Description

本発明は、クラブヘッドに関し、特に重心が低くて振動減衰効果が優れたクラブヘッドに関するものである。   The present invention relates to a club head, and more particularly to a club head having a low center of gravity and an excellent vibration damping effect.

ゴルフをやる時、ボールをできるだけ高くて遠く打つために、ゴルファーのスイング姿勢や打撃力・ゴルフクラブの選択のほか、ゴルフクラブの設計の良否も重要である。ゴルフクラブとしては、そのクラブヘッドのデザインが特に決め手となる。   When playing golf, in order to hit the ball as high and high as possible, the golfer's swing posture, striking force, selection of the golf club, and the quality of the golf club design are also important. As a golf club, the design of the club head is particularly decisive.

クラブヘッドは、キーポイントの一つの材質については、硬ければ硬いほど壊れにくくなるが、ボールを打った後生じる振動を減衰させる効果がよくないので、ボールは激しい振動状態で飛んでいって飛翔のエネルギーが消耗されてしまうため、飛行距離が短縮されるうえ、その振動がゴルファーの手に伝わってけがを負わせることにもなる。   The harder the club head, the harder the material of one of the key points, the harder it is to break, but the effect of dampening the vibrations that occur after hitting the ball is not good. As the energy is consumed, the flight distance is shortened and the vibration is transmitted to the golfer's hand, causing injury.

また、クラブヘッドのもう一つのキーポイント、全体の重心については、重心が高く位置させられたものは、打ったボールの飛行軌跡が低いので、力強いゴルファーだけに適するが、一方、重心が低く位置させられたものは、打ったボールが高く飛びかけるので、力弱いゴルファーにも初心者にも最適である。さらに、重心が打球フェースに近すぎると、インパクト時にクラブヘッドは過激に捻じられてバランスがなくなる。それゆえに、重心を打球フェースよりも後方へ置くほどボールの飛翔の方向性がよくなる。   Another key point of the club head, the overall center of gravity, is one that has a high center of gravity, which is suitable only for strong golfers because the flight trajectory of the hit ball is low, while the center of gravity is low. The struck ball is highly suitable for both weak golfers and beginners because the hit ball flies high. Further, if the center of gravity is too close to the hitting face, the club head is twisted extremely at the time of impact and the balance is lost. Therefore, the direction of the flight of the ball becomes better as the center of gravity is placed behind the hitting ball face.

そして、場合によっては、ゴルファーにとって必要なクラブヘッドの重心も違うので、その要請に応じてクラブヘッド全体の重心の重量を変えることができたらいいと考えられている。   In some cases, the center of gravity of the club head necessary for the golfer is also different, and it is considered that the weight of the center of gravity of the entire club head can be changed according to the request.

本発明は、前記のようなクラブヘッドの設計理論のもとで、ヘッド全体の打球フェースよりも後方寄りの深い重心深度（打球フェースから重心までの距離）と低重心を有し、振動減衰効果が優れたクラブヘッドを提供しようとすることを目的とする。   The present invention, based on the design theory of the club head as described above, has a deep center of gravity depth (distance from the ball striking face to the center of gravity) closer to the rear than the ball striking face of the entire head and a low center of gravity. The aim is to provide an excellent club head.

前記の他に、また、その重心が簡単に変更できるクラブヘッドを提供しようとすることをもう一つの目的とする。   In addition to the above, another object is to provide a club head whose center of gravity can be easily changed.

前記目的を達成するために、本発明は、ボールを打撃するフェースを備えた前面部と、該前面部から後方へ伸びてなった後枠部とを有するクラブヘッドにおいて、前記後枠部の後下側の当たりに窪みが形成され、該窪みに凹陥部のある振動減衰材が充填され、また、該振動減衰材の凹陥部に釣合重りが充填されているクラブヘッドを提供し、特に該釣合重りが簡単に交換できるように構成されたクラブヘッドを提供する。   In order to achieve the above object, the present invention provides a club head having a front surface portion having a face for hitting a ball and a rear frame portion extending rearward from the front surface portion. There is provided a club head in which a depression is formed at the lower side, the depression is filled with a vibration damping material having a depression, and the depression of the vibration damping material is filled with a balance weight. Provided is a club head configured so that the counterweight can be easily replaced.

前記構造によるクラブヘッドは、全体の後下側の当たりに振動減衰材が充填されているとともに、その上に釣合重りが交換可能に充填されているので、振動を減衰させる効果を持つうえ、クラブヘッド全体の深い重心深度と低重心を実現させることができる。   The club head with the above structure is filled with a vibration damping material around the rear lower side of the whole, and the balance weight is exchangeably filled thereon, so that it has an effect of dampening vibrations. Deep center of gravity depth and low center of gravity of the entire club head can be realized.

