Description

この発明はパターヘッドに関し、特にヘッドの重さを変化させることなく重心深度を簡単に調整できる一方、ヘッド重心の位置を決定した後には競技中にヘッド重心が衝撃等によって変動しないようにしたパターヘッドに関する。   The present invention relates to a putter head, and more particularly to a putter in which the depth of the center of gravity can be easily adjusted without changing the weight of the head. Regarding the head.

ゴルフ競技において、ドライバーショットがいくら飛んでも、又アイアンショットがいくら正確であっても、グリーン上で例えば3パットも4パットもしていてはスコアメイクは難しい。   In golf competitions, no matter how much the driver shot flies and how accurate the iron shot is, it is difficult to make a score if there are 3 or 4 putts on the green, for example.

通常、ゴルフコースでは1番から18番までの各ホールのグリーン毎に傾斜や芝目等の異なる位置にピンを設定し、多くのプレイヤーが自分の技量に応じてプレイを楽しめるようにしている。   In general, on golf courses, pins are set at different positions such as slopes and grasses for each green of No. 1 to No. 18 so that many players can enjoy playing according to their skills.

ここで、パッティングで大切なことはパターヘッドをいかによいタッチでボールに当てるかどうかである。パッティングのタッチは個々のプレイヤーによって異なるが、一般的に打撃フェイスのスイートスポットの広さや重心深度が密接に関係していることが知られている。   Here, what is important in putting is how to put the putter head on the ball with a good touch. Although the touch of putting varies depending on individual players, it is generally known that the sweet spot size of the hitting face and the depth of the center of gravity are closely related.

従来、ヘッド本体のトウ側及びヒール側を高比重の材料で構成しあるいはトウ側及びヒール側に重錘を設けて、いわゆるトウ・ヒールバランスを実現し、打撃フェイスのスイートスポットを大きくするようにしたパターヘッドが種々提案されている(特許文献1、特許文献2、特許文献3)。   Conventionally, the toe side and heel side of the head body are made of a material with high specific gravity, or weights are provided on the toe side and heel side to realize so-called toe-heel balance, and the sweet spot of the hitting face is increased. Various putter heads have been proposed (Patent Document 1, Patent Document 2, and Patent Document 3).

また、ヘッド本体の背後に重錘を内蔵し、ヘッドの重心深度を深くし、スイングをしやすくして安定したストロークを行えるようにしたパターヘッドも提案されている(特許文献4)。   There has also been proposed a putter head in which a weight is built in the back of the head body, the depth of the center of gravity of the head is increased, and a swing can be performed with ease and a stable stroke (Patent Document 4).

特開2002−191733号公報JP 2002-191733 A 特開2001−062013号公報JP 2001-062013 A 特開平11−104279号公報JP-A-11-104279 特開2004−290565号公報JP 2004-290565 A

しかし、上記特許文献4記載のパターヘッドでは自分に合ったタッチを実現し得る重心深度も個々のプレイヤーによって異なるので、自分に最適なパッティングのタッチがなかなか得られない。その為、個々のプレイヤーがヘッド本体に重錘を取付け取外して重心深度を調整する必要があるが、その調整作業が煩わしい。さらには、重錘を取付け取外すと、ヘッドの重さが変化し、同一の重心深度であってもボールに当てた時にタッチが微妙に異なるという問題もあった。   However, with the putter head described in Patent Document 4, the depth of the center of gravity at which a touch suitable for oneself can be realized differs depending on the individual player, so that it is difficult to obtain an optimum putting touch for oneself. Therefore, it is necessary for each player to adjust the depth of center of gravity by attaching and detaching the weight to the head body, but the adjustment work is troublesome. Furthermore, when the weight is attached and removed, the weight of the head changes, and there is also a problem that the touch is slightly different when hitting the ball even at the same depth of gravity.

本発明はかかる問題点に鑑み、ヘッドの重さを変化させることなく重心深度を簡単に調整できるようにしたパターヘッドを提供することを課題とする。   In view of such problems, it is an object of the present invention to provide a putter head that can easily adjust the depth of the center of gravity without changing the weight of the head.

