Quick-acting, water-tight composite door assembly

摘要

A door assembly includes a main door body with an interior flange and an exterior flange, both extending parallel and generally away from the main door body. A door frame surrounds the door body when the latter is in a closed position, the door frame having an inner and outer flange, both of the latter extending generally toward the main door body when in its closed position. Two gaskets are provided between a flange of the door frame and a flange of the door, whereby movement of the main door body in a given direction generally perpendicular to the direction in which the flanges extend causes the gasket to be compressed. One of the flanges of the door has a plurality of spaced-apart compression members, for each of which a latch member is provided, each latch member having a pressure component and being mounted to the door frame for movement between a first position in which the pressure component presses against the respective compression member in the direction which compresses the gasket, and a second position in which the pressure component does not press against the compression member. Finally, a linkage assembly interconnects all latch numbers and moves them in tandem between their respective first and second positions. The linkage assembly includes operating means for operating the linkage assembly.
