Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club capable of stably launching a ball at a sweet spot.

[0002]

2. Description of the Related Art In the course of golf play, it is most important to catch and launch a ball at a sweet spot on a club face when the ball is launched, but the sweet spot is located in the club face at the end of a long shaft. Aside from the narrow part, it was not easy for beginners and intermediates to reliably hit the ball at the sweet spot in the quick swing movements.

[0003] For this reason, a club that can easily catch the ball at the sweet spot is desired. In many cases, the launch of the ball at the sweet spot should be solved by the skill of each player. In the above, only the clubs provided with the aim of achieving the flight distance and high trajectory by each club were provided.

[0004] However, it is needless to say that they are also premised on launching the ball at the sweet spot, and in order to achieve the most important thing in this first stage, the club has to use a sweet spot. Many pursued the ease of catching the ball at the spot, but most depended on the skills of the players, and did not achieve sufficient results.

[0005] In such a situation, a club in which the psychological action at the time of hitting is applied to a club configuration as a club which can easily launch a ball at a sweet spot, has some problems while leaving some problems. There were no achievements. For details, refer to the literature (1996 Patent Application No. 2554).
No. 26), the gist of which will be reprinted below.

[0006] As an example, taking actual play, when a player sees a pond or a valley on a golf course, he should not hit the ball into them. It shows a case where the problem is put out, proving that it is due to psychological effects.

[0007] That is, the psychological action according to the degree of consciousness of the player's visual perception of the event causes the player to launch the ball in his hitting action (swing) regardless of the superficial intention of the player. It was a factor that had a major influence. Of course, apart from the results,
It had a great influence on ball control that surpassed even advanced players.

[0008] In order to facilitate the launch of the ball at the sweet spot, according to the literature, as shown in the front view of the club head in FIG. 1 and the cross-sectional view in FIG. The projection, which should not be on the face, was intentionally provided at the center of the sweet spot.

[0009] This means that there is something that cannot be ignored on the face surface, and the resulting psychological action creates a swing that hits the ball at the time of hitting the ball, regardless of the superficial intention, Since the projection is located at the center of the sweet spot, as a result, it is easy to launch the ball at or near the center of the sweet spot.

[0010]

However, in the clubs shown in FIG. 1 (FIG. 2) in the literature, psychological effects may be unexpectedly emphasized. (Sweet spot) was largely removed, and the ball was launched, causing a psychological effect that seemed impossible to catch the ball at the sweet spot.

[0011] As described in that document, this is not only a psychological effect on the protrusion on the face surface,
Due to the fact that the physical effect on the ball (possibility of pushing the ball in a different direction) is left at all, if this is overly conscious, avoid bumps as well. The consciousness of the swing was superior, and the disturbance of the swing was caused by it.

[0012] This is inevitable as long as the physical action on the ball is slight, but a projection is formed on the face surface and the psychological action thereby is applied. As a result, the effect obtained was unstable.

However, if the harmful effects of the projections are avoided and only the visibility is settled and the arrangement of flat marks or simple depressions is stopped, there is no adverse effect due to excessive consciousness, but an effective effect by the psychological action can be obtained. It cannot be done.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to solve the above-mentioned problems and to provide a golf club capable of stably launching a ball at a sweet spot by a psychological action. .

[0015]

In order to solve the above-mentioned problems, according to the present invention, a depression is formed at the center of a sweet spot, and a projection is formed inside the depression. It is configured not to be formed on the top.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION
A recess for forming a protrusion of about mm is provided, and a protrusion is formed therein, so that the protrusion is not formed on the club face surface.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows an embodiment in an iron club.
Although the front of the club head is shown, a depression 3 is provided in the center of the sweet spot 2 indicated by a broken line in the face 1 (score line is omitted in the figure), and a projection 4 is provided inside the depression. Is formed. FIG. 4 shows a cross section of the side surface at the center of the sweet spot. The projection 4 is formed inside the depression 3 and not formed on the face surface.

As a result, the physical action on the ball can be neglected, so that excessive consciousness is not aroused, and no adverse effect is caused thereby. Of course, in the case of a flat face, clear irregularities that are clearly different from the surroundings are formed at the center of the sweet spot, so it is different from a flat mark or a simple depression. As a so-called annoying thing, the center of the sweet spot can be sufficiently conscious.

Here, it acts as a kind of concentration, which significantly increases the probability of launching the ball at the sweet spot regardless of the skill of the player, and has no adverse effect due to excessive consciousness. It will be stable.

As described above, as long as the configuration of the club as a tool for hitting a ball is not limited to the physical configuration but is used by a person, incorporating the psychological effect thereof can obtain the required result. It is an extremely effective means for

In the example shown in the figure, the outer periphery of the depression 3 provided at the center of the sweet spot is shown as circular but may be square, and the projection 4 is shown as being integrally formed. You may. In the example shown in the figure, an iron club is shown, but any material such as wood or putter may be used.

[0022]

As described above, in the present invention,
By forming clear irregularities in the center of the sweet spot, the concentration of the player is made to act, the probability of the ball being hit at the sweet spot is remarkably increased, and there is no adverse effect due to excessive consciousness Therefore, the effect is stably provided.
