DISC AMUSEMENT DEVICE
A flying disc has an outer annular doughnut-shaped hollow ring surrounding a generally planar central portion. The annular ring is permanently inflated to a high pressure. The flying disc is formed of a thermoplastic plastomer or elastomer and is capable of bouncing 20-25 feet after landing, and rolling an additional distance if it lands on its outer edge.
1 . A game or amusement device in the form of a flying disc, comprising:
a peripheral doughnut-shaped hollow ring surrounding a generally planar central portion,
the hollow ring being permanently inflated to a pressure of at least 0.9 kg/cm 3 ,
the flying disc having a wall thickness of at least 72.8 mils, and
the flying disc being injection molded of a flexible thermoplastic plastomer or elastomer.
2 . The flying disc of claim 1 , comprising a curved transition area between the planar surface interior and the doughnut-shaped ring, the curved area providing the beginning of a concave shape.
3 . The flying disc of claim 2 which is symmetrical, both top and bottom.
4 . The flying disc according to claim 1 wherein said thermoplastic material is selected from the group consisting of a thermoplastic polyurethane, polyethylene, polypropylene, silicone and polyvinyl chloride.
5 . The flying disc of claim 4 wherein the thermoplastic material is a thermoplastic polyurethane.
6 . The flying disc of claim 1 , wherein the, doughnut-shaped hollow portion has a height-to-width ratio of about 4.5 to 6.
7 . The flying disc of claim 1 inflated to a pressure of at least 1.2 kg/cm 3 .
8 . The flying disc of claim 1 wherein said peripheral donut-shaped hollow ring has a height which is less than the distance between its outer edge and its inner edge.
9 . The injection molded flying disc of claim 1 comprising said generally planar central portion as a single layer, and wherein said single layer generally planar central portion is integral and unitary with said peripheral doughnut-shaped hollow ring.
10 . The injection molded flying disc of claim 1 wherein said generally planar central portion is imperforate.
11 . The injection molded flying disc of claim 1 wherein said generally planar central portion comprises a single layer.
12 . A game or amusement device in the form of a flying disc having a top and a bottom, comprising
a peripheral doughnut-shaped hollow ring surrounding a generally planar central portion comprising a single layer,
the hollow ring comprising a single layer and being permanently inflated to a pressure of at least 0.9 kg/cm 3 ,
the single layer of said generally planar central portion and the single layer of the peripheral doughnut-shaped hollow ring having a thickness of at least 72.8 mils, and
the flying disc being integrally molded as a unitary device of a flexible thermoplastic plastomer or elastomer.
13 . The flying disc of claim 12 , comprising a curved transition area between the planar surface and the doughnut-shaped ring, the curved transition area providing the beginning of a concave shape.
14 . The flying disc of claim 13 which is symmetrical on said top and said bottom surfaces.
15 . The flying disc according to claim 12 wherein said thermoplastic material is selected from the group consisting of a thermoplastic polyurethane, polyethylene, polypropylene, silicone and polyvinyl chloride.
16 . The flying disc of claim 15 wherein the thermoplastic material is a thermoplastic polyurethane.
17 . The flying disc of claim 12 wherein said peripheral doughnut-shaped hollow ring has a dimension between said top and said bottom which is less than a distance between its outer edge and its inner edge.
18 . The flying disc of claim 17 wherein the doughnut-shaped hollow portion has a ratio of the distance between said top and bottom surface to the distance between the outer edge and inner edge thereof of about 4.5 to 6.
19 . The flying disc of claim 12 inflated to a pressure of at least 1.2 kg/cm 3 .
