Description

本発明はゴルフクラブヘッド、殊にドライバーやスプーンやバフィー等のヘッドのフェースプレートに高反発性を付与したゴルフクラブヘッドに関する。   The present invention relates to a golf club head, and more particularly to a golf club head in which high resilience is imparted to a face plate of a head such as a driver, spoon or buffy.

特許文献１においては、ヘッドのフェースプレートの裏側（内表面）に、半円形の補強線材を打撃スポットを中心にして放射状に配し、該補強線材をフェースプレートの内表面に一体的に設けたゴルフクラブヘッドを開示している。
特開２００２−３２０６９２号公報 In Patent Document 1, a semicircular reinforcing wire is arranged radially around the hitting spot on the back side (inner surface) of the face plate of the head, and the reinforcing wire is integrally provided on the inner surface of the face plate. A golf club head is disclosed.
JP 2002-320692 A

而して上記先行例は補強線材を打撃スポットを中心に放射状に配して、打撃スポットでゴルフボールを捉えた時のフェースプレートの反発力を増加し飛距離アップに寄与せんとするものであり、打撃スポットから外れたフェース面においてゴルフボールを捉えた時には、その効果が適切に得られるとは言い難い。   Thus, in the preceding example, reinforcing wire rods are arranged radially around the hitting spot to increase the repulsive force of the face plate when the golf ball is captured at the hitting spot, thereby contributing to an increase in flight distance. When a golf ball is captured on a face surface that is out of the hitting spot, it is difficult to say that the effect is properly obtained.

又補強線材をフェースプレートの内表面に一体的に延設して補強を図る構造であるため、補強線材が常に同プレートによって拘束され、補強線材が単独で自由に撓み、高反発性を生起せしめることができない。   In addition, since the reinforcing wire is integrally extended to the inner surface of the face plate for reinforcement, the reinforcing wire is always constrained by the same plate, and the reinforcing wire is flexed independently and causes high resilience. I can't.

又上記先行例においては、補強線材を接着材等によりフェースプレートの内表面に貼り付けるものと推察されるが、線材の剥離、落下を生ずる恐れを有している。殊にフェースプレートはゴルフボールを打撃する都度、内方へ撓むのでこの剥離落下の問題を助長する。   In the preceding example, it is presumed that the reinforcing wire is attached to the inner surface of the face plate with an adhesive or the like, but there is a risk that the wire will be peeled off or dropped. In particular, the face plate bends inward every time it hits a golf ball, thus aggravating the problem of peeling and dropping.

本発明に係るゴルフクラブヘッドにおいては、フェースプレートの内表面に沿って複数本の弾性線材を並行して配し、該弾性線材をフェースプレートの内表面に接触又は僅かな間隙を存して延在せしめると共に、該弾性線材の両端を上記フェースプレートの周域部において固定し、両端固定部間における自由な弾性変位を許容する構成とした。   In the golf club head according to the present invention, a plurality of elastic wires are arranged in parallel along the inner surface of the face plate, and the elastic wires are extended in contact with the inner surface of the face plate or with a slight gap. At the same time, both ends of the elastic wire are fixed at the peripheral area of the face plate to allow free elastic displacement between the both ends fixed.

上記フェースプレートの内表面に沿って並行に配された弾性線材は、フェースプレートの打撃スポットを含む広領域において高反発性を生起し飛距離アップを図ることができ、フェースプレートを薄くして反発性を高める、所謂トランポリン効果を有効に惹起せしめる。   The elastic wire arranged in parallel along the inner surface of the face plate generates high resilience in a wide area including the hit spot of the face plate and can increase the flight distance. The so-called trampoline effect that enhances the properties is effectively induced.

又上記弾性線材はフェースプレートの内表面に接触又は僅かな間隙を存して延在するので、フェースプレートに対し自由に撓みを生じてフェースプレートに高反発力を与え、弾性線材の弾性を飛距離アップに有効に寄与せしめることができる。   Further, since the elastic wire extends in contact with the inner surface of the face plate or with a slight gap, it flexes freely with respect to the face plate to give a high repulsive force to the face plate, and the elasticity of the elastic wire is radiated. It is possible to make an effective contribution to increasing the distance.

又弾性線材は上記撓みを生じた時の負荷が両端固定部に加わり、前記弾性線材の剥落等の問題を解消できる。   In addition, the load when the elastic wire is bent is applied to both end fixing portions, and problems such as peeling of the elastic wire can be solved.

適例として、上記弾性線材はその両端をヘッド本体の前縁部に接着材又は溶接にて固定し、両固定部間における自由な弾性変位を許容する。   As an appropriate example, both ends of the elastic wire are fixed to the front edge of the head main body by an adhesive or welding, and free elastic displacement is allowed between the two fixed portions.

上記弾性線材としては、ピアノ線に代表される鋼線材等の金属線材を用いる。又は弾性線材としてカーボン線材又はボロン線材を用いる。   As the elastic wire, a metal wire such as a steel wire represented by a piano wire is used. Alternatively, a carbon wire or a boron wire is used as the elastic wire.

以下本発明を実施するための最良の形態を図１乃至図１８に基づき説明する。   The best mode for carrying out the present invention will be described below with reference to FIGS.

