Abstract

A golf ball (20) having a non-planar parting line (25), a first false non-planar parting line (26a) and a second false non-planar parting line (26b). A first group 32 of parting dimples defines the non-planar parting line (25). A second group (33) of parting dimples defines the first false non-planar parting line (26a). A third group (34) of parting dimples defines the second false non-planar parting line (26b). A plurality of hexispheres (70) are defined by the non-planar parting line (25) the first false non-planar parting line (26a) and the second false non-planar parting line (26b).

Claims

a plurality of partitioning dimples comprising

a first group of the plurality of partitioning dimples positioned about an equator of the golf ball to define a non-planar parting line for the golf ball, the first group of partitioning dimples having a first row of partitioning dimples and a second row of partitioning dimples offset from the first row of partitioning dimples,

a second group of the plurality of partitioning dimples positioned around the golf ball to define a first false non-planar parting line for the golf ball, the second group of partitioning dimples having a third row of partitioning dimples and a fourth row of partitioning dimples offset from the third row of partitioning dimples, the first false non-planar parting line positioned approximately at an angle of sixty degrees to the non-planar parting line, and

a third group of the plurality of partitioning dimples positioned around the golf ball to define a second false non-planar parting line for the golf ball, the third group of partitioning dimples having a fifth row of partitioning dimples and a sixth row of partitioning dimples offset from the fifth row of partitioning dimples, the second false non-planar parting line positioned approximately at an angle of sixty degrees to the non-planar parting line.

2. The golf ball according to claim 1 wherein the plurality of partitioning dimples further comprises a plurality of primary-intersecting dimples and a plurality of secondary-intersecting dimples, the primary-intersecting dimples defining an intersection of the first group, second group and third group of the plurality of partitioning dimples, and the secondary-intersecting dimples defining an intersection of at least two of the first group, second group and third group of the plurality of partitioning dimples.

3. The golf ball according to claim 1 wherein the plurality of non-partitioning dimples and the plurality of partitioning dimples cover from 82% to 87% of a surface area of the golf ball.
