建物の階床で火災が発生すると、エレベータの昇降路は
煙突状態となり、火災が昇降路を通じて他階に広がつた
り、延焼したりする虞れがある。When a fire breaks out on a floor of a building, the elevator shaft becomes like a chimney, and there is a risk that the fire may spread to other floors through the shaft.
そこで、昇降路を火災時に煙突状態にしないような工夫
が必要である。それには昇降路内に送風機によつて風を
送り、昇降路内の空気圧力を高めることが考えられる。
しかし、そのための装置は大形のものとなつて高価てあ
ると共に、空気漏れ等の影響を考慮すると、昇降路全体
を火災時の煙玉に打ち勝つまて加圧することは技術的に
もかなり困難である。Therefore, it is necessary to devise ways to prevent the hoistway from becoming a chimney in the event of a fire. One possible way to do this is to use a blower to blow air into the hoistway to increase the air pressure inside the hoistway.
However, the equipment for this purpose is large and expensive, and considering the effects of air leakage, it is technically quite difficult to pressurize the entire hoistway to overcome the smoke bomb in the event of a fire. It is.

The fire floor arrival relay 24 is self-maintained by the circuit 24-(-). When car 9 stops, travel relay contact 2
1c is open, and at this time, the car position contact 4D is open, so the 4th floor car call relay 4C is deenergized, and the contact 4
Ca~4CC is open. On the other hand, traveling relay contact 21e
is also closed, so (+)-24b-21e-22b-2
The fire control relay 25 is activated by the circuit 3b-25-(-).
is energized, and contacts 25a and 25b are closed. Contact 25
By closing a, the drive device 26 operates to rotate the disk 14 in the direction of arrow A. Now, the shield plates 16 around the four circumferences of the car 9 rotate via the links 15, and when their front edges come into contact with the walls of the hoistway 7, the drive device 26 operates to rotate the discs 14. Stop. Further, by closing the contact 25b, the electric motor 27 is driven and the blower 11 is rotated. During this time, the door opening relay 28 is not energized due to the opening of the contact 20c, so the car door 10 and the landing door 8 are not energized.
remains closed. In this way, when the car 9 arrives at the fire floor, the shielding plate 16 moves forward to close the gap between the landing and the hoistway 7, and the blower 16 closes the car door 10.
1 to start blowing air. As a result, the pressure inside the car 9 is increased, and the fire and smoke that enters the car 9 from the landing are pushed back. Therefore, fire and smoke are prevented from entering the hoistway 7 and the car 9 from the landing. When the fire is extinguished and there is no danger, and the changeover switch 6 is opened, the operation control relay 20 is deenergized, the contacts 20a and 20b are opened, and the contact 20c is closed.

ンを用いるようにしてもよい。By opening contact 20b, fire floor arrival relay 24 is deenergized and contacts 24a and 24b are opened. By opening the contact 24b, the fire control relay 25 is deenergized and the contacts 25a,
25b is open. The opening of the contact point 25a causes the drive device 26 to operate and rotate the disk 14 in the opposite direction of arrow A. With this, the shield plate 16 rotates and returns to the old position, and then the disc 14 is stopped by the operation of the drive device 26. Moreover, the electric motor 27 is stopped by opening the contact point 25b, and the air blowing by the blower 11 is also stopped. This returns the car 9 to its normal state. In the embodiment, the shielding plate 16 that moves forward and backward is described as the shielding device 12, but the present invention is not limited to this, and an air curtain installed in the same position may be used.

It is possible. As explained above, in this invention, in the event of a fire, the elevator car is run and stopped at the fire floor, and then the door is kept closed, and the shielding device installed on the car is used to provide a shield between the landing and the hoistway. At the same time, a blower installed inside the car blows air into the car, which prevents fire and smoke from entering the hoistway and inside the car from the elevator and prevents the spread of fire to other floors. can.
