Definitions

  • the present invention relates to a ski boot comprising a shell of rigid material consisting of a lower part comprising the sole and surrounding the foot and at least one upper part articulated on the lower part around a transverse axis of such so that it can tilt forwards, an elastic member being arranged between said articulated upper part and said lower part of the shell so as to offer an elastic resistance to the inclination of the upper part towards the 'before.
  • the present invention aims to achieve a shoe comprising at the front an elastic resistance to adjustable flexion, produced by simple means and of small size, in particular not comprising a helical spring.
  • the ski boot according to the invention is characterized in that the elastic member consists of at least one elongated part working in buckling and that adjustment means are provided for modifying the length of the part working in buckling of the elastic piece.
  • the elongated elastic piece can be as well of elastomer, as of metal or in mineral material such as fiberglass or carbon.
  • the modification of the length of the part working in buckling can be done simply by means of a cursor acting directly on the elastic member in order to limit more or less the length of the part working in buckling.
  • the ski boot shown in Figure 1 comprises a semi-rigid plastic shell consisting of a lower part 1 comprising the sole and surrounding the foot and the heel and of two upper parts 2 and 3 articulated on the lower part 1 around about a transverse axis 4 at the level of the articulation of the foot.
  • These parts 2 and 3 are of approximately semi-cylindrical shape and fit into one another to surround the ankle of the skier. They are kept closed by a loop 5 of known type.
  • the rear articulated part 3 can be tilted back so as to allow the shoe to be put on. Inside the shoe is disposed a bootie 6 of compressible and soft material.
  • the upper parts 2 and 3 being articulated on the lower part 1, they can tilt forward when skiing. Opposed to this inclination is the elastic resistance of an elastic device mounted in a housing 7 fixed to the upper part of the shell 1 or coming in one piece with this part 1.
  • the housing 7 defines a rectangular housing 8 closed by a cover 9.
  • These elastic bars 10 and 11 are supported by one of their ends against a front wall of the housing 8, while on their other ends is supported a pusher 11 transmitting the force of the articulated part 2 of the shell to the elastic bars 10 and 11.

  • the introduction of the stud 13 between the elastic bars 10 and 11 has the effect of preventing part of these bars and buckle, and consequently to increase the buckling resistance of bars 10 and 11.
  • This increase in buckling resistance results in an increase in elastic force opposing the forward pivoting of part 2 of the hull.

  • the elastic member is constituted by a rubber plate 32 of rectangular parallelepiped shape but the lower face of which has a depression 32a creating an axial asymmetry so that the buckling of the bag 32 is always upwards.
  • This plate is mounted in a housing 33 formed in a base 34 attached to the shell 1 or come in one piece with this shell, in the same way as the housing 7.
  • the thrust of the articulated part 2 of the shell is transmitted by a plunger 35 of generally rectangular shape and provided with a rectangular notch 36 in which the elastic plate 32 engages.

At its lower part, the stud 50 has a flexible curved tongue 52, coming in one piece with the stud 50, and pressing, under bending, against the shell 1.

Description

La présente invention a pour objet une chaussure de ski comprenant une coque en matière rigide constituée d'une partie inférieure comprenant la semelle et entourant le pied et d'au moins une partie supérieure articulée sur la partie inférieure autour d'un axe transversal de telle manière qu'elle peut s'incliner vers l'avant, un organe élastique étant disposé entre ladite partie supérieure articulée et la dite partie inférieure de la coque de manière à offri- re une résistance élastique à l'inclinaison de la partie supérieure vers l'avant.The present invention relates to a ski boot comprising a shell of rigid material consisting of a lower part comprising the sole and surrounding the foot and at least one upper part articulated on the lower part around a transverse axis of such so that it can tilt forwards, an elastic member being arranged between said articulated upper part and said lower part of the shell so as to offer an elastic resistance to the inclination of the upper part towards the 'before.

Plusieurs fabricants de chaussures de ski ont mis sur le marché des chaussures de ce type, dans lesquelles l'organe élastique est constitué par un bloc de caoutchouc travaillant à la compression. La résistance élastique de ce bloc de caoutchouc est constante. Or de nombreux skieurs aimeraient avoir la possibilité de modifier la résistance élastique de ce bloc de caoutchouc en fonction de leur manière de skier et/ou des conditions de la neige.Several manufacturers of ski boots have marketed boots of this type, in which the elastic member is constituted by a block of rubber working under compression. The elastic resistance of this rubber block is constant. Many skiers would like to have the possibility of modifying the elastic resistance of this rubber block according to their way of skiing and / or the snow conditions.

