PURPOSE:To cause the generation of energy by allowing a treading board to move up and down every time a car passes. CONSTITUTION:When a car B rides on a treading board 2, the board 2 is pushed down to stop contactedly on and parallel to a base plate 1. when the car B has passed through the treading board 2, it is pushed up to form again a triangular space 5. If the car B pushes down the treading board 2, a crank 6 moves downward to turn a gear 10 by a ratchet 9 of a floating rod 8, and a generator 14 is turned by means of a belt 15 of a wheel 11. |
