METAL WOOD CLUB WITH IMPROVED MOMENT OF INERTIA

摘要

A more efficient triangular shape for metal wood clubs or driver clubs is disclosed. This triangular shape allows the clubs to have higher rotational moments of inertia in both the vertical and horizontal directions, and a lower center of gravity.

1. A golf club head comprising:
a hitting face at a frontal portion of said golf club head; an aft portion; and a midsection connecting said hitting face to said aft portion; wherein said aft portion defines an aft wall length that is approximately 30% to about 50% of a length of said hitting face, said aft wall length defined as the longest distance of said aft portion measured in a heel to toe direction viewed from a top view of said golf club head, and wherein said golf; club head has a moment of inertia Ixx, about a horizontal axis through a center of gravity of said golf club head of about 200 g·cm2 to about 4500 g·cm2, and a moment of inertia, Iyy about a vertical axis through said center of gravity of said golf club head of about 400 g·cm2 to about 5900 g·cm2.
