GOLF BALL HAVING CIRCULAR GROUPS OF TEAR-DROPPED DIMPLES

摘要

A golf ball (2) having improved aerodynamic efficiency is characterized by the arrangement of a pluraliy of modified tear-drop shaped dimples (10, 20) arranged on the surface thereof. The ball has a dimple-free equator (E) which divides the ball into two identical hemispheres, each of which is broken into equal quadrants by two great circles (4, 6) passing through the poles (P) of the ball (2). Each quadrant has a maximum circular area (8) filled with a first plurality of non-symmetric, tear-drop shaped dimples (10). A second plurality of non-symmetric, tear-drop shaped dimples (20) is arranged between the circular areas (8), so that the dimple coverage on the ball (2) is maximized.
