Patent Images
1. A golf club head for a wood type golf club, said club head comprising:
- a center of gravity;
an orthogonal reference point at the center of gravity, formed by three axes about which the inertia is maximum, wherein two of the three axes are located in a plane which is inclined with respect to the plane of the ground when the club head rests on the ground, the two axes forming with the plane of the ground, a dihedron having an internal angle comprised between 20 and 60 degrees;
said club head further including weight means for weighting the club head and for maximizing the inertia.

Abstract
The head of a golf club, preferably of the "wood" type, wherein the orthogonal reference passing through the center of gravity of the club head and formed by three axes about which the inertia is maximum, is such that the first two axes are located in a plane inclined with respect to the plane of the ground when the head rests on the ground, forming with the plane of the ground, a dihedron having an internal angle comprised between 20 and 60 degrees and/or wherein the axis forms with the vertical plane of the shot, an angle of between 20 and 60 degrees.

44. A golf club head comprising:
a body having a predeterminate distribution of mass, including a center of gravity (G), said body further comprising; a front portion, said front portion having a hitting surface (2); and a shot plane (T) extending, during impact with a golf ball during a shot, generally symmetrically through said body and extending frontwardly through said hitting surface (2) and generally perpendicularly with respect to said hitting surface (2) and with respect to a ground plane (S); an orthogonal reference point at the center of gravity (G), the reference point being formed by three orthogonal axes (X-X'"'"', Y-Y'"'"', Z-Z'"'"') about each of said axes the inertia of the body is maximum, and said three axes being situated in at least one of the following relationships; (1) two of the three axes (X-X'"'"', Y-Y'"'"', Z-Z'"'"') being located in a plane (P1 or P2) which is inclined with respect to the ground plane (S), the two axes forming, with the plane of the ground, a dihedron having an internal angle comprised between 20 and 60 degrees; and (2) one of the three axes (X-X'"'"', Y-Y'"'"', Z-Z'"'"') forming, with said shot plane (T), an angle comprised between 20 and 60 degrees.
