Improvements to the subject of main Patent No. 554391, submitted on 25 April 1986, relating to a sequential- unfolding structure

摘要

The structure comprises parallel frames (ribs) which are consecutively linked by foldable elements, formed by rigid panels, articulated together and to two consecutive frames. The panels include resistant elements and they are impelled in synchronization towards their deployed position. There are automatic interlocking elements. The resistant elements of all the panels of the foldable elements define identical geometry, in the form of Vs. The Vs of the panels of each foldable element are arranged with respect to one another in a symmetrical position, articulated together via the vertexes and to the frames via the ends of their sides. <IMAGE>
