Abstract: |
A fire fighting apparatus for confining a fire to an immediate area defined by a plurality of fire retardant curtains which are dropped from container cabinets upon actuation of a release mechanism which may be triggered manually or coincidentally with the actuation of a fire extinguishing device associated with the mechanism to be patented. In a preferred form, a plurality of fire retardant curtains are stored in a plurality of modular cabinets which are suspended from a ceiling covering the area to be protected. The release mechanism which allows the curtains to drop from one cabinet is connected to the release mechanism of adjacent cabinets for simultaneous operation of all associated cabinets. In use, operation of an automatically actuated fire extinguishing system, such as discharge of carbon dioxide to the area to be protected, causes a gas pressure drop serving to actuate the trigger mechanism which allows each door lock to move toward a released position to which it is normally biased. In the extended position, the curtains have their edges disposed adjacent one another so as not only to confine the extinguishing gas to a desired area but also to permit workers to escape through the curtains or fire fighting personnel to enter therethrough.

I claim:
1. A fire fighting apparatus comprising, in combination, a plurality of individual cabinets disposed adjacent one another so as to define at least partially the periphery of an area to which a fire may be confined, each of said cabinets comprising a pair of side walls and a bottom door extending between said side walls at the lower margins thereof, said door being adapted to move between an open and a closed position, a curtain disposed within each cabinet, each curtain having one end portion thereof fixed to a portion of its associated cabinet and the other end thereof free from said cabinet, said curtain being adapted to be folded into a relatively small volume so as to be able to be disposed within said cabinet and to be supported therein by said door when said door is in said closed position, a latching mechanism for holding said door in said closed position and for releasing said door to allow it to move to said open position thereof, said latching mechanism including a latch unit having a nose portion adapted to engage said door in one position of said latch unit and to be disengaged from said door in another position of said latch unit, spring means urging said latch unit under a predetermined force to said disengaged position, a link system having one portion thereof fixed in relation to said cabinet, another portion thereof adapted to engage a movable retainer assembly, and a still further portion attached to said latch unit, a movable retainer assembly including mounting links and a retainer bar, said retainer bar having end portions adapted for operative attachment to a corresponding bar on an adjacent cabinet, one of said bars being operable in response to a single triggering signal, whereby, said triggering signal will cause movement of said retainer bars, movement of said link system, and permit latch movement to cause said doors of said cabinets to be opened simultaneously.