Il est certe connu du brevet US 3 619 914 de monter à l'arrière de la chaussure un ressort hélicoïdal dont la dureté peut être réglée au moyen d'un écrou. Toutefois, un tel dispositif à l'arrière ne peut pas être monté sur les chaussures dites à entrée par l'arrière c'est-à-dire les chaussures présentant un capot arrière articulé et basculable vers l'arrière pour ouvrir la chaussure. Un tel dispositif pourrait être monté à l'avant, mais compte tenu de la force nécessaire du ressort, et la longueur nécessaire au réglage, il serait trop encombrant.It is certainly known from US Pat. No. 3,619,914 to mount a helical spring at the rear of the shoe, the hardness of which can be adjusted by means of a nut. However, such a device at the rear cannot be mounted on shoes said to have rear entry, that is to say shoes having a hinged rear cover and tiltable towards the rear to open the shoe. Such a device could be mounted at the front, but taking into account the necessary force of the spring, and the length necessary for the adjustment, it would be too bulky.

La présente invention à pour but de réaliser une chaussure comprenant à l'avant une résistance élastique à la flexion réglable, réalisé par des moyens simples et de faible encombrement, notamment ne comprenant pas de ressort hélicoïdal. La chaussure de ski selon l'invention est caractérisée par le fait que l'organe élastique est constitué d'au moins une pièce allongée travaillant en flambage et que des moyens d'ajustement sont prévus pour modifier la longueur de la partie travaillant en flambage de la pièce élastique.The present invention aims to achieve a shoe comprising at the front an elastic resistance to adjustable flexion, produced by simple means and of small size, in particular not comprising a helical spring. The ski boot according to the invention is characterized in that the elastic member consists of at least one elongated part working in buckling and that adjustment means are provided for modifying the length of the part working in buckling of the elastic piece.

La pièce élastique allongée peut être aussi bien en élastomère, qu'en métal ou en matière minérale telle que de la fibre de verre ou de carbone.The elongated elastic piece can be as well of elastomer, as of metal or in mineral material such as fiberglass or carbon.

La modification de la longueur de la partie travaillant au flambage peut se faire simplement au moyen d'un curseur agissant directement sur l'organe élastique afin de limiter plus ou moins la longueur de la partie travaillant en flambage.The modification of the length of the part working in buckling can be done simply by means of a cursor acting directly on the elastic member in order to limit more or less the length of the part working in buckling.

La chaussure de ski représentée à la figure 1 comprend une coque en matière plastique semi-rigide constituée d'une partie inférieure 1 comprenant la semelle et entourant le pied et le talon et de deux parties supérieures 2 et 3 articulées sur la partie inférieure 1 autour d'un axe transversal 4 environ au niveau de l'articulation du pied. Ces parties 2 et 3 sont de forme approximativement semi-cylindrique et s'emboîtent l'une dans l'autre pour entourer la cheville du skieur. Elles sont maintenues fermées par une boucle 5 de type connu. La partie articulée postérieure 3 peut être basculée en arrière de manière à permettre le chaussage de la chaussure. A l'intérieur de la chaussure est disposé un chausson 6 en matière compressible et moelleuse. Les parties supérieures 2 et 3 étant articulées sur la partie inférieure 1, elles peuvent s'incliner vers l'avant lors de pratique du ski. A cette inclinaison s'oppose la résistance élastique d'un dispositif élastique monté dans un boîtier 7 fixé sur la partie supérieure de la coque 1 ou venue d'une pièce avec cette partie 1.The ski boot shown in Figure 1 comprises a semi-rigid plastic shell consisting of a lower part 1 comprising the sole and surrounding the foot and the heel and of two upper parts 2 and 3 articulated on the lower part 1 around about a transverse axis 4 at the level of the articulation of the foot. These parts 2 and 3 are of approximately semi-cylindrical shape and fit into one another to surround the ankle of the skier. They are kept closed by a loop 5 of known type. The rear articulated part 3 can be tilted back so as to allow the shoe to be put on. Inside the shoe is disposed a bootie 6 of compressible and soft material. The upper parts 2 and 3 being articulated on the lower part 1, they can tilt forward when skiing. Opposed to this inclination is the elastic resistance of an elastic device mounted in a housing 7 fixed to the upper part of the shell 1 or coming in one piece with this part 1.

