Abstract

PROBLEM TO BE SOLVED: To provide a putter for golf which enables an approach a proper angle of a face by turning a putter head through a thread of a screw centering around it on the axis thereof parallel with the surface of a face thereof to set the angle according to the judgment of the condition of lie anywhere on the green. SOLUTION: The head 4 of the putter is screwed down with a screw 5 at a lower end part of a shaft 2 of the putter 1 for golf on the axis X thereof parallel with the surface 6 of the face thereof and is tuned through the thread thereof centering around the screw 5 by loosening the screw 5 thereby adjusting the angle of the face surface 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a putter head structure for a golf putter.

[0002]

2. Description of the Related Art A putter for golf is a club used for hitting a golf ball and putting it in a cup on a green of a golf course, and a putter head is fixed to a lower end of a shaft at a fixed angle. . On the other hand, a club called a pitching edge or a jigger is used as an approaching club from around the green, but a putter is used around the green depending on a distance from a lay or a cup. .

[0003]

However, since the putter head is fixed at an angle close to a right angle suitable for rolling the ball, the putter head is useful in a lie around a green where the ball can be hit with a feeling of putting. However, in a lie where there is a slope or bump around the green, the face of the putter head is likely to open,
The angle of the ball is controlled by opening the ball.

[0004]

According to the present invention, a putter head is screwed onto a lower end portion of a shaft of the golf putter by a screw on an axis parallel to a face surface.
By loosening the screw, the putter head is rotated around the screw to adjust the angle of the face surface. Therefore, by turning the putter head around the screw according to the judgment of the lie situation around the green,
Can be set to an appropriate angle.

[0005] Further, since a screw is used and a mounting structure is used which is screwed on the axis, the putter head can be properly rotated according to the screw thread without tilting, and the screw is slightly loosened. Only with this, an appropriate and sufficient amount of angle adjustment of the putter head can be performed, and the adjustment and re-fastening can be quickly performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A golf putter 1 has a grip 3 at an upper end of a shaft 2 and a putter head 4 at a lower end.

A putter head 4 is screwed onto a lower end portion of the shaft 2 of the golf putter 1 with a screw 5 on an axis X parallel to the face surface 6.

The putter head 4 has its base end face aligned with the axis X.
A flat seat surface 8 is formed on a plane orthogonal to the above, and a female screw hole 7 for screwing the screw 5 is provided in the head 4, the female screw hole 7 is extended on the axis X, and Flat seat surface 8
And let it open.

On the other hand, the lower end of the shaft 2 has the axis X
Is formed at right angles to the flat bearing surface 10. As a specific example, a rectangular flat seat plate 9 is integrally provided at the lower end of the shaft 2, and one and the other surface of the flat seat plate 9 are formed as planes parallel to each other and orthogonal to the axis X, and the flat seat surfaces 10 and 11 are formed. To form

As means for attaching the flat seat plate 9 to the lower end of the shaft 2, a connecting part in which a female screw cylinder 19 is connected to the upper end of the flat seat plate 9 is formed. The female screw cylinder 19 has a female screw hole 2 extending at right angles to the axis X and opening at the upper end surface thereof.
0, and the other end of the shaft 2 is provided with a screw 21 protruding from the lower end face thereof, and the screw 21 is screwed into the female screw hole 20 to screw the above-mentioned connecting component, that is, the flat seat plate 9 to the lower end of the shaft 2. I do.

At the center of the flat seats 10 and 11, that is, in the center of the flat seat plate 9, a mounting hole 12 (with a female screw thread) centered on the axis X and opened at the flat seats 10 and 11 is formed. No sliding holes).

