JPH05147832A - Luminaire for elevator - Google Patents

Abstract

PURPOSE:To prevent a person from stumbling over a step difference generated between an elevator car and a hall side. CONSTITUTION:In a luminaire 4, a switch-off condition is determined such that after an illumination switch 3 is operated in the switch-off direction a person goes out to the hall side after crossing a person detecting sensor 5 positioned in the vicinity of an exit of an elevator car 1, while a switch-on condition is that a person enters the car 1 after crossing the person detecting sensor 5 positioned in the vicinity of the car 1.

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 Conventionally, as described in Japanese Utility Model Laid-Open No. 62-71155, an illuminating body that can illuminate is provided near a switch and a name plate in an operation panel in a car so that an elevator is normally operated. When the illuminating body is off and the light switch is turned off, the illuminating body is turned on to prevent erroneous operation of the switches even when the inside of the car becomes dark.

[0003]

The above-mentioned prior art has taken into consideration the prevention of erroneous operation due to the inside of the car becoming dark after the lighting device is turned off. However, in general, after the lighting device is turned off, maintenance is performed. In many cases, staff members or managers get on and off the car, and at that time the car is dark, so if there is a step on the hall side of the car due to a level error, etc., people may stumble.

An object of the present invention is to provide an elevator illuminating device which can prevent a person from tripping over due to a step generated on the side of a car and a hall.

[0005]

SUMMARY OF THE INVENTION The above-described object is to provide an in-car operation panel that accommodates various switches including a lighting switch, and a lighting device that turns on and off in conjunction with the lighting switch, and In an elevator lighting device equipped with a person detection sensor in the vicinity of a car exit, after turning off the lighting device in the turning-off direction of the lighting device, a person crosses the person detection sensor in the vicinity of the car exit. This can be achieved by being on the hall side.

[0006]

In the car lighting device, the light switch in the operation control panel is operated in the direction of turning off the light, and the sensor near the car is turned off by a person blocking it, and when the light is on, the sensor is also turned on. Lights when a person blocks it. As a result, the light in the car is always lit when people get on and off, which is safe for getting on and off.

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

FIG. 1 is a sectional view of a hall showing an embodiment of the present invention, FIG. 2 is an operation circuit diagram of a lighting device, and FIG. 3 is an operation timing chart of a person detecting sensor circuit.

In FIG. 1, 1 is a car, 2 is a car operation control panel, 3 is a lighting switch in the car operation control panel, 4 is a lighting device, and 5 is a person detection sensor provided on the hall side. .. In FIG. 2, 3 is a lighting switch in the car operation panel,
4 is a lighting device, 6 is a relay that operates when the lighting switch 3 is on the input side, 6a is a contact of the relay 6, 7 is a relay that operates when the lighting switch 3 is off, 7a is a contact of the relay 7, and 8 is a hall. A sensor circuit that operates in conjunction with the sensor 5 provided on the side, 8a is a relay contact of the sensor circuit 8, and 9 is a contact 7
Reference numeral 9a is a contact of the relay 9 which operates when a is closed and the contact 8a is closed.

Next, the operation of this embodiment will be described.

When a maintenance person or a manager in the car turns the lighting switch 3 in the car operation control panel 2 to the off side, the relay 7 that operates when the lighting switch is in the off side operates to contact the contact 7a. Is closed and the contact 8a is also closed in the initial state, the relay 9 operates and the contact 9a is closed, so that the lighting device 4 continues to light.

In this state, when the maintenance person or the manager goes out of the car to the hall side, the person detection sensor 5 detects the person, and the sensor circuit detects the person, so that the contact 8a opens. As a result, the relay 9 ends its operation, so that the lighting device 4 is also turned off.

Next, when the maintenance staff or the manager tries to get in the car again, the person detecting sensor 5 detects the person,
When the sensor circuit detects a person, the contact 8a is closed, whereby the relay 9 is operated and the contact 9a is closed, so that the lighting device 4 is turned on. When a maintenance person or a manager who gets in the car turns the lighting switch on, the relay 6 operates and the contact 6a closes, so that the lighting device 4 continues to light regardless of whether the person gets on or off.

According to this embodiment, even when the maintenance person or the administrator turns the lighting switch to the off side, the lighting is turned on until the passenger gets off the car, so a stumbling occurs because the inside of the car is dark. Accidents can be prevented.

[0015]

According to the present invention, when a person gets in or out of a car, the illumination is always turned on, so that there is an effect of preventing a stumbling accident or the like which occurs due to the dark inside of the car.
