Wheeler, 2502 Tulane Ave., Alamogordo, N. Mex. 88310 Filed June 8, 1967, Ser. No. 644,615 Int. Cl. A63b 53/02, 53/16 US. Cl. 273-81.2 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates to improvements in golf clubs and separable components therefor. Golf clubs in current use are most frequently constructed of interfitting components secured as a rigid integral unit and afford little or no adjustment to meet the playing requirements of the user or users, thus necessitating a separate club of different shaft length and blade or head configuration for various use requirements of one or more players. Attempts have been made to provide interchangeability and adjustment of the club head on the shaft and adjustment of the shaft length during the course of play, but these have not proved entirely satisfactory for all applications and player requirements and particularly do not provide added utility for putters of any significance.

Accordingly, an object of this invention is to provide a simple, durable, efficient and easily adjustable putter assembly permitting two or more users to selectively vary grip position and blade configuration and weight to his preference for given periods of play.

Another object of this invention is to provide a golf club assembly having interchangeable component parts arranged for easy assembly and disassembly and adjustment so as to afford a given user of a putter a selection of sizes, configurations, weights and materials for a period of play.

Still another object of this invention is to provide a novel golf club in which a variety of sizes, shapes and Weights of heads may be assembled and disassembled on the same shaft of a golf club assembly.

It is still another object of this invention to provide a putter assembly wherein the effective length of the shaft between grip and club head may be lengthened or shortened as required by the user either before or during a period of play. 1

Referring now to the drawings, a club assembly embodying my invention is shown in FIG. 1 to include anintermediate shaft 2 with a grip orhandle 3 mounted on an upper end of the shaft, an upper fastening or lockingmember 4 locking the grip to the shaft with one of a plurality of heads '5 mounted on the lower end of the shaft and a lower fastening orlocking member 6 locking the head against movement on the shaft.

The grip 3- as more fully illustrated in FIGS. 3 and 4 comprises an elongated body which may be provided with an external surface of various known shapes and materials suitable for a firm grasping by the user. Thegrip 3 includes an internal aperture of a greater diameter than the assocaited upper portion of the shaft so as to telescope thereon for extension and retraction movements to vary the effective length thereof. In a preferred form the internal surface of thegrip 3 is provided with a threaded portion 8 and the upper portion of the shaft is provided with a mating threadedportion 9 so that the handle orgrip 3 will move along the shaft to extend or retract in selected increments as desired by rotating one with respect to the other. In this manner, the increment or amount of movement of the handle or grip with respect to the shaft may be closely regulated.

- Theupper fastening member 4 comprises a generally hollow body having an internal bore 4a of a greater diameter than the lower portion of the handle and upper portion of the shaft so as to fit on or telescope thereover (FIG. 3). Internal threads 11 are provided inmember 4 which thread on an external threadedportion 12 of the grip .3. The internal bore of the fasteningmember 4 includes atapered portion 13 on its inner surface below the threaded portion 11 which coacts with atapered portion 14 adjoining the lower end of the grip andelongated slots 15 preferably four in number extending lengthwise of the tapered portion.

As best seen in FIGS. 3 and 4 when the fasteningmember 4 is threaded upwardly on thegrip 3, thetapered portions 13 onmember 4 engage or wedge against thetapered portion 14 of the grip so as to force adjoining surfaces of the grip against surfaces of the shaft to hold 3 or lock the grip against further movement with respect to the shaft. The external surface of thefastening member 4 may be provided with tapered end portions and be knurled as shown at 4b or provided with a similar irregular external surface for ease in threading on the handle.

As shown in FIGS. 6 and 7, the club head has anupstanding shank portion 18 arranged in a quick coupling and decoupling relation to the lower end of theshaft 2 by means of an aperture orfemale portion 19 of a joint being provided in the upper end of theshank portion 18 which receives an extended ormale portion 20 having a hollow bore carried by the lower end of the shaft which is inserted intoaperture portion 19. In a preferred form, themale portion 20 is of a multisided configuration and hexagonal in section (FIG. 7) with corresponding shaping of theaperture 19 to prevent rotational movement of thehead 5 on theshaft 2. This arrangement provides a quick detachment of the head on the shaft and consistent alinement of the head thereon for ease in assembly and disassembly and facilitates the use of multiple heads on the same shaft.

Thelower fastening member 6 comprises a generally hollow body having an internal bore 6a of greater diameter than the lower portion of the shaft and the shank portion of the head so as to fit on or telescope thereover (FIG. 6).Internal threads 22 are formed on the inner surface of the fasteningmember 6 which mate and thread downwardly on an external threadedportion 23 of theshank 18.

The lower end portion ofshaft 2 is provided with a flange orrim 24 of greater diameter than theshaft 2 or extendedportion 20 which has a flexible washer-like member 25 of similar diameter fitted on the shaft and seated on theflange 24. Between the upper end of the fasteningmember 6 and its threadedportion 22 there is provided ashouldered portion 27 which engages the upper surface of the flexible member so as to force it againstflange 24 when the fasteningmember 6 is rotated so as to thread downwardly over theshank portion 18 and lock thehead 5 against movement on the shaft. The external surface of the fasteningmember 6 may have tapered end portions and a knurled portion 61; as doesmember 4 previously described for ease in such threading. An alternative coupling or fitting arrangement for connecting the head to the lower portion of the shaft may be provided in the form of a spring loaded type of quick disconnect.

Alternative forms of club heads having different shapes and weights of the putter type are shown in FIGS. which are suitable for interchangeable attachment toshaft 2 in the manner similar tohead 5 previously described to illustrate the plurality of heads which may be used with a single shaft.Head 30 as shown in FIGS. 10 and 11 includes ashank portion 31 offset along its length and secured to the top surface and between the ends of alower portion 32 of generally square section.Head 33 shown in FIGS. 12 and 13 includes a substantiallystraight shank portion 34 secured to a side of and intermediate the ends of alower portion 35 of generally square section and of greater section thanportion 32 to provide additional weight. Head 36 as shown in FIGS. 14 and 15 includes ashank portion 37 offset along its length and secured at the lower end to the rearward portion of the top surface of alower portion 38 of generally rectangular section. The upper end of each of the shank portions of each of theseheads 30, 33 and 36 is provided withexternal threads 23 and an internal bore orfemale joint portion 19 of the same construction as illustrated in FIG. 6 for slidable attachment to the lower end ofshaft 2.

From the foregoing, it is apparent that a golf club assembly features of the present invention will provide a wider selection of putter sizes with less expense and is particularly suitable for persons who wish to share the use of a set of golf clubs at different times, such as for example, a husband and wife. A selected size, weight and angle of golf club head may be easily and quickly secured to the shaft and its length adjusted to accommodate the user. The necessity of separate shafts and handles which add to the cost and inconvenience of carriage is thus eliminated. In addition, before and after use the golf club may be easily and quickly assembled and disassembled for carriage in a comparatively smaller case than the usual rigid integral clubs It is understood that various parts of the golf club assembly as above described may be constructed of a variety of materials such as metals, alloys, leather and the like and although the metal putter type heads have been shown, various forms of woods may be similarly formed and particularly the grip adjustment is suitable for the wood variety.

Although the invention is described with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and numerous changes in the details of construction, arrangement of parts and selection of materials as well as a change in shaping may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
