Description

IMPROVEMENTS IN GOLF CLUBS
This invention relates to a golf club. Golf clubs vary in many different ways, e.g. in the shape of the club head, the stiffness . of the shaft, the so-called "swing weight" etc.. , and in general, the needs of each individual golfer are different. The problem hitherto has been that most shops are not able to stock a big enough range of clubs which an individual can try out and find the one that ideally suits him.
The present invention provides a golf club comprising a club head assembly, an elongate shaft assembly, a bore in the club head assembly for receiving one end of the shaft assembly, and releasable means for retaining the shaft assembly in position in the bore of the club head assembly with sufficient security to enable the temporarily assembled golf club to be used in practice, in which said releasable means comprises wedging means insertable into the club head ε.ssembly to engage the shaft assembly and wedge the shaft assembly into engagement with the bore, with means being provided for retaining the wedging means in the club head assembly.
By providing a golf club which can be assembled in a manner which is temporary, yet which achieves sufficient security to enable the club to be used in practice, the opportunity is given for individuals to try out as many different combinations of club head and shaft as they need to find the ideal combination for them before the club is εctually finished, and in this way, each individual is effectively able to have his clubs tailor made. In a more specific aspect of the invention there is provided a golf club of the kind comprising a club head assembly, an elongate shaft assembly, a bore in the club head assembly for receiving one end of the shaft assembly, and releasable means for retaining the shaft assembly in position in the bore.of the club head assembly with sufficient security to enable the temporarily assembled golf club to be used in practice, in which said releasable means comprises wedging means insertable into the club head assembly to engage the shaft assembly and wedge the shaft assembly into engagement with the bore, with means being provided for retaining the wedging means in the club head assembly, wherein the shaft assembly includes an elongate shaft and there is a cylindrical outer surface at said one end of the shaft assembly to engage the bore in the club head assembly, the axis of which outer surface lies at an angle with respect to the longitudinal axis of the shaft whereby the position of rotation of the shaft assembly in the bore determines the lie and face angle of the assembled club, and means is provided for holding the shaft assembly to the club head assembly in a selected one of a plurality of rotational positions in the bore. By way of example, an embodiment of the invention will now be described with reference to the accompanying drawings, in which:
Figure 1 is a part sectional exploded view showing the component parts of a golf club in accordance with the present invention, and
Figure 2 is a part sectional view of the assembled club.
The component parts of a golf club are seen in Figure 1 and include a club head assembly comprising a club head 10, which may be of wood, for example, or metal or plastics material, having a neck portion 12 into which an end of an elongate shaft assembly comprising a shaft 14 is fitted. A bore 10A is provided in the club head 10 to receive the end of the shaft assembly as seen in Figure 2. The diameter of the bore 10A is greater than the shaft diameter. The shaft assembly includes a cylindrical bush 16 which has a bore 16A therein to receive the end of the shaft 14. The bush 16 is permanently attached to the shaft 14, eg by adhesive. The outer cylindrical surface 16B of the bush 16, which in this case is of round cross-section is to engage the bore 10A in the club head 10.
Here, the bore 16A is drilled in the bush 16 such that the axis of the bore 16A lies at an angle with respect to the axis of the outer surface 16B of the bush 16. In Figure 1, this angle or "offset" is represented by angle a. This "offset" is to enable the lie and face angle of the club to be adjusted as desired by varying the rotational position of the bush in the bore of the club head. This arrangement is described in my earlier patent application GB-A-2197209, the disclosure of which is herein incorporated by reference.
The club head assembly includes a collar 13 which is received in a counterbored portion 10B of the bore 10A in the neck portion 12. The collar 13 is permanently fixed in the club head 10, eg by adhesive. The collar 13 has on its inner surface 13A axiallly extending surface discontinuities, eg splines. A portion 16C of the bush 16 is provided on its outer surface with surface discontinuities, eg splines, which extend axially with respect to the axis of the outer surface 16B of the bush. The surface discontinuities of the collar 13 and bush 16 are engagable with each other when the bush is inserted into the bore 10A in the club head 10 and these serve to hold the bush, and hence the shaft, in rotational position relative to the club head.
