Description

本発明は、ロフト角度が13度以上のウッドクラブヘッド、いわゆるフェアウェイウッドと呼ばれるヘッドに関する。   The present invention relates to a wood club head having a loft angle of 13 degrees or more, a head called a so-called fairway wood.

従来のフェアウェイウッドは、フェース面から重心までの距離を重心深さ(ZG)とし、シャフト軸線からフェース先端(リーディングエッジ)までの距離をフェースプログレッション(FP)とし、ホゼルの円筒部分の長さをホゼル長さとしたとき、これらの値を種々変えたりして、スピン量やボールのつかまり易さなどを設計していた。ZGの値が大きなものは、インパクトでフェースが上向きになり易く、スピンもかかり易く、ボールが上がり易くなる。FPの値が大きいほどボールの上がり易さが増すが、ボールのつかまりは悪くなる。ロフト角度は、フェース面をスクエアな状態にしたときのシャフトとフェース面の角度の測定値であり、フェース面の上向き角度である。ヘッドスピードが速くない一般ゴルファーにとっては、ボールのつかまりをよくしてボールにスピンをかけて上がり易く設計されるのが一般的であった。   In the conventional fairway wood, the distance from the face surface to the center of gravity is the center of gravity depth (ZG), the distance from the shaft axis to the tip of the face (leading edge) is the face progression (FP), and the length of the cylindrical part of the hosel is When the hosel length was used, these values were changed in various ways to design the amount of spin and the ease of holding the ball. When the value of ZG is large, the face is likely to face upward due to impact, the spin is likely to be applied, and the ball is likely to rise. The greater the FP value, the easier the ball will rise, but the ball will become more difficult to catch. The loft angle is a measured value of the angle between the shaft and the face surface when the face surface is in a square state, and is an upward angle of the face surface. For general golfers who do not have a fast head speed, it is common to design the ball so that it can be easily lifted by spinning the ball.

FP値に注目したゴルフクラブヘッドとしては、FP値を7mm以上20mm以下の範囲としたものが知られている(特許文献1参照)。また、重心深さ(ZG)に注目したものも知られている(特許文献2参照)。
特開平11−178958号公報(第3頁、図1) 特開2002−210045号公報(第4頁、図2)
As a golf club head paying attention to the FP value, one having an FP value in the range of 7 mm or more and 20 mm or less is known (see Patent Document 1). Moreover, what paid attention to the gravity center depth (ZG) is also known (refer patent document 2).
Japanese Patent Laid-Open No. 11-178958 (page 3, FIG. 1) Japanese Patent Laid-Open No. 2002-210045 (page 4, FIG. 2)

特許文献1,2に記載のいずれのゴルフクラブヘッドも、フェアウェイウッドのZG、FP値、ホゼルの長さを組み合わせた設計を行ってヘッドスピードの速いゴルファーに打ち易いゴルフクラブを提供するというものではなかった。ZG及びFP値の設計によりボールを上がり易くしただけのものでは、ヘッドスピードの速いゴルファーがボールをヒットすると、ボールが吹け上がってしまい、風に弱く、飛距離をロスする傾向にあった。   Any of the golf club heads described in Patent Documents 1 and 2 is designed to provide a golf club that is easy to hit a golfer with a fast head speed by designing a combination of fairway wood ZG, FP value, and hosel length. There wasn't. In the case where the ball is easily raised by the design of the ZG and FP values, when a golfer with a high head speed hits the ball, the ball is blown up, weak against the wind, and tends to lose the flight distance.

そこで、本発明は、ホゼルの長さにも着目し、ホゼルの長短に応じてヘッドスピードの速いゴルファーがボールをヒットした際にボールは上がり易いが吹け上がらずに、弾道が強く飛距離も出るウッドクラブヘッドを提供することを目的とする。   Therefore, the present invention also pays attention to the length of the hosel, and when a golfer with a fast head speed hits the ball according to the length of the hosel, the ball is easy to rise but does not blow up, the trajectory is strong and the flight distance also appears An object is to provide a wood club head.

