錘部材の位置を変更すると、ゴルフクラブヘッドの重心位置が変化する。重心位置が変わるとゴルフクラブヘッドの特性が変わり、例えば、打球の弾道の高低や左右の方向性、操作性、ボールのつかまり具合等が変化する。ゴルファは自身の好みに応じて、錘部材の位置を変更することができる。   When the position of the weight member is changed, the position of the center of gravity of the golf club head changes. When the position of the center of gravity changes, the characteristics of the golf club head change. For example, the height of the trajectory of the hit ball, the direction of the right and left, the operability, and how the ball is held are changed. The golfer can change the position of the weight member according to his / her preference.

しかし、錘部材の位置を変更すると、ゴルフクラブヘッドの複数の特性が同時に変化してしまう場合がある。ゴルファによっては、ボールのつかまり具合は現状のままで、ゴルフクラブヘッドの他の特性を変化させたい場合がある。   However, when the position of the weight member is changed, a plurality of characteristics of the golf club head may change simultaneously. Some golfers may want to change other characteristics of the golf club head while maintaining the ball grip.

本発明の目的は、錘部材の位置が変更可能なゴルフクラブヘッドにおいて、錘部材の位置の変更によって、ボールのつかまり具合の変化はできるだけ小さくしながら、ゴルフクラブヘッドの他の特性を変更可能なゴルフクラブヘッドを提供することにある。   It is an object of the present invention to change other characteristics of a golf club head in a golf club head in which the position of the weight member can be changed by changing the position of the weight member while minimizing the change in the degree of ball holding. It is to provide a golf club head.

本発明によれば、ヘッド本体と、前記ヘッド本体に取付けられる錘部材と、前記錘部材を、前記ヘッド本体の複数の取付位置のいずれかに固定する固定手段と、を備えたゴルフクラブヘッドにおいて、前記複数の取付位置が、前記錘部材が取付けられていない状態での前記ヘッド本体の重心位置と、前記ゴルフクラブヘッドに装着されるシャフトの軸線と、を含む面上に位置していることを特徴とするゴルフクラブヘッドが提供される。   According to the present invention, in a golf club head comprising: a head main body; a weight member attached to the head main body; and a fixing means for fixing the weight member to any one of a plurality of attachment positions of the head main body. The plurality of attachment positions are located on a plane including a center of gravity position of the head body in a state where the weight member is not attached and an axis of a shaft attached to the golf club head. A golf club head is provided.

本発明によれば、錘部材の位置が変更可能なゴルフクラブヘッドにおいて、錘部材の位置の変更によって、ボールのつかまり具合の変化はできるだけ小さくしながら、ゴルフクラブヘッドの他の特性を変更可能なゴルフクラブヘッドを提供することができる。   According to the present invention, in the golf club head in which the position of the weight member can be changed, other characteristics of the golf club head can be changed by changing the position of the weight member while minimizing the change in the degree of the ball holding. A golf club head can be provided.

＜第１実施形態＞
図１は、本発明の一実施形態に係るゴルフクラブヘッドＡの斜視図であり、ソール部１３を透視して表した図である。 <First Embodiment>
FIG. 1 is a perspective view of a golf club head A according to an embodiment of the present invention, and is a view seen through a sole portion 13.

ゴルフクラブヘッドＡは、ヘッド本体１０と、錘部材２０と、を備える。ヘッド本体１０は、中空体をなしており、その周壁が、ゴルフボールの打撃面を形成するフェース部１１と、ゴルフクラブヘッドＡの上面をなすクラウン部１２と、ゴルフクラブヘッドＡの底面をなすソール部１３と、ゴルフクラブヘッドＡのトウ側、ヒール側及びバック側の側面をなすサイド部１４と、を構成している。また、ヘッド本体１０には、シャフトが取り付けられるホゼル部１５が設けられている。   The golf club head A includes a head body 10 and a weight member 20. The head body 10 has a hollow body, and its peripheral wall forms a face portion 11 that forms a striking surface of a golf ball, a crown portion 12 that forms the top surface of the golf club head A, and a bottom surface of the golf club head A. The sole portion 13 and the side portion 14 forming the side surfaces of the toe side, the heel side, and the back side of the golf club head A are configured. The head body 10 is provided with a hosel portion 15 to which a shaft is attached.

