Description

La présente invention concerne une chaussure de sport, adaptée notamment pour la pratique du ski, de l'alpinisme et de la marche.The present invention relates to a sports shoe, suitable in particular for skiing, mountaineering and walking.

Pour assurer la sécurité de l'utilisateur et garantir un confort optimal lors de la pratique du ski, les chaussures de ski ont généralement une coque rigide dans laquelle est inséré un chausson intérieur souple. La coque comprend généralement plusieurs éléments constitués d'une matière plastique composite relativement rigide, et le chausson est confectionné en assemblant plusieurs panneaux de mousse ou de tissu.To ensure the safety of the user and ensure optimum comfort when skiing, ski boots generally have a rigid shell in which is inserted a soft inner boot. The shell generally comprises a plurality of elements made of a relatively rigid composite plastic material, and the liner is made by assembling several panels of foam or fabric.

EP-A-0 406 212 divulgue une chaussure de ski alpin comprenant une partie basse prévue pour envelopper le pied de l'utilisateur, et une partie haute, ou collier, prévue pour entourer le bas de la jambe. Le collier est articulé en rotation avec la partie basse autour d'un axe correspondant à l'axe d'articulation de la cheville de l'utilisateur. La rotation du collier vers l'arrière est verrouillée de manière à permettre l'appui des jambes du skieur vers l'arrière, lors de la pratique du ski. La chaussure autorise une légère rotation du collier vers l'avant afin de permettre à l'utilisateur de se pencher vers l'avant. EP-A-0 406 212 discloses an alpine ski boot comprising a lower part intended to wrap the foot of the user, and an upper part, or collar, intended to surround the bottom of the leg. The collar is articulated in rotation with the lower part about an axis corresponding to the axis of articulation of the user's ankle. The rotation of the collar towards the rear is locked so as to allow the support of the skier's legs towards the rear, during the practice of skiing. The shoe allows a slight rotation of the collar forward to allow the user to lean forward.

Dans la pratique du ski alpin, l'utilisateur est parfois amené à marcher sur une courte distance afin de rejoindre le sommet d'une piste de ski, par exemple lorsque la montée s'effectue en téléphérique. La grande rigidité de la chaussure conforme au document EP-A-0 406 212 rend la pratique de la marche difficile car les mouvements de la cheville sont bloqués par la chaussure.In alpine skiing, the user is sometimes required to walk a short distance to reach the top of a ski slope, for example when the climb is by cable car. The high rigidity of the shoe conforms to the document EP-A-0 406 212 makes the practice of walking difficult because the movements of the ankle are blocked by the shoe.

Les skis de randonnée sont équipés de fixations autorisant la chaussure à pivoter autour de son extrémité avant, de manière à permettre au talon de se soulever. Ce mouvement implique une flexion et une extension longitudinales de la cheville, ce qui n'est pas permis par les chaussures de ski alpin.The touring skis are equipped with bindings allowing the boot to pivot around its front end, so as to allow the heel to lift. This movement involves longitudinal flexion and extension of the ankle, which is not allowed by alpine ski boots.

Les chaussures de ski de randonnée sont équipées d'un mécanisme de déverrouillage de la rotation du collier vers l'arrière, afin de faciliter la marche d'approche en autorisant la flexion et l'extension longitudinales de la cheville. Toutefois, le collier n'est pas libre de pivoter latéralement, ce qui bloque les mouvements de flexion latérale de la cheville, appelés inversion et éversion. Ainsi, les chaussures de ski de randonnée ne sont pas adaptés pour réaliser des marches d'approche dans lesquelles le skieur déchausse ses skis et évolue sur un terrain accidenté, ni pour l'alpinisme. D'autre part, les chaussures de ski de randonnée ne sont pas plus adaptée pour les phases de montée dans les zones en dévers qui nécessitent une inclinaison latérale de la chaussure.The ski touring boots are equipped with a mechanism for unlocking the rotation of the collar towards the rear, in order to facilitate the approach walk by allowing longitudinal flexion and extension of the ankle. However, the collar is not free to pivot laterally, which blocks the movements of lateral flexion of the ankle, called inversion and eversion. Thus, the ski touring boots are not suitable for making approaching steps in which the skier unhooks his skis and moves on rough terrain, or mountaineering. On the other hand, ski touring boots are not more suitable for climbing phases in sloping areas that require a lateral inclination of the shoe.

A cet égard, EP-A-0 406 212 décrit un mécanisme permettant de régler l'inclinaison latérale, ou « canting », du collier par rapport à la partie basse de la chaussure, en fonction de la morphologie des jambes du skieur. Ce réglage s'effectue préalablement à la pratique du ski, et il n'est plus modifié lors de l'utilisation de la chaussure. Le réglage du canting n'est pas aisé à réaliser et nécessite souvent un outil.In this regard, EP-A-0 406 212 describes a mechanism for adjusting the lateral inclination or "canting" of the collar relative to the lower part of the boot, depending on the morphology of the skier's legs. This adjustment is made before the practice ski, and it is no longer modified when using the shoe. The setting of the canting is not easy to achieve and often requires a tool.

