Description

La présente 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 entre la tige et la partie inférieure, ces moyens de liaison comprenant un levier-came susceptible d'occuper au moins deux positions, l'une dans laquelle la tige est fixée angulairement à la partie inférieure de la chaussure avec un angle d'inclinaison déterminé et l'autre 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 dans la position fixée angulairement.The present invention relates to a ski boot consisting of at least one lower part intended to surround the foot and a rod articulated on this lower part, and comprising, at the rear, means of connection between the rod and the lower part, these connecting means comprising a cam lever capable of occupying at least two positions, one in which the upper is angularly fixed to the lower part of the shoe with a determined angle of inclination and the other in which the rod 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 dispositif de ce type est connu du document EP-A-0 134 595. Dans cette chaussure, les moyens de liaison comportent une crémaillère solidaire de la tige et un levier-came articulé sur la crémaillère dans deux guidages dans lesquels l'axe peut se déplacer parallèlement à la crémaillère. Le levier-came présente un moyeu excentrique agissant sur un étrier denté et il peut occuper trois positions caractéristiques : une position rabattue sur la chaussure dans laquelle l'étrier est pressé contre la crémaillère et dans laquelle un élément mâle du levier est engagé dans un élément femelle solidaire de la partie inférieure de la chaussure, une position partiellement relevée dans laquelle les éléments mâle et femelle sont dégagés, mais l'étrier 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. La structure des moyens de liaison permet donc de libérer la tige de la partie inférieure de la chaussure, tout en conservant le réglage de l'inclinaison de la tige, contrairement au dispositif décrit dans le brevet CH 549 970, dans lequel le réglage de l'inclinaison est perdu lorsqu'on rabat le levier vers le bas pour libérer la tige. Toutefois, dans cette chaussure selon l'art antérieur, les moyens de liaison sont encore relativement volumineux et, en position de marche ou de repos, le levier-came, écarté de la chaussure, peut être gênant et il est exposé aux coups.A device of this type is known from document EP-A-0 134 595. In this shoe, the connecting means comprise a rack fixed to the rod and a cam lever articulated on the rack in two guides in which the axis can move parallel to the rack. The cam lever has an eccentric hub acting on a toothed caliper and it can occupy three characteristic positions: a folded position on the shoe in which the caliper is pressed against the rack and in which a male element of the lever is engaged in an element female secured to the lower part of the shoe, a partially raised position in which the male and female elements are released, but the stirrup 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. The structure of the means of connection therefore makes it possible to release the upper from the lower part of the shoe, while retaining the adjustment of the inclination of the upper, unlike the device described in patent CH 549 970, in which the adjustment of the inclination is lost when '' the lever is folded down to release the rod. However, in this shoe according to the prior art, the connecting means are still relatively bulky and, in the on or off position, the cam lever, separated from the shoe, can be troublesome and it is exposed to blows.

Du document DE-A-28 07 371, on connaît par ailleurs une chaussure de ski à tige articulée dans laquelle une inclinaison minimale de la tige est obtenue au moyen d'un excentrique intercalé entre la tige et une butée formée sur la coque de la chaussure. La rotation de l'excentrique permet de régler l'inclinaison minimale désirée dans certaines limites, mais la tige ne peut pas être libérée pour obtenir une position de repos ou de marche.From document DE-A-28 07 371, a ski boot with an articulated rod is also known in which a minimum inclination of the rod is obtained by means of an eccentric interposed between the rod and a stop formed on the shell of the shoe. The rotation of the eccentric allows the desired minimum inclination to be adjusted within certain limits, but the rod cannot be released to obtain a rest or walking position.

La présente invention a pour but de réaliser des moyens de liaison satisfaisant les mêmes conditions que les moyens de liaison selon l'art antérieur, mais plus simples et plus compacts et dans lesquels le levier-came peut être rabattu contre la tige en position de marche ou de repos.The object of the present invention is to provide connection means satisfying the same conditions as the connection means according to the prior art, but simpler and more compact and in which the cam lever can be folded against the rod in the operating position. or rest.

