The has been withstand reasonable winds through the use two base supports, lower portion, arm and series vertical risers. risers in combination allow for easily expand height consistent engineering design standards when operation then compact it storage. supports are not only necessary structural stability but also open close about thus providing additional compactness. flexible hinges so that they may store flat rectangular shape rotated an position. This accomplished by linkage connecting riser supports.
