Platform for supporting conveyor belt of treadmill

Abstract

A platform for supporting a conveyor belt of a treadmill includes a wooden plate, a reinforcement plate above the wooden plate, and a shock-absorbing plate sandwiched between the wooden plate and the reinforcement plate. The shock-absorbing plate has a surface facing the wooden plate base, and a plurality of cushions protruding from the surface and stopping against the wooden plate for providing good elastic support force and cushion effect.

What is claimed is: 
     
         1 . A platform for supporting a conveyor belt of a treadmill, the platform comprising:
 a wooden plate;   a reinforcement plate above the wooden plate; and   a shock-absorbing plate sandwiched between the wooden plate and the reinforcement plate and provided with a surface facing the wooden plate base, and a plurality of cushions protruding from the surface and stopping against the wooden plate.   
     
     
         2 . The platform as claimed in  claim 1 , wherein the cushions each are an inverted truncated cone having a relatively wide top end connected with the surface of the shock-absorbing plate, and a relatively narrow bottom end stopped at the wooden plate. 
     
     
         3 . The platform as claimed in  claim 1 , wherein the cushions are spacedly arranged in a matrix in rows and columns. 
     
     
         4 . The platform as claimed in  claim 3 , wherein an interval between each two of the rows of the matrix is equal to an interval between each two of the columns of the matrix. 
     
     
         5 . The platform as claimed in clam  3 , wherein each two of the rows of the matrix have an equal interval and the columns that are arranged at a front portion of the shock-absorbing plate have an interval smaller than that of the columns that are arranged at a rear portion of the shock-absorbing plate.
