Abstract
Description
La présente invention concerne une languette semi-rigide pour une chaussure de sport à tige haute, en particulier une chaussure de sport de glisse, et plus particulièrement une chaussure pour la pratique du surf à neige, comportant un renfort s'étendant du dessus du pied jusqu'au-dessus de la cheville.The present invention relates to a semi-rigid tongue for a high-top sports shoe, especially a sliding sports shoe, and more especially a shoe for surfing with a reinforcement extending from above the foot to above the ankle.
Les premières chaussures de ski, en cuir, étaient relativement souples. Elles offraient un bon confort. Afin d'assurer une bonne transmission des efforts entre le pied et le ski, c'est à dire de réduire la capacité de déformation de la chaussure, la semelle et la tige de la chaussure sont devenues de plus en plus rigides, devenant en conséquence de moins en moins confortables. Avec l'apparition des chaussures en matière plastique équipée d'un chausson de confort, les chaussures et donc les tiges et les languettes sont devenues particulièrement rigides. Pour ce faire, les languettes comportent un renfort. Depuis un certain nombre d'années, on cherche à améliorer le confort des chaussures de ski, on cherche en particulier à améliorer le confort des languettes.The first ski boots, in leather, were relatively flexible. They offered good comfort. In order to ensure a good transmission of the forces between foot and skiing, that is to say to reduce the capacity deformation of the shoe, the sole and the upper shoes have become more and more rigid, as a result becoming less and less comfortable. With the appearance of plastic shoes fitted with a comfort slipper, shoes and so the rods and the tabs became particularly rigid. To do this, the tabs have a reinforcement. For a number years, we seek to improve the comfort of ski boots, we are looking in particular at improve the comfort of the tabs.
On connaít du brevet US 5 647 146, une languette pour chausson de confort de chaussure de ski réalisée en deux parties. La partie supérieure coulisse sur la partie inférieure afin d'offrir une hauteur de languette réglable. Ceci permet au skieur d'adapter le chausson à sa façon de skier et à ses sensations.We know from US Patent 5,647,146, a tab for ski boot comfort liner made of two parts. The upper part slides on the lower part to provide a height of adjustable tongue. This allows the skier to adapt the slipper in its way of skiing and its sensations.
On connaít d'une demande WO 01/49142, une chaussure de surf présentant une languette munie d'un renfort ayant des rigidités différentes selon différents axes de flexion de part et d'autre du tibia, permettant ainsi de tenir compte des rôles différents que jouent les flexions de la jambe vers l'extérieur ou vers l'intérieur.We know from a request WO 01/49142, a shoe surf having a tongue provided with a reinforcement having different rigidities along different axes of flexion on either side of the tibia, thus allowing to take into account the different roles that leg bends outward or toward inside.
On connaít du brevet US 4 470 206, une chaussure de ski munie d'une languette présentant un renfort de rigidité réglable. Ce renfort est constitué de deux parties de formes complémentaires. La rigidité du renfort peut être modifiée en enlevant une partie amovible.We know from US Patent 4,470,206, a ski boot provided with a tongue having a stiffness reinforcement adjustable. This reinforcement consists of two parts of complementary forms. The stiffness of the reinforcement can be modified by removing a removable part.
On connaít de la demande WO 00/33692, une languette de chaussure de surf présentant un renfort fixé à une seule de ses extrémités. L'autre extrémité peut se déplacer dans un logement prévu sur la languette. Ce mode de liaison du renfort à la languette permet de supprimer le pli que fait la languette lors de la flexion de la jambe qui a pour conséquence, une compression dans la zone du cou-de-pied.We know from application WO 00/33692, a tongue of surf boot having a reinforcement attached to a only one of its ends. The other end can be move into a housing provided on the tongue. This mode of connection of the reinforcement to the tongue allows remove the crease that the tongue makes when bending of the leg which results in a compression in the instep area.
Ces inventions contribuent à adapter la chaussure et en particulier la languette à la morphologie du skieur. Cependant, malgré ces réglages et le rembourrage de confort entre la jambe et la languette, on ressent une ligne douloureuse sur le tibia au niveau du haut de la languette.These inventions help to adapt the shoe and especially the tongue to the morphology of the skier. However, despite these adjustments and the padding of comfort between the leg and the tongue, you feel painful line on the shin at the top of the tongue.
Le but de l'invention est de réaliser une languette pour une chaussure de sport à tige haute, en particulier, une chaussure de sport de glisse palliant cet inconvénient. En particulier, l'invention se propose de réaliser une languette pour chaussure avec laquelle, on ne ressent pas de ligne de compression douloureuse sur le tibia au niveau du haut de la languette.The object of the invention is to produce a tongue for a high-top sports shoe, particular, a sliding sports shoe overcoming this disadvantage. In particular, the invention is suggests making a shoe tongue with which one does not feel a compression line painful on the shin at the top of the tongue.
