Next, the second floor 200 and the third floor 2 configured as described above are
If a fire breaks out using the evacuation devices 11 and 12 of 01,
To explain the case of evacuation from floor 201 to the ground level,
The resident first moves the manual lever 158 to the evacuation platform locking device 3.
1, the drive shaft 108 is rotated by lever operation, the launch 100 is pulled out from the latch opening 101 via the drive mechanism 102, the evacuation platform locking device 31 is released, and then the movable evacuation platform locking device 31 is released. Push the platform 16 forward, that is, outward, and move the movable evacuation platform 1 around the support shaft 53.
Rotate 6.

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 154 of the vertical interlocking mechanism 33 rotates upward around the pin 62.

As the drive arm 154 rotates upward, the connecting rod 1
56 is pulled upward, and as the connecting rod 156 is pulled upward, the long lever portion 161 is pulled upward, and the release lever 155 begins to rotate around the support shaft 160.

When the movable evacuation platform 16 is further rotated so as to approach the horizontal position, the release lever 155 is further rotated around the support shaft 160, and the short lever portion 162 is rotated further toward the interlocking lever 157.

Since the drum is rotated as the wire rope 170 is let out, the rotation of the drum is controlled by the driven gear 19.
1. Transmitted to the brake shaft via the drive gear.

When the brake shaft is rotated in this manner, the fly weights are opened on both sides of the brake shaft, depending on the rotational speed of the brake shaft.

In response to such opening movement of the fly weights, the movable brake lining plate is pressed against the stationary brake lining plate by the cam surface against the return spring.

Therefore, the friction plate is sandwiched between the movable and stationary brake lining plates, and the brake shaft is braked.

When the brake shaft is braked, the drum is also braked via the drive gear and driven gear 191, and the drum is prevented from rotating beyond a predetermined rotational speed.

Movable evacuation platform 15.16 under such braking action
is smoothly rotated from a vertical position to a horizontal tilted position without exceeding a predetermined rotational speed.

On the other hand, the evacuation device 11 on the second floor 200, in the same way as the evacuation device 12 on the third floor 201, artificially drives the hoist 97 and pulls up the evacuation device 27 that has been lowered and extended via the wire rope. , is locked by a ratchet mechanism, and the evacuation device 27 is further rotated around the support shaft 96 and housed in the evacuation opening 18 in a horizontal position as shown in FIG.

In addition, in the same manner as the evacuation device 12 on the third floor 201, the movable pin is artificially moved upward along the elongated hole, the movable pin is removed from the pawl, and the drive mechanism of the lid locking device is returned to its original state by the return spring. Return the upper and lower lids 24 and 25 to the
Close.

At this time, by manual operation, the bar holder engages the rotary opening with the opening, and the upper and lower lids 24 and 25 are locked in the evacuation openings 18 and 19.

As such, the evacuation equipment 11 on the second floor 200 and third floor 201
, 12 are locked to the evacuation openings 18, 19, the movable evacuation platforms 15, 16 are artificially erected in the vertical position in order from the second floor side to the third floor side.

First, on the movable evacuation platform 15 on the second floor 200, a bundle is attached to the brake shaft of the gradual hoisting device 34 and rotated.

In that way, when the brake shaft is rotated artificially through the bundle, the drum of the hoist will rotate between the driving gear and the driven gear 1.
91 and the wire rope 170 is wound around the drum.

Therefore, the movable evacuation platform 15 is rotated around the support shaft 53 and erected to a vertical position.

Therefore, the movable evacuation platform 15 is locked by the evacuation platform locking device 31.
Lock it to the evacuation platform holder 29°30.

That is, by operating a manual lever, the drive shaft 108 is rotated, the latch 100 is inserted into the latch receiver opening 101, and the movable evacuation platform 15 is locked to the evacuation platform receivers 29 and 30.

Next, the movable evacuation platform 16 on the third floor 201 is erected to a vertical position and locked to the evacuation platform holders 29 and 30 by the same operation as the movable evacuation platform 15 on the second floor 200.

When the movable evacuation platform 16 on the third floor 201 is raised to the vertical position, the upper and lower floor interlocking mechanism 33 returns to its original state, and the evacuation platform 16 on the second floor 201
And the lid locking device 3 of the evacuation device 11゜12 on the third floor 201
2 also returns to its original state.

In this way, the evacuation devices 11 and 12 on the second floor 200 and the third floor 201 are returned to their original state and prepared for the next fire.

According to the present invention having the above structure, the movable evacuation mold evacuation on the upper and lower floors is achieved by interlocking the interlocking arm of the evacuation platform locking device on the upper floor and the interlocking arm of the evacuation platform locking device on the floor immediately below. Since the devices are interlocked, if the interlocking arm of the evacuation table locking device on the upper floor is operated incorrectly, the movable evacuation mold evacuation device on the floor directly below will be prevented from operating, and the evacuation device can be made into a unit and manufactured in a factory. At the same time, an interlocking mechanism for upper and lower floors for a movable evacuation mold type evacuation device is obtained, which greatly facilitates installation in buildings, whether new or existing.
