Abstract
An attic door rope apparatus for retractably storing an attic door rope may comprise a spool rotatably coupled with a rotation mechanism, and a stored-energy mechanism having a first end coupled with the spool and a second end coupled with the rotation mechanism, wherein the stored-energy mechanism is configured to impart a torque on the spool about a rotation axis of the spool. Another attic door rope apparatus for retractably storing an attic door rope may comprise a winding mechanism configured to rotate in an unwinding direction and a winding direction, a motor coupled with the winding mechanism configured to turn the winding mechanism in at least the unwinding direction, a sensor configured to detect a user command and send a command signal to the motor, and a power source in electrical communication with the motor and the sensor.
