【Example】

(First Embodiment) FIG. 1 is a front view showing a usage state of a golf club according to this embodiment, FIG. 2 is a plan view of the same, FIG. 3 is an enlarged front view of a main part of a club head, and FIG. 4 is a side view of the same. An embodiment of the present invention will be described below with reference to the accompanying drawings.

First, the basic structure of the golf club A will be described below.

As shown in FIGS. 1 to 4, a golf club A according to this embodiment has a club head 1 having a face 3 serving as a ball striking face formed on the front surface, and a tip end connected to a base end of the head 1. However, the shaft 2 having the grip 4 on the base end side is provided.

Reference numeral 5 denotes a so-called socket shaft joint portion, which is integrally formed with the outer end portion 1a which is the base end of the club head 1 at the time of addressing. In addition, as shown in FIG. 2, the shaft 2 connected to the shaft joint portion 5 is formed so that the axis X of the shaft 2 is bent and inclined toward the inner end 1b (tip) side of the club head 1 and viewed from a side view (striking ball). When viewed from the direction), the angle formed by the shaft 2 and the club head 1 is an acute angle, and the club head 1 and the shaft 2 are configured so as to overlap each other in plan view as shown in FIG.

In other words, when the player M addresses with the grip 4 of the golf club A, the club joint 5 is provided at the outer end 1a farther from the player M (see FIG. 1). ).

Therefore, at the time of address, the club head 1 directs the toe (tip) toward the player M side, and
The heel (proximal end) is located on the opposite side, and compared with a normal club, there are differences such as a hoe and a plow, and the shapes are greatly different.

Further, the center of gravity of the club head 1 is also moved to the front side in the address state plan view, that is, to the inside of the shaft 2 (player M side) as compared with a normal club, and the backswing, top of swing, etc. Then
The way in which the weight of the club head 1 is transmitted to the hands and arms is different from that of a general club.

By the way, the angle formed by the shaft 2 and the horizontal ground, the so-called lie angle α, can be appropriately selected within the same range as that of a general club of 35 ° to 65 °. In the golf club 1 according to the present embodiment, as described above, the angle formed by the shaft 2 and the club head 1 matches.

The club head 1 has a so-called iron structure in which a metal such as soft iron or stainless steel is formed into a plate shape. In the present embodiment, as shown in FIG. 4, the loft, which is the angle β at which the face 3 of the club head 1 rises with respect to the horizontal ground, corresponds to a normal iron number 3 iron.

In FIGS. 1 to 3, 3a is a fine groove formed on the face 3 called a plurality of score lines, and B is a golf ball.

In the golf club A having the above structure, the gist of the present invention is to provide a mark 7 on the top or back of the club head 1 and to allow the same mark 7 to be seen from the player M in a proper address posture. It is located so as to be hidden by 2. The club head 1
The top portion or the back portion of the face 3 refers to all the positions located behind the face 3 including the upper end face of the face 3.

That is, as shown in FIG. 2, in this embodiment, a triangular mark 7 is provided at the top of the club head 1 of the golf club A, a so-called leading edge, and the mark 7 is a regular mark. In the address posture of, the player 2 hides the shaft 2 as seen from the player M.

By providing the mark 7, the player M can easily take a correct correct address posture in golf swing.

That is, in the address posture shown in FIG. 1, when the mark 7 is arranged so as to be hidden by the shaft 2 as shown in FIG. 2, the position of the grip 4 and the position of the head of the player M are set correctly. Therefore, it is possible to easily take the correct address posture which is the basis of the golf swing.

Moreover, in the present golf club A, since the toe of the club head 1 faces the player M side, when the club head 1 is viewed from the player M side, the shaft 2 appears to overlap with the club head 1, so that the face There is an advantage that 3 can be easily fitted to the square in the flight direction. Moreover, the set position of the ball B is not limited to the face 3 as well.
Since the shaft 2 can be used as a reference, it becomes easy to set the shaft 2 at a fixed position.

In the subsequent take-back operation, if the club head 1 reaches the height of the waist of the player M, the mark 7 is always hidden by the shaft 2 as seen from the player M. Good.

