with an internal chamber (4) for housing a charge (5) of a
solid substance which can be transformed, at a predetermined
temperature, into an aerosol with flame-extinguishing
properties. A delivery opening (7) puts the chamber (4)
into communication with the exterior. An explosive starting
capsule (10), associated with a striker mechanism (13), is
provided for triggering the reaction of the extinguishing
charge (5).
Description
- The present invention relates to a portable aerosol fire-extinguisher of the type comprising a hollow casing defining in its interior a chamber for housing a solid substance which can be transformed, at a predetermined temperature, into an aerosol with flame-extinguishing properties, and which can be discharged in aerosol form through an opening which puts the chamber housing the extinguishing charge into communication with the exterior. A portable fire-extinguisher of the above-mentioned type is known, for example, from patent publication WO-00/37142.
- In devices of this type, an electrical resistor, supplied by batteries, via a switch, is provided for triggering the transformation of the extinguishing charge from solid to aerosol. Fire-extinguishers of the above-mentioned type have a disadvantage which is connected with the limited endurance of the batteries over time. As is known, batteries in fact become discharged after a number of months and, unless the user remembers to replace them periodically, there is a risk that the fire-extinguisher will not operate when required because the batteries are discharged.
- The object of the present invention is therefore to provide a portable aerosol fire-extinguisher of the type specified at the beginning, addressing principally the problem of ensuring reliability of operation over time and the capacity to be activated very quickly when required.
- These and other objects and advantages which will be understood better from the following description are achieved, according to the invention, by a portable aerosol fire-extinguisher having the characteristics defined in the appended claims.
- The structural and functional characteristics of a preferred but non-limiting embodiment of a portable fire-extinguisher according to the invention will now be described; reference is made to the appended drawing which is a schematic view showing a portable fire-extinguisher according to the invention in axial, longitudinal section.
- With reference to the drawing, a portable fire-extinguisher comprises a supporting
body 1 which is made of plastics material and is shaped so as to form ahollow handle portion 2, and an elongatetubular casing 3 with adistal end 3a and aproximal end 3b which is fixed to theplastics body 1. Achamber 4 is defined inside thehollow casing 3 for acharge 5 of a solid substance which can be transformed, at a predetermined temperature, into an aerosol with flame-extinguishing properties. - The chemical and physical characteristics of the
extinguishing charge 5 are not relevant per se for the purposes of an understanding of the invention and will not therefore be described in detail herein. By way of indication, the extinguishing charge is a compacted mixture comprising potassium nitrate, a binding resin, and an organic oxidizing agent. - A
metal plug 6 is fixed at thedistal end 3a of thetubular metal casing 3 and forms a delivery opening or nozzle 7 which puts theinternal chamber 4 into communication with the exterior. Preferably, both thecasing 3 and theplug 6 are made of metal, for example, aluminium. Directly on the inner side theplug 6, there is aperforated metal diaphragm 8 with a solidcentral portion 8a and one or morelateral holes 8b the purpose of which will be explained below. - The
extinguishing charge 5 is shaped so as to form a longitudinal duct orpassage 9. Terms indicating directions and orientations such as "longitudinal" and "transverse" or "radial" are intended to be understood herein with reference to the longitudinal central axis X of the fire-extinguisher, unless indicated otherwise. Similarly, terms such as "front" and "rear" refer to the distal portion and to the proximal portion of the fire-extinguisher, respectively, with reference to the normal condition of use in a user's hands. - The
longitudinal passage 9 puts thedistal end 5a of the aerosol-formingcharge 5 into communication with the central portion of the fire-extinguisher where, according to the invention, an explosive-capsule starting device is provided. Anexplosive capsule 10 is held in afront compartment 11 formed by atubular insert 12 mounted centrally inside the supportingbody 1. A firing mechanism, generally indicated 13, comprises astriker element 14 with an enlargedhead 14a housed coaxially inside theinsert 12 and a striker-operating spring 15, interposed between thehead 14a and a reaction surface 16 which is oriented transversely relative to the principal longitudinal axis of the fire-extinguisher. The reaction surface 16 is formed by a cup-shaped body 17 which is housed in the supportingbody 1, to the rear of and adjacent theinsert 12. The cup-shaped body 17 forms acavity 18 which is open at the rear. - A resilient, fork-
shaped retaining element 21 at least partially housed in therear cavity 18 of the cup-shaped body 17 has twoarms free ends portion 14b formed at the proximal or rear end of thestriker 14. Thearms rear cavity 18. - The operating principle of the fire-extinguisher is based on the chemical reaction which, when triggered by the starting device constituted by the
explosive capsule 10 and by thestriker mechanism 13, brings the mixture of potassium salts to a temperature of about 300°C, giving rise to an exothermic reaction which produces an aerosol suspension of particles of extremely small particle size; these particles, which are discharged from thechamber 4 through the nozzle 7 owing to the pressure which accompanies the reaction, are spread over the source of a fire, inhibiting the combustion-supporting' effect of oxygen and suffocating the propagation of the fire. - The fire-extinguisher according to the invention operates as follows. When the user sees the need, he grips a
gripping ring 22 and pulls the fork-shaped element 9, by means of acord 23, in the direction indicated by the arrow A in the drawing. Theelement 9 moves backwards, sliding along thecavity 18, withdrawing thestriker element 14 by means of the hookedends rear cavity 18, thearms rear end 14b of the striker which is acted on by the spring and returns sharply to the initial position shown in the drawing, striking thestarting capsule 10, which explodes. The small flare resulting from the explosion of thecapsule 10 is propagated through theduct 9 in the extinguishing charge, reaches the flame-diffuser diaphragm 8 and is reflected thereby, so as to be radiated against thedistal end portion 5a of theextinguishing charge 5, triggering its chemical reaction. The aerosol fluid produced by the combustion of the extinguishing charge is discharged energetically from the hole 7a in the delivery plug and can be directed towards the fire. - As will be appreciated, the effectiveness of the fire-extinguisher according to the invention can be guaranteed for much longer periods of time than in conventional fire-extinguishers of the type discussed in the introductory portion of the present description and the fire-extinguisher does not require any maintenance or periodic checks.
- It is intended that the details of construction of the fire-extinguisher may be varied widely with respect to those described and illustrated. For example, the selection to form the passage duct in the central portion of the extinguishing charge constitutes a preferred selection but is certainly not essential for the purposes of the implementation of the invention. In particular, the
passage 9 could alternatively be arranged in a lateral position rather than a central position, at the interface between the explosive charge and themetal casing 3, for example, by the formation of a longitudinal groove along one side of theextinguishing charge 5 and/or by suitable shaping of thecasing 3. Moreover, the selection to form the fire-extinguisher in a manner such that the reaction which produces the aerosol starts in the distal portion of the extinguishing charge also constitutes a preferred selection since it enables the temperatures to be lower in the region closer to the handle, in comparison with an alternative configuration in accordance with which the triggering reaction would start in the immediate vicinity of theexplosive capsule 10 and the aerosol would reach the nozzle 7 by being propagated through thepassage 9. Finally, in an alternative embodiment (not shown), thediffuser diaphragm 8 may be eliminated and its functions may be performed by the internal surface of thedelivery plug 6.
