Abstract
Abstract A golf club adapted for assembly/dissassembly includes a cylindrical coupler with a lower part inserted permanently in the lower hollow shaft and which has a shoulder abutting the top of the lower shaft. The upper part of the coupler has internal threading cooperating with external threads on a solid shaft inserted in the upper hollow shaft. A projection on the upper part of the coupler cooperates with a cut-out in the upper hollow shaft to provide alignment of the grip and head of the club when the solid shaft is screwed into the coupler by using a knob or shoulder on the upper end of the solid shaft that tightens against the grip.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
A golf club comprising: upper and lower tubular sections wherein said upper tubular section has a grip at one end and said lower tubular section has a head at one end requiring a predetermined alignment with said grip; a coupler including upper and lower parts, said lower part being inserted in said lower tubular section at the end opposite said head and said upper part being insertable in the lower end of said upper tubular section opposite said grip; a shaft inserted in said upper tubular section including exterior threading at its lower end and a shoulder at its upper end; said upper part of said coupler including interior threading cooperating with said exterior threading of the lower end of said shaft whereby coupling can be made by inserting said upper part of said coupler into the lower end of said upper tubular section and screwing said shaft into said coupler until said shoulder of said shaft is tight against said grip at the upper end of said upper tubular section; and aligning means including means integrally associated with said upper part of said coupler, and cooperating means associated with the lower end of said upper tubular section.
Claim 2
Dependent Claim
198 words
A golf club comprising: upper and lower tubular sections wherein said upper tubular section has a grip at one end and said lower tubular section has a head at one end requiring a predetermined alignment with said grip; a coupler including upper and lower parts, said lower part being inserted in said lower tubular section at the end opposite said head and said upper part being insertable in the lower end of said upper tubular section opposite said grip; a shaft inserted in said upper tubular section including exterior threading at its lower end and a shoulder at its upper end; said upper part of said coupler including interior threading cooperating with said exterior threading of the lower end of said shaft whereby coupling can be made by inserting said upper part of said coupler into the lower end of said upper tubular section and screwing said shaft into said coupler until said shoulder of said shaft is tight against said grip at the upper end of said upper tubular section; and aligning means including means integrally associated with said upper part of said coupler, and cooperating means associated with the lower end of said upper tubular section.
Claim 3
Dependent Claim
65 words
A golf club in accordance with claim 1 wherein: said integral means associated with said upper part of said coupler includes a raised projection; and said cooperating means associated with the lower end of said upper tubular section includes a cut-out in the lower end of said upper tubular section conforming to the shape of said raised projection on said upper part of said coupler.
Claim 4
Dependent Claim
19 words
A golf club in accordance with claim 2 wherein: said projection is circular; and said cooperating cut-out is U-shaped.
Claim 5
Dependent Claim
