CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims priority under 35 U.S.C. 119 from Taiwan Patent Application No. 106128252 filed on Aug. 21, 2017, which is hereby specifically incorporated herein by this reference thereto.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a head of a golf club, especially to a head of a golf club with a high coefficient of restitution.

2. Description of the Prior Arts

A conventional golf club comprises a club and a head mounted on one end of the club. The head has a face panel mounted on one side of the head. The face panel has a specific thickness. A handle is formed on another end of the club. When a player grips the handle with hands and hits the golf, the golf club is swung and hits the golf at 45 meters per second, and the face panel with a coefficient of restitution approximately from 0.825 to 0.83 impacts the golf. At that time, the impact force makes the face panel slightly deform concavely by 0.2 to 0.25 millimeters at a striking point, and the golf also deforms by a reaction force and further, the golf pops out because of the reaction force.

According to experience and skill level, a golf player may be sorted as a professional golf player or an amateur. Besides, there are various types of golf clubs, one of which comprises a wood club with a hollow head, and this wood club is utilized to strike out for longer distances. A professional player can accurately adjust the hitting force and control movement in hitting the golf, so the professional player is able to strike out the golf to a longer desired distance. In contrast, an amateur cannot control movement and strike force as accurately as the professional player, so even using the same golf club and the same face panel, the amateur still cannot strike out the golf to the longer desired distance. In other words, the amateur using a conventional golf club may not reach a desired striking effect.

To overcome the shortcomings, the present invention provides a head of a golf club to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a head of a golf club, the head having a face panel with a high coefficient of restitution. With the face panel with a high coefficient of restitution, an amateur can easily strike out the golf for a long distance.

The head has a club head, a shaft, and a buffer element. The club head is a hollow body and has a face panel and an installing seat. The face panel is mounted on one side of the club head. The face panel is made of a board and has an inner surface and an outer surface. The installing seat is formed on another side of the club head and has a through hole communicating with an interior of the club head. The shaft is an elongated body, is mounted in the club head, and has a cavity and a mounting portion. The cavity is formed at one end of the shaft. The mounting portion is formed on another end of the shaft and securely mounted on the installing seat of the club head. The buffer element is a compressible and resilient body and has two ends. One of the ends of the buffer element is mounted in the cavity of the shaft, and an end surface of the other end of the buffer element abuts the inner surface of the face panel. An axis of a combination of the shaft and the buffer element is perpendicular to the inner surface of the face panel.

Therefore, as the shaft is mounted in the club head and the buffer element is mounted on the shaft and abuts the inner surface of the face panel, when the golf is hit by a golf club with aforesaid head, the outer surface of the face panel is impacted and deforms concavely and the golf is popped out immediately. Meanwhile, the compressible and resilient buffer element may conserve the impulse and prevent the face panel from splitting or breaking. Therefore, a thickness of the face panel may be lower than that of a conventional face panel and thereby increasing coefficient of restitution to pop out the golf for longer distance.

With the aforesaid structures, i.e. the shaft is mounted inside the club head, the buffer element is mounted on the shaft and adjacent to the face panel, and the buffer element abuts the inner surface of the face panel, when the golf is being hit, the outer surface of the face panel may deform concavely by the impulse and the golf may also deform at the same time so that the golf is struck out. Being a compressible and resilient body, the buffer element may conserve the impulse and prevent the face panel from being broken by the impulse. Therefore, a thicker face panel than a conventional face panel may be mounted on the head, and the head with a high coefficient of restitution may assist the golf to be struck out to a longer distance.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 1, 2, and 3, a head of a golf club in accordance with the present invention has a high coefficient of restitution. In a first embodiment, the head comprises a club head 10, a shaft 20, and a buffer element 30.

The club head 10 is a hollow body. The club head 10 has a face panel 11 mounted on one side of the club head 10. The face panel 11 is made of a board and has an inner surface 111 and an outer surface 112. The outer surface of the face panel 11 is configured to hit the golf. A thickness of the board is lower than that of the conventional, which makes the face panel 11 have a high coefficient of restitution. The club head 10 has an installing seat 12 formed on another side of the club head 10. The installing seat 12 comprises a through hole communicating with an interior of the club head 10.

The shaft 20 is an elongated body. The shaft 20 comprises a cavity 21 at one end of the elongated body and a mounting portion 22 at another end of the elongated body.

The buffer element 30 is a compressible, resilient, and elongated body. The buffer element 30 has two ends, one of the ends is mounted in and combined with the cavity 21 of the shaft 20, and thus axes of the combined shaft 20 and buffer element 30 are perpendicular to the inner surface 111 of the face panel 11. The other end of the buffer element 30 protrudes out of the shaft 20 and an end surface of the other end of the buffer element 30 abuts the inner surface 111 of the face panel 11. The shaft 20 is mounted into the club head 10 through the through hole of the installing seat 12. The mounting portion 22 is mounted on and combined with the installing seat 12 of the club head 10.

Then please refer to FIGS. 1 to 3. In this embodiment, the shaft 20 is a hollow tube. Therefore, the cavity 21 is formed at one end of the tube. An outer wall of the mounting portion 22 has outer threads 221 and the through hole of the installing seat 12 has inner threads, so that the outer threads 221 of the mounting portion 22 and the inner thread of the installing seat 12 are securely threaded together. One end of the elongated body (i.e. the shaft 20) forms a positioning sleeve 223, and the positioning sleeve 223 is utilized to abut an exterior of the installing seat 12; the end of the elongated body is said another end comprising the mounting portion 22.

Then please also refer to FIG. 4. When a user swings the golf club and hits a golf, the face panel 11 of the club head 10 strikes the golf 40. Meanwhile, the outer surface 112 of the face panel 11 is impacted and deformed slightly and concavely. Because the inner surface 111 of the face panel 11 is abutted and supported by the resilient buffer element 30, the face panel 11 may not over deform to split or break but is capable of reverting to the original shape after hitting the golf.

The first embodiment of the present invention further comprises a cap 50.
