Abstract

Disclosed herein is a golf club head comprising a body, at least one weight assembly, and at least one brace bar. The body defines an interior cavity and a face portion at the forward region of the body and comprising a strike face with an area of at least 3000 mm^2 and a maximum height from a ground plane of at least about 50 mm. The body further comprises at least one weight track formed in the sole portion. The at least one weight assembly is selectively adjustably positioned within the at least one weight track. The at least one brace bar traverses the interior cavity between and is attached to the at least one weight track and the crown portion. A mass per unit length of the brace bar is between 0.005 g/mm and 0.40 g/mm.

First claim

What is claimed is:

1. A golf club head, comprising:
a body, defining an interior cavity and comprising:
a sole portion, positioned at a bottom portion of the golf club head;
a crown portion, positioned at a top portion of the golf club head;
a skirt portion, positioned around a periphery of the golf club head between the sole portion and the crown portion;
a forward region;
a rearward region;
a face portion, at the forward region of the body and comprising a strike face with an area of at least 3000 mm^2 and a maximum height from a ground plane of at least about 50 mm; and
at least one weight track formed in the sole portion;

at least one weight assembly, selectively adjustably positioned within the at least one weight track; and
at least one brace bar traversing the interior cavity between and attached to the at least one weight track and the crown portion, wherein a mass per unit length of the brace bar is between 0.005 g/mm and 0.40 g/mm;
wherein:
the body further comprises a frame;
the frame comprises a first crown opening, a second crown opening, and a spine portion defining the crown portion and separating the first crown opening from the second crown opening;
the crown portion comprises a crown insert attached to the spine portion and covering the first crown opening and the second crown opening; and
the at least one brace bar is attached to the spine portion.

2. The golf club head according to claim 1 , wherein:
the frame further comprises a first receptacle co-formed with the at least one weight track and a second receptacle co-formed with the spine portion; and
the at least one brace bar is received within and attached to the first receptacle and the second receptacle.

3. The golf club head according to claim 2 , wherein:
the golf club head further comprises a hosel coupled to body; and
the body further comprises a hosel-brace reinforcement rib within the interior cavity of the body and extending continuously between, and coupled directly to, the hosel and the first receptacle.

4. The golf club head according to claim 2 , wherein the body further comprises a spine reinforcement rib within the interior cavity of the body and extending along and coupled directly to the spine portion of the frame and the second receptacle.

5. The golf club head according to claim 1 , wherein:
the at least one brace bar comprises a forward brace bar and a rearward brace bar; and
the forward brace bar and the rearward brace bar are spaced apart and aligned in a forward-to-rearward direction.

6. The golf club head according to claim 5 , wherein:
the forward brace bar is angled rearwardly relative to a vertical axis; and
the rearward brace bar is angled forwardly relative to the vertical axis.

7. The golf club head according to claim 6 , wherein:
the at least one weight track comprises a front weight track, extending in a heel-to-toe direction substantially parallel with the strike face of the face portion;
the at least one weight track further comprises an intermediate weight track, extending in a front-to-rear direction substantially perpendicular to the strike face of the face portion and separating a first sole opening of the body from a second sole opening of the body;
the at least one weight track further comprises a rear weight track, extending at angle relative to the intermediate weight track;
the forward brace bar is attached to an intersection between the front weight track and the intermediate weight track at a location forward of a center-of-gravity of the golf club head; and
the rearward brace bar is attached to an intersection between the intermediate weight track and the rear weight track at a location rearward of the center-of-gravity of the golf club head.

8. The golf club head according to claim 1 , wherein:
the at least one weight track comprises an intermediate weight track, extending in a front-to-rear direction substantially perpendicular to the strike face of the face portion and separating a first sole opening of the body from a second sole opening of the body;
the at least one weight track further comprises a rear weight track, extending at angle relative to the intermediate weight track; and
the brace bar is attached to at least the intermediate weight track.

9. The golf club head according to claim 1 , wherein:
the frame is made of a metal alloy; and
the crown insert is made of a fiber-reinforced polymer.

10. The golf club head according to claim 1 , wherein:
the frame further comprises a first sole opening and a second sole opening defining the sole portion of the body; and
the sole portion comprises a first sole insert attached to the frame and covering the first sole opening and a second sole insert attached to the frame and covering the second sole opening.

11. The golf club head according to claim 10 , wherein:
the first sole insert overhangs the at least one weight track; and
the second sole insert overhangs the at least one weight track.

12. The golf club head according to claim 11 , wherein:
the at least one weight track comprises an intermediate weight track, extending in a front-to-rear direction substantially perpendicular to the strike face of the face portion and separating the first sole opening from the second sole opening;
the first sole insert overhangs the intermediate weight track; and
the second sole insert overhangs the intermediate weight track.

13. The golf club head according to claim 12 , wherein:
the at least one weight track comprises a front weight track, extending in a heel-to-toe direction substantially parallel with the strike face of the face portion;
the first sole insert overhangs the front weight track; and
the second sole insert overhangs the front weight track.

14. The golf club head according to claim 1 , wherein:
the at least one weight track comprises a ledge;
the at least one weight assembly consists of an inner component and an outer component; and
the at least one weight assembly is configured to clamp the ledge between the inner component and the outer component.

15. The golf club head according to claim 1 , wherein the head further comprises a coefficient of restitution (COR) feature formed in the sole portion of the body between the face portion and the at least one weight track.

16. The golf club head according to claim 15 , wherein:
the at least one weight track comprises an intermediate weight track, extending in a front-to-rear direction substantially perpendicular to the strike face of the face portion and separating a first sole opening of the body from a second sole opening of the body; and
the COR feature comprises a channel between the face portion and the intermediate weight track and extending perpendicular to the intermediate weight track.
