Le levier peut occuper trois positions caractéristiques : une position rabattue sur la chaussure dans laquelle l'étrier (25) est pressé contre la crémaillère et dans laquelle un élément mâle (41) du levier est engagé dans l'élément femelle (10) solidaire de la partie inférieure (1) de la chaussure, une position partiellement relevée dans laquelle les éléments mâle et femelle sont dégagés l'un de l'autre mais l'étrier (25) est encore en prise avec la crémaillère et une position relevée totalement dans laquelle l'étrier est dégagé de la crémaillère, la position intermédiaire étant une position de repos ou de marche et la troisième position une position de réglage.The shoe comprises a rod articulated on a lower part and capable of being immobilized by means of connecting devices comprising a rack (12) integral with the rod (2) and a lever (37) articulated on the rack in two guides in which the axis can move parallel to the rack. The lever has an eccentric hub acting as a cam on a toothed caliper (25). The lever can occupy three characteristic positions: a folded position on the shoe in which the stirrup (25) is pressed against the rack and in which a male element (41) of the lever is engaged in the female element (10) integral with the lower part (1) of the shoe, a partially raised position in which the male and female elements are released from each other but the stirrup (25) is still engaged with the rack and a fully raised position in which the stirrup is released from the rack, the intermediate position being a rest or walking position and the third position an adjustment position.

Description

La présents invention a pour objet une chaussure de ski constituée d'au moins une partie inférieure destinée à entourer le pied et d'une tige articulée sur cette partie inférieure, et comprenant, à l'arrière, des moyens de liaison fntre la tige et la partie inférieure, disposés dans une découpe d'une partie de la tige entourant, au moins, partiellement, la partie inférieure de la chaussure, ces moyens de liaison comprenant un levier susceptible d'occuper au moins deux positions, l'une, rabattue contre la chaussure, dans laquelle la tige est fixée angulairement à la partie inférieure avec un angle d'inclinaison déterminé, et l'autre, relevée, dans laquelle la tige est libre d'osciller, dans certaines limites, sur la partie inférieure, des moyens étant prévus pour modifier l'inclinaison de la tige en position fixée angulairement.The present invention relates to a ski boot consisting of at least a lower part intended to surround the foot and of a rod hinged to said lower part and comprising, at the rear, means for connecting the rod f etween and the lower part, arranged in a cutout of a part of the upper which at least partially surrounds the lower part of the shoe, these connecting means comprising a lever capable of occupying at least two positions, one, folded back against the shoe, in which the upper is angularly fixed to the lower part with a determined angle of inclination, and the other, raised, in which the upper is free to oscillate, within certain limits, on the lower part, means being provided for modifying the inclination of the rod in the angularly fixed position.

Un chaussure de ce type est décrite dans le brevet US 4 349 971 au nom de la déposante. Dans cette exécution antérieure, le levier des moyens de liaison est articulé à son extrémité sur un étrier solidaire de la partie intérieure de ld chaussure et en un point intermédiaire, par un écrou baladeur porté par une tige filetée faisant partie du levier, à l'extrémité d'une biellette articulée sur un étrier solidaire de la tige. En position rabattue, l'axe d'articulation de l'écrou baladeur est situé en-dessous de la droite reliant les deux autres axes d'articulation, maintenant ainsi le levier dans cette position rabattue. La tige filetée solidaire du levier est munie à son extrémité de moyens de préhension permettant de faire tourner cette tige pour déplacer l'écrou baladeur, afin de modifier l'inclinaison de la tige. Si le dispositif permet un réglage très fin de l'inclinaison de la tige, par contre il est relativement délicat et tant l'actionnement du levier que le réglage de l'angle d'inclinaison peuvent s'avérer mal aisés dans la neige. En outre, en position de marche, lorsque la tige oscille sur la partie inférieure de la chaussure, toutes les articulations sont sollicitées et gênent le mouvement de la tige. Il est en outre mal aisé d'introduire dans ce mécanisme une liaison élastique agissant comme amortisseur de chocs.A shoe of this type is described in US Pat. No. 4,349,971 in the name of the applicant. In this execution earlier, the lever of the connection means is articulated at its end to a bracket secured to the inner portion of the shoe d and at an intermediate point by a stop nut carried by a threaded rod forming part of the lever at the end of '' a link articulated on a stirrup secured to the rod. In the folded position, the hinge pin of the sliding nut is located below the right connecting the two other hinge pins, thus maintaining the lever in this folded position. The threaded rod integral with the lever is provided at its end with gripping means making it possible to rotate this rod to move the sliding nut, in order to modify the inclination of the rod. If the device allows a very fine adjustment of the inclination of the rod, on the other hand it is relatively delicate and both the actuation of the lever and the adjustment of the angle of inclination can prove to be difficult in snow. In addition, in the running position, when the upper oscillates on the lower part of the shoe, all the joints are stressed and hinder the movement of the upper. It is also difficult to introduce into this mechanism an elastic connection acting as shock absorber.

