When the third joint 3e is rotated in the arrow E direction, the lie angle γ can be increased as shown by the dotted line in FIG. Further, as shown by the solid line in FIG. 4, the lie angle γ is set to a predetermined angle, and in FIG. 1, the third joint 3e is rotated in the arrow F direction with respect to the face progression adjuster 3d. Then, the lie angle γ can be reduced as shown by the chain double-dashed line in FIG.

Next, the face progression d will be described. In FIG. 5, the second joint 3c and / or the third joint 3e are relatively moved to adjust the spacing, and the face progression d The face progression d can be adjusted by adjusting the length of the adjuster 3d itself.

As described above, according to the first embodiment of the present invention, the putter head 1 is rotated about the neck 2 with respect to the first joint 3a to adjust the pull angle α to a desired value. can do. Further, by rotating the first joint 3a with respect to the connecting rod 3b, it is possible to adjust to a desired mounting angle β. Furthermore, the desired lie angle γ can be adjusted by rotating the third joint 3e with respect to the face progression adjuster 3d.

Then, the second joint 3c and / or the third joint 3e are relatively moved to adjust the interval, or the length of the face progression adjustment adjuster 3d itself is adjusted to adjust the face projection. The progression d can be adjusted to the desired length. Therefore, the optimum pull angle α, attachment angle β, lie angle γ, and face progression d suitable for each player can be adjusted at the same time.

Here, the neck 2 and the first joint 3a, the first joint 3a and the connecting rod 3b, the connecting rod 3b and the second joint 3b, the second joint 3b and the face progression adjuster 3d, the face professional. The fixation of the progression adjuster 3d and the third joint 3e, and the third joint 3e and the shaft 4 will be described. The neck 2, the first joint 3a, the connecting rod 3b, the second joint 3c, the face progression, When the adjuster 3d, the third joint 3e, and the shaft 4 are made of metal, a through hole is opened and a knock pin is driven to fix each part, and the first joint 3a, the second joint 3c, the third joint 3e, and the shaft When 4 is made of metal and the connecting rod 3b and the face progression adjuster 3d are made of carbon shafts, each part is fixed with an adhesive. Good to do.

In the first embodiment, the connecting rod 3b and the face progression adjuster 3d are omitted, the second joint 3c is directly connected to the first joint 3a, and the second joint 3c is connected to the second joint 3c. The third joint 3e may be directly connected to. Alternatively, only the connecting rod 3b may be omitted and the second joint 3c may be directly connected to the first joint 3a.

FIG. 6 is a side view showing a golf putter according to a second embodiment of the present invention, and FIG. 7 is an enlarged view of the universal joint as seen from the direction of the arrow in FIG. Will be described with the same reference numerals. In these drawings, reference numeral 11 denotes a universal joint, which is composed of a first connecting arm 12 made of synthetic resin and a second connecting arm 13 made of synthetic resin.

The first connecting arm 12 has the neck 2 connected to one end, and the other end serving as a holding portion 12a that holds the ball portion 13a of the second connecting arm 13 rotatably within a predetermined range. The second connecting arm 13 has a ball portion 13a held at one end by the holding portion 12a, and the shaft 4 is connected at the other end.

Reference numeral 14 denotes a push screw, which is screwed into a screw hole formed in the holding portion 12 and whose tip abuts on the peripheral surface of the ball portion 13a. Reference numeral 15 denotes a knock pin, which locks the displacement of the second connecting arm 13 with respect to the first connecting arm 12.

Next, adjustment of the pull angle α, the attachment angle β, and the lie angle γ will be described. First, the push screw 14 is loosened to make the ball portion 13a rotatable with respect to the holding portion 12a, and then the first connecting arm 12 is adjusted so that the desired pull angle α, attachment angle β and lie angle γ are obtained. Then, the second connecting arm 13 is rotated, and the push screw 14 is tightened to temporarily fix the second connecting arm 13 to the first connecting arm 12. Then, a fitting hole penetrating the holding portion 12a and the ball portion 13a is formed, and a knock pin 15 is driven into the fitting hole to lock the second connecting arm 13 with respect to the first connecting arm 12 to pull the pulling member. The angle α, the attachment angle β, and the lie angle γ can be adjusted as in the first embodiment.

Needless to say, the push screw 14 is removed from the holding portion 12a after the knock pin 15 is driven. Further, if the through hole into which the knock pin 15 is driven is formed so as to pass through the center of the ball portion 13a, it becomes impossible to lock the second connecting arm 13 with respect to the first connecting arm 12 by the knock pin 15, so that the through hole is formed. Must be provided at a position offset from the center of the ball portion 13a.

As described above, also in the second embodiment of the present invention, the optimum pull angle α, attachment angle β and lie angle γ suitable for each player can be adjusted at the same time.

In this second embodiment, a through hole is formed and the universal joint 11 is not locked by a knock pin, and a groove is provided on the inner peripheral surface of the holding portion 12a and a groove is provided on the outer peripheral surface of the ball portion 13a. Alternatively, the adhesive may be injected into both grooves in a state where the second connecting arm 13 is locked to the first connecting arm 12 while being temporarily fixed by the push screw 14.

FIG. 8 is a side view showing a golf putter according to a third embodiment of the present invention. The same parts as those in FIGS. In these drawings, reference numeral 21 denotes a flexible material, which has a neck 2 connected to one end and a shaft 4 connected to the other end, is three-dimensionally bendable, and has an appropriate hardness. , A lead pipe, etc.

Next, adjustment of the pull angle α, the attachment angle β, and the lie angle γ will be described. First, with the neck 2 and the shaft 4 attached to the flexible material 21, both ends of the flexible material 21 are held and fixed by a predetermined jig. Then, by applying a predetermined force to both jigs to bend the flexible member 21 so that the desired pull angle α, attachment angle β and lie angle γ are obtained, the pull angle α, attachment angle β and line angle γ can be adjusted as in the first and second embodiments.

As described above, also in the third embodiment of the present invention, the optimum pull angle α, attachment angle β and lie angle γ suitable for each player can be adjusted at the same time.
