Abstract
Description
本発明は、ゴルファーの体形、技量、あるいは好みに応じて、ライ角、フェイス角、およびロフト角の少なくとも一つを容易に調整することができるゴルフクラブに関する。 The present invention relates to a golf club that can easily adjust at least one of a lie angle, a face angle, and a loft angle according to a golfer's body shape, skill, or preference.
ドライバーやフェアウェイウッドと称されるウッドは、シャフトとヘッドのソールとの間の角度であるライ角、シャフトの中心線に対するヘッドのフェース面の傾きであるロフト角、およびフェース面とシャフトの中心線との間の角度であるフェース角が、一般に一つの角度に設定されている。
一方、アドレス状態においてゴルファーがグリップする位置は、当該ゴルファーの身長や腕の長さなどの体形、あるいはゴルファーの技量向上によって左右されるため、例えば上記ライ角を体形や技量の向上に応じて変更できるよう調整したくなる場合が往々にして生じる。
Wood called a driver or fairway wood is a lie angle that is the angle between the shaft and the sole of the head, a loft angle that is the inclination of the face of the head relative to the centerline of the shaft, and the centerline of the face and shaft The face angle, which is the angle between the two, is generally set to one angle.
On the other hand, the position where the golfer grips in the address state depends on the body shape such as the height and arm length of the golfer or the improvement of the skill of the golfer. For example, the lie angle is changed according to the improvement of the body shape or the skill It often happens that you want to be able to make adjustments.
そこで、ライ角、ロフト角、フェース角を調整可能としたゴルフクラブとして、シャフトの中心軸に対して約3度傾斜可能なインサートを当該シャフトの先端に嵌合し、且つ係るシャフトとインサートとをヘッドの内部ホーゼルに挿入して固定するゴルフクラブ調整デバイスが提案されている(例えば、特許文献1参照)。
また、ヘッドのヒール側に設けたシャフト角度調整ケース内にシャフトの先端部を挿入し、当該シャフトと上記ケースとの間に接着剤を充填し且つゴム製の移動阻止体を収容した状態で、上記シャフトを固定する角度調整可能ゴルフクラブも提案されている(例えば、特許文献2参照)。上記移動阻止体には、ライ角度調節片とフェイス角度調節片とが形成されている。
Therefore, as a golf club in which the lie angle, loft angle, and face angle can be adjusted, an insert that can be inclined about 3 degrees with respect to the central axis of the shaft is fitted to the tip of the shaft, and the shaft and the insert are A golf club adjusting device that is inserted into and fixed to an internal hosel of a head has been proposed (see, for example, Patent Document 1).
Also, in the state where the tip of the shaft is inserted into the shaft angle adjustment case provided on the heel side of the head, the adhesive is filled between the shaft and the case, and the rubber movement blocking body is accommodated, An angle adjustable golf club for fixing the shaft has also been proposed (see, for example, Patent Document 2). A lie angle adjusting piece and a face angle adjusting piece are formed on the movement blocking body.
しかしながら、特許文献1,2に開示されたゴルフクラブでは、前記インサートの周面に設けた環状凹み部にロッキング部材(ボルト)の先端を径方向から当接させたり、あるいは、前記シャフト角度調整ケースのネジ孔を螺合ししつ貫通する調整ネジの先端をシャフトの周面に径方向から当接することで、シャフトとヘッドを固定している。このため、後端部がヘッドのヒール側に突出する上記ロッキング部材や調整ネジが、例えば不用意な外力などの何らかの原因で緩むと、せっかく調整したライ角などが解消されてしまう、という問題があった。
However, in the golf clubs disclosed in
本発明は、前記背景技術における問題点を解決し、ライ角やフェイス角などを容易に調整でき、ヘッドとシャフトとの固定が強固で安定するゴルフクラブを提供する、ことを課題とする。 It is an object of the present invention to provide a golf club that solves the problems in the background art described above, can easily adjust the lie angle, face angle, etc., and has a strong and stable fixation between the head and the shaft.