Un dispositif simple, n'utilisant ni vis ni écrou, est connu du brevet CH 549 970. Dans ce dispositif, le levier est en forme d'étrier élastique dont les deux bras coudés s'engagent dans des trous de chaque côté d'un élément solidaire de la partie inférieure de la chaussure. Lorsqu'on rabat le levier vers le bas, la tige est libérée, mais simultanément ou perd le réglage de l'angle d'avancée, c'est-à-dire l'inclinaison de la tige.A simple device, using neither screws nor nuts, is known from patent CH 549 970. In this device, the lever is in the form of an elastic stirrup, the two bent arms of which engage in holes on each side of a element secured to the lower part of the shoe. When the lever is folded down, the rod is released, but simultaneously or loses the adjustment of the advance angle, that is to say the inclination of the rod.

La présente invention vise à réaliser des moyens de liaison entre la tige et la partie inférieure de la chaussure n'utilisant aucune pièce de réglage filetée et ne requérant aucune précision dans la fabrication, toutes les pièces devant pouvoir être fabriquées par des moyens simples, de préférence par emboutissage.The present invention aims to provide connecting means between the upper and the lower part of the shoe using no threaded adjustment part and requiring no precision in manufacturing, all parts having to be able to be manufactured by simple means, preferably by stamping.

La chaussure de ski est caractérisée par le fait que les desdits moyens de liaison comprennent une crémaillère solidaire de la tige et s'étendant dans le sens de la tige, un levier muni d'un moyeu excentrique, articulé autour d'un axe horizontal monté dans deux guidages latéraux parallèles à la crémaillère et ménagés dans deux joues solidaires de la crémaillère, dans lesquels ledit axe peut se déplacer parallèlement à la crémaillère, un étrier monté sur ledit axe par deux lumières perpendiculaires à la crémaillère, et dont la face médiane, en regard de la crémaillère, présente des dents, un élément mâle solidaire du levier et coopérant par emboîtement avec un élément femelle solidaire de la partie inférieure de la chaussure, ou inversément, ledit levier pouvant occuper trois positions caractéristiques, à savoir une position rabattue sur la chaussure dans laquelle son moyeu excentrique presse ledit étrier contre la crémaillère et dans laquelle les éléments mâle et femelle sont emboités l'un dans l'autre, une position partiellement relevée dans laquelle les éléments mâle et femelle sont dégagés l'un de l'autre, mais ledit moyeu excentrique est encore en appui contre ledit étrier, et une position relevée à au moins 90* dans laquelle ledit étrier n'est pas pressé cor.tre la crémaillère.The ski boot is characterized in that the said connecting means comprise a rack integral with the rod and extending in the direction of the rod, a lever provided with an eccentric hub, articulated around a horizontal axis mounted in two lateral guides parallel to the rack and formed in two cheeks integral with the rack, in which said axis can move parallel to the rack, a stirrup mounted on said axis by two slots perpendicular to the rack, and the median face of which, opposite the rack, has teeth, a male element secured to the lever and cooperating by interlocking with a female element secured to the lower part of the shoe, or vice versa, said lever being able to occupy three characteristic positions, namely a position folded over the shoe in which its eccentric hub presses said stirrup against the rack and in which the male and female elements are fitted one inside the other, a partially raised position in which the male and female elements are released from each other, but said eccentric hub is still in abutment against said caliper, and a position raised to at least 90 * in which said stirrup is not pressed cor.tre the rack.

