Description

La présente invention a pour objet une chaussure de ski en matière plastique constituée essentiellement d'une coque entourant le pied et le talon, d'une tige en forme de collier articulé sur la coque et d'une armature rigide reliant la partie postérieure du collier à la coque.The present invention relates to a ski boot made of plastic material essentially consisting of a shell surrounding the foot and the heel, a rod-shaped rod articulated on the shell and a rigid frame connecting the rear part of the collar. soft-boiled.

Du brevet FR 2 330 345 (US 4 085 528), on connaît une chaussure en matière thermo-plastique comportant une coque et un collier relié à la coque par une armature en U constituée d'une tige d'acier de section circulaire. L'armature présente deux branches s'étendant de part et d'autre de la partie postérieure du collier, ces branches étant ensuite coudées obliquement vers l'avant pour venir s'encatrer dans deux pièces solidaires de la coque. Cette armature a pour but de mieux maîtriser la flexibilité de la chaussure, indépendamment de la flexibilité propre de la matière plastique. Elle permet également de régler la flexibilité de la chaussure. Cette structure a également pour effet d'augmenter la rigidité en torsion et par conséquent d'améliorer la transmission d'un effort de torsion sur les skis lors de la prise de carre en virage.From patent FR 2 330 345 (US 4 085 528), a shoe made of thermo-plastic material is known comprising a shell and a collar connected to the shell by a U-shaped frame consisting of a steel rod of circular section. The frame has two branches extending on either side of the rear part of the collar, these branches then being bent obliquely forward to come and fit into two parts integral with the shell. The purpose of this frame is to better control the flexibility of the shoe, independently of the inherent flexibility of the plastic. It also allows you to adjust the flexibility of the shoe. This structure also has the effect of increasing the torsional rigidity and consequently of improving the transmission of a torsional force on the skis when taking an edge when cornering.

La transmission des efforts au ski se fait toutefois encore par l'intermédiaire de la chaussure, de telle sorte que la rapidité et la précision de la transmission des efforts au ski est encore dépendante de la rigidité de la chaussure. Plus la rigidité est grande, plus la réponse du ski est rapide. La rigidité de la chaussure ne peut toutefois être augmentée sans augmentation de l'épaisseur, de la matière plastique, donc du coût et du poids et au détriment du confort. Une diminution de la flexibilité de la chaussure vers l'avant, s'opposant à la flexion de la jambe, est en outre défavorable.The transmission of forces to the ski, however, still takes place via the boot, so that the speed and precision of the transmission of the forces to the ski is still dependent on the stiffness of the boot. The greater the rigidity, the faster the response of the ski. The rigidity of the shoe cannot however be increased without increasing the thickness, the plastic material, therefore the cost and the weight and at the expense of comfort. A decrease flexibility of the shoe forward, opposing the flexion of the leg, is also unfavorable.

La présente invention a pour but d'améliorer la transmission des efforts au ski afin d'obtenir une réponse du ski beaucoup plus rapide, notamment lors du changement de carre. Ce but doit être atteint indépendamment des caractéristiques de la matière plastique constituant la chaussure, c'est-à-dire sans qu'il soit nécessaire d'augmenter la rigidité et/ou l'épaisseur de celle-ci.The object of the present invention is to improve the transmission of forces to the ski in order to obtain a much faster response from the ski, in particular when the edge is changed. This object must be achieved independently of the characteristics of the plastic material constituting the shoe, that is to say without it being necessary to increase the rigidity and / or the thickness thereof.

La chaussure de ski selon l'invention est caractérisée en ce que l'armature comprend une partie en forme d'arceau intégrée au talon de la chaussure et fixée à la coque dans un plan sensiblement horizontal.The ski boot according to the invention is characterized in that the frame comprises a hoop-shaped part integrated into the heel of the boot and fixed to the shell in a substantially horizontal plane.

La partie supérieure de l'armature pourrait être réalisée comme représenté dans le brevet FR 2 330 345 ou, par exemple, comprendre une partie médiane fixée au dos du collier, cette partie médiane étant reliée par deux bras inférieurs aux extrémités de l'arceau et par deux bras supérieurs aux flancs du collier.The upper part of the frame could be made as shown in patent FR 2 330 345 or, for example, include a middle part fixed to the back of the collar, this middle part being connected by two lower arms at the ends of the hoop and by two arms upper to the sides of the collar.

