Abstract

Ski boot having an articulated shank comprising means for fixing or releasing the shank for rotation, means for adjusting the inclination of the shank and an elastic element (15), the elasticity of which is adjustable. The adjustable inclination is achieved by means of a shank in two parts, the length of which is adjustable by means of a button (12). The locking or the release for rotation is obtained by means of a sliding locking member (24) interacting with a V-shaped bolt (16) itself interacting with cut-outs (19) in a cradle fixed to the shank (2). The elasticity of the elastic element (15) is ensured by the displacement of a sliding rigid sleeve (19) around the elastic element (15), which displacement is controlled by a button (32).

Description

La présente invention a pour objet une chaussure de ski constituée d'au moins une partie inférieure des­tinée à entourer le pied et le talon 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 des moyens pour fixer ou libérer la tige en rotation rela­tivement à la partie inférieure, des moyens de réglage de l'inclinaison de la tige relativement à la partie inférieure de la chaussure par un système de vis/écrou, un élément élastique et des moyens de réglage de l'élasticité de cet élément élastique.The subject of the present invention is a ski boot consisting of at least one lower part intended to surround the foot and the heel and a rod articulated on this lower part and comprising, at the rear, means of connection between the upper and the lower part, these connecting means comprising means for fixing or releasing the rod in rotation relative to the lower part, means for adjusting the inclination of the upper relative to the lower part of the shoe by a system of screw / nut, an elastic element and means for adjusting the elasticity of this elastic element.

Une chaussure munie de moyens de verrouillage de la tige susceptibles d'être déverrouillés pour permettre l'oscillation de cette tige et des moyens permettant de régler l'inclinaison de la tige en position verrouil­lée, est décrite dans le brevet FR 2 491 304. Le dispo­sitif utilisé comprend un levier articulé à son extré­mité sur un étrier solidaire de la partie intérieure de la 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. La tige filetée est munie de moyens de préhension permettant de la faire tourner pour déplacer l'écrou baladeur. Il a été envisagé de remplacer la biellette par une liaison élastique régla­ble telle que décrite dans le brevet US 3 619 914. L'introduction d'un tel mécanisme élastique augmente­rait toutefois considérablement l'encombrement du dis­positif. 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.A shoe provided with rod locking means which can be unlocked to allow the oscillation of this rod and means making it possible to adjust the inclination of the rod in the locked position, is described in patent FR 2 491 304. The device used comprises a lever articulated at its end on a stirrup secured to the inner part of the shoe and at an intermediate point, by a sliding 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. The threaded rod is provided with gripping means making it possible to rotate it to move the sliding nut. It has been envisaged to replace the link by an adjustable elastic connection as described in US Pat. No. 3,619,914. The introduction of such an elastic mechanism would however considerably increase the size of the device. 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.

Un dispositif simple, n'utilisant ni vis ni écrou, est connu du brevet CH 549 970. Ce dispositif comprend un 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 on perd le réglage de l'inclinaison de la tige. En outre, le dispositif de liaison ne présente pas d'élasticité.A simple device, using neither screws nor nuts, is known from patent CH 549 970. This device comprises an elastic stirrup, the two bent arms of which engage in holes on each side of an element integral with the lower part of the shoe. When the lever is folded down, the rod is released, but simultaneously the adjustment of the inclination of the rod is lost. In addition, the connecting device has no elasticity.

Un dispositif de liaison élastique à genouillère, ver­rouillable et déverrouillable, est également connu du brevet EP 0 248 149. Ce dispositif ne permet pas un ré­glage de l'inclinaison de la tige.An elastic linkage device with a toggle, lockable and unlockable, is also known from patent EP 0 248 149. This device does not allow adjustment of the inclination of the rod.

La présente invention a pour but de réaliser un dispo­sitif compact permettant de remplir les trois fonctions mentionnées plus haut, soit verrouillage et déverrouil­lage de la tige de la chaussure, réglage de l'inclinai­son de cette tige et réglage de la résistance à la fle­xion de cette tige. Le dispositif ne doit comporter aucune articulation ni levier faisant saillie dans la position déverrouillée et/ou entraîné en oscillation lors de la marche.The present invention aims to achieve a compact device for fulfilling the three functions mentioned above, either locking and unlocking the upper of the shoe, adjusting the inclination of this upper and adjusting the resistance to flexing of this rod. The device must not include any articulation or lever protruding in the unlocked position and / or driven in oscillation during walking.

