This inventive change is to the family of umbrellas. Instead of being a folding circular cover of nylon etc. attached to ribs from a stick, that someone would carry, or a larger folding marketing type, this umbra or penumbra, (part shade) as I will refer to it, differs as follows: The penumbra construction is based on a suspension system, built of plastic or aluminium, etc. Because of its size, (twice the span of regular umbrellas) it is of rigid frame, and has to be assembled. The covering consists of six separate equilateral triangles of material, hemmed to receive elastic chords, to be stretched from the centre post to two of the outside posts of the perimeter. The chords hold the assemblage together, while also supporting the shade panels at alternating heights to alleviate wind updraft. The covering panels can be closed, and side panels added to produce a tent structure.
