Description

La présente invention concerne une chaussure pour sport de glisse, en particulier ski alpin, dont la tige est constituée, d'une part, d'une coque en matière plastique à volume variable se fermant sur le dessus du pied et le cou-de-pied par deux rabats superposés et munie d'au moins un dispositif de fermeture et de serrage comprenant une partie solidaire du côté de la coque correspondant au côté interne du pied et une partie solidaire du côté opposé, externe, de la coque, la coque présentant des zones de rigidités sensiblement différentes et, d'autre part, d'une manchette articulée sur la coque en deux points opposés dans la région malléolaire, s'ouvrant vers l'avant, munie d'au moins un dispositif de fermeture et de serrage et présentant également des zones de rigidités sensiblement différentes.The present invention relates to a shoe for sport of slips, in particular downhill skiing, whose stem is consisting, on the one hand, of a shell made of variable volume plastic closing on top of the foot and the instep by two overlapping flaps and provided with at least one closure device and clamping comprising an integral part on the side of the shell corresponding to the inner side of the foot and a integral part of the opposite, external side of the hull, the shell having areas of rigidities substantially different and, on the other hand, an articulated cuff on the hull in two opposite points in the area malleolar, opening towards the front, provided with at least a closing and clamping device and presenting also areas of rigidities substantially different.

Dans les chaussures à coque rigide selon l'art antérieur, lors de la flexion de la jambe, la boucle inférieure de la manchette vient s'appuyer sur la coque qui contrôle ainsi la flexion de la chaussure.In hard-shell shoes according to art anterior, during flexion of the leg, the loop bottom of the cuff comes to rest on the hull which controls the bending of the shoe.

Dans le brevet FR 2 077 184, il est proposé de réaliser des chaussures de ski ayant des caractéristiques aussi voisines que possible des chaussures en cuir en utilisant deux ou plusieurs matières plastiques ayant des propriétés mécaniques différentes. La coque de la chaussure est formée par injection successive de matière plastique avec introduction d'éléments de renfort dans des points déterminés de la matière injectée. La coque obtenue est ainsi une coque relativement souple munie de zones de renfort pour l'ancrage des boucles de la chaussure.In patent FR 2 077 184, it is proposed to carry out ski boots with characteristics also as close as possible to leather shoes in using two or more plastics having different mechanical properties. The hull of the shoe is formed by successive injection of plastic material with introduction of elements of reinforcement in specific points of the material injected. The hull obtained is thus a hull relatively flexible with reinforcing zones for anchoring the loops of the shoe.

De la demande de brevet EP 0 645 101 on connaít en outre une coque de chaussure de ski présentant des zones de rigidités et de résistances différentes, les parties les plus résistantes et les plus rigides constituant une sorte d'armature triangulée dont le rôle est une transmission optimale des efforts entre la jambe et la fixation.From the patent application EP 0 645 101, it is known in in addition to a ski boot shell with areas of different rigidities and resistance, most resistant and rigid parts constituting a kind of triangulated armature whose role is an optimal transmission of efforts between the leg and fixation.

Ces constructions ont pour but d'alléger la chaussure sans affaiblir l'ancrage des boucles et en conservant à la chaussure une rigidité suffisante pour jouer son rôle d'interface entre le pied et le ski.These constructions are intended to lighten the shoe without weakening the anchoring of the loops and keeping in the shoe a sufficient rigidity to play his role of interface between the foot and the ski.

Si on ne considère que la coque et la manchette, les limites de l'allégement semblent avoir été atteintes, si l'on désire que la chaussure conserve des caractéristiques de flexion et d'appui arrière suffisantes.If we consider only the shell and the cuff, the limits of relief seem to have been reached, if it is desired that the shoe retain bending and backing characteristics sufficient.

L'invention a pour but d'aller au-delà de ces limites en prenant en considération l'ensemble de la chaussure, c'est-à-dire la coque et sa manchette généralement dénommée collier.The invention aims to go beyond these limits taking into consideration the whole of the shoe, that is, the shell and its cuff usually called necklace.