La chaussure selon l'invention est caractérisée par le fait que les moyens de liaison comprennent une barre en deux parties reliées entre elles par une partie file­tée, s'étendant parallèlement au dos de la tige et dont l'extrémité inférieure est attachée à la partie infé­rieure de la chaussure, un bouton de commande solidaire de la partie supérieure de la tige pour le réglage de la longueur de la barre, un manchon élastique en maté­riau non compressible entourant la tige et travaillant en compression entre une butée et un organe de ver­rouillage monté coulissant sur la tige, entre l'élément élastique et ledit bouton, ledit organe de verrouil­lage coopérant, pour le verrouillage de la tige sur la partie inférieure de la chaussure, avec au moins un cran prévu dans la tige, un organe de commande de l'or­gane de verrouillage monté coulissant parallèlement à la tige et susceptible d'occuper deux positions sta­bles, l'une de verrouillage et l'autre de déverrouil­lage de la tige, un manchon rigide coulissant entourant le manchon élastique et des moyens pour déplacer ledit manchon rigide le long du manchon élastique afin de mo­difier la longueur de la partie de l'élément élastique située hors du manchon rigide et par conséquent suscep­tible de se déformer en expansion.The shoe according to the invention is characterized in that the connecting means comprise a bar in two parts connected to each other by a threaded part, extending parallel to the back of the upper and whose lower end is attached to the part lower of the shoe, a control button secured to the upper part of the upper for adjusting the length of the bar, an elastic sleeve of non-compressible material surrounding the upper and working in compression between a stop and a locking member slidably mounted on the upper, between the elastic element and said button, said locking member cooperating, for locking the upper on the lower part of the shoe, with at least one notch provided in the rod, a control member of the locking member mounted to slide parallel to the rod and capable of occupying two stable positions, one for locking and the other for unlocking the rod, a rigid sliding sleeve surrounding the elastic sleeve and means for moving said rigid sleeve along the elastic sleeve in order to modify the length of the part of the elastic element situated outside the rigid sleeve and consequently liable to deform in expansion.

La seule articulation est constituée par l'attachement de la barre de liaison à la partie inférieure de la chaussure, les autres organes étant coulissants.The only articulation is formed by the attachment of the connecting bar to the lower part of the shoe, the other members being sliding.

L'organe de verrouillage est de préférence constitué par un élément monté élastiquement ou travaillant élas­tiquement en flexion, mais il pourrait également effec­tuer une simple rotation autour de la barre.The locking member is preferably constituted by an elastically mounted element or working elastically in bending, but it could also perform a simple rotation around the bar.

Le dispositif peut être réalisé de façon particulière­ment compacte en prévoyant une commande du manchon ri­gide coulissant à travers une découpe de l'organe de commande de l'organe de verrouillage.The device can be produced in a particularly compact manner by providing control of the rigid sleeve sliding through a cutout in the control member of the locking member.

La chaussure est une chaussure analogue à la chaussure représentée à la figure 1 du brevet FR 2 491 304 et elle comprend comme elle une partie inférieure ou bas de coque 1 entourant le pied et le talon et une tige 2 articulée sur la partie inférieure. On a également re­présenté schématiquement les extrémités des deux bou­cles supérieures 3 et 4 pour le serrage de la tige. Cette tige 2 présente un dos plat 5 muni d'une découpe rectangulaire dans laquelle est fixé un berceau métal­lique 6 de forme rectangulaire et présentant notamment deux parois latérales verticales parallèles 7 et 8. Le dispositif de liaison, représenté seul aux figures 2 et 3, est logé dans le berceau 6.The shoe is a shoe similar to the shoe shown in FIG. 1 of patent FR 2 491 304 and like it includes a lower or lower part of the shell 1 surrounding the foot and the heel and a rod 2 articulated on the lower part. The ends of the two upper loops 3 and 4 have also been shown diagrammatically for tightening the rod. This rod 2 has a flat back 5 provided with a rectangular cutout in which is fixed a metal cradle 6 of rectangular shape and having in particular two parallel vertical side walls 7 and 8. The connection device, shown alone in FIGS. 2 and 3, is housed in cradle 6.

