Air cushion

Abstract

An air cushion has a body and a supporting cushion. The supporting cushion is mounted inside of the body and has multiple hexagon-shaped holes. The holes are formed through the supporting cushion and construct as a hive structure. The hive structure is able to provide an excellent supporting effect to make a person's feet comfortable.

1 . An air cushion for a shoe comprising 
 a body being hollow and flat and having 
 an air chamber defined inside of the body;  
 a side;  
 an air-entering device mounted at the side of the body; and  
 an air-discharging device mounted at the side of the body;  
   a supporting cushion being a resilient block and having multiple hexagon-shaped holes formed through the supporting cushion and constructing as a hive structure.    
     
     
         2 . The air cushion for a shoe as claimed in  claim 1 , wherein the air-entering device has 
 a pipe having a distal opening and a proximal opening mounted at the side of the body and communicating with the air chamber; and    a check valve mounted at the distal end of the pipe to allow air enter the air chamber;    the air-discharging device has    a pipe having a distal opening and a proximal opening mounted at the side of the body and communicating with the air room of the body; and    a check valve mounted at the distal end of the pipe to allow air exhaust out of the air chamber.
