Description

L'invention concerne une chaussure de ski à coque rigide comprenant un bas de coque et un collier reliés de manière articulée par l'intermédiaire d'une bague de liaison.The invention relates to a rigid-shell ski boot comprising a hull bottom and a collar hingedly connected by means of a connecting ring.

Une chaussure de ski exige une rigidité et une résistance importantes car elle subit de nombreux efforts lors de son utilisation. Une forte rigidité est aussi nécessaire pour atteindre une bonne performance de la chaussure qui, en tant qu'intermédiaire entre le skieur et le ski, transmet les efforts du skieur au ski afin de guider ce dernier. Toutefois, la chaussure doit aussi permettre au skieur de l'ouvrir pour la chausser et l'enlever et lui permettre de fléchir ses genoux vers l'avant pour skier. Cette flexion est atteinte par l'articulation du collier sur le bas de coque, ce dernier étant solidarisé au ski. Cet agencement nécessite un axe d'articulation entre le collier et le bas de coque, axe qui remplit un rôle important puisqu'il participe à la transmission des efforts du skieur vers le ski. En effet, tous les efforts passent du collier au bas de coque, puis au ski, principalement par l'axe d'articulation. D'autre part, cet agencement permet aussi de déterminer la mobilité relative entre le collier et le bas de coque, ou d'autres paramètres comme par exemple l'angle d'inclinaison, ce qui participe aussi au confort et à la performance globale de la chaussure.A ski boot requires rigidity and significant resistance because it undergoes many efforts during its use. Strong rigidity is also necessary to achieve a good performance of the shoe which, as an intermediary between the skier and the ski, transmits the efforts of the skier to the ski to guide the latter. However, the boot must also allow the skier to open it for putting on and off and allowing him to flex his knees forward to ski. This flexion is reached by the articulation of the collar on the shell bottom, the latter being secured to the ski. This arrangement requires a hinge axis between the collar and the bottom of the hull, which axis plays an important role since it participates in the transmission of the efforts of the skier to the ski. Indeed, all efforts go from the collar to the bottom of the hull, then the ski, mainly by the hinge pin. On the other hand, this arrangement also makes it possible to determine the relative mobility between the collar and the shell bottom, or other parameters such as, for example, the angle of inclination, which also contributes to the comfort and overall performance of the hull. the shoe.

EP2 620 068 divulgue une chaussure de ski avec une articulation renforcée. EP2 620 068 discloses a ski boot with a reinforced hinge.

Ainsi, un objet général de la présente invention consiste à proposer un agencement permettant la liaison optimisée entre un collier et un bas de coque, qui permet d'optimiser la performance de la chaussure.Thus, a general object of the present invention is to provide an arrangement for the optimized connection between a collar and a shell bottom, which optimizes the performance of the shoe.

Notamment, un premier objet de la présente invention consiste à proposer une chaussure de ski permettant la transmission performante des efforts du skieur vers le ski.In particular, a first object of the present invention is to provide a ski boot for the efficient transmission of the efforts of the skier to the ski.

Un second objet optionnel de la présente invention consiste à proposer une chaussure de ski permettant le réglage de l'inclinaison du collier par rapport au bas de coque.A second optional object of the present invention is to provide a ski boot for adjusting the inclination of the collar relative to the bottom of the shell.

Selon le concept de l'invention, la chaussure atteint ces objets par l'intermédiaire d'une bague de liaison spécifique reliant de manière articulée le collier et le bas de coque, qui garantit une bonne transmission des efforts et un bon comportement de la chaussure de ski. Pour cela, la bague de liaison comprend une surface de blocage agencée dans une ouverture du bas de coque, de sorte à empêcher la rotation de la bague de liaison relativement au bas de coque, et une surface de rotation agencée dans une ouverture du collier de sorte à guider la rotation du collier relativement au bas de coque autour de cette seconde surface. Cette surface de rotation présente avantageusement une dimension importante.According to the concept of the invention, the shoe reaches these objects by means of a specific connecting ring hingedly connecting the collar and the shell bottom, which guarantees a good transmission of efforts and a good behavior of the shoe ski. For this, the connecting ring comprises a blocking surface arranged in an opening of the shell bottom, so as to prevent the rotation of the connecting ring relative to the shell bottom, and a rotational surface arranged in an opening of the collar of so as to guide the rotation of the collar relative to the shell bottom around this second surface. This rotation surface advantageously has a large dimension.

