Breathing insole with ventilating function

Abstract

This invention relates to a breathing insole with ventilating function, which is made of the shoe-shaped upper & lower insoles and porous layer; its features are as follows: when the upper insole is molded, the containing trough is made in concave in the central part of its bottom according to shape of shoe, frame around containing trough is also formed so that upper and lower insole are glued and form an air chamber. Several elastic protruding bodies are fixed in the arch of containing trough of this upper insole; porous layer contacting sole of the foot is glued onto upper insole. In addition, based on upper insole and porous layer, several inlet holes and outlet holes are respectively made in the heel portion and in the front thenar portion of foot; as the breathing insol with ventilating function is placed into shoes, the continuous trample and lift-up by the shoe wearer while walking may push cool air around the heel portion into the front thenar portion of the foot, the wet and hot air around the front thenar portion of foot inside shoe can be exhausted, therefore, shoes may keep ventilating and discharging heat effectively.

1 . A breathing insole with ventilating function, which is made of shoe-shaped upper and lower insoles and porous layer (cloth or leather) ; its features are as follows: 
 When the upper insole is molded, one containing trough is made in concave in the central part of bottom according to shape of shoe, and forms frame around containing trough so that the frame of upper insole is glued onto lower insole and makes air chamber, several elastic protruding bodies fending off air chamber are fixed at the arch of the upper insole, one porous layer contacting sole of the foot is glued onto upper insole. In addition, upper insole and porous layer, set several inlet holes in heel portion and outlet holes in the front thenar portion of foot; when the wearer is walking, the continuous trample and lift-up may push cool air around the heel portion into the front thenar portion and exhaust wet and hot air around the front thenar portion inside the shoes, therefore, the shoes may keep ventilating.    
     
     
         2 . As described in  claim 1 , this invention relates to a breathing insole with ventilating function, wherein one containing trough is made in concave in the central part of bottom according to the shape of shoe, and form frame around the containing trough, the containing trough is mesh pattern supporting body, bottom of each interlayer of the mesh pattern supporting body has concave gap slot, however, mesh shape of the mesh pattern supporting body can be square, circular or in any other irregular geometric shape, mesh can be made into as passing-through hole or one end contacting porous layer is closed.  
     
     
         3 . As described in  claim 1 , the invention relates to a breathing insole with ventilating function, wherein one containing trough is made in concave in the central part of its bottom according to the shape of shoes, and form frame around the containing trough, the containing trough is fixed by several grooves to guide air to add air contents of air chamber.  
     
     
         4 . As described in  claim 1 , this invention relates to a breathing insole with ventilating function, wherein one containing trough is made in concave in the central part of its bottom according to the shape of shoe, and form frame around containing trough, the protruding points are equally distributed over containing trough so as to fend off upper and lower insole for better air convection.  
     
     
         5 . As described in  claim 1 , this invention relates to a breathing insole with ventilating function, wherein in this case, the lower insole is molded with concave containing trough in the central part of the bottom according to the shape of shoe and forms frame around containing trough, and several protruding bodies are fixed at the arch of the lower insole so as to fend off air chamber, and then the porous layer with several inlet holes in the heel portion and outlet holes in the front thenar portion of the foot is glued on the top side of the frame of the lower insole, and make air chamber for breathing insole.  
     
     
         6 . As described in  claim 5 , the invention relates to a breathing insole with ventilating function, wherein in this case the insole is glued by porous layer and lower insole, concave containing trough of the lower insole can be made as equally distributed protruding points, air guide grooves or mesh pattern supporting body, the mesh shape of the mesh pattern supporting body is designed as concave at one end contacting with porous layer.
