Abstract: An insulated fire door includes a door shell having spaced first and second exterior panels and a gypsum panel between the first and second exterior panels. The insulated fire door includes a plurality of spacers bonded across an interior side of each of the first and second exterior panels. The spacers maintain the gypsum panel in a spaced position from the interior sides of the first and second exterior panels as the door bows during a fire on one side of the door, until the gypsum disintegrates. Each of the spacers may have a flat portion contacting the gypsum panel, a leg extending from the flat portion spacing the gypsum from the interior sides of the first and second exterior panels, and a flange extending from the leg bonding the spacer to the first and second exterior panels.

Abstract: An insulated door comprising a door shell having spaced first and second exterior panels. The door includes a plurality of stiffeners bonded to a liner panel, with thermal insulation between adjacent stiffeners, disposed within the door shell. The liner panel may extend along one side of the stiffeners and the thermal insulation along the liner panel between the stiffeners and the first and second exterior panels. The stiffeners and the liner panel are preferably made of steel and the stiffeners are welded to the liner panel. The stiffeners are preferably not welded to the first and second exterior panels of the door shell. The liner panel is preferably insertable into the first or second exterior panels of the door shell. The insulation material fills substantially all of the space between the liner panel and one of the first or second exterior panels.

Abstract: A welded door frame assembly including a hinge jamb joined to a lock jamb via a frame head jamb, all of which are joined with existing studs and an existing wall. The hinge jamb has a bottom end and a top end and includes a door side base, a door contact flange, and a non-door side trim attachment track including one or more fastener holes. A hinge jamb trim piece includes a connector portion configured to be removably retained within the non-door side trim attachment track and is adapted to cover the non-door side trim attachment track, any fastener holes, and any fasteners. Both the lock jamb and frame head jamb include a door side base, a door contact flange, and a connection flange including one or more fastener holes. A lock jamb or frame head jamb trim piece covers the connection flange, any fastener holes, and any fasteners.

Abstract: A contiguous emergency exit path lighting system that includes the peripheral lighting of a hollow doorframe at an egress point using a set of electroluminescent illuminators integrally formed within or upon the doorframe, an electrical bypass doorframe to reroute wiring around doorways that are not points of egress, electroluminescent illuminator strips mountable on walls, floors, and other pathway surfaces, and flush mount exit signage on the egress door to enhance visibility in high smoke and high heat applications. An integrally formed U-shaped channel within the egress doorframe secures a transparent or translucent raceway tube that encloses the electroluminescent strips.

Abstract: A pass through closure and delivery device permitting material to be safely passed through a slot in a partition or prison cell door. A container having first and second openings and first and second doors associated with each opening is disclosed for mounting on a partition or cell door having a slot therethrough. Each door on the container includes a latch that is operable from only one side of the cell door. A cam-operating attaching mechanism allows the container to be releasably mounted to a pair of track members affixed to the cell door with the slot therebetween. Using the pass through delivery device and the method of the present device, food or other materials can be safely delivered to an inmate inside a locked cell by mounting the container of the pass through delivery device on the cell door with one of the openings adjacent the first door covering the slot in the partition.
