Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hitting point display tool for a golf ball, which indicates where on the club face the ball is hit when the golf ball is hit by the club. Yes, and more specifically, the structure of the display method.

[Prior Art] It is an eternal task for golfers to fly the ball farther and more accurately. And the most important and fundamental thing for this is to hit the ball at the true center of the club face, the so-called sweet spot. Therefore, from the history of golf, it is considered natural that a method of knowing whether or not a ball hits a sweet spot has long been known. However, mysteriously, little was known about the visual method.

The reason for this may be that he believed that the player himself had hit and was not willing to check. However, the biggest cause is considered to be the rules of golf competition. That is, this regulation prohibits sticking anything on the club face. For example, he says he should not paint with chalk. It is probable that the player was only taboo when he hit the ball, because he knew the position of the ball by turf sandwiched between it and the club face.

However, recently, a method of breaking this taboo and sticking something on the club face has appeared as a product. However, according to the instruction manual of this product, it is said that it is not a golf practice product, so it cannot be said that the taboo was breached accurately. Rather, from the idea that the golf course is a place to enjoy playing, not a place to practice, it can be said to be fit for purpose.

On the other hand, clubs with wide sweet spots have recently been commercialized. This facilitates hitting the ball at the sweet spot, but at the same time illustrates the importance or difficulty of this.

[Problems to be Solved by the Invention] Since the present invention is a system for sticking things on the club face, it is limited to practice golf, but in the case of such a limitation, there are necessary conditions for that purpose.

The first is that it does not adversely affect the ball. For example, it should not be scratched or colored.
The second is not to affect the performance of the club. This section is related to the reason for prohibiting it in the Rules of Golf, and it is difficult to eliminate its effects, so the goal is to minimize it. For example, to minimize the effect of the weight. One pro golfer can tell by sticking a 1-yen aluminum coin to the club. Second, it is easy and easy to use. When hitting a ball in the practice field, the number of balls is generally about 50 per basket, and is generally several baskets.
The number of "dotting sheet" should be considerable. Therefore, it is easy to attach / detach to / from the club. And, above all, it is important that the cost of the ball is cheap.

The prior art described in the prior art is an application of carbon-free paper technology, in which a sheet-like material is attached to the club face, and when hitting a ball, the hitting point turns red or the like. However, the degree of discoloration is remarkably poor at the upper portions of the left and right ends of the sheet to which the adhesive is attached, which is used for attaching to the club. This indicates that the seat surface cannot be used 100% effectively. This prior art has some doubts about coloring the ball, but the main problem is that the cost of the ball is low, which is the problem to be solved by the present invention.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, an aluminum foil lined with a paper-like material is provided with fine mesh-like irregularities to make its surface matt, Next, a feature is that a sheet having a structure in which a double-sided tape is attached to the surface of the backing paper is used. Further, the size of the seat covers a large part or a small part of the club face depending on the technical level of the player.

[Operation] When the sheet having the above structure is attached to the club face and the ball is hit with this, the hit portion of the ball on the aluminum foil is extended, and as a result, the matte state disappears. Therefore, the hitting point of the ball can be easily identified by the difference in gloss.

Also, the adhesive layer of the double-sided tape has almost no effect on the appearance of the dots on the aluminum foil, so even if the sheet is made small,
I can fulfill my purpose.

[Examples] Examples will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a sheet-shaped product of the present invention, in which an aluminum foil 1 is lined with a paper-like material 2, and the aluminum foil surface has concave portions 1a and convex portions 1b. , These irregularities form a mesh pattern on the aluminum foil surface. The adhesives for both are not shown. By the way, the sheet-like material having such a structure is very commonly used in daily life, and particularly, it is often used for packaging. In this example, those used for tobacco and chewing gum were used. A double-sided tape 3 is attached to the surface of the paper-like material 2 of this sheet. When using, double-sided tape quality 3b
Get rid of. FIG. 2 is a sectional view of the product of the present invention in use, which is attached to the face 4a of the club 4 by the action of the adhesive layer 3a of the double-sided tape. FIG. 3 is an explanatory view of the hitting point display of the ball, and the aluminum foil 1 is visible on the club face 4a.
The part A shown by hitting a large number of dots shows the original matte part without hitting the ball, and the part B not hitting the dot shows a part glossy when hit by the ball. C in B
Indicates the groove portion on the club face. Although not shown in B, a dimple mark on the ball can also be seen. The wrapping paper used for cigarettes had a square mesh consisting of about 25 lines per cm, but in this case A and B
The difference in gloss was clear. On the other hand, the one for chewing gum had a fine mesh and was barely visible to the naked eye, but the gloss difference between A and B in this case was small. A ball was applied to a composite material of a meshed aluminum foil and a plastic film for drug packaging, but in this example, almost no deformation was observed, which was unsuitable for the purpose of the present invention.

In FIG. 3, the aluminum foil 1 covers almost the entire surface of the club face 4a, but the shape of the product sheet of the present invention is not limited to that shown here. When a part of the sheet sticks out from the face, that part may be bent and attached to another part of the club. Also, if you are a good person,
It may cover, for example, about half of the club face centered on a sweet spot (not shown). Especially in such a case, the device sheet may be in the form of a stamp sheet instead of being cut in a 1: 1 correspondence with the club face.
Furthermore, the double-sided tape, or more precisely the adhesive layer 3a, need not be adhered to the entire surface of the club face 4a, and may be only the upper and lower ends or the left and right ends of the club face. The point is that the seat can be easily attached to and detached from the club.

[Effects of the Invention] Since the present invention is configured as described above, it is easy and easy to practice this against hitting the ball with the center of the club face, which is the most important and basic in golf. A means of doing so can be provided.
