ABSTRACT:
Disclosed is a suspended ceiling support system which provides a ceiling which is essentially flush with its supporting members. The support system attaches to the lower surfaces of joists forming part of a floor and supports a plurality of ceiling tiles. The system comprises a plurality of elongated support members extending between adjacent joists, the support members being located in at least one row, at least one main tee runner extending parallel to the row of support members, at least two wishbone-shaped springs attached to the main tee runner and which each extend through an aperture in a support member such that the main tee runner can be supported in at least two positions relative to the support member, and at least two cross-tee runners extending perpendicular to the main tee runner, one end of each cross tee runner being supported on the main tee runner whereby the cross-tee runners and main tee runner are capable of supporting at least one ceiling tile. By virtue of this design, the ceiling can be lowered for insertion or removal of ceiling tiles, and raised upwardly to position the finished ceiling firmly against its supporting surfaces.
