Abstract

The boot is composed of a lower shell (1), on which an upper (2) is articulated about a pivot axis (5) coinciding at least approximately with the joint of the foot. The shell (1) has on the outside, at the rear, a rounded portion (12), the radius of curvature of which is centered on the pivot axis (5), to allow the upper (2) to tilt to the rear. Means, such as ribs (17), are provided inside the part (11) of the shell in order to limit the space intended for receiving the skier's heel.

Description

La présente invention à pour objet une chaussure de ski en matière au moins semi-rigide constituée d'une coque comprenant la semelle et entourant le pied et le talon et d'une tige articulée sur la coque autour d'un axe transversal et dont au moins une partie est basculable en arrière sur la coque, et comprenant en outre, à l'arrière, un mécanisme de liaison entre la coque et la tige constitué d'un levier traversant la partie basculable de la tige et articulé par son extrémité inférieure sur la coque et relié par une biellette à ladite partie basculable de la tige, le levier et la biellette constituant une articulation à genouillère permettant soit d'immobiliser la tige relativement à la coque dans une position inclinée en avant pour la pratique du ski, soit de libérer la tige en lui permettant d'osciller sur la coque pour la marche et en position de repos.The present invention relates to a ski boot made of at least semi-rigid material consisting of a shell comprising the sole and surrounding the foot and the heel and a rod articulated on the shell around a transverse axis and of which at at least one part is tiltable back on the shell, and further comprising, at the rear, a connection mechanism between the shell and the rod consisting of a lever passing through the tiltable part of the rod and articulated by its lower end on the hull and connected by a connecting rod to said tiltable part of the rod, the lever and the rod constituting a toggle joint making it possible either to immobilize the rod relative to the hull in a position inclined forward for skiing, or release the rod allowing it to oscillate on the shell for walking and in the rest position.

La tige peut être en une pièce, comme c'est le cas des chaussures à chaussage par le haut ou en deux pièces, comme c'est le cas des chaussures à chaussage par l'arrière.The upper may be in one piece, as is the case for shoes with a top shoe or in two pieces, as is the case for shoes with a back shoe.

Une chaussure de ce type est connue du brevet CH-A 639 250 de la déposante. Pour passer de la position ouverte, libre, du mécanisme à la position fermée, bloquée, du mécanisme, l'utilisateur doit appuyer fortement sur le levier pour le rabattre contre la chaussure. Lors de ce mouvement de fermeture, il doit en outre vaincre la résistance de la chaussure elle-même pour passer au delà de la position neutre de la genouillère, c'est-à-dire de la position dans laquelle ces trois articulations sont alignées. La position dans laquelle le skieur doit appuyer sur le levier est en outre peu commode.A shoe of this type is known from patent CH-A 639 250 of the applicant. To move from the open, free position of the mechanism to the closed, locked position of the mechanism, the user must press the lever strongly to fold it against the shoe. During this closing movement, it must also overcome the resistance of the shoe itself to pass beyond the neutral position of the toggle, that is to say the position in which these three joints are aligned. The position in which the skier must press the lever is also inconvenient.

La présente invention a pour but de faciliter la fermeture du mécanisme de liaison.The present invention aims to facilitate the closure of the connecting mechanism.

A cet effet, la chaussure selon l'invention est caractérisée par le fait qu'elle comprend un corps élastique logé dans une cavité formée entre la tige et l'une des extrémités du mécanisme de liaison articulée à la tige, ce logement étant limité vers l'extérieur par un prolongement de ladite extrémité dirigé sensiblement parallèlement à l'axe du mécanisme de liaison au-delà de son axe d'articulation à la chaussure, de telle sorte que ce corps élastique est comprimé lors de l'ouverture du mécanisme de liaison.To this end, the shoe according to the invention is characterized in that it comprises an elastic body housed in a cavity formed between the upper and one of the ends of the linkage mechanism articulated to the upper, this housing being limited towards the outside by an extension of said end directed substantially parallel to the axis of the connecting mechanism beyond its axis of articulation to the shoe, so that this elastic body is compressed when the opening mechanism liaison.

