Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this type, an actual flatbed 3
As described in No. 35982, if a passenger detection device is provided in the car and the presence of the passenger is detected by the passenger detection device, the turn-off circuit of the in-car illumination due to no call is invalidated, and the inside of the car is disabled. It is known that the lighting is kept on.

According to this conventional car interior lighting device, if the car is put in the car for cleaning the car inside the elevator, the car interior lighting does not go off even if the callless state continues for a predetermined time or longer. The work can be carried out with peace of mind, and it is possible to prevent an action such as pushing the emergency call button (emergency communication device) by mistakenly considering a power failure or a fault because the light was suddenly turned off during the cleaning work.

[0004]

However, it is difficult to accurately detect the presence of a person by providing only one passenger detection device. Therefore, a plurality of detection devices may be arranged in combination or the installation method may be devised. It is inevitable that the configuration becomes complicated.

It is an object of the present invention to provide a car interior lighting device for an elevator, which has a simple structure and can prevent the car interior lighting from being turned off during work in the car.

[0006]

[Means for Solving the Problems] The above object is to keep the lighting in the car turned on for a first predetermined time after the call disappears, and the no-call duration exceeds the first predetermined time. At this time, in the elevator car interior lighting device in which the car interior lighting is turned off, when the car interior closing button is pressed, the car interior illumination is linked with the closure button from the first predetermined time. This is achieved by providing lighting time extending means for lighting the second predetermined time which is also long.

[0007]

With the above construction, when cleaning the inside of the car, the operator enters the car and pushes the close button before the work. Then, the lighting time extension means operates, and the lighting time of the car interior lighting is longer than the lighting time when there is no call and the time required for the work, regardless of whether the car is called or not. It will never go out. As a result, it is possible to prevent an adverse effect or an adverse effect caused by turning off the light during work.

Embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2 are views showing an embodiment of the present invention, FIG. 1 is a circuit diagram, and FIG. 2 is a front view of the inside of an elevator car. As shown in FIG. 2, a destination floor selection button 3 is provided on a side plate 2 of a car on the side of an elevator door 1, and a closing button 4 for closing the door is arranged on the destination floor selection button 3. The close button 4 is provided with an interlocking timer 8,
When the user pushes the close button 4, the timer 8 is turned on. As shown in FIG. 1, a normally open contact 5a, a normally closed contact 10b and a relay 5 are provided between the power supply terminals P and N.
Are connected in series with each other. Here, the contact point 5a is a contact point of the relay 5, and the contact point 10b is a contact point of a relay (not shown) that is instantly excited during the car standby operation and demagnetized after a predetermined time. A switch 9a is connected in parallel to the contact 5a, and the switch 9a is a contact of a relay that is excited when a call is generated. Further, between the power supply terminals P and N, the normally open contact 5a of the relay 5 and the normally closed contact 8b of the timer 8 which is turned on by pressing the close button 4 are connected in parallel to each other, and the illumination in the car is connected to this. The lights 6 are connected in series. In addition, the contact 4a of the close button 4 in the car and the normally open contact 7a ₁ of the timer driving relay 7 are connected in parallel between the power terminals P and N, and the normally closed contact 8b of the timer 8 is connected to the contact 4a. The normally-closed contact 9b of the relay, which is excited at the time of occurrence of the call, and the timer driving relay 7 are connected in series with each other. The normally open contact 7a ₂ of the relay 7 and the timer 8 are connected in series. In the embodiment having such a configuration, the normally open contact 5a of the relay 5, the timer 8 and the contact 8b thereof constitute the lighting time extending means.

Next, the operation of the embodiment will be described.

In FIG. 1, the user gets in the elevator car and presses the close button 4. As a result, in FIG. 2, the contact 4a of the close button 4 is turned on. When the contact 4a is turned on, a closed circuit is formed by the power supply terminal P, the contacts 4a, 8b, 9b, the timer driving relay 7 and the power supply terminal N, and the relay 7 is formed.
Is self-held by the contact 7a ₁ . Further, the contact 7a ₂ of the relay 7 causes the timer 8 having a second predetermined time to
The N state is set. As a result, even when the passenger is in the car and the elevator is on standby,
It is lit while the timer 8 having a time limit of a predetermined time is turned on. Therefore, the user can work in the car without feeling uneasy even when the elevator is in the standby state. In addition,
When a call is generated after the close button 4 in the car is pressed, the timer drive relay 7 and the second predetermined time period are set by the contact 9b of the relay that is excited when the call is generated. The timer 8 is turned off, and the illumination lamp 7 becomes a circuit that is turned off by the 10b contact that operates after the first predetermined time.

As described above, because of the above-mentioned configuration, the lighting time extending means operates only when the user presses only the close button. Therefore, the user (worker) may be anxious about turning off the light during work. It can be resolved.

[0012]

As described above in detail, since the present invention has the above-mentioned structure, when the worker enters the car and presses the close button, the lighting time extending means operates and the call waiting standby state occurs. Since the light in the car is turned on for a longer period of time than when the above occurs, it is possible to prevent an adverse effect or an adverse effect caused by turning off the light during work.
