Definitions

  • the object of the present invention is a ski boot comprising at least two parts whose edges overlap to surround the foot or the ankle and at least one closure and tensioning device for connecting these two parts, this device comprising a toothed belt secured of one of said parts of the shoe and cooperating with fastening and tensioning means integral with this same part or with the other part of the shoe.
  • a device of this type is known from patent FR-A-2,180,250.
  • the belt is notched and cooperates on the one hand with a tensioning device constituted by a unidirectional drive device working back and forth and on the other hand with a retaining pawl, the whole working, in the same way way that a jack.
  • the tensioning and hooking means are therefore completely separate and work independently of one another.
  • This device is relatively complicated and bulky and is not always easy to use. Indeed, to release the belt it is necessary to release the retaining pawl, which can require considerable force when the belt is tight.
  • the modification of the tension can only be done on the basis of one tooth at a time and these teeth must have a certain minimum dimension to guarantee good retention.
  • the tension lever has a low multiplication, so that it becomes hard from a certain tension.
  • the present invention aims to achieve a device of the type defined above, but simpler, less bulky and requiring only minimal force for its actuation.
  • the ski boot according to the invention is characterized in that the toothed belt has a helical toothing and that the hooking and tensioning means consist of a worm screw extending in the direction of the belt and provided with a manual actuation means, and by guide means holding the toothed belt in engagement with the worm, an articulation being further provided to allow the toothed belt to be moved away from the worm or vice versa,
  • the tensioning and hooking means are constituted by the same element, the worm.
  • This device is particularly space-saving, because the screw and its rod extend parallel to the surface of the shoe and the worm itself can be embedded in the thickness of the shoe.
  • the belt guide means can be raised so as to allow rapid introduction of the belt between the worm and the raised guide means, these guide means then being folded down and fixed by an ad hoc means, so as to keep the toothing of the belt engaged in the worm.
  • the worm is mounted in a lifting support on which is further mounted an oscillating lever provided with a pawl cooperating directly with a toothing formed on the worm.
  • the shoe shown in Figure 1 includes a c1> that 1 secured to the sole and intended to surround the foot, the heel and the lower front part of the ankle and a rod consisting of a front part 2 in the form of a gutter open to the rear, fixed in a known manner to the shell 1 at the height of the maléolles at two opposite points, such as point 3, around which the part 2 can oscillate slightly.
  • the rod further comprises a rear part 4, also in the form of a gutter, articulated around the points of articulation of the front part 2, this part 4 coming to fit in part 2 to surround the ankle and being foldable towards the rear to allow the introduction of the foot into the shoe.
  • These elements are made of conventional synthetic material.
  • connection and tensioning device 5 is shown in detail in FIG. 2. It comprises a belt 8 secured to the front part 2 of the rod, for example in the same material as this rod, attached to it or coming in one piece with it, and coming to surround part 4.
  • One of the faces of this belt 6 has a corresponding helical toothing 7 and cooperating with the toothing of an endless screw 8 housed in a cutout in part 2 of the rod and secured to an axis 9 housed in an extra thickness 2a of part 2 of the rod.
  • the outer end of the axis 9 carries a cylindrical head 10 of diameter greater than the diameter of the axis 9 and coming to bear against a flat surface 11 of the extra thickness 2a.
  • the head 10 ends in a fork to receive the end of a crank 12 articulated on the fork by means of an axis 13.
  • the crank 12 has a notch 14 coming to be fixed with a notch behind a projection 15 of the part 2 of the shoe in the rest position.
  • the device further comprises a guide piece 16 in the form of an elongated rectangular cover having a U-shaped profile, for example of stamped metal, the wings 17 and 18 of which are articulated in the extra thickness 2a by means of an axis 19 near the inner end of the axis 9.
  • a clamp 20 in the form of a fork with two teeth, each of the teeth of which has a rounded notch 21 on the inside which is applied on the periphery of the cylindrical head 10 when the cover 16 is folded against the shoe, as shown in the drawing, to retain this cover 16 in the folded position.
