Abstract
A cushioning mechanism for a treadmill having a pair of ⊃-shaped rigid connection elements and a pair of pivotal rigid cushioning elements that are interposed between the bottom surface of both sides of the platform frame and the base bars. The pivotal rigid cushioning element includes a guidewheel at one end thereof. In this way, the guidewheel is movable on the surface of the base bar when the platform frame is moved up and down by the external forces applied to it. Accordingly, the cushioning and restoring effects can be achieved. Moreover, an auxiliary supporting element is pivotally interposed between both sides of the platform frame and the handle frame assembly, respectively. As a result, a complete cushioning and restoring effect can be ensured.
