Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
In a flying disc of the type comprising a circular central portion having substantially planar top and bottom surfaces and a sidewall integral with and depending from said central portion around the entire periphery thereof, the improvement which comprises: an annular weighted member concentric with said disc and secured to the internal surface of said sidewall, the weight of said annular weighted member being substantially eveny distributed about the center of said disc; and an additional weighted member disposed at the center of said disc with its weight substantially evenly distributed thereabout, said additional weighted member depending from said bottom surface and extending no lower than the plane defined by the free edge of said sidewall, the width of said additional weighted member being substantially less than the diameter of said disc.
Claim 2
Dependent Claim
132 words
In a flying disc of the type comprising a circular central portion having substantially planar top and bottom surfaces and a sidewall integral with and depending from said central portion around the entire periphery thereof, the improvement which comprises: an annular weighted member concentric with said disc and secured to the internal surface of said sidewall, the weight of said annular weighted member being substantially eveny distributed about the center of said disc; and an additional weighted member disposed at the center of said disc with its weight substantially evenly distributed thereabout, said additional weighted member depending from said bottom surface and extending no lower than the plane defined by the free edge of said sidewall, the width of said additional weighted member being substantially less than the diameter of said disc.
Claim 3
Dependent Claim
14 words
The device of claim 1, wherein said additional weighted member terminates above said plane.
Claim 4
Dependent Claim
12 words

Claim 5
Dependent Claim
13 words
The device of claim 1, wherein said additional weighted member is cylindrically shaped.
Claim 6
Dependent Claim
12 words
The device of claim 1, wherein said additional weighted member is annular.
Claim 7
Dependent Claim
40 words
The device of claim 1, wherein the ratio of the weight of the flying disc to the weight of the weighted members is greater than or equal to 2 to 1 but less than or equal to 8 to 1.
Claim 8
Dependent Claim
13 words
The device of claim 6, wherein said ratio is about 4 to 1.
