Abstract
Description
L'invention concerne un dispositif de fermeture d'une chaussure, notamment d'une chaussure de ski.The invention relates to a device for closing a boot, in particular a ski boot.
De façon connue, de tels dispositifs sont utilisés pour resserrer deux pans ou deux rabats d'une coque autour d'un chausson dans lequel se trouve le pied du skieur.In known manner, such devices are used to tighten two flaps or two flaps of a shell around a liner in which the skier's foot is located.
L'invention se rapporte aux dispositifs de fermeture qui mettent en oeuvre un levier de manoeuvre à genouillère d'une part, et une crémaillère d'autre part, qui permet de réaliser un réglage au moins grossier de la longueur du dispositif.The invention relates to closing devices which use an operating lever toggle on the one hand, and a rack on the other hand, which allows for adjustment at least rough the length of the device.
Egalement de manière connue, de tels dispositifs comportent des moyens de réglage complémentaires de la position de la crémaillère par rapport au lever, permettant d'augmenter sa capacité de serrage s'ajoutant à celle obtenue classiquement par le choix d'une dent ou d'une autre avec laquelle est susceptible de coopérer un organe d'accrochage, lui-même relié au levier de manoeuvre.Also in known manner, such devices include adjustment means. complementary to the position of the rack relative to the lift, allowing to increase its clamping capacity added to that conventionally obtained by the choice of one tooth or another with which is capable of cooperating a fastening member, itself connected to the lever maneuver.
Le brevet européen n° 545 965 WO-A-92/03071 décrit un dispositif de fermeture du type précité dans lequel l'on obtient un réglage complémentaire de la position de la crémaillère par l'intermédiaire d'une excentrique dont l'axe peut être déplacé dans un sens longitudinal et dans le sens transversal d'un organe de traction, ledit excentrique étant lié par ailleurs à un élément cranté pouvant être bloqué ou libéré par un organe de serrage.European patent no. 545,965 WO-A-92/03071 describes a closure device of the aforementioned type in which one obtains an additional adjustment of the rack position via an eccentric the axis of which can be moved in a longitudinal direction and in the transverse direction of a traction, said eccentric being linked moreover to a notched element which can be blocked or released by a clamping member.
Ce dispositif présente l'inconvénient majeur de devoir desserrer un organe, une vis par exemple, avant d'effectuer le retournement de l'excentrique. De plus, cela implique de disposer d'un outil approprié qui s'ajoute à la contrainte de l'intervention s'effectuant selon un temps plus ou moins long. Par ailleurs, un tel système implique de devoir aligner les crans de l'excentrique avant resserrage de l'ensemble.This device has the major drawback of having to loosen an organ, a screw for example, before turning the eccentric. In addition, this implies having a tool appropriate which is added to the constraint of the intervention being carried out according to a more or less long time. In addition, such a system implies having to align the notches of the eccentric before tightening of all.
Le certificat d'utilité français n° 2 561 503 décrit en ce qui le concerne un dispositif de réglage de crans situés à sa partie inférieure et coopérant avec un moyen d'arrêt agissant dans le sens de la traction d'un tirant auquel elle est reliée, le maintien dans une position choisie s'effectuant grâce à un moyen de poussée élastique. Un tel système est non seulement très coûteux par le nombre de pièces à mettre en oeuvre mais présente également l'inconvénient d'être peu fiable du fait que les chocs qu'il est susceptible de recevoir dans une zone aussi exposée peuvent conduire à une désolidarisation de la crémaillère par rapport à ses moyens d'immobilisation et de réglage.French utility certificate no. 2,561,503 describes, as far as it is concerned, a device for adjusting the notches located at its lower part and cooperating with a stop means acting in the direction of the pulling a tie rod to which it is connected, maintaining in a chosen position by means of a elastic pushing means. Such a system is not only very expensive by the number of parts to be implement but also has the disadvantage of being unreliable because the shocks it is likely to receive in such an exposed area can lead to separation of the rack relative to its immobilization and adjustment means.
