[0004]
However, the golf club described in Patent Document 1 has a piezoelectric element disposed on the grip side of the shaft, and can control vibration transmitted to the grip due to impact at the time of impact, but stabilizes the directionality of the hit ball. On the other hand, since the distance between the grip and the head is long, the function of the piezoelectric element is not exerted to the tip side of the shaft, and the return speed of the shaft head becomes slow, which is unstable. It was.
Similarly, since the function of the piezoelectric element is not exerted up to the front end side of the shaft, it has been insufficient in terms of control to increase the flight distance of the hit ball by controlling the overall bending deformation.
[0005]
[Problems to be solved by the invention]
Accordingly, the present invention aims to provide a golf club head and a golf club using the head that solves this problem by suppressing an unpleasant vibration at the time of impact and improving the flight distance.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention employs the following technical means.
The technical means includes a golf club head (hereinafter referred to as “head”) comprising a piezoelectric element that converts a deformation force due to an impact into electric power and controls the vibration characteristics of the golf club head with the electric power. It is said). (Claim 1)
[0007]
According to the present invention, vibration at impact can be suppressed by the vibration characteristic control function of the piezoelectric element.
The piezoelectric element absorbs the deformation of the head due to the impact at the time of impact, and the repulsive force of the head against the ball is amplified by the electric power due to the deformation force, and this amplified repulsive force is converted into the kinetic energy of the ball and Improvement is realized.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The location where the piezoelectric element is disposed may be a location where the impact at the time of impact does not directly act on the piezoelectric element and the repulsive force acts on the ball. Preferably, the piezoelectric element is disposed on the crown portion. To do. (Claim 2)
In this case, the piezoelectric element is disposed over almost the entire crown portion. For example, if the main purpose is to suppress hooks and slices, the piezoelectric elements are disposed closer to the toe or closer to the heel. . (Claim 3)
Specifically, it is disposed closer to the toe for hook suppression and closer to the heel for slice suppression.
The piezoelectric element is disposed by being attached to the surface of the head or embedded in the head.
[0009]
The present invention can achieve the object by disposing only the piezoelectric element in the head. However, in order to make it more effective, it is preferable to include a piezoelectric circuit for controlling the piezoelectric element. (Claim 4)
That is, by adjusting the vibration characteristic control function of the piezoelectric element by the piezoelectric circuit, optimal vibration characteristic control can be performed for each golfer.
[0010]
According to the golf club using the head (claim 5), the above-described operational effects are obtained, and extremely high performance is achieved both in flight distance and directionality.
[0011]
The piezoelectric element referred to in the present invention is most preferably a substantially film-like element that can be deformed and conforms to the shape of the head so as not to impair the aerodynamic characteristics and design of the head.
Further, the piezoelectric circuit for controlling the piezoelectric element may be disposed on either the head side or the shaft side.
For example, when arranged on the head side, the head, the piezoelectric element, and the piezoelectric circuit form a single unit, so that the golf club can be assembled quickly and easily.
In this case, it is preferable that the piezoelectric circuit is embedded in a portion other than the face surface of the head in order to protect the piezoelectric circuit from impact.
Further, when arranged on the shaft side, the impact of the ball at the time of impact is smaller than that of the head, so that the protection performance of the piezoelectric circuit is excellent.
In addition, when arrange | positioning at the shaft side, it is preferable to incorporate in the site | part corresponding to the grip with the least deformation | transformation of a shaft.
[0012]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
1 and 2 show a golf club 2 of the present invention using the head 1 of the present invention.
In the figure, reference numeral 3 is a piezoelectric element, reference numeral 4 is a piezoelectric circuit, reference numeral 21 is a shaft, and reference numeral 22 is a grip.
[0013]
In the head 1 of this embodiment, the piezoelectric element 3 is disposed over substantially the entire surface of the crown portion 11.
A piezoelectric circuit 4 is embedded and disposed on the back side (opposite the face surface) of the head 1, and is electrically wired to the piezoelectric element 3 as shown in FIG.
The piezoelectric circuit 4 is disposed via a buffer material 41 in order to protect it from an impact at the time of impact.
In the drawing, the piezoelectric element 3 is shown exposed from the crown portion 11, but actually, the piezoelectric element 3 is hidden by the paint when the head 1 is painted.
Further, since the piezoelectric circuit 4 is well known in terms of circuit configuration for controlling the piezoelectric element, the description of the specific structure of the circuit is omitted.

By the way, the hitting ball becomes sliced or hooked by the golfer's swing trap.
As a cause of this, a slice ball or a hook ball is generated due to a lateral gear effect caused by friction between the face surface and the ball generated at the time of impact.
In this embodiment, by utilizing the vibration characteristic control function of the piezoelectric element, by causing the gear effect to act in the hook direction to the gear effect acting in the slicing direction or the hook direction, the force rotating in the direction of each other is offset, A more stable direction is realized.
[0015]
When the piezoelectric element 3 is disposed closer to the heel (FIG. 4A), the repulsive force of the part is amplified by the piezoelectric element, so that the gear effect acts to rotate the ball B in the hook direction. (Fig. 4 (b))
In other words, the embodiment shown in FIG. 4 is effective for a golfer having a swing rod that the hit ball slices.
On the other hand, when the piezoelectric element 3 is disposed close to the toe (FIG. 5A), the repulsive force of the part is amplified by the piezoelectric element, so that the gear effect causes the ball B to rotate in the slice direction. Act on. (Fig. 5 (b))
In other words, the embodiment shown in FIG. 5 is effective for a golfer having a swing rod that is hit by a hit ball.
