Abstract

An integrated folding mechanism of a treadmill having a slide pusher supported by a pneumatic cylinder at the bottom of a platform frame thereof. In this way, the rear support may be pushed upward to bring the platform frame in a vertical stable folding position or in a flat ground-touching position when the platform frame is moved upward and downward. Meanwhile, a coupling rod is pivotally interposed between the rear support and an L-shaped handrail assembly. Under the action of an elastic element, the handrail assembly is movable with the platform frame for creating a synchronic folding and extending action.

Claims

1. An integrated folding mechanism 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 rail, on which a slipper moves, is interposed between a first and a second strengthening bar;

wherein a slide pusher is pivotally attached to the bottom of the slipper while the other end of the slide pusher is pivotally connected to the rear support;

wherein a pneumatic cylinder is pivotally coupled to the bottom of a third strengthening bar of the platform frame while the other end of the pneumatic cylinder is pivotally attached to a central crossbar of the slide pusher; and

wherein a coupling rod is pivotally interposed between the rear support and the handrail assembly. Under the action of an elastic element, the handrail assembly is movable with the platform frame for creating a synchronic folding and extending action.

2. An integrated folding mechanism 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 rail, on which a slipper moves, is interposed between a first and a second strengthening bar;

wherein a slide pusher is pivotally attached to the bottom of the slipper while the other end of the slide pusher is pivotally connected to the rear support;

wherein a pneumatic cylinder is pivotally coupled to the bottom of a third strengthening bar of the platform frame while the other end of the pneumatic cylinder is pivotally attached to the rear end of the slide pusher; and

wherein a coupling rod is pivotally interposed between the rear support and the handrail assembly. Under the action of an elastic element, the handrail assembly is movable with the platform frame for creating a synchronic folding and extending action.
