Abstract

A golf club head includes a metal frame having a sole opening, a composite laminate crown joined to the frame, a composite laminate sole insert joined to the frame and overlying the sole opening, and a thermoplastic composite component overmolded on the sole insert. The composite component may include a weight track, ribs, supports or other features. A method of making the golf club includes the steps of forming a frame having a sole opening, forming a composite laminate sole insert, forming a composite laminate crown insert, injection molding a thermoplastic composite head component over the sole insert to create a sole insert unit, and joining the sole insert unit and crown insert to the frame.

Claims

1. A golf club head comprising:

a frame having a sole opening positioned at a lower portion of the frame, a crown opening positioned at an upper portion of the frame, a face positioned at a forward portion of the frame, an aft end positioned at a rear portion of the frame, and a lateral weight track configured to receive one or more laterally slideably adjustable weights, the lateral weight track being located forward of the sole opening, wherein movement of the one or more laterally slideably adjustable weights adjusts a center of gravity of the club head;

a sole insert secured to the frame to cover the sole opening;

a crown insert secured to the frame to cover the crown opening;

the frame further including one or more weight ports located at the rear portion of the frame, rearward of the lateral weight track; and

an adjustable head-shaft connection assembly comprising a sleeve secured by a 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 different combinations of loft angle, face angle, or lie angle.

2. The golf club head of claim 1 wherein the frame is made of a metal material and the lateral weight track and one or more weight ports are an integral part of the frame.

3. The golf club head of claim 1 wherein the sole and crown inserts are made of a thermoplastic composite material.

4. The golf club head of claim 1 further comprising two fixed weight ports located centrally at the aft end of the club head.

5. The golf club head of claim 1 wherein the frame is made of a material selected from the group consisting of titanium, one or more titanium alloys, aluminum, one or more aluminum alloys, steel, one or more steel alloys, and any combination thereof and the sole and crown inserts are each made from a thermoplastic carbon composite material.

6. The golf club head of claim 1 further including at least one weight removably attached to the one or more weight ports.

7. The golf club head of claim 1 wherein the frame, lateral weight track and one or more weight ports are made at least in part from a metal material and form an integrated cast structure.

8. The golf club head of claim 1 wherein the sole insert has a surface area of about 25 to 50% of a surface area of a sole portion of the club head.

9. The golf club head of claim 1 wherein the lateral weight track of the club head is positioned such that the club head has a center of gravity projection of about 1 to 2.2 mm.

10. The golf club head of claim 1 wherein the club head has a Delta 1 of about 18.9 to 25.5 mm.
