Abstract
A sole structure with complex waterproof and gas-permeable material and a manufacturing method thereof. A plane blank having a through with a pattern of an array is provided. At least one waterproof and gas-permeable film is combined with the plane blank to cover the through hole. The plane blank with the film is located in a predetermined position inside a sole mold. Then a molten plastic material is filled into the mold to associate the plane blank and the film with the plastic material to form an integral large substrate of the sole. The sole provides waterproof and gas-permeable effect to prevent water from tarrying between the large substrate and middle substrate.
Description
SOLE STRUCTURE W I TH COIV~LF~ WATERPROOF AND GAS - PERMEABLE MATER I AL.
A1~1D MANUFACTUR I NG METHOD TkIEREOF
BACKGROUND OF TEE INVENTION
Tl~e present invention is related to a watezpzoof and gas-permeable sole structure az~d a manufactuzix~g method thereof, and more particularly to an impzoved sole structure which overcomes the problem that the vapor tarries between the large substrate and the middle subst rate ( or insole ) of the convent Tonal gas-permeable shoe.
The conventional waterproof gas-permeable film such as Gone-Te,~ film ( so-called century fabric ) is composed of two binds of unique polymers. One of the polymers is a nearly thermoplastic polyurethane ( TPU ) material which provides high stiffness. The other is ePTF'E which provides waterproof and gas-permeable effect.
Nine billion micro-voids are distributed oven each square inch azca of such material. The size of such void is two hundred millionth the size of liquid water molecule- However, the size of such void is seven hundred times the size of vapor. Therefore, the water molecule cannot pass through the voids, while the~vapox is permitted to be exhausted through the voids. The waterproof gas-permeable film such as Gore-Tex can be attached to inner side of nylon and other fabric for making clothes, shoes, gloves, etc. tv achieve windproof, waterproof and gas-permeable characteristics. A user wearing such clothes or shoes can keep dry, warm and comfortable.
Fig. 1 shows that the waterpzoof gas-pezmeable film such as Gore-Tex, is adhered to inner side of a sole fox waterproof effect and exhaustion of vapor to keep a user's feet dry. The sole 10 includes a large substrate 11, a middle substrate 12 connected on the large substrate 11 and an insole T3 overlaid on the middle substrate 12. The la,xge substzate 11 is generally made of thermoplastic rubber ( TPR ) material which is cheaper.
Alternatively, the large substrate 11 can be made of TPU or 1?VG.
In the conventional measure, the Gore-Tex has a characteristic closer tp that of TPU so that the Gore-Tex can hardly combined with TPR material. Therefore, in manufacturiztg, the more expensive waterproof and gas-permeable film 40 is adhered between the large substrate 11 aztd the middle substrate 12 to prevent the water from entering the middle substrate 12 and the insole 13. ,As known by those skilled in this field, izt actual use, although the vapor is isolated from the inner layer of the shoe, the water still often xemaiz~s between the large substrate 11 and the middle substrate 12 in the positions as shown by the arrows of Fig. 1. This makes a user feel uncomfoztable. Moreover, in use of the shoe, the sole wil 1 bear great bending force and impact. Therefore, it is quite hard to combine the materials with each other with glue.
In the above s t ructure, the waterproof and gas-permeable f i lm 40 is adhered to the sole 10 to isolation of water and exl~zaustion of vapor of a user's feet. However, such structure fails to overcome the problem that the water tarries between the large substrate 11 and the middle substrate 12. The melting point of the large substrato z 11 is about I80 °C . The melting point of the watezproof and gas-permeable film 40 is about 120 °C . In addition, these two material s are incompat ibl a wi th each other . As a resin t , dur ing the molding procedure, when filling the material of highez temperature into the sole, the waterproof and gas-permeable film 40 is often previously molten or unexpectedly damaged. Therefore, it is hazd to associate the watezproof and gas-permeable f i lm 40 wi th the large substzate 11. This obstructs the waterproof and gas-permeable film 40 from successfully associating with the large substzate ll.

