Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a putter club head.

[Prior art and its problems] Conventionally, a putter club has a structure in which one end of a rod-shaped body having a diameter approximately equal to the diameter of a golf ball is fixed to the back surface of a thin plate-shaped face plate extending between the toe and heel at the approximately central portion. 2. Description of the Related Art A putter club head is known which has a structure in which one end of three golf ball-shaped spheres are arranged in a line and fixed to each other on the rear surface of a substantially central part of a similar face plate.

When this type of putter club head is used, it becomes easier to align the rod-shaped body and the three spheres with the target direction of the ball's roll during address, making it easier to align the direction of the face plate with the target direction of the ball.

However, in this type of putter head, the weight of the head is concentrated in the approximate center between the toe and heel and near the center of gravity of the head, so the moment of inertia around the center of gravity of the head is small, and the weight of the head is concentrated in the center between the toe and heel. As a result, there was a risk that the direction of the face plate of the head would deviate from the target direction of the ball when the ball was hit.

[Means for solving problems]

In view of the above drawbacks, it is an object of the present invention to provide a head of a putter club that allows the face plate to be easily aligned with the target rolling direction of the ball not only during address but also during swing.

According to the present invention, the head body is formed on the rear surface of the substantially central portion of the thin face plate extending between the toe and the heel, and the rear end of the elongated connecting rod extending rearward from the head body has the diameter of the golf ball. A putter club head is provided that includes weight bodies having substantially the same width.

[Effect]

In the putter club head according to the present invention, by aligning the straight line connecting the golf ball and the weight body with the target direction of the ball's roll at the time of address, the orientation of the face plate can be easily adjusted to the target direction of the ball. In addition, in the head according to the present invention, since the weight body is connected to the head body via the long and thin connecting rod, the weight of the head is concentrated on the face plate side and the weight body side, and is concentrated at a location far from the center of gravity of the head. will be concentrated on. Therefore, the moment of inertia around the center of gravity of the head increases, making it easier to maintain the orientation of the face plate set at address during the swing, and making it easier to align the orientation of the face plate with the target direction of the ball's roll when hitting the ball. become able to.

In addition, since the head body and the weight body are connected by a long and thin connecting rod that does not affect the head weight much, by making the connecting rod long, the weight body and the head body can be connected while minimizing the increase in the overall weight of the head. The spacing can be increased. Therefore,
The fan-shaped plane formed by the grip side end of the club shaft, the head body, and the weight body can be made larger, making it easier to keep that plane in the direction of the ball's target during the swing. Easier to keep in direction.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention. Referring to these figures, the putter club head has a thin face plate 11 extending between a toe 11a and a heel 11b, and a head main body 12 is attached to the back surface of the face plate 11 at approximately the center. A hole 12a is formed in the head body 12 for attaching a club shaft 13.

A front end portion of an elongated connecting rod 14 extending in a direction perpendicular to the face plate 11 is attached to the rear portion of the head body 12, and a weight body 15 is attached to the rear end portion of the connecting rod 14. Weight body 15
The rear part of the connecting rod 14 is curved upward so that the connecting rod 14 is located approximately on the swing path line of the face plate 11 and the head body 12.

The weight body 15 is a spherical body having approximately the same diameter as the golf ball 16 (for example, approximately 40 mm). Although not shown, the surface of the weight body 15 is the same as the golf ball 1.
It has substantially the same color and dimple shape as No. 6.

In the putter head having the above configuration, the face plate 11 is made of aluminum, aluminum alloy,
Can be made from resin, FRP, ceramics, etc.
The head body 12 can be made of aluminum, aluminum alloy, iron, stainless steel, brass, etc., and the connecting rod 14 must have a strength that will not easily bend during use or storage in a carry bag. Any material may be used as long as it is desirable and satisfies such requirements.

On the other hand, it is desirable that the weight body 15 has a weight that balances the weight with the head body 12. The weight body 15 can be made of aluminum, brass, iron, or stainless steel, but it can also be made of an actual golf ball with a core material such as lead inserted into it, or a golf ball with resin around the core material. It is possible to use a product molded into approximately the same shape as the above.

In the putter club head having the above configuration, the golf ball 16 and the weight body 15 are
By aligning the straight line connecting these lines with the target direction of the ball 16, the direction of the face plate 11 can be easily aligned with the target direction of the ball 16.

Furthermore, since the weight body 15 is connected to the head body 11 via the elongated connecting rod 14, the weight of the head is concentrated on the face plate 11 side and the weight body 15 side, and is distributed at a location away from the center of gravity of the head. You will have to concentrate. Therefore, the moment of inertia around the center of gravity of the head increases, making it easier to maintain the orientation of the face plate 11 set at address during the swing, and making it easier to direct the orientation of the face plate 11 to the target direction of the roll of the ball 16 when hitting the ball. You will be able to match it.

In addition, since the head main body 12 and the weight body 15 are connected by a long and thin connecting rod 14 that does not affect the weight of the head very much, by making the connecting rod 14 long, the weight body 15 can be connected to the head body 12 while suppressing an increase in the weight of the entire head as much as possible. The distance between the head body 12 and the head body 12 can be increased. Therefore, the fan-shaped plane formed by the grip-side end of the club shaft 13, the head body 12, and the weight body 15 can be made larger, and it becomes easier to keep the plane in the target direction of the ball during the swing, so that the face It becomes easier to keep the direction of the plate 11 in the target direction of rolling of the ball 16.

FIG. 4 shows another embodiment of the present invention. In the figures, the same reference numerals are given to the same components as in the above embodiment. In this embodiment, the weight body 15 is a cylindrical body having a diameter substantially the same as the diameter of the golf ball 16. The other configurations are the same as those of the above embodiment. This embodiment also provides the same effects as those of the above embodiment.

Although the illustrated embodiments have been described above, the present invention is not limited to the embodiments described above, and the shapes of each component may be varied within the scope of the invention described in the claims for utility model registration. Changes can be made. For example, the weight body may have a cubic shape having a width that is approximately the same as the diameter of a golf ball. Further, the face plate and the head body may be formed integrally. Furthermore, the weight body may be mounted on the connecting rod so that its position can be adjusted. Further, the head body may be a spherical body having approximately the same size and shape as a golf ball.

[Effects of the invention] As is clear from the above explanation, according to the invention, by aligning the straight line connecting the golf ball and the weight body with the rolling target direction of the ball at address, it is possible to easily change the direction of the face plate toward the ball. can be adjusted to the target direction. In addition, the center of gravity of the head is on the connecting rod, and the weight of the head is concentrated on both ends of the connecting rod, that is, on the face plate and the weight body that are far from the center of gravity of the head. Therefore, the moment of inertia around the center of gravity of the head is Compared to a head with become able to. Therefore, it is possible to provide a putter club head that can easily keep the face plate in the target direction of the ball not only at address but also during swing.
