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.

Claims

1-6. -6. (canceled)

7. A golf club head comprising:

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, wherein the distance between a first vertical plane intersecting a center of the face and the channel is less than about 50 mm over a full length of the channel;

at least one weight port located rearward of the channel;

at least one weight movably positioned within the channel, wherein a position of the at least one weight within the channel is able to be adjusted;

an installation cavity for installing the at least one weight within the channel; and

at least one ledge extending within the channel generally from a heel end of the channel to a toe end of the channel, and wherein the at least one weight is configured to clamp onto the at least one ledge.

14. The golf club head of claim 7, wherein the at least one weight is a weight assembly including a washer, a mass member, and a fastening member, wherein the weight assembly has a mass between 5 g and 25 g;

wherein the fastening member is in tension when the weight assembly is clamped to the at least one ledge.

15. The golf club head of claim 7, wherein the Max Δ

CGz is approximately 1.0 mm throughout the adjustability range.

16. The golf club head of claim 7, wherein the at least one weight port is located on an aft winglet, and the at least one weight port defining a central axis that extends through the sole and the crown, and the at least one weight port is configured to retain a first weight and the first weight is interchangeably installable in the at least one weight port and the channel.

24. A golf club head comprising:

a body having a face, a crown and a sole together defining an interior cavity,

the body having a channel located on the sole wherein the channel includes a front channel wall and a rear channel wall, and wherein a width of the channel is be between about 8 mm and about 20 mm, and a depth of the channel is be between about 6 mm and about 20 mm;

at least one weight assembly movably positioned within the channel, wherein a position of the at least one weight within the channel is able to be adjusted, wherein the at least one weight assembly weighs between about 5 g and about 25 g and includes a washer, a mass member, and a fastening bolt;

an installation cavity for installing the weight assembly in the channel; and

at least one ledge within the channel, wherein the at least one weight assembly is configured to clamp onto the at least one ledge, and wherein the fastening bolt is in tension when the weight assembly is clamped to the at least one ledge;

at least one weight port located rearward of the channel on an aft winglet, wherein the at least one weight port defining a central axis that extends through the sole and the crown;

at least one rib provided on an internal surface of the interior cavity, wherein the at least one rib connects the channel interior surface to at least one other internal surface of the body.

25. A golf club head comprising:

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, wherein the channel includes a front channel wall and a rear channel wall, and wherein a width of the channel is between about 8 mm and about 20 mm;

a heel opening located on the heel end of the body, the heel opening configured to receive a fastening member; and

a head-shaft connection system including a sleeve that is secured by the fastening member in a locked position, the head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in an adjustability range of different combinations of loft angle, face angle, or lie angle;

at least one weight port located rearward of the channel; and

wherein the golf club head has a volume greater than about 400 cc.
