<p>An elastic material inflation toy (10) includes an elongated base (11) and a generally spherical housing (13). The elongated base (11) supports a collapsible air bellows (12) and a pair of one-way check valves (50, 60) which cooperate with the air bellows (12) to produce a stream of pressurized air as the air bellows are operated. An inflation tube (30) (Fig. 3) is coupled between the air bellows pressure output and the spherical housing. The spherical housing defines an annular collar (15) which receives a pancake-like shape quantity of elastic material (30). A pivotally secured annular lock ring (16) includes a lock clap (18) for securing the lock ring upon the elastic material in a sealing attachment whereby the elastic material forms a generally air-tight seal againt 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 (39) similar to a bubble.</p> |