そこで、本発明に係るパターヘッドは、前面に打撃フェイスが形成される一方、シャフト取付け部が設けられたパターヘッドにおいて、打撃フェイスの背後には重錘取付け部が後方に延びて形成され、該重錘取付け部には重錘がスライド可能に支持され、該重錘は取付けねじの螺進によって上記重錘取付け部の任意の位置に固定される一方、上記重錘は上記取付けねじの螺退によってその固定が解放されて上記重錘取付け部に沿ってスライドされ得るようになっていることを特徴とする。   Therefore, the putter head according to the present invention has a striking face formed on the front surface, and in the putter head provided with the shaft mounting portion, a weight mounting portion is formed to extend rearward behind the striking face, A weight is slidably supported on the weight mounting portion, and the weight is fixed to an arbitrary position of the weight mounting portion by screwing of the mounting screw, while the weight is screwed off of the mounting screw. It is characterized in that the fixed state is released by this and can be slid along the weight attaching portion.

本発明の特徴の1つは重錘を取付けねじの螺進によって重錘取付け部の任意の位置に固定し、取付けねじの螺退によって固定を解放して重錘取付け部に沿って前後にスライドできるようにした点にある。   One of the features of the present invention is that the weight is fixed to an arbitrary position of the weight mounting portion by screwing of the mounting screw, and the fixing is released by screwing of the mounting screw and slides back and forth along the weight mounting portion. It is in the point which made it possible.

これにより、打撃フェイスから後方の任意の距離に重錘を固定することができるので、プレイヤーはパターヘッドを自分に合ったタッチに簡単に調整することができる。   As a result, the weight can be fixed at an arbitrary distance behind the striking face, so that the player can easily adjust the putter head to a touch that suits him / her.

例えば、重錘を打撃フェイスから離れた位置に来るように調整すると、重心深度が深くなる。重心深度の深いパターの場合、ゴルフプレイヤーがグリップを握ってシャフトを自然に垂下させると、パターヘッドはヘッド重心がグリップの鉛直下方に位置した姿勢をとって安定するので、打撃フェイスはヘッド重心よりも前方に位置する。   For example, if the weight is adjusted so as to be located away from the hitting face, the depth of the center of gravity becomes deeper. In the case of a putter with a deep center of gravity, when the golf player grips the grip and naturally hangs the shaft, the putter head is stabilized with the head center of gravity positioned vertically below the grip. Is also located forward.

すると、パターヘッドをスイングし、打撃フェイスがボールに当たる位置に達した瞬間にはパターヘッドは上述の安定姿勢に達しておらず、その後にヘッドの重さによってヘッド重心がグリップの鉛直下方に位置する上述の安定姿勢を経て前方に移動する。これは打撃フェイスをボールに当てた後のフォロースルーの最初の動作がパターヘッドの重さによって行われることを意味し、後はその勢いを利用してフォロースルーを終わらせればよいので、打撃フェイスを目標に正確に指向させた姿勢でフォロースルーを行うことができ、バックスイングからフォロースルーまでを所望の軌跡で安定にスイングできる。   Then, at the moment when the putter head swings and the hitting face reaches the position where it hits the ball, the putter head does not reach the above-mentioned stable posture, and then the head center of gravity is positioned vertically below the grip due to the weight of the head. It moves forward through the above-mentioned stable posture. This means that the first action of the follow-through after hitting the hitting face to the ball is performed by the weight of the putter head, and then the follow-through can be ended using that momentum. The follow-through can be performed with a posture that is accurately directed to the target, and the swing from the back swing to the follow-through can be stably performed with a desired trajectory.

逆に、重錘を打撃フェイスの近くに位置するように調整すると、上述の安定姿勢の直前で打撃フェイスがゴルフボールに当たるので、プレイヤーはスイングの慣性力がそのままゴルフボールに伝わった感触、つまりゴルフボールをダイレクトに打撃したタッチが得られる。   Conversely, if the weight is adjusted so as to be positioned near the hitting face, the hitting face hits the golf ball immediately before the above-mentioned stable posture, so that the player feels that the inertial force of the swing is transmitted to the golf ball as it is, that is, golf Touch that hits the ball directly is obtained.

重心深度とはヘッド重心から打撃フェイスに引いた垂線の長さをいう。また、スイートスポットとはヘッド重心から打撃フェイスに引いた垂線と打撃フェイスとが交差する点(打撃フェイスの中心)から外れた位置でゴルフボールを打撃してもグリップを握る手が痺れないような打撃フェイスにおける領域をいう。   The center of gravity depth refers to the length of the perpendicular drawn from the head center of gravity to the striking face. In addition, the sweet spot means that the hand holding the grip is not disturbed even if the golf ball is hit at a position off the point where the perpendicular line drawn from the center of gravity of the head to the hitting face intersects the hitting face (center of the hitting face) The area in the hitting face.

