Abstract

An aerodynamic toy of a generally flat circular configuration adapted to glide through the air when thrown with a rotational movement imparted thereto, the configuration producing an aerodynamic lift, and the material of the toy consisting of a flexible, resilient polyurethane foam wherein the foam density in the central regions is slightly greater than at the peripheral region, and a recess is formed on the underside. The configuration of the body in conjunction with the recess producing aerodynamic lift, and the body material permitting the toy to be used indoors.

Claims

1. An aerodynamic toy comprising, in combination, a body formed of a soft, flexible, homogeneous, thermoplastic, resilient, foam material having a circular peripheral edge, a central region having a higher density than the density at said edge, a substantially flat upper surface and a lower surface, said peripheral edge comprising a convex surface formed of said foam material defining an aerodynamic lift surface, said lower surface being recessed throughout said central region defining a rim of foam material adjacent said peripheral edge having a body thickness between said upper and lower surfaces greater than at said central region and a foam material density less than at said central region, the density of said foam material within said central region between the recess defined in said lower surface and said upper surface being greater than the density of said foam material within said rim, and an annular heat formed high density bead defined on said peripheral edge of said foam material, said bead maintaining the foam material adjacent said peripheral edge under compression to define said convex surface.

2. In an aerodynamic toy as in claim 1 wherein said bead is defined on said peripheral edge substantially equidistant from said body upper and lower surfaces and at the location on said body defining the greatest diametrical dimension.
