Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art An illuminating lamp is provided in a car of an elevator. Then, as disclosed in Japanese Utility Model Laid-Open No. 62-71155, in the operation panel under the operation panel, switches such as illumination lights, maintenance, stop, floor stop, fans, etc. operated by a manager or maintenance engineer. A cover is provided on the operation panel so that general passengers cannot use these switches, and the cover is normally locked.

[0003]

By the way, in a luggage elevator or the like, it takes time to carry in and out the luggage. Therefore, a user who is unfamiliar with the above-mentioned operation switch can open the door stop switch or the stop switch because the cover is unlocked. May be operated. Therefore, sometimes when the car is running, the user mistakenly turns off the light switch and the inside of the car goes into darkness, trying to turn on the light switch in a hurry, but when that special switch such as the stop switch is operated, the car is extremely There was a problem that a so-called canned food product failure occurred because the stopped product was trapped in the basket.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide an illumination device in a car of an elevator which can prevent the illumination lamp from being turned off even if the light switch is accidentally turned off while the car is traveling. To provide.

[0005]

The object of the present invention is to provide a lighting device in an elevator car having a light switch for turning on an illumination lamp in the car of the elevator provided in an operation panel in the car, when the car is activated. It is achieved by providing a relay that is energized and deactivates when the car stops at the destination floor and the door opens, and the normally open contact of the relay and the contact of the light switch are connected in parallel.

[0006]

According to the present invention, when the user unlocks the cover of the operation panel to carry the luggage, the illumination lamp is not turned off even if the light switch is accidentally turned off while the car is traveling. At this time, the user notices the operation error and normally turns on this light switch, but even if he does not notice this, the car stops at the target floor and the light turns off when the door opens, so the user does not operate correctly. You can turn on the light switch and be able to return to the normal state.

DETAILED 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 an elevator car. In the figure, 1 is a car, 2 is a door, 3 is an illumination lamp provided on the ceiling of the car 1, 4 is an operation panel, an operation panel 5 is provided below the operation panel 4, and the operation panel 5 is a cover 51. It is locked with a key 52 at all times.

FIG. 3 shows the operation switches of the operation panel 5. In the figure, a power switch 61, a manual switch 62, each floor stop switch 63, and a light switch 6 of the illumination lamp 3
4, a maintenance switch 65, a door stop switch 66, a stop switch 67, and a fan switch 68 are provided. Then, for example, when the lamp switch 64 is tilted upward, the illumination lamp 3 is turned on, when it is tilted downward, it is turned off, when the stop switch 67 is tilted upward, a normal state is set, and when it is tilted downward, if the car is traveling, The car is stopped and the car continues to be stopped.

FIG. 1 is an electrical connection diagram showing an embodiment of a lighting device in a car of an elevator according to the present invention. In the figure, U and V are AC 100V power supply terminals, 64a is a contact of a light switch 64, 3L is a lamp of an illumination lamp 3, and 10a is a normally open contact of a relay (not shown) that is energized while the car 1 is running.
Reference numeral 0a is a normally open contact of a relay (not shown) for detecting the closing of the door, 7 is an auxiliary relay, and 7a ₁ and 7a ₂ are normally open contacts thereof.

Next, the operation of this embodiment will be described. It is assumed that the user has opened the cover 51 of the operation panel 5 to carry the luggage.

Now, it is assumed that the user carries the luggage into the car 1 and starts the car 1. At this time, the contact 10a and the contact 40
Since a is closed, the circuit of the U-10a-40a-7- V is formed, the relay 7 is energized, is self-held by the contact 7a _1, contacts 7a ₂ are connected in parallel to the contact 64a. Therefore, in the car 1 is running, because the user can contact 7a ₂ also open the contact 64a to turn off the light switch 64 by mistake is closed, lamp 3L is lit continuously. When the car 1 arrives at the destination floor and the door is opened, the contact 40a is opened, the relay 7 is deenergized, the contact 7a ₂ is opened, and the lamp 3L is turned off. Therefore, the user notices that the light switch 64 is erroneously operated, and can restore the light switch 64 to the original state.

In this way, even if the car switch 1 is accidentally turned off while the car 1 is running, the illumination lamp 3 is not turned off, so that the erroneous operation of the stop switch and the maintenance switch can be prevented.

[0014]

According to the present invention, the illuminating lamp is configured so as not to be turned off even if the lamp switch is turned off while the car is traveling, so that the illuminating lamp is turned on even if the user accidentally turns off the lamp switch. There is. Therefore, there is an effect that a canning accident can be prevented without operating the stop switch or the maintenance switch.
