Claims13
A golf club head comprising:
- a club head body comprising:
- a sole portion comprising a sole bottom end, a top portion opposite the sole portion, a heel portion, a toe portion opposite the heel portion, a rear portion, a front portion opposite the rear portion, the front portion comprising a strike face;
- and
- a hosel;
- a shaft sleeve insertable into the hosel and configured to couple a golf club shaft with the hosel;
- and
- a securing fastener configured to couple to a sleeve bottom end of the shaft sleeve to secure the shaft sleeve in the hosel:
- wherein:
- the hosel comprises a hosel bore configured to receive the shaft sleeve;
- the shaft sleeve comprises:
- a shaft bore configured to receive an end of the golf club shaft;
- a shaft sleeve body comprising a sleeve outer wall;
- a shaft sleeve cap configured to be coupled with the sleeve body;
- a sleeve top end;
- a sleeve bottom end;
- a sleeve axis extending longitudinally between the sleeve top end and sleeve bottom end;
- the shaft sleeve body further comprising:
- a first coupler protruding from the sleeve outer wall;
- a second coupler protruding from the sleeve outer wall;
- a third coupler protruding from the sleeve outer wall;
- and
- a fourth coupler protruding from the sleeve outer wall;
- the first coupler comprising a first arcuate surface curved throughout, the first coupler;
- the second coupler comprising a second arcuate surface curved throughout the second coupler;
- the third coupler comprising a third arcuate surface curved throughout the third coupler;
- the fourth coupler comprising a fourth arcuate surface curved throughout the fourth coupler;
- the shaft bore further comprising a shaft bore axis;
- wherein the shaft sleeve outer wall and shaft bore are non-coaxial.

- a second coupler protruding from the sleeve outer wall;
- a third coupler protruding from the sleeve outer wall;
- and
- a fourth coupler protruding from the sleeve outer wall;
- wherein:
- the shaft bore comprises a shaft bore axis;
- the first coupler comprises a first arcuate surface curved throughout the first coupler;
- the second coupler comprises a second arcuate surface curved throughout the second coupler;
- the third coupler comprises a third arcuate surface curved throughout, the third coupler;
- the fourth coupler comprises a fourth arcuate surface curved throughout the fourth coupler;
- and
- the shaft receiver comprises:
- a fifth coupler indented into the receiver inner wall;
- a sixth coupler indented into the receiver inner wall;
- a seventh coupler indented into the receiver inner wall;
- and
- an eighth coupler indented into the receiver inner wall;
- the fifth coupler comprises a fifth arcuate surface curved throughout the fifth coupler;
- the sixth coupler comprises a sixth arcuate surface curved throughout the sixth coupler;
