Abstract

A first polymer (a) is moulded to form the sole and heel of a shoe, e.g. a shoe for women. Moulding (a) has a recess extending along its top surface; and the depth of the recess is increased in the heel. The recess in the sole part of moulding (a) is used to locate the base of a second moulding (b) made of another polymer; and moulding (b) forms the upper, esp. the tubular upper of a slip-on, toeless shoe. Polymer (a) is pref. more rigid, and more resistant to wear than polymer (b); and the two materials (a,b) pref. have different colours. The overall result is the simple and inexpensive mfr. of a casual, comfortable shoe or sandal.

Description

L'invention concerne un article chaussant. The invention relates to an article of footwear.

L'article chaussant de l'inv-ention est caractérisé-en ce qu'il se compose d'une semelle moulée à l'aide d'une première matière plastique et présentant une zone évide au.nins sur une partie de sa face supérieure et d'une tige, réalisée à l'aide d'une deuxième matière plastique,surmoulée .sur.la,première, ce surmoulage étant tel que la seconde matière plastique comble la zone évidée et constitue ainsi la tige et au moins une partie de la face supérieure de la semelle. The article of footwear of the inv-ention is characterized in that it consists of a sole molded using a first plastic material and having a hollow zone au.nins on part of its upper face and of a rod, produced using a second plastic material, overmolded on the first, this overmolding being such that the second plastic material fills the hollowed out area and thus constitutes the rod and at least part of the upper face of the sole.

Suivant une autre caractéristique de l'invention, la seconde matière plastique surmoulée est une matière plastique plus souple que la première. According to another characteristic of the invention, the second overmolded plastic material is a softer plastic than the first.

Suivant une autre caractéristique de l'invention, la première matière plastique est plus rigide et plus résistante à l'usure que la seconde. According to another characteristic of the invention, the first plastic material is more rigid and more resistant to wear than the second.

Suivant une autre caractéristique de l'invention, l'évidement occupe la quasi totalité de la face supérieure de la semelle et est délimité, à la périphérie de la semelle, par une bordure réalisée par la première matière plastique. According to another characteristic of the invention, the recess occupies almost all of the upper face of the sole and is delimited, at the periphery of the sole, by an edge produced by the first plastic material.

L'invention est représentée, à titre d'exemple non limitatif, sur les dessins ci-joints, dans lesquels
- la figure 1 est une vue latérale d'un article chaussant conforme à l'invention,
- la figure 2 est une coupe suivant A-A de 1 figure 1
La présente invention a en conséquence pour but la réalisation simple.et rapide et donc à faible prix de revient d'un article chaus.sant confortable dont la tige est assemblée de manière robus,te.d la semelle.The invention is shown, by way of non-limiting example, in the accompanying drawings, in which
FIG. 1 is a side view of an article of footwear according to the invention,
- Figure 2 is a section along AA of 1 Figure 1
The present invention therefore aims to achieve simple.et fast and therefore low cost of an article chaus.sant comfortable whose rod is assembled robus, te.d the sole.

Cet article chaussant se compose d'une semelle 1, obtenue par moulage d'une première matière plastique, dont la fac supérieure 2, destinée à supporter le pied, est pourvue d'une zone évidée 3 dans laquelle est surmoulée, en 4, une seconde matière plastique, ce surmoulage étant tel que cette seconde matière plastique forme simultanément la tige 5 de l'article chaussant. This article of footwear consists of a sole 1, obtained by molding a first plastic material, the upper fac 2 of which, intended to support the foot, is provided with a hollow area 3 in which is molded, in 4, a second plastic material, this overmolding being such that this second plastic material simultaneously forms the upper 5 of the footwear.

Cette disposition permettra d'obtenir l'assemblage robuste de la tige 5 et de la partie d'usure 1 de la semelle compte tenu de la grande surface de contact des parties 4 et 1, du procédé d'assemblage par surmoulage et de la jonction continue et directement mise en forme entre la tige 5 et la partie 4, cette jonction pouvant présenter une épaisseur décroissante vers la tige 5 afin d'éviter, de manière plus sure, toute déchirure à la base de la tige. This arrangement will make it possible to obtain the robust assembly of the upper 5 and the wear part 1 of the sole, taking into account the large contact surface of the parts 4 and 1, the assembly process by overmolding and the junction. continuous and directly shaped between the rod 5 and the part 4, this junction may have a decreasing thickness towards the rod 5 in order to avoid, in a safer manner, any tearing at the base of the rod.

Dans l'exemple représenté sur la figure 1, la zone évidée 3 occupe la quasi totalité de la face supérieure 2 de la semelle et est limitée, à la périphérie de cette semelle, par une bordure 1 1 réalisée par la première matière plastique. In the example shown in Figure 1, the recessed area 3 occupies almost all of the upper face 2 of the sole and is limited, at the periphery of this sole, by an edge 1 1 made of the first plastic material.

La première matière plastique moulée est constituée par une matière plus rigide et résistant mieux à l'usure que la seconde alors que cette seconde matière plastique constituant la tige 5 et le remplissage en 4 de la partie supérieure de la semelle est constituée par une matière plus souple que la première. The first molded plastic material is made of a more rigid and wear-resistant material better than the second while this second plastic material constituting the upper 5 and the filling in 4 of the upper part of the sole is made of a more flexible than the first.

Cette combinaison des matières, liée à la structure de l'article chaussant, permet d'obtenir une tige souple pour éviter de blesser le pied, une face supérieure 2 de la semelle qui est souple lors de la marche afin d'améliorer le confort et une partie externe 1 de la semelle résistant efficacement à l'usure. This combination of materials, linked to the structure of the footwear, makes it possible to obtain a flexible upper to avoid injuring the foot, an upper face 2 of the sole which is flexible during walking in order to improve comfort and an outer part 1 of the sole effectively resistant to wear.

De préférence, la zone évidée 3 présente une profondeur plus importante en 31 à hauteur du talon 12 afin d'améliorer encore la souplesse de l'article chaussant. Preferably, the hollowed out area 3 has a greater depth at 31 at the height of the heel 12 in order to further improve the flexibility of the footwear.

D'une manière générale, la profondeur de l'évidement 3 recevant en 4 la partie complémentaire de la semelle sera plus épaisse que l'épaisseur de paroi de la tige 5. In general, the depth of the recess 3 receiving at 4 the complementary part of the sole will be thicker than the wall thickness of the rod 5.

Les deux matières plastiques mises en oeuvre pour la confection de cet article chaussant seront avantageusement de couleurs différentes pour des raisons esthétiques et, dans le cas de l'exemple représenté, pour donner l'apparence d'une première de montage sur la face supérieure 2 de la semelle, cette première de montage étant délimitée par la bordure 1 1 de couleur différente de la première matière plastique. The two plastic materials used for the manufacture of this footwear will advantageously be of different colors for aesthetic reasons and, in the case of the example shown, to give the appearance of a first assembly on the upper face 2 of the sole, this first mounting being delimited by the edge 11 of a different color from the first plastic material.

Le fond de la zone évidée 3, réalisée par la première matière plastique 1, pourra par ailleurs comporter des nervures ou rainures et, d'une manière générale, des anfractuosités susceptibles d'améliorer encore la liaison entre les deux matières plastiques.  The bottom of the hollowed-out area 3, produced by the first plastic material 1, may moreover include ribs or grooves and, in general, crevices capable of further improving the connection between the two plastic materials.