La figure 1 illustre une chaussure de ski alpin 1 selon un mode de réalisation de l'invention, qui comprend une coque externe rigide, par exemple formée en matériau plastique injecté, par exemple en polyuréthane, ou en polyamide ou encore en polyoléfine. Cette coque rigide comprend notamment un collier 20 articulé sur un bas de coque 30 autour d'un axe de liaison par l'intermédiaire d'une bague de liaison 10. Le bas de coque 30 s'étend, dans la direction verticale, depuis la semelle de marche 6 jusqu'au-delà du niveau de l'axe d'articulation et de liaison avec le collier 20. Cet axe d'articulation est positionné latéralement, à une hauteur sensiblement au niveau ou peu au-dessus de la malléole du pied d'un skieur, voire au niveau de sa cheville. Un chausson de confort 5 est inséré dans la coque rigide. La semelle 6 est prolongée vers ses deux extrémités avant et arrière par des trottoirs 7 de format adapté pour la coopération avec les mâchoires d'un dispositif de fixation de chaussure de ski, qui permet le maintien du bas de coque 30 sur le ski, alors que le collier 20 reste articulé autour de son axe d'articulation sensiblement transversal par rapport au bas de coque.The figure 1 illustrates an alpine ski boot 1 according to one embodiment of the invention, which comprises a rigid outer shell, for example formed of injected plastic material, for example polyurethane, or polyamide or polyolefin. This rigid shell comprises in particular a collar 20 hinged to a bottom of shell 30 around a connecting axis via a connecting ring 10. The bottom of shell 30 extends, in the vertical direction, from the running sole 6 to beyond the level of the axis of articulation and connection with the collar 20. This axis of articulation is positioned laterally, at a height substantially at or slightly above the malleolus of the foot of a skier, even at the level of his ankle. A comfort slipper 5 is inserted into the rigid shell. The sole 6 is extended towards its two front and rear ends by sidewalks 7 of a format adapted for cooperation with the jaws of a ski boot binding device, which allows the bottom shell 30 to be held on the ski, while that the collar 20 remains articulated about its axis of articulation substantially transverse to the bottom of the shell.

L'invention porte plus spécifiquement sur la liaison articulée entre le collier 20 et le bas de coque 30, par l'intermédiaire de la bague de liaison 10. Les figures 2 à 5 illustrent plus précisément l'agencement de liaison entre le collier 20 et le bas de coque 30 selon le mode de réalisation de l'invention.The invention relates more specifically to the articulated connection between the collar 20 and the shell bottom 30, via the connecting ring 10. Figures 2 to 5 illustrate more precisely the connection arrangement between the collar 20 and the shell bottom 30 according to the embodiment of the invention.

