The disclosure relates to support members for ceiling systems, such as those that can be formed into an interconnected grid to be suspended from a ceiling and support ceiling tiles. One aspect of the disclosure is a linearly-extending support member for a ceiling tile. The support member has a cross-sectional shape that includes a substantially vertical central web with a top end and a bottom end; at least one flange extending substantially horizontally from the bottom end of the web, the flange having an upper surface and a lower surface; and a bulb extending from the top end of the web, the bulb having a first side and a second side with a cavity therebetween, the bulb having an upper portion and a lower portion adjacent the top end of the web, wherein the entire lower portion of the bulb is narrower than the upper portion of the bulb and wider than the central web, the bulb comprising a series of spaced apertures formed therein through both the first side and the second side of the bulb, each aperture being disposed at least partially in the lower portion of the bulb, each aperture having an upper portion and a lower portion, wherein the upper portion of the aperture is rounded.

The present invention relates to a suspended ceiling hanger clip and a suspended ceiling formed using the hanger clip. The suspended ceiling hanger clip has a longitudinally extending base having a first end and a second end and a pair of generally parallel co-extensive flanges extending downwardly from the base. At least one projection in each flange is formed with a ramp surface. An aperture is formed in the base for receiving an upper end of the elongate suspension rod therein. The suspension rod has a longitudinal axis extending along a length between spaced apart upper and lower ends, with the lower end having an attachment means. The upper end of the suspension rod extends through and is fixedly retained from removal from the aperture in the base of the hanger clip.

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.

A low profile beam. This beam has a web with flanges attached to the bottom and a bulb attached to the top. The bulb is an inverted triangle connected to one edge of the web, with flanges projecting from the opposite edge of the web. The top face of the bulb is scored. In addition, the angled faces of the bulb and the flanges may be scored. The beam may be further incorporated into a ceiling system.

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.

The disclosure relates to support members for ceiling systems, such as those that can be formed into an interconnected grid to be suspended from a ceiling and support ceiling tiles. One aspect of the disclosure is a linearly-extending support member for a ceiling tile. The support member has a cross-sectional shape that includes a substantially vertical central web with a top end and a bottom end; at least one flange extending substantially horizontally from the bottom end of the web, the flange having an upper surface and a lower surface; and a bulb extending from the top end of the web, the bulb having a first side and a second side with a cavity therebetween, the bulb having an upper portion and a lower portion adjacent the top end of the web, wherein the entire lower portion of the bulb is narrower than the upper portion of the bulb and wider than the central web, the bulb comprising a series of spaced apertures formed therein through both the first side and the second side of the bulb, each aperture being disposed at least partially in the lower portion of the bulb, each aperture having an upper portion and a lower portion, wherein the upper portion of the aperture is rounded.

Described herein is a 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 embodiment, the hanger member is further angularly adjustable relative to the mounting bracket to avoid installation obstacles. Locking elements are provided to secure the hanger member in the selected mounting position. In one embodiment, the grid support member may have a T-shaped cross section.

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 fastening device for fastening lighting devices to T-shaped profiles of a false ceiling comprises a base wall on which the lighting device may be fastened. The fastening device also comprises two longitudinal side walls rigidly connected along the longitudinal sides of the base wall and a plurality of fastening elements arranged along the longitudinal sides of the base wall, wherein the fastening elements can be folded in the direction of the base wall, to engage the fastening device with the T-shaped profile. The fastening device also comprises at least two spacer elements arranged between the base wall and a respective longitudinal side wall to provide a gap between the side walls and the base wall. This gap provides a passage for the electrical connections between the lighting device and a power supply source located above the false ceiling.

A fastening device for fastening lighting devices to T-shaped profiles of a false ceiling. The fastening device may include a shaped flat body of electrically insulating material having conductive tracks embedded therein. The conductive tracks may have first ends and second ends that protrude from opposite ends of the flat body. The conductive tracks may be configured for establishing an electrical connection between a lighting device and a power supply source located above the false ceiling.
