【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明はゴルフクラブヘッドに関し、更に詳しくは、ボールの飛距離を伸ばすことができて耐久性に優れたクラブヘツド構造に関する。 The present invention relates to an golf club head, and more particularly, to a Kurabuhetsudo structure having excellent durability to be able to extend the flying distance of the ball.

【0002】 [0002]

【従来の技術】打球時のゴルフボールの初速を高めてボールの飛距離を増大させるためにはボールとクラブヘッドとの反発係数をできるだけ1に近づけることが重要であり、そのためには打球時のヘッドの変形周期をボールの変形周期に同調させることが望ましい。 In order BACKGROUND ART increase the initial velocity of a golf ball hitting increasing the flying distance of the ball is important to close only 1 possible coefficient of restitution between the ball and the club head, at the time of hitting is because the it is desirable to tune the deformation period of the head to the deformation period of the ball. そして、ゴルフボールの質量をm bとし、クラブヘツドの質量をm cとし、ボールの剛性をK bとし、ヘツドの有効剛性をK cとしたとき、打球時にヘツドがボールの変形周期と同調して変形するためには次の数1の同調条件を満たすことが必要である。 Then, the mass of the golf ball and m b, the mass of Kurabuhetsudo and m c, the rigidity of the ball and K b, when the effective stiffness of the head was set to K c, head when hitting is in phase with the deformation of cycles of the ball to deform it is necessary that the following number 1 tuned condition is satisfied.

【0003】 [0003]

【数1】K c =(m c /m b )K b [Number 1] K c = (m c / m b) K b

【0004】今、ボールの質量m bを約46gとし、ヘツドの質量m cを約200g とすると、上記数1から、同調条件を満たすためのボールとヘツドの剛性の関係は、 [0004] Now, the mass m b of the ball was about 46 g, when about 200g mass m c of head, from Equation 1, the relationship between the ball and stiffness head for tuning condition is satisfied,

【0005】 [0005]

【数2】K c =4.3 K b [Number 2] K c = 4.3 K b

【0006】となる。 The [0006]. さらに、打球時のヘツドスピード(即ちボールの初速)を約40m/secとすると、打球時にボールに加わる荷重Pは最大値で約14500Nとなり、実効値で約10000Nになる。 Further, when about 40 m / sec the head speed (i.e. initial speed of a ball) of hitting, the load P applied to the ball hitting about 14500N becomes a maximum value, of about 10000N effective value. したがって、図9に示すように、このときのボールの圧縮変形量δ bは約3.83 Accordingly, as shown in FIG. 9, the amount of compressive deformation [delta] b of the ball lever is approximately 3.83
mmとなり、このときのボールの剛性(割線剛性)K b mm, and the rigidity of the ball at this time (secant stiffness) K b
は次の数3から約2610N/mmであることがわかる。 It can be seen that is about 2610N / mm from the following equation (3).

【0007】 [0007]

【数3】K b =P/δ b [Number 3] K b = P / δ b

【0008】したがって、ヘツドがボールの変形周期と同調して変形するためには、数2および数3より、ヘツドの剛性(割線剛性)K cは約11223N/mm即ち約1145 Accordingly, in order head is deformed in phase with the deformation cycle of the ball, from the number 2 and number 3, the stiffness (secant stiffness) K c of head is about 11223N / mm or about 1145
kg/mmでなければならないことがわかる。 It can be seen that must be kg / mm. また、ヘツドはその弾性域内でボールとの衝突による変形を行なうものでなければならない。 Further, head must performs the deformation due to collision with the ball in its elastic region.

【0009】上記の同調条件を満足するクラブヘッドを実現するための種々の試みがなされてきた。 [0009] Various attempts to achieve a club head that satisfies the above-mentioned tuning conditions have been made. 例えば、クラブヘッド本体のフェース部に形成した開口部に可撓性のフェース体を装着し、このフェース体の撓み変形を利用してボールと同調変形させるものや、クラブヘッド本体のフェース部に装着されるフェース体の背面とヘッド本体の支持面との間にばね手段を介装し、フェース体とボールとの衝突時にこのばね手段をボールと同調変形させるものなどが考えられてきた。 For example, wearing the face portion flexible face body in an opening formed in the club head body, and one which a ball and the tuning deformed by utilizing the bending deformation of the face member, mounted on the face of the club head body It is a spring means between the back and the support surface of the head body of the face body interposed are, like the spring means upon impact with the face body and the ball that is the ball and the tuning variations have been considered. 一方、ヘッド本体のフェース部に形成した凹所にゴム状弾性体層とその表面を覆う繊維強化樹脂層とからなる複合フェース体を固着し、打球時にこの複合フェース体をボールと同調変形させるものが本願発明者等により提案されている。 On the other hand, it secured a composite face material consisting of a fiber-reinforced resin layer which covers the rubber-like elastic body layer and a surface in a recess formed in the face portion of the head body, which is a ball and the tuning deforming the composite face material during hitting There has been proposed by the present inventors.

【0010】 [0010]

【発明が解決しようとする課題】しかしながら、上述した従来のヘツド構造の場合、何れもヘッド本体に対し別部材を組み込むため、ヘツド構造が複雑になり、その製造が困難になると共に、ヘツドの重量配分がフェース面寄りになり、フェース面からのヘツドの重心深度が浅くなってボールの飛びの方向性が悪くなるという問題があった。 [SUMMARY OF THE INVENTION However, in the conventional head structure described above, to incorporate a separate member with respect to both the head body, head structure becomes complicated, the manufacturing becomes difficult, the weight of the head distribution is made to face toward the direction of the ball flight and depth of the center of gravity of the head from the face surface is shallower there is a problem that becomes worse. また、フェース体やばね手段等の固着または係合構造のため、耐衝撃強度や耐久性に乏しいという欠点があった。 Further, since the anchoring or engagement structures such as face body and the spring means it has a disadvantage of poor impact resistance and durability.

【0011】したがって、本発明の目的は、ボールとの同調変形によりボールの飛距離を伸ばすことができ、しかも耐久性に優れたゴルフクラブヘツドを提供することにある。 [0011] Accordingly, it is an object of the present invention, it is possible to extend the flying distance of the ball by tuning deformation of the ball, yet it is to provide a golf club head having excellent durability.
