2. Description of the Related Art Conventionally, as described in Japanese Utility Model Publication No. 63-288, for example, there is known a golf wood club head in which a head body is made of metal and hollow. And, the wood club head described in the above publication has a sole portion, a toe portion, a side peripheral shell portion which is an outer shell member forming a heel portion and a back portion, and a face surface shell portion which is an outer shell member forming a face portion. The upper shell portion, which is an outer shell member constituting the crown portion, is formed by press working or forging, and then welded to each other. The pipe connecting the shaft is welded to the side shell and the upper shell. In addition, welding to the side peripheral shell is performed in the order of the pipe, the face shell, and the upper shell.

However, if all the outer shell members constituting the head main body are formed by pressing or forging, the cost increases and it is difficult to obtain high strength.
In addition, a neck portion to be smoothly continued from the shaft to the crown portion is formed in the upper shell portion. However, in the upper shell portion formed by press working or forging, the shape of the neck portion is limited to a shape having a small radius of curvature. Cannot increase the radius.

[0004] Conventionally, the entire head body has been cast by a lost wax method or the like. However, if the entire head body is manufactured by casting, although the strength can be increased, the thickness cannot be made uniform, and the overall weight distribution tends to vary for each manufactured head. It is also difficult to add functions such as setting a specific weight distribution.

[0005]

As described above, conventionally, when a plurality of outer shell members are welded to form a head body, all of the outer shell members are manufactured by press working or forging. However, there is a problem that it is difficult to obtain high strength as well as the shape of the neck portion is limited. Further, in the method of casting the entire head main body, it is difficult to make the thickness uniform, there is a problem that the weight distribution of the entire head is easily varied, and it is difficult to add a function.

[0006] The present invention is intended to solve such a problem, and is advantageous in that cost can be reduced, a certain degree of strength can be obtained, and quality is stabilized or functions are added. and an object thereof is to provide a Hisage <br/> golf Uddokura drive. Furthermore, with fewer manufacturing processes,
It is an object of the present invention to be able to freely set the shape of a neck portion.

According to the first aspect of the present invention, there is provided a
Golf wood club with head connected to the ft
The head includes a sole, a toe, a heel,
Cast first shell constituting base and back portions

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the golf wood club head of the present embodiment, the head body 1 is made of a hollow metal. This metal is titanium, titanium alloy (specific gravity about 4.6),
Such as stainless steel or other light alloys. The specific gravity is preferably 4.6 or less. In the drawings, reference numeral 2 denotes a sole portion, 3 denotes a toe portion, 4 denotes a heel portion, 5 denotes a face portion, 6 denotes a back portion, 7 denotes a crown portion, 8 denotes a hosel portion, and 9 denotes a neck portion. The hosel portion 8 connects the shaft 10, and around the hosel portion 8,
The neck portion 9 that smoothly connects the crown portion 7 to the crown portion 7
Are formed.

The head main body 1 has a first outer shell member 11 forming a sole portion 2, a toe portion 3, a heel portion 4, a face portion 5 and a back portion 6, and a second outer portion forming a crown portion 7. And an outer shell member 12. The first outer shell member 11 is integrally manufactured by a lost wax method as a casting, and the second outer shell member 12 is manufactured by press working .

Further, the hosel portion 8 includes two outer shell members 11,
It is composed of a metal pipe 13 separate from 12. This
Of the first outer shell member 11 by welding
2 are fixed to both outer shell members 11 and 12. And
Neck that smoothly connects shaft 10 to crown 7
9 is formed by building up at the time of welding.
Further finish processing is performed.

According to the configuration of the above embodiment, a plurality of outer shell portions are provided.
When manufacturing the head body 1 by welding the materials 11 and 12,
Some outer shell members 11 are made by the lost wax method,
Since the other outer shell members 12 were formed by pressing,
Making the best of each of the wax process and press working
Thus, the head body 1 can be manufactured. That is,
The cost method is reduced and the strength is improved
it can. On the other hand, the use of press working has made the thickness uniform
And the weight distribution is stable for each manufactured head.
And stabilize the quality. Also, specific weight distribution
It is relatively easy to add functions such as setting of minutes.
And the sole part 2, the toe part 3, the heel part 4, the face
A first outer shell member 11 constituting the part 5 and the back part 6,
The second outer shell member 12 constituting the crown portion 7 has high strength.
Manufactured by the lost wax method.
Doing is advantageous in strength.

The present invention is limited to the above embodiment.
Instead, various modifications can be made. For example,
In the above-described embodiment, in the manufacture of the outer shell member, the lost washer was used.
We use casting method and press processing by box method,
The casting method by the lost wax method can be replaced with another casting method.
And press working can be replaced by forging.
You.

[0014]

According to the present invention , the head is connected to the shaft.
In a golf wood club, the head is a sole.
Section, toe section, heel section, face section and back section.
Forming a first shell member made of casting and a crown portion.
Second shell member manufactured by forging or pressing
Forming the hosel portion connecting the shaft,
A metal pipe separate from the first and second shell members is provided.
When the pipe is welded to the first and second shell members,
Both are golf wood clubs , wherein a neck portion is formed by the build-up of the welding , and a first outer shell portion
Material is produced by casting and the second shell is forged or pressed.
Because it is manufactured by less processing, the cost can be reduced
In particular, while ensuring quality, especially for parts where strength is required
Et increase the strength is.
