  • Patent number: 5045636
    Abstract: An EMI/RFI shielded door assembly for use in controlling the movement of EMI/RFI in a shielded room or enclosure. The assembly has an electrically conductive frame defining a generally rectangular opening. A conductive door stop is formed on the inner surfaces of the top and side members of the frame to form a pocket into which a shielded door may be held when in its closed position. The threshold of the frame is preferably flat. A series of cam or drop hinges are used to mount the door to the frame. The hinges cause the door to be raised or lowered to or from the threshold as it is rotated on the hinges from a closed to an open position and vice versa. A low closure force gasket, e.g. less than 5 pounds per linear inch preferably formed of a conductive elastomer, is used to fill any gap that may exist between the door and the frame.
