Definitions

  • the present application relates to alpine ski boots, in particular, so-called front-entry ski boots whose rigid shell is made up of two main parts which are, on the one hand, a lower shell and, on the other hand, a collar which can be articulated on said bottom of the shell.
  • ski boots The practice of alpine skiing on track requires particularly rigid ski boots. This is why these are made up of a rigid shell inside which a comfort inner boot is placed.
  • the invention falls within the scope of footwear of this type and sets itself the objective of improving their comfort, performance and convenience of use. To do this, the use of a cable and winder clamping device is envisaged.
  • ski touring boots are somewhat special ski boots in that they must make it possible to climb the slopes without the aid of ski lifts. To facilitate walking and climbing, they are notably much lighter and much less rigid than downhill ski boots.
  • the relative flexibility of the elements of the outer shell and in particular of the bottom of the shell have made it possible to use a cable and reel tightening device on these shoes.
  • the patent EP 3192386 describes a ski touring boot which uses a cable and winder tightening device to ensure the tightening of the bottom of the shell.
  • the patent EP 3153047 also describes a ski touring boot in which the lower portion of the shell is equipped with a cable and a winder mechanism.
  • the retractable tightening device in order to ensure that the retractable tightening device can effectively act on the relatively rigid shell, it is provided that in the area of the top of the foot, the upper opening of the bottom of the shell is framed by a panel made of a softer material. It is on this peripheral panel of the opening that the loops of the clamping device are fixed.
  • the objective of the invention is the construction of a front-entry downhill ski boot, the outer shell of which includes a bottom shell and a collar surrounding the bottom of a user's foot. Closing and tightening of the bottom of the shell are done concomitantly by moving a first portion of the bottom of the shell relative to a second portion of the bottom of the shell.
  • This shoe must combine convenience of use, precise tightening, driving performance and improved aesthetic appearance.
  • a ski boot comprising a rigid shell inside which an internal comfort liner is inserted, said shell comprising a lower shell and a collar surrounding the lower leg of a user, said collar being fixed to the bottom of the shell by means of at least two fixing means located respectively on the medial side and the lateral side of the shoe, each of the two fixing means being placed substantially at the facing the ankle joint, the shoe comprising at least one first device for tightening said shell making it possible to reduce the interior volume of the lower shell as a function of the morphology of the user's foot, and, at least , a second tightening device making it possible to reduce the inner circumference of the collar as a function of the circumference of the lower leg of the user; said first tightening device comprising a cable, a plurality of loops fixed to the bottom of the hull, and a blocking mechanism with retractor; while said second clamping device comprises an actuating member; said retractor locking mechanism of the first clamping device being placed close to the actuating means
  • the retractor blocker mechanism is placed above the fixing means which make it possible to fix the collar to the bottom of the shell.
  • the distance D separating an edge of the actuating member of the second clamping device from the adjacent edge of the retractor blocker mechanism of the first clamping device is less than 50 mm, preferably less than 30 mm.
  • the organ actuation of the second tightening device constitutes a kind of fairing, or a deflector, close to the winder. This effect is all the more interesting as the retractor is voluminous and prominent.
  • Another advantage of the proximity of the winder of the first tightening device, which ensures the tightening of the lower shell, with the second tightening device, which ensures the tightening of the collar, is that the entire area of the lower shell which envelops the foot is devoid of bulky clamping mechanisms. Indeed, only are present on this zone, the passers-by and the cable. Thus it is possible to give a better aesthetic appearance to the entire front part of the ski boot.
  • the retractor locking mechanism of the first clamping device is attached to the collar. This is the easiest construction to design within the scope of the invention.
  • the retractor blocker mechanism is fixed to the upper part of the bottom of the shell.
  • the lower part of the collar covers the upper part of the bottom of the hull, and the collar has a through opening through which projects the retractor blocker mechanism.
  • the second clamping device can be of any known type.
  • it may be of the hook-and-loop, rack and toggle mechanism type, in which case the means for actuating this second clamping device is a pivoting pallet.
  • another type of second clamping device such as a winder mechanism with cable.
  • the winder mechanism of the first tightening device is dimensioned such that it can generate a force greater than 50 daN.
