Next, the outline of the operation of the control device 18 and the monitoring device 19 will be described with reference to FIG.
FIG. 6 is a flowchart for explaining an outline of the operation of the elevator control device and the monitoring device to which the elevator disaster prevention device according to the first embodiment is applied.

In step S1, the control device 18 determines whether or not a disaster has occurred. For example, the control device 18 determines whether or not an earthquake has occurred based on an earthquake detector provided in the building. If no disaster has occurred in step S1, the control device 18 performs the operation of step S1. When a disaster occurs in step S1, the control device 18 performs the operation of step S2. In step S2, the control device 18 determines whether or not the rescue operation mode is set.

If the rescue operation mode is set in step S2, the control device 18 performs the operation of step S3. In step S3, the control device 18 enables the disaster function of the disaster prevention device 14 to be used, and then displays information on how to use the disaster function on the display unit 22 of the car operation panel 13. Specifically, the control device 18 provides information indicating that the disaster prevention equipment can be used by rotating the main body 23b of the hollow body 23 after disconnecting the hollow body 23 by the pair of lock bodies 26 of the disaster prevention device 14. Is displayed on the display unit 22 of the car operation panel 13.

If the rescue operation mode is not set in step S2, the monitoring device 19 performs the operation of step S4. In step S4, the monitoring device 19 determines whether or not the power supply has been lost.

If the power is lost in step S4, the monitoring device 19 performs the operation of step S5. In step S5, the monitoring device 19 determines whether or not the SOS button 21d has been pressed.

If the SOS button 21d is not pressed in step S5, the monitoring device 19 performs the operation of step S5. When the SOS button 21d is pressed in step S5, the control device 18 performs the operation of step S3.

If the power supply is not lost in step S4, the monitoring device 19 performs the operation of step S6. In step S6, the monitoring device 19 determines whether or not the SOS button 21d has been pressed.

If the SOS button 21d is not pressed in step S6, the monitoring device 19 performs the operation of step S7. In step S7, the monitoring device 19 maintains the disaster function of the disaster prevention device 14 in an unusable state.

When the SOS button 21d is pressed in step S6, the monitoring device 19 performs the operation of step S8. In step S8, the control device 18 determines whether or not it is necessary to enable the disaster function of the disaster prevention device 14 based on the instruction from the information center device 20.

When it is necessary to enable the disaster function of the disaster prevention device 14 in step S8, the monitoring device 19 performs the operation of step S3. When it is not necessary to enable the disaster function of the disaster prevention device 14 in step S9, the monitoring device 19 performs the operation of step S7.

According to the first embodiment described above, the hollow body 23 is provided so as to be freely changeable between a state in which the disaster prevention product cannot be used and a state in which the disaster prevention product can be used as a handrail. Specifically, the hollow body 23 is formed by a pair of fixing portions 23a and a main body portion 23b. Therefore, with a simple configuration, disaster prevention supplies can be stored without reducing the effective area inside the car 8. At this time, the design of the inside of the car 8 is not impaired.

Further, the power generator 25 can generate electric power when the shaft body 24 rotates. Therefore, electric power can be easily generated by rotating the main body 23b of the hollow body 23 inside the car 8. The electric power at this time may be supplied to the rechargeable battery 29. The electric power at this time may be supplied to the display unit 22 of the car operation panel 13. The power at this time may be supplied to the user's mobile terminal. If the Internet network and telephone network are available, the power may be used for reporting or distribution of disaster information.

At this time, as information on how to use the disaster function, information explaining the power generation method by the power generator 25 may be displayed on the display unit 22 of the car operation panel 13.

The disaster control device 27 may be operated by the electric power from the generator 25 or the rechargeable battery 29. At this time, the car position detection sensor 17 may be operated by the electric power from the generator 25 or the rechargeable battery 29. When the disaster control device 27 determines that the car 8 is in a position where the car door 12 is permitted to open and close based on the detection result of the car position detection sensor 17, the electric power from the generator 25 or the rechargeable battery 29 is used. The car door 12 may be opened by driving the door motor. At this time, the landing door 10 opens following the car door 12. Therefore, even in the event of a power failure, it is possible to reliably avoid confinement of the user inside the car 8.

Further, in a normal state, one of the pair of lock bodies 26 connects one tip portion of the pair of fixing portions 23a and one end portion of the main body portion 23b. The other end of the pair of lock bodies 26 connects the other tip portion of the pair of fixing portions 23a and the other end portion of the main body portion 23b. Therefore, it is possible to improve the comfort of the user trapped inside the car 8 while preventing mischief during normal times.
