Abstract

PURPOSE:To provide a metal wood type golf club excellent in a shot property, difficult to break down a club shaft, providing a satisfactory ball driving feeling and improving substantially the strength of a club head. CONSTITUTION:While a hollow metal shell 11 of a club head 10 is formed integrally with a tubular part 14 projecting upward obliquely from one end side of the upper surface, a fitting hole 15 is formed in a position on the axis coaxial with the tubular part in a sole part 11b on the bottom surface and the tip of the club shaft 13 in the club head 10 is fitted in the fitting hole 15 from the tubular part 14 through the hollow shell 11 to be connectively fixed. The golf club has the peripheral surface of the club shaft 13a directly enclosed by a synthetic resin foamed body 12 in the hollow shell 11.

2. Description of the Related Art Conventionally, as shown in FIG. 4, for example, a club head in a metal wood has a club shaft (2) for inserting a club shaft (2) on one end side of the upper surface of a metal hollow shell (1), that is, on the heel side. A tubular portion (3) called a hosel is provided obliquely upward, and an inner extension portion (3a) of the tubular portion (3) hits the face portion (1a) to the heel side peripheral surface (1b). It has a structure that reaches the sole part (1c) of the bottom surface in an integrated form, and is provided in the extension part (3a) in the hollow shell (1) for the purpose of imparting a sound deadening effect at the time of hitting the ball. Polyurethane resin (not shown) is injected and foamed through the hole (4) to complete the filling.

From the viewpoint of increasing the centrifugal force of the club at the time of hitting the ball and increasing the hitting force against the ball,
It is desirable that the center of gravity be as close to the tip end side as possible, that is, the toe side of the head. However, in the conventional metal wood club head, the center of gravity is generally due to the presence of the inner extension portion (3a) of the cylindrical portion (3). Since it is located on the side, that is, on the heel side, there is a drawback that it is inferior in hitting property. In recent years, a carbon shaft made of carbon fiber has been widely used as the club shaft (2). However, in the conventional metal wood, the club shaft (2) is connected to the head by a ball impact, that is, the cylindrical portion (3). There is a problem that the ball easily breaks at the tip position and the shot feeling is poor.

In view of the above-mentioned circumstances, the present invention provides a metal wood type golf club which is excellent in hitting property, is less likely to cause breakage of the club shaft, and has a good shot feeling. It is an object of the present invention to provide a club head that can greatly improve its strength.

That is, in the golf club according to the present invention, as means for achieving the above-mentioned object, a cylindrical portion projecting obliquely upward from one end side of the upper surface is integrally formed on the metal hollow shell of the club head, and the bottom surface is formed. A fitting hole is formed in the sole portion of the sole portion at a position coaxial with the tubular portion, and a club shaft is inserted into the club head from the tubular portion through the hollow shell to fit the tip of the shaft into the fitting hole for connection. The club shaft is fixed and the peripheral surface of the club shaft in the hollow shell is directly encapsulated by the synthetic resin foam filled in the hollow shell.

In the golf club of the present invention, the peripheral surface of the club shaft inserted into the hollow shell of the club head is directly covered with the synthetic resin foam in the hollow shell, and includes the face portion of the hollow shell. Since the peripheral wall is separated from the club shaft, the impact applied to the club shaft at the time of hitting is softened by the cushioning action of the synthetic resin foam, and the impact stress is dispersed without being concentrated on the neck portion of the club shaft. The club shaft is less likely to be broken, and a good shot feeling can be obtained by the impact buffering function.

However, in the club head according to the present invention, the tubular portion for inserting the shaft does not extend into the hollow shell as in the conventional case, and the weight on the heel side is reduced accordingly, and the above-mentioned conventional extension is achieved. Since the weight equivalent to the part can be dispersed in the other part of the hollow shell, the center of gravity can be largely shifted to the toe side as compared with the conventional one, and good hitting performance can be obtained. Further, if the weight equivalent to the above-mentioned extended portion is utilized for forming ribs such as the inner surface of the face portion of the hollow shell, the strength of the club head is greatly improved.
