Further, the support frame 8 is provided with a starting device (not shown) made of a spring or the like to facilitate the start of sliding of the movable landing 5. The movable landing 5 is further provided with a closing plate 12 at its front end to close the opening 3 so as to substantially coincide with the outer wall 2 when it is pulled into the storage section 4. The gap between the inner circumferential edge of the opening 3 and the outer circumferential edge of the closing plate 12 is provided with a gasket so as not to obstruct the sliding movement of the emergency movable landing 5 and to prevent rainwater from normally infiltrating into the inside of the building. It is filled with sealant, etc. The staircase part 6 which is attached substantially horizontally to the movable landing 5 and rotates downward when in use has an entrance/exit 13 formed in the movable landing 5 with its root side as a pivot.
The movable landing 5 slides and is pulled out toward the outer wall 2 by being pivotally mounted nearby and connected to a wire rope 14 wound around a winding device 21 formed on the movable landing 5 at its tip end. In this state, the winding device 21 is unlocked, and by its braking action, when the staircase portion 6 rotates in the direction of the arrow shown in FIG. is controlled so that its leading end side lands softly on the movable landing 5 provided on the lower floor, thereby forming a stair passage having a constant inclination angle between the movable landings 5 on the upper and lower floors. Further, on the upper surface of the movable landing 5, a foldable fence 15 is formed to stand around the movable landing. This foldable fence 15 is connected at its base via a locking tool 16, and when stored, the foldable fence 15 is folded down onto the upper surface of the movable landing 5, and the movable landing When it protrudes, the locking tool 16 is automatically unlocked and is erected upward to surround the surrounding area.