Ce dispositif de liaison comprend une barre cylindrique 9 dont l'extrémité inférieure est munie d'un trou 10 par lequel la barre 9 est attachée au bas de coque 1 au moyen d'un axe 11. L'extrémité supérieure 9a de la bar­re 9 est filetée et vient se visser dans un bout de tige 96 solidaire d'un bouton 12 actionnable manuelle­ment. La barre 9 est donc de longueur variable. Autour de la barre 9 est monté un anneau 13 venant s'appuyer sur le fond 6a du berceau 6 qui constitue une butée pour le dispositif de liaison. L'anneau 13 est solidai­re d'un cylindre rigide 14. Au-dessus de ce cylindre 14 est placé un manchon cylindrique 15 en matériau élas­tique non compressible en volume et également traversé par la barre 9. Entre le bouton 12 et le manchon élas­tique 15 est monté un verrou 16 entre une plaquette carrée 18 et la partie coudée 33a d'une plaque 33 s'étendant parallèlement à la barre 9. La plaquette 18 et la partie coudée 33a jouent le rôle de rondelles montées librement sur la barre 9. Autour du manchon élastique 15 est monté un manchon rigide 19 de diamètre intérieur juste suffisant pour permettre à ce manchon 19 de coulisser sur le manchon élastique 15 pour modi­fier la longueur de la partie du manchon élastique 15 située hors du manchon 19, manière à ajuster la ré­sistance élastique du manchon élastique 15 comme décrit dans le brevet EP 0 206 394. Le manchon 15 est par exemple en caoutchouc. Le manchon rigide 19 est soli­daire d'un bouton 32 susceptible d'être déplacé selon la double flèche F1 au-dessus de la plaque 33.This connecting device comprises a cylindrical bar 9, the lower end of which is provided with a hole 10 by which the bar 9 is attached to the bottom of the shell 1 by means of a pin 11. The upper end 9a of the bar 9 is threaded and is screwed into a rod end 96 secured to a button 12 which can be actuated manually. The bar 9 is therefore of variable length. Around of the bar 9 is mounted a ring 13 coming to bear on the bottom 6a of the cradle 6 which constitutes a stop for the connection device. The ring 13 is integral with a rigid cylinder 14. Above this cylinder 14 is placed a cylindrical sleeve 15 of elastic material not compressible in volume and also crossed by the bar 9. Between the button 12 and the elastic sleeve 15 is mounted a lock 16 between a square plate 18 and the bent part 33a of a plate 33 extending parallel to the bar 9. The plate 18 and the bent part 33a play the role of washers freely mounted on the bar 9. Around of the elastic sleeve 15 is mounted a rigid sleeve 19 of internal diameter just sufficient to allow this sleeve 19 to slide on the elastic sleeve 15 to modify the length of the part of the elastic sleeve 15 located outside of the sleeve 19, so as to adjust the resistance elastic of the elastic sleeve 15 as described in patent EP 0 206 394. The sleeve 15 is for example made of rubber. The rigid sleeve 19 is integral with a button 32 capable of being displaced according to the double arrow F1 above the plate 33.

Le verrou 16 est constitué de deux bras 20 et 21 arti­culés entre eux et maintenus écartés en V par un res­sort 35. Ces bras sont munis d'ergots 22, respective­ment 23 dirigés latéralement vers l'extérieur. Le ver­rou 16 coopère avec un organe de commande 24 constitué par une pièce de forme générale rectangulaire montée coulissante sur le berceau 7. Dans sa partie supérieu­re, l'organe de commande 24 présente un découpe 25 de forme triangulaire dont les deux côtés 26 et 27 consti­tuent des rampes pour l'actionnement du verrou 16. A son sommet, le triangle 25 est tronqué et les extrémi­tés des rampes 26 et 27 aboutissent respectivement dans des logements ou crans 28 et 29. Dans la position re­présentée aux figures 1 et 2, les ergots 22 et 23 du verrou 16 sont engagés respectivement dans des découpes rectangulaires 30 et 31 prévues dans les parois 7 et 8 du berceau 6.The latch 16 consists of two arms 20 and 21 hinged together and kept apart in V by a spring 35. These arms are provided with pins 22, 23 respectively directed laterally outwards. The latch 16 cooperates with a control member 24 consisting of a generally rectangular piece slidably mounted on the cradle 7. In its upper part, the control member 24 has a cutout 25 of triangular shape, the two sides 26 and 27 constitute ramps for actuating the latch 16. At its apex, the triangle 25 is truncated and the ends of the ramps 26 and 27 end respectively in housings or notches 28 and 29. In the position shown in FIGS. 1 and 2, the lugs 22 and 23 of the latch 16 are engaged respectively in rectangular cutouts 30 and 31 provided in the walls 7 and 8 of the cradle 6.