Le bas de coque 30 comprend une ouverture traversante 34, de dimension prévue pour le passage d'un écrou 19 depuis sa surface intérieure. Il comprend de plus une ouverture 31, traversante ou en variante non totalement traversante agencée depuis sa surface extérieure. Selon ce mode de réalisation, cette ouverture 31 est non traversante et présente une section carrée. Le collier 20 présente une ouverture traversante 24, formée à partir de sa paroi intérieure par une première ouverture 22 cylindrique. L'axe de rotation 15 du collier 20 par rapport au bas de coque 30 correspond à l'axe qui passe par le centre de l'ouverture 24. A partir de sa surface extérieure, le collier 20 comprend une seconde ouverture 23, cylindrique, non traversante, c'est-à-dire qu'elle ne s'étend pas sur toute l'épaisseur du collier 20. Les deux ouvertures cylindriques 22, 23 du collier 20 forment deux portions de cylindre coaxiales et de diamètre différent.The shell bottom 30 comprises a through opening 34, of dimension provided for the passage of a nut 19 from its inner surface. It further comprises an opening 31, through or alternatively not completely through arranged from its outer surface. According to this embodiment, this opening 31 is non-through and has a square section. The collar 20 has a through opening 24 formed from its inner wall by a first cylindrical opening 22. The axis of rotation 15 of the collar 20 relative to the bottom of the shell 30 corresponds to the axis which passes through the center of the opening 24. From its outer surface, the collar 20 comprises a second, cylindrical opening 23, non-through, that is to say, it does not extend over the entire thickness of the collar 20. The two cylindrical openings 22, 23 of the collar 20 form two coaxial cylinder portions and of different diameter.

Ces ouvertures agencées dans les parois du collier 20 et du bas de coque 30 sont prévues pour venir en correspondance lors du montage de la chaussure de ski. Une bague de liaison 10 est alors agencée dans ces ouvertures, pour permettre la liaison articulée du collier 20 et du bas de coque 30.These openings arranged in the walls of the collar 20 and the bottom of shell 30 are provided to come into correspondence during assembly of the ski boot. A connecting ring 10 is then arranged in these openings, to allow the articulated connection of the collar 20 and the shell bottom 30.

