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 thermally insulated door assembly with an operable panel uses a pair of structural panels, a collection of thermally-insulating fasteners, a panel hole and an operable panel. The pair of structural panels are held together by the thermally-insulating fasteners. The thermally-insulating fasteners form a rigid structure that prevents thermal conductivity between the two structural panels that make up the door assembly. This arrangement enables the door assembly to remain a rigid structure while being composed of multiple components. The panel hole traverses through the pair of structural panels to form an opening into which the operable panel is inserted. The operable panel is a panel that replaces a central section of the door assembly. This placement enables the user to remove and replace the operable panel as desired.

A door has a core that includes a first major surface having one or more first recesses, a second major surface opposite to the first major surface, and fire retardant material such as intumescent material applied to the first recesses and no more than about 20 percent by surface area of a remainder of the first major surface excluding the first recesses. A door skin includes an interior surface, an exterior surface, at least one contoured panel portion establishing a protrusion extending on the interior surface and an opposite depression extending into the exterior surface, and fire retardant material such as intumescent material applied to at least one of the protrusion or the depression and no more than about 20 percent by surface area of the remainders of the interior surface excluding the protrusion and the exterior surface excluding the depression.

The present application relates to the field of storage technology, and provides a door assembly and a storage cabinet. The door assembly includes a door body provided with a handle groove; a driving assembly; a rack hinged to the door body and provided with a cover plate assembly; and a first detecting member configured to generate a first detecting signal; where the driving assembly is adapted to drive the rack to switch between a pressing state and a resetting state based on the first detecting signal; and in the pressing state, the cover plate assembly avoids the handle groove, and in the resetting state, the cover plate assembly shields the handle groove.

Composite door systems are provided for use in a protective barrier structure. The composite door systems provide for quick assembly, safety, security, and resistance to physical impacts or threats. The composite door systems may include a shell and a core that can be factory completed or finished on site. The shell may be shipped to the assembly location of the barrier structure, and the core may be formed on site by pouring liquid fill material into a cavity of the shell, which is allowed to cure into a solid fill material. Hardware housings may be operatively coupled to the shell that are made to receive door hardware but resist the liquid full material from filling the hardware housings. The shell, core, and/or hardware housings may provide resistance to damage, such as projectiles to provide enhanced security protection to the occupants or contents of the building structure.

A sound damping door system having a door frame, a compression seal, a door slab, a bottom seal, and a concealed hinge assembly. The door frame includes male and female components adapted to engage each other in a rough door opening between first and second wall faces; and at least one isolation gasket adapted to be disposed between the male and female components. The compression seal is mounted to the door frame. The door slab includes an outer skin; an arched constrainment sheet inside the outer skin; a damping fill material inside the outer skin; and an acoustic insert inside the outer skin. The bottom seal is mounted to a bottom surface of the door slab such that the bottom seal is permitted to move relative to the door slab.

Implementations of detachable window systems may include: a main panel including one or more windows therein, the one or more windows in the main panel each having a window casing, a screen, and a window opening mechanism; an upper panel hingedly coupled to an upper side of the main panel; and a lower panel hingedly coupled to a lower side of the main panel opposing the upper side. The window opening mechanism on each of the one or more windows may be used to open the window to permit air to flow through the screen.

The disclosure relates to systems and methods for pressing a door assembly involving a scanning system operable to survey an outer surface of a door skin and identify a location of one or more recessed panel portions on the door skin, and a press operable to selectably actuate a group of actuators based on the identified location of the recessed panel portions, where the actuators drive press members onto the one or more recessed panel portions of the door skin during a pressing operation to facilitate crushing of portions of a core of the door assembly that underlie the recessed panel portion of the door skin.
