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, especially for a gliding board such as ski, surfing, or skating shoe, having on the one hand a rigid core constituting, in certain areas, the face interior of the shoe that receives a slipper, and on the other hand a flexible material envelope covering the rigid soul and constituting itself the inner face of the shoe in areas where the soul 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 prior art, for example in FR 2,191,653 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 2,191,653 describes a ski boot which includes a rigid inner part and a part flexible outdoor. 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 discloses a ski boot having a rigid core cut to form a rigid structure triangulated in two parts, of which one part forms the shell of the shoe and the other part the collar of the shoe. This rigid soul of the shoe is covered by a flexible envelope, the attachment between the soul and the flexible envelope is doing while injecting or by means mechanical. Rigid frames of the shoe constitute a triangulated rigid structure whose role is an optimal transmission of efforts between the leg and fixation. The rigid triangulated soul of the shell has the general shape of an inverted "Y", one of which branches are 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 on the front of the shoe and on his heel, which are the places where the shoe 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 object of the present invention is to improve the sports shoes known in the state of the 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 present invention more particularly aims to improve a shoe whose rigid soul is directly in contact with the slipper by increasing the efforts transmitted and by improving the accuracy of guide.

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 strong rigidity, typical competition, whose rigid soul is in direct contact with the slipper surrounding the foot of the user. It is characterized in that the rigid core comprises reinforcing means which does 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 shoes of the prior art in that it comprises three different zones, namely a flexible zone, a rigid area and a rigid and reinforced area.

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 a contact direct between the rigid soul and the slipper what increases the precision of the guidance.

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 reinforcement means are placed at the places of the shoe transmitting significant effort and they form a general structure in guying improving back support and transmission of efforts side. Depending on their location on the shoe, the means of reinforcement 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 have reinforcement on the back collar and reinforcement on the back of the hull 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 band of diagonal reinforcement on at least one side of the shoe. The reinforcing tape is composed of two parts, one of which is located on the hull and the other on the collar of the shoe

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 means of reinforcement include a band 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 the hull 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 furthermore comprise a damping element of 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 monoblock type shoe. In this variant, 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 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 soul 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 reinforcement means are not covered by the envelope of flexible material present, on the one hand, the advantage of not creating extra thickness of material on the shoe where they are placed and, on the other hand, to play the role of slalom protections. Such extra thicknesses can indeed, annoy the user by repeated friction of these means against each other, especially in the case of diagonal reinforcement strips placed on the inner side of the shoes. Else on the other hand, the flexible part can be damaged if it covers the reinforcement of the front of the shoe that serves 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.

  • 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.
    • The invention will be better understood thanks to the description of a non-limiting embodiment and related drawings.
  • Figure 1 is a perspective side view of the rigid core of a shoe according to the invention.
  • Figure 2 is a rear perspective view of the rigid core of a shoe according to the invention.
  • Figure 3 is a perspective side view of a shoe according to the invention, the core is covered by the envelope of flexible material.
  • Figure 4 is a rear perspective view of a shoe according to the invention, the core is covered by the envelope of flexible material.

    • 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 soul consists of a pierced shell 1 intended for support and transmit the efforts of the skier to the ski and a collar 2 articulated on the shell 1 and supporting the skier's ankle. The hull 1 further comprises two lateral reinforcements 4 and 9, a rear reinforcement 5 placed at the height of the heel, and two reinforcements before 3 and 8. Reinforcements before 3 and 8 are used especially as stake deflectors and protect the shell of the shoe during shocks against slalom stakes, for example. The reinforcements 4, 9 and the rear reinforcement 5 of the hull 1 are extended on the collar 2 by reinforcements corresponding ones 6, 10 and 7. The lateral reinforcements 4, 6, 9 and 10 form a diagonal band on each side of the shoe that increases the lateral rigidity of the shoe. 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 shown in FIGS. 2 is the stiffest part of the shoe and the reinforcements form stay cables which, thanks to their tensile strength, improve the back support of the shoe. The position of these guys on the faces side of the shoe allows a good distribution efforts and increases the accuracy of guiding the shoe. Indeed, the longitudinal forces are taken up mainly by the rear reinforcements 5, 7 and also by the lateral 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 envelopes made of 11 and 12. The lateral reinforcements 4, 9, 6, 10 and backs 5, 7 are not covered by envelopes in flexible matter. They are therefore visible and are hatched on 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 that do not have 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 loops for closing the shoe are not not shown in the figures. These loops are from classic type and they are attached 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 of materials usual, for example polyurethane with a hardness of 64 shD for the rigid part and 50 shD for the envelope of 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.The reinforcement means may be formed during the molding of the shell 1 and collar 2 by providing a thickness of material at the locations determined in the mold. The reinforcement means can also to be fixed after molding by fastening means mechanical, such as screws or other means equivalents. Thus, in case of premature wear, especially for front baffles, reinforcements could be changed. Similarly, various reinforcements side with different rigidities could be provided in such a way that the user of the shoe has the choice between several models and can change them or adjust them. The reinforcement means not being covered by 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.In addition, it may be advantageous to fix vibration dampers on the means of enhancement. Such damping elements of vibration have been described in detail in the FR 2 patent 706,741 in the name of the applicant. They consist of mainly of a viscoelastic material associated with a rigid piece of constraint, the piece of constraint being attached to the reinforcement means by via 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 piece of stress has a modulus of elasticity E greater than 10 4 MPa and its material is selected from the group containing aluminum alloys or aluminum-zinc, magnesium, laminated thermosetting materials reinforced with fiberglass or of carbon and thermoplastic materials reinforced with fiberglass or carbon. The viscoelastic material is for example a butyl rubber or a synthetic elastomer, used alone, as a mixture or else loaded.

    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 single-block sports car in which the hull and the necklace form one piece. Means of reinforcement similar to those previously described can be provided on such mono-block shoes in order to constitute this particular structure in guy. In such mono-block shoes, the axis articulation between the shell and the collar is replaced by the flexible material envelope which creates articulation areas.

    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.
