Abstract

This ski boot fastener comprises a stretching lever having pivotally mounted therein at least two nipples each fulcrumed on a crosspin, and boot closing cables having each one end passing through the corresponding nipple and anchored to a cable head or socket movable along the cable and reacting against the corresponding nipple. The head or socket consists of an internally screw-threaded tube engaged by an externally screw-threaded core soldered to the cable end. The adjustment is obtained by rotating the socket.

Description

L'invention a pour objet un dispositif de fermeture de deux parties d'une chaussure de sport notamment une chaussure de ski, constituée de moyens tendeur solidaires de l'une des parties de la chaussure et agissant sur des câbles fixés par une de leurs extrémités à l'autre partie de la chaussure.The invention relates to a device for closing two parts of a sports boot, in particular a ski boot, consisting of tensioning means secured to one of the parts of the boot and acting on cables fixed by one of their ends. to the other part of the shoe.

Une chaussure comportant un dispositif de ce type et une chaussure de ski conforme au préambule de la revendication 10 sont décrite dans le brevet US-3.570.148. Dans cette chaussure, chaque câble est attaché par ses deux extrémités à l'oreille supérieure de la chaussure et forme une boucle relativement courte qui passe dans le cran d'un levier-tendeur monté sur le côté de la chaussure et pivotant dans le plan de symétrie de la boucle. Le levier-tendeur étant dirigé vers le bas, sa longueur est limitée par la hauteur de la chaussure dans la région du pied. Il faut donc fournir un effort considérable pour bien serrer la chaussure, d'autant plus que le câble agit en deux endroits simultanément. Le levier agit en outre avec la même force sur les deux points de serrage, alors que l'utilisateur désirerait parfois différencier la pression de serrage aux deux points d'attache du câble. Enfin, le réglage fin de la longueur du câble, c'est-à-dire de la force de serrage, s'effectue par des écrous aux points de fixation des extrémités du câble.A boot comprising a device of this type and a ski boot conforming to the preamble of claim 10 are described in patent US-3,570,148. In this shoe, each cable is attached by its two ends to the upper ear of the shoe and forms a relatively short loop which passes through the notch of a tensioning lever mounted on the side of the shoe and pivoting in the plane of symmetry of the loop. The tensioning lever being directed downwards, its length is limited by the height of the shoe in the region of the foot. It is therefore necessary to make a considerable effort to properly tighten the shoe, especially since the cable acts in two places simultaneously. The lever also acts with the same force on the two clamping points, while the user would sometimes wish to differentiate the clamping pressure at the two cable attachment points. Finally, the fine adjustment of the cable length, that is to say the clamping force, is carried out by nuts at the fixing points of the ends of the cable.

Dans une autre exécution (CH-A-406.901) les extrémités du câble sont fixées à la même partie de la coque que le levier-tendeur, le câble formant trois boucles dont deux passent sur des crochets solidaires de l'autre partie de la chaussure. Cette chaussure présente les mêmes inconvénients que la chaussure précédente.In another embodiment (CH-A-406.901) the ends of the cable are fixed to the same part of the shell as the tensioning lever, the cable forming three loops, two of which pass over hooks integral with the other part of the shoe . This shoe has the same drawbacks as the previous shoe.

La présente invention a pour but de réaliser un dispositif de fermeture à câbles susceptible d'être fermé avec un effort réduit et dans lequel les forces de serrage peuvent être réglées individuellement pour chaque point d'attache des câbles. La réduction de l'effort nécessaire pour la tension de chaque câble doit en outre permettre la tension simultanée de plusieurs câbles par l'actionnement d'un seul levier, c'est-à-dire par une seule opération.The object of the present invention is to provide a cable closure device capable of being closed with reduced force and in which the clamping forces can be adjusted individually for each cable attachment point. The reduction of the effort required for the tension of each cable must also allow the simultaneous tension of several cables by the actuation of a single lever, that is to say by a single operation.

A cet effet le dispositif de fermeture selon l'invention présente les caractéristiques définies par la revendication 1. Des modes particuliers de réalisation de l'invention apparaissent dans les revendications dépendantes 2 à 9.To this end, the closure device according to the invention has the characteristics defined by claim 1. Particular embodiments of the invention appear in dependent claims 2 to 9.

Les extrémités de câbles étant attachées de façon indépendante au levier-tendeur, les distances de ces points d'attache à l'axe d'articulation du levier peuvent être différentes, d'où une action différenciée sur les câbles et il est en outre possible de régler individuellement cette tension.The cable ends being independently attached to the tensioning lever, the distances from these points of attachment to the axis of articulation of the lever can be different, hence a differentiated action on the cables and it is also possible to adjust this tension individually.

