Dimple patterns with surface texture for golf balls
View Patent ↗The present invention provides a golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing therein. The directional surface texturing preferably comprises substantially parallel channels or protrusions formed within the dimples.
1. A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing therein, wherein the directional surface texturing is comprised of a plurality of linear channels that are substantially parallel within the dimple.
2. A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing therein, wherein the directional surface texturing is comprised of a plurality of linear protrusions that are substantially parallel within the dimple.
3. The golf ball of claim 1 , wherein the linear channels have a maximum channel depth of less than ¼ of a dimple depth.
4. The golf ball of claim 1 , wherein a plurality of the linear channels have a channel length that is at least 5 times a width of the channel.
5. The golf ball of claim 1 , wherein the linear channels have a channel width that is substantially similar to a channel depth.
6. The golf ball of claim 1 , wherein the linear channels have a channel width that is greater than a channel depth and a length between adjacent linear channels is at least 2 times the channel width.
7. The golf ball of claim 2 , wherein the linear protrusions have a maximum protrusion height of less than ¼ of a dimple depth.
8. The golf ball of claim 2 , wherein a plurality of the linear protrusions have a protrusions length that is at least 5 times a width of the protrusion.
9. The golf ball of claim 2 , wherein the linear protrusions have a protrusion width that is substantially similar to a protrusion height.
10. The golf ball of claim 2 , wherein the linear protrusions have a protrusion width that is greater than a protrusion height and a length between adjacent linear protrusions is at least 2 times the protrusion width.
11. The golf ball of claim 1 , wherein the linear channels within a dimple are disposed at an angle of between about 10 and 90 degrees with respect to the linear channels of an adjacent dimple.
12. The golf ball of claim 11 , wherein linear channels are arranged at an angle of between about 30 and 90 degrees with respect to the linear channels of the adjacent dimple.
13. The golf ball of claim 2 , wherein the linear protrusions within a dimple are disposed at an angle of between about 10 and 90 degrees with respect to the linear protrusions of an adjacent dimple.
14. The golf ball of claim 13 , wherein linear protrusions are arranged at an angle of between about 30 and 90 degrees with respect to the linear protrusions of the adjacent dimple.
