Rolling board e.g. skateboard, for use in e.g. fitness training, has physical strength drive system, and perpendicular, downward directed and upward directed movements of board serve for driving and forwarding movement of board

摘要

The board has a physical strength drive system in the interior of wheels (2, 3), where the board is movable opposite to the wheels in a perpendicular direction. The perpendicular, downward directed movement and the perpendicular, upward directed movement of the board serve for driving and forwarding movement of the board. A gear wheel is connected with a shaft by a freewheel support, so that a gear rod is moved downwards. Steering mechanisms (6, 7) are attached to the board.