La bague de liaison 10 comprend trois parties complémentaires sur son épaisseur. Cette épaisseur se mesure dans la direction sensiblement transversale de la chaussure. Cette bague de liaison 10 présente une ouverture traversante 14 dont le centre est aligné avec le centre de l'ouverture 34 pratiquée dans le bas de coque 30. Comme illustré sur les figures 1 à 5, selon ce mode de réalisation, le centre de l'ouverture 14 correspond à l'axe de rotation 15 de la surface de rotation 12, autour de laquelle tourne le collier 20 par sa surface 22. Plus généralement, dans ce mode de réalisation, les centres des ouvertures 14, 24 et 34 sont alignés avec l'axe de rotation 15. Une première partie de la bague de liaison 10 forme une surface de blocage 11, destinée à un logement dans l'ouverture 31 pratiquée dans la surface extérieure du bas de coque 30. Dans ce mode de réalisation, cette surface de blocage 11 présente donc une section sensiblement proche d'un carré, de dimensions correspondant à celles du logement correspondant du bas de coque 30. Selon le mode de réalisation de l'invention, la surface de blocage 11 de la bague 10 a une section carrée de côté compris entre 0,7 et 1,5 centimètre, de préférence 1 centimètre, et une épaisseur comprise entre 0,1 et 0,7 centimètre, de préférence 0,3 centimètre. Elle permet le blocage de la rotation de la bague de liaison relativement au bas de coque 30. Ensuite, cette bague de liaison 10 comprend une seconde partie intermédiaire cylindrique, formant une surface de rotation 12 périphérique, logée au sein de l'ouverture 22 cylindrique réalisée à partir de la surface intérieure du collier 20, dont la paroi est destinée à coopérer à moindre jeu avec cette surface de rotation 12 périphérique de la bague de liaison 10. Cet agencement permet de réaliser une mobilité en rotation du collier 20 relativement à la bague de liaison 10, plus particulièrement autour de la surface de rotation 12 périphérique, et par conséquent une mobilité en rotation du collier 20 relativement au bas de coque 30 autour de l'axe de rotation 15. Enfin, la troisième partie 13 de la bague de liaison 10 présente une plus grande dimension, qui forme une tête, qui vient se loger dans l'ouverture non traversante 23 du côté de la surface extérieure du collier 20, qui forme une butée pour la bague de liaison et évite tout déplacement relatif de la bague de liaison et du collier en direction transversale, et en particulier évite la sortie du collier vers l'extérieur de la chaussure. Cette troisième partie 13 présente une troncature 16 permettant de visualiser l'orientation de la bague de liaison 10. Par ailleurs, la troncature 16 permet également le démontage de la bague de liaison 10 à l'aide d'un outil adapté, par exemple un tournevis à tête plate. Ensuite, une vis 18 est insérée à l'intérieur de la bague de liaison 10, au travers de l'ouverture traversante 14 de la bague de liaison, par la surface extérieure de la chaussure de ski, et coopère avec un écrou 19 inséré à l'opposé par la surface intérieure du bas de coque de la chaussure. Cet ensemble permet de solidariser la bague de liaison 10 à la chaussure de ski.The connecting ring 10 comprises three complementary parts over its thickness. This thickness is measured in the substantially transverse direction of the shoe. This connecting ring 10 has a through opening 14 whose center is aligned with the center of the opening 34 formed in the shell bottom 30. As shown in FIGS. Figures 1 to 5 according to this embodiment, the center of the opening 14 corresponds to the axis of rotation 15 of the rotation surface 12, around which the collar 20 rotates by its surface 22. More generally, in this embodiment, the centers of the openings 14, 24 and 34 are aligned with the axis of rotation 15. A first portion of the connecting ring 10 forms a locking surface 11, intended for a housing in the opening 31 formed in the outer surface of the In this embodiment, this locking surface 11 thus has a section substantially close to a square, of dimensions corresponding to those of the corresponding housing of the bottom shell 30. According to the embodiment of the invention the blocking surface 11 of the ring 10 has a square cross-section of between 0.7 and 1.5 centimeters, preferably 1 centimeter, and a thickness of between 0.1 and 0.7 centimeters, preferably 0, 3 centimeters. It allows the locking of the rotation of the connecting ring relative to the bottom shell 30. Then, this connecting ring 10 comprises a second cylindrical intermediate portion, forming a peripheral rotating surface 12, housed within the cylindrical opening 22 made from the inner surface of the collar 20, the wall of which is intended to cooperate with less clearance with this peripheral rotational surface 12 of the connecting ring 10. This arrangement makes it possible to achieve a rotational mobility of the collar 20 relative to the connecting ring 10, more particularly around the peripheral rotation surface 12, and consequently a rotational mobility of the collar 20 relative to the shell bottom 30 around the axis of rotation 15. Finally, the third portion 13 of the ring link 10 presents a larger dimension, which forms a head, which is housed in the non-through opening 23 on the side of the outer surface of the collar 20, which forms a stop for the connecting ring and prevents any relative displacement of the connecting ring and the collar in transverse direction, and in particular avoids the exit of the collar to the outside of the shoe. This third part 13 has a truncation 16 making it possible to visualize the orientation of the connecting ring 10. Furthermore, the truncation 16 also allows the disassembly of the connecting ring 10 by means of a suitable tool, for example a flat head screwdriver. Then, a screw 18 is inserted inside the connecting ring 10, through the through opening 14 of the connecting ring, by the outer surface of the ski boot, and cooperates with a nut 19 inserted into the opposite by the inner surface of the shell bottom of the shoe. This assembly makes it possible to secure the connecting ring 10 to the ski boot.

