See also shown in Fig. 1,2, the utility model mainly is by the formed bed course 20 of going up of continuity air bag foaming thing (as PU), compound with the formed underlayer of the reclaimed materials of the free-standing air bag foaming thing (as EVA) of its below 10, and form a compound slot type pad.And go up bed course 20 is to form two symmetrical row's shape bar bodies 21 with wavy cutting, and this row's shape bar body 21 some wavy bodies 211 that are arranged in parallel that are tools are connected with along connection strap 212 and form (as Fig. 2); Last bed course 20 through cutting then forms two separable row's shape bar bodies 21, glue together with its long limit and after aliging in the long limit of underlayer 10 again and the connection strap 212 of the row's of cutting shape bar body 21 to form compound pad (as Fig. 1).

Please cooperate and consult shown in Figure 3ly, it is the cut-away view of the utility model embodiment.Compound pad through being composited, its upper strata is formed by some wavy parallel bodies 211, and adjacent wavy body 211 is ventilating groove 30 with underlayer 10 formed grooves; And the lower floor of compound pad is a underlayer 10, and its reclaimed materials by free-standing air bag foaming thing (as EVA) is formed; The utility model is able to by widely applying reclaimed materials, to meet the environmental protection demand; And high unit price but be suitable for the material of human body sense of touch, it is continuity air bag foaming thing (as PU), by the wavy mode that cuts, make both sides respectively stay a connection strap 212, peel off and cut back a slice and can be two layers continuity air bag foaming body and use, its material is used to greatest extent, get so that it reduces cost.

See also shown in Fig. 4,5, it is stereoscopic figure and the generalized section of another embodiment of the utility model.Last bed course 20 is provided with some most air-vents 40 to increase its air permeable effect; And air-vent 40 shared volumes are last bed course 20 half, therefore, though design makes the thickness of upper and

lower bed course

20,10 of the present utility model identical by this, but the volume of last bed course 20 then reduces 1/2nd relatively, only account for 1/4th of whole Air-permeable mattresses, material for high price and suitable human body contact also is able to a large amount of savings, and makes it also meet full use on the industry.

Please cooperate and consult Fig. 6 to shown in Figure 14, wherein, the change of shape schematic diagram of Fig. 6 when Figure 8 shows that PU material foaming thing pressurized is when its pressurized, because its elasticity is good and the relation of tool continuity air bag, change of shape is big, and especially cross directional variations will be unfavorable for that the user uses, so the dealer has its frothing percentage of reduction, to improve its amplitude of variation, and after the pressure releasing, lengthwise phase pressurized still can reinstatement.And Fig. 9 is to shown in Figure 11, change of shape schematic diagram when it is EVA material foaming thing pressurized, when its pressurized, because its tool stand alone type air bag, elasticity is relatively poor, distortion also mostly is linear deformation (thickness dwindles) greatly, and after the pressure releasing, under long-term pressure, EVA produces permanent deformation, can't restore to the original state.Change of shape schematic diagram when Figure 12 to Figure 14 then is the utility model embodiment pressurized, because the PU material of last bed course 20 is cemented in underlayer 10, the situation of its pressurized transversely deforming is improved, but its elasticity, sense of touch are at all unaffected, and underlayer 10 also on average bears because of the pressure of last bed course 20, the irregular deformation situation of its pressurized is uniformly distributed in underlayer 10, so also must be improved.

The particularly important is, bed course 10 of the present utility model is owing to adopt free-standing air bag foaming thing, and its hot-workability is good, behind upper and

lower bed course

20,10 gummeds, can hot pressing make and want the shape finished, not influenced because of the not machinability of last bed course 20, and underlayer 10 more is fixedly arranged on lower floor, does not contact with human body, and as previously mentioned, it accounts for most of volume of the present utility model, can use reclaimed materials in a large number, has good environment-friendly function.

Please cooperate and consult shown in Figure 15ly, it is the vertically ventilative view of the utility model embodiment; The compound back of the utility model forms some ventilating grooves 30 in underlayer 10 and upward between the bed course 20; If is example with the shoe-pad, when both feet place on the shoe-pad that the utility model makes, i.e. bed course 20 is gone up in contact, and because of it is made for the PU material, makes foot have comfort; And double-legged weight application presses down

bed course

20, and 30 air that will originally be stored in the ventilating groove 30 because of being squeezed of the ventilating groove that this moment, composite cushion had are from bottom to top discharged, and the interior air of footwear is circulated, and reach its vertically ventilative purpose.

See also shown in Figure 16ly again, it is the laterally ventilative view of the utility model embodiment; When external force imposes on underlayer 10 of the present utility model and it is pressed down, and it is mobile that the former air of depositing in the ventilating groove 30 is made progress, and because of ventilating groove 30 of the present utility model be about one to be communicated with structure, ascending air is able to rapidly to the circulation of scattering of ventilating groove 30 left and right directions, makes that gas is reached horizontal circulation and ventilative purpose in the footwear; Therefore, the utility model has concurrently vertically and horizontal air permeable effect simultaneously, makes it be reached best gas permeability, and this is the otherness place of the utility model with the person's of commonly using maximum.

Please cooperate and consult Figure 17 and shown in Figure 180, it is an absorption stress action schematic diagram of the present utility model; If with the shoe-pad is example, when both feet are when placing the upper strata of commonly using shoe-pad to walk displacement, to composite pad be met with stresses produce relative torsional deformation because of both feet move and press down, and can't effectively absorb or dispersive stress will make foot produce discomfort, and not meet the ergonomics principle because of it; So the utility model especially at this point, provides the action effect of a dispersive stress, makes it be able to complete absorption stress.It is the ventilating groove 30 that each 211 of wavy body of the present utility model is provided with the tool open space, and stress is done the time spent, wavy the body 211 that is acted on produces distortion relatively, the ventilating groove 30 that a then wavy body is 211 is absorbed stress fully, and applied stress can't concentrate on pad, wavy body 211 is produced squeeze phenomenon mutually; Therefore, the design that the utility model is special by this must make the complete absorption stress of pad, makes sole not have any discomfort sense, more meets the ergonomics principle.

Effect of the present utility model can be summarized as follows:

1, promote the pad quality: the utility model merges characteristic, the advantage of EVA and PU material, makes that it has that processability is good, gas permeability and splendid effects such as sense of touch; But the effect of the utility model maximum is:

A: the air permeable effect of promoting pad: because of the utility model has laterally and air permeable effect longitudinally simultaneously, promptly during the pad pressurized, the former air that is stored in the ventilating groove make progress and about circulate, make air permeable effect thereby raising.

B: absorb stress fully, avoid foot to squeeze the discomfort of generation because of pad: promptly if the utility model is when being subjected to applied stress to make it produce deflection, its applied stress then is entirely its ventilating groove and absorbs, and sole does not then have any discomfort sense, makes it more meet the ergonomics design.

2, economy: the utility model can use reclaimed materials and non-reclaimed materials to form composite pad simultaneously, and reclaimed materials can reduce cost, and the volume of non-reclaimed materials is saved, and makes it reduce manufacturing cost, also can save the requirement that overall volume reaches economy simultaneously.

3, the feature of environmental protection: the utility model can adopt a large amount of reclaimed materials (EVA) as underlayer 10, breaks through to commonly use the EVA reworked material and use restriction, makes it increase material recovery and recycle value, to reduce manufacturing cost and then to reach the purpose of environmental protection.