ゴルフクラブヘッドＡはドライバ用のゴルフクラブヘッドであるが、本発明はドライバ以外のフェアウエイウッド等も含むウッド型のゴルフクラブヘッド、ユーティリティ型（ハイブリッド型）のゴルフクラブヘッド、その他の中空のゴルフクラブヘッドに適用可能である。また、ヘッド本体１０は、本実施形態の場合、中空体であるが、中実のものであってもよい。   The golf club head A is a golf club head for a driver, but the present invention is a wood type golf club head including a fairway wood other than the driver, a utility type (hybrid type) golf club head, and other hollow golf club heads. It is applicable to. The head body 10 is a hollow body in the present embodiment, but may be a solid body.

ヘッド本体１０は、複数のパーツを接合して組み立てることができる。例えば、フェース部１１と、その他の部分と、をそれぞれ別部材で作成し、これらを接合してヘッド本体１０を作成することができる。また、フェース部１１と、ソール部１３と、その他の部分と、をそれぞれ別部材で作成し、これらを接合してヘッド本体１０を作成することができる。ヘッド本体１０は、例えば金属材料から作成することができ、そのような金属材料としては、チタン系金属材料やステンレス鋼が挙げられる。ヘッド本体１０は、異なる素材から作成することもでき、例えば、金属材料と、炭素繊維材料と、から作成することもできる。炭素繊維材料としては、炭素繊維強化樹脂（ＣＦＲＰ）が挙げられる。   The head body 10 can be assembled by joining a plurality of parts. For example, the head body 10 can be formed by creating the face part 11 and other parts by separate members and joining them together. Further, the head body 10 can be formed by creating the face part 11, the sole part 13 and other parts by separate members and joining them together. The head main body 10 can be made of, for example, a metal material, and examples of such a metal material include a titanium-based metal material and stainless steel. The head body 10 can be made from different materials, for example, from a metal material and a carbon fiber material. Examples of the carbon fiber material include carbon fiber reinforced resin (CFRP).

ソール部１３には、錘部材２０の取付位置を規定する複数の取付部１３１ａ乃至１３１ｄが形成されている。本実施形態の場合、４つの取付部１３１ａ乃至１３１ｄを設けているが、その数は４つに限られない。ゴルフクラブヘッドＡのユーザは、いずれかの取付部１３１ａ乃至１３１ｄに錘部材２０を取り付けることができる。図２は図１の線Ｘ−Ｘに沿うソール部１３の断面図である。   A plurality of attachment portions 131 a to 131 d that define attachment positions of the weight member 20 are formed on the sole portion 13. In the case of the present embodiment, the four attachment portions 131a to 131d are provided, but the number is not limited to four. The user of the golf club head A can attach the weight member 20 to any of the attachment portions 131a to 131d. FIG. 2 is a cross-sectional view of the sole portion 13 taken along line XX in FIG.

各取付部１３１ａ乃至１３１ｄは、雌ネジ孔ＳＣ１を有する筒状をなしている。錘部材２０は、軸状の雄ネジ部ＳＣ２を有しており、雌ネジ孔ＳＣ１と雄ネジ部ＳＣ２とを互いに螺着することで、錘部材２０をヘッド本体１０に固定することができる。   Each attachment part 131a thru | or 131d has comprised the cylindrical shape which has female screw hole SC1. The weight member 20 has an axial male screw portion SC2, and the weight member 20 can be fixed to the head body 10 by screwing the female screw hole SC1 and the male screw portion SC2 together.

ワッシャ３０は、錘部材２０とソール部１３との間に介挿される樹脂部材である。ワッシャ３０は、雌ネジ孔ＳＣ１と雄ネジ部ＳＣ２との螺合の緩み止めとなり、一旦固定した錘部材２０が容易に脱落しないようにしている。ワッシャ３０は、錘部材２０に一体的に設けてもよい。例えば、錘部材２０に予め固着しておいてもよい。また、錘部材２０の表面を樹脂材料で被覆してもよい。   The washer 30 is a resin member interposed between the weight member 20 and the sole portion 13. The washer 30 serves to prevent loosening of the screwing between the female screw hole SC1 and the male screw portion SC2, and prevents the weight member 20 once fixed from easily falling off. The washer 30 may be provided integrally with the weight member 20. For example, it may be fixed to the weight member 20 in advance. Further, the surface of the weight member 20 may be covered with a resin material.

