Abstract

An illuminated sports ball including flexible transparent tubing on its exterior for housing and exposing flexible light sources. The tubing is recessed in grooves around the ball so that only a portion thereof projects outward from the exterior surface of the ball. In one embodiment, the grooves terminate at common points on the ball and a central throughbore extends through the ball between these common points. An anchor cord which extends through a bore within the ball may be attached to the ends of the tubes to secure the tubes in the grooves. The tubes may extend within the ball to attach to the anchor cord, or to other tubes positioned around the ball. The light sources are chemiluminescent light sticks which are inserted into the tubes through a central slot. The slot desirably faces the grooves during use and the tubes are torsionally flexible and can be rotated to face outward for inserting the light sticks. In one embodiment the grooves extend in direct paths around the exterior periphery of the ball, while in a second embodiment the grooves follow non-linear paths around the ball.

Claims

an elongated flexible hollow tubular substantially transparent housing element adapted to receive a light-emitting source and sized to fit within said groove and extend between said two points, wherein said housing element comprises a transparent housing sized to receive a flexible chemiluminescent light stick.

6. The ball of claim 5, further comprising two grooves formed in said exterior surface each sized to receive one of said housing elements, said housing elements connected together at two junctions to help retain said housing elements in said grooves.

7. The ball of claim 6, wherein said ball is a football and said two points are common to both grooves and are located at opposite noses of said football.

8. The bail of claim 6, wherein said ball is a football and said grooves are both located substantially within a common axial plane of said ball.

9. The ball of claim 5, wherein each housing includes a slot for insertion and removal of said light sticks.

10. The ball of claim 9, wherein the length of each tubular housing and the length of the slot within the housing are such that the distance from one end of said housing to a distal end of said slot is sufficient to facilitate insertion of said light stick through said slot into said housing.

11. The ball of claim 10, wherein said slot is centered in said tubular housing between said two points.

12. The ball of claim 9, wherein said housings have torsional flexibility and said slot is positioned around the circumference of said housing element so as to face said groove in a relaxed orientation of said housing element, said slot being accessible to the exterior of said ball by twisting said housing.

13. The ball of claim 5, wherein said body is a foam-type material.

14. The ball of claim 13, further including:

a bore extending through said ball; and

an anchor cord within said bore attached to both ends of said housing element to help retain said housing element within said groove.

15. The ball of claim 14, wherein said anchor cord comprises a length of said housing.

16. The ball of claim 14, further comprising two grooves formed in said exterior surface each sized to receive one of said housing elements, said housing elements both connected to said anchor cord to help retain said housing elements in said grooves.

17. The ball of claim 16, wherein said grooves meet at two points located at the intersection of said bore and said exterior surface, said housing elements being connected to said anchor cord at said two points.

18. The ball of claim 14, further comprising two grooves formed in said exterior surface each sized to receive one of said housing elements, wherein each of said grooves terminates at points on said exterior surface and said ball further comprises channels connecting said points with said bore, said housing elements extending within the channels into the interior of the ball and being connected to said anchor cord at the intersection of said bore and said channels.
