Abstract
Abstract A toy of the type which is designed to be tossed, thrown, or sailed through the air by hand includes a circular, lightweight plastic or rubber disc and a plurality of surface configuration modifying structures which may be selectively secured to the disc to predictably affect the aerodynamics around the disc during flight. The disc is self-supporting and has a centrally positioned circular opening therethrough. The flight altering structures include a funnel-type device, cup-shaped device, and a pair of fins. The funnel device and the cup-shaped device are selectively attached to one side of the disc in a position centered with respect to the circular opening. The fins are attached to opposing peripheral edges of the disc.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
An aerial projectile toy comprising: (a) a substantially circular disc formed of a self-supporting, relatively soft, lightweight, moldable material; (b) a plurality of flight altering structures, each of which, when attached to said disc, provides predictable aerodynamic characteristics of the air flow path around and over said disc during flight which differ from such characteristics achieved with the other of said structures; (c) cooperative means on said disc and said flight altering structures for releasably temporarily securing selected ones of said structures at a time to said disc.
Claim 2
Dependent Claim
88 words
An aerial projectile toy comprising: (a) a substantially circular disc formed of a self-supporting, relatively soft, lightweight, moldable material; (b) a plurality of flight altering structures, each of which, when attached to said disc, provides predictable aerodynamic characteristics of the air flow path around and over said disc during flight which differ from such characteristics achieved with the other of said structures; (c) cooperative means on said disc and said flight altering structures for releasably temporarily securing selected ones of said structures at a time to said disc.
Claim 3
Dependent Claim
22 words
An aerial projectile toy according to claim 1 wherein the edge of said disc includes a means for preventing injury associated therewith.
Claim 4
Dependent Claim
20 words
An aerial projectile toy according to claim 1 wherein said disc further includes an air opening through the center thereof.
Claim 5
Dependent Claim
30 words
An aerial projectile toy according to claim 3 wherein said air opening is substantially circular with a diameter substantially equivalent to one-fourth to one-third of the diameter of said disc.
Claim 6
Dependent Claim
43 words
The toy according to claim 4 wherein one of said flight altering structures comprises a pair of arcuate fin members extending transversely to the plane of said disc and arranged diametrically opposite each other around a portion of the periphery of said disc.
Claim 7
Dependent Claim
25 words
The toy according to claim 5 wherein each of said fin members has an arcuate length of approximately one-fourth of the circumference of said disc.
Claim 8
Dependent Claim
60 words
The toy according to claim 4 wherein one of said flight altering structures comprises a cylindrical cup-shaped member attached to one of said discs, the diameter of said structure being greater than and surrounding the diameter of said opening, whereby the center of said disc and the center of said opening both lie in the axis of said cylindrical member.
Claim 9
Dependent Claim
64 words
The toy according to claim 4 wherein one of said flight altering structures comprises a conical shaped member attached to one side of said disc, the diameter of the base of said structure being greater than and surrounding the diameter of said opening, whereby the center of said disc and the center of said opening both lie along the axis of said conical member.
Claim 10
Dependent Claim
18 words
The toy according to claim 8 wherein said conical member is truncated with the smaller end being open.
