A finished, painted golf ball is disclosed. Dimples on the golf ball are interrelated by dimple number, dimple diameter and dimple depth and are arranged on the surface of the golf ball in a manner which enables the golf ball to travel further. At least about 80% of the distances between the closest points of the edges of adjacent dimples are less than about 0.065 inches and at least about 55% of the distances between the closest points of the edges of adjacent dimples are greater than about 0.001 inches. Dimple number, dimple diameter and dimple depth are also interrelated in a specific manner according to the formula: ##EQU1## wherein: d=average depth of all dimples in inches D=average diameter of all dimples in inches S=computed unknown (1.0 or less for present invention) x, y, a and b are dependent on the number of dimples.
A finished, painted golf ball which has from about 182 to about 392 dimples in the outer periphery thereof, the placement of the dimples being such that at least about 80% of the distances between the closest points of the edges of adjacent dimples is less than about 0.065 inches, and at least about 55% of the distances between the closest points of the edges of adjacent dimples is greater than about 0.001 inches, the edge of the dimple being defined as the point of intersection of the periphery of the golf ball or its continuation and a tangent to the sidewall of the dimple at a point 0.003 inches below the periphery of the golf ball or its continuation, and wherein combinations of the diameter D and depth d of all dimples formed on the ball are defined by the relationship:
A finished, painted golf ball having from about 182 to 332 dimples, the depth, diameter and number of dimples being defined by the relationship:
A finished, painted golf ball having from about 182 to about 332 dimples, the depth, diameter and number of dimples being defined by the relationship:
A finished, painted golf ball having from about 315 to about 340 dimples, the depth and diameter of the dimples being defined by the relationship:
A finished, painted golf ball having on the surface thereof from about 315 to about 340 dimples, each said dimple being a section of a sphere, each said dimple having a diameter of about 0.150 inches and a depth of about 0.0125 inches, the dimples being arranged on the surface of the golf ball in the pattern of an icosahedron and the placement of the dimples being such that 100% of the distances between the closest points of the edges of adjacent dimples is greater than about 0.001 inches and less than about 0.065 inches.
A finished, painted golf ball having from about 333 to about 392 dimples, the depth, diameter and number of dimples being defined by the relationship:
