| PROBLEM TO BE SOLVED: To satisfy both weight reduction and a performance aspect such as rhythm and a kick point by applying a PCCP structure to a shaft. SOLUTION: A PCCP structure 2 is applied to the total length of a steel shaft 11 having steps 3. In this PCCP structure, a macroscopic shape is close to a cylindrical shape, and a pair of triangles are juxtaposed in a diamond shape or a pair of trapezoids are juxtaposed in a hexagonal shape to form a pseudo-cylindrical recessed polyhedron. This shaft is different in an outside diameter of a cylindrical shape between the grip side and the head side, and normally, the outside diameter is gradually changed by the repetition of a small step difference such as the steps 3 of about 20 pieces. For example, the PCCP structure 2 is formed by using an isosceles triangle as a component, any steps 3 are arranged so as to become the (n) pieces in the outer peripheral direction, and the PCCP structure 2 is applied over the total length. Then, the isosceles triangle becomes small as it proceeds to the head side, so that the whole shaft can be uniformized. | ||||||

| PROBLEM TO BE SOLVED: To inexpensively and easily produce a shaft which has moderately high rigidity and is good in operability. SOLUTION: This shaft is formed with an tapered part 16 diametrally expanding toward a grip end 14. The taper gradient of this tapered part is 15/1,000 to 35/1,000 and the length thereof is 200 to 350 mm. The outside diameter of the grip end is 18 to 25 mm. A semi-tapered part 19 of 4/1,000 to 13/1,000 in taper gradient is formed on a front end 18 side nearer the tapered part. A hick point exists at a position of 40 to 46% from the small diameter end with respect to a shaft length. As a result, the number of necessary parts is small and production is easy, nevertheless, the lightweightness, the moderate hardness and the high rigidity of a hand side as well as excellent strength balance and a good impress at the time of hitting are obtd.

| PURPOSE: To damp the vibration of a golf club by connecting a rigid tubular sleeve provided on a shaft coaxially to the shaft by a viscoelastic material of a predetermined thickness, which is stressed by the sleeve. CONSTITUTION: A damping assembly 10 having a rigid tubular sleeve 11 made of an aluminum-chromium-zinc alloy is arranged on a portion 15 of a shaft 1 at a predetermined location in correspondence with the vibration wave loop. The wave loop on the golf club shaft 1 is located in the vicinity of 1/3 of the shaft 1 as viewed from a head 3. The portion 15 of the round shaft 1 of the rigid tubular sleeve 11 is connected to a second sleeve 12 which is coaxial with both the shaft 1 and the rigid sleeve 11. The second sleeve 12 is pre-coated with an adhesive layer to promote the mechanical completion between the rigid stressing sleeve 11 and the shaft 1. The viscoelastic intermediate combining layer 12 has a damping coefficient tan delta between 0.4 and 1.2 at 25 degrees centigrade. | ||||||

| PURPOSE: To simply move the centroid position of a shaft to the large diameter side, and to increase the weight of the golf club head by the same swing balance by inserting and fixing a centroid adjustment metallic pipe whose length size is within a specific range, from the large diameter end of a metallic shaft main body 1. CONSTITUTION: The golf club shaft is constituted of a metallic shaft main body 1, and a metallic pipe 3 inserted and fixed from its large diameter end 2, and as for the metallic shaft main body 1, a pipe made of chrome molybdenum steel of equal wall thickness is stepped to plural stages by cold drawing. Also, the metallic pipe 3 is used for adjusting the centroid, its length size A is set to 50mm-350mm, and also, its weight is set to 10g-50g. As for the pipe 3 inserted from the large diameter end 2, it is desirable to fix it with an adhesive agent, but it is also possible to fix it by caulking and press fitting, etc. Also, when the over-all length of the shaft main body 1 and a distance from the thin diameter end 4 to the centroid G are denoted as L and B, respectively, and also, the centroid position is shown by (B÷L)×100(%), 56≤(B÷L)×100≤65 is desirable.

| PURPOSE: To vary the kick point of a wood golf club shaft without changing the static flexing characteristic of the shaft by specifying the overall length from a butt end to a chip end, the outside diameter of a butt section, the outside diameter of a chip section, and the gradient of a taper section in the direction of the chip section. CONSTITUTION: A shaft 10 is about 44 to 45 in. in overall length from a butt end 2O to a chip end 28 and includes a butt section L 2, a chip section L 3, and a middle taper section L 1 interconnecting the sections. The butt section L 2 is about 1.524cm (0.6in.) in outside diameter, and a chip is about 0.0889cm (0.035in.) in outside diameter. The taper section L 1 slopes toward the chip section L 3 at a gradient of about 0.018 to 0.025cm/cm (in./in.). The taper section L 1 is shorter than the butt section L 2 and longer than the chip section L 3 but not longer than about 35.56cm (14in.). A shaft kick point is located at a distance of at least about 73.66cm (29in.) from the butt end 20. COPYRIGHT: (C)1991,JPO | ||||||

| A set of golf club shafts for a set of golf clubs is made so that the natural frequencies of vibration of the shaft for the various clubs are matched. Each of the shafts includes a butt portion, a tip portion, and a plurality of stepped portions between the butt portion and the tip portion. The length of the butt portion, the length of the tip portion, and the length of all of the stepped portions except one is the same for all of the shafts. The length of said one stepped portion of each shaft is selected to provide the shaft with the desired natural frequency of vibration, and the difference in the overall length of two shafts corresponds to the difference in the lengths of said one stepped portion of the two shafts. The torsional resistance of each shaft is increased without increasing the weight of the shaft by providing a shaft with relatively large inside and outside diameters and a relatively small thickness. | ||||||

| A light weight golf club shaft and a method of making it out of metal tubing are described. The metal must have, after heat treatment, a yield strength equal to or greater than 220,000 lbs./in.2 to avoid permanent shaft deflection in use. The metal must also have an ultimate strength equal to or greater than 240,000 lbs./in.2 to avoid shaft breakage in use. The finished shaft must attain the impact and permanent set results set forth in the specification. To fabricate the shaft in a variety of lengths and flex patterns needed to accommodate a golfer's individual needs, a collection of manufacturing specifications incorporating relationships between the working material, the initial size of the work piece, and the final shaft product length, taper, weight, and flex are presented. A test is defined for measuring the final shaft product's flex pattern. | ||||||

| An improved golf club shaft and golf club, the shaft being of stepped configuration, having a uniform outer diameter butt end portion having a uniform wall thickness at least 10 inches (254mm) long, the uniform wall thickness being not greater than 0.012 (0.305mm) and a plurality of cylindrical step portions of progressively smaller outer diameter terminating in a tapered tip end portion having a wall thickness at the tip end of at least 0.024 (0.610)mm). The shaft is characterized by a redistribution of metal which results in a balance point closer toward the tip of the shaft, making it possible to use a lighter head without affecting the swing weight. | ||||||

| The body member (250) comprises two inserts (202 and 208) positioned therein. A load member (206) extends between (202 and 208). A load adjuster (203) produces a tension force in the load member (206) and an opposite compression force on body member (250). Changes in the bending stiffness and vibrational bending frequency of the body member (250), for example when used in a golf club shaft, is proportional to the axial force applied to it. | ||||||
