Abstract

A golf club shaft has a head end consisting of a cylinder of substantially constant wall thickness. This end of the shaft is to be connected to the socket of a conventional golf club head and in order to match the shaft with a selected golf club head a portion of the cylinder is severed. The shaft is thus matched in length and flexibility characteristics to the selected golf club head. A matched set of shafts may be provided by selecting a plurality of initially identical shafts and severing selected amounts from the shafts.

Hitherto in the manufacture of golf clubs it has been found necessary to manufacture for each club head a range of shafts of differing'flexibilities, resilience or whip, the shafts for any one club head being of one length and tapered from one end to the other. These shafts are individually cold-drawn through a series of dies arranged in spaced-apart relationship, each die being variable in size so that the resultant shaft consists of a plurality of hollow tapered sections of circular cross-section.
Since the known shaft is tapered along its length one end is thick-walled and small in diameter whereas the other end is relatively thin-walled and large in diameter and the contribution of each shaft section to the flexi-- bility of the shaft varies inversely with the diameterof the section. Thus, the section of smallest diameter, which is the section fitted to the club head, contributes the greatest proportion of the shafts flexibility, and is usually referred to as the whip zone of the shaft.
Each shaft manufactured in the range for any one club head has the whip zone so proportioned during manufacturing as to impart a particular characteristic to the shaft. It is, therefore, usual for any adjustment to the length of the shaft to be made at the end of the shaft remote from the whip zone, because if the whip zone were shortened the characteristic of theshaft would be altered, and the diameter of the end of the shaft would be increased which could lead to difficulty in fitting the shaft to the socket of the club head.
It will be understood that a set of shafts consists of shafts which are matched in flexibility but which are of differing lengths so as to be matched to the requirements of club heads having differing amounts of loft carried out during manufacturing of the shaft.
It is a disadvantage of the above shaft that golf club manufacturers require to maintain an extensive stock of each shaft in the range for any specified club head, so that the total stock of shafts required for a range of differing club heads maybe in the range 2 5 million.
It is an object of the present invention to obviate or mitigate the above disadvantages.
According to the present invention there is provided a shaft for a golf club, said shaft having a plurality of hollow sections of which at least one constitutes a hollow whip zone adapted for connection to a golf club head, and wherein said whip zone is in the form of a cylinder.
Further according to the present invention there is provided a method of fitting a shaft to a golf club head including the steps of selecting a shaft according to the last preceding paragraph, shortening the shaft by a selected amount by severing part of said cylinder, mounting the shortened shaft with the whip zone in the socket of the club head, and securing the shaft thereto.
An embodiment of the present invention will now be described, by way of example with reference to the accompanying drawings in which:
FIG. 1 shows a cross-sectional view of part of a shaft for a golf club; and
FIG. 2 shows the shaft fitted to a golf club head.
In the drawings a shaft for a golf club has a plurality of sections 10A, 108 etc., only two of which are an epoxy resin or by-inserting a pin, grub or screw, or-
rivet 14 through the socket 13 and the section 10A diametrically with respect to the shaft 10. The pin may also be used in addition to the adhesive.
To assemble a set of golf clubs wherein the club heads are metallic, say nine in number, and graded in loft according to normal practice, nine identical shafts according to the present invention are selectedand these are shortened by removing a selected amount from the cylindrical whip zone of the shaft in order to produce a set of shafts graded'in length and in flexibility. The respective clubheads and shafts are thereafterfitted and bonded together.
In order to manufacture the shaft according to the present invention a plurality of dies are arranged in spaced-apart relationship, the dies being of different 1 sizes and all but the smallest die being variable in aperture or size. The shaft is cold-drawn through the dies and the die of fixed size produces the whip zone which is of constant diameter and constant wall thickness, in comparison to the sections produced by the other dies, which sections are tapered and of variable wallthickness.
By virtue of the above-described embodiment only one shaft is required for a complete set of golf clubs so that the stock maintained by the club manufacturer may be greatly diminished. Alternatively, the manufacturer may wish to stock two shafts, each according to the present invention, but one shaft being of a suitable length for wooden club heads and the other for metallic club heads. Yet a further alternative would be to have a third shaft according to the present invention but suitable in length only for a putter.
Various modifications may be made, for example the whip zone may include two or more sections which are cylindrical but of differing diameters or the shaft may consist entirely of cylindrical sections of different diameters, or alternatively, the shaft may consist of only two sections, the whip zone which is cylindrical and a single tapered section.
It will be understood that a set of golf clubs may consist of any number of clubs (for example fourteen) and the club heads may be made of any suitable material such as stainless steel, plastics materials, aluminum or wood.
What is claimed is:
1. A method of fitting a golf club shaft to a selected golf club head, including the steps of selecting a shaft having a head end which terminates in a hollow cylinder of substantially constant diameter throughout the length of said cylinder and constant wall thickness throughout the length of said cylinder, matching the shaft in length and flexibility characteristics to the selected golf club head by severing part of the end of said cylinder, mounting in the socket of the club head the end of the shortened shaft from which said part has been severed and securing the shaft thereto to provide a club of desired length and flexibility characteristics.