Le levier peut être divisé en deux leviers parallèles actionnables indépendamment l'un de l'autre dans un certain ordre, l'un des leviers étant muni d'une oreille qui entraîne simultanément l'autre levier lors de sa fermeture. Selon ce principe, le levier pourrait être triple, quadruple, etc. Le levier double augmente encore les possibilités d'ajustage du serrage à la convenance du skieur.The lever can be divided into two parallel levers which can be actuated independently of one another in a certain order, one of the levers being provided with an ear which simultaneously drives the other lever when it is closed. According to this principle, the lever could be triple, quadruple, etc. The double lever further increases the possibilities of adjusting the tightness to suit the skier.

L'invention a également pour objet une chaussure de ski équipée d'un dispositif de fermeture conforme à la revendication 1.The invention also relates to a ski boot equipped with a closure device according to claim 1.

La chaussure de ski représentée à la figure 1 est constituée, de manière connue en soit, d'une coque 1 en matière synthétique formant la semelle et entourant le pied et le talon et sur laquelle est articulée une tige ou manchette 2 se fermant à l'avant au moyen d'une boucle 3. La coque 1 et la tige 2 abritent une garniture ou chausson intérieur 4. Le dessus de la coque 1, sur le pied, est formé de deux oreilles 5 et 6 se recouvrant mutuellement pour assurer une bonne fermeture de la coque et pour permettre le serrage du pied. Les moyens de fermeture des oreilles 5 et 6 et de serrage du pied sont constitués d'un levier-tendeur 7 articulé sur la tige 2, ce levier agissant sur deux câbles de traction 8 et 9 guidés dans des guidages 10 et 11 pratiqués dans une suré- paisseur 12 de la coque et dont les extrémités sont fixées à l'oreille supérieure 5 au moyen de plots d'ancrage 13 et respectivement 14 noyés dans la matière de l'oreille 5.The ski boot shown in Figure 1 consists, in a manner known per se, of a shell 1 of synthetic material forming the sole and surrounding the foot and the heel and on which is articulated a rod or cuff 2 closing at l 'front by means of a loop 3. The shell 1 and the rod 2 house an inner lining or liner 4. The top of the shell 1, on the foot, is formed by two ears 5 and 6 overlapping each other to ensure a good closing of the shell and to allow the tightening of the foot. The means for closing the ears 5 and 6 and for clamping the foot consist of a tensioning lever 7 articulated on the rod 2, this lever acting on two traction cables 8 and 9 guided in guides 10 and 11 practiced in a extra thickness 12 of the shell and the ends of which are fixed to the upper ear 5 by means of anchoring studs 13 and respectively 14 embedded in the material of the ear 5.

Le levier-tendeur 7 est articulé sur une plaque de base 15 fixée sur la manchette 2 au moyen d'une vis 16 constituant simultanément l'axe d'articulation de la tige 2 sur la coque 1. La plaque 15 est munie de deux joues parallèles 17 et 18 formant un étrier sur lequel est articulé le levier-tendeur 7. Celui-ci est dirigé vers l'arrière, légèrement obliquement vers le haut, approximativement parallèlement au bord inférieur de la tige 2. Le point d'articulation du levier-tendeur 7 et son orientation permettent d'avoir un levier-tendeur relativement long et dans tous les cas plus long que les boucles usuelles placées sur le côté du pied et dirigées vers la semelle, bien que le levier selon l'invention puisse être également disposé comme les boucles usuelles. Si la chaussure est munie de moyens de réglage de l'inclinaison latérale de la tige 2, tels que décrits par exemple dans le brevet CH 638 383, la plaque 15 fait avantageusement partie de ces moyens de réglage. Le levier-tendeur 7 présente deux fentes parallèles 19 et 20 débouchant sur son articulation, fentes qui permettent le passage des câbles 8 et 9 lorsqu'on relève le levier-tendeur comme représenté à la figure 4.The tensioning lever 7 is articulated on a base plate 15 fixed on the cuff 2 by means of a screw 16 simultaneously constituting the axis of articulation of the rod 2 on the shell 1. The plate 15 is provided with two cheeks parallels 17 and 18 forming a stirrup on which the tensioning lever 7 is articulated. This is directed towards the rear, slightly obliquely upwards, approximately parallel to the lower edge of the rod 2. The point of articulation of the lever tensioner 7 and its orientation make it possible to have a relatively long tension lever and in any case longer than the usual loops placed on the side of the foot and directed towards the sole, although the lever according to the invention can also be arranged like the usual loops. If the shoe is provided with means for adjusting the lateral inclination of the upper 2, as described for example in patent CH 638 383, the plate 15 advantageously forms part of these adjustment means. The tensioning lever 7 has two parallel slots 19 and 20 opening onto its articulation, slots which allow the passage of cables 8 and 9 when the tensioning lever is raised as shown in FIG. 4.

