Wood golf club head

Abstract

A wood golf club head has a sole plate, a crown, a strike face and a hosel that are all made of metal and are welded together. The sole plate is formed by forging to have different thicknesses at different parts and has a weight formed as a thicker part of the sole plate. Therefore, when the wood golf club head is manufactured, the shape, the size and the position of the weight is precisely set based on the design of the wood golf club head. Then the gravity center of the wood golf club head is accurately determined. Moreover, since the weight is directly formed on the sole plate without any gaps and the shape of the weight is simple and smooth, the wood golf club head performs a clear and pleasing striking sound while it strikes.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head, especially to a wood golf club head.[0003]2. Description of the Prior Arts[0004]Wood golf club heads have special shapes so that the wood golf club heads are difficult to be formed as one piece. Therefore, the wood golf club heads made of metal are usually manufactured as two-pieces, three pieces or four pieces. The pieces are welded to form a wood golf club head with predetermined appearance.[0005]With reference to FIG. 4, a conventional wood golf club head with four pieces comprises a sole plate 20, a crown 21, a strike face 22, a hosel 23 and a weight 24. One side edge of the crown 21 is attached securely to an upper side edge of the sole plate 20. Side edges of the strike face 22 are respectively attached securely to front side edges of the sole plate 20 and the crown 21. The hosel 23 is connected securely to end edges of the sole plate 20, the crown 21 and the stri...

AI Technical Summary

Benefits of technology

[0009]The main objective of the present invention is to provide a wood golf club head that improves the forming process of the weight to precisely determine the position of the gravity center of the wood golf club head. The wood golf club head has a sole plate, a crown, a strike face and a hosel that are all made of metal and are welded together. The sole plate is formed by forging to have different thicknesses at different parts and has a weight formed as a thicker part of the sole plate. Therefore, when the wood golf club head is manufactured, the shape, the size and the position of the weight is precisely set based on the design of the wood golf club head. Then the gravity center of the wood golf club head is accurately determined. Moreover, since the weight is directly formed on the sole plate without any gaps and the shape of the weight is simple and smooth, the wood golf club head performs a clear and pleasing striking sound while it strikes.

Problems solved by technology

Wood golf club heads have special shapes so that the wood golf club heads are difficult to be formed as one piece.

However, the welding in intervals provide worse bond than welding at full periphery.

Furthermore, since the adjacent welded parts 25 also have a gap formed between them, the conventional wood golf club head cannot perform a clear and pleasing striking sound while it strikes.

Thus, the conventional wood golf club head has poor striking sound.