It is therefore a primary object of the present invention to provide a sole structuze with complex waterproof and gas-pez~meable taatezial az~d a manufacturing method thezeof. The sole provides watezp,roof and gas-permeable effect to prevent watez fzvm tazzying between the lazge subst rate and middle subst rate of the sole. A plane blank l~avit~g a through with a pattern of an array is provided. A
waterproof and gas-permeable film made of a material identical to or compat ible wi th the material of the plane blank is combined wi th the plane blank to cover the through hole. The plane blaniC with the film is located in a predetermined position inside a sole mold. Then a molten plastic material is filled into the mold to associate the plane blank and the film with the plastic material to form an integral sole.
According to the above object, the sole stz~uctuze includes a large substrate and a middle substzate overlaid on an inner face of the large substrate. The plane blank combined with the waterproof and gas-permeable film is disposed in a predetermined position on inner face of the large substrate. The water on outez side of the large substrate is isolated andprevertted from getting into the shoe through the through hole of the large substrate. However, t-he air can pass through the waterproof and gas-permeable f i lm into the shoe to achieve gas-permeable and humidityproof effect. The area of the plane blank is larger than that of the film, The molten plastic material at high temperature is fused with the peripheral section of the plane blank, However, by means of a meld core, the plastic material is isolated from the film without contacting and damaging the film.
In the above structure, multiple fixing holes are formed along the peripheries of the plane blank. When the plastic material is filled into the mold, the plastic matez~ial can fill iztto the fi,~iztg holes to form a key stzucture for firmly associating the plane blank with the plastic material.
In addition, a sheet material such as a mesh tissue sheet yr porous sheet with high stiffness ( such as TPU sheet ) is associated wi th at leas t one face of the f i lm to reinforce the f i lm and prolong us ing 1 i fe of tlae f i lm, The preseztt invention can be best understood through the fol lowing descript iozt aztd accompaztying drawings wherein:

Please refez to Figs. 2 and 3. The sole structure 10 with complex waterpz~oof and gas-permeable material of the present invention includes a Iarge substrate 11. The large substrate 11 can be select ively nnade of any of TPR, PVC, TPU and the 1 ikes . A middle substrate 12 and/or an insole 13 are overlaid on the large substrate 11, A predetermined section of inner face of the Iarge substrate 11 is formed wi th through holes 14, 15 which can have any geometric profile. The through holes 14, 15 axe arranged on front half, rear half oz other section of the large substrate 11.
A plane blank 16 combined with waterproof and gas-pex~neable film 40 is laid on the inner face 111 of the large substrate 11 to correspondingly cvvez the through holes 14, 15. Tl~e plane blank 16 is made of a material identical tv or compatible with the material of the waterproof and gas-permeable film 40, The plane blank I6 is foamed with an array-type through hole 17 corresponding tv the through hole 14 yr 15 of the large substrate, Tn this embodiment, the array-type through hole 17 has an array of multiple oblique slats arranged as a blind. Such array prevents alien articles from di rect ly get t ing into the sloe through the through hole 17, The f i lm 40 is fi,~edly combined with the plane blaztk 16 by means of pressing, high fzequency or ultrasonic wave. The film 40 at least covers the through hole 17 of the plane blank 16. In principle, the area of the plane blank ~6 is larger than the area of the film 40. In a preferred embodiment, a sheet material 22 such as amesh tissue sheet or reizzforciztg sheet made of stiffer material ( such as TFU sheet ) is associated with at least one surface of the film 40. The sheet material 22 is attached to the film 40, In another embodiment, the position relationship between the film 40 and the sheet material 22 and the numbez thereof are exchangeable and variable. In other wards, the sheet material 22 can be arranged between the large substrate 11 and the film 40 ( not shown ) or between the film 40 and the middle substrate 1,2. Alternatively, the sheet material 22 caza be laid on both the upper and lower faces of the film 40.
Figs. 4 and 5 show the improved sole structure to which the plazte blank I6 combined with the film 40 is applied. The water on outer face 112 of the large substrate 11 is isolated and prevented from getting into the thzough hole and tazz'ying between the inzaez side of the large substrate ~l and the middle substrate 12. However, the vapor generated by the foot of a user i s permi t ted to be exhaus ted from the large subst rate 11 through the waterproof and gas-permeable film 40 at the througlz hole 17 of the plane blank 16.
heferring to Fig. 6, the charactezistic of the material of the large substrate 11 is different from that of the plane blank I6.
Therefore, they may be hard to associate with each other and incompatible. Accordingly, they are associated by a method including step (a), step (b) and step (c). In step (a), a sheet material 22 is laid between the plane blaztk 16 and the film 40 or on the inner face of the film40. The sheet material 22 can be stiffer sheet body such as TPU porous sheet densely formed wi th perforations or raesb tissue sheet. The stiffness of the TPU sheet can reinforce the plane blank 16 ox film 40 tv resist against intrusion or damage of rocks or other alien articles under the sole.
In step (b), the plane blank 16 associated with the film 40 and the sheet matczial 22 is located in a predetermined position inside a sole mold 20. An isolating section oz pile 21 is uscd to just cover the peripheral area of the through hole 17 of the blank 16.
In step (c), a plastic ( softened ) material 30 is filled or placed into the mold 20 foz integrally n~oldiz~g the large substzate 11. The plastic material 30 is integrally associated with the peziphery of the plane blank 16. 1n the molding proccduze, the plastic material 30 is isolated from the section of the film 40 correspoztding to the through hole 17 by the mold 20. Thezefore, the plastic matezial 30 will not contact with or damage the section of the film 40.
In order to solve the problem existing in the prior art that tl~e water tends to tazzy inside the large substrate 11 or between the large substrate 11 and the middle substrate 12, tlae present iztvention has the following structural chazactexistics:
s 1. The large substrate 11 is fozmed with through holes 14, 1S
zz~ predetern~iz~ed posi t ions . A plane bl aztk 16 combined wi th a film 40 is located on inner surface 1~1 of the large substrate 11 corresponding to the position of the through hole I4.

