Abstract
A portable structure includes first and second support poles, each having one lower end for resting on a ground surface. First and second connectors attach at upper ends of the first and second support poles, respectively and two or more linking poles connect the first support pole with the second support pole via the first and second connectors. The linking poles form obtuse angles with the first and second support poles at the first and second connectors. The linking poles form an eye shape between the first and second support poles when joined with the connectors.
