Patent ID: 7736277

Claim:
A rocking exercising apparatus comprising: a movable unit on which a user rides; and a driving unit for causing the movable unit to perform a rocking motion, wherein the driving unit is capable of driving the movable unit to rock in forward/backward directions of the user riding on the movable unit and capable of moving the movable unit forward at a greater acceleration than when the movable unit is moved backward; wherein the driving unit includes a movable frame, a motor arranged within the movable frame, an output shaft to which torque of the motor is transferred, and a first and a second link plate for connecting the movable unit to the movable frame; wherein the output shaft has a first and a second off-centered portion lying on an external surface of the movable frame; wherein eccentric rotation of the first off-centered portion causes a front end of the movable unit to swing in the forward/backward directions through the second link plate; and wherein eccentric rotation of the second off-centered portion causes a rear end of the movable unit to swing in the forward/backward directions through the first link plate.
