Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key storage device suitable for storing a key for a lock at an entrance of a school, a park, or the like, which is designated as an evacuation site at the time of disaster and whose entrance is locked and controlled.

2. Description of the Related Art Locking management is often performed in schools and parks designated as evacuation sites during disasters. Therefore, if an emergency evacuation is necessary due to the occurrence of a disaster, do not enter the evacuation area until a manager with a key comes. In addition, some parks are always closed not only at night but also at doorways, so that evacuation in an emergency takes time. Further, when it is necessary to evacuate at night, it is assumed that the key storage location may be lost due to a power failure.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is easy to find a key storage location at any time such as at night or during a power outage. However, an object of the present invention is to provide a key storage device capable of extracting a key.

In order to achieve the above-mentioned object, a key storage device according to the present invention comprises a solar cell array, a storage battery charged by the solar cell array, and an emergency push button. It is provided with a solenoid driven by the power of the storage battery, and a lighting fixture lit by the power of the storage battery, mounted on a housing with a door, and unlocking the door by the solenoid. . More preferably, it is provided with an alarm which operates when the push button is pressed. In the key storage device of the present invention, when the surroundings are bright, the storage battery is charged by the solar cell array, the lighting device is turned on by the electric power, and the door is unlocked, so that at any time such as at night or during a power outage, Anyone can retrieve the key. Further, it is possible to widely notify that an emergency has occurred.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A key storage device according to an embodiment of the present invention will be described with reference to FIGS. 1 shows the appearance, FIG. 2 shows a state in which the door is opened, and FIG. 3 shows a circuit diagram. Install this key storage near a locked gate in a school or park. That is, the key storage device according to the present embodiment includes a solar cell array 1, a storage battery 3 charged by the solar cell array 1 through a charger 2, and a storage battery when the emergency push button 4 is pressed. 3 comprises a solenoid 5 driven by the power of the storage battery 3 and a lighting fixture 7 which is turned on by the power of the storage battery 3 via the photoelectric switch 6. These are mounted on the outer surface or inside of the housing 8. The key 9 is stored in the housing 8. The lock of the door of the housing 8 is opened by the solenoid 5. As the charger 2, a diode is simple and suitable. Like the fire alarm push button, the push button 4 is provided with a cover so as not to operate due to erroneous contact. The lighting fixture 7 is provided so that the location of the key storage device and the position of the push button 4 can be known even at night.
LED or EL is used. With the above-described configuration, when daytime sunlight is sufficient as a normal operation, the storage battery 3 is charged with power from the solar cell array 1. When there is no sunlight at night or the like, the output voltage of the solar cell array 1 decreases and charging is stopped. When the output voltage of the solar cell array 1 rises at dawn, charging is restarted. Repeat this every day. The capacity of the storage battery 3 is set to a capacity capable of storing a sufficient amount of electricity even in the absence of sunshine by referring to weather statistics. When the surroundings become dark, the photoelectric switch 6 is closed and the lighting fixture 7 is turned on. When the surroundings become bright, the photoelectric switch 6 is opened and the lighting fixture 7 is turned off. When an emergency occurs due to a disaster or the like, the push button 4 is pressed. As a result, the solenoid 5 is operated, the door of the key storage device is unlocked, and the key 9 stored therein can be taken out. At that time, the lighting fixture 7 is lit when it is dark at night or the like, so that the location of the key storage device can be easily understood, which is convenient for operating the push button 4 and removing the key 9. FIG. 4 shows a circuit configuration of a key storage device according to another embodiment of the present invention. The latching relay 10 which operates when the push button 4 is pressed, the off-delay timer 11 which operates by the operation of the latching relay 10 and opens after a predetermined time, and the off-delay timer 11
In addition, a rotation warning light 12 and a broadcast device 13 connected to the output contact of the above are added. Even with the addition of these appliances, the power is only consumed to a maximum during an emergency operation, so that the capacity of the storage battery 3 does not need to be particularly large. In addition, the rotation warning lamp 12 and the broadcaster 13 can notify a wide range of an emergency, and can also prevent operation by mischief.

The key storage device of the present invention makes it easy to find the key storage location at any time, such as at night or during a power outage, so that anyone can take out the key in the event of a disaster or the like.
