Abstract

PURPOSE: To prevent the inflow of smoke to a cage when there happens a fire, by mounting a compressed air bomb to the cage, and by interlocking the bomb with a fire detector.
CONSTITUTION: A bomb 6, in which compressed air is filled, is installed to an upper portion of a carge 4, and the bomb is communicated with the inside of the cage 4 by a piping with a valve 7 while the valve 7 is driving connected to a fire detector 5 mounted to a bottom of the cage 4. Thus, when there happens a fire in buildings and the fire detector 5 detects smoke, poisonous gases, etc. flowing into a rise-and-fall course 1 from the clearances of doors at platforms, the valve 7 is opened, compressed air in the bomb 6 is discharged into the cage 4 and smoke, poisonous gases, etc. in the rise-and-fall course 1 cannot enter the inside of the cage 4. And the opening of the valve 7 may manually be operated by passagers.
