Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club spray for spraying fine powder onto the face of a golf club face such as a driver or iron, and leaving a mark (location) hit by a ball by a layer formed by the fine powder. It is.

In order to hit a good shot in golf, it is important to capture the ball at a portion called a sweet spot in the face (ball striking surface) of the golf club. However, it is difficult for amateurs to stably catch a ball with a sweet spot. For this reason, there is a proposal of a golf club that can adjust the trajectory of the ball even if the sweet spot is removed. However, there is no doubt that the basics are to catch the ball at the sweet spot.
5-48971 For this reason, it is often the case that the player adjusts the form so that the ball can be caught at the sweet spot.

  In this adjustment, it is important to know exactly where the ball is hitting the face, but since the face is made of a hard material such as metal, there is almost no trace of the ball hitting. where to hit because that rely on sensitive was the situation.

  There is also a method to check the hit point by sticking a sheet, but after checking the hit point, it takes time to peel off the sheet, or there are problems such as peeling off the sheet while using it, it is not comfortable to use It was. In addition, since it was changed many times in one practice, there was a problem that the hand was sticky with the adhesive applied to the back of the sheet, and it was difficult to clean the peeled sheet.

  Golf has a great mental impact, so even if you adjust the form without knowing exactly where the ball is hitting, the player is not confident, and as a result, the adjustment of the form will not proceed smoothly. There were many.

Means to solve the problem

  In order to solve this problem, in the golf club spray of the present invention, a liquid obtained by dissolving a fine powder such as calcium carbonate in an alcohol solvent is golfed by a sprayer using liquefied petroleum gas (LPG) or manually compressed air. Spray on the club face. By doing so, a fine powder layer is formed on the face surface, and a trace of the ball remains due to peeling or compression of the fine powder layer where the ball hits.

In addition, since the fine powder is basically attached, the fine powder can be easily removed by wiping with a cloth.
For this reason, after hitting several times to about 10 times, when it becomes impossible to discriminate individual ball marks, it is easy to spray the fine powder again. In some cases, it may be sprayed on the layer having the traces.

Although the fine powder is moistened by the solvent at the moment of spraying, it is dried in a short time because the solvent is volatile. Moreover, since the traces of the ball remain even if it is not completely dried, there is no practical problem. For this reason, it is not necessary to be particularly aware of the drying time.
In addition, the fine powder layer only needs to leave a trace that can be used to determine where the ball has hit, so that it is not necessary to strictly control the thickness and uniformity.

The invention's effect

  When the golf club spray of the present invention is used, the following advantages can be obtained when the swing is adjusted.

1. Since the ball mark remains on the face, the player can adjust the swing while checking the hit point for each hit.
2. Since the swing can be adjusted while checking the ball mark, a spiritual sense of security is obtained, which leads to the player's confidence.
3. Since it is a layer sprayed with fine powder such as calcium carbonate, it can be easily wiped off with a cloth, and the wiping does not take time. Moreover, it does not matter if it is sprayed repeatedly without wiping.
4). Since only a thin fine powder layer is formed on the face, the weight of the club and the feeling of hitting are not affected.
5). Since it is not necessary to strictly control the thickness and uniformity of the fine powder layer, the golf club spray of the present invention can be supplied at a low price.
6). The ball hits the face during the swing near the ground. For this reason, even if the fine powder is scattered, the possibility that a human will inhale the fine powder is low and the human body is less affected.

  A first embodiment of the present invention will be described with reference to FIGS.

In the present embodiment, a liquid obtained by dissolving fine powder in an alcohol solvent is sprayed on the surface of the face 1 of the golf club with a spraying device, and a thin layer 2 of fine powder is formed on the entire surface of the face 1.
When the fine powder layer 2 is formed on the face 1 in this way, the fine powder is peeled off or compressed when the ball is hit with the face 1, thereby leaving a trace 3 of the ball on the fine powder layer 2. By leaving the trace 3, the player can adjust the swing while confirming where the ball hits the face 1 every time. In addition, it becomes possible to grasp the tendency (傾向) of the person's swing by attaching traces of a plurality of balls.

As this fine powder, for example, a fine powder of calcium carbonate (limestone) may be used. Further, an appropriate amount of a surfactant for weakening the surface tension and a thickening agent such as silicic acid, silica gel, or hydroxyethyl cellulose for strengthening / adjusting the adsorptive power may be added so as to spread over the entire surface of the face 1.
As the alcohol solvent, glycerin, ethylene glycol, diethylene glycol or the like can be used.
The spray for spraying this liquid is basically a mixture of a fine powder and a solvent, a type (FIG. 2) composed of a container 5 and a spraying device 6 separately storing LPG, or a fine powder and a solvent. The type (FIG. 3) etc. which consist of the container 5a which put the liquid mixture, and the spraying instrument 6a which pulls the trigger 7 manually and compresses air can be used.

  Here, the spraying device is a spraying device that is generally widely used for mixing and spraying the liquid and gas sucked up using the principle of spraying. The materials necessary for the present invention are also widely used and there is no special material. For this reason, no further details are given.

Further, when it becomes difficult to discern individual marks due to a plurality of ball marks, the fine powder can be easily removed by wiping with a towel or the like. Or you may spray it repeatedly. (May be overcoated)
The fine powder and the solvent may be placed in separate containers in the spray and mixed when sprayed.

  Thus, if the fine powder layer is formed on the face by the golf club spray of the present invention, the trace of the ball hit by a simple operation can be left on the face, which is very useful for improving the swing. In addition, the improvement of the form after confirming the trace of the ball gives the player a sense of security and confidence.

  As described in the above embodiment, if the golf club spray of the present invention is used, it is possible to leave a trace of the hit ball on the face surface with a simple operation, so practice for hitting the ball to the sweet spot It is very useful for adjusting the swing.

If the golf club spray of the present invention is used, it is possible to leave a trace of the ball hit on the face of the golf club with a simple operation as described above. For this reason, it is highly useful as a supplement to improve golf.
In addition to golf, the spray of the present invention is also effective for sports that catch a ball at a sweet spot, such as a tennis racket or a baseball bat.
