Abstract
A golf club head for an iron includes a back part, a striking plate covering the back part, and a fixing unit to join the striking plate and the back part. The fixing unit has a looped groove provided between the striking plate and the back part, and a welding material interconnecting the striking plate and the back part and filled in the looped groove.
Description
- 1. Field of the Invention
- This invention relates to a golf club head, more particularly to a golf club head that can be connected fixedly to a bottom end of a shaft of an iron.
- 2. Description of the Related Art
- Golf clubs are grouped into three categories according to their functions: (1) Woods for long shots, (2) Irons for middle distance shots, and (3) Putters for aiming a golf ball into a hole. The structure of each golf club generally includes a shaft, and a head fixed to a bottom end of the shaft and having a striking plate for striking a golf ball.
- Referring to
FIGS. 1 and 2 , a conventionalgolf club head 1 for an iron includes aback part 11 having acavity 112 and aperipheral end face 111, astriking plate 12 covering theback part 11 and having aback face 121 abutting against theperipheral end face 111, a vibration-absorbingelement 13 disposed in thecavity 112, and abrazing filler metal 14 to join thestriking plate 12 and theback part 11. - To assemble the conventional
golf club head 1, thestriking plate 12 is first placed over theback part 11 so that theback face 121 abuts against theperipheral end face 111, after which thestriking plate 12 and theback part 11 are pressed together. Thebrazing filler metal 14 is then put around a joint between theend face 111 and theback face 121, and is heated so as to be formed into a molten material. The moltenbrazing filler metal 14 flows into a clearance between theend face 111 and theback face 121 through a capillary action. When the moltenbrazing filler metal 14 solidifies, thestriking plate 12 is welded fixedly to theback part 11. - Since the
end face 111 and theback face 121 have flat surfaces, when they abut against each other, the clearance therebetween is relatively small. Hence, during brazing, only a minimal amount of the moltenbrazing filler metal 14 seeps into the clearance between theend face 111 and theback face 121, thereby resulting in the formation of an incomplete brazing layer and a weak brazing connection between thestriking plate 12 and theback part 11. Further, after going through several ball-striking actions, the incomplete brazing layer may crack and thereby lead to separation of thestriking plate 12 from theback part 11. Because of these reasons, during brazing, an operator must wait a considerable time so as to allow thebrazing filler metal 14 to fill completely the clearance between theend face 111 and theback face 121. Even so, the ideal brazing connection is difficult to obtain. Moreover, the operator usually applies a large amount of thebrazing filler metal 14 around the joint between theend face 111 and theback face 121 in an effort to increase the amount of thebrazing filler metal 14 that seeps into the clearance. However, when thebrazing filler metal 14 is cooled and solidified, thebrazing filler metal 14 becomes a protruding body, which affects not only the appearance of thegolf club head 1, but also the effect of striking a golf ball, so that another finishing process has to be performed. - Therefore, the object of the present invention is to provide a golf club head for an iron that is capable of overcoming the aforementioned drawbacks of the prior art.
- According to this invention, a golf club head for an iron comprises a back part, a striking plate covering the back part, and a fixing unit to join the striking plate and the back part. The fixing unit has a looped groove provided between the striking plate and the back part, and a welding material interconnecting the striking plate and the back part and filled in the looped groove.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments of the invention, with reference to the accompanying drawings, in which:
-

back part 2 is a metal shell, and includes acavity 22, and atubular wall 23 extending around thecavity 22 and havingperipheral end face 21. - The
striking plate 3 is a metal plate covering theback part 2, and has aback face 31 abutting against theperipheral end face 21, and astriking face 32 opposite to theback face 31 for striking a golf ball (not shown). Aneck 33 extends upwardly and integrally from a top end of thestriking plate 3 to connect fixedly with a shaft of the iron (not shown). Alternatively, theneck 33 may be formed integrally with theback part 2. The configuration of theneck 33 is not limited to the disclosed embodiment. - The shock-absorbing
element 5 is disposed in thecavity 22 to absorb vibration during striking of the golf ball. Since the structure and material of the shock-absorbingelement 5 are not important aspects of the present invention, and the shock-absorbingelement 5 may be dispensed with, it is not described in detail herein. - The
fixing unit 6 is provided to join thestriking plate 3 and theback part 2, and has a loopedgroove 61 formed between theperipheral end face 21 of theback part 2 and theback face 31 of thestriking plate 3 and extending along the length of theperipheral end face 21, and a welding material interconnecting thestriking plate 3 and theback part 2 and filled in thelooped groove 61. The welding material in this embodiment is abrazing filler metal 62 that has a melting point lower than those of theback part 2 and thestriking plate 3. Further, in this embodiment, theend face 21 is indented to form the loopedgroove 61, and the loopedgroove 61 has a substantially U-shaped cross section. Alternatively, the cross section of the loopedgroove 61 may be V-shaped, square-shaped, or formed into any other geometrical configuration. Hence, the shape of the loopedgroove 61 is not limited to the disclosed embodiment. - To assemble the
