoulder of a movement directed according to a longitudinal direction.
  • the shoulder has a leading edge for the relatively fine wing return and round shape.
  • the wing return slides on the shoulder of the piston, and, therefore, in a longitudinal direction, the wing return has a linear movement of greater amplitude than the linear movement of the piston that the return drives.
  • the release of the shoe from the side of the wing 48 is obtained for compression of the spring weaker than on the side of the other wing. We can indeed consider that this release occurs for a wing opening of determined angle.
  • Figure 6 shows the wing 48 in the open position, with its return 48a which has slid along the shoulder due to its rotation around the axis of the wing.
  • any other suitable shape is suitable for the surfaces of wing beak and shoulder contact, provided that in one direction longitudinal, we get a relative movement of the return relative to the piston.
  • the other wing 52 of the retaining element has a traditional support with a wing return 52a bearing against a transverse shoulder 53 of the piston.
  • FIG. 7 shows another embodiment of the invention.
  • the piston 60 has in its upper part a transverse support shoulder 61, which provides support for the two returns 62a and 63a of the wings 62 and 63. Between the transverse shoulder and the wing returns is interposed a movable flap 65.
  • the flap is more particularly visible in FIG. 8.
  • On the wing return side it has a bearing face with two bearing zones 66 and 67, substantially in line with one another, one for each return wing.
  • the flap carries two support zones 68 and 69, which form between they have a dihedral angle greater than a flat angle, so that a portion of the flap is beveled.
  • the faces 67 and 69 are substantially parallel to each other. Between zones 68, 69, the flap carries an edge 70 or all other suitable means of bearing against the transverse shoulder 53 of the piston, and articulation around a vertical direction. The edge is shifted to the side where the flap is beveled without however exceeding the level of the wing return support 62a against zone 66.
  • the shoulder has a groove or any other appropriate means to receive the edge 70 of the shutter. Any other means of support and articulation between these two elements also suitable.
  • the wings 62 and 63 each have a support stop which defines their rest position.
  • This stop is formed for example by the supports of the face internal 72, 73 of the wings against stops integral with the body. These stops are not not shown in the figures. In known manner, these stops can be formed by vertical partitions which connect the upper part and the part lower body.
  • the spring In the rest position, the spring returns the wings to their rest position.
  • the flap 65 is held with its face 69 in abutment against the transverse shoulder 61.
  • the return wing 63a carries with it the flap, the two parallel faces 67 and 69 of which find pinched between the wing return and the transverse shoulder. Movement wing return in a longitudinal direction is transmitted directly to the piston.
  • the displacement of the piston and the resistance force that the piston opposes the wing opening are reduced by the ratio of the lever arms between the different shutter support.
  • the wing 63 which is located on the side of the bevel of the flap opens more easily than the other wing.
  • the position of the edge relative to the support zones of the two wing returns determines the ratio of the lever arms and therefore the ratio of decrease in strength.
  • the bevel angle of the flap determines with the position of edge 70 the opening stroke of wing 62 beyond which face 68 of flap 65 bears against the shoulder. At this stage of tilting of the flap, the movement of the flap becomes equal to that of the piston.
  • the face 68 of the flap could be entirely or partially curved, so as to have a variable speed decrease between the speed linear of the wing return, and that of the piston.
  • the face 66 could also be curved or have a ramp shape for compensate for the tilting of the flap 65 and the relative movement between the wing return 62a and the flap 65 during the opening of the wing.
  • the piston could be replaced by a tie rod or any other appropriate force transmission organ guided with respect to the body.
  • each of the elements present an asymmetry of the same nature, which is exerted in reverse, that is to say, for example, which reduces the retaining force of the outer wings.
