This disclosure relates to an assembly that is configured to be installed or integrated into a suspended grid ceiling.

A mounting assembly is provided for quick and easy attachment to engineered joists. The mounting assembly includes a brace assembly and a mounting bracket. The mounting assembly may also include an electrical box. The brace assembly is an adjustable member that extends between flanges of engineered ceiling joists. The brace assembly has two low profile end caps that can engage the flanges of engineered ceiling joists and apply a force against the flanges when tightened. The mounting bracket is connected to a hanger body of the brace assembly by a snap fit and the electrical box is attached to the mounting bracket.

The present disclosure relates generally to lighting elements, for example, suitable for use illuminating a ceiling. The present disclosure relates more particularly to an illuminated acoustic ceiling element including an acoustic substrate having an upper face and a lower face, an air permeable layer disposed under the lower face of the acoustic substrate and spaced from the acoustic substrate, and a light source supported by the acoustic substrate and configured to emit light through the air permeable layer.

Improved support structures and systems are disclosed for installing tablet devices, display screens, flat screen monitors, or medical devices within a wide variety of environments. A core arm extends from a rear end, toward a front end, in which the rear end is configured to be pivotably mounted either directly to a mount structure, or to an extension arm that in turn is mounted to a mount structure. The front end is configured to be pivotably mounted to a front-end panel mount structure. The structures and systems can be configured for light or heavy configurations, with or without the use of an extension arm, and can provide fully concealed cable routing, in which one or more cables are readily accessible, via snap fit covers, for easy installation and maintenance, which can provide a clean structure that can readily be serviced and cleaned as desired.

A baffle tile has a tile and a baffle. The tile is sized and shaped to be placed in a drop ceiling grid, and has a slot through its thickness. The body of the baffle is inserted into the slot in the tile so that the baffle hangs down from the tile. A pair of folding flaps are defined in an upper extent of the baffle by respective fold lines. The folding flaps are folded outwardly and down, such that they abut the upper surface of the tile. Folded down, the folding flaps define a locking slot. A locking member with features complementary to the locking slot is inserted into the locking slot to lock the folding flaps into position. The baffle itself may have additional fold lines so that it can be folded into its usable configuration from a flat sheet of material, without adhesives or fasteners.

A sound isolation assembly comprising: a center ferrule; a top grommet isolator; a bottom grommet isolator; a spring; and a furring channel engagement portion. The sound isolation assembly is configured to engage with a structure and a furring channel, which itself is connected to a ceiling panel, such that the noise passing from one floor to the other is lessened as compared to a control system that does not use the sound isolation assembly. The spring may be steel and the grommet isolators may be rubber or the like, and the combination of the steel spring and grommet isolators reduces noise.

A mounting profile for lighting system of suspended ceiling, which comprises a comprehensive triple-section aluminium profile, where repositionable wireless luminaires fitted with magnets can be used on the mounting profile and comprises devices for fastening stretch ceiling material as well as other types of suspended ceiling materials thereto.

In a suspended ceiling a housing is provided including a light located within an interior chamber having a lower opening. The housing includes lateral sides with slots therein which can receive fasteners coupled to ends of other T-bars. Ends of the housing can include fasteners, such as tabs or clips, which attach ends of the housing to adjacent supports, such as other T-bars within the suspended ceiling. In one embodiment, the housing has a constant cross-sectional form. The cross-sectional form can include lateral sides defined by lateral cross-tees with a vertical spine and lateral rest shelf upon which an edge of the ceiling tile can be supported. A central cross-tee can optionally be provided extending down from upper portions of the housing and between diagonal spans on upper lateral portions of the housing. One or more diffusers span the lower opening of the housing.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.
