Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a golf club head in which a sole plate is firmly integrated with the head body.

[Prior art]

Generally, as shown in FIG. 6, a wood golf club head 1 has a sole plate 2, which is a part that contacts the ground when hitting a ball, and a face 3, which is a part that contacts the ball.

Conventionally, in a wood golf club head in which a sole plate is integrally molded into a head body mainly made of carbon fiber reinforced plastic (CFRP), when the head body and sole plate are integrally molded, the fifth As shown in the figure, a pin 4 with an enlarged head is fixed to the sole plate 2 by caulking or the like, and the pin 4 is integrally molded using the sole plate 2 and embedded in the head body 7 made of CFRP or the like. The sole plate is fixed to the head body by the anchoring effect. (For example, Jitsukaiaki
59-143460).

However, when molding in this manner, there is a problem that the molding pressure may cause the pin 4 to tilt and come out of its fixed position, thereby affecting the strength of the golf club head.

[Purpose of invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a golf club head in which a sole plate is firmly integrated into a head body.

[Structure of the idea]

For this reason, the present invention has a
A plate-shaped fin is fixed in an upright state and buried in the head body, and a notch and a notch hole are formed at the end and/or the middle part of the plate-shaped fin on the sole plate side. This is a summary.

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings. Note that the same parts as in FIGS. 5 and 6 are indicated by the same numbers.

FIG. 1 is an explanatory view showing an example of the state in which the head body and sole plate are fixed to each other in the golf club head of the present invention. In FIG. 1, plate-shaped fins 6 are joined to the inner surface of the sole plate 2. As shown in FIG. This fin 6 is the sole plate 2
It may be perpendicular or inclined. The sole plate 2 and the fins 6 may be joined by partial welding and/or total welding as shown by a in the figure. In addition, sole plate 2 and fin 6
are each made of metal.

The ends and/or middle portions of the fins 6 are partially cut out. In FIGS. 1 and 2, a key-shaped notch 10 is formed at the end of the fin 6. As shown in FIG. In FIG. 3, a cutout hole 11 is formed in the middle part of the fin 6. By partially cutting out the ends and/or the middle part of the fins 6 in this way, the fins 6 can have an anchoring effect and the sole plate 2 can be firmly fixed to the head main body 7.

The fins 6 may have any shape, for example, as shown in FIG. 4, they may be cross-shaped or H-shaped. In the case of a cross-shaped fin, key-shaped notches 10 are preferably provided in at least the four corners of the fins 6 so that the sole plate 2 can be most effectively fixed to the head body 7. Note that the width of the fins 6 is 2 mm or more.

This fixing may be done by a conventional method, for example, by compression molding.

[Effect of idea]

According to the present invention, plate-shaped fins are fixed to the inner surface of the sole plate in an upright state and embedded in the head main body, and the end and/or intermediate portion of the plate-shaped fins on the sole plate side are fixed. Since the cutout and the cutout hole are formed in the cutout, the following effects can be achieved.

Since the head body and the sole plate are integrally fixed, the head body is more durable against impact from hitting a golf ball than conventional pins that are caulked or the like. In addition, because the plate-shaped fins are constructed to stand up against the sole plate,
It is possible to improve the impact resistance of the club bed when hitting a ball. In addition, when fixing with pins, it was necessary to consider the position of the brand stamp etc. on the surface of the sole plate, but in this invention, the fins are attached to the inner surface of the sole plate, so
The position of the stamp of the brand etc. can be freely selected.

The structure of the sole plate can be simplified.

The notches and notched holes in the fins are filled with the resin that makes up the head body, and the fins are firmly buried and fixed in a state that surrounds them.The anchoring effect of the resin makes it possible to further strengthen the adhesion between the sole plate and the head body. Can be fixed securely. Also,
Since the core inside the head body is held in a state where it is fitted into the fins that are erected, the core is stably held in a fixed position even when hitting a ball.
