Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved golf putter.

[0002]

[Prior Art]

 A golf putter visually measures the undulations, turf, distance, etc. on the green, and gives comprehensive information on the power and direction of the hit ball, which requires extremely delicate sensation. For this reason, the head has a unique shape and various materials, but any of them can be restored while the ball surface is slightly deformed on the striking surface and moved while rolling on the green. There is.

[0003]

[Problems to be solved by the device]

 Ordinary golfers such as office workers have few opportunities to actually go to the actual course, and even if they practice on the practice field, they are mainly hit with a large distance such as a driver or an iron. Therefore, the practice of the approach is less than these, and even less, and if you are putter, you will go to the course with almost no practice on the green. As is usual with Sunday golfers, the number of hits increases as the green approaches, and the number of putters hitting the green often corresponds to the number of hits hit before.

[0006] Thus, although the putter's success or failure has a great influence on the golf score, in reality, the practice is only practiced on the practice green shortly before the course. According to the results of studies by the present inventors, since the striking surface of the putter is a hard one, which is mainly made of metal, the surface of the ball is slightly deformed at the time of hitting, and this is due to the reaction force when restoring. The ball is often given rotation. Therefore, the golfer has to instantly and intuitively grasp various conditions such as the striking force, the striking direction, and the striking speed, and it is difficult for a general golfer to know this in a short time. It was The present invention solves the above-mentioned drawbacks of conventional putters, and an object of the present invention is to provide a putter having excellent striking force adjustment and ball directionality.

[0005]

[Means for Solving the Problems]

 The putter according to the present invention for achieving the above-mentioned object has a cavity formed inside the putter body, is formed so that the striking face side is thin and can be deformed, and the cavity is filled with a pressurized gas. It is characterized by. The reason for making the striking surface thin is that the gas hitting the inside of the cavity is pressed from the back side by the pressurized gas to impart a gas spring action to the striking surface. Therefore, although this striking surface is subtle when striking the ball, it deforms into a concave shape and makes wide contact with the rear part of the ball, and when this striking surface restores, the pressure of the pressurized gas and the repulsive force of the striking surface. It is for giving the ball a turning force.

Various metal plates are used as the material of the striking surface, and for example, a stainless plate of 0.8 to 1.5 mm can be used. If the regulations allow, it is also possible to use a synthetic resin molded product reinforced with a reinforcing fiber or a ceramic plate. The striking surface is made of a thin metal plate that expands slightly forward when the back pressure of pressurized gas is applied, covering the front surface of the concave cavity formed in the center of the putter body and brazing. It is integrated with the putter body by the joining means.

A check valve is provided in the putter body to fill the cavity formed in the putter body with the pressurized gas, and the pressurized gas is injected from the check valve. If the pressure is insufficient, the check valve is used. Pressurized gas can be injected through the valve. Pressurized gas should be selected so that the pressure does not change significantly within the ambient temperature range. As this gas, butane gas, sulfur hexafluoride and the like are suitable, but other gas may be used. The pressure for filling the hollow portion may be about 1 to 30 atm, preferably about 15 atm.

[0008]

[Work]

 The striking surface of the putter body is made thin and deformable, and a cavity is formed behind it, and pressurized gas is filled in this cavity, so the striking surface is slightly rearward when hitting a ball. When the deformation occurs and the deformation is restored, the back of the ball is pressed to promote the rotation of the ball, so that a putt having excellent directionality and adjustability can be performed. Furthermore, since the number of surfaces that come into contact with the ball increases, it is possible to prevent side spin from occurring during putting.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing the main body 1 of the golf putter P in a sectional view. A hollow portion 2 is formed in the center of the main body 1 along the longitudinal direction, and a check valve 3 is provided below the hollow portion 2. Is provided. A shaft 4 is attached above the main body 1.

FIG. 2 is a cross-sectional view of the central portion of the putter body 1, and the striking surface 5 that closes the front surface of the hollow portion 2 is formed of a thin metal plate. This thin metal plate is made of a stainless steel plate with a thickness of about 1 mm, and this is pressed to form an edge 6, and the edge 6 is fitted into the opening surface of the cavity 2 and then It is hermetically joined by a joining means 7 such as attachment. The cavity 2 of the putter body 1 having the above-described structure was filled with butane gas of 4 gas pressure.

In FIG. 3, a rib 5a is formed on the back surface of the center of the striking surface 5, and the back surface of a predetermined portion is strengthened in a predetermined direction to enhance elasticity. A subtle change can be given to the rotation of the ball hit by the size of the rib 5a and the mounting part and direction. FIG. 4 shows a structure in which the striking face 5 is prevented from being largely deformed forward when the cavity 2 is filled with a pressurized gas, and a reinforcement made of a metal wire behind the center part of the striking face 5. A member 8 is provided.

According to this structure, even if the cavity 2 is filled with high-pressure gas, the striking surface 5 is prevented from being deformed forward by the reinforcing member 8, so that the striking surface 5 is prevented. When the ball is hit with a thin wall, it can be greatly deformed along the ball to make the direction of the hit ball accurate. FIG. 5 shows that the striking face 5b is formed in the same body as the putter body 1. The deformation amount of this striking face 5b is inferior to that of the other embodiments, but the thickness of the striking face 5b is adjusted. By doing so, sufficient directionality can be given to the ball hit.

[0013]

[Effect of the device]

 As described above in detail, in the putter according to the present invention, the cavity is formed inside the putter body, and the striking surface side is made thin so that it can be deformed. It is configured. Therefore, according to the putter of the present invention, when the ball is hit, the hitting surface is deformed to widely contact with the back of the ball and the sweet area is extremely expanded. Then, the ball rolls forward due to the repulsive force of the striking surface and the ball, so that the ball can be rotated in the correct direction. Therefore, even golfers unfamiliar with golf can perform excellent patting.
