The specific embodiment
Below, with reference to accompanying drawing formation of the present invention is described in detail.
What Fig. 1 (a)～Fig. 1 (c) represented is the glof club head that is made of embodiment of the present invention.Shown in Fig. 1 (a)～Fig. 1 (c), that the glof club head of the present embodiment possesses is facial with forming, the metal case member 11 of bottom and neck and the case member 21 that forms the fibre reinforced plastics system of bizet engage and the bar head main body 1 of the hollow structure that forms.
In above-mentioned hollow golf club head, position of centre of gravity can be at random set in combination based on different kinds material, or it is long-pending to increase rod head body in confined quality as much as possible, can improve the golf clubs performance that comprises flying distance and directionality thus,, because just metal case member 11 is overlapped with the case member 21 of fibre reinforced plastics system bonding, its bond strength is insufficient.Therefore, in the present invention, with joint form as described below, the case member of compound these different kinds materials in high strength ground.
In the joint form of Fig. 2 (a) and Fig. 2 (b), the junction surface 21a of the case member 21 of fibre reinforced plastics system is bonded on the two sides of junction surface 11a of metal case member 11 with being divided into two forks.That is, the forked junction surface 21a of case member 21 is seized on both sides by the arms on the 11a of the junction surface of case member 11.According to above-mentioned joint form, because make the bond area increase, so can access sufficient durability as glof club head by the two sides is bonding.
In the joint form of 3 (a) and Fig. 3 (b), the junction surface 21a of the case member 21 of the fibre reinforced plastics system of making is bonded on the two sides of junction surface 11a of metal case member 11 with being divided into two forks, and the wall thickness of junction surface 11a that makes metal case member 11 is to end attenuation gradually.According to above-mentioned joint form, because by in the bonding increase bond area in two sides, can also avoid concentrating, so can access sufficient durability as glof club head to the stress of the end face of junction surface 11a.
In the joint form of Fig. 4 (a) and Fig. 4 (b), the junction surface 21a of the case member 21 of the fibre reinforced plastics system of making is bonded on the two sides of junction surface 11a of metal case member 11 with being divided into two forks, and offers the otch 12 of several broach shapes on the 11a of the junction surface of metal case member 11.For this reason, the fibre reinforced plastics of case member 21 also fill in this otch 12, according to above-mentioned joint form, because and processing broach bonding by the two sides increase bond area, so can access the sufficient durability as glof club head.
In the engagement state of Fig. 5 (a) and Fig. 5 (b), the junction surface 21a of the case member 21 of the fibre reinforced plastics system of making is bonded on the two sides of junction surface 11a of metal case member 11 with being divided into two forks, and offers through hole 13 on the 11a of the junction surface of metal case member 11.For this reason, the fibre reinforced plastics of case member 21 also fill in this through hole 13.According to above-mentioned joint form, because the processing of bonding and hole increases bond area by the two sides, so can access sufficient durability as glof club head.
In the joint form of Fig. 6 (a) and Fig. 6 (b), the junction surface 21a of the attachment 21 of fibre reinforced plastics system is bonded on the junction surface 11a of metal case member 11, and offer several through holes 13 on the junction surface 11a of metal case member 11, pass the suture material 22 of fibre reinforced plastics system in this through hole 13, by the case member 21 and the metal case member 11 of these suture material 22 binding fiber reinforced plastics systems.According to above-mentioned joint form, because suture material 22 makes the case member 21 of fibre reinforced plastics system link securely with respect to metal case member 11, so can access sufficient durability as glof club head.In addition, case member 21 and suture material 22 have good mutual cementability because being all plastics, even if so only be bonding as shown in figure also passable, if but make suture material 22 go back the case member 21 of perforating fiber reinforced plastics system, the adhesion of machinery then can further be obtained.
As the material of case member 11, can use metals such as titanium alloy, aluminium alloy, stainless steel.
Material as case member 21, the fibre reinforced plastics that can use matrix resins such as epoxy resin, unsaturated polyester resin, vinyl ester resin to soak in the fortifying fibres such as being contained in carbon fiber, glass fibre, aramid fibre and form particularly are preferably carbon fiber as fortifying fibre.
In addition, in order further to improve the bond strength of metal case member 11 and the case member 21 of fibre reinforced plastics system, the junction surface 11a of metal case member 11 is preferably and makes surface roughness by attrition process etc. is 0.5～2.0.
In above-mentioned embodiment, be that the metal case member of, bottom facial at constituting and neck and the case member that constitutes the fibre reinforced plastics system of bizet engage and formed the explanation that the situation of the bar head main body of hollow structure is carried out, do not limit but the shared part of case member of shared part of metal case member and fibre reinforced plastics system is special on the bar head main body in the present invention.
Example
Engage and constituted the hollow golf club head of the bar head main body of hollow structure for case member, made making it engage form all different comparative examples 1 (known technology) and embodiment 1～5 are arranged respectively metal case member and fibre reinforced plastics system.
To these glof club heads, estimate the durability at its junction surface, its result is presented in the table 1.Evaluation result is to represent comparative example 1 as 100 index.About the durability at junction surface, the big more durability that means of exponential quantity is good more.
Table 1
| The structure at junction surface | The durability at junction surface | |
| Comparative example 1 | Bonding FRP on the single face of metal part | 100 |
| Embodiment 1 | Bonding FRP (Fig. 2) on the two sides of metal part | 110 |
| Embodiment 2 | Bonding FRP+ wall thickness change (Fig. 3) on the two sides of metal part | 115 |
| Embodiment 3 | Bonding FRP+ otch (Fig. 4) on the two sides of metal part | 114 |
| Embodiment 4 | Bonding FRP+ through hole (Fig. 5) on the two sides of metal part | 113 |
| Embodiment 5 | Perforation+suture material (Fig. 6) is arranged on metal part | 121 |
As the judgement according to this table 1, the glof club head of embodiment 1～5 any one and comparative example 1 compare, and the durability at junction surface all is better than comparative example 1.
According to the present invention, at the case member of the case member of jointing metal system and fibre reinforced plastics system and when constituting the bar head main body of hollow structure, since be in the mode on two sides that fibre reinforced plastics are crossed on the junction surface of metal case member two case members are carried out bonding, so can improve the bond strength of the case member of metal case member and fibre reinforced plastics system.Thereby in the durability of guaranteeing as glof club head, can also improve the golf clubs performance that comprises flying distance and directionality based on the combination of different kinds material.
More than, the just explanation of carrying out at embodiment preferred of the present invention, but be appreciated that in the spirit of the present invention and scope that do not break away from by additional technical scheme defined, can carry out relative therewith all changes, use and replace.
