[Embodiment of the invention]

 (First Embodiment of the Present Invention) Hereinafter, a golf club according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. In the present embodiment, an example applied to the case of a putter will be described. FIG. 1 is an explanatory diagram of a schematic configuration of a main part of a golf club according to the present embodiment, FIG. 2 is a front view of a swing state using the golf club according to the present embodiment, and FIG. FIG. 4 is a perspective view of a golf club according to the present embodiment in a swing state, FIG. 4 is an explanatory view of a guide line arrangement on the upper surface of the head of the golf club according to the present embodiment, and FIG. FIG. 5 shows a view of a swing operation seen. As shown in the drawings, the golf club 1 according to the present embodiment has a configuration in which a plurality of guide lines 3 orthogonal to the upper edge of the face 2a are formed in parallel on the upper surface of the head 2.

The guide line 3 projects an arcuate virtual line passing through the face 2 a of the head 2 around the swing rotation axis in a predetermined club swing centering on the shoulder toward the player's viewpoint in the direction of the player's viewpoint. This is a configuration formed in a different arrangement. One of the guide lines 3 is formed to have a narrow predetermined width and a predetermined depth in a depth direction corresponding to a line of sight looking at the head side of the player in the predetermined club swing, and the bottom surface can be identified. It is composed of a groove 3a which is colored in the following manner.

Hereinafter, the arrangement of the guide lines 3 will be described. In a natural swing in which the player 10 grasps the ball 4 substantially vertically downward with a line of sight, as shown in FIG. 2, the swing surface is inclined from the ground or floor by 75 ° to 80 °. Then, in order for the line on the head 2 to form a continuous linear trajectory with respect to the rotation center axis of the swing by the swing, it is necessary that the direction of the line with respect to the line of sight of the player 10 does not change. . The direction of the line of sight of the player 10 with respect to the head 2 is substantially perpendicular to the upper surface of the head in the case of a putter.

Here, an arc-shaped imaginary line passing through the face 2a of the head 2 and centered on the swing rotation axis is always continuous as an elliptical arc locus from the viewpoint of the player 10 substantially on the rotation axis during the swing. You can see it.

When the virtual line is projected on the upper surface of the head 2 in the direction of the viewpoint of the player 10 (see FIG. 4), a substantially arc-shaped guide line 3 is formed on the upper surface of the head 2. When viewed from the viewpoint, a continuous trajectory can always be drawn (see Fig. 5).

On the other hand, the groove 3a is formed such that the depth direction of the groove is substantially parallel to the direction of the line of sight of the player 10 with respect to the head 2 (see FIG. 4A). The bottom is visible. By swinging so that all the guide lines 3 including the groove bottom part are always visible, the head 2 can be moved in a correct trajectory, and the swing can be easily and accurately swinged.

Next, a swing operation of the golf club based on the above configuration will be described. First, the player 10 stands parallel to the target line toward the target, positions the viewpoint vertically above the head, and adjusts the inclination of the head so that all the guide lines 3 on the upper surface of the head 2 can be seen to create a correct address state. When a natural inside-to-inside swing is performed around the shoulder, the guide line 3 has a continuous trajectory due to an afterimage effect. By repeating this several times, the size of the arc-shaped head trajectory (the size of the takeback and the follow swing) corresponding to the distance to the target is imagined.

After that, the player 10 places the ball 4 at a predetermined position on the front face, and sets the correct address state as described above, and sets the ball 4 in a natural inside position with the shoulder at the center according to the size of the imaged arc-shaped head locus.・ If you hit the ball 4 by performing a to inside swing, the ball 4 will advance to the target.

As described above, in the golf club according to the present embodiment, the guide line 3 is formed by projecting the virtual line that appears to draw a continuous trajectory from the viewpoint of the player 10 on the upper surface of the head 2. By forming a groove 3a that allows the bottom of the groove to be seen as a guide line when viewed from the line of sight with a correct form as a part of the guide line, the guide line 3 can be accurately swung from the viewpoint of the player 10 due to an afterimage effect. Since the trajectory can be seen as a substantially arc-shaped trajectory similar to the virtual line, the guide line 3 can be used as a guide without giving a sense of incongruity. By moving and swinging according to the image, you can make a natural and reasonable swing and hit the ball accurately.

The head trajectory seen from the viewpoint of the player is elliptical, but in the vicinity of the impact, the trajectory is very close to a perfect circular arc. The radius of the circle is about 5 m, although there are various putters. On the other hand, in the case of wood, it is about 4 m.

(Second Embodiment of the Present Invention) Hereinafter, a golf club according to a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is an explanatory diagram of a schematic configuration of a main part of the golf club according to the present embodiment.

As shown in FIG. 6, the golf club 1 according to the present embodiment is different from the first embodiment in that the upper surface of the head 2 is formed in two stages, upper and lower, and a guide line 3 is provided. Are formed on each upper surface so as to be visible as a continuous line from the viewpoint of the player 10 in a predetermined club swing centered on the shoulder.

In the swing operation by the golf club based on the above configuration, similarly to the first embodiment, the player 10 stands in parallel with the target line toward the target, and all the guide lines 3 on the upper surface of the head 2 are continuous at the time of addressing. Move the head so that it is visible, make an actual swing according to the obtained image, and hit the ball 4. A natural swing centered on the shoulder can be performed, and the ball 4 can be hit with a reasonable and correct swing.

As described above, in the golf club according to the present embodiment, the upper surface of the head 2 is formed in a plurality of steps, and the guide line of each step can be viewed as a continuous line only from a predetermined direction that is a line of sight in a correct form. When the player 10 moves the head 2 so that the guide line can always be seen continuously at the time of addressing and swings according to the obtained image, the swing surface slightly tilts from the vertical surface, and the natural No You can hit the ball more accurately on a swing.

In the golf clubs according to the first and second embodiments, the guide wire 3 is applied to a general putter. It can also be applied to clubs. In a wood or iron, the line of sight of the player 10 with respect to the head 2 is inclined at a predetermined angle from the direction perpendicular to the ground, and is different from the putter described above. When the head 2 is moved so as to be seen and the swing is performed according to the obtained swing image, a natural swing centering on the shoulder can be performed as described above, and the ball can be hit accurately.

In the golf club according to each of the first and second embodiments, the guide line 3 is arranged such that an arc-shaped imaginary line is projected on the upper surface of the head 2 in the direction of the viewpoint of the player 10. However, when the club is a putter, the virtual line may be projected vertically upward as it is to form a substantially arc-shaped guide line on the upper surface of the head, so that the line of sight is almost vertical. On the top surface of the head, the guide line 3 is substantially the same as the guide line 3 in each of the above embodiments, and can be regarded as the same, and can be sufficiently substituted.

The golf club according to each of the first and second embodiments has a configuration in which the guide line 3 is formed on the upper surface of the head 2. In addition, FIG. 7 and FIG. As shown in the figure, a circular hole 5 is formed at a predetermined depth from the upper surface of the head 2 and the bottom surface of the hole 5 can be colored so as to be identifiable. When colored red, not only the right and left inclination of the head 2 but also the forward and backward inclination can be identified based on the appearance of the bottom of the hole, and an abnormal inclination of the head 2 due to an incorrect form can be easily determined. Furthermore, when the player 10 always moves the head 2 so that the hole bottom looks right at the address, and swings according to the obtained swing image, a natural swing centering on the shoulder can be performed as described above, and the ball can be accurately positioned. You can beat.
