Abstract
Abstract A golf club includes a head, hosel, grip, and shaft. At the time of attachment of the hosel to the club head, the club head is positionable relative to the shaft at a plurality of angles, of not less than 10 degrees in relation to the shaft and hosel assembly. The present invention permits the golf club to be configured to fit the golfer with respect to total club length and angular relation of club head to shaft and hosel, for a right handed or left handed golfer and to be assembled to fit the individual golfer in accordance with height, stature and personal preference of the individual. The design permits the sole of the club head to remain substantially flat with respect to the putting surface, and is consistent with the "USGA Rules of Golf."

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
249 words
A golf club comprising: a shaft and hosel assembly, said shaft defining a longitudinal shaft axis and said hosel including a first leg portion and a second leg portion integral with said first leg portion, said first leg portion defining a hosel axis parallel to and offset from said shaft axis and having a distal end with a first connection, said second leg portion connecting said first leg portion to said shaft; and a head having a toe end, a heel end, a ground engaging surface, a rear side, a flat, ball-striking face extending between said toe end and said heel end and defining a first plane parallel to said shaft axis and said hosel axis, and a second connection for mating with said first connection to secure said head to said shaft and hosel assembly, said second connection extending perpendicular to said ball-striking face from a point on said rear side centered between said toe end and said heel end and defining an axis of rotation for said shaft in a second plane parallel to said first plane, said axis of rotation being perpendicular to said ball-striking surface, one of said first and second connections being a socket having a tapered cylindrical interior surface and the other of said first and second connections being a tapered pin having a tapered cylindrical exterior surface for mating with said interior surface, whereby said ball-striking face may remain perpendicular to the ground with rotation of said shaft in said second plane.
Claim 2
Dependent Claim
249 words
A golf club comprising: a shaft and hosel assembly, said shaft defining a longitudinal shaft axis and said hosel including a first leg portion and a second leg portion integral with said first leg portion, said first leg portion defining a hosel axis parallel to and offset from said shaft axis and having a distal end with a first connection, said second leg portion connecting said first leg portion to said shaft; and a head having a toe end, a heel end, a ground engaging surface, a rear side, a flat, ball-striking face extending between said toe end and said heel end and defining a first plane parallel to said shaft axis and said hosel axis, and a second connection for mating with said first connection to secure said head to said shaft and hosel assembly, said second connection extending perpendicular to said ball-striking face from a point on said rear side centered between said toe end and said heel end and defining an axis of rotation for said shaft in a second plane parallel to said first plane, said axis of rotation being perpendicular to said ball-striking surface, one of said first and second connections being a socket having a tapered cylindrical interior surface and the other of said first and second connections being a tapered pin having a tapered cylindrical exterior surface for mating with said interior surface, whereby said ball-striking face may remain perpendicular to the ground with rotation of said shaft in said second plane.
Claim 3
Dependent Claim
65 words
A golf club in accordance with claim 1 wherein said shaft and hosel assembly is rotatable with respect to said head, about said axis of rotation, to allow for orientation of the shaft with respect to the head to accommodate both right handed and left handed users and to allow the angle between the shaft and the head to be custom set for the user.
Claim 4
Dependent Claim
67 words
A golf club in accordance with claim 2 further comprising an angular stop in the form of a protrusion extending from said rear side, parallel to and spaced from said second connection, opposite said ground engaging surface, said angular stop preventing said angle from being set less than 10 degrees either side of a line extending perpendicular from said ground engaging surface through said axis of rotation.
Claim 5
Dependent Claim
37 words
A golf club in accordance with claim 3 further comprising means on said angular stop defining a visible line for alignment of a golf ball resting against said striking surface and centered on said axis of rotation.
Claim 6
Dependent Claim
27 words
A golf club in accordance with claim 1 further comprising locking means for permanently locking the position of said shaft and hosel assembly relative to said head.
Claim 7
Dependent Claim
52 words
A golf club in accordance with claim 5 wherein said locking means comprises a headed screw, a threaded bore in said pin along said axis of rotation and a circumferential shoulder defined by said socket whereby said headed screw is drawn flush against said shoulder upon being threaded into said threaded bore.
Claim 8
Dependent Claim
24 words
A golf club in accordance with claim 6 further comprising a recess in said socket, said recess forming said shoulder as a bottom surface.
Claim 9
Dependent Claim
27 words
A golf club in accordance with claim 7 further comprising a cap covering said recess and solidified resin within said recess between said cap and said screw.
Claim 10
Dependent Claim
16 words
A golf club in accordance with claim 6 wherein said headed screw is a one-way screw.
Claim 11
Dependent Claim
50 words
A golf club in accordance with claim 1 wherein said rear side defines a rear face and has a recess defining a recessed face parallel to said rear face, said second connection extending from said recessed face and terminating at a point between said recessed face and said rear face.
Claim 12
Dependent Claim
47 words
A golf club in accordance with claim 1 wherein the offset between said shaft axis and said hosel axis provides a line of sight along said shaft to the center of a USGA dimensioned golf ball abutting said ball-striking face and aligned with said axis of rotation.
Claim 13
Dependent Claim
47 words
A golf club in accordance with claim 4 wherein the offset between said shaft axis and said hosel axis provides a line of sight along said shaft to the center of a USGA dimensioned golf ball abutting said ball-striking face and aligned with said axis of rotation.
Claim 14
Dependent Claim
77 words
A golf club in accordance with claim 5 wherein said permanent locking means comprises a hard steel wire compressed between said tapered cylindrical interior surface and said tapered cylindrical exterior surface, said steel wire forming an indentation in both said tapered cylindrical interior surface and said tapered cylindrical exterior surface, whereby the steel wire provides an enhanced bond between said first and second connections to prevent rotation of the hosel and shaft assembly relative to the head.
Claim 15
Dependent Claim
31 words
A golf club in accordance with claim 5 wherein said permanent locking means comprises a hole extending diametrically through said pin and said socket and a pin fitted within said hole.