上述の目的を達成するため、本発明は、ロフト角度が13度以上のいわゆるフェアウェイウッドのウッドクラブヘッドであって、ホゼル長さを20mm〜40mmの範囲内に形成し、フェースプログレッションを12mm超16mm未満に設定し、重心深さを20mm超25mm未満に設定した。また、ロフト角度が13度以上のいわゆるフェアウェイウッドのウッドクラブヘッドであって、ホゼル長さを20mm未満に設定し、フェースプログレッションを16mm超20mm未満に設定し、重心深さを25mm超30mm未満に設定し、重心高さを18mm以下とした。 In order to achieve the above-mentioned object, the present invention is a so-called fairway wood club head having a loft angle of 13 degrees or more, having a hosel length in the range of 20 mm to 40 mm, and a face progression of more than 12 mm to 16 mm. The center of gravity depth was set to more than 20 mm and less than 25 mm. Also, a so-called fairway wood club head with a loft angle of 13 degrees or more, the hosel length is set to less than 20 mm, the face progression is set to more than 16 mm and less than 20 mm, and the center of gravity depth is set to more than 25 mm and less than 30 mm. The center of gravity was set to 18 mm or less.

本発明によれば、ロフト角度が13度以上のいわゆるフェアウェイウッドのウッドクラブヘッドであって、ホゼル長さを20mm〜40mmの範囲内に形成し、フェースプログレッションを12mm超16mm未満に設定し、重心深さを20mm超25mm未満に設定したので、ホゼルが長いことにより、インパクトがスイープ(鈍角)な軌道となり、ロフト角度が寝気味でボールをヒットし、ボールが上がり易くなるが、ZG及びFP値を小さくすることで吹け上がらず、強い弾道を得ることができる。また、飛距離も出る。 According to the present invention, a so-called fairway wood club head having a loft angle of 13 degrees or more, the hosel length is formed within a range of 20 mm to 40 mm, the face progression is set to more than 12 mm and less than 16 mm, Since the depth is set to more than 20 mm and less than 25 mm, the long hosel makes the impact a sweep (obtuse angle) trajectory, hitting the ball with a loft angle, and making it easier to raise the ball, but the ZG and FP values By reducing, you can get a strong trajectory without blowing up. In addition, the flight distance also appears.

また、ロフト角度が13度以上のいわゆるフェアウェイウッドのウッドクラブヘッドであって、ホゼル長さを20mm未満に設定し、フェースプログレッションを16mm超20mm未満に設定し、重心深さを25mm超30mm未満に設定し、重心高さを18mm以下としたものにあっては、ホゼルが短いことにより、その分スイングの中でインパクトがダウンブロウ(鋭角)な軌道となりロフトが立ち気味でボールが上がりづらくなるが、FP値を大きくし開き気味にアタックし、ZGを大きくしてスピンがかかり易くして、ボールの吹け上がりを防ぎ、強い弾道を得、飛距離も出る。 Also, a so-called fairway wood club head with a loft angle of 13 degrees or more, the hosel length is set to less than 20 mm, the face progression is set to more than 16 mm and less than 20 mm, and the center of gravity depth is set to more than 25 mm and less than 30 mm. If the center of gravity is set to 18mm or less , the hosel is short, so the impact will be down-blow (acute angle) in the swing and the loft will stand up and the ball will not rise easily. , Increase the FP value and attack openly, increase ZG to make it easier to spin, prevent the ball from blowing up, obtain a strong trajectory, and increase the flight distance.

以下に、本発明の好適な実施形態について、図面を参照にして説明する。   Preferred embodiments of the present invention will be described below with reference to the drawings.

図1及び図2は、ロフト角度が13度以のウッドクラブヘッドの側面図と正面図を示し、ヘッド本体1にホゼル2が設けられ、このホゼル2に図示しないシャフトが装着される。ヘッド本体1のフェース面3から重心までの距離を重心深さZGという。また、ホゼル2の長さHLは、円筒部分の長さをいい、シャフト軸線Sからリーディングエッジ4までの距離をフェースプログレッション(FP)という。 1 and 2, a loft angle in a side view and a front view of a wood club head on 13 degrees or, hosel 2 is provided in the head body 1, a shaft (not shown) to the hosel 2 is mounted. The distance from the face surface 3 of the head body 1 to the center of gravity is referred to as the center of gravity depth ZG. The length HL of the hosel 2 refers to the length of the cylindrical portion, and the distance from the shaft axis S to the leading edge 4 is referred to as face progression (FP).

