Description

本発明は、中空構造を有するゴルフクラブヘッドに関し、更に詳しくは、異種素材を複合することで、振動減衰性と心地よい打音の両方を兼ね備えるようにしたゴルフクラブヘッドに関する。   The present invention relates to a golf club head having a hollow structure, and more particularly, to a golf club head that combines both vibration damping properties and comfortable sound by combining different materials.

ゴルフクラブヘッドでは、飛距離や方向性等の性能や強度を改善することに加えて、打球時の振動を減衰し、更には打球時に心地よい打音を発することが要求される。これは、メンタルスポーツでもあるゴルフでは微妙な振動や打音が結果に大きな影響を及ぼすからである。   In addition to improving performance and strength such as flight distance and directionality, a golf club head is required to attenuate vibrations at the time of hitting and to generate a comfortable hitting sound at the time of hitting. This is because in golf, which is also a mental sport, subtle vibrations and hitting sounds have a great influence on the results.

従来より、繊維強化プラスチック（ＦＲＰ）からなる中空構造のゴルフクラブヘッドが開示されている（例えば、特許文献１参照。）。このようなＦＲＰ製のゴルフクラブヘッドは、振動減衰性は良いものの、打球音と飛距離の面で不利である。また、異種素材を複合してなるゴルフクラブヘッドが開示されている（例えば、特許文献２及び特許文献３参照。）。しかしながら、これらゴルフクラブヘッドは振動減衰性と心地よい打音の両方を兼ね備えたものではなかった。
特開平１１−４９１９号公報 特開平５−１６８７３１号公報 特開２０００−２２９１３５号公報 Conventionally, a golf club head having a hollow structure made of fiber reinforced plastic (FRP) has been disclosed (see, for example, Patent Document 1). Such an FRP golf club head has a good vibration damping property, but is disadvantageous in terms of a hitting sound and a flight distance. In addition, golf club heads formed by combining different materials are disclosed (see, for example, Patent Document 2 and Patent Document 3). However, these golf club heads do not have both vibration damping properties and comfortable hitting sounds.
Japanese Patent Laid-Open No. 11-4919 Japanese Patent Laid-Open No. 5-168731 JP 2000-229135 A

本発明の目的は、異種素材を複合することで、振動減衰性と心地よい打音の両方を兼ね備えることを可能にしたゴルフクラブヘッドを提供することにある。   An object of the present invention is to provide a golf club head capable of combining both vibration damping properties and a comfortable hitting sound by combining different materials.

上記目的を達成するための本発明のゴルフクラブヘッドは、中空構造を有するゴルフクラブヘッドにおいて、ネック部、フェース部、ソール部、クラウン部及びサイド部を構成する金属製の外殻部材と、ヘッド全体での質量比率が４％以上４８％以下となる繊維強化プラスチック製の外殻部材とを備え、前記金属製の外殻部材のクラウン部に前記繊維強化プラスチック製の外殻部材を積層したことを特徴とするものである。 To achieve the above object, a golf club head according to the present invention is a golf club head having a hollow structure, a metal outer shell member constituting a neck portion, a face portion, a sole portion, a crown portion and a side portion, and the head An outer shell member made of fiber reinforced plastic having a total mass ratio of 4% to 48%, and the outer shell member made of fiber reinforced plastic is laminated on a crown portion of the outer shell member made of metal. It is characterized by.

このように中空構造を有するゴルフクラブヘッドにおいて、ネック部、フェース部、ソール部、クラウン部及びサイド部を構成する金属製の外殻部材と、上記質量比率となる繊維強化プラスチック製の外殻部材とを備え、金属製の外殻部材のクラウン部に繊維強化プラスチック製の外殻部材を積層することにより、振動減衰性と心地よい打音の両方を兼ね備えたゴルフクラブヘッドを構成することができる。 In such a golf club head having a hollow structure, a metal outer shell member constituting the neck portion, face portion, sole portion, crown portion and side portion, and a fiber reinforced plastic outer shell member having the above-mentioned mass ratio , And by laminating a fiber reinforced plastic outer shell member on the crown portion of the metal outer shell member, a golf club head having both vibration damping properties and comfortable hitting sound can be configured.

