Title: Customizable golf club head

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to golf club head technology, and more particularly, to a customizable golf club head. 
     2. Description of the Related Art 
     The conventional golf club head is mainly made by casting technology in one piece and uses a mosaic method to fix a weight with the golf club head, so that the golf club head can play the best ball hitting effect. 
     In order to meet the weight requirements of different users, manufacturers must develop corresponding molds for each type of structural combination for manufacturing, but this will lead to the problem that the development costs are too expensive to meet the needs of customization. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a golf club head, which allows the most suitable structural combination to be tailored for different users, so as to achieve satisfying the needs of customization. 
     To achieve this and other objects of the present invention, a golf club head comprises a club head body, a first cover plate, and a second cover plate. The club head body comprises an arc-shaped top frame and an arc-shaped side frame. Both ends of the curved top frame are integrally connected to both ends of the curved side frame. The curved top frame and the curved side frame are not located on the same imaginary planes, so that a first slot and a second slot are formed therebetween and disposed in communication with each other. The first cover plate comprises a crown, and a ball-hitting face integrally downwardly extended from one end of the crown. The first cover plate covers the first slot of the club head body. The crown and ball-hitting face of the first cover plate are respectively affixed to the arc-shaped top frame and arc-shaped side frame of the club head body. The second cover plate covers the second slot of the club head body and is affixed to the arc-shaped top frame and arc-shaped side frame of the club head body. 
     As can be seen from the above, the first cover plate and the second cover plate can be manufactured using the same or different materials, so that the position of the center of gravity of the overall structure differs depending on the material difference of the first cover plate and the second cover plate. In this way, the most suitable structural combination can be tailored for different users, so that each user can show the best ball hitting effect. 
     Preferably, the arc-shaped top frame further comprises a first positioning groove located on an inner circumference thereof. The arc-shaped side frame further comprises a second positioning groove located on the outer side thereof and connected to the first positioning groove. The crown of the first cover plate comprises a first positioning convex portion located on an outer circumference thereof. The ball-hitting face of the first cover plate comprises a second positioning convex portion located on the inner side thereof and connected to the first positioning convex portion. The first positioning convex portion and the second positioning convex portion are respectively engaged in the first positioning groove and the second positioning groove. 
     More preferably, the second cover plate can be made of a material having a specific gravity greater than 7.8, such as stainless steel or tungsten nickel alloy. 
     The detailed construction, features, assembly or use of the golf club head provided by the present invention will be described in the detailed description of the subsequent preferred embodiment. However, those of ordinary skill in the art should understand that the detailed description and specific embodiments of the present invention are merely used to illustrate the present invention and are not intended to limit the scope of the patent application.

     DETAILED DESCRIPTION OF THE INVENTION 
     The applicant first explains here, in the embodiment and drawings, which will be described below, the same reference numerals denote the same or similar elements or structural features thereof. 
     Referring to  FIGS. 1-4 , a golf club head  10  in accordance with the present invention is shown. The golf club head  10  comprises a club head body  20 , a first cover  30 , and a second cover plate  40 . 
     The club head body  20  is made of titanium, stainless steel, aluminum or carbon fiber in one piece. The club head body  20  comprises an arc-shaped top frame  21  and an arc-shaped side frame  23 , and both ends of the curved top frame  21  are integrally connected to both ends of the curved side frame  23 . Moreover, the curved top frame  21  and the curved side frame  23  are not located on the same imaginary plane, so that a first slot  25  (as shown in  FIG. 2 ) and a second slot  26  (as shown in  FIG. 4 ) are formed therebetween and disposed in communication with each other. More specifically, the arc-shaped side frame  23  is inclined downward by a predetermined angle with respect to the arc-shaped top frame  21  such that the top side of the arc-shaped top frame  21  and the outer side of the arc-shaped side frame  23  surround the first slot  25 , the bottom side of the arc-shaped top frame  21  and the inner side of the arc-shaped side frame  23  surround the second slot  26 . 
     The first cover  30  is made of titanium, stainless steel, aluminum or carbon fiber in one piece. The first cover  30  comprises a crown  31 , and a ball-hitting face  33  integrally downwardly extended from one end of the crown  31 . When assembled in the club head body  20 , as shown in  FIGS. 1 and 2 , the outer circumference of the crown  31  of the first cover plate  30  and the inner side of the ball-hitting face  33  of the first cover plate  30  are respectively affixed to the inner circumference of the arc-shaped top frame  21  of the club head body  20  and the outer side of the arc-shaped side frame  23  of the club head body  20  by welding, so that the first cover plate  30  covers the first slot  25  of the club head body  20 . In order to help the first cover plate  30  to complete the assembly alignment quickly, as shown in  FIGS. 3-5 , the inner circumference of the arc-shaped top frame  21  of the club head body  20  and the outer side of the arc-shaped side frame  23  of the club head body  20  may further be respectively provided with a first positioning groove  22  and a second positioning groove  24  that connects the first positioning groove  22 , and the outer circumference of the crown  31  of the first cover plate  30  and the inner side of the ball-hitting face  33  of the first cover plate  30  may further be respectively provided with a first positioning convex portion  32  and a second positioning convex portion  34  that connects the first positioning convex portion  32 . By means of engaging the first positioning convex portion  32  and second positioning convex portion  34  of the first cover plate  30  into the first positioning groove  22  and second positioning groove  24  of the club head body  20  respectively, the invention reduces errors that may occur during assembly, avoiding ball hitting interference due to assembly errors. 
     The second cover plate  40  is made of a material having a specific gravity greater than 7.8 (for example, stainless steel or tungsten-nickel alloy) in an integrally formed manner. When assembled in the club head body  20 , as shown in  FIGS. 3 and 4 , the outer circumference of the second cover plate  40  is fixed to the bottom side of the arc-shaped top frame  21  of the club head body  20  and the inner side of the arc-shaped side frame  23  of club head body  20  by welding, so that the second cover plate  40  covers the second slot  26  of the club head body  20 . 
     As can be seen from the above, the first cover plate  30  and the second cover plate  40  can be manufactured using the same or different materials, so that the position of the center of gravity of the overall structure differs depending on the material difference of the first cover plate  30  and the second cover plate  40 . It is not necessary to develop a large number of different molds, so that the most suitable structural combination can be tailored for different users, so as to achieve cost saving and satisfying the needs of customization.
