Abstract

A golf ball product, or other non-streamlined body, having a dimple pattern in which at least some of the dimples overlap at least one adjacent dimple is disclosed. A new parameter called Overlap Saturation (OS) is disclosed. OS is the ratio of the number of overlap instances on a ball to the maximum possible number for an ideal hypothetical ball with the same number of dimples. Overlap instances are tallied by summing the number of overlapping neighbor dimples for every dimple. Golf ball products employing the disclosed dimple patterns have an increase in total yardage compared to an equivalent product without overlapping dimples.

Claims

1. A golf ball product, comprising:

an outer surface having dimples formed therein; and

a parting line;

wherein some of said dimples are aligned across said parting line and positioned to overlap across said parting line; and

wherein the golf ball product has an overlap saturation from approximately 40% to approximately 100%.

2. The golf ball product of claim 1, wherein said parting line is equatorial.

3. The golf ball product of claim 1, wherein all of said dimples adjacent said parting line are aligned with and positioned to overlap corresponding dimples across said parting line.

4. The golf ball product of claim 1, wherein a majority of said dimples overlap a plurality of adjacent ones of said dimples.

5. The golf ball product of claim 4, wherein a majority of said dimples overlap three or more adjacent dimples.

6. The golf ball product of claim 5, wherein a majority of said dimples overlap four or more adjacent dimples.

7. The golf ball product of claim 4, wherein a majority of said dimples overlap a majority of adjacent ones of said dimples.
