Abstract
A golf ball with multi-lobed dimples is provided. The dimple comprises a plurality of lobes positioned radially around the center of the dimple, wherein each lobe is defined by a circumferential segment. Each lobe comprises a first curved profile extending from the circumferential segment toward the center of the dimple and the first curved profile of each lobe abuts each other in an uninterrupted manner. The curvature of the circumferential segments can be defined by a ratio of an inside radius to an outside radius.

A golf ball comprising:
- a substantially spherical outer surface;
- and
- a plurality of multi-lobed dimples formed on the outer surface of the ball, wherein the lobes in each dimple are positioned radially around the center of the dimple, wherein each lobe is defined by a circumferential segment and wherein said circumferential segment defines a part of the perimeter of the dimple, and wherein a prominence ratio of each multi-lobed dimple is defined by a ratio of an average of an inside radii extending from the center to troughs of the lobes to an average of an outside radii extending from the center to apex points of the lobes, and wherein the ratio is less than 1.0, and wherein the golf ball has a dimple coverage of more than about 90%.
A golf ball comprising:
- a substantially spherical outer surface;
- and
- a plurality of multi-lobed dimples formed on the outer surface of the ball, wherein the lobes in each dimple are positioned radially around the center of the dimple, wherein each lobe is defined by a circumferential segment and wherein said circumferential segment defines a part of the perimeter of the dimple, and wherein each lobe comprises a first curved profile extending from the circumferential segment toward the center of the dimple and wherein the first curved profiles of the lobes abut each other in an uninterrupted manner such that the curved profile of one lobe continuously and smoothly extends to and abuts with the curved profile of an opposite or near-opposite lobe, and wherein the golf ball has a dimple coverage of more than about 90%.
