And via the driven gear 212, the drum 207 is also braked, preventing the drum 207 from rotating beyond a predetermined rotational speed.

The movable evacuation platform 21 under such braking operation is smoothly rotated from the hanging position to the horizontal collapsed position without exceeding a predetermined rotational speed.

Further, when returning from a horizontal fallen position to a vertical position, first, the evacuation equipment 28 is stored, then the nozzle 213 is attached to the drive shaft 208, and the drive shaft 208 is rotated by the handle 213.

When the drive shaft 208 is rotated, the drum 207 is rotated via the drive gear 211 and the driven gear 212, and the wire
Rope 214 is wrapped around drum 207.

Therefore, the movable evacuation platform 21 is rotated from a horizontal, fallen position to a vertical position.

According to the above invention, the movable evacuation platform is equipped with a handrail,
In addition, the base part is rotatably connected to the tip of the outdoor floor on the upper floor that protrudes from the outer wall of the building, and the base can be placed in an upright position with respect to the outdoor floor or in a collapsed position outside of the handrail. When the rotating and extendable evacuation equipment is extended from the evacuation opening of the movable evacuation platform, the lower end extends near the handrail placed on the outdoor floor of the floor directly below it, so the outdoor floor of the floor immediately below it is extended. By using the handrail installed on the floor, it is possible to evacuate to the outdoor floor on the floor directly below, and as a result, the length of the evacuation equipment when extended is shortened and lightened. As a result, the lateral deflection of the extended end of the extended evacuation device is reduced, making evacuation easy, reliable, and safe, and in addition, without forming an opening in the outer wall of the building. It is easy to install in existing and newly constructed buildings, reduces production and installation costs, and allows the creation of an evacuation route that connects the outdoor floor on the upper floor with the outdoor floor on the floor immediately below.
The setting operation is easy and quick, and a large number of evacuees can be evacuated in a short time.In addition, the top cover is rotatably connected to the tip of the movable evacuation platform, and the movable evacuation platform Since it can be rotated between a standing position on the top surface and a position where the top opening of the evacuation passage is closed, the top cover prevents evacuees from falling and also alleviates their fear during evacuation. This makes evacuation easier, safer, more reliable, and faster, and the lid eliminates the need for a fence to prevent falls, which reduces the number of parts and makes it easier to manufacture. Costs are reduced.
