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. |

DETAILED DESCRIPTION In accordance with my invention, there is provided a surface mounted grid system for supporting an array of tile panels and adaptable for use in association with a substructure, such as a wood joist or other suitable framing member, or an existing ceiling.
Although the grid system is described herein with particular emphasis on a system to support ceiling tile, it should be understood that the grid system can support any panel other than ceiling panels, or can be used on any substructure such as a wall.
Broadly, the grid system of my invention comprises a plurality of spaced, horizontally disposed main runners and cross-runners, which are arranged substantially perpendicular to each other to form a rectangular pattern.
The main runners, which are adaptable for attachment to the substructure, comprises a crosspiece having a horizontally oriented surface provided with a plurality of spaced notches and a downwardly depending member terminating with a horizontally disposed flange.
The cross-runners are arranged substantially perpendicular to the main runners, and have a horizontally oriented flange disposed in a common plane with the flange of the main runners.
Thus, the transverse terminal edge of the flange of the cross-runner abuts the longitudinal terminal edge of the flange of the main runner.
In this manner, the flanges of the main runners and the flanges of the cross-runners support the tile panels in a common plane.
The crosspiece may be attached to the substructure, as with screws or staples at spaced intervals; or where desired, the main runner may include a base or facia for attachment to the substructure, and the crosspiece depends laterally from the fascia and is spaced therefrom and disposed between the facia and the flange.
The cross-runner includes connecting means for insertion into or through the notches of the crosspiece upon the perpendicular arrangement of the runners.
The connecting means includes a horizontally oriented surface for mating with the surface of the crosspiece, and is disposed for overlapping engagement with the crosspiece thereby supporting the cross-runner and preventing undesired disengagement between main runner and the cross-runner
