Abstract

A winter sports boot comprises a rigid core (2) and a more supple main covering (11, 12). The core has reinforcing elements (3, 4, 5, 6, 7) which are not covered by the supple material. The rigid core is in the form of a shell with an articulated collar, and the reinforcing elements are situated at the back of the collar, at the sides and back of the heel and at the sides of the toes; the latter act as post deflectors. The reinforcing elements can have vibration dampers, and the rigid and supple components of the boot can be made separately and assembled subsequently by over-molding.

Description

La présente invention concerne une chaussure de sport, en particulier pour planche de glisse telle que ski, surf, ou chaussure de patinage, ayant d'une part une âme rigide constituant, dans certaines zones, la face intérieure de la chaussure qui reçoit un chausson, et d'autre part d'une enveloppe de matière souple recouvrant l'âme rigide et constituant elle-même la face intérieure de la chaussure dans les zones où l'âme rigide est absente.The present invention relates to a sports shoe, in particular for gliding boards such as skiing, surf, or skating shoe, having on the one hand a rigid core constituting, in certain areas, the face inside of the shoe which receives a slipper, and on the other hand an envelope of flexible material covering the rigid core and itself constituting the inside of the shoe in areas where the core rigid is absent.

De telles chaussures de sport sont connues dans l'art antérieur, par exemple dans les brevets FR 2.119.653 et US 5,588,228.Such sports shoes are known in the art earlier, for example in patents FR 2,119,653 and US 5,588,228.

Le brevet FR 2.119.653 décrit une chaussure de ski qui comprend une partie intérieure rigide et une partie extérieure souple. La partie intérieure rigide de cette chaussure a la forme d'une coque continue destinée à entourer entièrement le pied du skieur et la partie extérieure, résistante à l'usure et à l'abrasion, est destinée à protéger la partie intérieure de la chaussure.Patent FR 2,119,653 describes a ski boot which includes a rigid inner part and a part flexible exterior. The rigid inner part of this shoe has the shape of a continuous shell intended for completely surround the skier's foot and the part exterior, resistant to wear and abrasion, is intended to protect the inner part of the shoe.

Le brevet US 5,588,228 décrit une chaussure de ski comportant une âme rigide découpée de manière à former une structure rigide triangulée en deux parties, dont une partie forme la coque de la chaussure et l'autre partie le collier de la chaussure. Cette âme rigide de la chaussure est recouverte par une enveloppe souple, l'attachement entre l'âme et l'enveloppe souple se faisant lors de l'injection ou par des moyens mécaniques. Les armatures rigides de la chaussure constituent une structure rigide triangulée dont le rôle est une transmission optimale des efforts entre la jambe et la fixation. L'âme rigide triangulée de la coque a la forme générale d'un "Y" inversé, dont l'une des branches est dirigée vers l'avant de la chaussure, l'autre branche est dirigée en direction du talon de la chaussure et le pied du "Y" est relié au collier de la chaussure. Les efforts sont ainsi répartis sur l'avant de la chaussure et sur son talon, qui sont les endroits où la chaussure est également fixée aux skis dans le cas d'une chaussure de ski.US Patent 5,588,228 describes a ski boot comprising a rigid core cut so as to form a rigid structure triangulated in two parts, of which one part forms the shell of the shoe and the other part of the shoe collar. This rigid soul of the shoe is covered by a flexible envelope, the attachment between the core and the flexible envelope is doing during injection or by means mechanical. The rigid frames of the shoe constitute a triangular rigid structure whose role is an optimal transmission of forces between the leg and fixation. The rigid triangulated soul of the shell has the general shape of an inverted "Y", one of which of the branches is directed towards the front of the shoe, the other branch is directed towards the heel of the shoe and the foot of the "Y" is connected to the collar of the shoe. The efforts are thus distributed over the front of the shoe and on his heel, which are the places where the boot is also attached to the skis in the case of a ski boot.

Le but de la présente invention est d'améliorer les chaussures de sport connues dans l'état de la technique.The aim of the present invention is to improve the sports shoes known in the state of technical.

La présente invention a plus particulièrement pour but d'améliorer une chaussure dont l'âme rigide est directement en contact avec le chausson en augmentant les efforts transmis et en améliorant la précision du guidage.The object of the present invention is more particularly to improve a shoe whose rigid core is directly in contact with the liner increasing the transmitted forces and improving the accuracy of the guidance.

La chaussure selon l'invention est une chaussure à forte rigidité, typée compétition, dont l'âme rigide est en contact direct avec le chausson entourant le pied de l'utilisateur. Elle est caractérisée en ce que l'âme rigide comporte des moyens de renforcement qui ne sont pas recouverts par l'enveloppe en matière souple.The shoe according to the invention is a shoe with high rigidity, competitive type, whose rigid core is in direct contact with the liner surrounding the user's foot. It is characterized in that the rigid core includes reinforcing means which do not are not covered by the flexible material envelope.

