Abstract
A ceiling panel system for suspending a new and improverd ceiling panel from an assembly of inverted T-beam support members. The support members are suspended in a horizontal plane to form a desired grid pattern for supporting a plurality of ceiling panels to form a continuous ceiling. The T-beam support members comprise a vertical center leg having a pair of opposite horizontal arms, and a pair of opposite ribs projecting from the vertical center leg. The ceiling panel include a main body portion and integral resilient side walls. The side walls extend at an angle from body portion, and are adapted for captured engagement between the horizontal arms and ribs of the T-beam support members to resist removal of the panel from the support members. Each of the side walls includes a top edge spaced from said body portion having one or more slits extending transversely from the top edge toward the main body portion, to prevent the removal of the panel from captured engagement in the support members. The side walls of the ceiling panel additionally include first and second side edges which intersect the top edge, thus defining a ceiling panel with no closed corners for ease of manufacture, and a sixteen sided polygonal form in a top plan view.
