Benefits of technology

The patent describes a golf club head that has increased volume while maintaining strength and aligning the center of gravity with the hitting spot. This is achieved by using a titanium alloy and creating recesses on the inside surface of the head. The recesses reduce the weight of the top lid, which lowers the center of gravity and improves the efficiency of hitting. Additionally, the strength of the head is improved, optimizing performance and increasing lifespan. The method of manufacturing involves cutting a blank, preheating it, and forging it with a mould to create the recesses and ribs. The precision of the recesses depends on the precision of the mould, but the overall precision of the head is improved by keeping the precision of the mould.

Problems solved by technology

However, in order to increase the volume of the head without increasing its weight, it has to reduce the thickness of walls of the head, which will hereby cause the strength and rigidity of the head reduced.
In addition, reducing the thickness of walls may change the center of gravity of the head.

Embodiment Construction

[0018]Hereinafter, implementations will be described in detail with reference to the accompanying drawings.

[0019]Referring to FIGS. 1 and 2, a golf club head 10 comprises a head base 3, a hitting face 4 at a front edge of the head base 3 and a top lid 1 on the top of the head base 3. The head base 3 has a neck 5 for connecting with a club (not shown). The top lid 1 has an inside surface 2 and an outside surface 6 opposite to the inside surface 2. The head base 3, the hitting face 4 and the top lid 1 are connected with each other to form a close entirety.

[0020]Now referring to FIGS. 3 and 4, a plurality of recesses 21 are formed in the inside surface 2 of the top lid 1. The plurality of recesses 21 are arranged bilateral-symmetrically, and each of the plurality of recesses 21 has the same depth. In this condition, the weight of the top lid 1 may be symmetrically arranged such that the club may swing more smoothly.

[0021]FIG. 4 shows an example of the arrangement for the recesses 21. A...

Abstract

A titanium alloy golf club head and a method for manufacturing the same are provided. The golf club head comprises a head base, a hitting face at a front edge of the head base and a top lid on the top of the head base. The head base, the hitting face and the top lid are connected to each other to form an entirety. The top lid has an inside surface comprising a plurality of recesses. With the recesses, the weight of the head is reduced while the volume of the head is increased. Meanwhile, the thickness of walls of the head base and of the hitting face does not need to be reduced. Since the weight of the top lid is reduced, the center of gravity of the head is lowered. A rib is formed between two adjacent recesses in the inside surface of the top lid so that an impact force on the head can be efficiently dispersed and the strength of the head is improved.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present application is related to a golf club head.BACKGROUND OF THE INVENTION[0002]A titanium alloy golf club head is mainly used as golf club head #1, the weight of which is generally 194±3 grams. It has been evidenced that this is an optimal range of weight for hitting golf according to repeated experiments. During hitting, the larger the head's volume is, the larger the air resistance to the head will be and the more smoothly the club will sweep. Thus, the more the hitting performance will be improved.[0003]However, in order to increase the volume of the head without increasing its weight, it has to reduce the thickness of walls of the head, which will hereby cause the strength and rigidity of the head reduced. Thus, the life time and performance of the head will be reduced. In addition, reducing the thickness of walls may change the center of gravity of the head.SUMMARY OF THE INVENTION[0004]A golf club head is disclosed, which is able ...
