Golf ball dimples
View Patent ↗A multi-lobed golf ball dimple 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 and may be further defined by spoke-like ridges. 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 multi-lobed dimple may include uniform and non-uniform dimples. The curvature of the circumferential segments can be defined by a ratio of an inside radius to an outside radius. Each dimple also includes a slightly convex floor that is continuous and smooth. The curvature may match that of the outer surface of the golf ball. Further, a sloped wall interrupted by spoke-like ridges may connect the convex floor with the outer surface of the golf ball.
1. A golf ball comprising:
a substantially spherical outer land surface; and
a plurality of dimples formed on the outer land surface of the ball, wherein at least one of the dimples comprises a convex floor and a plurality of lobes positioned radially around the center of the dimple, wherein each lobe comprises a circumferential segment delineating a part of the perimeter of the dimple and a wall joining the circumferential segment with the convex floor,
wherein one of the lobes has a first wall configuration that differs from a second wall configuration of at least one of the remaining lobes.
2. The golf ball of claim 1 , wherein the convex floor is a substantially smooth and continuous spherical surface.
3. The golf ball of claim 2 , wherein the convex floor is concentric with the outer surface of the golf ball.
