Description

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、更に詳しくは金属材料を主材とする中空構造のクラブヘッドにおいて、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。   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, and more particularly, in a hollow structure club head mainly made of a metal material, and made of a metal that emits a resonance sound when hitting a ball. The present invention relates to a golf club head in which a resonator is incorporated to improve the feeling at the time of hitting the ball, and at the same time, the depth of center of gravity of the club head and the moment of inertia around the center of gravity of the head can be increased.

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）。   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. Club heads and club heads mainly made of metal materials such as titanium and stainless steel are known (for example, see Patent Document 1).

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）。   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).

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。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。   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. 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.

また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。The hollow synthetic resin club head and metal wood golf club head have been designed to lower the center of gravity by attaching the weight body to the sole side. There was a problem that a good shot feeling and hitting sound could not be obtained.

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、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。     The present invention was devised by paying attention to such conventional problems, can improve the hitting sound and feel at the time of hitting, and can increase the depth of center of gravity of the club head and the moment of inertia around the head. An object of the present invention is to provide a golf club head capable of reducing the center of gravity.

この発明は上記目的を達成するため、この発明の第１のゴルフクラブヘッドは、中空構造のクラブヘッド本体から成るゴルフクラブヘッドにおいて、前記クラブヘッド本体の外殻及びソール部を金属材料により一体的に構成し、中空構造のクラブヘッド本体内部のソールプレート内側のトウ側、ヒール側、バック側の何れかの一箇所以上に、打球時に共鳴音を発する金属製の共鳴体を少なくとも一つ以上内蔵させて構成し、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たことを要旨とするものである。 In order to achieve the above object , the first golf club head of the present invention is a golf club head comprising a club head body having a hollow structure, wherein the outer shell and the sole portion of the club head body are integrated with a metal material. At least one metal resonator that emits a resonance sound at the time of hitting is incorporated in one or more of the toe side, heel side, and back side inside the sole plate inside the hollow club head body. The gist of the present invention is that the metal resonator is made of a material having a higher specific gravity than the material of the club head body .

ここで、前記クラブヘッド本体の材料よりも高比重材料を用いた金属製の共鳴体を、クラブヘッド本体内部のソールプレート内側のトウ側、ヒール側、バック側の何れかの一箇所以上に、溶接またはソールプレートの鋳造時に一体的に設けるものである。 Here, a metal resonator body using a material having a higher specific gravity than the material of the club head body is placed on one or more of the toe side, the heel side, and the back side inside the sole plate inside the club head body. It is provided integrally when welding or casting the sole plate.

上記のように構成することで、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。   By configuring as described above, the feeling at the time of hitting the ball can be improved, the depth of the center of gravity of the club head and the moment of inertia around the head can be increased, and the center of gravity can be further lowered.

この発明は、クラブヘッド本体の外殻及びソール部を金属材料により一体的に構成し、中空構造のクラブヘッド本体内部のソールプレート内側のトウ側、ヒール側、バック側の何れかの一箇所以上に、打球時に共鳴音を発する金属製の共鳴体を少なくとも一つ以上内蔵させて構成し、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たことにより、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る上に、クラブヘッドの低重心化も図ることが出来る効果がある。 In the present invention, the outer shell and the sole portion of the club head body are integrally formed of a metal material, and at least one of the toe side, the heel side, and the back side inside the sole plate inside the hollow club head body In addition, at least one metal resonator that emits a resonance sound at the time of hitting the ball is built in, and the metal resonator is made of a material having a higher specific gravity than the material of the club head body. In addition to improving the feeling (ball hitting sound and feel), the depth of the center of gravity of the club head and the moment of inertia around the head can be increased, and the center of gravity of the club head can be lowered.

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。   Embodiments of the present invention will be described below with reference to the accompanying drawings.
