Abstract
A golf club head including a striking face and a periphery portion surrounding and extending rearwards from the striking face. The golf club head includes at least one weight member having a particular shape to achieve a target center of gravity projection and also increase the moment of inertia.
Claims20
A golf club head comprising:
- a striking face having a front surface configured to strike a golf ball and a rear surface opposite said front surface;
- a periphery portion extending rearward from said striking face and including a sole, a topline opposite said sole, a heel side, and a toe side opposite said heel side;
- a hosel configured to receive a shaft, said hosel located on said heel side;
- a first weight member positioned proximate said toe side;
- and
- a coordinate system centered at a face center of said striking face,
- wherein said coordinate system has a y-axis extending vertically, perpendicular to a ground plane when said golf club head is in an address position at a prescribed loft angle and a prescribed lie angle;
- an x-axis perpendicular to said y-axis and parallel to said striking face, extending towards said heel side of said golf club head;
- and a z-axis, perpendicular to said y-axis and said x-axis and extending through said striking face,
- wherein said first weight member has an upper surface which is angled with respect to said ground plane in an x-y plane such that said first weight member has a maximum height in a sole-to-topline direction at a toewardmost point and a minimum height in said sole-to-topline direction at a heelwardmost point, and
- wherein said first weight member has a density between 10 g/cc and 15 g/cc.

A method of making a golf club head comprising:
- providing a striking face having a front surface configured to strike a golf ball and a rear surface opposite said front surface;
- providing a periphery portion extending rearward from said striking face and including a sole, a topline opposite said sole, a heel side, and a toe side opposite said heel side;
- providing a hosel configured to receive a shaft, said hosel located on said heel side;
- positioning a first weight member proximate said toe side;
- and
- defining a coordinate system centered at a face center of said striking face,
- wherein said coordinate system has a y-axis extending vertically, perpendicular to a ground plane when said golf club head is in an address position at a prescribed loft angle and a prescribed lie angle;
- an x-axis perpendicular to said y-axis and parallel to said striking face, extending towards said heel side of said golf club head;
- and a z-axis, perpendicular to said y-axis and said x-axis and extending through said striking face,
- wherein said first weight member has an upper surface which is within 20 degrees of perpendicular to said front surface of said striking face in a y-z plane, and
- wherein said first weight member has a density between 10 g/cc and 15 g/cc.
