Abstract

The utility model relates to a structure improved shoe pad, which is composed of an EVA foaming layer, an antisepsis PU foaming layer and a cloth surface layer. A plurality of convex floating blocks which are properly arranged are arranged on the surface of the EVA foaming layer. Channels which alternatively extend are formed on the circumference of the convex floating blocks. A plurality of air-permeable holes passing through the EVA foaming layer are arranged in proper positions of the channels and the convex floating blocks. The antisepsis PU foaming layer is integrally covered on and stuck to the top surfaces of the convex floating blocks of the EVA foaming layer. The cloth surface layer is covered on and stuck to the top surface of the antisepsis PU foaming layer. A shoe pad body utilizes the convex floating blocks to enhance the good elasticity of the EVA foaming layer. A flowing channel and space which are required by the ventilating effect of the antisepsis PU foaming layer are provided through interlaced channels and air-permeable holes. Thus, the shoe pad body has the advantages of great enhancement of effects of ventilation, antisepsis, mould prevention and comfort and reduction of production cost.

Description

Improve the insole body of structure

The utility model relates to a kind of insole body that improves structure, it mainly is by the default some protruding floating blocks in ethene-vinyl acetate copolymer EVA foaming layer surface, and conduit is stretched by the company that is staggered to form relatively, offer some air-vents thereon again, cooperate each protruding floating block surface one to fit and cover multiple antibacterial polyurethane rubber PU foaming layer and cloth cover, the composition design of its special construction, can impel insole body thoroughly to reach significantly to improve the effect of ventilative, antibacterial and mouldproof and comfortableness, with the practical purpose that reduces the production and processing cost.

As shown in Figure 1, conventional footwear pad 10 is directly to attach cloth cover 12 in EVA foaming layer 11, because of EVA foaming layer 11 is insulation and air-locked material, so make the shortcoming that has sultry, fustiness etc. in insole body 10 uses; And for example shown in Figure 2, another conventional footwear pad 20 is directly to attach cloth cover 12 up and down in polyurethane rubber PU foaming layer 21, though PU foaming layer 21 has gas permeability, but upper and lower side abuts against respectively under foot and between the sole, there is no suitable ventilation space, so air permeable effect is still poor, still have shortcomings such as use is sultry, fustiness.The support elastic force of PU foaming layer 21 also is not enough to EVA foaming layer 11 in addition, cause insole body 20 that the shortcoming of shock-absorbing comfortableness deficiency is also arranged, no matter which kind of insole body 10,20 by hot pressing machine-shaping, causes the not remarkable and high shortcoming of cost of long processing time, efficient.So, how to develop a kind of insole body structure that ventilative, mildew-resistant and comfortableness have concurrently that has more, be the novel product that the consumer looks forward to, also be target and direction that the relevant industries personnel make great efforts to research and develop.

Main purpose of the present utility model provides a kind of insole body that improves structure, it is to improve at the shortcoming of above-mentioned ventilative effect and comfortableness deficiency, mainly by the default some protruding floating blocks in EVA foaming layer surface, and conduit is stretched by the company that is staggered to form relatively, offer some air-vents thereon again, cooperate each protruding floating block surface one to fit and cover multiple antibiotic PU foaming layer and cloth cover, the composition design of its special construction, can impel insole body thoroughly to reach significantly to improve the effect of ventilative, antibacterial and mouldproof and comfortableness, with the practical purpose that reduces the production and processing cost.
