Abstract

PROBLEM TO BE SOLVED: To increase the repulsive force of a ball at the time of ball hitting and to widely assure a sweet spot by forming a space between the faces of a head and supporting the faces via a spring material or elastic material housed in the space. SOLUTION: The recessed space 5 is formed on the ball hitting surface of the wooden head 2 and after the spring material or elastic material 3 is housed in this space 5, the face 3 made of metal or ceramics is mounted thereto. Pressure is uniformly acted with good balance on the face 3 at the time of ball hitting, by which the repulsive force may be increased and the sweet spot may be widened according thereto. The metallic sounds produced when the ball is hit are silenced and impact is absorbed by the elastic material 3 compressed at the time of ball hitting and, therefore, a soft touch is obtained and the run- out of the head is prevented. Directivity may thus be stabilized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a method of compressing and attaching a spring material or elastic material between a metal or ceramic face formed on a surface of a wooden head hitting a ball, Pressure is uniformly applied to the face in a well-balanced manner, increasing the resilience and widening the sweet spot. The compressed elastic material eliminates the metallic sound generated when the face catches the ball and absorbs the impact, so the feel is soft, the head does not swing, and the directional performance is determined. The present invention also relates to a face of a grand golf club, which protects wooden dents and metal distortions by using the elastic material, and also has a function of maintaining and maintaining performance.

2. Description of the Related Art A conventional golf club head has a synthetic resin face attached to a wooden head, but since the head is integrated, an impact is transmitted directly and the head is likely to touch. Further, since the soft and hard materials are bonded together, the head is depressed, the face is easily distorted, and a problem occurs in the bonding surface.

[Problems to be Solved by the Invention] In order to eliminate the drawback, a spring or elastic material is compressed and attached between a wooden head, a metal or ceramic face and the face is attached. In addition, the pressure is uniformly applied in a well-balanced manner, the repulsion is increased, and the sweet spot is widened. Another object of the present invention is to develop a head for a grand golf club, which has a function of preventing wooden dents and metal distortion and dents by using elastic materials and having a function of maintaining performance for a long time.

[Means for Solving the Problems] The means for solving the problems will be described with reference to the drawings. (2) The surface of the wooden head hitting the ball is (3) between the metal or ceramic face. (4) Compress and attach spring material or elastic material.

[Operation] The structure described above is used to compress a spring or elastic material between a metal or ceramic face formed on the surface of a wooden head hitting a ball. By attaching: The face is evenly and evenly pressured, the iron repulsion is further enhanced, and the sweet spot widens. 2. 2. The compressed elastic material eliminates the metallic sound generated when the ball is caught and absorbs the impact, resulting in a soft feel, and the head is not touched and the directional performance is determined. Elastics protect wooden cavities and metal distortions and provide long lasting performance. 4. When you take it straight, you can understand the difference in sound.

[Embodiment] The present invention is applied not only to a grand golf club but also to a head of a golf club, a Malay golf, a park golf, etc., and also to a skeck of a gate ball.
In addition, the materials of the head and the face are not limited to those described above, and can be made of other various materials.

[Effect of the Invention] Since the sweet spot can be widely taken, even if it deviates from the core, the damage is small.

[0001] In the present invention, the repulsive force is enhanced by forming a space between a wooden head and a metal or ceramic face. or,
A spring or resilient material is press-fitted into the space between the metal or ceramic face formed on the surface where the wooden head hits the ball, and the face is evenly balanced and pressure is applied. And the sweet spot becomes wider. When the face catches the ball due to the spring material or the elastic material pressed in,
Since the generated metal noise is eliminated and the impact is absorbed, the feel when hit is soft, the head does not swing, and the directional performance is determined. Also, the present invention relates to a head of a grand golf club, which protects the movement of the head and the distortion of the face by using the spring material or the elastic material, and also has a function of maintaining the performance for a long time.

2. Description of the Related Art A conventional golf club head has a synthetic resin face attached to a wooden head, but since the head is integrated, the impact is transmitted directly and the head is likely to touch. In addition, since different materials such as wood and synthetic resin are bonded together, a difference in movement acts between the head and the face, and the head and the face are easily peeled off by an impact, thus causing a problem on the bonding surface.

[Problems to be Solved by the Invention] In order to eliminate the drawback, a space is formed between a wooden head and a metal or ceramic face. Alternatively, a spring material or an elastic material is press-fitted into the space and attached to the face, whereby pressure is uniformly applied to the face in a well-balanced manner, rebound force is increased, and a sweet spot is widened. or,
With a wooden head by spring material or elastic material,
An object of the present invention is to develop a head of a grand golf club having a feature of protecting a difference in movement of a metal or ceramic face and maintaining the performance for a long time.

[Operation] The above structure is used. By using this structure, a spring material or a resilient material is pressed into a space between a metal or ceramic face formed on a surface of a wooden head hitting a ball. Then, by attaching, Pressure is uniformly applied to the face in a well-balanced manner, and the repulsive force of the metal or ceramic is further enhanced. 2. (Same sentence as before) The spring or elastic material protects the difference between the movement of the wooden head and the metal or ceramic face, and works to maintain the performance of both. Even when used only in the space between the head and the face, the resilience is enhanced and the impact transmitted to the body is small.

[Embodiment] There is also a method of using a head having only a space formed between the head and the face, and a head in which a spring material or elastic wood is press-fitted and mounted in the space between the head and the face. In addition to the grand golf club, the present invention is also applied to a golf club, a gate ball, a mallet golf club, and a park golf club. In addition, the material of the head and the face is not limited to wood and metal or ceramics, and can be made by combining various other materials, and can be used alone.

[Effect of the Invention] The repulsion force is enhanced by the space between the head and the face, and the sweet spot is widened.
Also, since the material is compressed by pressing a spring or elastic material into the space between the head and the face, the face is always in a detached state, and to absorb the impact force when hitting the ball The head does not swing. It also acts as a cushion between the head and the face, protects the difference in movement between the two, and is difficult to break because it lasts a long time.
