Abstract

Provided is a permeable and dry insole comprising a face layer and a foam plastic core layer. The peripheral thereof adopts the stitching or the adhesion treatment. At least one port is left as the air inlet port in the direction corresponding to heel rear part. The parts on the insole corresponding to the middle suspended part of the foot and the toe stepping part also adopt the stitching or the adhesion treatment. The utility model can keep the inner part of the shoe always dry and comfortable. The manufacture process of the utility model is simple and convenient. With only one set of tool equipment and die, mechanical mass production can be realized with an extremely high efficiency, a low cost and a relatively obvious economic benefit.

Description

The dry and comfortable shoe-pad of a kind of exhaust

The utility model relates to a kind of inner sock thing, specifically means the dry and comfortable shoe-pad of a kind of exhaust.

In daily life, often can not in time discharge the people is not felt well, can bring out illness such as beriberi sometimes even also owing to pin sweat in the footwear.So people have developed various different structures, difformity, the footwear that are beneficial to the ventilation perspire and shoe-pad.It is no doubt good that some have the footwear of vented exhaust function, but substitute and can't resolve the perspire problem of the common footwear that quantitatively have overwhelming superiority.So from the shoe-pad a kind of selection that more gears to actual circumstances of can yet be regarded as that finds new outlets.

Chinese patent successively discloses many innovation and creation that relate to the shoe-pad content.Wherein as: CN 2065416U, CN 2114987U, CN 2114986U, CN 2132410Y, CN1082853A, CN 2144937Y etc.According to the shoe-pad that this class technical scheme is made with row, ventilatory, exist employing material category and manufacture craft step preface more mostly, structure is comparatively complicated, thereby cost of manufacture is than problems such as height.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and manufacture craft is simple and direct, the dry and comfortable shoe-pad of exhaust with low cost.

The utility model can be realized by following scheme: the dry and comfortable shoe-pad of a kind of exhaust, comprise surface layer and sandwich layer, it is characterized in that sandwich layer adopts and to have after certain flexible foamed sheet is sandwiched in two lining centres, sew up or bonding along periphery, and do not do to sew up or adhesion process as air inlet reserving at least one openning corresponding to the heel posterior direction; Also do to sew up or adhesion process corresponding to pin waist hanging part and toe trample part at shoe-pad; Described sticking and preferably adopt thermocompression bonded and, also can adopt other harmless flexible adhesives to make adhesion process; The shoe-pad surface layer preferably adopts to be convenient to add heat bonding and to have certain packing, again better gas permeability, the good nonwoven of feel are arranged, and also can adopt cotton to knit or the blending cloth; Foamed sheet thickness as sandwich layer is preferably 3～5 millimeters; Air inlet is not sewed up as the shoe-pad periphery or length not sticking and part preferably is not less than 10 millimeters, is not more than 25 millimeters; The middle part of air inlet preferably is in take over 4～8 millimeters position of shoe-pad longitudinal centre line.

Heel landed earlier when the utility model utilized people to walk, thereafter, the characteristics that foot waist and ball portion just land in succession, when heel contact, at first with air inlet compressing blocking-up, along with impetus is moved forward to ball portion through sufficient waist gradually by heel portion, air full in the core material will be pushed to the ball portion direction gradually, and in shoe-pad surface layer space, overflow, thereby the moist sweat band of gas that is detained between ball portion and the toe seam is gone out.In progressively reach process of vola portion pressure, when sufficient waist began to land, heel portion pressure reduced gradually and disappears.So the foamed plastics of shoe-pad sandwich layer just returns to the original form gradually below heel portion, thereby form a local decompression zone at this.So under the atmospheric pressure effect, the air at heel rear portion just enters the foamed plastics sandwich layer from air inlet, for the next one is pressed, the release gets ready.Because the common perspire of people's foot root is few, so its ambient gas is than the ball portion drying.When people walk, rely on the above-mentioned inlet and outlet action that goes round and begins again, just make the moisture of ball portion be able to continuous discharge.

Adopt the utility model, can make often to keep dry and comfortable comfortable in the footwear; Only need two kinds of primary raw materials owing to produce this product, manufacture craft is simple and convenient in addition, every kind of equal positive and negative symmetry of specification product, can left and rightly exchange, match and wear, so only need to realize the mechanization production in enormous quantities once cover frock, mould, production efficiency is high, thus with low cost, have significantly economic benefit.

Accompanying drawing 1 is the utility model front view and Figure of abstract

Accompanying drawing 2 is left views

Accompanying drawing 3 is upward views

In the accompanying drawing, 1 is stitching of toe trample part or bonding place, and 2 is surface layer, and 3 is stitching or the bonding place corresponding with sufficient waist hanging part, and 4 is shoe-pad periphery cementing line, and 5 is air inlet, and 6 is the foamed plastics sandwich layer.

Below, with embodiment the utility model is further described with reference to the accompanying drawings:

Embodiment 1

To and be sandwiched in therebetween foamed sheet as sandwich layer 6 by required shoe-pad size stamping-out or be cut into shape shown in Figure 1 as the nonwoven cloth of surface layer 2 earlier, and after its perimeter alignment, put into the hot pressing matched moulds that adopts prior art to make and carry out hot pressing and handle and get final product.

On the hot pressing matched moulds, counterdie should make the shape that makes toes trample part 1, sufficient waist hanging part 3 and shoe-pad periphery cementing line 4 be higher than all the other positions, it is good not causing the position pressurized that air inlet 5 and other should not be bonding when guaranteeing to carry out hot pressing and producing thermal deformation; Air inlet can be one, also can be two.If need two air inlets, can on the hot pressing matched moulds, increase a hot pressing chalaza from these air inlet 5 middle parts, air inlet is divided into two; The middle part of air inlet preferably is in take over 6 millimeters position of shoe-pad longitudinal centre line.

Embodiment 2

To knit or blending cloth and be sandwiched in therebetween foamed sheet as sandwich layer 6 by required shoe-pad size stamping-out or be cut into shape shown in Figure 1 as the cotton of surface layer 2 earlier, after its perimeter alignment, adopt the method for sewing up, sew up along peripheral cementing line 4, and reserve air inlet 5; Toes trample part 1, sufficient waist hanging part 3 etc. are all sewed up one by one; Air inlet 5 can be one, also can be two.If need two air inlets, can increase a stitch points in these air inlet 5 middle parts, air inlet is divided into two; The middle part of air inlet preferably is in take over 6 millimeters position of shoe-pad longitudinal centre line.

Embodiment 3

To knit or blending cloth and be sandwiched in therebetween foamed sheet as sandwich layer 6 by required shoe-pad size stamping-out or be cut into shape shown in Figure 1 as the cotton of surface layer 2 earlier, after its perimeter alignment, adopt the bonding method of neoprene adhesive, carry out bondingly along peripheral cementing line 4, and reserve air inlet 5; Toes trample part 1, sufficient waist hanging part 3 etc. are located, and can adopt injection device that adhesive is injected above-mentioned 1,3 two position, and be bonding in addition one by one; Air inlet 5 can be one, also can be two.If need two air inlets, can increase a bounding point in these air inlet 5 middle parts, air inlet is divided into two; The middle part of air inlet preferably is in take over 6 millimeters position of shoe-pad longitudinal centre line.
