Conversion ceiling pan and system

Abstract

The conversion ceiling system disclosed may be installed immediately under a pre-existing ceiling without dismantling or removing the pre-existing ceiling. The conversion ceiling system includes pans which are adapted to cooperate with conventional inverted T-beams which, if pre-existing, support the pre-existing ceiling panels. The T-beams support the conversion pans in a side-by-side array to form a new ceiling surface. Each of the conversion pans includes a horizontally extending plate having a specially formed upwardly turned peripheral rim. At least two portions of the rim include laterally projecting tabs for engaging the flanges of T-beams and at least one of the tabs has an upstanding stop to limit the horizontal movement of the pan. The ceiling assembly may include a number of resilient clips securing the upstanding stops on the rims of the pans to the T-beams. Alternately, the pre-existing ceiling tiles may engage the stop to prevent horizontal movement of the pans. Filler pieces mask the T-beams in the proximity of light fixtures, ventilation ducts, walls and the like, giving the ceiling a continuous one-piece appearance. The conversion pans may be made of metal or other material, and various decorative coatings including mirror-like finishes may be applied to the exposed portion of the pans.
