Abstract
In accordance with the present invention, a golf ball includes an outer surface and a plurality of dimples formed thereon. At least one of the dimples is a concentric ring dimple. Each concentric ring dimple includes a central depression, and at least one annular depression that concentrically surrounds the central depression. A land ring extends between the central depression and the annular depression. When the concentric ring dimple includes additional annular depressions, land rings extend between the adjacent annular depressions. The concentric ring dimples provide additional dimple circumference over conventional dimples that occupy the same space, thereby improving the aerodynamic performance of the golf ball.
Claims24
A golf ball comprising:
- a) a substantially spherical outer surface;
- and b) a plurality of dimples formed on the outer surface, at least three of a first type of dimple including
- i. a central depression having a central depression diameter;
- ii. an annular depression concentrically surrounding the central depression and having an annular depression width;
- and
- iii. a land ring extending between the central depression and the annular depression, the land ring making Up a portion of the outer surface and having a land ring width;
- wherein the land ring width is substantially less than the annular depression width.
A golf ball comprising:
- a) a substantially spherical outer surface;
- and
- b) a plurality of dimples formed on the outer surface, at least three of a first type of dimple including
- i. a central, single depression having a central depression diameter;
- ii. at least two annular depressions concentrically surrounding the central depression and having annular depression widths;
- and
- iii. a plurality of land rings, one land ring making up a portion of the outer surface and extending between said central depression and said adjacent annular depression, other land rings making up a portion of the outer surface and extending between each of said adjacent annular depressions, and each land ring having a land ring width.
A golf ball comprising:
- a) a substantially spherical outer surface;
- and
- b) a plurality of dimples formed on the outer surface, at least three of a first type of dimple including
- i. a central depression having a central depression depth;
- ii. at least one annular depression concentrically surrounding the central depression and having an annular depression depth and an annular depression width;
- and
- iii. a plurality of land rings, one land ring making up a portion of the outer surface and extending between said central depression and said adjacent annullar depression, and land rings making up a portion of the outer surface and extending between each of said adjacent annular depressions;
- wherein the central depression depth is greater than or equal to the annular depression depth and the land ring width is substantially less than the annular depression width.
A golf ball comprising:
- a) a substantially spherical, outer surface;
- and
- b) a plurality of dimples formed on the outer surface, at least three of a first type of dimple including
- i. a central depression having a central depression edge angle;
- ii. at least one annular depression concentrically surrounding the central depression and having an inner annular depression edge angle and an outer annular depression edge angle;
- and
- iii. a plurality of land rings, one land ring making up a portion of the outer surface and extending between said central depression and said adjacent annular depression, and other land rings making up a portion of the outer surface and extending between each of said adjacent annular depressions;
- wherein the central depression edge angle and the annular depression edge angles are approximately equal and the land ring width is substantially less than the annular depression width.
