Treadmill

Abstract

A treadmill includes a bottom bracket, a movable unit, and a treadmill platform. The bottom bracket is assembled with a standing bracket extending upward, and the standing bracket is assembled with a handlebar. The moveable unit is movably connected on the standing bracket. A driving unit is assembled with the bottom bracket for driving the movable unit to slide along an extension direction of the standing bracket. The front end of the treadmill platform is pivotally connected on the movable unit, so that the front end is moved along with the movement of the movable unit at the same time, thereby changing the slope of the treadmill platform.

What is claimed is: 
     
         1 . A treadmill, comprising:
 a bottom bracket assembled with a standing bracket extending upward, and the standing bracket being assembled with a handlebar;   a movable unit movably connected on the standing bracket, wherein the bottom bracket is assembled with a driving unit for driving the movable unit to slide along an extension direction of the standing bracket; and   a treadmill platform having a front end and a rear end, wherein the front end is pivotally connected on the movable unit, so that the front end is moved along with a movement of the movable unit at the same time.   
     
     
         2 . The treadmill according to  claim 1 , wherein the movable unit is slidable along the standing bracket to a position higher and lower than a height of the rear end. 
     
     
         3 . The treadmill according to  claim 1 , wherein the movable unit is a sleeve fitted over an outer periphery of the standing bracket. 
     
     
         4 . The treadmill according to  claim 1 , wherein the standing bracket is assembled with a rail extending along the extension direction of the standing bracket, and the movable unit is a slider slidably assembled on the rail. 
     
     
         5 . The treadmill according to  claim 1 , wherein a bottom end of the standing bracket is pivotally connected to the bottom bracket so as to be swung relative to the bottom bracket.
