Abstract

A golf club head includes a ferrule at one side for connecting a club, a striking face formed in a front side, and an angle indicating device fitted in an upper center portion of the club head easily seen by a player. The angle-indicting device has a pointing member and an angle indicating marks. Then a golf player can look at the point of the angle indicating marks where the top of the pointing member is pointing to, and adjust and confirm the angle between the striking surface of the club head and the ball according to the condition of the courses of the gold link. Thus a player can strike a ball with the best angle to achieve striking stability by means of the angle-indicating device.

Claims

1. A golf club head comprising a ferrule at one side for connecting a club, a striking surface formed in a front side, and an angle indicating device fixed in an upper center portion of said club head, said angle indicating device comprising:

A supporting case consisting of two lengthwise walls and two sidewalls and a bottom defining an interior hollow with an open upper side,

A rotary shaft positioned between said two lengthwise walls in a center portion;

A pointing member supported by said rotary shaft to rotate with the rotary shaft, having a low center of gravity to keep the top always positioned to the upper side;

A golf player looking at said pointing member in said angle indicating device for confirming the angle between the striking surface and a ball to be struck, said angle indicating device having efficiency for a golf player to enhance striking stability.

2. The golf club head as claimed in claim 1, wherein said pointing member has its top provided with an obvious mark.

3. The golf club head as claimed in claim 2, wherein said obvious mark is brilliantly colored.

4. The golf club head as claimed in claim 1, wherein said angle indicating device further includes angle indicating marks for said pointing member to point to.

5. The golf club head claimed in claim 4, wherein said angle indicating marks are made on an upper surface of either of said two lengthwise walls.
