Abstract: An expandable structure adapted to convert from a collapsed position to an expanded position, wherein a plurality of parallel rods are mounted to pivotally interconnected links, each of which has a plurality of bores asymmetrically spaced from one another. The structure in its collapsed position is generally flat and can be conveniently stored. The structure can be expanded into an arch-shaped structure. The structure can be used as a portable drying rack, or may be used in other product applications.
