Abstract

Abstract A flying disc toy has at least two circular spinners rotatably mounted upon a centered axle. Each spinner has a number of fins which cause the spinner to rotate when thrown into the air. The spinners rotate in counter direction, thereby causing the toy to lift when thrown with a twisting motion. The subject matter of this application is disclosed in Disclosure Document #254258, dated June 4, 1990.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 202 words
A flying-saucer type toy comprised of: a) top and bottom spinners rotatably disposed upon a centered axle and in close proximity, said spinners comprised of: 1) a central hub having a vertical bore which receives said axle. 2) a rigid outer circular rim in coplanar alignment with said hub, said rim comprised of a circumferential surface having upper and lower edges and a gripping flange outwardly extending from said circumferential surface. 3) a plurality of uniformly spaced elongated fins having proximal and distal extremities, upper and lower surfaces, and leading and trailing edges, said proximal extremities fixedly associated with said hub, said distal extremities fixedly associated with said rim, said fins being pitched to dispose said leading edges in coplanar alignment, and said trailing edges in coplanar alignment, thereby disposing said upper surfaces at a uniform pitch, b) a vertical axle journaled to said bores and having upper and lower extremities, and c) retaining members associated with the upper and lower extremities of said axle, said retaining members maintaining said spinners in close proximity upon said axle, d) whereupon throwing of the toy by contacting said gripping edges, the spinners are counter rotated upon release to cause said fins to generate lift.
Claim 2
Dependent Claim 202 words
A flying-saucer type toy comprised of: a) top and bottom spinners rotatably disposed upon a centered axle and in close proximity, said spinners comprised of: 1) a central hub having a vertical bore which receives said axle. 2) a rigid outer circular rim in coplanar alignment with said hub, said rim comprised of a circumferential surface having upper and lower edges and a gripping flange outwardly extending from said circumferential surface. 3) a plurality of uniformly spaced elongated fins having proximal and distal extremities, upper and lower surfaces, and leading and trailing edges, said proximal extremities fixedly associated with said hub, said distal extremities fixedly associated with said rim, said fins being pitched to dispose said leading edges in coplanar alignment, and said trailing edges in coplanar alignment, thereby disposing said upper surfaces at a uniform pitch, b) a vertical axle journaled to said bores and having upper and lower extremities, and c) retaining members associated with the upper and lower extremities of said axle, said retaining members maintaining said spinners in close proximity upon said axle, d) whereupon throwing of the toy by contacting said gripping edges, the spinners are counter rotated upon release to cause said fins to generate lift.
Claim 3
Dependent Claim 29 words
The toy of claim 1 wherein the pitch of the fins of said top spinner is equal but opposite to the pitch of the fins of said bottom spinner.
Claim 4
Dependent Claim 22 words
The toy of claim 1 wherein the top and bottom spinners are identical except for the direction of pitch of said fins.
Claim 5
Dependent Claim 16 words
The toy of claim 1 wherein said spinners are monolithic structures fabricated from a thermoplastic resin.
Claim 6
Dependent Claim 173 words
A flying-saucer type toy comprised of: a) top and bottom spinners and a third spinner disposed between said top and bottom spinners, said spinners being rotatably disposed upon a centered axle and comprised of: 1) a central hub having a vertical bore which receives said axle, 2) a rigid outer circular rim in coplanar alignment with said hub, said rim comprised of a circumferential surface having upper and lower edges and a gripping flange outwardly extending from said circumferential surface, 3) a plurality of uniformly spaced elongated fins having proximal and distal extremities, upper and lower surfaces, and leading and trailing edges, said proximal extremities fixedly associated with said hub, said distal extremities associated with said rim, said fins being pitched to dispose said leading edges in coplanar alignment, and said trailing edges in coplanar alignment, thereby disposing said upper surfaces at a uniform pitch, b) a vertical axle journaled to said bores, and c) retaining members associated with said axle and serving to maintain said spinners in close proximity upon said axle.
Claim 7
Dependent Claim 173 words
A flying-saucer type toy comprised of: a) top and bottom spinners and a third spinner disposed between said top and bottom spinners, said spinners being rotatably disposed upon a centered axle and comprised of: 1) a central hub having a vertical bore which receives said axle, 2) a rigid outer circular rim in coplanar alignment with said hub, said rim comprised of a circumferential surface having upper and lower edges and a gripping flange outwardly extending from said circumferential surface, 3) a plurality of uniformly spaced elongated fins having proximal and distal extremities, upper and lower surfaces, and leading and trailing edges, said proximal extremities fixedly associated with said hub, said distal extremities associated with said rim, said fins being pitched to dispose said leading edges in coplanar alignment, and said trailing edges in coplanar alignment, thereby disposing said upper surfaces at a uniform pitch, b) a vertical axle journaled to said bores, and c) retaining members associated with said axle and serving to maintain said spinners in close proximity upon said axle.
Claim 8
Dependent Claim 46 words
The toy of claim 5 wherein the pitch of the fins of the top and bottom spinners are in the same direction, and the pitch of the fins of said third spinner is in a direction opposite to the pitch of said top and bottom spinners.
