Abstract:
1. A treadmill having an integrated folding mechanism, the treadmill comprising: a platform frame adapted to rest on a horizontal support surface; a transmission motor disposed at one side of the platform frame for driving a continuous moving belt into rotation by use of a transmission belt; a front roller; a rear roller; a lifting motor being employed to move an adjusting support upward and downward for adjusting the incline angle of the platform frame relative to said support surface; two connection pins being disposed on the platform frame to extend laterally from one side of the platform frame to the other side of the platform frame respectively, for pivotally coupling a handrail assembly and a rear support assembly, respectively to the platform frame; first and second strengthening bars disposed on the platform frame to extend laterally from one side of the platform frame to the other side of the platform frame; a slide pusher interposed between the connecting pins and the second strengthening bar and disposed on the platform frame; a slide rail, supported by the first and second strengthening bars, provides sliding surfaces for said slide pusher, wherein one end of the slide pusher is pivotally connected to said rear support assembly; a third strengthening bar, disposed on the platform frame, is pivotally coupled with a pneumatic cylinder at the bottom thereof in such a way that the other end of the pneumatic cylinder directly rests against a tail of the slide pusher; a connecting rod interconnected between the rear support assembly and the handrail assembly such that the handrail assembly can synchronously move with the platform frame between a folded and an extended position; and an engaging mechanism disposed at the bottom of a fourth strengthening bar, that is connected to the platform frame, wherein the engaging mechanism can be actuated to apply 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 into a horizontal application position.
