Abstract

A golf club fitting apparatus and method utilizes a number of different club heads, the club heads having hosel or shaft receiving bores at different angles and securing devices for releasably securing a hosel at the lower end of a golf club shaft in the bore, and a number of different shafts. The heads have different parameters such as peripheral weighting, center of gravity, and face area in addition to different bore angles. A player can select various different head and shaft combinations to test. To test each combination, the hosel at the end of the shaft is inserted in the bore, and releasably secured in position. The player then tries it out. The shaft is released, and a new combination is tested in the same manner, until an optimum fit for that particular player is found.

Claims

1. A golf club fitting apparatus, comprising:

a plurality of different golf club heads;

each club head having an outer surface comprising a front face, a rear wall, an upper wall, a lower wall, a heel and a toe;

the head having a bore extending inwardly from said upper wall adjacent said heel at a selected angle, the club heads including heads having bores at different angles relative to the club head;

at least one hosel tube having a lower end portion for engagement in the bore in a selected head;

a golf club shaft having a lower end portion secured in said hosel tube; and

each of said heads including

a releasable securing device adapted to releasably secure the lower end portion of the hosel tube in the bore of the selected head.

2. The apparatus as claimed in claim 1, wherein the lower end portion of the hosel tube has a roughened surface.

3. The apparatus as claimed in claim 1, including a plurality of different golf club shafts secured to hosel tubes for selective connection to a selected head.

4. The apparatus as claimed in claim 1, wherein each hosel bore has an adjustable periphery and the securing device comprises at least one clamping screw for reducing the periphery of said bore to grip the lower end portion of an inserted hosel tube.

5. The apparatus as claimed in claim 4, wherein each hosel bore has a transverse slit projecting outwardly from the bore to the outer surface of said head, said slit having opposite flat faces, and the head has a second bore extending from said outer surface transverse to said slit through one of said flat faces for receiving said clamping screw and a third, threaded bore extending from said second flat face in alignment with said second bore for threaded engagement with said clamping screw to draw the flat faces together and reduce the periphery of said first bore.

6. The apparatus as claimed in claim 5, wherein the securing device comprises two clamping screws, the head having a pair of parallel bores extending from the outer surface transverse to said slit through one of said flat faces for receiving said clamping screw and a pair of threaded bores in said second flat face, each threaded bore being in alignment with a respective one of said parallel bores for threaded engagement with a respective one of said clamping screws.

7. The apparatus as claimed in claim 1, wherein the lower end portion of said hosel tube has a solid end plug having a threaded bore, said head having a through bore extending from the lower wall in alignment with said first bore and communicating with the lower end of said first bore, and said securing device comprises a retaining screw in said through bore for releasable threaded engagement in the bore in the end plug of a hosel tube in said first bore to hold the hosel tube in said bore.

8. The apparatus as claimed in claim 4, wherein said club head comprises a body having a downwardly facing recess and a separate sole plate secured in said recess forming the lower wall of said head, the body having a slit extending from an outer surface between said recess and said upper wall and transversely into said bore, said slit having opposing flat faces and said releasable securing device comprises at least one clamping screw to draw said faces together and reduce the periphery of said bore.