重錘は取付けねじの螺進退によって重錘取付け部に固定し移動し得るようになっていればよい。例えば、重錘取付け部には長穴を形成し、重錘の長手方向の全部又は一部を二分割構造とし、取付けねじを螺進させて重錘の外径を拡張させ、長穴内面に押し付けて固定するようにすると、取付けねじの螺進退による長穴内面の損傷のおそれを回避できるので、好ましい。   The weight only needs to be fixed to the weight mounting portion by moving the mounting screw back and forth so that the weight can be moved. For example, a long hole is formed in the weight mounting portion, and the weight is entirely or partially divided into two parts, and the outer diameter of the weight is expanded by screwing the mounting screw to It is preferable to fix by pressing because the risk of damage to the inner surface of the long hole due to the advancement and retraction of the mounting screw can be avoided.

即ち、重錘取付け部はヘッド背面から打撃フェイス背後に向けて延び重錘がスライド自在に内蔵される長穴を有し、この重錘は取付けねじの螺進によってその外径が拡張されて長穴内に固定される一方、取付けねじの螺退によって外径が収縮されて固定を解放されるように構成されることができる。   In other words, the weight mounting portion has a long hole that extends from the back of the head toward the back of the striking face and in which the weight is slidably incorporated. The weight of the weight is extended by the screwing of the mounting screw. While being fixed in the hole, the outer diameter is contracted by the screwing of the mounting screw so that the fixing can be released.

また、重錘を螺挿した取付けねじの先端を重錘取付け部に押し付けて固定するようにしてもよい。即ち、重錘取付け部はヘッド背面から打撃フェイス背後に向けて延び重錘がスライド自在に内蔵される長穴を有し、又重錘には取付けねじが螺挿され、この取付けねじの螺進によって取付けねじの先端が重錘から突出し、長穴内面に押しつけられて重錘を長穴内に固定する一方、取付けねじの螺退によって取付けねじの先端が後退し、固定を解放されるように構成されることもできる。   Further, the tip of the mounting screw into which the weight is screwed may be pressed and fixed to the weight mounting portion. In other words, the weight mounting portion has an elongated hole that extends from the back of the head toward the back of the striking face and in which the weight is slidably incorporated, and a mounting screw is screwed into the weight. The tip of the mounting screw protrudes from the weight and is pressed against the inner surface of the elongated hole to fix the weight in the elongated hole, while the distal end of the mounting screw is retracted by releasing the mounting screw to release the fixing. Can also be done.

ゴルフ規則上、パターヘッドについても競技中に重心や重さが変動してはならないことが要求される。そこで、取付けねじが衝撃などによって緩んでも重錘が移動しないように工夫するのが望ましい。   The golf rules require that the center of gravity and weight of the putter head must not change during the competition. Therefore, it is desirable to devise so that the weight does not move even if the mounting screw is loosened by an impact or the like.

そこで、二分割構造の重錘の場合、長穴の内面には複数の凹部を長手方向に並べて形成し、重錘の外面には1又は複数の突起を形成し、取付けねじの螺進によって重錘の外径が拡張されたときに1又は複数の突起が複数のうちの対応する凹部に嵌まり込むように構成するのが好ましい。   Therefore, in the case of a weight having a two-part structure, a plurality of recesses are formed in the longitudinal direction on the inner surface of the elongated hole, and one or more protrusions are formed on the outer surface of the weight, and the weight is increased by screwing the mounting screw. It is preferable that one or a plurality of protrusions fit into the corresponding recesses of the plurality when the outer diameter of the weight is expanded.

また、取付けねじを重錘に螺挿させる方式の場合、長穴の内面には複数の凹部を長手方向に並べて形成し、この複数のいずれか1つの凹部には取付けねじの先端が嵌まり込むように構成するのがよい。   Further, in the case of the method in which the mounting screw is screwed into the weight, a plurality of concave portions are formed in the longitudinal direction on the inner surface of the elongated hole, and the tip of the mounting screw is fitted into any one of the plurality of concave portions. It is better to configure as follows.

