Low-loaded exercise treadmill

Abstract

The present invention relates to a low-loaded exercise treadmill comprises a base and a frame. The frame includes a platform and a continuous belt which extends around the platform and is rotatably supported by front and rear rollers by mean of being driven by a motor. The rear end of the frame is fitted with a coupling piece which is pivotably connected to the base while the front end thereof includes a movable supporting bar which is attached to a resilient member at the bottom end thereof. Moreover, the resilient member is located at a proper position of the base. Based on the assembly of the aforementioned members, when the front end of the frame is pressed, the frame is downwardly inclined by means of the simultaneous displacement of the supporting bar. After the loading is reduced gradually, the frame restores itself by means of the extending force of the resilient member so that the frame can make ups and downs movement repetitively.

What is claimed is:  
     
         1 . A low-loaded exercise treadmill comprising: 
 a base; and    a frame having a platform and a continuous belt, said continuous belt extending around the platform and being rotatably supported by front and rear rollers by mean of being driven by a motor;    wherein the rear end of said frame is fitted with a coupling piece which is pivotably connected to said base while the front end thereof includes a movable supporting bar which is attached to a resilient member at the bottom end thereof, and said resilient member is located at a proper position of said base; and wherein, based on the assembly of the aforementioned members, when the front end of said frame is pressed, said frame is downwardly inclined by means of the simultaneous displacement of said supporting bar, and after the loading is reduced gradually, said frame restores itself by means of the extending force of said resilient member so that said frame can make an ups and downs movement repetitively.
