Title:
AERODYNAMIC FLYING RING
Document Type and Number:
Japanese Patent JP2003265664
Kind Code:
A
Abstract:

To provide an aerodynamic flying ring, which is strongly spinned, actually easily gripped and thrown to perform a straight and controlled throw, and especially advantageous in terms of human engineering.

The flying ring (10) includes a circular inner edge (12), and an outer periphery configured as a rounded square (14). The main body of the ring, outward of the inner circular edge, is transversely arced along the full annular length thereof, providing a convex upper surface and a concave lower surface with the lower surface forming a continuous recess about the body. Four equally spaced separate rounded lobes or projection parts (26) provided about the disk each include a lower surface with an arcuate elongate aerodynamic recess (34) therein outward of and independent of the body recess providing additional lift in response to the motion of the ring when propelled.
