Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher for a passenger conveyor such as an escalator and an automatic line.

[0002]

2. Description of the Related Art Conventionally, this type of apparatus is disclosed in
As described in JP-143263A, a plurality of steps are connected endlessly and circulate while traveling between two entrances and exits, and skirt guards provided adjacent to both sides of the row of steps, In a fire extinguisher of a passenger conveyor provided with an oil pan that is disposed below the step train and receives oil, dust, sand, and the like descending from above, the fire extinguishing device is located above the oil pan and at a side position of the step sequence. There is known a fire extinguisher for a passenger conveyor, in which a fire extinguisher enclosed in a container which partially or entirely melts at a relatively low temperature is arranged.

[0003]

In the above-mentioned conventional apparatus, the fire extinguishing agent is arranged above the oil pan, but the space above the oil pan is a narrow space, and the fire extinguishing agent is installed unless the steps are removed. I can't.

[0004] It is an object of the present invention to provide a fire extinguisher for a passenger conveyor which can be easily installed without removing a step.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a step which is connected endlessly and circulates while traveling between two entrances, and a skirt guard provided adjacent to both sides of the step row. A machine room formed below the entrance,
In a fire extinguisher of a passenger conveyor provided with an oil pan which is arranged below the step train and receives oil, dust, sand and the like descending from above, a lower part of a cover plate closing an opening of the machine room, Alternatively, this is achieved by providing a structure in which a fire extinguisher composed of a container in which the whole melts at a relatively low temperature and a fire extinguisher enclosed in the container is attached.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIG.

In FIG. 1, reference numeral 1 denotes a step which is connected endlessly and circulates while traveling between two entrances, 2 denotes a skirt guard provided adjacent to both sides of the step 1 and 3
Is a machine room formed below the entrance and exit, 4 is an oil pan that is arranged below the step 1, and receives oil, dust, sand, etc., descending from above, 5 is a cover plate that closes the opening of the machine room 3 , 6 are a container 6A in which a part or the whole dissolves at a relatively low temperature, and a fire extinguisher enclosed as a fire extinguisher, and 7 is a holder for mounting the fire extinguisher 6. The fire extinguisher 6 is attached to the lower surfaces of the plurality of cover plates 5 via holding members 7.

Next, the operation of this embodiment will be described.

The gap between the step 1 and the skirt guard 2 or the gap between the steps 1 is transported to the vicinity of the entrance by the step 1, and the tobacco and other equipment installed in the machine room 3 are heated by the tobacco and other equipment installed in the machine room 3. When a fire is ignited from the vicinity, the fire extinguisher 6
Since it is attached to the upper part of the machine room 3 by the holder 7, even if a fire occurs near the machine room 3, the heat causes the container of the fire extinguisher 6 directly above to melt and break, and the fire extinguisher inside is scattered. It falls near the ignition point and is extinguished early in the fire.

According to the present embodiment, since the fire extinguisher 6 is attached to the lower surface of the cover plate 5, the fire extinguisher 6 can be easily installed without removing the steps 1.

[0011]

As described above, according to the present invention, the fire extinguisher is mounted on the lower surface of the cover plate that closes the opening of the machine room, so that the fire extinguisher can be easily installed without removing the steps.