As shown in FIGS. 1 to 6, a flat seat surface 8 at the base end face of the putter head 4 is in parallel with one flat seat surface 10 of a flat seat plate 9 screwed to the lower end of the shaft 2. The female screw hole 7 and the mounting hole 12 are concentrically communicated on the axis X in contact with each other, and the screw 5 is inserted into the mounting hole 12 from the other flat seating surface 11 side of the rear flat seating plate 9. The screw 5 is screwed into the female screw hole 7, and the flat seat surface 14 of the head 13 of the screw 5, that is, the flat seat surface 14 orthogonal to the axis X
Then, the putter head 4 is screwed to the lower end of the shaft 2.

The flat seating surface 11 is a seating surface on which the player stands, and the screw 5 is screwed in from the seating surface on which the player stands.

As another example, as shown in FIGS. 7 and 8, a screw 22 extending on the axis line X from the flat seating surface 8 of the putter head 4 is integrally formed, and a base end surface of the putter head 4 is provided. The screw 22 is inserted into the mounting hole 12 provided in the flat seat plate 9 while the flat seat surface 8 is in parallel contact with one flat seat surface 10 of the flat seat plate 9 screwed to the lower end of the shaft 2. ,
Then, a nut 23 is screwed into an end of a screw 22 protruding from the other flat seating surface 11 side of the flat seating plate 9 and the nut 23 is attached to the flat seating surface 1.
The putter head 4 is screwed to the lower end of the shaft 2 by fastening until it is fixed to 1.

Accordingly, the putter head 4 is screwed to the lower end of the shaft 2 with the screws 5 and 22 on the axis X parallel to the face surface 6. As an example, the above-mentioned fastening can be ensured by interposing a spring washer 17 between the flat seat surface 14 of the screw head 13 or the flat seat surface of the nut 23 and the flat seat surface 10 of the flat seat plate 9 at the lower end of the shaft.

Thus, by loosening the screw 5 or the nut 23, the putter head 4 is turned around the screws 5, 22 extending on the axis X, that is, the putter head 4 is turned around the axis X. The angle of the face surface 6 is adjusted by screwing.

A seat surface 10 for mounting the putter head 4
The face surface 6 on a circular locus around the screw 5
Is provided on the other side of the putter head 4 and a designated scale 18 is provided on the upper edge of the putter continuous with the flat bearing surface 8 of the putter head 4. The angle of the face surface 6 is recognized based on the coincidence between the angle display scale 15 and the instruction scale 18.

As shown in FIGS. 2, 3 and 8, as an example, when the putter head 4 is in a normal state, that is, in a normal state when the putter head 4 is used on a green, the face surface 6 and the outer side of the flat seat plate 9 are separated. Are aligned on the same plane S, so that the angle of the face surface 6 of the putter head 4 in a normal state can be recognized at a glance, and the operation of returning to the old state after being used in an inclined manner can be performed quickly. .

The head 1 of the screw 5 shown in FIGS. 1 to 6
3 is formed with an engaging groove 16 and an engaging hole, and during play, a coin or a rivet fastener of a golf shoe sole is engaged with the engaging groove 16 or the engaging hole, and the screw 5 is turned to fasten. And relax. Alternatively, since the nut 23 shown in FIGS. 7 and 8 has a square shape, a tool is engaged with the nut 23 and the screw is turned to fasten and loosen.

The putter head 4 and the lower end of the shaft 2 are screwed together on the axis X parallel to the putter face surface 6 by screws 5 and 22.
Is rotated by the guide of the screw thread, and sets the mounting angle (face angle).

[0021]

According to the present invention, an appropriate face angle is set by turning a putter head around a screw on an axis parallel to the putter face surface in accordance with the judgment of the lie situation around the green. And take an approach.

Also, since a screw is used and a mounting structure is adopted which is screwed on the axis, the putter head can be properly rotated according to the screwing thread without tilting, and furthermore, the screwing is slightly reduced. Just by loosening, the putter head can be adjusted to an appropriate angle, and the adjustment and re-fastening can be performed quickly.

Further, according to the putter head screwing structure, the setting of the center of gravity of the putter head can be easily and appropriately designed.