本発明において、金属としては、２種以上の金属を互いに異なる部位に使用しても良い。繊維強化プラスチックとしては、２種以上の繊維強化プラスチックを互いに異なる部位に使用しても良い。繊維強化プラスチックの繊維の弾性率が２７ton/mm2 未満である場合には、特に振動減衰性の改善効果が大きくなり、繊維強化プラスチックの繊維の弾性率が２７ton/mm2 以上である場合には、特に打音の改善効果が大きくなる。 In the present invention, as the metal, two or more kinds of metals may be used at different sites. As the fiber reinforced plastic, two or more kinds of fiber reinforced plastics may be used in different parts. When the elastic modulus of the fiber of the fiber reinforced plastic is less than 27 ton / mm 2 , the effect of improving the vibration damping is particularly great, and when the elastic modulus of the fiber of the fiber reinforced plastic is 27 ton / mm 2 or more. Especially, the effect of improving the hitting sound is increased.

以下、本発明の構成について添付の図面を参照しながら詳細に説明する。
図１（ａ）〜（ｃ）は本発明の実施形態からなるゴルフクラブヘッドを示すものである。図１（ａ）〜（ｃ）に示すように、本実施形態のゴルフクラブヘッドは、ネック部１、フェース部２、ソール部３、クラウン部４及びサイド部５を構成する金属製の外殻部材Ｘからなる中空構造を有し、そのクラウン部４に繊維強化プラスチック（斜線部）製の外殻部材Ｙを積層したものである。 Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
FIGS. 1A to 1C show a golf club head according to an embodiment of the present invention. As shown in FIGS. 1A to 1C, the golf club head according to this embodiment includes a metal outer shell that forms a neck portion 1, a face portion 2, a sole portion 3, a crown portion 4, and a side portion 5. It has a hollow structure composed of the member X, and an outer shell member Y made of fiber reinforced plastic (shaded portion) is laminated on the crown portion 4.

このようにネック部１、フェース部２、ソール部３、クラウン部４及びサイド部５を構成する金属製の外殻部材Ｘからなる中空構造においてクラウン部４に繊維強化プラスチック製の外殻部材Ｙを積層することにより、振動減衰性と心地よい打音の両方を兼ね備えたゴルフクラブヘッドを構成することができる。但し、上記繊維強化プラスチックの質量比率〔（ＦＲＰ質量／ヘッド全体の質量）×１００〕は４％以上とすることが必要である。この繊維強化プラスチックの質量比率が４％未満であると振動減衰性と打音の改善効果が十分に得られない。なお、繊維強化プラスチックの質量比率の上限は４８％にすることが好ましい。この範囲内にすることによって、ゴルフクラブヘッドの重心位置をより好適に保つことが可能になる。 Thus, in the hollow structure composed of the metallic outer shell member X constituting the neck portion 1, the face portion 2, the sole portion 3, the crown portion 4 and the side portion 5, the outer shell member Y made of fiber reinforced plastic is provided in the crown portion 4. By laminating, it is possible to configure a golf club head having both vibration damping properties and a comfortable hitting sound. However, the mass ratio [(FRP mass / total mass of the head) × 100] of the fiber reinforced plastic needs to be 4% or more. If the mass ratio of the fiber reinforced plastic is less than 4%, sufficient effects of improving vibration damping and hitting sound cannot be obtained. The upper limit of the mass ratio of the fiber reinforced plastic is preferably 48%. By making it within this range, it becomes possible to keep the position of the center of gravity of the golf club head more suitably.

金属としては、チタン、チタン合金、ステンレス鋼等を使用することができる。また、２種以上の金属を互いに異なる部位に使用するようにしても良い。   As the metal, titanium, titanium alloy, stainless steel, or the like can be used. Also, two or more kinds of metals may be used in different parts.

