Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing an operator from forgetting to turn off an inspection light of an elevator.

[0002]

2. Description of the Related Art Conventionally, as this type, for example, as disclosed in Japanese Utility Model Laid-Open No. 58-20260, an operation panel necessary for an elevator maintenance work, that is, a stop, is provided on an operation panel in an elevator car. It is known that switches such as operation, door stop operation, floor stop operation, car illumination lamp, car ventilation fan, maintenance inspection, and inspection light are provided, each of which can be turned on and off independently.

It should be noted that these switches are covered and locked so that general passengers do not operate these operation switches.

[0004]

By the way, the inspection light is
It is installed above and below the car, and when inspecting equipment in the hoistway, it is always lit because the hoistway is dark. Therefore, when carrying out maintenance and inspection of equipment in the hoistway by riding on the car, an expert opens the cover of the operation panel, turns on the maintenance switch and the inspection light switch, and switches from normal operation to maintenance operation and performs inspection. I turn on the lights and then work on the car. After finishing the work, return to the car and turn off the maintenance switch and inspection light switch, all the work will be completed, but if you forget to turn off the maintenance switch, you will notice immediately because it moves differently from normal operation,
When the check light switch is forgotten, there is no difference in the movement of the elevator, and therefore there was a problem that the check light switch was forgotten and the check light continued to light.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator inspection light forgetting prevention device which can prevent the inspection light from continuing to light even if the inspection light switch is forgotten to be turned off.

[0006]

The above object is to inspect an elevator having a plurality of operation switches including an inspection light switch in an elevator car and having an inspection light that is turned on and off by opening and closing the inspection light switch. In the prevention device for forgetting to turn off the light, a timer having a contact that starts when the inspection light switch is turned on and opens after a predetermined time has elapsed is provided, and the contact of the timer is interposed between the inspection light and the power source. To be achieved.

[0007]

With the above-mentioned configuration, in order to perform inspections,
When the inspection light switch is turned on, the inspection light is turned on and the timer is started, and when a preset predetermined time elapses, the contact is opened and the inspection light is turned off. Therefore, if the time required for inspection, etc., is less than the timer's set operation time at the start of inspection, etc., leave it as it is, and if it is longer, reset the timer's operation time according to the time required for inspection, etc. For example, if you forget to turn off the check light switch and remain in the on state, the check light will turn off after a predetermined time.

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

FIG. 1 is a circuit diagram showing an embodiment of the present invention, and FIG. 2 is a sectional view showing an inspection state by a car inspection light.

In the figure, reference numeral 1 is an inspection light, which is provided above and below the car 2. Reference numeral 3 is an inspection lamp switch among various operation switches provided on the operation panel in the car 2, 4 is a timer, and 4b is a normally-closed contact of the timer 4, which opens after a predetermined time has elapsed since the timer 4 was started. The inspection light switch 3, the contact 4b and the inspection light 1 are connected in series with each other and are interposed between the power sources P and N. The timer 4 is connected in series with the check light switch 3 and is interposed between the power supplies P and N.

Next, the operation will be described.

When inspecting the inside of the hoistway, the inspection light switch 3 in the car 2 is turned on. At this time, the timer 4 is started, but the normally closed contact 4b is closed for a predetermined time.
The check light 1 is turned on. After that, move the car 2 over the car 2 and inspect the inside of the hoistway. When the inspection in the hoistway is completed, descend from the top of the car 2 and turn off the inspection light switch 3 in the car 2. As a result, the inspection lamp 1 is turned off and the timer 4 stops counting time and is reset.

However, when the inspection lamp switch 3 is forgotten to be turned off after the inspection of the hoistway, the timer 4 continues counting the time, and after a lapse of a predetermined time, the normally closed contact 4b opens.
As a result, the inspection lamp 1 is de-energized and turned off.

Therefore, even if the inspection light switch 3 is forgotten to be turned off, it can be prevented from turning off and continuing to light up after a predetermined time.

If the predetermined time of the timer 4 is set in accordance with the required time for inspection or the like, it will not be turned off during the work such as inspection.

[0016]

As described above, according to the present invention, when an inspection lamp switch is turned on to perform an inspection or the like, the inspection lamp is turned on and a timer is started. Opens and the check light goes out.
Therefore, if the time required for inspection, etc. is within the set operation of the timer at the start of inspection, etc., leave it as it is, and if it is longer, reset the operating time of the timer according to the time required for inspection, etc. Even if the inspection light switch is forgotten to be turned off and remains in the closed state, the inspection light is turned off after a predetermined time, so that it is possible to prevent forgetting to turn it off.
