Golf ball with dimple pattern having depth progression
View Patent ↗A golf ball with superior aerodynamic properties is characterized by a progressive depth of dimples on the surface of the ball. The ball surface is divided into a plurality of equal geometries such as triangles, each of which is filled with a plurality of non-overlapping dimples. Groups of dimples are provided in each geometry, the dimples of each group having different depths, respectively. A first group of dimples is arranged about the perimeter of the geometry and a second group of dimples is arranged within the first group. A third group of dimples having a third depth may be provided within the second group, with the depth of the third group being less than the depth of the second group which is less than the depth of the first group. Alternatively, the depth of the third group is greater than the depth of the second group which is greater than the depth of the first group. Similarly, the first and third groups may have the same depth but different from the second group.
1. A golf ball having a spherical surface, comprising
(a) a pattern defined on the golf ball surface, said pattern including a plurality of geometries;
(b) a plurality of dimples arranged in said geometries, respectively, said dimples comprising at least two groups of dimples, a first group of dimples having a first depth and being arranged adjacent to a portion of the perimeter of said geometries and a second group of dimples having a second depth different from said first depth and being arranged within said first group of dimples, said first and second depths being independent of a width of dimples of said first and second groups of dimples, respectively, whereby the golf ball has improved aerodynamic properties, and further comprising a third group of dimples having a third depth different from said second depth and independent of the width of dimples of said third group of dimples, said third group of dimples being arranged within said second group of dimples, whereby a depth progression of dimples is provided within each geometry, and wherein said third depth is less than said second depth which is less than said first depth.
