Abstract
A game ball having a hollow core structure which is resistant to permanent denting or “oil canning” when struck with a bat. The game ball also has a higher moment of inertia due to its hollow construction and consequently has a lower spin rate making it more suitable for play in confined areas and for use by lower skilled players. The core of the ball is formed from a thermoset elastomeric material and the wall thickness of the game ball ranges from 10 to 36 mm.
Claims15
A hollow game ball comprising:
- a substantially spherical core defining a substantially spherical internal cavity, said core comprised of a cross-linked thermoset elastomeric material having a Shore C hardness within the range of 40 to 70;
- and
- a cover overlying said core.
