Abstract

The present invention relates to softballs (10) that have very low compression, but maintain the traditional COR values of standard urethane co re softballs. The present invention comprises a softball (10) having a central core (12) and at least one core or mantle layer (14, 15) to produce a softba ll (10) having the performance of a traditional ball (10).

Claims (20)

1. A improved game ball (10) characterized by:
a central core (12);
a first mantle layer (14) surrounding said central core (12); and a cover (16) surrounding said first mantle layer (14).
2. The improved game ball (10) as described in claim 1, wherein said central core (12) comprises a first urethane composition.
3. The improved game ball (10) as described in claim 2, wherein said first urethane composition includes a first mixture of a polyol and an isocyanate.
4. The improved game ball (10) as described in claim 1, wherein said first mantle layer (14) comprises a second urethane composition.
5. The improved game ball (10) as described in claim 4, wherein said first urethane composition includes a second mixture of a polyol and an isocyanate.
6. The improved game ball (10) as described in claim 2 further comprising:
a second mantle layer (15) surrounding said first mantle layer (14), said second mantle layer (15) positioned between said first mantle layer (14) and said cover (16).
7. The improved game ball (10) as described in claim 5, wherein said second mantle layer (15) comprises a third urethane composition.
8. The improved game ball (10) as described in claim 7, wherein said third urethane composition includes a first mixture of a polyol and an isocyanate.
9. The improved game ball (10) as described in claim 5 wherein said central core (12) comprises a diameter substantially between 3.40 inches and 3.44 inches.
10. The improved game ball (10) as described in claim 5 wherein said first mantle layer (14) comprises a thickness of substantially between 0.05 inches and 0.500 inches.
11. The improved game ball (10) as described in claim 5 wherein said second mantle layer (15) comprises a thickness of substantially between 0.05 inches and 0.25 inches.
12. The improved game ball (10) as described in claim 1, wherein said composite core has a coefficient of restitution at 88 feet-per-second within the range of 0.40 and 0.50.
13. The improved game ball (10) as described in claim 1, wherein the compression of said softball (10) is less than 475 pounds.
14. A multi-layer softball (10) comprising:
a composite core including a central core (12) having a first urethane composition and a first mantle layer (14) having a second urethane composition; and a cover (16) surrounding said composite core.
15. The multi-layer softball (10) as described in claim 14 further comprising:
a second mantle layer (15) surrounding said first mantle layer (14), said second mantle layer (15) positioned between said first mantle layer (14) and said cover (16).
16. The multi-layer softball (10) as described in claim 15, wherein said second mantle layer (15) comprises a third urethane composition.
17. The multi-layer softball (10) as described in claim 14 Wherein said central core (12) comprises a diameter substantially between 3.40 inches and 3.44 inches.
18. The multi-layer softball (10) as described in claim 14 wherein said first mantle layer (14) comprises a thickness of substantially between 0.05 inches and 0.500 inches.
19. The multi-layer softball (10) as described in claim 14, wherein said composite core has a coefficient of restitution at 88 feet-per-second within the range of 0.40 and 0.50.
20. The multi-layer softball (10) as described in claim 1, wherein the compression of said softball (10) is less than 475 pounds.