Dans la position représentée à la figure 1 le verrou 16 est écarté et ses ergots 22 et 23 sont engagés dans les découpes 30 et 31 de la tige, dans lesquelles ils vien­nent buter contre les bords supérieurs de ces découpes, en obligeant la tige 2 à prendre une certaine inclinai­son vers l'avant de la chaussure position dite "avancée" pour skier. Les découpes 30 et 31 présentent un large dégagement vertical en dessous du verrou 16 de manière à permettre la flexion de la tige lors de la descente. Pour libérer la tige 2, il suffit de pousser l'organe de commande 24 vers le haut dans le sens de la flèche F2. Le verrou 16 est alors refermé par les rampes 26 et 27, les bras 20 et 21 du verrou venant se loger dans les logements 28 et 29, comme représenté à la figure 3. Le verrou 16 est alors dégagé des décou­pes 30 et 31, de telle sorte qu'il est possible de re­dresser la tige 2 de la chaussure qui peut alors oscil­ler sur le bas de coque 1. C'est la position de repos ou de marche.In the position shown in Figure 1 the latch 16 is spread and its lugs 22 and 23 are engaged in the cutouts 30 and 31 of the rod, in which they abut against the upper edges of these cutouts, forcing the rod 2 to take a certain inclination towards the front of the shoe, the so-called "advanced" position for skiing. The cutouts 30 and 31 have a large vertical clearance below the latch 16 so as to allow the rod to bend during the descent. To release the rod 2, it suffices to push the control member 24 upwards in the direction of the arrow F2. The lock 16 is then closed by the ramps 26 and 27, the arms 20 and 21 of the lock being received in the housings 28 and 29, as shown in FIG. 3. The lock 16 is then released from the cutouts 30 and 31, so that it is possible to straighten the upper 2 of the shoe which can then oscillate on the bottom of the shell 1. This is the rest or walking position.

C'est aussi dans cette position que l'on peut régler l'inclinaison de la tige 2 en position verrouillée en tournant le bouton 12. A cet effet on dégage le dispo­sitif de liaison de son berceau 6 en le faisant bascu­ler en arrière autour de l'axe 11, comme représenté à la figure 5. Dans cette position il est aisé de saisir le bouton 12.It is also in this position that the inclination of the rod 2 can be adjusted in the locked position by turning the knob 12. To this end, the connecting device is released from its cradle 6 by tilting it back around axis 11, as shown in FIG. 5. In this position it is easy to grasp the button 12.

La rotation du bouton 12 a pour effet d'allonger ou de raccourcir la longueur de la barre 9, c'est-à-dire la distance entre son point d'attache 11 au bas de coque 1 et le verrou 16 et par conséquent de régler l'inclinai­son de la tige 2 de la chaussure. Le dispositif de liaison est ensuite rabattu dans le berceau 6.The rotation of the button 12 has the effect of lengthening or shortening the length of the bar 9, that is to say the distance between its point of attachment 11 to the bottom of the shell 1 and the latch 16 and consequently of adjust the inclination of the upper 2 of the shoe. The connecting device is then folded back into the cradle 6.

Pour revenir en position de descente, il suffit de repousser vers le bas dans la direction de la flèche F3 l'organe de commande 24 pour libérer le verrou 16. A la prochaine flexion de la tige 2 vers l'avant, le verrou 16 s'engage alors dans les découpes 30 et 31.To return to the descent position, it suffices to push down in the direction of arrow F3 the control member 24 to release the lock 16. When the rod 2 is next bent forward, the lock 16 s 'then engages in the cutouts 30 and 31.

