Abstract

A golf club head has a metal base, face and tubular neck and a carbon-fiber cover. The face extends up vertically from one edge of the base. The tubular neck is integrally connected to the base and the face. The cover is made of a carbon-fiber material and is securely attached to the base and the face. Because the carbon-fiber material is lighter than metal, the area of the face is enlarged. In addition, the shock absorbing effect of the golf head club is also improved.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention [0001]
  • The present invention relates to a golf club head and the method for forming the same, and more particularly to a golf club head with a large hitting face and good flexibility. [0002]
  • 2. Description of Related Art [0003]
  • In general, one of two ways are usually used to manufacture a golf club head. One is to form the head with a cast mold process, and the other is to weld several parts together. However, because the conventional golf club head is always made of metal and the weight of the golf club head is standardized, the area of the face of the golf club head is limited. A new golfer easily misses the golf ball with a golf club having a conventional head. In addition, the shock absorbing effect of the conventional golf club head formed by combining several parts is easily reduced because of the welding process. [0004]
  • To overcome the shortcomings, the present invention tends to provide an improved golf club head to mitigate or obviate the aforementioned problems. [0005]
  • SUMMARY OF THE INVENTION
  • The main objective of the invention is to provide an improved golf club head having a face with a large area. The golf club head has a metal base, face and tubular neck and a carbon fiber cover. The face extends up vertically from one edge of the base. The tubular neck is integrally connected to the base and the face. The cover is securely attached to the base and the face. Because the carbon-fiber material is lighter than the metal, the area of the face is enlarged. In addition, a better shock absorbing effect is achieved due to the carbon-fiber cover. [0006]
  • Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.[0007]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is an exploded perspective view of a golf club head in accordance with the present invention; [0008]
  • FIG. 2 is a block diagram of a method for manufacturing the golf club head in FIG. 1; [0009]
  • FIG. 3 is a side plan view in partial section of the golf club head in FIG. 1 with an air bag; and [0010]
  • FIG. 4 is a side plan view in partial section of the golf club head in FIG. 1.[0011]
  • DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
  • With reference to FIG. 1, a golf club head in accordance with the present invention comprises a base ([0012] 10), a face (11), a neck (12) and a cover (20). The base (10) is made of metal. A countersunk threaded hole (15) is defined in the base (10). A countersunk recess (16) is defined in the base (10) around the threaded hole (15). A threaded plug (18) with an enlarged head (17) is screwed into the threaded hole (15). Consequently, the threaded plug (18) is securely attached to the base (10) due to the engagement with the threaded hole (15).
  • The face ([0013] 11) extends up vertically from one edge of the base (10). Grooves are defined on the outside of the face (11). The neck (12) is a tubular member and is integrally connected to the base (10) and the face (11). A lip (14) is formed around the edges of the base (10) to form a cavity (13) between the base (10), the lip (14) and the face (11).
  • The cover ([0014] 20) is securely attached to the lip (14) and the face (11) to cover the cavity (13). At least one weighted plug (22) with an annular recess (23) in the outer edge is inlaid in the cover (20). A bore (21) is formed in the cover (20) to securely hold each weighted plug (22).
  • With reference to FIG. 1 and [0015] 2, the process of manufacturing the golf club head comprises the following steps:
  • a. forming the base ([0016] 10) and the face (11):
  • The base ([0017] 10) with the lip (14) and the face (11) are cast molded. Then, the tubular neck (12) is formed with a forging process. The countersunk threaded hole (15) and the circular recess (16) are drilled in the base (10) and the threaded hole (15) tapped.
  • b. thermal treatment: [0018]
  • The body comprising the base ([0019] 10), the lip (14), the face (11) and the neck (12) is thermally treated.
  • c. grinding: [0020]
  • The body is then ground to a desired shape and size. [0021]
  • d. spraying aluminum oxide sand onto the body: [0022]
  • By spraying the aluminum oxide sand onto the inner surface of the cavity ([0023] 13) of the body and the edge around the cavity (13), the surface roughness of the body is increased.
  • e. attaching the cover ([0024] 20) to the body:
  • The cover ([0025] 20) formed with multiple carbon-fiber layers. Multiple bores (21) are defined in the cover (20). The cover (20) with bores (2 1) is attached to the body to cover the cavity (13).
  • f. inlaying the weighted plugs ([0026] 22) into the cover (20):
  • A weighted plug ([0027] 22) is put into each bore (21) in the cover (20).
  • g. inserting an air bag ([0028] 30) into the body:
  • With reference to FIGS. 2 and 3, an air bag ([0029] 30) is inserted into the cavity (14) through the threaded hole (15) in the base (10). The body with the air bag (30) is then put into a hot-pressing machine.
  • h. inflating the air bag ([0030] 30) and hot pressing:
  • The air bag ([0031] 30) is inflated and expands to abut the inner surface of the cover (20) and the body, such that the outer surface of the cover (20) will press against the entire inner face of the mold in the hot-pressing machine. During the hot-pressing mold process, the cover (20) will harden and form to a shape conforming to the shape of the hot-pressing mold. The cover (20) will be securely attached to the base (10) and the face (11). Because the edge of the base (10) and the face (11) was sprayed with the aluminum oxide sand, the attachment between the cover (20) and the body is enhanced. The weighted plugs (22) received in the bores (21) will be securely held into the cover (20) when the cover (20) hardens during the hot-pressing mold process. In addition, with reference to FIG. 4, a rib (212) will be automatically formed in each bore (21) during the hot-pressing mold process to engage the annular recess (23) in each weighted plug (22). The combination between each weighted plug (22) and the cover (20) is enhanced. In another embodiment, an annular rib is formed on an outer edge of each weighted plug (22), such that a recess engaging with the rib of each second block (22) will be defined in each bore (21) during the hot-pressing mold process.
  • i. attaching the threaded plug ([0032] 18) to the base (10):
  • The air bag ([0033] 30) is taken out of the body. The threaded plug (18) is screwed into the threaded hole (15) in the base (10) so that the head (17) is flush with the outer surface of the base (10). Consequently, the position of the center of gravity of the golf club head is adjustable based on the size and placement of the threaded plug (18) and weighted plugs (22).
  • j. fine grinding: [0034]
  • To increase the smooth of the surface of the golf club head, a fine grinding process is carried out. [0035]
  • k. coating: and [0036]
  • The outer surface of the golf club head is coated with lacquer to provide a protective coating on the head. [0037]
  • l. packing: [0038]
  • The golf club head is packed. [0039]
  • Accordingly, a golf club head with a carbon-fiber cover ([0040] 20) is made. Because the weight of the carbon-fiber material is lighter than the metal, the weight of the golf club head is reduced. Consequently, a face (11) with a larger area can be formed on the golf club head that is the same weight as the conventional golf club head made of metal. The face is enlarged. The likelihood of completely missing the golf ball can be greatly reduced. In addition, because the elasticity of the carbon-fiber material is better than that of the metal material, the shock absorbing effect of the golf club head is improved.
  • Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. [0041]