Ce dispositif élastique sera décrit en détail au moyen de la figure 2. Le boîtier 7 définit un logement rectangulaire 8 fermé par un couvercle 9. Dans ce logement sont disposées deux barres 10 et 11 en élastomère, par exemple en caoutchouc, de forme parallélépipédique rectangulaire et orientées dans le sens du pied. Ces barres élastiques 10 et 11 s'appuient par une de leurs extrémités contre une paroi frontale du logement 8, tandis que sur leurs autres extrémités s'appuie un poussoir 11 transmettant la force de la partie articulée 2 de la coque aux barres élastiques 10 et 11. Ce poussoir 12 présente une face frontale 12a parallèle à la surface d'appui 13 du bord inférieur de la partie articulée 2 de la coque. Le poussoir 12 présente en outre une partie médiane saillante 12b s'engageant entre les barres élastiques 10 et 11 et une partie médiane saillante opposée 12c s'engageant dans la partie 2 de la coque pour la retenue latérale du poussoir. Les côtés extérieurs des barres élastiques 10 et 11 présentent une dépression 10a respectivement 11 a qui crée une asymétrie relativement à l'axe des barres, de telle sorte que lorsqu'on exerce une pression axiale sur ces barres au moyen du poussoir 12, les barres élastiques 10 et 11 ont tendance à flamber toujours dans la même direction, c'est-à-dire vers l'intérieur du logement 8. Dans la position représentée à la figure 2, les barres élastiques 10 et 11 ont la possibilité de flamber sur toute leur longueur. Il est toutefois possible de modifier la longueur susceptible de flamber, au moyen d'un plot rigide 13, de préférence en matière plastique, logé dans un prolongement axial du logement 8. Ce plot 13 est solidaire d'une tige filetée 14 fixe en rotation, sur laquelle est monté un écrou 15 en forme de molette disposé dans un logement ouvert dans lequel elle est retenue axialement, mais peut tourner librement. La molette 15 fait légèrement saillie sur la chaussure comme représenté à la figure 1, de manière à pouvoir être actionnée par le skieur. Son actionnement permet de déplacer le plot 13 dans le sens de la flêche F1 pour l'amener entre les barres élastiques 10 et 11 avec un léger jeu. L'introduction du plot 13 entre les barres élastiques 10 et 11 a pour effet d'empêcher une partie de ces barres et flamber, et par conséquent d'augmenter la résistance au flambage des barres 10 et 11. Cette augmentation de la résistance au flambage ce traduit par une augmentation de la force élastique s'opposant au pivotement vers l'avant de la partie 2 de la coque. Le plot 13 constitue donc un curseur permettant de régler de façon simple et fine la résistance élastique de l'organe élastique s'opposant à la fexion de la jambe du skieur.This elastic device will be described in detail by means of Figure 2. The housing 7 defines a rectangular housing 8 closed by a cover 9. In this housing are arranged two bars 10 and 11 of elastomer, for example rubber, of rectangular parallelepiped shape and oriented in the direction of the foot. These elastic bars 10 and 11 are supported by one of their ends against a front wall of the housing 8, while on their other ends is supported a pusher 11 transmitting the force of the articulated part 2 of the shell to the elastic bars 10 and 11. This pusher 12 has a front face 12a parallel to the bearing surface 13 of the lower edge of the articulated part 2 of the shell. The pusher 12 also has a protruding middle part 12b engaging between the elastic bars 10 and 11 and an opposite protruding middle part 12c engaging in the part 2 of the shell for lateral retention of the pusher. The outer sides of the elastic bars 10 and 11 have a depression 10a respectively 11 a which creates an asymmetry relative to the axis of the bars, so that when an axial pressure is exerted on these bars by means of the pusher 12, the bars elastic 10 and 11 tend to flame always in the same direction, that is to say towards the inside of the housing 8. In the position shown in FIG. 2, the elastic bars 10 and 11 have the possibility of flaming on their entire length. It is however possible to modify the length liable to buckle, by means of a rigid stud 13, preferably made of plastic, housed in an axial extension of the lo gement 8. This stud 13 is integral with a threaded rod 14 fixed in rotation, on which is mounted a nut 15 in the form of a wheel disposed in an open housing in which it is retained axially, but can rotate freely. The wheel 15 protrudes slightly from the boot as shown in FIG. 1, so that it can be actuated by the skier. Its actuation makes it possible to move the stud 13 in the direction of the arrow F1 to bring it between the elastic bars 10 and 11 with a slight play. The introduction of the stud 13 between the elastic bars 10 and 11 has the effect of preventing part of these bars and buckle, and consequently to increase the buckling resistance of bars 10 and 11. This increase in buckling resistance results in an increase in elastic force opposing the forward pivoting of part 2 of the hull. The stud 13 therefore constitutes a slider enabling the elastic resistance of the elastic member opposing the attachment of the skier's leg to be adjusted in a simple and fine manner.

