A door includes a single panel folded to form a latch face and first and second main faces of the door. The door preferably further includes edge tabs folded to form upper, lower and hinge faces of the door. The panel is preferably a composite panel including an inner metal sheet, an outer metal sheet, and a plastics core material between the metal sheets.

A 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. 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.

Sensor elements for detecting aspects of the indoor environment and for providing output signals, including signals for actuating the movable panels, are included. A method of making the door follows the structural elements defined above.

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 panel for an overhead sectional door includes an exterior skin on an exterior-facing side of the panel and an interior skin on an interior-facing side of the panel that define a plenum. An insulating material is disposed in the plenum. An upper backer strut is disposed in the plenum proximate a top leading edge of the interior skin and extends across a full length of the panel. A lower backer strut is disposed in the plenum proximate a bottom leading edge of the panel and extends across a full length of the panel. The upper backer strut and the lower backer strut each include first and second strut legs extending into the plenum. The first and second strut legs are spaced from the exterior skin. Hardware is attached to the panel by fastening the hardware to one of the upper backer strut and the lower backer strut.

The present invention is directed to a door skin having an exterior surface with an woodgrain pattern formed therein, and an etched plate for use as an embossing plate or with a molded die set, for forming the woodgrain pattern in the door skin. The exterior surface has outer portions lying on a first plane, spaced grooves recessed from the plane of the outer portions, and halftone portions. The halftone portions have spaced protrusions defined by channels, wherein the channels are recessed from the plane of the outer portions.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

A flexible unitary sandwich-like panel overhead door (11) consists of two relatively thin elastic sheets (12) and (13) connected by a plurality of elongated parallel web panels (14) which have supporting rollers (16) attached. The sheet-web connections are hinged (15) so that the panel may be flexibly moved from a closed vertical position to an open overhead nearly horizontal configuration. A rectangular beam (17), attached to the elastic sheets, provides additional stability and strength to the door structure. Additional embodiments are described.

A ligature resistant flexible swinging door assembly includes a frame mount, a flexible door panel, and a pivot assembly operably connecting the door panel to the frame mount such that the door panel is pivotable in two opposite directions from a closed position to first and second opened positions. The door panel is formed from a flexible polymeric material having a modulus of elasticity between 250 and 470 ksi (1.79 and 3.24 GPa), a flexural yield strength between 5220 and 15000 psi (36 and 103 MPa), a flexural modulus between 141 and 450 ksi (0.971 to 3.10 GPa) and a flexural strain at yield between 7.00% and 7.20%. The door panel has a width of between 26 and 42 inches (66.0-106.7 cm) and a thickness of between 0.040 and 0.315 inches (1.0-8.0 mm).

Described is a garage door panel rail reinforcement device that is configured and constructed to be installed on an upper or lower rail of a tongue and groove-type garage door panel. Also, a garage door panel rail reinforcement device that is configured and constructed to be installed on an upper or lower rail of a ship lap-style garage door panel is described. Further, an adjustable garage door panel rail reinforcement device is described. In general, some implementations can be configured to fit other profiles of components forming a garage door rail disposed at a meeting point of two adjacent garage door panels.