Dans EP-A-0 406 212 , il est prévu une position libre dans laquelle le collier peut librement s'incliner latéralement. Toutefois, l'amplitude angulaire de ce mouvement est limitée à quelques degrés, et les frottements rendent l'inclinaison latérale difficile. Ainsi, la chaussure selon le document EP-A-0 406 212 n'est pas adaptée pour permettre un mouvement aisé de flexion latérale de la cheville pendant la pratique du ski ni pendant la marche.In EP-A-0 406 212 a free position is provided in which the collar can freely tilt laterally. However, the angular amplitude of this movement is limited to a few degrees, and the friction makes the lateral inclination difficult. So, the shoe according to the document EP-A-0 406 212 is not adapted to allow easy lateral bending of the ankle during skiing or during walking.

Par ailleurs, EP-A-1 880 623 divulgue une chaussure de ski dont l'amplitude de la flexion latérale est augmentée. Au niveau de l'articulation de la cheville, la chaussure comporte deux liaisons de type rotule. Deux mécanismes indépendants de blocage assurent, d'une part, le blocage de la flexion et de l'extension longitudinales de la cheville et, d'autre part, le blocage de la flexion latérale. Ce dispositif est relativement lourd et complexe, et nécessite la présence d'une plaque de couplage volumineuse et saillante. De plus, le collier de la chaussure ne peut pas s'incliner simultanément longitudinalement et latéralement, ce qui limite les mouvements de la cheville.Otherwise, EP-A-1,880,623 discloses a ski boot whose amplitude of lateral flexion is increased. At the level of the ankle joint, the shoe comprises two ball-type links. Two independent locking mechanisms ensure, on the one hand, the locking of the longitudinal flexion and extension of the ankle and, on the other hand, the blocking of the lateral bending. This device is relatively heavy and complex, and requires the presence of a large and protruding coupling plate. In addition, the collar of the shoe can not tilt simultaneously longitudinally and laterally, which limits the movements of the ankle.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant une chaussure de sport permettant à la fois la pratique du ski alpin, du ski de randonnée et de l'alpinisme. L'objectif de l'invention est de proposer une chaussure dans laquelle le collier présente une très grande liberté de mouvements par rapport à la partie basse. Un autre objectif de l'invention est de proposer une chaussure suffisamment légère pour permettre la pratique de la marche, de l'alpinisme, voire de l'escalade, tout en étant suffisamment rigide pour assurer un maintien correct de la jambe lors de la pratique du ski, notamment en vue de l'appui de la jambe sur l'arrière du collier.It is to these drawbacks that the invention more particularly intends to remedy by proposing a sports shoe allowing both the practice of alpine skiing, ski touring and mountaineering. The object of the invention is to provide a shoe in which the collar has a great freedom of movement relative to the lower part. Another object of the invention is to provide a shoe light enough to allow the practice of walking, mountaineering, or even climbing, while being rigid enough to ensure proper leg support during practice ski, especially for the support of the leg on the back of the collar.

A cet effet, l'invention a pour objet une chaussure de sport selon la revendication 1. D'autres concrétisations sont divulguées dans les revendications dépendantes 2-11.For this purpose, the invention relates to a sports shoe according to claim 1. Other embodiments are disclosed in the dependent claims 2-11.

Grâce à l'invention, le collier est libre de s'incliner latéralement et longitudinalement, de manière simultanée, par rapport à la partie basse lorsque l'élément de blocage est dans la position de déblocage. De plus, le blocage du collier s'effectue de manière aisée au moyen de l'élément de blocage. Par ailleurs, chaque partie du collier s'articule avec la partie basse autour d'un axe transversal perpendiculaire à un plan médian de la chaussure, ce qui permet de reproduire de manière anatomique le mouvement de flexion longitudinal de la cheville. En outre, le mouvement relatif de translation des parties du collier l'une par rapport à l'autre permet l'inclinaison latérale du collier par rapport à la partie basse, en position de déblocage, grâce à la souplesse propre des parties du collier, qui travaillent en flexion.Thanks to the invention, the collar is free to tilt laterally and longitudinally, simultaneously, with respect to the lower part when the locking element is in the unlocking position. In addition, the locking of the collar is done easily by means of the locking element. Furthermore, each part of the collar is articulated with the lower part about a transverse axis perpendicular to a median plane of the shoe, which allows to reproduce anatomically the longitudinal flexion movement of the ankle. In addition, the relative movement of the translation of the collar parts relative to each other allows the lateral inclination of the collar relative to the lower part, in unlocking position, thanks to the inherent flexibility of the parts of the collar, who work in flexion.

Les figures 1 à 7 montrent une chaussure de sport 1, adaptée notamment pour la pratique du ski, de randonnée à ski, de l'alpinisme et de la marche. Dans le cas d'espèce, il s'agit d'une chaussure de ski de randonnée.The Figures 1 to 7 show a sports shoe 1, particularly suitable for skiing, ski touring, mountaineering and walking. In this case, it is a ski touring boot.

Dans la suite, les termes « haut », « bas », « avant », « arrière », « vertical » et « horizontal » sont définis en relation avec l'orientation de la chaussure 1 sur la figure 1, qui correspond à une utilisation de la chaussure 1 dans laquelle sa semelle de marche 21 repose sur une surface plane et horizontale.In the following, the terms "up", "down", "forward", "back", "vertical" and "horizontal" are defined in relation to the orientation of the shoe 1 on the figure 1 , which corresponds to a use of the shoe 1 in which its outsole 21 rests on a flat and horizontal surface.