La chaussure selon l'invention se distingue des chaussures de l'art antérieur en ce qu'elle comporte trois zones différentes, à savoir une zone souple, une zone rigide et une zone rigide et renforcée.The shoe according to the invention is distinguished from prior art footwear in that it comprises three different zones, namely a flexible zone, a rigid zone and a rigid and reinforced zone.

Elle présente en outre l'avantage de créer un contact direct entre l'âme rigide et le chausson ce qui augmente la précision du guidage.It also has the advantage of creating contact direct between the rigid core and the liner which increases guidance accuracy.

Les moyens de renforcement sont placés aux endroits de la chaussure transmettant des efforts importants et ils forment une structure générale en hauban améliorant l'appui arrière et la transmission des efforts latéraux. En fonction de leur emplacement sur la chaussure, les moyens de renforcement peuvent également avoir un effet de protection de celle-ci.The reinforcing means are placed at the places of the shoe transmitting significant forces and they form a general guy structure improving rear support and transmission of forces lateral. Depending on their location on the shoe, the reinforcing means can also have a protective effect of it.

Selon un premier mode d'exécution les moyens de renforcement comportent un renforcement sur l'arrière du collier et un renforcement sur l'arrière de la coque de la chaussure.According to a first embodiment, the means of reinforcement include reinforcement on the back of the collar and a reinforcement on the back of the shell of the shoe.

Selon un deuxième mode d'exécution, les moyens de renforcement comprennent en outre une bande de renforcement diagonale sur au moins un côté de la chaussure. La bande de renforcement est composée de deux parties, dont l'une est située sur la coque et l'autre sur le collier de la chaussureAccording to a second embodiment, the means of reinforcement further include a strip of diagonal reinforcement on at least one side of the shoe. The reinforcing strip is composed of two parts, one of which is located on the hull and the other on the shoe collar

Selon une variante du deuxième mode d'exécution, les moyens de renforcement comprennent une bande de renforcement diagonale sur chaque côté de la chaussure.According to a variant of the second embodiment, the reinforcement means include a strip of diagonal reinforcement on each side of the shoe.

Selon un troisième mode d'exécution, la chaussure comprend un renfort sur l'un au moins des côtés avant de la coque de la chaussure formant un déflecteur de piquets.According to a third embodiment, the shoe includes a reinforcement on at least one of the front sides of the shell of the shoe forming a deflector of stakes.

Selon un quatrième mode d'exécution, les moyens de renforcement comportent en outre un élément amortisseur de vibrations.According to a fourth embodiment, the means of reinforcement further comprises a damping element vibrations.

Selon une autre variante, la chaussure est une chaussure de type monobloc. Dans cette variante, l'enveloppe en matière souple permet de créer des zones d'articulation sur la chaussure.According to another variant, the shoe is a monobloc type shoe. In this variation, the flexible material envelope creates zones of articulation on the shoe.

L'invention concerne également un procédé de fabrication d'une chaussure. Selon un premier mode d'exécution du procédé, l'âme rigide et l'enveloppe en matière souple sont fabriquées séparément et assemblées par encastrement des deux parties.The invention also relates to a method of manufacture of a shoe. According to a first mode of execution of the process, the rigid core and the envelope flexible material are manufactured separately and assembled by embedding the two parts.

Selon un second mode d'exécution du procédé, l'âme rigide et l'enveloppe en matière souple sont assemblées par surmoulage.According to a second embodiment of the method, the core rigid and the flexible material envelope are assembled by overmolding.

Le fait que les moyens de renforcement ne soient pas recouverts par l'enveloppe en matière souple présente, d'une part, l'avantage de ne pas créer de surépaisseur de matière sur la chaussure aux endroits où ils sont placés et, d'autre part, de jouer le rôle de protections en slalom. De telles surépaisseurs peuvent en effet gêner l'utilisateur par un frottement répété de ces moyens les uns contre les autres, en particulier dans le cas de bandes de renforcement diagonales placées sur le côté intérieur des chaussures. D'autre part, la partie souple peut être endommagée si elle recouvre le renfort de l'avant de la chaussure qui sert de déflecteur de piquet.The fact that the means of reinforcement are not covered by the flexible material envelope present, on the one hand, the advantage of not creating any extra thickness material on the shoe where they are placed and, on the other hand, to play the role of protections in slalom. Such extra thicknesses can indeed annoy the user by repeated friction of these means against each other, in particular in the case of diagonal reinforcement strips placed on the inside of the shoes. Else apart, the flexible part can be damaged if it covers the reinforcement on the front of the shoe that serves of stake deflector.