この構造の場合、取付けねじの先端部には取付け穴を中心軸線方向に延びて形成し、この取付け穴にはボールをばね部材によって突出方向に付勢して挿入し、ボールが凹部に嵌まり込むように構成すると、競技中の重心の変動をより確実に防止できる。   In the case of this structure, a mounting hole is formed at the tip of the mounting screw so as to extend in the direction of the central axis, and the ball is inserted into the mounting hole by being biased in the protruding direction by a spring member, and the ball is fitted into the recess. If it is configured so that the center of gravity is changed during the competition, it can be more reliably prevented.

重錘取付け部は打撃フェイスに対して垂直な方向に延びるように形成されていれば、例えばヘッド重心を前後に通るように設けてもよく、又トウ側及びヒール側に各々設けるようにしてもよく、さらにはヘッド重心、トウ側及びヒール側の各々に設けるようにしてもよい。即ち、重錘取付け部はヘッドを通常のアドレスポジションをとって置いたときのヘッドの垂直投影平面における打撃フェイスに垂直な方向に延びて形成されるのが重要である。   If the weight attaching portion is formed so as to extend in a direction perpendicular to the striking face, for example, the weight attaching portion may be provided so as to pass back and forth through the center of gravity of the head, or provided on the toe side and the heel side. Alternatively, it may be provided on each of the center of gravity of the head, the toe side, and the heel side. That is, it is important that the weight mounting portion is formed to extend in a direction perpendicular to the striking face on the vertical projection plane of the head when the head is placed at a normal address position.

また、重錘取付け部はヘッドを通常のアドレスポジションをとって置いたときのヘッドの垂直投影平面におけるヘッド重心の位置を通って形成されることができる。この場合、重錘を重錘取付け部に沿ってスライドさせるだけでヘッド重心の位置を調整できるので、自分にピッタリと合ったタッチのパターヘッドが簡単に得られる。   Further, the weight attaching portion can be formed through the position of the center of gravity of the head in the vertical projection plane of the head when the head is placed at the normal address position. In this case, since the position of the center of gravity of the head can be adjusted by simply sliding the weight along the weight mounting portion, it is possible to easily obtain a putter head with a touch that fits perfectly.

さらに、重錘取付け部はヘッドのトウ側及びヒール側の各々に形成されることもできる。このヘッドのトウ側及びヒール側に重錘取付け部を設ける場合、ヘッド重心の位置の調整がヘッド重心の位置に重錘取付け部を設ける場合に比して難しくなるが、トウ側及びヒール側の重錘を適宜調整することによって自分に合ったトウ・ヒールバランスが得られ、一旦自分に合ったヘッド重さに調整できると、その後は重錘の前後位置を調整してヘッド重心の位置を調整するだけで自分に最適な大きさのスイートスポットと自分にピッタリと合ったタッチのパターヘッドが簡単に得られる。   Furthermore, the weight attaching portion can be formed on each of the toe side and the heel side of the head. When the weight attaching portions are provided on the toe side and the heel side of the head, it is difficult to adjust the position of the center of gravity of the head as compared with the case of providing the weight attaching portion at the position of the head center of gravity. By adjusting the weight appropriately, the toe-heel balance that suits you can be obtained, and once you can adjust the head weight that suits you, adjust the position of the center of gravity of the head by adjusting the front and back positions of the weight By simply doing, you can easily obtain a sweet spot that is the best size for you and a putter head that fits perfectly.

重錘取付け部は打撃フェイスの背後から後方に延びて形成され、重錘をスライド可能に支持し得るものであればどのような形状や構造でもよいが、ゴルフ規則上、プレイ中にヘッド重心や重さを調整できるような構造でないことが求められる。   The weight mounting portion is formed to extend rearward from the back of the hitting face, and may have any shape or structure as long as the weight can be slidably supported. It is required that the structure is not capable of adjusting the weight.

例えば、重錘取付け部はヘッド背面から打撃フェイスに向けて延び重錘をスライド自在に内蔵する長穴とし、長穴のヘッド背面の開口から工具を差し込んで取付けねじを螺進退させ、重錘の少なくとも一部の外径を拡張し収縮させるようにしてもよいが、重錘が長穴の奥方になると工具の差し込みが煩わしい。   For example, the weight attachment part extends from the back of the head toward the striking face, and is a long hole that slidably incorporates the weight, inserts a tool through the opening on the back of the head of the long hole, and advances and retracts the attachment screw. Although at least a part of the outer diameter may be expanded and contracted, the insertion of the tool is troublesome when the weight is behind the elongated hole.

