- Referring to
FIG. 1 , agolf shaft mount 10 is illustrated. As will be explained more fully below, thegolf shaft mount 10 permits agolf club shaft 12 and agolf club head 14, each potentially from different manufacturers and having different sizes and dimensions, to be mounted to each other in a removable and/or temporary fashion. Therefore, for example, specialty golf shops can assemble, disassemble, and reassemble differentgolf club shafts 12 and differentgolf club heads 14 to each other to customize clubs for a customer. As such, the customer can try the selected combination prior to purchase. Should the customer approve of the assembled components, thegolf shaft mount 10 is more than sufficient to maintain thegolf club shaft 12 and thegolf club head 14 secured together permanently for use on a golf course. As shown inFIG. 1 , thegolf shaft mount 10 comprises ahosel adapter 16 and ashaft sleeve 18. - The
hosel adapter 16 includes afirst connector 20, a reduceddiameter portion 22, ashoulder 24, and astub shaft 26. Thefirst connector 20 is, in a preferred embodiment, a threaded bore axially formed in thehosel adapter 16. In an exemplary embodiment, thefirst connector 20 is a threaded bore having a thread size of ¼-20. - The reduced
diameter portion 22, as shown inFIG. 1 , is interposed between theshoulder 24 and thestub shaft 26. The reduceddiameter portion 22 is, in a preferred embodiment, a circumferential groove formed in thehosel adapter 16. The reduceddiameter portion 22 is sized and dimensioned to receive and secure an o-ring 28. When installed, the o-ring 28 is seated within the reduceddiameter portion 22 and generally abuts theshoulder 24. The o-ring 28 can be made of a variety of materials such as, for example, rubber. - The
stub shaft 26 is sized and dimensioned to be received in an axially-bored neck portion of thegolf club head 14 known as ahosel 30. In a preferred embodiment, thestub shaft 26 includes one ormore grooves 32. Thegrooves 32 provide a receptacle for epoxy as well as promote a more even distribution of epoxy. Thegrooves 32 also ensure better and proper securement between thehosel adapter 16 and thegolf club head 14. Thegrooves 32 can be formed on thestub shaft 26 in a variety of patterns such as, for example, in a helical, spiral and/or corkscrew pattern as illustrated inFIG. 1 , in a circumferential or concentric circle pattern, in an axially-aligned pattern, and the like. The varying patterns of thegrooves 32 can be chosen based on differing construction objectives such as, for example, removing undesirable weight, permitting an increase amount of epoxy, granting the epoxy better coverage, and more securely holding theclub head 14. If desired, all or a portion of thestub shaft 26 can be abraded to further promote securement between thehosel adapter 16 and thegolf club head 14. - In an exemplary embodiment, the
shoulder 24 has a diameter of about 0.400 of an inch, the reduceddiameter portion 22 has a diameter of about 0.313 of an inch, and the stub shaft 36 (excluding the grooves 32) has a diameter of about 0.375 of an inch. Therefore, as shown inFIG. 1 , theshoulder 24 generally has a greater diameter than thestub shaft 26 and, in turn, thestub shaft 26 has a greater diameter than the reduceddiameter portion 22. - The
shaft sleeve 18 includes abore 34, acentral portion 36, aseating flange 38, and asecond connector 40. Thebore 34, which is cylindrical and axially-aligned with theshaft sleeve 18, is sized and dimensioned such that the shaft sleeve can be slideably received onto thetip end 42 of thegolf club shaft 12. As illustrated inFIG. 1 , thebore 24 can be tapered proximate the bottom to better facilitate insertion of thetip end 22 of thegolf club shaft 12 as well as provide a reservoir for epoxy. - The
central portion 36 is interposed between the seatingflange 38 and thesecond connector 40. In a preferred embodiment, thecentral portion 36 is slightly tapered such that the diameter of the central portion proximate thesecond connector 40 is just less than the diameter of the central portion proximate theseating flange 38. This minor taper permits thecentral portion 36 of the shaft sleeve to be easily and eventually snugly received within thehosel 30 of thegolf club head 14. - The