本発明は、上記課題を解決するため、シャフトの先端部をヘッドのヒール側でホーゼルに開口する挿入穴内で角度を変更可能としつつ強固且つ安定して固定できるようにする、ことに着想して成されたものである。
即ち、本発明のゴルフクラブ(請求項1)は、ヘッド本体のホーゼルに上端が開口し且つ底面がソールのヒール寄りに位置する挿入穴を有するゴルフクラブヘッドと、上記挿入穴にシャフトと共に挿入され、且つ係るシャフトの先端部に接着される筒形の本体、および係る本体の底面に開口する雌ネジ孔を備える取替可能な角度調整パーツと、上記ヘッドのソール側から上記挿入穴の底面に貫通し且つ上記角度調整パーツの雌ネジ孔にネジ結合する固定ボルトと、を含む、ことを特徴とする。
また、本発明には、前記角度調整パーツは、前記シャフトの先端部を受け入れる凹部を内設すると共に、係る凹部の中心軸が上記シャフトの中心軸と一致するものと、一致しない単数または複数のもの、との複数が用意されている、ゴルフクラブ(請求項2)も含まれる。
In order to solve the above-mentioned problems, the present invention has been conceived to enable the tip of the shaft to be firmly and stably fixed while allowing the angle to be changed within an insertion hole opened in the hosel on the heel side of the head. It was made.
That is, the golf club of the present invention (Claim 1) is inserted together with a golf club head having an insertion hole whose upper end is opened in the hosel of the head body and whose bottom surface is located near the heel of the sole together with the shaft into the insertion hole. And a cylindrical main body bonded to the tip of the shaft, a replaceable angle adjusting part having a female screw hole opening in the bottom surface of the main body, and a bottom side of the insertion hole from the sole side of the head And a fixing bolt that passes through and is screw-coupled to the female screw hole of the angle adjusting part.
Further, in the present invention, the angle adjusting part is provided with a recess for receiving the tip portion of the shaft, and the center axis of the recess corresponds to the center axis of the shaft or a plurality of the axis adjustment parts that do not match with the center axis of the shaft. A golf club (claim 2) is also included in which a plurality of things are prepared.
これらによれば、前記角度調整パーツを取り替えることにより、所望のライ角、フェース角、およびロフト角に素人でも迅速且つ容易に調整できる。また、角度調整パーツおよび固定ボルトは、ヘッド本体の内部に位置するため、何らかの外力よって固定ボルトと角度調整パーツの雌ネジ孔とのネジ結合が緩んで、上記調整したライ角などが解消されず安定して保たれるので、安心してプレイすることができる。しかも、構成部品数が少ないため、容易に角度調整できるゴルフクラブを安価に提供することも可能となる。
尚、前記ゴルフクラブには、ウッド(ドライバー、フェアウェイウッド)などに限らず、前記角度調整パーツが適用可能なアイアンも含まれる。また、前記ヘッドには、例えばチタン合金などを精密鋳造したウッドなどの他、チタン合金板またはステンレス鋼板を溶接などで組み立てたウッドなど、あるいは、パーシモンなどからなるウッドも含まれる。
According to these, by replacing the angle adjusting parts, even an amateur can quickly and easily adjust the desired lie angle, face angle, and loft angle. In addition, since the angle adjustment part and the fixing bolt are located inside the head body, the screw connection between the fixing bolt and the female screw hole of the angle adjustment part is loosened by some external force, and the adjusted lie angle etc. cannot be resolved. Because it is kept stable, you can play with confidence. In addition, since the number of components is small, it is possible to provide a golf club that can easily adjust the angle at low cost.
The golf club is not limited to wood (driver, fairway wood) or the like, but also includes an iron to which the angle adjustment part can be applied. The head includes, for example, wood obtained by precision casting of a titanium alloy, wood obtained by welding a titanium alloy plate or stainless steel plate by welding, or wood made of persimmon.
更に、本発明には、前記角度調整パーツの外側面と前記ヘッドの挿入穴の内壁面とには、互いに面接触可能な非円形断面の接触面がそれぞれ形成されているか、あるいは、凸条とこれを受け入れる凹溝との何れか一方が形成されている、ゴルフクラブ(請求項3)も含まれる。
これによれば、角度調整パーツとヘッドとを相対的に回転不能にできるため、前述の調整したライ角などが解消されず安定して保つことができる。
尚、上記接触面は、角度調整パーツの外側面の一部と前記ヘッドの挿入穴の内壁面の一部とに設けた一対の平坦面のほか、これらを含む四角柱や六角柱を呈する外側面および内壁面が含まれる。
Further, according to the present invention, the outer surface of the angle adjusting part and the inner wall surface of the insertion hole of the head are each formed with a contact surface having a non-circular cross section that can come into surface contact with each other, or A golf club (Claim 3) in which any one of the concave grooves for receiving the groove is formed is also included.
According to this, since the angle adjustment part and the head can be relatively unrotatable, the adjusted lie angle and the like described above can be stably maintained without being eliminated.
