Abstract

The boot comprises an upper (4) hinged (5) with a shell (1). A mechanism allows the upper to be locked to the shell or to be pivoted. This mechanism consists of two links (7, 8) hinged with each other and, on the one hand, with the shell (10) and, on the other hand, with the upper (11). The pin (9) hingeably connecting the links together is accommodated, on the one hand, inside a notch (19b) in the top link (8) and, on the other hand, in a fixed oblong aperture (16). The notch (19b) leads into an oblong aperture (19a) in the top link (8). The mechanism is kept in this locked position by a spring (26). A lever (27) enables the oblong aperture (19a) to be brought opposite the hinging point (9) so that this pin is able to slide inside the superimposed apertures (16, 19a).

Description

La présente invention a pour objet une chaussure de ski en matière au moins semi-rigide constituée d'une partie inférieure comprenant la semelle et entourant le pied et le talon et d'une tige articulée sur la partie inférieure et comprenant, à l'arrière, un mécanisme de liaison entre la tige et la partie inférieure, ce mécanisme comprenant essentiellement deux biellettes articulées entre elles et respectivement à la tige et à la partie inférieure, le mécanisme étant agencé de telle sorte qu'il peut occuper une première position dans laquelle la tige est bloquée relativement à la partie inférieure et une seconde position dans laquelle la tige est libre d'osciller sur la partie inférieure, l'une des biellettes étant munie de moyens d'actionnement manuel.The present invention relates to a ski boot made of at least semi-rigid material consisting of a lower part comprising the sole and surrounding the foot and the heel and of an articulated rod on the lower part and comprising, at the rear , a connecting mechanism between the rod and the lower part, this mechanism essentially comprising two rods hinged together and respectively to the rod and to the lower part, the mechanism being arranged so that it can occupy a first position in which the rod is locked relative to the lower part and a second position in which the rod is free to oscillate on the lower part, one of the rods being provided with manual actuation means.

Une chaussure comprenant un tel mécanisme de liaison est décrite dans le brevet CH-A 639 250 (FR-A 2 491 304). Dans cette chaussure, les biellettes forment une articulation à genouillère. Pour passer de la position ouverte, libre, du mécanisme à la position fermée, ou inversement, le skieur doit agir directement sur l'une des biellettes et dans chaque cas il doit vaincre la résitance de la chaussure elle-même pour passer au-delà de la position, neutre de la genouillère, c'est-à-dire au-delà de la position dans laquelle ses trois articulations sont alignées. Lors de la fermeture de la genouillère, le skieur doit en outre souvent vaincre en plus la résistance offerte par la cheville elle-même, si celle-ci n'est pas fléchie. En outre, lorsque la tige de la chaussure oscille lors de la marche, les articulations de la genouillère sont sans cesse sollicitées. Ces articulations sont généralement dans une position telle que la genouillère offre une résistance non négligeable à la rotation de la tige de la chaussure vers l'arrière.A shoe comprising such a connecting mechanism is described in patent CH-A 639,250 (FR-A 2,491,304). In this shoe, the links form a knee joint. To move from the open, free position, from the mechanism to the closed position, or vice versa, the skier must act directly on one of the links and in each case he must overcome the resistance of the shoe itself to go beyond from the neutral position of the kneepad, that is to say beyond the position in which its three joints are aligned. When closing the kneepad, the skier must also often overcome in addition the resistance offered by the ankle itself, if it is not bent. In addition, when the upper of the shoe oscillates during walking, the joints of the kneepad are constantly stressed. These joints are generally in a position such that the knee brace offers a significant resistance to the rotation of the upper of the shoe towards the rear.

On connaît d'autre part des chaussure équipée d'un dispositif de blocage de la tige constitué d'une bascule coopérant avec une butée (brevet CH-A 644 501/EP-A 0 086 908). Ce dispositif présente l'avantage de se verrouiller automatiquement sous l'action d'un ressort lorsque le skieur fléchit la jambe. Ce verrouillage peut toutefois se produire inopinément en position de repos ou de marche.On the other hand, shoes are known which are equipped with a device for locking the upper consisting of a rocker cooperating with a stop (patent CH-A 644 501 / EP-A 0 086 908). This device has the advantage of being locked automatically under the action of a spring when the skier bends the leg. This locking may however occur unexpectedly in the rest or on position.

