ABSTRACT:
A fold-up mechanism for an electric treadmill having a single lifting motor for bringing a main frame thereof in a tilt and a fold-up position. The lifting motor and a transmission spindle are positioned between both inverted T-bases. A slide tube with a female threaded hole is threadedly mounted on the transmission spindle. An opposing end of the slide tube is pivotally coupled to a lifting rod. Meanwhile, a front cross bar is attached to an opposing end of the lifting rod. Two handrails are extended upwardly from both side of the front cross bar. Moreover, one end of the main frame is pivotally attached to middle bars of the inverted T-bases while a telescopic unit and a pull rod are pivotally coupled at a first end thereof to the bottom end of the main frame as well as at a second end thereof to slide tube and the lifting rod, respectively. In this way, when the lifting motor comes into operation to impart motion to the transmission spindle for an in-place rotation, the slide tube undergoes a reciprocating displacement, thereby bringing the main frame in a tilted and a fold-up position.
