Abstract
Golf ball dimples having a cross-sectional profile shape defined by the product of a base profile and one or more weighting functions are disclosed.
Claims22
A golf ball having a plurality of recessed dimples on the surface thereof, wherein at least a portion of the recessed dimples have a non-spherical cross-sectional profile and a chord depth range from 0.006 inches to 0.016 inches, where the non-spherical cross-sectional profile is defined by a weighted function, wherein the weighted function is the multiplication of a spherical base profile function g(x) and at least one weighting function w(x) selected from the group consisting of polynomial, exponential, and trigonometric functions, the weighted function resulting in a non-spherical cross-sectional weighted dimple profile different from the base dimple profile,
- wherein the base dimple profile is modified using a profile relative method, wherein
- f(x)=g(x)*(1+w(x))
- wherein the weighting function w(x) is continuous and applied from the dimple center at x=0 to the dimple perimeter at x=d/2 where d is the dimple diameter, and g(x) and f(x) are equal at x=d/2.

- wherein the base dimple profile is modified using a pure weighting method, wherein
- f(x)=g(x)*(w(x))
- wherein the weighting function w(x) is continuous and applied from the dimple center at x=0 to the dimple perimeter at x=d/2 where d is the dimple diameter, and g(x) and f(x) are equal at x=d/2.
