Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an emergency exit (evacuation exit) for people when a fire occurs.
It is used in the technical field of fire evacuation guidance to guide people to safety, and specifically, it is used in the technical field of fire evacuation guidance, which can quickly and safely guide people who were present at the location of the fire to an emergency exit. Regarding equipment.

(Prior Art) Conventional fire evacuation guide lights have a doll pattern and an arrow (see attached drawing) displayed on the surface to indicate the direction of the emergency exit, and when a power outage occurs due to a fire or other unexpected accident, People who were present quickly and.

The passageway is clearly illuminated so that evacuations can be safely guided toward the emergency exits. Additionally, there are devices that have been devised to make evacuation guidance safer by adding sound generators, warning lights (patrol lights), etc. to the above guide lights to indicate emergency exits and evacuation routes with sound and light. do.

[Problem to be solved by the invention]

However, in the conventional guide lights described above, the design and arrow always face the emergency exit in a certain direction, making it impossible to safely guide people to evacuate in the event of a fire.

In other words, in the event of a fire, it is necessary to determine the safe direction and evacuation direction within an extremely short period of time, such as 1 to 2 seconds. People evacuate believing that they are in a safe direction, but if the source of the fire is in the direction the guide lights are guiding them to, they will lead people in the opposite direction to the source of the fire. , there were problems that were extremely dangerous and could lead to major accidents.

In particular, underground malls and passageways and corridors inside large hotels are said to be labyrinths, and the exit direction is unclear and often gets lost, but you are surrounded by smoke generated by a fire, and the surroundings are surrounded by power outages. In the event of an abnormality that cannot be confirmed visually, the evacuation direction cannot be determined at all. Therefore, if the only reliable guide light is pointing in the direction of the fire source, a large number of people will use this guide light. It was inevitable that people would believe the fire and flee in the direction of the fire, which would have caused an even bigger accident.

Also, even if you are lucky enough to reach emergency 0 safely, if you use the emergency stairs to evacuate, just seeing the guide lights that indicate the location of the conventional emergency stairs will make you wonder if it is okay to escape to the upper floor. On the other hand, because it is not possible to judge whether it is best to escape to the lower floor, there are cases where people erroneously evacuate towards the floor of the fire and cause an accident. Even if lights and warning lights are added, people present at the fire will not be able to quickly evacuate to a safe direction during a power outage, and the presence of guide lights may actually make the accident worse. Ta.

Therefore, the technical problem of the present invention is to display the arrow of the guide light in the opposite direction to the fire source when a fire occurs.
The goal is to reliably guide people to evacuate in a safe direction away from the source of the fire.

[Means to solve the problem]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) At least two types of arrow guidance displays pointing in opposite directions are configured on the display section of the guide light so that the display can be switched freely by a switching device.

(2) When a fire occurs, the above switching device detects the fire detector that is in operation from among the multiple fire detectors installed in each room or location, and also selects one of the above arrow guidance displays. A control device is connected that selects an arrow guidance display pointing in a direction away from the detected fire detector, and controls and operates the switching device to display the selected arrow guidance display on the display section of the guide light. to do.

(3) In addition to the two types of arrow guidance displays, a warning display that warns of the danger of fire in text can be freely switched on the display section of the guide light, and the control device can switch between the two types of arrow guidance displays. It shall be configured so that the above warning display is displayed on the display section of the guide light near the fire outbreak.

(4) The guide light is provided with a warning light that is activated by the control device to notify the danger of fire with light, and a sound generator that generates a sound for guidance.

However, the at least two types of arrow guidance displays and warning displays that are switched and displayed on the guide light display section are those that use multiple panel boards each displaying a pattern, an arrow, and a warning letter on the surface. It means a display device, or a display device such as an LED display device that can switch between these symbols, arrows, and warning letters. Furthermore, at least two types of arrow guidance displays pointing in opposite directions mean arrows pointing in different left and right directions or in the direction of the upper tool.

[Effect]

The above means works as follows.

(1) The elements described in (1) above do not fix the arrow guide display displayed on the display section of the guide light only in one direction, but allow it to be switched to the opposite direction from left to right, or to the direction of the upper tool.

■The element mentioned in (2) above allows the arrow direction of the display unit, which is configured to be freely switchable from side to side or up and down, to always be displayed in the direction away from the fire source, that is, in the opposite direction. To enable people present at a fire to evacuate in a safe direction away from the source of the fire even during a power outage.

■The elements mentioned in (3) above are for example shown on the display of a guide light near the source of a fire to warn of the danger of a fire.
By displaying warning letters such as "Fire Outbreak/Danger," people can see that a fire is occurring nearby and can quickly evacuate away from the source of the fire. 6 ■The elements mentioned in (4) above include, in addition to evacuation guidance using arrow displays and warning displays, for example, the light of rotating or flashing warning lights and the message "Please evacuate by following the arrows on the guide lights." Evacuation guidance can be provided by voice, making it possible to provide safer and more reliable guidance.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
