Flying disk with rotatable member
First Claim
1. A flying disk device comprising a disk-like upper wall portion having a circular periphery in the form of a downwardly depending skirt, said skirt extending about a central axis which extends through the center of said disk-like upper wall portion, said upper wall and said skirt having an outer surface and an inner surface, said inner surface enclosing a hollow area to trap air therein when said flying disk is thrown with its undersurface directed somewhat downward while said disk is caused to spin about said axis, said upper wall having a central opening extending entirely through said upper wall and a rotatable member located within said opening, said member extending above said upper wall and below said upper wall into said hollow area and supported in said opening by mounting means to enable said rotatable member to spin about a chosen axis while said flying disk spins through the air.

Abstract
A flying disk which has a decorative member rotatably mounted in the top surface thereof and which is free to rotate relative to rotation of the flying disk as the flying disk is spins through the air about a central axis. In one embodiment, a hollow spherical member is mounted in a hole at the center of the flying disk member and is free to rotate about an axis which is parallel to the plane of the upper wall of the disk. Another embodiment mounts the spherical member so that it is free to rotate about the central axis of the flying disk. In another embodiment, the rotating member is a double truncated cone shape. The rotating members can have a smooth exterior surface or may have vanes projecting therefrom and/or openings, e.g., elongated slits or circular holes, therein, to impart spin to the rotating members during flight of the flying disk.
