Abstract

A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ΔCGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ΔCGz) that is less than 2 mm.

First claim

The invention claimed is:

1. A golf club head, comprising:
a club head body having a crown portion, a sole portion, a toe portion, a heel portion, a rear portion, and a front portion together defining an interior cavity, wherein:
the club head body has a striking surface located at the front portion of the club head body, and a head origin defined as a position on the striking surface at approximately a geometric center of the striking surface, the head origin including a head origin x-axis, a head origin y-axis, and a head origin z-axis;
the head origin x-axis is tangential to the striking surface and generally parallel to a ground plane when the head is in an address position and a positive x-axis extends towards a heel portion;
the head origin y-axis extends perpendicular to the head origin x-axis and generally parallel to the ground plane when the head is in the address position and a positive y-axis extends from the striking surface and through the rear portion of the club head body;
the head origin z-axis extends perpendicular to the ground plane, and perpendicular to both the head origin x-axis and y-axis when the head is in the address position and a positive z-axis extends from the head origin and generally upward;
the golf club head has a center of gravity, and the center of gravity has a head origin x-axis (CGx) coordinate greater than about-3 mm and less than about 8 mm, and a head origin y-axis (CGy) coordinate greater than about 22 mm and less than 43 mm;
the golf club head center of gravity has a head origin z-axis (CGz) coordinate less than about 3 mm;
the golf club head has a moment of inertia about a center of gravity x-axis (CG x-axis), the CG x-axis is parallel to the head origin x-axis and passes through the center of gravity of the golf club head;
the golf club head has a moment of inertia about a center of gravity z-axis (CG z-axis), the CG z-axis is parallel to the head origin z-axis and passes through the center of gravity of the golf club head;
the golf club head has a moment of inertia about a center of gravity y-axis (CG y-axis), the CG y-axis is parallel to the head origin y-axis and passes through the center of gravity of the golf club head;
the golf club head moment of inertia about the CG x-axis is between about 200 kg mm 2 and 500 kg mm 2 , the golf club head moment of inertia about the CG y-axis is between about 200 kg mm 2 and 400 kg mm 2 , and the moment of inertia about the CG z-axis is between about 350 kg mm 2 and about 600 kg mm 2 ;
an areal weight of the crown portion is less than about 0.36 g/cm 2 over at least about 50% of an entire crown portion surface area, and wherein the crown portion is at least partially formed of a composite material having a density between 1 g/cc and 2 g/cc;
the club head body has a volume of at least 400 cubic centimeters;
the front portion comprises a face opening, and the striking surface comprises a face plate received in the face opening to thereby close the face opening;
the golf club head further comprises an adjustable head-shaft connection assembly comprising a sleeve secured in place by a fastening member in a locked position, wherein the adjustable head-shaft connection assembly is configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, or lie angle;
the golf club head further comprises a plurality of ribs located on an internal surface of the sole portion;
the golf club head further comprises one or more weight ports and at least one weight removably attached to the one or more weight ports;
the one or more weight ports comprise a first weight port and a second weight port;
a distance between the first and second weight ports is between 50 mm and 100 mm;
the at least one weight is configured to move between at least a first position and at least a second position;
the first position is rearward of the center of gravity and the second position is forward of the center of gravity;
moving the at least one weight provides a maximum y-axis adjustment range of the position of the center of gravity that is greater than 2 mm;
the composite material of the crown portion forms a composite crown panel that is bonded to one or more attachment surfaces located on the golf club head;
the one or more attachment surfaces has a width that is at least four times a thickness of the composite crown panel; and
the golf club head has a Δz (Z-up) value between 20 mm and 30 mm.

2. The golf club head of claim 1 , wherein at least a portion of the sole portion is formed from a composite material having a density less than 2 g/cc.

3. The golf club head of claim 1 , wherein the face plate is welded in place in the face opening.

4. The golf club head of claim 1 , wherein the face plate is bonded in place in the face opening and is made of a composite material.

5. The golf club head of claim 4 , wherein the face plate comprises forty or more plies.

6. The golf club head of claim 5 , wherein the composite material of the crown portion comprises four or more plies.

7. The golf club head of claim 1 , wherein the golf club head has a head height as measured relative to a ground plane when the golf club head is in an address position on the ground plane, wherein a first head height is defined at a face-to-crown transition where the face connects to the crown near a front end of the golf club head, a second head height is defined at a crown-to-skirt transition where the crown connects to a skirt of the golf club head near a rear end of the golf club head, and a maximum head height, greater than both the first and second head heights, is located on the crown insert rearward of the first head height and forward of the second head height.

8. The golf club head of claim 1 , wherein at least one rib of the plurality of ribs is attached to at least one of the one or more weight ports.