La chaussure 1 comprend une partie basse, ou bas de coque 2, adaptée pour entourer et envelopper le pied d'un utilisateur. Une partie haute de la chaussure 1, ou collier 3, est prévue pour entourer et envelopper le bas de la jambe de l'utilisateur. Le collier 3 est mobile par rapport à la partie basse 2.The shoe 1 comprises a lower part, or bottom shell 2, adapted to surround and envelop the foot of a user. An upper part of the shoe 1, or collar 3, is provided to surround and wrap the bottom of the leg of the user. The collar 3 is movable relative to the lower part 2.

La partie basse 2 s'étend en longueur le long d'un axe longitudinal X-X' de la chaussure 1, entre un talon 23 situé à l'arrière de la chaussure 1, et une pointe 24 située à l'avant de la chaussure 1. La partie basse 2 comprend des flancs latéraux 22A et 22B globalement verticaux issus de la semelle 21. Les flancs latéraux 22A et 22B définissent avec la semelle 21 une cavité prévue pour recevoir le pied de l'utilisateur. Une zone supérieure de la partie basse délimite une ouverture 25 prévue pour l'introduction du pied.The lower part 2 extends in length along a longitudinal axis XX 'of the shoe 1, between a heel 23 located at the rear of the shoe 1, and a tip 24 located at the front of the shoe 1 The lower part 2 comprises generally vertical lateral flanks 22A and 22B coming from the soleplate 21. The lateral flanks 22A and 22B define with the soleplate 21 a cavity designed to receive the foot of the user. An upper zone of the lower part delimits an opening 25 provided for the introduction of the foot.

La partie basse 2 et le collier 3 comprennent chacun une coque 20 ou 30 rigide. Les coques 20 et 30 sont généralement réalisées dans des matériaux synthétiques, par exemple en matière plastique ou composite, et le chausson 4 est généralement confectionné en assemblant plusieurs panneaux de mousse ou de tissu.The lower part 2 and the collar 3 each comprise a shell 20 or rigid 30. The shells 20 and 30 are generally made of synthetic materials, for example plastic or composite, and the liner 4 is generally made by assembling several panels of foam or fabric.

Des premiers moyens de serrage 26, par exemple des lacets 262 et un élément de serrage 264, permettent de serrer les flancs latéraux 22A et 22B l'un contre l'autre afin de maintenir fermement le pied de l'utilisateur dans la partie basse 2. En variante, des crochets ou tout autre moyen de serrage peuvent être utilisés en remplacement ou en complément des lacets 262 et de l'élément de serrage 264.First clamping means 26, for example laces 262 and a clamping member 264, allow the side flanks 22A and 22B to be clamped against each other to firmly hold the user's foot in the lower part 2 Alternatively, hooks or other clamping means may be used instead of or in addition to the laces 262 and the clamping member 264.

Le collier 3 s'étend en hauteur entre un bord inférieur 31, qui délimite une ouverture qui débouche dans l'ouverture 25 de la partie basse 2, et un bord supérieur 32, qui délimite une ouverture 33 prévue pour l'introduction du pied de l'utilisateur dans la chaussure 1. Au niveau de l'ouverture 33, le chausson 4 dépasse à l'extérieur de la coque 30 pour des raisons de confort.The collar 3 extends in height between a lower edge 31, which defines an opening which opens into the opening 25 of the lower part 2, and an upper edge 32, which defines an opening 33 provided for the introduction of the foot of the user in the shoe 1. At the opening 33, the liner 4 protrudes outside the hull 30 for reasons of comfort.

Le collier 3 comprend une première partie 34A latérale et une deuxième partie 34B médiale, qui prolongent les flancs latéraux 22A et 22B de la partie basse 2 vers le haut.The collar 3 comprises a first lateral portion 34A and a second medial portion 34B, which extend the lateral flanks 22A and 22B of the lower part 2 upwards.

Les parties 34A et 34B sont deux pièces mécaniques distinctes, autrement dit disjointes. Les parties 34A et 34B sont séparées entre elles par une fente 35 du collier 3 située au dessus du talon, en partie arrière de la chaussure 1, à travers laquelle le chausson 4 est visible. En position de blocage, et en position de déblocage lorsque le collier 3 s'étend en longueur perpendiculairement à la semelle 21, les parties 34A et 34B s'étendent de part et d'autre d'un plan médian M de la chaussure 1, orienté verticalement, qui passe par l'axe longitudinal X-X' et qui partage la chaussure 1 en une partie latérale et une partie médiale.Parts 34A and 34B are two separate mechanical parts, in other words disjointed. The parts 34A and 34B are separated from each other by a slot 35 of the collar 3 located above the heel, in the rear part of the boot 1, through which the liner 4 is visible. In the locking position, and in the unlocking position when the collar 3 extends in length perpendicularly to the soleplate 21, the portions 34A and 34B extend on either side of a median plane M of the boot 1, vertically oriented, which passes through the longitudinal axis XX 'and which shares the shoe 1 in a lateral portion and a medial portion.