そこで、重錘取付け部は上記と同様に、ヘッド背面から打撃フェイス背後に向けて延び重錘がスライド自在に内蔵される長穴とするが、この長穴の上側又は下側には長穴内の重錘よりも小幅でかつ重錘の取付けねじを螺進退させるための工具を長穴内に差し込み得る幅の長溝を長穴に沿って形成するのがよい。   Therefore, the weight mounting portion is a long hole that extends from the back of the head toward the back of the striking face in the same manner as described above, and the weight is slidably incorporated therein. A long groove having a width smaller than that of the weight and capable of inserting a tool for reciprocating the attachment screw of the weight into the elongated hole is preferably formed along the elongated hole.

パターヘッドの材料は特に限定されず、どのような材料を用いてもよい。例えば、アルミニウム系の材料(例えば、アルミニウム、アルミニウム合金)、マグネシウム合金その他の軽金属材料、プラスチック材料あるいは複合材料(例えば、FRP、C・FRP等)、銅系材料(例えば、銅、真鍮その他の銅合金)、鉄系材料(例えば、鉄鋼、ステンレス)、あるいはタングステンで製作することができる。重錘はパターヘッドよりも比重の大きい材料であればよい。   The material of the putter head is not particularly limited, and any material may be used. For example, aluminum-based materials (for example, aluminum, aluminum alloys), magnesium alloys and other light metal materials, plastic materials or composite materials (for example, FRP, C / FRP, etc.), copper-based materials (for example, copper, brass and other copper) Alloys), ferrous materials (eg, steel, stainless steel), or tungsten. The weight may be any material having a specific gravity greater than that of the putter head.

以下、本発明を図面に示す具体例に基づいて詳細に説明する。図1ないし図4は本発明に係るパターヘッドの基本的な考え方を示す。図において、パターヘッド10は例えばアルミニウム系の材料を用いて製作され、パターヘッド10の前部の横幅方向の一端側部分はトウ11、他端側部分はヒール12となっており、又ヘッド10の前面には打撃フェイス13がトウ11からヒール12にわたって形成されている。 Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 4 show the basic concept of a putter head according to the present invention. In the figure, the putter head 10 is manufactured using, for example, an aluminum-based material. One end side portion of the front portion of the putter head 10 in the lateral width direction is a toe 11 and the other end side portion is a heel 12. A striking face 13 is formed from the toe 11 to the heel 12 on the front surface of the lens.

また、パターヘッド10の前部上面にはヒール12近くにシャフト取付け穴(シャフト取付け部)14が形成され、シャフト取付け穴14にはシャフト20の下端が固定され、シャフト20の上端部にはグリップ(図示せず)が設けられている。   A shaft mounting hole (shaft mounting portion) 14 is formed near the heel 12 on the upper surface of the front portion of the putter head 10, and the lower end of the shaft 20 is fixed to the shaft mounting hole 14. (Not shown) is provided.

さらに、パターヘッド10には打撃フェイス13の背後から後方に延びて重錘取付け部15が形成されている。この重錘取付け部15はパターヘッド10を通常のアドレスポジションをとって置いたときのヘッドの垂直投影平面におけるヘッド重心CGhの位置を通って打撃フェイス13に垂直な方向に延びて形成されている。   Further, a weight attaching portion 15 is formed on the putter head 10 so as to extend rearward from the back of the hitting face 13. The weight mounting portion 15 is formed to extend in a direction perpendicular to the striking face 13 through the position of the head center of gravity CGh in the vertical projection plane of the head when the putter head 10 is placed at the normal address position. .

この重錘取付け部15はほぼ横向きの四角形柱状をなし、重錘取付け部15には断面円形の長穴15Aがヘッド背面16から打撃フェイス13に向けて形成され、又重錘取付け部15の上面には長溝15Bが長穴15Aに沿って形成されている。この長溝15Bは後述の重錘17の外径よりも小幅でかつ重錘17の取付けねじ18を操作するための工具19を差し込み得る幅となっている。   The weight mounting portion 15 has a substantially horizontal quadrangular columnar shape, and the weight mounting portion 15 is formed with an elongated hole 15A having a circular cross section from the head back surface 16 toward the striking face 13, and the upper surface of the weight mounting portion 15 A long groove 15B is formed along the long hole 15A. The long groove 15B has a width smaller than an outer diameter of a weight 17 described later and a width capable of inserting a tool 19 for operating a mounting screw 18 of the weight 17.

