Abstract

A golf club head is provided and includes a club head body, a club head face connected to a front portion of the club head body, wherein the club head face includes a club face surface having a plurality of face cavities arranged across the club face surface and a plurality of protrusion posts, wherein each of the plurality of protrusion posts includes a post body having a post base and a post head, wherein the plurality of protrusion posts is associated with the club face to extend away from the club face surface such that the post base of each of the plurality posts is located in separate cavities of the plurality of face cavities.

Claims

1. A golf club head, comprising:

a club head body; and

a club head face associated with a front portion of the club head body, wherein the club head face includes in the central, ball-striking portion thereof a plurality of cavities extending partially into the club head body, with each of the cavities terminating within the club head body;

wherein the club head face includes in the central, ball-striking portion thereof a plurality of protrusion posts and each of the plurality of protrusion posts includes a post body having a post base and a post head, wherein the plurality of protrusion posts is associated with the club head face to extend away from the surface of the club head face such that the post base of each of the plurality posts is associated with separate cavities of the plurality of cavities, at least some of the protrusion posts extending in a non-perpendicular fashion with respect to the surface of the club head face, the plurality of protrusion posts being spaced sufficiently close to each other to make contact with and impact a golf ball when the central portion of the club face strikes the ball.

2. The golf club head of claim 1, wherein the post base includes a base width BW and the face cavity includes a cavity width CW and wherein the base width BW and the cavity CW are sized to allow the post base to fit snugly within the face cavity.

3. The golf club head of claim 1, wherein the post base includes a base width BW and the post head includes a head width HW and wherein the base width BW and the head width HW are substantially equal.

4. The golf club head of claim 1, wherein the post head is configured in at least one of a round shape, square shape, a single pointed shape, a multi-pointed shape, a wedge shape, a star shape and a triangular shape.

5. The golf club head of claim 1, wherein the plurality of protrusion posts are securely associated with the club face via at least one of a friction fit, a weld or an epoxy.

6. The golf club head of claim 1, further comprising at least one sensing device associated with at least one of the plurality of protrusion posts.

7. The golf club head of claim 1, wherein the plurality of posts are associated with the plurality of cavities via at least one of a threaded connection, an epoxy and a friction/snap fit connection.

8. The golf club head of claim 7, wherein the plurality of posts are removably associated with the plurality of cavities.

9. The golf club head of claim 7, wherein the plurality of posts are of various lengths to extend out of the club head face at varying distances.

10. A golf club head, comprising:

a club head body; and

a club head face associated with a front portion of the club head body, wherein the club head face includes in the central, ball-striking portion thereof a plurality of cavities extending partially into the club head body, with each of the cavities terminating within the club head body;

wherein the club head face includes in the central, ball-striking portion thereof a plurality of protrusion posts and each of the plurality of protrusion posts includes a post body having a post base and a post head, wherein the plurality of protrusion posts is associated with the club head face to extend away from the surface of the club head face such that the post base of each of the plurality posts is associated with separate cavities of the plurality of cavities, the plurality of protrusion posts being of various lengths and extend out of the club head face at varying distances, the plurality of protrusion posts being spaced sufficiently close to each other to make contact with and impact a golf ball when the central portion of the club face strikes the ball.

11. The golf club head of claim 10, wherein the plurality of protrusion posts are integrally formed with the club head face.

12. The golf club head of claim 10, wherein the plurality of protrusion posts are removably associated with the club head face via at least one of a threaded connection, an epoxy and a friction/snap fit connection.

13. The golf club head of claim 12, wherein the protrusions protrusion posts include a protrusion base and a protrusion head and wherein the protrusion base includes a base width BW and the post head includes a head width HW and wherein the base width BW and the head width HW are substantially equal.

14. The golf club head of claim 12, wherein the protrusion head is configured in at least one of a round shape, square shape, a single pointed shape, a multi-pointed shape, a wedge shape, a star shape and a triangular shape.

15. The golf club head of claim 10, further comprising at least one sensing device associated with at least one of the plurality of protrusion posts.

16. A golf club head, comprising:

a club head body; and

a club head face associated with a front portion of the club head body, wherein the club head face includes in the central, ball-striking portion thereof a plurality of cavities extending partially into the club head body, with each of the cavities terminating within the club head body;

wherein the club head face includes in the central, ball-striking portion thereof a plurality of protrusion posts and each of the plurality of protrusion posts includes a post body having a post base and a post head, wherein the plurality of protrusion posts is associated with the club head face to extend away from the surface of the club head face such that the post base of each of the plurality posts is associated with separate cavities of the plurality of cavities, at least one sensing device being associated with at least one of the plurality of protrusion posts, the plurality of protrusion posts being spaced sufficiently close to each other to make contact with and impact a golf ball when the central portion of the club face strikes the ball.
