Definitions

  • the invention relates to an alpine ski binding element, intended to retain a boot bearing on a ski, and to release it in the event of excessive stress.
  • Each retaining element has a jaw carried by a body, which is movable against the restoring force exerted by an energy spring, generally a compression spring.
  • the invention relates more particularly to a front fixing element.
  • the front binding element reacts to a lateral stress on the front end of the shoe. Such stress results from a stress in pure torsion on the skier's leg.
  • One of the aims of the invention is to provide a fastening element which releases the shoe, in particular in the case of a pre-twist fall where the lateral component is relatively weak.
  • Another object of the invention is to propose a fixing element which is relatively simple to construct.
  • the support plate is movable for a rolling movement
  • connecting means sensitive to the rolling movements of the support plate connect the support plate to at least one of the movable members of the fastening element, to lower the resistance force that the shoe must overcome in order to be released laterally by the jaw, then cause the jaw to tilt freely, beyond a rolling movement of determined amplitude produced by the support plate .
  • Figure 1 shows a side view in section of a fastening element according to a non-limiting implementation of the invention.
  • FIG. 2 represents two half top views in section through planes situated at different altitudes.
  • Figure 3 is a top view, in section of the fastener of Figure 1 at its base.
  • Figure 4 is a perspective view of the rocker.
  • Figures 5 and 6 are views similar to Figure 3 and illustrate the operation of the device.
  • Figure 1 shows a fixing element 1 which, apart from the support device and the base which will be described below in more detail, has a general structure known for example from the patent application in France published under the number 2 640 516. However, only the organs of this fixation essential for the understanding of the present invention have been represented.
  • the fastening element 1 comprises a body 2 connected to a base 3 which is connected to the ski by any suitable means and for example by screws.
  • the body 2 carries a jaw 4 for 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 also includes a sole clamp 12 for vertical retention of the shoe.
  • the wings 6 and 7 are movable in response to the stresses of the shoe, against the restoring force applied to them by a spring 15.
  • the spring 15 is housed in the body. It actuates 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 bears against the bottom of the piston, located on the front side of the fixing element.
  • a screw 20 whose head is retained by the front of the body moreover passes through the piston and the spring, and presents towards the rear a nut 21 which retains the rear end of the spring.
  • a rotation of the screw drives the spring in translation, which makes it possible to adjust the initial compression of the spring.
  • the wings 5 and 6 have, beyond their axis of articulation to the body 7 and 8, a small arm 5a, 6a, which drives the piston 16 towards the rear, bearing against a shoulder 23 situated in the upper rear part of the piston 16.
  • the base 3 which carries the body allows rotation of the body about a vertical axis.
  • the body has in its lower part a vertical pivot 18, cylindrical of revolution, which passes through a cylindrical orifice 19 of corresponding size presented by the base, by which it is guided.
  • the assembly is for example produced by a disc 22 assembled with the pivot, for example by screws, the disc having a diameter slightly greater than that of the pivot, and being housed in a shouldered recess of the base.
  • the pivot 18 is hollow, and it has a central recess 24 which opens upwards into the interior volume of the body, in particular which is in communication with the housing 17 of the piston.
  • a removable lock 54 retains the body in position aligned with the longitudinal axis defined by the base. This lock will be described later.
  • the fastening element 1 also comprises a support device 25 for the front end of the shoe sole.
  • the support device has a support plate 26 on which the shoe sole rests.
  • the plate 26 can be equipped in its upper part with any suitable coating intended to facilitate the lateral sliding of the shoe, for example a PTFE (polytetrafluoroethylene) plate. It has a width which is of the order of the width of the ski at this level.
  • the support plate 26 on which the shoe rests can oscillate for a rolling movement on either side of a nominal position in which it offers the shoe a substantially horizontal support surface.
  • the support plate is articulated in rotation about a longitudinal axis 28 located towards the middle of the width of the plate.
  • the axis 28 is carried by a stud 29 which rises from a plate 31.
  • the plate 31 extends under the support plate 26, against the upper surface of the ski. For example, it is connected to the base 3 which it extends backwards, or else it continuously extends the base 3.
  • the support plate has two vertical tabs 34, 35, in front of and behind the stud 29, which the axis 28 crosses.
  • a connecting means reacting to the rolling movements of the support plate 26 also connects the support device to the energy spring.
  • This connecting means exerts on the spring a force which decreases the restoring force which the spring itself exerts on the lateral retaining wings.