Par rigidité à la flexion, on entend rapport entre le moment fléchissant appliqué sur la languette et la déformation de la languette induite par ce moment fléchissant lors de la flexion de la jambe du skieur. Cette déformation est définie par rapport à la forme qu'occupe la languette au repos.By bending stiffness is meant the relationship between the bending moment applied to the tongue and tongue deformation induced by this moment flexing when bending the skier's leg. This deformation is defined with respect to the shape that the tongue occupies at rest.
La languette selon l'invention est caractérisée en ce qu'elle présente en haut de sa partie supérieure au centre, une zone de rigidité à la flexion inférieure à la rigidité à la flexion du reste de la languette et en ce que le renfort comprend un élément central et deux éléments latéraux travaillant conjointement. Grâce à une telle architecture du renfort, la plupart des efforts de la languette sur la jambe sont repris par les éléments latéraux exerçant une pression sur la jambe de part et d'autre du tibia et évitant ainsi une gêne ressentie par l'utilisateur qui serait due à une pression de la languette sur le tibia. The tongue according to the invention is characterized in that which it presents at the top of its upper part center, an area of flexural rigidity less than the bending stiffness of the rest of the tongue and that the reinforcement includes a central element and two side elements working together. Thanks to such reinforcement architecture, most tongue efforts on the leg are taken up by the side members exerting pressure on the leg on either side of the tibia and thus avoiding a discomfort felt by the user which would be due to a pressure of the tongue on the tibia.
Selon les modes de réalisation, le renfort présente au niveau du cou-de-pied une zone de rigidité à la flexion supérieure à la rigidité à la flexion du reste du renfort. Ainsi, la languette se déforme peu à cet endroit empêchant le pli de la languette provoquant une zone de pression douloureuse.According to the embodiments, the reinforcement present at instep level an area of flexural rigidity greater than the bending stiffness of the rest of the reinforcement. Thus, the tongue deforms little at this place preventing the fold of the tongue causing a painful pressure area.
Avantageusement, le renfort central a la forme d'une languette connue relativement souple s'étendant sensiblement moins haut que la languette finie. Il peut être moins rigide que les éléments latéraux.Advantageously, the central reinforcement has the form of a relatively flexible known tongue extending noticeably lower than the finished tongue. he can be less rigid than the side elements.
Les zones de différentes rigidités à la flexion sont obtenues par la variation de l'épaisseur du renfort et/ou par l'utilisation de matériaux différents. Les variations de l'épaisseur du renfort permettent de faire varier le moment quadratique du renfort ou de ses éléments. On peut encore utiliser des matériaux de différents modules d'élasticité pour faire varier la rigidité à la flexion du renfort ou de ses éléments. On peut, par exemple, utiliser un procédé de sur-injection pour réaliser le renfort ou ses éléments.The areas of different flexural stiffnesses are obtained by varying the thickness of the reinforcement and / or by the use of different materials. The variations in the thickness of the reinforcement allow vary the quadratic moment of the reinforcement or its elements. We can still use materials of different elastic moduli to vary the bending stiffness of the reinforcement or its elements. We can, for example, use an over-injection process to make the reinforcement or its elements.
Les deux éléments latéraux sont suffisamment rigides et
présentent une forme resserrée, au niveau du cou-de-pied
pour servir de renfort à la languette souple, et
écartée sur le haut pour éviter la pression d'un
élément rigide sur le tibia tout en présentant un bon
appui de chaque côté et au centre grâce à la
coopération des deux éléments latéraux rigides et de
l'élément central.
Cet élément central évite en effet aux éléments
latéraux de s'écarter l'un de l'autre, obligeant ceux-ci
à fléchir.The two lateral elements are sufficiently rigid and have a tight shape, at the instep to serve as reinforcement for the flexible tongue, and spread apart on the top to avoid the pressure of a rigid element on the tibia while presenting good support on each side and in the center thanks to the cooperation of the two rigid lateral elements and the central element.
This central element in fact prevents the lateral elements from moving away from each other, forcing them to flex.
Les éléments de renfort latéraux peuvent présenter, au niveau du cou-de-pied, une forme en S telle que ces éléments latéraux se rapprochent l'un de l'autre sur l'élément central.The lateral reinforcing elements may have, at the level of the instep, an S shape such that these side elements approach each other on the central element.
L'élément central et les éléments latéraux peuvent consister en une même pièce.The central element and the lateral elements can consist of one piece.
Dans ce cas, le renfort peut être fixé sur la face extérieure de la languette ou dans la languette.In this case, the reinforcement can be fixed on the face outside of the tongue or in the tongue.
