Abstract:
1. A golf club head comprising: a crown portion, a sole portion, and a striking surface having a face center, a center apex, and a top edge; a hosel having a hosel centerline, wherein the club head is oriented relative to an imaginary horizontal ground plane so that the hosel centerline is in an imaginary vertical plane generally parallel to the top edge of the strike face and is at an angle of 60° relative to the imaginary horizontal ground plane; a furthest rearwardly projecting point; an overall length defined by the shortest horizontal distance between an imaginary front vertical plane, generally parallel to the top edge and passing through the center apex, and an imaginary rear vertical plane that is parallel to the front vertical plane and passes through the furthest rearwardly projecting point of the club head; a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant, each defined by an imaginary longitudinal vertical plane, substantially perpendicular to the striking surface and passing through the face center, and an imaginary transverse vertical plane, orthogonal to the imaginary longitudinal vertical plane and bisecting the club head at one-half the overall length; and a linear stiffening element coupled to the sole portion and not the crown portion, the stiffening element disposed in at least three of the four quadrants at an angle between 50° and 85° to an imaginary vertical plane oriented substantially perpendicular to the striking surface and containing the face center.
