Abstract

Described herein is a golf club head that includes a body with a sole portion, a crown portion, a skirt portion, a forward region, and a rearward region. The golf club head also includes a face portion including a striking face with a maximum height from the ground plane of at least about 50 mm. A volume of the golf club head is at least about 370 cm 3 . The golf club head has a total club head mass between 190 grams and 210 grams, and the mass of the club head located above half of the peak crown height is less than or equal to 77 grams, and the percentage of the mass above half of the peak crown height is less than or equal to 39% of the total mass of the golf club head.

First claim

What is claimed is:

1. A golf club head, comprising:
a frame having at least one 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 comprising a striking face with an area of at least 3500 mm 2 and a maximum height from a ground plane of at least about 50 mm, an aft end positioned at a rear portion of the frame, and a hosel extending from a heel side of the frame, the frame being made at least in part of a metal or metal alloy;
a crown insert joined to the frame to cover the crown opening, the crown insert comprising a non-metal material;
a sole insert joined to the frame to cover the sole opening, the sole insert comprising a non-metal material; and
a first weight secured to the lower portion of the frame proximate the rear portion of the frame;
wherein:
the lower portion of the frame includes a heel-side shaft connection port including a fastener opening for connecting a flight control technology (FCT) component,
the golf club head has a crown height as measured relative to a ground plane when the club head is in a normal address position,
there is a first crown height at a face-to-crown transition region where the face connects to a crown of the club head near a front end of the frame, a second crown height at a crown-to-skirt transition region where the crown connects to a skirt of the golf club head near the aft end of the frame, and a maximum crown height located on the crown insert rearward of the first crown height and forward of the second crown height,
the maximum crown height is greater than both the first and second crown heights,
the golf club head has a total club head mass between 190 grams and 210 grams, and a mass of the club head located above half of a peak crown height is less than or equal to 77 grams, and a percentage of the mass of the club head located above half of the peak crown height is less than or equal to 39% of the total club head mass of the golf club head,
the first weight is secured to the frame, at a location rearward of the sole opening, and
the golf club head has a moment of inertia about a CG z-axis (Izz) and a moment of inertia about a CG x-axis (Ixx), and a ratio of Ixx to Izz is at least 0.62 and Izz is greater than 400 kg−mm{circumflex over ( )}2.

2. The golf club head of claim 1 , wherein the frame comprises a combination of two or more materials having different densities.

3. 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 the sole insert is made from a carbon composite material.

4. The golf club head of claim 2 , wherein the face comprises a face opening and a face plate received in the face opening.

5. The golf club head of claim 4 , wherein the face plate comprises a composite material.

6. The golf club head of claim 1 , wherein the sole insert has a surface area of at least 20% of a surface area of a sole portion of the club head.

7. The golf club head of claim 1 , wherein the face comprises a face opening and a face plate received in the face opening.

8. The golf club head of claim 7 , wherein the face plate comprises a composite material.

9. The golf club head of claim 8 , further comprising a second weight secured to the lower portion of the frame proximate the forward portion of the frame and toe-ward of the heel-side shaft connection port, wherein the second weight comprises a screw configured to secure the second weight to the lower portion of the frame.

10. The golf club head of claim 9 , wherein the second weight is secured to the frame forward of the sole opening.

11. The golf club head of claim 9 , wherein the second weight is secured to the frame forward of the sole opening and within a recessed portion of the frame, and the recessed portion of the frame is proximate the heel-side shaft connection port.

12. The golf club head of claim 11 , wherein the recessed portion of the frame comprises a weight track, and wherein the second weight is configured to slide within the weight track.

13. The golf club head of claim 9 , wherein a center of gravity (CG) projection onto the striking face is at most 3 mm above a geometric center of the striking face.

14. The golf club head of claim 13 , wherein the ratio of Ixx to Izz is at least 0.65.

15. The golf club head of claim 1 , wherein the ratio of Ixx to Izz is at least 0.65, and the face comprises a face opening and a face plate received in the face opening.

16. The golf club head of claim 15 , wherein the face plate comprises a composite material.

17. The golf club head of claim 16 , wherein a center of gravity (CG) projection onto the striking face is at most 3 mm above a geometric center of the striking face.

18. The golf club head of claim 17 , wherein the frame comprises a combination of two or more materials having different densities and the sole insert has a surface area of at least 20% of a surface area of a sole portion of the club head.

19. A golf club head, comprising:
a frame having at least one 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 comprising a striking face with an area of at least 3500 mm 2 and a maximum height from a ground plane of at least about 50 mm, an aft end positioned at a rear portion of the frame, and a hosel extending from a heel side of the frame, the frame being made at least in part of a metal or metal alloy;
a crown insert joined to the frame to cover the crown opening, the crown insert comprising a non-metal material;
a sole insert joined to the frame to cover the sole opening, the sole insert comprising a non-metal material; and
a first weight secured to the lower portion of the frame proximate the rear portion of the frame;
wherein:
the lower portion of the frame includes a heel-side shaft connection port including a
fastener opening for connecting a flight control technology (FCT) component,
