Abstract:
An adjustable golf club is disclosed having a hosel with a spherical section and positioning linkage that allows the face angle of the head to be changed without changing the lie angle or rotating the shaft around its axis. The hosel is fixed in place by tightening the spherical surface of a compression nut against the spherical section of the hosel and a receiving compression cup with matching spherical surface radiuses, along with a slotted rotation prevention section consisting of two flat surfaces, a threaded linkage engaging the lower hosel piece and anchored to a tube attached to the skirt of the head. The linkage is used to threadably position the angle of the hosel piece. The invention also provides a quick and easy way to remove and replace the hosel piece along with the shaft for additional customization of the club.
