PURPOSE:To enable to disperse localised concentration of stress caused by impact at the time of hitting ball on a shaft which is inserted in and fixed to a part of a head-hosel part and simultaneously to enable to improve durability by preventing breakage of shaft and enhance as well each strength of junction. CONSTITUTION:Bar-like materials for core part 10 is inserted and secured in an insertion hole 3 on a hosel part 2 of a head main body 1. An upper end part 10a of this bar-like material for core part 10 is made protruted from a hosel part 2. A tip part 5 of a shaft main body 4 is made inserted and held between insertion hole for a shaft 3 and material for core part 10.
【産業上の利用分野】この発明は、例えばウッドクラブヘッドあるいはアイアンクラブなどのクラブヘッドのネック部を形成するホーゼル部へのシャフトの接合構造に改良を施したゴルフ用クラブに関し、特にヘッド本体ホーゼル部のシャフト挿着孔と、このシャフト挿着孔に挿入されて固着されるシャフトのチップ部との剛性差を低減して、打球時の衝撃によるシャフトのチップ部への局部的な応力の集中を分散化させ、これによって、シャフトの折損を防止するとともに、互いの接合強度を高めることにより、耐久性の向上を図るようにしたものである。 BACKGROUND OF THE INVENTION This invention, for example, relates club golf subjected to improved bonding structure for the shaft of the hosel portion forming the neck portion of the club head, such as wood club head or iron club, especially head body hosel a shaft insertion hole parts, by reducing the difference in rigidity between the tip portion of the shaft is secured is inserted into the shaft insertion hole, local concentration of stress to the chip portion of the shaft due to the impact of hitting was dispersed, thereby, possible to prevent the breakage of the shaft by increasing the bonding strength of each other, it is obtained as to improve the durability.
【従来の技術】従来、この種のゴルフ用クラブ、例えばウッドクラブにおいては、図４に示すように、ヘッド本体１のネック部１ａを一体に形成する肉厚が等厚なホーゼル部２に、シャフトシャフト挿着孔３を設け、このシャフト挿着孔３内にテーパパイプ状をなすシャフト本体４の先細端部側チップ部５を挿入し、このシャフト本体４のチップ部５の外周面５ａとシャフト挿着孔３の内周面３ａとの間に充填される接着剤層６を介して互いに固着してなる構成となっている。 Conventionally, golf club of this kind, for example in the wood clubs, as shown in FIG. 4, the hosel 2 thick is equal thickness to form the neck portion 1a of the head body 1 integrally, the provided shaft shaft insertion hole 3, and inserting the end portion side tip portion 5 tapered shaft body 4 forming a Tepapaipu shape to the shaft insertion hole 3, an outer circumferential surface 5a and the shaft of the tip portion 5 of the shaft body 4 and has a fixed and formed by arrangement with each other via an adhesive layer 6 which is filled between the inner peripheral surface 3a of the insertion hole 3.
【０００３】また、前記ヘッド本体ホーゼル部２のシャフト挿着孔３開口端側の端面２ａとシャフト本体チップ部５の外周面５ａとの接合部位には、ヘッド本体ホーゼル部２の肉厚の等厚によって、それらの間に生じる段差を吸収するために、例えばセルロイド等のプラスチック製のフェルール（保護キャップ）７を装着している。 [0003] Also, the bonding portion between the outer peripheral surface 5a of the head body hosel second shaft insertion hole 3 end surface 2a of the opening end side and the shaft main chip portion 5, the thickness of the head body hosel 2 equal the thickness, in order to absorb the level difference caused between them, for example wearing the plastic ferrule (protective cap) 7 such as celluloid.
【発明が解決しようとする課題】しかしながら、上記した従来構造のゴルフ用クラブにあっては、ヘッド本体ホーゼル部２の端面２ａとフェルール７との境界部ａに対応するシャフトの部位に、打球時の衝撃によって発生する大きな応力が局部的に集中し、この部位での座屈あるいは圧縮破壊によってシャフトの折損が発生し、特に、 [SUMMARY OF THE INVENTION However, in the golf club having a conventional structure described above, a portion of the shaft corresponding to the boundary portion a between the end surface 2a and the ferrule 7 of the head main body hosel portion 2, when hitting large stress generated by the impact is concentrated locally, breakage of the shaft is generated by the buckling or compression fracture at this site, in particular,
このようなシャフトの折損は、ヘッド本体１のネック部１ａの長さを短くしてなるショートネック型のクラブヘッドや軽量シャフトなどにおいて生じ易い。 Breakage of such shaft is likely to occur in such a short neck type club head and weight shaft formed by shortening the length of the neck portion 1a of the head body 1.
【０００５】しかも、ショートネック型のクラブヘッドでは、ヘッド本体１のホーゼル部２とシャフト本体４との間の接合面積が小さいことから、互いの接合強度が低く、打球時の衝撃で接着剤層６が破壊して、ヘッド抜けが発生し易く、耐久性に劣るばかりでなく、危険性を伴うという問題があった。 [0005] Moreover, in the short-neck of the club head, since the bonding area between the hosel portion 2 and the shaft body 4 of the head body 1 is small, the bonding strength of each other is low, the adhesive layer by an impact produced when hitting the ball 6 is destroyed, easy head omission has occurred, not only inferior in durability, there is a problem that involves a risk.
【発明の目的】この発明の目的は、ヘッドホーゼル部に挿着されるシャフトへの打球時の衝撃による局部的な応力の集中を分散化させ、シャフトの折損を防止するとともに、互いの接合強度を高めて、耐久性の向上を図ることができるようにしたゴルフ用クラブを提供することにある。 SUMMARY OF THE INVENTION An object of the invention is dispersed the local concentration of stress due to the impact of hitting to the shaft to be inserted into Heddohozeru unit, it is possible to prevent breakage of the shaft, the bonding strength of each other the enhancing is to provide a club golf that to be able to improve the durability.
【課題を解決するための手段】上記した課題を解決するために、この発明は、ヘッド本体のネック部を形成するホーゼル部に設けたシャフト挿着孔に、パイプ状のシャフト本体のチップ部を挿入してなるゴルフ用クラブにおいて、前記ヘッド本体ホーゼル部のシャフト挿着孔内に棒状芯部材を挿通させて設け、かつ該棒状芯部材の上端部を前記ホーゼル部から突出させるとともに、前記シャフト挿着孔と前記棒状芯部材との間に、前記シャフト本体のチップ部を挿入保持させてなる構成としたものである。 In order to solve the aforementioned problems SUMMARY OF THE INVENTION This invention relates to a shaft insertion hole formed in the hosel portion forming the neck portion of the head body, the tip portion of the pipe-shaped shaft body in the inserted golf club comprising, by inserting the rod-like core member is provided, and are made to protrude from the upper end of the rod-shaped core member from the hosel part to the head main body hosel portion of the shaft insertion hole, the shaft interpolation between the bar-like core member and Chakuana is obtained by a structure comprising inserted to hold the tip portion of the shaft body.