Le brevet d'invention français n° 2 109 080 enseigne d'effectuer un réglage complémentaire dans un dispositif de fermeture, mais à la différence des précédents, la crémaillère est portée par le levier de manoeuvre lui-même, et les moyens de réglage complémentaires sont réalisés sur une embase d'un étrier d'accrochage au niveau de sa fixation sur l'autre pan de la chaussure. Dans ce cas, le réglage du serrage s'effectue sur chaque pan de la chaussure et nécessite de désolidariser l'étrier d'accrochage de la crémaillère du lever pour permettre son réglage complémentaire, ce qui implique de larges mouvements de la part de l'utilisateur, pas toujours aisés à effectuer.French patent No. 2 109 080 teaches to carry out an additional adjustment in a closing device, but unlike the previous ones, the rack is carried by the lever maneuver itself, and the additional adjustment means are produced on a base of a hooking bracket at its attachment to the other side of the shoe. In this case, the setting tightening is carried out on each side of the shoe and requires detaching the stirrup hooking the lever rack to allow its additional adjustment, which involves large movements by the user, not always easy to perform.
La présente invention a pour objectif de remédier aux différents inconvénients ressortant des dispositifs connus cités ci-dessus, en prévoyant notamment un double réglage du serrage sur une seule pièce montée sur un pan de la chaussure. The object of the present invention is to remedy the various drawbacks arising from known devices mentioned above, in particular providing for a double adjustment of the tightening on a single piece mounted on a side of the shoe.
A cet effet, elle concerne un dispositif de fermeture d'une chaussure, notamment d'une chaussure de ski, destiné à maintenir rapproché deux pans de la chaussure et comprend d'une part, un levier de manoeuvre porté par une platine reliée solidairement à l'un des pans à rapprocher de l'autre, et d'autre part, sur l'autre pan une crémaillère comportant des moyens de réglage complémentaires de sa position par rapport au levier permettant d'augmenter sa capacité de serrage, crémaillère dans l'une des dents de laquelle est susceptible de s'engager un organe d'accrochage, lui-même relié au levier de manoeuvre par un tirant inextensible caractérisé en ce que les moyens de réglage de la crémaillère sont constitués par une zone de réglage comportant une lumière oblongue en forme de boutonnière réalisée sur le pan de la chaussure au droit d'une face inférieure de la crémaillère et délimitée par deux zones d'extrémité circulaires dont le diamètre est égal à celui d'un pion de verrouillage solidaire de la face inférieure de la crémaillère et traversant ladite boutonnière pour y être retenu axialement, lesdites zones circulaires étant reliées entre elles par une partie droite à bords parallèles, écartés l'un de l'autre selon une valeur égale à celle d'une partie méplate du pion de la crémaillère qui est réalisée dans un sens perpendiculaire à l'axe longitudinal de déplacement de cette dernière, de manière à ce que celle-ci puisse être déplacée, en vue de son réglage, d'une extrémité à l'autre de la boutonnière, après une rotation à 90° par rapport à son axe longitudinal pour permettre le libre coulissement de la zone méplate du pion d'où celui de la crémaillère dans l'une ou l'autre des zones circulaires d'extrémité, par une rotation de 90° en sens inverse, ramenant la crémaillère dans une position longitudinale fonctionnelle.To this end, it relates to a device for closing a shoe, in particular a shoe ski, intended to keep two sections of the boot close together and comprises, on the one hand, a lever for maneuver carried by a plate connected integrally to one side to be brought closer to the other, and other share, on the other side, a rack comprising means for complementary adjustment of its position relative to the lever to increase its clamping capacity, rack in one teeth from which is capable of engaging a fastening member, itself connected to the lever operation by an inextensible tie rod characterized in that the means for adjusting the rack consist of an adjustment zone comprising an oblong buttonhole-shaped light produced on the side of the shoe in line with a lower face of the rack and delimited by two circular end zones whose diameter is equal to that of a locking pin integral with the underside of the rack and passing through said buttonhole to be retained there axially, said circular zones being interconnected by a straight part with parallel edges, one apart on the other according to a value equal to that of a flat part of the rack pin which is made in a direction perpendicular to the longitudinal axis of displacement of the latter, so that it can be moved, for adjustment, from one end to the other of the buttonhole, after 90 ° rotation with respect to its longitudinal axis to allow the area to slide freely flat of the pin, hence that of the rack in one or other of the circular end zones, by a 90 ° rotation in opposite direction, bringing the rack into a longitudinal position functional.