Lorsque le renfort est constitué de plusieurs éléments, ces différents éléments peuvent être fixés sur la face extérieure de la languette et/ou dans la languette.When the reinforcement is made up of several elements, these different elements can be fixed on the face outside of the tongue and / or in the tongue.
Le renfort ou les différents éléments le constituant sont de préférence cousus ou collés sur la languette ou dans la languette.The reinforcement or the various elements constituting it are preferably sewn or glued on the tongue or in the tongue.
Le dessin annexé représente, à titre d'exemple, un mode de réalisation de l'invention.The accompanying drawing shows, by way of example, a mode for carrying out the invention.
La figure 1 est une vue développée d'une languette selon l'invention. Figure 1 is a developed view of a tab according to the invention.
La figure 2 est une vue développée, en coupe longitudinale de la languette selon le plan III-III de la figure 1.Figure 2 is a developed view, in section longitudinal of the tongue according to plane III-III of Figure 1.
La figure 3 est une vue développée de l'élément central du renfort.Figure 3 is a developed view of the central element reinforcement.
La figure 4 est une vue en plan d'un élément latéral du renfort.Figure 4 is a plan view of a side member of the reinforcement.
La figure 5 est une vue en perspective d'une chaussure munie d'une languette selon l'invention.Figure 5 is a perspective view of a shoe provided with a tab according to the invention.
La languette 10 représentée aux figures 1 et 2 comprend
un renfort constitué d'un élément central 2 et de deux
éléments latéraux 1. La face interne de la languette
10, étant en contact avec la chaussette de
l'utilisateur, est constituée d'une mousse 4 recouverte
d'un tricot 5.The
La face externe de la languette 10 est recouverte d'un
tricot 3 recouvrant l'élément central 2 du renfort et
la mousse 4 sur laquelle il est collé ou cousu. Une
couture 11 lie le tricot 3 à la mousse 4 autour de
l'élément central 2.The outer face of the
Sur le tricot 3, sont collés ou cousus les éléments
latéraux 1 du renfort. D'autres couches de matériaux,
par exemple une couche d'un matériau imperméable,
peuvent être ajoutées afin d'assurer diverses
fonctions. On knitting 3, the elements are glued or sewn
Cette languette 10 est destinée a équiper une chaussure
de surf 8 comme représenté à la figure 5. Elle vient en
effet obturer l'échancrure de laçage dont la fonction
est de permettre d'adapter la chaussure au pied de
l'utilisateur.This
Les divers éléments 1, 2 représentés aux figures 3 et 4
et constituant le renfort sont réalisés en matière
plastique. L'élément central 2 du renfort vient
sensiblement jusqu'en bas de la languette et s'arrête
sensiblement avant le haut de la languette 10. Il
présente dans la zone du cou-de-pied 6 une section
réduite.The
Les éléments latéraux 1 fixés de part et d'autre de
l'élément central 2, s'étendent du milieu de la partie
inférieure de la languette jusqu'en haut de la
languette. Dans la région 7 du cou-de-pied, ces
éléments latéraux présentent une forme en S de manière
à se rapprocher l'un de l'autre, ce qui a pour effet de
réduire la flexibilité de la languette au niveau du
cou-de-pied.The
Selon ce mode de réalisation, la languette ne présente
pas de renfort en haut de sa partie supérieure, au
centre. Ainsi, on aménage une zone 9 présentant une
rigidité à la flexion inférieure à la rigidité à la
flexion du reste de la languette 10 et on évite une
pression, source de gêne, de la languette sur le tibia
de l'utilisateur. According to this embodiment, the tongue does not have
no reinforcement at the top of its upper part,
center. Thus, a
Les efforts de la jambe du skieur sur la languette sont
repris sur les côtés de la languette, de part et
d'autre du tibia, où sont présents les éléments
latéraux 1 du renfort.The efforts of the skier's leg on the tongue are
shown on the sides of the tongue, on both sides and
on the other side of the tibia, where the elements are
La languette présente donc dans la région du cou-de-pied,
une zone de rigidité à la flexion supérieure à la
rigidité à la flexion du reste du renfort obtenue par
la coopération de la section de l'élément central 2 et
des formes particulières 7 des éléments latéraux de
renfort 1. Ces moyens permettent d'obtenir un moment
quadratique de la section du renfort tel que la
languette se déforme peu dans la région du cou-de-pied
lors de la flexion, empêchant le pli de la languette
provoquant à cet endroit, une zone de pression
douloureuse.The tongue therefore present in the instep region,
an area of flexural rigidity greater than the
bending stiffness of the rest of the reinforcement obtained by
the cooperation of the section of the
