Description

【発明の詳細な説明】
【0001】
【産業上の利用分野】この発明は、ソール幅がフェース
高さ以上あるメタル材料で形成された、所謂メタルウッ
ドと呼ばれるゴルフクラブヘッドに関する。
【0002】
【従来の技術】従来のヘッド形状は、大別すると丸型と
洋梨型とがあり、上面にクラウン部を有する。メタル材
料は、木やカーボンに比べて圧倒的に重量があるので、
内部を空洞にしてある。内部の空洞を空洞のままにした
ものとウレタン等を詰め込んだものがある。
【0003】
【発明が解決しようとする課題】通常のメタル材料を用
いたクラウン部を有するゴルフクラブヘッドでは、強度
面の配慮からフェース面の厚さを厚くせざるを得ず、重
心位置も高くなっていた。低重心化を図るためにソール
の厚さを厚くして重量を増大させるとヘッド重量が重く
なりすぎて振り切ることが難しくなる。
【0004】そこで、この発明は、ヘッド重量を増大さ
せずに低重心化を図り、フェースセンターとするボール
の打点と重心とを結ぶ線がフェース面と直交するように
設計することができ、フェースセンターでヒットすれば
ボール初速が上り、スピンが少なく飛距離を伸ばすこと
ができ、ボールを上げ易いゴルフクラブヘッドを提供す
ることを目的とする。
【0005】
【課題を解決するための手段】上述の目的を達成するた
め、この発明は、ソール幅がフェース高さ以上あるメタ
ル材料で形成されたゴルフクラブヘッドにおいて、ヘッ
ド上面のクラウン部にメタル材料を配置しないようにし
たものである。
【0006】
【作用】この発明のヘッドと同一重量のクラウン部を有
するヘッドとでは、この発明のヘッドの方が重心位置を
最適の位置に設定することも、周辺重量配分も容易とな
る。その結果、ボールを上げ易く、飛距離増大及び方向
性も安定させることのできるゴルフクラブとなる。
【0007】
【実施例】以下に、この発明の好適な実施例を図面を参
照にして説明する。図1に示すゴルフクラブヘッドは、
従来一般的にあったクラウン部1にメタル材料が存在せ
ず、具体的にはクラウン部1をカットして孔2が形成さ
れている。このゴルフクラブヘッドは、ソール幅がフェ
ース3の高さ以上あるメタル材料で形成された所謂ウッ
ドクラブと呼ばれるものである。クラウン部1がカット
され、この分の重量をソール6に配分すれば低重心化が
容易に図れる。また、ソール6に配分するのみならず周
辺にも配分すれば周辺重量配分も最適なものにすること
ができる。このメタル材料で形成されたヘッドの内部は
空洞にしてあり、この空洞のままでもよいしウレタン等
を詰め込んでもよい。さらに、孔2はそのままでもよい
し、透明な軽量樹脂等のプレート4を図2に示すように
取付けてふさいでもよい。この図2に示す実施例では、
内部の空洞にウレタン5を詰め込んである。フェース3
の肉厚は強度面の配慮から厚くし、低重心化を図るため
にソール6の肉厚も厚くしてある。
【0008】図3は、ヘッドの上面における孔2の大き
さを示し、この孔2の外郭線はヘッドを上面からみたと
きの輪郭線から10mm内側になるようにクラウン部1を
カットした例を示す。このカットした部分の重量約30
gをソール6に配分すると、図4に示すように従来の重
心G′の位置から約4.6mm下がり(図4における符号
Gの位置)、この重心Gとフェース3に直交する線を引
くと、このフェース3に直交する交点がボールBに対し
最適の打点となる。
【0009】図4は従来のクラウン部1を有する種々の
ウッドクラブ(ドライバー)の重心位置とこの発明の実
施例の重心位置を計測した結果を示すグラフである。本
発明実施品は、重心位置が16.5mmであり、他のクラ
ウン部を有する従来のヘッドよりもかなり低重心である
ことが判る。図3に示すようなカットをするとき、クラ
ウン部1の表面積が48cm2 であるクラブヘッドに対し
24cm2 カットした場合、カットされる重量が27gで
あった。表面積が48cm2 あるクラウン部1を有するも
のでは、重心高さは21.1mmであり、クラウン部1を
24cm2 カットし、カットされた27gをソール6に配
分したものでは、重心高さは16.5mmであった。
【0010】
【発明の効果】以上説明したように、この発明によれ
ば、ヘッド上面のクラウン部にメタル材料を配置しない
ことにより、この配置されないメタル材料の重量分をソ
ールに配分することで低重心化を図ることができ、重心
と打点を結ぶ線に重心位置が略一致することとなり、ボ
ール初速が上がり、スピンが少なくなり飛距離が伸び
る。また、低重心であればボールも上がり易い。さら
に、クラウン部に配置されないメタル材料をソールのみ
ならず周辺に配分することにより周辺重量配分を容易に
行え、方向性も安定させることができる。
