i Chaussure de sport a dispositif de serrage deplagable La presente invention concerne une chaussure de sport, notamment une chaussure de ski, du type comportant un dispositif de serrage. Un tel dispositif de serrage est destine a maintenir i Sports shoe with removable clamping device The present invention relates to a sports shoe, in particular a ski boot, of the type comprising a tightening device. Such a clamping device is intended to maintain

rapproches deux pans d'une zone d' introduction du pied. approximate two sides of a foot insertion area.

Ce dispositif comprend de maniere connue, une premiere chape sur laquelle est fixee une palette comportant au moins un element d'accrochage et porte par une plaque solidaire de l'un des pans a rapprocher, et une seconde chape situee sur l'autre pan et constituee par un second element d'accrochage correspondent au premier et commande en verrouillage ou en This device comprises in known manner, a first yoke on which is fixed a pallet comprising at least one hooking element and carried by a plate secured to one of the sides to be brought together, and a second yoke located on the other side and constituted by a second hooking element correspond to the first and control in locking or in

deverrouillage par l'intermediaire de ladite palette. unlocking by means of said pallet.

Avec de tels dispositifs, il stavere que le confort de l'utilisateur ne peut pas touj ours etre obtenu. En effet, dans ces dispositifs le levier et element d'accrochage les constituent vent places arbitrairement sur une ligne d' action correspondent a une morphologic standard d'un pied. Or, il est evident que des differences existent d'un individu a un autre, et ctest ainsi par exemple que la ligne d' action precitee puisse, apres serrage des pans de la chaussure, se trouver decalee par rapport aux plis de flexion du pied. Egalement, la morphologic du pied peut etre telle, dans certains cas, a provoquer le desalignement du levier par rapport a ['element d'accrochage, pouvant provoquer des variations de serrage en With such devices, it turns out that the comfort of the user cannot always be obtained. In fact, in these devices the lever and hooking element constitute them wind placed arbitrarily on a line of action correspond to a standard morphology of a foot. However, it is obvious that differences exist from one individual to another, and it is thus for example that the aforementioned line of action can, after tightening the sides of the shoe, be offset with respect to the bending folds of the foot. . Also, the morphology of the foot can be such, in certain cases, to cause the misalignment of the lever with respect to the hooking element, which can cause variations in tightening in

cours d'utilisation de la chaussure. during use of the shoe.

Pour remedier a cet inconvenient, il est connu de realiser de s leviers de manuvre as socies a des moyens de deplacement des chapes du dispositif de serrage pour les placer sur une ligne unique d'action adaptee a la morphologic de l'utilisateur. Le document allemand n 24 14 439 decrit de tels moyens consistent en une glissiere fixe crantee dans laquelle se deplace la chape d'un levier de serrage porteur d'un cable de To remedy this drawback, it is known to make operating levers as companies with means for moving the yokes of the clamping device to place them on a single line of action adapted to the morphology of the user. German document no. 24 14 439 describes such means consist of a fixed notched slide in which the yoke of a clamping lever carrying a cable moves

La liaison entre le levier et la glissiere crantee est realisee par l'intermediaire de deux pieces pincant une platine dans laquelle est realisee la glissiere fixe de guidage, pieces auxquelles est associe un ressort de rappel elastique qui necessite l'emploi d'un instrument fin pour le The connection between the lever and the notched slide is made by means of two pieces pinching a plate in which the fixed guide slide is made, pieces with which is associated an elastic return spring which requires the use of a fine instrument for the

soulever avant de pouvoir effectuer un nouveau reglage. lift before a new adjustment can be made.

Ce dispositif est pour le moins complexe et delicat, notamment en ce qui concerne l' operation de reglage. La presente invention a pour objet de resoudre ['ensemble des inconvenients precites, et concerne a cet effet une chaussure de sport, notamment chaussure de ski du type comportant un dispositif de serrage destine a maintenir rapproches deux pans d'une zone d' introduction du pied d'un utilisateur dans ladite chaussure, lequel dispositif de serrage comprend: - une premiere chape solidaire d'un des deux pans - une deuxieme chape solidaire de l'autre des deux pans, - un dispositif de serrage reliant de facon amovible et adaptable la premiere chape a la deuxieme chape; caracterisee en ce que la premiere chape est montee pivotante sur une platine suivant un premier axe de rotation appele axe d'ancrage, elle-meme montee pivotante sur ledit un des deux pans suivant un deuxieme axe de rotation, parallele This device is at the very least complex and delicate, in particular as regards the adjustment operation. The object of the present invention is to resolve all of the aforementioned drawbacks, and for this purpose relates to a sports boot, in particular a ski boot of the type comprising a tightening device intended to keep two sections of a zone for introducing the foot of a user in said shoe, which clamping device comprises: - a first clevis secured to one of the two sides - a second clevis secured to the other of the two sides, - a clamping device connecting in a removable and adaptable manner the first yoke to the second yoke; characterized in that the first yoke is pivotally mounted on a plate along a first axis of rotation called the anchor axis, itself pivotally mounted on said one of the two sides along a second axis of rotation, parallel

au premier axe de rotation et appele axe de reglage. at the first axis of rotation and called the adjustment axis.

