Definitions

  • the present invention relates to shoes comprising an external shell inside which a liner is inserted.
  • This type of shoe is particularly used for winter sports.
  • the outer shell is mainly rigid and provides support for the user's foot while the inner liner is more flexible and has the function of ensuring comfort for the foot.
  • FR 2661076 A1 discloses a shoe according to the preamble of claim 1.
  • Alpine ski boots in particular, include an external shell which includes a lower part and an upper part intended to wrap the lower leg area.
  • Upper part and lower part can essentially be different portions of the same structure, as in so-called rear entry shoes, but as a general rule, the upper part of the shell is a collar which is articulated on the lower part of the shell of so as to allow a certain angular movement of the leg relative to the foot.
  • the lower part has an opening on the top. This opening is closed by covering the flaps, or overlaps, which are held against each other by closing buckles.
  • two hooks are used to close the lower part of the shell, one of these hooks being located near the user's instep.
  • the instep area is a critical area for skier comfort. This is, in particular, the area where it is possible to exert an effort to keep the skier's heel firmly in place at the bottom of the boot. This is why there is systematically one of the means of tightening the shoe which is located closest, which is sometimes called the perimeter-short-heel. However, this area is located in the immediate environment of the ankle joint so that in order not to hinder movements, the position of the instep tightening hook is shifted downward. The hook in question is then placed opposite the curved area of the top of the foot.
  • this rounded area which constitutes the lower part of the instep is particularly sensitive. This is why these skiers may need to turn to ski boot fitting professionals, commonly called “bootfitter”.
  • Bootfitters can intervene in multiple ways on a ski boot to conform it as closely as possible to the particularities of a user's foot. In particular, they can deform the hull, "grind” it in all areas where this is possible. However, it is sometimes difficult to intervene at the instep due to the presence of the instep tightening hook. On the other hand, the modifications to the shell that the bootfitter makes in this area may simply have no effect on comfort, as soon as the user tightens the shoe.
  • the objective of the invention is to provide a sports shoe having an outer shell and an inner liner which does not have the disadvantages of the prior art.
  • the objective of the invention is therefore to provide a sports shoe, in particular an alpine ski shoe, which improves the support of the foot and in particular the support of the ankle while guaranteeing better comfort compared to shoes of the prior art.
  • the objective of the invention is also to facilitate the work of bootfitters when they modify a stock shoe in order to conform it to a user's feet.
  • the objective of the invention is achieved by providing a shoe according to claim 1.
  • the shoe is an alpine ski boot which comprises an outer upper and an inner liner.
  • the outer rod has two flanks (a medial flank, a lateral flank) whose upper ends, namely the lateral flap, respectively, the lateral flap, are movable relative to each other and are overlap to tighten the shoe.
  • connection means interconnect the internal traction means and the external traction means.
  • said tightening means are placed at the level of the upper part of the instep, close to the short heel perimeter line.
  • said actuation means is fixed on the lateral side of the lower part by a first external anchoring, and the external traction means are fixed on the medial side of the lower part by a second external anchoring while the internal traction means are fixed to the external rod by an internal anchoring.
  • FIG. 1 shows in side view, the side face of an alpine ski boot.
  • the internal comfort element is in the form a liner completely independent of the outer upper and which can therefore be extracted from the outer upper for replacement, drying or even to make modifications to it.
  • the present invention is described below for shoes having a removable internal comfort element, this characteristic does not constitute a limitation.
  • the outer rod 1 is in the form of a relatively rigid shell made by injection of a thermoplastic material such as PU (polyurethane), PA (polyamide), PP (polypropylene) or any other equivalent material or any combination of the aforementioned materials. It is of course possible to make the outer upper in a different way, for example by assembling several textile panels and/or plastics or by stiffening fiber plies (carbon, glass, base, linen, etc.) within a thermosetting or thermoplastic resin matrix.
