To explain the case of using the evacuation device 1L12 of No. 01 to evacuate from the third floor 201 to the ground level in the event of a fire, the resident first moves the manual lever 158 to the evacuation platform locking device 31.
By operating a lever, the drive shaft 108 is rotated, and the latch 1 is attached to the drive shaft 108 through the drive mechanism 102.
Pull out the latch receiver from the mouth and lock the evacuation platform locking device 31.
, and then move the movable evacuation platform 16 forward, that is,
Push outward to rotate the movable evacuation platform 16 around the support shaft 53.

In this way, when the movable evacuation platform 16 starts rotating around the support shaft 53, the column side link 60 of the support device 17 moves to the pin 6.
2, and the movable evacuation side link 6
1 also begins to rotate around the pin 63, so the drive arm of the vertical interlocking mechanism 33 rotates upward around the pin 62.

As the drive arm rotates upward, the connecting rod is pulled upward, and as the connecting rod is pulled upward, the long bar ← section is pulled upward, and the release lever rotates around the support shaft. Start rotating.

When the movable evacuation platform 16 is further rotated so as to approach the horizontal position, the release lever is further rotated around the support shaft, and a portion of the similar lever pushes the interlocking lever 157, causing the drive shaft 10
8 to release the evacuation platform locking device 31 of the movable evacuation platform 15 on the second floor 200.

That is, the latch 100 is pulled out from the latch receiver via the drive mechanism 102.

Therefore, the movable evacuation platform 15 on the second floor 200 begins to rotate from the vertical upright position to the horizontal fallen position.
