Abstract
An essentially non-compressible cartesian toy submarine is provided which, when submersed in a liquid confined within a pressurized vessel, has the ability to ascend, descend and travel in a lateral plane in response to minor variations in pressure imposed within the vessel. The toy is comprised of a hull having a streamlined bow and a vertically tapered stern. An air-holding chamber, centrally positioned on the upper portion of the hull, has an aperture in its lowermost portion located within the hull. A channel extends through the rear portion of the hull, communicating with said air-holding chamber and the exterior of said hull. The channel is preferably straight and angled downwardly and sidewardly with respect to the longitudinal axis of the hull.
Claims5
A toy submarine comprising an elongated cylindrical hull having a bow configuration streamlined to minimize resistance to forward motion through a liquid medium and a stern portion which tapers to a vertically disposed terminus as a result of the convergence of two essentially vertically disposed opposing surfaces, a rigid air-holding chamber substantially centrally positioned on the upper portion of said hull, said chamber having an aperture in a lower portion thereof located within said hull, and a straight cylindrical channel within said hull communicating with said chamber and emerging from one of said opposing surfaces, said channel having a downwardly angled orientation in going from said chamber to said surface.
