ABSTRACT:
An improved roll-up closure utilizing a flexible cover or curtain selected from a material suitable to effect the type of closure sought. The cover is at least as wide as the portal to be covered and is typically longer than the portal. Each lateral margin of the cover has a strip of hook and loop fastener material affixed thereto, and a complementary strip is affixed to the lateral margins of the structure defining the portal. A first end of the cover is rigidly affixed across a first margin of the portal. The opposite end of the cover is upturned and connected to a driven take-up roller mounted to the first margin of the portal. An elongated transverse rod is supported within the upturned end of the cover. Activation of the driven roller lengthens or shortens the effective length of the cover and moves the rod therewith. As the driven roller is activated, the mating hook and loop fasteners are positioned to seal and unseal the cover to the lateral margins of the portal. The rod can either have sufficient weight to maintain tension on the cover such that the cover forms an adequate seal with the lateral margins of the portal, or in the alternative, a spring assembly or a second driven roller can be mounted to a second margin of the portal opposite the first margin to maintain tension on the cover.
