Abstract
Abstract An aerodynamic toy having a central portion of circular configuration and a peripherally connecting rim portion. The central portion has a flat top surface while the connected rim portion has a rounded surface. The flat top surface of the central portion is contiguous with the rounded edge portion. The toy is constructed of a soft, flexible, foam material of substantially uniform density.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
An aerodynamic toy comprising: a. a central portion of circular configuration having a substantially flat top surface and a thickness of less than the diameter of said central portion, said central portion having a lower concave surface; b. a rim portion integrally formed with said circular central portion, said rim portion having a thickness greater than the thickness of said central portion, said rim portion having a smooth continuous, rounded outer surface which extends to said flat top surface of said central portion, said outer surface of said rim portion and said flat top surface of said central portion forming an uninterrupted surface, said central portion and said rim portion being constructed of a soft, flexible, foam material of uniform density.
Claim 2
Dependent Claim
121 words
An aerodynamic toy comprising: a. a central portion of circular configuration having a substantially flat top surface and a thickness of less than the diameter of said central portion, said central portion having a lower concave surface; b. a rim portion integrally formed with said circular central portion, said rim portion having a thickness greater than the thickness of said central portion, said rim portion having a smooth continuous, rounded outer surface which extends to said flat top surface of said central portion, said outer surface of said rim portion and said flat top surface of said central portion forming an uninterrupted surface, said central portion and said rim portion being constructed of a soft, flexible, foam material of uniform density.