The contact surface includes a pair of flat surfaces provided on a part of the outer surface of the angle adjustment part and a part of the inner wall surface of the insertion hole of the head, and an outer surface that exhibits a square column or a hexagonal column including these. Side and inner wall surfaces are included.

The head H is, for example, a hollow body containing a hollow portion n obtained by precision casting of a titanium alloy. As shown in FIG. 1, the face 3, the sole 4, the crown 5, the
角度調整パーツC1は、例えばチタン合金またはアルミニウム合金の鋳造材または鍛造材からなり、図3中の左上の外観および中央上の断面で示すように、円筒形(筒形)の本体12、その内側に軸方向に沿って内設する円柱形の凹部13、および本体12の底面14の中央に開口した雌ネジ孔15を備えている。係る雌ネジ孔15には、前記固定ボルト16がネジ結合する。上記凹部13の中心軸は、本体12の中心軸と一致(同軸心)している。また、上記本体12の外径は、ヘッドHの前記挿入穴10の内径とほぼ同じか、僅かに小径である。
図示のように、本体12の底面14寄りには、断面正六角形(非円形断面)の接触面12aが形成されている。図3の下方に示すように、ヘッドHの挿入穴10の底面寄りには、上記接触面12aと面接触可能な断面正六角形(非円形断面)の接触面11が形成されている。
The angle adjusting part C1 is made of, for example, a cast material or a forged material of titanium alloy or aluminum alloy. As shown in the upper left appearance and the cross section on the center in FIG. 3, the cylindrical (cylindrical)
As shown in the figure, a
ゴルフクラブ1は、以下のようにして組み立てられる。
先ず、図1,3に示すように、角度調整パーツC1を、その凹部13にシャフトSの先端部を熱軟化性接着剤を介して嵌入することで、当該シャフトSの先端部に接着する。尚、係る接着に先立って、シャフトSの中間にキャップ18を挿通しておく。
次いで、図3中の一点鎖線の矢印で示すように、キャップ18を挿通したシャフトSの先端部を、角度調整パーツC1と共に、ヘッドHの挿入穴10にホーセル7側から挿入する。この際、互いに非円形断面である上記パーツC1の接触面12aと、挿入穴10の接触面11とが面接触するように挿入する。この結果、シャフトSおよび角度調整パーツC1とヘッドHとが、相互に回転不能となる。
The
First, as shown in FIGS. 1 and 3, the angle adjusting part C <b> 1 is bonded to the tip end portion of the shaft S by fitting the tip end portion of the shaft S into the
Next, as indicated by the one-dot chain line arrow in FIG. 3, the tip of the shaft S through which the
更に、図3の下方に示すように、固定ボルト16の雄ネジ部を、ヘッドHの通し孔9を貫通させてから、図1に示すように、角度調整パーツC1の雌ネジ孔15にネジ結合する。最後に、キャップ18をヘッドHのホーゼル7上に移動させる。この結果、図1に示すようなゴルフクラブ1が組み立てられる。
このゴルフクラブ1は、角度調整パーツC1の本体12と凹部13とが、互いに同軸心であるので、シャフトSの中心線は、挿入穴10と同軸心となる。このため、図1に示すように、シャフトSは、ソール4との間で、ヘッドHのホーゼル7に付された本来のライ角αを形成する。
Further, as shown in the lower part of FIG. 3, the male screw portion of the
In this
次に、例えばゴルファーの身長を考慮して、図2に示すように、前記ライ角αをやや小さく調整する場合について説明する。
先ず、固定ボルト16を緩めて取り外した後、角度調整パーツC17やキャップ18と共にシャフトSを、ヘッドHの挿入穴10から上方に抜き出す。上記パーツC1を炙って接着剤を軟化させ、シャフトSから取り外す。当該シャフトSの先端部に残った接着剤を削るなどして除去する。
次に、図3中の右上に示すような角度調整パーツC2を用意する。
係るパーツC2は、ほぼ円筒形の本体12と、係る本体12の底面14の中央に開口した雌ネジ孔15と、前記同様の接触面11とを有する。また、本体12の内側には、当該本体12の中心軸に対し、図2,図3において、時計方向に沿って上端の開口部が0.5〜3度傾斜した中心軸の凹部13aが形成してある。
Next, a case where the lie angle α is adjusted slightly smaller as shown in FIG. 2 in consideration of the height of the golfer will be described.
