Definitions

  • the present invention relates to an alpine ski boot, comprising a rigid shell, of which a shell bottom is surmounted by an at least partially articulated rod on the latter, having at least a front part and a rear part, and itself comprising opening means to allow the passage of the foot, a rod closure assembly on the lower leg comprising a clamping system with at least one traction element at least partially surrounding the rod to be tensioned by at least a tensioning device, fixed on at least one of the constituent parts of said rod.
  • the invention relates to means for immobilizing the rod in an anteroposterior direction constituted by a control member acting on an oscillating lever, around a transverse axis of a rear part of the rod, in two positions, one in which a lower end portion of the lever abuts against a rear stop of the bottom of the shell at the heel or of a position of inclination chosen towards the front of the rod, corresponding to a active position for skiing, and the other in which said lower part escapes the rear stop of the bottom of the hull to release the rod from any angular positioning constraint, the control member then acting on another part of the lever oscillating against an elastic member.
  • the manual locking means consist of a part movable in vertical translation at the upper end of an arm of the rocker, which can be actuated manually in an upward sliding movement, to extend said upper end of the scale, and to cooperate with a notch formed in the upper part of a cutout of the rod to keep the rocker in the unlocked position.
  • a sliding control of said moving part has the effect of releasing it from the upper notch and allowing it to pivot, under the action of an elastic member, so that the lower end of said rocker comes into abutment on the abovementioned stop formed at the rear of the bottom of the hull for an active position.
  • the moving part In order to allow the moving part to move in translation, in one direction or the other, it has a projecting part constituting an external gripping member without which any control would be impossible.
  • Such locking means have a certain number of drawbacks, one of which is that, whatever the position of the movable member, when locked or unlocked, the external gripping member must always remain protruding to allow its access, and thereby constitutes an aggressive protruding part, likely to cause incidents.
  • Another drawback appears on the conceptual level, because it is necessary to provide, on the one hand a relatively bulky rocker because it supports the movable member and the gripping member which is integral therewith, and on the other hand a notch higher to spare on the rod.
  • this system always involves two maneuvers to achieve stable unlocking of the upper of the shoe, namely a rectilinear pushing movement perpendicular to the upper to rotate the rocker in a release movement of its lower end of the stop, and a pushing movement also rectilinear substantially parallel to said rod to engage the movable part under the upper notch.
  • the stop means is housed in a recess in the rod and has the form of a lever with two arms pivoting about an axis mounted in the rod while the control member is pivotally mounted outside the rod, near the end of one of the arms of said stop lever.
  • the unlocking of the rod is effected by tilting towards the outside of the control member which, coming into pressure on the corresponding arm of the stop lever, causes the release of the latter from its stop on the bottom of the hull.
  • To relock the rod in the ski practice position it is then necessary to bring the control member against the rod to allow the stop lever, under the action of the elastic return force, to be placed in position d 'commitment to its stop on the bottom of the hull.
  • the immobilizing device has a lever, integral with the upper, which is capable of abutting on an element of the shell of the shoe.
  • a lever is actuated from an external cursor capable of moving linearly and acting angularly on the position of the lever, from an end articulation point, or central.
  • this device has the disadvantage of being prominent on the rod at its rear part, and this, in a permanent and variable manner since the cursor is capable of being moved in translation. Furthermore, it always involves a voluntary maneuver on the part of the skier to go from the unlocked position to the locked position for skiing. Still, the momentary unlocking operation with the possibility of automatic relocking is not possible.
  • Another object of the invention is to provide a device whose control member is inserted in the volume of the rear part of the rod; for this purpose, the control member on the one hand, is accessible either by its periphery or by its visible face, and on the other hand, it affects a unique position on the rear part of the rod whatever the maneuver carried out, permanent locking, momentary unlocking, or permanent unlocking.
  • the alpine ski boot has a shell bottom surmounted by a rod which has a front part and a rear part obtained in one or more parts, the rear part of said rod on the one hand being at least partially pivoting in the postero-anterior and / or antero-posterior direction and on the other hand, comprising an immobilization device with respect to said active shell bottom for at least one of said directions of pivoting by means of a abutment and / or attachment zone obtained on said bottom of the hull.
  • the immobilization device can be operated via a control member of an oscillating lever pivoting on the rear part of the rod around a transverse axis and subjected to the action of a return spring, which member has, relative to the rear part of the rod, an external gripping part and an internal part acting on the oscillating lever thus subjected in pivoting relation to the abutment zone of the bottom of the hull.
