First, the production of the textile element 2 which can be used in the manufacture of articles of footwear according to the invention is described.

This embodiment is schematically shown in Figs. 1A and 1B.

It includes a first portion forming a sock foot 10 provided with an end 12 and a heel 14. [ This foot is extended by the upper (16). These elements 10, 12, 14, 16 constitute a typical structure of the sock. However, in the sock used here, the upper 16 extends by the second heel 18 and is then extended by the second upper 20 with the end opening 22. [ This element has a substantially U-shape when arranged on a planar surface, as in Fig.

An opening 21 may be provided in the second upper 20 to allow passage of a cord forming a cord.

The assembly is substantially symmetrical with respect to plane C-C ', the trace of which is shown in FIG. 1B and is substantially orthogonal to the axis of the upper 16. The symmetry does not involve the end 12 and the opening 22.

The steps of a method for manufacturing an element such as that described above with reference to Figures 1A and 1B are described with reference to Figures 2A-2C.

A substantially cylindrical textile element 1 having a diameter substantially corresponding to the diameter of the upper 16 is fabricated on the cylinder 5 by, for example, knitting, weaving or braiding (Fig.

When finished, the element 1 is removed from the support 5 and two notches or cutouts 4, 8 are made on the side that positions the heels 14, 18 thereon (FIG. 2b). Figure 2b already shows an opening 22 to terminate the element 10.

The cutouts 4, 8 allow the ends of the textile element 1 to be spaced apart from the axis of symmetry X, X 'of the cylinder.

The textile portions 14, 18 forming the heel and the portion 12 forming the end of the foot of the sock can then be secured to the openings made from the notches 4, 8 (Fig. 2C). This makes it possible to obtain an element of the type described above with reference to Figures 1a and 1b.

The textile used in the element 2 and the above-described method may be uniform over the entire sock. The textiles may have one or more specific physical and / or chemical properties to incorporate a given function. For example, it may have a composition and / or means for performing one or more of the following functions: odor control, fungus control, water absorption, skin healing, impervious or water repellent (impermeable to some extent Resistance to intrusion of these objects, abrasion resistance, and resilience.

Also, one or more of these properties can only affect one or more local portions of the sock. For example, one portion may have characteristics that allow it to resist intrusion of these objects, which may not be necessary for other portions. As another example, one portion may be impermeable, which may not be necessary for another portion.

Thus, the element 2 and the textile used in the method may be uniform, have specific local, physical and / or chemical properties to incorporate one or more of the above functions.

Hereinafter, various embodiments of the reinforcing structure 3 that can be used in the manufacture of the article of footwear or shoes according to the present invention will be described with reference to FIGS. 3A to 3E.

Each of these various examples is made of a fiber-based material, such as polyamide, polyurethane, or any equivalent material, and is configured to form a portion of the boot assembly and the side reinforcement means. In a non-limiting manner, the structure 3 may be obtained by molding a thermoplastic elastomeric material, or may be obtained by any technique known to those skilled in the art.

3a shows a first example of such a reinforcement element 3 which comprises a flexible portion 3 forming a sole 30 delimited by edges 30 ', 30 " And the side reinforcement elements 31-36, the first end of the side reinforcement element being attached to one of the edges 30 ', 30 "of the sole 30, while the other end is shown in Figure 3C As well as means 31a-36a for forming a keeper for the passage of one or more straps or cords 37, which are configured to form one or more shims, for example of the type terminated by a tightening element 39 It is possible. Each of the side reinforcement elements preferably has a shape as shown in Figure 3a extending far from an end opposite the corresponding edge 30, 30 'of the sole 30 to an end directly connected to the edge of the sole. This shape makes it possible to have more efficient reinforcement in the side zones.

Due to its shape of the thin fibrous layer, the sole 30 is preferably flexible along two directions, one of which is orthogonal to the axis of the foot and the other of which follows the same axis. This results in improved coordination in terms of subsequent steps.

In the embodiment of Fig. 3A, the sole 30 is planar, and is not limited to its forward portion nor its rear portion. Thus, the sole does not define the boundaries of the zone where the foot ends, nor does it specify the boundaries of any zones forming the stiffener for the foot.

The embodiment shown in FIG. 3B includes all of the elements described above with reference to FIG. 3A (and therefore these elements will not be described again), but the elements 40 forming the toccap and delimiting the type position of the forefoot And further includes a front end portion of the sole. Using the previous embodiment, this reinforcement element has no restrictions on the rear zone of the foot, and in particular has no element that defines a stiffener. The front element 40 is also made up of a band made of a fiber-based material and arranged substantially orthogonal to the plane defined by the sole.

The embodiment of FIG. 3C includes a side fiber file 43, 43 ', which provides a predetermined strength or rigidity to the rear portion while retaining certain flexibility, as well as a zone 40 for delineating the type position of the forefoot. And a rear zone 42 connected to at least a portion of the stiffening elements 31-36 and forming a stiffener. The other elements shown in FIG. 3C are the same as or similar to those already described above with reference to FIGS. 3A and 3B.