Le corps élastique, par exemple une bille en caoutchouc disposée derrière un prolongement de la biellette, a donc tendance à s'opposer à l'ouverture mécanisme de liaison et par conséquent à favoriser sa fermeture et à maintenir le mécanisme en position fermée. Lorsque le skieur désire passer de la position de repos ou de marche à la position de descente, il n'a pas besoin d'agir sur le levier pour fermer le mécanisme de liaison mais il lui suffit d'agir sur la tige. Dès que la tige est suffisament inclinée, le mécanisme de liaison se ferme automatiquement de lui-même grâce à l'effet du corps élastique disposé à l'extrémité de la biellette. Etant donné que l'inclinaison de la tige peut être provoquée par la flexion de la jambe, la fermeture du mécanisme de liaison peut être réalisée automatiquement. Le levier n'est dès lors plus utilisé que pour l'ouverture par traction sur l'extrémité de celui-ci, ce mouvement de traction étant beaucoup plus facile à exécuter que le mouvement de poussée.The elastic body, for example a rubber ball disposed behind an extension of the link, therefore tends to oppose the opening of the connecting mechanism and therefore to favor its closing and to keep the mechanism in the closed position. When the skier wishes to pass from the rest or walking position to the descent position, he does not need to act on the lever to close the connecting mechanism but he just has to act on the rod. As soon as the rod is sufficiently inclined, the connection mechanism closes automatically by itself thanks to the effect of the elastic body placed at the end of the link. Since the inclination of the rod can be caused by the bending of the leg, the closing of the connecting mechanism can be carried out automatically. The lever is therefore only used for opening by traction on the end thereof, this traction movement being much easier to execute than the pushing movement.

Le corps élastique peut être disposé aussi bien entre la biellette et la tige qu'entre le levier et la coque de la chaussure.The elastic body can be arranged as well between the link and the upper as between the lever and the shell of the shoe.

Additionnellement il est possible de prévoir, au niveau de l'articulation de la biellette au levier, un ressort, par exemple un ressort de torsion, s'opposant également à l'ouverture du mécanisme.Additionally, it is possible to provide, at the articulation of the rod to the lever, a spring, for example a torsion spring, also opposing the opening of the mechanism.

En raison de la présence du corps élastique et, le cas échéant du ressort additionnel, il n'est pas nécessaire que l'axe d'articulation de la biellette au levier dépasse la ligne droite reliant les deux autres articulations du mécanisme, lors de la fermeture du mécanisme, car le corps élastique et, le cas échéant, le ressort additionnel, suffit à empêcher le mécanisme de s'écarter de sa position neutre dans laquelle les trois articulations sont alignées. L'ouverture du mécanisme de liaison s'en trouve facilitée, puisqu'il n'est pas nécessaire d'allonger tout d'abord le mécanisme de liaison et de vaincre la résistance de la chaussure pour atteindre la position d'alignement des articulations.Due to the presence of the elastic body and, where appropriate, the additional spring, it is not necessary for the articulation axis of the link to the lever to exceed the straight line connecting the two other articulations of the mechanism, during the closing of the mechanism, because the elastic body and, if necessary, the additional spring, suffices to prevent the mechanism from deviating from its neutral position in which the three joints are aligned. The opening of the connecting mechanism is thereby facilitated, since it is not necessary to first of all lengthen the connecting mechanism and to overcome the resistance of the shoe to reach the position of alignment of the joints.

En montant l'axe d'articulation de la biellette sur la tige ou l'axe d'articulation du levier sur la coque avec un jeu longitudinal, il est en outre possible de réaliser une liaison élastique en interposant un organe élastique entre ledit axe et une butée solidaire de la tige, respectivement de la coque.By mounting the articulation axis of the link on the rod or the articulation axis of the lever on the shell with a longitudinal clearance, it is also possible to produce an elastic connection by interposing an elastic member between said axis and a stop integral with the rod, respectively with the shell.

Le dessins annexé représente, à titre d'exemple, une forme d'exécution de l'invention.The accompanying drawings show, by way of example, an embodiment of the invention.

