CN201563722U - Middle sole - Google Patents

Abstract

A middle sole comprises a half sole and a heel and is made of two different materials, namely EVA foam material and high elasticity material. The high elasticity material is produced through injection and foaming of common EVA recycling material. Since the heel of the middle sole is under the largest stress, a closed annular partition line is formed at the heel. The zone within the partition line is made of soft material with high elasticity, and the zone beyond the partition line is made of EVA foaming material.

Description

The end in a kind of footwear

Technical field

The utility model relates to a kind of footwear parts of articles for daily use to the body-care field, is specifically related to a kind ofly reach comfortable and easy to wear by inserting soft resilient material, the footwear that possess pooling feature with in the end.

Background technology

Mostly the end was to adopt paper board material hard, stereotyped to be made during present existing footwear were used, and its shortcoming is that flexibility is poor, adopted the shoes dress that the end makes in this kind uncomfortable.

Summary of the invention

The purpose of this utility model provides a kind of high resiliency material of inserting on the middle end, it is soft, comfortable and possess pooling feature to reach dress.

The technical solution of the utility model is: design the end in a kind of footwear, comprise half sole and heel, the end, mainly constitute with two kinds of unlike materials in these footwear, be that EVA foam material and high resiliency material are formed, described high resiliency material is to be made through behind the foam-injection by common EVA reclaimed materials, because the heaviest stressed position, the middle end is a heel, promptly be formed with the isolating line of closed circular at described heel place, described isolating line is that material by the high resiliency material of softness is constituted with interior zone, and the zone beyond the isolating line is made of the EVA foam material;

EVA is an ethene-vinyl acetate, with the EVA foam material, have light weight, not facile hydrolysis, smooth surface, can not flavescence advantage; The high resiliency material be by the EVA reclaimed materials through making behind the foam-injection, have good springiness, advantage that compression reaction power is high;

Technique effect of the present utility model is: adopt such scheme can realize the utilization of a kind of EVA material repetitive cycling, and the end in the footwear usefulness that possesses pooling feature that makes, at the bottom of the high-grade sport footwear of special suitable for making, be present a kind of new material, new product, new ideas and can be with the trendy product of closed matereial cycle.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model schematic diagram;

The specific embodiment

As Fig. 1, the end in a kind of footwear, comprise half sole 1 and heel 2, the end, mainly constitute with two kinds of unlike materials in these footwear, be that EVA foam material and high resiliency material are formed, described high resiliency material is to be made through behind the foam-injection by common EVA reclaimed materials, because the heaviest stressed position, the middle end is a heel 2, promptly be formed with the isolating line 21 of closed circular at described heel 2 places, described isolating line 21 is that material by the high resiliency material of softness is constituted with interior zone, and the zone beyond the isolating line 21 is made of the EVA foam material, when the people puts on the footwear made of the utility model when walking, utilize the good high resiliency material of elasticity to slow down the concussion of people's health when walking, play the effect of buffering.

Claims (1)

1. the end in the footwear, comprise half sole and heel, the end, mainly constitute with two kinds of unlike materials in it is characterized in that, be that EVA foam material and high resiliency material are formed, described high resiliency material is to be made through behind the foam-injection by common EVA reclaimed materials, the end, be formed with the isolating line of closed circular in footwear, and described isolating line is that material by the high resiliency material of softness is constituted with interior zone, and the zone beyond the isolating line is made of the EVA foam material.
