Abstract: A domino toppling toy is provided which is capable of toppling a plurality of domino pieces in domino trains located at different vertical elevations. The last domino piece in a lower domino train actuates an actuation lever and hence a locking lever. The locking lever then releases a lock of an upwardly energized lifter carriage movement. An intermediate domino piece disposed in the lifter carriage in an upright position topples down outwardly from the lifter carriage on to the first domino piece in an upper domino train, when the lifter carriage is stopped by a stopper plate for further upward movement, thus enabling to drive the higher domino train by the toppling force of the lower domino train.

Abstract: There is provided a domino toppling toy which includes a movable member capable of moving toward and away with respect to the first domino piece in the domino train. The movement can be held at the position away from the first domino in a normal position and can push the first domino piece as operated to apply a toppling force thereto.
