Abstract

This ski boot comprises a member for locking the upper in relation to the lower portion of the boot in the downhill running position, in the form of a rocker pivoted to a transverse axis in a cavity formed in the pivoted upper of the boot, and adapted to cooperate with a stop carried by the lower portion of the boot. The rocker can be released from the stop for straightening the skier's leg to a walking or non-skiing position by simply depressing the upper portion of the rocker. When the skier bends his leg the rocker is restored automatically to its locked position by a spring.

Description

La présente invention concerne une chaussure de ski constituée d'au moins une partie inférieure comprenant l'empeigne et d'une tige articulée sur cette partie inférieure, et comprenant un organe encastré et articulé autour d'un axe horizontal, dans une découpe du dos de la tige, cet organe étant susceptible d'occuper deux positions, l'une dans laquelle sa partie inférieure vient buter contre une butée solidaire de la partie supérieure de la chaussure de manière à verrouiller la tige dans une position inclinée vers l'avant de la chaussure, l'autre dans laquelle la tige est redressée et peut légèrement osciller autour de cette position. La position verrouillée de la tige est utilisée durant la pratique du ski, lors de laquelle une position inclinée en avant et relativement rigide de la tige est judicieuse, tandis que la position déverrouillée est utilisée au repos, pour chausser la chaussure ou pour la marche, avec ou sans skis, la liberté d'oscillation de la tige relativement à la partie inférieure de la chaussure permettant le mouvement naturel de la partie inférieure de la jambe par rapport au pied.The present invention relates to a ski boot consisting of at least one lower part comprising the upper and a rod articulated on this lower part, and comprising a recessed member and articulated around a horizontal axis, in a cutout of the back of the upper, this member being capable of occupying two positions, one in which its lower part abuts against a stop integral with the upper part of the shoe so as to lock the upper in a forward inclined position of the shoe, the other in which the upper is straightened and can oscillate slightly around this position. The locked position of the upper is used during skiing, when a tilted forward and relatively rigid position of the upper is advisable, while the unlocked position is used at rest, to put on the boot or for walking, with or without skis, the freedom of oscillation of the upper relative to the lower part of the shoe allowing the natural movement of the lower part of the leg relative to the foot.

Des moyens permettant de verrouiller la tige en position inclinée ou de la libérer ont déjà été proposés, par exemple dans le brevet CH 549970. Ces moyens sont constitués par un coulisseau fixé à son extrémité inférieure à la partie inférieure de la chaussure et coulissant dans une glissière fixée à la tige de la chaussure, la solidarisation du coulisseau dans sa glissière étant assurée par les deux extrémités coudées d'un étrier élastique monté pivotant sur la glissière. Un tel dispositif est relativement compliqué, lourd et encombrant. En outre, l'étrier élastique risque de s'accrocher accidentellement.Means making it possible to lock the rod in an inclined position or to release it have already been proposed, for example in patent CH 549970. These means consist of a slide fastened at its lower end to the lower part of the shoe and sliding in a slide fixed to the upper of the shoe, the connection of the slide in its slide being ensured by the two bent ends of an elastic stirrup pivotally mounted on the slide. Such a device is relatively complicated, heavy and bulky. In addition, the elastic stirrup may accidentally catch on.

On connaît déjà également un dispositif très simple constitué d'une barrette articulée à son extrémité supérieure dans une découpe de la tige et dont l'extrémité inférieure vient en butée contre une butée solidaire de la partie inférieure de la chaussure, lorsque la barrette est rabattue dans la découpe. Cette barrette est munie d'un ergot permettant de soulever la barrette pour la dégager de la butée, de manière à permettre à la tige de la chaussure de se redresser. Pour passer de la position de repos ou de marche à la position verrouillée, il faut simultanément fléchir la jambe et repousser à la main la barrette dans son logement, ce qui est peu commode.There is also already known a very simple device consisting of a bar articulated at its upper end in a cutout of the upper and whose lower end abuts against a stop integral with the lower part of the shoe, when the bar is folded in the cutout. This bar is provided with a lug making it possible to raise the bar to release it from the stop, so as to allow the upper of the shoe to straighten. To move from the rest or walking position to the locked position, you must simultaneously bend your leg and push the bar back by hand into its housing, which is inconvenient.

