Abstract

The ski boot comprises sole (3) and an ankle part (2) enveloping the foot and the heel. A second boot part is constituted by a collar (4) articulated to the ankle part so as to allow a front to rear movement of the collar. A collar retainer is constituted by a stop (11) and a deformable resilient strip (6).

Description

La présente invention a pour objet une chaussure de ski comprenant une première partie constituée essentiellement d'une semelle et d'une tige enveloppant le pied et la région malléolaire et une seconde partie constituée d'un collier articulé par rapport à la tige de manière à permettre un mouvement du collier d'avant en arrière et inversement, et des moyens de retenue du collier s'opposant au basculement du collier vers l'arrière, mais cédant lorsque l'effort tendant à faire basculer le collier dépasse une valeur déterminée.The present invention relates to a ski boot comprising a first part constituted essentially a sole and an enveloping upper the foot and the malleolar region and a second part consisting of a collar articulated with respect to the rod so as to allow movement of the front collar backwards and vice versa, and means for retaining the collar opposing the tilting of the collar towards the rear but yielding when the effort tending to make tilting the collar exceeds a determined value.

Une telle construction a pour but de protéger le genoux du skieur, plus précisément le ligament croisé antérieur, lorsqu'une force excessive vers l'avant est exercée sur le tibia relativement au fémur. Il a été observé que les ruptures du ligament croisé antérieur dues à un effort excessif de ce type ont augmenté dans une très grande mesure alors que les blessures d'autres types, en particulier les fractures de la jambe et de la cheville ont considérablement diminué en raison des progrès réalisés dans les fixations de sécurité. Un effort excessif sur le ligament croisé antérieur se produit notamment lors d'un passage de bosse, que ce soit en sautant, à la réception, ou en redescendant rapidement la bosse.The purpose of such a construction is to protect the knees of the skier, more specifically the cruciate ligament anterior, when excessive forward force is exerted on the tibia relative to the femur. He was observed that ruptures of the anterior cruciate ligament due to excessive effort of this type have increased in a very large extent while other people's injuries types, especially leg fractures and the ankle have decreased considerably due to progress made in security fasteners. A excessive effort on the anterior cruciate ligament produced in particular during a hump passage, whether either by jumping, at the reception, or by descending quickly the bump.

Du brevet US 5 107 608 on connaít déjà une chaussure équipée d'un dispositif de retenue à déclenchement destiné à protéger le ligament croisé antérieur en cas d'effort excessif. Ce dispositif comprend un verrou en forme de levier coudé du premier genre retenu par un ressort. En cas d'effort excessif sur le collier, le ressort ne parvient plus à retenir le verrou, qui bascule et libère le collier. Un tel dispositif présente l'inconvénient de ne pouvoir être remis en position initiale par le skieur. Il est en outre relativement encombrant.From US patent 5,107,608 we already know a shoe fitted with a trigger restraint intended to protect the anterior cruciate ligament in case of excessive effort. This device includes a lock first kind of angled lever retained by a spring. In case of excessive effort on the collar, the spring can no longer hold the lock, which tilts and releases the necklace. Such a device has the drawback of not being able to be initial position by the skier. It is further relatively bulky.

De la demande internationale WO 97/22 271, on connaít en outre une chaussure de ski également équipée d'un dispositif de retenue déclenchant en cas d'effort excessif sur le collier, vers l'arrière. Ce dispositif est constitué d'une genouillère à ressort, dont l'articulation présente un jeu autorisant un certain déplacement longitudinal de l'axe d'articulation dans l'élément inférieur de la genouillère, et dont les éléments viennent en butée, en un point situé à une certaine distance de l'axe d'articulation, au bout d'une course inférieure au déplacement possible de l'axe. Les éléments de la genouillère étant arrivés en butée et le ressort de la genouillère ayant déjà subit une certaine compression, si l'effort sur le collier continue de croítre il se produit un pivotement des éléments de la genouillère autour de leur point d'appui et la genouillère déclenche si son articulation dépasse l'alignement des points d'articulation de la genouillère à la tige et au collier. Ce dispositif a l'avantage de pouvoir être ramené en position initiale par le skieur, mais il est relativement complexe et encombrant. From international application WO 97/22 271, we know in addition a ski boot also equipped with a restraint system triggering in the event of effort excessive on the collar, backwards. These measures consists of a spring toggle, of which the joint presents a clearance allowing a certain longitudinal displacement of the articulation axis in the lower element of the kneepad, and whose elements come into abutment, at a point located at a certain distance from the hinge pin, at the end of a stroke less than the possible displacement of the axis. The elements of the kneepad having arrived in stop and the spring of the toggle having already undergone some compression, if the effort on the collar continues to grow there is a pivoting of knee brace elements around their fulcrum and the kneepad triggers if its joint exceeds the alignment of the articulation points of the knee protector on stem and collar. This device has the advantage of being able to be brought back to the initial position by the skier, but it's relatively complex and bulky.