Comme déjà dit plus haut, le bouton 32 permet de déplacer le manchon rigide 19 le long du manchon élastique 15 et par conséquent de modifier la longueur de la partie élastique du manchon 15 située en dehors du manchon rigide 19, susceptible de se déformer en expansion sous l'effet d'une compression axiale, c'est-­à-dire de modifier la dureté de l'amortisseur élastique constituée par le manchon élastique 15 lorsque la tige 2 de la chaussure est sollicitée vers l'arrière. Dans l'exemple représenté, le manchon mobile 19 peut être verrouillé dans trois positions différentes au moyen d'une liaison rotative entre le manchon 19 et son bouton 32 et d'une partie intermédiaire oblongue 36, aux extrémités arrondies, coopérant avec une fente 37 de la plaque 33 reliant trois découpes circulaires 38, 39 et 40 de diamètre correspondant à la longueur de la partie oblongue 36. En tournant le bouton 32 il est possible d'orienter la partie oblongue 36 parallèlement à la fente 37 de telle sorte qu'il est possible de déplacer cette partie oblongue 36 d'une extrémité à l'autre de la fente 37. En ramenant la partie oblongue 36 dans une position transversale à la fente 37 dans l'une des découpes circulaires 38, 39 ou 40, le bouton 32 est verrouillé dans cette position. Il serait bien entendu possible d'augmenter le nombre de positions verrouillées.As already said above, the button 32 makes it possible to move the rigid sleeve 19 along the elastic sleeve 15 and consequently to modify the length of the elastic part of the sleeve 15 situated outside of the rigid sleeve 19, liable to deform by expanding under the effect of axial compression, that is to say to modify the hardness of the elastic damper constituted by the elastic sleeve 15 when the upper 2 of the shoe is biased backwards. In the example shown, the movable sleeve 19 can be locked in three different positions by means of a rotary connection between the sleeve 19 and its button 32 and an oblong intermediate part 36, with rounded ends, cooperating with a slot 37 of the plate 33 connecting three circular cutouts 38, 39 and 40 of diameter corresponding to the length of the oblong part 36. By turning the button 32 it is possible to orient the oblong part 36 parallel to the slot 37 so that it is possible to move this oblong part 36 from one end to the other of the slot 37. By bringing the oblong part 36 in a position transverse to the slot 37 in one of the circular cutouts 38, 39 or 40, the button 32 is locked in this position. It would of course be possible to increase the number of locked positions.

Il serait en outre possible d'introduire dans le dispo­sitif un élément élastique pour la flexion de la tige de la chaussure vers l'avant. Ceci pourrait se faire simplement en intercalant un ressort de traction dans la barre 9 ou un ressort de compression entre le bouton 12 et la plaquette 18. Ce ressort de compression pour­rait être remplacé par un dispositif réglable analogue aux manchons 15 et 19.It would also be possible to introduce into the device an elastic element for bending the upper of the shoe forward. This could be done simply by inserting a tension spring in the bar 9 or a compression spring between the button 12 and the plate 18. This compression spring could be replaced by an adjustable device similar to the sleeves 15 and 19.

Le verrou 16 pourrait être exécuté selon de nombreuses variantes. Il pourrait par exemple être constitué d'une seule pièce en V flexible ou d'une pièce circulaire montée rotativement autour de la barre 9 et munie de deux doigts radiaux, l'un constituant le verrou et l'autre un bras d'actionnement coopérant avec une rainure oblique de l'organe de commande 24, dont le dé­placement entraînerait le verrou en rotation. Le verrou pourrait être également constitué de deux tiges tra­vaillant radialement en translation et munies chacune d'une bras perpendiculaire aux tiges et coopérant res­pectivement avec deux rainures obliques de l'organe de commande 24.The lock 16 could be executed in many variants. It could for example consist of a single flexible V-shaped piece or of a circular piece rotatably mounted around the bar 9 and provided with two radial fingers, one constituting the lock and the other a cooperating actuating arm with an oblique groove of the control member 24, the displacement of which would cause the bolt to rotate. The lock could also consist of two rods working radially in translation and each provided with an arm perpendicular to the rods and cooperating respectively with two oblique grooves of the control member 24.
