Self-ventilating footwear

Abstract

Self-ventilating footwear, especially applicable to sports trainers, includes a sole with a chamber ( 4 ) in communication with the exterior by means of one-way valves ( 8 ) that allow air to exit the chamber ( 4 ) to the outside and prevent the ingress thereof towards the inside. This chamber ( 4 ) communicates with the inside ( 5 ) of the footwear ( 1 ) via holes ( 6 ) made in the insole ( 3 ) that delimits the chamber ( 4 ) at the top, the holes ( 6 ), in combination with elastic patches ( 7 ), forming one-way valves that only allow air to pass from the inside ( 5 ) of the footwear ( 1 ) towards the chamber ( 4 ), but not in the opposite direction. Therefore, the loading of the foot ( 11 ) on the sole and the cessation of the loading give rise to a one-way circulation of air to the outside, via the chamber ( 4 ), providing ventilation to the inside ( 5 ) of the footwear ( 1 ) and therefore to the foot ( 11 ).

         3 . A self-ventilating footwear that comprises a sole with a chamber delimited on the inside of a shoe by an insole ( 3 ) with communication holes between the inside of the shoe and the chamber, and further including at least one one-way valve communicating the chamber with the exterior through which air from inside the shoe egresses, said footwear article is characterized because the holes ( 6 ) delimit the upper part of the chamber ( 4 ) in the sole and are one-way allowing the pass of air from the inside ( 5 ) of the shoe ( 1 ) to the chamber ( 4 ) in the sole, impeding the pass of air in the opposite direction by means of elastic patches ( 7 ) situated on the lower surface of the insole ( 3 ) coinciding with the area of the holes ( 6 ), said patches being partially attached along their perimeter with the insole ( 3 ). 
     
     
         4 . A self-ventilating shoe, comprising:
 A) a sole having a lower surface ( 2 ) and an insole ( 3 ) with at least one chamber thereinbetween, said insole further including at least one hole connecting said chamber with the interior of a shoe, said sole further including at least one second hole connecting said chamber to the exterior of said shoe; and   B) first one-way valve means for allowing the air inside said shoe to pass inside said chamber so that the air inside said shoe travels through said at least one first hole, said chamber, and said second hole out to the exterior in that direction only.   
     
     
         5 . The shoe set forth in  claim 4  further including:
 C) second one-way valve means for allowing the air inside said at least one chamber to pass to the exterior through said at least one second hole, said second one-way valve means coacting with said at least one second hole. 
 
     
     
         6 . The shoe set forth in  claim 5  wherein said first one-way valve means includes a flexible sheet interiorly mounted to said insole with at least one portion detached therefrom to permit the air to pass to said at least one chamber, said sheet coacting with said at least one first hole to permit the air to pass in one direction only to said at least one chamber.