  • La figure 1 représente schématiquement et partiellement une chaussure de ski équipée du mécanisme selon l'invention en position fermée.Figure 1 shows schematically and partially a ski boot equipped with the mechanism according to the invention in the closed position.
  • La figure 2 représente le même mécanisme en position ouverte, tige basculée en arrière.Figure 2 shows the same mechanism in the open position, rod tilted back.

La chaussure, partiellement et schématiquement représentée, est constituée d'une coque 1 en matière plastique, venue d'une pièce avec une semelle 2 et entourant le pied et le talon, et d'une tige comportant une partie arrière 3 articulée sur la coque 1 autour d'un axe 4 coïncidant au moins approximativement avec l'articulation du pied du skieur. La tige peut être en une ou deux parties. Dans le cas d'une chaussure à chaussage par l'arrière, les deux parties de la tige sont articulées autour de l'axe 4. Dans les deux cas un large basculement en arrière de la partie 3 de la tige, comme représenté à la figure 2, est possible en raison d'une conformation particulière de la coque dans la région 5 du talon, comme décrit dans la demande de brevet EP-A1 0 229 405 de la déposante. A l'arrière de la chaussure, la coque 1 et la partie de la tige 3 sont reliées par un mécanisme de liaison 6 comprenant un levier 7 dont l'extrémité inférieure est articulée au moyen d'un axe 8 sur la coque 1 et dont un point intermédiaire est articulé au moyen d'un axe 9 à une biellette 10 dont l'autre extrémité est articulée au moyen d'un axe 11 à la tige 3. Le levier 7 traverse une découpe de la tige 3. L'axe 8 de l'articulation du levier 7 à la coque 1 est monté dans un espace 12 de la coque, par exemple entre deux nervures ou dans un dégagement, le talon du chausson intérieur, non représenté, de la chaussure venant buter en 13, comme décrit dans la demande de brevet EP-A1 0 229 405 de la déposante. Le levier présente un bec 14 donnant prise à l'utilisateur pour l'ouverture du mécanisme de liaison 6. Dans un logement 15 de la tige 3, en forme d'alvéole, est fixée une pièce métalique 16 constituée d'une tôle pliée présentant dans sa partie supérieure deux ailes parallèles 17 entre lesquelles est monté l'axe 11 de la biellette. Cet axe 11 est plus précisément monté dans deux lumières opposées 18 des ailes 17, lumières dirigées dans le sens des articulations du mécanisme de liaison 6 et dans lesquelles l'axe 11 peut se déplacer. Comme ceci est mieux visible à la figure 2, la biellette 10 n'est pas réctiligne, mais elle est coudée à angle droit à chacune de ces éxtrémités de telle sorte qu'elle présente intérieurement un profil en U dans lequel est logé un bloc allongé 19 en caoutchouc ou autre élastomère qui s'appuie par son extrémité inférieure contre une partie coudée 20 de la tôle 16 elle-même fixée au moyen d'un rivet sur une membrure 21 de la tige 3. Par son extrémité supérieure, l'élément en caoutchouc 19 s'appuie contre la partie coudée supérieure de la biellette 10 portant l'axe d'articulation 11. La biellette 10 présente en outre un prolongement 22 au delà de l'axe 11, décalé par rapport à cet axe. Ce prolongement 22, la face supérieure de la partie coudée supérieure de la biellette 10 et la partie supérieure de la tôle 16 avec ses ailes 17 définissent un logement 23 dans lequel est logé une bille en caoutchouc 24. Autour de l'axe 9 de l'articulation de la biellette 10 au levier 7 est en outre monté un ressort de torsion hélicoïdal ayant tendance à s'opposer à une ouverture du mécanisme de liaison 6.The shoe, partially and schematically represented, consists of a plastic shell 1, coming in one piece with a sole 2 and surrounding the foot and the heel, and of a rod comprising a rear part 3 articulated on the shell 1 around an axis 4 coinciding at least approximately with the articulation of the skier's foot. The rod can be in one or two parts. In the case of a shoe with a rear boot, the two parts of the upper are articulated around the axis 4. In both cases a large tilting back of the part 3 of the upper, as shown in the Figure 2, is possible due to a particular conformation of the shell in the region 5 of the heel, as described in patent application EP-A1 0 229 405 of the applicant. At the rear of the shoe, the shell 1 and the part of the upper 3 are connected by a connecting mechanism 6 comprising a lever 7 whose lower end is articulated by means of an axis 8 on the shell 1 and whose an intermediate point is articulated by means of an axis 9 to a link 10 whose other end is articulated by means of an axis 11 to the rod 3. The lever 7 passes through a cutout in the rod 3. The axis 8 from the articulation of the lever 7 to the shell 1 is mounted in a space 12 in the shell, for example between two ribs or in a clearance, the heel of the inner liner, not shown felt, of the shoe abutting at 13, as described in patent application EP-A1 0 229 405 of the applicant. The lever has a spout 14 giving the user grip for opening the connection mechanism 6. In a housing 15 of the rod 3, in the form of a cell, is fixed a metal part 16 consisting of a folded sheet having in its upper part two parallel wings 17 between which is mounted the axis 11 of the link. This axis 11 is more precisely mounted in two opposite openings 18 of the wings 17, openings directed in the direction of the joints of the connecting mechanism 6 and in which the axis 11 can move. As is better visible in Figure 2, the rod 10 is not rectilinear, but it is bent at right angles to each of these ends so that it internally has a U-shaped profile in which is housed an elongated block 19 made of rubber or other elastomer which bears by its lower end against a bent part 20 of the sheet 16 itself fixed by means of a rivet on a frame 21 of the rod 3. By its upper end, the element rubber 19 bears against the upper bent part of the link 10 carrying the hinge axis 11. The link 10 further has an extension 22 beyond the axis 11, offset from this axis. This extension 22, the upper face of the upper bent part of the rod 10 and the upper part of the sheet 16 with its wings 17 define a housing 23 in which is housed a rubber ball 24. Around the axis 9 of l the articulation of the link 10 to the lever 7 is further mounted a helical torsion spring tending to oppose an opening of the connecting mechanism 6.