La chaussure selon l'invention est caractérisée par le fait que ledit levier-came est articulé dans une rainure longitudinale d'un axe rotatif traversant la tige sensiblement perpendiculairement et solidaire, en rotation, d'un excentrique coopérant avec un logement prévu sur l'une des parties de la chaussure, l'extrémité intérieure dudit axe rotatif pénétrant dans un logement prévu sur la partie inférieure de la chaussure, de manière à verrouiller la tige sur la partie inférieure pour une position du levier-came, ledit axe traversant en outre librement une pièce d'entraînement en rotation avec laquelle il est solidaire en rotation, cette pièce d'entraînement présentant une face d'appui transversale à l'axe et intercalée entre le levier-came et la tige, un élément élastique étant disposé entre la pièce d'entraînement et l'extrémité intérieure de l'axe rotatif pour pousser ladite extrémité en direction de la partie inférieure de la chaussure, le levier-came étant articulé sur l'axe rotatif au moyen d'un axe excentré par rapport au centre de sa partie large, de telle sorte qu'il est rabattu contre ladite face d'appui aussi bien dans sa position de verrouillage de la tige que dans sa position de libération de la tige.The shoe according to the invention is characterized in that said cam lever is articulated in a longitudinal groove of a rotary axis passing through the rod substantially perpendicularly and integral, in rotation, with an eccentric cooperating with a housing provided on the one part of the shoe, the inner end of said rotary axis penetrating into a housing provided on the lower part of the shoe, so as to lock the upper on the lower part for a position of the cam lever, said axis also freely passing through a rotary drive part with which it is integral in rotation, this drive piece having a bearing face transverse to the axis and interposed between the cam lever and the rod, an elastic element being disposed between the drive piece and the inner end of the rotary axis for pushing said end towards the lower part of the shoe, the cam lever being articulated on the rotary axis by means of an axis eccentric relative to the center of its wide part, so that it is folded against said bearing face both in its rod locking position and in its rod release position.

La pièce d'entraînement est de préférence en forme de bouton profilé et arrondi dans lequel le levier-came peut être rabattu, seule l'extrémité de ce levier-came dépassant latéralement le bouton pour permettre son actionnement.The drive part is preferably in the form of a rounded and profiled button in which the cam lever can be folded down, only the end of this cam lever projecting laterally from the button to allow its actuation.

L'excentrique peut être en forme de came ou simplement de forme polygonale. Quant au logement avec lequel coopére l'excentrique, il peut être simplement constitué par une plaquette métallique présentant deux rebords transversaux parallèles.The eccentric can be cam-shaped or simply polygonal. As for the housing with which the eccentric cooperates, it may simply consist of a metal plate having two parallel transverse edges.

Les moyens de liaison selon l'invention sont particulièrement simples et compacts.The connection means according to the invention are particularly simple and compact.

Le dessin annexé représente, à titre d'exemple, deux formes d'exécution de l'invention.The accompanying drawing shows, by way of example, two embodiments of the invention.

La figure 1 est une vue en perspective arrière de la chaussure valable pour les deux formes d'exécution.Figure 1 is a rear perspective view of the shoe valid for both embodiments.

La figure 2 est est une vue en coupe selon II-II de la figure 1 montrant partiellement l'arrière de la chaussure en position verrouillée de la tige sur la partie inférieure de la chaussure, selon la première forme d'exécution.Figure 2 is a sectional view along II-II of Figure 1 partially showing the rear of the shoe in the locked position of the upper on the lower part of the shoe, according to the first embodiment.

La figure 3 est une vue de dos de la chaussure, selon la première forme d'exécution, dans laquelle la tige a été arrachée à l'endroit des moyens de liaison de la tige à la partie inférieure de la chaussure.Figure 3 is a back view of the shoe, according to the first embodiment, in which the upper has been torn off at the location of the means for connecting the upper to the lower part of the shoe.

La figure 4 est une vue analogue à celle de la figure 2, mais représentant la tige libérée de la partie inférieure de la chaussure.Figure 4 is a view similar to that of Figure 2, but showing the rod released from the lower part of the shoe.

La figure 5 est une vue analogue à celle de la figure 4 montrant les moyens de liaison dans une autre position angulaire.Figure 5 is a view similar to that of Figure 4 showing the connecting means in another angular position.

La figure 6 est un arraché de la figure 1 montrant la seconde forme d'exécution des moyens de liaison.Figure 6 is a broken away from Figure 1 showing the second embodiment of the connecting means.

La figure 7 est une vue en coupe axiale des moyens représentés à la figure 6.FIG. 7 is a view in axial section of the means represented in FIG. 6.

