    摘要： A golf ball (20) approaching zero land area is disclosed herein. The golf ball (20) has an innersphere (21) with a plurality of tubular projections (40). Each of the plurality of projections (40) has an apex (50) that extends to a height to conform with the 1.68 inches requirement for USGA approved golf balls. The tubular lattice pattern on the inner sphere (21) of the golf ball (20) of the present invention has interconnected projections (40) that form a plurality of hexagons and pentagons in the preferred embodiment. The preferred embodiment has a parting line (100) that alternates upward and downward along adjacent rows of hexagons.

    摘要： A golf club having a club head with a striking plate having a thickness in the range of 0.010 to 0.250 inches is disclosed herein. The club head may be composed of three pieces, a face, a sole and a crown. Each of the pieces may be composed of a titanium material. The striking plate of the club head may have an aspect ratio less than 1.7. The striking plate may also have concentric regions of thickness with the thickness portion in the center. The club head may be composed of a titanium material, have a volume in the range of 175 cubic centimeters to 400 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a string plate surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head may also have a coefficient of restitution greater than 0.8 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.
