Abstract
A door assembly for an EMI shielded room includes a door structure defining an inner space parallel to the door faces. Plates are mounted in the space for movement toward and away from the door edges. Support and guide assemblies precisely regulate the plate movement. Either a pneumatic bladder, or a camming system, spaced inward from the door edges forces the plates to move outward from the door edges and parallel with the door plane. Return springs retract the plates when either the bladder is deflated, or the camming system is manipulated back to an at-rest position. The outer borders of the plates carry bumpers that force flexible contact members into engagement with the jamb and threshold of a doorway.
