Description

本発明は、ゴルフクラブヘッドの構造に関するもので、特にフェース板の背面に強化板が設けられることにより、構造の強度を増やすことができるゴルフクラブヘッドの構造に係るものである。   The present invention relates to a structure of a golf club head, and more particularly, to a structure of a golf club head that can increase the strength of the structure by providing a reinforcing plate on the back surface of the face plate.

従来のゴルフクラブヘッドの構造としては、図１５、１６に示すように、金属材質によりヘッド１が製成され、ヘッド１にはヘッド本体１０、フェース板１１、環状壁１２、ネック１３および振動吸収片１４が含まれる。フェース板１１はヘッド本体１０の正面に設けられ、フェース板１１は打球するのにもちいられる。環状壁１２はヘッド本体１０の周縁から後方へ延伸するように形成され、環状壁１２はヘッド本体１０の背面において囲むように開口部１２１が形成される。ネック１３はシャフト（図示せず）と結合するのに用いられる。振動吸収片１４はゴムまたはカーボンの材質により製成され、そして粘着層１４１を利用してフェース板１１の背面に粘着して結合することにより、打球時に生じた振動を吸収するようにとしたものがある。   As shown in FIGS. 15 and 16, the conventional golf club head has a head 1 made of a metal material. The head 1 has a head body 10, a face plate 11, an annular wall 12, a neck 13 and vibration absorption. A piece 14 is included. The face plate 11 is provided in front of the head main body 10, and the face plate 11 is used for hitting a ball. The annular wall 12 is formed so as to extend rearward from the periphery of the head body 10, and the opening 121 is formed so as to surround the annular wall 12 on the back surface of the head body 10. The neck 13 is used to couple with a shaft (not shown). The vibration absorbing piece 14 is made of a rubber or carbon material, and uses the adhesive layer 141 to adhere and bond to the back surface of the face plate 11 so as to absorb vibration generated at the time of hitting the ball. There is.

また、従来のゴルフクラブヘッドの構造としては、金属製ヘッド本体のフェース部にその周縁部を残して貫通孔を形成し、ヘッド本体より比重の小さな高弾性材料からなるフェースプレートを、該当貫通孔の周縁に設けた嵌着凹部で支持してフェース部に取り付けると共に、フェースプレートの裏面側に、フェースプレートより弾性の小さい材料からなる振動吸収材料をヘッド本体と離間させて取り付けたようにとしたものがある（例えば、特許文献１を参照）。
日本国特開平８−１６４２２９号 In addition, as a conventional golf club head structure, a face plate made of a highly elastic material having a specific gravity smaller than that of the head main body is formed by leaving a peripheral edge of the face portion of the metal head main body and leaving a peripheral portion thereof. It was attached to the face part by being supported by a fitting recess provided on the periphery of the face plate, and a vibration absorbing material made of a material having a smaller elasticity than the face plate was attached to the back surface side of the face plate separately from the head body. There are some (see, for example, Patent Document 1).
Japanese Unexamined Patent Publication No. 8-164229