Comme cela apparaît plus particulièrement sur la figure 3, l'épaisseur totale de la bague de liaison 10 correspond sensiblement à l'épaisseur des parois du collier 20 et du bas de coque 30, de sorte qu'en position finale, la bague de liaison 10 est sensiblement totalement insérée dans les épaisseurs de ces éléments. Dans cette zone, l'épaisseur du bas de coque est en général comprise entre 0,3 et 0,6 centimètre, de préférence sensiblement égale à 0,4 centimètre, et l'épaisseur du collier est en général comprise entre 0,4 et 0,7 centimètre, de préférence sensiblement égale à 0,5 centimètre. On ne sortira cependant pas du cadre de l'invention si la bague de liaison 10 présente une excroissance positionnée au-delà de la surface extérieure du collier 20.As it appears more particularly on the figure 3 , the total thickness of the connecting ring 10 substantially corresponds to the thickness of the walls of the collar 20 and the bottom shell 30, so that in the final position, the connecting ring 10 is substantially completely inserted into the thicknesses of these elements. In this zone, the thickness of the shell bottom is in general between 0.3 and 0.6 cm, preferably substantially equal to 0.4 cm, and the thickness of the collar is in general between 0.4 and 0.7 centimeters, preferably substantially 0.5 centimeters. However, it will not be departing from the scope of the invention if the connecting ring 10 has an outgrowth positioned beyond the outer surface of the collar 20.

Plus précisément, l'épaisseur de la première partie formant une surface de blocage 11 de la bague de liaison correspond à l'épaisseur de l'ouverture 31 de section carrée du bas de coque 30. L'extrémité de la bague de liaison 10 vient ainsi en butée au sein de l'épaisseur du bas de coque 30. Une liaison sans liberté est donc ainsi obtenue entre la bague de liaison 10 et le bas de coque 30 et assure le blocage de la rotation de la bague par rapport au bas de coque.More specifically, the thickness of the first portion forming a locking surface 11 of the connecting ring corresponds to the thickness of the opening 31 of square section of the shell bottom 30. The end of the ring link 10 thus comes into abutment within the thickness of the shell bottom 30. A link without freedom is thus obtained between the connecting ring 10 and the shell bottom 30 and ensures the locking of the rotation of the ring relative at the bottom of the hull.

Ensuite, l'épaisseur totale des seconde et troisième parties 12, 13 de la bague de liaison 10 correspond sensiblement à l'épaisseur de la paroi du collier. L'épaisseur de la seconde partie est la plus importante, car elle forme une section cylindrique dont la paroi périphérique forme une surface de rotation 12 pour le collier 20. La troisième partie 13 vient en butée extérieure, empêchant tout mouvement transversal de la bague de liaison 10 relativement au collier 20, et évitant le déplacement du collier transversalement vers l'extérieur. En remarque, la surface frontale 17 de la seconde partie vient en contact contre la surface extérieure du bas de coque, laquelle est aménagée pour former une surface plane 37 de réception afin d'assurer un contact plan et un appui optimal.Then, the total thickness of the second and third parts 12, 13 of the connecting ring 10 substantially corresponds to the thickness of the wall of the collar. The thickness of the second part is the most important because it forms a cylindrical section whose peripheral wall forms a rotational surface 12 for the collar 20. The third portion 13 comes into outer abutment, preventing any transverse movement of the ring. connection 10 relative to the collar 20, and avoiding the displacement of the collar transversely outwards. Note, the front surface 17 of the second part comes into contact against the outer surface of the shell bottom, which is arranged to form a flat receiving surface 37 to ensure a plane contact and optimal support.