Dans la position fermée représentée du mécanisme de liaison représentée à la figure 1 pour la pratique du ski, la biellette 10 est en butée contre un rebord extérieur coudé 26 de la tôle 16, qui a en outre pour fonction de retenir latéralement l'élément élastique 19, de telle sorte que les articulations 8, 9 et 11 du mécanisme de liaison sont alignées. Dans cette position fermée la tige 3 de la chaussure est maintenue dans une position légèrement inclinée vers l'avant. Bien que les axes d'articulation du mécanisme de liaison 6 soit alignés, le mécanisme ne risque pas de s'ouvrir sous l'effet d'une compression, car la bille de caoutchouc 24, et le ressort 9 s'opposent à cette ouverture. La liaison entre la tige et la coque n'est toutefois pas rigide, mais autorise une certaine flexion élastique en raison de la présence de l'élément élastique 19. En effet, lorsque le skieur fléchit la jambe en entraînant la tige 3, l'axe 11 peut se déplacer dans les lumières 18 en comprimant l'élément élastique 19.In the closed position shown of the connecting mechanism shown in Figure 1 for skiing, the link 10 is in abutment against an angled outer edge 26 of the sheet 16, which also has the function of laterally retaining the elastic element 19, so that the joints 8, 9 and 11 of the connecting mechanism are aligned. In this closed position, the upper 3 of the shoe is held in a position slightly inclined towards the front. Although the axes of articulation of the connecting mechanism 6 are aligned, the mechanism is not likely to open under the effect of compression, because the rubber ball 24, and the spring 9 oppose this opening . The connection between the rod and the shell is not, however, rigid, but allows a certain elastic bending due to the presence of the elastic element 19. In fact, when the skier bends the leg by driving the rod 3, the axis 11 can move in the slots 18 by compressing the elastic element 19.

