Golf ball dimple surface

Abstract

Golf ball dimples having a surface defined by a mode, or a weighted superposition of multiple modes, of oscillation of an n-sided polygon shaped membrane are disclosed.

What is claimed is: 
     
         1 . A golf ball having a plurality of recessed dimples on the surface thereof, wherein at least a portion of the recessed dimples have a surface defined by a mode of oscillation of a n-sided polygon shaped membrane, wherein the membrane extends over a domain which fits inside a circumscribed circle having a diameter of from 0.005 inches to 0.350 inches. 
     
     
         2 . The golf ball of  claim 1 , wherein the n-sided polygon is a four-sided polygon. 
     
     
         3 . The golf ball of  claim 1 , wherein the n-sided polygon is an irregular polygon. 
     
     
         4 . The golf ball of  claim 1 , wherein the polygon is a regular polygon selected from the group consisting of triangles, squares, rectangles, pentagons, hexagons, heptagons, and octagons. 
     
     
         5 . The golf ball of  claim 1 , wherein the domain fits inside a circumscribed circle having a diameter of from 0.020 inches to 0.250 inches. 
     
     
         6 . The golf ball of  claim 1 , wherein the domain fits inside a circumscribed circle having a diameter of form 0.100 inches to 0.220 inches. 
     
     
         7 . The golf ball of  claim 1 , wherein the dimples having a surface defined by a mode of oscillation of a n-sided polygon shaped membrane have a chord depth of from 0.001 inches to 0.030 inches. 
     
     
         8 . The golf ball of  claim 1 , wherein the dimples having a surface defined by a mode of oscillation of a n-sided polygon shaped membrane have a chord depth of from 0.005 inches to 0.015 inches. 
     
     
         9 . The golf ball of  claim 1 , wherein the dimples having a surface defined by a mode of oscillation of a n-sided polygon shaped membrane have a chord depth of from 0.007 inches to 0.010 inches. 
     
     
         10 . The golf ball of  claim 1 , wherein the dimples having a surface defined by a mode of oscillation of a n-sided polygon shaped membrane have an edge angle of from 1° to 100°. 
     
     
         11 . The golf ball of  claim 1 , wherein the dimples having a surface defined by a mode of oscillation of a n-sided polygon shaped membrane have an edge angle of from 5° to 90°.
