Abstract
A flying ring having a circular inner edge 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 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.
Claims19
A flying ring comprising an annular disk having inner and outer continuous coaxial edges, said disk, transversely between said inner and outer edges, being arced to define an aerodynamic configuration with a transversely convex upper surface and a transversely concave lower surface, said aerodynamic configuration being continuous about said annular disk, four lobes extending beyond said outer edge at equally spaced positions thereabout, each lobe having an arcuate outer edge and being circumferentially elongate, each lobe having a maximum radial width outward of said outer edge at a central cusp and tapering to each side thereof to minimum widths at the opposed ends thereof, said ends being in substantial alignment with spaced adjacent ends of adjacent lobes and in substantial alignment with said disk outer edge, said lobe outer edges and said disk outer edge between said lobes defining an outer periphery of a generally squared circle configuration.
A flying ring comprising an annular disk defined by an inner circular periphery and an outer coaxial curvilinear periphery, said disk being transversely arcuate outward of said inner periphery annularly about said disk to define an aerodynamic configuration to said disk with a transversely convex outer surface and a transversely concave inner surface, said disk outer periphery having first and second equal length maximum diameters at 90° to each other, and first and second equal length minimum diameters at 90° to each other and at 45° to said maximum diameters, the length of said minimum diameters being less than the length of said maximum diameters with the outer periphery of said disk being of a generally square configuration with rounded corner portions and a continuous curvature along the length thereof.
An aerodynamic flying ring having an annular body transversely arcing in cross section and including a circular inner edge and a coaxial substantially curvilinear outer periphery, said outer periphery being of a generally square configuration with equal length flattened sides and four rounded corners, said rounded corners defining hand grip areas.
