  • Patent number: 7604096
    Abstract: An operating apparatus for an elevator is equipped with a landing chair having a storable seat portion and provided at a landing, a landing chair displacement device for displacing the seat portion, and a control device for controlling the landing chair displacement device. The seat portion can be displaced between a landing chair storage position and a landing chair service position allowing a passenger to sit. The landing chair displacement device performs a storage execution operation of displacing the seat portion from the landing chair service position to the landing chair storage position to hold the seat portion at the landing chair storage position, and a storage releasing operation of releasing the seat portion from being held at the landing chair storage position. The control device has landing chair control means for controlling the landing chair displacement device based on information from operation detecting means for detecting an operational state of the elevator.

  • Publication number: 20090255761
    Abstract: An elevator control system is equipped with an evacuation operation control portion. In the event of a fire, the evacuation operation control portion determines, based on information on the fire and an elevator, whether or not the evacuation operation of the elevator can be performed. When it is determined that the evacuation operation can be performed, the evacuation operation control portion outputs a command to perform the evacuation operation to an elevator control device. Further, a condition for determining whether or not the evacuation operation can be performed is set in the evacuation operation control portion.

  • Publication number: 20090038891
    Abstract: A building is provided with an elevator and evacuation stairs. Each floor is separated into an elevator region in which the elevator is provided and a stair region in which the evacuation stairs are provided. In an event of a fire in the building, an evacuation assistance device for the elevator sets a predetermined service floor as a rescue floor, and supervises an operation of the elevator so as to convey those stranded in the building from the rescue floor to an evacuation floor. A rescue floor crowdedness detecting device detects crowdedness or uncrowdedness of the elevator region at the rescue floor. An evacuation guidance device for reporting to those stranded in the building accessibility information representing the accessibility of those stranded in the building to the elevator region at the rescue floor from the stair region is installed in the building. Information from the rescue floor crowdedness detecting device is transmitted to an emergency control device.

  • Publication number: 20080202861
    Abstract: In a fire control system for an elevator, the time for the fire and smoke to reach the elevator hall of each floor of a building during fire is pre-calculated as the evacuation time of the floor. When the evacuation time of a floor is longer than the time for making a car respond to a rescue call from the evacuation floor, the floor is judged as a rescue floor, and when shorter, the floor is judged as a non-rescue floor. Furthermore, the order in which the rescue is carried out among the rescue floors is determined. Accordingly, it is possible to rescue remainders on a rescue floor using an elevator as an evacuation means. Moreover, since rescue operation by the elevator is performed with the order of rescue determined, rescue operation suitable for the conditions of the fire can be realized.
