Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION This invention relates to an indoor stadium floor with athletic court line identification lights and power control box in an indoor stadium.

``Prior Art'' Until now, on the floors of indoor stadiums, court lines for various athletic events were displayed in different colors on the same floor. For example, athletic court lines on the same floor were identified by colored paint, such as white lines for volleyball courts, yellow lines for basketball courts, and blue lines for badminton courts. However, no matter how easy it is to identify court lines that are displayed in different colors, if there are many lines that intersect on the same floor, the human eye will only see a complicated geometric color pattern, so umpires will When there is a fierce competition for points, players have to be extra careful than necessary to ensure that there are no mistakes in making critical decisions on the court line, and to keep the game fair. Also, when the spectators' cheering team was at a disadvantage, they emotionally lost faith in the game and felt a great sense of dissatisfaction.

In order to eliminate such drawbacks, this invention provides an athletic competition in which referees, players, and spectators can clearly identify each other even if the court lines on the same floor of an indoor stadium intersect, and can enjoy healthy sports play to the fullest. Provide indoor stadium floors with court line identification lights and power control boxes.

``Means for solving problems'' Explain the floor surface of indoor stadiums with structure. The entire floor plane is shown in Figure 2, where several types of athletic court lines intersect. The structure will be explained with reference to FIG.

B. A floor recess 2 with the width of the athletic court line shall be provided on the floor 1 of the indoor stadium.

(b) The lamps 3 are housed in the floor recesses 2 at equal intervals.

C. Cover the floor recess 2 with an opaque plastic plate 4 and fix it 1
The same surface as floor surface 1.

D. The power control box 5 includes a changeover switch 6 for displaying the athletic court line on the floor 1 and a dimmer 7 for adjusting the illuminance. Then, the lamp 3 and the power control box 5 are connected with the power line 8.

"Operation" In order to form and display an athletic court line on the floor surface 1 using the structure shown in FIG.
For example, when switching to the volleyball court line as shown in FIG. 3 and turning on the power, the lamps 3 in the floor recesses 2 light up at equal intervals, forming and displaying the volleyball court line. Then, the light fixture 3 is controlled by the dimmer 7 built into the power control box 5.
The brightness of the formed and displayed volleyball court line is adjusted.

"Example" An example will be described. FIG. 2 is a plan view of the entire floor surface before formation and display. FIG. 3 shows a first embodiment of the invention. In the first embodiment, volleyball court lines are formed and displayed on the floor 1 of an indoor stadium. FIG. 4 shows the basketball court lines of the second embodiment, and FIG. 5 shows the badminton court lines of the third embodiment on the floor 1 of an indoor stadium.

"Effect of the invention" This invention has the following effects.

B. Conventionally, athletic court lines were displayed in different colors using white, yellow, and blue paint on the same floor, so the intersecting lines of the court lines were complicated by the colors, which caused visual nerve fatigue for referees and players. , both the audience and the audience are relieved.

(b) Only the athletic court line, which is set by operating the changeover switch 5 built into the power control box 5, is displayed on the floor 1 of the indoor stadium by lighting, so that it can be clearly identified.

C. The brightness of the athletic court line on the floor 1, which is lit by operating the dimmer 7 built into the power control box 5, is adjusted to match the indoor illuminance so that the eyes of players and referees are not dazzled. Dimmable and adjustable.

D. The above effects combine to make athletic court lines clearly distinguishable, exciting even the most dangerous plays near the court lines, and allowing players, referees, and spectators to enjoy sports play to their heart's content as a healthy and effective use of leisure time.

It is possible to display the formation of court lines in any athletic event that is possible in an indoor stadium.

The power control box 5 has a built-in changeover switch 6 and a dimmer 7, but it can also be used as an automatic control box that meets the above requirements.It senses indoor illuminance by linking with a light sensor and a computer, and adjusts accordingly. This indoor stadium floor is equipped with athletic court line identification lights and a power control box that can automatically display and dim the athletic court lines so as not to dazzle during a game. This invention produces such effects.

Although a preferred embodiment has been described above, this embodiment is not limited to the present invention, and various improvements and changes can be made without departing from the spirit of the invention.
