Abstract
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 a plurality of the dimples incorporate directional surface texturing therein. The directional surface texturing preferably comprises substantially parallel channels or protrusions formed within the dimples. The directional surface texturing can comprise of parallel linear channels or protrusions or parallel non-linear linear channels or protrusions.
Claims18
A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least one of the dimples incorporates non-linear directional surface texturing comprised of 2 or more substantially parallel, non-linear channels that have an arc radius (ar) and the arcs span less than 180 degrees.
A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least one of the dimples incorporates non-linear directional surface texturing comprised of 2 or more substantially parallel, non-linear channels, wherein the at least one dimple has a dimple diameter (D) and the non-linear channels are separated by a parallel distance (Dp) such that Dp<⅓D, wherein a plurality of dimples comprise non-linear directional surface texturing and each dimple having non-linear directional surface texturing has no adjacent dimples with non-linear directional surface texturing.
A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least one of the dimples incorporates non-linear directional surface texturing comprised of 2 or more substantially parallel, non-linear channels, wherein the at least one dimple has a dimple diameter (D) and the non-linear channels are separated by a parallel distance (Dp) such that Dp<⅓D, wherein each dimple having non-linear directional surface texturing has at least one adjacent dimple with non-linear directional surface texturing, wherein a plurality of dimples having non-linear directional surface texturing have an adjacent dimple with non-linear directional surface texturing, wherein the dimples have mirror symmetry of each other about a midline separating the dimples.
A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least one of the dimples incorporates non-linear directional surface texturing comprised of 2 or more substantially parallel, non-linear channels, wherein the at least one dimple has a dimple diameter (D) and the non-linear channels are separated by a parallel distance (Dp) such that Dp<⅓D, wherein each dimple having non-linear directional surface texturing has at least one adjacent dimple with non-linear directional surface texturing, wherein a plurality of dimple having non-linear directional surface texturing have two adjacent dimples with non-linear directional surface texturing, wherein the dimples are rotationally symmetric about a centroid of the dimples.
A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least one of the dimples incorporates non-linear directional surface texturing comprised of 2 or more substantially parallel, non-linear channels, wherein a plurality of dimples comprise non-linear directional surface texturing and each dimple incorporating non-linear directional surface texturing is circular in plan shape and has a dimple diameter of 0.11 inch to 0.22 inch and the non-linear channels have a channel radius of 0.01 inch to 0.08 inch and a channel depth of 0.0003 inch to 0.003 inch.
