Title: Golf ball with grooved dimples
Inventor: GREEN STEPHEN M
IPC: A63B37/00
Filed: 2001-10-31
Abstract: A new configuration for dimples on the surface of a golf ball (2) is characterized by a plurality of grooves (12, 112, 212) in the concave surface (8) of the dimple (10, 110). The grooves (12) are concentrically arranged relative to the geometric configuration defined at the intersection with the spherical surface.
