Lighting device (22) for a false ceiling (10) comprising a plurality of T-profiles (14) having respective longitudinal axes (A) and arranged in a square mesh grid (12), in which each T-profile (14) has a lower wall with a width (W) and in which the grid (12) has a center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, in which the lighting device (22) has an elongated parallelepiped shape with a width (W′) comparable to the width (W) of said T-profiles (14), a height (h) of less than 15 mm and a length (D′) comparable to said center distance (D) between the longitudinal axes (A) of T-profiles (14) parallel and adjacent to one another, and in which said lighting device (22) is capable of being fitted directly in contact with the lower wall of a respective T-profile (14).

Described herein is a ceiling system that includes a spring clip for mounting ceiling panels equipped with torsion springs to a ceiling support grid, the clip comprising: a body including a mounting portion defining a downwardly open receptacle configured for attachment to a ceiling grid support member; a pair of lateral flanges extending outwards from the mounting portion, at least one of the flanges including a slot configured to engage a torsion spring; a pair locking tabs disposed on the spring clip, the locking tabs configured to engage opposing sides of the grid support member.

A pass through grid connector clip for a suspended ceiling. The grid connector clip is made of two identical halves connected back-to-back by a fastener passing through a first aperture of both identical halves or other joining method. The identical halves each have a web with a first side and an opposite second side defining a height; a third side and an opposite fourth side defining a length; a louver element closer to a fourth side than the third side; a half sleeve located between the clip and the louver element and extending from the first side to the second side the in a substantially semi-circular shape; the first aperture located between the half sleeve and the clip or the half sleeve and the louver element. The halves include a clip connected to the third side and two flanges projecting in substantially the same direction from opposite sides of the web. As a result, when the halves are joined back-to-back they form a pass through sleeve.

Described herein is a method for mounting a grid hanger assembly of a ceiling system. The ceiling system, in one embodiment, includes a grid support member, ceiling panel, and grid hanger configured to support the grid support member in a suspended manner from an overhead structural support. The grid hanger includes a mounting bracket configured for attachment to the structural support and a hanger member. The hanger member is adjustable in a plurality of selectable mounting positions relative to the mounting bracket, thereby allowing the mounted height of the grid support member to be adjusted in the field. In some embodiments, the hanger member is further angularly adjustable relative to the mounting bracket to avoid installation obstacles.

A clip (3) for use in a suspension system for the vertically suspended acoustic baffles (2) and a frame element (4) for the acoustic baffle is provided in a suspended ceiling system. The clip and frame facilitate multiple connection options for a vertically suspended acoustic baffle in a single system.

A ceiling system is provided for use in a building space having a plurality of walls. The ceiling system includes a grid system that extends to at least two of the plurality of walls and separates the building space into an occupiable space below the grid system and a plenum space above the grid system; and a plurality of ceiling tiles that are supported by the grid system and, with the grid system, create a barrier between the occupiable space and the plenum space, the plurality of ceiling tiles including three different polygonal non-rectangular ceiling tiles.

An assembly for connecting a sprinkler to a branch line of a fire suppression system includes a flexible conduit having one end attached to the branch line. The opposite end is attached to the sprinkler. An adapter may be positioned between the conduit and the sprinkler, between the conduit and the branch line, or between the conduit and both the branch line and the sprinkler. The adapter contains a rotating joint which prevents torque from being applied to the conduit. The adapter between the conduit and the sprinkler is received within a bracket. The bracket also receives a cross beam for securing the sprinkler relatively to the branch line.

The present disclosure relates generally to ceiling panels, for example, suitable for use forming a ceiling surface. The present disclosure relates more particularly to a ceiling panel including a panel body and a bracket. The panel body includes an upper surface, a lower surface, a first end, a second end, a first lateral side, and a second lateral side. The bracket extends upward from the upper surface of the panel body and is offset from a center of gravity of the panel body toward the first end. The bracket includes an upper fastener configured to attach the ceiling panel to a frame element of a ceiling grid. An angle of the panel body is adjustable with respect to the attachment of the upper fastener of the bracket.

An improved connector for a main tee of a suspended ceiling grid that has multiple locking elements that increase connection tensile force properties. The connector has an end tab with a forward portion bent at a lead angle and a receiving pocket with an outwardly flared entrance that, with an opposed identical connector, cooperate to provide smooth horizontal alignment. The end portion, additionally, includes an edge profile that vertically aligns itself with the receiving pocket of the opposed connector. The receiving pocket includes a spring-like resilient wall that limits the assembly force to overcome interference with projecting lock elements. The spring-like pocket wall and shape of the lock elements contribute to an audible click signaling that a connection has been completed. One of the lock elements works with a relief groove to augment self-alignment of the connectors.

A ceiling suspension system that includes a plurality of acoustic panels that are configured to be installed or attached into openings of a grid formed by main runners and cross runners of the ceiling suspension system. The acoustic panels include a plurality of main blades that extend in the same direction as the main runners and cross blades that extend in the same direction as the cross runners. Two or more of the main blades comprise a kerf in a first lateral edge of each main blade. The kerf comprises a first slot and a second slot that form a stepped configuration.