L'invention sera mieux comprise grâce à la description d'un mode d'exécution non-limitatif et des dessins qui s'y rapportent.The invention will be better understood thanks to the description a non-limiting embodiment and drawings which relate to it.

La figure 1 est une vue de côté en perspective de l'âme rigide d'une chaussure selon l'invention.Figure 1 is a perspective side view of the core rigid shoe according to the invention.

La figure 2 est une vue arrière en perspective de l'âme rigide d'une chaussure selon l'invention.Figure 2 is a rear perspective view of the core rigid shoe according to the invention.

La figure 3 est une vue de côté en perspective d'une chaussure selon l'invention dont l'âme est recouverte par l'enveloppe en matière souple.Figure 3 is a perspective side view of a shoe according to the invention whose soul is covered by the flexible material envelope.

La figure 4 est une vue arrière en perspective d'une chaussure selon l'invention dont l'âme est recouverte par l'enveloppe en matière souple.Figure 4 is a rear perspective view of a shoe according to the invention whose soul is covered by the flexible material envelope.

L'âme de la chaussure est décrite tout d'abord en référence aux figures 1 et 2.The soul of the shoe is first described in reference to Figures 1 and 2.

Cette âme se compose d'une coque 1 ajourée destinée à supporter et à transmettre les efforts du pied du skieur vers le ski et d'un collier 2 articulé sur la coque 1 et supportant la cheville du skieur. La coque 1 comprend en outre deux renforts latéraux 4 et 9, un renfort arrière 5 placé à la hauteur du talon, et deux renforts avant 3 et 8. Les renforts avant 3 et 8 sont utilisés en particulier comme déflecteurs de piquets et protègent la coque de la chaussure lors des chocs contre des piquets de slalom, par exemple. Les renforts latéraux 4, 9 et le renfort arrière 5 de la coque 1 sont prolongés sur le collier 2 par des renforts correspondants 6, 10 et 7. Les renforts latéraux 4, 6, 9 et 10 forment une bande diagonale de chaque côté de la chaussure qui augmente la rigidité latérale de la chaussure. Les renforts arrières 5 et 7 permettent quant à eux de rigidifier l'appui sur le talon du skieur et ils sont prolongés par la semelle de la chaussure.This core consists of an openwork shell 1 intended for bear and transmit the efforts of the foot of the skier to ski and a collar 2 articulated on the shell 1 and supporting the skier's ankle. Hull 1 further includes two side reinforcements 4 and 9, one rear reinforcement 5 placed at heel height, and two front reinforcements 3 and 8. Front reinforcements 3 and 8 are used in particular as stake deflectors and protect the shell of the shoe during shocks against slalom poles, for example. The reinforcements side 4, 9 and the rear reinforcement 5 of the shell 1 are extended on the collar 2 by reinforcements correspondents 6, 10 and 7. The lateral reinforcements 4, 6, 9 and 10 form a diagonal band on each side of the shoe which increases the lateral stiffness of the shoe. The rear reinforcements 5 and 7 allow as for them to stiffen the support on the heel of the skier and they are extended by the sole of the shoe.

L'âme de la chaussure représentée dans les figures 1 et 2 constitue la partie la plus rigide de la chaussure et les renforts forment des haubans qui, grâce à leur résistance à la traction, améliorent l'appui arrière de la chaussure. La position de ces haubans sur les faces latérales de la chaussure permet une bonne répartition des efforts et augmente la précision du guidage de la chaussure. En effet, les efforts longitudinaux sont repris principalement par les renforts arrières 5, 7 et également par les renforts latéraux 4, 6, 9, 10, et les efforts latéraux par les renforts latéraux 4 et 6 ou 9 et 10.The soul of the shoe represented in FIGS. 1 and 2 constitutes the most rigid part of the shoe and the reinforcements form stay cables which, thanks to their tensile strength, improve rear support by the shoe. The position of these shrouds on the faces side of the shoe allows good distribution efforts and increases the precision of the guidance of the shoe. In fact, the longitudinal forces are mainly taken up by the rear reinforcements 5, 7 and also by the side reinforcements 4, 6, 9, 10, and the lateral forces by lateral reinforcements 4 and 6 or 9 and 10.

Les figures 3 et 4 représentent deux vues d'une chaussure dont la coque 1 et le collier 2 sont partiellement recouverts par les enveloppes en matière souple 11 et 12. Les renforts latéraux 4, 9, 6, 10 et arrières 5, 7 ne sont pas recouverts par les enveloppes en matière souple. Ils sont par conséquent visibles et sont hachurés sur les figures. Les parties souples 11, 12 recouvrent le dessus du pied et l'avant de la jambe de l'utilisateur, parties de la chaussure qui n'ont pas besoin d'être aussi rigide que le reste de la chaussure.Figures 3 and 4 show two views of a shoe whose shell 1 and collar 2 are partially covered by the material envelopes flexible 11 and 12. The lateral reinforcements 4, 9, 6, 10 and rear 5, 7 are not covered by the envelopes in flexible material. They are therefore visible and are hatched in the figures. The flexible parts 11, 12 cover the top of the foot and the front of the leg of the user, parts of the shoe which have not need to be as rigid as the rest of the shoe.