La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the characteristics which will emerge during the description which will follow, and which should be considered in isolation or in all their combinations possible techniques.

Selon le mode d'exécution représenté sur les figures, le dispositif de fermeture 1 globalement
désigné, est destiné à assurer le rapprochement de deux pans de chaussure 2 et 3.According to the embodiment shown in the figures, the
Le dispositif 1 comprend, dans cet exemple, un lever de manoeuvre 4 de type à genouillère. Un tel
levier 4 est connu et comprend un bras 5 relié au pan 3 de la chaussure par l'intermédiaire d'une
platine 6. Un tirant inextensible 7 est fixé de manière articulé sur le bras 5 du lever 4, et est destiné à
être relié à une crémaillère 8 par l'intermédiaire d'un organe d'accrochage inextensible 9 apte à
coopérer avec au moins l'une des dents 8a, 8b, 8c,..., de celle-ci.The
La crémaillère 8 est fixée sur le pan 2 de la chaussure alors que le levier 4 est fixé sur l'autre pan
3 à rapprocher.The
La crémaillère 8 comporte des moyens de réglage complémentaires de sa position par rapport au
levier 4 afin d'augmenter sa capacité de serrage s'ajoutant à celui obtenu par la coopération de l'une
de ses dents 8a, 8b, 8c,..., avec l'organe d'accrochage 9.The
Selon l'invention, ces moyens de réglage sont constitués d'une manière générale par une lumière
oblongue en forme de boutonnière 10 réalisée dans une zone de réglage du pan 2 de la chaussure au
droit d'une face inférieure de la crémaillère 8 et délimitée par deux zones d'extrémité circulaires 11, 12,
dont les diamètres respectivement D1, D2, sont identiques et égaux à celui d'un pion de verrouillage 13
solidaire de la face inférieure de la crémaillère 8. Le pion 13 traverse ladite boutonnière 10 pour y être
retenu axialement. Les zones circulaires 11, 12, et la boutonnière 10 sont reliées entre elles par une
partie droite 14 à bords parallèles 15 et 16, écartés l'un de l'autre selon une valeur B égale à celle B'
d'une partie méplate 17 du pion 13 de la crémaillère 8 qui est orientée dans un sens perpendiculaire
Y-Y' à l'axe longitudinal X-X' de déplacement de cette dernière lorsqu'elle est verrouillée. De cette
manière, ladite crémaillère 8 peut être déplacée selon F, en vue de son réglage, d'une extrémité 11 à
l'autre 12 de la boutonnière 10, après une rotation R à 90° par rapport à son axe longitudinal X-X'
pour
permettre le libre coulissement de la zone méplate 17 du pion 13 dans la partie droite 14 de la
boutonnière 10 et le verrouillage de ce dernier 13 d'où celui de la crémaillère 8 dans l'une ou l'autre des
zones circulaires d'extrémité 11 et 12, par une rotation de 90° en sens inverse, ramenant la
crémaillère 8 dans une position longitudinale fonctionnelle.According to the invention, these adjustment means generally consist of a light
De cette manière, et comme le montre particulièrement bien la figure 5, la crémaillère 8 pourra être
placée dans une position P1 ou P2 différente selon une valeur de déplacement X.In this way, and as shown particularly well in FIG. 5, the
Un avantage particulièrement intéressant de l'invention réside dans le fait qu'une fois réglée, la
crémaillère 8 peut se débattre angulairement par rapport à l'axe longitudinal de son support, lui
permettant ainsi un auto-alignement avec le levier de manoeuvre 4 lorsque les pans 2 et 3 se
déforment lors de la manoeuvre de serrage, ou lors de la pratique du ski, en fonction des mouvements
du pied du skieur et des déformations éventuelles de la coque de la chaussure.A particularly advantageous advantage of the invention resides in the fact that once adjusted, the
De manière à renforcer la zone de réglage sur laquelle est réalisée la boutonnière 8, celle-ci
est
constituée par un surmoulage d'une matière plastique relativement rigide effectuée sur le pan 2
