ABSTRACT:
An erectable tent structure is formed by a flexible roof covering that includes a central portion and a plurality of ridge portions that have inclined slopes and that extend along ridgelines radially outwardly and upwardly from the central portion to terminate in peaks located at the periphery of the roof covering. the slopes thus form valley portions between the ridgelines, and the valley portions have valley floors that slope radially outwardly and downwardly from the central portion. A support pole supports the roof covering at reach peak, and anchor structures secure the flexible covering to the support surface in a manner that a ridge tension force is applied upwardly and outwardly along the ridgelines and a valley tension force is applied downwardly and outwardly along the valley floors. The ridge and valley portions may be formed by joined panels so that there is a primary seam along each ridgeline and a secondary seam along each valley floor. The anchor structure preferably is a triangular anchor section joined to the flexible roof covering at the periphery between each mouth of the valley portions so as to span a respective peak. The vertex of the anchor panel is securable, to the support surface.
