【従来の技術】飛距離が重視される所謂ミドルアイアンからロングアイアンに至るクラブは、通常のゴルフプレーヤにとって習熟し難く打ちにくいクラブとされている。 BACKGROUND OF THE INVENTION club ranging from the so-called middle iron that distance is important in the long irons, there is a familiar hard to hard to beat club for regular golf player. これらのアイアンクラブは、一般にヘッド重心の位置がソール面より上方に高くまたフェース面方向の前方に有り打球が上がりにくくしかもスイートエリアが狭くなかなかフェース面の芯に当たらないのがその主な原因とされている。 These iron club is generally the position of the center of gravity of the head does not hit the core of the upward higher The face direction of the easily face surface narrower rises hardly yet sweet area hitting there in front of the sole surface and its main cause It is. 従って、一般のゴルファーはこの種のアイアンクラブをゴルフバックから除いてプレーしていることが多い。 Therefore, the general of the golfer is often're playing with the exception of this kind of iron club from the golf bag.

【0003】 [0003]

【発明が解決しようとする課題】このため、最近では、 [Problems that the Invention is to Solve] For this reason, in recent years,
アイアンクラブのヘッドの形状を大型にしてヘッド重量を周辺に配分し慣性モーメントを増加すると共にフェース面を拡大して打ち損じを少なくしょうとしたり、ウッドクラブとアイアンクラブの中間的な形状のユーティリティクラブのようにヘッド重心を低くまたフェース面の後方に遠く配置して打球を上げ易くしたクラブで代替えしようとした試みが盛んに行われているが、前者は打球の方向性は幾分改善されるが打球を十分に上げて満足できる飛距離を出すまでに至らず、また後者は厳しいラフの中に球が在る場面に遭遇した場合に打ち難い欠点があるなどで、依然として一般ゴルファーにとって、ミドルからロングに至るアイアンクラブの打ち難さの問題が解決されていないのが現状である。 And you'll reduce the Sonji out to expand the face or, wood clubs and iron clubs intermediate shape of the utility club along with the shape of the iron club head in large to increase the allocation to the moment of inertia around the head weight the center of gravity of the head lower also attempts tried alternative in easily club raised hitting placed far behind the face surface is has been actively, the former direction of the hit ball is improved somewhat as there did not reach up to issue a distance satisfactory sufficiently raise the hitting, and the latter in such is hit hard disadvantages when it encounters a scene where there is a sphere in severe rough, still for ordinary golfers, Middlesex the leading to long iron club beat the difficulty of the problem has not been solved from at present.

【0004】上記の実状に鑑みて、本発明の目的とするところは、通常のゴルフプレーヤーにとって打ち易い長距離用のアイアンタイプのゴルフクラブヘッドを提供する事である。 [0004] In view of the above circumstances, it is an object of the present invention is to provide an iron type golf club head for easy long-range strike for the normal golf player.

【0005】 [0005]

【課題を解決するための手段】上記の目的を達成するために、本発明のゴルフクラブヘッドでは、打球面の背面上部に凹部が設けられ、打球面の背面下部に打球面部、 To achieve the above object, according to the solution to ## with the golf club head of the present invention, the recess is provided on the top rear of the ball striking face, the striking face to the bottom rear of the ball striking face,
ソール部、前記打球面部に対面する背壁部及びヘッドの側面によって包囲された上方が前記凹部に開口した空洞部が形成される。 A sole portion, said cavity rear wall and upper surrounded by the side surface of the head is opened to the recess facing the hitting surface is formed.

【0006】前記打球面のロフト角度は、大きな飛距離を得るために従来ミドル及びロングアイアンクラブに一般的な18°〜30°に設定される。 [0006] loft angle of the striking surface is set to a conventional middle and long iron clubs in order to obtain a large distance to a general 18 ° to 30 °.

【0007】また、前記ゴルフクラブヘッドにおいては、ヘッドの重心の位置を最適な位置に設定するために、前記空洞部を包囲するソール部と背壁部の厚さが適宜に加減される。 [0007] In the above golf club head, in order to set the position of the center of gravity of the head to the optimum position, the thickness of the sole portion and the rear wall surrounding the hollow portion is subtracted from the appropriate.

【0008】また、本発明に関わる前記ゴルフクラブヘッドでは、前記背壁部の厚さを、打球面のセンターでの厚さに比較して、トウ側部分もしくはヒール側部分、またはその両側部分において厚く設定される。 [0008] In the above golf club head according to the present invention, the thickness of the back wall portion, compared to the thickness at the center of the ball striking face, the toe-side portion or the heel portion or at both side portions thereof, thick is set. これによってヘッドの重心を通る垂直軸まわりの慣性モーメントが増加され打球の方向性が向上される。 This direction of the hit ball is increased moment of inertia about the vertical axis passing through the center of gravity of the head is improved.

【0009】本発明のゴルフクラブヘッドでは、前記ソール部またはソール部の一部分をヘッド本体と別材料の比重の大きな材料とするためまたそのための製造上の便法から、ヘッド本体のソール側から前記空洞部に向けてソール部に貫通孔が形成され、該貫通孔にヘッド本体と別体に作成されたソール部の少なくとも一部分を嵌着することが出来る。 [0009] In the golf club head of the present invention, a portion of the sole portion or the sole portion from The expedient of manufacturing therefor for a material having a large specific gravity of the head body and another material, said from the sole side of the head main body through hole in the sole portion toward the hollow portion is formed, it can be fitted at least a portion of the sole portion created in the head main body separately from the through hole.

【0010】以上のように構成された本発明に係わるゴルフクラブヘッドにおいては、通常のアイアンクラブの形状を維持しながらも、ヘッドの重心位置を極めて低くまた打球面(即ち、フェース面)に対して後方に深く設定することが出来ることから、通常一般の技量のゴルフプレーヤーであっても、打球の弾道が高く、またフェース面でのスイートエリアが広くてフェース面の芯で球を捕らえ易いことから強い打球を得ることが出来て、飛距離の増大が得られる。 [0010] In the golf club head according to the present invention constructed as described above, to while maintaining normal iron club shape, very low also striking surface center of gravity of the head (i.e., face) Te from the fact that it is possible to deeply set in the rear, even in the golf players of the skill of an ordinary general, a higher trajectory of the ball, also can easy catch the ball in the core of the face and wide sweet area of ​​the face surface since it is possible to obtain a strong hitting, an increase of flight distance is obtained.