La bague de liaison 10 se présente sous une forme monobloc, comprenant une surface de blocage 11 et une surface de rotation 12. Selon une variante simplifiée, elle pourrait ne pas présenter de troisième partie 13 formant une tête, ou cette partie pourrait être formée par un composant distinct, comme par exemple une rondelle ou par exemple par une partie appartenant à la vis 18. Selon une autre variante, la bague de liaison 10 peut se présenter en plusieurs éléments distincts, associés les uns avec les autres. Naturellement, la bague de liaison 10 peut présenter d'autres formes et caractéristiques. Notamment, la surface de blocage 11 pourrait présenter une autre section. Avantageusement, cette section se présente sous la forme d'un polygone comprenant entre trois et six côtés, notamment quadrilatère par exemple carrée comme représenté, ou hexagonale. La surface de rotation est choisie de grande dimension, et présente de préférence une surface supérieure à la surface de blocage et/ou présente une section de dimension supérieure à la dimension de la section de la surface de blocage. Les côtés de ce polygone peuvent être rectilignes ou encore incurvés, courbés.The connecting ring 10 is in a one-piece form, comprising a locking surface 11 and a rotating surface 12. According to a simplified variant, it could not have a third part 13 forming a head, or this part could be formed by a separate component, such as a washer or for example by a portion belonging to the screw 18. According to another variant, the connecting ring 10 may be in several distinct elements associated with each other. Naturally, the connecting ring 10 may have other shapes and features. In particular, the blocking surface 11 could have another section. Advantageously, this section is in the form of a polygon comprising between three and six sides, in particular quadrilateral for example square as shown, or hexagonal. The rotating surface is chosen large, and preferably has a surface greater than the blocking surface and / or has a section larger than the size of the section of the blocking surface. The sides of this polygon may be rectilinear or curved, curved.

La résistance de la tenue de la bague dans la coque est obtenue par une épaisseur suffisante de la surface de blocage, notamment de la forme carrée, ainsi qu'une longueur suffisante des côtés du polygone, notamment du carré.The strength of the behavior of the ring in the shell is obtained by a sufficient thickness of the blocking surface, in particular of the square shape, and a sufficient length of the sides of the polygon, including the square.

La bague de liaison 10 peut être en matériau métallique de type aluminium, mais également en plastique, en particulier en plastique chargé de fibres.The connecting ring 10 may be made of metal material of aluminum type, but also of plastic, in particular fiber-filled plastic.

Cette construction présente les avantages suivants :

  • La surface de rotation 12 autour de laquelle le collier est en mouvement de rotation est agrandie par rapport aux solutions les plus courantes qui reposent sur une seule vis semblable par exemple à la vis 18 du mode de réalisation, qui remplit la fonction d'axe de rotation du collier par rapport au bas de coque. Avec la solution selon l'invention, la section circulaire de la surface de rotation peut présenter un diamètre supérieur ou égal à 1,5 centimètre, de préférence supérieur ou égal à 1,9 centimètre, et une épaisseur comprise entre 0,2 et 1 centimètre, de préférence égale à 0,4 centimètre. Cette forte augmentation de la surface de rotation permet d'atteindre une meilleure transmission des efforts du skieur vers le ski, et un mouvement plus stable du collier, du fait notamment d'une réduction des jeux ;
  • Le bas de coque 30 et le collier 20 présentent des formes relativement simples. Leurs ouvertures 24, 31 pour recevoir la bague de liaison 10 sont obtenues par usinage, après leurs formations par un procédé conventionnel d'injection ou directement par moulage en utilisant un moule adapté. La figure 6 illustre ainsi le bas de coque 30 selon le mode de réalisation de l'invention. Il apparaît que sa forme reste simple et conventionnelle, sans aucun relief au-delà de la surface extérieure, qui serait complexe à fabriquer. Au contraire, la zone de réception d'une bague de liaison 10, notamment la zone 31 destinée à bloquer la surface de blocage 11 de ladite bague de liaison 10, présente une forme simple réalisée en creux dans l'épaisseur de la paroi du bas de coque 30.
This construction has the following advantages:
  • The rotational surface 12 around which the collar is in rotational movement is enlarged with respect to the most common solutions which rest on a single screw similar for example to the screw 18 of the embodiment, which fulfills the function of axis of rotation. rotation of the collar relative to the bottom of the shell. With the solution according to the invention, the circular cross section of the rotating surface may have a diameter greater than or equal to 1.5 cm, preferably greater than or equal to 1.9 cm, and a thickness of between 0.2 and 1 cm. centimeter, preferably 0.4 centimeters. This sharp increase in the rotational surface makes it possible to achieve a better transmission of the skier's efforts towards the ski, and a more stable movement of the collar, in particular by reducing the play;
  • The shell bottom 30 and the collar 20 have relatively simple shapes. Their openings 24, 31 to receive the ring 10 are obtained by machining, after their formation by a conventional injection method or directly by molding using a suitable mold. The figure 6 thus illustrates the shell bottom 30 according to the embodiment of the invention. It appears that its shape remains simple and conventional, without any relief beyond the outer surface, which would be complex to manufacture. On the contrary, the receiving zone of a connecting ring 10, in particular the zone 31 intended to block the locking surface 11 of said connecting ring 10, has a simple shape hollowed out in the thickness of the bottom wall. of hull 30.

