ADJUSTABLE GOLF PU'I'IER This invention relates to a golf putter and more particularly to an improved shaft arrangement for a golf putter which permits the user to adjust the putter so as to obtain maximum control and comfort.
Conventional golf putters are provided with a straight shaft with a grip at its upper end. With such a putter the golfcrs hand must be held in an awkward position and it is difficult to properly align the striking face of the putter with the ball and especially difficult to maintain this alignment when swinging the putter. Since, with the conventional straight shaft, the head of the putter is held close to the users body it is difficult to accurately sight from the striking face of the putter to the hole into which the golf ball is to be driven. Another disadvantage of conventional putters is that the shaft is of a fixed length and, while this difficulty is partially overcome by manufacturing putters having different lengths shafts, it is not feasible to manufacture putters of a sufficient variety of lengths to be ideally suitable for all golfers. The fixed lengths of the putter shafts also necessitate the stocking of a great number of putters by golf supply shops.
It is the primary object of the present invention to provide an improved golf putter in which the putter may be held in a comfortable position by the user. A further object of the invention is a provision of a golf putter which enables the user to accurately sight from the putter face to the hole and to accurately align the putter face with the golf ball. It is also an object of the present invention to provide an improved golf putter in which the length of the shaft may be readily adjusted to suit the needs of the individual golfer.
The above and other objects and advantages of the invention will become apparent upon consideration of the following specification and the accompanying drawing wherein there is shown a preferred embodiment of the invention.
In the drawing:
FIG. 1 is a pictorial view showing a golfer using the putter of my invention;
FIG. 2 is a side elevational view of the golf putter of my invention;
FIG. 3 is a sectional view taken along the line III-III of FIG.
FIG. 4 is a sectional view taken along the line IV-IV of FIG. 3;
FIG. 5 is a sectional view taken along the line V-V of FIG. 2', and
FIG. 6 is a sectional view of the head portion of the putter of my invention, taken along the line VI--VI of FIG. 2.
Referring first to FIGS. 2-6, the golf putter of my invention will now be described. The putter 10 consists of a handle portion 11, a shaft 12, and a head portion 13. The handle or grip portion l I may be constructed ofleather or rubber in the conventional manner to provide a gripping surface for the golfers hands. The grip II is secured to the end of the upper portion 14 of the shaft 12. It should be noted that the grip 11 is secured to the shaft portion 14 at an angle of slightly less than 180. The upper shaft portion 14 is connected to an intermediate shaft portion 15 by an adjustable connection 16 to be described in more detail below. The lower end of the intermediate shaft section 15 is telescopically connected to a lower shaft portion 17 by a connection 18, also to be described in more detail below. The lower end of the shaft section 17 is ridgedly secured to the putter head 13.
As will be seen in FIG. 3, the connection 16 consists of a disc-like member 19 secured to the upper shaft portion 14, a cap-like member 20 secured to the intermediate shaft portion 15 and a bolt 21 passing through the member 19 and received in a threaded hole 22 of the member 20. The mating surfaces of the members I9 and 20, which are normal to the axis of the bolt 2l, are provided with radially extending ribs or corrugations 23. The member 19 is also provided with an angular recess 24 to reduce the weight of a member. The bolt 21 is provided with an enlarged head 27 which completely covers the outer face of the member 19 so as to exert uniform clamp ing force to the member 19 when the bolt 21 is tightened. The
circumference of the head 27 of the bolt 21 may be provided with a serrated edge to enable the user to securely grip the head 27 when tightening or loosening the bolt 21. The outwardly projecting lugs 25 and 26 of the members 19 and 20, respectively, are of hexagonal cross-section and are thus received in the hexagonal crowsectional bores of the shaft portions 14 and 15, respectively, without twisting.
The connection 18, illustrated in FIG. 5, consists of an arrangernent for tightly clamping the telescoping tube portions 15 and 17. The intermediate shaft member I5 is formed of a round tube having a hexagonal bore. The lower shaft portion 17 is formed of a length of round tubing of a diameter sufficiently small as to permit the lower shaft portion 17 to move freely in the bore of the intermediate shaft portion 15. The upper end of the tube forming the lower shaft portion I7 is provided with an enlarged portion 28 which makes a close sliding fit with the hexagonal bore of the intermediate shaft portion 15. The end 28 of the portion I7 is of hexagonal crosssection and may be formed by forging the upper end of the tube 17 or maybe a separate member rigidly secured to the ends of the tube 17. In either event, the ends 28 permits axial movement between the shaft members 15 and 17 while preventing any rotational movement between these members. The lower end of the intermediate shah member 15 is externally threaded. A collar 30 is screwed on to the threading portion 29 of the intermediate shaft portion 15. The lower end of the tube 15 is provided with a 45 inwardly directed bevel 31. A metal washer 32 is positioned adjacent the bevel 31 and a rubber ring 33 is positioned between the washer 32 and the lower end 34 of the sleeve or collar 30. As the collar 30 is screwed on the threaded portion 29 of the intermediate shaft 15 the rubber ring 33 is compressed between the washer 31 and the end portion 34 of the collar 30. The axial compresing of the ring 32 causes the ring to exert a force radially against the lower shaft member 17, tightly clamping the members 15 and 17 together.
The head portion 13 of the putter, shown in FIG. 6, has a flat striking face 35 which is provided with a rubber insert 36 along the major portion of the face 35. Rearwardly of the face 35, the head portion 13 is provided with a raised portion 37 having a vertical hole 38 extending downwardly from its upper surface for receiving the prong of an aligning device 41, which may be of the type shown in my earlier application, Ser. No. 647,032, filed June I9, 1967, now U.S. Pat. No. 3,529,830, issued Sept. 22, l970. The hole 38 has a cross-sectional configuration such that the prong of the aligning device 4] may be inserted in only one position, thus assures the correct alignment of the device. The side 40 of the head portion I3 immediatcly adjacent the face 35 extends upwardly into the neck-like portion 39 and the lower end of the tube 17 is rigidly secured to this projection 39. By attaching the shaft 17 to the head 13 at a location close to the ball striking face 35, the weight of the rear portion 37 and the aligning device 4| is offset and the club retains a balanced feel.
As will be seen from FIG. I, the angled portion of the shaft 15 and the connecting neck 39 allow the head 13 of the putter to be positioned well forward of the golfer while yet allowing him to keep his hands close to his body, thus improving the golfers control of the movement of the putter. The connection 16 permits the golfer to vary the distance the head 13 is located in front of him by varying the angle between the upper portion 15 and the intermediate portion 16 of the shaft. This connection also permits the golfer to vary the angle at which he grips the putter to achieve the most comfortable position. The connection 18 also aids the golfer in holding the club at the position which is most comfortable and which gives the greatest control by permitting him to adjust the length of the putter shaft. Since the head 13 of the putter is positioned well forward of the golfer's feet, the golfer may easily sight downwardly to the head 13 and to the hole to which the ball is to be putted.
