Abstract
Abstract The present invention relates to an improved double flying disc including two discs attached together in vertically stacked relation by a plurality of collapsible rings. The device is thrown with the discs adjacent one another and, during flight, the discs separate from one another as the connecting rings allow such separation until the rings are opened as far as they can open due to their interactions with one another. After the double flying disc lands, the rings collapse, allowing the discs to be adjacent one another and ready for the next throw.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
An improved double flying disc comprising: (a) a first disc having a convex upper surface and a concave undersurface; (b) a second disc having a convex upper surface and a concave undersurface; and (c) connection means connecting said first disc undersurface to said second disc upper surface, said connection means allowing relative movement of said discs with respect to one another, said connection means comprising a telescoping device allowing said discs to move toward and away from one another.
Claim 2
Dependent Claim
79 words
An improved double flying disc comprising: (a) a first disc having a convex upper surface and a concave undersurface; (b) a second disc having a convex upper surface and a concave undersurface; and (c) connection means connecting said first disc undersurface to said second disc upper surface, said connection means allowing relative movement of said discs with respect to one another, said connection means comprising a telescoping device allowing said discs to move toward and away from one another.
Claim 3
Dependent Claim
35 words
The invention of claim 1, wherein said telescoping device comprises a plurality of rings of successively increasing dimensions each said ring having a truncated conical cross-section, said rings being expandable as a group without separating.
Claim 4
Dependent Claim
73 words
The invention of claim 2, wherein said plurality of rings comprises at least three rings, a first ring attached at its smallest diameter to said first disc undersurface, a second ring attached at its largest diameter to said second disc upper surface and a third ring having a smallest diameter smaller than the largest diameter of said first ring, and having a largest diameter larger than the smallest diameter of said second ring.
