Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a golf club head. More particularly, the present invention relates to a golf club head with a club portion and a main body made of different materials.

[0003] 2. Description of the Related Art

[0004] FIG. 1A is a schematic exploded view of a conventional golf club head, and FIG. 1B is a schematic combined view of the conventional golf club head. Referring to FIGS. 1A and 1B, the conventional golf club head 1 comprises a main body 11 and a hitting plate 12. The main body 11 is integrally formed and has a notch 111 and a club portion 112. The shape of the hitting plate 12 matches with the shape of the notch 111, and then, the hitting plate 12 and the notch 111 are jointed together through welding, brazing, or other mechanical jointing manners.

[0005] Generally, in conventional manufacturing process, the main body 11 having the club portion 112 is integrally formed by the same material such as stainless steel, carbon steel, or alloy, etc. The prices of these materials are usually expensive. Therefore, the manufacturing cost is relatively high for the conventional golf club head 1. In addition, the main body 11 is integrally formed by the same material with a high rigidity. With the high rigidity material, it is not only quite difficult to adjust the angle between the club portion 112 and the hitting plate 12 but also easily results in the crack and damage of the main body 11.

[0006] In addition, the main body 11 made of a material with a higher rigidity may also cause the golf club head 1 to have a poorer damping effect and a lower coefficient of rebound, and as a result, the hitting effect is reduced and the golfer has a poor hitting sense.

[0007] Consequently, there is an existing need for providing a golf club head to solve the above-mentioned problems.

SUMMARY OF THE INVENTION

[0008] The present invention is directed to a golf club head, which comprises a main body and a club portion. The main body has a first junction surface, and the main body is made of a first material. The club portion has a second junction surface, the second junction surface is used to be jointed with the first junction surface, and the club portion is made of a second material. The second material and the first material are substantially different materials.

[0009] As compared with the first material, the second material has a higher ductility, so after the main body and the club portion are jointed together, the club portion has the function of adjusting the angle, and the golf club head has a preferred damping effect and a high coefficient of rebound. Furthermore, the golf club head is formed by the main body and the club portion made of different materials, which can solve the problem that the integrally-formed main body and the club portion of the conventional golf club head must be manufactured with plenty of expensive material, and thus reducing the manufacturing cost.

DETAILED DESCRIPTION OF THE INVENTION

[0018] FIG. 2A is a schematic exploded view of a golf club head according to a first embodiment of the present invention, and FIG. 2B is a schematic combined view of the golf club head according to the first embodiment of the present invention. Referring to FIGS. 2A and 2B, the golf club head 2 of the first embodiment comprise a main body 21 and a club portion 22.

[0019] The main body 21 has a first junction surface 211, and the main body 21 is made of a first material. The club portion 22 has a second junction surface 211, the second junction surface 221 is used to be jointed with the first junction surface 211, and the club portion 22 is made of a second material. The second material and the first material are substantially different materials. Preferably, as compared with the first material, the second material has a higher ductility. The first junction surface 211 and the second junction surface 221 are jointed together by three-dimensional (3D) welding. In other applications, the first junction surface 211 and the second junction surface 221 may be jointed by brazing, soldering, bonding, or friction stir welding.

[0020] In the first embodiment, the main body 21 is integrally formed and has a hitting surface 212, wherein the first material of the main body 21 is a stainless steel or a titanium alloy, and the main body 21 is formed by casing, forging, or machining. The second material of the club portion 22 is a soft iron, a cast iron, or a Fe/Mn/Al alloy, and the club portion 22 is formed by casing, forging, or machining.

[0021] It should be noted that, in the first embodiment, the golf club head 2 is an iron head, and in other applications, the golf club head 2 may also be a putter head or a wood head (as shown in FIG. 3).

[0022] The second material has a higher ductility than the first material, so after the main body 21 and the club portion 22 are jointed together, the club portion 22 has the function of adjusting the angle, and the golf club head 2 has a preferred damping effect and a high coefficient of rebound. Furthermore, the golf club head 2 is formed by the main body 21 and the club portion 22 made of different materials, so as to solve the problem that the integrally-formed main body and the club portion of the conventional golf club head must be manufactured with plenty of expensive material (for example, Fe/Mn/Al alloy), and to reduce the manufacturing cost.

[0023] Preferably, the golf club head 2 further comprises at least one weighting structure (not shown). The weighting structure is disposed in the main body 21, for example, the weighting structure is disposed at the bottom or at the back of the main body 21. The weighting structure may be a W/Ni alloy, a tungsten rubber, or a weighting screw, which is formed by casting, forging, machining, or power metallurgy. Through the weighting structure, the center of gravity of the golf club head 2 may be further adjusted (for example, the center of gravity is lowered), and thus the hitting effect of the golf club head 2 is further enhanced.

[0024] FIG. 4A is a schematic exploded view of a golf club head according to a second embodiment of the present invention, and FIG. 4B is a schematic combined view of the golf club head according to the second embodiment of the present invention. Referring to FIGS. 4A and 4B, a golf club head 3 of the second embodiment has a main body 31 and a club portion 32. The difference between the golf club head 3 of the second embodiment and the golf club head 2 of the first embodiment of FIG. 2A is that the main body 31 comprises a main portion 311 and a hitting plate 312, the main portion 311 has a notch 313, the shape of the hitting plate 312 matches with the shape of the notch 313, and the hitting plate 312 is disposed on the notch 313.

[0025] The main portion 311 is made of the stainless steel or titanium alloy, and the hitting plate 312 is made of titanium alloy, stainless steel, Fe/Mn/Al alloy or aluminum alloy. The main portion 311 and the hitting plate 312 are formed by casting, forging, or machining. In the second embodiment, the main portion 311 and the hitting plate 312 are jointed by 3D welding, or they may be jointed together by welding, brazing, soldering, bonding, or friction stir welding.

[0026] It should be noted that, in the second embodiment, the golf club head 3 is an iron head, and in other applications, the golf club head 3 may also be a putter head or a wood head (as shown in FIG. 5).

[0027] The club portion 32 (the second material) of the golf club head 3 in the second embodiment has a higher ductility as compared with the main portion 311 and the hitting plate 312 (the first material), so that the club portion 32 has the function of adjusting the angle. Similar to the golf club head 2 of the first embodiment, the golf club head 3 of the second embodiment also has the preferred damping effect and high coefficient of rebound, and the manufacturing cost can be reduced.

[0028] While the embodiments of the present invention have been illustrated and described, various modifications and improvements can be made by those skilled in the art. The embodiments of the present invention are therefore described in an illustrative but not restrictive sense. It is intended that the present invention may not be limited to the particular forms as illustrated, and that all modifications that maintain the spirit and scope of the present invention are within the scope as defined in the appended claims.