Lorsque le skieur désire libérer la tige 3, il lui suffit de tirer très légèrement sur le bec 14 du levier 7 dans la direction de la flèche F. Dès que l'axe 9 de l'articulation de la biellette 10 au levier 7 s'écarte de la ligne droite reliant les deux autres articulations 8 et 11, le skieur peut redresser la jambe en entraînant le mécanisme de liaison 6.When the skier wishes to release the rod 3, it suffices for him to pull very slightly on the spout 14 of the lever 7 in the direction of the arrow F. As soon as the axis 9 of the articulation of the link 10 to the lever 7 s' apart from the straight line connecting the other two joints 8 and 11, the skier can straighten the leg by driving the connecting mechanism 6.

Pour déchausser ou chausser, le skieur peut faire basculer la tige, respectivement la partie de la tige 3 vers l'arrière comme représenté à la figure 2. Dans cette position la bille en caoutchouc 24 est fortement comprimée, c'est-à-dire déformée et le ressort de torsion 25 est tendu. Les forces de frottement de la tige sur la coque sont cependant suffisantes pour s'opposer aux couples exercés par les éléments élastiques du mécanisme de liaison qui ont tendance à faire pivoter la tige 3 vers l'avant.To take off or put on the shoes, the skier can tilt the rod, respectively the part of the rod 3 backwards as shown in FIG. 2. In this position the rubber ball 24 is strongly compressed, that is to say deformed and the torsion spring 25 is tensioned. The frictional forces of the rod on the shell are however sufficient to oppose the torques exerted by the elastic elements of the connecting mechanism which tend to pivot the rod 3 forwards.

Une fois chaussé, le skieur redresse la tige et ferme la ou les boucles de la chaussure. Il se trouve alors dans une position correspondant à la position de repos, position dans laquelle le mécanisme de liaison 6 est légèrement ouvert. Dès que le skieur se met en position de descente, c'est-à-dire fléchit la jambe, une traction est exercée sur le mécanisme de liaison 6 qui a tendance à se fermer. Cette fermeture est terminée et assurée par le couple exercé par la bille élastique comprimée 24, dans la direction F2 sur le prolongement 23 de la biellette 10. Il est à noter que le ressort de torsion 25, facultatif, contribue également à cette fermeture, ainsi que l'organe élastique 19. Ces mêmes éléments élastiques assurent le maintient du mécanisme de liaison en position fermée.Once fitted, the skier straightens the upper and closes the shoe buckle (s). It is then in a position corresponding to the rest position, position in which the connecting mechanism 6 is slightly open. As soon as the skier goes into the descent position, that is to say bends the leg, traction is exerted on the connecting mechanism 6 which tends to close. This closure is completed and ensured by the torque exerted by the compressed elastic ball 24, in the direction F2 on the extension 23 of the rod 10. It should be noted that the torsion spring 25, optional, also contributes to this closure, thus as the elastic member 19. These same elastic elements maintain the connection mechanism in the closed position.

L'invention est susceptible de nombreuses variantes d'exécution. La variante principale consiste à prévoir le prolongement 22 à l'extrémité inférieure du levier 7 et à placer la bille de caoutchouc 24 entre ce prolongement et la coque. De même l'axe d'articulation 8 du levier 7 pourrait être monté dans des lumières analogues aux lumières 18 et l'élément élastique 19 pourrait être monté entre l'axe 8 et une butée solidaire de la coque, au-dessus de l'axe 8. Selon une exécution simplifiée, l'élément élastique 19 et les lumières 18 pourraient être supprimés. L'élément élastique 19 pourrait être constitué par tout organe élastique tel qu'un ressort. La bille en caoutchouc 24 pourrait être remplacée par un corps élastique d'une autre forme ou même par un ressort.The invention is susceptible of numerous variants. The main variant consists in providing the extension 22 at the lower end of the lever 7 and in placing the rubber ball 24 between this extension and the shell. Similarly the hinge pin 8 of the lever 7 could be mounted in lights similar to the lights 18 and the elastic element 19 could be mounted between the axis 8 and a stop integral with the shell, above the axis 8. According to a simplified execution, the elastic element 19 and the slots 18 could be eliminated. The elastic element 19 could be constituted by any elastic member such as a spring. The rubber ball 24 could be replaced by an elastic body of another shape or even by a spring.