La présente invention a pour but de réaliser un mécanisme de liaison entre la tige et la partie inférieure de la chaussure facile à déverrouiller, se verrouillant automatiquement lors de la flexion de la jambe, et dont la résistance en position de marche est quasiment nulle.The object of the present invention is to provide a connection mechanism between the upper and the lower part of the shoe which is easy to unlock, locking itself automatically when the leg is bent, and the resistance of which in the walking position is almost zero.

A cet effet, la chaussure de ski selon l'invention est caractérisée par le fait que l'une des biellettes présente une lumière ou rainure dans laquelle est engagé l'axe de l'articulation des biellettes entre elles, cette lumière ou rainure présentant une partie longitudinale et une partie transversale, à l'extrémité de la biellette opposée à son point d'articulation sur la chaussure, un moyen élastique, agissant transversalement sur la biellette articulée à la tige et tendant à maintenir l'axe d'articulation des biellettes entre elles dans le fond de la partie transversale de la lumière ou rainure lesdits moyens d'actionnement manuel étant agencés de manière à déplacer angulairement les biellettes relativement l'une à l'autre de manière à dégager l'axe d'articulation de la partie transversale de ladite lumière ou rainure de telle sorte que cet axe puisse vernir coulisser dans la partie longitudinale de la lumière ou rainure.To this end, the ski boot according to the invention is characterized in that one of the links has a lumen or groove in which is engaged the axis of articulation of the links between them, this lumen or groove having a longitudinal part and a transverse part, at the end of the link opposite its point of articulation on the shoe, an elastic means, acting transversely on the link articulated to the upper and tending to maintain the articulation axis of the links between them in the bottom of the transverse part of the light or groove, said manual actuation means being arranged so as to angularly move the rods relatively to one another so as to disengage the axis of articulation from the part transverse of said light or groove so that this axis can varnish slide in the longitudinal part of the light or groove.

La seule résistance à vaincre pour déverrouiller le mécanisme de liaison est celle du moyen élastique. Or ce moyen élastique n'a qu'une fonction de positionnement et il est relativement faible. Lors de la marche, l'axe d'articulation des biellettes entre elles se déplace librement dans la lumière, de telle sorte que la résistance offerte par le mécanisme et pratiquement nulle. Le moyen élastique assure en outre un verrouillage automatique du mécanisme de liaison lorsque le skieur fléchit la jambe.The only resistance to overcome to unlock the link mechanism is that of the elastic means. However, this elastic means has only a positioning function and it is relatively weak. When walking, the articulation axis of the links between them moves freely in the lumen, so that the resistance offered by the mechanism is practically zero. The elastic means also provides automatic locking of the connecting mechanism when the skier bends the leg.

Le mécanisme de liaison peut en outre être aisément muni d'un organe de maintien en position déverrouillée de manière à empêcher un verrouillage automatique intempestif du mécanisme.The connecting mechanism can also be easily provided with a member for holding in the unlocked position so as to prevent inadvertent automatic locking of the mechanism.

Le déverrouillage du mécanisme de liaison peut se faire par pression ou par traction, la seconde solution étant préférable pour éviter un déverrouillage dû à un choc extérieur.The unlocking of the connecting mechanism can be done by pressure or by pulling, the second solution being preferable to avoid unlocking due to an external shock.

La biellette articulée à la tige peut être soit la biellette munie de la lumière ou rainure soit l'autre biellette.The link articulated to the rod can be either the link provided with the light or groove or the other link.

La biellette non munie d'une lumière peut être élastiquement extensible de manière à assurer une élasticité de la tige en flexion.The rod not provided with a light can be elastically extensible so as to ensure an elasticity of the rod in bending.