Les boucles permettant de fermer la chaussure ne sont pas représentées dans les figures. Ces boucles sont de type classique et elles sont fixées à la partie rigide de la chaussure.The buckles used to close the shoe are not not shown in the figures. These loops are from classic type and they are fixed to the rigid part of the shoe.

La chaussure est fabriquée avec les matières habituelles, par exemple en polyuréthane avec une dureté de 64 shD pour la partie rigide et 50 shD pour l'enveloppe en matière souple.The shoe is made with the materials usual, for example polyurethane with a hardness of 64 shD for the rigid part and 50 shD for the envelope in flexible material.

Les moyens de renforcement peuvent être formés lors du moulage de la coque 1 et du collier 2 en prévoyant une surépaisseur de matière aux endroits déterminés dans le moule. Les moyens de renforcement peuvent également être fixés après le moulage par des moyens de fixation mécanique, comme par exemple des vis ou autres moyens équivalents. Ainsi, en cas d'usure prématurée, en particulier pour les déflecteurs avant, les renforts pourraient être changés. De même, différents renforts latéraux avec des rigidités différentes pourraient être prévus de manière que l'utilisateur de la chaussure ait le choix entre plusieurs modèle et puisse les changer ou les ajuster. Les moyens de renforcement n'étant pas recouverts par la partie souple 11 et 12, leur changement ou leur remplacement est facilité.Reinforcement means can be formed during molding of the shell 1 and of the collar 2 by providing a excess material at the locations determined in the mold. Reinforcement means can also be fixed after molding by fixing means mechanical, such as screws or other means equivalent. Thus, in the event of premature wear, especially for front deflectors, reinforcements could be changed. Likewise, different reinforcements lateral with different rigidities could be designed so that the user of the shoe has the choice between several models and can change them or adjust them. Reinforcement means not being covered by the flexible part 11 and 12, their change or replacement is facilitated.

Il peut en outre être avantageux de fixer des éléments amortisseurs de vibrations sur les moyens de renforcement. De tels éléments amortisseurs de vibration ont été décrits en détail dans le brevet FR 2 706 741 au nom du demandeur. Ils se composent principalement d'un matériau viscoélastique associé à une pièce rigide de contrainte, la pièce de contrainte étant fixée aux moyens de renforcement par l'intermédiaire du matériau viscoélastique.It may also be advantageous to fix elements vibration dampers on the means of enhancement. Such shock absorbing elements vibration have been described in detail in patent FR 2 706 741 in the name of the applicant. They consist mainly of a viscoelastic material associated with a rigid restraint, the restraint being attached to the reinforcing means by through the viscoelastic material.

La pièce rigide de contrainte a un module d'élasticité E supérieur à 104 MPa et son matériau est choisi dans le groupe contenant les alliages d'aluminium ou d'aluminium-zinc, magnésium, les matériaux thermodurcissables stratifiés armés de fibres de verre ou de carbone et les matériaux thermoplastiques armés de fibres de verre ou de carbone. Le matériau viscoélastique est par exemple un caoutchouc butyle ou un élastomère de synthèse, utilisés seuls, en mélange Ou encore chargés.The rigid constraint part has a modulus of elasticity E greater than 10 4 MPa and its material is chosen from the group containing aluminum or aluminum-zinc alloys, magnesium, thermosetting laminated materials reinforced with glass fibers or carbon and thermoplastic materials reinforced with glass fibers or carbon. The viscoelastic material is for example a butyl rubber or a synthetic elastomer, used alone, as a mixture, or else charged.

L'invention peut également s'appliquer aux chaussures de sport mono-bloc dans lesquelles la coque et le collier forment une seule pièce. Des moyens de renforcement similaires à ceux décrits précédemment peuvent être prévus sur de telles chaussures mono-bloc de manière à constituer cette structure particulière en hauban. Dans de telles chaussures mono-bloc, l'axe d'articulation entre la coque et le collier est remplacé par l'enveloppe en matière souple qui crée des zones d'articulation.The invention can also be applied to shoes mono-block sports in which the hull and necklace form one piece. Means of reinforcement similar to those described above can be provided on such mono-block shoes so as to constitute this particular structure in guy line. In such mono-block shoes, the axis articulation between the shell and the collar is replaced by the flexible material shell which creates articulation zones.

L'âme rigide et l'enveloppe en matière souple sont fabriquées par des procédés classiques de l'état de la technique tels que l'injection ou la multi-injection.
