Shoe sole
Description

The invention relates to a shoe sole made of leather and rubber or plastic.

The invention is based on the task of designing a shoe that is as simple as possible, yet durable and yet high-quality and comfortable.

To solve this problem, it is proposed to design the sole in such a way that it already fulfills the most important tasks of a shoe bottom, but at the same time is made up of fewer components than conventional bottoms. The injection-molded (plastic) or cast (rubber) sole blank (1) already contains a negative foot plastic (footbed) on the top. The sole blank has a surrounding sole frame (7) that was molded onto the shaft edge using a seam (5). On the underside of the sole blank is a flat surface onto which a profiled outsole (2) is mounted.

The invention is described in more detail by way of example with reference to the drawings.

Show it:

Fig. 2 Side view sole

Fig. 4 View of the sole in the ball area

Fig. 5 Side view of one-piece molded sole

Fig. 1 shows a top view of the tread (2) of the sole (1) with the molded frame (7). The seam (5) runs all the way around and connects the shaft edge (6) with the leather insole (3) and the sole blank (1).

The sole edge (8) is offset from the outsole surface (2) to the outside at the same distance of approx. 10 mm. The sole frame (7) also runs parallel to the upper edge of the sole blank (1) all the way around with a thickness of approx. 6 mm.

The sole (1) can be connected directly to the shaft (6) after the leather insole (3) and the outsole (2) have been glued on. To do this, the sole is attached to the last and the shaft is lasted over it. When lasted, the shaft edge (9) is folded outwards, as can be seen in Fig. 4, and fixed to the sole frame using glue or another suitable connection. The shaft edge (9) and the sole blank (1) with the already mounted leather insole (3) are doubled in a further step, i.e. sewn together all the way around (5). The outsole (2) can also be glued on after doubling (sewing).

Based on this basic model, further designs are conceivable:

One-piece molded sole , Fig. 5, here the entire sole is injected (plastic) or cast (rubber) from one material. The outsole is already molded in this version. A leather insole can be glued on before sewing it to the shaft.

Multi-layer injected molded sole . When manufacturing the molded sole, plastics of different hardness can be used, injected in layers on top of each other. The outsole layer can be made of hard, abrasion-resistant plastic, for example, while the top layer is made of soft, cushioning material.

Multi-layered sole , the sole blank can also be made up of several plastic or rubber plates that are assembled layer by layer. The foot plastic can then be milled in.

Claims (6)

1. Shoe bottom, characterized in that the foot plastic ( 4 ) and outsole as well as a surrounding sole frame ( 7 ) for making a seam connection between the sole ( 1 ) and the shaft ( 6 ) are already molded. ( Fig. 5) 2. Shoe bottom according to claim 1, wherein a leather insole ( 3 ) is mounted and the underside of the sole blank forms a flat surface onto which a profiled outsole ( 2 ) is mounted. 3. Shoe bottom according to claim 1 and 2, wherein plastics of different strength and hardness levels are used for the production of a bottom. 4. Shoe bottom according to claim 2, wherein sheet materials are used for production. 5. Shoe bottom according to claim 1 and 2, wherein rigid material such as wood or metal is used. 6. Shoe bottom according to claim 2, wherein the shaft ( 6 ) can be made of one or two layers of leather, of textile fabric, or of synthetic materials.
