Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] This invention relates to a wood golf club head mainly composed of a synthetic resin such as fiber reinforced plastic, and more specifically, a sole plate is firmly fixed to a head body. The present invention relates to an improvement in a wood golf club head in which the life of the club head is extended and weight portions are disposed on the toe side and the back side of the head body to facilitate enlargement and adjustment of a sweet area.

[Conventional technology]

Conventionally, as shown in FIG. 7, a sole plate 2 previously formed into a predetermined shape is attached to a sole portion of a wood golf club head mainly made of a synthetic resin such as fiber reinforced plastic after molding the head body 1 as shown in FIG. It is fixed to the head main body 1 with a wood screw 3 or the like.

[Problems to be Solved by the Invention] However, in the case of the conventional structure as described above, the fixing force between the sole plate and the head body 1 is weak,
When the club head is used, there is a problem that the sole plate 2 is separated from the head main body 1 and floats up. Further, since the sole plate 2 is a thin plate having a thickness of 2.0 to 3.5 mm, there is a risk that the sole plate 2 may be deformed by repeated hitting. Further, if the sole plate and the head main body are not firmly fixed, there is also a problem that loss is likely to occur even in effectively transmitting the kinetic energy of the club head at the time of hitting the ball to the ball.

[Purpose of the invention]

The present invention has been devised in view of such a conventional problem. The sole plate can be firmly fixed to the head main body in the entire frame, and the failure of the sole plate is reduced to extend the life of the club head. It is another object of the present invention to provide a wood golf club head which can easily enlarge and adjust a sweet area of the club head.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a wood golf club head in which a metal sole plate is attached to the bottom surface of a synthetic resin head body, a beam extending from the toe in the heel direction and a beam extending from the intermediate portion to the back side. A substantially T-shaped beam member is formed from the beam, and a weight portion is integrally formed at each of the toe side end and the back side end of the beam member,
A frame having a configuration in which a hosel portion is integrally formed on a heel side end is integrally formed on an inner surface of the sole plate.

Further, the frame is made of a light metal material made of aluminum, titanium, magnesium or an alloy thereof.

[Action of the invention]

The present invention is configured as described above, and the sole plate is integrally fixed to the head main body through the entire frame, so that the sole plate and the head main body can be firmly fixed. And the damage can be reduced, the life of the club head can be extended, and the weight area is arranged on the toe side and the back side of the head body of the beam, so that the sweet area of the club head can be expanded and adjusted. In addition, since the sole plate is firmly and integrally fixed to the head body, energy loss at the time of hitting the ball is small, and a long flight distance can be expected.

[Example of the invention]

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

The same components as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 1 is a front view of a wood golf club head mainly made of a synthetic resin such as fiber reinforced plastic or the like embodying the present invention, FIG. 2 is a longitudinal sectional front view of a club head body 1, and FIG. FIG. 1 is a cross-sectional view taken along the line III-III of FIG. 1, and the sole portion 4 is integrally fixed when the head body 1 is formed.

As shown in FIGS. 4 to 6, the sole plate 2 constituting the sole portion 4 is a substantially T-shaped beam in which a hosel portion 5 is integrally formed on an inner surface 2a of the sole plate 2. The frame 8 is formed by integrally forming the member 6 and the weight portions 7a and 7b on the toe side 1a and the back side 1b of the head body 1 of the beam member 6.

The beam member 6 is formed in a substantially T-shape from a beam extending from the toe in the heel direction and a beam extending from the intermediate portion to the back side. Since the beam member 6 complements the strength of the sole plate, the sole plate can be made thinner and lighter, and can be made lighter and easier to handle while retaining the characteristics of a wood golf club having a large head volume.

The frame 8 is made of a lightweight metal material such as aluminum, titanium, magnesium or an alloy thereof. The sole plate 2, the hosel part 5, the beam member 6 and the weight parts 7a, 7b are integrally formed by casting, or the sole plate 2, the hosel part 5, the beam member 6
Alternatively, the weight parts 7a and 7b may be separately formed and integrally formed by welding or the like. Further, the beam member 6
The weight portions 7a and 7b integrally formed on the toe side 1a and the back side 1b of the head main body 1 are firmly fixed to the head main body 1 so as to be outside the outer shape of the sole plate 2 as shown in FIG. And has an overhang portion 9 protruding therefrom.

Furthermore, by changing the size of the weight parts 7a and 7b,
The club head weight distribution and head weight adjustment can be easily performed.

As described above, the frame 8 in which the sole plate 2, the hosel part 5, the beam member 6, and the weight parts 7a, 7b are integrally formed is made of a fiber-reinforced plastic or the like which forms the outer shell 11 of the head main body 1. They are arranged integrally so as to cover a synthetic resin material and are heated and cured to form an integral structure.

Further, when the outer shell 11 and the weight parts 7a, 7b of the frame 8 are fixed, the overhanging parts 9 of the weight parts 7a, 7b are hooked and fixed to the outer shell 11, so that they can be further firmly fixed.

When the core 12 is incorporated in the head body 1, the fixing of the core 12 to the frame 8 can be performed easily and firmly by fitting, and at this time, an adhesive is used together. It is possible to further firmly fix.

As described above, in the present invention, since the sole plate 2 is integrally fixed to the head main body 1 over the entire frame 8, the sole plate 2 and the head main body 1 can be firmly fixed, and as a result, the thickness is reduced. The failure and damage of the formed sole plate 2 can be reduced, and the life of the club head can be extended.

In addition, by arranging the weight portions 7a and 7b of a predetermined weight on the toe side 1a and the back side 1b of the head body 1 of the frame 8, the sweet area of the club head can be easily enlarged and adjusted, and the sole can be easily adjusted. Since the plate 2 is firmly and integrally fixed to the head main body 1, energy loss at the time of hitting the ball is small, and a long flight distance can be expected.

Further, when the frame 8 is integrally formed by casting of lost wax or the like, distortion and deformation of the sole plate 2 at the time of casting can be suppressed minutely by the arrangement of the beam member 6 and the weight portions 7a and 7b. It can be manufactured with high accuracy.

[Effect of the invention]

As described above, the present invention forms a substantially T-shaped beam member from a beam extending in the heel direction from the toe and a beam extending from the intermediate portion to the back side, and the toe-side end and the back-side end of the beam member are formed. The frame has a structure in which the weight portion is integrally formed on each of the portions and the hosel portion is integrally formed on the heel side end, and the following excellent effects are obtained because the frame is integrally formed on the inner surface of the sole plate. It is.

(A). The sole plate is fixedly attached to the head body via the frame, so that the sole plate and the head body can be firmly fixed, resulting in reduced failure and damage of the thin sole plate. Therefore, the life of the club head can be extended. In addition, since the frame is formed from a substantially T-shaped beam member, it can be firmly attached while keeping the sole plate as thin as possible. The club can be made lightweight and easy to handle without making the club heavy.

(B). By arranging a predetermined weight portion on the toe side and the back side of the head main body of the frame, the sweet area of the club head can be easily enlarged and adjusted.