On se réfère tout d'abord à la figure 1. La chaussure partiellement représentée est une chaussure à coque de conception connue. Elle comprend une partie inférieure ou bas de coque 1 et une tige 2 articulée sur le bas de coque 1 en deux points 3 et 4. Dans l'exécution représentée la tige 2 est en principe en une seule pièce et elle vient se fermer à l'avant par un rabat et deux boucles 5 et 6. Le basculement en arrière de la tige 2 est limité par une saillie 7 du bas de coque 1. Le dos de la tige 2 présente une partie sensiblement plane 8 coopérant avec la saillie 7 et au bas de laquelle sont montés des moyens de liaison 9 entre la tige et le bas de coque 1.We first refer to Figure 1. The shoe partially shown is a shoe shell of known design. It comprises a lower or lower part of the shell 1 and a rod 2 articulated on the lower shell 1 at two points 3 and 4. In the embodiment shown, the rod 2 is in principle in one piece and it comes to close at the front by a flap and two loops 5 and 6. The tilting back of the rod 2 is limited by a projection 7 from the bottom of the shell 1. The back of the rod 2 has a substantially flat part 8 cooperating with the projection 7 and at the bottom of which are mounted connecting means 9 between the rod and the bottom of the shell 1.

Selon une première forme d'exécution, représentée aux figures 2 et 3, ces moyens de liaison 9 sont constitués d'un excentrique 10 solidaire de la tige 2 et coopérant avec un logement 11 solidaire du bas de coque 1 (fig. 2 et 3). L'excentrique 10 est solidaire d'un moyeu cylindrique 12 lui-même solidaire d'un axe 13 traversant le dos 8 de la tige à travers une cuvette métallique 14 insérée dans un trou de la matière synthétique du dos 8 de la tige. La partie extérieure de l'axe 13 pénètre dans un bouton de commande circulaire 15 présentant une rainure diamétrale 16. Dans cette rainure 16 l'axe 13 présente une prolongement de section rectangulaire 17 sur lequel est articulé un levier-came 18 de largeur correspondante à la largeur de la rainure 16 et articulé sur la partie plate 17 au moyen d'un axe 19 fortement excentré par rapport au centre de la partie large du levier-came 18. La rainure diamétrale 16 est formée entre deux nervures arrondies 21 et 22 formant prise pour l'utilisateur pour l'entraînement du bouton 15 en rotation et présentant des lumières 20 pour le passage de l'axe 19. En position rabattue du levier-came 18, seule son extrémité 18a fait légèrement saillie hors de la rainure 16. Dans la cuvette métallique 14, facultative, est monté un ressort hélicoïdal 23 travaillant en compression et plaquant par conséquent le levier-came 18 contre le fond de la rainure 16 du bouton de commande. Dans la forme d'exécution représentée l'excentrique 10 est de forme carrée (figure 3) et l'axe géométrique de l'axe 13 intercepte l'un des axes de symétrie du carré, de telle sorte que l'excentrique 10 peut prendre trois positions déterminées stables relativement au logement 11. Ce logement 11 est constitué simplement par une plaquette métallique munie de deux rebords 24 et 25, le rebord supérieur 24 ayant une hauteur sensiblement égale à l'épaisseur de l'excentrique 10, tandis que le rebord inférieur 25 est plus haut.According to a first embodiment, shown in Figures 2 and 3, these connecting means 9 consist of an eccentric 10 secured to the rod 2 and cooperating with a housing 11 secured to the bottom of the shell 1 (fig. 2 and 3 ). The eccentric 10 is integral with a cylindrical hub 12 itself integral with an axis 13 passing through the back 8 of the rod through a metal bowl 14 inserted into a hole in the synthetic material of the back 8 of the rod. The outer part of the axis 13 enters a circular control button 15 having a diametrical groove 16. In this groove 16 the axis 13 has an extension of rectangular section 17 on which is articulated a cam lever 18 of width corresponding to the width of the groove 16 and articulated on the flat part 17 by means of an axis 19 strongly eccentric relative to the center of the wide part of the cam lever 18. The diametrical groove 16 is formed between two rounded ribs 21 and 22 forming taken for the user for driving the button 15 in rotation and having slots 20 for the passage of the axis 19. In the folded position of the cam lever 18, only its end 18a protrudes slightly out of the groove 16. In the metal bowl 14, optional, is mounted a helical spring 23 working in compression and consequently pressing the cam lever 18 against the bottom of the groove 16 of the control button. In the embodiment shown the eccentric 10 is square (Figure 3) and the geometric axis of the axis 13 intercepts one of the axes of symmetry of the square, so that the eccentric 10 can take three determined stable positions relative to the housing 11. This housing 11 is constituted simply by a metal plate provided with two flanges 24 and 25, the upper flange 24 having a height substantially equal to the thickness of the eccentric 10, while the lower edge 25 is higher.

