Abstract

Abstract A locking mechanism for use in a mechanized filing cabinet having a position adjustable posting board and a vertically sliding door for closing an access opening. The posting board is moved to a predetermined position and a release handle is moved inwardly to cause shoot bolts to move outwardly and lock the posting board at the predetermined position. The vertically sliding door is moved downwardly to close the access opening in the filing cabinet and a locking key is rotated to move lock bolts outwardly. Movement of the lock bolts locks the release handle and moves latches into apertures in the sliding door thereby locking the sliding door in its lower or closed position.
