Abstract

PROBLEM TO BE SOLVED: To prevent duffing and to enable straight swing even at the time of slow swinging by providing a roller having a rotary axis perpendicular to the moving direction of club head caused by the swing so that its lower part can be protruding from the bottom face of a club. SOLUTION: Concerning a golf club 1, a roller 3 having the rotary axis perpendicular to the moving direction of a club head 2 caused by the swing at the time of hitting a ball is provided so that its lower part can protrude from the bottom face of the club. Thus, since power to slide the head 2 to fall in the ground parallelly with the ground is operated, so-called 'duffing' is hardly generated. When the club head 2 is touched with the ground by the straight advancing property of the roller 3, power to rectangularly hit the ball with the club head 2 is operated. Thus, when swinging is performed along the roller 3 even in the case of slow swinging like putter, straight swinging is enabled.

Description

Detailed Description of the Invention

[0001]

[0001] The present invention relates to a golf club.

[0002]

2. Description of the Related Art Golf clubs are tools for hitting golf balls and are classified into three types, namely wood clubs, iron clubs and putters, depending on their use.

This golf club has been variously improved in terms of material, shape, etc., and it is considered that the current golf club is far superior in handling distance and accuracy of the hit ball to those of several decades before and is easy to handle. Has become.

[0004]

However, even with the current golf clubs, golfing is not a game that a beginner can enjoy immediately, but it requires a lot of practice to just fly straight. The most common one is so-called duffing, which hits the front of the ball, causing the club to decelerate due to the resistance of the soil before hitting the ball. Therefore, a situation occurs in which even if the ball hits the ball straight, it hardly flies. Also, due to the resistance of the soil, the swing trajectory of the club itself often changes and the club often does not fly in the desired direction.

Further, it is often the case that the so-called top, that is, the upper part of the ball is hit on the contrary so much that this duffiness is watched for, and this also hardly flies.

To prevent duffing, it is sufficient to prevent the club head from entering the ground. For example, a method of giving a resistance to reduce the head speed will prevent the club head from entering the ground. Even if the number decreases, the flight distance cannot be increased. Therefore, when swinging on the normal ground, it does not become a resistance, and in the case of a swing that seems to hit the front side of the ground,
It would be good if I could prevent duffing, but there is nothing that can produce such a contradictory effect, and I end up having to struggle with duffling and the top.

In order to fly the ball in the intended direction, it is necessary to hit the club head at right angles to the aimed direction. However, this is also difficult for beginners. The angle is inevitable, and it is no longer a right angle. I want to prevent this as much as possible. However, there is no head that moves at a right angle in this way, and it is difficult as described above.

In the end, these things had to be given up as failures due to lack of practice. However, it is a fact that an average office worker who has a short practice time needs a method and a tool for preventing duffing more easily, and a tool for hitting the head at a right angle as much as possible.

[0009]

In view of the above circumstances, the present inventor has completed the golf club of the present invention as a result of diligent research, and is characterized by a swing when hitting a ball. A roller having a rotation axis perpendicular to the moving direction of the golf club is provided so that its lower portion projects from the bottom surface of the club.

The moving direction of the golf club is the trajectory of the club head, and is usually the direction in which the golf ball is about to fly.

The roller is a rotating body which can freely rotate, and may be made of any material such as metal and rubber.
The shape is rod-like or tubular. The number of attachments to one club head is 1 to several, and 1 for long rollers.
One, if it is short, it means a plurality. The roller may be attached to the inside of the club head only so as to be freely rotatable, and does not need to be a special method.

Further, the lower part of the roller must project from the head. This means that, when the head is placed at a normal impact angle, it projects below the bottom of the head. Conversely, there may be a type in which there is no buried portion at all and all the portions project from the bottom of the club head. This type is less effective because the rollers are smaller, but is very simple and inexpensive to manufacture.

In the present invention, as a golf club,
Driver (Wood No. 1) and spoon (Wood 3)
No.) wood club is preferred. This is because the ball is normally hit like hitting the ball so that the club head does not enter the ground. In the case of so-called driving such as an iron club, the roller may become a resistance, which is not preferable in some cases. However, it may be available in long irons.

Further, in the putter, it is advantageous that the straightness of the roller can be utilized to make a hit without accurately swinging or bending in the target direction.

BEST MODE FOR CARRYING OUT THE INVENTION The golf club according to the present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a front view of a head 2 showing an example in which the present invention is applied to a driver 1. The interior is shown by a dotted line. Driver 1
A roller 3 is provided below the head 2 so as to partially project. The roller 3 is rotatably provided on its shaft (using a bearing or the like) and rotates with almost no resistance. FIG. 2 is a bottom view of FIG. It can be seen that it is provided near the front of the head 2. In this example, roller 2
Is a metal cylinder, but other materials may be used as long as it has sufficient strength against impact. When the bottom of the club head hits the ground and the roller 2 starts to rotate, if the surface of the roller 2 and the ground are prevented from slipping, a straightening property is further improved by providing an anti-slip means on the surface of the roller 2 (not shown). No).

FIG. 3 shows an example in which the roller portion does not have any embedded portion at all and protrudes from the bottom portion of the club head 2. In this example, the roller 3 is rotatably mounted on a support 4, which is screwed to the bottom of the head. This example shows that the club of the present invention can be manufactured by modifying the existing club, and is also an example for reducing the manufacturing cost as compared with the examples shown so far.

FIG. 4 shows an example in which the present invention is applied to the putter 5. In this case, the two small rollers 3 are partially projected as in the example shown in FIG.

[0018]

The golf club of the present invention described in detail above has the following great effects. Since the rollers partially or entirely project from the bottom surface,
So-called duffing into the ground is unlikely to occur. Due to the rotation of the roller, a force is exerted that causes the head, which is about to enter the ground, to slide parallel to the ground. This further prevents duffing. When the head contacts the ground due to the straightness of the roller,
A force acts in the direction in which the club head hits the ball at a right angle. Even if you swing slowly like a putter, you can swing straight if you swing along the rollers.
