Abstract

A ball striking device, such as a golf club head, includes a face having a ball striking surface configured for striking a ball and a body connected to the face and extending rearwardly from the face. The body has an impact-influencing structure in the form of a channel positioned on at least one surface of the body. A majority of a force generated by impact with a ball is absorbed by the impact-influencing structure, and a majority of a response force generated by the head upon impact with the ball is generated by the impact-influencing structure. The face may have increased stiffness as compared to existing faces, and may include a stiffening structure to create the increased stiffness, such as a porous or cellular stiffening structure.

12. The golf club head of claim 2, further comprising:

a toe channel located on the surface of the body, the toe channel having a third periphery defined by third boundary edges, wherein the toe channel is located between the toe side of the body and the geometric centerline of the body,

wherein the boundary edges of the first channel and the third boundary edges of the toe channel are disconnected and separated from each other by a toe spacing portion separating the first channel from the toe channel.

13. The golf club head of claim 12, wherein the toe spacing portion extends toward the face and toward the toe side of the body in a direction that is angled with respect to the geometric centerline of the body.

14. The golf club head of claim 2, wherein the heel portion and the toe portion of the rear edge are also angled with respect to the geometric centerline of the body.

15. A golf club head comprising:

a face having a ball striking surface and being defined by a peripheral edge;

a body connected to the face and extending rearward from the face to define an enclosed volume, the body having a front side, a rear side, a heel side, a toe side, a crown, and a sole;

a center recess located on a surface of the body, the center recess having a first periphery defined by first boundary edges, wherein the center recess extends between a heel end and a toe end located on opposite sides of a geometric centerline of the body;

a heel recess located on the surface of the body and located between the heel side of the body and the geometric centerline of the body, the heel recess having a second periphery defined by second boundary edges; and

a toe recess located on the surface of the body and located between the toe side of the body and the geometric centerline of the body, the heel recess having a third periphery defined by third boundary edges,

wherein the first boundary edges of the center recess and the second boundary edges of the heel recess are disconnected and separated from each other by a heel spacing portion separating the center recess from the heel recess, and