La chaussure selon l'invention est caractérisée, en ce que les côtés de la coque présentent des zones de moindre rigidité laissant subsister, sur les deux côtés de la coque, une zone de talon rigide se prolongeant vers l'avant par une bande latérale oblique s'étendant au moins jusqu'au dispositif de serrage situé le plus en avant de manière à porter ce dispositif de serrage, et en ce que la manchette présente une zone de plus grande rigidité comprenant deux joues latérales, par lesquelles la manchette est articulée sur lesdites bandes latérales de la coque, et au moins un collier relié auxdites joues et portant le dispositif de fermeture et de serrage, et en ce que l'arrière de ce collier est relié à la zone de talon de la coque par un organe de liaison résistant à la traction et/ou à la compression, de telle sorte que ladite bande oblique, le collier et ledit organe de liaison forment une ossature assurant à elle seule la cinématique de la chaussure.The shoe according to the invention is characterized, in that the sides of the hull have zones of less stiffness, leaving on both sides of the hull, a rigid heel area extending forward by an oblique sideband extending at least to the nearest clamping device forward so as to carry this clamping device, and that the cuff has one more area high rigidity comprising two lateral cheeks, for which the sleeve is hinged to said sidebands of the hull, and at least one collar connected to said cheeks and carrying the device closing and tightening, and in that the back of this collar is connected to the heel area of the hull by a binding member resistant to traction and / or compression, so that said oblique band, the collar and said connecting member form a framework alone ensuring the kinematics of the shoe.

Par cinématique on entend, en particulier, le contrôle de la flexion de la chaussure.Kinematics means, in particular, the control bending of the shoe.

L'ossature remplit à elle seule toutes les conditions mécaniques nécessaires à la pratique du ski et elle peut être réduite au minimum, l'étanchéité étant assurée par la partie de moindre rigidité dont l'épaisseur peut être réduite puisque cette partie n'a plus de fonction mécanique. Le poids de la chaussure s'en trouve par conséquent encore réduit.The frame alone fulfills all the conditions necessary for the practice of skiing and she can be reduced to a minimum, the watertightness being ensured by the part of less rigidity the thickness can be reduced since this part has more mechanical function. The weight of the shoe consequently, it is further reduced.

En d'autres termes, contrairement aux chaussures traditionnelles qui forment un tout et réagissent globalement, la chaussure selon l'invention a été totalement restructurée afin que chaque partie joue un rôle bien précis : la partie de moindre rigidité, souple, assure l'étanchéité, la partie rigide constitue une ossature et l'organe de liaison régule la flexion et l'appui arrière.In other words, unlike shoes traditional forms that form a whole and react overall, the shoe according to the invention has been totally restructured so that each party plays a precise role: the part of less rigidity, flexible, ensures tightness, the rigid part constitutes a framework and the connecting body regulates flexion and the back support.

L'organe de liaison entre le collier et la coque peut être une barre rigide ou une liaison élastique en traction permettant une flexion de la manchette vers l'avant de manière à accompagner la flexion de la jambe ou encore une liaison élastique en traction et en compression de manière à amortir également les chocs vers l'arrière.The connecting member between the collar and the shell can be a rigid bar or an elastic connection in traction allowing a flexion of the cuff towards the front so as to accompany the flexion of the leg or else an elastic connection in tension and in compression so as to also dampen shocks rearward.

L'organe de liaison peut être également constitué d'un dispositif à déclenchement de type genouillère tel que décrit dans la demande de brevet WO PCT/US 20203 destiné à la protection du ligament croisé antérieur.The liaison body may also consist of a knee-type trigger device such as described in patent application WO PCT / US 20203 intended for the protection of the anterior cruciate ligament.

