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.
1. A non-circular dimple for a golf ball, comprising:
a bottom surface including multiple portions defined by a plurality of intersecting cylindrical surfaces, each of the multiple portions corresponding with one of the plurality of intersecting cylindrical surfaces, wherein the bottom surface contains a first bottom portion defined by a first cylinder having a first radius, a second bottom portion defined by a second cylinder having a second radius, and a third portion defined by a third cylinder having a third radius, each of the first cylinder, second cylinder and third cylinder having parallel axes and the first radius being greater than the second radius or the third radius.
2. A non-circular dimple according to claim 1 , wherein the second radius and the third radius are equal.
3. A non-circular dimple according to claim 2 , wherein the second cylinder and the third cylinder have axes contained in the same plane.
4. A golf ball having an outer surface containing a plurality of dimples, at least one of said dimples comprising:
a bottom surface including multiple portions defined by a plurality of intersecting cylindrical surfaces, each of the multiple portions corresponding with one of the plurality of intersecting cylindrical surfaces, wherein the bottom surface contains a first bottom portion defined by a first cylinder having a first radius, a second bottom portion defined by a second cylinder having a second radius, and a third portion defined by a third cylinder having a third radius, each of the first cylinder, second cylinder and third cylinder having parallel axes and the first radius being greater than the second radius or the third radius.
5. A golf ball comprising:
a surface, the surface comprising a plurality of dimples consisting of twelve dual radius penta-semicylinder dimples, fifty symmetric dual radius tri-cylinder dimples and two hundred sixty non-symmetric dual radius tri-cylinder dimples;
wherein the golf ball has 90% dimple surface coverage.
6. The golf ball according to claim 5 wherein each of the fifty symmetric dual radius tri-cylinder dimples has twelve dimple surfaces.
