Abstract
A door closure mechanism comprising a frame and sliding door adapted to close a doorway to effect a shield against electromagnetic radiation and other environmental conditions. The sliding door is suspended for lateral movement and is adapted to bear against the frame and be secured to it to effect a seal.
Claims14
A door closure mechanism comprising:
- a door frame defining a doorway;
- a track secured above said door frame;
- a door having peripheral frame members;
- means connected to the upper portion of the door and slidable in the track whereby the door hangs from the track and is slidable to a first position coinciding with the door frame and to a second position to open the doorway;
- a plurality of movable means secured to the door frame on the periphery thereof;
- a plurality of cooperating means equal in number to the movable means secured to the periphery of the door and adapted to cooperate with the plurality of movable means when the door is in the said first position;
- resilient strip means secured to the periphery of the door;
- and
- means to activate the movable means to engage the cooperating means on the door to move the door laterally against the door frame whereby the resilient strip means is gripped between the door and the door frame to provide a radiation resistant joint.