  • the cover 16 of the shoe is first moved aside, which allows the toothing 7 of the belt to disengage from the screw 8, thus allowing an almost instantaneous opening of the shoe.
  • the belt 6 is inserted as far as possible between the raised cover 16 and the screw 8, then the cover 16 is folded down.
  • the belt is then engaged with the screw 8.
  • the crank 12 is then released from its notch 15 and the screw is actuated until the desired tightening has been reached, then the crank 12 is folded again against the shoe.
  • crank 12 In place of the crank 12 it is possible to use a knob or a knurled chicken fixed at the end of the axis 9. Such an actuation allows a continuous adjustment of the tension.
  • the worm 22 is pivoted in a support 23 hinged about an axis 24 on a boss 25 of the part 2 of the shoe.
  • the worm 22 is more precisely mounted in a slot 26 of the support 23.
  • This support 23 is held in the folded position on the shoe by a notch 27 which snaps onto a spout 28 formed on the part 2 of the shoe.
  • the end 29 of the support 23 is shaped to allow the lever to be grasped to raise it, respectively to fold it down and snap it into place.
  • the toothed belt 30 is guided by a passage 31 formed in part 2 of the shoe under the spout 28 and extending, in the form of a groove, under the lever 23, so that the worm 22 meshes with the toothing 32 of the belt in the folded position, through a cutout 46 in part 2 of the shoe.
  • a lever 33 On the support 23, in the niche 26 of this, is further articulated, on the axis of the worm 22, a lever 33 provided with a pawl 34 constituted by a leaf spring, one of which ends is embedded in the lever 33 and one of its faces is supported on a bearing 35 of the lever 33 (Fig. 7), the other side being free.
  • the pawl 34 cooperates with ratchet teeth 36 cut directly on the worm 22.
  • the closing device is used as follows: the support 23 being preferably raised, the belt 30 is introduced as far as possible through the passage 31, then the support 23 is folded down. It is then sufficient to actuate the lever 33 according to a back-and-forth movement to drive the worm in a unidirectional manner in the direction of arrow F1. Once the desired tension has been obtained, the lever 33 is folded back into the position shown in FIGS. 5 and 7. To open the boot, it suffices to raise the support 23, which has the effect of releasing the belt 30.
  • This device allows a practically continuous adjustment of the tension. It is particularly compact and easy to operate.
  • the end of the strap is also hidden under part 2 of the shoe.
  • FIG. 8 Such an alternative embodiment is shown in Figure 8 in a section corresponding to that of Figure 7.
  • the parts not shown are the same as those shown in Figures 5 and 7, the identical parts being further designated by the same references .
  • the lever 33 and the endless screw 22, modified in their shape, have been designated by the references 33 'and 22' respectively.
  • the worm 22 ' is provided with rounded notches 37 distributed around its periphery.
  • the pawl 39 is provided with a rounded head 42 engaging between two stops 43 and 44 of the lever 33 '.
  • On the head 42 rests the end of a leaf spring 45 embedded in the lever 33 'and extending in the direction of the axis 38, midway between the stops 43 and 44.
  • This spring 45 maintains the pawl-rocker 39 in one or the other of two stable positions, one of these stable positions being represented in FIG. 8. In this position one of the spouts of the pawl, in this case the spout 40 , is pressed against the worm 22 'and the spring 45 is slightly bent.
  • the stop 44 abuts against the head 42 and the pawl 39 then being locked on the lever 33', it drives the worm in the direction F3 by its beak 40.
  • the reverse movement occurs, that is to say that the head 42 again passes to the left of the spring 45.
  • the stop 43 which comes to meet the head 42 and drive the worm in the other direction F5.
  • the lever 33 ′ is stopped turning in the direction F4 as soon as a certain resistance is encountered and it returns in the direction F2, the screw is again driven in the same direction F3.
  • the invention is not limited to a shoe fitted with the rear, described by way of example, but extends to any type of shoe, the closure and tensioning device with worm screw being able to replace in particular any type of known loops.
