Definitions

  • the subject of the present invention is a ski boot consisting of at least one lower part intended to surround the foot and the heel and a rod articulated on this lower part and comprising, at the rear, means of connection between the upper and the lower part, these connecting means comprising a locking member for fixing or releasing the rod in rotation relative to the lower part, means for adjusting the inclination of the upper relative to the lower part of the shoe by a screw / nut system, an elastic element and means for adjusting the elasticity of this elastic element, the connecting means comprising a bar in two parts connected to each other by a threaded part, extending parallel to the back of the rod and the lower end of which is attached to the lower part of the shoe, a control button being integral with the upper part of the bar for adjusting the length of the bar.
  • a shoe provided with rod locking means which can be unlocked to allow the oscillation of this rod and means making it possible to adjust the inclination of the rod in the locked position is described in patent FR 2 491 304.
  • the device used comprises a lever articulated at its end on a stirrup secured to the inner part of the shoe and at an intermediate point, by a sliding nut carried by a threaded rod forming part of the lever, at the end of a link articulated on a stirrup secured to the rod.
  • the threaded rod is provided with gripping means making it possible to rotate it to move the sliding nut. It has been envisaged to replace the link by an adjustable elastic connection as described in US Pat. No. 3,619,914.
  • a ski boot with an articulated rod comprising connection means of adjustable length between the rod and the lower part of the boot, arranged so as to allow the rod to be released. in the on position.
  • the connecting means consist of a first threaded bar provided with two threads with opposite pitch screwed respectively in the lower part and in a second bar mounted in a cage mounted sliding on the rod and capable of being blocked on the rod by means an articulated lock on the rod.
  • the cage contains a helical spring surrounding the second bar and compressed between the bottom of the cage and a nut mounted at the end of the second bar and used to adjust the spring preload. Ways bonds are relatively complicated, delicate and sensitive to snow and ice. They are also highly prominent and the articulated lock forms a projection capable of being accidentally hooked, causing untimely and dangerous release of the upper of the shoe.
  • the present invention aims to achieve a more compact and simpler device for fulfilling the three functions mentioned above, namely locking and unlocking of the upper of the shoe, adjusting the inclination of this upper and adjusting the resistance to bending of this rod.
  • the device must not include any articulation or lever projecting in the locked and unlocked positions and / or driven in oscillation when walking.
  • the shoe according to the invention is defined by claim 1.
  • the locking member is preferably constituted by an elastically mounted element or working elastically in bending, but it could also perform a simple rotation around the bar.
  • the device can be produced in a particularly compact manner by providing control of the rigid sleeve sliding through a cutout of the control member of the locking member.
  • Figure 1 is a partial perspective view of a portion of the rear of the shoe showing the connecting device in the locked position.
  • Figure 2 is a view of the same connecting device in the locked position, but without the shoe.
  • FIG. 3 is a view in axial section of the device shown in FIG. 2.
  • Figure 4 is a view similar to that of Figure 1, but showing the connecting device in the unlocked position.
  • FIG. 5 represents the device separated from the shoe for adjusting the inclination.
  • the shoe is a shoe similar to the shoe represented in FIG. 1 of patent FR 2 491 304 and it includes, like it, a lower or lower part of the shell 1 surrounding the foot and the heel and a rod 2 articulated on the lower part.
  • the ends of the two upper loops 3 and 4 have also been shown diagrammatically for tightening the rod.
  • This rod 2 has a flat back 5 provided with a rectangular cutout in which is fixed a metal cradle 6 of rectangular shape and having in particular two parallel vertical side walls 7 and 8.
  • the connection device shown alone in FIGS. 2 and 3, is housed in cradle 6.
  • This connecting device comprises a cylindrical bar 9, the lower end of which is provided with a hole 10 by which the bar 9 is attached to the bottom of the shell 1 by means of a pin 11.
  • the upper end 9a of the bar 9 is threaded and is screwed into a rod end 9b secured to a button 12 which can be actuated manually.
  • the bar 9 is therefore of variable length.
  • Around of the bar 9 is mounted a ring 13 coming to bear on the bottom 6a of the cradle 6 which constitutes a stop for the connection device.
  • the ring 13 is integral with a rigid cylinder 14. Above this cylinder 14 is placed a cylindrical sleeve 15 of elastic material not compressible in volume and also crossed by the bar 9.
  • a lock 16 Between the button 12 and the elastic sleeve 15 is mounted a lock 16 between a square plate 18 and the bent part 33a of a plate 33 extending parallel to the bar 9.
  • the plate 18 and the bent part 33a play the role of washers freely mounted on the bar 9.
  • a rigid sleeve 19 Around of the elastic sleeve 15 is mounted a rigid sleeve 19 of internal diameter just sufficient to allow this sleeve 19 to slide on the elastic sleeve 15 to modify the length of the part of the elastic sleeve 15 located outside of the sleeve 19, so as to adjust the elastic resistance of the elastic sleeve 15 as described in patent EP 0 206 394.
  • the sleeve 15 is for example made of rubber.
  • the rigid sleeve 19 is integral with a button 32 capable of being displaced according to the double arrow F1 above the plate 33.
  • the latch 16 consists of two arms 20 and 21 hinged together and kept apart in V by a spring 35. These arms are provided with pins 22, 23 respectively directed laterally outwards.
  • the latch 16 cooperates with a control member 24 consisting of a generally rectangular piece slidably mounted on the cradle 7.
  • the control member 24 has a cutout 25 of triangular shape, the two sides 26 and 27 constitute ramps for actuating the latch 16.
  • the triangle 25 is truncated and the ends of the ramps 26 and 27 end respectively in housings or notches 28 and 29.
  • the lugs 22 and 23 of the latch 16 are engaged respectively in rectangular cutouts 30 and 31 provided in the walls 7 and 8 of the cradle 6.
  • the rotation of the button 12 has the effect of lengthening or shortening the length of the bar 9, that is to say the distance between its point of attachment 11 to the bottom of the shell 1 and the latch 16 and consequently of adjust the inclination of the upper 2 of the shoe.
  • the connecting device is then folded back into the cradle 6.
  • the button 32 makes it possible to move the rigid sleeve 19 along the elastic sleeve 15 and consequently to modify the length of the elastic part of the sleeve 15 situated outside of the rigid sleeve 19, liable to deform by expanding under the effect of axial compression, that is to say to modify the hardness of the elastic damper constituted by the elastic sleeve 15 when the upper 2 of the shoe is biased backwards.
  • the movable sleeve 19 can be locked in three different positions by means of a rotary connection between the sleeve 19 and its button 32 and an oblong intermediate part 36, with rounded ends, cooperating with a slot 37 of the plate 33 connecting three circular cutouts 38, 39 and 40 of diameter corresponding to the length of the oblong part 36.
  • the button 32 By turning the button 32 it is possible to orient the oblong part 36 parallel to the slot 37 so that it is possible to move this oblong part 36 from one end to the other of the slot 37.
  • the button 32 is locked in this position. It would of course be possible to increase the number of locked positions.
  • the lock 16 could be executed in many variants. It could for example consist of a single flexible V-shaped piece or of a circular piece rotatably mounted around the bar 9 and provided with two radial fingers, one constituting the lock and the other a cooperating actuating arm with an oblique groove of the control member 24, the displacement of which would cause the bolt to rotate.
  • the lock could also consist of two rods working radially in translation and each provided with an arm perpendicular to the rods and cooperating respectively with two oblique grooves of the control member 24.
