Description

La présente invention a pour objet un dispositif de tension d'un câble de serrage d'une chaussure de ski, comprenant une embase destinée à être fixée à la chaus­sure et portant au moins un levier-tendeur articulé sur l'embase et auquel est attaché au moins un câble par l'intermédiaire d'une pièce montée coulissante longitu­dinalement sur le levier-tendeur et susceptible d'occu­per essentiellement deux positions, l'une de serrage et l'autre de relaxation, le levier-tendeur étant muni de moyens de maintien de ladite pièce coulissante en posi­tion de serrage.The present invention relates to a device for tensioning a tightening cable of a ski boot, comprising a base intended to be fixed to the boot and carrying at least one tensioning lever articulated on the base and to which is attached at least one cable by means of a piece mounted to slide longitudinally on the tensioning lever and capable of occupying essentially two positions, one for tightening and the other for relaxation, the tensioning lever being provided with means for maintaining said sliding part in the clamping position.

Un dispositif de ce type est connu du document EP-A-0 300 955. Dans ce dispositif, les moyens de main­tien de la pièce coulissante en position de serrage sont constitués par un levier auxiliaire articulé, soit sur le dos du levier-tendeur soit, à son extrémité. Dans le cas où le levier auxiliaire est articulé sur le dos du levier-tendeur, il actionne la pièce coulissante par un doigt excentrique en prise avec la pièce coulis­sante. Dans le cas où il est articulé à l'extrémité du levier-tendeur, le levier auxiliaire présente une par­tie excentrique en forme de came s'appuyant sur l'ex­trémité du levier-tendeur et par laquelle le levier auxiliaire tire la pièce coulissante. Dans les deux cas la relaxation du ou des câbles est relativement faible et une augmentation importante de la relaxation n'est constructivement pas possible. En outre, le levier auxiliaire forme une saillie relativement importante lorsqu'il est en position de relaxation.A device of this type is known from document EP-A-0 300 955. In this device, the means for holding the sliding part in the clamping position consist of an articulated auxiliary lever, either on the back of the tensioning lever or , at its end. In the case where the auxiliary lever is articulated on the back of the tensioning lever, it actuates the sliding part by an eccentric finger engaged with the sliding part. In the case where it is articulated at the end of the tensioning lever, the auxiliary lever has an eccentric part in the shape of a cam resting on the end of the tensioning lever and by which the auxiliary lever pulls the sliding part. In both cases the relaxation of the cable (s) is relatively weak and a significant increase in relaxation is not constructively possible. In addition, the auxiliary lever forms a relatively large projection when it is in the relaxed position.

La présente invention a principalement pour but d'obte­nir une relaxation instantanée et importante, notamment pour permettre la marche dans le cas où le dispositif de tension est utilisé pour le serrage d'une tige de chaussure en deux parties.The main object of the present invention is to obtain instantaneous and significant relaxation, in particular to allow walking in the case where the tensioning device is used for tightening a shoe upper in two parts.

Le dispositif de tension selon l'invention est caracté­risé par le fait que les moyens de maintien de la pièce coulissante sont constitués par une butée rétractable.The tensioning device according to the invention is characterized in that the means for holding the sliding piece consist of a retractable stop.

Lorsque la butée est rétractée, la pièce coulissante est libérée, de telle sorte que l'on peut obtenir ins­tanément une grande relaxation.When the stopper is retracted, the sliding part is released, so that great relaxation can be obtained instantly.

La butée rétractable peut être montée élastiquement de telle sorte qu'elle revient automatiquement dans sa position de verrouillage.The retractable stop can be resiliently mounted so that it automatically returns to its locked position.

Les moyens de commande de la butée rétractable peuvent être réalisés en des dimensions réduites, de telle sorte qu'ils ne constituent pas de protubérance ou de saillie gênante.The control means of the retractable stop can be made in reduced dimensions, so that they do not constitute a protrusion or annoying projection.