Grâce à l'utilisation d'un excentrique formant came de serrage, il est possible de relever partiellement le levier pour libérer la tige, sans perdre toutefois le réglage de la position avancée. La présence de cet excentrique permet en outre de réaliser les guidages et les lumières sans grande précision, un jeu ne nuisant absolument pas au bon fonctionnement du dispositif.Thanks to the use of an eccentric forming a clamping cam, it is possible to partially raise the lever to release the rod, without however losing the adjustment of the advanced position. The presence of this eccentric also makes it possible to produce the guides and the lights without great precision, a clearance which in no way detracts from the proper functioning of the device.

Selon une forme d'exécution préférée de l'invention, ledit élément mâle est constitué par une sphère montée rotativement sur un axe horizontal parallèle à la crémaillère et ledit élément femelle est un logement de forme cylindrique muni de deux fentes latérales pour le passage de l'axe de la sphère. Ces fentes sont relativement larges par rapport à l'axe de la sphère, le tout de manière à autoriser un réglage de l'inclinaison latérale (cant) de la tige relativement à la semelle de la chaussure.According to a preferred embodiment of the invention, said male element is constituted by a sphere rotatably mounted on a horizontal axis parallel to the rack and said female element is a cylindrical housing provided with two lateral slots for the passage of the axis of the sphere. These slots are relatively wide with respect to the axis of the sphere, the whole so as to allow an adjustment of the lateral inclination (cant) of the upper relative to the sole of the shoe.

Selon cette même exécution préférée de l'invention. le levier est constitué de deux parties emboitées l'une dans l'autre et accrochées l'une à l'autre avec interposition d'un élément élastique entre les parties accrochantes, de telle sorte que le levier présente une certaine élasticité en traction, amortissant ainsi les chocs sur la jambe, le levier étant toutefois rigide en compression, ce qui est plus favorable pour la pratique du ski.According to this same preferred embodiment of the invention. the lever consists of two parts fitted into one another and hooked to one another with the interposition of an elastic element between the hanging parts, so that the lever has a certain elasticity in traction, damping thus the shocks on the leg, the lever being however rigid in compression, which is more favorable for the practice of skiing.

Selon une autre forme d'exécution ledit élément mâle est constatue par une barrette horizontale solidaire du levier et s'engageant à force dans la rainure d'un bloc de matiére élastique solidaire de la partie inférieure de is chaussure.According to another embodiment, said male element is noted by a horizontal bar secured to the lever and engaging by force in the groove of a block of elastic material secured to the lower part of the shoe.

La chaussure de ski représentée à la figure 1 est en matière synthétique moulée. Elle est constituée, de manière connue en soi, d'une partie inférieure 1 ou coque comprenant la semelle et l'empeigne et d'une tige 2 articulée sur la coque 1 en deux points opposés 3, dont l'un seulement est visible sur le dessin. Le bord supérieur 1a de la partie 1 est entouré largement par la tige 2 à l'avant et à l'arrière de cette tige. Pour sa fermeture, la chaussure est munie de manière connue de quatre boucles 4. La coque 1 et la tige 2 sont en outre reliées l'une à l'autre par de moyens de liaison 5 encastrés dans une découpe rectangulaire 2a de la tige 2.The ski boot shown in Figure 1 is made of molded synthetic material. It consists, in a manner known per se, of a lower part 1 or shell comprising the sole and the upper and of a rod 2 articulated on the shell 1 at two opposite points 3, only one of which is visible on the drawing. The upper edge 1a of the part 1 is surrounded largely by the rod 2 at the front and at the rear of this rod. For its closure, the shoe is provided in a known manner four loops 4. The shell 1 and the rod 2 are further connected to each other by connecting means 5 embedded in a rectangular cutout 2a of the rod 2.