La chaussure partiellement représentée au dessin est constituée d'une coque inférieure 1 comprenant la semelle 2 et entourant le pied et le talon 3. Sur cette coque est articulée une tige en deux parties comportant une partie antérieure non représentée et une partie postérieure 4 articulée en 5 sur la coque 1. Comme ceci est visible à la figure 5, cette partie postérieure peut basculer relativement loin en arrière grâce à une conformation particulière de la coque dans la région du talon. La chaussure représentée est du type dit à chaussage par l'arrière. La partie avant de la tige peut être articulée autour du même axe 5 qui correspond le mieux possible à l'articulation de la cheville ou autour d'un autre axe. La tige pourrait également être d'une seule pièce.The shoe partially shown in the drawing consists of a lower shell 1 comprising the sole 2 and surrounding the foot and the heel 3. On this shell is articulated a rod in two parts comprising a front part not shown and a rear part 4 articulated in 5 on the shell 1. As can be seen in FIG. 5, this rear part can tilt relatively far back thanks to a particular conformation of the shell in the region of the heel. The shoe shown is of the so-called rear shoe type. The front part of the rod can be articulated around the same axis 5 which corresponds as best as possible to the articulation of the ankle or around another axis. The rod could also be in one piece.

La chaussure représentée comporte à l'arrière un mécanisme de liaison entre la coque inférieure et la tige 4. Ce mécanisme de liaision est constitué essentiellement de deux biellettes 7 et 8 articulées entre elles autour d'un axe 9, la biellette 7 étant en outre articulée à la coque autour d'un axe 10 et la biellette 8 étant articulée à la tige autour d'un axe 11. L'axe 10 est monté entre deux nervures intérieures 12 prévue dans la coque 1. Ces nervures 12 servent également, par leurs profils, à limiter le volume intérieur de la coque destiné à recevoir le talon du skieur. Quant à l'axe 11 de l'articulation de la biellette supérieure 8 à la tige, il est monté entre les deux ailes parallèles 13 et 14 d'un support métallique 15 constitué par un profilé en U encastré dans un logement de même profil formé dans la partie postérieure 4 de la tige comme représenté à la figure 2, le support 15 étant fixé au fond de ce logement par deux rivets 18 indiqués par leurs axes. Les ailes 13 et 14 du support 15 présentent en outre deux rainures longitudinales 16 et 17, identiques et opposées dans lesquelles sont guidées les extrémités de l'axe 9 de l'articulation des biellettes entre elles.The shoe shown has at the rear a connection mechanism between the lower shell and the rod 4. This connection mechanism consists essentially of two links 7 and 8 hinged together around an axis 9, the link 7 being further articulated to the shell around an axis 10 and the link 8 being articulated at the rod around an axis 11. The axis 10 is mounted between two interior ribs 12 provided in the shell 1. These ribs 12 also serve, by their profiles, to limit the interior volume of the shell intended to receive the heel of the skier. As for the axis 11 of the articulation of the upper link 8 to the rod, it is mounted between the two parallel wings 13 and 14 of a metal support 15 constituted by a U-profile embedded in a housing of the same profile formed in the rear part 4 of the rod as shown in Figure 2, the support 15 being fixed to the bottom of this housing by two rivets 18 indicated by their axes. The wings 13 and 14 of the support 15 also have two identical and opposite longitudinal grooves 16 and 17 in which the ends of the axis 9 of the articulation of the links are guided.

