Dimple patterns for golf balls
View Patent ↗The present invention provides a golf ball wherein each hemisphere has a dimple pattern based on a pyramid having dissimilar sides. The resulting overall dimple pattern is not based on preexisting polyhedral, and is not attainable using conventional dimple packing methods.
1. A golf ball having a first hemisphere and a second hemisphere separated by an equator, each hemisphere comprising on the outer surface thereof a plurality of dimples arranged in a pattern defined by an n-sided pyramid projected on a hemisphere as n lines of longitude from pole to equator, wherein the dimple arrangement along each longitudinal line is identical, and wherein the golf ball has a flat parting line along the equator, wherein the number of sides on the first hemisphere is different from the number of sides on the second hemisphere.
2. A golf ball having a first hemisphere and a second hemisphere separated by an equator, each hemisphere comprising on the outer surface thereof a plurality of dimples arranged in a pattern defined by an n-sided pyramid projected on a hemisphere as n lines of longitude from pole to equator, wherein the dimple arrangement along each longitudinal line is identical, and wherein the golf ball has a flat parting line along the equator, wherein at least two of the sides of one hemisphere have a different longitudinal angle.
3. The golf ball of claim 2 , wherein the number of sides on the first hemisphere is the same as the number of sides on the second hemisphere.
4. The golf ball of claim 2 , wherein the overall dimple pattern of the first hemisphere is the same as the overall dimple pattern of the second hemisphere.
5. The golf ball of claim 2 , wherein the overall dimple pattern of the first hemisphere is not a mirror image of the overall dimple pattern of the second hemisphere.
6. The golf ball of claim 2 , wherein the overall dimple pattern of the first hemisphere is different than the overall dimple pattern of the second hemisphere.
7. A golf ball having a first hemisphere and a second hemisphere separated by an equator, each hemisphere comprising on the outer surface thereof a plurality of dimples arranged in a pattern defined by an n-sided pyramid projected on a hemisphere as n lines of longitude from pole to equator, wherein the dimple arrangement along each longitudinal line is identical, wherein the golf ball has a staggered parting line along the equator, wherein the number of sides on the first hemisphere is different from the number of sides on the second hemisphere.
8. A golf ball having a first hemisphere and a second hemisphere separated by an equator, each hemisphere comprising on the outer surface thereof a plurality of dimples arranged in a pattern defined by an n-sided pyramid projected on a hemisphere as n lines of longitude from pole to equator, wherein the dimple arrangement along each longitudinal line is identical, wherein the golf ball has a staggered parting line along the equator, wherein at least two of the sides of one hemisphere have a different longitudinal angle.
9. The golf ball of claim 8 , wherein the number of sides on the first hemisphere is the same as the number of sides on the second hemisphere.
10. The golf ball of claim 8 , wherein the overall dimple pattern of the first hemisphere is the same as the overall dimple pattern of the second hemisphere.
11. The golf ball of claim 8 , wherein the overall dimple pattern of the first hemisphere is not a mirror image of the overall dimple pattern of the second hemisphere.
12. The golf ball of claim 8 , wherein the overall dimple pattern of the first hemisphere is different than the overall dimple pattern of the second hemisphere.
