Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf putter used to hit a ball into a hole on a green in a golf game.

[0002]

2. Description of the Related Art Half of the score (par) in a golf competition is devoted to putting. The putter is equal in weight to all other clubs on the score. It is often said that putting is more of a mental side than a technical side, and a putter that gives a sense of security and confidence to play with a normal mind is desired.

[0003] During a golf competition, the distance the ball travels on the fairway and the accuracy of the ball relative to the target leads to a good score for the competitor and how much less putts on the green. Is a good score.

[0004] Even if you make a great shot on the fairway, you will not be able to put the ball a short distance on the green in the cup, and if you remove it many times, the score will not be consistent, leading to scoring of the score and ultimately a bad score Must be content with.

[0005] As described above, the number of putts on the green has a greater weight as it affects the score, and each golfer has been accumulating serious training and concentrating his brain on this practice. is there.

[0006]

In a conventional putter, when a ball is hit with a putter on a green, it does not easily roll straight.

Further, at present, when the head comes into contact with the ball, there is no head having cushioning properties, and the head is almost like a rigid body at present.

Further, since the mounting angle of the head to the shaft cannot be adjusted according to the lie of the ball with the lie of the ball, it is difficult for the central portion of the head to hit the ball.

In addition, the current putter has almost the same weight of the shaft and the head and has a relatively high center of gravity, so that it is difficult to perform a stable putter stroke.

[0010]

SUMMARY OF THE INVENTION The point of the present invention is to satisfy the restrictions on putter design in golf games and the conditions permitted for putters. The head, neck, shaft, and grip characteristics were used as a single putter for a well-balanced design. The balance means that the weight of the head is directly felt by the grip by setting the neck, shaft, and grip to 1 with respect to the head weight of 5. Therefore, it is easy to apply strong and weak touches, and it is possible to gently perform a hitting method with slow motion that is important for putting, thereby increasing the sense of parallelism and sense of distance.

The material of the head is formed of refractory clay,
By firing at 0 ° C., we have developed a hard and soft characteristic that cannot be made into hard wood such as metals such as iron, copper, and stainless steel, various natural stones, artificial stones, and persimmon. By controlling bubbles generated during firing, the surface was hard and the inside was focused on the characteristics of soft ceramics. Furthermore, by baking coating, the strength to withstand putting was given.

The head has a simple L-shaped cross section. The long side of the head is 100 mm, the short side is 50 mm,
The thickness is 10 mm, and each side is chamfered at 45 degrees. The chamfer beneath the face is particularly important, and in the basics of play it is usual to hit the putter head slightly off the grass. Because the head is eaten by the turf, the putter of the present invention can catch the ball in a plane always parallel to the turf surface by the angle.

The standard size of the ball is 42.67 mm in diameter.
As described above, the weight is clearly 46 g or less. Although the spot of the ball is about 21.4 mm, the center of the neck of the shaft extension line is set to 15 mm from above so that the sweet spot of the head of the present invention can be hit like a billiard ball (hit slightly above the contradiction point). You have set. This makes it possible to hit a ball with a ball speed with no spin against a distant target.

The reason for setting the head weight to 250 g is as follows.
By being suitable for hitting a ball of 46 g (about 1/5 of the head weight) and setting the shaft weight to 50 g, the touch is transmitted to the hand at the moment of hitting. Therefore, 5
The ratio of (head): 1 (neck + shaft): 1 (ball) is a point different from the conventional putter design.

A further feature of the present invention is that the sound when the ball is captured at the sweet spot and the sound when the ball deviates on both sides are clearly different.

According to the official competition rules, the shaft angle is 10 degrees or more. Directional lines may be added to the upper surface of a conventional putter. It is only the center of the head, and depending on the height, if the shaft angle is 15 degrees, the illusion of the eye can occur unless the direction line is higher. Therefore, in the present invention, the illusion is used by setting the direction line of the ball width slightly above the center. This ceramic head satisfies the vision (direction), hearing (strength), and touch (touch) among the five senses of human beings.

The neck (joint between the head and the shaft) was made of a reinforced resin plate and a pipe of the same material, and was set so that touches important for cushioning and putting between the head and the shaft could be controlled.

The driver and the shaft of the iron are designed to fly far away. That is, it utilizes the shaft's scissors, stiffness and twist. In short, it is the principle of whip. However, the shaft in the putter is taboo that is too thin or twisty, but with the neck of the present invention, a small scenery is created near the sweet spot so that the ball can be hit more accurately. . The official position of the neck is allowed to be at the center of the head, but the angle to the top of the grip on the extension of the shaft is specified to be 10 degrees or more. Therefore, the present invention has the following features to solve the problem.

The connecting contact portion between the head and the neck is made movable by a hinge pin having a thread at its tip. It can be fixed by screwing with a hinge pin, but by attaching four ratchet holes, there is no hole at the center (angle 0 position), and by attaching ratchet holes at the left and right positions of 10 degrees and 20 degrees, the address angle It was designed to be adjustable. Further, the scenery angle of the neck is 3 degrees or less to the left and right, which is a very small amount much less than 20 degrees or less. The result is a putter that can be used for both right and left hits (shaft and grip are circular in cross section). The shaft is a hollow shaft with a butt portion used for a fishing rod made of a carbon material and a grip integrated type (weight is 50 g). As a result, touch and sound are transmitted to the grip, making it easier to grasp the strength of putting. The shaft has a total length of 80 including the neck.
0 mm (specified 457 mm or more). The grip was 300 mm except for the taper.

Therefore, in the present invention, the head is made of a ceramic material in order to give the putter a cushioning property.

Further, in the present invention, in order to give the putter a cushioning property, the shaft and the head are connected via a neck made of a flexible member.

Further, the present invention relates to a golf putter in which a neck and a head provided at a lower end of a shaft are pin-connected via a hinge pin so that the ball can be hit with the lie of the ball. To the target direction of the hit ball, the shaft can swing in the direction orthogonal to the target direction of the hit ball, and the tilt angle is determined by the ratchet mechanism that provides the shaft and head to the head and neck at the required tilt angle of the shaft A golf putter was screwed with a connecting pin.

Still further, the present invention provides a golf putter having a neck interposed between a shaft and a head so that the center of gravity of the putter is positioned as low as possible and a stable stroke can be obtained. This is a golf putter in which the weight of the head is set to 4 to 6 times the weight of the putter and the neck.

The present invention relates to a golf putter comprising a shaft, a head, and a neck interposed therebetween, as a specific example of a preferable putter. And the hinge pin is directed to the target direction of the hit ball so that the shaft can swing in a direction orthogonal to the target direction of the hit ball of the head, and the shaft and the head can be pivoted at the required inclination angle of the shaft. The angle of inclination was determined by the ratchet mechanism provided above, and the head was set to 4 to 6 times the weight of the shaft and neck by screwing with the connecting pin.
