发明名称 Aerodynamic flying ring
摘要 A flying ring (10) having a circular inner edge (12) and a outer periphery configured as a rounded square. 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 (26) provided about the disk each include a lower surface with an arcuate elongate aerodynamic recess therein outward of and independent of the body recess providing additional lift in response to the motion of the ring when propelled. <IMAGE>