上記のような従来のゴルフクラブヘッドの構造においては、図１６に示すように、フェース板１１は溶接、ろう付け、嵌設または圧着などの方式によりヘッド本体１０のフェース板結合部１０１に結合された時、フェース板１１とヘッド本体１０との境界には結合端縁１１１が形成され、例えば溶接路、ろう付けの溢材、嵌合位置または圧着位置である。打球時において、打球時に生じた振動により結合端縁１１１の付近では応力集中の現象が生じる。もし結合端縁１１１において上記応力集中を長期的に受けると、結合端縁において亀裂が生じるかもしれず、そしてヘッド１の構造の強度に影響を及ぼしてしまう。上記従来のヘッド１には振動吸収片１４が設けられているが、振動吸収片１４の粘着による結合の方式では振動吸収片１４とヘッド本体１０の間に隙間１４２が生じ易いという問題点は避けられない。その結果、実際に使用すると、振動吸収片１４は隙間１４２の阻隔により結合端縁１１１の集中応力を吸収することができず、さらに振動吸収片１４も粘着層１４１の阻隔によりフェース板１１の振動を吸収する効率は大幅に低減されるという問題点があった。さらに、フェース板１１の背面において支持の構造が欠けているため、フェース板１１は比較的大きい厚さを有するように形成しなければならず、それによりフェース板１１が長期的な打球による永久変形が生じるのを避けることができ、しかし、もしフェース板１１に過大な厚さを有するように形成されると、弾性による変形能力も必然的に低くなるため、打球の応力が球体への転移の効率に影響を及ぼしてしまい、さらにヘッド１に振動を与えてしまうかもしれないため、ヘッド１の打球の性能と打球の安定性に大幅に影響を及ぼしてしまうという問題点があった。   In the conventional golf club head structure as described above, as shown in FIG. 16, the face plate 11 is coupled to the face plate coupling portion 101 of the head body 10 by a method such as welding, brazing, fitting or crimping. In this case, a coupling edge 111 is formed at the boundary between the face plate 11 and the head body 10, for example, a welding path, brazing overflow material, a fitting position, or a crimping position. At the time of hitting, a stress concentration phenomenon occurs in the vicinity of the coupling edge 111 due to vibration generated at the time of hitting. If the stress concentration at the joint edge 111 is received for a long time, cracks may occur at the joint edge, which affects the strength of the structure of the head 1. The conventional head 1 is provided with the vibration absorbing piece 14, but the problem of the gap 142 easily occurring between the vibration absorbing piece 14 and the head main body 10 is avoided in the bonding method of the vibration absorbing piece 14 by adhesion. I can't. As a result, when actually used, the vibration absorbing piece 14 cannot absorb the concentrated stress of the coupling end 111 due to the gap 142 and the vibration absorbing piece 14 also vibrates the face plate 11 due to the blocking of the adhesive layer 141. There is a problem in that the efficiency of absorbing water is greatly reduced. Further, since the supporting structure is lacking on the back surface of the face plate 11, the face plate 11 must be formed to have a relatively large thickness, whereby the face plate 11 is permanently deformed by long-term hitting. However, if the face plate 11 is formed so as to have an excessive thickness, the deformability due to elasticity is inevitably low, so that the stress of the hitting ball causes the transition to the sphere. There is a problem in that the efficiency of the hit ball of the head 1 and the stability of the hit ball are greatly affected because the efficiency may be affected and the head 1 may be vibrated.

さらに、上記のような従来のゴルフクラブヘッドの構造においては、フェースプレートより弾性の小さい材料からなる振動吸収材料を接着剤又は溶着や圧着によってヘッド本体と離間させて取り付けることにより、打球時に生じた振動を吸収することができるが、振動吸収材料の粘着による結合の方式では振動吸収材料とヘッド本体の間に隙間が生じ易いという問題点は避けられないため、振動吸収材料は隙間の阻隔により結合端縁の集中応力を吸収することができず、さらに振動吸収材料は粘着層の阻隔によりフェース板の振動を吸収する効率は大幅に低減されるという問題点があった。このように、上記のような従来のゴルフクラブヘッドの構造をさらに改良しなければならない。   Further, in the structure of the conventional golf club head as described above, it is generated at the time of hitting a ball by attaching a vibration absorbing material made of a material having a smaller elasticity than that of the face plate to be separated from the head body by an adhesive, welding, or pressure bonding. Although vibration can be absorbed, the problem that a gap is likely to occur between the vibration absorbing material and the head body is unavoidable in the bonding method of vibration absorbing material due to adhesion. The concentrated stress at the edge cannot be absorbed, and the vibration absorbing material has a problem that the efficiency of absorbing the vibration of the face plate is greatly reduced by the blocking of the adhesive layer. Thus, the structure of the conventional golf club head as described above must be further improved.

本発明はこのような問題点に鑑みて発明したものであって、その目的とするところは、フェース板の背面において熱圧または射出成形の方式により強化板を形成させ、強化板によりフェース板を支持することができると共に、フェース板と環状壁の境界に形成された結合端縁を完全に被覆することにより、打球の振動を吸収すると共に、応力の集中を減らすことができるため、構造の強度、振動吸収の効果、打球の性能とヘッドの使用寿命を高めることができるゴルフクラブヘッドの構造を提供しようとするものである。   The present invention has been invented in view of such problems, and the object of the present invention is to form a reinforcing plate on the back surface of the face plate by hot pressing or injection molding, and to form the face plate with the reinforcing plate.