Ainsi, tout mouvement de basculement latéral de la jambe, de part et d'autre du plan de joint longitudinal de la chaussure, est transmis directement à la fixation, c'est-à-dire au ski par l'armature rigide. Le ski répond immédiatement à tout ordre de changement de carre et la prise de carre devient plus précise et plus sûre.Thus, any lateral tilting movement of the leg, on either side of the longitudinal joint plane of the boot, is transmitted directly to the binding, that is to say to the ski by the rigid frame. The ski responds immediately to any edge change order and the edge grip becomes more precise and safer.

L'armature sera, en principe, exécutée en métal, mais tout matériau synthétique présentant une rigidité suffisante pourrait être également utilisé.The framework will, in principle, be made of metal, but any synthetic material with sufficient rigidity could also be used.

L'arceau intégré au talon de la chaussure constitue de préférence la partie supérieure du talon et supportera donc la pression de la talonnière de la fixation du ski. La hauteur de la partie en plastique du talon est réduite de manière que la hauteur totale du talon corresponde aux normes.The arch integrated into the heel of the boot preferably constitutes the upper part of the heel and will therefore support the pressure from the heel of the binding of the ski. The height of the plastic part of the heel is reduced so that the total height of the heel corresponds to the standards.

L'armature peut être réalisée en une seule pièce ou en plusieurs pièces.The frame can be made in one piece or in several pieces.

Si l'armature est constituée de plusieurs pièces, ces pièces peuvent être constituées de matériaux différents. Il est ainsi possible de réaliser l'arceau en matière synthétique rigide auto-lubrifiante, telle que du TEFLON (marque déposée) de manière à augmenter la sécurité de fonctionnement de la fixation de ski lors du déclenchement de celle-ci, notamment en cas de déclenchement lors d'une sollicitation en torsion.If the reinforcement consists of several parts, these parts can be made of different materials. It is thus possible to produce the arch in rigid self-lubricating synthetic material, such as TEFLON (registered trademark) so as to increase the operating safety of the ski binding when it is released, in particular in the event of tripping when subjected to torsional stress.

L'armature peut être aisément exécutée sous une forme interchangeable.The frame can be easily executed in an interchangeable form.

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

La figure 1 est une vue en perspective d'une chaussure selon une première forme d'exécution.Figure 1 is a perspective view of a shoe according to a first embodiment.

La figure 2 représente un éclaté de l'armature.Figure 2 shows an exploded view of the frame.

La figure 3 représente une variante d'exécution des bras supérieurs de l'armature.Figure 3 shows an alternative embodiment of the upper arms of the frame.

La figure 4 est un éclaté d'une seconde forme d'exécution.Figure 4 is an exploded view of a second embodiment.

La figure 5 est une vue en perspective et en coupe de la deuxième forme d'exécution.Figure 5 is a perspective view in section of the second embodiment.

La figure 6 représente une variante d'exécution de la première forme d'exécution.FIG. 6 represents an alternative embodiment of the first embodiment.

La figure 7 représente une troisième forme d'exécution.Figure 7 shows a third embodiment.

Les figures 1 et 2 représentent schématiquement une coque 1 sur laquelle est articulée la tige de la chaussure constituée d'un collier 2 dont le dos présente une face 3 plane ou légèrement cintrée autour d'un axe transversal à la chaussure. On distingue également la partie supérieure d'un chausson intérieur 4. Ce type de chaussure est bien connu en soi.Figures 1 and 2 schematically represent a shell 1 on which is articulated the upper of the shoe consisting of a collar 2 whose back has a flat face 3 or slightly curved about an axis transverse to the shoe. There is also the upper part of an inner liner 4. This type of shoe is well known in itself.

La chaussure comporte en outre une armature 5 constituée ici de trois pièces 51, 52, 53. La pièce médiane 51 est constituée d'un profil en U venant s'emboîter sur le dos du collier 2 et s'appliquer contre sa face dorsale 3. Elle est fixée au collier 2 par deux vis 6. La vis supérieure 6 traverse le dos 3 à travers un trou oblong vertical 7 pour venir se visser dans un écrou à l'intérieur du collier. La vis inférieure 6 traverse le dos 3 à travers un trou oblong 8 pour venir se visser également dans un écrou fixe solidaire de la coque. La pièce 51 présente en outre une rangée verticale de trous 9 servant d'une part, à alléger la pièce 51 et, d'autre part, à permettre une utilisation en plusieurs parties et à permettre un ajustement de la flexion.The shoe further comprises a frame 5 here made up of three pieces 51, 52, 53. The middle piece 51 consists of a U-shaped profile which fits onto the back of the collar 2 and is applied against its dorsal face 3 It is fixed to the collar 2 by two screws 6. The upper screw 6 crosses the back 3 through a vertical oblong hole 7 to be screwed into a nut inside the collar. The lower screw 6 crosses the back 3 through an oblong hole 8 to also be screwed into a fixed nut secured to the shell. The part 51 also has a vertical row of holes 9 serving on the one hand, to lighten the part 51 and, on the other hand, to allow use in several parts and to allow an adjustment of the bending.

