Abstract
An elastic material inflation toy includes an elongated base and a generally spherical housing. The elongated base supports a collapsible air bellows and a pair of one-way check valves which cooperate with the air bellows to produce a stream of pressurized air as the air bellows are operated. An inflation tube is coupled between the air bellows pressure output and the spherical housing. The spherical housing defines an annular collar which receives a pancake-like shape quantity of elastic material. A pivotally secured annular lock ring includes a lock clasp for securing the lock ring upon the elastic material in a sealing attachment whereby the elastic material forms a generally air-tight seal against the spherical housing collar. As the air bellows are operated, the pressure within the spherical housing inflates the portion of the elastic material spanning the collar into a spherical expansion similar to a bubble. The inflation process may be continued until the spherical expansion of elastic material bursts.
