ABSTRACT:
A flying disk toy comprising a substantially planar disk configured to rotate about a central axis in sustained flight and a centrifugally activated sound generator associated with the disk is disclosed. The disk includes a cylindrical wall perpendicularly projecting from the plane of the disk and which is centrally disposed on the disk relative to its central axis. The centrifugally activated sound generator comprises two diametrically opposed centrifugal switches in series connection, each comprising a radially extending, axially inclined ramp, a pair of electrical contacts symmetrically disposed on opposite sides of the ramp in spaced apart relationship and an electrically conductive weight movably supported on the ramp. The weight has a diameter greater than the minimum spacing of the electrical contacts and centrifugal force resulting from the rotation of the disk in flight causes the weight to displace into both electrical contacts, thereby establishing an electrical closed circuit and energizing the sound generator.
