Title:
GOLF CLUB HEAD
Document Type and Number:
Japanese Patent JPH0947528
Kind Code:
A
Abstract:

To stabilize the direction of a bit ball and to prevent decline of the carry, by embedding a weight into a heel side and a toe side toward a face opposite to a club face, so that the position of the center of gravity of a wood club head is lowered and a torsion becomes hard to occur.

Weights 40 are embedded into a golf club head on the heel side and the toe side on the face opposite to the club face 10. In such a golf club head, the position of the center of gravity A1 is deeper than the center of gravity A2 of a convertional golf club head as shown by an imaginary line. Consequently, due to inertia, even when, for example, a hitting position of a ball is off the sweet spot to be on the toe side, the twist angle becomes θ1 which is smaller than the conventional twist angle θ2, resulting in less deviation in directionality. At the same time, even when the hitting position of the ball is off the sweet spot, the position of the center of gravity is far, twist hardly occurs, so that an impact force lowers little, and the carry declines very little.
