Foot cushion adjustment mechanism

Abstract

A foot cushion adjustment mechanism includes a base frame having a mounting portion, a cushion member having a through hole defining a first opening and a locating member disposed in the through hole, and an adjustment device having a body portion inserted through the locating member and a first end portion inserted through the first opening and pivotally coupled to the mounting portion. Biasing the adjustment device causes the cushion member to be moved linearly relative to the base member to adjust the distance between the cushion member and the base member.

1 . A foot cushion adjustment mechanism, comprising:
 a base member having a mounting portion;   a cushion member comprising a through hole forming opposing first opening and second opening on said cushion member and a locating member disposed in said through hole; and   an adjustment device comprising a first end portion and a body portion, said body portion being inserted through said locating member, said first end portion being inserted through said first opening and pivotally coupled to said mounting portion such that biasing said adjustment device relative to said base member causes said cushion member to be moved relative to said base member to adjust the distance between said cushion member and said base member.   
     
     
         2 . The foot cushion adjustment mechanism as claimed in  claim 1 , further comprising a guide rod having one end thereof located on said locating member and an opposite end thereof inserted through said mounting portion to guide movement of said cushion member relative to said base member linearly. 
     
     
         3 . The foot cushion adjustment mechanism as claimed in  claim 1 , wherein said cushion member comprises a bottom cover covering said second opening. 
     
     
         4 . The foot cushion adjustment mechanism as claimed in  claim 1 , wherein said base member comprises a fastening member located on said mounting portion; said first end portion of said adjustment device is inserted through said mounting portion and screw-connected with said fastening member.
