運転休止状態となつている。 On the other hand, a parking device may be provided for the elevator. In an elevator equipped with a parking device, when a parking relay is activated when stopping operation of the elevator at night, a car is guided to a predetermined floor and parked at the predetermined floor. Therefore, during the elevator outage period at night, the elevator is parked at a predetermined floor and is out of operation.

遮断して電気工事を行なうことがある。<Problem that the invention aims to solve> When electric power companies cut off the power at night to carry out electrical work, it is not necessary to cut off the power for the elevators since the elevators are out of operation. Electrical work may be carried out by cutting off the power supply to the elevator without contacting the elevator manager, thinking that there will be no problem.

工事が長時間にわたると、蓄電池が放電し尽して
しまうことがある。 When the power supply for the elevator is cut off, the lighting device of the elevator parked at a predetermined floor is activated, and the power outage light in the car is turned on by the storage battery. The power outage light will remain on until the electrical work is completed and the power for the elevator is turned on again, so if the work continues for a long time, the storage battery may become completely discharged.

とがある。 In such a state, not only the storage battery deteriorates, but also it takes time to charge the storage battery even if the elevator power is turned on again. Therefore, when a power outage accident occurs for an elevator that has started operating, a situation may occur in which a power outage light is not turned on and emergency induction operation using a storage battery is not possible.

供することにある。 This idea was made in view of the current state of the conventional elevator power outage light device mentioned above, and its purpose is to switch off the elevator power supply when the elevator is guided to a predetermined floor by the parking device and is in the parking state. To provide a power outage light device for an elevator configured so that the power outage light does not turn on even if the power outage light is cut off.

る。<Means for solving the problem> In this invention, when the car is guided to a designated floor and parked by the activation of the parking relay, the voltage of the parking device is shut off, and when the interruption of the AC power supply is detected, the voltage of the storage battery is shut off. A normally closed contact that opens when a parking relay is activated, and a normally open contact that closes when interruption of the alternating current power source is detected, for an elevator equipped with a lighting device that supplies power to a power supply lamp and turns on a power outage light. The elevator power outage light device is configured by connecting the power outage light in series between the power supply of the storage battery and the power outage light.