First, after loosening and removing the
Next, an angle adjustment part C2 as shown in the upper right in FIG. 3 is prepared.
The part C <b> 2 includes a substantially cylindrical
図3中の右上に示すように、角度調整パーツC2の凹部13aにシャフトSの先端部を熱軟化性接着剤を介して嵌入し、上記パーツC2を当該シャフトSの先端部に接着する。
次いで、図3中の二点鎖線の矢印で示すように、キャップ18を挿通したシャフトSの先端部を、角度調整パーツC2と共に、ヘッドHの挿入穴10にホーセル7側から挿入する。この際、互いに非円形断面の上記パーツC2の接触面12aと、挿入穴10の接触面11とが面接触するように挿入する。
As shown in the upper right in FIG. 3, the tip of the shaft S is fitted into the
Next, as indicated by a two-dot chain line arrow in FIG. 3, the tip of the shaft S through which the
更に、図3の下方に示すように、固定ボルト16の雄ネジ部を、ヘッドHの通し孔9に貫通させ、図2に示すように、角度調整パーツC2の雌ネジ孔15にネジ結合する。最後に、キャップ18をヘッドHのホーゼル7上方に移動させる。この結果、図2に示すようなゴルフクラブ1が組み立てられる。
このゴルフクラブ1は、角度調整パーツC2の本体12の中心軸に対して凹部13aの中心軸が、図2,図3で時計方向に傾いているため、シャフトSの中心線は、挿入穴10の中心線よりも図2,図3で時計方向に0.5〜3度傾斜する。このため、図2に示すように、シャフトSは、ソール4との間で、ヘッドHのホーゼル7に付された前記ライ角αよりも小さなライ角αを形成することができる。
Further, as shown in the lower part of FIG. 3, the male screw portion of the
In this
図4は、異なる角度調整パーツC1′を用いたヘッドHの部分垂直断面を含む正面図、図5は、図4中のX−X線に沿った矢視における部分断面図である。
図4,図5に示すように、角度調整パーツC1′は、円筒形の本体12と、係る本体12の内側に同軸心に形成された凹部13と、本体12の底面14の中央に開口した雌ネジ孔15と、本体12の外側に軸方向沿って突設した凸条17と、を備えている。但し、前記接触面12aは、形成されていない。
一方、ヘッドHの挿入穴10には、図5に示すように、中空部n寄りに延びた凹溝7aが軸方向に沿って形成されている。
4 is a front view including a partial vertical cross section of the head H using different angle adjustment parts C1 ′, and FIG. 5 is a partial cross sectional view taken along the line XX in FIG.
As shown in FIGS. 4 and 5, the angle adjusting part C <b> 1 ′ is opened at the center of the cylindrical
On the other hand, in the
従って、シャフトSと共に角度調整パーツC1′を、ヘッドHの挿入穴10に挿入する際、図4,図5に示すように、凸条17が凹溝7aに受け入れられるよう嵌合することで、シャフトSおよび上記パーツC1′とヘッドHとを回転不能にできる。係る状態で、前記固定ボルト16を上記パーツC1′の雌ネジ孔15によって、図4に示すゴルフクラブ1が組み立てられる。
尚、前記接触面11を省略した前記角度調整パーツC2の本体12に凸条17を突設しても良く、挿入穴10に凹溝7aを有するヘッドHに回転不能に挿入して固定することができる。また、凹溝7aは、ヘッドHの挿入穴10内にて、バックフェース3′側で且つフェース面3とほぼ直交する向きで形成しても良い。
Therefore, when inserting the angle adjusting part C1 ′ together with the shaft S into the

また、前記角度調整パーツC2における凹部13aの中心軸の傾斜方向を、図7に示すように、ヘッドHにおけるフェース3の斜め上方向またはバックフェイス3′の斜め下方向に沿うように、シャフトSと共に前記挿入穴10内に挿入し且つ固定ナット16をネジ結合させることもできる。
この結果、図7に示すように、ロフト角γを当初の状態よりも、上下方向に約0.5度〜3度調整することが容易に行える。尚、この場合、ロフト角γの調整と同時に、ライ角αも変化し得ることに、留意する必要がある。
Further, as shown in FIG. 7, the shaft S is arranged so that the inclination direction of the central axis of the
As a result, as shown in FIG. 7, the loft angle γ can be easily adjusted by about 0.5 to 3 degrees in the vertical direction from the initial state. In this case, it should be noted that the lie angle α can be changed simultaneously with the adjustment of the loft angle γ.
