Air cushion shoe device

Abstract

An air cushion shoe device installed in a shoe comprises an air cushion assembly which includes a rear pressing portion, a conduit, and a plurality of gasbags. One end of the conduit is fluidly communicated with the rear pressing portion and the other end thereof has a plurality of branches whose quantity is corresponding to the one of the gasbags. Each branch is fluidly communicated with the corresponding gasbag. A check valve is arranged between the conduit and the branches. An air hole of the conduit is located between the rear pressing portion and the check valve. When the rear pressing portion is pressed downwardly, the air received in the rear pressing portion is extruded through the conduit, the check valve, and each gasbag to each branch so that each gasbag is filled with the air to reduce the impact generated between a foot and a ground.

What is claimed is: 
     
         1 . An air cushion shoe device, installed in a shoe, comprising an air cushion assembly, wherein:
 the air cushion assembly includes a rear pressing portion, a conduit, and a plurality of gasbags, one end of the conduit is fluidly communicated with the rear pressing portion and the other end thereof has a plurality of branches whose quantity is corresponding to the one of the gasbags, each of the branches is fluidly communicated with the corresponding gasbag, a check valve is arranged between the conduit and the branches so that the air which is flowed toward the gasbags is not flowed back, an air hole is formed at the conduit and located between the rear pressing portion and the check valve for providing an outside air to enter into the conduit through the air hole and then flow toward the rear pressing portion to fill the rear pressing portion, when the rear pressing portion is forced to press downwardly, the air received in the rear pressing portion is extruded through one end of the conduit adjacent to the rear pressing portion and the check valve to the other end of the conduit opposite to the end thereof adjacent to the rear pressing portion and then flowed to each gasbag through each branch so that each gasbag is filled with the air to reduce the impact generated between a foot and a ground.   
     
     
         2 . The air cushion shoe device as claimed in  claim 1 , wherein the rear pressing portion has an air chamber, and the air chamber is received a torsion spring, two ends of the torsion spring are respectively abutted against a top side and a bottom side of the air chamber.
