Dependent claims

A golf coupling mechanism between a golf club head and a golf club shaft, the golf coupling mechanism comprising:

a shaft sleeve configured to be coupled to an end of the golf club shaft and a hosel;
wherein:
the shaft sleeve comprises:
a shaft bore configured to receive the 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 shaft sleeve;
a coupler set 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 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;
wherein the first arcuate surface, second arcuate surface, third arcuate surface, and fourth arcuate surface are symmetric in profile;
wherein the shaft bore is further configured to receive and retain a tip weight;
and
wherein the tip weight is disposed between a bottom surface of the shaft bore and the end of the golf club shaft.

17 more elements

A golf coupling mechanism for a golf club head and a golf club shaft, the golf coupling mechanism comprising:

a shaft sleeve configured to be coupled to an end of the golf club shaft and a hosel;
a shaft receiver of the golf club head configured to receive the shaft sleeve;
wherein:
the shaft sleeve comprises:
a shaft bore configured to receive the 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 shaft sleeve;
a coupler set 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 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;
the seventh coupler comprises a seventh arcuate surface curved throughout the seventh coupler;
the eighth coupler comprises an eighth arcuate surface curved throughout the eighth coupler;
wherein the coupler set is asymmetric in profile such that the first coupler is longer at a first part of the sleeve body outer wall of the shaft sleeve than the second, third, and fourth couplers.