  • the shoe is released relatively more easily. This compensates in particular for friction and other effects which slow down the lateral movement of the shoe in the event of it twisting in its retaining jaw.
  • This means also actuates the bolt which retains the body aligned on the base, so as to release the body in rotation relative to the base beyond a determined displacement movement of the plate 26.
  • a rocker 40 is articulated around a horizontal and transverse axis 41 carried by the plate 31 or, where appropriate, the base 3, and located just in front of the support plate 26.
  • the rocker 40 extends over substantially the entire width of the support plate 26. It has a horizontal branch oriented towards the rear and a vertical branch oriented downwards relative to the axis 41.
  • the horizontal branch comprises two legs 43 and 44 which respectively engage under each lateral edge of the plate 26, so that the rolling movement of the plate 26 on one side or the other causes the horizontal branch of the rocker to rotate downward.
  • the rocker 41 also has a vertical branch 45 which provides at least in the vicinity of the median longitudinal axis of the fixing element a bearing face on which a longitudinal plunger 50 rests and on which it imparts its movement.
  • the pusher 50 is guided in a groove 51 of the base oriented in a longitudinal direction. Forward, the pusher 50 carries a roller 52 which rests on the curved branch 53 of an anchor-shaped part 54 forming a lock.
  • the body 55 of the anchor is carried and guided in the longitudinal direction defined by the body by the wall of the pivot 18 which it crosses right through.
  • the body 55 of the anchor 54 bears against the vertical branch 57 of a rocker 58.
  • the rocker 58 is partly housed in the recess 24 of the pivot 18, and it is articulated around a transverse axis 59 carried by the wall of the recess. Upwards, it has an approximately vertical branch made up of two forks 61 and 62 which pass on each side of the front part of the piston 16, and which are each pressing back and forth against a shoulder 63, 64, which the piston present in its rear part. These shoulders are of the same type as the shoulders 23 by which the lateral retaining wings urge the piston 16.
  • the anchor 54 also forms the removable lock retained by the body 2 in alignment with the base 3.
  • the branch 53 of the anchor is housed in a recess 66 of corresponding shape located hollow in the wall of the orifice 19 for guiding the pivot 18.
  • the shape of the recess 66 is determined so that the branch 53 of the anchor 54 is housed almost without play for a rotational movement around the axis of the pivot, but that the anchor 54 can slide in longitudinal translation under the action of the pusher 50.
  • the shoe biases one or the other of the wings 5, 6, which drives the piston 16 backwards against the restoring force developed by the compression of the spring. Beyond a determined opening, the wing releases the boot, or, if in the meantime the stress has ceased, returns the boot to the position centered on the ski.
  • the support plate 26 is subjected to rolling.
  • the support plate 26 transmits this stress to the rocker 40, by one or the other of its legs 43, 44, according to the direction of stress.
  • the rocker 40 actuates the pusher 50, which in turn pushes the anchor 54 forward.
  • the anchor 54 drives the rocker 58, which then biases the piston 16 backwards, that is to say in the same direction as the wings 5 and 6.
  • the action of the support plate 26 is added to that of the stressed wing, so that the lateral force which the shoe must overcome to open a wing and be released is reduced.
  • the increase in friction induced by the twisting of the shoe is compensated.
  • This compensation action is illustrated in FIG. 5, and it takes place as long as the branch 53 of the anchor 54 remains in its housing 66, that is to say as long as the tilting of the support plate 26 remains below a determined amplitude.
  • this rotational movement is free over a limited angular amplitude, sufficient however to cause certain release of the shoe.
  • the branch 53 of the anchor 54 circulates in one or the other of two clearances 70, 71 that the recess 66 has on each side of its mouth in the orifice 19.
  • the amplitude the angular movement is determined from the half length of the branch 53 and the length of these clearances 70, 71. These two dimensions are preferably close so that the roller 52 remains in abutment against the branch 53 during this movement.
  • the piston develops on the rocker 58 a restoring force which tends to bring the various elements of the connecting means and the support plate 26 back to their respective initial positions.
  • the contact surface between the branch 53 of the anchor 55 and the wall of the recesses 70, 71 can be arranged to create a ramp effect which facilitates the return of the body 2 in the aligned position relative to the base 3.
  • rocker 58 and the latch 54 could be controlled from the support plate 26 by two independent circuits.
  • An adjustment on the circuit of the lock would also make it possible to control the moment when the unlocking of the body occurs, that is to say to have an unlocking more or less easy.