La présente invention a pour but de réaliser un dispositif aussi simple que le dispositif susmentionné, mais d'une utilisation plus commode et ne présentant pas d'ergot saillant.The object of the present invention is to provide a device as simple as the above-mentioned device, but of more convenient use and not presenting a protruding lug.

Dans la chaussure de ski selon l'invention, l'organe de verrouillage est constitué par une bascule pivotée autour d'un axe traversant la découpe de la tige dans sa partie médiane et associée à un ressort ayanttendance à maintenir la partie inférieure de la bascule contre la chaussure, la partie supérieure de la bascule présentant la forme d'une touche à presser. Il est ainsi possible de déverrouiller la tige par une simple pression sur la touche, tandis que le verrouillage se fait automatiquement, sous l'effet du ressort, lorsque le skieur fléchit la jambe pour se mettre en position de descente. L'organe est en outre parfaitement encastré, sans partie saillante.In the ski boot according to the invention, the locking member is constituted by a rocker pivoted about an axis crossing the cutout of the upper in its middle part and associated with a spring tending to hold the lower part of the rocker against the shoe, the upper part of the rocker having the shape of a button to be pressed. It is thus possible to unlock the rod by a simple press on the key, while the locking is done automatically, under the effect of the spring, when the skier bends his leg to get into the descent position. The organ is also perfectly embedded, without protruding part.

Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'invention.

La chaussure de ski représentée à la fig. 1 est en matière synthétique moulée. Elle est constituée de manière connue en soi, d'une partie inférieure 1 comprenant la semelle et l'empeigne et d'une tige 2 articulée sur la partie inférieure 1 au moyen de deux rivets 3, dont un seulement est visible sur le dessin, l'autre rivet étant situé sur le côté intérieur de la tige. Le bord supérieur 1 a de la partie 1 est entouré largement par la tige à l'avant et à l'arrière de cette tige. Pour sa fermeture, la chaussure est munie, de manière connue, de quatre boucles 4. Le dos de la tige présente une large nervure 5 s'étendant du haut en bas de la tige, présentant une découpe rectangulaire dans laquelle est encastré un organe de verrouillage 6 constitué par une bascule montée autour d'un axe 7 constitué par une goupille traversant la nervure 5.The ski boot shown in FIG. 1 is made of molded synthetic material. It is constituted in a manner known per se, of a lower part 1 comprising the sole and the upper and of a rod 2 articulated on the lower part 1 by means of two rivets 3, only one of which is visible in the drawing, the other rivet being located on the inner side of the rod. The upper edge 1a of part 1 is surrounded largely by the rod at the front and at the rear of this rod. To close it, the shoe is provided, in a known manner, with four loops 4. The back of the upper has a wide rib 5 extending from top to bottom of the upper, having a rectangular cutout in which is embedded a lock 6 constituted by a rocker mounted around an axis 7 constituted by a pin passing through the rib 5.

