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
- in combination, a tighter (a) than (b) connection, and a looser (b) than (a) connection, to form a more precise 2 ft.×2 ft. opening in the assembled grid,
- wherein the position of a stop on a connector in the (a) connection and in the (b) connection determines whether the connection is tighter or looser.
The improvement in any of the above claims wherein the connections are formed by a stab-in motion of the connector.
