Abstract

A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball, a channel extending across a portion of the sole, wherein the channel is recessed from adjacent surfaces of the sole, a void defined on the sole of the body, and/or at least one external rib connected to the cover and extending downward from the cover. The at least one external rib may include a first external rib and a second external rib wherein each external rib is connected to the cover and extends downward from the cover, such that the external ribs are positioned within the void.

Claims

1. A golf club head comprising:

a face having a striking surface configured for striking a ball;

a body connected to the face and extending rearwardly from the face, the body having a crown, a sole, a heel, and a toe;

a channel extending across a portion of the sole, wherein the channel is recessed from adjacent surfaces of the sole;

a void defined on the sole of the body, wherein the body comprises a first leg and a second leg extending rearwardly from a base portion of the body, with the void being defined between the first and second legs, and a cover extending between the first and second legs and defining a top of the void;

at least one external rib is connected to the cover and extending downward from the cover, such that the at least one rib is positioned within the void, wherein the at least one external rib further comprises an upper portion connected to the cover, a lower portion opposite the upper portion, wherein the lower portion has a width that is greater than a width of the upper portion of the rib and 2 to 3 times greater than the width of the upper portion; and

wherein the body and the face combine to define an internal cavity, with a top surface of the cover partially defining the internal cavity, such that a portion of the internal cavity is positioned between the cover and the crown.

2. The golf club head of claim 1, wherein the at least one external rib comprises a pair of external ribs.

3. The golf club head of claim 1, further comprising at least one internal rib connected to an internal portion of the body and extending into the internal cavity.

4. The golf club head of claim 3, wherein the at least one internal rib comprises at least one upper internal rib connected to an internal portion of the cover and connected to an internal portion of the crown.

5. The golf club head of claim 3, wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the channel.

6. The golf club head of claim 3, wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the cover.

7. The golf club head of claim 1, wherein the at least one external rib includes a vertical portion extending from the cover that tapers into a transverse portion at the lower portion of the at least one external rib.

8. The golf club head of claim 7, wherein the transverse portion forms a T-shaped cross-section.

9. The golf club head of claim 7, wherein the transverse portion forms a L-shaped cross-section.

10. A golf club head comprising:

a face having a striking surface configured for striking a ball;

a body connected to the face and extending rearwardly from the face, the body having a crown, a sole, a heel, and a toe;

an elongated channel extending across a portion of the sole in a heel to toe direction, wherein the channel is recessed from adjacent surfaces of the sole and has a depth of recession from the adjacent surfaces of the sole, wherein the channel comprises a center portion extending across a center of the sole, a heel portion extending from a heel end of the center portion toward the heel, and a toe portion extending from a toe end of the center portion toward the toe; and

a void defined on the sole of the body, wherein the body comprises a first leg and a second leg extending rearwardly from a base portion of the body, with the void being defined between the first and second legs, and a cover extending between the first and second legs and defining a top of the void; and

a first external rib and a second external rib wherein each external rib is connected to the cover and extends downward from the cover, such that the external ribs are positioned within the void, wherein each of the external ribs further comprise an upper portion connected to the cover, a lower portion opposite the upper portion, a front portion, a rear portion, and a central portion, wherein the lower portion of the first external rib has a first width and the upper portion of the first external rib has a second width, wherein the first width is greater than the second width, and wherein the lower portion of the second external rib has a third width and the upper portion of the second external rib has a fourth width, wherein the first width and the third width are substantially similar and wherein the second width and the fourth width are substantially similar; and

wherein the body and the face combine to define an internal cavity, with a top surface of the cover partially defining the internal cavity, such that a portion of the internal cavity is positioned between the cover and the crown.

11. The golf club head of claim 10, wherein the pair of external ribs diverge away from one another in a rear to front direction.

12. The golf club head of claim 10 wherein the cover further comprises a first wall and a second wall.

13. The golf club head of claim 12 wherein the first external rib is connected to the first wall of the cover and the second external rib is connected to the second wall of the cover.

14. The golf club head of claim 10 further comprising at least one internal rib connected to an internal portion of the body and extending into the internal cavity.

15. The golf club head of claim 14 wherein the at least one internal rib comprises at least one upper internal rib connected to an internal portion of the cover and connected to an internal portion of the crown.

16. The golf club head of claim 14 wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the channel.

17. The golf club head of claim 14 wherein the at least one internal rib comprises at least one lower internal rib connected to an internal portion of the sole and connected to an internal portion of the cover.
