【発明の属する技術分野】
この発明は、中空構造のアイアンゴルフクラブヘッド，ウッドゴルフクラブヘッド等のゴルフクラブヘッドにかかわり、更に詳しくは炭素繊維強化プラスチック（ＣＦＲＰ）を主材とするクラブヘッドの中空部内に、打球時に共鳴音を発する金属製の共鳴体を内蔵させて打球時にフィーリングを良好にすると同時に、クラブヘッドの重心深度やヘッド重心周りの慣性モーメントを大きくでき、更に低重心化も図ることが出来るゴルフクラブヘッドに関するものである。
【０００２】
【従来の技術】
近年市販されている中空構造のアイアンゴルフクラブヘッド，ウッドゴルフクラブヘッドには、外殻が炭素繊維強化プラスチックで構成され、ソール部が金属材料で構成されて一体的に構成された合成樹脂製のクラブヘッドや、チタン，ステンレス等の金属材料を主材としたクラブヘッド等が知られている（例えば、特許文献１参照）。
また、クラブヘッドに発音体または発音機構を有し、クラブフェイスの芯にボールが当たった時に音を発生するゴルフクラブも提案されている（例えば、特許文献２参照）。
【０００３】
【発明が解決しようとする課題】
然しながら、前者の中空構造の合成樹脂製クラブヘッドは、上述したように外殻が炭素繊維強化プラスチック（ＣＦＲＰ）で構成されているため、打球音が極めて小さく、後者の金属材料を主材としたクラブヘッドに比べて打球感（フィーリング）が極めて悪いと言う問題があった。
【０００４】
また、最近のチタン，ステンレス等の金属材料を主材としたメタルウッドゴルフクラブヘッドにおいても、ヘッド本体の体積が大きくなるにつれて肉厚が薄くなり、心地よい打球音が得られないと言う問題があった。
また発音体または発音機構を有するクラブヘッドの場合には、特定箇所に打球した時のみ打撃音が共鳴するものであり、共鳴音は極めて小さい。更に、中空構造の合成樹脂製クラブヘッド及びメタルウッドゴルフクラブヘッドにおいては、重量体をソール部側に取付けることで低重心化を図る設計も行われているが、重量体を取付けることで、更に心地良い打球感や打球音を得ることが出来ないと言う問題があった。

特開平３−２２８７８２号公報
【特許文献２】
特開昭４８−８６６３３号公報
【０００５】
この発明は、かかる従来の問題点に着目して案出されたもので、中空構造のクラブヘッドにおいて、打球時の打球音及び打球感を良好にすると同時に、クラブヘッドの重心深度やヘッド周りの慣性モーメントを大きくでき、更に低重心化も図ることが出来るゴルフクラブヘッドを提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
この発明は上記目的を達成するため、炭素繊維強化プラスチックで構成した外殻と、金属材料で構成したソール部とで中空構造のクラブヘッド本体を一体的に形成し、前記中空構造のクラブヘッド本体内部のソール部に、打球時に共鳴音を発する複数の金属製の棒から成る共鳴体を鉛直向きに立設させて内蔵したことを要旨とするものである。
ここで、前記金属製の共鳴体を、クラブヘッド本体の材料よりも高比重材料を用いるものである。
【０００７】
この発明は、上記のように構成され、炭素繊維強化プラスチック（ＣＦＲＰ）を主材とするクラブヘッド、及びチタン等の金属材料を主材とするクラブヘッドの中空部内に、打球時に共鳴音を発する複数の金属製の棒から成る共鳴体を鉛直向きに立設させて内蔵させて構成することにより、打球時にフィーリングを良好にすると同時に、クラブヘッドの重心深度やヘッド周りの慣性モーメントを大きくでき、更に低重心化も図ることが出来るものである。
【０００８】
【発明の実施の形態】
以下、添付図面に基づきこの発明の実施の形態を説明する。
図１はこの発明の一実施形態を示す炭素繊維強化プラスチック（ＣＦＲＰ）を主材とするウッドゴルフクラブのクラブヘッド本体１の断面図を示し、２は外殻、３はステンレス，鉄等の金属材料で形成されたソールプレートを示している。
【０００９】
前記クラブヘッド本体１の共鳴箱となる中空部４内には、鋼棒等の金属材料から成るＹ字状に形成された共鳴体５や、鋼棒等の金属材料から成る共鳴体５ａが内蔵され、この共鳴体５または共鳴体５ａ、または両共鳴体５，５ａは、ソールプレート３の内側のトウ側３ａまたはヒール側３ｂの２箇所に設けたり、或いは図２に示すように、ソールプレート３の裏面側に複数本立設させて一体的に形成しても良い。
【００１０】
なお、共鳴体５は、上述したように略Ｙ字状に形成して共振体とし、中空部４は共鳴箱として構成するものである。
更に、前記金属製の共鳴体５，５ａを、ソールプレート３に溶接や、ソールプレートの鋳造時に一体的に固定し、金属製の共鳴体を、クラブヘッド本体の材料よりも高比重材料を用いることで、クラブヘッド本体１の重心深度やヘッド周りの慣性モーメントを大きくでき、更に低重心化も図ることも可能である。
また、上記の実施形態は、ウッドゴルフクラブヘッドについて説明したが、中空構造のアイアンゴルフクラブヘッドにも適用することは可能である。
【００１１】
以上のように、炭素繊維強化プラスチック（ＣＦＲＰ）を主材とするクラブヘッド１の中空部４内に、打球時に共鳴音を発する金属製の共鳴体５，５ａを内蔵させて構成することにより、上記のようなクラブヘッド１で打球した際、その打球時の衝撃により音叉である共鳴体５，５ａが振動すると共に、振動音が共鳴箱となる中空部４内において基音（打撃音）の５倍〜１８倍程度になり、打球時のフィーリング（打球音，打球感）を良好にすると同時に、クラブヘッドの重心深度やヘッド周りの慣性モーメントを大きくでき、更に低重心化も図ることが出来るものである。
【００１２】
【発明の効果】
この発明は、上記のように炭素繊維強化プラスチックで構成した外殻と、金属材料で構成したソール部とで中空構造のクラブヘッド本体を一体的に形成し、前記中空構造のクラブヘッド本体内部のソール部に、打球時に共鳴音を発する複数の金属製の棒から成る共鳴体を鉛直向きに立設させて内蔵したので、打球時にフィーリング（打球音，打球感）を良好にすると同時に、クラブヘッドの重心深度やヘッド周りの慣性モーメントを大きくでき、更に低重心化も図ることが出来る効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a golf club head such as an iron golf club head or a wood golf club head having a hollow structure. More specifically, the present invention relates to a resonance sound in a hollow portion of a club head mainly made of carbon fiber reinforced plastic (CFRP). The present invention relates to a golf club head that has a built-in metal resonator that produces a good feeling when hitting and at the same time can increase the depth of center of gravity of the club head and the moment of inertia around the center of gravity of the head, further reducing the center of gravity. Is.
[0002]
[Prior art]
In recent years, commercially available hollow and iron golf club heads and wood golf club heads are made of a synthetic resin in which the outer shell is made of carbon fiber reinforced plastic and the sole part is made of a metal material. and the club head, that has titanium club head that has a metal material such as stainless steel as a main material is known (e.g., see Patent Document 1).