seating flange 38 is an integrally formed portion of theshaft sleeve 18 dimensioned to engage with and/or seat on atop surface 44 of thehosel 30. At least a portion of theseating flange 38 possesses a diameter greater than the diameter of thecentral portion 36. Therefore, while thecentral portion 36 can be slid into theopening 46 at the distal end of thehosel 30, theseating flange 38 cannot. In a preferred embodiment and as illustrated inFIG. 1 , theseating flange 38 is a frustoconical portion of theshaft sleeve 18 that diminishingly tapers as the seating flange extends away from thesecond connector 40. Theseating flange 38 or other portions of thegolf shaft mount 10 can include a wrench flat adapted to receive a wrench such that the golf shaft mount can be rotatably driven as well known by those skilled in the art. - The
second connector 40 is releasably securable and/or engageable with thefirst connector 20. In a preferred embodiment, thesecond connector 40 is a threaded shaft formed on theshaft sleeve 18 with a thread size similar to and/or correspondingly matching that of thefirst connector 20. As such, the first andsecond connectors second connector 40 is a threaded shaft having a thread size of ¼-20. As those skilled in the art will recognize, the first andsecond connectors hosel adapter 16 could include a threaded shaft similar to thesecond connector 40 and theshaft sleeve 18 could include a threaded bore similar to thefirst connector 20. - In an exemplary embodiment, the
central portion 36 has a diameter that tapers from about 0.400 of an inch near theseating flange 38 to about 0.397 of an inch near thesecond connector 40. Also in an exemplary embodiment, theseating flange 38 has a diameter of about 0.525 of an inch. Therefore, as shown inFIG. 1 , theseating flange 38 generally has a diameter greater than a diameter of thecentral portion 36. - The
golf shaft mount 10 ofFIG. 1 can be installed and/or incorporated into an assembled golf club 48 (FIGS. 2 and 3 ) as follows. First, the o-ring 28 is fitted onto thehosel adapter 16 until the o-ring is positioned within the reduceddiameter portion 22. Thereafter, an ample portion of epoxy is inserted into theopening 46 of thehosel 30 and/or onto thestub shaft 26 and in thegrooves 32 of thehosel adapter 16. With the epoxy satisfactorily distributed, thehosel adapter 16 is inserted,stub shaft 26 first, into theopening 46 until theuppermost surface 50 of thehosel adapter 36 is beneath thetop surface 44 of thehosel 30. In a preferred embodiment, thehosel adapter 16 is inserted into theopening 46 until theuppermost surface 50 is positioned approximately one inch below thetop surface 44. - Since the o-
ring 28 is sized and dimensioned to correspond to theopening 46 in thehosel 30, the o-ring engages theinner wall 52 of the hosel to draw the epoxy, much like a squeegee, downwardly into the hosel. As such, theinner wall 52 of thehosel 30 above theshoulder 24 on thehosel adapter 16 is generally wiped free (or substantially free) of epoxy. The epoxy that is driven below theshoulder 24 is able to distribute over and around thestub shaft 26 and within thehosel 30. Such distribution of epoxy is encouraged and aided by thegrooves 32. - After the epoxy has dried and/or cured and the
hosel adapter 16 is secured within thehosel 30, theshaft sleeve 18 is inserted,second connector 40 first, into theopening 46 of thehosel 30. In a preferred embodiment, the threaded first andsecond connectors second connectors seating flange 38 firmly abuts with and/or seats upon thetop surface 44 of thehosel 30. In this condition, thegolf club shaft 12 andgolf club head 14 are mounted together as illustrated inFIG. 3 such that thegolf club 48 can be tested, used, and the like. Notably, when thegolf shaft mount 10 is incorporated within thegolf club 48, the assembled golf club is aesthetically pleasing to a user. - When the first and
second connectors golf club shaft 12 relative to thegolf club head 14. To augment this result, for right-handed golfers and right-handed golf clubs, the threading on the first andsecond connectors - Should it be desired, the
golf club shaft 12 and thegolf club head 14 can be disengaged from each other by uncoupling the first andsecond connectors second connectors - Further, since the
bore 34 in theshaft sleeve 18 and thehosel adapter 16 can be constructed to have one of several different diameters, differently sized golf club shafts can be coupled with, and later uncoupled from, differently sized golf club heads. A plurality ofshaft sleeves 18 andhosel adapters 16 having various dimensions, butuniversal connectors - As illustrated in
