Abstract

Embodiments of golf clubs with adjustable lie and loft and methods of manufacturing golf clubs with adjustable lie and loft are generally described herein. Other embodiments may be described and claimed.

First claim

The invention claimed is:

1. A golf club head comprising:
a body having a top rail portion, a sole portion, and a recess portion extending between the top rail portion and the sole portion;
a hosel comprising a first end configured to rotationally connect to the body and a second end configured to receive a shaft,
wherein the hosel comprises a front side, a toe side, a heel side, and a rear side,
wherein the hosel first end comprises a curvature from the hosel front side to the hosel rear side,
wherein the body further comprises a slot configured to receive the first end of the hosel,
wherein the slot comprises a top side, a front side, a toe side, a heel side, and a rear side,
wherein the slot top side comprises a curvature from the slot front side to the slot rear side,
wherein the hosel is connected in the slot with at least one pin extending through the body and engaged in a bore in the hosel, and
wherein the bore in the hosel defines an axis of rotation of the hosel relative to the body,
wherein the bore in the hosel extends from the heel side of the hosel through to the toe side of the hosel,
and
an insert configured to be inserted in the recess portion and coupled to the first end of the hosel,
the insert configured to be positioned in the recess portion at one rotational position of a plurality of different rotational positions corresponding to a plurality of different angles between the body and the shaft,
wherein the first end of the hosel comprises a bolt configured to be inserted through the insert and engaged with a threaded bore from the sole portion to fix the body relative to the shaft at the one rotational position.

2. The golf club head of claim 1 , wherein the recess portion comprises a first recess section extending from the sole portion toward the top rail portion, and a second recess section extending from the first recess section toward the top rail portion, the second recess section having at least one smaller dimension than a corresponding dimension of the insert to prevent insertion of the insert into the second recess section.

3. The golf club head of claim 1 , wherein the recess portion comprises a first recess section extending from the sole portion toward the top rail portion, and a second recess section extending from the first recess section toward the top rail portion and configured to receive the bolt, the second recess section having at least one smaller dimension than a corresponding dimension of the insert to prevent insertion of the insert into the second recess section.

4. The golf club head of claim 1 , wherein the insert further comprises a plurality of holes, wherein each of the plurality of holes are alignable with the bore in the hosel at one rotational position of the plurality of different rotational positions, and each of the plurality of holes correspond to a different angle of the plurality of different angles between the body and the shaft.

5. The golf club head of claim 4 , wherein the plurality of different angles between the body and the shaft comprise a plurality of different loft angles.

6. The golf club head of claim 4 , wherein the plurality of holes of the insert include a first hole corresponding to a first loft angle at a first rotational position of the insert, a second hole corresponding to a second loft angle at a second rotational position of the insert, and a third hole corresponding to a third loft angle at a third rotational position of the insert.

7. The golf club head of claim 6 , wherein the first loft angle is a neutral loft angle, the second loft angle is greater than the first loft angle, and the third loft angle is less than the first loft angle.

8. A method of manufacturing a golf club head comprising:
forming a body having a top rail portion, a sole portion, and a recess portion extending between the top rail portion and the sole portion;
forming a hosel comprising a first end configured to rotationally connect to the body and a second end configured to receive a shaft,
wherein the hosel comprises a front side, a toe side, a heel side, and a rear side,
wherein the hosel first end comprises a curvature from the hosel front side to the hosel rear side,
wherein the body further comprises a slot configured to receive the first end of the hosel,
wherein the slot comprises a top side, a front side, a toe side, a heel side, and a rear side,
wherein the slot top side comprises a curvature from the slot front side to the slot rear side,
wherein the hosel is connected in the slot with at least one pin extending through the body and engaged in a bore in the hosel, and
wherein the bore in the hosel defines an axis of rotation of the hosel relative to the body,
wherein the bore in the hosel extends from the heel side of the hosel through to the toe side of the hosel,
and
forming an insert configured to be inserted in the recess portion and coupled to the first end of the hosel, the insert configured to be positioned in the recess portion at one rotational position of a plurality of different rotational positions corresponding to a plurality of different angles between the body and the shaft,
wherein the insert further comprises a plurality of holes, wherein each of the plurality of holes are alignable with the bore in the hosel at one rotational position of the plurality of different rotational positions, and each of the plurality of holes correspond to a different angle of the plurality of different angles between the body and the shaft.

9. The method of manufacturing of claim 8 , wherein the plurality of different angles between the body and the shaft comprise a plurality of different loft angles.

10. The method of manufacturing of claim 8 , wherein the plurality of holes of the insert include a first hole corresponding to a first loft angle at a first rotational position of the insert, a second hole corresponding to a second loft angle at a second rotational position of the insert, and a third hole corresponding to a third loft angle at a third rotational position of the insert.
