Description

High elasticity sole and shoes

Technical Field

The utility model relates to a technical field of shoes, especially a high elasticity sole and shoes.

Background

With the continuous progress of society, various foot protection tools, such as sports shoes, leather shoes and other shoes, can be carried out, and whether the shoes are comfortable to wear is a necessary consideration for people to select the shoes.

Taking a sports shoe as an example, it is well known that the sports shoe is one of shoes that modern people prefer to wear, especially when doing outdoor sports. The existing sports shoes comprise soles, uppers connected with the soles and insoles arranged on the soles, are classified according to the existing sole composition materials and generally comprise the following types, wherein the first type is soles formed by foaming bodies with single-pass; the second one is a sole composed of a foaming body and a book grid sheet-shaped rubber sheet adhered to the bottom of the foaming body; the third is a sole with upper and lower layers formed by the foaming body and the sole body.

The first sole has light weight and good elasticity, and is mainly characterized in that a thicker elastic foaming body is added into the sole. However, the foam is thicker when in use, so that the proportion of the sole is not good, the movement is not facilitated, and the anti-skid effect is poor.

The second sole also has light weight and better elasticity, and has certain anti-skidding effect because the plurality of flaky rubber sheets are arranged, but the plurality of flaky rubber sheets are independently adhered to the foaming body, and the rubber sheets have smaller volume and are easy to partially fall off, thereby affecting the integral attractiveness of the shoe body.

The third sole has better anti-skidding effect, but the whole elasticity of the sole is too poor, and the whole flexibility is not ideal.

In order to overcome the technical problems, the invention provides a high-elasticity sole and a shoe.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects of the present invention to be solved clearer and more obvious, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1 is as follows:

referring to fig. 1 to 3, a high elasticity sole, includes sole body 1, and mounting groove 2 has been seted up to heel one side direction tiptoe one side of sole body 1, and mounting groove 2 is located sole body 1's heel, and does not extend to sole body 1's bow portion and tiptoe, guarantees that sole body 1 is interior can not the cavity, increases sole body 1's stability. The mounting groove 2 is divided into a central area 3 and a surrounding area 4 surrounding the central area 3, and further comprises an EVA layer 5 arranged on the central area 3 and a TPU layer 6 arranged on the surrounding area 4. EVA layer 5 has the high elasticity, and TPU bracing piece 7 has high wearability, and sole body 1 has higher waterproof nature for the bottom simultaneously, and frictional force is great.

The TPU layer 6 is internally provided with a plurality of TPU supporting rods 7, the TPU supporting rods 7 are arranged in the surrounding area 4 in a staggered mode to form hollow parts, and the EVA layer 5 is matched to absorb shock during rebounding. The both ends of every TPU bracing piece 7 are fixed in the up end and the lower terminal surface that encircle district 4 respectively, or the both ends of part TPU bracing piece 7 are fixed in the up end and the lower terminal surface that encircle district 4 respectively, and another part TPU bracing piece 7 one end is fixed in the lower terminal surface that encircles district 4, and the other end is fixed in the lateral wall on the TPU bracing piece 7 body of rod or EVA layer 5. The TPU support rods 7 are arranged at intervals in the surrounding area 4. One end of the surrounding area 4, which is far away from the toe cap of the sole body 1, is a dense area 8, the rest surrounding areas 4 are evacuation areas 9, and the density of TPU (thermoplastic polyurethane) support rods 7 in the dense area 8 is higher than that of TPU support rods 7 in the evacuation areas 9. According to the stress condition of the sole, the density of the TPU support rod 7 is adjusted, so that the bearing capacity is adjusted, the phenomenon that elastic deformation is not easy to occur when the TPU support rod is normally walked is guaranteed, and meanwhile, a higher damping effect is guaranteed and the weight of the sole is reduced.

The EVA layer 5 is mainly made of rubber-plastic foaming material, and the specific components are EVA7470 parts; EPDM3092 parts; 45 parts of BER6000 elastomer; 20 parts of BRH-70 elastomer; 0.6 part of stearic acid; 0.8 part of zinc stearate; 0.8 part of transparent zinc oxide; 0.6 part of MR-02 flow assistant; 1.2 parts of TAIC bridging auxiliary agent; 3 parts of an AC foaming agent; 0.25 part of DCP crosslinking agent; the EVA layer 5 is secured to the central region 3 by adhesive or stitching.

A plurality of anti-skid protrusions 10 are convexly formed on the lower end surface of the sole body 1. The antiskid bulges 10 are all in a broken line shape, protrude from one side of the heel to one side of the toe cap and are arranged at even intervals. By arranging the antiskid projections 10 and forming the antiskid projections 10 into broken lines, the contact area between the antiskid projections 10 and the ground is increased, and therefore friction force is increased.

Example 2 is as follows:

referring to fig. 4, a high elastic footwear comprising the high elastic outsole 11 of example 1 and the upper 12 fixed to the high elastic outsole 11 has all the characteristics of the high elastic outsole 11 of example 1.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
