An assembly for securely enclosing an opening defined by a building structure comprising a frame sized to be disposed to substantially surround the opening and engage the structure and a panel pivotally securable to the frame and sized to substantially cover the opening, the panel having a front and a back. Locking means for selectively locking the panel to the frame in a closed position and unlocking the panel so that it can be pivoted to an open position, the locking means comprising selectively an internal locking means manually operable only from the inside of the building and an external locking means manually operable from the outside of the building.

The invention relates to systems and techniques for manufacturing articles containing cellulosic material, a tackifier, and a binder, and related processes of making and using the cellulosic articles. In particularly exemplary embodiments, the manufactured articles are door skins, sometimes known as door facings, and doors made from the door skins. The article contains a lipophilic cellulosic material, a tackifier, and a binder.

A door includes a rectangular panel having a first face, a second face, and two pairs of opposing edges, in which the edges of each pair of edges are parallel and in which a first pair of edges is longer than a second pair of edges. The rectangular panel includes a layered composite material, in which a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer and that includes a material having a negative Poisson's ratio (NPR). The door includes a hinge including plates joined together by a joint, in which a first one of the plates is attached to a first one of the edges of the first pair of edges and in which a second one of the plates extends beyond the first one of the edges. The door also includes a handle opening defined through a thickness of the rectangular panel.

A composite structure for stationary and mobile flat elements, the structure including a two-dimensional infill, in particular multiple glazing or a composite panel, having first composite profiles each having an outer profile, an inner profile and one or more first separation bars connecting the outer profile and inner profile. The connection between outer profile and inner profile is shear-enabled in the longitudinal direction. The outer profile is mounted against an outer side of the peripheral zone of the infill shear-resistantly relative to the infill in the longitudinal direction in a first length portion of at most 5% of the length of the outer profile, but shear-enabledly over the remaining length. The inner profile is mounted against an inner side of a peripheral zone of the infill shear-resistantly relative to the infill in the longitudinal direction in a second length portion of at least the length of the first length portion.

Molded articles are provided. An exemplary molded article includes an inner panel portion, a main body portion, and a contoured portion extending between and interconnecting the inner panel portion and the main body portion so as to surround the inner panel portion and be surrounded by the main body portion. The contoured portion includes contoured corner segments and contoured elongated segments extending between respective pairs of the contoured corner segments. The contoured corner segments have a first maximum thickness. The contoured elongated segments have a second maximum thickness that is greater than the first maximum thickness. Related methods, assemblies, and apparatus are also provided.

A door having acoustical sound isolation properties includes a rail or stile having surfaces with a first, second and third planar portions stepped inward from and parallel to each other. Blocking layers are disposed parallel to and below one of the door surfaces, with each blocking layer having an edge with an extending flange contacting and extending along the second planar portion of the third surface of the stile or rail. The flanges of the blocking layers restrict movement of the layers toward each other. Soft acoustical material is disposed in the door interior. Flexible transition layers extend along the stile or rail third planar portions and extend over the blocking layers and the soft acoustical material to provide support against denting forces to the door.

Hollow core door apparatus for preventing the build up of pressure in a room includes an inside door skin and an outside door skin, and the door skins include openings through which air flows. A center panel is disposed between and spaced apart from the skins. The center panel has an outer perimeter defined by notches through which air flows. Tabs between the notches are used to secure the center panel to the inside and outside door skins. Air flow from the room is through the opening in the inside skin, around the outer perimeter of the panel, and outwardly from the door and room through the outside skin in a non-linear manner. The door alone with normal undercuts and margins, and with its notches and associated structural elements, achieves a Rater-measured pressure differential of equal to or less than 3 pascals with respect to the main body of the building when bedroom room doors are closed. For larger rooms with air flow greater than one hundred fifty cfm, the pressure is equal to or less than 5 pascals. Air flow is controlled by a plurality of movable panels disposed adjacent to the outer perimeter of the center panel. Sensor elements for sensing desired information and for providing output signals, including signals for actuating the movable panels, are included. The air flow outwardly through the door is at least as great as the air flow into the room, thus the door provides internal transfer of air through the door to eliminate air pressure build up in a room, and at the same time limits light, sight, and sound travel through the door.

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. The frame member may include a core; and a two-piece 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 door assembly may further include at least one adjacent panel. Also disclosed are door jamb frame members and mullion frame members.

A corner fitting for a door element, in particular for a glass door element, includes first and second fitting elements, which each include, at least sectionwise, a locating portion, which includes an intermediate layer able to contact the door element. The fitting elements delimit the restraining area, wherein a holding element is in operative connection with a connecting element, which serves for supporting the door element on a center of rotation and/or an axis. At least one exchangeable rigid distancing element is disposed between the fitting elements outside the locating portions. The distancing element forms a counter-bearing to the locating portions and the door element which can be restrained in the restraining area.

Molded articles are provided. An exemplary molded article includes an inner panel portion, a main body portion, and a contoured portion extending between and interconnecting the inner panel portion and the main body portion so as to surround the inner panel portion and be surrounded by the main body portion. The contoured portion includes contoured corner segments and contoured intermediate segments extending between respective pairs of the contoured corner segments. The contoured intermediate segments have a first maximum thickness. The contoured corner segments have a second maximum thickness. The first maximum thickness of the contoured intermediate segments is greater than the second maximum thickness of the contoured corner segments. Related methods, assemblies, and apparatus are also provided.