  • PU polyurethane
  • PA polyamide
  • PP polypropylene
  • the outer upper 1 mainly consists of a lower part 11, designed to accommodate the user's foot and an upper part 12 designed to surround the lower leg.
  • the upper part 12 is fixed on the lower part 11 with a slight possibility of movement so as to accompany the flexion generated by the ankle joint.
  • the lower part 11 consists of a sole 113 from which comes a heel counter 114, a forefoot box 115 as well as the medial sidewall 111 and the lateral sidewall 112 which connect the forefoot box 115 and the heel counter 114 on the medial side, respectively the lateral side of the shoe.
  • the upper end of the medial sidewall 111 as well as that of the lateral sidewall 112 are substantially movable relative to each other and to the rest of the outer rod.
  • the upper ends of the sides constitute flaps, also called “overlaps” which overlap to close the upper opening 116 and ensure its sealing.
  • the medial flap 1111 covers the lateral flap 1121.
  • the outer upper of the shoe shown in figure 1 comprises five tightening means, two of them ensure the tightening of the lower part 11 and the other three are dedicated to the upper part 12 of the outer rod.
  • the means for tightening the upper part 12 include two rack buckles 33, 34, the use of which is very common in the field of alpine ski boots.
  • the upper part consists of an open collar whose two free ends overlap. One of the ends carries a loop with a toggle mechanism and the other end carries a rack 328 comprising a plurality of teeth.
  • a toggle mechanism buckle is shown in top view at figure 13 .
  • the loop 32 is fixed on the outer rod via a yoke 324.
  • a pallet 323 for actuating the clamping means is pivotally mounted on the yoke 324 thanks to the two axes 326.
  • the loop 321 strictly speaking , is connected to the pallet 323 using a tie rod 322, which is pivotally mounted thanks to the axis 325 in a notch provided in the center of the pallet 323.
  • a pin 327 placed at the distal end of the loop 321 is designed to cooperate with the teeth of the rack 328, the cooperation of the pin with one or the other of the teeth ensuring a different adjustment of the tightening means.
  • Clamping means 33 and 34 are therefore clamping means of the type just described.
  • the upper tightening means 35 commonly called lower leg tightening, is of a different type. This is a means of tightening which offers more flexibility and a greater range of adjustment.
  • the means for tightening the lower part 11 of the outer rod comprise a rack buckle 32 similar to that described above and a strap tightening means notched and ratchet 31, commonly called “ratchet”.
  • the rack buckle 32 ensures the tightening of the forefoot part of the lower part of the upper while the tightening means with notched strap and ratchet 31 ensures the tightening at the level of the upper part of the instep .
  • THE figures 14 and 15 respectively show a top view and a side view of such a ratchet tightening means.
  • the clamping means is anchored on one of the portions of the outer rod via a yoke 314.
  • An actuation pallet 313 is rotatably mounted on the yoke thanks to the two axes 316.
  • a tunnel 317 is pivotally mounted at the inside a notch made in the pallet 313 via an axis 315 which is offset relative to the axes 316.
  • the tunnel 317 receives the notched strap 312 which is able to slide there in both directions.
  • a ratchet 318 equipped with a tooth designed to cooperate with the teeth of the notched strap is pivotally mounted. The rotation of the ratchet is constrained by a spring in such a way that, in the rest position, the tooth of the ratchet prevents sliding in the direction of loosening the notched strap. The tightening action is carried out in two successive phases.
  • the pivoting of the pallet 313, which carries with it the tunnel 317 in a forward translation movement results in the sliding of the notched strap in the tightening direction.
  • the pivoting of the pallet 313 in the other direction brings the tunnel towards the rear as well as the notched strap, the sliding of which in the tunnel is prevented by the ratchet.
  • the tightening action of the notched strap tightening means is carried out closest to the shortest line connecting the medial support of the user's heel to the lateral support of the same heel and passing over the foot .
  • the proximity of the tightening plane to the plane defined by this line called the “short heel perimeter” line, ensures optimal positioning of the foot in the shoe because, thus, the foot is well wedged against the rear of the shoe.
