Description
- This application is a continuation in part application of United States patent application filed on Aug. 3, 2018 and having application Ser. No. 16/054,159, the entire contents of which are hereby incorporated herein by reference.
- 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.
- 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.
- 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.
- 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 a longer distance.
- The head comprises a club head, a face pane, a shaft, a shock-proof component, and an anti-impulse component. The club head forms an opening and a through hole on two opposite sides of the club head, respectively. The face panel is securely mounted on the opening of the club head. The shaft is securely mounted in the through hole of the club head and forms a cavity. The cavity includes a bottom surface. The shock-proof component is mounted in the cavity of the shaft and comprises a first surface and a second surface. The first surface abuts the bottom surface of the cavity. The second surface is opposite the first surface. The anti-impulse component is mounted in the cavity of the shaft and comprises a third surface and a fourth surface. The third surface abuts the second surface of the shock-proof component. The fourth surface abuts an inner surface of the face panel.
- After the head hits a golf, the impulse may make the face panel concave inward and the golf is stuck away and deformed, too. Meanwhile, the impulse become shock waves on the head. Some shock waves will be transmitted to the anti-impulse component via the face panel and some shock waves will be transmitted to the shaft via the through hole, which is opposite the face panel, of the club head. The shock waves on the shaft are obstructed by the shock-proof component, so said shock waves may not be absorbed by the anti-impulse component. Therefore, all of the remaining impulse and the shock waves on the face panel can be absorbed by the anti-impulse component, and thereby the coefficient of restitution of the head is improved and thereby the golf may be hit away distantly.

FIG. 9 toFIG. 12 . The fifth embodiment of the present invention is provided. The differences between the fifth embodiment and the previous embodiments are described as follows. In the fifth embodiment, the head of a golf club comprises aclub head 10D, aface panel 20D, ashaft 30D, a shock-proof component 40D, and ananti-impulse component 50D. Theclub head 10D forms anopening 11 and an installing seat on two opposite sides of the club head. The installing seat forms a throughhole 12D. In this embodiment, the installing seat further forms a first stepped surface 120 in the throughhole 12D. Theface panel 20D is mounted on theopening 11 and theclub head 10D. Theshaft 30D comprises acolumn component 31D, and selectively comprises aweight adjusting component 32D and/or alead weight component 33D. Thecolumn component 31D has a first end and a second end opposite to each other. The first end closes to theopening 11 of theclub head 10D and the second end is securely mounted on the throughhole 12D of theclub head 10D. For example, the second end of theshaft 30D may be screwed in the throughhole 12. In this embodiment, theshaft 30D further comprises aflange 311D. Theflange 311D is formed at the second end of thecolumn component 31D. Theflange 311D is configured to abut the first stepped surface 120 and thereby a position of thecolumn component 31D is assured, which prevents thecolumn component 31D from being mounted too close to theopening 11 of theclub head 10D. - The
column component 31D may be a hollow body and thus a portion of a hollow space in thecolumn component 31D is configured as a receiving space and another portion of the hollow space is configured as a through-mounted space. Thecolumn component 31D may have a second steppedsurface 312D formed therein. The receiving space and the through-mounted space are divided by the second steppedsurface 312D. - The
weight adjusting component 32D is securely mounted in the through-mounted space of thecolumn component 31D; for example, theweight adjusting component 32D is screwed in the through-mounted space. With theweight adjusting component 32D, the total weight of the head is increased. Precisely, since theclub head 10D is hollow, theweight adjusting component 32D is configured to offset the weight lose because of casting, and thereby the head complies with the weight requirement. Theweight adjusting component 32D has an abutting surface aligned to the second steppedsurface 312D. Therefore, the receiving space is configured as a cavity, and the abutting surface of theweight adjusting component 32D and the second steppedsurface 312D are configured as a bottom surface of the cavity. However, it is not limited thereto. In another embodiment without the second steppedsurface 312D, the abutting surface ofweight adjusting component 32D is configured as the bottom surface of the cavity. - The