Ces moyens de liaison 5 sont représentés à la figure 2. Ils comprennent une pièce moulée en aluminium 6 fixée au moyen de deux pattelettes 7 à la coque 1 au moyen de rivets. Cette pièce moulée 6 présente une partie cylindrique 8 fendue par une fente diamétrale 9 sur pratiquement toute sa hauteur et dont l'extrémité présente un léger cran 10. Dans la découpe 2a de la tige est fixée une pièce métallique 11 obtenue par découpage et pliage d'une tôle de manière à présenter quatre parois latérales 12, 13, 14 et 15 perpendiculaires à un fond 16, à la manière d'un boitier. Cette pièce 11 est maintenue dans la découpe 2a de la tige, en haut par deux pattelettes latérales 17 et 18 s'engageant sous la tige et par un bord coudé 19 de la face 13 et, en bas, par une vis vissée dans un trou taraudé 20 de la face 15. Les grandes faces parallèles 12 et 14 présentent en outre deux lumières opposées rectangulaires 21 et 22 s'étendant parallèlement au fond 16. Dans ce fond 16 est formée une crémaillère 23, par exemple par matriçage. En-dessous de cette crémaillère, le fond 16 présente une découpe oblongue 24 dans laquelle s'engage librement la partie cylindrique 8 de la pièce 6.These connecting means 5 are shown in Figure 2. They comprise an aluminum molded part 6 fixed by means of two legs 7 to the shell 1 by means of rivets. This molded part 6 has a cylindrical part 8 split by a diametrical slot 9 over almost its entire height and the end of which has a slight notch 10. In the cutout 2a of the rod is fixed a metal piece 11 obtained by cutting and folding d 'a sheet so as to have four side walls 12, 13, 14 and 15 perpendicular to a bottom 16, in the manner of a housing. This part 11 is held in the cutout 2a of the rod, above by two lateral tabs 17 and 18 engaging under the rod and by a bent edge 19 of the face 13 and, below, by a screw screwed in a hole tapped 20 on the face 15. The large parallel faces 12 and 14 also have two opposite rectangular openings 21 and 22 extending parallel to the bottom 16. In this bottom 16 is formed a rack 23, for example by stamping. Below this rack, the bottom 16 has an oblong cut 24 in which the cylindrical part 8 of the part 6 engages freely.

