Abstract
A basketweave-type suspension ceiling grid system is disclosed wherein the grid members are generally U-shaped providing a relatively wide face portion, oppositely extending panel support flanges, and a pair of spaced and parallel webs. The system provides a connector system in which the female part of the connector system is provided by a longitudinally extending slot substantially adjacent to the panel support flanges. Male end connector parts are proportioned to fit through the slots and lock therein to the members of the grid. The male connector part provides a generally T-shaped lanced projection which extends rearwardly and upwardly from a hinge line and is formed with raised wing portions providing stop surfaces for engaging the remote side of an associated web. A dimple formed intermediate the rings and rearwardly therefrom provides a stop surface limiting the insertion movement of the connector. The rearwardly extending stem part of the T-shaped lanced projection can be depressed to release the lock surfaces and allow disassembly of the members. In one embodiment, the connector is integrally formed on the runner end, and in another embodiment the end connector is a separat…
