  • Publication number: 20230121073
    Abstract: An illustrative example embodiment of an elevator includes an elevator car and a drive mechanism connected with the elevator car. The drive mechanism moves with the elevator car in a vertical direction. The drive mechanism includes at least one drive member that is configured to engage a vertical structure near the elevator car, selectively climb along the vertical structure to cause movement of the elevator car, and selectively prevent movement of the elevator car when the drive member remains in a selected position relative to the vertical structure. A biasing mechanism urges the drive member in a direction to engage the vertical structure. The biasing mechanism applies a biasing force based upon a condition of the elevator car. The biasing force changes based upon a change in the condition.

  • Patent number: 11542123
    Abstract: An illustrative example embodiment of an elevator system includes a cab configured to accommodate at least one passenger or item inside the cab. A motorized module includes a base, a connector supported on the base and at least one drive member supported on the base. The connector is configured to selectively establish a releasable connection between the motorized module and the cab. The drive member is configured to engage a vertical surface, climb along the vertical surface to selectively cause vertical movement of the base, and selectively prevent movement of the base when the drive member remains in a selected position relative to the vertical surface. At least one motor is associated with the drive member to selectively cause the drive member to climb along the vertical surface. The motorized module is vertically movable independent of the cab when the motorized module is released from the cab.

  • Publication number: 20210395038
    Abstract: An aspect includes a system with a communication interface configured to receive a mobile device location indicator at a first location and a second location. The system also includes a memory system and a processing system configured to perform operations. The operations include detecting a mobile device at the first location and observing a current state of one or more conditions present during detection of the mobile device. A travel prediction of the mobile device between the first location and the second location is determined based on a travel history of the mobile device and the current state of the one or more conditions. A command is output to a dispatching system based on detection of the mobile device at the first location and the travel prediction of the mobile device to align with a predicted arrival of the mobile device at the second location.
