ABSTRACT:
An openable closure, for example for entry to a building structure, has a plurality of arched frames pivotally mounted on the ground at each end, with fabric panels extending between frames. The first or outermost frame extends outwardly close to the ground, the next frame inclined upwardly at an intermediate position. The ground attachment positions of the first frame are positioned forward of and outward of the attachment positions of the next frame, with the first frame being longer than the next frame. The first frame can pivot up and over the next frame, with the fabric panel passing over the next frame. A similar arrangement can be provided for the next frame relative to a further frame, if provided.
