A suspension ceiling system is disclosed which includes main tee members and cross tee members which can be assembled in a variety of relationships. The main tee members are provided with similar first end connections at each end and the cross tee members are provided with similar second end connectors at each end. The main tee and cross tee members can be end connected to produce main runs consisting of alternate main tee members and cross tee members. The cross tees can also be assembled through openings provided in the webs of both types of members to produce cross runs consisting solely of cross tee members. In the illustrated embodiment the second end connectors of the cross tees can be connected in three ways. They can be connected to first end connectors of the main tees, connected through a cross tee opening without a similar second end connector extending from the other side and can be connected to a second end connector extending in the opposite direction through the same cross tee opening. The length of the main tees exceeds the grid module length by one face flange width and the length of the cross tees is less than the grid module length by one face flange width. The versatility of assembly permits the system to be marketed in packages consisting of a first predetermined number of cross tees and a second predetermined number of main tees for installation in areas or rooms having substantially different shapes. The illustrated embodiment also includes novel and improved panel locking means for holding panels against the face flanges of assembled grid systems.

Suspension ceiling system

A suspension ceiling system having an improved connecting system comprising a pair of similar ends on crossbeam connectors which are received through a single slot opening in a main beam in side-by-side relationship by a straight- in movement. Projections the crossbeam connectors interlock when fully engaged and prevent axial movement in either direction. A tab on each connector holds the first-inserted end in place prior to the insertion of the second connector.
