Abstract
A golf ball includes an outer land surface and a plurality of dimples formed thereon. The dimples comprise structures of its surface to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. These structures may include sub-dimples arranged in various configurations on the dimple. The sub-dimples may have various sizes and shapes. The structures may also include radiating concave or convex arms emanating from the center or a location proximate the center of the dimple. The radiating arms may have various sizes and shapes and may protrude beyond the dimples. By improving the aerodynamic of the airflow over the dimpled surface of the golf ball, the outer land surface of the golf ball may remain robust to prevent premature wear and tear on the golf ball.
Claims27
A golf ball comprising:
- a substantially spherical outer surface;
- and
- a plurality of dimples formed on the outer surface of the ball, said dimples comprising a perimeter and an inner surface therebetween, wherein a plurality of the dimples comprise a plurality of sub-dimples formed on the dimple inner surface whereby a boundary layer of air flowing over the surface of the dimples is energized.
A golf ball comprising
- a substantially spherical outer surface;
- and
- a plurality of dimples formed on the outer surface of the ball, said dimples having a perimeter, an inner surface, and a center,
- wherein at least one of the dimples comprises a plurality of radiating arms emanating from a location proximate the center of the dimple to energize a boundary layer of air flowing over the dimple.