Chaque partie 34A et 34B est articulée en rotation avec un flanc 22A ou 22B de la partie basse 2, au niveau d'une zone correspondant à la malléole de l'utilisateur, au moyen d'un rivet 3420A ou 3420B de forme allongée formant des premiers et seconds moyens d'articulation. Chaque partie 34A et 34B comprend une partie inférieure, ou palier 342A ou 342B, articulé en rotation avec la partie basse 2, autour d'un axe A3 globalement horizontal et perpendiculaire au plan médian M. L'axe A3 est commun aux deux paliers 342A et 342B. Les paliers 342A et 342B s'étendent en longueur de part et d'autre d'un axe A342, qui a une direction radiale par rapport à l'axe A7.Each portion 34A and 34B is articulated in rotation with a flank 22A or 22B of the lower part 2, at a zone corresponding to the malleolus of the user, by means of an elongate rivet 3420A or 3420B forming first and second articulation means. Each part 34A and 34B comprises a lower part, or bearing 342A or 342B, articulated in rotation with the lower part 2, around a generally horizontal axis A3 and perpendicular to the median plane M. The axis A3 is common to the two bearings 342A and 342B. The bearings 342A and 342B extend in length on either side of an axis A342, which has a direction radial with respect to the axis A7.

Dans l'exemple représenté, les paliers 342A et 342B sont rectilignes. En variante, ils peuvent être courbés. Dans ce cas, l'axe A342 est également courbé.In the example shown, the bearings 342A and 342B are rectilinear. Alternatively, they can be bent. In this case, the axis A342 is also curved.

Chaque palier 342A est prolongé vers le haut par une partie supérieure 344A ou 344B de la partie 34A ou 34B du collier 3 correspondante, qui est prévue pour entourer partiellement le bas de jambe.Each bearing 342A is extended upwardly by an upper portion 344A or 344B of the portion 34A or 34B of the corresponding collar 3, which is provided to partially surround the lower leg.

Les parties 34A et 34B sont formées à partir de plaques minces et légèrement souples et élastiques, de sorte que l'encombrement de la chaussure 1 n'est pas pénalisé.The parts 34A and 34B are formed from thin and slightly flexible and elastic plates, so that the size of the shoe 1 is not penalized.

Des seconds moyens de serrage 36 sont prévus pour serrer le collier 3 sur le bas de la jambe de l'utilisateur. Les seconds moyens de serrage 36 comprennent une bande crantée 362 métallique, fixée sur la partie supérieure 344B de la partie médiale 34B, ainsi qu'un crochet de serrage 364, fixé sur la partie supérieure 344A de la partie latérale 34A.Second clamping means 36 are provided for clamping the collar 3 on the lower leg of the user. The second clamping means 36 comprise a notched band 362 metal, fixed on the upper portion 344B of the medial portion 34B, and a clamping hook 364, fixed on the upper portion 344A of the side portion 34A.

Chaque partie 34A et 34B comporte un premier bord ou bord interne 346A ou 346B, qui est parallèle au plan médian M en position de blocage, ainsi qu'en position de déblocage lorsque le collier 3 s'étend perpendiculairement à la semelle 21. Un deuxième bord 348A ou 348B de chaque partie 34A et 34B est opposé au premier bord 346A ou 346B de la partie 34A ou 34B correspondante.Each portion 34A and 34B comprises a first edge or inner edge 346A or 346B, which is parallel to the median plane M in the locking position, and in the unlocking position when the collar 3 extends perpendicular to the sole 21. A second Edge 348A or 348B of each portion 34A and 34B is opposed to the first edge 346A or 346B of the corresponding portion 34A or 34B.

On note L1, une largeur maximale de chaque palier 342A et 342B, mesurée perpendiculairement à l'axe A342. On note L2, une longueur minimale de chaque palier 342A et 342B, mesurée le long de l'axe A342 entre l'axe A7 et la partie supérieure 344A ou 344B. La longueur L2 est strictement supérieure à la largeur L1. Un rapport ayant, comme dénominateur, la longueur L2 et, comme numérateur, la largeur L1, est compris entre 1,3 et 2,5 de préférence sensiblement égal à 1,5.We denote L1, a maximum width of each bearing 342A and 342B, measured perpendicular to the axis A342. We denote L2, a minimum length of each bearing 342A and 342B, measured along the axis A342 between the axis A7 and the upper part 344A or 344B. The length L2 is strictly greater than the width L1. A report having, as denominator, the length L2 and, as numerator, the width L1 is between 1.3 and 2.5, preferably substantially equal to 1.5.

Un tel rapport entre les dimensions L1 et L2 confère une souplesse propre à chaque partie 34A et 34B, qui autorise un mouvement de flexion latérale F2 de chaque partie 34A et 34B, perpendiculairement au plan médian M.Such a ratio between the dimensions L1 and L2 gives a clean flexibility to each portion 34A and 34B, which allows a lateral flexion movement F2 of each portion 34A and 34B, perpendicular to the median plane M.

