A sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (“HEMP”). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

A door assembly may include a first sidelite configured to be operably coupled to a first door jamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.

A door assembly is shown and described herein. The door assembly may include at least one door panel and a door frame having a plurality of frame members including a header and a mullion. The invention may also be considered a frame member. The frame member may be a mullion and include a core; and a two-piece top piece adjoining the core to form a structural member. The door assembly may further include at least one adjacent panel. The inventions disclosed are also applicable to jambs and window structures. Also disclosed are methods and assemblies for a mullion door frame member.

A high security two-way virtual cross-barrier observation and communication device has a mounting frame with a hardened core, a pair of digital displays, and a pair of cameras. The mounting frame may correspond to a typical interior door of a building or a relevant component of a vehicle, aircraft, or other relevant application. The hardened core is bullet-resistant and fire-resistant to protect occupants of a protected space from harm. The digital displays and cameras are positioned on opposing sides of the mounting frame, each camera transmitting a live video feed to the opposing display, creating the appearance of a window while protecting occupants. The digital displays may be used to display any desired information. An emergency protocol may be activated to communicate with emergency services. A plurality of laminate layers bond and encapsulate the displays and cameras to the hardened core, forming a rugged, self-contained unit with no moving parts.

The present invention relates to a door frame, particularly a door frame for a pre-hung door assembly, which is foldable to minimize storage space and to allow for enhanced logistic efficiencies. The door frame contains parallel, spaced apart, vertical jambs and a horizontal header connecting the top ends of the jambs. Each of the jambs and the horizontal header contains a front section and back section that are hingedly joined so that then can be folded on to each other. The hingedly joined front and back sections allow the door fame to be foldable to minimize space occupied during storage.

A door unit in kit form includes a partially preassembled split doorjamb assembly, a door, and extensions. The partially preassembled split doorjamb assembly includes first and second side bases substantially parallel to one another and a header base substantially perpendicular to and interconnecting the first and second side bases. The door is arranged within a space defined by the first and second side bases and the header base of the partially preassembled split doorjamb assembly so that the door, the first and second side bases, and the header base collectively establish a cavity. The first and second side extensions and a header extension are unassembled with respect to and connectable lengthwise to the first and second side bases and the header base, respectively. The extensions may be stowed within the cavity and/or stored on outer surfaces of the bases.

Examples of the present disclosure provide an overhead door panel. The overhead door panel includes a pair of parallel glass panes, a metal frame with parallel lateral stiles oriented perpendicular to the pair of parallel glass panes, a first seal system located at a first lateral stile, and a second seal system located at a second lateral stile, wherein the first seal system and the second seal system engage with at least one glass pane of the pair of parallel glass panes and a lateral stile of the parallel lateral stiles of the metal frame such that the first seal system and the second seal system are between the at least one glass pane and the lateral stile.
