Abstract
In a ceiling grid for a suspended ceiling having 2 ft.×2 ft. openings that support panels, a connection in the grid between a main beam and 4 ft. cross beam is made tighter than a connection in the grid between a 2 ft. cross beam and a 4 ft. cross beam. Both connections use the same connector, but with a different stop position on the connector.
Claims4
In a group of main beams, 4 ft. cross beams, and 2 ft. cross beams, capable of being assembled in the field into a ceiling grid forming 2 ft. by 2 ft. square openings, the assembled grid having:
- (a) connections between a main beam and two 4 ft. cross beams, and
- (b) connections between a 4 ft. cross beam and two 2 ft. cross beams;
- wherein both connections in (a) and (b) are made with connectors of the same design;
- the improvement comprising means for making the connections of (a) tighter than the connections of (b).
The improvement in any of the above claims wherein the connections are formed by a stab-in motion of the connector.
