Abstract

A golf club of the present invention comprises at least one adjusting mechanism. In the golf club, at least two specifications can be adjusted independently of each other. Preferably, a head, a shaft, a grip, or a joined part therebetween has an adjusting mechanism (1). The head, the shaft, the grip, or the joined part has further other adjusting mechanism (2). Preferably, the adjusting mechanism (1) and the adjusting mechanism (2) can work independently of each other. The number of the adjusting mechanisms is not restricted. Since the plurality of specifications can be adjusted independently of each other, a degree of freedom of adjustability is improved. These adjusting mechanisms can improve accuracy of the adjustability. The specification capable of being adjusted is not restricted.

Claims

1. A golf club comprising at least one adjusting mechanism, wherein at least two specifications can be adjusted independently of each other.

2. The golf club according to claim 1, wherein a head, a shaft, a grip, or a joined part therebetween has an adjusting mechanism (1);

the head, the shaft, the grip, or the joined part has further other adjusting mechanism (2); and

the adjusting mechanism (1) and the adjusting mechanism (2) can work independently of each other.

3. The golf club according to claim 2, wherein the adjusting mechanism (1) or the adjusting mechanism (2) is located at a place other than a hosel part.

4. The golf club according to claim 2, wherein the adjusting mechanism (1) and the adjusting mechanism (2) are located at places other than a hosel part.

5. The golf club according to claim 1, wherein all the adjusting mechanisms are located at places other than a hosel part.

6. The golf club according to claim 1, wherein the two or more specifications selected from a loft angle, a lie angle, a face angle, a face area, a position of a center of gravity of a head, a swingweight, a club length, a position of a center of gravity of a club, a frequency of the club, a club weight, ahead shape, a head volume, a head weight, a flex of a shaft, a flex point of a shaft, a torque of the shaft, flexural rigidity distribution of the shaft, torsional rigidity distribution of the shaft, a shaft weight, weight distribution of the shaft, a position of a center of gravity of the shaft, a length of the shaft, a grip outer diameter, a grip weight, a position of a center of gravity of a grip, a grip length, a specification of a face groove, a face progression, a moment of inertia of the head, a moment of inertia of the club, a coefficient of restitution of the head to a ball, and a friction coefficient of the head to the ball can be adjusted independently of each other.

7. The golf club according to claim 1, wherein the plurality of specifications include one or more specific specifications selected from a loft angle, a lie angle, a club length, and a club weight;

and an adjustment range is equal to or greater than a width corresponding to two-number clubs in all the specific specifications.

8. The golf club according to claim 1, wherein the golf club includes a sleeve changing mechanism as the adjusting mechanism.

9. The golf club according to claim 1, wherein the golf club has a first adjusting mechanism, a second adjusting mechanism, and a third adjusting mechanism, and the three adjusting mechanisms can work independently of each other.
