Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a long wood golf club, and more specifically, is it necessary to significantly shorten the length of the neck portion of the club head as compared with the conventional one? The present invention relates to a long wood golf club in which the club head is made large or light in weight, and the degree of freedom in designing the wood golf club is expanded.

[Conventional technology]

In recent years, there has been a tendency to lengthen the shaft of a wood golf club for the purpose of extending the flight distance of a hit ball (generally, a club having a club length of 44 inches or more is called a long wood golf club). Furthermore, this trend is progressing.
From the viewpoint of the ease of hitting a long wood golf club, a larger club head is desirable.

[Problems to be solved by the invention]

However, in the wood golf club 1 whose main material is a synthetic resin material such as fiber reinforced plastic as shown in FIG. 4, there is a limit to structurally increasing the size in order to secure the strength of the club head 1. .

From the results of the trial hit test of the wood golf club, in the case of a club having a length of 44 inches or more, a club head volume of 230 ml or more is preferable from the viewpoint of ease of hitting. However, there is a limitation in increasing the size of the club head 1 due to the weight of the head, and the extension of the current shape is likely to cause a problem in the strength of the club head. There was a problem called difficult.

[Purpose of device]

This invention was devised by focusing on such a conventional problem, and compared with the conventional one, the length of the neck portion of the long wood golf head mainly made of synthetic resin material such as fiber reinforced plastic is longer than that of the conventional one. By significantly shortening it or forming it so that it is almost eliminated, by avoiding damage to the neck part, and by diverting the weight corresponding to the length (la) of the neck part to making the head body large, With the aim of providing a long wood golf club with a larger head size of 230 ml or more, expanding the freedom of club head design, reducing the weight of the club balance, and improving the probability of just the meat for the ball. To do.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention is such that, when the height from the sole bottom of the club head to the upper end of the neck is (h ') and the height of the club head is (h), the sole bottom of the club head is The relationship between the height (h ') to the upper end of the neck and the height (h) of the club head is
Set (h ') ≤ (h) and insert shaft length (la)
Is set in the range of 35 mm to 50 mm, and the club head volume is
The point is that the volume is set to 200 ml or more.

[Function of device]

This invention is configured as described above, and the length of the neck portion of a long wood golf club head mainly made of a synthetic resin material such as fiber reinforced plastic is shortened as compared with the conventional one, or It is formed so as to be almost eliminated, and the weight corresponding to the length of this neck portion is diverted to the large size of the head main body, so that the club head is made large and the degree of freedom in designing the club head is increased, Further, the weight of the club balance is reduced and the probability of the just meet with respect to the ball is improved.

[Example of device]

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a front view of a long wood golf club 10 embodying the present invention. 11 is a club head mainly made of synthetic resin material such as fiber reinforced plastic, 12 is a club shaft, 13 is a club shaft 12 The neck part to which the is attached and 14 is the sole part.

In the embodiment of the present invention, when the height from the sole bottom portion 14a of the club head 11 to the upper end portion of the neck is (h ') and the height of the club head 11 is (h) as shown in FIG. The relationship between the height (h ') from the sole bottom portion 14a of the club head 11 to the upper end portion of the neck and the height (h) of the club head is set to (h') ≤ (h), and the shaft insertion length is set. (La) is set in the range of 35 mm to 50 mm.

The shaft insertion length (la) above is for the club shaft 12
The height (h) of the club head 11 mainly made of fiber reinforced plastic is about 50 mm, and therefore the sole bottom portion 14a of the club head 11 is
The height (h ') from the neck to the upper end of the neck is set to be substantially the same as or lower than the height (h) of the club head 11.
When the height (h) of the club head 11 is exceeded, it does not change much from the conventional one, and the shaft insertion length (la) is 35 mm or more.
This is because the adhesion margin with and decreases, and the adhesive strength and stability are lacking.

It is preferable that the tip of the club shaft 12 penetrates through the shaft insertion hole 15 to the outer surface of the sole at the bottom of the club head 11.

In addition, in this embodiment, the weight corresponding to the omitted length of the neck portion 12 can be diverted to increase the size of the club head 11 to make the volume 230 ml or more, and the volume of the club head 200 ml. With the above, it is possible to set the club balance to C4 or less.

As a result, the club head 11 can be made large, the degree of freedom in designing the club head 11 can be increased, the weight of the club balance can be reduced, and the probability of just meet with the ball can be improved.

Further, FIG. 3 shows a second embodiment of the present invention. In this embodiment, the shaft insertion length (la) is the same as that of the first embodiment.
Was set to approximately the middle of the range of 35 mm to 50 mm,
The second embodiment has a structure in which the shaft insertion length (la) is set to 35 mm.

Since the other operational effects are similar to those of the first embodiment, detailed description thereof will be omitted.

[Effect of device]

According to the present invention, when the height from the sole bottom of the club head to the upper end of the neck is (h ') and the height of the club head is (h) as described above, the bottom of the sole of the club head to the upper end of the neck is The relationship between the height to the part (h ') and the height of the club head (h) is set to (h') ≤ (h), and the shaft insertion length (la) is within the range of 35mm to 50mm. By setting the volume of the club head to 200 ml or more, the following excellent effects are achieved.

(A). Avoids damage to the neck by making the length of the long wood golf club head, which mainly consists of synthetic resin material such as fiber reinforced plastic, much shorter than the conventional one, or almost eliminating it. It can be done.

(B). By diverting the weight corresponding to the length (l) of the neck portion to increase the size of the head body, it is possible to reduce the weight and increase the size of the head to 230 ml or more.

(C). The degree of freedom in designing the club head can be expanded, the weight of the club balance can be reduced, and the probability of just a meet with the ball can be improved.
