JPH0284971A - Tennis ball with identification mark - Google Patents

Abstract

PURPOSE:To use tennis balls, which are wholly yellow samely as an officially recognized ball, without worrying the distinction of an owner by adding an identification mark, which is prepared by arranging two rectangles or circles in different color in an adjacent relation, on the surface of the tennis ball. CONSTITUTION:The tennis ball is given identification marks B and C which are prepared by using two rectangles 1 and 2 in the different color or two circles 3 and 4 in the different color. Thus, the ball can be identified by changing only a point mark on a surface without changing the basic color (one color of yellow, for example) of the tennis ball. Since the two graphics in the different color are coupled for the identification mark, the various types of the identification marks can be made according to the coupling of the color without changing the basic shape of the mark.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a tennis ball used in both hard and soft tennis.

[Conventional technology]

In the past, tennis balls used to be all white, but in recent years this has been reconsidered to make them easier to see, and the color of tennis balls used in official matches (so-called official balls) is now entirely yellow. Colors are now used. The yellow surface of a tennis ball, especially a certified ball,
It usually does not bear any markings other than the manufacturer's trademark or similar markings.

[Problems to be solved by the invention]

It goes without saying that it is advantageous for players to use the same yellow ball as the official ball during practice. When practicing tennis, in order to practice efficiently, -
Often uses many balls. In general practice at the amateur level, multiple players often practice using their own balls. If there are yellow balls from the same manufacturer that are owned by different owners, it will be difficult to identify the balls and it will be difficult to tell which ball belongs to whom. Furthermore, when there are multiple courts within the same net fence and each court is used by a different party, the balls of each party intersect with each other within the net fence, making it difficult to determine which one is the best. I can't tell which party the ball belongs to. In order to avoid the above situation, each manufacturer takes measures such as assigning numbers, changing the colors of the balls themselves (limited to practice balls), or using two-tone colors at the seams. ing. However, even though it is practice, in order to get better results, it is necessary to use the same yellow ball as the official ball.
It is better to use colored balls. Additionally, owners sometimes mark the surface of the ball using various types of ink to clarify the attributes of the ball to an individual or a group, but the results are not very pretty. It's hard to say that it's smart, even in flattering terms.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the tennis ball with an identification mark of the present invention has the following configuration. In the tennis ball with an identification mark shown in claim 1, the surface of the tennis ball A has two rectangles (
1X2) is attached with an identification mark B created adjacent to it. Furthermore, the tennis ball with the identification mark set forth in claim 2 is created using two circles (3) and (4) in different colors instead of the two rectangles (1) and (2) in different colors. It has an identification mark C.

[Effect]

Although the present invention has a simple structure as described above, its operation is as follows. The tennis ball can be identified by changing only the point marks on its surface without changing its basic color (for example, yellow). Furthermore, since the identification mark is a combination of two figures of different colors, many different types of identification marks can be created by combining the colors without changing the basic shape of the mark.

【effect】

As a result of the above-described operation of the tennis ball with identification marks according to the present invention, the following effects are produced. When multiple players or parties bring together their own tennis balls for practice, even if they are from the same manufacturer, as long as they use balls with different identification marks, the ownership Tennis balls, which have the same general yellow color as the official ball, can be used without worrying about distinguishing between them. Since the identification mark is a combination of two colors, countless combinations are possible, making it possible to identify many types. Since the identification mark is not just numbers or symbols, but a combination of shapes and colors, the design benefits cannot be overlooked. In addition, as an embodiment of the present invention, it is also possible to replace the two rectangles or circles of different colors, which are the constituent elements of the identification mark, with two various polygons, star shapes, letters, symbols, etc. of different colors. It will be done.

[Brief explanation of the drawing]

Figures 1 and 2 are perspective views of an example of a tennis ball with identification marks according to the present invention (1), (2) are colored rectangular marks for creating identification mark B (3), and (4) are identification marks. The colored circular mark A for creating C is a normal tennis ball. B and C are identification marks as an example of the present invention.