図２に示すように、取付部１３１ａ乃至１３１ｄのうち、錘部材２０を取り付けない取付部については、キャップ４０を取り付けて雌ネジ孔ＳＣ１を閉鎖することができる。これにより、雌ネジ孔ＳＣ１を通してヘッド本体１０内にごみ等が侵入することを防止できる。キャップ４０は、例えば、樹脂材料からなり、雌ネジ孔ＳＣ１に対して取り外し可能に嵌入される。雌ネジ孔ＳＣ１を通してヘッド本体１０内にごみ等が侵入することを防止するため、キャップ４０に代えて、雌ネジ孔ＳＣ１の上端が閉鎖された構成としてもよい。   As shown in FIG. 2, among the attachment portions 131a to 131d, for the attachment portion to which the weight member 20 is not attached, the cap 40 can be attached to close the female screw hole SC1. Thereby, it is possible to prevent dust and the like from entering the head main body 10 through the female screw hole SC1. The cap 40 is made of, for example, a resin material and is detachably inserted into the female screw hole SC1. In order to prevent dust and the like from entering the head main body 10 through the female screw hole SC1, the upper end of the female screw hole SC1 may be closed instead of the cap 40.

また、キャップ４０は、錘部材２０と同様の形状に形成する一方、材料の選択によって、重心位置の変化に実質的に影響を与えない程度の重さのものとし、雌ネジ孔ＳＣ１と螺合するものとしてもよい。   The cap 40 is formed in the same shape as the weight member 20, and has a weight that does not substantially affect the change in the center of gravity by the selection of the material, and is screwed into the female screw hole SC1. It is good also as what to do.

錘部材２０は、例えば、金属材料から作成することができる。そのような金属材料としては、例えば、タングステン、タングステン合金、アルミ、アルミ合金、マグネシウム、マグネシウム合金を挙げられる。また、錘部材２０は、例えば、粘弾性材料に金属粉を混入したものでもよく、この場合、インパクト時のゴルフクラブヘッドＡの制振効果を向上することができる。そのような粘弾性材料としては、例えば、ＮＢＲ（アクリロニトリルブタジエンゴム）が挙げられる。   The weight member 20 can be made of a metal material, for example. Examples of such a metal material include tungsten, a tungsten alloy, aluminum, an aluminum alloy, magnesium, and a magnesium alloy. Further, the weight member 20 may be, for example, a viscoelastic material mixed with metal powder. In this case, the vibration damping effect of the golf club head A at the time of impact can be improved. An example of such a viscoelastic material is NBR (acrylonitrile butadiene rubber).

次に、取付部１３１ａ乃至１３１ｄの位置について図１及び図３を参照して説明する。図３は重心角θの説明図であり、ゴルフクラブヘッドＡを用いたゴルフクラブのシャフトを、その軸線回りに回転可能にして水平に支持した状態において、ゴルフクラブヘッドＡをソール部１３側から見た図である。図３において、矢印Ｄｈは水平方向を、矢印Ｄｖは鉛直方向を示す。   Next, the positions of the attachment portions 131a to 131d will be described with reference to FIGS. FIG. 3 is an explanatory view of the barycentric angle θ, and the golf club head A is viewed from the sole portion 13 side in a state where the shaft of the golf club using the golf club head A is rotatably supported around its axis. FIG. In FIG. 3, the arrow Dh indicates the horizontal direction, and the arrow Dv indicates the vertical direction.

図１及び図３において、重心位置ＣＧは、錘部材２０が取り付けられていない状態でのヘッド本体１０の重心位置である。面Ｓは、ヘッド本体１０の重心位置ＣＧと、ゴルフクラブヘッドＡに装着されるシャフト（不図示）の軸線Ｌ１と、を含む仮想平面である。シャフトはホゼル部１５に装着されることから、軸線Ｌ１はホゼル部１５の軸線と実質的に同じである。取付部１３１ａ乃至１３１ｄは面Ｓ上に位置しており、特に本実施形態では取付部１３１ａ乃至１３１ｄは面Ｓに含まれる直線Ｌ０上に位置している。   1 and 3, the gravity center position CG is the gravity center position of the head body 10 in a state where the weight member 20 is not attached. The surface S is a virtual plane including the center of gravity position CG of the head body 10 and the axis L1 of a shaft (not shown) attached to the golf club head A. Since the shaft is attached to the hosel portion 15, the axis L <b> 1 is substantially the same as the axis of the hosel portion 15. The attachment portions 131a to 131d are located on the surface S. In particular, in this embodiment, the attachment portions 131a to 131d are located on the straight line L0 included in the surface S.

