Description
図1は本発明の実施形態に係るゴルフクラブヘッドの分解斜視図、図2は該ヘッドの正面図、図3はその背面図、図4は図3のA−A位置に相当する断面図をそれぞれ示す。ここで、図4は、クラブヘッド1を規定のライ角及びロフト角αで水平面HPに置いた基準状態であるが、図2及び図3は、その状態からフェース面Fが垂直となるようにヘッドを前傾させた状態をそれぞれ示す。
本発明の効果を確認するために、表1の仕様に基づいてロフト角24度の5番アイアンのクラブヘッド(実施例)を試作した。ヘッド本体には、いずれも比重7.8のステンレス(SUS630)が用いられ、孔部にはタップ加工が施された。また、軸状部材には、熱可塑性ポリウレタンエラストマー(BASF社製の「エラストランC80A」、JIS−A硬さ80度)だけで形成された。さらに、孔部と軸状部材との間に、接着剤(東立化成工業社製のウレタン系接着剤エスプレンH−25)を介在させた。
全てが上記ステンレスからなり、孔部及び軸状部材のないクラブヘッド。
<比較例2>
実施例1をベースとしているが、孔部及び軸状部材は、いずれもネジ山を一切有さず、平滑な表面として上記接着剤のみで両者が固着されたクラブヘッド。
測定方法及びテスト方法は、次の通りである。
先ず、各クラブヘッドにFRP製の同一のシャフトを装着し、プロ及びシングルプレーヤのゴルファー10名により、各供試クラブを用いて天然芝上のボールをそれぞれ10球ずつ打撃し、打球感について、以下の基準で官能評価が行われた。
◎:良いと感じたゴルファーが8名以上
○:良いと感じたゴルファーが5〜7名
△:良いと感じたゴルファーが2〜4名
×:良いと感じたゴルファーが1名以下
各供試クラブがスイングロボットに取り付けられ、ヘッドスピード41m/sでゴルフボール3000球の打撃が行われた。打撃中ないし打撃完了後、軸状部材の外れ、折損等の有無が肉眼で観察された。
次に、図10に示した体積460ccのウッド型のゴルフクラブヘッド(ロフト角)が表2の仕様に基づき試作された。ヘッド本体は、チタン合金(Ti−6Al−4V)のロストワックス鋳造品とし、孔部にはタップ加工が施された。軸状部材やその固着方法は、上記アイアン型のゴルフクラブヘッドの実施例と同じとした。そして、各クラブヘッドについて、打球感及び耐久性がテストされた。
全てが上記チタン合金からなり、孔部及び軸状部材のないクラブヘッド。
<比較例4>
実施例9をベースとしているが、孔部及び軸状部材は、いずれもネジ山を一切有さず、平滑な表面として上記接着剤のみで両者が固着されたクラブヘッド。
テストの結果等を表2に示す。