La pièce inférieure 52 présente, à sa partie supérieure, un profil 10 venant s'emboîter dans un profil conjugué de la pièce 51. Le profil 10 présente un trou 11 pour le passage de la vis 6 qui sert simultanément à la solidarisation des pièces 51 et 52 et à la solidarisation de la pièce 52 sur la coque. La pièce 52 présente deux bras 12 et 13 s'étendant de part et d'autre de la partie arrière de la coque 1 et reliés à un arceau 14 entourant le talon de la chaussure dans un plan horizontal. L'arceau 4 vient se loger dans une gorge 15 de la coque de manière à être intégré au talon de la chaussure et former la partie supérieure de ce talon, dont la partie inférieure 16 est constituée par la matière plastique de la coque. La hauteur totale des parties 14 et 16 est égale à la hauteur normalisée du talon et leur forme assemblée est celle de la norme. A la jonction des bras 12 et 13 et de l'arceau 14, la pièce 52 présente des trous 17 et 18 pour le passage d'une vis 19 traversant la coque 1 par un passage 20. La vis 19 traverse également un support plantaire 21 à travers un trou 22. La vis 19 se visse dans le trou 17 taraudé.The lower part 52 has, at its upper part, a profile 10 which fits into a conjugate profile of the part 51. The profile 10 has a hole 11 for the passage of the screw 6 which is used simultaneously for securing the parts 51 and 52 and the attachment of the part 52 to the hull. The part 52 has two arms 12 and 13 extending on either side of the rear part of the shell 1 and connected to a hoop 14 surrounding the heel of the shoe in a horizontal plane. The arch 4 is housed in a groove 15 of the shell so as to be integrated into the heel of the shoe and form the upper part of this heel, the lower part 16 of which is formed by the plastic material of the shell. The total height of parts 14 and 16 is equal to the normalized height of the heel and their assembled shape is that of the standard. At the junction of the arms 12 and 13 and the arch 14, the part 52 has holes 17 and 18 for the passage of a screw 19 passing through the shell 1 through a passage 20. The screw 19 also passes through a plantar support 21 through a hole 22. The screw 19 screws into the tapped hole 17.

La pièce 53 est en forme d'étrier présentant une partie médiane droite 23 et deux bras 24 et 25 s'étendant de chaque côté du collier 2. L'étrier 53 est fixé par sa partie médiane 23 à la pièce médiane 51 dans l'un des trous 9 au moyen d'une vis 26 coopérant avec un écrou 36. Chacun des bras 24 et 25 présente, à son extrémité, un tenon 27 dirigé vers l'intérieur et portant un flasque 28 à son extrémité. Chacun de ces tenons vient s'engager dans une encoche arrondie 29 prévue sur chacun des côtés du bord supérieur du collier 2. Le flasque 28 correspondant vient s'engager à l'intérieur du collier, de telle sorte que les bras sont accrochés au collier aussi bien longitudinalement que transversalement. A l'arrière des encoches 29, le bord du collier présente une rampe ascendante 30.The part 53 is in the form of a stirrup having a straight middle part 23 and two arms 24 and 25 extending on each side of the collar 2. The stirrup 53 is fixed by its middle part 23 to the middle part 51 in the one of the holes 9 by means of a screw 26 cooperating with a nut 36. Each of the arms 24 and 25 has, at its end, a lug 27 directed inwards and carrying a flange 28 at its end. Each of these tenons engages in a rounded notch 29 provided on each of the sides of the upper edge of the collar 2. The corresponding flange 28 engages inside the collar, so that the arms are hooked to the collar both longitudinally and transversely. AT behind the notches 29, the edge of the collar has an ascending ramp 30.

Comme ceci ressort de la figure 1, tout basculement de la chaussure de part et d'autre de son plan médian longitudinal, selon la double flèche F1, est transmis directement par les bras 24 et 25 de l'armature à l'arceau 14, c'est-à-dire à la fixation de ski.As can be seen from FIG. 1, any tilting of the shoe on either side of its longitudinal median plane, along the double arrow F1, is transmitted directly by the arms 24 and 25 of the frame to the arch 14, that is to say the ski binding.

