<p>The cover (19) is supported by a frame consisting of a series of arches (2) able to move on wheels (13) at the ends of their legs (3) or on sliders and rails. Each arch is connected to the neighboring one by pairs of hinged bars (5) linked to handles (4) between the arches. By pulling on the handles the arches are drawn together, retracting the cover so it takes up less space in a storage area.</p> |
