Shock absorbing shoe

Abstract

The present invention discloses a shock absorbing shoe. The shock absorbing shoe comprises: an upper member which wraps and protects the instep and ankle; a cushion member which is sutured to the upper member, improves a frictional force between the sole of a foot and the ground, and consists of a forefoot portion and a heel portion each having a recess of a predetermined depth; a buffering unit which is arranged-in the respective recesses of the forefoot and heel portions of the cushion member for absorbing shocks while the wearer is walking or running; an air pumping unit which is arranged in the recess of the heel portion to perform an auxiliary buffering action and which supplies air onto the forefoot portion; and a bottom sole which is mounted on the upper part of the cushion member and to which the foot sole of the user is tightly attached. By this, a mutual complementary buffering effect is exhibited by the coil springs and the auxiliary buffering body and so on, thus doubling the shock absorbing effect. Therefore, there is no strain given to the knee or joints of the user, so the convenience of use and marketability can be enhanced.

What is claimed is:  
     
         1 . A shock absorbing shoe, comprising: 
 an upper member which wraps and protects the instep and ankle;    a cushion member which is sutured to the upper member, improves a frictional force between the sole of a foot and the ground, and consists of a forefoot portion and a heel portion each having a recess of a predetermined depth;    a buffering unit which is arranged in the respective recesses of the forefoot and heel portions of the cushion member for absorbing shocks while the wearer is walking or running;    an air pumping unit which is arranged in the recess of the heel portion to perform an auxiliary buffering action and which supplies air onto the forefoot portion; and    a bottom sole which is mounted on the upper part of the cushion member and to which the foot sole of the user is tightly attached.    
     
     
         2 . The shoe of  claim 1 , wherein the buffering unit comprises: 
 upper and lower caps which are symmetrical to each other and has a plurality of annular flanges projected, the annular flanges having insert grooves on the inside surfaces facing each other; and    coil springs which integrally connect the upper and lower caps with both opposite ends being forcedly inserted into annular flange insert grooves of the upper and lower caps and which have a predetermined elastic force.    
     
     
         3 . The shoe of  claim 1 , wherein the air pumping unit comprises: 
 an air pump which is arranged in the recess of the heel portion and compress air by a shock from the upside; and    an air supply pipe which is extended from one side of the air pump to penetrate the recess of the forefoot portion and supplies the compressed air from the air pump to the recess of the forefoot portion.    
     
     
         4 . The shoe of  claim 3 , wherein a plurality of through holes are formed on the forefoot portion of the bottom sole.  
     
     
         5 . The shoe of  claim 3 , wherein the air supply pipe is formed by forming a guide groove on the cushion member to a predetermined depth.  
     
     
         6 . The shoe of  claim 1 , wherein a projecting cushion relatively projecting toward the heel of the wearer is formed on the heel portion the cushion member.  
     
     
         7 . A shock absorbing shoe, comprising: 
 upper and lower caps which are symmetrical to each other and have a plurality of annular flanges projected, the annular flanges having insert grooves on the inside surfaces facing each other; and    coil springs which integrally connects the upper and lower caps with both opposite ends being forcedly inserted into annular flange insert grooves of the upper and lower caps and have a predetermined elastic force.    
     
     
         8 . The shoe of  claim 7 , wherein the coil springs have a rectangular cross sectional shape.  
     
     
         9 . The shoe of  claim 7 , wherein an auxiliary buffering body is additionally sandwiched on a space region between the upper and lower caps so that it can be mounted adjacent to each of the coil springs.  
     
     
         10 . The shoe of  claim 9 , wherein the auxiliary buffering body is formed of rubber.  
     
     
         11 . A shock absorbing shoe, which has a sole attached to the bottom portion of the shoe for protecting the foot sole and forming a friction with the ground, comprising: 
 a cushion member which has an upper of the shoe attached thereto to form the shape of the shoe and a recess of a predetermined shape provided on the bottom surface;    a friction member which is attached to the bottom surface of the cushion member for forming a friction with the ground; and    a shock absorbing member which is arranged in the recess and has a predetermined recess formed between the cushion member and the friction member and several rectangular cross sectional coil springs elastically mounted between fixed caps.    
     
     
         12 . The shoe of  claim 11 , wherein the shock absorbing member is formed by mounting fixed caps on upper and lower parts of the rectangular cross sectional coil springs, passing a wire through the center of the fixed caps at the upper and lower parts, with both ends being fixed to the fixed caps, and locating fixed plates having the same shape as the recess on the upper and lower parts of the fixed caps.  
     
     
         13 . The shoe of  claim 11 , wherein the recess to be formed on the bottom surface of the cushion member is formed on the heel portion and a transparent window portion through which the rectangular cross sectional coil springs can be seen is formed on a side face of the recess.  
     
     
         14 . The shoe of  claim 11 , wherein the recess to be formed on the cushion member is formed on the heel portion and the forefoot portion.  
     
     
         15 . The shoe of  claim 11 , wherein the rectangular cross sectional coil springs provided at the shock absorbing member are firstly compressed when mounted between the fixed caps, and the elastic force applied to the heel portion is larger than the one applied to the forefoot portion.