次に、取付部１３１ａ乃至１３１ｄを面Ｓ上に配置したことによる効果について説明する。いずれかの取付部１３１ａ乃至１３１ｄに錘部材２０を固定すると、それにより、ゴルフクラブヘッドＡの重心位置及び重心深さが変化する。ここで、重心深さはゴルフクラブヘッドの重心位置からフェース部への垂線の長さである。なお、フェース部１１が平面でなく、弧状面をなしている場合は、フェースセンタに接する仮想平面を基準とする。   Next, an effect obtained by arranging the attachment portions 131a to 131d on the surface S will be described. When the weight member 20 is fixed to any of the attachment portions 131a to 131d, the center of gravity position and the center of gravity depth of the golf club head A change accordingly. Here, the depth of the center of gravity is the length of a perpendicular line from the position of the center of gravity of the golf club head to the face portion. When the face portion 11 is not a flat surface but an arcuate surface, a virtual plane in contact with the face center is used as a reference.

例えば、取付部１３１ａに錘部材２０を取り付けると、ゴルフクラブヘッドＡの重心位置は、ヘッド本体１０の重心位置ＣＧよりもヒール側に移動する。このため、ゴルフクラブヘッドＡの重心距離は相対的に短くなり、ゴルフクラブヘッドＡの操作性が良くなる。また、ゴルフクラブヘッドＡの重心位置が相対的にヒール側にあると、打球は相対的にフックし易くなるが、後述するように重心角はほとんど変わらないため、ボールが極端につかまることは避けられる。したがって、取付部１３１ａに錘部材２０を取り付けると、操作性が良く、ドロー系の弾道が打ち易いクラブとなる。   For example, when the weight member 20 is attached to the attachment portion 131a, the gravity center position of the golf club head A moves to the heel side relative to the gravity center position CG of the head body 10. For this reason, the center-of-gravity distance of the golf club head A is relatively short, and the operability of the golf club head A is improved. Further, when the center of gravity of the golf club head A is relatively on the heel side, the hit ball is relatively easy to hook, but the center of gravity angle hardly changes as will be described later. It is done. Therefore, when the weight member 20 is attached to the attachment portion 131a, the operability is good and the club is easy to hit a draw type trajectory.

取付部１３１ｄに錘部材２０を取り付けると、ゴルフクラブヘッドＡの重心位置は、ヘッド本体１０の重心位置ＣＧよりもトウ側に移動する。このため、ゴルフクラブヘッドＡの重心距離は相対的に長くなり、ゴルフクラブヘッドＡの操作性としては、ゴルファがヘッドの重みを感じ易く、ゴルファの手先の動きがゴルフクラブヘッドＡの挙動に影響しにくくなる。また、ゴルフクラブヘッドＡの重心位置が相対的にトウ側にあると、打球は相対的にスライスし易くなるが、後述するように重心角は変わらないため、ボールのつかまりが極端に悪くなることが避けられる。したがって、取付部１３１ｄに錘部材２０を取り付けると、ゴルフクラブヘッドＡが、ゴルファの操作に鈍感な挙動を示す傾向になり、小細工することなく、フェード系の弾道を打ち易いクラブとなる。 When the weight member 20 is attached to the attachment portion 131d, the gravity center position of the golf club head A moves to the toe side relative to the gravity center position CG of the head body 10. For this reason, the center-of-gravity distance of the golf club head A is relatively long, and the operability of the golf club head A is that the golfer can easily feel the weight of the head, and the movement of the golfer's hand affects the behavior of the golf club head A. It becomes difficult to do. Further, when the center of gravity of the golf club head A is relatively toe side, but the hitting is likely to relatively slice, since unchanged centroid angle as will be described later, caught becomes extremely poor ball Can be avoided. Therefore, when the weight member 20 is attached to the attachment portion 131d, the golf club head A tends to exhibit insensitive behavior to the operation of the golfer, and the club becomes easy to hit a fade-type trajectory without being crafted.

このように本実施形態では、錘部材２０を固定する取付部１３１ａ乃至１３１ｄを選択することにより、ゴルフクラブヘッドＡの特性を変化させることができる。   Thus, in this embodiment, the characteristics of the golf club head A can be changed by selecting the attachment portions 131a to 131d that fix the weight member 20.

一方、取付部１３１ａ乃至１３１ｄは面Ｓ上に位置しているため、図２から理解されるように、どの取付部１３１ａ乃至１３１ｄに錘部材２０を取付けたとしても、重心角θはほとんど変化しない。重心角θは、軸線Ｌ１を通る鉛直面（図２における面Ｓ）とフェース部１１とがなす角度である。重心角θは、主として、インパクト時のボールのつかまり具合に影響し、重心角θが大きいほど相対的にボールがつかまり易く、重心角θが小さいほど相対的にボールのつかまりが悪くなる。   On the other hand, since the attachment portions 131a to 131d are located on the surface S, as can be understood from FIG. 2, the gravity center angle θ hardly changes even if the weight member 20 is attached to any of the attachment portions 131a to 131d. . The center-of-gravity angle θ is an angle formed by a vertical plane (surface S in FIG. 2) passing through the axis L1 and the face portion 11. The center-of-gravity angle θ mainly affects how the ball is gripped at the time of impact. The larger the center-of-gravity angle θ, the easier it is to grip the ball, and the smaller the center-of-gravity angle θ, the worse the grip of the ball.

