Abstract

PROBLEM TO BE SOLVED: To provide an iron golf club head which gives high impact resilience especially and can absorb the vibration of a strike.SOLUTION: There is provided an iron golf club head which comprises: a club head body where a chamber is formed in the inner part and a fitting recessed part which communicates with the chamber is formed in the front; and a face plate where a face surface is formed in the front, and which fits into the fitting recessed part of the club head body. The face surface is made flat to the front of the club head and seals the chamber of the club head body.

Description

  The present invention relates to a golf tool, and more particularly to an iron golf club head.

The existing iron club head mainly includes a club head main body and a face plate installed on the front surface of the club head main body, and a balance weight portion for appropriately adding weight is installed at the bottom of the club head main body. A club connecting portion extending obliquely upward is formed on one side of the club head main body, and the iron club head is bonded to the shaft by the club connecting portion to constitute an iron golf club. When the user swings while holding the iron golf club in his hand, he can hit the ball with the face plate.
When the iron club head strikes, the club head vibrates and becomes unstable, and in order to improve the stability of the ball control while solving the problem of the vibration, the back surface of the club head body of the iron club head A shock absorbing member having an airbag is attached, and the shock absorbing member is attached to the back surface of the face plate.

Taiwan Utility Model No. M383430

  However, in the existing iron club head, an impact absorbing member having an airbag is attached to the back surface of the face plate, and the impact absorbing member can absorb an impact when hit by the airbag. Is attached to the back surface of the face plate, the thickness of the hitting portion of the iron club head increases, and the shock absorbing member disperses the force on the face plate. Therefore, when hitting with an iron club head, there is a problem that the deformation amount of the face plate is reduced and the resilience is lowered.

An iron golf club head according to the present invention has a club head body in which a chamber is formed and a fitting recess communicating with the chamber is formed on a front surface.
The front surface of the club head body is flattened on the front surface, a face surface for sealing the chamber of the club head body is formed, and a face plate is fitted into the fitting recess of the club head body.

  In such an iron golf club head, it is preferable that the club head body is made of stainless steel or carbon steel, and the face plate is made of high-strength steel, maraging steel or spring steel.

  In such an iron golf club head, the depth of the chamber of the club head body in the front-rear direction is preferably 0.5 mm to 2.5 mm, and the thickness of the face plate is preferably 1.5 mm to 2.8 mm.

  Due to the above-described structure, when the iron club head of the present invention is used, the face plate receives an impact force hitting a ball and generates elastic deformation toward the chamber of the club head body. Since the fold or deformed part moves slightly into the chamber, the chamber provides its storage space. For this reason, the face plate can provide high resilience when striking with a sufficient amount of elasticity, and can reduce vibration when striking with the chamber.

1 is a perspective view of an embodiment of an iron golf club according to the present invention. 1 is a plan view of an embodiment of an iron golf club according to the present invention. FIG. 3 is a cross-sectional view taken along line 3-3 in FIG. 2. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side sectional view showing a hitting state in an iron golf club according to the present invention.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 1 to 3, the iron golf club head embodiment of the present invention includes a club head body 10 and a face plate 20.

  As shown in FIG. 3, the club head main body 10 is formed by casting or forging with a stainless steel or carbon steel material, and a chamber 11 is formed inside the club head main body 10. The depth (w) in the front-rear direction is preferably 0.5 mm to 2.5 mm, and a fitting recess 12 communicating with the chamber 11 is formed on the front surface of the club head main body 10, and the depth of the fitting recess 12 is The face plate 20 is formed to be fitted, and the peripheral portion of the fitting recess 12 extends from the outer periphery of the chamber 11. A club connection portion 13 extending obliquely upward is formed on one side of the club head main body 10, and a balance weight portion 14 is provided on the bottom of the club head main body 10.

  As shown in FIG. 3, the face plate 20 is a highly elastic and steel plate made of a material such as high-strength steel, maraging steel, or spring steel. It is fitted in the fitting recess 12. The front surface of the face plate 20 is a face surface, and the face surface is flat with the front surface of the club head main body 10 to seal the chamber 11. The thickness (t) of the face plate 20 is preferably 1.5 mm to 2.8 mm. The face plate 20 and the club head main body 10 are made of a steel material, and are bonded together by welding means, and surface processing (such as polishing) is performed to constitute an iron club head.

  As shown in FIG. 4, the iron club head according to the present invention is bonded to a shaft via a club connecting portion 13 to constitute an iron golf club. When the user swings while holding the iron golf club, when the face plate 20 hits the ball 30, the face plate 20 receives an impact force and elastically deforms toward the chamber 11 of the club head body 10. Produce.

  At this time, the bent or deformed portion of the face plate 20 slightly moves to the chamber 11, so that the chamber 11 provides the storage space. According to this, the face plate 20 accumulates enough elasticity to give the ball 30 high resilience when hit, and reduces vibration when hit by the sealed chamber 11 of the club head body 10. be able to.
