Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a golf club head having a hollow outer shell structure made of a light metal such as pure titanium or a titanium alloy, and in particular, by devising the internal structure of the head main body, The present invention relates to a golf club head that improves the feel at impact and improves the flight distance of a golf ball.
[0002]
[Prior art]
Conventionally, in this type of golf club head, for example, a plurality of reinforcing ribs are provided in a head body cast and formed of, for example, an aluminum alloy, or disclosed in Japanese Utility Model Publication No. 61-33970 shown in FIG. As shown, the head body 21 is press-molded into a plurality of outer shell members using titanium or a titanium alloy, and the outer shell members are joined together by welding or the like. A golf club head 20 having a configuration in which a reinforcing rib member 26 is provided to prevent deformation of the face portion 23 from stress during hitting is known.
[0003]
Furthermore, recently, a tendency to favor large-capacity golf club heads using a titanium alloy forged outer shell member has become remarkable, so that even those with a small thickness and a head body volume exceeding 270 cc have started to appear on the market. .
[0004]
These large-sized heads are easy for beginners to just meet golf balls, and the demand is increasing. However, the head outer shell member becomes thinner and the ball hitting sound tends to be lower when the head volume is increased. However, there was a tendency to be far from the generally preferred high metal sound.
[0005]
[Problems to be solved by the invention]
In the golf club head having such a conventional structure, each reinforcing rib provided in the head body formed of an aluminum alloy by the lost wax precision casting method has a face portion, a crown portion, a peripheral side wall portion, and a sole portion. In particular, the purpose is to reinforce the face part and the crown part, but in the molding by the lost wax precision casting method, the thickness design is naturally limited at the design stage, Since a thin member cannot be formed, there is a problem that a large-sized head body cannot be formed.
[0006]
Further, an L-shaped reinforcing rib member 26 provided in the head main body 21 formed by pure titanium or titanium alloy formed on a plurality of outer shell members by forging or pressing and integrally joined by welding or the like, Since it is welded across the back surface of the face portion 23 and the inner surface of the sole portion 24, the purpose is to reinforce the welded portion.
[0007]
For this reason, each of the golf club heads 20 described above has a disadvantage that the hitting sound at the time of hitting is suppressed by the reinforcing rib member 26 or the reinforcing member provided in the head main body 21 and the hitting sound and hit feeling are inferior. It was.
[0008]
Further, in order to improve the hitting sound of a golf club head having a large head volume, which has recently been popular, as disclosed in Japanese Patent Laid-Open No. 10-24128 shown in FIG. A golf club head characterized in that the adjusting member 27 is provided in a separated state having a gap 28 with respect to the face portion 23, the crown portion 25 and the peripheral side wall portion 22 is also known.
[0009]
Further, as disclosed in Japanese Patent Laid-Open No. 11-347156 shown in FIG. 15, the shape of the lower surface of the weight addition plate piece 29 joined to the inner surface of the sole portion 24 is substantially the same shape as the curved surface of the inner surface of the sole portion 24. A golf club head 20 characterized by being formed is also known.
[0010]
Certainly, with respect to the golf club head 20 disclosed in JP-A-10-24128, the vibration of the sole portion 24 is suppressed by the acoustic adjustment member 27 and the effect of improving the hitting sound can be exhibited. Since the sole portion 24 is welded from the face portion 23 to the back face portion 30, the clearance 28 between the acoustic adjustment member 27 and the face member 23 is, for example, in the range of 3 mm to 10 mm, preferably 5 to 8 mm. However, since the rigidity of the rear part 24A of the face part of the sole part 24 is increased, the coefficient of restitution of the face part 23 is reduced, and the flying distance of the golf ball itself is reduced. . Further, with respect to the golf club head 20 disclosed in JP-A-11-347156, the weight addition plate piece 29 is formed in substantially the same shape as the curved surface on the inner surface of the sole portion 24 over the inner region of the sole portion 24. Therefore, the vibration of the sole portion 24 is suppressed by the weight addition plate piece 29 and the hitting sound is improved, but conversely, by joining the weight addition plate piece 29, the rigidity of the sole portion 24 is remarkably increased. The problem that the rebound characteristics of the face portion 23 that is most influenced by the rigidity of the rear portion 24A of the face portion of the sole portion 24 is remarkably affected, the rebound characteristics of the head body 21 are remarkably hindered, and the flight distance of the golf ball is reduced. Had a point.
[0011]
In these golf club heads disclosed in Japanese Patent Laid-Open Nos. 10-24128 and 11-347156, the rigidity of the sole portion at the rear of the head body face portion is increased, but the sole portion and the side wall portion. The rigidity between the outer peripheral portions could not be improved with both of these structures.
[0012]
In addition, the weight addition plate piece may lower the natural frequency at the time of hitting the ball. In particular, the mounting position of the weight addition plate piece has an adverse effect on the rebound of the face part, and the impact sound is greatly improved. It had the problem that the effect was not obtained.
[0013]
In view of these conventional drawbacks, an object of the present invention is to provide a golf club head capable of obtaining a comfortable hitting sound without sacrificing a flight distance or head performance.
[0014]
[Means for Solving the Problems]
In order to solve these problems, the present invention provides, for example, a face member, a crown member, a hosel member, and a sole that are formed into a plurality of three-dimensional curved surfaces by forging or pressing a rod-like or plate-like light metal material. A golf club head in which a head body having a hollow outer shell structure composed of a back face member is integrally joined, and a material for forming an outer shell member of the head body on an upper surface in a sole portion of the head body; A hitting sound control member made of the same material and having a thickness of 1 to 5 mm and a height of 3 to 50 mm is provided in a separated state with respect to the face portion, crown portion and hosel portion, and the side wall portion and Is a golf club head characterized by a joint-integrated structure.