La présente invention se propose de réaliser les moyens de retenue du collier de manière beaucoup plus simple et beaucoup moins coûteuse que les dispositifs selon l'art antérieur.The present invention proposes to provide the means much more easily and much less expensive than the devices according to prior art.

La chaussure selon l'invention est caractérisée en ce que les moyens de retenue sont des moyens élastiques bistables constitués d'une butée solidaire d'une partie de la chaussure et d'une pièce élastiquement déformable solidaire de l'autre partie de la chaussure et destinée à être déformée par ladite butée.The shoe according to the invention is characterized in that that the retaining means are elastic means bistables consisting of a stop integral with a part shoe and an elastically deformable part attached to the other part of the shoe and intended to be deformed by said stop.

La pièce élastique est avantageusement constituée d'une simple lame flexible bombée encastrée par ses extrémités dans l'une des parties de la chaussure, de préférence le collier, de manière à former une pièce bistable. La butée peut être venue de moulage avec l'autre pièce.The elastic piece advantageously consists of a simple curved flexible blade embedded by its ends in one part of the shoe, preferably the necklace, so as to form a piece bistable. The stop may have come from molding with the other room.

Il est possible de simplifier encore la construction des moyens de retenue en se passant de pièce élastique additionnelle. La pièce élastiquement déformable est constituée par le collier lui-même, dans lequel est formée une découpe oblongue orientée sensiblement verticalement et présentant deux parties de dimensions au moins égales aux dimensions dudit plot et reliées par un rétrécissement de largeur inférieure à la dimension horizontale du plot, de telle sorte qu'il s'oppose au passage du plot. Dans ce cas, on utilise donc l'élasticité du plastique constituant le collier. It is possible to further simplify the construction retaining means by doing without elastic piece additional. The elastically deformable part is constituted by the necklace itself, in which is formed an oblong cut oriented substantially vertically and having two parts of dimensions at least equal to the dimensions of said stud and connected by a narrowing of width less than the horizontal dimension of the stud, so that it opposes the passage of the stud. In this case, we use therefore the elasticity of the plastic constituting the collar.

Le dessin annexé représente, à titre d'exemple, trois modes d'exécution de l'invention.The accompanying drawing shows, by way of example, three modes of carrying out the invention.

La figure 1 est une vue partielle, de dos, du premier mode d'exécution avant déclenchement.Figure 1 is a partial view, from the back, of the first mode of execution before triggering.

La figure 2 est une vue partielle de côté, du même mode d'exécution, dans laquelle un arraché permet de voir le dispositif bistable.Figure 2 is a partial side view, of the same mode of execution, in which a snatch allows to see the bistable device.

La figure 3 est une vue analogue à la figure 1 montrant le dispositif bistable après déclenchement.Figure 3 is a view similar to Figure 1 showing the bistable device after triggering.

La figure 4 est une vue de dos du deuxième mode d'exécution.Figure 4 is a back view of the second mode of execution.

La figure 5 est une vue de côté du troisième mode d'exécution.Figure 5 is a side view of the third mode of execution.

