Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 82 words
In a tethered flying disc device, a disc having means for producing gyroscopic and lift effects when cast in the air with a spinning action, including a convex upper surface, a reel portion, said reel portion having a stem coaxial with said disc, said stem being integrated with said disc, with said reel portion disposed below said disc for accommodating a line to be unwound and wound on said reel portion, and a line secured at one end on said reel portion.
Claim 2
Dependent Claim 82 words
In a tethered flying disc device, a disc having means for producing gyroscopic and lift effects when cast in the air with a spinning action, including a convex upper surface, a reel portion, said reel portion having a stem coaxial with said disc, said stem being integrated with said disc, with said reel portion disposed below said disc for accommodating a line to be unwound and wound on said reel portion, and a line secured at one end on said reel portion.
Claim 3
Dependent Claim 42 words
In a tethered flying disc device as defined in claim 1, said reel portion having a stem depending from the undersurface of said disc, and a weight beneath said reel portion whereby the center of gravity of the device is adjusted downwardly.
Claim 4
Dependent Claim 46 words
In a tethered flying disc device as defined in claim 1, said reel portion having a stem depending from the undersurface of said disc, and shock absorber means beneath said reel portion providing a weight whereby the center of gravity of the device is adjusted downwardly.
Claim 5
Dependent Claim 41 words
In a tethered flying disc device as defined in claim 1, said reel portion having means for preventing said line from dragging on said reel as said disc is cast at a positive angle of attack and during normal flight attitudes.
Claim 6
Dependent Claim 120 words
In a tethered flying disc device as defined in claim 1, said reel portion having means for preventing said line from dragging on said reel as said disc is cast at a positive angle of attack and during normal flight attitudes including a V-shaped groove defined by an upper wall extending at an angle relative to a plane normal to the axis of the reel and intersecting the base of the V-shaped groove which is smaller than the angle defined between said plane and the lower edge of the disc at its outer periphery and a lower wall which defines an angle relative to said plane larger than the angle between said plane and the line during normal flight attitudes.
