Claims10
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 hosel section and a second hosel section,
- wherein the first hosel section connects to the body,
- wherein the second hosel section connects to a shaft, and
- wherein the first hosel section connects to the second hosel section,
- wherein the first hosel section comprises a first hosel section first end configured to rotationally connect to the body and a first hosel section second end configured to connect to the second hosel section,
- wherein the first hosel section comprises a front side, a toe side, a heel side, and a rear side,
- wherein the first hosel section first end comprises a curvature from the first hosel section front side to the first hosel section rear side,
- wherein the first hosel section second end comprises a first bore,
- wherein the second hosel section comprises a second bore,
- wherein a first bolt connects the first hosel section second end to the second hosel section through the first bore in the first hosel section second end and the second bore in the second hosel section such that the second hosel section is able to rotate relative to the first hosel section when the first bolt is not tightened,
- wherein the second hosel section is fixed and non-rotating relative to the first hosel section when the first bolt is tightened,
- wherein the body further comprises a slot configured to receive the first hosel section first end,
- 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 first hosel section first end is connected in the slot with at least one pin extending through the body and engaged in a third bore in the first hosel section first end, and
- wherein the third bore in the first hosel section first end defines an axis of rotation of the hosel relative to the body,
- wherein the third bore in the first hosel section first end extends from the heel side of the first hosel section first end through to the toe side of the first hosel section first end,
- and
- an insert configured to be inserted in the recess portion and coupled to the first hosel section first end,
- 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 hosel section first end comprises a second 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.