Selon une variante de réalisation, la bague de liaison 10 peut aussi permettre le réglage latéral de l'inclinaison du collier 20 relativement au bas de coque 30, par rapport à un plan longitudinal vertical, afin d'optimiser la prise de carre et/ou de compenser une morphologie spécifique du skieur. Cette inclinaison est aussi souvent dénommée par l'expression anglo-saxonne de « canting ». Pour cela, la bague de liaison 10 présente une architecture excentrée, c'est-à-dire que le centre o de l'ouverture traversante 14 de la bague de liaison 10 et de sa surface de blocage 11 ne coïncide pas avec le centre c de la surface de rotation 12, disposé sur l'axe de rotation 15 autour duquel tourne le collier 20, comme représenté sur les figures 7a à 7c. Ainsi, selon l'orientation de la surface de blocage 11 de la bague de liaison 10 au sein du bas de coque 30, selon quatre possibilités dans le cas de la section carrée envisagée sur une bague de liaison à architecture excentrée, quatre positions différentes du collier 20 relativement au bas de coque sont obtenues, puisque le centre c de rotation de ce collier peut occuper quatre positions différentes autour du centre o de l'ouverture traversante 14. Ainsi, cette solution permet la mise en oeuvre d'un procédé de réglage, qui comprend le retrait de la bague de liaison par dévissage de la vis 18, la rotation selon le ou les quart(s) de tour choisi(s) par le skieur de la bague de liaison, puis sa fixation par la vis 18 selon cette nouvelle orientation. Un autre type d'élément mécanique assurant la fixation de la bague de liaison avec le bas de coque pourrait être envisagé, du type d'un encliquetage facilement démontable.According to an alternative embodiment, the connecting ring 10 may also allow the lateral adjustment of the inclination of the collar 20 relative to the shell bottom 30, with respect to a vertical longitudinal plane, in order to optimize the edge grip and / or to compensate for a specific morphology of the skier. This inclination is also often referred to by the Anglo-Saxon expression "canting". For this, the connecting ring 10 has an eccentric architecture, that is to say that the center o of the through opening 14 of the connecting ring 10 and its blocking surface 11 does not coincide with the center c of the rotational surface 12, disposed on the axis of rotation around which the collar 20 rotates, as shown in FIGS. Figures 7a to 7c . Thus, according to the orientation of the locking surface 11 of the connecting ring 10 within the shell bottom 30, according to four possibilities in the case of the square section envisaged on an eccentric architecture connecting ring, four different positions of the collar 20 relative to the shell bottom are obtained, since the center of rotation of this collar can occupy four different positions around the center o of the through opening 14. Thus, this solution allows the implementation of a control method , which comprises removing the connecting ring by unscrewing the screw 18, the rotation according to the the quarter turn (s) chosen (s) by the skier of the connecting ring, then its attachment by the screw 18 according to this new orientation. Another type of mechanical element for fixing the connecting ring with the bottom of the shell could be envisaged, of the type of a snap easily removable.

