Abstract
Abstract A coilable closure device to open or close a door opening. The device includes a frame, a guide means, a vertical storage chamber and a single sheet of plastic vertically coilable upon itself within the storage chamber without the use of a post for storage when not in use. Whenever the door opening is to be closed the sheet is slid in the guide means across the frame to close the door opening. Vertical rods are embedded in the plastic sheet if extra stiffness or rigidity is desired. The guide means are either fixed or pivotal and the top of the plastic sheet can be horizontal or slanted.
