ABSTRACT:
A locking mechanism for securing a door of a safe within a frame includes a drive gear rotatably mounted on the interior surface of the door. An extension fitted with a rack gear is mechanically cooperated with the drive gear. The extension is adapted to be slidingly displaced along the interior surface of the door so as to extend outwardly from a corner of the door and be detachably engaged or abutted against the inwardly facing side of a door frame, more specifically, a corner of the door frame. The intercooperation of the extension and the frame forms a securement of the door and particularly the corner of the door within the door frame.
