Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club putter for hitting a golf ball toward a cup provided on a green.

[0002]

2. Description of the Related Art In a conventional golf club putter,
Usually, a hosel to which a shaft is attached is molded integrally with the head body by casting or the like. For example,
In an L-type or T-type putter, a cylindrical hosel that is inclined at a predetermined lie angle from the heel side of the head main body extends upward, and a shaft is mounted on the hosel. In a mallet-type putter that is frequently used recently, the hosel extending upward from one end of the head is bent forward in the middle so that the tip of the shaft is disposed in front of the face surface. Often, the shaft is inclined to a predetermined lie angle.

[0003]

However, in the conventional putter, the hosel is formed as a so-called gooseneck such that the tip of the shaft is disposed in front of the face surface, as in the mallet type putter described above, and the hosel is provided in the middle of its length. When the head is bent, the bending position and the degree of bending are fixed in advance at the time of molding the head, and it is extremely difficult to freely change these after molding according to the preference of each player. For example, in a mallet-type putter, it is sometimes used as a putter with a high degree of gooseneck according to the state of the golf course to be played, and at other times, it is used by changing to a so-called straight-type putter that rises straight up from the heel part It is impossible with conventional putters to achieve convenience such as doing. In addition, the lie angle of the conventional putter club is fixed at an angle set at the time of molding the head, and it is usually impossible to change the lie angle later according to the body shape and preference of each player.

[0004] The golf club putter according to the present invention solves the above-mentioned inconvenience. The purpose of the putter is to replace a hosel of various desired shapes with a molded putter head body. A golf club putter that can be mounted on a golf club is provided.

[0005]

In order to achieve the above object, a golf club putter according to the present invention has a hosel replaceable in a golf putter having a putter head comprising a head body and a hosel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a golf club putter according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are a front view and a plan view of a golf club putter according to the present invention. As shown in the front view of FIG. 1 and the plan view of FIG. 2, in the putter of this embodiment, a pin type made of soft iron casting (weight is distributed to the toe and the heel) is attached to the heel portion 2 of the putter head body 1. A hosel 3 made of an aluminum alloy, which is accurately formed by machining by NC processing, is attached. The lower end of the hosel 3 is provided with a rod-shaped fitting portion 4 and a flange 5 formed on the top of the fitting portion 4. The hosel 3 is attached to the head main body 1 by fitting the rod-shaped fitting portion 4 coated with a predetermined adhesive into the cylindrical hole 6 provided inside the heel portion 2 of the head main body 1. Is the head body 1
It is performed by being pushed and bonded until it comes into contact with the upper surface of the.

The diameter of the cylindrical fitting portion 4 is 8 to 10 mm depending on the size and weight of the head body 1 which is usually used.
However, it is preferably selected in the range of 8.5 to 9.5 mm. In this embodiment, the diameter is set to 9.0 mm, and the diameter of the flange 5 provided on the top of the fitting portion 4 is set to 1 mm.
0 mm.

In this embodiment, the rod-shaped fitting portion 4
Is a solid cylinder, but this can be made cylindrical with a hollow inside. Further, as the material of the hosel 3, various metal materials such as a metal magnesium alloy, a titanium alloy, stainless steel, and iron can be selected in addition to the aluminum alloy. The head body 1 can be made of various materials that can be bonded to a hosel.

The section of the hosel 3 which appears vertically upward from the flange 5 to the outside of the head body 1 has a rectangular cross section and a side length of 6.36 mm.
At the position of a predetermined height vertically extending above the head main body, the hosel outer portion has an upper end portion bent substantially at a right angle toward the front of the face surface 7 of the head main body 1, and a tip of the bent portion. Is provided with a cylindrical shaft mounting portion 8. This cylindrical shaft mounting portion 8
As shown in FIG. 1, the shaft 9 is inclined at a predetermined angle θ with respect to the ground when the putter is normally addressed so that the shaft 9 attached thereto has a desired lie angle.

In this embodiment, the angle θ of the shaft mounting portion 8 shown in FIG. 1 and therefore the lie angle of the shaft 9 are set to 70 degrees. Normally, it is considered preferable to set the lie angle of the shaft 9 in the range of 68 degrees to 72 degrees from the past results.

In this embodiment, the shaft 9 is
According to the inclination angle of the shaft mounting portion 8 shown in FIG. 1, the shaft is inclined to a predetermined lie angle, and when the putter head of FIG. Is substantially parallel to the direction of the hosel 3. Further, in order to set the direction of the shaft 3 in this manner, when the hosel 3 manufactured separately is attached to the head main body 1, as shown in FIG. Narrow groove 1 provided on top of shaft 9
This is performed by fitting the guide plate 11 in the inner space 0, looking down at the putter head from above, and fixing the hosel 3 at a position where the bottom side of the guide plate looks parallel to the top edge 7A of the face surface 7 (FIG. 3 and FIG. 4).

When replacing the hosel 3, the existing hosel 3 mounted as described above may be pulled out from the hole 6 of the head body 1, and a new hosel 3 may be mounted in the same procedure as described above. .

In the above-described embodiment, the flange 5 is provided on the top of the mounting portion of the hosel 3, but it is not always necessary to provide the flange 5 in practicing the present invention. In the embodiment, a so-called pin type putter club is used. However, the present invention is applicable to other types of putters such as a mallet type for the purpose of the present invention.

[0015]

As described above, according to the present invention, since the hosel can be replaced, the shape of the hosel can be changed to various shapes according to the player's preference while keeping the head body the same. Can be. Also, by freely changing only the material of the hosel, the combination of the material of the head body and the material of the hosel can be variously changed.

Further, when replacing the hosel,
The guide plate is attached to the hosel and the direction of one side of the guide plate and the length direction of the face surface of the head body are matched to determine the direction of the hosel with respect to the head body, so that the shape desired by the player can be obtained. The posture of the bent replacement hosel can be accurately set with respect to the direction of the head body, particularly the face surface.

Further, in the conventional putter, the head and the hosel are integrally formed by casting or the like, so that it is difficult to process the hosel into a delicate shape. N separately from the head body
