GOLF CLUB HEAD
A golf club head includes a metal head body and a non-metal tubular member. The metal head body includes a hollow body portion having a bottom plate, and a neck connected integrally to the hollow body portion and opposite to the bottom plate. The neck has an outer open end, and an integral inner tubular part extending into the hollow body portion from the outer open end. The non-metal tubular member extends within the hollow body portion, and has a top portion connected to the neck and a bottom portion connected to the bottom plate of the hollow body portion.
1. Field of the Invention
The invention relates to a golf club head, more particularly to a golf club head, the center of gravity of which is lowered.
2. Description of the Related Art
A conventional method for fabricating a golf club head includes a front processing stage and a rear processing stage. The front processing stage involves precision casting technology, and includes the steps of mold-making, wax injection, hanging, dipping, dewaxing, casting, cutting, heat treating, etc. A golf club head blank made via the front processing stage is further processed via the rear processing stage, which is a semi-automatic mechanical processing technique, and which includes the steps of surface grinding, washing, lacquering, punching, embedding, assembling, torque testing, polishing, etc., so as to obtain a golf club head product.
Referring to
Therefore, the object of the present invention is to provide a golf club head, which can be made relatively easily, and the center of gravity of which is lowered effectively.
Accordingly, in one aspect of this invention, a golf club head includes a metal head body and a non-metal tubular member. The metal head body includes a hollow body portion having a bottom plate, and a neck connected integrally to the hollow body portion and opposite to the bottom plate. The neck has an outer open end, and an integral inner tubular part extending into the hollow body portion from the outer open end. The non-metal tubular member extends within the hollow body portion, and has a top portion connected to the neck and a bottom portion connected to the bottom plate of the hollow body portion.
In another aspect of this invention, a golf club includes a golf club head and a shaft. The golf club head includes a metal head body and a non-metal tubular member. The metal head body includes a hollow body portion having a bottom plate, and a neck connected integrally to the hollow body portion and opposite to the bottom plate. The neck has an outer open end, and an integral inner tubular part extending into the hollow body portion from the outer open end. The non-metal tubular member extends within the hollow body portion, and has a top portion connected to the neck and a bottom portion connected to the bottom plate of the hollow body portion. The shaft has an end portion extending fittingly into the non-metal tubular member.
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:
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
In making the golf club head 2, the non-metal tubular member 22 is positioned in a wax mold (not shown) for making a blank of the metal head body 21. A front processing stage, which includes the steps of mold-making, wax injection, hanging, dipping, dewaxing, casting, cutting, heat treating, etc, is then proceeded to make a semi-product of the golf club head 2 composed of the non-metal tubular member 22 and the blank of the metal head body 21. The semi-product further undergoes a rear processing stage, which includes the steps of surface grinding, washing, lacquering, punching, embedding, assembling, torque testing, polishing, etc., to obtain the golf club head 2.
The non-metal tubular member 22 cooperates with the inner tubular part 212 of the neck 210 to define a receiving space 216 for fitting a lower end portion 41 of the shaft 4 thereinto.
In view of the aforesaid, the non-metal tubular member 22 is provided separately, and is bonded to the metal head body 21 after casting so as to make the golf club head 2. Therefore, it is not necessary to be concerned about the requirements for the prior art. Furthermore, the inner tubular part 212 extends downwardly into the hollow body portion 211 from the outer open end 213, and the non-metal tubular member 22 is made of a non-metal material, such as a carbon fiber reinforced material. Therefore, the center of gravity of the golf club head 2 can be lowered, and the overall weight of the golf club head 2 can be reduced.
Referring to
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.