図１、２、３を参照すると、本発明の実施例１のゴルフクラブヘッドの構造において金属、合金材質によりヘッド１が製成される。ヘッド１にはヘッド本体１０、フェース板１１、環状壁１２、ネック１３および強化板１５が含まれる。ヘッド本体１０の正面にはフェース板結合部１０１が形成されることにより、フェース板１１と結合することができる。フェース板１１は例えば嵌設、圧着、硬ろう付け、溶接、螺設などの方式によりヘッド本体１０のフェース板結合部１０１に結合することができ、または一体成形の方式によりヘッド本体１０に直接形成することができ、フェース板１１は打球するのに用いられることができる。環状壁１２はヘッド本体１０の周縁から後方へ延伸するように形成され、そして環状壁１２がヘッド本体１０の背面において囲むように開口部１２１が形成される。ネック１３はシャフト（図示せず）と結合するのに用いられる。強化板１５は開口部１２１の内部においてフェース板１１に緊密に貼り付けられ、そして強化板１５は全体として平板状に形成される。強化板１５は好ましくは熱圧または射出成形の方式により製成されるため、一体成形になるように直接フェース板１１の背面に緊密に結合される。強化板１５は軽質材料により製成され、例えばカーボン、樹脂（例えばエポキシ樹脂）、高分子化合材料、ゴムまたは軽質合金（例えばチタン合金、アルミ合金）およびその粘性複合粉末から選ぶことができる。また、ヘッド本体１０（フェース板１１を含まず）は使用上の需要性に応じて例えば精密鋳造、鋳造、機械加工、圧力鋳造、鍛造、射出成形などの方式により一体成形になるように製造したり、或いは分段接合の方式により一体になるように組み立てたりすることができる。   Referring to FIGS. 1, 2 and 3, in the structure of the golf club head according to the first embodiment of the present invention, the head 1 is made of metal or alloy material. The head 1 includes a head body 10, a face plate 11, an annular wall 12, a neck 13 and a reinforcing plate 15. A face plate coupling portion 101 is formed on the front surface of the head body 10 so that it can be coupled to the face plate 11. The face plate 11 can be coupled to the face plate coupling portion 101 of the head main body 10 by a method such as fitting, crimping, brazing, welding, and screwing, or directly formed on the head main body 10 by an integral molding method. The face plate 11 can be used for hitting a ball. The annular wall 12 is formed so as to extend rearward from the periphery of the head body 10, and an opening 121 is formed so that the annular wall 12 surrounds the back surface of the head body 10. The neck 13 is used to couple with a shaft (not shown). The reinforcing plate 15 is closely attached to the face plate 11 inside the opening 121, and the reinforcing plate 15 is formed in a flat plate shape as a whole. Since the reinforcing plate 15 is preferably manufactured by hot pressing or injection molding, it is directly bonded to the back surface of the face plate 11 so as to be integrally formed. The reinforcing plate 15 is made of a light material, and can be selected from, for example, carbon, resin (for example, epoxy resin), polymer compound material, rubber, light alloy (for example, titanium alloy, aluminum alloy), and viscous composite powder thereof. Further, the head main body 10 (not including the face plate 11) is manufactured so as to be integrally formed by a method such as precision casting, casting, machining, pressure casting, forging, injection molding or the like according to the usage demand. Or can be assembled so as to be united by a staged joining method.

再び図３を参照すると、強化板１５は熱圧または射出成形の方式を利用したため、粘着剤を使用して粘着することなく強化板１５をフェース板１１の背面に完全かつ緊密に結合することができる。強化板１５によりフェース板１１とヘッド本体１０の境界に形成された結合端縁１１１（例えば溶接路、ろう付けの溢材、嵌合位置または圧着位置）を完全に被覆することにより、打球時において強化板１５により結合端縁１１１の集中応力を吸収することができるため、結合端縁１１１が長期に渡って集中応力を受けた影響により亀裂が生じるのを避けることができると共に、さらにフェース板１１とヘッド１との結合の関係を強化してヘッド１の使用寿命を延ばすことができる。また、打球時において強化板１５によりフェース板１１が生じた振動を直接吸収することができる。その結果、ヘッド１は強化板１５により強度が最高となる構造で振動を吸収する効果を有すると共に、ヘッド１の打球の安定性と握り心地をさらに高めることができる。   Referring to FIG. 3 again, since the reinforcing plate 15 uses a hot press or injection molding method, the reinforcing plate 15 can be completely and tightly coupled to the back surface of the face plate 11 without using an adhesive. it can. By completely covering the connecting edge 111 (for example, welding path, brazing overflow material, fitting position or crimping position) formed at the boundary between the face plate 11 and the head body 10 by the reinforcing plate 15, Since the reinforcing plate 15 can absorb the concentrated stress of the coupling edge 111, it is possible to avoid the occurrence of cracks due to the influence of the concentrated stress on the coupling edge 111 over a long period of time, and the face plate 11 further. The service life of the head 1 can be extended by strengthening the connection relationship between the head 1 and the head 1. Further, the vibration generated by the face plate 11 by the reinforcing plate 15 at the time of hitting can be directly absorbed. As a result, the head 1 has the effect of absorbing the vibration with the structure having the highest strength by the reinforcing plate 15 and can further enhance the stability and gripping feeling of the hit ball of the head 1.

