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 having a sole, crown and striking face, comprising:

a frame having at least one sole opening in the sole, the frame being made at least in part of a metal or metal alloy;

a sole insert made of a polymeric material;

a weight track made of a moldable material which is joined to the sole insert to form a sole insert unit, the weight track retaining one or more slideable weights which are selectively moveable within the weight track to adjust a center of gravity of the club head;

wherein the one or more slideable weights are located on an external surface of the sole;

wherein the sole insert unit is joined to the frame to cover the at least one sole opening.

2. The golf club head of claim 1 wherein the weight track extends in a generally front to back direction on the frame.

3. The golf club head of claim 2 wherein the one or more slideable weights are adjustable to vary a Delta 1 of the club head by about 9.6 to 28.1 mm.

4. The golf club head of claim 2 wherein the sole insert unit includes a first rib extending along an internal surface of the sole insert in a first direction.

5. The golf club head of claim 4 wherein the sole insert unit includes a second rib extending along an internal surface of the sole insert in a second direction.

6. The golf club head of claim 5 wherein the first and second ribs intersect.

7. The golf club head of claim 2 wherein the sole insert is made of a composite laminate material.

8. The golf club head of claim 2 wherein the sole insert is made of a thermoplastic composite laminate material.

9. The golf club head of claim 2 wherein the sole insert is thermoformed from a continuous carbon fiber composite material.

10. The golf club head of claim 2 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 sole insert is made from a thermoplastic carbon composite material.

11. The golf club head of claim 10 wherein the sole insert has a surface area of about 20 to 50% of a surface of a sole portion of the club head.

12. The golf club head of claim 11 including a lateral weight track formed integrally as part of the frame, and one or more weights slideably retained by the lateral weight track to permit lateral toe-heel adjustment of the center of gravity.

13. The golf club head of claim 2 including an adjustable head-shaft connection assembly comprising a sleeve secured by a fastening member in a locked position, the head-shaft connection assembly 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.

14. The golf club head of claim 2 wherein the frame has at least one crown opening in the crown, and the club head further includes a crown insert made of a polymeric material which is joined to the frame to cover the crown opening.

15. The golf club head of claim 1 wherein the weight track is joined to the sole insert by injection molding, insert molding or overmolding.

16. A golf club head having a sole, crown, striking face and hosel, comprising:

a frame made at least in part of a metal or metal alloy and having at least one sole opening;

a sole insert unit made of a polymeric material and including a weight track for retaining one or more adjustable weights in different select positions along the weight track to facilitate adjustment of a center of gravity of the club head;

wherein the sole insert unit is joined to the frame to cover the at least one sole opening;

wherein the weight track extends in a generally front to back direction and the weights retained by the weight track are located on an external surface of the sole;

wherein the sole insert unit includes one or more insert ribs extending along an internal surface of the sole insert; and

a hosel rib extending from the hosel to an internal surface of the sole.

17. The golf club head of claim 16 wherein the frame and hosel rib are made of a common first material having a first density, the one or more insert ribs are made of a second material having a second density, the first density being at least twice the density of the second density.

18. The golf club head of claim 17 wherein the sole insert unit is made of a thermoplastic composite laminate material.

19. A golf club head having a sole, crown and striking face, comprising:

a frame having a hollow interior which is made at least in part of a metal or metal alloy and has a sole opening and crown opening;

a sole insert unit made of polymeric material and including a weight track for retaining one or more adjustable weights in different select positions along the weight track to facilitate adjustment of a center of gravity of the club head;

wherein the sole insert is joined to the frame to cover the sole opening, such that the weight track is generally centrally located on the sole and extends generally in a front to back direction, the one or more adjustable weights being located on an exterior surface of the sole;

a crown insert made of a polymeric material and joined to the frame to cover the crown opening; and

a plurality of ribs extending in different directions along an internal surface of the sole, wherein two or more of the ribs are made of different materials having different densities.

20. The golf club of claim 19 wherein the sole insert unit and crown insert are made of a composite laminate material.
