Abstract

This invention provides a hingeless safe door assembly that can be flush mounted in a recessed safe compartment built into a wall or floor. Thus, a frame and flush cover plate holds the door assembly recessed away from the wall or floor for access to locking and latching mechanisms integral in the removable door. A latch bolt operating mechanism axially moves a master bolt, and other slave bolts are similarly axially moved by a pivoted lever that engages both the master and slave bolt for concurrent axial movement between latched and unlatched positions.
