Abstract

The invention provides a golf club head having a port for providing a view into the interior cavity of the club head. The club head further includes at least one rib positioned along an internal surface of the club head and adjacent to the port. The at least one rib is configured to provide sound tuning characteristics, increasing the frequency of the port, thereby improving acoustic properties of the club head, particularly the sound produced by the golf club head during ball impact.

Claims

1. A golf club head comprising:

a club head body comprising a heel, a toe, a sole, a crown, and a ball-striking face; and

at least one port coupled to a portion of the club head body and configured to provide a view from the exterior of the club head into an interior cavity of the club head body.

2. The golf club head of claim 1, further comprising at least one rib positioned on an internal surface of the interior cavity of the club head and having at least a first end adjacent to the port.

3. The golf club head of claim 2, wherein the at least one rib is configured to provide sound tuning characteristics for the golf club head.

4. The golf club head of claim 3, wherein the at least one rib is configured to increase a vibration frequency value of an area adjacent the port to improve an acoustic property of the club head.

5. The golf club head of claim 4, wherein the acoustic property is a sound produced by the golf club head during impact between the ball-striking face and a ball.

6. The golf club head of claim 1, wherein the at least one port comprises a body portion and a window portion.

7. The golf club head of claim 6, wherein the body portion comprises:

an inner annular wall; and

an outer annular wall surrounding the inner annular wall.

8. The golf club head of claim 7, wherein the outer annular wall has a threaded external surface configured to engage an internally threaded mounting portion on the club head body.

9. The golf club head of claim 8, wherein mounting portion is on the sole of the club head body.

10. The golf club head of claim 6, wherein the window portion lies within and is surrounded by the inner annular wall, the window portion comprising a transparent or translucent material configured to provide a view into the interior cavity of the club head body.

11. The golf club head of claim 1, wherein the interior cavity includes at least one feature selected from the group consisting of:

a mass adjustment mechanism configured for adjusting a mass distribution of the club head body;

a sound tuning member for adjusting sound properties of the club head;

informative data provided in the form of a painting, marking, indicia, engraving, embossing, and decal; and

one or more electronic devices positioned within the club head body for collecting information related to the club head body and/or club head performance.

12. A golf club head comprising:

a club head body comprising a heel, a toe, a sole, a crown, and a ball-striking face; and

at least one port coupled to a mounting portion on the sole of the club head body, the at least one port comprising;

a body portion having an inner annular wall and an outer annular wall surrounding the inner annular wall; and

a window portion comprising a transparent or translucent material configured to provide a view from the exterior of the club head into an interior cavity of the club head body; and

at least a first rib positioned on an internal surface of the sole and extending from the port towards a perimeter of the club head body.

13. The golf club head of claim 12, wherein the first rib extends from the port towards a portion of the face adjacent to the toe of the club head body and a second rib extends from the port towards a portion of the face adjacent to the heel of the club head body.

14. The golf club head of claim 13, wherein the first and second ribs radiate from the outer annular wall of the port, defining an angle there between.

15. The golf club head of claim 14, wherein the angle between the first and second ribs is in the range of 10 degrees and 170 degrees.

16. The golf club head of claim 15, wherein the angle between the first and second ribs is in the range of 45 degrees and 135 degrees.

17. The golf club head of claim 16, wherein the angle between the first and second ribs is 90 degrees.

18. The golf club head of claim 13, wherein the first and second ribs are aligned in a converging configuration.

19. The golf club head of claim 12, wherein the first rib is configured to provide sound tuning characteristics for the golf club head.

20. The golf club head of claim 20, wherein the first rib is configured to increase a vibration frequency value of an area adjacent the port to improve an acoustic property of the club head.
