Abstract
The present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the selection of the plan shapes of the dimples thereon. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a plan shape defined by a low frequency periodic function mapped along a simple closed path. In addition, the present invention provides methods for designing dimples having a plan shape defined by a low frequency periodic function mapped along a simple closed path.
Claims9
A golf ball having a generally spherical surface and comprising a plurality of dimples on the spherical surface, wherein at least a portion of the dimples are non-circular plan shape dimples having a plan shape defined by a periodic function mapped along a simple closed path, wherein the periodic function is selected from sine, cosine, sawtooth wave, triangle wave, and square wave functions, the simple closed path is selected from a circle, an ellipse, and a square;
- and the periodic function has a period of less than 6.