La partie supérieure 344A et 344B de chaque partie 34A et 34B est plus large que les paliers 342A et 342B et enveloppe le bas de la jambe de l'utilisateur sur un secteur angulaire βA ou βB, supérieur ou égal à 90°. Les angles βA et βB sont mesurés autour d'un axe Y3, qui est un axe longitudinal du collier 3 correspondant à l'axe central de l'enveloppe cylindrique qui délimite la forme extérieure du collier 3, entre les bords 346A et 348A ou 346B et 348B de la partie 34A ou 34B. Ensemble, les parties supérieures 344A et 344B des parties 34A et 34B entourent de préférence le bas de la jambe sur un secteur angulaire supérieur ou égal à 300°.The upper portion 344A and 344B of each portion 34A and 34B is wider than the bearings 342A and 342B and envelops the lower leg of the user on an angular sector βA or βB, greater than or equal to 90 °. The angles βA and βB are measured around an axis Y3, which is a longitudinal axis of the collar 3 corresponding to the central axis of the cylindrical envelope which delimits the external shape of the collar 3, between the edges 346A and 348A or 346B and 348B of 34A or 34B. Together, the upper portions 344A and 344B of the portions 34A and 34B preferably surround the bottom of the leg over an angular sector greater than or equal to 300 °.

Dans l'exemple représenté sur les figures, les parties supérieures 344A et 344B entourent ensemble le bas de jambe sur environ 360°. Le secteur angulaire βA de la partie latérale 34A est environ égal à 180°, et le secteur angulaire βB de la partie médiale 34B est environ égal à 200°. La partie supérieure 344B de la partie médiale 34B comporte une portion qui chevauche la partie supérieure 344A de la partie latérale 34A sur environ 20°, pour permettre un serrage efficace et confortable du bas de la jambe de l'utilisateur.In the example shown in the figures, the upper parts 344A and 344B together surround the lower leg about 360 °. The angular sector βA of the lateral portion 34A is approximately equal to 180 °, and the angular sector βB of the medial portion 34B is approximately equal to 200 °. The upper portion 344B of the medial portion 34B has a portion that overlaps the upper portion 344A of the side portion 34A about 20 °, to provide an effective and comfortable tightening of the lower leg of the user.

Des moyens de liaison 5 relient mécaniquement la partie latérale 34A à la partie médiale 34B. Les moyens de liaison 5 sont assemblés au niveau des extrémités supérieures des parties 34A et 34B et comprennent une plaque 52 rigide de forme allongée, orientée globalement perpendiculairement au plan médian M, dont chaque extrémité est montée rotative sur la partie supérieure 344A ou 344B de l'une des parties 34A et 34B, de manière à autoriser un pivotement de la plaque 52 contre les parties 34A et 34B. Par exemple, la plaque 52 est assemblée à chaque partie 34A et 34B au moyen de deux rivets 51A et 51B qui traversent chacun la plaque 52 et l'une des partie 34A et 34B et qui forment des troisième et quatrième moyens d'articulation des parties 34A et 34B avec la plaque 52.Connecting means 5 mechanically connect the lateral portion 34A to the medial portion 34B. The connecting means 5 are assembled at the upper ends of the portions 34A and 34B and comprise a rigid plate 52 of elongated shape, oriented generally perpendicularly to the median plane M, each end of which is rotatably mounted on the upper portion 344A or 344B of the one of the parts 34A and 34B, so as to allow a pivoting of the plate 52 against the parts 34A and 34B. For example, the plate 52 is assembled at each portion 34A and 34B by means of two rivets 51A and 51B which each pass through the plate 52 and one of the parts 34A and 34B and which form third and fourth articulation means of the parts 34A and 34B with plate 52.

La chaussure 1 inclut des moyens de blocage au moins partiel des mouvements de la partie basse 2 par rapport au collier 3. Ces moyens de blocage comprennent un élément de blocage 7, incluant un dosseret 71 qui est mobile entre une position de blocage représentée aux figures 1, 3 et 6, et une position de déblocage représentée aux figures 2, 4, 5 et 7. Aux figures 6 et 7, l'élément de blocage 7 n'est pas représenté.The boot 1 includes means for blocking at least part of the movements of the lower part 2 relative to the collar 3. These locking means comprise a locking element 7, including a backsplash 71 which is movable between a locking position shown in FIGS. figures 1 , 3 and 6 , and an unlock position represented at figures 2 , 4 , 5 and 7 . the Figures 6 and 7 the blocking element 7 is not shown.

Le dosseret 71 est articulé en rotation avec la partie basse 2, au dessus d'une zone correspondant au talon de l'utilisateur. Le dosseret 71 est de forme incurvée, de manière à entourer partiellement la partie arrière du bas de jambe. Les moyens d'articulation du dosseret 71 avec le bas de coque 2 comprennent un palier 72 fixé sur l'extrémité inférieure du dosseret 71, ainsi qu'une patte 73 fixée au bas de coque 2. Ces éléments ne sont pas représentés aux figures 6 et 7. La patte 73 est pourvue d'un orifice de passage d'un arbre 74 supporté par le palier 72. L'arbre 74 est orienté selon un axe A7 globalement perpendiculaire au plan médian M. Ainsi, l'élément de blocage 7 est articulé en rotation par rapport au bas de coque 2 autour de l'axe A7.The backsplash 71 is articulated in rotation with the lower part 2, above an area corresponding to the heel of the user. The backsplash 71 is curved in shape, so as to partially surround the rear part of the lower leg. The hinge means of the backsplash 71 with the bottom shell 2 comprise a bearing 72 fixed on the lower end backsplash 71, and a tab 73 attached to the shell bottom 2. These elements are not represented in Figures 6 and 7 . The tab 73 is provided with a through hole of a shaft 74 supported by the bearing 72. The shaft 74 is oriented along an axis A7 generally perpendicular to the median plane M. Thus, the locking element 7 is hinged in rotation relative to the shell bottom 2 around the axis A7.

