Abstract
Abstract A collapsible room module assembly having a foldable ceiling construction is provided for transforming a large open space into a plurality of smaller rooms. Two ceiling panels are hinged to accommodate folding of one of the ceiling panels with respect to the other when it is desired to collapse the room and store the foldable ceiling. Wheels are attached to one of the ceiling panels and are adapted to engage a tubular insulation strip which is situated at the top of the wall panels of the collapsible room and which serves as a track for guiding the wheels of the foldable ceiling as it is folded or unfolded. Apparatus is provided for disengaging the wheels of the foldable ceiling from the tubular strip once the ceiling has been completely unfolded, thereby allowing the weight of the ceiling unit to compress the insulation strip so as to form an acoustic and hermetic seal between the wall panels and unfolded ceiling unit. A dividing wall which is integral with the side wall panel between each pair of rooms formed by the wall panels is provided so that the side wall panels between rooms can be opened up, thereby varying the size of the room formed.
