Discoidal amusement device

Claim 2

A discoidal toy comprising: a discoidal body having a convex top side and a concave bottom side and presenting a generally circular periphery; a cylindrical flange on the periphery of said body providing a hand grip to facilitate throwing and catching of the body, said flange having an outer surface and presenting a free edge and an opposite edge connected with said periphery of the body; a planar fin projecting outwardly from said flange at a location thereon between said free and opposite edges, said fin being annular and having flat and parallel opposite surfaces and said fin occupying a substantially horizontal plane when said bottom side of the body faces downwardly in flight; and a plurality of ribs on said flange for stabilizing said body in flight, each rib extending only below said fin and having a top end adjacent said fin and a bottom end adjacent said free edge of the flange, said ribs being spaced apart from one another substantially equidistantly on the outer surface of said flange and each rib having a generally vertical orientation when said concave side of the body faces downwardly in flight.

Claim 3

A discoidal toy as set forth in claim 1, including: a center portion of said body; and means providing an air pocket in said center portion of the body on said concave side thereof for receiving air to stabilize the body in flight.

Claim 4

A discoidal toy comprising: a discoidal body presenting a convex top side and a concave bottom side, said body having a generally circular periphery; an inverted cup projecting from said top side of the body at a substantially centered position thereon, said cup being closed at the top and open at the bottom to provide an air pocket for receiving air to stabilize said body in flight; a cylindrical flange on the periphery of said body providing a hand grip to facilitate throwing and catching of the body, said flange having an upper edge connected with said periphery and a free lower edge; an annular fin on said flange projecting outwardly therefrom at a location intermediate said upper and lower edges, said fin being a planar member with flat upper and lower surfaces parallel to one another and said fin occupying a substantially horizontal plane when said bottom side of the body faces downwardly in flight; and a plurality of ribs on said flange spaced substantially equidistantly apart in outward projection from the flange, each rib extending only from said fin to said free lower edge of the flange and not above the fin and each rib being a substantially straight member having a vertical orientation when said bottom side of the body faces downwardly in flight.

Claim 5

A discoidal toy comprising: a discoidal body presenting a convex top side and a concave bottom side, said body having a generally circular periphery; an inverted cup projecting from said top side of the body at a substantially centered position thereon, said cup being closed at the top and open at the bottom to provide an air pocket for receiving air to stabilize said body in flight; a cylindrical flange on the periphery of said body providing a hand grip to facilitate throwing and catching of the body, said flange having an upper edge connected with said periphery and a free lower edge; an annular fin on said flange projecting outwardly therefrom at a location intermediate said upper and lower edges, said fin being a planar member with flat upper and lower surfaces parallel to one another and said fin occupying a substantially horizontal plane when said bottom side of the body faces downwardly in flight; and a plurality of ribs on said flange spaced substantially equidistantly apart in outward projection from the flange, each rib extending only from said fin to said free lower edge of the flange and not above the fin and each rib being a substantially straight member having a vertical orientation when said bottom side of the body faces downwardly in flight.

Claim 6

A discoidal toy as set forth in claim 3, wherein said cup includes: a cylindrical wall projecting from said top side of the body; and a top panel extending across the top of said wall, said air pocket being presented within said wall and below said top panel.

Claim 7

A discoidal toy as set forth in claim 4, wherein said top panel has the form of a flat disk.
