Abstract

A recreational or competitive flying disc includes an illumination system employing an array of flexible optical fibers to distribute the light of a single light emitting diode (LED) from the rotational center of the disc to its outside periphery. A small water-resistant compartment centered on the underside of the disc houses the LED, battery, and the illumination control. The leads of the LED also serve as the contacts of the battery. One end of each of the optical fibers is embedded in the LED, and the other end extends radially from the central housing on the underside surface of the disc to the rim of the disc. The flying disc is illuminated without altering the aerodynamic properties of the disc.

Claims

1. A flying disc comprising:

a disc-shaped body member having a first surface and a second surface and terminating at its periphery in an annular rim;

said first surface being essentially flat;

said rim extending in a direction substantially away from the plane of said first surface and together with said second surface defining a semi-enclosed space;

an electronics assembly located on said second surface within said semi-enclosed space, said electronics assembly including an electronic power source, a light source connected to said power source, and an optical fiber located to receive light from said light source; and

a raised rib on said second surface, said optical fiber attached to said rib.

2. A flying disk as in claim 1 wherein at least a portion of said rib extends toward said annular rim.

3. A flying disc as in claim 2 wherein there are a plurality of said raised ribs extending toward said annular rim and a plurality of said optical fibers, each of said optical fibers attached to one of said ribs.

4. A flying disc as in claim 1 and further having a channel formed in said rib, and wherein said optical fiber is located in said channel.

5. A flying disc as in claim 4 wherein there are a plurality of said ribs and a plurality of said optical fibers, each of said optical fibers located in one of said channels in one of said ribs.

6. A flying disc as in claim 5 wherein said channels include a lip for retaining said optical fibers.

7. A flying disc as in claim 4 wherein said channels abut but do not penetrate the inside edge of said rim.

8. A flying disc as in claim 1 wherein said electronics housing includes a base member, a battery, and a cap wherein said battery is located between said base member and said cap.

9. A flying disc as in claim 8 wherein said base substantially surrounds said battery.

10. A flying disc as in claim 8 wherein said cap is rotatable relative to said base member.

11. A flying disc as in claim 10 wherein said electronics assembly includes a switch operable by rotation of said cap.

12. A flying disc as in claim 8 wherein said cap includes a protrusion centrally located on said cap and extending toward said battery when said cap and base member are engaged.

13. A flying disc as in claim 1 wherein said electronic power source, said light source, said rib, and said optical fiber are located entirely within said semi-enclosed space.

14. A flying disc as in claim 1 wherein said disc-shaped body, said rim, and said rib are translucent.

15. A method of illuminating a flying disc, said method comprising:

providing a disc-shaped body member having a first surface and a second surface and terminating at its periphery in an annular rim;

said first surface being essentially flat;

said rim extending in a direction substantially away from the plane of said first surface;

forming a raised rib on said second surface;

attaching an optical fiber to said rib; and

illuminating said optical fiber.

16. A method as in claim 15 wherein said forming a rib includes forming a channel in said rib and said attaching comprises placing said optical fiber in said channel.

17. A method as in claim 15 wherein said forming comprises forming a plurality of said raised ribs and said attaching comprises attaching an optical fiber to each of said ribs.

18. A method as in claim 15 wherein said annular rim together with said second surface define a semi-enclosed space and said forming comprises forming said rib within said semi-enclosed space.

19. A method as in claim 15 wherein said forming comprises forming at least a portion of said rib extending toward said annular rim from an area near the center of said second surface.

20. A method as in claim 15 wherein said providing further comprises providing on said second surface an electronics housing including a base member, a battery, and a cap, with said battery located between said base member and said cap;

and said illuminating comprises rotating said cap.
