== First Embodiment ==
First, a first embodiment that is one of the embodiments of the present invention will be described. Drawing 1 is a figure showing fire door 1 in a first embodiment. The fire door 1 is normally stored in a door pocket or the like provided on the wall surface 2 of the passage. In an emergency such as the occurrence of a fire, the passage is closed automatically by a signal from a fire alarm or manually by a fire prevention person or the like. By closing the fire door 1 in this way, it is possible to prevent the expansion of the fire range and the outflow of smoke.

  On the other hand, some evacuees evacuate through a passage where the fire door 1 is closed. Therefore, the fire door 1 is provided with an opening 3 and an evacuation door 4 for closing the opening 3 as shown in FIG. The evacuees can evacuate through the opening 3 by turning the knob 5 to open the evacuation door 4.

  However, when smoke from the fire fills the passage, the refugee may not be able to find where the evacuation door 4 is, and may be delayed. Even if the evacuation door 4 can be found, the evacuation door 4 may be crazed without noticing the step between the evacuation door 4 and the floor surface 7 of the passage. When evacuating, a large number of evacuees run into the evacuation door 4 and one evacuee hits and falls, so that the subsequent evacuees also fall in an overlapping manner. For this reason, many evacuees who are late to escape occur, and there is a risk that secondary disasters may occur due to falls or underlays of other evacuees.

  Therefore, in the present embodiment, a plurality of light emitting devices 6 are disposed on the outer periphery of the opening 3 along the outer edge of the opening 3. The light emitting device 6 emits light by electrical energy, such as a light emitting diode, an incandescent lamp, a halogen lamp, or a xenon lamp. The light emitting device 6 may be covered with a transparent heat resistant glass. By being covered with the heat resistant glass, it is possible to prevent the light emitting device 6 from being damaged by the heat at the time of fire.

  A signal receiving unit 8, a power supply unit 9, and a control device 10 are installed on the wall surface 2. The signal receiving unit 8 is a device that receives an emergency signal transmitted from the fire alarm 11 or the like by wire or wirelessly. The power feeding unit 9 is a device that supplies power to the light emitting device 6. The power feeding unit 9 supplies the power acquired from the external power source 12 to the light emitting device 6 in response to the emergency signal received from the fire alarm 11 by the signal receiving unit 8. The control device 10 is a device that controls lighting, blinking, or extinguishing of the light emitting device 6, and is, for example, a blinking circuit. The external power supply 12 is a power supply device that supplies power to emergency lighting or the like installed in a building in the event of an emergency such as a fire. In addition, although the signal receiving part 8, the electric power feeding part 9, and the control apparatus 10 shall be installed in the wall surface 2, it is good also as being provided in the fire door 1. FIG.

  Thus, when the fire alarm 11 detects a fire and transmits an emergency signal, the light emitting device 6 disposed around the emergency door 4 of the fire door 1 is turned on. Further, the light emitting device 6 can be blinked by the control device 10. When the light emitting device 6 is turned on, the evacuee can easily find the evacuation door 4 even when the smoke from the fire is filled in the passage. Moreover, since the light-emitting device 6 is also arrange | positioned also at the upper end of the level | step difference of the opening part 3 and the floor surface 7, an evacuee notices a level | step difference and can evacuate without hesitating. Further, by blinking the light emitting device 6, it is possible to attract the attention of the evacuee who is upset by the fire and to make the refugee recognize the position of the evacuation door 4. Furthermore, since the power consumption is smaller when blinking than when it is lit, the consumption of the external power supply 12 can be reduced, and the light emitting device 6 can be kept blinking for a longer time. In this way, by turning on or blinking the light emitting device 4 in a situation where the smoke is full, the evacuee can easily recognize the position of the evacuation door 4. Therefore, it is possible to prevent the occurrence of a secondary disaster due to the escape delay or whispering of the evacuees.

  In addition, by using a light emitting diode as the light emitting device 6, power consumption can be reduced as compared with an incandescent bulb or the like. In addition, the light emitting diode has excellent impact resistance, and can prevent the light emitting device 6 from being damaged by the impact when the heavy fire door 1 is closed. And by using a red light emitting diode as a light emitting diode, the position of the evacuation door 4 can be recognized from a farther place. This is because red has the longest wavelength in visible light and is less attenuated by smoke or the like. Alternatively, an automatic flashing type light emitting diode may be used as the light emitting device 6 without using the control device 10. The automatic flashing type light emitting diode is a light emitting diode with a flashing circuit built therein, and flashes at a predetermined interval when power is supplied.

== Second Embodiment ==
Next, a second embodiment that is one of the embodiments of the present invention will be described. Drawing 3 is a figure showing fire door 1 in a second embodiment. The opening 3, the escape door 4, and the light emitting device 6 are the same as those in the first embodiment.

  The fire door 1 includes a signal receiving unit 8, a power feeding unit 9, and a battery 13. The signal receiving unit 8 and the power feeding unit 9 are the same as those in the first embodiment. The battery 13 is, for example, a storage battery or a solar battery having a power storage function.

  In such a fire door 1, the power receiving unit 9 supplies power stored in the battery 13 to the light emitting device 6 in accordance with an emergency signal received by the signal receiving unit 8 from the fire alarm 11 or the like, thereby emitting light. The device 6 can be turned on.

  Thereby, similarly to the case of 1st embodiment, even if it is a case where the smoke by a fire has filled the passage, the evacuee can discover the evacuation door 4 easily. In addition, since the light emitting device 6 is also disposed at the upper end of the step between the opening 3 and the floor surface 7, the refugee can notice the step and can evacuate without hesitation.

  Further, by using an automatic flashing light emitting diode as the light emitting device 6, the light emitting device 6 can be flashed. Moreover, the fire door 1 is good also as providing the control apparatus 10 demonstrated in 1st embodiment.

  When the battery 13 is a storage battery, the battery 13 is connected to an outlet of a general AC power source provided on the wall surface 2 or the like and stores electric power. By using a storage battery that obtains power from a general AC power source as the battery 13, special wiring work or drilling work for connecting to an emergency power source or the like is not required when the fire door 1 is installed.

  Further, when the battery 13 is a solar cell having a power storage function, the battery 13 stores power by receiving light emitted from a fluorescent lamp or the like installed in the building. In this case, the battery 13 is disposed at a position where light from a fluorescent lamp or the like can be received even when the fire door 1 is stored in the wall surface 2 or the like. Furthermore, if the signal receiving unit 8 receives an emergency signal from the fire alarm 11 or the like wirelessly, no wiring with an external power source or a fire alarm is required when installing the fire door 1. . Therefore, even if the wall surface 2 is not provided with an outlet, the fire door 1 can be installed without performing wiring work. Therefore, the process when installing the fire door 1 in the building is simplified, and the construction period can be shortened and the construction cost can be reduced.

  Further, by covering the light emitting device 6, the signal receiving unit 8, the power feeding unit 9, and the battery 13 with heat-resistant glass, it is possible to prevent damage due to heat of fire. Since the heat-resistant glass transmits light, a solar cell having a power storage function can be used as the battery 13.

  Although the embodiment of the present invention has been described above, the above description of the embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. It goes without saying that the present invention can be changed and improved without departing from the gist thereof, and that the present invention includes equivalents thereof.
