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

What is 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 body further comprises a slot configured to receive the first end of the hosel, 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; 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.

2. The golf club head of claim 1 , wherein the plurality of different angles between the body and the shaft comprises a plurality of different loft angles between the body and the shaft.

3. The golf club head of claim 1 , wherein the plurality of different angles between the body and the shaft comprises a plurality of different lie angles between the body and the shaft.

4. The golf club head of claim 1 , wherein the insert is configured to be coupled to the first end of the hosel, and wherein the second end of the hosel and the shaft are rotationally connected to provide an adjustable angle between the hosel and the shaft.

5. The golf club head of claim 1 , wherein the insert comprises a plurality of projections and the recess comprises a plurality of adjustment recesses, wherein engagement of the projections with a selected plurality of adjustment recesses of the plurality of adjustment recesses provides an angle between the body and the shaft corresponding to the selected plurality of adjustment recesses.

6. The golf club head of claim 1 , wherein the first end of the hosel comprises a threaded bore configured to receive a bolt, wherein the insert comprises a hole, and wherein at each of the plurality of rotational positions of the insert, the hole is alignable at a different angle with the threaded bore to provide engagement of the bolt through the hole and with the threaded bore.

7. The golf club head of claim 1 , wherein the insert comprises a first rotational position corresponding to a negative angle between the body and the shaft, a second rotational position corresponding to a neutral angle between the body and the shaft, and a third rotational position corresponding to a positive angle between the body and the shaft.

8. The golf club head of claim 1 , wherein the first end of the hosel comprises a threaded bore configured to receive a bolt inserted from the sole portion through the insert to fix the body relative to the shaft at the one rotational position.
