Abstract
A golf ball approaching zero land area is disclosed herein. The golf ball has an innersphere with a plurality of pyramidal projections. Each of the plurality of projections has an apex that extends to a height to conform with the 1.68 inches requirement for USGA approved golf balls. The plurality of pyramidal projections extend 0.005 inches to 0.015 inches from the innersphere surface. The outermost 0.002 inches of the golf ball has a minimal volume.
Claims13
A golf ball comprising:
- an innersphere having a surface, the radius of the innersphere ranging from 0.825 inch to 0.840 inch;
- and
- a plurality of pyramidal projections disposed on the innersphere surface, each of the pyramidal projections extending from 0.005 inch to 0.015 inch from the innersphere surface, each of the pyramidal projections having three concave sides, a radius of curvature for each concave sides ranging from 0.225 inch to 0.300 inch.
A non-dimpled golf ball comprising:
- a sphere having a diameter in the range of 1.60 inch to 1.76 inch;
- a plurality of pyramidal projections extending outward from the sphere, each of the pyramidal projections having an apex that extends from a surface of the sphere in a range of 0.005 inch to 0.015 inch, each of the pyramidal projections having three or six concave sides, the radius of curvature of each of the concave sides ranging from 0.225 inch to 0.300 inch;
- and
- a plurality of smooth portions on the surface;
- wherein the entire surface of the golf ball is composed of the plurality of pyramidal projections and the plurality of smooth portions.
The non-dimpled golf ball according to claim 8 wherein the apex of each of the plurality of pyramidal projections has a width less than 0.00001 inches.
A golf ball comprising:
- a surface having a plurality of pyramidal projections thereon, each of the pyramidal projections having three or six concave sides, the radius of curvature of each of the concave sides ranging from 0.225 inch to 0.300 inch, wherein an apex of at least one the plurality of pyramidal projections defines the greatest extent of the golf ball, wherein the volume of the outermost 0.002 inch of the golf ball is less than 0.00213 cubic inches.