Les moyens de liaison comprennent en outre un étrier 25 présentant une denture 26 en regard de la crémaillère 23 et parallèle aux dents de cette crémaillère. Les ailes de l'étrier 25 présentent deux lumières carrées 27 et 28 situées en face des lumières 21 et 22 de la pièce 11, Dans ces iumières 27 et 28, s'engagent librement les extrémités carrées d'un axe 29. Ces extrémités sont également engagées dans les lumiéres 21 et 22 de la piéce 11. Entre les ailes de l'étrier 25, l'axe 29 est de section circulaire et traverse librement le levier 30 constitué de deux parties 31 et 32 emboitées l'une dans l'autre et accorchées l'une à l'autre. Ces deux parties 31 et 32 sont en tôle métallique découpée et pliée. La partie 31 présente une face frontale 33 de chaque côté de laquelle s'étendent deux ailes traversées par la partie cylindrique de l'axe 29 et dont les extrémités inférseures sont munies de deux pattes coudées en angle droit 34 et 35. La partie inférieure 32 présente une extrémité supérieure 36 coudée à angle droit, une extrémité inférieure 37 légèrement recourbée de manière à permettre la préhension du levier et deux ailes parallèles 38 et 39 entre lesquelles est monté un axe 40 sur lequel est montée une sphère en matière synthétique, de préférence en matière synthétique auto-lubrifiante tel que du DELRIN (marque déposée), libre en rotation sur l'axe 40. La face supérieure de la partie coudée 36 prend appui contre une pièce 42 en matière synthétique, par exemple également en DELRIN, formant le moyeu du levier 30 sur l'axe 29. Ce moyeu 42 présente, du côté de l'étrier 25, une surface cylindrique 43 centrée par rapport à l'axe 29, mais coupée par un plan incliné 42a de manière à constituer une came de serrage. Le reste de la surface du moyeu 42 est constitué de faces planes adaptées aux faces des pièces 31 et 32. Entre les pattes 34 et 35 d'une part et la partie coudée 36 de l'autre partie du levier est disposé un bloc de matière élastomère 44 donnant au levier 30 une certaine élasticité en traction. La partie 32 du levier est en appui contre le moyeu dur 42, de sorte que le levier 30 ne présente pas d'élasticité en compression. Les pièces 31 et 32 du levier 30 sont donc simplement fixées ensemble par emboîtage et accrochage par leurs parties 36 et 34/35 avec interposition d'un élément élastique.The connecting means further comprise a stirrup 25 having a toothing 26 facing the rack 23 and parallel to the teeth of this rack. The wings of the stirrup 25 have two square lights 27 and 28 located opposite the lights 21 and 22 of the part 11, In these channels 27 and 28, freely engage the square ends of an axis 29. These ends are also engaged in the lights 21 and 22 of the room 11. Between the wings of the stirrup 25, the axis 29 is of circular section and freely crosses the lever 30 consisting of two parts 31 and 32 fitted one inside the other and hooked to one another. These two parts 31 and 32 are made of cut and folded sheet metal. The part 31 has a front face 33 on each side of which extend two wings crossed by the cylindrical part of the axis 29 and whose lower ends are provided with two legs bent at right angles 34 and 35. The lower part 32 has an upper end 36 bent at a right angle, a lower end 37 slightly curved so as to allow the lever to be gripped and two parallel wings 38 and 39 between which is mounted an axis 40 on which is mounted a sphere of synthetic material, preferably in self-lubricating synthetic material such as DELRIN (registered trademark), free to rotate on the axis 40. The upper face of the bent part 36 bears against a piece 42 of synthetic material, for example also DELRIN, forming the hub of the lever 30 on the axis 29. This hub 42 has, on the side of the stirrup 25, a cylindrical surface 43 centered with respect to the axis 29, but cut by an inclined plane 42a so as to consti kill a clamping cam. The rest of the surface of the hub 42 is made up of flat faces adapted to the faces of the parts 31 and 32. Between the legs 34 and 35 on the one hand and the bent part 36 on the other part of the lever is disposed a block of material elastomer 44 giving the lever 30 a certain elasticity in traction. The part 32 of the lever bears against the hard hub 42, so that the lever 30 has no elasticity in compression. The parts 31 and 32 of the lever 30 are therefore simply fixed together by fitting and hooking by their parts 36 and 34/35 with the interposition of an elastic element.

