Abstract
A treadmill is described herein that utilizes a simple mechanism that absorbs impacts delivered to the treadmill by a user during use. The treadmill includes a frame for supporting an endless belt. A forward structure supports a first end of the frame. A pivoting structure supports and the second end of the frame and provides impact absorption. The pivoting structure includes a pivot arm that is pivotally affixed to an underside of the frame. A roller is mounted on a roller axle proximate the free end of the pivot arm. A spring is provided that has a first end in communication with the frame and has a second end in communication with the pivot arm for biasing the pivot arm away from the frame. Preferably, the spring surrounds a limiter that limits the maximum amount of travel that the pivot arm can extend away from the frame.
