  • Patent number: 10882717
    Abstract: An emergency operation controller for an elevator is connected to other emergency operation controllers of their respective elevators through network, and each controller constitutes a node in the network. The controller generates and transmits an emergency condition detection message to other controllers in the network which constitute adjacent nodes to the controller when the controller detects an emergency condition, and receives an emergency condition detection message from other controllers which constitute adjacent nodes to the controller in the network when other controllers detect an emergency condition. The emergency condition detection message includes a propagation count. The propagation count is configured to be decremented by one, each time one controller transmits the emergency condition detection message to other controllers which constitute next adjacent nodes. The emergency condition detection message is continuously transmitted until the propagation count reaches to zero.

  • Patent number: 10669125
    Abstract: An elevator rope guide system comprises a plurality of rope guides for restricting the swaying of at least one main rope and a plurality of stop mechanisms each configured to stop a corresponding rope guide. The rope guides are located above an elevator car and/or counterweight and are vertically movable along a hoistway. The stop mechanisms are positioned at different intermediate heights along the hoistway. The elevator rope guides are collected by the elevator car or counterweight as the elevator car or counterweight moves up and are stopped by a corresponding stop mechanism as the elevator car or counterweight moves down.

  • Patent number: 10526172
    Abstract: A mechanical hoistway access control device for an elevator landing door includes a first blocking member mounted on a position on a landing door frame above a landing door, and a second blocking member mounted on a position on a car door frame above a car door. The first blocking member is pivotably attached between an upright position and a first horizontal position extending in the door opening direction about a horizontal shaft. The second blocking member is pivotably attached between an upright position and a second horizontal position about a horizontal shaft, the second horizontal position being where the second blocking member protrudes out to the landing door side to block movement of the first blocking member.
