Abstract

The utility model relates to a shoe-pad, composed of a fabric layer attached by an elastic bottom layer, and is characterized in that the elastic bottom layer is provided with a plurality of air holes of predetermined shape arranged densely to have the effect of overall ventilation, the outer surface of the elastic bottom layer is provided with a layer of film to enhance the structural strength, and an attached surface is provided with a plurality of pores for gluing and attaching.

Description

Shoe-pad

The utility model is relevant with shoe-pad, particularly relates to a kind of shoe-pad of tool air permeable effect.

Just known in the art, sport shoe-pad mainly can be divided into the ventilative cellular type of nothing and ventilative cellular type two classes are arranged with regard to its structure.

There is not ventilative cellular type shoe-pad owing to be not provided with air-vent, therefore its footwear material must be selected tool poromeric material such as PU etc. for use, and can't use air impermeability footwear material, as EVA etc., otherwise the airtight easy perspiration of sole and form defect such as pin is smelly, athlete's foot is so its footwear material that can use is severely limited.

But two kinds of the rough segmentations again of ventilative cellular type shoe-pad are arranged: a kind of is the tool gasbag-type, can produce the effect of inlet and outlet during use, as No. 7228980 " automatic air condition shoe-pad " of Taiwan patent, No. 7329813 " ventilating shoepad automatically " and No. 74206681 " cyclical breathing shoe-pad automatically ", yet, the shortcoming of these shoe-pads is complex structures, its manufacturing cost height is difficult for promoting; Another kind is a tool pore formula, by establishing a plurality of holes at the bottom of shoe-pad to obtain ventilative effect, typical person such as Taiwan patent No. 7220663 " tailor's cushion formula shoe-pad " and No. 7320104 " Ventilated shoe-pad " and No. 7324581 " permeability type shoe-pad " etc.

Be penetrated with many pin holes in No. the 7220663rd, the above-mentioned patent on the shoe-pad reaching air permeable effect, but pin hole itself is very tiny, and shoe-pad can the pressurized attenuation when using, and causes its pin hole to be plugged and its gas permeability that detracts; In No. the 7320104th, the above-mentioned patent at the curved arc shape medial surface of tool plasticity and flexible curved surface bottom coated with tissue layer, borrow the distortion of its bottom to reach soft comfortable and ventilated effect during use, but its shortcoming is to wear face is wavy, the sense of touch of long-term dress is not good, and be not suitable for doing sport shoe-pad, and it makes comparatively trouble; Attach the plastic cement stratum reticulare in No. the 7324581st, the above-mentioned patent in the cotton-spinning layer bottom surface, produce the gas permeability effect by the braiding space of plastic net, but its shortcoming is that shock absorption is relatively poor.

Main purpose of the present utility model is to overcome above-mentioned shortcoming, and a kind of shoe-pad with good air permeable effect and applicable various foaming elastic materials is provided.

For achieving the above object, constituted by the cloth layer elasticity bottom of fitting, be it is characterized in that the elasticity bottom is provided with a plurality of gathering and is the air-vents of reservation shape, to obtain the effect of breathing freely comprehensively according to shoe-pad provided by the utility model; Its outer surface has one deck skin membrane, to strengthen its structural strength; Its binding face has a plurality of pores, is beneficial to stick and adheres to.

Now lift after a preferred embodiment and conjunction with figs. be described in more detail in the utility model, wherein:

Fig. 1 is the outside drawing of the utility model one preferred embodiment.

Fig. 2 is the amplification view along 2-2 line among Fig. 1.

See also each accompanying drawing, the utility model is injected or is extruded by expanded material, or be molded into the elasticity ground 11 of tool predetermined thickness, this elasticity ground 11 is integrally formed densely covered frustoconical shrinkage pool 12 when foaming, because this elasticity ground 11 is one step foaming moulding, therefore its surface can form one deck skin membrane 13, the one side of this elasticity ground 11 is eliminated predetermined thickness, its each shrinkage pool 12 1 ends are completely eliminated because of the film that material infiltration mould junction may form, to guarantee that each shrinkage pool 12 all runs through, and form a binding face 14 with pore eliminating on the face of elasticity ground 11, be beneficial to the stick coating, the cloth layer 15 of fitting thereon again, shape that at last will this composite material moulded one-tenth shoe-pad is clipped unnecessary sapwood.

The utility model has the advantage of:

1. elasticity ground 11 is one-body molded to foam, therefore its extexine can form one deck skin membrane 13, this skin membrane extends to the internal face of each air-vent 12, form the supporting walls of shoe-pad air-vent 12, because the hardness transitivity of skin membrane 13 is good than the internal material of foam material all, so the structural strength of shoe-pad air-vent 12 is inevitable strong with elasticity ground punching Durchgangshohle person more merely, therefore its compressive deformation deformation rate Durchgangshohle person that also must punch more merely is little when wearing; And existing do the ground of ground with expanded material, fit again layer of cloth and compression molding, so the skin membrane of expanded material mostly thrown aside, very be unfortunately, the utility model then is cleverly will the useless skin of script Rete makes it form the clad that coats whole sole, and forms supporting walls in order to strengthen the intensity of whole shoe-pad, in order to keep good gas permeability and shock-absorbing effect at the inner face of each air-vent.

2. air-vent can gather to whole shoe-pad in the utility model, its air permeable effect excellence.

3. simple structure of the present utility model, easy to manufacture, and can various foam material manufacturings.

Claims

1, a kind of shoe-pad, it is made of the cloth matter top layer elasticity bottom of fitting, and it is characterized in that: the elasticity bottom is provided with a plurality of gathering and is the air-vents of reservation shape, and its outer surface has one deck skin membrane, and its binding face has a plurality of pores.

2,, it is characterized in that described air-vent shape is tapered according to the described shoe-pad of claim 1.
