Description

  The present invention relates to an elevator service disconnection operation device.

Conventionally, a timer switch that operates when a predetermined time zone is reached and a relay that is energized when all lights on the hall are extinguished are provided, and the timer switch is activated and the parking operation is performed only when the relay is energized. (See Patent Document 1).
Japanese Patent Laid-Open No. 5-97329 (paragraph numbers 0007 to 0015, FIGS. 1 and 2).

  According to the above prior art, if all floor lamps are not extinguished, the floor stops even if there are no users, so there is a problem that a third party may enter. It was.

  The present invention has been made in view of the above-described drawbacks, and an object of the present invention is to provide an elevator service disconnection operation device that improves the use efficiency of the user and has high crime prevention.

  In order to achieve the above-mentioned object, the present invention is provided with an elevator car serving a plurality of floors, a timer switch that operates only for a predetermined time period, and a predetermined switch of the car is automatically activated when this timer switch is operated. In the service disconnection operation device of the elevator that disconnects the operation to the floor, the elevator has a detection means for detecting that the illumination lamps provided on the floors of the plurality of floors are turned off, the detection means operates, and the timer It is configured to include means for performing service disconnection operation when the switch is activated.

  According to the present invention, it is determined that there is no user when the lighting on the predetermined floor in the building is off, and the service is disconnected only on the floor where the lighting is off. There is an effect that can improve the use efficiency and crime prevention.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an electrical connection diagram showing an embodiment of the present invention, and FIG. 2 is a sectional view of a hoistway.

  In FIG. 2, 1 is a hoistway, 2 is a cage, 31 to 39 are landings from the first floor to the ninth floor, 41 to 49 are landing doors from the first floor to the ninth floor, and 51 to 59 are provided at the landings 31 to 39. It is an illumination light.

  In FIG. 1, P and N are DC power supply terminals, 51b to 59b are normally closed contacts of contactors for turning on the lamps 51 to 59, and 21 to 29 are relays for detecting that the floor lights are turned off. , 21a to 29a are normally closed contacts, 11 is a first predetermined time, for example, a timer switch which closes the contact 11a at 10 o'clock in the evening, and opens when the time elapses at 6 o'clock in the morning, 61 Reference numerals -69 denote service disconnection circuits.

  Next, the operation of this embodiment will be described.

  At 10 o'clock in the night, that is, at the first predetermined time, the timer switch is activated and the contact 11a is closed. At this time, since the contact 51b is closed when the illumination lamp 51 of the hall 31 is turned off, the relay 21 is energized, the contact 21a is closed, and the service disconnection circuit 61 disconnects the service on the first floor. At the second predetermined time, ie, 6:00 in the morning, the contact 11a of the timer switch 11 is opened, so that the relay 21 is deenergized, the contact 21a is opened, the service disconnection circuit 61 is shut off, and service to the first floor is possible. Become.

  Next, when the first predetermined time, i.e., 10 o'clock in the evening, there are still users on the 9th floor, and the lighting 59 on the 9th floor is lit, the contact 59b is open and the relay 29 is Not energized. Therefore, since the service disconnection circuit 69 is not energized, the 9th floor service disconnection operation is not performed, and the elevator services the 9th floor. Thereafter, when all the users on the 9th floor leave and the illumination lamp 59 is turned off, the service on the 9th floor is disconnected in the same manner as described above.

  As described above, when the user is on the floor, the circuit configuration is such that the service disconnection operation is invalidated even during the time period in which the service disconnection operation is performed, so that the service of the user can be prevented from being deteriorated.

  In addition, although the presence or absence of the user was judged by lighting and extinguishing of the lighting lamps 51 to 59 of the hall, an office lighting lamp can also be used. Also, if the hall lights 51 to 59 are turned off and the car 31 cannot enter the car 2 from the halls 31 to 39, the relays 21 to 29 are replaced with timers so that the service can be switched off after a predetermined time, Only calls may be disconnected.

  Further, although one timer switch is provided for all floors, a timer switch may be provided for each floor so that the time zone can be set for each floor.

It is an electrical connection diagram which shows one Embodiment of this invention. It is sectional drawing of the hoistway of an elevator.