Le levier-tendeur sera décrit en détail au moyen des figures 2 à 6. Le levier-tendeur 7 présente un profil en double U (figures 4 et 6), c'est-à-dire deux ailes latérales 21, 22 et une nervure centrale 23. Les câbles 8 et 9 sont attachés au levier-tendeur 7 au moyen d'une noix 24, respectivement 25 articulée respectivement entre chacune des ailes 21 et 22 et la nervure centrale 23 au moyen d'un axe 26, respectivement 27. Ces axes 26 et 27 sont situés à des distances différentes de l'axe d'articulation 28 du levier-tendeur sur son support 15. Les câbles 8 et 9 sont retenus sur leur noix 24 et 25 au moyen d'une tête de câble 29, respectivement 30, se présentant sous la forme d'un tube taraudé à l'intérieur duquel est logé un noyau fileté 31 (figure 6) solidaire du câble 8. Le câble 9 est fixé de la même manière. La noix 24 est venue d'une pièce avec un embout cylindrique 32. La noix 24 et son embout 32 sont traversés par une fente d'élasticité 33 s'étendant de l'axe de la noix 24 à l'extrémité de l'embout 32. L'embout 32 est en outre tubulaire et communique avec un trou radial 34 à travers la noix 24 pour le passage du câble 8. L'extrémité de la pièce cylindrique 29 située du côté de la noix 24 n'est pas taraudée (figure 3), mais présente un logement cylindrique destiné à recevoir l'embout 32, l'entrée 35 de ce logement présentant un diamètre inférieur au diamètre du logement et venant s'accrocher dans une gorge 36 de l'embout 32. La pièce cylindrique 29 est fixée sur l'embout 32 par encliquetage et peut tourner sur cet embout. Elle vient s'appuyer contre une face plane de la noix 24. La tête de câble 30 est réalisée de manière identique. Le câble 8 ne pouvant pas tourner, son noyau 31 est également retenu en rotation de telle sorte que lorsqu'on tourne la pièce 29, le noyau 31 se déplace axialement à l'intérieur de la pièce 29. Il en est de même pour le câble 9. Il est ainsi possible de modifier la longueur active des câbles.The tensioner lever will be described in detail by means of Figures 2 to 6. The tensioner lever 7 has a double U profile (Figures 4 and 6), that is to say two lateral wings 21, 22 and a rib central 23. The cables 8 and 9 are attached to the tensioning lever 7 by means of a nut 24, respectively 25 articulated respectively between each of the wings 21 and 22 and the central rib 23 by means of an axis 26, respectively 27. These axes 26 and 27 are located at different distances from the articulation axis 28 of the tensioning lever on its support 15. The cables 8 and 9 are retained on their nuts 24 and 25 by means of a cable head 29 , respectively 30, in the form of a threaded tube inside which is housed a threaded core 31 (Figure 6) integral with the cable 8. The cable 9 is fixed in the same way. The nut 24 came in one piece with a cylindrical tip 32. The nut 24 and its tip 32 are crossed by an elasticity slot 33 extending from the axis of the nut 24 to the end of the tip 32. The end piece 32 is also tubular and communicates with a radial hole 34 through the nut 24 for the passage of the cable 8. The end of the cylindrical part 29 located on the side of the nut 24 is not tapped ( Figure 3), but has a cylindrical housing for receiving the tip 32, the inlet 35 of this housing having a diameter less than the diameter of the housing and coming to hang in a groove 36 of the tip 32. The cylindrical part 29 is fixed on the end piece 32 by snap-fastening and can rotate on this end piece. It comes to bear against a flat face of the nut 24. The cable head 30 is produced in an identical manner. Since the cable 8 cannot rotate, its core 31 is also kept in rotation so that when the part 29 is rotated, the core 31 moves axially inside the part 29. The same is true for the cable 9. It is thus possible to modify the active length of the cables.

