Abstract
Abstract An aerodynamic toy is provided with a circular central portion having a center surrounded by a substantially flat circular surface, a rim circumscribing the circular central portion terminating in a given plane, a surface of curvature extending from the flat circular surface and curving downwardly to the rim to form an outer convex surface and an inner concave surface and a lip concentric with the rim and extending from the inner concave surface and terminating before the given plane.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
An aerodynamic toy comprising an integral body having: a. a circular central portion having a center surrounded by a substantially flat circular surface; b. a rim circumscribing the circular central portion terminating in a given plane; c. a surface of curvature extending from the flat circular surface and curving downwardly to the rim to form an outer convex surface and an inner concave surface; and d. a lip concentric with said rim and extending from the inner concave surface and terminating before the given plane.
Claim 2
Dependent Claim
85 words
An aerodynamic toy comprising an integral body having: a. a circular central portion having a center surrounded by a substantially flat circular surface; b. a rim circumscribing the circular central portion terminating in a given plane; c. a surface of curvature extending from the flat circular surface and curving downwardly to the rim to form an outer convex surface and an inner concave surface; and d. a lip concentric with said rim and extending from the inner concave surface and terminating before the given plane.
Claim 3
Dependent Claim
27 words
The aerodynamic toy according to claim 1, wherein the lip is spaced from the rim a distance effective to prevent the insertion of an adult finger therebetween.
Claim 4
Dependent Claim
14 words
The aerodynamic toy according to claim 2, wherein the lip is cylindrical in configuration.
Claim 5
Dependent Claim
25 words
The aerodynamic toy according to claim 2, wherein the lip has an arcuate cross section with a concave inner surface and a convex outer surface.
Claim 6
Dependent Claim
42 words
The aerodynamic toy according to claim 1, wherein the integral body comprises a foam and the lip is spaced from the rim a distance sufficient to permit the insertion of an adult finger therebetween and wherein the lip is cylindrical in configuration.
Claim 7
Dependent Claim
34 words
The aerodynamic toy according to claim 1, wherein the rim has an outer convex surface and wherein the flat circular surface, the surface of curvature and outer convex surface of the rim are smooth.
Claim 8
Dependent Claim
39 words
The aerodynamic toy according to claim 1, wherein the rim has an outer convex surface and wherein the connections of the outer convex surface of the rim, the flat circular surface and the surface of curvature have no discontinuities.
Claim 9
Dependent Claim
39 words
The aerodynamic toy according to claim 6, wherein the rim has an outer convex surface and wherein the connections of the outer convex surface of the rim, the flat circular surface and the surface of curvature have no discontinuities.
