Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an evacuation device installed on an upper outdoor floor protruding from the outer wall of a building, such as a balcony, a verandah, an outdoor hallway, etc.

Traditionally, evacuation devices installed in buildings, especially mid-to-high-rise buildings, are mainly escape chute bags, rope ladders, slow descent ropes, etc., and these evacuation devices are usually stored in storage boxes on the indoor side near windows and entrances. It is stored and installed.

When in use, the escape chute bag, rope ladder, etc. are first taken out of the storage box and dropped through a window or doorway, and the lower end is fixed in a predetermined position by an evacuation guide waiting on the ground or by a third party to ensure safety. After checking, evacuees will evacuate to the ground.

Therefore, such evacuation equipment requires a relatively long time to prepare for use, and it is difficult to quickly evacuate a large number of evacuees at the same time. There is a limit to the height of the building, and it cannot be installed on high floors for safety reasons.

In addition, conventionally, there are evacuation stairs that are equipped with fixed ladders, ramps, etc. on the exterior walls of buildings, but these have the potential to be used for trespassing such as theft, so the entrance doors are locked from the inside. Also, by placing things on the indoor side of the door,
In the event of a fire, the door may not open quickly, resulting in many casualties.

This type of evacuation staircase is a relatively reliable means of evacuation equipment at present, except for the artificial and incomplete management described above.

However, on the other hand, because such evacuation stairs are always installed protruding from the outer wall of the building, the size and location of such evacuation stairs are more important than the safety of the people living in the building. Furthermore, evacuation stairs in mid-to-high-rise buildings have become large-scale, detracting from the beauty of the building.

Furthermore, an evacuation device has been proposed that is normally formed as a part of the outer wall of a building and is housed in an opening in the outer wall, and when a fire occurs, the evacuation device is rotated to form a veeranda and serve as an evacuation site. However, there are many unresolved technologies regarding evacuation operations, operating functions, and durability against natural conditions, and when installing it in an existing building, an opening must be formed in the exterior wall. For this reason, it has not yet been commercialized.

The purpose of this invention is to enable unitization, factory production, extremely easy construction in new and existing buildings, and in addition, to connect the upper floor and the floor immediately below to form an evacuation route. At the same time, it is easy to operate, operates safely and reliably, quickly, and can evacuate a large number of evacuees in a short period of time.It is stable even in gusts of wind, making it possible to evacuate with peace of mind. It consists in providing evacuation equipment for buildings.