  • the upward movement of the instep tightening frees up a little the area located directly below and which in the shoes of the prior art is occupied by a ratchet buckle type tightening means.
  • a bootfitter may be possible for a bootfitter to modify this area of the shell to adapt it to the shape of a specific user's foot.
  • Plane II-II corresponds substantially to the plane traversed by the short heel perimeter line, as defined above.
  • this comprises a sole 113 from which the medial sidewall 111 and the lateral sidewall 112 come.
  • the lower part being produced by injection of thermoplastic material, the sole as well as the two sidewalls constitute a same piece in one piece.
  • This last characteristic does not constitute the only possibility of manufacturing the outer rod. Indeed, we could consider producing this by an assembly of different parts made integral and immobile in relation to each other by any suitable means of fixing.
  • the medial flap 1111 overlaps the lateral flap 1121.
  • the flaps are sufficiently mobile relative to each other to allow, on the one hand, to move away from one another. on the other hand, thus enlarging the upper opening 116 and on the other hand, to slide one over the other, thus reducing the interior volume of the shoe.
  • the clamping device characteristic of the invention presents an actuation means 30.
  • the actuation means is represented schematically by a first functional box in dotted lines and referenced with the sign 30 because, as will be seen later, this actuation means can take several forms without departing from the scope of the invention. It may in particular consist of a pallet of the ratchet and notched strap tightening mechanism 31 described in figures 1 , 14 and 15 , or else in a pallet of the loop and rack mechanism 32 as described in figure 13 .
  • the actuation means 30 is fixed, or can be removably fixed, to the lateral side 112 of the outer rod thanks to a first external anchoring 301. It is functionally connected to the medial side 111 via external traction means 50 so as to ensure the tightening of the rod.
  • the external traction means 50 are fixed, or alternatively, can be removably fixed, to the lateral side 111 of the external rod via a second external anchoring 502.
  • the tightening device of the invention further comprises internal traction means 60 which are essentially placed under the outer rod and fixed thereto thanks to an internal anchoring 603.
  • the external traction means 50 and the internal traction means 60 are associated in such a way that the actuating means 30 acts simultaneously on the internal and external traction means.
  • the connection means which ensure this function are represented by a second functional box in dotted lines and referenced with the sign 40.
  • THE figures 3, 4 And 5 schematically illustrate three possible configurations for producing the connection means 40 between internal traction means 60 and external traction means 50.
  • the connection is fixed, so that when the actuation means 30 exert a force on the connection means, this will be distributed on the internal traction means 60 or external 50 depending on a certain number of factors.
  • the internal and external traction means have an identical Young's modulus, this is the relationship between, on the one hand, the distances separating the second anchor 502, respectively the third anchor 603, the connection means and, d
  • the length of the internal and external traction means which will determine how this distribution will take place.
  • connection is adjustable and it is possible to adjust the relative length of the internal traction means and the external traction means. It is then possible to choose a distribution of the force exerted by the actuation means 30 on the internal and external traction means. We can choose different alternatives for adjusting the connection means. It is for example possible to allow the length adjustment of the internal traction means and/or the external traction means.
  • connection between the internal traction means 60 and the external traction means 50 is free so that force balancing occurs automatically.
  • the internal traction means and the external traction means are placed in continuity with each other, which can for example be made up of the same strap, and they pass through a loop 41 which is connected to the means of actuation and which, thus, constitutes the means of connection.
  • the operation of the complete clamping device is generally the same.
  • the external traction means placed in tension thanks to the actuation means ensure the tightening of the external rod in a conventional manner. That is to say that the medial sidewall 111 approaches the lateral sidewall 112.
  • the internal traction means 60 which are placed under the outer rod act on the internal comfort element 2, it -even placed inside the stem. They allow, in fact, to tighten the internal comfort element against the user's foot.