En position fermée des moyens de liaison, tels que représentés en coupe à la figure 3, l'étrier 25 est fortement pressé contre la crémaillère 23 par le moyeu 42 du levier 30 qui agit dans cette position comme came de serrage, l'axe 29 prenant appui contre les extrémités extérieures des lumières 27 et 28. La sphère en plastique 41 est engagée dans le logement cylindrique formé par la pièce 8. La coque 1 et la tige de la chaussure sont ainsi reliées de façon rigide à l'exception de l'élasticité offerte par la pièce en élastomère 44. Le diamètre de la sphère 41 est légèrement supérieur au diamètre de l'entrée de la pièce 8, de manière à assurer une retenue de cette sphère dans son logement. La fente 9 dp la pièce 8 est sensiblement plus large que le diamètre de l'axe 40 de manière à autoriser une certaine rotation du levier 30 autour de l'axe de la partie cylindrique 8, de manière à permettre un réglage de l'inclinaison latérale de la tige 2 de la chaussure relativement à la coque 1.In the closed position of the connecting means, as shown in section in FIG. 3, the stirrup 25 is strongly pressed against the rack 23 by the hub 42 of the lever 30 which acts in this position as a clamping cam, the axis 29 bearing against the outer ends of the lights 27 and 28. The plastic sphere 41 is engaged in the cylindrical housing formed by the part 8. The shell 1 and the upper of the shoe are thus rigidly connected with the exception of the 'elasticity offered by the elastomer part 44. The diameter of the sphere 41 is slightly greater than the diameter of the inlet of the part 8, so as to ensure retention of this sphere in its housing. The slot 9 dp the part 8 is substantially wider than the diameter of the axis 40 so as to allow a certain rotation of the lever 30 around the axis of the cylindrical part 8, so as to allow an adjustment of the inclination lateral of the upper 2 of the shoe relative to the shell 1.

En position de repos ou de marche, il est possible de supprimer la liaison 5 entre la tige et la coque en relevant légèrement le levier 30, comme représenté en traits mixtes à la figure 3, de manière à dégager la sphère 41 de son logement 8. Dans cette position du levier, l'étrier 25 est encore pressé contre la crémaillère 23 par le moyeu 42, de telle sorte que l'inclinaison de la tige choisie pour la pratique du ski est conservée. Ainsi, lorsque le skieur rabat complètement le levier 30 pour la pratique du ski, l'inclinaison de la tige reprend automatiquement la valeur choisie précédemment par le skieur.In the rest or walking position, it is possible to remove the connection 5 between the rod and the shell by slightly raising the lever 30, as shown in phantom in Figure 3, so as to release the sphere 41 from its housing 8 In this position of the lever, the stirrup 25 is still pressed against the rack 23 by the hub 42, so that the inclination of the rod chosen for skiing is preserved. Thus, when the skier completely folds down the lever 30 for skiing, the inclination of the rod automatically takes up the value previously chosen by the skier.

Si le skieur désire modifier l'inclinaison de la tige relativement à la coque, il doit relever le levier 30 plus haut que l'horizontale, comme représenté à la figure 4. Dans cette position, la partie cylindrique 43 du moyeu 42 n'est plus en appui contre le fond de l'étrier 25, en regard duquel se trouve maintenant le plan incliné 42a, de telle sorte que les dents 26 de l'étrier ne sont plus pressées dans la crémaillère 23. Il est dès lors possible de déplacer l'étrier 25 le long des parois 12 et 14 de la pièce 11, l'axe 29 se déplaçant dans les lumières 21 et 22. Une fois la nouvelle position choisie, il suffit de rabattre le levier 30, soit dans la position de pratique du ski, soit dans une position oblique intermédiaire.If the skier wishes to modify the inclination of the rod relative to the hull, he must raise the lever 30 higher than the horizontal, as shown in FIG. 4. In this position, the cylindrical part 43 of the hub 42 is not no longer resting against the bottom of the stirrup 25, opposite which is now the inclined plane 42a, so that the teeth 26 of the stirrup are no longer pressed in the rack 23. It is therefore possible to move the stirrup 25 along the walls 12 and 14 of the part 11, the axis 29 moving in the slots 21 and 22. Once the new position has been chosen, it suffices to fold the lever 30, ie in the practical position ski, either in an intermediate oblique position.

