Abstract:
1. A folding apparatus of a treadmill having a platform frame with a transmission motor at one side thereof for driving a continuous moving belt into rotation by use of a transmission belt, a front roller, and a rear roller, a lifting motor being employed to move an adjusting support upward and downward for adjusting the supporting angle of the platform frame, two connection pins being disposed at both sides of the platform frame, respectively, for pivotally coupling a handrail assembly and a rear support, respectively, wherein a slide pusher, to which a pneumatic cylinder applies a pushing force, is interposed between a first and a second strengthening bar while the other end of the slide pusher is pivotally connected to the rear support, whereupon a coupling rod is interposed between the rear support and the handrail assembly; accordingly, the handrail assembly may be folded up by the coupling rod in cooperation with a crossbar; and wherein an engaging mechanism is disposed at the bottom of a strengthening bar of the platform frame such that the engaging mechanism applies a proper engaging force to a positioning plate fixed at the bottom of the internal side of the handrail assembly when the platform frame is brought in a horizontal application position, whereby any unexpected false pushing action is avoided when the lifting motor and the adjusting support are employed to adjust the exercise slope.