また、長穴15A内には重錘17がスライド自在に内蔵されている。この重錘17には取付けねじ18が螺挿され、取付けねじ18の先端は重錘17から下方に突出されている。他方、長穴15Aの底面には複数の凹部15Cが相互に適切な間隔、例えば1〜3mmをあけて長手方向に並べて形成され、複数のうちの1つの凹部15Cには重錘17から突き出た取付けねじ18の先端が嵌まり込み、又取付けねじ18の上端面には工具19を連結するための凹部が形成されている。   A weight 17 is slidably incorporated in the elongated hole 15A. A mounting screw 18 is screwed into the weight 17, and the tip of the mounting screw 18 protrudes downward from the weight 17. On the other hand, a plurality of recesses 15C are formed on the bottom surface of the long hole 15A so as to be arranged in the longitudinal direction with an appropriate interval, for example, 1 to 3 mm, and one of the plurality of recesses 15C protrudes from the weight 17. The tip of the mounting screw 18 is fitted, and a recess for connecting the tool 19 is formed on the upper end surface of the mounting screw 18.

パターヘッド10の重心深度を調整する場合、重錘取付け部15の長溝15Bから工具19を差し込み、取付けねじ18の凹部に連結して取付けねじ18を螺退させると、取付けねじ18の先端が長穴15Aの凹部15Cから抜け、重錘18は長穴15Aに沿ってスライド自在となるので、工具19によって重錘18を長穴15A内において前後方向の適切な位置に移動させる。   When adjusting the depth of the center of gravity of the putter head 10, when the tool 19 is inserted from the long groove 15 </ b> B of the weight mounting portion 15 and connected to the recess of the mounting screw 18 and the mounting screw 18 is screwed out, the tip of the mounting screw 18 is long. Since the weight 18 comes out of the recess 15C of the hole 15A and can slide freely along the long hole 15A, the weight 18 is moved by the tool 19 to an appropriate position in the longitudinal direction in the long hole 15A.

その後、取付けねじ18を螺進させて取付けねじ18の先端を重錘17から突出させると、長穴15Aの凹部15Cの1つに嵌まり込み、さらに取付けねじ18を螺進させると、重錘17が長穴15Aの内面に押しつけられて固定されるので、グリップを握ってスイングし、打撃フェイス13をボール30に当ててタッチを確認し、自分にあったタッチとなるまで上述の調整作業を繰り返せばよい。   After that, when the attachment screw 18 is screwed and the tip of the attachment screw 18 protrudes from the weight 17, it fits into one of the recesses 15C of the elongated hole 15A, and when the attachment screw 18 is further screwed, Since 17 is pressed against the inner surface of the long hole 15A and fixed, it swings by grasping the grip, hitting the striking face 13 against the ball 30, confirming the touch, and performing the above-described adjustment work until the touch that suits the user is achieved. Repeat it.

今、重錘18を打撃フェイス13の近くに位置させて固定すると、図4の(a)に示されるように、ヘッド重心CGhは打撃フェイス13に近づく。このような重心深度の浅いパターヘッド10でパッティングすると、打撃フェイス13がボール30に当たった瞬間にはヘッド重心CGhはボール30の重心CGbに接近しているので、プレイヤーはスイングしたパターヘッド10の慣性力がそのままボール30に伝わった感触、つまりダイレクトにボール30を打撃したようなタッチが得られる。   Now, when the weight 18 is positioned and fixed near the hitting face 13, the center of gravity CGh of the head approaches the hitting face 13 as shown in FIG. When putting with the putter head 10 having such a shallow depth of gravity, since the head center of gravity CGh is close to the center of gravity CGb of the ball 30 at the moment when the hitting face 13 hits the ball 30, the player moves the swinging putter head 10. A feeling that the inertial force is transmitted to the ball 30 as it is, that is, a touch that directly hits the ball 30 is obtained.

他方、重錘18を打撃フェイス13から離れた位置に固定すると、図4の(b)に示されるように、ヘッド重心CGhは打撃フェイス13から離れ、重心深度が深くなる。重心深度の深いパターヘッド10でパッティングすると、打撃フェイス13がボール30に当たった瞬間にはヘッド重心CGhはボール30の重心CGbから後方に離れているので、上述のようなボール30をダイレクトに打撃したようなタッチは得られない。   On the other hand, when the weight 18 is fixed at a position away from the striking face 13, as shown in FIG. 4B, the head center of gravity CGh is separated from the striking face 13, and the center of gravity depth is deepened. When putting with the putter head 10 having a deep center of gravity, since the head center of gravity CGh is separated from the center of gravity CGb of the ball 30 at the moment when the hitting face 13 hits the ball 30, the ball 30 as described above is directly hit. You can't get a touch like that.