  • the internal anchoring means 601 is positioned as low as possible inside the outer rod. In the first embodiment, the internal anchor 601 is placed at the level of the sole 113. It is therefore placed below the internal comfort element.
  • the internal 50 and external 60 traction means can be produced in many different ways.
  • the internal traction means are flat and relatively flexible. It is necessary, in fact, to avoid that they constitute too great an excess thickness. They can, for example, consist of a textile strap, a cable or a thermoplastic strip. In advantageous embodiments, they are made of an elastic material, or have an elastic portion.
  • the external traction means can, of course, be of the same nature as the internal traction means, that is to say strap, elastic or not, cable, etc. But they can also consist of a loop of means classic tightening like the loop 321 shown in Figure 13 .
  • the tightening means according to the invention can make it possible to save a little weight because common actuation means simultaneously ensure the internal tightening of the comfort element and the external tightening of the outer rod, but also to improve the effectiveness of external tightening.
  • the external tightening of the external rod is all the easier since the tightening of the internal comfort element does not have to be carried out transitively by the external traction means but by distinct internal traction means of these.
  • one of the major advantages of the tightening means according to the invention is to improve the hold of the ankle by carrying out internal tightening of the latter. This is particularly the case when the internal traction means have a certain elasticity.
  • FIG. 6 represents in section along plane II-II, the lower part of the outer rod according to a second embodiment of the invention.
  • the internal traction means 60 comprise a portion medial portion 61 and a lateral portion 62.
  • the medial portion 61 is placed under the medial sidewall 111 and is fixed inside the outer rod via a first internal anchoring 611, while the lateral portion 62 is placed under the sidewall 112 and is fixed inside the latter by a second external anchoring 621.
  • connection means 70 placed above the internal comfort element 2, near the upper opening 116 of the outer rod.
  • connection means 70 can take several configurations.
  • connection means 70 schematically represent different configurations that the connection means 70 can take.
  • Figure 7 the medial portion 61 and the lateral portion 62 are secured to each other in a fixed manner.
  • the connection means 70 are fixed. They can be detached to facilitate the installation of the foot or the extraction of the internal comfort element 2 from the external upper, but when they are in place, there is no movement between lateral portion and portion medial.
  • the connecting means are free, the lateral portion 62 ending in a loop through which the medial portion 61 passes.
  • the connecting means are also free, but it is the medial portion 61 which ends in a loop through which the lateral portion 62 passes.
  • connection means 60 can take one of the configurations described above in the figures 7, 8 And 9 .
  • FIG 11 represents a second variant of the second embodiment of the invention in which for reasons of simplicity of construction, the internal traction means 60 do not have an attachment point on the inside of the rod. These are placed around the entire inner periphery of the outer rod. Of course, the internal comfort element 2 which is not shown in this figure is placed inside the internal traction means 60 and therefore ensures the anchoring of the latter.
  • FIG. 12 represents the lower part of the outer upper of the shoe equipped with a tightening means according to a third embodiment of the invention.
  • This tightening means is characterized by the fact that it ensures both the tightening of the shoe at the level of the instep like the different embodiments described above but also the tightening of the forefoot area .
  • the actuation means 30 is constituted by a cable reel fixed on the lateral side 112 by a first external anchor 301 and by a cable fixed on the medial side 111 by a second external anchor 302.

  • the internal traction means and the external traction means are made with different materials, but they are secured to each other by sewing, gluing or any equivalent means.
  • connection means 40 are of the same nature as those described in figure 8 . This is a loop through which, on the one hand, the traction means 50, 60 pass and, on the other hand, the cable 38.
  • the cable 38 also passes through loops 303 placed on either side. and other of the upper opening.
  • the rotation of the wheel of the actuating means 30 exerts traction on the cable 38, which subsequently exerts traction, not only on the connection means 40 and the internal and external traction means associated with it, but also , on the medial 111 and lateral 112 sides thanks to the loops 303 and the anchoring 302.
