Abstract

PURPOSE: To provide a putter capable of the easy control of a face surface, driving a ball with a feeling of enveloping the ball by hands to easily place the ball on an aimed line and making it difficult to pull the face surface with back swing. CONSTITUTION: A shaft mounting part 3 is formed integrally with a head 1 offset from a face surface 2 in the direction of flight ball line in the nearly same height position as the face surface 2. The shaft mounting part 3 is formed with a hosel hole 4 in which a shaft is fixedly inserted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putter for a golf club.

[0002]

2. Description of the Related Art In some conventional putters, the shaft is located closer to the direction of the flight line than the face surface of the head, that is, in front of the face surface. In this case, the hosel is bent and becomes a gooseneck. Alternatively, the shaft directly attached to the head may be bent. The shaft is located in front of the face surface, making it easy to catch the ball.

[0003]

Even when the hosel or the shaft is bent and the shaft is positioned in front of the face surface, the entire head surface is flat and the entire front surface is flat when the ball is impacted. It was difficult to make the face face square with respect to the target and hit the core, which required skill.

Therefore, the present invention provides a putter in which the face surface can be easily controlled, the player can hit the ball as if he / she squeezed it with his / her hand, and the ball can be easily placed on the intended line, and the backswing is difficult to pull outside. With the goal.

[0005]

In order to achieve the above object, the present invention forms a shaft mounting portion integrally with the head and closer to the flying surface than the face surface and at substantially the same height as the face surface. The hosel hole for inserting and fixing the shaft is formed in the shaft mounting portion.

[0006]

In the present invention, the shaft mounting portion is formed integrally with the head, and this portion projects more than the face surface. Therefore, the ball can be hit with the feeling of wrapping it by hand. It is easy to put the hit ball on the target line. Further, since the shaft attachment portion is present in front of the face surface, the head can be easily pulled inside by the backswing, and there is no possibility that the face surface is opened or worn when hitting by hitting the outside. Furthermore, since the shaft mounting portion is not at a position higher than that of the face surface as in the past, but at the same height position as the face surface, it is easy to control the face surface, and the orientation of the face surface is set to the target. It is easy to make a square.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

In the head 1 shown in FIG. 1, the shaft mounting portion 3 is integrally formed with the head 1 in the direction of the flight line of the face 2, that is, in the frontward direction, and at the same height as the face 2.
Has been formed. A hosel hole 4 for inserting and fixing the shaft 5 is formed in the shaft mounting portion 3. The weight of the head of the putter according to the invention can be adjusted to the desired value within 280-360 g. For example, when it is formed as a lump of aluminum, the weight can be about 320 to 330 g. Also, a weight member made of lead, tungsten, or the like can be placed near the toe side or the heel side of the head 1 to balance the face. When the putter was molded from solid aluminum, a very soft feel was obtained. In this embodiment, the weight distribution to the heel portion is increased, and it is difficult to pull the heel to the outside during the backswing. Even if the core is removed, mistakes are less likely to occur because the ball is hit on the heel side.

As the shaft 5, not only the shape shown in FIG. 2 (bent on the heel side near the head 1) but also various shapes can be used. For example, a straight shaft can be used. Further, when fixing the shaft 5 to the head 1, the shaft 5 can be fixed substantially perpendicular to the horizontal axis 10 of the head 1 as shown in FIG. It may be fixed at a desired angle other than 90 °. The angle θ formed by the axis of the shaft 5 and the axis 10 is preferably 60 to 80 °.
And

FIGS. 3 to 5 are plan views showing the head shape of a putter according to an embodiment of the present invention. In the example shown in FIG. 3, the rear part of the center part of the face has the most swollen shape. With such a putter, a very good feel can be obtained. Further, in the example shown in FIG. 4, the rear part on the toe side is the most inflated. With such a head, the sweet area becomes wider. Furthermore, in the example shown in FIG. 5, the rear part on the heel side has the most expanded shape. With such a shape, it becomes more difficult to pull the ball to the outside during the backswing, and the control of the ball is further improved. The putter of the type shown in FIGS. 1 to 5 is called a so-called mallet type and has a deep center of gravity and a wide sweet area.

The embodiment shown in FIGS. 6 and 7 shows a type in which a large amount of weight is distributed to the toe side and the heel side. Since the weight is distributed to the toe and heel, the sweet area is wide and the inertia is large. The momentum is also large.
Further, in the head of the embodiment shown in FIGS. 5 and 6,
When the main body of the head 1 is made of a relatively heavy material such as copper, copper alloy, iron, iron-based alloy, titanium, aluminum is formed in the recess formed at the rear of the head 1 (on the side opposite to the face surface 2). , FRP or the like having a relatively low specific gravity may be inserted and fixed. With this structure,
The moment of inertia can be increased, and at the same time, a good feel can be obtained.

As the material used for the head 1, in addition to aluminum, materials such as stainless steel, brass, and soft iron can be used. Further, the head 1 may have a hollow structure. Furthermore, different materials can be combined.

[0013]

As described above, according to the present invention, the shaft mounting portion is formed integrally with the head at a position closer to the flight line than the face surface and at a position substantially the same height as the face surface. Since the hosel hole for inserting and fixing the shaft is formed in the portion, it becomes easier to control the face surface as compared with the case where the mounting position of the shaft tip is higher than the face surface. Further, since the shaft mounting portion is located in front of the face surface, the player can hit the ball as if he or she squeezes it in with a hand, so that the ball can be easily placed on the line. Further, since the shaft attachment portion is located in front of the face surface, it becomes easier to pull the shaft inside when the backswing is performed, and the possibility of pulling the shaft outside is reduced.
