ABSTRACT:
Apparatus secures in its closed position the door of a chamber capable of maintaining pressure within the chamber. The present invention includes apparatus disposed on the chamber for cooperating to move the door to and from its closed position including at least two members, one of which is movable relative to the chamber. The door is in its closed position when the stationary member and the door are separated from each other by a predetermined distance. The movable member can be forced between the door and the stationary member to separate the door and the stationary member from each other by a predetermined distance. Further, the present invention includes apparatus for preventing the door from assuming its closed position until the movable member is forced between the door and the stationary member.
