ABSTRACT:
This invention concerns an arch structure. In particular, the invention relates to an arch structure comprised of at least two segments which are rotatably linked to each other via hinges or equivalent means to form a continuous bendable chain of attached segments. The segments have magnets above the rotatable or hinged link on opposed end faces, positioned to oppose magnets on confronting end faces of adjacent arch segments, with like poles facing one another, thereby creating a repulsion force. The repulsion force inhibits the arch segments from being brought together and into contact. Due to this effect, the aggregate of the arch segments define an arcuate path (convex upward), maintained by the repulsion forces of the magnets.
