Abstract
A golf ball utilizing a high density core component, which is preferably part of a multicomponent core assembly is disclosed. The high density core component is preferably in the form of a metal sphere. The golf balls exhibit a unique combination of a relatively high coefficient of restitution, a controlled moment of inertia, and a relatively high spin rate during short distance shots. It is preferred that the high density core component be utilized in conjunction with a multi-layer cover assembly.
Claims19
A golf ball comprising:
- a solid spherical metal core component having a specific gravity of from about 1.5 to about 19.4;
- a core layer disposed about said spherical metal core component, said core layer having a specific gravity less than 1.2, said core component and said core layer forming a core assembly, said core assembly having a coefficient of restitution of at least 0.730;
- and
- a cover layer assembly disposed about said core layer.
A golf ball comprising:
- a solid spherical metal core component;
- and
- a core layer concentrically disposed about and immediately adjacent to said spherical metal core component, thereby forming a dual core assembly, wherein said dual core assembly exhibits a coefficient of restitution of at least about 0.780;
- and
- a cover layer assembly disposed about said core layer, wherein said cover layer comprises a polyurethane material.
A golf ball having a dimpled outer surface and exhibiting improved playability properties, said golf ball comprising:
- a solid metal core component having a specific gravity of at least about 1.5;
- a core layer disposed about said metal core component and having a specific gravity less than the specific gravity of said spherical metal core component, wherein said metal core component and said core layer constitute a dual core assembly, said dual core assembly exhibiting a coefficient of restitution of at least 0.780;
- and
- a multi-layer cover assembly disposed about said core layer and including (i) an inner cover layer disposed proximate said core layer, and (ii) an outer cover layer disposed immediately adjacent to said inner cover layer and defining an outer dimpled surface.