Les figures 3, 4 et 5 représentent une variante de curseur permettant un réglage plus rapide. Les pièces identiques ou analogues à la première forme d'exécution sont désignées par les mêmes références que dans la figure 2. Dans cette variante d'exécution le réglage de la longueur des barres 10 et 11 travaillant en flambage s'effectue au moyen d'un plot 16 constitué d'une pièce profilée en U renversé dans laquelle est logée une pièce 17 présentant également un profil en U dirigé dans l'autre sens et muni de 4 tenons verticaux 18, 19, 20 et 21 traversant verticalement et librement 4 trous correspondant 22, 23, 24 et 25 ménagés dans la face supérieure du plot 16. Sur les tenons 18, 19, 20 et 21 est fixée une plaquette 26 constituant un poussoir. Entre la face supérieure 2a du plot 16 et la plaquette 6 est monté un ressort 27 travaillant en compression et ayant donc tendance à tirer la pièce 17 vers le haut contre le fond du profil du plot 16. Le fond du profil en U de la pièce 17 présente une denture 28. La pièce 17 est en outre traversée par une tige longitudinale métallique 29 munie d'une denture, par exemple une simple tige filetée, fixée par l'une de ses extrémités dans l'extrémité inférieure 7a du boîtier 7. L'autre extrémité de la tige filetée 29 s'engage librement dans un passage 30 ménagé dans le poussoir 12. La tige 29 est fixée à un niveau tel que la denture 28 de la pièce 17 est engagée dans la denture de la tige 29 sous l'effet du ressort 27. Le plot 16 est par conséquent immobilisé sur la tige 29. Pour déplacer le plot 16, il suffit de presser sur le poussoir 26, ce qui dégage la pièce 17 de la tige filetée 29 et permet son déplacement rapide tout le long de cette tige 29. Sitôt qu'on relâche la pression sur le poussoir 26, le plot 16 s'immobilise dans sa nouvelle position. Le couvercle 9 présente une fente rectangulaire longitudinale 31 de largeur égale à celle du poussoir 26 pour permettre le déplacement du plot 16. Une autre forme d'exécution de l'organe élastique est représentée aux figures 6 et 7. Dans cette exécution, l'organe élastique est constitué par une plaquette 32 en caoutchouc de forme parallélépipédique rectangulaire mais dont la face inférieure présente une dépression 32a créant une asymétrie axiale de telle sorte que le flambage de la paquette 32 se fait toujours vers le haut. Cette plaquette est montée dans un logement 33 pratiqué dans un socle 34 rapporté sur la coque 1 ou venu d'une pièce avec cette coque, de la même manière que le boîtier 7. La poussée de la partie 2 articulée de la coque est transmise par un poussoir 35 de forme générale rectangulaire et munie d'une encoche rectangulaire 36 dans laquelle s'engage la plaquette élastique 32. Le logement 33 est fermé par un couvercle 37 fixé au socle 34 par tous moyens connus tel que collage, soudage, cran- tage ou au moyen de vis. Ce couvercle 7 présente une fente axiale longitudinale 38 traversée par un curseur 39 dont la partie intérieure présente un élargissement transversale en forme de T s'étendant sous le couvercle 37. Sous la tête du curseur 39 est disposée une plaquette 41 en matière élastique comprimée, qui a tendance à maintenir la partie élargie 40 du curseur contre la paroi intérieure du couvercle 37. Cette partie de la paroi est munie d'une denture 42 coopérant avec des dents 43 prévues sur la partie élargie 40 du curseur. Pour dégager le curseur il suffit d'appuyer sur le curseur qui peut alors être déplacé axialement le long de la fente 38. La plaquette élastique 32 a été représentée en position comprimée. On voit que la partie gauche de la plaquette 32 ne peut pas flamber car elle est retenue par le curseur. En déplaçant le curseur ont peut ainsi faire varier la longueur susceptible de flamber. Selon une variante d'exécution la