Abstract
A hand propelled circular air glider or flying saucer type aerodynamic toy. The toy includes a solid upper disc portion and a concentric, substantially larger lower annular disc portion having an aperture therein approximately equal to the diameter of the upper disc portion. The upper disc portion and lower annular portion are disposed generally parallel and are connected together by a plurality of radially directed, generally trapezoidal, evenly spaced fins. A depending, short cylindrical flange circumscribes the outer perimeter of the lower annular portion to stabilize the flight of the toy as it precesses through a gaseous medium.
Claims8
An aerodynamic toy, comprising:
- a generally circular upper disc portion;
- a lower annular ring portion concentric with said upper disc portion, with a central aperture therethrough;
- and
- angularly spaced support means connecting said upper disc portion and said lower ring portion in a parallel, spaced relation providing air passage means through said aperture and the spaced support means and between the upper disc portion and lower annular ring portion, and whereby precession of the toy through the air will impart lift to the toy.
An aerodynamic toy, comprising:
- a generally circular upper disc portion;
- a lower annular ring portion concentric with said upper disc portion and having a diameter substantially larger than said upper disc portion;
- a central circular aperture in said lower annular ring portion, having a diameter approximately equal to the diameter of said upper disc portion;
- a generally perpendicular, depending flange about the periphery of said lower annular ring portion;
- and
- a plurality of equally spaced, radially directed fins connected between the upper disc portion and the lower disc portion to maintain said discs in a parallel, spaced relation providing air passage means through said aperture and the spaced support means and between the upper disc portion and lower annular ring portion, and whereby precession of the toy through the air will impart lift to the toy.
