Abstract:
In a fire-resistant safe having an inner shell and an outer shell, the shells each having walls encapsulating a space to be filled with insulation material, the improvement comprising:at least one funnel part formed by a wall of one of the shells and defining an opening for filling the encapsulated space, the funnel part comprising opposing side walls projecting outwardly from the one shell, the side walls defining an outer surface; an escutcheon part adapted for placement over and enclosing the one funnel part, the escutcheon part having side walls defining an inner surface and an outer rim, with the outer surface of the funnel part side walls at least partially abutting the inner surface of the escutcheon part when the escutcheon part is placed over the funnel; the surface of one of said parts defining a locking groove extending parallel to the shell wall forming the funnel part and an insertion groove extending laterally outwardly from the shell wall forming the funnel part and intersecting the locking groove, each of the grooves having a length parallel to the shell wall with the locking groove length greater than the insertion groove length; and the surface of the other of said parts defining a rigid locking member insertable into the insertion groove when the escutcheon part is placed over the funnel part and repositioned in the locking groove when the escutcheon part is moved parallel to the shell wall to a locked position, the locking member and the locking groove holding the rim of the escutcheon part firmly against the shell wall and preventing axial movement of the escutcheon part, wherein the rigid locking member cannot be removed from the locking groove in which it is placed except by movement of the rigid locking member parallel to the shell wall, and wherein the improvement includes means for preventing the rigid locking member from moving parallel to the shell wall once the escutcheon part is in the locked position.