さらに、前記釣合重りが交換可能に充填されているので、ゴルファーは異なる重量の釣合重りを取り替えることによって、需要に応じてクラブヘッド全体の重心を調整することができる。  Furthermore, since the counterweight is filled in a replaceable manner, the golfer can adjust the center of gravity of the entire club head according to demand by replacing the counterweight with a different weight.

以下に、本発明の好適な実施形態について、添付の図面を参照して説明する。なお、以下の説明には、類似した部材について同一の符号を付与することにする。   Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, the same reference numerals are given to similar members.

図１は、本発明の第１の実施形態にかかるクラブヘッドを斜め下からみた斜視図である。図２は、図１の第１の実施形態にかかるクラブヘッドを側面からみた断面図（打球面を正面とした場合）である。図３は、本発明の第２の実施形態にかかるクラブヘッドを反打球面の方からみた斜視図である。図４は、図３の第２の実施形態にかかるクラブヘッドを側面からみた断面図（打球面を正面とした場合）である。   FIG. 1 is a perspective view of a club head according to a first embodiment of the present invention as seen obliquely from below. FIG. 2 is a cross-sectional view of the club head according to the first embodiment of FIG. 1 as viewed from the side (when the ball striking face is the front). FIG. 3 is a perspective view of a club head according to a second embodiment of the present invention as viewed from the counter-striking spherical surface. FIG. 4 is a cross-sectional view of the club head according to the second embodiment shown in FIG. 3 as viewed from the side (when the ball striking face is the front).

図２及び図４に示すように、本発明のクラブヘッド２は、基本的には、ボールを打撃するフェース２０１を備えた前面部２０（即ち打球面）と、該前面部２０から後方へ伸びてなった後枠部２１とを有する。前記後枠部２１の後下側の当たりに窪み２１６が形成され、該窪み２１６に凹陥部のある振動減衰材２２が充填され、また、該振動減衰材２２の凹陥部に釣合重り２３が充填されている。   As shown in FIGS. 2 and 4, the club head 2 of the present invention basically has a front surface portion 20 (that is, a ball striking surface) provided with a face 201 for hitting a ball, and extends rearward from the front surface portion 20. And a rear frame portion 21. A recess 216 is formed near the rear lower side of the rear frame portion 21, the recess 216 is filled with a vibration damping material 22 having a recess, and a counterweight 23 is provided in the recess of the vibration damping material 22. Filled.

そして、図１と図２に示すように、第１の実施形態はウッドクラブヘッドであり、それにおいて、クラブヘッド２の後枠部２１は、前面部２０の周縁から後方へ伸びて徐々に先細に収束し、前面部２０と合わせて中空体となったものであり、また、前記窪み２１６は、後枠部２１の上下の境界線２１０の下側面に形成されている。   As shown in FIGS. 1 and 2, the first embodiment is a wood club head, in which the rear frame portion 21 of the club head 2 extends backward from the periphery of the front surface portion 20 and gradually tapers. The hollow 216 is formed on the lower surface of the upper and lower boundary lines 210 of the rear frame portion 21.

詳しく説明すると、前面部２０にはほぼ直線となった下周縁２１１があり、後枠部２１は、底面部２１３と背面部２１２とからなっている。該底面部２１３は、前面部２０の前記下周縁２１１から後方へ伸びてなったほぼ平面状なもので、該背面部２１２は、前面部２０の周縁の下周縁２１１以外の部分及び底面部２１３の周縁の下周縁２１１と連接している部分以外の部分から延出して一体に連接してなった。前記窪み２１６は底面部２１３における後側の背面部２１２寄りの所に形成されている。さらに、窪み２１６内の底壁２１４に複数の通孔２１５が開設されている。このように構成されたクラブヘッド２は、全体の重心深度が大きくさせられたうえ、重心高さも低くなった。   More specifically, the front surface portion 20 has a lower peripheral edge 211 that is substantially straight, and the rear frame portion 21 includes a bottom surface portion 213 and a back surface portion 212. The bottom surface portion 213 is substantially planar and extends rearward from the lower peripheral edge 211 of the front surface portion 20, and the rear surface portion 212 is a portion other than the lower peripheral edge 211 of the front surface portion 20 and the bottom surface portion 213. It extended from parts other than the part connected with the lower periphery 211 of the periphery of this, and was connected integrally. The recess 216 is formed in the bottom surface portion 213 near the rear surface portion 212 on the rear side. Further, a plurality of through holes 215 are formed in the bottom wall 214 in the recess 216. The club head 2 configured as described above has an increased depth of the entire center of gravity and a reduced center of gravity.