Ainsi, la premiere chape peut prendre par rapport au pan de la chaussure une multitude de positions, toutes situees sur Thus, the first yoke can take a multitude of positions relative to the side of the shoe, all located on

un cercle dont l'axe est l'axe de reglage. a circle whose axis is the adjustment axis.

Dans un mode de realisation prefere de l' invention, le dispositif de serrage est par exemple un mecanisme a crochet, la premiere chape servant au support d'un crochet par l'intermediaire d'une palette et d'un tirant et la deuxieme chape etant constituee d'une cremaillere dont les dents vent susceptibles de cooperer avec le crochet. D'autre part la rotation de la platine est limitee entre deux positions A et B par l' interaction d'un plot faisant saillie a la peripherie de la platine et d'une gorge annulaire. Des moyens de blocage de la rotation de la premiere chape vent egalement prevus qui maintiennent celle-ci orientee dans la direction de la ligne In a preferred embodiment of the invention, the clamping device is for example a hook mechanism, the first yoke serving to support a hook by means of a pallet and a tie rod and the second yoke being constituted by a rack whose teeth wind likely to cooperate with the hook. On the other hand, the rotation of the plate is limited between two positions A and B by the interaction of a stud projecting from the periphery of the plate and an annular groove. Means for blocking the rotation of the first yoke are also provided which keep it oriented in the direction of the line

d' action du serrage.tightening action.

Dans un deuxieme mode de realisation de l' invention, la platine est en outre recue dans une couronne, laquelle peut prendre, par rapport a la chaussure, une pluralite de positions. Ainsi les deux positions A et B entre lesquelles la course de la platine est encadree peuvent avoir differentes situations par rapport a la chaussure D'autres avantages et caracteristiques de l' invention In a second embodiment of the invention, the plate is also received in a crown, which can take, with respect to the shoe, a plurality of positions. Thus the two positions A and B between which the race of the plate is framed can have different situations with respect to the shoe. Other advantages and characteristics of the invention

apparaitront a la lecture de la description qui suit ainsi que will appear on reading the following description as well as

realisation de ['invention.realization of the invention.

La figure 1 decrit une chaussure 1 de ski equipee de plusieurs dispositifs de serrage a crochet 2. De facon connue ces dispositifs comprennent une premiere chape 3 fixee sur le pan externe 31 de la chaussure 1. Sur cette chape 3 est montee une palette 4 laquelle agit par l'intermediaire d'un tirant 5 sur un crochet 6. Le crochet 6 est susceptible de s'accrocher aux differentes positions d'une cremaillere 7 fixee sur une deuxieme chape. La premiere chape 3, la palette 4, le tirant 5 et la cremaillere 7 vent sensiblement alignes de facon a definir la ligne d'action "L" du mecanisme a crochet. La premiere chape 3 est fixee sur une platine 8 montee pivotante autour d'un axe d'ancrage 9. La fixation de la premiere chape et de la platine est effectuee par une vis epaulee 10 liant un FIG. 1 describes a ski boot 1 fitted with several hook tightening devices 2. In known manner these devices comprise a first yoke 3 fixed to the outer face 31 of the boot 1. On this yoke 3 is mounted a pallet 4 which acts through a tie rod 5 on a hook 6. The hook 6 is capable of being hooked to the different positions of a rack 7 fixed on a second yoke. The first yoke 3, the pallet 4, the tie rod 5 and the rack 7 are substantially aligned so as to define the line of action "L" of the hook mechanism. The first yoke 3 is fixed on a plate 8 pivotally mounted about an anchoring axis 9. The first yoke and the plate are fixed by a shoulder screw 10 binding a

point d'ancrage de la chape 3, situe dans la partie de celle- anchor point of clevis 3, located in the part thereof

ci qui est distante du crochet, a une portion peripherique de la platine 8. Un trou taraude 26 est menage dans la platine afin de recevoir la vis epaulee. L' utilisation d' une vis epaulee 10 laisse la possibilite a la chape 3 de pivoter par rapport a la platine 8. Ainsi, lorsque la platine pivote autour de l'axe de reglage 12, le point d'ancrage 11 de la chape 3 est deplace autour de ce meme axe, mais la chape 3 Ci which is distant from the hook, at a peripheral portion of the plate 8. A tap hole 26 is formed in the plate in order to receive the shoulder screw. The use of a shoulder screw 10 leaves the possibility for the yoke 3 to pivot relative to the plate 8. Thus, when the plate pivots about the adjustment axis 12, the anchoring point 11 of the yoke 3 is moved around this same axis, but yoke 3

reste orientee suivant la ligne d' action "L". remains oriented along the action line "L".

Bien entendu, la vis epaulee 10 peut etre remplacee par tout systeme de fixation equivalent sans sortir du cadre de Of course, the shoulder screw 10 can be replaced by any equivalent fixing system without leaving the frame of

l' invention.the invention.