Les trous oblongs 7 et 8, ainsi que le mode d'accrochage des bras 24 et 25 au collier 2 permettent de conserver la flexibilité de la chaussure vers l'avant. Lorsqu'un effort de flexion est exercé sur le collier 2, les tenons 27 peuvent, en raison de la flexibilité de la matière du collier, se déplacer légèrement le long des rampes 30 en autorisant ainsi la flexion vers l'avant.The oblong holes 7 and 8, as well as the method of attachment of the arms 24 and 25 to the collar 2, allow the flexibility of the shoe to be kept forward. When a bending force is exerted on the collar 2, the pins 27 may, due to the flexibility of the material of the collar, move slightly along the ramps 30, thereby allowing forward bending.

La figure 3 représente une variante d'exécution de la pièce 53. Elle en diffère en ce que les bras 24' et 25' sont reliés à la partie médiane 23' par des charnières 31 et 32 permettant aux bras de se déplacer selon les doubles flèches, la largeur de l'étrier peut ainsi s'adapter à la jambe, c'est-à-dire aux différents types de mollets. La transmission des mouvements de basculement selon F1 n'est pas altérée par ces articulations car elle s'effectue par la pièce 51.Figure 3 shows an alternative embodiment of the part 53. It differs in that the arms 24 'and 25' are connected to the middle part 23 'by hinges 31 and 32 allowing the arms to move in double arrows, the width of the stirrup can thus adapt to the leg, that is to say to the different types of calves. The transmission of tilting movements along F1 is not altered by these articulations because it is effected by the part 51.

L'armature peut être réalisée par exemple en alliage métallique léger, en matière synthétique, en matériau composite ou en tout autre matériau adéquat.The frame can be made for example of light metal alloy, synthetic material, composite material or any other suitable material.

L'armature 5 peut être réalisée en une seule pièce. Une telle exécution 5' est représentée à la figure 4. Pour le reste, l'armature 5' est analogue à l'armature 5 et, de manière à éviter des répétition inutiles, les parties correspondantes ont été désignées par les mêmes références qu'à la figure 2 avec l'adjonction d'un signe '. Dans ce cas, la position des bras 24' et 25' relativement à la partie médiane de l'armature n'est donc pas réglable et ces bras donc sont simplement situés à l'extrémité supérieure de la partie médiane.The frame 5 can be made in one piece. Such an embodiment 5 ′ is shown in FIG. 4. For the rest, the frame 5 ′ is similar to the frame 5 and, so as to avoid unnecessary repetition, the corresponding parts have been designated by the same references as in FIG. 2 with the addition of a sign '. In this case, the position of the arms 24 'and 25' relative to the middle part of the frame is therefore not adjustable and these arms therefore are simply located at the upper end of the middle part.

Comme déjà mentionné dans l'introduction, les arceaux 14 et 14' pourraient être réalisés en matière plastique auto-lubrifiante.As already mentioned in the introduction, the arches 14 and 14 'could be made of self-lubricating plastic.

Afin d'améliorer la flexibilité de la chaussure vers l'avant on peut relier les pièces 51 et 52 de la figure 1 par une articulation 33 comme représenté à la figure 6. L'axe de cette articulation est parallèle à l'articulation du collier sur la coque.In order to improve the flexibility of the shoe towards the front, the parts 51 and 52 of FIG. 1 can be connected by an articulation 33 as shown in FIG. 6. The axis of this articulation is parallel to the articulation of the collar on the hull.

Dans le cas d'une chaussure de type MID ENTRY (par exemple CH-A-678 385), c'est-à-dire une chaussure dont le collier doit pouvoir basculer vers l'arrière pour le chaussage et la marche, l'armature doit pouvoir autoriser ce mouvement. Un exemple d'exécution est représenté à la figure 7. La chaussure est constituée d'une coque 1' sur laquelle est articulé un collier 2'. L'armature comprend à nouveau les parties 51 et 25, mais la partie 51 est fixée à un étrier 34 articulé sur les rivets 35 d'articulation du collier sur la coque et, par ces mêmes rivets, aux extrémités de deux bras 14a de l'arceau 14. En position de ski le collier 2' est verrouillé sur la coque 1' et l'armature est parfaitement rigide en basculement latéral. Les parties 51 et 34 pourraient être d'une seule pièce.In the case of a shoe of the MID ENTRY type (for example CH-A-678 385), that is to say a shoe whose collar must be able to tilt backwards for putting on and walking, the armature must be able to authorize this movement.
