ABSTRACT:
An electric treadmill with a folding mechanism by use of a swivel piece includes a handrail frame mounted at both sides of the front end of the base frame. Moreover, an axle is positioned near the middle portion of the bottom of the base frame for pivotally connecting with a swivel piece at both sides thereof, respectively. A pull rod is pivotally interposed between the swivel piece and the handrail frame. Moreover, a rear support frame having ground-touching rollers is pivotally connected to the axle such that the rear support frame is constantly supported by a telescopic support element. When the base frame is folded upward, the rear support frame is pushed forward by an action portion of the telescopic support element. Meanwhile, the ground-touching rollers are always in contact with the ground in a supporting position. In this way, the base frame can be brought in a stable folded-up position.
