Abstract of the Disclosure A plug door assembly for closing an opening in a wall, comprising a door, first rail means mounted on the wall over the opening for use in longitudinally moving the door between an open position alongside the opening and adjacent the wall and an intermediate position opposite the opening. A pair of vertical crankshafts are rotatably mounted on the outer face of the door, the crankshafts extending past the upper and lower ends of the door. A low friction elongated carriage member is slidably mounted on the rail means above the opening, with the crankshafts being pivotally mounted in spaced journals provided in the carriage. One of the journals is in the form of an elongated slot such that the crankshaft received by the slot can travel along the longitudinal axis of the elongated carriage relative to the other crankshaft or shafts. Second rail means are pro- vided under the opening on the wall, and guide means on the lower ends of the crankshaft cooperate with the second rail means under the opening for guiding the door. The mounting means include means for laterally moving the door between the intermediate position opposite the opening and a closed posi- tion within the opening and a closed position within the opening in the plane of the wall. Locking means are also provided on the mounting means for cooperating with locking means on the wall to lock the door within the opening.
