Disclosed is a suspended ceiling system, a securing member, and process of installing a patterned suspended ceiling system. The suspended ceiling system includes a grid system having first members and second members, and at least one substrate which extends below the grid system. The at least one substrate has an exposed surface and a concealed surface, and the at least one substrate has first sides and second sides which extend between the exposed surface and the concealed surface. Securing members attach to the concealed surface proximate the first sides, and the securing members have grid engagement members which secure the at least one substrate to the grid system. The securing members cooperate with the first members and the second members of the grid system to properly position the substrate and the spacing between adjacent at least one substrates is controlled.

A support member for a suspended drywall ceiling grid system includes a central web formed of two layers of sheet metal having first and second ends, a reinforcement bulb extending from an upper portion of the central web between the first and second ends, opposed flanges extending from a lower portion of the central web between the first and second ends, first and second end connectors integral with the central web and extending from the first and second ends of the central web, respectively, past the flanges, each of the opposed flanges having an upper surface and a knurled lower surface between the central web and a rolled edge portion, and each rolled edge portion having an initial region tilted downward and outward and extending into a curved region, wherein the curved region is rolled upward and inward and terminates in an outer edge toward the initial region.

A ceiling grid system as part of a suspended ceiling having a plurality of ceiling panels includes main runners and cross-runners oriented transverse to each other and forming a two-dimensional array having openings, each opening defining a position within the suspended ceiling in which a ceiling panel is disposed, the main runners and the cross-runners being configured to attach to each other and to be fixed in the horizontal plane in the physical space, each one of a plurality of panel support members is connected with a main runner or a cross-runner and is configured to support one of the ceiling panels, each panel support member is movable in a rotatable or linear manner with respect to the main runner or the cross-runner to facilitate the installation or removal of one of the ceiling panel with respect to its predetermined position within the suspended ceiling.

A ceiling system for a clean room, a clean room ceiling and a method for constructing a ceiling for a clean room are provided. T-shaped beams support the ceiling from a building structure. Channels support composite panels on the bottom side of the T-shaped beams. Each of the channels is attached to the top side of a composite panel and each engages a first or second leg of a T-shaped beam. The channels may be Z-channels.

A system and method for creating a trompe-l'oeil skylight in a ceiling where a light emitting image of the sky is provided in a structure configured to emulate a skylight frame, including an embodiment of a unified non-rectangular sky image area in a substantially rectangular fixture which mount as a single unit into a substantially rectangular hole in a ceiling.

A method of creating a sculpted decorative ceiling with lighting fixtures in a suspended ceiling grid utilizing ceiling components constructed with structural side elements and a floor, forming a cavity that extends downward three to five inches. Each individual component has a perimeter installation flange enabling it to be installed into a new or existing ceiling grid system cell. The said components esthetic contours and functional structural side elements, as well as the size of the perimeter installation flange create space(s) between installed components, throughout an entire ceiling arrangement of said components or in specific areas of arrangements of said components, for luminesce channel(s) in which may be positioned one or more lighting fixtures, or combinations of lighting fixtures, attached to the room facing surfaces of the cross tee or main runner flanges that comprise the ceiling grid structural assembly. Components may have floor perimeter shapes approximately equal in area to the entire ceiling grid cell, or they may have floors perimeter shapes occupying only part of the ceiling grid cell with a filler section at right angles to the structural side elements of the component that extend co-planer to the perimeter installation flange. Ceiling components can come in a variety of floor profile shapes allowing the construction of a wide variety of arrangements in the suspended ceiling grid. The side panels and the floor can be created with a wide variety of decorative surfaces.

A folded architectural panel folded from a flat sheet, the panel having opposite longitudinal ends extending in a width direction, opposite lateral sides extending in a length direction and a depth perpendicular to the width and length directions. The panel includes a first downward fold adjacent one longitudinal end, extending in the width direction, and having opposite fold ends at the respective lateral sides of the panel; a second downward fold adjacent the other longitudinal end, extending in the width direction, and having opposite fold ends at the respective lateral sides of the panel; and a central upward fold at a central portion of the panel between the first and second downward folds; the first downward fold, the second downward fold and the central upward fold enable contraction of the opposite end folds towards each other to cause folding of the first and second end folds and an increase in the depth of the panel at the central portion. The panel further includes two pairs of respective side upward folds extending from the four opposite fold ends of the first and second end folds to the central upward fold such that, with contraction of the opposite end folds towards each other, a respective section of each respective lateral side between two respective fold ends contracts inwardly towards the opposite lateral side and a respective sidewall is formed on each respective lateral side of the panel extending from the respective pair of side upward folds in the depth direction.

Ceiling tiles for drop ceilings are disclosed. The ceiling tiles have a main portion that is sized and adapted to fit within a grid of the drop ceiling, and a baffle that hangs down from the main portion. A sheet of tile material may have a plurality of fold lines defined in it that allow the sheet to fold in such a way as to define the main portion and the baffle. In the flat configuration, the sheet of tile material may have the dimensions of a standard drop ceiling tile; in the folded configuration, the ceiling tiles may also have standard ceiling-tile dimensions. A single ceiling tile may have two or more baffles, and those baffles may be staggered in position with respect to one another.

A lighted tile for false panel, including a frame having a bottom and sides that extend projecting from the bottom, a backlighting system having a series of lights attached to the bottom, and a stretched flexible sheet that extends between the sides facing the lights. The lights are light-emitting diodes, and the sheet is secured to the sides of the frame.
