Golf club heads
Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.
1. A wood-type golf club head comprising:
a front side, a rear side, a top side, a bottom side, a toe side, and a heel side, the club head comprising a face positioned at the front side of the club head, a hosel positioned at the heel side of the club head, a sole positioned at the bottom side of the club head, and a crown positioned at the top side of the club head, the club head having an interior cavity and a volume of from about 350 cm 3 to about 600 cm 3 ;
a club head body defining an upper crown opening, a toe-side sole opening, and a heel-side sole opening;
a crown insert that is secured to the body over the crown opening;
a sole insert that is positioned inside the body and secured to the body over the toe-side sole opening and over the heel-side sole opening;
a front channel in the sole adjacent to the face and forward of the toe-side sole opening and the heel-side sole opening; and
a rear weight track positioned on the sole below the sole insert and between the toe-side sole opening and the heel-side sole opening in the body.
2. The club head of claim 1 , further comprising at least one slidably adjustable weight assembly mounted in the rear weight track and configured to adjust a CGy of the golf club head.
3. The club head of claim 1 , wherein the front channel comprises a front weight track extending in a heel-toe direction, and the club head further comprises at least one slidably adjustable weight assembly mounted in the front weight track and configured to adjust a CGx of the golf club head.
4. The club head of claim 1 , further comprising an adjustable head-shaft connection assembly coupled to the hosel and configured to a user to adjust an orientation of the club head relative to a golf club shaft.
5. The club head of claim 1 , further comprising a plurality of external ribs on the sole positioned toeward of the front channel, the plurality of external ribs reinforcing a lower toe portion of the front side of the club head.
6. The club head of claim 1 , wherein the sole comprises a rear ground contact surface positioned rearward of the front channel and heelward of the rear weight track.
7. The club head of claim 1 , further comprising an internal rib extending from the hosel toeward across an interior side of the front channel.
8. The club head of claim 1 , wherein the club head body comprises a front crown portion forward of the upper crown opening, and wherein a rear end of the front crown portion includes a recessed ledge that receives a front end of the crown insert.
9. The club head of claim 8 , wherein the front crown portion has a toe-side portion, a heel-side portion, and a center portion between the toe-side and heel-side portions, wherein the center portion has a depth L 1 in a front-rear direction and the toe-side portion has a depth L 2 in the front-rear direction; and wherein L 1 <L 2 such that the recessed ledge is closer to the front side at the center portion than at the toe-side portion.
10. The club head of claim 1 , wherein the golf club head defines a forgiveness ratio that is at least 0.915, wherein the forgiveness ratio is defined as (hosel axis to back dimension)*(face area)/(volume).
11. The club head of claim 10 , wherein a ratio of the club head's moment of inertia about its z-axis to the volume of the club head is greater than 0.99 kg/m.
12. The club head of claim 10 , wherein the golf club head has a forgiveness ratio of at least 0.970.
13. The club head of claim 1 , wherein the body includes ledges that at least partially surround the toe-side sole opening and the heel-side sole opening, and the ledges are configured to seat the sole insert such that the sole insert is flush with surrounding portions of the body.
