Fire and disaster evacuation apparatus

A fire and disaster evacuation apparatus installed in a high-rise building, the apparatus comprising:

• a stationary frame installed at a door frame edge of a building outer wall instead of a gallery window, wherein the stationary frame comprises a rectangular frame, an auxiliary rectangular frame formed at a center of an entire inner surface of the rectangular frame to protrude along edges of the rectangular frame, and a flange formed by being bent outwardly from an edge of each surface located on an interior side of the rectangular frame;
• a front plate having a size corresponding to the rectangular frame of the stationary frame and having a plurality of reinforcement frames in an entire inner surface, wherein the plurality of reinforcement frames comprises vertical reinforcement frames and horizontal reinforcement frames, and wherein a pivotable ladder is provided in the front plate;
• a side plate comprising a first foldable plate and a second foldable plate, which are fixedly fastened to vertical frames on both sides of the auxiliary rectangular frame of the stationary frame and the front plate with a plurality of first connection hinges;
• a bottom plate fixedly fastened to a lower horizontal frame of the auxiliary rectangular frame with a plurality of second connection hinges, wherein an auxiliary ladder is provided in the bottom plate;
• a locking device comprising a hooking part and a latch part, wherein the hooking part is installed at a position corresponding to the vertical frames on the both sides of the auxiliary rectangular frame of the stationary frame and the front plate and is fixedly fastened at a position that does not overlap a position at which the side plate is fastened;
• and
• a lever part comprising two lever members coupled to the locking device and a lever handle connecting the two lever members,
• wherein a width of the fire and disaster evacuation apparatus in a folded state is less than a thickness of an outer wall of the building, so that the apparatus is located inside a wall body without protruding outside the wall body, wherein an inversed L-shaped lever fixedly is fixedly installed at an inner surface of the vertical frame on one side of the auxiliary rectangular frame of the fixing frame to be movable upward and downward,
• wherein a ¬-shaped lever is fixedly installed at a lower rear surface of a vertical frame on one side of the auxiliary rectangular frame of the stationary frame to be movable upward and downward
• wherein one of the two lever members of the lever part is hung on the inversed L-shaped lever,
• wherein a connection wire connects the ¬-shaped lever of a current floor and the inversed L-shaped lever of a lower floor, and
• wherein when the ¬-shaped lever of the current floor is moved upward, the inversed L-shaped lever of the lower floor is moved upward by the connection wire and the lever part is then pulled upward by the inversed L-shaped lever to release the locking device, thereby opening and driving a fire and disaster evacuation apparatus of the lower floor.
