<p>A folding structure provided with eight rods, four (5) of which stand upright, vertically or canted, and four (1) of which cross each other diagonally and are secured to each other near their midpoints (2). The lower portion (6) of each diagonal rod is connected to the lower portion (6) of an upright rod. The upper portion of each diagonal rod (1) is connected to the upper portion of the upright rod (5) located at the corner diagonally opposite the first upright rod. In the first and second embodiments, a seat bottom comprised of flexible material (12) is supported at four corners (11) where the upper ends of the diagonal rods meet the upright rods. Arm and back supports (26, 28) of a flexible material are supported by portions of the upright rods extending upward beyond the seat level. In the third embodiment (fig. 20-22), the diagonal rods (1) extending past the joint between the upper ends of the upright rods (5) and the diagonal rods (1) form supports for a suspended flexible seat (39). In the fourth embodiment (fig. 28-30), the diagonal rods extending past the joints between the upper ends of the upright rods and the diagonal rods form supports for folding braces (41) which in turn support a folding table top (44). All of these structures can be easily collapsed to a compact linear storage configuration in which the diagonally crossed rods pivot into a position alongside one another while the upright rods assume a position alongside the diagonal rods.</p> |