Alternatively, the sheet material 22 caza be laid on both the upper and lower faces of the film 40.
Figs. 4 and 5 show the improved sole structure to which the plazte blank I6 combined with the film 40 is applied. The water on outer face 112 of the large substrate 11 is isolated and prevented from getting into the thzough hole and tazz'ying between the inzaez side of the large substrate ~l and the middle substrate 12. However, the vapor generated by the foot of a user i s permi t ted to be exhaus ted from the large subst rate 11 through the waterproof and gas-permeable film 40 at the througlz hole 17 of the plane blank 16.

Therefore, they may be hard to associate with each other and incompatible. Accordingly, they are associated by a method including step (a), step (b) and step (c). In step (a), a sheet material 22 is laid between the plane blaztk 16 and the film 40 or on the inner face of the film40.

In step (c), a plastic ( softened ) material 30 is filled or placed into the mold 20 foz integrally n~oldiz~g the large substzate 11. The plastic material 30 is integrally associated with the peziphery of the plane blank 16. 1n the molding proccduze, the plastic material 30 is isolated from the section of the film 40 correspoztding to the through hole 17 by the mold 20. Thezefore, the plastic matezial 30 will not contact with or damage the section of the film 40.
In order to solve the problem existing in the prior art that tl~e water tends to tazzy inside the large substrate 11 or between the large substrate 11 and the middle substrate 12, tlae present iztvention has the following structural chazactexistics:
s 1. The large substrate 11 is fozmed with through holes 14, 1S
zz~ predetern~iz~ed posi t ions . A plane bl aztk 16 combined wi th a film 40 is located on inner surface 1~1 of the large substrate 11 corresponding to the position of the through hole I4.
2. The plane blank 16 is fvxmedwith an array-type through hole 17 correspoxtding to the through hole I4. The f i lra 40 at least covers the array- type through hole 17, permi t t iz~g the vapor of the foot to be exhausted from the large substrate through the through hole.l7 of the film 40. Howevez, the water on outer side of the sole is isolated by the film ~0 and prevented from getting Into the shoe through the sole.
3. Tkze area of the plane blank 16 should be larger than that of the fi lm 40. Zn step (b) , the isolat ing sect ion or pi le 21 presses the pl ane blank 16 to cvvez the f i lm 40. Therefore, the filled high temperature plastic material 30 will flow to associate with the peripheral area of the plane blank 16, while the plastic material 30 will z~ot contact with and damage the section of the film 40 coxzesponding to the through hole 17.
1~igs. 7, 7A, 8 and 8A show a partially modified embodiment of the present invention. ,In this embodiment, multiple fixing holes 18, 23 are foxraed along the periphery of the plane blank 16 or the sheet material 22, When the plastic material 30 is filled into the mold 20, the plastic material 30 can freely flow into the fixing holes 18, 23. Accvzdingly, an insertion key structure can be formed' between the plane blank 16 oz sheet material 22 and the plastic material 30 as shown in Figs. 9 and 9A. The periphery of the sheet material 22 can be al so formed wi th an array fixing holes 23 as the plane blank 16. xhe fixing holes 23 are al igncd wi th the f fixing holes 18 of the plane blank 16. When filling the plastic material 30, the plastic material 30 can be also well associated with the sheet material 22. Accordingly, the lazge substrate 11, plane blank 16, film 40 and the sheet material 22 can be truly integrally adhered to each otk~ez.
