1. A golf club head comprising:
- a face configured for striking a ball with an outer surface thereof;
a body connected to the face, the body adapted for connection of a shaft proximate a heel of the body and having a toe opposite the heel;
a first stiffening member extending rearward from an inner surface of the face and extending across the inner surface of the face between a first location and a second location, the first location positioned in an upper heel quadrant of the face, and the second location is positioned toward a lower toe quadrant of the face with respect to the first location, the first stiffening member providing locally increased stiffness to a first area of the face between the first location and the second location; and
a plurality of second stiffening members extending rearward from the inner surface of the face and combining to provide locally increased stiffness to a second area of the face spaced from the first area and located in an upper toe quadrant or a lower heel quadrant of the face, wherein the second stiffening members are arranged in a radiating formation, and wherein the second stiffening members of the radiating formation radiate from a point spaced from the center of the face,wherein the first stiffening member provides a greater degree of stiffness to the face than the combined second stiffening members, such that the second area of the face has greater flexibility than the first area.

Abstract
A ball striking device, such as a golf club head, has a head that includes a face configured for striking a ball and a body connected to the face, the body being adapted for connection of a shaft proximate a heel thereof. The face includes one or more stiffening members or other structures on the inner surface of the face to provide locally increased stiffness to particular areas of the face. Certain stiffening members may provide greater stiffness than other stiffening members, allowing the face to be configured for areas of greatest stiffness and greatest COR tailored to common impact patterns.
