Abstract: An elevator car is provided and includes a car frame which translates along a guide rail during ascents or descents, a safety disposed along the car frame to selectively engage with the guide rail to selectively permit vertical elevator car movement, an electronic safety actuator (ESA) and a control system. The ESA actuates the safety and includes an ESA body secured to the car frame with horizontal maneuverability and defining a groove through which the guide rail translates during the vertical elevator car movement, a magnetic guide operably disposed within the groove to exert magnetic force on the guide rail and a sensor disposed within the groove to sense horizontal distance between the guide rail and corresponding portions of the ESA body. The control system controls the magnetic guide to exert a magnetic force in accordance with reading of the sensor to maneuver the ESA body horizontally.

Abstract: Elevator toe guard assemblies are provided. The elevator toe guard assemblies include an elevator car frame, a buffer located within an elevator shaft, and a toe guard mounted to the elevator car frame. The toe guard has a first state being a fully extended state, a second state wherein the toe guard does not contact a pit floor during operation of an elevator car, and a third state wherein at least a portion of the toe guard is moved relative to the elevator car frame during an impact between the buffer and the pit floor.

Abstract: An elevator car (42; 103) for carrying a load in a vertical direction. The elevator car includes at least one elevator car door (38) carrying a door coupling (20) and a camera mount (40) comprising a mounting location (46) for a camera (44). The camera mount (40) is located at the top of the elevator car (42) with the mounting location (46) positioned for a camera (44) to monitor the door coupling (20). The camera mount is deformable at least in the vertical direction, when acted on by a downwards force, such as to protect the door coupling (20) from being impacted by the camera mount (40).

Abstract: An elevator car (1) comprises a working platform (4) moveable between a stowed position, at an upper part (3) of the elevator car (1), and an operational position, suspended from the upper part (3) of the elevator car (1) to be inside the elevator car (1). At least one stop (6a, 6b) is located at the upper part (3) of the elevator car (1). The at least one stop (6a, 6b) is moveable between a retracted position and a deployed position. In the deployed position, the at least one stop (6a, 6b) extends away from the upper part (3) of the elevator car (1) to provide an upper safety space (53) above the elevator car (1).

Abstract: Elevator systems are described. The elevator systems include an elevator car movable along guide rails along an elevator shaft, the car having a platform, a ceiling, and car structural members, with car panels arranged to define a cab, and a car operating panel therein. An overspeed safety system includes first and second safety brakes and electromechanical actuators, with the brakes operable to engage with the guide rails to stop movement of the elevator car. A control system is operably connected to the electromechanical actuators and configured to trigger the electromechanical actuators due to at least a detected overspeed event. The control system is located on top of the ceiling, within the ceiling, beneath the platform, within the platform, behind a car panel, or within the car operating panel.