concerné de la chaussure.In order to reinforce the adjustment zone on which the
Selon l'exemple de réalisation représenté sur les figures 1 et 2, la zone de réglage sur laquelle est
réalisée la boutonnière 10 est constituée par une plaque support rigide 20 relativement plane sur
laquelle est préalablement fixée la crémaillère 8 de manière coulissante, et qui est rapportée sur le pan
2 de la chaussure par l'intermédiaire de deux rivets de fixation 21 et 22 à ses extrémités, ledit pan 2
de la chaussure étant lui-même muni d'une ouverture 23 le traversant sur toute son épaisseur et apte
à permettre le libre débattement du pion 13 de la crémaillère 8 lors d'un réglage ultérieur.According to the embodiment shown in Figures 1 and 2, the adjustment area on which is
made the
Selon l'exemple de la figure 3, la zone de réglage sur laquelle est réalisée la boutonnière 8 est
constituée par une plaque support rigide 24 en forme d'oméga dont une partie centrale de profil en U
renversé est destinée à se loger dans une ouverture transversale 25 du pan 2A de la chaussure, une
partie relativement plane supérieure 26 constituant la branche horizontale du U comporte la
boutonnière 10 dans laquelle est préalablement fixée de manière coulissante la crémaillère 8, et
effleure la surface extérieure du pan 2A de la chaussure. Les branches latérales 27 et 28 de l'oméga
s'étendant dans des directions opposées se logent dans des évidements 29 et 30 réalisés sur la
surface interne du pan 2A de la chaussure et reçoivent deux rivets de fixation 31 et 32 le traversant
de part en part.According to the example of FIG. 3, the adjustment zone on which the
Selon l'exemple de la figure 4, la zone de réglage sur laquelle est réalisée la boutonnière 10 est
constituée par une plaque support rigide 33 relativement plane sur laquelle est préalablement fixée la
crémaillère 8 de manière coulissante, et qui est rapportée dans un logement 34 de forme et d'épaisseur
correspondantes réalisé sur la surface extérieure du pan 2B de la chaussure pour y être fixé par
l'intermédiaire de deux rivets 35 et 36 à ses extrémités, ledit pan 2B comportant au droit de la
boutonnière 10 un logement borgne 37 de dimensions aptes à permettre le libre débattement du pion 13
porté par la crémaillère 8 lors d'un réglage ultérieur de celle-ci.According to the example of FIG. 4, the adjustment zone on which the
Ce mode de réalisation offre de nombreux avantages, à savoir :
- le pan 2B n'est pas ouvert de part en part, donc moins de risque de fragilisation, de déformation au serrage et de manque d'étanchéité,
- aucune partie visible à l'intérieur de la chaussure hormis les rivets de
fixation 35 et 36, - la
plaque support 33 est particulièrement simple, - possibilité d'un montage séparé d'un sous-ensemble complet.
- the pan 2B is not open right through, therefore less risk of embrittlement, deformation when tightened and lack of tightness,
- no visible part inside the shoe except the fastening
rivets - the
support plate 33 is particularly simple, - possibility of separate mounting of a complete sub-assembly.
Selon l'exemple des figures 1 à 4, la retenue axiale du pion de verrouillage 13 et de la crémaillère 8
sur le pan 2 de la chaussure dans la zone de réglage s'effectue par l'intermédiaire d'une zone circulaire
élargie 38 dudit pion 13 prenant appui sous la boutonnière de réglage 10, et dont les dimensions D3 sont
au moins supérieures à celles D1, D2, des zones circulaires d'extrémité 11 et 12 de cette demière.According to the example of FIGS. 1 to 4, the axial retention of the
Dans ce cas, le pion 13 est obtenu distinctement de la crémaillère 8 et forme à sa base une
collerette constituant la zone d'appui élargie 38. La liaison d'un tel pion 13 sur la crémaillère 8, de
manière coulissante, s'effectue par l'intermédiaire d'un axe perpendiculaire 39 issu de la face inférieure
