Abstract
Abstract A molded flying disc with most of the weight concentrated in an outer annular ring and the central area in the ring covered by a thin lightweight sheet of material different from the molded material of the same thickness and diameter. The ring has a locking structure to hold an interlocking weight ring that may include another locking structure to hold an additional weight ring. The lightweight sheet may be colored or have artwork, such as a hologram, thereon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A flying disc comprising: an annular member molded of a first material, the inner perimeter of the annular member defining an open inner area in a plane, and the annular member comprising an outer rim with an air-foil-shaped cross-section curved away from the plane defined by the inner perimeter and having a convex outwardly facing surface, the outer rim having an inwardly facing surface; a thin, flat sheet of a different material having a higher strength-to-weight ratio for its thickness than the first material at the same thickness and having an outer perimeter affixed to the annular member to cover the open inner area; and a weight ring comprising an outwardly facing surface, the outwardly facing surface of the weight ring and the inwardly facing surface of the rim comprising interlocking means to hold the weight ring connected to the rim.
Claim 2
Dependent Claim