partie élargie 40 comprime légèrement, au repos, la paquette 32 qui maintient les dents 43 en prise avec les dents 42. La plaquette 32 remplace ainsi la plaquette auxiliaire 41.Figures 3, 4 and 5 show a variant of the slider allowing faster adjustment. The identical or analogous parts to the first embodiment are designated by the same references as in FIG. 2. In this alternative embodiment, the length of the bars 10 and 11 working in buckling is adjusted by means of a stud 16 consisting of an inverted U-shaped piece in which is housed a piece 17 also having a U-shaped profile directed in the other direction and provided with 4 vertical studs 18, 19, 20 and 21 crossing vertically and freely 4 holes corresponding 22, 23, 24 and 25 formed in the upper face of the stud 16. On the pins 18, 19, 20 and 21 is fixed a plate 26 constituting a pusher. Between the upper face 2a of the stud 16 and the plate 6 is mounted a spring 27 working in compression and therefore tending to pull the piece 17 upwards against the bottom of the profile of the stud 16. The bottom of the U-shaped profile of the piece 17 has a toothing 28. The part 17 is also traversed by a longitudinal metal rod 29 provided with a toothing, for example a simple threaded rod, fixed by one of its ends in the lower end 7a of the housing 7. The other end of the threaded rod 29 engages freely in a passage 30 formed in the pusher 12. The rod 29 is fixed at a level such that the toothing 28 of the part 17 is engaged in the toothing of the rod 29 under the effect of the spring 27. The stud 16 is consequently immobilized on the rod 29. To move the stud 16, it suffices to press on the pusher 26, which releases the part 17 from the threaded rod 29 and allows its rapid displacement all along this rod 29. As soon as you release the pressure on the po ussoir 26, the pad 16 stops in its new position. The cover 9 has a longitudinal rectangular slot 31 of width equal to that of the pusher 26 to allow movement of the stud 16. Another embodiment of the elastic member is shown in Figures 6 and 7. In this embodiment, the elastic member is constituted by a rubber plate 32 of rectangular parallelepiped shape but the lower face of which has a depression 32a creating an axial asymmetry so that the buckling of the bag 32 is always upwards. This plate is mounted in a housing 33 formed in a base 34 attached to the shell 1 or come in one piece with this shell, in the same way as the housing 7. The thrust of the articulated part 2 of the shell is transmitted by a plunger 35 of generally rectangular shape and provided with a rectangular notch 36 in which the elastic plate 32 engages. The housing 33 is closed by a cover 37 fixed to the base 34 by any known means such as gluing, welding, notching or by means of screws. This cover 7 has a longitudinal axial slot 38 crossed by a slider 39, the inner part of which has a T-shaped transverse widening extending under the cover 37. Under the head of the slider 39 is a plate 41 made of compressed elastic material, which tends to hold the enlarged part 40 of the cursor against the inner wall of the cover 37. This part of the wall is provided with a toothing 42 cooperating with teeth 43 provided on the enlarged part 40 of the cursor. To release the cursor, simply press the cursor which can then be moved axially along the slot 38. The elastic plate 32 has been shown in the compressed position. We see that the left part of the plate 32 cannot flame because it is retained by the cursor. By moving the slider we can thus vary the length likely to buckle. According to an alternative embodiment, the enlarged part 40 slightly compresses, at rest, the plate 32 which keeps the teeth 43 in engagement with the teeth 42. The plate 32 thus replaces the auxiliary plate 41.