In addition, a golf club having a sounding body or sounding mechanism in the club head and generating a sound when the ball hits the core of the club face has also been proposed (see, for example, Patent Document 2).
[0003]
[Problems to be solved by the invention]
However, the former synthetic resin club head having a hollow structure, as described above, has an outer shell made of carbon fiber reinforced plastic (CFRP), so the hitting sound is extremely small, and the latter metal material is the main material. There was a problem that the feeling of hitting (feeling) was extremely poor compared to the club head.
[0004]
Also, recent metal wood golf club heads mainly made of metal materials such as titanium and stainless steel have a problem that the thickness of the head main body increases and the comfortable hitting sound cannot be obtained. It was.
In the case of a club head having a sounding body or a sounding mechanism, the hitting sound resonates only when the ball is hit at a specific location, and the resonance sound is extremely small. Further, in the synthetic resin club head and the metal wood golf club head having a hollow structure, a design that lowers the center of gravity by attaching the weight body to the sole portion side is also performed, but by attaching the weight body, There was a problem that a comfortable shot feeling and a hitting sound could not be obtained.
[Patent Document 1]
JP-A-3-228787
[Patent Document 2]
JP-A-48-86633
The present invention has been devised by paying attention to such conventional problems. In a hollow club head, the hitting sound and feel at the time of hitting are improved, and at the same time, the center of gravity depth of the club head and the surroundings of the head are improved. An object of the present invention is to provide a golf club head capable of increasing the moment of inertia and further reducing the center of gravity.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention integrally forms a hollow club head body with an outer shell made of carbon fiber reinforced plastic and a sole portion made of a metal material. The gist of the invention is that an internal sole portion is provided with a resonance body composed of a plurality of metal rods that emit resonance sound at the time of hitting the ball in a vertical direction .
Here, a material having a higher specific gravity than the material of the club head body is used for the metallic resonator.
[0007]
The present invention is configured as described above and emits a resonance sound in a hollow portion of a club head mainly made of carbon fiber reinforced plastic (CFRP) and a club head mainly made of a metal material such as titanium when a ball is hit. By constructing a built- in resonator body consisting of multiple metal bars in a vertical orientation , the club head has a good feeling at the time of hitting, and at the same time, the club head depth of gravity and the moment of inertia around the head can be increased. In addition, the center of gravity can be lowered.

【The invention's effect】
According to the present invention, a hollow structure club head body is integrally formed by the outer shell made of carbon fiber reinforced plastic and the sole portion made of a metal material as described above, and the inside of the hollow structure club head body is formed. In the sole part, a resonance body consisting of a plurality of metal rods that emit resonance sound when hitting the ball is built up vertically and built in, so that the feeling (ball hitting sound, feel at impact) can be improved while hitting the club. It is possible to increase the depth of the center of gravity of the head and the moment of inertia around the head, and to lower the center of gravity.
