ABSTRACT:
A frameless self-supporting articulated dome is constructed in two opposing halves that overlap at the domes meridian to form a sealed hemispherically shaped closure when the dome is in a closed position. The dome includes a plurality of overlapping flat and flexible fins which are progressively sized and rotatably pinned at their ends along a common horizontal axis whereby said fins are in a stacking relation on opposing sides of the horizontal axis when the dome is in an open position. The dome further includes measured lengths of flexible cord fastened to the center trailing edge of each fin in series for holding the plurality of fins in their relative positions when the dome is in a closed position and further additional lengths of the same flexible cord are fastened to the center leading edges of the top most fins of each half of the dome for manually opening and closing the dome.
