Description

Line indication control system of indoor stadium {Line indication control system of gymnasium}

The present invention relates to a line display control device of an indoor sports stadium, and more specifically, it is possible to selectively display only the necessary game lines according to the sporting events in an indoor stadium in which a plurality of game lines are formed on the floor to perform various sporting events. The present invention relates to a line display control device that does not cause confusion for the players during the game, and that the game organizer can ensure the accuracy of the judgment and help the game.

In general, the indoor stadium floor has a complicated line to play various sports such as volleyball, basketball, handball, etc., in order to allow various sports to be played in one indoor stadium. It is true that it is inevitable.

Players playing in such a traditional indoor stadium are often confused by the lines formed regardless of the ongoing game, and they also nourish the judges' judgments, and often act as obstacles in running a healthy sports game due to the coming judgment. Has come.

The present invention has been devised to solve the above problems, the purpose of the present invention is to selectively play only the required game line according to the game in the indoor stadium where a number of game lines formed on the floor to perform a variety of sport events It is to provide a line display control device of an indoor stadium that can be displayed.

The present invention for achieving the above object, the rectifier 20 receives the external commercial AC power supply 10 and converts it to a predetermined DC voltage, and receives a key signal of the event selection switch 30 to select a specific game line Switching unit 40 is switched to display the heat generating member, the heat generating member that the heat generated by the current supplied selectively by the switching operation of the switching unit 40, the DC voltage converted by the rectifier 20 ( 50) and a color converting material layer 60 for converting colors by receiving heat generated from the heat generating member, and a white formed between the color converting material layer and the heat generating member to express a line of a specific sporting event. It is made of a sheet layer 70 and the adhesive sheet layer 80 to enable adhesion with the stadium bottom surface.

Hereinafter, the line display control device of the indoor stadium of the present disclosure will be described with reference to the accompanying drawings.

1 is a schematic control block diagram showing a line display control device of an indoor stadium of the present invention, FIG. 2 is a partial installation cross-sectional view of the line display control device of the present invention, and FIG. It is an illustration.

As shown in the figure, a rectifier 20 for receiving the external commercial AC power supply 10 and converting it to a predetermined DC voltage is provided, and receives a key signal of the event selector switch 30 to select a specific game line. The switching part 40 which switches operation so that it expresses is formed.

In addition, a heat generating / transmitting member 50 is provided in which heat is generated by a current selectively supplied by the switching operation of the switching unit 40 to the DC voltage converted by the rectifier 20.

Here, the heat generating / transmitting member 50 is formed on the lower side of the white sheet layer 70 and is heated by resistance by receiving a DC voltage supplied from the outside and is heated to an appropriate temperature or receives heat from an external heat source. It is configured to heat layer 60.

In addition, as shown in FIG. 2, a fine-thick color conversion material layer 60 is formed on the upper side of the white sheet layer representing the race line, the color of which changes with temperature, and the surface protective film layer 90 is formed thereon. Is formed, the color conversion material is converted to a transparent color when raised to a predetermined temperature is configured so that the white sheet layer 70 formed on the lower side can be displayed on the floor of the stadium.

In addition, the adhesive sheet layer 80 is provided to fix / support the plurality of layers on the floor of the stadium.

Here, for example, Zion ink may be used as a material of the color converting material layer, which is a material whose color is changed according to the contact temperature.

In other words, the color converting material uses a material that is changed to a transparent color when heated to a predetermined temperature by the heat generating / transmitting member 50 so that a white sheet layer formed on the bottom thereof can be displayed on the floor of the stadium.

Referring to the operation of the present invention configured as described above are as follows.

When playing an indoor game, if a sports event is determined, when the stadium manager operates the sports event selection switch 30, the DC voltage (current) rectified through the rectifier generates heat formed under the white sheet layer 70 of the specific game. It is supplied to the / transmitting member 50 and is heated by resistance or receives heat from an external heat source, the temperature is raised to an appropriate temperature, and thus is transferred to the color conversion material layer 60 formed thereon.

The color conversion material layer 60 is the first color disappears by the supplied heat to change to a transparent color and a white sheet layer (line) representing the stadium of a specific item is to be displayed on the floor of the stadium.

As described above, according to the present invention, in the indoor stadium where a plurality of game lines are formed on the floor to perform various game items, only the necessary game lines can be selectively displayed according to the game items, causing players to have confusion during the game. It does not cause any damage to the match and can also help to observe the match.