La coque et le collier seront avantageusement réalisés par un procédé de bi-injection consistant à injecter successivement dans le même moule ou dans deux moules successifs des matières plastiques de rigidités différentes.The shell and the collar will be advantageously made by a bi-injection method of injecting successively in the same mold or in two molds successive plastics rigidities different.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution d'une chaussure de ski selon l'invention.The attached drawing represents, as an example, a execution of a ski boot according to the invention.

La figure 1 représente une vue latérale de la chaussure, vue du côté externe du pied.Figure 1 shows a side view of the shoe, seen from the external side of the foot.

La figure 2 représente la même chaussure vue du côté interne du pied. Figure 2 shows the same shoe seen from the side internal foot.

La chaussure de ski représentée est constituée d'une coque 1 à volume variable et d'une manchette 2 articulée sur la coque 1 en deux points opposés 3 et 4 situés dans la région malléolaire. La coque 1 est munie de deux boucles 11 et 12 et la manchette 2 de deux boucles 22 et 23.The ski boot represented consists of a hull 1 with variable volume and a cuff 2 articulated on the hull 1 in two opposite points 3 and 4 located in the malleolar area. The hull 1 is provided of two loops 11 and 12 and the cuff 2 of two loops 22 and 23.

La coque 1 à volume variable est constituée de deux matières plastiques de rigidités différentes. Les zones de plus grande rigidité sont tout d'abord la zone de talon 5 et la zone de semelle avant 6. La zone de talon 5 présente un trottoir arrière 7 destiné à l'appui d'un élément de fixation arrière, tandis que la zone de semelle avant 6 présente un trottoir avant 8 destiné à recevoir l'appui d'une fixation avant et une partie verticale 9 également destinée à recevoir l'appui frontal des mâchoires d'une fixation avant. La zone de talon est prolongée, du côté externe de la coque, par une bande 10 s'étendant obliquement vers l'avant jusqu'à la boucle 11 située le plus en avant de la coque de telle manière que l'embase du levier-tendeur de cette boucle 11 est fixée sur la zone 10 de plus grande rigidité. La bande 10 pourrait s'étendre plus loin de manière à venir sur le bout du pied. L'embase du levier-tendeur de la boucle 12 est bien entendu également fixée dans la zone 10.The hull 1 with variable volume consists of two plastics of different rigidities. Areas of greater rigidity are first of all the zone of heel 5 and the front sole area 6. The heel area 5 has a rear sidewalk 7 intended to support a rear fastening element, while the zone of front sole 6 has a front sidewalk 8 for receive the support of a binding before and a part vertical 9 also intended to receive support front of the jaws of a front fixation. The zone of heel is extended on the outer side of the shell by a band 10 extending obliquely forwards until the loop 11 located the most forward of the shell in such a way that the lever-lever base of this loop 11 is fixed on the zone 10 more high rigidity. Band 10 could expand more far to come on the tip of the foot. The base of the lever-tensioner of the buckle 12 is of course also fixed in zone 10.

Du côté interne de la coque, la zone de talon 5 est également prolongée par une bande 13 de plus grande rigidité s'étendant également obliquement vers l'avant sur une distance telle que les crémaillères d'accrochage des boucles 11 et 12 sont fixées sur cette bande 13.On the inner side of the hull, the heel zone 5 is also extended by a band 13 of larger rigidity also extending obliquely forward over a distance such as the racks hooking loops 11 and 12 are fixed on this band 13.

Le reste de la coque, c'est-à-dire les zones métatarsophalangiennes 14 et 15 s'étendant de chaque côté de la coque, de l'avant jusque sous la plante du pied, en dessous des bandes 10 et 13, les rabats 16 et 17 et la zone postérieure 18 s'étendant au-dessus du talon, autour du tendon d'Achille sont constitués d'un plastique présentant une moindre rigidité.The rest of the hull, that is, the metatarsophalangeal areas 14 and 15 extending on either side of the hull, from the front to under the sole of the foot, below the strips 10 and 13, the flaps 16 and 17 and the posterior zone 18 extending above the heel, around the Achilles tendon are made up of a plastic with less rigidity.