La figure 2 montre une vue en perspective partielle et eclatee du dispositif de serrage selon ['invention. La chape 3 comprend une plage 13 longitudinale sensiblement plane. Deux ailes 14 vent disposees lateralement et perpendiculairement a cette plage 13. Ces ailes vent equipees de trous servant a la fixation de la palette du FIG. 2 shows a partial and exploded perspective view of the clamping device according to the invention. The yoke 3 comprises a substantially flat longitudinal section 13. Two wind wings 14 arranged laterally and perpendicular to this range 13. These wind wings equipped with holes used to fix the pallet of the

dispositif de serrage.clamping device.

Dans une des extremites de la plage 13 est menage un trou qui constitue le point d'ancrage de la chape 3. La chape comprend en outre une lumiere demi-circulaire 15 menagee au centre de la plage 13. La platine 8 comprend un disque 16, une portion cylindrique 17 faisant saillie d'une des faces du disque 16 et ayant le meme axe que celui-ci, et ainsi qu'un plot 18 menage a la peripherie du disque, decentre par rapport a l'axe du disque et faisant saillie de la meme face du In one of the ends of the track 13 is formed a hole which constitutes the anchoring point of the yoke 3. The yoke further comprises a semicircular light 15 made in the center of the range 13. The plate 8 comprises a disc 16 , a cylindrical portion 17 projecting from one of the faces of the disc 16 and having the same axis as the latter, and thus a stud 18 leading to the periphery of the disc, off-center with respect to the axis of the disc and making protruding from the same side of the

disque. Le plot est en correspondence avec le trou taraude 26. disk. The stud is in correspondence with the tap hole 26.

Le dispositif comprend en outre une rondelle 19 comportant une ouverture centrale 20 apte a cooperer avec la portion cylindrique 17 de la platine et une gorge peripherique 21 pouvant recevoir le plot 18 de la platine 8. La rondelle 19 comprend egalement un ergot 22 faisant saillie a la fois The device further comprises a washer 19 comprising a central opening 20 capable of cooperating with the cylindrical portion 17 of the plate and a peripheral groove 21 which can receive the stud 18 of the plate 8. The washer 19 also comprises a lug 22 projecting from that time

radialement et suivant l' axe de la rondelle. radially and along the axis of the washer.

La figure 3 montre une vue de dessous de la platine laissant voir la portion cylindrique 17 ainsi que le plot 18 Figure 3 shows a bottom view of the plate showing the cylindrical portion 17 and the stud 18

Le montage du dispositif de serrage reglable s'effectue comme suit. La rondelle 19 est placee dans un evidement 23 de la coque de la chaussure alpine, de telle facon que l' ergot 22 penetre dans une encoche 24 afin de bloquer cette derriere en rotation par rapport a la chaussure 1. La platine 8 est alors placee sur la rondelle 19 de telle facon que la portion cylindrique 17 penetre l'ouverture centrale 20 et que le plot 18 vienne se loger dans la gorge 21. Un rivet 25 maintient la platine 8 et la rondelle 19 sur la chaussure 1. La chape 3 est alors fixee via la vis epaulee 10 sur la platine 8, de facon telle que l' ergot 22 penetre dans la lumiere 15. L'ordre des etapes du montage est indique ici a titre d'exemple et peut The assembly of the adjustable clamping device is carried out as follows. The washer 19 is placed in a recess 23 in the shell of the alpine boot, in such a way that the lug 22 penetrates into a notch 24 in order to block this back in rotation relative to the boot 1. The plate 8 is then placed on the washer 19 in such a way that the cylindrical portion 17 penetrates the central opening 20 and the stud 18 comes to lodge in the groove 21. A rivet 25 holds the plate 8 and the washer 19 on the shoe 1. The yoke 3 is then fixed via the shoulder screw 10 on the plate 8, in such a way that the lug 22 penetrates into the light 15. The order of the stages of assembly is indicated here by way of example and can

secteur angulaire faisant saillie radialement de la platine 8. angular sector projecting radially from the plate 8.

Ce plot 18 est libre d'un mouvement circulaire dans une gorge annulaire menagee dans une couronne 27. Aux deux extremites de This stud 18 is free to move in a circular manner in an annular groove formed in a crown 27. At the two ends of

la gorge annulaire se trouvent des butees 28, 29. there are stops 28, 29 in the annular groove.

Comme dans le premier mode de realisation de l' invention, la chape 3 est montee a la peripherie de la platine et la rotation de cette derriere permet le passage de la chape d'une position A a une position B. La couronne 27 dans laquelle est menagee la gorge 21 annulaire comprend une pluralite d' indentations 30 radiales et regulierement reparties sur sa circonference, et elle est recue dans un evidement de la coque de la chaussure ayant une forme complementaire. La couronne 21 est indexable dans son evidement et il existe autant de positions differentes de celleci par rapport a la coque qu'il As in the first embodiment of the invention, the yoke 3 is mounted on the periphery of the plate and the rotation of this behind allows the yoke to pass from a position A to a position B. The crown 27 in which is formed the annular groove 21 includes a plurality of indentations 30 radial and regularly distributed around its circumference, and it is received in a recess of the shell of the shoe having a complementary shape. The crown 21 is indexable in its recess and there are as many different positions of this relative to the shell as
