Abstract:
A ceiling grid structure comprisinga lower set of intersecting horizontal panel first supports for receiving ceiling panels and thereby providing a first ceiling area at a first elevation; an upper set of intersecting horizontal panel second supports for receiving ceiling panels and thereby providing a second ceiling area at a second elevation higher than the first elevation; at least one of the sets being suspended from an overlying member; and a transition zone between the upper and lower sets of horizontal panel supports comprising a series of panel third supports inclined between the upper and lower sets of intersecting horizontal panel supports for receiving inclined ceiling panels; first connectors securing upper ends of the third supports to the upper horizontal panel supports, the first connectors comprising clips having at least a first channel receiving the first support and a tab adjacent the first channel crimped onto the first support and thereby attaching the first support to the clips for supporting the third support from the first support and a second channel receiving the third support and at least one tab adjacent the second channel crimped onto the third support and thereby attaching the third support to the clip, the first connectors being free of connection to the overlying member except through the supports; and second connectors on lower ends of the third supports supporting the third supports on the lower horizontal panel supports, the second connectors comprising clips having a third channel and at least one tab adjacent the third channel crimped onto the third support, the second connectors being free of connection to the overlying member except through the supports, the third supports being inclined at a predetermined angle to the horizontal and the first and second connectors are bent to accommodate the angle.
