| PROBLEM TO BE SOLVED: To improve characteristics in use and to enable a more exact shot by forming the lower part inclusive of a front end part where a club head is received in such a manner that this part occupies the specific length of a shaft and is formed to a shape higher in hardness than the upper part. SOLUTION: The upper part inclusive of a grip 16 is so formed as to exhibit the predetermined hardness. The lower part 20 including the front end part 18 to receive the club head 14 and having a bump part 22 has the shape to occupy the lower one-third the shaft 12 and to have the hardness higher than the predetermined hardness of the upper part 24. The lower part 20 and the bump part 22 enhance the hardness of the lower part of the shaft 12, lessen the tendency of the shaft to twisting, enhance the control of the club head 14 and consequently provide the higher exactness to the shot. Further, the bump part 22 has a reverse tapered part or migrating part of a detecting diameter and, therefore, the diameter and taper of the upper part 24 may be made nearly similar to those of the ordinary shafts.

| PURPOSE: To increase the kinematic energy to be obtained when a shaft is swung, by arranging members which are multiply connected to a hollow structure of the shaft to each other, and extending the substantial length of the shaft. CONSTITUTION: A central bar 6 is inserted in a hollow part of a shaft segment 1, and an insertion side end part of the central member 6 is connected to the shaft segment 1 through an intermediate tube 4. Buffer spaces 10, 11 to partially allow the relative deviation in the direction orthogonal to the axial direction of the central member and to the axial direction of the shaft segment 1 as the shaft 2 is deformed, are provided around the central member 6. When the blow is applied to a head of a club, the angle of inclination of the shaft 2 at a part 3* is suddenly increased compared with the inclination at an opening part 3, the head is bent rearward, the energy of deformation to be accumulated in the shaft 2 is increased, and the maximum speed of the head is increased. | ||||||

| PURPOSE: To achieve reinforcing a shaft tip by increasing wall thickness(WT) by rotary-swaging-machine the one end of the shaft, buy mandrel-drawing- machining the rear of the shaft, then, by rotary-swaging-machining the front, middle and rear of the shaft. CONSTITUTION: The one end of a hollow metal shaft 10 with an outside diameter(OD) 21 and a wall thickness(WT) 20, is rotary-swaging-machined to have the front 62, rear 60 and middle 61 connecting between the front and rear of the shaft, and an OD 29 at the front 62 of the shaft in a smaller size than the OD 21 and a WT 22 in a thicker size than the WT 20. The rear 60 is then drawing-machined to shape the shaft having an OD 26 in a smaller size than the OD 21 and in a larger size than the OD 29. Further, the shaft including the front 62, middle 61 and its neighborhood rear segment is rotary-swaging- machined and shaped so that the front 62 has an OD 99 in a smaller size than the OD 29 and a WT 94 in a larger size than the WT 22, and than the middle part is smoothly changed from a narrower tapered shape 98 from the OD 26.

| PURPOSE: To form a shaft with proper thickness by applying a rotary swathing process at the end of the shaft, sink drawing process to form steps on the outer surface of the shaft, and rotary swathing process at the outer surface with steps. CONSTITUTION: A rotary swathing process is applied to one end part 12 of this metallic shaft 10 to reduce the outer diameter of the part and to thicken the wall 22 of the part. A second shaft part 25 adjacent to the end part 12 is processed by sink drawing by way of a series of four drawing holes whose diameters are reduced to form a series of step group 26-30 so that the outer diameters become larger as parting from the shaft end part 12. After that, the second shaft part 25 with steps on the surface is given a rotary swathing process to be tapered smoothly without steps, whose diameters gradually reducing toward the shaft end part 12. As a result, the shaft part 25 is made to be the tip part reinforced by thickening the wall whose thickness is even all over the tapered shaft part. COPYRIGHT: (C)1990,JPO | ||||||
