Abstract

A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, and a channel located in the body. The channel is configured to influence the characteristics of the impact of a ball on the face, such as by flexing or compressing in response to the force of the impact, exerting a response or reaction force on the face, changing the motion or behavior of the face, and other manners. The head may also include a pair of channels that have a gap between them.

a first inwardly recessed channel and a second inwardly recessed channel located on the body and being configured to influence the impact of a ball on the face, the first channel being elongated along a direction of elongation that is generally parallel to at least one of the peripheral edges of the face between a first end and a second end, and the second channel also being elongated along a direction of elongation that is generally parallel to at least one peripheral edge of the face between a first end and a second end,

wherein each of the first and second channels includes a front edge, a rear edge and side walls extending inwardly into the body from the front and rear edges, and wherein the side walls of each of the first and second channels extend into the interior cavity and create a raised portion on an internal surface of the body, and

wherein a gap is defined between the first end of the first channel and the first end of the second channel.

10. The golf club head of claim 9, wherein first and second channels are configured to flex and compress upon impact of the ball on the face, and the channels are further configured to exert a response force on the face upon impact of the ball on the face and to force a bottom edge of the face outwardly upon impact of the ball on the face.

11. The golf club head of claim 9, wherein at least a portion of the first channel and at least a portion of the second channel are located on the sole, and at least a portion of the gap is located proximate a center of the sole.

12. The golf club head of claim 9, wherein the first channel and the second channel each have at least a portion that is elongated along a direction of elongation generally parallel to a bottom peripheral edge of the face and is spaced rearwardly from the bottom peripheral edge of the face.

13. The golf club head of claim 9, wherein each of the first and second channels is defined by a boundary edge, and each of the first and second channels is recessed from the boundary edge thereof.

14. A golf club comprising the golf club head of claim 9 and a shaft connected to the golf club head.

15. A golf club head comprising:

a face having an outer surface configured for striking a ball and defined by a plurality of peripheral edges;