La chaussure de ski partiellement représentée aux figures 1 à 3, comprend essentiellement une coque 1, formant une tige 2 entourant le pied et la cheville au niveau des malléoles et une semelle 3, et un collier de bas de jambe 4 articulé sur la coque 1 au niveau des malléoles en deux points opposés 5. Le collier 4 est retenu contre un basculement arrière par une lame flexible 6, par exemple en acier, bombée vers le bas et retenue par ses extrémités dans deux logements 7 et 8 du collier 4 qui présente à l'arrière une découpe concave 9 s'étendant au-dessus de la lame 6. En dessous de la lame 6, la tige 2 présente une portée 10 au milieu de laquelle est formée une butée en forme de bossage 11 venant en contact avec le milieu de la lame 6. Les moyens de retenue sont dans un premier état stable.The ski boot partially shown in Figures 1 to 3, essentially comprises a shell 1, forming a rod 2 surrounding the foot and the ankle at level of the malleoli and a sole 3, and a collar of lower leg 4 articulated on the shell 1 at the level of malleoli at two opposite points 5. The collar 4 is retained against rear tilting by a blade flexible 6, for example steel, curved downwards and retained by its ends in two housings 7 and 8 collar 4 which has a cutout at the back concave 9 extending above the blade 6. Below of blade 6, rod 2 has a bearing surface 10 at middle of which is formed a stop in the form of boss 11 coming into contact with the middle of the blade 6. The retaining means are in a first state stable.

Lorsque le collier 4 est sollicité en basculement vers l'arrière, le bossage 6 exerce un effort de flexion sur la lame 6 dont les extrémités viennent s'arc-bouter contre le fond des logements 7 et 8 en offrant ainsi une résistance à la flexion de la lame. Lorsque l'effort sur le collier dépasse une valeur déterminée, la lame 6 se déforme jusqu'à basculement dans son second état stable représenté à la figure 3, état dans lequel elle prend une position bombée vers le haut, dans l'échancrure 9.When the collar 4 is biased towards the rear, the boss 6 exerts a bending force on the blade 6 whose ends are braced against the bottom of housings 7 and 8 thus offering resistance to bending of the blade. When the force on the collar exceeds a determined value, the blade 6 deforms until tipping in its second stable state shown in Figure 3, state in which it takes a domed up position, in notch 9.

La tige 2 est munie d'un téton 12 faisant saillie au-dessus de la lame 6. Ce téton 12 permet de ramener la lame 6 dans son premier état stable, figure 1, par la simple flexion de la jambe : dans la position représentée à la figure 3, la lame 6 vient en effet buter contre le téton 12 lors de cette flexion.The rod 2 is provided with a stud 12 protruding above of blade 6. This stud 12 makes it possible to bring the blade 6 in its first stable state, FIG. 1, by the simple bending of the leg: in the position shown in Figure 3, the blade 6 comes indeed abut against the stud 12 during this bending.

Ce mode d'exécution présente en outre l'avantage de permettre d'adapter la résistance au déclenchement à la morphologie de l'utilisateur par un choix adéquat de la lame 6.This embodiment also has the advantage of allow the trigger resistance to be adapted to the user morphology by an adequate choice of the blade 6.

Dans le second mode d'exécution, le dos de la tige 2 est muni d'un plot 13 de forme ovale et le collier présente une découpe 14 de forme oblongue dans laquelle est engagé le plot 13. La découpe 14 est orientée sensiblement verticalement et présente deux parties 15 à 16 de dimensions telles que le plot 13 peut y être logé dans toutes ses positions angulaires avec un faible jeu. Ces deux parties 15 et 16 sont reliées par un rétrécissement 17 de largeur inférieure à la plus grande dimension transversale du plot 13. Le plot 13 est muni d'une fente de vis 18 permettant son entraínement en rotation au moyen d'une pièce de monnaie.In the second embodiment, the back of the rod 2 is provided with an oval stud 13 and the collar has an oblong cutout 14 in which is engaged the stud 13. The cutout 14 is oriented substantially vertically and has two parts 15 to 16 of dimensions such that the stud 13 can be there housed in all its angular positions with a low clearance. These two parts 15 and 16 are connected by a narrowing 17 of width less than the most large transverse dimension of the stud 13. The stud 13 is provided with a screw slot 18 allowing its rotational drive by means of a piece of change.

En position de descente, le plot 13 est engagé dans la partie inférieure 15 de la découpe 14. Il occupe la position angulaire représentée sur le dessin.In the descent position, the stud 13 is engaged in the lower part 15 of the cutout 14. It occupies the angular position shown in the drawing.

