Electrical fittings for suspended ceilings

A suspended ceiling grid comprising:

• a plurality of tracks arranged to form the grid;
• and
• at least one electrical appliance, clipped to a track;
• wherein the appliance includes a base having a central recess with a central aperture, the base adapted to clip onto a member of the suspended ceiling grid, and wiring, passing through the central recess and the central aperture, for connection to an electrical supply above the ceiling, the wiring being sufficiently thin to pass through the ceiling between the grid and the panels.

An electrical appliance for use with a suspended ceiling having a ceiling grid with flanges and a plurality of panels seated on the flanges, the appliance comprising:

• a lamp;
• a base attached to the lamp, the base having a central recess with a central aperture, the base including at least one U-section clip, the clip defining an aperture sized to engage a flange;
• and
• at least one wire electrically coupled to the lamp;
• wherein the wire passes through the central recess and the central aperture, and has a thickness that is substantially smaller than the thickness of a panel.

A suspended ceiling grid system comprising:

• a plurality of tracks arranged to form a grid, each track having a central web and at least one horizontal flange defining an inverted T-section, the tracks defining a plurality of spaces for accepting panels;
• a plurality of panels, each panel fitted in a space defined by surrounding tracks and seated on flanges surrounding the space, whereby a portion of the bottom face of the panel and the peripheral edge of the panel define, with the top faces of the supporting flanges and the facing faces of the webs of the surrounding tracks, a peripheral L-shaped gap around the peripheral edge of the panel between the panel and its supporting tracks;
• at least one electrical appliance including a base having a central recess with a central aperture, the appliance located below the grid and clipped to the track;
• and
• a wire, for electrically connecting the appliance to an electrical supply above the ceiling grid, the wire passing through the central recess and the central aperture.

An electrical appliance for use with a suspended ceiling having a ceiling grid with opposing flanges, and having panels seated on the opposing flanges, the electrical appliance comprising:

• a base having the shape of a flanged channel, the flanged channel defining outer flanges, the outer flanges adapted to clip onto the opposing flanges of the ceiling grid, the flanged channel further defining a central recess with a central aperture;
• a hollow stem attached to the base at the central aperture;
• and
• a lamp attached to the hollow stem;
• such that the hollow stem and the central aperture form a conduit for passage of at least one electrical wire from the lamp, through the hollow stem, through the central aperture, and into the central recess.

A suspended ceiling grid system comprising:

• a plurality of tracks arranged to form a grid, each track having a central web and at least one horizontal flange defining an inverted T-section, the tracks defining a plurality of spaces for accepting panels;
• a plurality of panels, each panel fitted in a space defined by surrounding tracks and seated on flanges surrounding the space, whereby a portion of the bottom face of the panel and the peripheral edge of the panel define, with the top faces of the supporting flanges and the facing faces of the webs of the surrounding tracks, a peripheral L-shaped gap around the peripheral edge of the panel between the panel and its supporting tracks;
• and
• at least one electrical appliance including a base in the shape of a flanged channel defining a central recess with a central aperture, the appliance located below the grid and clipped to the track;
• such that the central aperture and the central recess form a conduit for passage of at least one electrical wire from the electrical appliance through the central aperture, through the central recess, and through the L-shaped gap to an electrical supply above the ceiling grid.
