Abstract

(57) [Summary] [Purpose] To obtain a putter club capable of accurately rolling the ball in the target direction even when the sweet spot on the face surface of the head is removed and the ball is hit. [Structure] A head 1 and a shaft 4 extending obliquely upward from a toe 5 of the head over the heel 6 are provided,
When the shaft 4 is supported at the center of gravity G of the club, the head 1
Hangs down with the heel 6 down, and the hitting face face 1'is almost perpendicular to the ground.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a golf putter club for putting on the green.

[0002]

[Prior art]

 Conventional putter clubs are available in L and T shapes. In the case of the L shape, the shaft stands from the heel of the head, and in the case of the T shape, the shaft stands from the middle of the head near the heel.

[0003]

[Problems to be solved by the device]

In the conventional putter club, as shown in FIGS. 6 and 7, when the head is solened, the intersection P ₁ of the mood perpendicular line V ₁ from the upper end of the grip 3 with the ground, the shaft 4 and the head. The sweet spot 2 of the head is located outside the line L connecting the above P ₁ and P ₂ at the intersection P ₂ with the ground of the recollection perpendicular line V ₂ from the connecting point. Therefore, when the ball is hit with the sweet spot 2 of the head removed, a twisting force (arrow in Fig. 7) that tends to rotate in the palm is generated in the grip so that the hit point deviates from the sweet spot. It is difficult to roll the ball in the direction of the street.

[0004]

[Means for Solving the Problems]

 The present invention was devised to solve the above-mentioned problems of the conventional putter club, and includes a head and a shaft extending obliquely upward from the toe of the head over the upper part of the heel, and the center of gravity of the club is positioned. When the shaft is supported by the head, the head hangs down with the heel down, and the striking face face surface is almost perpendicular to the ground. In this case, the center of gravity of the club is preferably 28 to 30 cm above the ground of the shaft when the head is solened.

[0005]

1 to 5 show an embodiment of a putter club according to the present invention, in which a shaft 4 extends obliquely upward from a toe 5 of a head 1 over a heel 6. The sole 7 of the head is composed of a toe-side ground contact surface 8 and a heel-side slope 9 that intersects this at an angle of about 160 °, and the lower end 4a of the shaft 4 forms a right angle with the heel-side slope 9. ing. The extension 4b above the lower end 4a of the shaft is curved and then extends straight and obliquely upward to form the grip 3. The angle α of the extension 4b with respect to the lower end 4a of the shaft is about 30 °. The head has a symmetrical shape on the toe side and the heel side, and the back side of the face (back face) is a cavity type having a recessed portion 10 sculpted in a similar shape.

The center of gravity G of the club is located at a height H of about 28 to 30 cm from the ground of the shaft 4 when the head is solened (see FIG. 1). The extension 4b becomes horizontal, the head 1 hangs down with the heel 6 down, and the hitting ball face surface 1'is perpendicular to the ground (see FIG. 2).

To perform putting with this putter club, as shown in FIG. 3, the head is soled on the heel-side ground 8, and the grip 3 is used to operate normally. In this case, the shaft 4 crosses the upper surface of the head in the longitudinal direction, but the reference centerline 11 in the ball striking direction, which is displayed on the upper surface of the head, should be viewed without being interrupted by the shaft because it is visible to both eyes. You can Although there is a longitudinal groove on the upper surface of the head, this groove may be eliminated and the upper surface of the head may be flattened.

[0008]

[Effect of device]

When the putting is performed as described above, as shown in FIG. 1, a point P _{1 at} which the recollection perpendicular line V ₁ from the upper end of the grip intersects with the ground, and a recollection perpendicular line V ₂ from the connecting point between the shaft 4 and the head are grounded. the two points of intersection between P ₂ is the head of the ball striking off Esu surface 1 'some of the line L connecting the. Therefore, the twisting force, which is generated when the ball is hit while removing the sweet spot 2 on the face of the hit ball, tends to rotate in the palm, is extremely small. When the shaft is supported at the center of gravity G of the club, the head hangs down with the heel 6 down, and the hitting face surface is almost perpendicular to the ground. Cancels the above twisting force. For this reason, you can hit the toe side and heel side of the head with both hands and hit the ball with the same principle as if you press anywhere on the face surface without blurring, and the entire face surface of the head is aimed as a sweet area. You can roll the ball to. In addition, the direction of the hit ball face surface at the moment of impact can always be squared with respect to the target line and shaken.

[0012] Furthermore, since the heel of the head comes close to the body when it is set up for putting, a sense of security is created, and furthermore, it is possible to accurately address and swing smoothly.
