Patent ID: 7736243

Claim:
A golf club attachment mechanism comprising: a hosel adapter configured to be located at a bottom of a hosel of a golf club head, the hosel adapter comprising a first slot coupler across a top portion of the hosel adapter; a shaft adapter configured to be located at an end of a golf club shaft, the shaft adapter comprising a second slot coupler, complementary to the first slot coupler, across a bottom portion of the shaft adapter; and a cap configured to circumscribe an exterior perimeter of a golf club shaft; wherein: the first slot coupler tapers across a top end of the hosel adapter, from a first end to a second end narrower than the first end of the first slot coupler; the second slot coupler tapers across a bottom end of the shaft adapter, from a first end to a second end narrower than the first end of the second slot coupler, and is complementary to the first slot coupler; the first slot coupler and the second slot coupler couple together within the hosel, when the shaft adapter is inserted into the hosel along a central-length axis of the hosel, to restrict a rotational movement of the hosel adapter relative to the shaft adapter; the first slot coupler and the second slot coupler are configured to decouple from each other within the hosel, when the shaft adapter is removed along the central-length axis of the hosel, to permit a separation of the golf club shaft from the golf club head; and the cap is configured to couple to a hosel of a golf club head, at least partially above the shaft adapter, to maintain the shaft adapter in a position within the hosel.
