1. A folding mechanism for a handrail frame assembly 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, a through pivot being disposed at the bottom of the platform frame for a pivotal connection with the handrail frame assembly,wherein a coupling cross shaft with a rotational disc at each side thereof is employed to pivotally coupled to the hollow handrail frame assembly, and wherein a pull rod is received within the handrail frame assembly;

  • whereby two handles and a console support at the top end of the handrail frame assembly move by use of the corresponding action of the pull rod toward each other or away from each other in position when the handrail frame assembly is folded in a storage position or moved in an upright position,wherein a pneumatic cylinder is pivotally mounted on a strengthening bar in the middle of the platform frame while the other end of the pneumatic cylinder is connected with a push element configured to constantly apply both a pushing force to assist a manual folding process and continued pressure on the coupling cross shaft after folding to keep the handrail frame assembly from unwanted unfolding.
