Golf Club Heads or Other Ball Striking Devices Having Distributed Impact Response
First Claim
1. A ball striking device comprising:
- a face having a ball striking surface configured for striking a ball;
a body connected to the face and extending rearwardly from the face, the body having an impact-influencing structure positioned adjacent at least one peripheral edge of the face, wherein at least a portion of a force generated by impact with a ball is absorbed by the impact-influencing structure, and at least a portion of a response force generated by the head upon impact with the ball is generated by the impact-influencing structure,wherein the face has a stiffness proximate a geometric center of the face that is from about 4,600-5,600 lb-in2.

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 positioned adjacent at least one peripheral edge of the face. 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. In one embodiment, the face may have a stiffness proximate the geometric center that is from about 4,600-5,600 lb-in2.

12. A ball striking device comprising:
-
a face having a ball striking surface and being defined by a plurality of face edges; a body connected to the face and extending rearward from the face edges to define an enclosed volume, wherein the body has a heel side, a toe side, a crown, and a sole; a channel defined on the body by first and second boundary edges extending continuously around an entire circumference of the body and generally equidistant from the face edges, the channel being recessed from outer surfaces of the body between the first and second annular boundary edges, the channel including a crown channel portion extending at least partially across the crown, a sole channel portion extending at least partially across the sole, and additional channel portions extending around the heel and the toe sides to interconnect the crown channel portion and the sole channel portion to form the channel in a continuous shape, wherein the channel is spaced rearwardly from the face edges by a spacing portion, and wherein the channel is configured such that at least some energy from an impact on the ball striking surface is transferred through the spacing portion and absorbed by the channel, causing the channel to deform and to exert a response force on the face. - View Dependent Claims (13, 14, 15, 16)

17. A ball striking device comprising:
-
a face having a ball striking surface and being defined by a plurality of face edges; a body connected to the face and extending rearward from the face edges to define an enclosed volume, wherein the body has a heel side, a toe side, a crown, and a sole; a first channel defined on the body by first and second boundary edges extending between a first end proximate the heel side and a second end proximate the toe side, the first channel extending at least partially across the crown of the body, wherein the first channel is recessed inwardly from outer surfaces of the body between the first and second edges; a second channel defined on the body by third and fourth boundary edges extending between a third end proximate the heel side and a fourth end proximate the toe side, the second channel extending at least partially across the sole of the body, wherein the second channel is recessed inwardly from the outer surfaces of the body between the third and fourth edges; wherein the first end is spaced from the third end, and the second end is spaced from the fourth end, such that the first channel and the second channel are completely separate, wherein the first and second channels are spaced rearwardly from the face edges by spacing portions, and wherein the first and second channels are configured such that at least some energy from an impact on the ball striking surface is transferred through the spacing portion and absorbed by at least one of the first and second channels, causing the at least one of the first and second channels to deform and to exert a response force on the face. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A ball striking device comprising:
-
a face having a ball striking surface and being defined by a plurality of face edges; a body connected to the face and extending rearward from the face edges to define an enclosed volume, wherein the body has a heel side, a toe side, a crown, and a sole; a band of flexible material extending around at least a portion of a circumference of the body and being generally equidistant from the face edges, the flexible material having a stiffness that is lower than a stiffness of the face and a modulus that is lower than a modulus of another portion of the body, wherein the band is configured such that at least some energy from an impact on the ball striking surface is transferred through the spacing portion and absorbed by the band, causing the band to deform and to exert a response force on the face. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39)
