Abstract
Miniature beams for easy installation onto a conventional inverted T-bar subceiling framework are disclosed. The beams comprise a flat portion or web adapted to fit snugly against the T-bar rail, the web having two hooked arms that snap over the edges of the rail and at least one element extending from the web that has a decorative element at the end of its vertical extension.

In combination, a subceiling of the type having panels supported by a suspended framework consisting essentially of (1) longitudinally extending main runner members and cross runner members, each runner member being configured as an inverted T-bar rail having a transverse pair of opposed bottom flanges extending longitudinally, (2) a plurality of miniature beams having means for fastening to the T-bar rails, each of said beams consisting essentially of:
- a flat portion having an upper surface and a bottom surface, and a width defined by two longitudinal edges;
- a first return flange disposed along one upper edge of the flat portion integral therewith and extending inwardly;
- a second return flange disposed along a second upper edge of the flat portion integral therewith and extending inwardly;
- each of said return flanges having a downward-facing surface and an inwardly facing edge;
- said return flanges adapted to hold the upper surface of said flat portion substantially flush against the longitudinally extending T-bar rails of the runner member;
- a single connecting element integral with and extending downwardly from said bottom surface of said flat portion and longitudinally along the length of said bottom surface of said flat portion;
- and a longitudinally extending decorative element attached to or integral with the downward extremity of said connecting element and comprising a pair of transversely extending elements;
- and (3) a plurality of panels extending longitudinally with said runner members, said panels adapted to rest on the return flanges of the beams.

- a single connecting element integral with and extending downwardly from said bottom surface of said flat portion and longitudinally along the length of said bottom surface of said flat portion;
- and a longitudinally extending decorative element attached to or integral with the downward extremity of said connecting element and comprising a pair of transversely extending elements;
- and (3) a plurality of panels extending longitudinally with said runner members, the bottom surface of said panels being recessed along the edges of the panels to provide longitudinally extending recessed portions, said recessed portions adapted to rest on the return flanges of the beams.
