Hidden drainage system for shoes
A hidden drainage system for shoes, configured on the outsole of a shoe, in which the two sides of the outsole are provided with a plurality of curved sections that are curved inward; the top of the outsole is provided with a plurality of transverse drainage troughs and several longitudinal drainage troughs; each of the transverse drainage troughs extends along the direction of the width of the outsole, and both ends are communicated with each of the curved sections, so that the two ends of each of the transverse drainage troughs will not be exposed on the side face of the outsole; the longitudinal drainage troughs extend along the length of the outsole and are communicated with each of the transverse drainage troughs; thus, water entering the shoe will flow into each of the transverse and longitudinal drainage troughs, and be discharged from each of the transverse drainage troughs.
1. A hidden drainage system for shoes, configured on an outsole of a shoe, having the following characteristics:
two sides of an instep portion of the outsole are provided with a plurality of curved sections that are curved toward a heel portion of the outsole; a top of the outsole is provided with a plurality of transverse drainage troughs and one or more longitudinal drainage troughs; each of the transverse drainage troughs extends along a direction of a width of the instep portion of the outsole, and both ends of each transverse drainage trough are communicated with a respective curved section, so that the two ends of each of the transverse drainage troughs are not exposed on a side face of the outsole and are exposed on a top face of the plurality of curved sections, thereby hiding the two ends of each transverse drainage trough, and the extending path of the transverse drainage troughs is in the shape of an arc extending in a forward direction and each of the curved sections is configured with a tilted surface directed to the heel portion of the outsole and the two ends of each transverse drainage trough extend to each tilted surface; the longitudinal drainage troughs extend along the length of the outsole and are communicated with each of the transverse drainage troughs; thus, water entering the shoe will flow into each of the transverse and longitudinal drainage troughs, and be discharged from each of the transverse drainage troughs.
2. The structure system in claim 1 , wherein the arc-shaped extending path of the transverse drainage troughs protrudes toward the front end of the outsole, and the two ends of each of the transverse drainage troughs corresponds to the direction of the rear end of the outsole.
3. The structure system in claim 1 , wherein the top of the outsole is further configured with a supporting piece.
4. The structure system in claim 3 , wherein the top of the outsole is configured with two longitudinal drainage troughs and the supporting piece is positioned between the two longitudinal drainage troughs.
5. The structure system in claim 4 , wherein said outsole comprises an elastic layer and an anti-slip layer, said elastic layer being laminated on the anti-slip layer, and each of the transverse and longitudinal drainage troughs and the supporting piece being configured on the elastic layer.
6. The structure system in claim 5 , wherein the tilted surface of each curved section is configured on the elastic layer.
7. The structure system of claim 3 , wherein the outsole comprises an elastic layer and an anti-slip layer, the elastic layer is laminated on the anti-slip layer, and each of the transverse and longitudinal drainage troughs and the supporting piece is configured on the elastic layer.
8. The structure system in claim 1 , wherein said outsole comprises an elastic layer and an anti-slip layer, said elastic layer being laminated on the anti-slip layer, and each of the transverse and longitudinal drainage troughs are configured on the elastic layer.
9. The structure system in claim 8 , wherein the tilted surface of each curved section is configured on the elastic layer.
