Claims
- 1. A game ball, comprising:a spherical shell; a receptacle formed in said shell for receiving a chemoluminescent light source; weight means for adding mass to said ball, said weight means comprising an equatorial ring weight extending around an equator of said shell adjacent said interior shell surface, and a pair of circumferential polar ring weights spaced apart from said equatorial ring weight and extending around said interior shell surface at opposite poles of said sphere, whereby said weight means compensates for perturbations in the rotational moments of inertia of the ball.
- 2. The game ball of claim 1 wherein at least a portion of the surface area of said shell is translucent.
- 3. The game ball of claim 1 wherein a major portion of the surface area of said shell is translucent.
- 4. The game ball of claim 1 including a chemoluminescent light stick received in said receptacle.
- 5. The game ball of claim 1 wherein said receptacle comprises a longitudinal axial tube extending through said shell and opening to the outer shell surface on at least one end thereof.
- 6. The game ball of claim 5 wherein said spherical shell has a hollow core defined by an interior shell surface.
- 7. The game ball of claim 5 wherein said equatorial ring weight defines an equatorial plane and said axial tube extends through said sphere transverse to said equatorial plane.
- 8. The game ball of claim 7 wherein said polar weight rings lie in planes that are coplanar with said equatorial plane.
- 9. The game ball of claim 5 including a rib within said axial tube extending toward the axis thereof and configured for contacting a light stick received within said axial tube.
- 10. The game ball of claim 9 including plural ribs.
- 11. The game ball of claim 10 including diametrically opposed ribs within said axial tube defining a serpentine path through said axial tube.
- 12. The game ball of claim 1 wherein said shell comprises a first material and said weights comprise a second material that is different from said first material.
- 13. The game ball of claim 12 wherein said second material is of higher density than said first material.
- 14. The game ball of claim 1 in which said translucent spherical shell includes light scattering means for scattering light emitted by a light stick received within said receptacle.
- 15. The game ball of claim 14 in which said light scattering means comprise scattering centers contained within said shell.
- 16. The game ball of claim 15 in which said scattering centers include glass beads contained within said shell.
- 17. The game ball of claim 14 in which said light scattering means comprise bubbles contained within said shell.
- 18. The game ball of claim 1 including an equatorial band extending around an equator of said ball, said band being colored differently from said shell.
- 19. The game ball of claim 18 in which said band is translucent.
- 20. The game ball of claim 18 wherein said band is opaque.
- 21. A game ball, comprising:a spherical shell having an outer shell surface and a hollow core defined by an inner shell surface, said shell formed of a first material and wherein at least a portion of said shell is translucent; a receptacle in said shell for receiving a chemoluminescent light source; a weight contained in said hollow core and formed of a second material that has a greater density than said first material, said weight comprising a first circumferential ring extending around an equator of said shell within the core, and second and third circumferential rings within the core and positioned on opposite sides of said first circumferential ring, and wherein said circumferential rings define coplanar ring planes.
- 22. The game ball of claim 21 wherein said weight is fixed within said hollow core adjacent said inner shell surface.
- 23. The game ball of claim 21 including a chemoluminescent light stick received in said receptacle.
- 24. The game ball of claim 23 wherein said receptacle comprises a tube extending through said shell and opening to the outer shell surface on at least one end thereof.
- 25. The game ball of claim 21 wherein said tube extends axially through said shell and each opposite end of said tube opens to said outer shell surface.