図２，図５，図８等に示すように、ゴルフクラブの金属製のヘッド本体１は中空構造であり、前面の開口はチタン等の金属製のフェースプレート２で閉鎖されている。即ちヘッド本体１とフェースプレート２とを別部品にて形成し、ヘッド本体１の前縁部にフェースプレート２を溶接等にて取り付け中空構造にする。   As shown in FIGS. 2, 5, 8, etc., the metal head body 1 of the golf club has a hollow structure, and the opening on the front surface is closed with a metal face plate 2 such as titanium. That is, the head body 1 and the face plate 2 are formed as separate parts, and the face plate 2 is attached to the front edge of the head body 1 by welding or the like to form a hollow structure.

図１，図４，図７等に示すように、上記フェースプレート２の内表面に沿って複数本の弾性線材３を並行して配し、図１７に示すように、該弾性線材３をフェースプレート２の内表面に接触して延在せしめる。即ち弾性線材３とフェースプレート２の内表面とは自由接触面を形成している。   As shown in FIG. 1, FIG. 4, FIG. 7, etc., a plurality of elastic wires 3 are arranged in parallel along the inner surface of the face plate 2, and as shown in FIG. It extends in contact with the inner surface of the plate 2. That is, the elastic wire 3 and the inner surface of the face plate 2 form a free contact surface.

上記弾性線材３はフェースプレート２の略全幅に接触させる他、図１４に示すように、フェースプレート２の内表面中央部に膨出部１１を一体に形成し、該膨出部１１に接触して延在せしめ、弾性線材３の両端延在部はフェースプレート２の内表面から離間する。   The elastic wire 3 is brought into contact with substantially the entire width of the face plate 2, and as shown in FIG. 14, a bulging portion 11 is integrally formed at the central portion of the inner surface of the face plate 2, and comes into contact with the bulging portion 11. The both ends of the elastic wire 3 are separated from the inner surface of the face plate 2.

上記膨出部１１は打撃スポットを形成し、この膨出部１１が内方へ撓むことによって、弾性線材３の中央部を集中的に加圧し、これを一緒に内方へ撓ませる。   The bulging portion 11 forms a hitting spot, and when the bulging portion 11 is bent inward, the central portion of the elastic wire 3 is intensively pressed and bent together inward.

又は図１８に示すように、上記弾性線材３をフェースプレート２の内表面に対し、僅かな間隙４を存し延在せしめる。即ち弾性線材３をフェースプレート２の内表面に対し非接触状態で延在せしめ、フェースプレート２が内方へ撓む過程で弾性線材３に接触し一緒に撓むようにする。   Alternatively, as shown in FIG. 18, the elastic wire 3 is extended with respect to the inner surface of the face plate 2 with a slight gap 4. That is, the elastic wire 3 is extended in a non-contact state with respect to the inner surface of the face plate 2, and in contact with the elastic wire 3 in the process of bending the face plate 2 inward, it is bent together.

図１４に示すように、フェースプレート２の内表面に膨出部１１を設ける場合には、図１８に示すように、上記弾性線材３の中央部をこの膨出部１１から僅かに間隙４を存して延在し、常態においては非接触状態とし、フェースプレート２が内方へ撓む過程で膨出部１１が弾性線材３に接触し一緒に撓むようにする。   As shown in FIG. 14, when the bulging portion 11 is provided on the inner surface of the face plate 2, the central portion of the elastic wire 3 is slightly spaced from the bulging portion 11 as shown in FIG. The bulging portion 11 is in contact with the elastic wire 3 and bends together in the process in which the face plate 2 is bent inward.

上記弾性線材３をフェースプレート２の内表面に対し接触又は間隙４を存して延在せしめる何れの場合においても、同線材３の両端を上記フェースプレート２の周域部において固定する。   In any case in which the elastic wire 3 extends in contact with the inner surface of the face plate 2 or with a gap 4, both ends of the wire 3 are fixed at the peripheral area of the face plate 2.

換言すると、弾性線材３は両端をフェースプレート２の周域部において固定し、該固定部間においてフェースプレート２の内表面に対しフリーに延在せしめる。即ち弾性線材３は両端固定部間においてフェースプレート２の内表面に対し接触又は僅かな間隙４を存して延在せしめる。   In other words, both ends of the elastic wire 3 are fixed at the peripheral region of the face plate 2 and freely extend between the fixed portions with respect to the inner surface of the face plate 2. That is, the elastic wire 3 extends between the fixed portions at both ends with contact with the inner surface of the face plate 2 or with a slight gap 4.

フェースプレート２はその外表面でゴルフボールを打撃した場合に、内方へ撓むが、上記弾性線材３はこのフェースプレート２の撓み過程で一緒に内方へ撓み、相乗して反発力を生ずる。   When the golf ball is hit on the outer surface of the face plate 2, the face plate 2 is bent inward, but the elastic wire 3 is bent inward together in the bending process of the face plate 2 to generate a repulsive force. .

弾性線材３の並設態様として図１乃至図３に示すように、同線材３を横方向（略水平方向）に並設する。又は図４乃至図６に示すように、弾性線材３を縦方向（上下方向）に並設する。又は図７乃至図９に示すように、横方向と縦方向に並設する。横方向と縦方向の弾性線材３は互いに交差し接触する。   As shown in FIG. 1 to FIG. 3, the elastic wires 3 are arranged side by side in the horizontal direction (substantially horizontal direction). Alternatively, as shown in FIGS. 4 to 6, the elastic wire 3 is juxtaposed in the vertical direction (vertical direction). Alternatively, as shown in FIGS. 7 to 9, they are arranged side by side in the horizontal direction and the vertical direction.
