<p><P>PROBLEM TO BE SOLVED: To provide an art for reducing the weight of a golf club head. <P>SOLUTION: This golf club head is provided with a crown having an aperture with an arcuate rear edge and a forward edge that is substantially parallel to the striking face. The aperture is transacted by an arcuate rib that extends from a region proximal the heel end of the crown to a region proximal the toe end of the crown and is concave toward the striking face. A pair of linear ribs extends radially outward from the arcuate rib to join the arcuate rib to a perimeter region of the crown. Openings formed in the aperture by the ribs are filled with an organic-composite material such as graphite epoxy. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