Le dispositif de tension représenté aux figures 1 à 3 comprend une embase 1 destinée à être fixée sur une chaussure, embase munie d'un étrier 2 sur lequel est articulé, autour d'un axe 3, un levier-tendeur 4 cons­titué d'une pièce profilée en U. L'intérieur de ce levier-tendeur 4 présente une glissière 5 dans laquelle est montée une plaque coulissante 6 munie d'une denture 7, en dents de scie, faisant saillie entre les bords latéraux intérieurs de la coulisse 5. La plaque dentée 6 présente en outre, à son extrémité inférieure, une saillie 8 pour son entraînement manuel comme ceci sera décrit plus loin. Entre les côtés latéraux parallèles du levier-tendeur 4 est monté un cliquet 9 articulé au­tour d'un axe 10 traversant les côtés du levier-tendeur 4 par deux fentes parallèles 11 et 12. Aux extrémités coudées 10a et 10b de l'axe 10 sont fixées les extrémi­tés d'un ou deux câbles 13. Le bec du cliquet 9 est en­gagé entre deux dents de la denture 7 de la plaque cou­lissante 6. Un ressort en cor de chasse (non représenté) maintient le cliquet dans la denture 7. L'extrémité in­férieure de la glissière 5 présente un rétrécissement 14 constituant une butée destinée à limiter la course de la plaque dentée 6.The tensioning device shown in Figures 1 to 3 comprises a base 1 intended to be fixed on a shoe, base provided with a stirrup 2 on which is articulated, around an axis 3, a tensioning lever 4 consisting of a U-shaped part. The interior of this tensioning lever 4 has a slide 5 in which is mounted a sliding plate 6 provided with teeth 7, sawtooth, projecting between the edges inner side of the slide 5. The toothed plate 6 further has, at its lower end, a projection 8 for its manual drive as will be described later. Between the parallel lateral sides of the tensioning lever 4 is mounted a pawl 9 articulated around an axis 10 passing through the sides of the tensioning lever 4 by two parallel slots 11 and 12. At the bent ends 10a and 10b of the axis 10 are fixed the ends of one or two cables 13. The spout of the pawl 9 is engaged between two teeth of the toothing 7 of the sliding plate 6. A hunting horn spring (not shown) keeps the pawl in the toothing 7. L the lower end of the slide 5 has a narrowing 14 constituting a stop intended to limit the stroke of the toothed plate 6.

Aux figures 1 et 2, la plaque dentée 6 est retenue, contre la traction des câbles 13, par une butée rétrac­table constituée par l'extrémité rectangulaire 15 d'un doigt cylindrique 16, sur lequel est articulé, autour d'un axe 17, un petit levier 18 dont les ailes 18a, situées de chaque côté du doigt 16, sont excentriques relativement à l'axe 17. Le doigt 16 est monté dans une douille 19 fixée au levier tendeur 4 et dans laquelle est logé un ressort 20 travaillant en compression entre le fond de la douille 19 et la partie rectangulaire 15 du doigt 16.In FIGS. 1 and 2, the toothed plate 6 is retained, against the traction of the cables 13, by a retractable stop constituted by the rectangular end 15 of a cylindrical finger 16, on which is articulated, around an axis 17, a small lever 18 whose wings 18a, located on each side of the finger 16, are eccentric relative to the axis 17. The finger 16 is mounted in a socket 19 fixed to the tensioning lever 4 and in which is housed a spring 20 working in compression between the bottom of the sleeve 19 and the rectangular part 15 of the finger 16.