Une variante d'exécution de la première forme d'exécution est représentée aux figures 8 et 9. La figure 8 représente à nouveau une chaussure complète analogue à la chaussure représentée à la figure 1 en ce qui concerne la coque et la boucle de fermeture 5. Le logement 8 prévu pour deux barres en caoutchouc identiques aux barres 10 et 11 est formé dans un socle 43 rapporté sur la coque 1. Ce logement est fermé par un couvercle 44 présentant sur sa face supérieure une rainure longitudinale 45 présentant un profil en queue d'aronde. Dans cette rainure est monté un coulisseau 46 allongé de même profil que la rainure 45 et recouvrant en toute position une fente longitudinale 47 pratiquée axialement dans le couvercle 44 et visible à la figure 9. Le coulisseau 46 porte en son centre un poussoir 48 traversant la fente 47 et présentant à son extrémité inférieure une tête 48a en forme de bulbe retenue dans un logement 49 en forme de pince d'un plot 50 en matière plastique. Toutes les pièces décrites jusqu'ici sont réalisées de préférence en matière synthétique. Sous la tête du poussoir 48 est logée une garniture d'étanchéité 51 en matière synthétique facilement compressible. A sa partie inférieure le plot 50 présente une languette recourbée flexible 52, venue d'une pièce avec le plot 50, et s'appuyant, sous flexion, contre la coque 1. Cette languette élastique 52 joue le rôle de ressort de compression et a tendance à appliquer le plot 5 contre le couvercle 44. De chaque côté de la fente 47, la face intérieure du couvercle est munie d'une denture 53 dans laquelle s'engagent deux dents transversales 54 et 55 du plot 50. Pour déplacer le plot 50 il suffit d'appuyer sur le poussoir 48 et de déplacer le coulisseau ou curseur 46. L'une des positions extrêmes du plot 5 est représentée en trait plein tandis que l'autre position extrême est représenté en trait mixte. Cette exécution n'exige aucune pièce métallique et ne laisse subsister aucun orifice par lequel la neige pourrait pénétrer dans le logement contenant les éléments en caoutchouc.An alternative embodiment of the first embodiment is shown in Figures 8 and 9. Figure 8 shows again a complete shoe similar to the shoe shown in Figure 1 with regard to the shell and the closure loop 5 The housing 8 provided for two rubber bars identical to the bars 10 and 11 is formed in a base 43 attached to the shell 1. This housing is closed by a cover 44 having on its upper face a longitudinal groove 45 having a tail profile dovetail. In this groove is mounted a slide 46 elongated with the same profile as the groove 45 and covering in any position a longitudinal slot 47 made axially in the cover 44 and visible in FIG. 9. The slide 46 carries in its center a pusher 48 passing through the slot 47 and having at its lower end a bulb-shaped head 48a retained in a housing 49 in the form of a clamp of a stud 50 made of plastic. All the parts described so far are preferably made of synthetic material. Under the head of the pusher 48 is housed a seal 51 made of easily compressible synthetic material. At its lower part, the stud 50 has a flexible curved tongue 52, coming in one piece with the stud 50, and pressing, under bending, against the shell 1. This elastic tongue 52 acts as a compression spring and has tendency to apply the stud 5 against the cover 44. On each side of the slot 47, the inner face of the cover is provided with a toothing 53 in which two transverse teeth 54 and 55 of the stud 50 engage. To move the stud 50 it suffices to press on the pusher 48 and to move the slider or cursor 46. One of the extreme positions of the stud 5 is shown in solid lines while the other extreme position is shown in phantom. This execution requires no metal parts and does not leave any hole through which snow could enter the housing containing the rubber elements.

L'invention est susceptible de nombreuses variantes d'exécution. En particulier les pièces allongées élastiques travaillant en flambage pourraient être réalisées en matière non organique, par exemple en acier ou en fibre minérale.The invention is susceptible of numerous variants. In particular, the elongated elastic pieces working in buckling could be made of inorganic material, for example steel or mineral fiber.

D'autre part, l'asymétrie axiale des pièces élastiques peut être obtenue par de nombreuses formes. Une manière simple d'obtenir l'asymétrie est de donner une forme en biseau à l'une au moins des extrémités des barres ou plaquettes ou de donner une légère courbure initiale à la pièce élastique.On the other hand, the axial asymmetry of the elastic parts can be obtained by many forms. A simple way to obtain asymmetry is to give a bevel shape to at least one of the ends of the bars or plates or to give a slight initial curvature to the elastic piece.