De manière optionnelle, une sangle supplémentaire de serrage, non représentée, est fixée à chaque partie 34A et 34B du collier 3, au moyen des rivets 51A et 51B. La sangle est apte à entourer le collier 3 et est pourvue de moyens de serrage, tels qu'une boucle et des bandes auto-agrippantes.Optionally, an additional tightening strap, not shown, is attached to each portion 34A and 34B of the collar 3, by means of the rivets 51A and 51B. The strap is able to surround the collar 3 and is provided with clamping means, such as a loop and self-gripping strips.

L'élément de blocage 7 est disposé à l'extérieur des coques 20 et 30 de la partie basse 2 et du collier 3, par rapport au volume intérieur de réception du pied de l'utilisateur. La coque 30 du collier 3 est formée par les parties 34A et 34B.The locking element 7 is disposed outside the shells 20 and 30 of the lower part 2 and the collar 3, with respect to the interior receiving volume of the user's foot. The shell 30 of the collar 3 is formed by the portions 34A and 34B.

L'élément de blocage 7 est équipé de moyens de verrouillage 8 de l'élément de blocage dans la position de blocage. Les moyens de verrouillage 8 comprennent un levier 81 articulé en rotation avec le dosseret 71, autour d'un axe A8 globalement perpendiculaire au plan médian M. Le levier 81 comporte une lumière traversante 812 pour le passage d'un câble 82 dont chaque extrémité est fixée à l'une des parties 34A et 34B.The locking element 7 is equipped with locking means 8 of the locking element in the locking position. The locking means 8 comprise a lever 81 articulated in rotation with the backsplash 71, about an axis A8 generally perpendicular to the median plane M. The lever 81 comprises a through-light 812 for the passage of a cable 82, each end of which is attached to one of Parts 34A and 34B.

En outre, les moyens de verrouillage 8 comprennent deux pions 85A et 85B fixés respectivement à la partie 34A ou 34B qui, dans la position de blocage, viennent se loger chacun dans un orifice 86A ou 86B réalisé dans le dosseret 71. En variante, chaque partie 34A ou 34B et le pion 85A ou 85B correspondant est monobloc, c'est-à-dire en une seule pièce.In addition, the locking means 8 comprise two pins 85A and 85B respectively fixed to the portion 34A or 34B which, in the locking position, are each housed in a hole 86A or 86B made in the backsplash 71. In a variant, each part 34A or 34B and the corresponding pin 85A or 85B is monobloc, that is to say in one piece.

Les trois éléments distincts que constituent l'élément de blocage 7, la partie latérale 34A et la partie médiale 34B sont tous les trois articulés par rapport à la partie basse 2. Ils le sont depuis des positions différentes, au niveau des malléoles pour les parties 34A et 34B, et à l'arrière du pied pour l'élément de blocage 7.The three distinct elements constituted by the blocking element 7, the lateral part 34A and the medial part 34B are all articulated with respect to the lower part 2. They are from different positions, at the level of the malleoli for the parts 34A and 34B, and at the back of the foot for the locking element 7.

Dans la position de blocage, représentée aux figures 1, 3 et 6, le levier 81 est rabattu contre la zone arrière de la chaussure 1 et les pions 85A et 85B sont reçus dans les orifices 86A et 86B, de manière à verrouiller les mouvements du collier 3 par rapport à la partie basse 2.In the blocking position, shown in figures 1 , 3 and 6 , the lever 81 is folded against the rear zone of the boot 1 and the pins 85A and 85B are received in the orifices 86A and 86B, so as to lock the movements of the collar 3 relative to the lower part 2.

Lorsque les pions 85A et 85B sont reçus sans jeu dans les orifices 86A et 86B, l'ensemble formé par les partie 34A et 34B, le levier 7 et la partie basse 2 sont parfaitement immobilisés les uns par rapport aux autres.When the pins 85A and 85B are received without play in the holes 86A and 86B, the assembly formed by the parts 34A and 34B, the lever 7 and the lower part 2 are perfectly immobilized relative to each other.

Dans la position de blocage, les mouvements de la cheville de l'utilisateur sont bloqués. Ainsi, la position de blocage est adaptée à la pratique du ski de piste, pour laquelle il est souhaitable d'avoir un blocage de la cheville.In the blocking position, the movements of the user's ankle are blocked. Thus, the blocking position is adapted to the practice of ski trail, for which it is desirable to have a lock of the ankle.

A proximité de l'axe A8, le levier 81 comporte une partie en saillie 84A formant une came qui, lorsque le levier 81 est basculé en position de déverrouillage, décale le dosseret afin qu'il ne soit plus en contact avec les parties 34A et 34B et empêche le levier 81 de revenir en position de blocage. Dans un mode de réalisation alternatif non représenté, la partie en saillie 84A ne vient pas directement au contact avec les parties 34A et 34B mais d'une lame ressort qui elle-même vient pousser les parties 34A et 34B. On peut par exemple envisager que cette lame ressort soit fixée à l'intérieur du dosseret, au dessus du point de fixation du levier et qu'il s'étende vers le bas en dessous de ce même point. La longueur de la lame ressort permet alors d'augmenter l'amplitude du décalage entre le dosseret et le collier. La lame ressort assure également une énergisation du levier qui rend stable la position ouverte de celui-ci.Near the axis A8, the lever 81 has a projecting portion 84A forming a cam which, when the lever 81 is tilted in the unlocking position, shifts the backrest so that it is no longer in contact with the parts 34A and 34B and prevents the lever 81 from returning to the blocking position. In an alternative embodiment not shown, the projecting portion 84A does not come into direct contact with the parts 34A and 34B but a spring blade which itself pushes the parts 34A and 34B. For example, it is conceivable for this spring blade to be fixed inside the backsplash, above the attachment point of the lever and to extend downward below this point. The length of the spring blade then makes it possible to increase the amplitude of the offset between the backsplash and the collar. The spring blade also provides an energizing lever that makes the open position of the lever stable.

