Patent ID: 7785236

Claim:
An exerciser having magnets adjusting device, comprising: a frame assembly allowing the exerciser to be firmly placed on a horizontal surface; a flywheel, with a front shaft, rotatably mounted on the frame assembly; a driving assembly allowing reciprocal force to be applied by users; a power transmission mechanism provided to transfer the force from the driving assembly to the flywheel, and allowing the flywheel to be rotated corresponding to the frame assembly; and a magnets adjusting device having at least a magnetic unit which will reciprocate with the rotating flywheel to generate magnetic resistance, and comprising: a guiding rail fixed on the frame assembly, whose top side and bottom side respectively pivotally mounted with a plurality of first rollers having horizontal axis, and respectively pivotally mounted with a plurality of second rollers having vertical axis; a sliding unit with the at least a magnetic units fixed thereon, mounted on the guiding rail and being able to move along the guiding rail; the sliding unit having a base plate whose two edges extend to a bended side plate, the two side plates respectively corresponding to the top side and bottom side of the guiding rail, each side plate also extending to a bended hook plate parallel to the base plate, the rollers on the top side and the bottom side of the guiding rail respectively located between their corresponding hook plate and the base plate, and the rollers with horizontal axis contacting with the side plate and the rollers with vertical axis contacting with the hook plate; and a control mechanism provided to control the reciprocated movement of the sliding unit along the guiding rail and to control the magnetic units to be linearly moved close to or away from the axis of the flywheel.