複数の通孔２１５は窪み２１６内の底壁２１４に開設されているが、それに限られず、窪み２１６内の壁面の他の位置に開設されていても良い。複数の通孔２１５により、ボールを打った瞬間、中空体となった後枠部２１の内部空間にある空気から生じる振動は振動減衰材２２に伝わる。振動減衰材２２は、この振動を吸収するとともに、ボールを打った瞬間にクラブヘッドが受けた衝撃を減衰させることができる。しかも、振動減衰材２２を介して、釣合重り２３の後枠部２１への振動伝達も遮断される。   The plurality of through holes 215 are formed in the bottom wall 214 in the recess 216, but are not limited thereto, and may be provided in other positions on the wall surface in the recess 216. Due to the plurality of through holes 215, the vibration generated from the air in the inner space of the rear frame portion 21 that has become a hollow body is transmitted to the vibration damping material 22 at the moment of hitting the ball. The vibration damping material 22 can absorb this vibration and attenuate the impact received by the club head at the moment of hitting the ball. In addition, vibration transmission to the rear frame portion 21 of the counterweight 23 is also blocked through the vibration damping material 22.

本実施形態において、振動減衰材２２はゴム製の断面コ字形のものであり、釣合重り２３は金属製のプラグ形のものであって振動減衰材２２の断面コ字形の凹陥部に交換可能に充填されている。釣合重り２３は振動減衰材２２の断面コ字形の凹陥部に嵌合などの方式で交換可能に充填されているので、異なる重量の釣合重り２３を取り替えることによって、必要に応じて容易にクラブヘッド２全体の重心を調整することができる。   In this embodiment, the vibration damping material 22 is a rubber U-shaped cross section, and the counterweight 23 is a metal plug type and can be replaced with a U-shaped concave section of the vibration damping material 22. Is filled. Since the counterweight 23 is filled in the U-shaped concave portion of the vibration damping material 22 so as to be exchangeable by fitting or the like, it can be easily changed as needed by replacing the counterweight 23 with a different weight. The center of gravity of the entire club head 2 can be adjusted.

また、図３と図４に示すように、第２の実施形態はアイアンクラブヘッド２であり、該実施形態の第１の実施形態にかかるクラブヘッド２との基本的な異なるところは、クラブヘッド２の後枠部２１は、前面部２０の後面から後方へ突出し、その上部２１Ａが後方へ開口している中空状となり、その下部２１Ｂが突台状となり、即ちクラブヘッド２全体は第１の実施形態にかかるクラブヘッド２のような中空体に形成されていない点にある。それに、窪み２１６は前記下部２１Ｂの背面に形成されている。振動減衰材２２と釣合重り２３との部材に至っては、第１の実施形態にかかるクラブヘッド２と同じである。それにより、この実施形態は、その振動減衰材２２が空気から生じる振動を吸収する効果がない外、他に第１の実施形態にかかるクラブヘッド２とまったく同じである。   Further, as shown in FIGS. 3 and 4, the second embodiment is an iron club head 2, and the fundamental difference between the club head 2 according to the first embodiment of the embodiment is the club head. 2 The rear frame portion 21 protrudes rearward from the rear surface of the front surface portion 20 and has a hollow shape in which an upper portion 21A is opened rearward, and a lower portion 21B thereof is a projecting shape, that is, the entire club head 2 is the first one. The club head 2 according to the embodiment is not formed in a hollow body. In addition, the recess 216 is formed on the back surface of the lower portion 21B. The members of the vibration damping material 22 and the counterweight 23 are the same as those of the club head 2 according to the first embodiment. Thereby, this embodiment is exactly the same as the club head 2 according to the first embodiment except that the vibration damping member 22 has no effect of absorbing vibrations generated from the air.

以上、実施形態に基づいて詳細に説明したが、本発明はこれらの実施形態に限定されない。本発明の特徴と目的の範囲内に種々の変形や変更が可能である。   As mentioned above, although it demonstrated in detail based on embodiment, this invention is not limited to these embodiment. Various modifications and changes can be made within the scope of the features and objects of the present invention.

本発明は、ウッドクラブヘッドであれ、アイアンクラブヘッドであれ、一般のクラブヘッドに適用可能なものであり、深い重心深度と低重心を有し、振動減衰効果も優れているので、初心者からベテランまでのゴルファーにとっては、方向性良く高弾道にボールを打ち易くなって、ゴルフをもっと楽しむことができる。   The present invention can be applied to a general club head, whether it is a wood club head or an iron club head, and has a deep center of gravity depth, a low center of gravity, and an excellent vibration damping effect. For golfers up to this point, it is easier to hit the ball on the high trajectory with better direction and enjoy golf more.