La biellette supérieure 8 est également constituée d'une pièce métallique présentant un profil en U (figure 2). Cette biellette 8 est articulée entre les ailes 13 et 14 du support 15 et ses ailes sont munies de deux lumières 19 et 20 opposées et identiques, chacune de ces lumières présentant une partie longitudinale 19a, respectivement 20a et une partie transversale 19b, respectivement 20b formant un angle légèrement inférieur à 90° avec la partie longitudinale. Ces parties transversales 19b et 20b constituent des encoches de verrouillage comme ceci sera décrit plus loin. La biellette 8 est en outre munie de deux bras coudés 21 et 22 traversant le support 15 à travers deux découpes 23 et 24 et une pattelette 25 servant de support et de guidage à un ressort hélicoïdal 26 travaillant en compression entre la biellette 8 et le support 15. Entre l'extrémité des bras 21 et 22 est articulé un levier-came 27 au moyen d'un axe 28. La biellette inférieure 7 est constituée d'une cage rectangulaire 29 formée par découpage et pliage dont les extrémités sont appliquées l'une contre l'autre de manière à former une pattelette 30 par laquelle la biellette est articulée à la coque, et d'une tige 31 traversant un cylindre 32 en élastomère, cette tige étant munie à une extrémité d'une tête 33 recevant l'axe d'articulation 9 et à son autre extrémité d'une rondelle 34, le cylindre en élastomère 32 étant d'une longueur telle qu'à l'état non comprimé ou peu comprimé entre la rondelle 34 et le haut de la cage 29, la tête 33 est en appui contre l'extrémité de la cage 29. La biellette 7 est donc élastiquement extensible mais non compressible. Le fonctionnement du mécanisme de liaison décrit ci- dessus est le suivant :The upper link 8 also consists of a metal part having a U-shaped profile (Figure 2). This link 8 is articulated between the wings 13 and 14 of the support 15 and its wings are provided with two opposite and identical openings 19 and 20, each of these openings having a longitudinal part 19a, respectively 20a and a transverse part 19b, respectively 20b forming an angle slightly less than 90 ° with the longitudinal part. These transverse parts 19b and 20b constitute locking notches as will be described later. The link 8 is further provided with two bent arms 21 and 22 passing through the support 15 through two cutouts 23 and 24 and a plate 25 serving as support and guidance for a helical spring 26 working in compression between the link 8 and the support 15. Between the end of the arms 21 and 22 is articulated a cam lever 27 by means of an axis 28. The lower link 7 consists of a rectangular cage 29 formed by cutting and folding, the ends of which are applied to the one against the other so as to form a plate 30 by which the link is articulated to the shell, and a rod 31 passing through an elastomer cylinder 32, this rod being provided at one end with a head 33 receiving the hinge pin 9 and at its other end of a washer 34, the elastomer cylinder 32 being of a length such that in the uncompressed or slightly compressed state between the washer 34 and the top of the cage 29, the head 33 bears against the end of the cage 29. The rod lette 7 is therefore elastically extensible but not compressible. The operation of the link mechanism described above is as follows:

En position pour la pratique du ski selon la figure 1, le levier-came 27 est rabattu contre le tige 4 et le ressort 26 maintient la biellette 8 écartée du support 15. L'axe 9 d'articulation des biellettes entre elles, retenues latéralement par les rainures de guidage 16 et 17, est au fond des encoches de verrouillage 19b et 20b. La tige 4 est par conséquent verrouillée dans la position représentée à la figure 1. Toutefois, en raison de l'élasticité de la biellette 7, la tige de la chaussure peut légèrement fléchir élastiquement vers l'avant, de manière à assurer confort et sécurité au skieur.In position for skiing according to Figure 1, the cam lever 27 is folded against the rod 4 and the spring 26 keeps the link 8 away from the support 15. The axis 9 of articulation of the links between them, retained laterally by the guide grooves 16 and 17, is at the bottom of the locking notches 19b and 20b. The upper 4 is therefore locked in the position shown in FIG. 1. However, due to the elasticity of the link 7, the upper of the shoe can bend slightly elastically forward, so as to ensure comfort and safety to the skier.

Pour passer dans la position de repos ou de marche, le levier-came 27 est rabattu vers le bas comme représenté à la figure 4. La partie came 27a de ce levier-came prend appui sur le support 15 et a pour effet d'exercer une traction sur les bras 21 et 22 de la biellette 8 qui vient se placer sensiblement parallèlement au support 15 en comprimant le ressort 26 de telle sorte que les parties longitudinales 19a et 20a des lumières de la biellette 8 viennent coïncider avec les rainures de guidage 16 et 17 du support 15. L'axe 9 peut dès lors coulisser dans les guidages 16 et 17 et la tige 4 peut osciller librement autour de son articulation 5 le levier-came 27 restant dans la position représentée à la figure 5. Pour chausser, la partie postérieure de la tige 4, respectivement la tige 4, est basculée en arrière, la longueur des lumières et des rainures de guidages étant prévue assez longue pour permettre un basculement maximum. Le levier-came 27 est ensuite rabattu contre la tige 4, dans la position qu'il occupe à la figure 1. Ce rabattement du levier-came 27 peut déjà être effectué dans la position de la tige représentée à la figure 4, la biellette 8 étant retenue angulairement par l'axe 9 arrive en face des encoches de verrouillage 19b et 20b et le ressort 26 peut alors ramener automatiquement le biellette 8 dans la position verrouillée représentée à la figure 1.To pass into the rest or on position, the cam lever 27 is folded down as shown in FIG. 4. The cam part 27a of this cam lever is supported on the support 15 and has the effect of exerting a pull on the arms 21 and 22 of the link 8 which is placed substantially parallel to the support 15 by compressing the spring 26 so that the longitudinal parts 19a and 20a of the openings of the link 8 coincide with the guide grooves 16 and 17 of the support 15. The axis 9 can therefore slide in the guides 16 and 17 and the rod 4 can oscillate freely around its articulation 5 the cam lever 27 remaining in the position shown in FIG. 5. the rear part of the rod 4, respectively the rod 4, is tilted back, the length of the lights and the guide grooves being provided long enough to allow maximum tilting. The cam lever 27 is then folded back against the rod 4, in the position it occupies in FIG. 1. This folding of the cam lever 27 can already be carried out in the position of the rod shown in FIG. 4, the connecting rod 8 being retained angularly by the axis 9 arrives opposite the locking notches 19b and 20b and the spring 26 can then automatically return the rod 8 to the locked position shown in FIG. 1.

