Patent attributes
An elevator door apparatus includes an engaging device which engages car doors with hall doors. The engaging device uses a spring unit to urge a movable vane provided in each of the car doors. While the doors are moving, engaging rollers supported by the hall doors are sandwiched between the movable vane and a fixed vane. Thus, the driving forces of the car doors are transmitted to the hall doors. When the hall doors reach a door stop position, the movable vane is moved away from the fixed vane. Thus, the car doors are disengaged from the hall doors. At this time, a direction in which the elastic force of the spring mechanism acts is switched. Consequently, the car doors and the hall doors are stably held so that the car doors remain disengaged from the hall doors.
