Abstract

An insole (1) is formed in one piece with a boxed-in toe puff (2) and a raised edge heel counter (3) by injection moulding of plastics material. This is economical and simplifies assembly of the eventual shoe.

Description

[Detailed description of the invention]

The present invention relates to fishskin made to incorporate both toe and heel leather, and is particularly suitable for use in making sports shoes.

[Conventional art]

In order to stiffen the toe of the shoe, various forms as well as formed like a specific flat element attached to the heel, the front toe provide reinforcement during the assembly of the shoe. Fish skin made from this material is well known. This is especially true in the case of sports shoes such as snowflake shoes and mountaineering boots. Because the stiffness of various parts of the shoe is different,
Different materials are used for different parts of the shoe assembly. During assembly, the various parts must be joined together by stitching or adhesive. The seams often protrude from the skin surface, which can be uncomfortable for the person wearing the shoe.

[Purpose of the invention]

It is an object of the present invention to provide an economical integrated fishskin that can be produced using standard equipment in the footwear industry and contains all the necessary parts that simplify the assembly and production of shoes. That is. To this end, the present invention provides a fishskin trap in which a box-in toe and a heel leather with a raised hem are integrally formed by injection molding of plastic snack material. . Preferably also the fish skin, with grooves on the upper side for the seams and grooves on the lower side for covering the whole support strip or a part thereof, in order to obtain different degrees of firmness in each location. formed with varying degrees of thickness.

【Example】

The invention will be further described with reference to the accompanying drawings. With reference to the drawings, the preferred embodiment of the fish skin of the present invention is constructed into a flat element, which resembles the sole of the foot in its construction, the front part of which has an integral box-in toe pad 2. The heel leather 3 is integrally formed in the rear part thereof. The heel leather 3 is formed as a raised edge at the center back of the heel. These three parts, namely the fishskin element 1, the toe 2 and the heel leather 3, are formed in one piece in a conventional manner by injection molding plastic snack material into a suitable mold. On the upper side of the fish skin element 1 there are two holes or grooves 4 adjacent to the side edges. These grooves reduce the thickness of the fishskin and allow it to contain the suture assembly when the remaining portions of the shoe, ie, the upper and sole, are attached to the fishskin. With this method, the seam will be located below the upper surface of the fish skin,
Do not make the person wearing the shoes feel uncomfortable. The toe 2 has a plurality of flexible cuts along its free edge, allowing the toe to conform itself as the shoe flexes during walking. A connecting side edge 6 is provided between the toe 2 and the heel leather 3, and this side edge can be either low or high as shown by the dotted line. The fish skin element 1 has a flexible deformable central region 8;
The region is not as thick as the end region. By suitably selecting the thickness throughout the fish skin, it is possible to vary the degree of deformation, so that some parts can be made more flexible and others stronger and stiffer. On the lower side of the fish skin element 1 there is a longitudinal groove 9 adapted to receive a support strip or leaf spring 10 of the same size as the groove 9, on which the strip 10 is placed. certain hole 11
and are attached by rivets passing through holes 12 in the fish skin. Alternatively, as shown in FIG.
You can also accept 3. The seed strip is held in place by a rivet passing through a hole 15 in it and a corresponding hole 16 in the fish skin l. The strip 14 is formed as a hook 19 which extends rearwardly and projects from the assembled shoe. In use, the fish skin is assembled with the upper part 17 and the sole 18 and attached to the m- by stitching or the like to form the shape of a shoe, as shown in FIG. 5'. ``Fish skin has the desired hardness and has the appropriate deformability desired at each location when the shoe is put on and used. Otsu's fish skin maintains its shape, no matter what happens.
Do not lose the shape of the product itself. This shape is very important. This is because the integral formation of the toe and heel leather simplifies the manufacturing of the shoe. Furthermore,
The aesthetic and functional features of manufacturing are improved. The sutures necessary for attachment of the sole, upper part and insole are accommodated in the grooves 14, so that they do not break or cause discomfort to the foot. The combination of such insole and support strips of different sizes and shapes makes it possible to give the shoe specific features for specific uses. Indeed, the insoles of the invention are particularly suitable for use in the manufacture of sports shoes, such as utility boots and mountaineering boots. It will be understood that the foregoing description is for illustrative purposes only and does not limit the scope of the invention, and that various modifications may be made within the scope of the claims.
