Abstract

A composite flexible, permeable, matl. compressible in section incorporates a flexible sheet carrying on at least one face a number of separate deformable elements (1) perpendicular to the sheet surface. Pref. the elements (1) are cut or uncut loops of mechanically elastic filamentary matls., monofilament or multifilament, pref. of Nylon (RTM-polyamide) or polypropylene. Pref. the support layer has a core (3) 2-6 mm thick of open cell elastic (polyurethane) foam between layers (2,4) of strong flexible permeable (Jersey weave) fabric. Prod. is esp. suitable for insoles for shoes such as sports shoes: the vertical elements deform in proportion to local pressures on the matl. surface and also induce ventilation.

Description

L'invention est relative à une nouvelle structure composite en feuille. The invention relates to a new composite sheet structure.

Elle concerne également l'application de cette structure en feuille à la confection de semelles intérieures pour articles chaussants, notamment pour chaussures de sport. It also relates to the application of this sheet structure to the production of insoles for footwear, in particular for sports shoes.

La structure en feuille selon l'invention est caractérisée par le fait qu'elle comporte une base souple et perméable à l'air qui porte sur au moins une face une multitude d'éléments séparés déformables perpendiculairement au plan de la base. The sheet structure according to the invention is characterized in that it comprises a flexible and air-permeable base which carries on at least one face a multitude of separate deformable elements perpendicular to the plane of the base.

De préférence, les éléments séparés sont filiformes et, de préférence encore, ils sont constitués par des boucles. La hauteur des boucles peut être d'environ 3 mm. Ces éléments filiformes peuvent être constitués chacun par un fil monofilament ou par plusieurs fils monofilaments travaillés ensemble. Dans le premier cas, la densité de population est supérieure à celle du deuxième cas, dans lequel chaque boucle se divise d'elle-mdme en plusieurs boucles unitaires dont les pieds de liaison avec la base sont communs. Preferably, the separate elements are threadlike and, more preferably, they are constituted by loops. The height of the loops can be around 3 mm. These filiform elements may each consist of a monofilament thread or by several monofilament threads worked together. In the first case, the population density is higher than that of the second case, in which each loop divides of itself into several unitary loops whose feet of connection with the base are common.

Les boucles, qui sont portées par un support appartenant à la base, peuvent être obtenues par tout procédé approprié, par exemple par tissage ou tricotage, avec ou sans grattage. The loops, which are carried by a support belonging to the base, can be obtained by any suitable method, for example by weaving or knitting, with or without scraping.

En variante, les éléments filiformes peuvent être constitués par des fils, perpendiculaires au plan de la base, dont l'extrémité libre est élargie par exemple par traitement thermique. As a variant, the filiform elements can be formed by wires perpendicular to the plane of the base, the free end of which is widened, for example by heat treatment.

La matière constitutive des éléments filiformes est choisie pour pouvoir se déformer mécaniquement avec retour à l'état de repos. The material of the filiform elements is chosen to be able to deform mechanically with return to the state of rest.

Cette matière est avantageusement du Nylon ou du polypropylène. This material is advantageously nylon or polypropylene.

Quant à la base, elle comporte, outre le support ci-dessus qui porte les éléments séparés, au moins une couche d'un matériau souple et perméable à l'air, et de préférence également compressible. As for the base, it comprises, in addition to the above support which carries the separate elements, at least one layer of a flexible and breathable material, and preferably also compressible.

Suivant un mode de réalisation préféré, la base comporte, outre le support, une couche de mousse cellules ouvertes, par exemple à base de polyuréthane, et une nappe textile, la couche de mousse étant collée à chaud, par fusion partielle (procédé dit de "foamage"), sur le support et sur la nappe textile. According to a preferred embodiment, the base comprises, in addition to the support, a layer of open cell foam, for example based on polyurethane, and a textile sheet, the foam layer being glued hot, by partial melting (process known as "foamage"), on the support and on the textile tablecloth.

La couche de mousse peut avoir par exemple de 2 à 6 mm d'épaisseur.  The foam layer may for example be 2 to 6 mm thick.

La nappe textile est avantageusement un tricot jersey qui allie parfaitement les qualités de confort, de souplesse et d'aération. The textile tablecloth is advantageously a jersey knit which perfectly combines the qualities of comfort, flexibility and ventilation.

Dans son application à la confection d'articles chaussants, notamment de chaussures de sport, la structure en feuille selon l'invention présente des qualités exceptionnelles de confort et d'aération. I1 s'y ajoute un massage du pied de l'utilisateur, grâce au grand nombre de points d'appui constitués par les éléments séparés. In its application to the manufacture of footwear, in particular sports shoes, the sheet structure according to the invention has exceptional qualities of comfort and ventilation. I1 is added a massage of the foot of the user, thanks to the large number of support points constituted by the separate elements.

Au surplus, dans la réalisation préférée ci-dessus comportant une nappe textile opposée aux éléments séparés, la semelle est réversible, ce qui permet, selon les besoins ou les goûts, par exemple selon les saisons, de donner au pied de l'utilisateur un contact avec les éléments séparés ou, au contraire; avec la nappe textile. In addition, in the above preferred embodiment comprising a textile sheet opposite the separate elements, the sole is reversible, which allows, according to needs or tastes, for example according to the seasons, to give the foot of the user a contact with separate elements or, on the contrary; with the textile tablecloth.

Le mode de réalisation préféré de l'invention est illustré au dessin annexé dont la figure unique est une coupe transversale schématique de la structure en feuille selon l'invention. The preferred embodiment of the invention is illustrated in the accompanying drawing, the single figure of which is a schematic cross section of the sheet structure according to the invention.

Sur la figure, ai a montré en 1 les boucles constituant les éléments séparés. Elles sont formées et agencées comme décrit ci-dessus. Au surplus, elles peuvent avoir une hauteur et/ou une orientation constantes ou, au contraire, variables. Eventuellement, les boucles peuvent être coupées pour constituer des crochets antidérapants. In the figure, ai has shown in 1 the loops constituting the separate elements. They are formed and arranged as described above. In addition, they can have a constant height and / or orientation or, on the contrary, variable. Optionally, the loops can be cut to form non-slip hooks.

Les boucles 1 sont assujetties à leur support 2 qui est souple et aéré. I1 est lui aussi réalisé par tricotage ou par tissage. The loops 1 are subject to their support 2 which is flexible and ventilated. I1 is also made by knitting or weaving.

Quant à la couche intermédiaire 3 de mousse et à la couche externe textile 4, elles sont constituées et agencées comme décrit ci-dessus. As for the intermediate layer 3 of foam and the outer textile layer 4, they are formed and arranged as described above.

Le fond intérieur de la chaussure, dit "première" peut être équipé de moyens antidérapants, du genre crochets ou boucles, coopérant avec l'une des faces de la structure selon l'invention. The inner bottom of the shoe, called "first" can be equipped with non-slip means, of the hook or loop type, cooperating with one of the faces of the structure according to the invention.

A l'usage, l'ensemble des boucles constitue une sorte de matelas élastiquement compressible, tandis que la base, également compressible grace à la mousse, permet, en conjugaison avec les boucles, une bonne circulation de l'air.  In use, all of the loops constitute a sort of elastically compressible mattress, while the base, also compressible thanks to the foam, allows, in conjunction with the loops, good air circulation.
