FIG. 3 shows the method of manufacturing a golf club head disclosed in Taiwan Patent Application No. 90101576. The drawbacks of the conventional club head are that the excessive hardness of the impact is a waste of material and the cost of manufacturing is increasing, and the sweet spot of impact face of the conventional club head cannot be enlarged. Accordingly, it is an object of the present invention to provide an improved structure of a golf club head which mitigates the above-drawbacks. - Accordingly, an object of the present invention is to provide a golf club head having a bottom section made from a metallic material and a bottom housing having a hollow impact face, and the top section and the impact face being made from a complex material.
- The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
- Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
- FIGS. 1,2 and3 are conventional club head disclosed in Taiwan application nos. 84205250, 89110593 and 90101576.
- FIG. 4 is a perspective view of a preferred embodiment in accordance with the present invention.
- FIG. 5 is a side view of FIG. 4.
- FIG. 6 is an exploded view of another preferred embodiment in accordance with the present invention.
- The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
- Referring to FIG. 4, the club head comprises a
bottom housing 7 and ahousing cap 8 made of complex material to form a club head. Thebottom housing 7 includes abottom section 71, ahollow impact face 72 and arod head 73. The center of theimpact face 72 is hollow, and the bottom section 71 (or the side) is provided with anair inlet 74. Thehousing cap 3 is made from polycarbonate fiber or glass fiber complex material. As shown in FIG. 5, complex material impregnated cloth covers the rear side of thehollow impact face 72 of thebottom housing 7 and fills the hollow space to form animpact face 81, and the upper space of thebottom housing 7 is formed into atop section 82 and is then inserted into the mold. Air is pumped via theair inlet 74 so that the cloth is firmly closed to the inner wall of the mold. At the same time, a heating process is applied so that the cloth within the mold is set to form thebottom section 71 of themetallic material 7, thehollow impact face 72, theneck 73 combined with theimpact face 81, and thetop section 82. - Next, as the
impact face 31 is a complex material with a lower strength, theimpact face 81 is processed to remove the resin thereon so that the surface becomes a rough surface. Arc spray process provides a layer of higher hardness metallic material media onto theimpact face 81, and the media is then electroplated with an abrasive-resistant layer. The surface of theimpact face 81 is also coated with a metallic-abrasive-resistant layer, and thebottom 71 or the side is provided with the air-inlet 74 mounted with aheavy block 75. Finally, the semi-furnished product is undergone a process to form into a club head. - As the material for the bottom section, the
hollow impact face 72 and therod neck 73 is a metallic material, the coated layer (abrasion-resistant) is thin and the weight of the head will not be increased. As a result, the weight of the head will be reduced and the area of the club head can be enlarged so as to provide a wider impact face. When the impact face is enlarged, the sweet spot of impact is enlarged and it can provide a more effective impact. As theimpact face 81 is a material coated electroplated with a high abrasive-resistant layer, therefore theimpact face 81 of the club head has a better elasticity such that when the impact face 81 impacts with a ball, the ball will temporarily stay at the impact face which has a better control of the golf ball. Besides, the coefficient of elasticity of theimpact face 81 is higher, the ball can fly further when it impacts with the ball. Theair inlet 74 is provided with aheavy block 75, therefore the weight center of the head will be reduced and the swinging of club will be smooth. - Referring to FIG. 6, the
bottom housing 7 is a metallic material and comprises abottom section 71, ahollow impact face 72 and therod head 73, and ahousing cap 8. Thetop portion 82 is cast into animpact face 76. Thecast impact face 76 is welded onto the hollow section of theimpact face 72 and theheavy block 75 is mounted at the air-inlet 74 of the bottom section 71 (or the side), after that a furnishing process is performed until a final club head is obtained. - In accordance with the present invention, as the
impact face 76 is cast, theentire impact face 76 and the thickness of individual parts can be adjusted according to requirement and the turning center of theimpact face 76 can be adjusted, the turning center and the weight center of theimpact face 76 are located on the same point so that the sweet spot of the impact face is enlarged. In addition, the club head will not turn in the course of hitting a ball. Therefore, when hitting a ball at a horizontal face, the direction of the ball can be easily controlled. Thebottom housing 7 and theimpact face 76 are formed separately and therefore they can be made from different metallic material. In accordance with the present invention, thebottom housing 7 can be formed from metallic material of cheaper cost and theimpact face 76 is cast from a metallic material of higher cost. In view of the above, the cost of the club head can be reduced. - It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
- While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