通常、ゴルフプレイヤーがグリップを握ってシャフトを自然に垂下させると、パターヘッド10はヘッド重心CGhがグリップの鉛直下方に位置した姿勢をとって安定する。重心深度の深いパターヘッド10の場合には打撃フェイス13がボール30に当たった瞬間にはパターヘッド10は上述の安定姿勢に達しておらず、打撃フェイス13がボール30に当たった後、パターヘッド10は自分の重さによってヘッド重心CGhがグリップの鉛直下方の安定姿勢に達する。つまり、フォロースルーの最初の動作がパターヘッド10の重さによって行われ、後はその勢いを利用してフォロースルーを終わらせればよいので、打撃フェイス13を目標に正確に指向させた姿勢でフォロースルーを行うことができ、バックスイングからフォロースルーまでを所望の軌跡で安定にスイングできる。   Normally, when the golf player grips the grip and hangs down the shaft naturally, the putter head 10 is stabilized in a posture in which the center of gravity CGh is positioned vertically below the grip. In the case of the putter head 10 having a deep center of gravity depth, the putter head 10 does not reach the above-mentioned stable posture at the moment when the hitting face 13 hits the ball 30, and after the hitting face 13 hits the ball 30, the putter head 10, the center of gravity CGh of the head reaches a stable posture vertically below the grip by its own weight. That is, the first motion of the follow-through is performed by the weight of the putter head 10, and after that, the follow-through should be terminated using the momentum. Therefore, the follow-up is performed with the striking face 13 oriented accurately to the target. Through can be performed, and it is possible to stably swing from a backswing to a follow-through with a desired trajectory.

また、競技中に打撃による衝撃などによって取付けねじ18が緩むと、重錘17が移動してしまうことが懸念されるが、本例では取付けねじ18の先端が長穴15の凹部15Cに嵌まり込んでいるので、取付けねじ18が緩んでもその先端が凹部15C内に入り込んでいる限りは重錘18が位置を変えることがない。また、プレイヤーは取付けねじ18が緩むと、パッティングしたときのパターの感覚が微妙に異なることが分かるので、工具19で取付けねじ18を螺進させて締めつければ元の固定状態に戻すことができる。   In addition, there is a concern that the weight 17 may move if the mounting screw 18 is loosened due to impact or the like due to impact during the competition, but in this example, the tip of the mounting screw 18 fits into the recess 15C of the elongated hole 15. Therefore, even if the mounting screw 18 is loosened, the weight 18 does not change its position as long as the tip of the mounting screw 18 enters the recess 15C. In addition, since the player knows that the feeling of the putter is slightly different when the mounting screw 18 is loosened, if the mounting screw 18 is screwed and tightened with the tool 19, it can be returned to the original fixed state. .

また、図5は本発明に係るパターヘッドの好ましい実施形態を示し、図において図1ないし図4と同一符号は同一又は相当部分を示す。本例では取付けねじ18の先端部に取付け穴18Aを中心軸線方向に延びて形成し、この取付け穴18A内にボール18Bを挿入してコイルばね18Cによって突出方向に付勢して取付けばね18を構成している。 FIG. 5 shows a preferred embodiment of a putter head according to the present invention, in which the same reference numerals as in FIGS. 1 to 4 denote the same or corresponding parts. In this example, a mounting hole 18A is formed at the tip of the mounting screw 18 so as to extend in the central axis direction, and a ball 18B is inserted into the mounting hole 18A and urged in a protruding direction by a coil spring 18C. It is composed.

本例では取付けねじ18の先端にはボール18Bが突出されるとともに、突出方向に付勢され、長穴15Aの複数のうちの1つの凹部15C内に嵌まり込んでおり、取付けねじ17が多少大きく緩んでもボール18Bが凹部15Cから抜け難く、競技中の重心の変動をより確実に防止できる。   In this example, the ball 18B protrudes from the tip of the mounting screw 18 and is urged in the protruding direction, and is fitted in one of the plurality of recesses 15C of the elongated hole 15A. Even if the ball 18B is loosened greatly, it is difficult for the ball 18B to come out of the recess 15C, and the change in the center of gravity during the game can be prevented more reliably.

