Abstract

PROBLEM TO BE SOLVED: To reinforce a crown part and a face part without increasing largely the wt. by forming a continuous reinforcing ribs in the inner face of a head from the crown part to the face part of a wood type golf club head and specifying respectively the lengths of the reinforcing ribs and the no. of the reinforcing ribs. SOLUTION: In a hollow wood type golf club head 1 made of a metal, a plurality of reinforcing ribs 5... are arranged in parallel and at an equal interval on the inner face 1a of the head from the crown part 2 to the face part 3. In these reinforcing ribs 5, when the length of the reinforcing ribs of the crown part 2 is Lc and the length of the reinforcing ribs of the face part is Lf and the no. of the reinforcing ribs 5... are N, in case where the head vol. V is at least 240 cc, setting is made as 7 mm<=Lc <=20 mm, 7 mm<=Lf <=25 mm and 4<=N<=8. On the other hand, when the head vol. V is less than 240 cc, the setting is made as 7 mm<=Lc <=20 mm, 7 mm<=Lf <=height of the face and 4<=N<=8. It is possible thereby to realize the reinforcement of the thin crown and face parts 2 and 3.

2. Description of the Related Art Conventionally, as a material for a wood type golf club head, persimmon (wood), stainless steel, or the like has been used, but a great change in shape could not be made due to restrictions on the strength and specific gravity of the material. However, since the head is made of a low specific gravity material such as titanium, a titanium alloy, and an aluminum alloy, the degree of freedom in designing the head is increased, and a light and large head can be manufactured.

In order to increase the size of a head using the above-described low-specific-gravity material, it is necessary to reduce the thickness of each part of the head to reduce its weight. In particular, to reinforce the face that is the ball striking surface,
As shown in FIG. 5, a head a having reinforcing ribs b at a face portion f and a back face portion on the inner surface of the head is manufactured.

In order to further increase the size of the head, it is necessary to review the thickness distribution of the head and reduce the weight of the head. Therefore, when the face portion f and the crown portion c are made thinner, not only the deformation of the face portion f but also the front edge of the crown portion c that is in contact with the face portion f is greatly deformed when hit with a ball. Problems arise. Normally, in order to reinforce the face part f, FIG.
As shown in the figure, approximately three face heights (about 45mm)
Are provided on the inner surface of the head of the face portion f.

However, in order to reduce the weight, it is difficult to ignore the weight of the ribs b.
No great effect could be expected in suppressing the deformation of the crown c. Therefore, the present invention solves such a conventional problem, and realizes reinforcement of a thin crown portion and a face portion without greatly increasing the weight of the entire head, and reduces the durability of the head. It is another object of the present invention to provide a golf club head capable of further reducing the weight and size of the head.
