Abstract

A functional shoe pertains to a cushioning function and an air circulation function, which integrally performs the cushioning function and the air circulation function. The functional shoe includes: an insole (110) and a midsole (120) having a tunnel portion (122). The tunnel portion (122) has a lower surface (122a) and an upper surface (122b) having a predetermined angle (α) with the lower surface (122a); an outsole (130) having an anti-slip tread (132); a foldable resilient member (140) having a support portion (142) for supporting the lower surface (122a) of the tunnel portion (122), and a rotating portion (144). The rotating portion (144) is resiliently folded by the load being applied thereto; a sealing member (150); and an air channel (160) having one end communicated to the closed tunnel (122) and the other end located at the front end of the insole (110).

Claims

1. A functional shoe having cushioning and air circulation functions, comprising:

an insole (110) having an upper surface to which leather uppers (102) are adhered;

a midsole (120) including a tunnel portion (122) formed at a rear end thereof, and having a lower side surface (122a) in contact with a lower surface of the insole (110) and formed parallel to the ground surface and an upper side surface (122b) configured to form a predetermined angle (α

) with respect to the lower side surface (122a);

an outsole (130) having a tread (132) adhered to a lower surface of the midsole (120) and configured to prevent slippage thereof;

a foldable resilient member (140) having a support section (142) configured to support a lower side surface (122a) of the tunnel portion (122) and a pivot section (144) configured to support an upper side surface (122b) of the tunnel portion (122), wherein the pivot section (144) is resiliently folded by an applied load;

a sealing member (150) installed to seal the tunnel portion (122); and

an air channel (160) having one end in communication with the sealed tunnel portion (122) and the other end disposed at a front side of the insole (110).

2. The functional shoe having cushioning and air circulation functions according to claim 1, wherein the foldable resilient member (140) comprises:

a pivot shaft (145);

the support section (142) and the pivot section (144) hinged by the pivot shaft (145); and

a resilient section (146) having a torsional coil spring (146a) inserted into the pivot shaft (145), a first extension unit (146b) extending from the torsional coil spring (146a) to support the support section (142), and a second extension unit (146c) extending from the coil spring (146a) to support the pivot section (144).

3. The functional shoe having cushioning and air circulation functions according to claim 1, wherein the foldable resilient member (140) is a flat spring in which the support section (142) and the pivot section (144) are integrally formed.

4. The functional shoe having cushioning and air circulation functions according to claim 1, wherein a discharge check valve (162) is installed at one end of the air channel (160), and a suction check valve (164) is installed at one side of the sealing member (150).

5. The functional shoe having cushioning and air circulation functions according to claim 1, wherein a suction check valve (164) is installed at one end of the air channel (160), and a discharge check valve (162) is formed at one side of the sealing member (150).

6. The functional shoe having cushioning and air circulation functions according to claim 1, wherein the midsole (120) is curved such that a front side and a rear side are spaced apart from the ground surface.

7. The functional shoe having cushioning and air circulation functions according to claim 1, wherein the midsole (120) has at least one high elastic or solid reinforcement member (170) configured to maintain a shape of the midsole (120) and prevent a fracture of the foldable resilient member (140) from a front side of the midsole (120).

8. The functional shoe having cushioning and air circulation functions according to claim 1, wherein the insole (110) contains an inorganic material of emitting far-infrared light or is anion-treated.

9. The functional shoe having cushioning and air circulation functions according to claim 2, wherein a discharge check valve (162) is installed at one end of the air channel (160), and a suction check valve (164) is installed at one side of the sealing member (150).

10. The functional shoe having cushioning and air circulation functions according to claim 3, wherein a discharge check valve (162) is installed at one end of the air channel (160), and a suction check valve (164) is installed at one side of the sealing member (150).

11. The functional shoe having cushioning and air circulation functions according to claim 2, wherein a suction check valve (164) is installed at one end of the air channel (160), and a discharge check valve (162) is formed at one side of the sealing member (150).

12. The functional shoe having cushioning and air circulation functions according to claim 3, wherein a suction check valve (164) is installed at one end of the air channel (160), and a discharge check valve (162) is formed at one side of the sealing member (150).

13. The functional shoe having cushioning and air circulation functions according to claim 6, wherein the midsole (120) has at least one high elastic or solid reinforcement member (170) configured to maintain a shape of the midsole (120) and prevent a fracture of the foldable resilient member (140) from a front side of the midsole (120).
