Abstract

PURPOSE:To provide an illumination light device for an elevator which is designed in such a manner that earthquake control operation is carried out and, even if passengers should be left behind in a car, the passengers can leave the car with safety. CONSTITUTION:When an earthquake control operation device 30 is operated, a car is stopped at the nearmost floor, and earthquake control operation is completed, a relay 20 is energized, illumination lights L1 and L2 are lighted OFF, and a power outage light L3 is lighted ON. Measnwhile, a timer T is operated 10 minutes later, a contact Tb is opened, and the power outage light L3 is lighted OFF.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator lighting device.

[0002]

2. Description of the Related Art When an earthquake occurs, the elevator car that is running detects the occurrence of the earthquake so that passengers are not trapped inside the car due to the vibration of the building causing the elevator to stop between floors. The elevator is equipped with a seismic control operation device that stops the car at the nearest floor. After the operation of the seismic control operation device, the passenger remains in the open state for a predetermined time in order to remove the passenger from the inside of the car, and then the in-car illumination light is turned off and the door is closed. Consider the case where there are still passengers left,
Even if the light in the car is turned off, a lamp provided on a door opening button is lit so that the car can be safely exited from the car, and the user can go out by simply pressing the lit button.

[0003]

However, for example, if an old man who rarely uses the elevator uses an elevator alone and an earthquake occurs, it may be possible that he / she stopped at the nearest floor due to control operation. I couldn't understand and stayed in the car as it was.I didn't know what to do because of the darkness even though the car door light was turned off, even though the door button lamp was still lit. There is concern that it will be in a state.

An object of the present invention is to provide an elevator illuminating device which enables anyone to safely exit the car in the event of an earthquake.

[0005]

The above object of the present invention is to provide an elevator car equipped with an emergency power supply and a power failure light that is turned on only when there is a power failure, and an elevator car that is running by detecting the occurrence of an earthquake. An elevator illuminating device having an earthquake control operation device to be stopped on a floor and an extinguishing means for extinguishing an in-car illumination light provided in the elevator car when a predetermined time has elapsed after the stop on the nearest floor This is achieved by providing a lighting means for lighting the power failure lamp for a predetermined time by the operation of turning off the lamp.

[0006]

According to the above construction, even if the seismic control operation is performed at the occurrence of an earthquake and the illumination light in the car is turned off, the blackout lamp provided for the power outage lights up, so that the inside of the car may be dark. Even if a person who rarely uses an elevator, the power failure light ensures a certain level of brightness, so that the door opening button can be operated without hesitation and the user can safely exit the car. Further, since the power failure lamp is turned off after a predetermined time, for example, 10 minutes, it consumes less power, is charged immediately, and does not hinder the subsequent use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 is a front view of a car in which the lighting device according to the present invention is incorporated. In the figure, 1 is a car, 2 is a door, 3 is an operation panel provided on a side plate of the door 2, and 6
Is a door open button provided in the driver's panel 3, 4 is an indicator provided above the door 2, 5 is the ceiling of the car 1, and ceiling 5 has illumination lights L1 and L2 connected to an emergency power supply. And a power failure lamp L3 is provided between the illumination lamps L1 and L2.

FIG. 1 is an electrical connection diagram of the lighting device. In the figure, U and V are commercial AC power supply terminals, P1 and N1 are DC power supply terminals rectified by a diode D, and P2 and N2.
Is an emergency DC power supply terminal of a battery BA which is charged by the DC power supply terminals P1 and N1 via a resistor R.

Reference numeral 30 is an earthquake control operation device, and 20 is a relay that stops at the nearest floor by the control operation operation and opens the door 2 and closes the door 2 after a predetermined time to detect that the control operation is completed, 20a1, 20a2. Is a normally-open contact, 20b is a normally-closed contact, T is a timer which operates a predetermined time, for example, 10 minutes after the relay 20 is energized, and Tb is a normally-closed contact L1 or L2 of the car 1 described above. Illumination provided, L
3 is a power failure light.

Next, the operation of this embodiment will be described. When an earthquake occurs, the seismic control operation device 30 stops the operation car 1 at the nearest floor, opens the door 2 and lowers passengers, closes the door 2 after a predetermined time, completes seismic control operation, and activates the relay 20. It Then, the contact point 20b is opened, the illumination lamps L1 and L2 are turned off, the contact point 20a2 is closed, and the power failure lamp L3 is turned on brightly. On the other hand, the contact 20a1 is closed, the timer T starts counting, and after 10 minutes, the contact Tb is opened to open the power failure lamp L3.

Since the blackout light is still lit for 10 minutes even after the door 2 of the elevator is closed in this way, even if an unfamiliar passenger remains in the car 1, it is a little dark but the door open button 6 etc. The position and the like can be easily confirmed, and the passenger can operate the door opening button 6 to get out of the car 1 through the operation car 1. Further, since the power failure lamp L3 is only turned on for a short time, there is no particular problem.

[0013]

As described above, according to the present invention, since the seismic control operation is completed and the illumination lamp is turned off and the blackout lamp is turned on for a predetermined period of time, an unfamiliar passenger is left behind in the car. Even if this happens, the car is so bright that the door open button can be easily seen, and by operating this button, it is possible to get out and to prevent a trap accident. Further, since the power failure lamp is only turned on for a short time, there is no particular problem.
