Waterproof Shoe Structure

Abstract

A waterproof shoe structure includes a sole, a vamp mounted on the sole, and a waterproof lining mounted on the vamp. The vamp is provided with a plurality of vent holes. The waterproof lining has a surface provided with a plurality of convex portions and a plurality of concave portions between the convex portions. Each of the convex portions is higher than each of the concave portions. Each of the convex portions is provided with a through hole connected to each of the vent holes of the vamp. The through hole of each of the convex portions and each of the vent holes of the vamp are integrated to connect an inner space of the vamp to an ambient environment.

1 . A shoe structure comprising:
 a sole;   a vamp mounted on the sole; and   a waterproof lining mounted on the vamp;   wherein:   the vamp is provided with a plurality of vent holes;   the waterproof lining has a surface provided with a plurality of convex portions and a plurality of concave portions between the convex portions;   each of the convex portions is higher than each of the concave portions;   each of the convex portions is provided with a through hole connected to each of the vent holes of the vamp;   the through hole of each of the convex portions and each of the vent holes of the vamp are integrated to connect an inner space of the vamp to an ambient environment;   when rainwater drops, the rainwater directly flows down from the convex portions to the concave portions of the waterproof lining, without staying on the convex portions;   when the rainwater drops onto the through hole of each of the convex portions, the rainwater does not enter the through hole of each of the convex portions by a capillary action;   when the vamp is compressed by an external force, air in the inner space of the vamp is forced to flow through each of the vent holes of the vamp and the through hole of each of the convex portions, and is drained outward from the through hole of each of the convex portions into the ambient environment; and   when the vamp is released and restored to an original state after the external force disappears, the air from the ambient environment is introduced through the through hole of each of the convex portions and each of the vent holes of the vamp into the inner space of the vamp.   
     
     
         2 . The shoe structure of  claim 1 , wherein each of the convex portions has a semispherical shape. 
     
     
         3 . The shoe structure of  claim 1 , wherein the through hole of each of the convex portions is disposed at a vertical state. 
     
     
         4 . The shoe structure of  claim 1 , wherein the through hole extends downward from a central position of a top face of each of the convex portions. 
     
     
         5 . The shoe structure of  claim 1 , wherein the through hole of each of the convex portions has a small diameter. 
     
     
         6 . The shoe structure of  claim 1 , wherein each of the vent holes extends through a whole thickness of the vamp, and the through hole extends through a whole thickness of each of the convex portions. 
     
     
         7 . The shoe structure of  claim 1 , wherein the waterproof lining is mounted on a helmet. 
     
     
         8 . The shoe structure of  claim 1 , wherein the waterproof lining is mounted on a raincoat.
