Abstract

A system for adjusting alignment of a golf club head includes a club shaft having a proximal end and an opposing distal end, with a hosel fitting fixedly secured to the distal end of the club shaft. A neck is rotationally coupled to the hosel fitting at a first end and a club head is coupled to the second end of the neck. The hosel fitting includes a reference line and the neck includes a series of angle index lines. The angle of the club face is adjusted by selectively aligning a singled angle index line with the reference line.

Claims (38)

1 . A system for adjusting alignment of a golf club head, the system comprising:

a) a club shaft having a proximal end and an opposing distal end;

b) a hosel fitting fixedly secured to said distal end of said club shaft;

c) a neck having a first end and a second end, wherein said first end is rotationally coupled to said hosel fitting; and

d) a club head coupled to said second end of said neck, wherein said club head comprises a fitting head having a body portion defining a club face and a tubular portion extending perpendicularly rearward from said club face, wherein said club face includes an aperture in communication with an open interior of said tubular portion, and wherein said open interior is dimensioned to receive a laser unit therein, wherein powering of said laser unit causes a light beam to extend outwardly of said club face through said aperture.

2 . The system in accordance with claim 1 , wherein rotation of the neck about said hosel fitting adjusts an angle of said club face relative to a vertical axis defined by said club shaft.

3 . The system in accordance with claim 2 , wherein said hosel fitting includes one of a reference line or a series of angle index lines, and wherein said neck includes the other of said reference line or said series of angle index lines, whereby said angle is selectively adjusted by selectively aligning a single angle index line with said reference line.

4 . The system in accordance with claim 3 , wherein each successive angle index line within said series of angle index lines corresponds to 1 degree of rotation of said club face.

5 . The system in accordance with claim 3 , wherein said neck is secured to said hosel fitting through an interference fit to thereby prevent further rotation of said neck.

6 . The system in accordance with claim 1 , wherein said club head includes a raised sight line extending upwardly of a plane formed by a top edge of said club face, wherein said raised sight line is perpendicular to said club face.

7 . The system in accordance with claim 6 , wherein a forward end of said raised sight line terminates a spaced distance from said club face.

8 . The system in accordance with claim 6 , wherein said raised sight line extends perpendicularly from the midpoint of said top edge of said club face.

9 . The system in accordance with claim 1 , wherein said proximal end of said club shaft includes a grip having a circular cross section.

10 . The system in accordance with claim 9 , wherein said grip has a tapered length wherein a first portion of said grip proximate said proximal end of said club shaft has a smaller diameter than a second portion of said grip distal said proximal end of said club shaft.

11 . The system in accordance with claim 1 , wherein said body portion includes a pair of neck receiving apertures, wherein a first aperture of the pair of apertures is configured to receive said neck portion to create a right-handed golf club and wherein a second aperture of the pair of apertures is configured to receive said neck portion to create a left-handed golf club.

12 . The system in accordance with claim 1 , wherein one or both of said body portion and said tubular portion include a threaded aperture portion to threadably couple said laser unit to said fitting head.

13 . The system in accordance with claim 1 , wherein said powering of said laser is via remote control.

14 . A method for adjusting the alignment of a golf club head, the method comprising:

a) providing a golf club having a fitting head mounted thereon, the fitting head comprising:

i) a club shaft having a proximal end and an opposing distal end;

ii) a hosel fitting fixedly secured to said distal end of said club shaft;

iii) a neck having a first end and a second end, wherein said first end is rotationally coupled to said hosel fitting; and

iv) a club head coupled to said second end of said neck, wherein said club head has body portion defining a club face and a tubular portion extending perpendicularly rearward from said club face, wherein said club face includes an aperture in communication with an open interior of said tubular portion, and wherein said open interior is dimensioned to receive a laser unit therein, wherein powering of said laser unit causes a light beam to extend outwardly of said club face through said aperture,

b) positioning a golfer a predetermined distance away from a stationary target;

c) allowing the golfer to align the golf club to the stationary target;

d) powering the laser to emit a laser beam from the golf club toward the stationary target to establish a golfer alignment value;

e) determining an amount of deviation of the golfer alignment value from the stationary target;

f) rotating said neck on said hosel fitting to negate the amount of deviation whereby said laser beam coincides with said stationary target; and

g) securing said neck to said hosel fitting to prevent further rotation of said neck.

15 . The method in accordance with claim 14 , further comprising the steps of:

a) removing said fitting head from said neck after securing said neck to said hosel filling (step g); and

b) securing a desired club head to said neck.

16 . A golf club head comprising:

a) a body portion defining a club face;

b) a tubular portion defining an open interior extending perpendicularly rearward from said club face, wherein said open interior is dimensioned to receive a laser unit therein;

c) an aperture defined within said club face and in communication with said open interior of said tubular portion;

d) a battery compartment defined within said body portion and extending perpendicularly to said tubular portion, wherein the battery compartment is configured to receive a battery therein, wherein the battery is configured to be electrically connected to the laser wherein powering of the laser unit via the battery causes a light beam to extend outwardly of said club face through said aperture.

17 . The golf club head in accordance with claim 16 , wherein the body portion further defines at least one lateral adjustment aperture adapted to threadably receive a corresponding set screw therein, wherein alignment of the laser unit is adjustable via said set screw.
