A portable aerosol fire-extinguisher has an elongate metal casing (3) with a handle (2) and 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, and which is delivered through an opening ( 7). An inflammable charge (13) which can be ignited by means of an activation element (14, 16) is provided for triggering the reaction of the extinguishing charge (5). The activation element can be operated manually in order to produce friction between the inflammable charge (13) and the activation element (14, 16), such as to bring about ignition of the inflammable charge (13).

What is claimed is: 1. A portable aerosol fire-extinguisher, comprising: an elongate metal casing with a distal end, a proximal end fixed to a handle, and an internal chamber for housing a charge of a solid substance which can be transformed, at a predetermined temperature, into an aerosol with flame-extinguishing properties, a delivery opening in the region of the distal end for putting the chamber into communication with the exterior, and starting means disposed in the vicinity of the extinguishing charge for triggering the reaction thereof, wherein the starting means comprise an inflammable charge which is ignited by means of an activation element which is enclosed in an inactive condition and is moved manually in order to produce friction between the inflammable charge and the activation element to ignite the inflammable charge, wherein the delivery opening is formed in a transverse baffle in the distal end region of the casing, and wherein said inflammable charge is held in the delivery opening in the transverse baffle. 2. The fire-extinguisher of claim 1, wherein the activation element is provided with a surface which is rough or suitably prepared with a mixture and is configured to rub against a surface of the inflammable charge and ignite the inflammable charge. 3. The fire-extinguisher of claim 2, wherein the activation element is associated with the fire-extinguisher in a manner such that, in an inactive condition, the activation element is held remote from the inflammable charge and, in an active condition, can be brought into contact with a surface of the inflammable charge in order to ignite it by friction. 4. The fire-extinguisher of claim 1, wherein the inflammable charge includes at least one substance or a mixture of substances selected from the group consisting of: phosphoric mixtures, phosphorus sesquisulphide, oxidizing substances such as potassium chlorate, potassium chromate and dichromate, manganese oxide, inert substances suitable for promoting friction during rubbing, such as glass dust, fossil flour, adhesives such as glues, combustible substances such as sulphur, resins. 5. The fire-extinguisher of claim 1, wherein the extinguishing charge is a compacted mixture comprising potassium nitrate, a binding resin, and an organic oxidizing agent. 6. The fire-extinguisher of claim 1, wherein the outer surface of the inflammable charge projects or is arranged level with an outer surface of the transverse baffle. 7. The fire-extinguisher of claim 1, further comprising a protective cover mounted removably on the distal end of the casing to protect the inflammable charge in an inactive condition. 8. The fire-extinguisher of claim 3, wherein the activation element is fixed to a manual gripping means mounted removably on the fire-extinguisher. 9. The fire-extinguisher of claim 8, wherein the activation element is formed as a plug which can be inserted in a cavity of the handle in order to hold the surface in a position in which it is protected from the exterior in the inactive condition. 10. The fire-extinguisher of claim 1, further comprising a delay fuse interposed between the inflammable charge and the extinguishing charge. 11. The fire-extinguisher of claim 1, wherein the inflammable charge is held on the transverse baffle.
