Abstract
A self-erecting tent structure having a first substantially circular member of a certain dimension and providing at least a second circular member for attachment thereto. The second circular member is attached a points along the length of the first member by constraining the first circular member with a tie forming the circle into an ellipse of a desired dimension. A second circular member is constrained also into an ellipse with the ends portions of the circle formed into a 'saddle shaped' by equally elevating the opposite ends of the longer axis of the ellipse of the second member; and aligning the 'saddle shaped' member with the convexed side upward over the first elliptical member so that the bottom arcs of the saddle touch and are congruent with the opposite sides of the shorter axis of the first elliptical member. This saddle shaped member is then attached to the first elliptical member at the points where the two members meet, which are substantially equal on opposite sides of the member.