このように本実施形態では、錘部材２０の取り付け位置によって、インパクト時のボールのつかまり具合の変化はできるだけ小さくしながら、ゴルフクラブヘッドＡの他の特性を変更することができる。   As described above, in the present embodiment, the other characteristics of the golf club head A can be changed depending on the attachment position of the weight member 20 while minimizing the change in the degree of ball holding at the time of impact.

なお、本実施形態では、錘部材２０を１つとしたが、重さの異なる複数の錘部材２０のいずれかを選択的にヘッド本体１０に固定するようにしてもよい。これにより、ゴルフクラブヘッドＡの重心位置及び重心深さの選択範囲を増やすことができると共に、選択肢も増やすことができる。この場合、２以上の錘部材２０を同時にヘッド本体１０に固定してもよい。   In the present embodiment, one weight member 20 is used. However, any of a plurality of weight members 20 having different weights may be selectively fixed to the head body 10. Thereby, the selection range of the gravity center position and the gravity center depth of the golf club head A can be increased, and options can be increased. In this case, two or more weight members 20 may be simultaneously fixed to the head body 10.

また、錘部材２０を固定する取付部１３１ａ乃至１３１ｄの相違によるゴルフクラブヘッドＡの重心深さの変化量、例えば、取付部１３１ａに錘部材２０を取り付けた場合と、取付部１３１ｄに錘部材２０を取り付けた場合と、の重心深さの差が３ｍｍ以上であることが好ましい。重心深さの差が３ｍｍ以上であれば、重心位置の変化によるゴルフクラブヘッドの特性の変化を、ゴルファがより明確に感じることができる。   Further, the amount of change in the depth of the center of gravity of the golf club head A due to the difference between the attachment portions 131a to 131d for fixing the weight member 20, for example, when the weight member 20 is attached to the attachment portion 131a and when the weight member 20 is attached to the attachment portion 131d. It is preferable that the difference in depth of the center of gravity is 3 mm or more. If the difference in the center of gravity depth is 3 mm or more, the golfer can more clearly feel the change in the characteristics of the golf club head due to the change in the position of the center of gravity.

＜第２実施形態＞
図４は、取付部１３１ａ乃至１３１ｄの他の構成例を示す断面図であり、図１の線Ｘ−Ｘに沿うソール部１３の断面図に相当する。以下、上記第１実施形態のゴルフクラブヘッドＡと同じ構成については同じ符号を付して説明を割愛し、異なる構成についてのみ説明する。 Second Embodiment
FIG. 4 is a cross-sectional view illustrating another configuration example of the attachment portions 131a to 131d, and corresponds to a cross-sectional view of the sole portion 13 along the line XX in FIG. Hereinafter, the same components as those of the golf club head A according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Only different components will be described.

本実施形態の場合、各取付部１３１ａ乃至１３１ｄに、錘部材２０を収容する凹部１３２ａ乃至１３２ｄが設けられている。凹部１３２ａ乃至１３２ｄの深さは、ヘッド本体１０に錘部材２０を固定した状態で、錘部材２０の最下部が、ソール部１３の最下部よりも上方に位置するように設定されている。   In the case of the present embodiment, the mounting portions 131a to 131d are provided with recesses 132a to 132d for accommodating the weight member 20. The depths of the recesses 132 a to 132 d are set so that the lowermost part of the weight member 20 is positioned higher than the lowermost part of the sole part 13 in a state where the weight member 20 is fixed to the head body 10.

このため、図４に示すように、錘部材２０がソール部１３から突出せず、打撃時に錘部材２０が地面に引っかかることを防止できる。   For this reason, as shown in FIG. 4, the weight member 20 does not protrude from the sole portion 13, and the weight member 20 can be prevented from being caught on the ground at the time of impact.

＜第３実施形態＞
図５は、取付部１３１ａ乃至１３１ｄ及び錘部材２０の他の構成例を示す断面図であり、図１の線Ｘ−Ｘに沿うソール部１３の断面図に相当する。以下、上記第１実施形態のゴルフクラブヘッドＡと同じ構成については同じ符号を付して説明を割愛し、異なる構成についてのみ説明する。 <Third Embodiment>
