Claims9
A folding closure having a plurality of panels arranged one after the other;
- a hinge located between each pair of adjacent panels, the hinge joining the adjacent panels together along their adjacent side edges while spacing the adjacent panels slightly apart to provide a gap between them;
- a carrier member on, and extending across, the bottom of each panel;
- one or more sweeper strips slidably mounted on the carrier members to provide a sweeper extending across the bottom of the closure, each sweeper strip traversing at least several consecutive panels and passing unbroken and unsupported from one carrier member to the next across each gap between adjacent panels.
