Abstract

A fire extinguishing apparatus comprising of a metal dome, a deformable cylindrical section that can store a volume of gas, and a plurality of hanging canvases, around its perimeter as well as internally. Said volume of gas is the by-product of combustion, which is captured once the apparatus is place over and encapsulates the fire. As the apparatus is lowered onto the fire, the perimeter canvases form a seal, limiting the amount of oxygen inside the volume. As the fire consumes this limited amount of oxygen, the toxic gases produced are stored in its chamber, the apparatus continues being lowered onto the fire were the compression canvases compact the fire flames, extinguishing them. Furthermore, as the device continues to be lowered even further, the deformable cylindrical section begins to displace its stored volume of gases on to the encapsulated fire, displacing any remaining oxygen and stopping the combustion process.

Claims3

Dependent claims

A fire extinguishing apparatus, having a top rigid metallic dome member that defines an upper metallic circular frame, wherein a flexible chamber composed of a first set of exterior flexible canvases are suspended from said upper metallic circular frame, and contains a set of metallic bars across the interior of said upper circular frame, which form an internal configuration;

wherein a set of internal compression canvases are suspended from said set of metallic bars, which attack the fire through encapsulation and compression and thereby reduce the amount of air that surrounds the flames and stops the combustion process efficiently;
wherein said set of internal compression canvases compress and deform without obstructing each other and thus efficiently suppresses the flames;
wherein said flexible chamber has attached on a lower end a lower metallic circular frame, wherein a second set of exterior flexible canvases are suspended from the lower metallic circular frame, which extend the original area covered by the apparatus and thus increase the apparatus'attack capacity;
wherein said set of internal compression canvases and said second set of exterior flexible canvases have a length that when the apparatus is not collapsed, both sets of canvases touch the ground;
and wherein both sets of flexible canvases are compacted when the apparatus is collapsed and recover their initial form after the apparatus is taken to a non-collapsed position.