  • the bottom of the shell comprises at least two portions movable relative to each other, at least one of the loops of the plurality of loops being fixed to a first of said two portions and at least one of the two loops being fixed on a second of said two portions.
  • the cable successively traverses a lacing zone, a return zone and a blocking zone; and in that the lacing zone is on the lower shell, the blocking zone is on the collar and the return zone is on the lower shell and/or on the collar.
  • the collar comprises at least two clamping means and the retractor blocker mechanism of the first clamping device is placed between said at least two clamping means.
  • one of the two tightening means is a toggle mechanism and in that one of the parts of said mechanism is inclined so as to constitute a deflector capable of protecting the roller blocker mechanism.
  • the figure 1 describes a shoe 1 provided for downhill skiing.
  • This shoe comprises an outer shell 2 inside which is inserted an inner shoe 9.
  • the inner shoe 9 is not permanently linked to the outer shell and it can be removed from the latter.
  • This is a so-called "front entry” shoe.
  • the outer shell 2 consists of two main parts: the bottom of the shell 21 and the collar 22.
  • the bottom of the shell 21 is designed to receive the foot of the user and to envelop the latter from the toes to the heel.
  • the lower shell thus covers the entire forefoot of the user up to the instep.
  • the lower shell 21 also includes two vertical extensions 211 which are on each side (lateral and medial) and are positioned at the level of the ankle joint. These vertical extensions are each pierced with an opening whose role we will see later. You can see the lateral vertical extension on the figure 1 by the dotted line 2111 which defines its outline.
  • the collar 22 is fixed to the bottom of the shell 21 at the level of the two vertical extensions 211, using at least two fixing means located respectively on the medial side and the lateral side of the shoe.
  • the fastening means can be of any type known in the field, for example rivets or screws.
  • the front upper part of the lower shell 21 defines an opening which serves, on the one hand, to facilitate the introduction of the foot and, on the other hand, to adapt the interior volume of the boot 1 to the shape of the foot of the 'user.
  • This opening is made between two portions of the lower shell which are movable relative to each other and overlap each other. In practice, these two movable portions are on the one hand, the medial flap 212, and on the other hand, the lateral flap 213.
  • the figure 2 shows in section the configuration of these two flaps 212, 213.
  • the medial flap 212 is an integral part of the lower shell 21, it constitutes the free end portion thereof on the medial side of the shoe.
  • the side flap 213 is also an integral part of the lower shell and constitutes the free end portion thereof on the lateral side.
  • the present invention is characterized by the installation of an oversized blocker on an alpine track ski boot.
  • it comprises a base 311 which is used to fix the blocker 9, a main body 312, inside which are housed the receiving reel of the cable as well as the winding and blocking mechanism and a thumb wheel. actuation 313. Because of the forces required to tighten the boot, as explained above, but also for reasons of convenience of use, this ascender is quite bulky. In practice, it has a diameter R 31 of between 30 and 55 mm and a height H 31 of between 15 and 45 mm.
  • roller blocker which is a substantially cylindrical and projecting element, is very difficult to integrate into the aesthetic appearance that the manufacturer wishes to give to his shoe.
  • the figure 1 shows all of the elements that ensure the closing and tightening of the ski boot according to the invention.
  • the lower part of the outer shell, that is to say, here, the bottom of the shell 21 is tightened by means of a first clamping device 3.
  • This first clamping device 3 comprises a winder locking mechanism 31, a cable 32 and a plurality of loops 33.
  • the winder blocking mechanism is, within the scope of this invention, a device which performs the following functions: firstly, it makes it possible to block a certain length of cable in order to guarantee the desired tightness. Then it has a store to store the length of unused cable in the lacing area. The magazine should be able to store a cable length of approximately 50mm. It is also the length of the amplitude of the clamping. Finally, it has rotary actuating means implemented by the user when he puts on the shoe and when he takes it off.
  • the retractor blocker mechanism 31 is fixed, not on the bottom of the shell 21, but on the collar 22 and the cable 32 successively traverses a lacing zone 34 and a return zone 35 before entering the retractor blocker mechanism 31 where it is tensioned.
  • the lacing zone is defined as the zone in which a pull on the cable 32 generates an effect on the lower shell 21. In other words, it is the zone for which when a pull is exerted on the cable, there is approximation of two portions of the bottom of the shell which are movable relative to each other.
