Abstract:
Architectural structures composed of a plurality of continuously curved undulated surface elements bound by continuously curved undulated edges and formed by suitable means from a relatively rigid sheet material, whereinsaid surface elements are composed of a set of convexly curved surface segments alternating with a set of concavely curved surface segments in a smooth wave-like manner, and said edges are composed of a set of convex edge segments alternating with a set of concave edge segments in a smooth wave-like manner, one said convexly curved surface segment of one said surface element meets one said concavely curved surface segment of adjacent said surface element at said convex edge segment at a constant angle, and said concavely curved surface segment of one said surface element meets said convexly curved surface segment of adjacent said surface element at said concave edge segment at said constant angle, wherein said edge is the line of intersection between a pair of singly-curved surfaces of selected size and which intersect each other at said angle, and wherein successive said angles are selected from the group comprising: convex angles only, a combination of convex and concave angles, a combination of a first set of convex angles alternating with a second set of concave angles, said surface elements and said edges correspond to a 2-dimensional pattern comprising a plurality of plane areas and a plurality of lines, wherein each said plane area is bound by a pair of said lines on either side of said plane area, and each said plane area corresponds to each said surface element and each said line corresponds to each said edge, and wherein said lines are continuously curved and undulating 2-dimensional waves consisting of alternating convex and concave curved line segments, wherein each said curved line segment is defined by the development of a portion of said edge in 2-dimensions.