Selon la seconde forme représentée à la figure 5, les moyens de liaison comprennent une pièce métallique 45 en tôle découpée et pliée, analogue à la pièce 11 de la première forme d'exécution et fixée dans la découpe 2a de la tige 2. Cette pièce 45 présente trois côtés 46, 47 et 48 pliés à angle droit relativement à un fond 49 présentant une crémaillère 50. Les côtés 46 et 48 sont parallèles et sont munis de deux lumières rectangulaires 51 et 52 analogues aux lumières 21 et 22 de la première forme d'exécution. Dans un étrier 53, analogue l'étrier 25, est articulée l'extrémité d'un levier 54, constitué par une pièce en métal moulé, dont is moyeu présente également une partis cylindrique 55 suivie d'un dégagement 56. Ce moyeu est monté libre en rotation sur un axe 57 dont les extrémités carrées traversent deux lumières carréssde l'étrier 53 et s'engagent dans les deux lumières 51 et 52 comme dans la première forme d'exécution. Le levier 54 présente une creusure 58 dans laquelle est montée une barrette cylindrique 59 destinée à s'engager dans un bloc d'élastomère 60 fixé dans une pièce en U 61 elle même fixée au moyen d'un rivet 62 à la coque 1. Le bloc en élastomère 60 présente une rainure dont la section a la forme d'un U ou d'un oméga, dans laquelle s'engage la barrette 59. Le bloc en élastomère 60 assure une certaine élasticité de la liaison entre la tige et la coque de la chaussure, aussi bien en traction qu'en compression, Si cette forme d'exécution est montée sur une chaussure présentant des moyens de réglage de l'inclinaison latérale de la tige relativement à la coque, il peut arriver, lorsque le réglage est effectué en position ouverte du dispositif de liaison, que la barrette 59 ne soit plus parallèle à la rainure du bloc 60. Il est toutefois possible d'obvier à cet inconvénient en permettant au support 61 du bloc en élastomère de tourner gras sur son rivet 62 et en réglant l'inclinaison latérale en position fermée des moyens de liaison.According to the second form shown in Figure 5, the connecting means comprise a metal part 45 of cut and folded sheet metal, similar to part 11 of the first embodiment and fixed in the cutout 2a of the rod 2. This part 45 has three sides 46, 47 and 48 folded at right angles relative to a bottom 49 having a rack 50. The sides 46 and 48 are parallel and are provided with two rectangular slots 51 and 52 similar to slots 21 and 22 of the first form of execution. In a stirrup 53, analogous to the stirrup 25, is articulated the end of a lever 54, constituted by a piece of molded metal, of which the hub also has a cylindrical part 55 followed by a clearance 56. This hub is mounted free to rotate on a axis 57 whose square ends pass through two square slots of the stirrup 53 and engage in the two slots 51 and 52 as in the first embodiment. The lever 54 has a recess 58 in which is mounted a cylindrical bar 59 intended to engage in an elastomer block 60 fixed in a U-shaped piece 61 itself fixed by means of a rivet 62 to the shell 1. The elastomer block 60 has a groove whose section has the shape of a U or an omega, in which the bar 59 engages. The elastomer block 60 ensures a certain elasticity of the connection between the rod and the shell of the shoe, both in traction and in compression, If this embodiment is mounted on a shoe having means for adjusting the lateral inclination of the upper relative to the shell, it can happen, when the adjustment is performed in the open position of the connecting device, that the bar 59 is no longer parallel to the groove of the block 60. It is however possible to overcome this drawback by allowing the support 61 of the elastomer block to turn fat on its rivet 62 and adjusting the lateral tilt in closed position of the connecting means.

La présente invention est bien entendu susceptible de nombreuses variantes d'exécution. En particulier, les éléments mâle et femelle peuvent être inversés; dans la première forme d'exécution la bille serait solidaire de la partie inférieure de la chaussure, tandis que la partie cylindrique fendue serait solidaire du levier. Dans la seconde forme d'exécution, le bloc en élastomère pourrait étre monté amoviblement dans son étrier, de maniére pouvoir étre échangé par exemple contre un bloc d'élasticité différente.The present invention is of course susceptible of numerous variant embodiments. In particular, the male and female elements can be reversed; in the first embodiment, the ball would be integral with the lower part of the shoe, while the split cylindrical part is secured to the lever. In the second embodiment, the elastomer block could be removably mounted in its stirrup, so that it can be exchanged, for example, for a block of different elasticity.
