Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an iron golf club set, and more specifically, a club head made of a non-metallic material except for a part thereof, and a club head having a non-metallic material at the hitting portion of the head made of a metallic material. The present invention relates to an iron golf club set which is a composite set of club sets.

[0002]

[Prior Art]

 Conventionally, from long iron clubs to short iron clubs, multiple club heads on the long iron side are made of non-metallic material in order to improve the flight distance of the ball depending on its function and to easily control the direction and distance of the ball. The applicant of the present application has proposed an iron golf club set having a composite structure in which the club head on the short iron side is composed of a metal material (Japanese Patent Application No. 61-196832).

That is, in the conventional iron golf club set, on the long iron side, the flight distance is prioritized, and on the short iron side, the control of the hit ball is emphasized so that the respective functions are fully exerted to achieve the hit ball flight distance. And / or the control of the hit ball is made easier. That is, the club on the long iron side (count # 1 to # 3 or # 4) has, for example, a non-metallic material (carbon fiber reinforced plastic), that is, a larger coefficient of restitution than a metallic material, so that the ball has a large elongation. Also, since the coefficient of friction is small, the backspin is small, so the ball rolls, and thus the flight distance can be obtained effectively. On the other hand, in the club on the short iron side (counts # 5 to # 9), the property of the metal material, that is, the friction coefficient is large and the backspin is large, so that the ball does not roll and the control shot is easy to perform effectively. It is configured by using it.

[0004]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional iron golf club set having a composite structure, each function from the middle iron club to the club on the short iron side (count # 5 to # 9), In other words, it is very difficult to design with both functions such as hitting distance and control of hitting, and it is very difficult to have a unified function, and it is very difficult to design with processing adjustment and durability. I had a problem saying it was difficult.

The present invention has been devised in view of such conventional problems, and can sufficiently exhibit the respective functions of the long iron side and the short iron side, and have a connection in each club count. In addition, it is an object of the present invention to provide an iron golf club set which can be integrated into a golf club, which can be easily processed and adjusted and whose durability can be improved.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a plurality of club heads on the long iron side made of a non-metallic material except for a part of the head body, and a plurality of club heads on the short iron side is made of a metal head. The main point is that the ball striking part is made of a non-metallic material.

[0007]

[Function of the device]

 This invention is constructed as described above, and the plurality of club heads on the long iron side are made of a non-metal material such as fiber reinforced plastic except for a part of the head body, and the club head on the short iron side is made of metal. A non-metallic material such as fiber reinforced plastic is attached to or inserted into the ball striking part of the head so that both the distance and the control of the ball can be controlled especially at the club head on the short iron side of the middle iron club. By fully equipping it, it is possible to create a club set with the same functions as an iron club set.

[0008]

Embodiments of the Invention Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of an iron club set embodying the present invention. In this embodiment, the club on the long iron side (counts # 1 to # 5) is L and the club on the short iron side (count # 6 to # 6). # 9, PW) is indicated by S.

The club L on the long iron side and the club S on the short iron side are not limited to the above-mentioned number #, but the number may be slightly mixed or overlapped, and the club L on the long iron side. A golf club called a middle iron club (counts # 5 to # 7) is generally set between the club S on the short iron side.

In the iron club set shown in FIG. 1, 1 is a club shaft, 2 is a grip, 3 is a club head, and 4 is a socket. Next, the structure of each number # will be described with reference to FIGS. 2 and 3 show a front view and a sectional view of the club head 5 of the club L on the long iron side. The club head 5 on the long iron side mounts a core body 7 such as FRP on a metal head 6. However, the outer periphery thereof is covered with an outer shell 8 of fiber reinforced plastic or the like to be integrally molded.

4 to 6 show a front view and a sectional view of the club head 9 of the club S on the short iron side, and a sectional view showing another embodiment. The short iron club S is made of a metal head. A plate material 12 made of a non-metal material such as fiber reinforced plastic as shown in FIG. 5 is attached to the hitting portion 11 of the club head main body 10 or the hitting of the club head main body 10 is performed as shown in FIG. A ball striking member 14 made of a non-metal material such as fiber reinforced plastic is inserted into a hollow portion 13 formed in the portion 11 to be integrally configured.

That is, the club head 9 of the short iron club S is configured by using a non-metal material such as fiber reinforced plastic only in the hitting portion 11 of the club head body portion 10. By configuring in this way, It is equipped with both the functions of a middle iron club and a short iron club S, which are both the distance to be hit and the control of the ball. More specifically, by providing the club head main body 10 made of a metal head on the sole side and the back side of the club head, it becomes easy to design a low center of gravity of the club head, and as a result, it is easy to raise the ball and hit the ball. It is possible to extend the flight distance of the ball by using a non-metallic material having a large coefficient of restitution for the portion 11.

According to the present invention, as described above, the club L on the long iron side and the club S on the short iron side are configured as a set so that the functions of the respective clubs can be sufficiently exerted. It is configured so that it can swing under the same feeling and can effectively demonstrate the function of each count. In particular, it is configured such that the flight distance and control of the ball in the middle iron club and the short iron club S can be sufficiently exerted, and at the same time, the connection with the club L on the long iron side is smoothly made.

[0014]

[Effect of the device]

 In this invention, a plurality of club heads on the long iron side are made of a non-metallic material except for a part of the head body as described above, and a plurality of club heads on the short iron side are formed by hitting a metal head. Since the non-metallic material is provided in the part, it is possible to fully exert the functions of the long iron side and the short iron side, and the golf clubs are unified as a set with connections in each club count. In addition, the processing adjustment is easy, and the durability can be improved.
