In the embodiment of Fig. 1A, a spiral staircase is formed by plates 65 extending in from cylindrical segments 61 which are released from their telescoped, nested position by raising cover 52, thereby allowing a rod 72 to be forced up tube 70 by spring 73, thus releasing a catch 74 pivoted to the lower end of tube 70, which in turn allows cover 54 to pivot, and the segments 61 to drop. The upper and lower edges of the segments are formed to interengage with each other, (Fig. 2, not shown). Other embodiments (Figs. 3, 4, not shown) have different catch mechanisms. A rewind mechanism, involving a winch, is illustrated in Fig. 5 (not shown). A further embodiment, Figs. 6-8 (not shown), the rungs (123) extending alternately on opposite sides of cylindrical segments (122).
