1. An aerodynamically-shaped circular flying disc comprisinga domed body having a circular central portion of a generally uniform cross-section and a downwardly depending skirt portion;
- anda separately integral circular rim portion having an upwardly opening passage extending annularly around the rim portion and a generally greater cross-sectional area than said central portion, said rim portion being secured to the skirt portion at the annular passage such that the rim portion brackets the skirt portion, the cross-sectional profile of the central portion and rim portion conforming to that of an airfoil.

Abstract
An aerodynamically-shaped flying disc comprised of two separate and distinct parts, a disc body portion and one or more separate rim portions. In one embodiment, the connection between the body and rim portions is permanent. In a second embodiment, the connection is disengageable to permit the use of interchangeable rim portions of different aerodynamic configurations, colors, dimensions and weights.

6. An aerodynamically-shaped flying disc comprising
a circular central body portion having a generally uniform cross section; -
an annular rim portion integrally formed with the body portion depending from the plane of the body portion to provide the disc with a skirt portion of predetermined length; and a deformable circular auxiliary portion having a cylindrical passage extending annularly around the auxiliary portion, said auxiliary portion being detachably engageable along the cylindrical passage with the interior and exterior side of said annular rim portion for providing disc profile and weighting adjustments whereby different disc flight characteristics are obtained. - View Dependent Claims (7, 8)

9. An aerodynamically-shaped flying disc comprising
a domed body having a central, generally flat, circular portion bounded by a bent outer portion providing the body portion with an upwardly-directed convex configuration and a downwardly-directed concave configuration, the central circular portion having a generally uniform cross-section; -
a separately integral annular rim portion of a predetermined weight and configuration having an axially oriented slot extending annularly around the rim portion whereby the rim portion brackets the bent outer portion when the slot and bent portion are engaged; and joining means provided in the body and rim portions for securely interengaging said portions.

11. Apparatus for providing an aerodynamically adjustable flying disc comprising a body portion and a separate rim portion;
-
the body portion being balanced about a center of rotation of the disc and having joining means located on a downwardly depending outer perimeter of the body portion for detachable engagement with the rim portion; and the rim portion having a predetermined weight and cross-sectional profile and an upwardly opening annular slot for receiving and continuously bracketing the entire outer perimeter of the body portion and engaging means for cooperatively interlocking with the joining means of the body portion to provide a disc having adjustable flight characteristics. - View Dependent Claims (12)