For example, if the position of the grip 4 is the player M
When reaching the waist of the player M, the face 3 is facing the front of the player M, which is the correct midpoint of the backswing. At this time, in the golf club A according to the present invention,
Since the tip of the club head 1 faces downward, it is easy to visually recognize, and since the mark 7 serving as a guide is provided, it is easy to perform correct takeback.

In the conventional club, the club head 1
Is projected at a position farther than the player M with respect to the tip of the shaft 2, the rotational moment is larger at the center of gravity of the club head 1 than at the tip of the shaft 2, and unnecessary at the grip 4. Even if the movement of the hand is subtle, it is easily transmitted to the club head 1, which is a major cause of the orientation of the face 3 deviating. However, in the present golf club A, the club head 1 is positioned relative to the tip of the shaft 2. Therefore, at the center of gravity of the club head 1, the rotational moment becomes smaller than that of the tip of the shaft 2, and the club head 1
This has the advantage of reducing unnecessary movements of.

Further, in the process of shifting from takeback to backswing, the club head 1 remains in a state where the toe hangs downward, that is, the center of gravity of the club head 1 is located below the tip of the shaft 2. Since the takeback can be taken, the sense of stability of the club head 1 is increased, the correct takeback can be easily taken without changing the direction of the face 3, and the backswing can be smoothed.

As described above, by providing the mark 7 at the position where the toe faces the player M side and is hidden by the shaft 2 when viewed from the player M side, correct address and take back can be easily obtained. By repeating such practice, the correct address posture and take back can be naturally acquired.

Conventionally, whether or not a correct golf swing, especially a correct address and takeback has been made, depends on the eyes of another person, or VT is required for confirmation by oneself.
Although it was confirmed after finishing the swing at R etc., in the present golf club A, since it can be performed while checking the mark 7 with one's own eyes, rational practice is possible.

Depending on the club count (for example,
Nos. 6 to 9, pitching wedges, sand wedges, etc.) and marks 7 may be provided on the face 3.

Although the mark 7 has a triangular shape in this embodiment, it may have any shape as long as it can be recognized. Further, the method of applying the mark 7 to the club head 1 such as coloring or engraving can be appropriately selected.

(Second Embodiment) Next, as a second embodiment, a golf club A shown in FIG. 5 will be described.

This is one in which the sole portion (bottom portion) 11 of the club head 1 is formed so as to project to the back side, and a mark 7 is provided on the upper surface of the sole portion 11 and serves as the top portion of the club head 1. Since there is more area than the so-called leading edge, there is an advantage that the mark 7 is provided and it is cheap.

(Third Embodiment) FIG. 6 shows a so-called driver, spoon, etc. in which the club head 1 described above is replaced with an iron club to form a wood club.

Since such a wood club has a wide surface on the top of the club head 1, it is possible to appropriately design the mark 7 by providing a plurality of marks 7 in a line as shown in FIG.

(Fourth Embodiment) The one shown in FIG. 7 is a so-called putter, and the shape of the club head 1 has various shapes as compared with irons and woods. By providing a mark 7 on the top of the club head 1 or on the back depending on the shape of the club head, by holding the mark 7 so as to be hidden by the shaft 2 even when putting, it is possible to take an address that facilitates accurate putting. You can

[0037]

According to the present invention, the following effects can be obtained.

The base end of a club head having an arbitrary loft and having a face serving as a ball striking face on the front surface is connected and fixed to the front end of the shaft having a grip on the base end side. By providing a mark on the top or back of the club head in the golf club facing the player in the regular address posture, and locating the mark so as to be hidden by the shaft when viewed from the player in the regular address posture. Since the position of the grip and the position of the player's head are set correctly, it is possible to easily take the correct address posture which is the basis of the golf swing.

Moreover, since the toe of the club head faces the player M side in this golf club, when the club head is seen from the player side, the shaft appears to overlap with the club head, and thus the face is squared in the flight direction. Easy to match. Moreover, since the ball can be set not only on the face but also on the shaft, it becomes easy to set the ball at a fixed position.

In the subsequent take-back operation, it is sufficient that the mark is always hidden by the shaft as seen from the player until the club head reaches the waist height of the player. Easy to do.