Compared to the first embodiment, in the third embodiment, a deformation hole 152 is formed in the reinforcing plate 15, and the deformation hole 152 is provided so as to correspond to the position of the back surface of the main striking zone of the face plate 11. Accordingly, the main hit zone of the face plate 11 is formed by the deformation hole 152 so as to have the maximum elastic deformation at the time of hitting, so that the hit distance of the hit ball can be increased. Further, the reinforcing plate 15 can enhance the coupling strength between the face plate 11 and the head body 10 and the absorption of vibrations when hitting the ball, and can support the face plate 11.

図９、１０を参照すると、本発明の実施例４のゴルフクラブヘッドの構造が掲示される。実施例２と比較し、実施例４においては強化板１５には延伸部１５１が形成されるだけではなく、さらに強化板１５には変形孔１５２が形成される。変形孔１５２は同様にフェース板１１の主な打撃ゾーンの背面の位置に対応するように設けられる。これにより、打球時において変形孔１５２によりフェース板１１の主な打撃ゾーンは最大な弾性による変形を有するように形成されるため、打球の飛距離を増やすことができる。また、強化板１５と延伸部１５１によりフェース板１１とヘッド本体１０の結合強度および打球時の振動の吸収を高めることができると共に、フェース板１１を支持することができる。   9 and 10, the structure of the golf club head according to the fourth embodiment of the present invention is posted. Compared with the second embodiment, in the fourth embodiment, not only the stretched portion 151 is formed in the reinforcing plate 15 but also the deformation hole 152 is formed in the reinforcing plate 15. Similarly, the deformation hole 152 is provided so as to correspond to the position of the back surface of the main striking zone of the face plate 11. Accordingly, the main hit zone of the face plate 11 is formed by the deformation hole 152 so as to have the maximum elastic deformation at the time of hitting, so that the hit distance of the hit ball can be increased. Further, the reinforcing plate 15 and the extending portion 151 can increase the coupling strength between the face plate 11 and the head main body 10 and the absorption of vibration at the time of hitting the ball, and can support the face plate 11.

図１１、１２を参照すると、本発明の実施例５のゴルフクラブヘッドの構造が掲示される。実施例２と比較し、実施例５においては環状壁１２は開口部１２１の内側へ内径方向に向かって延伸するように環状フランジ１２２が形成される。これにより、熱圧または射出成形の方式により強化板１５と延伸部１５１が形成された時、延伸部１５１の末端は直接環状フランジ１２２の内側に緊密に結合されることができるため、環状フランジ１２２により強化板１５と延伸部１５１を制限することにより、強化板１５と延伸部１５１が外へ向かってヘッド１の開口部１２１から離脱するのを避けることができる。フェース板１１が打球の応力を受けた時、環状フランジ１２２は延伸部１５１に緊密に当接するように形成されるため、強化板１５によりフェース板１１を支持する効果を高めることができる。   11 and 12, the structure of the golf club head according to the fifth embodiment of the present invention is posted. Compared with the second embodiment, in the fifth embodiment, an annular flange 122 is formed so that the annular wall 12 extends toward the inside of the opening 121 in the inner diameter direction. As a result, when the reinforcing plate 15 and the extending portion 151 are formed by hot pressing or injection molding, the end of the extending portion 151 can be tightly coupled directly to the inside of the annular flange 122. By restricting the reinforcing plate 15 and the extending portion 151, it is possible to avoid the reinforcing plate 15 and the extending portion 151 from detaching from the opening 121 of the head 1 toward the outside. When the face plate 11 is subjected to hitting stress, the annular flange 122 is formed so as to be in close contact with the extending portion 151, so that the effect of supporting the face plate 11 with the reinforcing plate 15 can be enhanced.

図１３、１４を参照すると、本発明の実施例６のゴルフクラブヘッドの構造が掲示される。実施例２と比較し、実施例６においてはヘッド１には環状フランジ１２２と変形孔１５２が形成されるだけではなく、さらに強化板１５の延伸部１５１には複数個の凹欠部１５３が形成される。凹欠部１５３は例えば適当な規格を有した半円形、半楕円形、三角形、方形、渦巻き形、水滴形などの幾何形状に形成されることができる。これにより、凹欠部１５３により上述の構造強化、振動吸収と支持効果に影響を及ぼさない状態で軽質材料の用量をさらに減らすことができると共に、ヘッド１の背面の外観的な視覚効果を相対的に増やすことができる。   13 and 14, the structure of the golf club head according to the sixth embodiment of the present invention is posted.
