Abstract

Disclosed golf club heads include a body defining an interior cavity, a face, a sole, a crown, a skirt, and a hosel. Some embodiments include one or more of a split mass pad and/or one or more weight ports positioned in a sole portion of the body. Additionally or alternatively, one or more mass pads or weight ports may be positioned adjacent to the periphery of the sole portion. Some embodiments further include an adjustable head-shaft connection assembly configured to adjustably couple the hosel to a golf club shaft.

First claim

We claim:

1 . A golf club head, comprising:
a golf club head body, defining an interior cavity, a top portion, and a rearward portion of the golf club head, and comprising:
a sole, defining a bottom portion of the golf club head;
a skirt portion, defining a periphery of the golf club head between the sole and a crown of the golf club head;
a face, defining a forward portion of the golf club head and extending between a heel portion of the golf club head, defined by the golf club head body, and a toe portion of the golf club head, defined by the golf club head body, wherein the rearward portion the golf club head is opposite the face;
a hosel;
a recessed port, located on a heel-side of the sole;
a hosel bore, extending through the hosel and open to the recessed port;
a crown opening and a recessed ledge along at least a forward portion of the crown opening;
wherein:
the recessed ledge receives a crown insert;
the crown insert covers the crown opening; and
the crown insert:
 has a density between 1 gram per cubic centimeter (g/cc) and 2 g/cc,
 has a surface area of at least 4,000 square millimeters, and
 defines at least 60% of a total surface area of the crown of the golf club head; and

a mass body, attached to the golf club head body at least at a forward portion of the sole, wherein the mass body has a mass between 20 grams and 80 grams, wherein the mass body extends from a first location on the sole proximate the recessed port to a second location on the sole on the toe portion, and wherein a forward portion of the mass body is forward of a rearward portion of the recessed port.

2 . The golf club head of claim 1 , wherein the first location is at least as far heelward as a toewardmost portion of the recessed port.

3 . The golf club head of claim 1 , wherein:
the golf club head body further comprises a channel comprising a channel opening extending into the interior cavity of the golf club head; the channel extends in a toe-heel direction across the sole, with a heelward end near the recessed port and an opposite toeward end; and the channel is positioned forward of the mass body.

4 . The golf club head of claim 3 , wherein the second location is at least as far toeward as a toewardmost portion of the channel opening.

5 . The golf club head of claim 1 , further comprising at least one removable weight, having a mass between approximately 0.5 gram and approximately 30 grams, and configured to be attached to the golf club head.

6 . The golf club head of claim 1 , wherein the golf club head has a balance point located on the face and the golf club head has a coefficient of restitution (COR) of no less than 0.80 as measured at the balance point on the face, and at least a portion of the golf club head body positioned forward of the mass body, toeward of the mass body, and heelward of the mass body is made of a titanium alloy.

7 . The golf club head of claim 1 , wherein the golf club head has an above ground center-of-gravity location, Zup, that is between 13.5 mm to 18 mm, and the golf club head has a height less than about 46 mm and a volume of between about 125 and 240 cm 3 .

8 . The golf club head of claim 7 , wherein the golf club head has a moment of inertia about an x axis (Ixx) between 70 kg-mm 2 and 220 kg-mm 2 and a moment of inertia about a z axis (Izz) between 170 kg-mm 2 and 375 kg-mm 2 .

9 . The golf club head of claim 8 , wherein Ixx is no less than 100 kg-mm 2 .

10 . The golf club head of claim 9 , wherein the golf club head has a center of gravity located horizontally rearward of a center of the face of less than about 40 mm and Izz is no less than 300 kg-mm 2 .

11 . A golf club head, comprising:
a golf club head body, defining an interior cavity, a top portion, and a rearward portion of the golf club head, and comprising:
a sole, defining a bottom portion of the golf club head;
a skirt portion, defining a periphery of the golf club head between the sole and a crown of the golf club head;
a face, defining a forward portion of the golf club head and extending between a heel portion of the golf club head, defined by the golf club head body, and a toe portion of the golf club head, defined by the golf club head body, wherein the rearward portion the golf club head is opposite the face;
a hosel;
a channel comprising a channel opening extending into the interior cavity of the golf club head, and wherein the channel extends in a toe-heel direction across the sole, with a heelward end near the hosel and an opposite toeward end;
a mass body, attached to the golf club head body at least at a forward portion of the sole, wherein the mass body has a mass between 20 grams and 80 grams; and a crown opening and a recessed ledge along at least a forward portion of the crown opening;
wherein:
the recessed ledge receives a crown insert,
the crown insert covers the crown opening, and
the crown insert:
has a density between 1 gram per cubic centimeter (g/cc) and 2 g/cc,
has a surface area of at least 4,000 square millimeters, and
defines at least 60% of a total surface area of the crown of the golf club head;

the mass body extends from a first location, on a heel-side of the sole, to a second location, on a toe-side of the sole, and the second location is at least as far toeward as a toewardmost portion of the channel opening; and
the channel is positioned forward of the mass body.

12 . The golf club head of claim 11 , wherein:
at the forward portion of the golf club head and heelward of the mass body, the golf club head body is made of a titanium alloy; at the forward portion of the golf club head and toeward of the mass body, the golf club head body is made of a titanium alloy that is the same as or different than the titanium alloy heelward of the mass body; and the golf club head has a center of gravity that is located less than about 40 millimeters horizontally rearward of a geometric center of the face when the golf club head is in a normal address position on a horizontal plane.

13 . A golf club head, comprising:
a golf club head body, defining an interior cavity, a top portion, and a rearward portion of the golf club head, and comprising:
a sole, defining a bottom portion of the golf club head;
a skirt portion, defining a periphery of the golf club head between the sole and a crown of the golf club head;
a face, defining a forward portion of the golf club head and extending between a heel portion of the golf club head, defined by the golf club head body, and a toe portion of the golf club head, defined by the golf club head body, wherein the rearward portion the golf club head is opposite the face;
a hosel;
a crown opening, at the top portion of the golf club head, and a recessed ledge along at least a forward portion of the crown opening;
a recessed port, located on a heel-side of the sole;
a hosel bore, extending through the hosel and open to the recessed port;
a mass body having a mass between 20 grams and 80 grams located at least in a forward portion of the sole and extending from a first location, on a heel-side of the sole, to a second location, on a toe-side of the sole;
a channel comprising a channel opening extending into the interior cavity of the golf club head, and wherein the channel extends in a toe-heel direction across the sole, with a heelward end near the recessed port and an opposite toeward end, and the channel is positioned forward of the mass body; and
a crown insert received by the recessed ledge, and attached to the golf club head body such that the crown insert covers the crown opening; and
wherein:
the first location is