Le moyen de liaison 9 permet simultanément de libérer la tige 2, en lui autorisant une oscillation limitée sur le bas de coque 1, et de régler l'inclinaison de la tige 2 en position bloquée de celle-ci sur le bas de coque 1. Ces fonctions seront exposées en relation avec les figures 2, 4 et 5.The connecting means 9 simultaneously makes it possible to release the rod 2, allowing it a limited oscillation on the bottom of the shell 1, and to adjust the inclination of the rod 2 in the locked position of the latter on the bottom of the shell 1. These functions will be explained in relation to Figures 2, 4 and 5.

Lorsque le levier-came 18 est dans la position représentée à la figure 2, son axe 19 étant proche du dos 8 de la tige, l'excentrique 10 est engagé dans le logement 11, entre les rebords 24 et 25. La tige 2 est alors immobilisée en rotation sur le bas de coque 1. Dans la position représentée à la figure 2, l'inclinaison de la tige est minimale.When the cam lever 18 is in the position shown in FIG. 2, its axis 19 being close to the back 8 of the rod, the eccentric 10 is engaged in the housing 11, between the flanges 24 and 25. The rod 2 is then immobilized in rotation on the shell bottom 1. In the position shown in FIG. 2, the inclination of the rod is minimal.

Pour libérer la tige du bas de coque 1, il suffit de faire tourner le levier-came 18 autour de son axe 19 de 180° dans le sens de la flèche F1 (figure 4), le levier-came 18 étant à nouveau rabattu et presque totalement escamoté dans le bouton 15. L'effet de came du levier-came 18 a pour effet de tirer sur l'axe 13 dans le sens de la flèche F2 en comprimant le ressort 23. L'excentrique 10 est alors libéré du rebord 24 du logement 11, ce qui permet à la tige de pivoter autour de son articulation sur le bas de coque 1, notamment pour permettre la marche.To release the rod from the bottom of the shell 1, it suffices to rotate the cam lever 18 around its axis 19 by 180 ° in the direction of the arrow F1 (FIG. 4), the cam lever 18 being folded down again and almost completely retracted in the button 15. The cam effect of the cam lever 18 has the effect of pulling on the axis 13 in the direction of the arrow F2 by compressing the spring 23. The eccentric 10 is then released from the flange 24 of the housing 11, which allows the rod to pivot around its articulation on the bottom of the shell 1, in particular to allow walking.

Dans la position représentée à la figure 4, il est également possible d'entraîner le bouton 15 en rotation, comme représenté à la figure 5, c'est-à-dire de modifier la position de l'excentrique 10. Dans le cas particulier on effectue une rotation de 90° ou 180°, dans un sens ou dans l'autre. Il suffit ensuite de ramener le levier-came 18 dans la position représentée à la figure 2 pour engager à nouveau l'excentrique 10 dans le logement 11. La tige 2 est alors à nouveau verrouillée, dans une autre inclinaison.In the position shown in Figure 4, it is also possible to drive the button 15 in rotation, as shown in Figure 5, that is to say to change the position of the eccentric 10. In the particular case one rotates 90 ° or 180 °, in one direction or the other. Then just bring it back the cam lever 18 in the position shown in Figure 2 to engage the eccentric 10 again in the housing 11. The rod 2 is then again locked, in another inclination.

Le moyeu 12 assure le guidage de l'axe 13 dans la cuvette 14.The hub 12 guides the axis 13 in the bowl 14.

L'excentrique 10 peut présenter de nombreuses formes, en particulier circulaires ou polygonales.The eccentric 10 can have many shapes, in particular circular or polygonal.

Selon une variante d'exécution, la butée 7 pourrait être supprimée et le rebord 25 de la plaque 11 pourrait être de même hauteur que le rebord 24. Dans la position représentée à la figure 5 l'excentrique pourrait alors passer par dessus le rebord 25 et la tige 2 de la chaussure pourrait être redressée.According to an alternative embodiment, the stop 7 could be eliminated and the flange 25 of the plate 11 could be of the same height as the flange 24. In the position shown in FIG. 5 the eccentric could then pass over the flange 25 and the upper 2 of the shoe could be straightened.

