Abstract: A shelter comprises at least two sets of arched support ribs with the support ribs of each set being pivoted by the adjacent ends thereof upon a common locus and having one set of support ribs over spanning the other set at an angle to each other. Some of the intersections are secured together and a flexible cover is secured over the support ribs. By situating the end support ribs in a plane at an angle to the supporting surface upon which the shelter is erected, substantially triangular openings are defined which can be used for access if required.
