ABSTRACT:
A plurality of small segments stowed in a compact stack are assembled, essentially automatically, into a large construction surface, such as a flat or parabolic reflector. A stowable portable construction surface of the kind having a plurality of surface segments of essentially identical configuration stacked along a common axis in overlying spaced relationship for storage in minimum space and assembleable into a side by side to extend over a wide are approximately equal to the sum of the areas of said segments means is improved by including a translational hinge means, either "step-up" or "step-down" in vertical translation, said hinge means connecting said segment means together serially and responsive to pivotal movement of one of said segment means relative to an attached other of said segment means for causing at least one edge of said moving segment means to move in vertical position from a position spaced from and coaxial with said hingedly attached other segment means to side by side relationship with said attached other segment means.