  • the lacing zone 34 is characterized by the placement of the plurality of loops among which at least one of the loops, the loop 332 is fixed on the medial flap 212 and at least one other of the loops, the loop 333 is fixed on the side flap 213.
  • the retractor locking mechanism is placed above the fixing means 221, which, on the lateral side, serves to fix the collar to the bottom of the shell.
  • the figure 2 is a cross-sectional view of the boot 1 (section II-II) showing the operation of the first tightening device.
  • the medial flap 212 overlaps the side flap 213.
  • the relative movement of the medial flap 212 with respect to the side flap 213 in the tightening direction is achieved by the traction exerted by the portion of the cable 32 which passes alternately in the at least one , passing 332 of the medial flap and in the, at least one, passing 333 of the lateral flap.
  • the picture 3 is a sectional view of the collar 22 (section III-III). For reasons of simplicity, the inner boot is not shown.
  • the collar 22 When closed over the lower leg of the user, the collar 22 is intended to surround the complete circumference of the lower leg of the user. Indeed, as shown in picture 3 , the medial flank 222 of the collar covers the lateral flank 223 thereof.
  • a second tightening device 4 is fixed to the collar 22 to effect the tightening of the latter on the lower leg of the user.
  • the second clamping device 4 comprises a hook 41 with a toggle mechanism fixed to the lateral flank 223 cooperates with a rack 42 fixed to the medial flank 222.
  • the hook 41 is of the type known in the field of alpine footwear, it has a prominence P 41 of between 10 and 20 mm.
  • the prominence is defined as the maximum elevation made by the hook 41, and, to be more precise, the actuating pallet 411 of the hook 41 with respect to the outer surface of the collar 3 in the area of the latter where it is attached. This measurement of the prominence is, of course, made when the hook is in the closed position.
  • the shoe is equipped with two other tightening devices, one comprising a second hook 51, identical to the hook 41 of the second tightening device 4 and the other a tightening strap 61 arranged at the upper end of the shoe.
  • the figure 4 shows in section (section IV-IV) along a vertical plane, the portion of the collar on which are fixed the retractor blocker mechanism 31 and the two hooks 41, 51.
  • the retractor blocker mechanism 31 is placed close to the hook 41 of the second clamping device 4.
  • the second clamping device which forms a kind of fairing of the retractor blocker mechanism 31.
  • the fairing effect can be ensured both from below (hook 41) and from above (hook 51). Indeed, the retractor blocker mechanism is placed between these two hooks.
  • the gripping end of the paddle 411 makes a non-zero, and positive, angle with the vertical direction while the gripping end of the paddle 511 makes a non-zero, negative angle with the vertical direction.
  • the prominence P 41 of the hook 41 can be substantially equal to the prominence P 31 of the retractor blocker mechanism 31.
  • This is a configuration optimized which makes it possible to better integrate the mechanism of the rope clamp. Nevertheless, the desired fairing effect is present even if the prominence of the second clamping device P 41 is lower than that of the retractor blocker mechanism P 31 .
  • the prominence P 31 of the latter is equal to its height H 41 .
  • the figure 5 shows a variant of the first embodiment in which, on the one hand, the retractor blocker mechanism is fixed to the inner surface of the collar 22 and, on the other hand, a part of the blocker mechanism can be located under the collar.
  • the retractor blocker mechanism is fixed to the inner surface of the collar 22 and, on the other hand, a part of the blocker mechanism can be located under the collar.
  • the figure 6 presents a second embodiment of the invention which differs from the first embodiment by fixing the retractor blocking mechanism 31 to the outer shell of the boot.
  • the ski boot figure 6 is of the type of that of the figure 1 and for reasons of simplicity, the elements of the shoe of the first embodiment and those of the shoe of the second mode which are equivalent will keep the same reference signs in the text and the figures.
  • the bottom of the shell 21 is surmounted by the collar 22, and these two distinct elements constitute, once assembled, the outer shell of the shoe 1.
  • An opening is made on the front upper part of the lower shell 21 between the medial flap 212 and the side flap 213.
  • the medial flap 212 and the side flap 213 are integral parts of the lower shell, they are movable one by one. to each other and overlap.