Pour passer de la position de blocage à la position de déblocage, le levier 81 est rabattu vers le haut dans une position de déverrouillage, comme indiqué par la flèche F3 à la figure 4. Les parties en saillie 84A et 84B appuient contre chaque partie 34A et 34B, de manière à repousser les parties 34A et 34B contre le chausson 4, ce qui a pour effet de repousser les pions 85A et 85B hors des orifices 86A et 86B.To move from the blocking position to the unlocking position, the lever 81 is folded upwards into an unlocking position, as indicated by the arrow F3 at the figure 4 . The projecting portions 84A and 84B press against each portion 34A and 34B, so as to push the portions 34A and 34B against the liner 4, which has the effect of pushing the pins 85A and 85B out of the holes 86A and 86B.

La figure 4a décrit une variante de construction de la chaussure selon l'invention. Une lame flexible 712 est fixée sur la face intérieure du dosseret 71 à proximité du levier 81. Dans la variante décrite, la lame flexible 712 est métallique et elle est fixée par un rivet 713 au-dessus de l'ouverture ménagée dans le dosseret qui permet le passage de la partie en saillie 84A du levier 81.The figure 4a describes an alternative construction of the shoe according to the invention. A flexible blade 712 is fixed on the inner face of the backrest 71 near the lever 81. In the variant described, the flexible blade 712 is metallic and is fixed by a rivet 713 above the opening in the backrest which allows the passage of the projecting portion 84A of the lever 81.

La lame flexible 712 assure deux fonctions distinctes. Tout d'abord, elle permet d'augmenter le bras du levier de la partie en saillie 84A de manière à éloigner, plus encore, le dosseret 71 des parties 34A et 34B du collier. D'autre part, elle assure une fonction de ressort qui contraint la rotation du levier 81.The flexible blade 712 provides two distinct functions. Firstly, it makes it possible to increase the arm of the lever of the protruding part 84A so as to move, even more, the backsplash 71 from the parts 34A and 34B of the collar. On the other hand, it provides a spring function which forces the rotation of the lever 81.

Dans la position de déblocage, représentée aux figures 2, 5 et 7, les pions 85A et 85B sont à l'extérieur des orifices 86A et 86B, de manière à laisser libres les mouvements des parties 34A et 34B et de l'élément de blocage 7, et par conséquent également les mouvements du collier 3 par rapport à la partie basse 2.In the unblocking position, shown in figures 2 , 5 and 7 , the pins 85A and 85B are outside the orifices 86A and 86B, so as to leave free the movements of the parts 34A and 34B and the locking element 7, and consequently also the movements of the collar 3 with respect to the lower part 2.

Dans la position de déblocage, un mouvement de flexion longitudinale du collier 3 vers l'arrière, par rapport à la partie basse 2, est autorisé. Ce mouvement de flexion postérieure est représenté par une première flèche F1 à la figure 2. Il s'agit d'une rotation autour de l'axe A3, perpendiculairement au plan médian M.In the unlocking position, a longitudinal bending movement of the collar 3 towards the rear, relative to the lower part 2, is allowed. This posterior flexion movement is represented by a first arrow F1 at the figure 2 . It is a rotation about the axis A3, perpendicular to the median plane M.

Vers l'avant, le mouvement de flexion longitudinale, ou flexion antérieure, est limité par la physiologie de l'articulation de la cheville humaine dont le mouvement de flexion vers l'avant est limité.Forward, the longitudinal flexion movement, or anterior flexion, is limited by the physiology of the human ankle joint whose forward flexion is limited.

On note α1 une amplitude angulaire du mouvement de flexion longitudinale du collier 3 par rapport à la partie basse 2 dans la position de déblocage. L'amplitude angulaire a1 est supérieure à 50°, de préférence encore supérieure à 60°.Α1 is an angular amplitude of the longitudinal bending movement of the collar 3 relative to the lower part 2 in the unlocking position. The angular amplitude a1 is greater than 50 °, more preferably greater than 60 °.

Par ailleurs, dans la position de déblocage, un mouvement de flexion latérale F2 du collier 3 par rapport à la partie basse 2 est autorisé. Dans le référentiel du pied humain et dans un premier sens, il s'agit d'une flexion latérale et, dans l'autre sens, il s'agit d'une flexion médiale. La flexion latérale est une rotation autour d'un axe Y2 parallèle à l'axe longitudinal X-X', situé entre les rivets 3420A et 3420B et inclus dans le plan médian M. Le mouvement de flexion latérale F2 est limité dans un sens et dans l'autre par la rigidité propre de chaque partie 34A et 34B.Moreover, in the unlocking position, a lateral flexion movement F2 of the collar 3 with respect to the lower part 2 is authorized. In the reference system of the human foot and in a first sense, it is a lateral flexion and, in the other direction, it is a medial flexion. The lateral bending is a rotation about an axis Y2 parallel to the longitudinal axis X-X ', located between the rivets 3420A and 3420B and included in the median plane M. The lateral flexion movement F2 is limited in one direction and in the other by the inherent rigidity of each part 34A and 34B.

