Abstract
The present invention relates to a lever type exercise apparatus comprises a base and a treadmill. The treadmill includes a platform and a continuous belt. The continuous belt extends around the platform and is rotatably supported by front and rear rollers being driven by a motor. Besides, a supporting arm is provided between the front and rear rollers of the treadmill. The bottom end thereof is pivotably connected at a first pivoting point of the base while the top end thereof is pivotably supported by a resilient cylinder which is pivotably secured to the base at a second pivoting point. After the assembly of the aforementioned components, when the front end of the treadmill is moved downward against the resistance of the resilient cylinder, the coupled supporting arm is pivoted at the first pivoting point. Thus, the top end of the supporting arm is pressed against the resilient cylinder. After the weight moves to the rear end of the treadmill, the treadmill restores itself to its original position by means of the upward resilience of the resilient cylinder. Accordingly, the treadmill moves up and down on a horizontal axis.