Les figures 8a à 8c illustrent une bague de liaison selon une autre configuration, dans laquelle l'excentricité décrite précédemment, c'est-à-dire le décalage entre le centre o de l'ouverture traversante de la surface de blocage 11 et le centre c de la surface de rotation 12, est simplement réduite. Cela permet un réglage de canting de moindre amplitude, plus fin. A titre comparatif, les figures 9a à 9c illustrent la bague de liaison non excentrée, telle que déjà décrite précédemment en référence aux figures 2 à 5. Un skieur peut disposer des trois bagues de liaison pour sa chaussure, et choisir ainsi la bague de liaison qui lui semble adaptée à l'utilisation prévue de sa chaussure de ski. Cela lui apporte de la flexibilité sur les réglages possibles du canting de sa chaussure.The Figures 8a to 8c illustrate a connecting ring according to another configuration, wherein the eccentricity described above, that is to say the offset between the center o of the through opening of the blocking surface 11 and the center c of the surface of rotation 12, is simply reduced. This allows a lower amplitude, finer canting setting. By way of comparison, Figures 9a to 9c illustrate the non-eccentric connecting ring, as already described above with reference to Figures 2 to 5 . A skier can have the three connecting rings for his shoe, and thus choose the binding ring which seems to him adapted to the intended use of his ski boot. This gives him flexibility on the possible settings of the canting of his shoe.

Les bagues prévues par le mode de réalisation de l'invention permettent un réglage de l'inclinaison latérale ou canting du collier :

  • de 0°, position neutre illustrée par la bague de liaison des figures 9a à 9c ;
  • de 0,5°, réglage d'inclinaison intermédiaire illustré par les figures 8a à 8c ;
  • jusqu'à 1°, inclinaison maximale pouvant être atteinte et illustrée par les figures 7a à 7c. Des réglages d'inclinaison plus importante pourront être atteint par des bagues plus excentrées sans sortir du cadre de l'invention.
The rings provided by the embodiment of the invention allow adjustment of the lateral inclination or canting of the collar:
  • 0 °, neutral position illustrated by the connecting ring of the Figures 9a to 9c ;
  • 0.5 °, intermediate inclination adjustment illustrated by the Figures 8a to 8c ;
  • up to 1 °, maximum inclination that can be reached and illustrated by Figures 7a to 7c . Adjustments of greater inclination can be achieved by more eccentric rings without departing from the scope of the invention.

Finalement, avec la solution selon cette variante de réalisation de l'invention, la chaussure de ski peut être fabriqué sans surcoût, selon un procédé conventionnel, et présente l'avantage d'une meilleure performance par une surface de rotation agrandie du collier, tout en offrant la possibilité d'un réglage de canting simple à mettre en oeuvre et une tenue mécanique de l'ensemble est assurée par la surface de blocage de la bague insérée dans une forme creusée dans les côtés latéraux du bas de coque.Finally, with the solution according to this embodiment of the invention, the ski boot can be manufactured without additional cost, according to a conventional method, and has the advantage of better performance by an enlarged rotation surface of the collar, while by providing the possibility of a simple canting setting to implement and a mechanical strength of the assembly is provided by the blocking surface of the ring inserted into a shape dug in the lateral sides of the shell bottom.

La bague de liaison telle que décrite précédemment pourra être utilisée sur chaque côté latéral de la chaussure, ou en variante sur un seul côté, l'autre côté pouvant être équipé d'une liaison différente conventionnelle. De même, des bagues plus ou moins excentrées pourront être utilisées en combinaison, comme par exemple une bague à 0°, bague neutre, sur l'un des côtés latéraux de la chaussure, en combinaison d'une bague à 0,5° sur l'autre côté latéral de la chaussure. Une multitude de possibilités de réglage de l'inclinaison du collier est ainsi possible.The connecting ring as described above can be used on each lateral side of the shoe, or alternatively on one side, the other side can be equipped with a different conventional connection. Similarly, more or less eccentric rings may be used in combination, such as for example a 0 ° ring, neutral ring, on one of the lateral sides of the shoe, in combination with a ring at 0.5 ° on the other side of the shoe. A multitude of possibilities for adjusting the inclination of the collar is thus possible.
