Object:

A building that enables lighting and air-conditioning to be effectively linked with each other is configured.

Resolution means:

An air-conditioning device including a connector receiving portion is installed on a ceiling, and the air-conditioning device and a plurality of lighting fixtures disposed around the air-conditioning device are electrically connected to each other with wirings provided for the number of the plurality of lighting fixtures installed around the air-conditioning device. Further, the air-conditioning device supplies power converted into a power voltage for the lighting fixtures to the plurality of electrically connected lighting fixtures. A wiring that passes through the rear of the ceiling is taken out of an opening of a ceiling member, and is connected to the lighting fixtures, so that the lighting fixtures are installed on the ceiling. An operation unit is operated to collectively control the air-conditioning device and the plurality of lighting fixtures disposed around the air-conditioning device.

A bar hanger member is provided. The bar hanger member is for assembling with another like-member by superposition thereon to form a bar hanger for supporting recessed luminaires. The bar hanger member includes: an elongated body having a front face and a rear face; a channel extending through the body along the lengthwise axis; and first and second protrusions extending from the body aligned with the channel. The first and second protrusions are sized and shaped for slidable engagement with the channel of the like-member. When the bar hanger is assembled with the like-member, the second protrusion of the bar hanger engages in the channel of the like-member and the first protrusion of the like-member engages in the channel of the bar hanger member.

A ceiling system is provided for use in a building space. The ceiling system has an open cell grid structure and is attached to a support structure of the building via hanging hardware. The open cell grid structure is constructed of a plurality of first panels attached to the hanging hardware, a plurality of second panels attached to the plurality of first panels, and a plurality of third panels attached to the plurality of second panels. The first, second, and third panels are attached via a plurality of slots which allow secure engagement and utilize gravity to retain them in the assembled condition. Beneficially, the plurality of second panels and the plurality of third panels are free of hanging hardware.

A mounting clip and a system for mounting a vertical panel from a support member suspended from a ceiling. The mounting clip has a panel mounting section, a support member receiving portion, and a movable mounting section. The support member receiving portion extends from the panel mounting section. The movable mounting section can be rotated relative to the support member receiving portion to secure the mounting clip to the support member.

This invention relates to a suspended ceiling, comprising a metal grid structure and a plurality of drop-in ceiling panels supported by the metal grid structure. Each of the ceiling panels includes a thermal conductive metal substrate, a heat insulating coating formed on the top surface of the metal substrate, and a thermal conductive ceramic coating formed on the bottom surface of the metal substrate. The heat insulating coating is provided to prevent heat generated in a plenum space between the dropped ceiling and a actual ceiling from traveling down to the room below the dropped ceiling. And, the thermal conductive ceramic coating is provided to enhance a heat transfer capability of the metal substrate. As such, the ceiling panels can facilitate rapid cooling of an air-conditioned room.

A horizontal room partitioning device for dividing a room horizontally includes a plurality of sectioning modules. Each sectioning module comprises a housing, configured to couple to a first wall, that has an open front. A panel is coupled at a first end to a back wall of the housing. The panel is extendable from and retractable into the housing through the open front. A first fastener is coupled to a second end of the panel. A second fastener that is complementary to the first fastener is configured to couple to a second wall opposite the housing. Each of a pair of guides extends between a respective opposing end of the housing and a respective opposing terminus of the second fastener. The sectioning modules are configured for planer installation within a room, such that an upper part of the room is reversibly separable from a lower part of the room.

An aerosol dispensing system has a container assembly, an actuator assembly, and a trigger member. The container assembly has a valve assembly. The actuator assembly has an actuator housing defining a rail portion, a trigger member pivotably attached to the actuator housing, and an outlet assembly defining an outlet opening. The outlet assembly is slidably supported relative to the actuator housing by the rail portion. The trigger member engages the outlet assembly such that application of deliberate manual force on the trigger member causes pivoting movement of the trigger member relative to the actuator housing and such that pivoting movement of the trigger member relative to the actuator housing causes linear movement of the outlet assembly relative to the actuator housing. The outlet assembly engages the valve assembly such that linear movement of the outlet assembly alters the valve assembly from a closed configuration to a fully open configuration.

A suspended ceiling comprising SUSPENDED metal runners in a horizontal plane, the runners each having a horizontal flange having an effective vertical thickness, a plurality of rectangular drywall sheets aligned crosswise to the runners and screwed to the flanges with ends of the drywall sheets forming butt joints midway between adjacent runners, boards overlying butt joints and adjacent flanges, the boards being substantially stiffer than the drywall sheets, whereby the drywall sheet ends are drawn up towards an upper level of the flanges when screwed against the overlying board so that a pseudo taper is formed on the drywall sheet ends.

An acoustic housing, a light fixture, a suspended ceiling system, and a method of decreasing sound transfer from a light fixture in a suspended ceiling are disclosed. An acoustic hood for a light fixture in a suspended ceiling may include a partially enclosed space formed between a plurality of wall portions. A light fixture may include first and second layers that are coupled to one another and form a partially enclosed space. A suspended ceiling system may include the acoustic hood or light fixture. The method relates to disposing an acoustic housing spaced from the light fixture.

A ceiling system in one embodiment includes a support grid including intersecting grid support members and grid openings formed between the grid support members. A vertical baffle is positioned in a grid opening and is attached to the support grid. The baffle includes opposing front and rear faces extending between opposing lateral sides of the baffle. First and second mounting grooves formed in the baffle engage and support the baffle from the grid. In one embodiment, one of the mounting grooves is disposed in each lateral side to support the baffle from opposite sides. The baffle may further include a third mounting groove formed in the rear face which engages the support grid to help align and squarely register the baffle with respect to the grid for clean linear visuals. In one embodiment, the grid support members may have a standard T-shaped cross section.
