Benefits of technology

[0006] An object of the present invention is to provide a vibration-absorbing structure for a golf club shaft that provides improved vibration-absorbing effect.
[0007] Another object of the present invention is to provide a vibration-absorbing structure for a golf club shaft that provides increased gripping comfort. SUMMARY OF THE INVENTION
[0012] In another embodiment, the light vibration-absorbing member includes a plurality of protruded sections in contact with the tubular wall and a plurality of recessed buffering sections not in contact with the tubular wall. The protruded sections and the recessed buffering sections are alternatively disposed, providing a multi-stage vibration-absorbing effect.
[0015] In yet another embodiment, two of the columns adjacent to each other are spaced by a spacer, providing a multi-stage vibration-absorbing effect.

Problems solved by technology

However, the vibration could not be completely absorbed, and the unabsorbed vibration is transmitted to the golfer's hands.
The hands of a golfer that plays for a long time might feel uncomfortable or numb.
The striking accuracy is thus adversely affected.
The hands of the golfer might even be injured.

Embodiment Construction

[0038] Referring to FIGS. 2 and 3, a golf club in accordance with the present invention comprises a shaft 10, a head 20, a grip 30, and a light vibration-absorbing member 40. The shaft 10 is an elongated tubular member with the head 20 coupled to an end thereof and with the grip 30 coupled to the other end thereof. The shaft 10 includes a tubular wall 11 delimiting an interior space 12.

[0039] The shaft 10 is made of a material having a high coefficient of restitution so as to be highly flexible. In an example, the shaft 10 is formed by a plurality of windings of carbon fiber prepreg. Alternatively, the shaft 10 is integrally formed by metal or alloy. The light vibration-absorbing member 40 is received in the interior space 12 of the shaft 10. The head 20 is of an iron club type, wooden club type, or putter type. The head 20 is used to strike a golf ball. The grip 30 is made of an elastomeric material such as rubber, allowing a golfer to grip for swinging or putting purposes.

Abstract

A golf club shaft includes a shaft having a tubular wall delimiting an interior space. The shaft includes a first end coupled with a head and a second end coupled with a grip. A light vibration-absorbing member is mounted in the interior space of the shaft. At least a portion of the light vibration-absorbing member is in contact with the tubular wall for absorbing vibration that results from striking a golf ball and that is transmitted from the head to the shaft.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a vibration-absorbing structure. In particular, the present invention relates to a vibration-absorbing structure for a golf club shaft. [0003] 2. Description of Related Art [0004]FIG. 1 of the drawings illustrates a conventional golf club comprising a shaft 10, a head 20, and a grip 30. The shaft 10 is substantially an elongated tubular member with the head 20 coupled to an end thereof and with the grip 30 coupled to the other end thereof. The shaft 10 is made of a material having a high coefficient of restitution. For example, the shaft 10 can be formed by a plurality of windings made of carbon fiber prepreg, graphite fiber prepreg, or fiberglass. Thus, the shaft 10 is highly flexible. The head 20 is used to strike a golf ball and the grip 30 allows firm grip by the golfer. Such a golf club head is disclosed in, e.g., U.S. Pat. Nos. 3,313,541; 4,023,801; 4,135,035; and 5,437,450.
