Definitions

  • the present invention relates to a plastic ski boot comprising a variable volume shell surrounding the foot and the heel and having two longitudinal flaps overlapping on at least part of the foot but only one of which extends simultaneously and above the instep, that is to say at the level of the lower leg, an auxiliary attached piece cooperating with said single flap to cover the instep, a rod in the form of a collar attached to the shell and means for clamping the shell and the collar.
  • a shoe of this type in which the added auxiliary piece consists of a flap fixed laterally to the shell at one or two points and coming, on the one hand, covering the instep with the flap of the shell extending above the instep and, on the other hand, covering the transverse edge of the interrupted flap of the shell.
  • the purpose of this construction is to ensure optimal fixation of the foot inside the boot and at the same time optimal adaptation to the skier's foot. It was not taken into account that all the supports on the ski are made by the interior side of the boot, because in this construction the internal support takes place on an insert therefore not very rigid and the transmission of forces to skiing is not optimal.
  • the tightening of the foot is done by means of a loop acting on the auxiliary part, that is to say near the instep.
  • a loop acting on the auxiliary part that is to say near the instep.
  • by tightening the foot with a fourth loop there is a strong risk of create a space between the shell and the auxiliary part in the case where the clamping on the auxiliary part is weaker than on the forefoot, which is often the case, because, near the instep, it is advisable to leave some clearance in the tendon of the foot to expand.
  • the game created has the effect of removing the waterproofness of the shoe, hence, ultimately, the need to give up the fourth loop.
  • a shoe is also known whose shell has two slots extending parallel to each side of the foot and defining a tongue covering the foot and the instep, this tongue being partially covered by a split sleeve surrounding the shell and covering the slots.
  • the extended tongue makes it easier to put on, but the slots greatly reduce the rigidity of the shell on each side of it and hence its ability to transmit forces to the ski.
  • a plastic shoe is also known, the shell of which has an opening disposed along the instep intended to allow the introduction of the foot into the shell, this opening being covered by a tongue articulated on the front of the hull.
  • this construction cannot be used with a collar-shaped rod, but with a two-part rod in the form of a gutter.
  • the object of the present invention is to produce a shoe with a variable volume shell and a collar-shaped upper, the boot of which is facilitated without risk of loss of tightness and ensuring optimum transmission of the forces from the leg to the ski.
  • the shoe according to the invention is characterized in that the flap of the shell extending to above the instep is the flap on the inside of the shoe and that said added auxiliary part is secured to a covering piece of the metatarsophalangeal zone.
  • the covering part can be either enveloping, in the form of a band surrounding the shell over a little more than 360 ° in the closed and tight position, or in the form of a hood maintained by clamping cables.
  • the auxiliary part may have come from an injection part with the covering part or else added, for example by ultrasonic welding or overmolding.
  • the auxiliary part can advantageously have a resistance and a hardness different from the covering part.
  • the covering part can thus be made of relatively rigid material, for example in polyurethane loaded with KEVLAR (registered trademark), while the auxiliary part is made of a more flexible material to facilitate fitting. Such a structure can also be obtained by the bi-injection technique.
  • Figure 1 is an exploded perspective view of the component parts of the shell of the shoe according to a first embodiment.
  • Figure 2 is a perspective view of the shell after assembly.
  • FIG. 3 represents an alternative embodiment of FIG. 2.
  • Figure 4 is an exploded view of a shell with its rod made according to the first embodiment.
  • FIG. 5 represents a complete shoe produced according to FIG. 4.
  • Figure 6 shows a second embodiment of a complete shoe without the buckles and tensioner lever.
  • Figure 7 is an exploded view, similar to Figure 1, of a third embodiment.
  • Figure 8 is a similar view of a fourth embodiment.
  • Figure 9 is a detail of Figure 8.
  • FIG. 1 represents a shell 1, for example made of polyurethane, comprising the sole and surrounding the foot and the heel.
  • This shell is of variable volume, that is to say that it can open along a longitudinal line on the foot, this opening being obtained by two flaps 2 and 3.
  • the flap 2 stops a little above the malleolus, while the flap 3 extends over and above the instep by a part 3a which partially envelops the inner side of the ankle.
  • the shell 1 is provided with a tongue 4 which covers the Achilles tendon.
  • the shell is completed by a covering part 5 in the form of a collar, the outer side of this collar being extended by an auxiliary part 6 of curved shape and extending upwards and backwards and of roughly symmetrical shape. to that of part 3a.
  • the cover 5 surrounds the shell 1 in the metatarsophalangeal region, its ends forming two flaps 5a and 5b which are superimposed in the same way as the flaps 2 and 3 of the shell.
  • the auxiliary part 6 covers the part left free by the flap 2 above the malleolus, thus replacing the missing part of the flap 2.
  • the auxiliary part 6 is connected to the covering part 5 by a relatively narrow part facilitating bending from Part 6 in this area.
  • the auxiliary part 6 thus deviates easily, facilitating the introduction of the foot into the shell.
  • the tightening of the metatarsal part of the hull is done by the tightening of the covering part 5, in the same way as the tightening of a conventional hull with variable volume.
  • the tightening loops are fixed on the covering part 5, so that it is not necessary to make any hole in the shell itself, and that the latter consequently has advantageous continuity and greater resistance. .
  • the hull can also be lightened.
  • the shell 1 and the covering part 5 can also be assembled as shown in FIG. 3.
  • the flap 5b of the covering part 5 is taken between the lower flap 2 and the upper flap 3 of the shell and the auxiliary part 6 comes inside the hull, under part 3a.
  • the shoe uses the embodiment according to FIG. 2.
  • the shell is completed by a collar 7 articulated on the shell 1 and forming the upper of the shoe.
  • This collar 7 is scalloped at the rear, the scallop being closed by a cover 8 also articulated on the shell.
  • This construction is described in US patents 4,839,973 and EP 0 286 586.
  • Figure 5 shows the same complete shoe.
  • the cover 8 is articulated at 10 on the hull.
  • the metatarsal part of the foot is tightened by means of two loops 11 and 12 fixed on the outside of the covering part 5 and making it possible to exert traction on two cables 13 and 14 anchored in the flap 5a or more behind that -this.
  • the collar 7 is closed and tightened in a known manner by means of two loops 15 and 16.
  • FIG. 6 represents another embodiment in which the covering part is in the form of a cover 20.
  • cables such as cables 21 and 22, themselves connected to tensioning devices for tightening the forefoot and instep.
  • the cables can also be used to retain the cover 20.
  • the cable 21 can form a loop on the other side of the cover 20.
  • the cable 22 is anchored to the cover 20 at a point 23 and it passes below the rivet.
  • articulation 10 of the stirrup 8 to come out substantially vertically on the collar 7 by a passage 24 where it is attached to a not shown tensioning lever fixed on the collar.
  • a third embodiment is shown in Figure 7. This embodiment differs from the first embodiment in that the shell 1 has a cutout 25 on the foot leaving only primers for flaps 2 and 3 except on the instep at 26 and at their front ends at 27 where they overlap as in the first embodiment.
  • the cutout 25 is covered by the covering part 5.
  • a fourth embodiment is shown in Figures 8 and 9. This differs from the third embodiment in that the shell 1 has a cut 28 similar to the cut 25, but wider and extending up to 'at the front end of the flaps 2 and 3 so that these flaps are removed except at 26 on the instep.
  • the covering part 5 covers the front of the cutout 28, the seal being ensured by a seal gasket 29 bonded to a surface 30 of the shell slightly set back from the surface of the shell.
