CN201388603Y - Sole - Google Patents

Abstract

The utility model discloses a sole which consists of soft materials and hard materials and forms a foot shape, wherein the soft materials are added with auxiliary materials at the bottom part and have smaller density; the hard materials have bigger density at the bottom part and on the periphery; and in fact, the sole is of a two-layered structure. Prepared shoes not only have the advantages of high strength and good wear resistant property of the hard materials, but also have the advantage of good bending property of the soft materials.

Description

A kind of sole

Technical field

The utility model relates to a kind of sole that footwear are used.

Background technology

When making sole, often adopt various different materials, as rubber, EVA, PVC etc., but, all make single density sole no matter adopt which kind of material, if select harder material for use, then sole is really up to the mark and cause bending effect bad; Though if select for use comparatively soft material bending property that guarantee has been arranged, but intensity is low excessively, thereby touch sole easily and cause comfort property bad if run into admant or sharp keen article, then need increase sole thickness if the assurance walking is comfortable, thereby cause sole weight to increase, make people overweight rather inconvenient because of sole when walking.

The utility model content

The utility model aims to provide a kind of intensity height, the dual density sole that sole thickness is suitable and security performance is good.

A kind of sole is characterized in that, this sole center is for adding the less macromolecule soft material of density of auxiliary material, and bottom and periphery are the bigger high molecular hard material of the same race of density and are pin shape.

The utility model adopt the bigger hard material of density as the less soft material of sole bottom and periphery, density as sole center, be actually double-layer structure, make the sole make both possess hard material intensity height, advantage that anti-wear performance is good like this, possess soft material good bending property, advantage comfortable and easy to wear again; Thereby cause the different arrangement respective material of wearing and tearing with contacting with ground owing to can do according to the force-bearing situation of sole different parts, compare with single density sole, under service life roughly suitable situation, sole thickness is thinner, thereby reduce sole weight, can alleviate the burden when walking greatly; In material for sole of shoe, add auxiliary material, can play sterilization, can play the effect of deodorization again.

The specific embodiment

Embodiment one

Fig. 1 is a kind of schematic diagram of sole, its structure as shown in Figure 2, form by density different materials of the same race, be injected into bottom and periphery by the bigger hard PU material 3 of employing density successively in corresponding mould, the less soft PU material 4 of density that will add spices after the cleaning again injects the middle part and is processed into pin shape.

Embodiment two

Fig. 1 is a kind of schematic diagram of sole, its structure as shown in Figure 2, form by density different materials of the same race, be injected into bottom and periphery by the bigger hard PVC material 3 of employing density successively in corresponding mould, the less flexible PVC material 4 of density that will add colouring agent after the cleaning again injects the middle part and is processed into pin shape.

Embodiment three

Fig. 1 is a kind of schematic diagram of sole, its structure as shown in Figure 2, form by density different materials of the same race, be injected into bottom and periphery by the bigger hard EVA material 3 of employing density successively in corresponding mould, the less soft EVA material 4 of density that will add spices after the cleaning again injects the middle part and is processed into pin shape.

Claims (3)

1. sole is characterized in that: this sole center is for adding the less macromolecule soft material (4) of density of auxiliary material, and bottom and periphery are for the bigger high molecular hard material of the same race (3) of density and be pin shape.

2. sole according to claim 1 is characterized in that: injection moulding is PU, PVC or EVA with the material of sole.

3. sole according to claim 1 is characterized in that: the auxiliary material that is added is spices or colouring agent.
