The present invention relates to variable optical transmission windows and window panels which are used for architectural applications, particularly in building entryway systems. This disclosure is directed to the use and powering of such panels in door and windows that, in part, physically open by manual or automatic sliding, tilting, pushing or rotating about the hinges, unless specifically mentioned otherwise. The doors may also have other electronic devices which provided added user functionality.

A system, device, assembly and methods for a frame assembly, including a connector as shown and described. The assembly may be a door frame assembly and may, by way of example, be a door jamb and/or a door mullion including a connector. A connector may provide stability to the assembly.

A door assembly and a frame member for a door assembly. 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 pair of side jambs. The invention may also be considered a frame member including a storage compartment. The frame member may include a core; and a top piece adjoining the core to form a structural member. The core and the top piece may be a composite of cellulosic material and at least one other material. The top piece may be a two-piece top piece and may include hollow cavities. Also disclosed are door jamb frame members and mullion frame members.

A mullion includes a body including a first co-extruded portion and a second co-extruded portion adjacent to the first co-extruded portion. The second co-extruded portion has a lower density than the first co-extruded portion. In some implementations, the mullion includes a body having a rear section and a pair of opposing lateral sections adjoining either side of the rear section. The lateral sections can each include two or more walls spaced from one another in a lateral direction.

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 door sill has a substrate having a recessed upward open channel formed therein, an extruded aluminum deck that at least partially receives the substrate, at least one threshold cap, an interior face cap that covers a portion of the substrate, and a lock key. A first portion of the threshold cap is coupled to the extruded aluminum deck. A second portion of the threshold cap is positioned in the recessed upward open channel adjacent a portion of the interior face cap. A portion of the lock key is press fitted intermediate the second portion of the threshold cap and the portion of the interior face cap. A seal is formed between the second portion of the threshold cap and the interior face cap. The seal is positioned proximate the inside wall of the upward open channel formed in the substrate above the bottom surface of the upward open channel.

The invention features a refrigerator cabinet door frame. The frame includes a thermally conductive outer frame, a thermally insulating inner frame member, and a sealing plate. The outer frame member includes a forward end having an outer surface that is disposed outside of a refrigerated cabinet with the frame mounted, and a rearward end defining a joint. The inner frame member includes a first end retained in the joint, and a second end. The sealing plate includes a first edge coupled to the outer frame member at the rearward end, forward of the joint, a second edge supported by the second end of the inner frame member, and a thermally conductive sealing surface. The first edge of the sealing plate is coupled to the outer frame member such that the sealing surface and the outer surface of the outer frame member together form a continuous heat transfer path.
