Abstract
Golf balls having dimple patterns arranged in dipyramid layouts are disclosed. The patterns may be arranged in triangular dipyramid, quadrilateral dipyramid, pentagonal dipyramid, or hexagonal dipyramid layouts. The dipyramid patterns have six, eight, ten, or twelve substantially identical dimple sections, where each dimple section is defined by a spherical triangle. The dimples in each of the identical dimple sections have at least two different dimple diameters including a minimum dimple diameter and a maximum dimple diameter. The resulting dimple patterns have a surface coverage of about 70 percent or less. The reduced surface coverage helps to reduce the flight of the golf balls.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A golf ball having a dimple pattern disposed on a substantially spherical surface, wherein the dimple pattern comprises:
a plurality of dimples arranged in a dipyramid pattern comprising ten or twelve substantially identical dimple sections, wherein each dimple section is defined by a spherical triangle, wherein the dimples in each of the substantially identical dimple sections comprise at least two different dimple diameters including a minimum dimple diameter and a maximum dimple diameter, wherein each substantially identical dimple section comprises at least one shared dimple located on at least one vertex of the dimple section and the at least one shared dimple has the maximum dimple diameter, and wherein the dimples cover about 70 percent or less of the substantially spherical surface.
2 . The golf ball of claim 1 , wherein the dimple pattern results in one dimple free great circle on the golf ball.
3 . The golf ball of claim 1 , wherein each of the at least two different dimple diameters range from about 0.030 inches to about 0.200 inches.
4 . The golf ball of claim 1 , wherein the pattern has mirror symmetry about a central plane of each substantially identical dimple section.
5 . The golf ball of claim 1 , wherein the dimples each have a corresponding edge angle and the average of all the edge angles (θ u ) is related to the surface coverage according to equation (III):

6 . The golf ball of claim 1 , wherein the at least one shared dimple is located on each vertex of the dimple section.
7 . A golf ball having a dimple pattern disposed on a substantially spherical surface, wherein the dimple pattern comprises:
a plurality of dimples arranged in a dipyramid pattern comprising ten or twelve substantially identical dimple sections, wherein each dimple section is defined by a spherical triangle, wherein the dimples in each of the substantially identical dimple sections comprise at least three different dimple diameters including a minimum dimple diameter, a maximum dimple diameter, and at least one additional dimple diameter, wherein each of the at least three different dimple diameters range from about 0.030 inches to about 0.200 inches, wherein each substantially identical dimple section comprises at least one shared dimple located on at least one vertex of the dimple section and the at least one shared dimple has the maximum dimple diameter, and wherein the dimples cover about 70 percent or less of the substantially spherical surface.
8 . The golf ball of claim 7 , wherein the dimples cover about 50 percent or less of the substantially spherical surface.
9 . The golf ball of claim 7 , wherein the at least one shared dimple is located on a single vertex of the dimple section.
10 . The golf ball of claim 7 , wherein the dimple pattern results in one dimple free great circle on the golf ball.
11 . The golf ball of claim 7 , wherein the average of all the edge angles (θ u ) is related to the surface coverage according to equation (III):

12 . The golf ball of claim 7 , wherein the maximum difference in diameter between any two dimples within each dimple section is about 0.080 inches or less.
13 . The golf ball of claim 7 , wherein the pattern has mirror symmetry about a central plane of each substantially identical dimple section.
14 . A golf ball having a dimple pattern disposed on a substantially spherical surface, wherein the dimple pattern comprises:
a plurality of dimples arranged in a dipyramid pattern comprising ten or twelve substantially identical dimple sections, wherein each dimple section is defined by a spherical triangle, wherein the dimples in each of the substantially identical dimple sections comprise five or more different dimple diameters including a minimum dimple diameter, a maximum dimple diameter, and at least three additional dimple diameters, wherein each of the five or more different dimple diameters range from about 0.030 inches to about 0.180 inches and differ by more than 0.005 inches, wherein each substantially identical dimple section comprises at least one shared dimple located on at least one vertex of the dimple section and the at least one shared dimple has the maximum dimple diameter, and wherein the dimples cover about 70 percent or less of the substantially spherical surface.
15 . The golf ball of claim 14 , wherein the dimple pattern results in one dimple free great circle on the golf ball.
16 . The golf ball of claim 14 , wherein the dimples in each of the substantially identical dimple sections comprise substantially identical edge angles.
17 . The golf ball of claim 14 , wherein the average of all the edge angles (θ u ) is related to the surface coverage according to equation (III):
