Abstract The supporting grid (e.g., main and cross inverted tees) of a suspended ceiling also supports ventilation air-distributing apparatus including an air flow spreader. This apparatus comprises a lower air flow channel section formed of two extruded metal bars having vertical webs with hooks on the outside of the web defining ways into which the wings of a bracket project to hold the spaced bars in a channel assembly. A clip integral with the bracket hooks over the top of a grid tee and has gripper conformations to mate with a clip on the opposite side of the tee to align channels. The air from the duct discharges out through the opening between the webs and a spreader directs the air generally outwardly, as well as downwardly. In one aspect of the invention, special brackets are provided to support the air flow spreader at its proper position.
In an air-distributing unit adapted to fit into and be supported by the tees of a suspended ceiling tee grid system, in combination, an air spreader comprising an elongated horizontal plate having a median vertical divider extending the length thereof and a pair of flanges extending outwardly from the divider in spaced relation to the plate to form with the plate a way on each side of the divider, and brackets for suppOrting said spreader in the unit, each said bracket comprising a vertical back portion dimensioned to fit between unit and grid structural elements in the assembled and mounted unit whereby to prevent vertical and lateral movement of said bracket and a pair of spaced horizontal prongs adapted to be received respectively in said ways and defining a median slot for slidingly receiving said divider therein, said slot extending to said back of said bracket whereby said bracket may be inserted into said ways at the end of said spreader to such an extent that the over-all length of the resulting sub-assembly is increased by only the thickness of said backs of said brackets.
