Benefits of technology

[0006] According to the hollow golf club head, the viscoelastic body is mounted in the part of the portion where the viscoelastic body is to be mounted, the part corresponding to the antinode of the primary vibration mode. The part corresponding to the antinode of the primary vibration mode is where the magnitude of the vibration becomes the largest. Therefore, when the viscoelastic body is mounted in this portion, the vibration of the golf club head can be suppressed more effectively.

Problems solved by technology

Therefore, the viscoelastic body may not exhibit its vibration suppressing function effectively.

Embodiment Construction

[0015] Preferred embodiments of the present invention will now be described in detail in accordance with the accompanying drawings.

[0016]FIG. 1A is a view showing the outer appearance of a golf club head A according to an embodiment of the present invention, and FIG. 1B is a sectional view of the golf club head A taken along the line X-X (extending through substantially the center in the toe-to-heel direction) of FIG. 1A. The golf club head A forms a hollow body, and its circumferential wall constitutes a face portion 10 which forms a golf ball hitting surface, a crown portion 20 which forms the upper surface of the golf club head A, a sole portion 30 which forms the bottom surface of the golf club head A, and a side portion 40 which forms the toe-side, heel-side, and back-side side surfaces of the golf club head A. The golf club head A also has a hosel portion 50 to which a shaft is to be attached.

[0017] The golf club head A can be made of, e.g., a titanium-based metal material. ...

Abstract

This invention provides a hollow golf club head having a face portion, a crown portion, a sole portion, and a side portion, and comprising a viscoelastic body to be mounted in at least one of the face portion, crown portion, sole portion, and side portion. The viscoelastic body is mounted in a part of a portion where the viscoelastic body is to be mounted, the part corresponding to an antinode of a primary vibration mode.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a golf club head and, more particularly, to a technique for controlling vibration of a golf club head by a viscoelastic body. BACKGROUND OF THE INVENTION [0002] A technique for controlling vibration of a golf club head has been developed to improve the hitting impression or adjust the hitting sound on impact. Japanese Patent Laid-Open No. 2004-313777 discloses a golf club head having a viscoelastic body. When the viscoelastic body is attached, the vibration on impact is absorbed by the viscoelastic body to improve the hitting impression and decrease the hitting sound that is offensive to the player's ear. Japanese Patent Laid-Open No. 2005-6763 discloses analyzing the vibration mode of a golf club head by a computer to correct the thickness and the like of the materials that form the golf club head. Japanese Patent Laid-Open No. 2003-102877 discloses providing a metal rib to a part corresponding to the antinode of the se...
