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, a resistance-adjusting element is provided at the bottom of the guidewheel. A free adjustment of the cushioning force may be achieved by the inclination of the resistance-adjusting element.
Claims4
A cushioning mechanism for a treadmill comprising:
- a) a handle frame assembly positioned at both sides of a front end of the platform frame, an electronic console being installed at a top side of the handle frame assembly while two base bars being attached to a bottom end thereof;
- b) a platform frame pivotally mounted near a bottom portion of the handle frame assembly, a continuous moving belt working in cooperation with a motor, a belt, a front roller, and a rear roller to ensure a circulating operation;
- c) a pair of ⊃-shaped rigid connection elements and a pair of pivotal rigid cushioning elements interposed between the bottom surface of both sides of the platform frame and the base bars, the pivotal rigid cushioning elements each having a guidewheel at one end thereof such that 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;
- d) a resistance-adjusting element is provided at the bottom of the guidewheel such that a free adjustment of the cushioning force may be achieved by the inclination of the resistance-adjusting element;
- and
- e) an auxiliary supporting element pivotally interposed between both sides of the platform frame and the handle frame assembly, respectively.
