US Patent:

6705957, Mar 16, 2004

Filed:

Nov 29, 1999

Appl. No.:

09/450137

Inventors:

Timothy M. Owens - Fort Mill SC 29715
Douglas P. DuFaux - Charlotte NC 28207
Mark T. Elliott - Charlotte NC 28211
Kris H. Turschmid - Charlotte NC 28210

International Classification:

A63B 3704

US Classification:

473372, 473375, 473369

Abstract:

A golf ball having improved driving characteristics includes a hard, hollow sphere surrounded by an outer. A second layer may be disposed between the sphere and the outer cover. The hollow sphere is made from a hard material such as a metal, metal alloy, or intermetallic material and may be solid, perforated or porous. The second layer surrounding the sphere is generally made of a natural rubber or synthetic polymer or a combination of each which is surrounded by an outer cover made of an ionomer, urethane or balata. The hard sphere preferably contains a gas. A golf ball of this construction has improved performance characteristics such as low spin rate and further distance.

International Classification:

A63B 37/04

US Classification:

473371000

Abstract:

A golf ball is provided that has a hard sphere core or layer that exhibits a controlled vibrational response. The vibrational response may be controlled by tailoring the stiffness or damping of the sphere with at least one element, such as a groove(s) or any other type of indentation in the hard sphere core. The groove (or grooves) serves to locally reduce the wall thickness of the hollow metal sphere core, thereby reducing the stiffness of the core by allowing larger deformations under a load without significantly reducing the total mass of the core. This results in a golf ball that is legal for play and capable of drive distances essentially equivalent to those of currently available high performance golf balls, but that also maintains a high moment of inertia, allowing less hooks and slices during play.
