Abstract
The present invention provides a golf ball having an aerodynamic subsurface for packing dimples. More particularly, the invention relates to a golf ball having an exterior surface and at least a first subsurface containing at least two dimples located solely on the subsurface and lying below the exterior surface of the golf ball. The present invention also describes a method for creating the dimple pattern including providing a spherical section having an exterior surface and at least a first subsurface, arranging at least two dimples located solely on the first subsurface and then tessellating the spherical surfaces around the golf ball.
Claims24
A golf ball comprising:
- a core;
- a cover surrounding the core;
- an exterior surface provided on the cover having an exterior radius R0;
- at least a first subsurface having a first perimeter and a subsurface radius R1 and at least two dimples located solely within the first subsurface,
- wherein the first subsurface is offset from the exterior surface by a value δ1 such that R1=R0−δ1 and δ1 is between about 0.009 and about 0.020 inches.
A golf ball comprising:
- a core;
- a cover surrounding the core;
- an exterior surface provided on the cover having an exterior radius R0;
- at least a first subsurface having a non-circular first perimeter and a subsurface radius R1 and at least two dimples located solely within the first subsurface,
- wherein the first subsurface is offset from the exterior surface by a value δ1 such that R1=R0−δ1 and δ1 is between about 0.003 and about 0.015 inches,
- wherein the first subsurface is spherical and concentric to the exterior surface;
- and
- wherein at least three dimples provided on the first subsurface adjacent the first perimeter have a dimple perimeter and at least 20 percent of the dimple perimeter is within about 0.010 inches of the first perimeter.