Pour libérer la plaque dentée 6, c'est-à-dire relâcher le câble 13, il suffit de basculer vers le bas le petit levier 18, dans le sens de la flèche F1. L'excentricité du levier 18 a pour effet de rétracter le doigt 16, de telle sorte que la plaque dentée 6 peut descendre jus­qu'à ce qu'elle arrive en butée contre la butée 14. Le levier 18 occupe la position représentée à la figure 4. Cette position est stable. On remarque que le levier-­tendeur 4 est resté fermé. Pour revenir en position serrée on relève le levier 18 dans le sens de la flèche F2, pour le ramener dans la position représentée à la figure 1. On ouvre ensuite le levier-tendeur 4, puis on repousse la plaque dentée 6 par sa saillie 8 au-delà du doigt de verrouillage 16, lequel, sous la poussée de son ressort 20 revient dans la position de la figure 1. On peut alors refermer le levier 4 pour se retrouver dans la position de serrage représentée à la figure 1. On remarquera que le réglage du serrage a été conservé lors de ces opérations.To release the toothed plate 6, that is to say release the cable 13, it suffices to tilt the small lever 18 downwards, in the direction of the arrow F1. The eccentricity of the lever 18 has the effect of retracting the finger 16, so that the toothed plate 6 can descend until it comes into abutment against the stop 14. The lever 18 occupies the position shown in the figure 4. This position is stable. Note that the tensioner lever 4 has remained closed. To return to the clamped position, the lever 18 is raised in the direction of the arrow F2, to bring it back to the position shown in FIG. 1. The tensioner lever 4 is then opened, then the toothed plate 6 is pushed back by its projection 8 beyond the locking finger 16, which, under the thrust of its spring 20 returns to the position of Figure 1. We can then close the lever 4 to be in the clamping position shown in Figure 1. It will be noted that the tightening adjustment was kept during these operations.

Les figures 1 et 4 montrent un second levier-tendeur 21 articulé autour d'un axe 22 sur un second étrier 23 de l'embase 1, au-dessous du levier-tendeur 4 et aligné sur celui-ci. Ce second levier-tendeur 21 est destiné au serrage d'une autre partie de la chaussure, comme ceci sera décrit plus loin en relation avec les figures 9 et 10.Figures 1 and 4 show a second tensioner lever 21 articulated around an axis 22 on a second stirrup 23 of the base 1, below the tensioner lever 4 and aligned thereon. This second tensioning lever 21 is intended for tightening another part of the shoe, as will be described later in relation to FIGS. 9 and 10.

La butée rétractable 15 pourrait être exécutée de nom­breuses autres manières. Un exemple est représenté aux figures 5 et 6. La butée rétractable présente une tête rectangulaire 15′ identique à la tête 15 de la figure 1. Cette tête 15′ est solidaire d'une tige cylindrique 24 munie d'une nervure hélicoïdale à forte pente coopé­rant avec une rainure hélicoïdale prévue dans un bouton 25 monté rotativement sur le levier 4. Ce bouton 25 présente une creusure dans laquelle est logé un ressort travaillant en compression entre le fond de cette creu­sure et la butée rétractable 15′. Celle-ci est retenue dans le bouton par une portée annulaire 27. Pour rela­cher la tension sur le câble 13, il suffit de tourner le bouton 25, ce qui a pour effet de rétracter la butée 15′. Pour revenir en position de serrage, on ouvre le levier-tendeur 4, comme décrit précédemment, et l'on repousse la plaque dentée 6. La butée 15 revient alors automatiquement dans la position représentée à la figu­re 5 sous l'effet du ressort 26 dont la force est suf­fisante pour entraîner le bouton 25 en rotation, rota­tion qui est d'autre part possible en raison de la for­te pente de sa rainure hélicoïdale.The retractable stop 15 could be performed in many other ways. An example is shown in Figures 5 and 6. The retractable stop has a rectangular head 15 ′ identical to the head 15 of Figure 1. This head 15 ′ is integral with a cylindrical rod 24 provided with a steep helical rib cooperating with a helical groove provided in a button 25 rotatably mounted on the lever 4. This button 25 has a recess in which is housed a spring working in compression between the bottom of this recess and the retractable stop 15 ′. This is retained in the button by an annular bearing 27. To release the tension on the cable 13, simply turn the button 25, which has the effect of retracting the stop 15 ′. To return to the tightening position, the tensioning lever 4 is opened, as described above, and the toothed plate 6 is pushed back. The stop 15 then automatically returns to the position shown in FIG. 5 under the effect of the spring 26 the force of which is sufficient to drive the button 25 in rotation, a rotation which is on the other hand possible due to the steep slope of its helical groove.

