## Abstract

Disclosed herein are some embodiments of a golf club head with a tapered sole weight. One embodiment comprises a golf club head comprising a sole weight; and a body comprising a sole comprising an exterior sole surface, wherein a sole weight port is formed in the sole. The sole weight port can have a port top comprising an interior port top surface and an exterior port top surface, wherein the interior port top surface has a taper of plus or minus approximately 1-89 degrees with respect to the exterior port top surface. The sole weight port can comprise a weight-receiving cavity that engages the sole weight. Other embodiments for related club heads and methods are also disclosed.

## Claims

### Claim 1

A golf club head comprising:
a sole weight; and
a body comprising:
a sole comprising an exterior sole surface; and
a sole weight port comprising:
a port top comprising an interior port top surface and an exterior port top surface, the interior port top surface having a taper of plus or minus approximately 1-89 degrees with respect to the exterior port top surface;
a weight-receiving cavity that engages the sole weight; wherein,
the sole and the sole weight port are co-molded, such that the sole surrounds the sole weight port;
wherein the sole weight has a lower density than the sole weight port; and
wherein the body is made of one or more materials having a high shear modulus.

### Claim 2 (depends on 1)

The golf club head of claim 1, wherein the body comprises a front end and a rear end, and the sole weight port is located closer to the rear end than the front end.

### Claim 3 (depends on 1)

The golf club head of claim 1, wherein the port top includes a threaded screw-receiving portion, and the sole weight includes a screw-receiving hole.

### Claim 4 (depends on 1)

The golf club head of claim 1, wherein the sole weight comprises a tapered geometry that forms a self-aligned fitting system, which allows the sole weight to be placed in the sole weight port in only one orientation.

### Claim 5 (depends on 1)

The golf club head of claim 1, wherein the sole weight comprises a material selected from the group consisting of: a thermoplastic elastomer, aluminum, steel, titanium, tungsten, a suitable metal alloy, and a thermoplastic elastomer with metal additives.

### Claim 6 (depends on 1)

The golf club head of claim 1, the sole weight port further comprises:
one or more port side walls; and
a weight-receiving cavity opening to the exterior sole surface and bounded by the exterior port top surface and the one or more port side walls.

### Claim 7 (depends on 6)

The golf club head of claim 6, wherein a rear side of the one or more port side walls and the interior port top surface can extend from the sole weight port to a side of the body.

### Claim 8 (depends on 1)

The golf club head of claim 1, wherein either one or both of the interior port top surface and the exterior port top surface taper in a front-to-rear direction.

### Claim 9 (depends on 1)

The golf club head of claim 1, wherein either one or both of the interior port top surface and the exterior port top surface taper in a heel-to-toe direction.

### Claim 10 (depends on 1)

The golf club head of claim 1, wherein either one or both of the interior port top surface and the exterior port top surface taper in both a front-to-rear direction and a heel-to-toe direction.

### Claim 11

A golf club head comprising:
a sole weight; and
a body comprising:
a sole comprising an exterior sole surface; and
a sole weight port comprising:
a port top comprising an interior port top surface and an exterior port top surface, the interior port top surface having a taper of plus or minus approximately 1-89 degrees with respect to the exterior port top surface;
a weight-receiving cavity that engages the sole weight; wherein,
the sole and the sole weight port are co-molded, such that the sole surrounds the sole weight port;
wherein the sole weight has a higher density than the sole weight port; and
wherein the body is made of one or more materials having a high shear modulus.

### Claim 12 (depends on 11)

The golf club head of claim 11, wherein the body comprises a front end and a rear end, and the sole weight port is located closer to the rear end than the front end.

### Claim 13 (depends on 11)

The golf club head of claim 11, wherein the port top includes a threaded screw-receiving portion, and the sole weight includes a screw-receiving hole.

### Claim 14 (depends on 11)

The golf club head of claim 11, wherein the sole weight comprises a tapered geometry that forms a self-aligned fitting system, which allows the sole weight to be placed in the sole weight port in only one orientation.

### Claim 15 (depends on 11)

The golf club head of claim 11, wherein the sole weight comprises a material selected from the group consisting of: a thermoplastic elastomer, aluminum, steel, titanium, tungsten, a suitable metal alloy, and a thermoplastic elastomer with metal additives.

### Claim 16 (depends on 11)

The golf club head of claim 11, wherein either one or both of the interior port top surface and the exterior port top surface taper in a front-to-rear direction.

### Claim 17 (depends on 11)

The golf club head of claim 11, wherein either one or both of the interior port top surface and the exterior port top surface taper in a heel-to-toe direction.

### Claim 18 (depends on 11)

The golf club head of claim 11, wherein:
the body has a volume of no more than 350 cubic centimeters; and
the body comprises a face having a loft angle of approximately 17-31 degrees relative to a vertical plane perpendicular to a horizontal plane when the golf club head is at an address position.

### Claim 19 (depends on 11)

The golf club head of claim 11, wherein:
the sole weight port further comprises:
one or more port side walls; and
a weight-receiving cavity opening to the exterior sole surface and bounded by the exterior port top surface and the one or more port side walls.

### Claim 20 (depends on 19)

The golf club head of claim 19, wherein a rear side of the one or more port side walls and the interior port top surface can extend from the sole weight port to a side of the body.
