Abstract
Two or more panels of a power-operated folding door are supported by a novel articulated arm assembly that ensures that the door closes tightly against a wall-mounted seal and easily opens. The articulated arm assembly includes a connector with two spaced-apart pivot points about which two adjoining arms of the assembly can rotate as the door opens and closes. The two pivot points allow the panels to readily fold up and store more compactly when the door is open. To provide an airtight seal where two leading panels come together at the center of the doorway, one or more control mechanisms coupled to the articulated arm assembly ensure that the leading panels overlap when the door is closed.