It will be noted in the drawings that the portion 16C of the bush 16 is of a slightly larger outer diameter than the remainder of the bush and this means that the bush can be inserted into the bore 10A in the club head 10 an initial distance and not be prevented from rotating. Once the desired rotational position of the bush 16 has been ascertained, it can then be fully inserted so that the collar 13 and bush 16 engage with each other. This position is seen in Figure 2.
Here, a notch 11 is provided on the bush to indicate a datum point, eg at the rotational position in which the lie of the club will be most "upright", and a label is put on the shaft 14 after fixing the bush 16, with graduated markings to indicate lies of the club between "upright" and "flat" and "open" and "closed". It will be appreciated that other configurations of collar and bush are possible instead of round cross-sections with a splined engagement, for example, where the collar and bush have polygonal cross-sections. Also, it is possible to provide other ways of providing an "offset" for the shaft.
For retaining the bush 16, and hence the shaft assembly, in the club head assembly, a wedging means in accordance with the invention is provided, which here is in the form of a screw-threaded fastener 20. A hole 20 is drilled into the club head 10 for inserting the fastener 20. The hole 21 is drilled through the sole IOC of the club head 10 so as to break into the bore 10A and the axis of the hole 21 intersects the axis of the bore 10A. This allows the fastener 20 to engage the outer surface 16B of the bush 16 when the shaft assembly is in position in the bore 10A of the club head assembly, with the threads of the fastener bitingly engaging the outer surface of the bush. Here, the fastener 20 is a parallel screw, and the axis of the hole 21 is set at a slight angle to the axis of the bore 10A in the club head 10, this angle being represented in Figure 2 by angle b. This arrangement means that the fastener 20 serves to wedge the bush 16 into engagement with the bore 10A of the club head as it is screwed in. Also, the biting engagement of the threads of the fastener with the outer surface of.the bush gets progressively deeper the further the fastener is inserted. The angle b is relatively small, eg 4.5°, so that the fastener 20 engages the outer surface of the bush 16 over a sufficient distance to achieve a satisfactory purchase or grip. The lower portion of the outer surface of the bush 16 preferably has surface irregularities, eg splines, and this enhances the biting engagement of the threads of the fastener as they cut into the outer surface of the bush.
It will be noted that the inclined arrangement of the fastener means that it is able to act rather like a barb and prevent withdrawal of the bush from the club head even if the connection between the bush and the club head should work loose.
In practice, a chosen club head assembly can be combined with a chosen shaft assembly in a chosen relative rotational position and the assembled club temporarily secured using the fastener 20. The club is now in a condition in which it can be tried out in practice, ie used to hit golf balls. If adjustments need to be made, the club can be quickly and easily disassembled (simply by removing the fastener) and a new combination put together. The thus adjusted club can be temporarily re-fastened using the fastener and tested again. In this way, each individual has the opportunity to find by trial and error the club which suits him best. When the final choice has been made, the club can then be finished by fixing the shaft assembly permanently to the club head assembly. This is done by means of adhesive which is applied. between the outer surface of the bush and the bore .in the club head. The fastener is not used in the finished club. To make the club legal under the rules of golf, however, a pin 18 is inserted through a hole 19 in the club head 10 to engage a groove 17 in the bush 16. The fastener 20 preferably has approximately the same weight as the amount of adhesive in the club head in the finished club because this means there will be no detectable difference in the "swing weight" of the club between its temporarily assembled state (when it was tested) and its finished state.
It will be appreciated that a shaft assembly without an "offset" bush may be used, or the shaft assembly may have a plain bush with no offset or no bush at all and the club head assembly need not necessarily comprise a collar.
The club shown in the drawings is a "wood", but it will be appreciated that the invention may equally be for clubs which are "irons" or putters.
