Abstract

<P>PROBLEM TO BE SOLVED: To improve durability and repulsion performance and to make a head light in weight. <P>SOLUTION: In a golf club head whose inside is turned to a hollow shape, fine corrugated recesses and projections are formed on the back surface of a face part. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は耐久性と反発性能を向上するとともに、軽量化を図ることができるゴルフクラブヘッドに関する。   The present invention relates to a golf club head capable of improving the durability and resilience performance and reducing the weight.

図３に示すような内部を中空形状としたウッド型ゴルフクラブ１において、ボールが頻繁に衝突するフェース部の中央領域１ａを厚くし、ボールとの衝突の機会が少ない周辺領域１ｂを薄くすることよって、強度の低下を招くことなく高い反発性能を発揮させるものが提案されている（特許文献１）。
また、フェース打撃面の厚みに比して、フェース部からヘッド本体に延びる延長部の厚みを薄くしてその部分の剛性を抑えて反発性能を高めるようにしたものも提案されている（特許文献２）。
特許３０６４９０５号 特開２００３−７７４号 In the wood-type golf club 1 having a hollow shape as shown in FIG. 3, the central region 1a of the face part where the ball frequently collides is thickened, and the peripheral region 1b where the chance of collision with the ball is small is thinned. Therefore, what has demonstrated high resilience performance, without causing the fall of intensity | strength is proposed (patent document 1).
In addition, there has also been proposed a device in which the thickness of the extension extending from the face portion to the head body is reduced compared with the thickness of the face striking surface, thereby suppressing the rigidity of the portion and improving the resilience performance (Patent Literature). 2).
Patent 3064905 JP2003-774

フェース部の厚さを薄くすることにより反発性能を向上できるが、あまり薄くすると耐久性能に問題が生ずる。そのため、特許文献１ではボールが頻繁に衝突するフェース部の中央領域を厚くし、周辺領域を薄くすることよって、強度の低下を招くことなく反発性能を向上させるようにしているが、中央部は厚く、周辺部のみ薄くしているために全体としての軽量化を図ることができない。また、特許文献２においてはフェース面を厚くし、延長部を薄くしているが、同様に全体としての軽量化を図ることができない。   The rebound performance can be improved by reducing the thickness of the face portion, but if it is too thin, there will be a problem in durability. Therefore, in Patent Document 1, the center region of the face portion where the ball frequently collides is thickened and the peripheral region is thinned to improve the resilience performance without causing a decrease in strength. Since it is thick and only the periphery is thin, it is not possible to reduce the overall weight. In Patent Document 2, the face surface is thickened and the extension is thinned. However, the overall weight cannot be reduced.

本発明は上記課題を解決しようとするものであり、耐久性と反発性能を向上するとともに、軽量化を図ることを目的とする。
そのために本発明は、内部を中空形状としたゴルフクラブヘッドにおいて、フェース部背面に細かい凹凸を形成したことを特徴とする。 The present invention is intended to solve the above-described problems, and aims to improve durability and resilience performance and to reduce weight.
Therefore, the present invention is characterized in that in a golf club head having a hollow inside, fine irregularities are formed on the back surface of the face portion.

以上のように本発明によれば以下のような効果が得られる。
1)厚みの薄い凹部の振動により反発性能が向上する。
2)凹部の振動は隣接する凸部で分散して速く減衰する。
3)薄い凹部は隣接する凸部で支持されて支持力が増大しフェース強度と耐久性が向上する。
4)薄い凹部が分布するため全体として薄くでき、ヘッドの軽量化を図ることができる。 As described above, according to the present invention, the following effects can be obtained.
1) The resilience performance is improved by the vibration of the thin concave portion.
2) The vibration of the concave part is dispersed at the adjacent convex part and attenuated quickly.
3) The thin concave portion is supported by the adjacent convex portion, so that the supporting force is increased and the face strength and durability are improved.
4) Since thin concave portions are distributed, the thickness can be reduced as a whole, and the weight of the head can be reduced.

以下、本発明の実施の形態について説明する。
図１は本実施形態のゴルフクラブヘッドを説明する図で、図１（ａ）は側断面図、図１（ｂ）はフェース部平面図、図２はフェース部の振動吸収を説明する図である。
ゴルフクラブヘッド１０のフェース部１１の背面には、例えば、波形形状の小さな凹凸１２が２次元的に分布するように形成されている。もちろん、波形形状に限らず断面矩形の凹凸であってもよい。この凹凸は、例えば凹部におけるフェースの厚みは０．５ｍｍ以下、凸部におけるフェースの厚みは２ｍｍ以上で、平均の厚みは１．５ｍｍ以上とする。 Embodiments of the present invention will be described below.
FIG. 1 is a view for explaining a golf club head of this embodiment, FIG. 1 (a) is a side sectional view, FIG. 1 (b) is a face portion plan view, and FIG. 2 is a view for explaining vibration absorption of the face portion. is there.
On the back surface of the face portion 11 of the golf club head 10, for example, irregularities 12 having a small waveform shape are formed so as to be distributed two-dimensionally. Of course, not only the corrugated shape but also a concave-convex shape with a rectangular cross section may be used. For example, the unevenness has a face thickness of 0.5 mm or less in the recesses, a face thickness of 2 mm or more in the protrusions, and an average thickness of 1.5 mm or more.

図２に示すように、ボールがフェース面へ衝突して力Ｆを受けると、分布して形成された凹凸の薄い凹部が振動して反発性が向上する。一方、凹部で発生した振動はその周囲の厚い凸部に分散して吸収されるため減衰が速い。また、薄い凹部は隣接の厚い凸部で支持されるため、支持力が増大し、全体としてのフェース強度が強く、耐久性能も向上する。さらに、薄い凹部が全体に分布するため、全体としてフェース部を薄くでき、軽量化を図ることが可能である。   As shown in FIG. 2, when the ball collides with the face surface and receives the force F, the thin concave and convex portions formed in a distributed manner vibrate to improve resilience. On the other hand, the vibration generated in the concave portion is dispersed and absorbed by the thick convex portions around it, so that the damping is fast. Further, since the thin concave portion is supported by the adjacent thick convex portion, the supporting force is increased, the face strength as a whole is strong, and the durability performance is also improved. Further, since the thin concave portions are distributed throughout, the face portion can be thinned as a whole, and the weight can be reduced.