前記ヘッド本体1は、ステンレス鋳造のものを用い、体積を150〜250cmの範囲内とし、ヘッド重量を200g〜250gの範囲内とし、ヘッド本体1のソール5から重心位置CGまでの垂直距離を重心高さとしたとき、重心高さを18mm以下に設計し、クラブ長を43インチ以下、総重量300g以上のフェアウェイウッドにおいて、FP値(mm)、ZG値(mm)、ホゼル長(mm)を変えたものを実施例1,2及び比較例1〜6として製造し、ヘッドスピード45mm/sec〜50mm/secのゴルファーが実打し、各々の打出し角とスピン量を計測した。 The head body 1 is made of stainless steel, has a volume in the range of 150 to 250 cm 3 , has a head weight in the range of 200 to 250 g, and has a vertical distance from the sole 5 of the head body 1 to the center of gravity position CG. The center of gravity height is designed to be 18 mm or less, and the FP value (mm), ZG value (mm), and hosel length (mm) are set for a fairway wood with a club length of 43 inches or less and a total weight of 300 g or more.

本発明では、ホゼル長HLが20mmを超える場合のFP値(mm)は、12<FP<16、とし、ZG値(mm)は、20<ZG<25、とすることが、ヘッドスピードの速い(45m/sec)ゴルファーには向いていることを究明したものである。なお、重心高さを18mm以下にするには、ホゼル長HLを最大35〜40mm以下にすることが望ましい。この場合、ホゼル2は比重の軽いチタンやその合金などで形成することで、ホゼル長HLを長くしても重心高さを低くすることができる。   In the present invention, when the hosel length HL exceeds 20 mm, the FP value (mm) is 12 <FP <16, and the ZG value (mm) is 20 <ZG <25. (45m / sec) It has been found that it is suitable for golfers. In order to reduce the height of the center of gravity to 18 mm or less, the hosel length HL is desirably 35 mm to 40 mm at the maximum. In this case, the hosel 2 is formed of titanium having a low specific gravity or an alloy thereof, so that the height of the center of gravity can be lowered even if the hosel length HL is increased.

ホゼル長HLが20mm未満のショートホゼルに設計した場合(0<H<20)、16<FP<20、25<ZG<30とする。0<HL<20のショートホゼルの場合、インパクトがダウンブロウな軌道となり、ロフトが立ってインパクトするのでボールが上がりにくくなるが、FP及びZGを大きくすることで、ボールが上がり、吹け上がらず、強い弾道となる。その結果、飛距離も出る。   When a short hosel with a hosel length HL of less than 20 mm is designed (0 <H <20), 16 <FP <20 and 25 <ZG <30. In the case of a short hosel with 0 <HL <20, the impact becomes a down-blow trajectory, and the loft stands and impacts, making it difficult for the ball to rise. It becomes a trajectory. As a result, the flight distance also appears.

ヘッド重量は、本体が190g以上、余重量(タングステンウェート等を適宜個所に付加)が30g以上とすることが望ましく、体積は150〜250cm、重心高さが18mm以下が望ましく、ヘッド本体1がステンレス鋳造であることが望ましい。また、#3〜#5フェアウェイウッドのヘッド体積、クラブ長、総重量を例えば次のように設定し、ショートホゼルの場合とロングホゼルの場合のFPとZGの各値を上述の範囲内とした。
#3…168cm…42.5インチ …329g
#4…160cm…42.25インチ…331g
#5…155cm…42インチ …333g
The head weight is preferably 190 g or more for the main body, and the surplus weight (tungsten weight or the like is appropriately added) is 30 g or more, the volume is preferably 150 to 250 cm 3 , and the center of gravity height is 18 mm or less. Stainless steel casting is desirable. Further, the head volume, club length, and total weight of # 3 to # 5 fairway wood were set as follows, for example, and the values of FP and ZG in the case of the short hosel and the long hosel were set in the above-mentioned ranges.
# 3… 168cm 3 … 42.5 inches… 329g
# 4 ... 160cm 3 ... 42.25 inch ... 331g
# 5… 155cm 3 … 42 inches… 333g
