Abstract

A plurality of support ribs are formed on the inner surface of a light cover plate so that the thickness and weight of the light cover plate can be reduced, and the strength of the structure of the light cover plate can be increased. Therefore, it is possible to adjust the position of the center of gravity and further improve the stability of the hit ball.
An upper lid portion and a rear peripheral wall portion are formed on a light lid plate. A face plate portion 21, a crown portion 22 and a sole plate portion 23 are formed on the head body 2. The light cover plate 1 is coupled to the head main body 2 in a corresponding manner to form a golf club head jointly. Since the light cover plate 1 is made of a low specific gravity metal material and has a thickness of less than 0.6 mm, the center of gravity of the golf club head can be kept low. By providing the support rib 13 on the inner surface of the light lid plate 1, the strength of the structure of the light lid plate 1 can be enhanced.

  The conventional golf club head structure as described above generally has the following problems. For example, the center of gravity of the golf club head can be kept low by the recessed groove in the crown portion of the head body and the protruding rib in the sole portion. However, since the recessed portion is provided in the crown portion, The wall thickness is necessarily larger than the depth of the recessed groove. As a result, since the concave groove cannot actually reduce the weight of the crown portion in practice, there is a problem in that it is not possible to increase the stability of the hit ball while keeping the position of the center of gravity of the golf club head low. Thus, the structure of the conventional golf club head as described above must be further improved.

  Referring to FIGS. 1, 2, and 3 again, the light lid plate 1 of the embodiment of the present invention is formed with an upper lid portion 11, a rear peripheral wall portion 12 and a plurality of support ribs 13 so as to be integrally formed. A lid plate coupling portion (not shown) and a rear circumferential wall coupling portion (not shown) are formed on the upper lid portion 11 and the rear circumferential wall portion 13 respectively, and the lid plate coupling portion and the rear circumferential wall coupling portion are jointly formed. By forming the first coupling portion (not shown), the head main body 2 can be coupled in a corresponding manner. The lid plate coupling portion is provided with an upper coupling side 111, and the upper coupling side 111 is formed so as to be positioned at an edge of the upper lid portion 11. The rear peripheral wall coupling portion is provided with a bottom coupling side 121, and the bottom coupling side 121 is formed so as to be positioned at the edge of the bottom portion of the rear peripheral wall portion 12. The support ribs 13 are selectively installed so as to be arranged in parallel with the inner surface of the upper lid portion 11, thereby enhancing the strength of the structure of the light lid plate 1 and deforming when the light lid plate 1 receives an impact. It can be prevented from occurring. Further, the support rib 13 can be formed on the inner surface of the upper lid portion 11 so as to be integrally formed using a forming method such as punching or pickling.

  Referring to FIGS. 1, 2 and 3 again, the head body 2 of the embodiment of the present invention is formed with a face plate portion 21, a crown portion 22 and a sole plate portion 23 so as to be integrally formed. The face plate portion 21 is formed so as to be positioned between the crown portion 22 and the sole plate portion 23, and is formed so as to be positioned in front of the golf club head. A crown plate coupling portion (not shown) and a sole plate coupling portion (not shown) are formed on the crown portion 22 and the sole plate portion 23, respectively. By forming the coupling portion (not shown), the first coupling portion of the light lid plate 1 can be coupled in a corresponding manner. The crown plate coupling portion is provided with an upper coupling side 221 and a side coupling portion 222, and the upper coupling side 221 is formed so as to be positioned at a side edge of the crown portion 22, and the side coupling portion 222 is formed on the side of the head body 2.

  As described above, according to the structure of the conventional golf club head, the center of gravity of the golf club head is adjusted by providing a plurality of recessed grooves and a plurality of protruding ribs in the crown portion and the sole portion of the head body. However, since the thickness of the crown portion is inevitably larger than the depth of the recessed groove due to the installation of the recessed groove, the recessed groove can actually keep the position of the center of gravity of the golf club head low. However, according to the golf club head structure of the present invention shown in FIG. 1, the support ribs 13 are formed on the inner surface of the light cover plate 1 having a relatively thin thickness, and the light weight is further reduced. Since the cover plate 1 is selectively made of a metal material having a low specific gravity, the thickness and weight of the light cover plate 1 can be effectively reduced, and the strength of the structure of the light cover plate 1 can be maintained. Golf reliably adjust the position of the center of gravity of the club head, increasing the strength of the structure, it is possible to more effectively enhance the stability of the hit ball.
