Abstract

The invention discloses an insole which comprises a sole-shaped shell fabric (1) and is characterized in that a polyurethane auxiliary bedding layer (3) with a pure polyurethane surface without a film is arranged on the lower bottom surface of the shell fabric (11), and a polyurethane soft bedding layer (2) with the pure polyurethane surface without the film is arranged convexly on the lower surface of the auxiliary bedding layer (3) at the position on which a heel and a sole exert forces. Compared with the prior art, the insole has the advantages that people feel that the insole is soft and comfortable when stepping on the insole, and the insole can stick to the bottom surface of a shoe steadily, thereby solving the problem that the insole slips with the change of the force-exerting points of the sole; besides, the insole has simple structure, convenient production and low cost.

Description

Shoe-pad

Technical field

The present invention relates to the shoe-pad manufacture technology field, especially refer to a kind of polyurethane insole.

Background technology

The Chinese utility model patent that existing a kind of patent No. is CN03256541.0 has proposed a kind of structure, it is characterized in that of its structure: described shoe-pad is made up of cloth cover, the pre-type soft thing of high temperature resistant coated fluid and PU foaming material at least, be preset with on the cloth cover and engrave the hole, the pre-soft thing of the high temperature resistant coated fluid of type is hung on the default hole of engraving of cloth cover and locates, and the cloth cover below that is linked with the soft thing of the high temperature resistant coated fluid of pre-type is provided with PU foaming material integrated with it.The shortcoming of this shoe-pad is that structure is complicated, makes trouble, and it is many to make material, and cost is higher; Also have, after this shoe-pad places on the sole face when the people is stepping on shoe-pad and is walking because sole impetus conversion and shoe-pad is slided, cause very inconvenient, also uncomfortable on foot, the improvement so its structure awaits.

Summary of the invention

Technical problem to be solved by this invention be provide at above-mentioned prior art present situation a kind of simple in structure, easy to make, trample soft and can prevent the shoe-pad that slides when shoe-pad uses.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this shoe-pad, include the face cloth of sole-shaped, it is characterized in that: described its bottom surface of cloth is provided with the auxilliary bed course of polyurethane of the pure polyurethane face of the no film in surface, and on the lower surface of auxilliary bed course and the portion of the putting forth effort position that is positioned at heel and sole convex with the flexible polyurethane bed course of the pure polyurethane face of surperficial no film.

As improvement, on described its lower surface of auxilliary bed course and be positioned at position, pin bridge chamber and also can convex with protection pin bridge and fuse with the heel cushion course and the polyurethane pin bridge cushion course of the no film in surface.

Improve, the locational sole flexible polyurethane of described sole bed course adopts fenestral fabric, has both had anti-pad effect, can save cost again again.

Improve, described auxilliary bed course and cushion course are preferably the overall structure by disposable injection moulding formula of mould and face cloth be combined into again, thereby make production convenient.

Improve, it is positioned at described cloth sole and puts with the pin bridge location and be distributed with the passage of being convenient to ventilate that top and bottom communicate, so that can be the Gas scavenging in the footwear chamber better again.

Compared with prior art, the present invention adopts the bottom surface of face cloth to be provided with the auxilliary bed course of polyurethane of the pure polyurethane face of the no film in surface, and on the lower surface of auxilliary bed course and the portion of the putting forth effort position that is positioned at heel and sole convex with the flexible polyurethane bed course of the pure polyurethane face of surperficial no film.The advantage of this structure is: on the one hand, when the people step down on the shoe-pad can vibrationproof and soft feel comfortable, on the other hand, because all having film, the polyurethane surface of auxilliary bed course and cushion course do not coat, so have certain viscosity, when the shoe-pad pad places on the sole, shoe-pad just can stably be pasted together with the sole face, thereby eliminated the problem that owing to the conversion of sole impetus shoe-pad is slided when the people walks, on the one hand, this Shoe-pad structure is very simple again, and promptly positive is that face cloth reverse side is a layer of polyurethane, not only easy to make, and cost is also low.So be a kind of very practical product, usefulness is worthy to be popularized.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Extremely shown in Figure 6 as Fig. 1, the shoe-pad of present embodiment, include the face cloth 1 of sole-shaped, the bottom surface of face cloth 11 is provided with the auxilliary bed course 3 of polyurethane of the pure polyurethane face of the no film in surface, and on the lower surface of auxilliary bed course 3 and the portion of the putting forth effort position that is positioned at heel and sole convex with the flexible polyurethane bed course 2 of the pure polyurethane face of surperficial no film.The surface of auxilliary bed course 3 and cushion course 2 does not all have film and coats, so have certain viscosity, can be pasted together with sole.And on the lower surface of auxilliary bed course 3 and be positioned at pin bridge chamber position male and be provided with and fuse with heel cushion course 23 and the polyurethane pin bridge cushion course 22 of the no film in surface, so that can protect the pin bridge better.Being designed to periphery at the locational sole flexible polyurethane of sole bed course 21 is all circular arc of part, and inside is fenestral fabric, can play anti-pad effect, can save material again.And be that the auxilliary bed course 3 of material and cushion course 2 are the overall structure by disposable injection moulding formula of mould and face cloth be combined into by polyurethane, make very conveniently, put with the pin bridge location and be distributed with the passage of being convenient to ventilate 11 that top and bottom communicate at the sole that is positioned at of face cloth 1.
