Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Many devices are installed at the bottom of a hoistway of an elevator, that is, at a pit, and a pit check light device for illuminating the inside of the pit when inspecting these devices is provided. . Conventionally, this pit check light device uses a flashlight to check the position of the outlet in a dark place because the plug provided for the check light is inserted into the outlet provided on the pit wall and turned on. Had to be troublesome.

[0003] As an example of a means for solving the problem, a disclosure thereof can be found in Japanese Patent Application Laid-Open No. 7-247075.

[0004]

However, in the above-mentioned prior art, when the maintenance switch in the car is turned on and off, the check lights at the top and bottom of the car and the check lights in the pit are linked to be turned on and off. In addition, when only the stop switch is operated without operating the maintenance switch, or during normal operation, the pit check light cannot be turned on. In addition, when performing a visual inspection of the pit from the landing with a door with a glass window, etc., it is necessary to turn on the maintenance switch to turn on the pit check light, switching to maintenance operation and hindering the use of general users. was there.

The present invention has been made in view of the above-mentioned disadvantages, and has as its object the operability of turning on and off the pit check lamp from inside the car regardless of whether the maintenance switch is turned on or off.
An object of the present invention is to provide an elevator check light device excellent in safety.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an elevator inspection light device provided with an inspection light in a pit, and a dedicated switch for turning on and off the inspection light in the pit. Is installed in the car.

According to the present invention, the operability and safety can be improved by enabling the pit check light to be turned on and off from the car at any time regardless of the operation of the maintenance switch. it can.

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

FIG. 1 is a circuit diagram of a pit check light showing an embodiment of the present invention, and FIG. 2 is a layout diagram of the pit check light.

In FIG. 1, reference numeral 1 denotes an in-car operation panel, 2 denotes an in-car pit inspection light switch, 3 denotes a normally open contact of a not-shown car pit inspection light switch operation detection relay, and 4 denotes an in-pit inspection light.

In FIG. 2, 5 is an elevator car,
Reference numeral 6 denotes a landing door mounted on the lowest floor landing, 7 denotes a ladder for entering and exiting the pit, 8 denotes a pit, and 4 denotes a check light in the pit.

Next, the operation of this embodiment will be described. Now, when the pit check light switch 2 in the car is turned on, a pit check light switch operation detection relay (not shown) in the car is excited,
The normally open contact 3 closes. Thereby, P-3-4-N
The pit check light 4 is turned on. When entering the pit 8, the elevator car 7 is raised from the lowest floor, stopped between the lowest floor and the floor above it, and an opening fitting for unlocking the door from the lowest floor side. The door is unlocked by using, the lowermost floor door 6 is opened to prevent self-closing, and the ladder 7 is used to enter the pit 8. At this time, the inspection light 4 in the pit has already been turned on, so that the inspection work is started immediately after entering the pit 8. After the work in the pit 8 is completed, when the passenger gets out of the pit 8 and gets into the car, the pit check light switch 2 in the car is turned off. Opens, and the pit check light 4 goes out. Further, in the present embodiment, even when the work inside the pit 8 is not performed, if the car pit check light switch 2 is turned on regardless of the operation state of the elevator, the car pit check light switch operation detection relay (not shown) is excited. And
The normally open contact 3 closes. Thereby, P-3-4-N
And the pit check light 4 can be turned on. Further, the pit check light switch 2 in the car is turned off.
When F is pressed, the in-car pit check light switch operation detection relay (not shown) is demagnetized, the normally open contact 3 is opened, and the pit check light 4 is turned off.

[0013]

According to the present invention, since the check light device is configured as described above, the check light in the pit can be easily and safely turned on and off.