La seconde forme d'exécution, représentée à la figure 6, utilise le même bouton de commande 15 et le même levier-came 18 que la première forme d'exécution. Le levier-came 18 est solidaire d'un axe 26, correspondant à l'axe 13 de la première forme d'exécution, cet axe 26 présentant, sur une partie de sa longueur, une section non circulaire allant en s'amincissant pour former la partie 17 solidaire du bouton de commandée 15. L'extrémité intérieure de l'axe 26 est terminée par une tête circulaire 27 destinée à pénétrer avec un léger jeu dans une découpe oblongue 28 d'une plaquette 29 fixée sur la partie inférieure de la chaussure 1, transversalement au dos 8 de la tige. L'axe 26 est en outre entouré d'un corps de révolution 30 solidarisé en rotation de l'axe 26 par une nervure 31. Ce corps de révolution 30 présente une partie cylindrique excentrique 32 engagée rotativement dans une douille 33 fixée dans le dos 8 de la tige de la chaussure. L'extrémité intérieure de ce corps de révolution 30 est terminée par une partie carrée 34 centrée sur l'axe et dont un côté vient s'appuyer contre un rebord inférieur coudé 35 de la plaquette 29. L'axe 26 est entouré d'un ressort hélicoïdal 36 guidé radialement par une partie cylindrique 37 de l'axe 26 et travaillant en compression entre la tête 27 de l'axe 26 et le fond du corps de révolution 30. Le corps de révolution 30 vient en outre s'appuyer contre l'extrémité intérieure de la douille 33 par une portée 38.The second embodiment, shown in Figure 6, uses the same control button 15 and the same cam lever 18 as the first embodiment. The cam lever 18 is integral with an axis 26, corresponding to the axis 13 of the first embodiment, this axis 26 having, over part of its length, a non-circular section that tapers to form the part 17 integral with the control button 15. The inner end of the axis 26 is terminated by a circular head 27 intended to penetrate with a slight play in an oblong cutout 28 of a plate 29 fixed on the lower part of the shoe 1, transverse to the back 8 of the upper. The axis 26 is also surrounded by a body of revolution 30 secured in rotation to the axis 26 by a rib 31. This body of revolution 30 has an eccentric cylindrical part 32 rotatably engaged in a socket 33 fixed in the back 8 of the upper of the shoe. The inner end of this body of revolution 30 is terminated by a square part 34 centered on the axis and one side of which abuts against a bent lower edge 35 of the plate 29. The axis 26 is surrounded by a helical spring 36 guided radially by a cylindrical part 37 of the axis 26 and working in compression between the head 27 of the axis 26 and the bottom of the body of revolution 30. The body of revolution 30 also comes to bear against the interior end of the socket 33 by a bearing 38.

Dans l'une des position du levier-came 18, la tête 27 de l'axe 26 est engagée dans la découpe 28 de la plaque 29 et la tige de la chaussure est bloquée sur la partie inférieure. Dans l'autre position du levier-came 18, la tête 27 n'est par contre pas engagée dans la découpe 28, de telle sorte que la tige peut pivoter.In one of the position of the cam lever 18, the head 27 of the axis 26 is engaged in the cutout 28 of the plate 29 and the upper of the shoe is blocked on the lower part. In the other position of the cam lever 18, the head 27 is however not engaged in the cutout 28, so that the rod can pivot.

Le réglage de l'inclinaison de la tige se fait par la rotation du bouton 15. La variation de l'inclinaison est assurée par la partie excentrique 32. La partie carrée 34 a pour seul effet de déterminer des positions discrètes en venant s'appuyer par l'un de ses côtés contre le rebord 35 de la plaquette 29. Cette partie carrée peut être supprimée si l'on désire un réglage en continu. Dans ce cas il conviendrait de freiner la rotation de l'excentrique par un montage à frottement gras ou par tout autre moyen.The inclination of the rod is adjusted by the rotation of the knob 15. The variation of the inclination is ensured by the eccentric part 32. The square part 34 has the sole effect of determining discrete positions by coming to bear by one of its sides against the rim 35 of the plate 29. This square part can be omitted if one wishes a continuous adjustment. In this case, the rotation of the eccentric should be slowed down by a greasy friction assembly or by any other means.

Les formes d'exécution décrites sont, bien entendu, susceptibles de nombreuses variantes sans sortir du cadre de l'invention. En particulier, la pièce 11 de la figure 2 pourrait être supprimée et remplacée par une creusure formée directement dans le matériau de la coque 1. De même, dans l'exécution selon les figures 6 et 7, la pièce 29 pourrait être supprimée et la butée 35 et la rainure 28 pourraient être formées directement dans la matière de la coque.The embodiments described are, of course, susceptible of numerous variants without departing from the scope of the invention. In particular, the part 11 of FIG. 2 could be omitted and replaced by a recess formed directly in the material of the shell 1. Similarly, in the embodiment according to FIGS. 6 and 7, the part 29 could be eliminated and the stop 35 and the groove 28 could be formed directly in the material of the shell.