Le ou les câbles pourraient être reliés par tout autre moyen réglable à la plaque coulissante 6. Une variante d'exécution est représentée, à titre d'exemple, aux figures 7 et 8. La plaque coulissante 6′ est munie d'une portée 28 sur laquelle s'appuie la tête 29 d'une tige filetée 30 parallèle au levier 4 et sur laquelle est engagé un écrou rectangulaire 31, non rotatif, auquel sont fixées les extrémités d'un ou deux câbles 13. La vis 30 est en outre retenue axialement par un circlips 32. La rotation de la vis 30 a pour effet de déplacer axialement l'écrou 31 et par conséquent de régler la tension sur les câbles.The cable or cables could be connected by any other adjustable means to the sliding plate 6. An alternative embodiment is shown, for example, in FIGS. 7 and 8. The sliding plate 6 ′ is provided with a bearing 28 on which rests the head 29 of a threaded rod 30 parallel to the lever 4 and on which is engaged a rectangular nut 31, not rotatable, to which are fixed the ends of one or two cables 13. The screw 30 is further retained axially by a circlip 32. The rotation of the screw 30 has the effect of axially displacing the nut 31 and consequently of adjusting the tension on the cables.

Un exemple d'utilisation des dispositifs de tension décrits est représenté aux figures 9 et 10. Le disposi­tif de tension représenté à la figure 1 est monté sur la demi-tige postérieure 32 d'une chaussure de ski 33 à entrée par l'arrière, cette demi-tige postérieure 32 étant articulée sur la coque de la chaussure autour d'un axe 34. Le levier-tendeur 4 agit sur un câble 13 fermant, de manière connue en soi, les deux parties 32 et 35 de la tige de la chaussure. Le levier-tendeur 21 agit quant à lui sur deux câbles 36 et 37 serrant le pied de manière connue. Dans la position représentée à la figure 9, la chaussure est fermée et serrée.An example of use of the tensioning devices described is shown in FIGS. 9 and 10. The tensioning device shown in FIG. 1 is mounted on the rear half-upper 32 of a ski boot 33 with rear entry, this rear half-rod 32 being articulated on the shell of the shoe around an axis 34. The tensioning lever 4 acts on a cable 13 closing, in a manner known per se, the two parts 32 and 35 of the rod of the shoe. The tensioning lever 21 acts in turn on two cables 36 and 37 clamping the foot in a known manner. In the position shown in Figure 9, the shoe is closed and tight.

Par l'abaissement du levier auxiliaire 18 on passe ins­tantanément en position de relaxation, telle que repré­sentée à la figure 4. La tension sur le câble 13 est largement relâchée, de telle sorte que la cheville est partiellement libérée, ce qui permet à la jambe de se redresser comme représenté à la figure 10. Le skieur peut ainsi marcher, le pied restant par ailleurs tenu, car la tension exercée par le levier 21 est maintenue. Pour revenir dans la position serrée représentée à la figure 9, il suffit d'ouvrir le levier-tendeur 4, qui bascule par dessus le levier tendeur 21, de relever le levier auxiliaire 18 et de repousser la plaque dentée 6, comme décrit précédemment, puis de refermer le levier-tendeur 4.By lowering the auxiliary lever 18, one instantly goes into the relaxation position, as shown in FIG. 4. The tension on the cable 13 is largely released, so that the ankle is partially released, which allows the leg to straighten up as shown in Figure 10. The skier can walk, the foot remaining also held, because the tension exerted by the lever 21 is maintained. To return to the tight position shown in FIG. 9, it suffices to open the tensioning lever 4, which switches over the tensioning lever 21, to raise the auxiliary lever 18 and to push back the toothed plate 6, as described above, then close the tensioning lever 4.

Le dispositif de tension selon l'invention pourrait bien entendu être également utilisé pour le serrage du pied. Le dispositif de tension pourrait être monté en un autre endroit de la chaussure. L'embase pourrait porter deux leviers-tendeurs l'un à côté de l'autre.The tensioning device according to the invention could of course also be used for tightening the foot. The tensioning device could be mounted elsewhere on the shoe. The base could carry two tensioning levers next to each other.
