ABSTRACT:
The preferred embodiment as disclosed in this invention refers to a control device that provides adjustment to the height of a treadmill runner frame. It primarily entails have a through hole, a front lever hole and another anchoring hole for the extended axle furnished along the two connecting pieces according to designated high/low positions respectively in relation to its front and rear configuration. In which, the locations of frame through holes and the front lever through holes are individually connected to the rear of the connecting pieces toward the lower parts. As a result, the said connecting pieces are then connected to the two front sides of the frame through holes and fastened with screws. Then on, the front support lever through holes are fasten to the front lever holes with screw connection. Thereafter, an extended axial bar is inserted through the extended axial through holes between the two connecting pieces, and finished off by installing an adjustment mechanism on top of the said extended axial bar. And the said adjustment mechanism's operating end is so positioned that it extends out from the front side of the runner frame, and fixed in place at the position bump of the front support lever. As a result, when the operating piece of the adjustment mechanism is maneuvered by dragging the threaded lever towards the front of rear, it triggers the extended axial bar to generate a synchronized movement, at this time the connecting pieces will rotate around the front support lever's through holes as the center to produce rotational movement, which will then shift along the position holes along the through holes of the frame to move up and down to achieve modifying the support angles.