On note C un contour en forme de quadrilatère, dont les sommets sont définis par les rivets 3420A, 3420B, 51A et 51B. On note γ1, γ2, γ3 et γ4 les angles du quadrilatère. Le côté inférieur C1 du contour C, entre les rivets 3420A et 3420B, reste fixe à la fois dans la position de blocage et dans la position de déblocage, lors des mouvements de flexion longitudinale F1 et latérale F2.C is a quadrilateral shaped outline, the vertices of which are defined by the rivets 3420A, 3420B, 51A and 51B. We write γ1, γ2, γ3 and γ4 the angles of the quadrilateral. The lower side C1 of the contour C, between the rivets 3420A and 3420B, remains fixed both in the locking position and in the unlocking position, during longitudinal flexion movements F1 and lateral F2.

Le mouvement de flexion latérale F2 entraîne en mouvement les trois autres côtés du contour C, à savoir un côté supérieur C2 globalement parallèle au premier côté et situé entre les rivets 51A et 51B, un côté latéral C3 situé entre les rivets 3420A et 51A, et un côté médial C4 situé entre les rivets 3420B et 51B. Les côtés C3 et C4 sont globalement verticaux. Ainsi, les valeurs des angles du quadrilatère défini par le contour C varient lors de la flexion latérale F2.The lateral flexion movement F2 causes the other three sides of the contour C to move in movement, namely an upper side C2 generally parallel to the first side and situated between the rivets 51A and 51B, a lateral side C3 located between the rivets 3420A and 51A, and a medial side C4 located between the rivets 3420B and 51B. The sides C3 and C4 are generally vertical. Thus, the values of the angles of the quadrilateral defined by the contour C vary during lateral flexion F2.

On note α2, une amplitude angulaire du mouvement de flexion latérale F2 du collier 3 par rapport à la partie basse 2, de part et d'autre du plan médian M, dans la position de déblocage. L'amplitude angulaire a2 est comprise entre 10° et 30°, de préférence de l'ordre de 20°.Note α2, an angular amplitude of the lateral flexion movement F2 of the collar 3 relative to the lower part 2, on either side of the median plane M, in the unlocking position. The angular amplitude a2 is between 10 ° and 30 °, preferably of the order of 20 °.

Comme visible à la figure 7, le mouvement F2 de flexion latérale des parties 34A et 34B est combiné simultanément à un mouvement de translation T relative de la partie latérale 34A par rapport à la partie médiale 34B. La translation T est parallèle au bord interne 346A ou 346B de chaque partie 34A et 34B. La translation T comprend une première composante T1 verticale, parallèle au plan médian M et perpendiculaire à la semelle 21, ainsi qu'une deuxième composante T2 transversale, perpendiculaire au plan médian M. Le mouvement de translation T résulte de la flexion des paliers 342A et 342B des parties 34A et 34B. Ainsi, le mouvement de flexion latérale F2 est autorisé par découplage mécanique des parties 34A et 34B, grâce à la fente 35.As visible at figure 7 , the lateral flexure F2 of the portions 34A and 34B is simultaneously combined with a relative translational movement T of the lateral portion 34A with respect to the medial portion 34B. The translation T is parallel to the inner edge 346A or 346B of each portion 34A and 34B. The translation T comprises a first vertical component T1, parallel to the median plane M and perpendicular to the sole 21, and a second transverse component T2, perpendicular to the median plane M. The translational movement T results from the bending of the bearings 342A and 342B of Parts 34A and 34B. Thus, the lateral flexion movement F2 is authorized by mechanical decoupling of the portions 34A and 34B, thanks to the slot 35.

La position de déblocage permet ainsi une très grande liberté de mouvement du collier 3 par rapport à la partie basse 2, ce qui autorise la pratique de la marche, par exemple une marche d'approche dans le cadre de la pratique du ski de randonnée ou de l'alpinisme.The unlocking position thus allows a great freedom of movement of the collar 3 relative to the lower part 2, which allows the practice of walking, for example a walk in the context of the practice of ski touring or mountaineering.

La chaussure 1 est légère grâce à la structure de l'élément de blocage 7 et des moyens de verrouillage 8. Grâce à la structure en deux parties 34A et 34B du collier 3, les mouvements de flexion latérale de la cheville sont autorisés, et l'encombrement de la chaussure 1 est limité.The boot 1 is light thanks to the structure of the locking element 7 and the locking means 8. Thanks to the two-part structure 34A and 34B of the collar 3, the lateral flexion movements of the ankle are authorized, and the Footprint 1 is limited.

L'invention ne se limite pas au mode de réalisation décrit. En particulier, dans le cadre de l'invention, les modes de réalisation décrits et leurs variantes peuvent être combinés entre eux, au moins partiellement.The invention is not limited to the embodiment described. In particular, in the context of the invention, the described embodiments and their variants may be combined with each other, at least partially.