  • the shoe is characterized by the fact that the control member of the oscillating lever is a rotary member able to pivot in a co-axial housing forming a bearing, formed in said rear part of the upper, and in which is fixed, free to rotate. , said rotary member, independently of the oscillating lever, the internal part of said rotary member acting by means of a cam cooperating with a feeler member on the oscillating lever.
  • a preferred characteristic of the invention resides in the fact that the cam is constituted by a cylindrical part centered on the rotary element, whether it is integral with the end of the internal part of the latter or with the oscillating lever. It is obvious that a feeler member intended to cooperate with the cam is then provided on the part which is not provided with said cam. Furthermore, the cam has on its cylindrical periphery at least one ramp with a progressive profile which extends from a low point of probing to a high point extending by a zone for retaining the probing member.
  • the difference in height between the bottom and top probing points is determined as a function of the engagement of the oscillating lever on the abutment or attachment zone obtained on the bottom of the hull and is at least sufficient to cause, by means of the feeler member pivoting of said oscillating lever at least corresponding to that of its engagement on said shell bottom and obtaining the unlocking of the upper of the shoe.
  • the cam has two progressive ramps each extending from the bottom point of the latter to a common retaining area where they meet.
  • the actuator of the immobilization device associated with such a cam can thus be actuated indifferently in both directions of rotation in order to cause the unlocking of the upper of the shoe relative to the bottom of the shell.
  • the latter comprises from the bottom point and on one side, a progressive ramp as described above and on the other side, a vertical wall or abutment surface against which abuts the probing organ.
  • the maneuvering member of the immobilization device can thus be actuated only in a direction of rotation corresponding to that in which the ramp extends.
  • the cam is obtained with two asymmetrical ramps which extend from and on either side of the low point.
  • one of the ramps is then intended to allow permanent unlocking and the other ramp, to allow momentary unlocking for this purpose, the first ramp ends at the high point of unlocking of the cam by a retaining zone of the feeler member while the second ramp extends at least up to the height of the high point of the first ramp but does not include a retaining zone for the feeler member.
  • the device for immobilizing the rod can be unlocked and its return to the initial locking position can be carried out automatically as soon as the operating member of said cam is released;
  • the cam and / or the operating member can advantageously be equipped with an elastic return element.
  • the unstable cam release ramp can be provided relatively inclined so that, under the pushing effect of the return spring of the oscillating lever, the contact reaction of the feeler member on the latter promotes its return to the initial position on the low point as soon as the member is released maneuver.
  • the rod immobilization device can be provided to immobilize the latter in the only antero-posterior pivoting direction or in both antero-posterior and postero-anterior pivoting directions relative to the bottom of the shell.
  • the oscillating lever comprises an end part which cooperates, for example with a stop zone obtained on the bottom of the hull; in the case of immobilization in both directions of pivoting, the oscillating lever comprises a lug or latching pin which cooperates with a corresponding notch made in the bottom of the shell, when the rear part of the rod is brought into the active position of skiing.
  • the light extends in the vertical direction above the latching post over a certain length determined by the thickness of the latter and the desired travel stroke.
  • the shoe 1 designated overall, and represented in FIG. 1, is of the "rear entry" type.

  • a clamping system at three points 7a, 7b, 7c, and for closing the rod 2 on the lower leg of the skier comprises, in a manner known per se, three separate tensioning levers 8a, 8b, 8c which subject in tension traction elements such as cable loops 9a, 9b, 9c partially surrounding the rod 2 at its front part to be tensioned by said tensioning levers 8a, 8b, 8c, fixed for example on the side wings coming from the rear cover 4 for levers 8a and 8b and on the front of the shoe for lever 8c.
  • the shoe 1 is provided with an immobilizing device 35 of the upper 2, acting only in the anteroposterior direction; this immobilization device has a control member 10 acting on an oscillating lever 11 around a transverse axis 12 fixed in the rear part of the rod 2; the lever 11 oscillates in two positions, one in which a lower end portion 11a of the lever 11 abuts against a rear stop 13 of the bottom of the shell 5 at the heel for a position of inclination towards the front of the rod, corresponding to an active position for skiing, and the other in which said lower part 11a escapes the rear stop 13 of the bottom of the shell 5 to release the rod from any angular positioning constraint, a member rotary control 10 then acting on another part 11b opposite the end 11a of the oscillating lever against an elastic member 14, which elastic member is disposed in a housing 15 formed in the lower part 11a of the lever 11 and acts in reaction against a lower part 16a of a stiffening beam 16 constituting the wall of the
