ABSTRACT:
A grid system for supporting panels and adaptable for use in association with a substructure, comprising a plurality of spaced, horizontally disposed main runners and cross-runners arranged perpendicular to each other. The main runners are adaptable for attachment to the substructure, and include (i) a crosspiece having a horizontally oriented surface provided with a plurality of spaced notches and (ii) a downwardly depending member terminating with a horizontally disposed flange. The cross-runners have horizontally disposed flanges arranged in a common plane with the flanges of the main runners, which support the tile panels in a common plane. The cross-runners include connecting means for insertion in the notches upon the perpendicular arrangement, and the connecting means have a horizontally oriented surface for mating with the surface of the crosspiece and disposed for overlapping engagement with the crosspiece thereby supporting the cross-runner and preventing undesired disengagement therebetween.