Le biellette extensible 7 pourrait bien entendu être remplacée par une biellette rigide si l'on se contente de la déformation élastique de la chaussure pour assurer son élasticité en flexion.The extendable link 7 could of course be replaced by a rigid link if one is satisfied with the elastic deformation of the shoe to ensure its elasticity in flexion.

Selon une autre variante d'exécution, les encoches de verrouillage pourraient être orientées en direction de l'intérieur de la chaussure; le ressort 26 serait alors disposé de l'autre côté de la biellette 8. Dans ce cas le déverrouillage du mécanisme de liaison s'effectuerait par pression sur la biellette 8, soit au moyen d'un came qui maintiendrait la biellette 8 en position déverrouillée soit sans came, ce qui aurait toutefois pour inconvénient que le mécanisme pourrait se verrouiller intempestivement lors d'une flexion de la jambe.According to another alternative embodiment, the locking notches could be oriented towards the interior of the shoe; the spring 26 would then be disposed on the other side of the link 8. In this case, the unlocking of the connection mechanism would be effected by pressure on the link 8, either by means of a cam which would hold the link 8 in the unlocked position. either without cam, which would however have the disadvantage that the mechanism could lock unexpectedly during a bending of the leg.

Selon une autre variante les biellettes 7 et 8 pourraient être interverties, la biellette extensible 7 étant alors articulée sur la tige 4 de la chaussure. Dans ce cas, le déverrouillage pourrait s'effectuer également soit par traction soit par pression sur la biellette supérieure, selon l'orientation des encoches de verrouillage.According to another variant, the links 7 and 8 could be inverted, the extendable link 7 then being articulated on the upper 4 of the shoe. In this case, the unlocking could also be carried out either by traction or by pressure on the upper link, depending on the orientation of the locking notches.

Claims (5)

1. Ski boot made of at least semi-rigid material and consisting of a bottom part (1) comprising the sole and surrounding the foot and the heel and of an upper (4) hinged with the bottom part and comprising, at the rear, a connecting mechanism comprising essentially two links (7, 8) hinged with each other and with the upper and the bottom part of the boot, respectively, the mechanism being arranged in such a way that it is able to assume a first position where the upper is locked relative to the bottom part and a second position where the upper is free to pivot on the bottom part, one of the links being provided with manual operating means, characterized by the fact that one of the links has an aperture or groove (19) inside which the pin (9) hingeably connecting the links together is engaged, this aperture or groove having a longitudinal part (19a) and a transverse part (19b) at the opposite end to the point (11) where it is hinged with the boot (11), the connecting mechanism comprising in addition an elastic means (26) acting transversely on the link hinged with the upper and tending to keep the pin (9) hingeably connecting the links together inside the bottom of the transverse part (19b) of the aperture or groove, the said manual operating means (27) being arranged in such a way as to move the links angularly relative to each other so as to disengage the hinging pin (9) from the transverse part of the said aperture or groove, in such a way that this pin is able to slide inside the longitudinal part of the aperture (19a).
2. Boot according to claim 1, characterized by the fact that the link without an aperture or groove (7) is elastically extendable.
