Abstract

The utility model relates to a shoe insole. The insole is composed of two different materials, and a sealed annular isolating line is arranged at the inner side of the outer ring surface of the insole with a proper distance. PU foaming material is formed into an elastic region inside the range of the isolating line, while EVA foaming material is formed into a lightweight region outside the range of the isolating line, and thereby, the insole can adapt to the requirements of various sporting footwears.

Description

Shoe insole

The utility model is relevant with the end in a kind of footwear.

According to the difference of motion kind, for example movement pattern relaxes jogs and belongs to the basketball, tennis etc. of strenuous exercise, for demand in response to different motion, and end difference to some extent in the footwear of sporter institute wear footwear when motion.Wherein the most basic requirement in the middle end of jogging shoes is the functions that must have light weight, therefore at present the shoemaking dealer is to be the middle end that ethene-vinyl acetate (ethylene-vinyl-acetate) foam material is made jogging shoes with EVA, though the EVA foam material have light weight (about 0.15～0.29 gram/cubic centimetre of proportion), not facile hydrolysis, smooth surface, can not flavescence etc. advantage, but because of elasticity is not good, compression reaction power is poor, so after jogging shoes wear a period of time, the middle end, almost do not had elasticity fully, when wear, running foot done not feel like oneself.

In addition, with regard to footwear such as basketball footwear, tennis shoes because must adapt to violent motion, thus the most basic demand be must good springiness, compression reaction power is good, so generally be to be that polyurethane (polyurethane) foam material is made with PU.Though, the PU foam material has above-mentioned advantage, but its shortcoming but is a quality heavier (proportion 0.3～0.35 gram/cubic centimetre), the footwear that this and strenuous exercise use (as basketball footwear, tennis shoes) need the characteristic of light weight not meet, and the PU foam material is many because of easily hydrolysis, aging, surface flavescence easily, surface pores, and makes its appearance quite not attractive in appearance.

Though the end all respectively has its advantage in the footwear of various kinds, relatively also there is the very important disappearance of work.

In addition, the middle end that above-mentioned two kinds of unlike materials are made is to be used in respectively on the different footwear, and is quite inconvenient in the process of making footwear spare, adds the difference of shoe size, pattern again, can increase the material management costs.

Main purpose of the present utility model is to be to provide the end in a kind of footwear, and the end is to constitute with two kinds of unlike materials in the described footwear, applicable to the demand of various footwear, and the advantage of two kinds of foam materials is brought into play fully.

According to the end in the footwear provided by the utility model, it is characterized in that:

The end, located along its outer ring surface and in slightly in the described footwear, is formed with the isolating line of closed circular, and described isolating line is made of the rubber-like material with interior zone, and the zone beyond the isolating line is made of light-duty foam material.

, described rubber-like material is the PU foam material at the end in footwear of the present utility model, and described light-duty foam material is the EVA foam material.

The end, have the good and light weight of elasticity simultaneously in the footwear of the present utility model, can hydrolysis, smooth surface, can flavescence etc. advantage, be applicable to the footwear spare of various motion kinds.

Below by most preferred embodiment and accompanying drawing the utility model is elaborated, in the accompanying drawing:

Fig. 1 is the schematic perspective view of the utility model preferred embodiment.

Fig. 2 is the above-mentioned preferred embodiment positive combination of a utility model profile.

Fig. 3 is the above-mentioned preferred embodiment of a utility model side combination section.

Fig. 4 is the manufacturing process calcspar of the middle end of the above-mentioned preferred embodiment of the utility model.

Fig. 5 is the another kind of manufacturing process calcspar in the middle end of the above-mentioned preferred embodiment of the utility model.

Please cooperate and consult Fig. 1,2,3, the end 10, is along the inside of the at interval suitable distance of its anchor ring in the utility model footwear, the isolating line 101 that closed circular is arranged, distance between described isolating line 101 and outer ring surface is about 10 millimeters, and described isolating line 101 can form elastic region 11 by the PU foam material with interior scope, then is formed with lightweight district 12 with the EVA foaming beyond the isolating line 10.

By this, when foot is through shoes inside and weight application in described the time at the end 10, the characteristic that the described elastic region 11 of mat work is provided, can obtain advantages such as elasticity is good, compression reaction is good, as for 12 in described lightweight district can provide light weight, can not hydrolysis, smooth surface, can not flavescence etc. preferable outward appearance condition.So, of the present utility model in the end 10 have attractive in appearance, the lightweight district 12 of light weight and the elastic region 11 that elasticity is good, compression reaction power is strong simultaneously, possess light weight, the good jogging shoes of elasticity applicable to need, and the basketball footwear, the tennis shoes that are applicable to strenuous exercise.

In addition, the mode of making at the middle end 10 of the present utility model, can adopt following dual mode:

One. see also shown in Figure 4, after the severing of EVA sheet, carrying out shape grinds, and the PU foam material of moulding is in advance put in the EVA foam material inside that grinds to form reservation shape, integral body is placed in pressurization in the mould, heating, impel the EVA foam material to combine with the PU foam material, just can moulding.

Two. see also shown in Figure 5ly, the EVA raw material with the extruder extrusion molding, put into moulding in advance and PU foam material with reservation shape in the inside of EVA foam material again, with integral body insert pressurization in the mould, heating is promptly plastic.

Claims

1, the end in a kind of footwear, it is characterized in that:

The end, located along its outer ring surface and in slightly in described, is formed with the isolating line of closed circular, and described isolating line is made of the rubber-like material with interior zone, and the zone beyond the isolating line is made of light-duty foam material.

2, the end in the footwear according to claim 1, it is characterized in that wherein said rubber-like material is the PU foam material, and described light-duty foam material is the EVA foam material.