La manchette 2 est également constituée de deux matériaux de rigidités différentes. La zone la plus rigide forme deux joues latérales 19 et 19a par lesquelles la manchette 2 est articulée en 3 et 4 sur des excroissances latérales 10a et 13a des bandes 10 et 13 de la coque 1 et deux colliers 20 et 21 situés l'un au-dessus de l'autre. Le collier 20 porte la première boucle 22 et le collier 21 la seconde boucle 23, boucles qui permettent la fermeture et le serrage des colliers et par conséquent de la manchette 2 autour de la jambe.The cuff 2 also consists of two materials of different rigidities. The most rigid form two side cheeks 19 and 19a by which the sleeve 2 is articulated in 3 and 4 on lateral protuberances 10a and 13a of the strips 10 and 13 of the shell 1 and two collars 20 and 21 located one on top of each other. Necklace 20 is the first loop 22 and the collar 21 the second loop 23, loops that allow the closing and tightening of collars and hence the 2 cuff around leg.

Les colliers 20 et 21 sont reliés à la coque 1 par un organe de liaison 24, dont l'extrémité inférieure est articulée en un point 25 sur un prolongement 26 de la zone de talon 5 de la coque vers le haut. Dans l'exemple d'exécution représenté, l'organe de liaison 24 est un organe présentant une élasticité en compression et en traction, mais présentant une résistance limitée à la compression et déclenchant vers l'arrière lors d'une surcharge, tel que décrit dans la demande de brevet WO PCT/US 20203.The collars 20 and 21 are connected to the shell 1 by a connecting member 24, whose lower end is articulated at a point 25 on an extension 26 of the heel area 5 of the hull up. In the illustrated embodiment, the connecting member 24 is a member having elasticity in compression and traction, but presenting a limited resistance to compression and triggering towards the rear during an overload, as described in the patent application WO PCT / US 20203.

Le reste de la manchette 2, en particulier les zones 27 et 28 situées respectivement au-dessus et au-dessous du collier 20, est en matière plastique présentant une moindre rigidité.The rest of the cuff 2, especially the areas 27 and 28 respectively above and below the collar 20, is made of plastic material having a less rigidity.

Sur le dessin, on distingue en outre une courroie 29 fixée au dos de la partie supérieure de la manchette 2, à l'intérieur de celle-ci, par des rivets 30 et servant, de manière connue, d'appui tibial à un chausson de confort 31.In the drawing, there is furthermore a belt 29 attached to the back of the upper part of the cuff 2, inside of it, by rivets 30 and serving, in known manner, tibial support to a comfort slipper 31.

De chaque côté de la chaussure, la bande 10, respectivement 13, les colliers 20 et 21 et l'organe de liaison 24 forment ainsi un système triangulé dont la rigidité assure un bon guidage du ski et un parfait ancrage des boucles. La surface des zones rigides est minimale.On each side of the shoe, the band 10, respectively 13, the collars 20 and 21 and the connection 24 thus form a triangulated system whose stiffness ensures good skiing guidance and a perfect anchoring loops. The surface of the rigid areas is minimal.

En ce qui concerne l'organe de liaison 24, il pourrait être constitué d'une simple barre rigide ou d'une liaison comprenant un ressort travaillant en traction ou en traction et en compression.As regards liaison body 24, it could consist of a simple rigid bar or a linkage comprising a spring working in tension or in tension and compression.

Les zones de moindre rigidité pourraient être constituées d'un tissu imperméable, en particulier un tissu microporeux.Areas of less rigidity could be consisting of an impermeable fabric, in particular a microporous tissue.

La structure selon l'invention est applicable à toute chaussure pour sport de glisse, tel que ski et surf.The structure according to the invention is applicable to any sports shoe for gliding, such as skiing and surfing.
