    Abstract: A rollaway opening closure and more particularly a fabric opening closure adapted to be stored in a reeled or rolled position and to be unrolled from the reel to close the opening. The apparatus includes a roller, a drawbar, a sheet of fabric and at least one pivoted bar link. The axis of the roller, the drawbar and the pivot of the bar link are maintained parallel as the fabric is unrolled from the roller. The drawbar and the bar link are structurally attached. The fabric is attached to the roller and the drawbar but unattached to other elements of the apparatus. A rotational biasing means biases the fabric into rolled position on the roller and causes the fabric to be maintained taught when unrolled and in closing position at an taught when unrolled and in closing position at an opening.
