GOLF CLUB HEAD
First Claim
1. A golf club head comprising:
- a strike face;
a top portion coupled to the strike face;
a bottom portion coupled to the strike face;
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 a first imaginary vertical plane generally parallel to the strike face, the hosel centerline oriented at an angle of 60°
relative to the imaginary horizontal ground plane in the first imaginary vertical plane;
a discrete stiffening element coupled to at least one of the top portion and the bottom portion, the discrete stiffening element being at least partially curvilinear and comprising generally vertical side surfaces; and
a path characterized by the vertical projection of one of the generally vertical side surfaces onto one of the bottom portion and the top portion, wherein the path has at least two inflection points.

Abstract
A golf club head according to one or more aspects of the present invention may generally include a strike face, a top portion, a bottom portion, a heel portion, a toe portion, and a hosel having a central axis located in a first imaginary vertical plane. A discrete, at least partially curvilinear stiffening element, having generally vertical side surfaces, may be coupled to at least one of the top portion and the bottom portion to improve the dynamic-excitation response of the club head. Preferably, the stiffening element is oriented such that an imaginary horizontal line intersects at least one of the vertical surfaces at at least two points. Additionally, the stiffening element may have at least two inflection points located along a non-linear path characterized by the vertical projection of one of the side surfaces onto at least one of the bottom portion and the top portion of the club head.