図6及び図7は第2の実施形態を示し、図において図1ないし図4と同一符号は同一又は相当部分を示す。本例では重錘17は上下に2分割され、上方部分17Aには取付けねじ18が螺挿され、取付けねじ18の先端は重錘17の下側部分17Bに回転自在に螺合され、取付けねじ18の上端面には工具19を連結するための凹部が形成され、又重錘17の下側部分17Bの底面には突起17Cが形成され、この突起17Cは長穴15Aの複数のうちの1つの凹部15Cに嵌まり込んでいる。 6 and 7 show a second embodiment, in which the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. In this example, the weight 17 is vertically divided into two parts, a mounting screw 18 is screwed into the upper portion 17A, and the tip of the mounting screw 18 is rotatably screwed into the lower portion 17B of the weight 17 so as to be mounted. A recess for connecting the tool 19 is formed on the upper end surface of 18, and a protrusion 17 C is formed on the bottom surface of the lower portion 17 B of the weight 17, and this protrusion 17 C is one of a plurality of elongated holes 15 A. It fits into the two recesses 15C.

取付けねじ18が工具19によって螺進されると、上側部分17Aと下側部分17Bとが相互に離間されることによって重錘17の外径が拡張され、重錘17は長穴15Aの内面に押し付けられて固定され、同時に重錘17の下側部分17Bの突起17Cが長穴15Aの凹部15Cに嵌まり込み、重錘17が長穴15A内に固定される。   When the attachment screw 18 is screwed by the tool 19, the outer diameter of the weight 17 is expanded by separating the upper portion 17A and the lower portion 17B from each other, and the weight 17 is formed on the inner surface of the elongated hole 15A. At the same time, the protrusion 17C of the lower portion 17B of the weight 17 fits into the recess 15C of the elongated hole 15A, and the weight 17 is fixed in the elongated hole 15A.

取付けねじ18を工具19によって螺退させると、重錘17の上側部分17Aと下側部分17Bとが相互に接近されて長穴15A内面への押し付けが解除されるとともに、重錘17の下側部分17Bの突起17Cが長穴15Aの凹部15Cから抜け出し、重錘18は長穴15Aに沿ってスライドできるようになる。   When the mounting screw 18 is screwed out by the tool 19, the upper portion 17A and the lower portion 17B of the weight 17 are brought close to each other, the pressing to the inner surface of the elongated hole 15A is released, and the lower side of the weight 17 The protrusion 17C of the portion 17B comes out of the recess 15C of the elongated hole 15A, and the weight 18 can slide along the elongated hole 15A.

なお、上記の例では重錘取付け部15を1つだけ形成するようにしたが、トウ11側及びヒール12側のそれぞれに設けるようにしてもよい。また、上記の例では重錘取付け部15に長溝15Bを形成したが、長溝15Bは必ずしも形成する必要はない。この場合にはヘッド背面16の開口から取付けねじ18を調整できるようにする必要がある。   In the above example, only one weight attaching portion 15 is formed, but it may be provided on each of the toe 11 side and the heel 12 side. In the above example, the long groove 15B is formed in the weight attaching portion 15, but the long groove 15B is not necessarily formed. In this case, it is necessary to be able to adjust the mounting screw 18 from the opening of the head back surface 16.

さらに、上記の例では取付けねじ18の螺進退によって重錘17の1つの突起17Cを長穴15Aの凹部15Cに嵌まり込ませるようにしたが、重錘18に複数の突起17Cを形成して複数の凹部15Cに嵌まり込ませるようにしてもよい。また、取付けねじ18の螺進退によって取付けねじ18の先端、取付けねじ18のボール18B及び重錘17の突起17Cを長穴15Aの凹部15Cに嵌まり込ませるようにしたが、取付けねじ18の螺進退のみによって重錘18を確実に固定できる場合には凹部18Cは必ずしも形成する必要はない。   Furthermore, in the above example, one protrusion 17C of the weight 17 is fitted into the recess 15C of the elongated hole 15A by the screwing back and forth of the mounting screw 18, but a plurality of protrusions 17C are formed on the weight 18 You may make it fit in the some recessed part 15C. In addition, the tip of the mounting screw 18, the ball 18B of the mounting screw 18 and the projection 17C of the weight 17 are fitted into the recess 15C of the elongated hole 15A by screwing back and forth of the mounting screw 18. In the case where the weight 18 can be reliably fixed only by advancing and retreating, the recess 18C does not necessarily have to be formed.