lead weight component 33D is securely mounted in the through-mounted space of thecolumn component 31D; for example, thelead weight component 33D is screwed in the through-mounted space of thecolumn component 31D. The location of thelead weight component 33D with respect to thecolumn component 31D is adjustable, and thereby a center of gravity of the head is controllable so that the head is suitable for the player. - The shock-
proof component 40D and theanti-impulse component 50D are mounted in the cavity of theshaft 30D. The shock-proof component 40D has a first surface and a second surface opposite to each other and theanti-impulse component 50D has a third surface and a fourth surface opposite to each other. The first surface of the shock-proof component 40D abuts the bottom surface of the cavity, i.e. the second steppedsurface 312D and the abutting surface of theweight adjusting component 32D. However, in another embodiment without theweight adjusting component 32D, the first surface may only abut on the second steppedsurface 312D; in another embodiment without the second steppedsurface 312D, the first surface may only abut on the abutting surface of theweight adjusting component 32D. The third surface of theanti-impulse component 50D abuts the second surface of the shock-proof component 40D and the fourth surface of theanti-impulse component 50D abuts the inner surface of theface panel 20D. The shock-proof component 40D may be made from silicone and theanti-impulse component 50D may be made from Thermoplastic Elastomer, i.e., TPE, but it is not limited thereto. In some embodiment, theanti-impulse component 50D in the fifth embodiment may be the buffer element in the previous embodiments, but it is not limited thereto. - After the head hits a golf, the impulse may become shock waves on the entire head. Some of the shock waves will be transmitted to the
anti-impulse component 50D via theface panel 20D and theshaft 30D via theface panel 20D and the throughhole 12D, which is opposite theface panel 20D, of theclub head 10D. The shock waves transmitted to theshaft 30D will be obstructed by the shock-proof component 40D, so the shock waves may not be transmitted to theanti-impulse component 50D via theshaft 30D, which allows theanti-impulse component 50D to absorb all the remaining impulse and the remaining shock waves on theface panel 20D. If the shock-proof component 40D only obstructs but does not absorb the shock waves, the golf is hit away while the shock waves are transmitted back to theface panel 20D, so the elasticity of theface panel 20D will not be affected. Besides, after the head hits a golf, theface panel 20D may deform inward and press theanti-impulse component 50D. Because theanti-impulse component 50D is supported by theshaft 30D and the shock-proof component 40D, theanti-impulse component 50D can help theface panel 20D to restore the original shape immediately. Therefore, the coefficient of restitution of the head is improved and thereby the golf may be hit away distantly and the player's demands can be achieved. - Moreover, in this embodiment, the
anti-impulse component 50D may comprise ananti-impulse recession 500D formed on the third surface and concaved away from the shock-proof component 40D. Similarly, theweight adjusting component 32D may comprise a adjustingrecession 320D formed on the abutting surface and concaved away from the shock-proof component 40D. Therefore, a contact area of the shock-proof component 40D and theanti-impulse component 50D or a contact area of the shock-proof component 40D and theweight adjusting component 32D is decreased, which avoids the shock waves on the entire head, except for theface panel 20D, being transmitted to theanti-impulse component 50D via the shock-proof component 40D, so that theanti-impulse component 50D can absorb the remaining shock waves on the face panel 20De and thereby the coefficient of restitution of the head is improved further and the golf will be hit away distantly. - Please refer to
FIG. 13 also. In another embodiment, the anti-impulse component may not comprise said anti-impulse recession, but the recession is formed on the shock-proof component 40D′ instead. Precisely, the shock-proof component 40D′ may comprise a shock-proof recession 400D′ formed on the second surface of the shock-proof component 40D′ and concaved away from the anti-impulse component. Similarly, the shock-proof recession may be formed on the first surface of the shock-proof component, or two of the shock-proof recessions are formed on the first surface and the second surface of the shock-proof component respectively. Furthermore, the shock-proof component may have a channel formed through the first surface and the second surface of the shock-proof component. - Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