La découpe 8 dans laquelle est encastré l'organe de verrouillage 6 est visible à la fig. 2, dans laquelle la nervure 5 est représentée en coupe. La bascule 6 présente une partie supérieure 9, au-dessus de son axe de pivotement 7, en forme de touche dont la surface présente une creusure. L'extrémité supérieure de la touche présente un bord saillant 10 destiné à venir buter contre un robord 11 de la découpe 8 pour limiter le basculement de la bascule 6. Autour de l'axe 7 est monté un ressort de torsion 12, logé par ailleurs dans une creusure latérale de la bascule 6, dont l'extrémité 12a s'appuie dans cette creusure et dont l'autre bras 12b présente une extrémité coudée à angle droit qui vient s'appuyer contre la face intérieure de la tige 2, sur le bord de la découpe 8. Ce ressort 12 a tendance à faire tourner la bascule 6 dans le sens horaire, c'est-à-dire à maintenir son extrémité 10 en appui contre le rebord 11. En face de la bascule 6, sur la partie 1 de la chaussure, est fixée une butée 13 constituée par une pièce métallique coudée à l'équerre fixée par un rivet 14. Cette butée 13 est destinée à retenir l'extrémité inférieure de la bascule 6, comme représenté à la fig. 2. La butée 13 vient plus précisément buter dans un décrochement de l'extrémité inférieure de la bascule 6, de telle sorte que son extrémité est recouverte par la bascule et par conséquent invisible. Immédiatement au-dessus de ce décrochement, la bascule 6 présente une nervure transversale 15 en forme de dièdre.The cutout 8 in which the locking member 6 is embedded is visible in FIG. 2, in which the rib 5 is shown in section. The rocker 6 has an upper part 9, above its pivot axis 7, in the form of a key, the surface of which has a recess. The upper end of the key has a projecting edge 10 intended to abut against a valve 11 of the cutout 8 to limit the tilting of the rocker 6. Around the axis 7 is mounted a torsion spring 12, housed elsewhere in a lateral recess of the rocker 6, the end 12a of which rests in this recess and the other arm 12b of which has a bent end at a right angle which comes to bear against the internal face of the rod 2, on the edge of the cutout 8. This spring 12 tends to rotate the rocker 6 clockwise, that is to say to keep its end 10 in abutment against the flange 11. Opposite rocker 6, on the part 1 of the shoe, is fixed a stop 13 constituted by a metal piece bent at the square fixed by a rivet 14. This stop 13 is intended to retain the lower end of the rocker 6, as shown in fig. 2. The stop 13 more precisely abuts in a recess of the lower end of the rocker 6, so that its end is covered by the rocker and therefore invisible. Immediately above this recess, the rocker 6 has a transverse rib 15 in the form of a dihedral.

Partant de la position avancée, de descente, représentée à la fig. 2, lorsque le skieur, en repos, désire libérer la tige 2 de la chaussure, il lui suffit de presser sur la touche 9 comme indiqué par la flèche F à la fig. 3. La bascule 6 se dégage alors de la butée 13 et le skieur peut redresser la jambe, la tige 2 pouvant alors venir dans la position représentée à la fig. 3. La creusure de la surface de la touche 9 facilite cet actionnement et permet même d'utiliser l'extrémité d'un bâton. Lorsque le skieur relâche la pression sur la touche 9, la face intérieure de la bascule 6 vient s'appuyer contre l'extrémité de la butée 13 sur laquelle elle peut glisser au besoin si la tige 2 oscille autour des rivets 3. Dès que le skieur se remet à skier, c'est-à-dire qu'il fléchit légèrement la jambe, la butée 13 glisse sous la rampe supérieure de la nervure 13 en repoussant élastiquement la bascule 6 qui retombe ensuite dans la position verrouillée en butée représentée à la fig. 2.Starting from the advanced, lowering position, shown in fig. 2, when the skier, at rest, wishes to release the upper 2 from the boot, it suffices to press the key 9 as indicated by the arrow F in FIG. 3. The rocker 6 is then released from the stop 13 and the skier can straighten the leg, the rod 2 can then come into the position shown in FIG. 3. The hollow of the surface of the key 9 facilitates this actuation and even allows the end of a stick to be used. When the skier releases the pressure on the button 9, the inner face of the rocker 6 comes to rest against the end of the stop 13 on which it can slide if necessary if the rod 2 oscillates around the rivets 3. As soon as the skier resumes skiing, that is to say that he slightly bends his leg, the stop 13 slides under the upper ramp of the rib 13 by elastically pushing the rocker 6 which then falls back into the locked position as a stop shown in fig. 2.

La construction décrite est bien entendu susceptible de nombreuses variantes d'exécution. Par exemple, la butée 13 pourrait être moulée venue d'une pièce avec la partie 1 de la chaussure. D'autre part, le ressort en cor de chasse 12 pourrait être remplacé par un ressort travaillant en compression entre la touche 9 et la partie 1 de la chaussure. Un tel ressort pourrait être lui-même remplacé par un morceau de caoutchouc.The construction described is of course susceptible of numerous variants. For example, the stop 13 could be molded integrally with the part 1 of the shoe. On the other hand, the hunting horn spring 12 could be replaced by a spring working in compression between the button 9 and the part 1 of the shoe. Such a spring could itself be replaced by a piece of rubber.