Pour le chaussage, le levier 7 est écarté de la chaussure comme représenté à la figure 7. Dans cette position les têtes de câbles 27 et 30 peuvent être écartées du levier-tendeur 7 comme représenté à la figure 8. Dans cette position écartée, les têtes de câbles peuvent être facilement entraînées en rotation par leur extrémité moletée 37 pour le réglage de la longueur active des câbles. Une fois ce réglage effectué, les tête de câbles 29 et 30 sont rabattues dans le levier-tendeur 7 dans lequel elles sont maintenues par deux pattes élastiques 38, respectivement 39 découpées dans la nervure centrale 23. La longueur active des câbles se laisse donc régler individuellement pour chaque câble bien qu'on ait un seul levier-tendeur. Les distances entre chacun des axes 26 à 27 et l'axe 28 d'articulation du levier sont choisies de telle sorte que le raccourcissement du câble 8 agissant près du cou-de-pied soit sensiblement plus long que l'allongement, respectivement le raccourcissement du câble agissant près de l'extrémité du pied. Il serait bien entendu possible de multiplier les points de serrage et les câbles, en particulier d'avoir un troisième câble actionné de la même manière par le levier 7. Le réglage des têtes de câbles pourrait à la rigueur se faire sans écarter les tubes 29 et 30 du levier.For footwear, the lever 7 is moved away from the shoe as shown in FIG. 7. In this position the cable heads 27 and 30 can be moved away from the tensioning lever 7 as shown in FIG. 8. In this position removed, the cable heads can be easily rotated by their knurled end 37 for adjusting the active length of the cables. Once this adjustment has been made, the cable heads 29 and 30 are folded down in the tensioning lever 7 in which they are held by two elastic tabs 38, respectively 39 cut out in the central rib 23. The active length of the cables can therefore be adjusted individually for each cable although there is only one tensioning lever. The distances between each of the axes 26 to 27 and the axis 28 of articulation of the lever are chosen so that the shortening of the cable 8 acting near the instep is substantially longer than the elongation, respectively the shortening of the cable acting near the end of the foot. It would of course be possible to multiply the clamping points and the cables, in particular to have a third cable actuated in the same way by the lever 7. The adjustment of the cable heads could in fact be done without removing the tubes 29 and 30 of the lever.

Une seconde forme d'exécution de l'invention sera maintenant décrite au moyen des figures 9, 10 et 11. Dans sa plus grande partie la chaussure représentée à la figure 9 est identique à la chaussure représentée à la figure 1 et elle ne sera dès lors pas décrite en détail, les éléments identique étant désignés par les même références. On se contentera de décrire les différences. La différence essentielle réside dans le fait que le levier-tendeur est décomposé en deux leviers-tendeurs indépendants 40 et 41 constitués par des pièces profilées en U. Pour assurer l'articulation de ces deux leviers-tendeurs 40 et 41 sur la base 15 solidaire de la tige 2, cette base 15 est complétée par un étrier 42 soudé au milieu de la base 15 et sur lequel sont articulés au moyen d'un axe rivetés commun les ailes adjacentes des deux leviers-tendeurs 40 et 41. Les ailes extérieures des leviers-tendeurs 40 et 41 sont articulées au moyen d'axes riveté sur les joues 17 et 18 de la base 15. Les câbles 8 et 9 sont attachés aux leviers-tendeurs 40 et 41 de la même manière que dans la première forme d'exécution; le câble 8 est attaché au levier 41 par une tête de câble 29, alors que le câble 9 est attaché au levier-tendeur 40. Le levier-tendeur 41 est muni d'une oreille latérale 43 s'étendant parallèlement à la surface de ce levier-tendeur et venant s'encastrer sur une portée 44 formée à l'extrémité de l'autre levier-tendeur 40. Les leviers-tendeurs 40 et 41 peuvent dès lors être actionnés séparément, sauf lorsque les leviers-tendeurs sont solidarisés par l'oreille 43 du levier-tendeur 41. Ainsi, lors de l'ouverture des leviers-tendeurs, il est possible soit de relever successivement le levier-tendeur 41, puis le levier-tendeur 40 ou les deux leviers-tendeurs ensemble si l'on entraîne le levier-tendeur 40. Inversement, lors de la fermeture, on peut soit rabattre successivement le levier-tendeur 40 puis le levier-tendeur 41 ou simultanéement les deux leviers en agissant directement sur le levier-tendeur 41. Cette semi-indépendance des leviers-tendeurs permet d'effectuer un réglage plus fin du serrage du pied qu'en utilisant un levier-tendeur unique. Il est ainsi possible d'ajuster le serrage du pied près de son extrémité au point 14 en agissant seulement sur le tendeur 40. Un serrage satisfaisant ayant été ajusté, il est ensuite possible d'ajuster séparément le serrage au point 13, c'est-à-dire dans la région du cou-de-pied. Inversement il est possible de relâcher le serrage du cou-de-pied sans modifier le serrage au point 14. Une fois le réglage effectué les deux leviers-tendeurs peuvent être utilisés comme un levier-tendeur unique en agissant sur le levier-tendeur 41 à la fermeture et sur le levier-tendeur 40 ou sur les deux leviers-tendeurs 40 et 41 simultanément, à l'ouverture. Il serait bien entendu possible, selon le même principe, de disposer trois leviers parallèlement ou davantage.A second embodiment of the invention will now be described by means of Figures 9, 10 and 11. For the most part the shoe shown in Figure 9 is identical to the shoe shown in Figure 1 and it will not be when not described in detail, the identical elements being designated by the same references. We will just describe the differences. The essential difference lies in the fact that the tensioning lever is broken down into two independent tensioning levers 40 and 41 constituted by U-shaped parts. To ensure the articulation of these two tensioning levers 40 and 41 on the integral base 15 of the rod 2, this base 15 is completed by a stirrup 42 welded in the middle of the base 15 and on which are articulated by means of a common riveted axis the adjacent wings of the two tensioning levers 40 and 41. The outer wings of the tension levers 40 and 41 are articulated by means of pins riveted on the cheeks 17 and 18 of the base 15. The cables 8 and 9 are attached to the tension levers 40 and 41 in the same manner as in the first form of execution; the cable 8 is attached to the lever 41 by a cable head 29, while the cable 9 is attached to the tensioning lever 40. The tensioning lever 41 is provided with a lateral lug 43 extending parallel to the surface of this tensioning lever and coming to be embedded on a bearing 44 formed at the end of the other tensioning lever 40. The tensioning levers 40 and 41 can therefore be actuated separately, except when the tensioning levers are secured by the 'ear 43 of the tensioning lever 41. Thus, when opening the tensioning levers, it is possible either to raise successively the tensioning lever 41, then the tensioning lever 40 or the two tensioning levers together if the the tensioning lever 40 is driven. Conversely, during closing, the tensioning lever 40 can then be folded down successively then the tensioning lever 41 or simultaneously the two levers by acting directly on the tensioning lever 41. This semi-independence tension levers allows finer adjustment of the s foot errage only by using a single tensioning lever. It is thus possible to adjust the clamping of the foot near its end at point 14 by acting only on the tensioner 40. A satisfactory clamping having been adjusted, it is then possible to separately adjust the clamping at point 13, that is ie in the instep region. Conversely, it is possible to release the tightening of the instep without modifying the tightening at point 14. Once the adjustment has been made, the two tensioning levers can be used as a single tensioning lever by acting on the tensioning lever 41 to closing and on the tensioning lever 40 or on the two tensioning levers 40 and 41 simultaneously, upon opening. It would be of course possible, according to the same principle, to have three or more parallel levers.

