<p>Three canvas panels (2, 3, 4), each framed by a flexible wire loop, are hingedly connected to one another in a continuous sequence to form a collapsible and foldable triangular, or A-frame shelter structure. The edge (5) of one of the panels is hingedly connected to an outer (7), central portion of another panel in order to allow all the panels to conveniently fold against one another into a compact and flexible flat assembly. The construction technique is applicable to a variety of structure shapes using different types of polygonal or circular panels.</p> |
