Abstract
Description
- 1. Field of the Invention
- The invention relates to a golf club head, more particularly to a golf club head with high strength and lightweight properties.
- 2. Description of the Related Art
- Referring to
FIGS. 1 and 2 , a conventionalgolf club head 2 includes a frontstriking portion 22, anupper shell portion 23 formed as one piece with the frontstriking portion 22 and cooperating with the frontstriking portion 22 to define alower opening 20, and alower shell portion 21 fitted in thelower opening 20. Both of theupper shell portion 23 and the frontstriking portion 22 are formed with reinforcingribs 24 projecting inwardly therefrom so as to reinforce the mechanical strength of thegolf club head 2 while reducing the thickness of theupper shell portion 23 and the frontstriking portion 22 to reduce the overall weight of thegolf club head 2. - Since the
upper shell portion 23 and the frontstriking portion 22 are made of metal, the weight thereof cannot be reduced effectively. Moreover, since the frontstriking portion 22 is provided with the reinforcingribs 24, the center of gravity of thegolf club head 2 is located at a distance relatively proximate to the frontstriking portion 22, which in turn reduces the striking stability and the striking distance. - Therefore, the object of the present invention is to provide a golf club head which possesses high strength and lightweight properties.
- Accordingly, the golf club head of this invention includes a hollow head body having a front striking member, an upper shell portion extending rearwardly from the front striking member, and a lower shell portion extending rearwardly from the front striking member and connected to the upper shell portion. The upper and lower shell portions and the front striking member cooperatively confine an enclosed inner space. One of the upper and lower shell portions is made of plastic, and the other one of the upper and lower shell portions is made of metal. The plastic shell portion has an inner surface, and a plurality of reinforcing ribs projecting from the inner surface. The front striking member has a rear inner surface which is free of the reinforcing ribs projecting therefrom. By virtue of the reinforcing ribs on the plastic shell portion, the distance of the center of gravity of the hollow head body from the front striking member can be increased.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
-
FIG. 1 is an exploded perspective view of a conventional golf club head; -
FIG. 2 is a sectional view of the conventional golf club head; -

FIG. 9 is a schematic view of the fifth preferred embodiment. - Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
- Referring to
FIGS. 3 and 4 , the first preferred embodiment of a golf club head according to this invention is shown to include a hollow head body 1 having a frontstriking member 12, anupper shell portion 13 extending rearwardly from the frontstriking member 12, and alower shell portion 11 extending rearwardly from the frontstriking member 12 and connected to theupper shell portion 13. The upper andlower shell portions striking member 12 cooperatively confine an enclosed inner space. In this embodiment, theupper shell portion 13 is made of plastic. Preferably, theupper shell portion 13 is made of carbon fibers. Moreover, in this embodiment, thelower shell portion 11 is made of metal. Theupper shell portion 13 has aninner surface 131, and a plurality of reinforcingribs 14 projecting from theinner surface 131. The frontstriking member 12 has a rearinner surface 121 which is free of the reinforcingribs 14 projecting therefrom. By virtue of the reinforcingribs 14 on theupper shell portion 13, the distance of the center of gravity of the hollow head body 1 from the frontstriking member 12 can be increased. In other wards, the center of gravity of the hollow head body 1 can be shifted rearwardly from the frontstriking member 12 compared to that of the conventionalgolf club head 2 so that the striking stability and the striking distance can be improved. The reinforcingribs 14 are provided at a distance of at least 2 cm from the frontstriking member 12, are parallel to each other, and are straight. Therefore, the distance of the center of gravity of the hollow head body 1 from the frontstriking member 12 can be increased. In this preferred embodiment, theupper shell portion 13 and the reinforcingribs 14 are made of plastic, and the reinforcingribs 14 are formed as one piece with theupper shell portion 13. - When making the golf club head of this embodiment, the
upper shell portion 13 is formed as one piece with the reinforcingribs 14 by any suitable manner, such as molding, from carbon fibers. Theupper shell portion 13 is then assembled with thelower shell portion 11 and the frontstriking member 12 by any suitable manner well known in the art to form the golf club head. - Alternatively, the reinforcing
ribs 14 can be made of a material different from that of theupper shell portion 13, and are assembled to theupper shell portion 13 by any suitable manner, such as gluing or anchoring. For example, the reinforcingribs 14 can be made of a metal material, and theupper shell portion 13 is made of carbon fibers. - In view of the aforesaid, the golf club head of this embodiment has the following advantages:
- 1. Since the
upper shell portion 13 of the golf club head is made of carbon fibers, the total weight of the golf club head can be reduced. On the other hand, since theupper shell portion 13 is provided with a plurality of reinforcingribs 14 projecting from theinner surface 131 thereof, the mechanical strength can be increased as well while reducing the total weight of the golf club head. - 2. Since the reinforcing
ribs 14 are provided at a distance distal from the frontstriking member 12, i.e., at a distance of at least 2 cm from the frontstriking member 12, the distance of the center of gravity of the hollow head body 1 from the frontstriking member 12 can be increased. Therefore, the striking stability and the striking distance can be improved accordingly. - 3. The sound wave produced inside the hollow head body 1 while striking a golf ball can be destroyed by the reinforcing
ribs 14. Therefore, the striking sound is relatively crisp. - Referring to
FIG. 5 , the second preferred embodiment of a golf club head according to this invention is similar to the first preferred embodiment except that the reinforcingribs 14 are straight and extend along intersecting lines. - Referring to
FIG. 6 , the third preferred embodiment of a golf club head according to this invention is similar to the first preferred embodiment except that the reinforcingribs 14 are cured. - Referring to
FIG. 7 , the fourth preferred embodiment of a golf club head according to this invention is similar to the second preferred embodiment except that the reinforcingribs 14 are curved. - Referring to
FIGS. 8 and 9 , the fifth preferred embodiment of a golf club head according to this invention is similar to the first preferred embodiment except that thelower shell portion 11 and the reinforcingribs 14 are made of plastic, and that the reinforcingribs 14 project from thelower shell portion 11. In the fifth preferred embodiment, the reinforcingribs 14 are formed as one piece with thelower shell portion 11. Alternatively, the reinforcingribs 14 can be made of a material different from that of thelower shell portion 11, and are assembled to thelower shell portion 11 by any suitable manner, such as gluing or anchoring. For example, the reinforcingribs 14 can be made of a metal material, and thelower shell portion 11 is made of carbon fibers. - While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