Tous les éléments des moyens de serrage sont de préférence réalisé en métal.All the elements of the clamping means are preferably made of metal.

Les moyens de serrage constitués d'un levier-tendeur unique ou d'un levier-tendeur double on été décrits à titre d'exemple pour la fermeture et le serrage du pied mais il serait possible d'utiliser des moyens identi ques pour la fermeture et le serrage d'une autre partie de la chaussure, par exemple la fermeture de la tige 2. Les têtes de câble pourraient en outre être réalisées d'une autre manière.The clamping means consisting of a single tensioner lever or a double tensioner lever have been described by way of example for closing and tightening the foot but it would be possible to use identical means for closing and tightening another part of the shoe, for example closing the upper 2. The cable heads could also be produced in another way.

Compte-tenu de la longueur du levier-tendeur, respectivement des têtes de câble 29 et 30, on dispose d'une plage de réglage relativement grande. Il n'est donc pas nécessaire de pouvoir régler la position de l'axe d'articulation 28 du levier-tendeur. Un tel réglage pourrait toutefois sans autre être prévu en remplaçant l'étrier représenté par un étrier comportant une série d'encoche, l'axe 28 du levier-tendeur pouvant être engagé dans différentes encoches de l'étrier en position de relaxation.Given the length of the tensioning lever, respectively of the cable heads 29 and 30, there is a relatively large adjustment range. It is therefore not necessary to be able to adjust the position of the hinge pin 28 of the tensioning lever. Such an adjustment could, however, without other provision be made by replacing the stirrup represented by a stirrup comprising a series of notches, the axis 28 of the tensioning lever being able to be engaged in different notches of the stirrup in the relaxed position.

Le dispositif de fermeture selon l'invention peut être utilisé pour toute chaussure de sport, par exemple pour des chaussures de ski de fond ou pour des chaussures de patinage.The closure device according to the invention can be used for any sports shoe, for example for cross-country ski boots or for skating shoes.