繊維強化プラスチックとしては、炭素繊維、ガラス繊維、アラミド繊維等の強化繊維に、エポキシ樹脂、不飽和ポリエステル樹脂、ビニルエステル樹脂等のマトリックス樹脂を含浸させてなる繊維強化プラスチックがあり、特に炭素繊維を強化繊維とするものが好ましい。また、２種以上の繊維強化プラスチックを互いに異なる部位に使用するようにしても良い。繊維強化プラスチックの繊維の弾性率が２７ton/mm2 未満である場合には、振動減衰性の改善効果が大きくなり、繊維強化プラスチックの繊維の弾性率が２７ton/mm2 以上である場合には、打音の改善効果が大きくなる。 As fiber reinforced plastics, there are fiber reinforced plastics made by impregnating carbon fibers, glass fibers, aramid fibers, etc. with matrix resins such as epoxy resins, unsaturated polyester resins, vinyl ester resins. What makes a reinforced fiber is preferable. Further, two or more kinds of fiber reinforced plastics may be used in different parts. When the elastic modulus of the fiber of the fiber reinforced plastic is less than 27 ton / mm 2 , the effect of improving vibration damping becomes large, and when the elastic modulus of the fiber of the fiber reinforced plastic is 27 ton / mm 2 or more, The effect of improving the hitting sound increases.

クラウン部４を構成する繊維強化プラスチック製の外殻部材Ｙは、ネック部１、フェース部２、ソール部３及びサイド部５を構成する金属製の外殻部材Ｘに対して接着することができる。 The fiber-reinforced plastic outer shell member Y constituting the crown portion 4 can be bonded to the metal outer shell member X constituting the neck portion 1, the face portion 2, the sole portion 3 and the side portion 5. .

中空構造を有するゴルフクラブヘッドにおいて、ネック部、フェース部、ソール部、クラウン部及びサイド部の構成材料を表１のように種々異ならせた比較例１〜２及び実施例１をそれぞれ作製した。表１において、「Ｔｉ」はチタン又はチタン合金、「ＦＲＰ」は繊維強化プラスチックを意味する。また、「２７ｔ未満」は繊維の弾性率が２７ton/mm2 未満の繊維強化プラスチック（繊維：カーボン）の使用を意味する。なお、金属とＦＲＰとを併記したものは、金属上または下にＦＲＰを積層した場合である。 In the golf club head having a hollow structure, Comparative Examples 1 to 2 and Example 1 in which the constituent materials of the neck portion, the face portion, the sole portion, the crown portion, and the side portion were varied as shown in Table 1 were produced. In Table 1, “Ti” means titanium or a titanium alloy , and “FRP” means fiber reinforced plastic. Further, "less than 27t" elastic modulus of the fiber is 27ton / mm 2 less than the fiber-reinforced plastic (fiber: carbon) refers to the use of. In addition, what described metal and FRP together is a case where FRP is laminated | stacked on or under the metal.

これらゴルフクラブヘッドを装着したゴルフクラブをそれぞれ用意し、１０人のゴルファーによる試打を通して振動減衰性と打音を評価し、その結果を表１に併せて示した。これら評価結果は、比較例１を１００とする指数にて示した。振動減衰性については指数値が大きいほど振動減衰効果が大きいことを意味し、打音については指数値が大きいほど良好であること、つまり金属音とパーシモンによる打音との中間的な打音を発生することを意味する。   Golf clubs equipped with these golf club heads were prepared, and vibration damping and hitting sound were evaluated through trial hits by 10 golfers. The results are also shown in Table 1. These evaluation results are shown as an index with Comparative Example 1 as 100. The greater the exponent value, the greater the vibration damping effect, and the higher the exponent value, the better the vibration damping. In other words, the sound hitting between metal sound and persimmon sound is better. It means to occur.

この表１から判るように、実施例１のゴルフクラブヘッドは、いずれも比較例１に比べて、振動減衰性及び打音が改善されていた。比較例２は繊維強化プラスチックの使用量が少ないため十分な効果が得られなかった。 As can be seen from Table 1, the golf club head of example 1 are all compared with Comparative Example 1, vibration damping and tapping sound was improved. In Comparative Example 2, a sufficient effect was not obtained because the amount of the fiber reinforced plastic used was small.
