Abstract:
A rectangular panel for a suspended ceiling, the panel having a suspension spring with two divergent arms at each of two opposed panel edges mounted on a rear side of the panel, each spring being mounted on the panel in an arrangement permitting the arms to lie parallel to a front face of a panel, project rearwardly perpendicular to the front face and to lie outside of the panel parallel to the front face, the spring mounting arrangement enabling the spring to be maintained in the rearward orientation by a force developed by the spring with its arms confined and locator elements for registering the panel with grid members of the ceiling.
