Abstract
Abstract A construction toy has a first module which includes a bellows and a bulb with a tube connecting the two. The bellows includes a connector on each of its ends. Second modules each having connectors which mate with the connectors on the bellows, attached to the respective ends of the bellows. Third modules, each having an axle having wheels located thereon, are connected to the second modules utilizing mating connectors. The wheels on the third module include a ratchet mechanism allowing for rotation in only one direction. Upon each compression of the bulb, fluid pressure is transmitted to the bellows to elongate it, and in so doing, one of the third modules is moved away from the other; and upon release of the bulb, the bellows shortens bringing the other of the third modules back toward the first. The ratchet mechanisms on the third modules allow for rotation of their wheels in only a single direction such that the construction toy is progressively moved forward upon each compression and subsequent release of pressure on the bulb.
