Golf club head
View Patent ↗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. The head may include a cast metal frame having a drop sole construction, polymeric crown insert and polymeric sole insert.
1. A wood-type golf club head comprising:
a body including a face positioned at a forward portion of the club head, a sole positioned at a bottom portion of the club head, and a crown positioned at a top portion of the club head, wherein the body defines an interior cavity;
the sole including a heel portion on one side of the body and a toe portion on an opposite side of the body, the heel portion being lower than the toe portion when the club head is in an address position relative to a ground plane;
wherein the sole includes a centrally located front-to-back slideable weight track, and the weight track separates the heel portion from the toe portion, the slideable weight track being located along a seam between sole surfaces at different levels;
the body further including a frame.
2. The club head of claim 1 wherein the heel portion overhangs at least a portion of the length of the weight track.
3. The club head of claim 1 wherein the frame includes the weight track and heel portion and defines a sole opening in the toe portion, the body further including a sole insert secured to the sole to cover the sole opening.
4. The club head of claim 3 wherein the sole insert is made of a polymer material.
5. The club head of claim 4 wherein the frame is made of a metal or metal alloy, and the sole insert is made of a polysulfone composition.
6. The club head of claim 1 wherein the sole includes a lateral weight track located proximate to the face and forward of the front-to-back weight track.
7. The club head of claim 1 wherein the heel portion is lower than the toe portion by about 2 to 12 mm.
8. The club head of claim 1 wherein the heel portion is lower than the toe portion by about 4 to 7 mm.
9. The club head of claim 1 wherein the weight track mounts at least one weight that is adjustable in the front and back direction to vary a Delta 1 of the club head by at least 5 mm.
10. A wood-type golf club head comprising:
a body including a face positioned at a forward portion of the club head, a sole positioned at a bottom portion of the club head, and a crown positioned at a top portion of the club head, wherein the body defines an interior cavity;
the body including a frame having a crown opening and a crown insert secured to the crown to cover the crown opening;
the frame having a sole opening on a toe side of the sole, the body including a sole insert secured to the sole to cover the sole opening; and
the frame including a heel-side portion on the sole, the heel-side portion being lower than the sole insert when the club head is in an address position relative to a ground plane;
the frame including a front-to-back slideable weight track located centrally on the sole, which separates the heel-side portion from the sole insert, the slideable weight track being located along a seam between sole surfaces at different levels.
11. The club head of claim 10 wherein the heel-side portion extends over at least a portion of the weight track to create an overhang.
12. The club head of claim 11 wherein the heel-side portion of the frame is lower than the sole insert by about 2 to 12 mm.
13. The club head of claim 11 wherein the weight track includes one or more adjustable weights to vary a Delta 1 of the club head by at least 5 mm.
14. The club head of claim 11 wherein the weight track includes one or more adjustable weights to vary a Delta 1 of the club head by at least 15 mm.
15. The club head of claim 11 wherein the frame includes a lateral weight track located on the sole proximate to the face and forward of the front-to-back weight track.
16. The club head of claim 15 wherein the sole insert has a sole insert surface area of about 10 to 50% of the total surface area of the sole, and the crown insert has a crown surface area of about 50 to 90% of the total surface area of the crown.
17. The club head of claim 10 wherein the crown insert and sole insert are made of a composite laminate material and 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.
18. A wood-type golf club head comprising:
a body including a face positioned at a forward portion of the club head, a sole positioned at a bottom portion of the club head, and a crown positioned at a top portion of the club head, wherein the body defines an interior cavity;
the body including a frame having a sole opening and a crown opening;
the body including a sole insert secured to the frame to cover the sole opening and a crown insert secured to the frame to cover the crown opening;
the crown insert having a first surface area of at least 50% of the total surface area of the crown, and the sole insert having a second surface area less than about 50% of the total surface area of the sole; and
the sole having a bi-level construction such that a heel portion of the sole is lower relative to a toe portion of the sole when the head is in an address position relative to a ground plane;
wherein the body includes a front-to-back slideable weight track on the sole located between the heel portion and toe portion, the slideable weight track being located along a seam between sole surfaces at different levels.
19. The club head of claim 18 wherein the weight track defines a channel and the heel portion overhangs at least a portion of the channel.
20. The club head of claim 19 wherein the toe portion is located on a toe side of the weight track and the heel portion is located on a heel side of the weight track.
21. The club head of claim 20 wherein the toe portion includes the sole insert, and the sole insert includes a sulfone matrix material, and the frame is made of a metal material or metal alloy.
22. The club head of claim 18 wherein the bi-level difference is about 4 to 7 mm.
23. The club head of claim 18 wherein the frame including the front-to-back weight track located centrally on the sole, wherein the weight track mounts at least one weight that is adjustable in the front and back direction to vary a Delta 1 of the club head by at least 5 mm.
