Abstract
Ceiling panels are supported by parallel members. On one side each member has a flange extending into a slot in each adjacent panel and springs resisting motion of the panels towards the member. On the other side each member has a flange extending into a slot in each adjacent panel. Each panel is supported by two members and is movable against the action of the associated spring of one member in order to release the panel from the other member.
