Dimples comprised of two or more intersecting surfaces
A golf ball with a dimple pattern designed to maximize flight characteristics employs dimples which are created by joining two or more intersecting surfaces. The invention provides for single radius or dual radius dimples, preferably including smaller radius cylinders tangentially arranged along the side of the larger cylinders. The intersection of the cylinders forms tri-cylinders, tri-semicylinders, bi-cylinders, quad-semicylinders, penta-semicylinders, or more generally n-cylinders depending upon the number of intersecting cylinders. The golf ball includes a plurality of single or dual radius dimples created by intersecting n-cylinders to create maximum turbulence on the ball during flight.
