Patent attributes
A curved treadmill has a frame assembly, a handrail assembly, and a belt assembly. The frame assembly has a support frame, two arced guide tracks, two cushions, multiple guide wheels, and multiple positioning wheels. Each arced guide track is concaved downward. The cushions are mounted on the arced guide tracks. The guide wheels are mounted on the support frame. The positioning wheels are mounted between two ends of the support frame. The belt assembly includes two connection belts and multiple pedals. The connection belts are wrapped around the guide wheels, and one side of each connection belt abuts the positioning wheels. The pedals are mounted on the connection belts and optionally abut the cushions. Therefore, with the cushions, impacts may be absorbed and noises may be reduced. Besides, by abutting the positioning wheels, the connection belt may not be distorted sideward, and the noises are reduced further.
