Abstract
Abstract An aerodynamic toy is provided for use in throwing games. The toy is shaped somewhat like a saucer and its body is provided on its convex sides with radial elevations. These provide discontinuities to the flow of air so that in use the air flow over the convex surface of the aerodynamic toy is disrupted thereby creating a turbulent air layer over the moving surface and reducing aerodynamic drag. An openable central compartment on the concave side may be used to contain batteries and a switch to power lights. The latter are supported by clips near the rim of the saucer.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
181 words
An aerodynamic toy comprising a rotatable free flight body of generally circular configuration and having a convex upper surface and a concave bottom surface comprising a geometrically centrally disposed cylindrical shaped first body portion of predetermined uniform length having an upper end and a lower end, a flat surface integral with and enclosing the cylindrical body portion at its upper end, a second body portion concentric with said first body portion having an upper convex side and a lower concave side, said second body portion being integral with and extending outwardly from the cylindrical body portion at its open end, a rim portion integral with and defining the circumferential perimeter of the second body portion, said rim portion having the shape of a parabola forming a smooth curve with and being an extension of the second body portion and opening toward the center of the aerodynamic toy, and a plurality of elevations extending rectilinearly along said upper convex side and radially outwardly from the said first body portion to points adjacent said rim and being integral with said second body portion.
Claim 2
Dependent Claim
181 words
An aerodynamic toy comprising a rotatable free flight body of generally circular configuration and having a convex upper surface and a concave bottom surface comprising a geometrically centrally disposed cylindrical shaped first body portion of predetermined uniform length having an upper end and a lower end, a flat surface integral with and enclosing the cylindrical body portion at its upper end, a second body portion concentric with said first body portion having an upper convex side and a lower concave side, said second body portion being integral with and extending outwardly from the cylindrical body portion at its open end, a rim portion integral with and defining the circumferential perimeter of the second body portion, said rim portion having the shape of a parabola forming a smooth curve with and being an extension of the second body portion and opening toward the center of the aerodynamic toy, and a plurality of elevations extending rectilinearly along said upper convex side and radially outwardly from the said first body portion to points adjacent said rim and being integral with said second body portion.
Claim 3
Dependent Claim
24 words
An aerodynamic toy according to claim 1 wherein the said radial elevations are disposed equidistant angularly around the geometric center of the aerodynamic toy.
Claim 4
Dependent Claim
27 words
An aerodynamic toy according to claim 2 wherein the radial elevations are of greater width nearer the geometric center of the toy than nearer the rim portion.
Claim 5
Dependent Claim
