Submersible toy

Claim 1

A toy article which is fitted with means to submerge the said toy article in water and to cyclically rise to the surface and then submerge again, in which said means comprise an internal chamber communicating by a vent hole to a recess open to the exterior of the said article, so that a moistened powder may be located within said chamber so as to form a gas bubble which flows through said vent into said recess to displace water out of said recess of said article and so increase the buoyancy of the article causing it to initially rise when in water, with the article then losing this increase of buoyancy after the said bubble further enlarges and detaches from the said article resulting in the article then again submerging in the water, in which said article is fitted with air suspension means to provide further buoyant effect to said article, said air suspension means serving to assist in the orientation of the article in various positions during the cycle of rising and submerging and to enable the article to oscillate with a pendulum--type motion during said cycle, where said air suspension means comprises a projection extending from the article, which projection is formed with a recess open to the exterior through an open mouth section of the projection, in which said recess and said mouth section is of a size and shape with relation to surface tension of water to prevent captive air in the said recess from escaping from the said recess while said projection is immersed in water regardless of the orientation of the said open mouth section when said projection is immersed in water, such that said air is entrapped in the said recess of the projection and acts to furnish lift to the article when the projection is so immersed.