The embodiment of Fig. 3D is a modification of Fig. 3C. The structure including the side reinforcement means, the toe cap 40, and the rear stiffener 42 is still achieved, but this time it has two parts by combining the structure of Fig. 3a and the structure of Fig. 3e. The structure shown in Figure 3e also includes reinforcing means in the form of a sole forming portion 30a, a toe cap 40, a rear portion 42 forming a stiffener, and side fiber piles 43a and 43a ' Side element. 3A can be inserted at this portion, for example until the front edge of the sole 30 is in contact with the inside surface of the toe cap 40. [ Disassembly is also possible wherein the reverse assembly is such that the structure of Figure 3e is attached to the structure of Figure 3a with the upper portions of the reinforcing elements 31-34 being joined to the edges 430, 430 'of side fiber files 43a, 43a' , Respectively, until it substantially coincides with the respective portions of the first, second,

Hereinafter, a method of manufacturing shoes from the various elements already described above will be described.

To this end, a foam or preform is used, such as a solid form 50 shown in front and side in Figures 4a and 4b, respectively. This form assumes the outline of the foot.

The textile element of FIGS. 1A and 1B can be fitted on the foam to obtain the intermediate element shown in FIGS. 5A and 5B. The front end portion 12 of the sock is brought into contact with the front foot and the portion 10 covers the foot itself and the portion 14 comes into contact with the heel and the upper portion 16 surrounds the ankle, (18) is in contact with the rear upper part thereof. The assembly is extended by a second upper 20.

One of the reinforcing elements of Figures 3A-3E is located on this assembly: here the composite element of Figure 3D is selected. The forward portion of the foot of the foam 50 (socked) is positioned relative to the inner surface of the toe cap 40 and the stiffener 48 is positioned against the rear of the heel of the foam 50. In terms of the flexibility of the fibrous material that is a component of the reinforcing element thus positioned, the reinforcing element can be adjusted to the shape defined by the solid element 50. In addition, the structure of the reinforcement means of Fig. 3 has the advantage that the two parts, front and rear, possibly slide against each other, allowing the reinforcement structure to be adjusted to the dimensions defined by the foam 50 .

As seen in Figures 6a and 6b, the opening 21 made in the second upper 20 of the sock allows passage of the cord (s) which will subsequently enable closing the shoe.

These two elements, the sock made of a textile material and the reinforcing element, can be assembled by, for example, gluing, whereby the assembly forms an irreversible structure. Alternatively, the assembly may be treated with a heating step to achieve fusion of the material of the reinforcing structure and the material of the sock 10.

In an alternative embodiment, the sock and reinforcement element made of textile material can be reversibly assembled. For example, the surface on which each assembly, are connected by an, snaps (snap-fastener), buttons, and a "Velcro ^®" means a hook-and-loop surfaces, such as of the type arranged in a zone adapted to be brought into contact with each other.

During the subsequent steps, as shown in Figs. 7A and 7B, the portion forming the second upper 20 may then be pulled over the foot, and this step requires only a malfunction by the operator. The operator grasps the edge of the end opening 22 of the sock and gradually pulls on the upper part of the foot and the part forming the second upper 20 on both of the zones forming the sole.

The operator continues this operation until the opening 22 touches the front end of the sock and forms an assembly as shown in Fig. 7C. The second heel 18 then covers the first heel 14 located in the first textile layer in contact with the foam 50. The cord 37 and its tightening means 39 are accessible through the opening 21. [

It is also possible to reinforce the resulting assembly by inserting a further reinforcing layer, i. E. By inserting the structure of figure 7c into a second reinforcing structure from one of the types already mentioned above with reference to Figures 3a-3e.

The article of footwear is thus achieved and the article of this footwear may possibly be completed by, for example, gluing the sole 52, which is stronger than the fibrous material portion 30 of the reinforcing element (see Figure 8) ).

The assembly obtained with or without the sole 52 is very light since it contains only two textile layers and at least one reinforcing element made of a very fine and very light fiber material. Thus, the structure includes two "skins " in which one or more reinforcement elements are arranged between the skins.

As will be understood by reading the description, the task does not implement any stitch steps, or any difficult steps to locate the element with respect to each other. Thus, it is possible to achieve the article or footwear of footwear in a very simple, very fast, and very economical way.

The exemplary embodiment given above implements a sock of the kind described with reference to Figs. 1A and 1B, i.e. a sock having two uppers 16,20.

In another example of the embodiment shown in Figures 9A and 9B, a simple sock with a single upper 16 is used. This sock is fitted on the foam 50 of Figs. 4A and 4B. Next, as in the steps of Figs. 6A and 6B, a reinforcing structure, for example one of the types described above with reference to Figs. 3A-3E, is applied to the assembly. The textile element and the reinforcing element (s) after (e. G. Adhesion and / or by heating) to the assembly or permanently, or the snaps arranged in a zone adapted to be brought into contact with each other, a button, and the "Velcro ^®" type of hook And is assembled reversibly by such means as an < RTI ID = 0.0 > loop < / RTI >

This results in the structure of Fig. 9b, which may be completed by the sole 52, as shown in Fig.

In this other example of embodiment, a material having one or more physical and / or chemical properties may also be used as the textile material of the sock to provide one of the functions already mentioned above. In addition, these properties or characteristics may be homogeneous throughout the textile material, or localized only to a portion of the textile material.

It has been shown that the textile element 2 can be made in one piece in that the first part and the second part are produced directly contiguous to each other. However, as an alternative, the textile element 2 may comprise two or more parts affixed to each other by any suitable means such as stitches.
