Abstract
A collapsible, readily erectable shelter structure in the form of a pyramid having a plurality of fabric panels draped over and connected to a plurality of rigid columns. Each column is hinged at its top to a top plate and extends downwardly and outwardly to form the frame of the pyramidical structure. Each column is attached to a foot plate which rests on the ground. A central cable hangs down from the top plate and is adapted to be cinched to an item, such as a vehicle, that is being protected by the shelter. The central member is thereby placed under tension and the side columns are placed under compression. A plurality of tapes or webs or cables sewn to the panels are connected between adjacent side columns. When the structure is loaded, as by wind or snow, the foot plates tend to move outward and the tapes are placed under tension. The tapes resist the outward movement of the columns. The tapes are sewn along a catenary line and distribute the resisting force evenly across the fabric panel to which they are sewn.
