Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club capable of approach shots and putter shots.

[0002]

2. Description of the Related Art In a golf club that performs a putter shot (hereinafter referred to as a putter), the loft angle of the face is set to 0 ° or near 0 ° in order to roll the ball along the ground surface on the green. On the other hand, a golf club performing an approach shot (for example, pitching) drops the ball on the green so that the ball can be moved from the periphery of the green to the cup on the green, and the dropped ball does not roll on the green. , The structure that gives a backspin to the ball while launching it upward. Specifically, a golf club that performs an approach shot has a large loft angle to hit the ball, and a plurality of score lines (grooves) are formed to apply backspin to the ball.

[0003]

Since the putter is relatively easy to control the ball, the putter is a very effective club for approaching from the periphery of the green. However, since the green is usually set higher than the periphery of the green, it often happens that a putter having a structure in which the ball rolls along the ground surface cannot be used for approach shots. In this way, when the approach shot cannot be performed using the putter, a golf club with a large loft angle and multiple score lines, such as pitching, is used to launch the ball and backspin the ball to the approach shot. The need arises. However, it requires a high level of skill to launch the ball, apply backspin to the ball, and drop the ball to the intended place. If it fails, the score will be greatly disturbed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. An object of the present invention is to provide a golf club which rolls a ball along the ground surface so that an approach shot can always be taken from the periphery of the green. It is in the provision of a club.

[0005]

The golf club of the present invention employs the following technical means. [Means of Claim 1] A golf club according to claim 1 comprises a shaft having a length suitable for a putter shot swung by a user, and a club head provided at the tip of the shaft. The club head has a putter face having a small loft angle and an approach face having a loft angle larger than the loft angle of the putter face on a surface different from the putter face. further,
The club head is provided on the shaft through a face surface changing mechanism to which the putter face or the approach face is directed with respect to the swing direction of the shaft. The small loft angle includes the loft angle of 0 °.

[Means for Claim 2] In the golf club according to claim 1, the face surface changing mechanism has a fixing arm fixed to an end portion of the shaft, and a groove portion provided on an upper surface of the club head. A substantially V-shaped arm having a fitting arm that fits in a hole, a pin fixed in the hole formed in the vertical direction of the club head and fixed to the fitting arm, and a hole in the hole. The compression coil spring has a lower end regulated by the pin and an upper end configured to urge the club head upward.

Action of the Invention and Effect of the Invention

[Operation of Claim 1] When hitting a ball around the green or the like and making an approach shot that does not require a great flight distance, the approach face is directed in the swing direction of the shaft and the ball is shot as if it were a putter. Then, the ball is launched and the ball flies by a flight distance according to the swing amount. On the other hand, when performing a putter shot in which the ball rolls along the ground surface such as on the green, the putter face is directed in the swing direction of the shaft, and the ball is shot as if a normal putter shot is performed. Then,
The ball rolls along the ground surface, and the ball rolls for a distance according to the swing amount.

[Advantage of Claim 1] A normal putter shot can be performed by orienting the putter face in the swing direction of the shaft. In addition, the approach face can be performed by directing the approach face in the swing direction of the shaft and hitting the ball up as if it were a putter shot. In other words, because it is possible to perform an approach shot that hits the ball with the feeling of a putter shot, compared to the conventional technology that hits the ball and backspins the ball to the target place as in the past. Then, the ball can be easily shot to a desired position.

When the putter face or the approach face is changed in the swing direction of the shaft, the club head is moved downward with respect to the arm so as to further compress the compression coil spring arranged in the hole. To move the fitting arm of the arm out of the groove on the upper surface of the club head. With the fitting arm protruding from the groove, the club head is rotated around the pin, the target face (putter face or approach face) is oriented in the swing direction of the shaft, and the fitting arm is fitted into the groove. Then, the fitting arm is fixed in the groove by the extension force of the compression coil spring.

[Effect of Claim 2] As described above, the putter face or the approach face can be oriented in the swing direction of the shaft by a simple operation of pulling the club head downward and rotating the club head. . Further, the fitting arm of the arm fits into the groove portion of the club head, and the pin, the compression coil spring, and the like are arranged in the hole of the club head and are not visible from the outside. That is, the face surface changing mechanism is invisible from the outside. In this way, from the appearance of the golf club, it does not look like a golf club that can switch between the putter face and the approach face, and therefore does not give a feeling of strangeness to the person who views the golf club.
