Since the evacuation device of the present invention is configured with an extensible evacuation device that is stored in the evacuation entrance, firstly, large-scale installation work can be omitted, and installation on the supporting wall is extremely easy. Moreover, a plurality of evacuation devices are vertically arranged at intervals, and the evacuation equipment in the upper and lower evacuation devices are alternately lowered from above to below within the range of the outdoor floor, and the evacuation devices are sequentially lowered. As a result, the installation space becomes extremely narrow, making it possible to form an evacuation route that connects sequentially from the top to the bottom, and allowing the upper and lower evacuation devices to be put into use without being interlocked with each other. The evacuation equipment can be set easily, the evacuation equipment can be set easily, and the evacuation equipment can be set easily, and the evacuation equipment can be set quickly and reliably.
Even though the evacuation equipment is in a lowered and extended state and its lower end is free, it is made into a rigid body and suspended from the outdoor floor. stability is maintained, the sense of fear during evacuation is alleviated, it is possible to evacuate safely and with peace of mind, and a large number of people can evacuate in a short period of time. It is extremely easy to attach supporting walls, i.e. to the exterior walls of buildings or to the side walls of large mechanical equipment. It can also be applied to mammoth fire boats, submarine oil drilling equipment, etc. Especially when evacuation equipment is installed in a multi-story building, an opening must be made in the outer wall of each floor. However, with a fence as a protective measure, the fence makes the opening feel like a window and does not spoil the appearance of the building, thus greatly increasing its applicability to buildings, and When installed in a multi-story building, when in use, not only can evacuation routes be constructed that connect each floor to each other, but also multiple adjacent floors can be connected to each other between all floors of the building. Connecting evacuation routes can now be constructed, and upper and lower floors can be connected without the need for interlocking means.Furthermore, it has become possible to unitize and reduce the number of units, improving productivity in factories, and improving structure. It is easy to use, unitization reduces manufacturing costs, and facilitates transportation.Moreover, installation is simple and the installation period is shortened.

However, from the specific examples of the present invention described above with reference to the drawings, various modifications and changes will be easily made by those who have ordinary knowledge in the technical field to which this invention pertains. Furthermore, the configuration of this invention can be easily replaced by an embodiment essentially the same as this invention, which satisfies essentially the same tasks as that invention and achieves the same effects as this invention. Let's do it.
