ABSTRACT A self erecting portable structure is provided which comprises a single rod or wire joined at its ends by a single connector to form an of endless loop structure comprising at least a first lower loop means and a second upper loop means. A first fabric means having sleeves at each end is provided in a transverse position such that one portion of the first lower loop means and another portion of the second upper loop means is contained in the sleeve at one end of the first fabric means and such that still another portion of the first lower loop means and of the second upper loop means is contained in the sleeve at the other end of the first fabric means. Elastic tension in the first lower loop means and the second upper loop means pulls the first fabric means taut to form a first lower surface of the structure. A second fabric means having sleeves at each end is provided in a longitudinal position such that one portion of the second upper loop means is contained in the sleeve at one end of the second fabric means and such that another portion of the second upper loop means is contained in the sleeve at the other end of the fabric means. Elastic tension in the second upper loop means pulls the second fabric means taut to form a second upper surface of the structure which is separate from the first lower surface so that an interior structure space is created which can be accessed from all sides of the structure. Further, the interior structure space is created without the need for external stakes, pegs or ropes and without the need for internal poles or supports. Because of the elastic nature and the endless loop structure formed by the single rod or wire joined at its ends by a single connector, the first lower loop means and the second upper loop means together with the accompanying fabric means can be readily folded in upon themselves to form four loops of smaller diameter. The elastic energy of this folded structure is easily contained by strap and a zippered cover so that the complete structure is portable and easily stored in a closet or the trunk of an automobile. When the folded structure is removed from its storage cover, the stored elastic energy allows the structure to "pop up" into its final configuration with no further action from the user, thus providing the self erecting feature which makes the structure so convenient to use. The present invention can be employed in a wide variety of forms by changing the size and shape of the first and the second fabric means and of their sleeves. Thus, the present invention can take the form of a completely closed camping tent with screened doors and windows as required or the form of an open ended sun screen or beach shelter which can be accessed from the front and sides without sacrificing the features of being self erecting and highly portable.
