Abstract

PURPOSE:To enable a face material to be replaced according to the physical condition of the user and the condition of a golf course and to enable adjustment of the loft angle by forming the face material using a member independent of a head main body, and enabling the face material to be replaced for the head main body. CONSTITUTION:A head main body 1, molded integrally with a neck portion 2 into which a shaft is inserted, has a cavity 3 formed therein and tapped holes 5 formed therethrough to mount a face material 4 thereon. The face material 4 is formed of a member independent of the head main body 1 and has tapped holes 6 formed through its portions corresponding to the tapped holes 5 of the head main body 1. The face material 4 is mounted on the head 1 by means of screws 7. The thickness of the face 4 in the vertical direction is varied to adjust the loft angle. Therefore a golfer can replace the face material if necessary and easily make fine adjustments according to his physical condition and taste. The degree of goose and the loft angle can be finely adjusted by varying the thicknesses of the face material in the horizontal and vertical directions.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to golf club heads.

[0002]

2. Description of the Related Art Among conventional golf club heads, there is known a so-called composite club in which a face member is formed of a member separate from the head body. For example, a head body made of stainless steel to which a face material made of carbon fiber reinforced resin is fixed is known. Alternatively, a face material using a titanium alloy is also known. In any of the conventional composite clubs, the face material once attached to the head body cannot be easily removed.

[0003]

In conventional golf club heads, the face material cannot be freely replaced by the user, and the loft angle and the like cannot be changed. In other words, it is better to have a face material made of carbon fiber reinforced resin with a lot of runs that does not spin easily in clubs that want a long flight distance, and in clubs where you want the ball to stop on the green due to backspin, use a metal face material. It is better to keep track of it, and if you can adjust the face material and loft angle etc. according to the physical condition of the day and the characteristics of each person's swing for each count, golf will be easier, but in the past the face material is free Or replace it with
It was not possible to change the loft angle etc. by the face material to be attached.

Therefore, the present invention provides a golf club head in which the face member can be replaced according to the taste and swing of the golfer, the physical condition of the day, the condition of the golf course, and the like, and the loft angle and the like can be adjusted. The purpose is to do.

[0005]

In order to achieve the above object, according to the present invention, a face material constituting a golf club head is formed by a member different from the head body, and the face material can be replaced with respect to the head body. It is what

[0006]

Function: By preparing face materials made of various materials, the face materials can be replaced depending on the physical condition of the day. Further, by changing the thickness of the face material up and down, the loft angle can be changed depending on the face material attached to the head body.

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

In the embodiment shown in FIG. 1, a head body 1 integrally formed with a neck portion 2 into which a shaft (not shown) is inserted has a cavity 3 formed therein, and a screw hole 5 for attaching a face member 4 thereto. Has been formed. The face material 4 is formed as a member separate from the head body 1, and the head body 1
A screw hole 6 is formed at a location corresponding to the screw hole 5 of FIG.
The face member 4 is attached to the head body 1 with the screw 7. In this way, the face material 4 is attached to the head body 1
A vertical cross-sectional view of the state of being attached to is as shown in FIG. Lead, tungsten or the like can be put in the space 3 formed in the head body 1 for balance adjustment.

As a material for forming the head main body 1, stainless steel, aluminum, titanium alloy, copper alloy or the like, carbon fiber reinforced resin, resin, ceramic or the like can be used. Further, as the material for forming the face material 4, carbon fiber reinforced resin, copper, aluminum, titanium alloy or the like can be used. The thickness of face material 4 is 1 mm
In case of, the goose of the head body 1 is -1mm from the standard value.
There is. Therefore, the goose can be changed depending on the thickness of the face material 4.

In the second embodiment shown in FIG. 3, the head body 1
A groove 8 into which the face material 4 is fitted is formed, and the face material 4 is fitted into the groove 8 and then the face material 4 is fixed to the head body 1 with a screw 7 from the back side of the head body 1. is there.

In the above-described embodiment, the face member 4 is fixed to the head main body 1 with screws, but the face member 4 is simply
It is also possible to fit the head member 1 to the head body 1 or to attach and detach the face member 4 by using a fastener.

In FIG. 4, the thickness of the face member 4 is changed vertically. In this example, the lower end side is formed thicker than the upper end side so that adjustment can be made within ± 0.5 ° from the standard loft angle. I am doing it. In this example, if the angle α is 0.5 °, the 0.5 ° loft angle becomes larger than the standard loft angle. When the loft angle is ± 2 ° or more, the meaning of changing between the same counts becomes weak. Therefore, about ± 0.5 ° is preferable. Also, the thickness of the face material 4 is about 1 to 2 mm,
It is preferable to change the goose within a range of ± 3 mm with respect to the standard value. When the goose is set to +3 mm or more, there is a problem in head balance, and when it is -3 mm or less, it is a problem in strength.
When the thickness of the face material 4 is about 1 to 2 mm, the total thickness of the upper end side of the head is about 3 to 4 mm. In the embodiment shown in FIGS. 1 and 2, a hollow portion (void) is formed inside the head.
Although 3 is provided, it may be solid or may have a so-called cavity back shape in which a recess is formed on the back side. In addition, in each of the illustrated embodiments, an example of an iron club head is shown, but a face material can also be replaceably attached to a wood club head.

[0013]

As described above, according to the present invention, the face material forming the head is formed of a member different from the head body, and the face material can be replaced with respect to the head body. The face material can be replaced if necessary, and fine adjustment can be easily performed according to the physical condition and taste of the golfer. It is also possible to finely adjust the goose degree and the loft angle by changing the thickness of the face material or the thickness of the face material.