Tant que l'effort de basculement vers l'arrière sur le collier ne dépasse pas la valeur de sécurité déterminée, le collier 4 est retenu en position par le plot 13 qui vient buter contre le rétrécissement 17. Si cet effort dépasse la valeur déterminée, le plot 13 traverse le rétrécissement 17 en déformant élastiquement la matière plastique du collier 4. Il y a déclenchement. Pour replacer le collier en position de descente il suffit de positionner le plot 13 en position de marche. Cette position est obtenue en faisant tourner le plot 13 de 90°. Dans cette position le plot 13 traverse librement le rétrécissement 15 et autorise donc un mouvement du collier relativement à la tige.As long as the rearward tilting force on the collar does not exceed the safety value determined, the collar 4 is retained in position by the stud 13 which abuts against the narrowing 17. If this effort exceeds the determined value, the pad 13 crosses the narrowing 17 while deforming elastically the plastic of the collar 4. There are trigger. To replace the collar in the position downhill just position the stud 13 in walking position. This position is obtained by rotating the stud 13 by 90 °. In this position the stud 13 freely crosses the narrowing 15 and therefore allows movement of the collar relative to the rod.

Une inversion cinématique serait bien entendu possible, le plot étant solidaire du collier et la tige présentant le rétrécissement déformable élastiquement. A kinematic inversion would of course be possible, the stud being integral with the collar and the rod exhibiting elastically deformable narrowing.

Selon une variante non représentée, le plot 13 pourrait présenter des paires de facettes définissant différentes largeurs de plot. Au moins deux paires de facettes présentent des distances, entre facettes, supérieures à la largeur du rétrécissement 15. Selon l'orientation du plot, la résistance à son passage à travers le rétrécissement 17 sera plus ou moins élevée.According to a variant not shown, the stud 13 could present pairs of facets defining different stud widths. At least two pairs of facets have distances, between facets, greater than the width of the narrowing 15. According to the orientation of the stud, the resistance to its passage to through the narrowing 17 will be more or less high.

Le principe du second mode d'exécution est également applicable à une chaussure dont le collier est articulé par l'arrière à l'arrière de la coque. Un exemple d'exécution est représenté à la figure 5. La chaussure est équipée d'un collier de bas de jambe 19 articulé en 20 à l'arrière de la tige 2. Le collier est retenu contre un basculement en arrière par un plot 21, analogue au plot 13, solidaire de la tige 2, sur le côté de cette tige, et engagé dans une découpe oblongue 22 formée dans une plaquette 23, en métal ou en plastique fixée obliquement sur le collier 19. La découpe 22 présente, de manière analogue à la découpe 14, deux parties 24 et 25 de dimensions sensiblement égales à celles du plot 21 et reliées par un rétrécissement 26 de largeur inférieure à la grande dimension du plot 21.The principle of the second embodiment is also applicable to a shoe with a hinged collar from the back to the back of the hull. An example Figure 5 shows the execution shoe. is fitted with a lower leg collar 19 hinged in 20 behind the rod 2. The collar is retained against tilting backwards by a stud 21, similar to stud 13, secured to rod 2, on the side of this rod, and engaged in an oblong cut 22 formed in a plate 23, made of metal or plastic fixed obliquely on the collar 19. The cutout 22 present, similar to the cutout 14, two parts 24 and 25 of substantially dimensions equal to those of stud 21 and connected by a narrowing 26 of width less than large dimension of the stud 21.

En position de descente, le plot 21 est engagé dans la partie 24 de la découpe.In the descent position, the stud 21 is engaged in the part 24 of the cut.

En disposant des plaquettes 23 de rigidité différentes il est possible d'adapter la résistance au déclenchement à la morphologie de l'utilisateur. Un changement de plaquette peut être effectué au gré de l'utilisateur.By having plates 23 of different stiffness it is possible to adapt the resistance to triggering the user's morphology. A plate change can be made at the option of the user.

Dans le mode d'exécution selon la figure 4, la découpe 14 pourrait également être formée dans une plaquette analogue à la plaquette 23. Inversement, dans le mode d'exécution selon la figure 5, la découpe 22 pourrait être formée dans le plastique du collier.In the embodiment according to FIG. 4, the cutting 14 could also be formed in a wafer similar to the wafer 23. Conversely, in the mode of execution according to FIG. 5, the cutout 22 could be formed in the plastic of the collar.
