Definitions

  • the invention relates to a fire extinguisher comprising a container intended to contain an extinguishing product, liquid or pulverulent, and a stopper fixing to screw on this receptacle, for closing it, this stopper comprising a lockable operating member, provided for actuating a means for opening an inert gas cartridge under pressure, removably attached to said screw cap, to be in the container and cause the extinguishant to exit the extinguisher, when said inert gas passes from the cartridge into the container.
  • a known fire extinguisher of this type is described in the certificate of addition FR-A-2 502 963, which comprises a handle which, after having been unlocked as is generally the case with fire extinguishers, requires, after that one transported the device, holding it by its handle, near the fire, an actuation operation of the same handle, to produce the working condition of the fire extinguisher, by puncturing a seal to put the container under pressure.
  • the present invention makes it possible to eliminate this maneuver from the handle which, under real fire conditions, can cause a loss of precious time, or even forget this maneuver and the uselessness of the extinguisher.
  • the solution consists in using the self-weight of the apparatus to produce, by an automatic displacement of the handle, the setting in working condition, of the simple fact of seizing and transporting by hand the extinguisher held by its handle.
  • the fire extinguisher according to the invention is in accordance with the claim.
  • Figure 1 is a section along 1-1 of Figure 3, showing the bodies in the rest position, the fire extinguisher then being ready for use.
  • Figure 2 is a view similar to Figure 1, but showing the organs in the position they occupy when the handle, which was in the inactive position in Figure 1, has passed into the working position.
  • Figure 3 is a plan view corresponding to Figure 1, the container body being omitted.
  • Figure 4 is a detail view in section along 4-4 of Figure 1.
  • Figure 5 is a sectional view on a larger scale, according to 5-5 of Figure 3.
  • the fire extinguisher shown comprises a container 1 intended to contain a non-illustrated extinguishing product, liquid or powdery, and a plug formed by a body 2 and a screw ring 3 which is fixed to a thread 4 of the container 1 to seal the container 1 by means of an O-ring 5, interposed between the container 1 and the body 2 of the plug.
  • a handle 6 which, when the container 1 is arranged vertically as shown in the drawing is approximately horizontal, is mounted to rotate around a pivot 7 passing through two arms 8, belonging to the body 2.
  • a safety pin 9 provided with a ring 10 passes through the part of the handle 6 adjacent to the pivot 7, as well as the two arms 8 of the body 2.
  • the ring 10 is used to easily detach the pin which can, moreover, be provided with a plummet thanks to a hole 11 which it presents.
  • the part of the handle 6 cooperating with the pivot 7 has two parts 12 forming a sort of fork between the arms of which are the arms 8 of the body 2. Between these two fork arms 12 is a middle arm 13 whose function will be explained below.
  • a piston 14 is mounted to slide in a bore of the body 2 of the plug.
  • This piston is integral with a metal tip 15 forming a striker, intended to pierce a metal membrane 16 hermetically closing a cartridge 17 containing an inert gas under pressure, nitrogen or carbon dioxide.
  • the cartridge 17 is screwed into a nozzle 18 itself screwed into a thread of the body 2.
  • the piston 14 has a thread, the reason for which will be explained below.
  • a pipe 22 is screwed by one of its ends into the body 2.
  • the handle 6 has a notch at 23, while the body 2 has a similar notch at 24.
  • An elastic plate, made of plastic for example, 25, is engaged by two opposite edges in the notches 23 and 24 when the members are located in the position shown in Figure 1. It may be, for example, a red colored plate indicating by its presence that the extinguisher is ready for use.
  • the part 13 ceases to cooperate with the piston 14 and the latter can return practically to its initial position, its stroke being limited by the contact of 13 and of the bottom 26 of a cut in the upper end of this piston.
  • the striker needle 15 is lowered into the position shown in phantom in Figure 2 and, therefore, has perforated the membrane 16 which closed the cartridge 17. From this moment, the gas under pressure in the cartridge flows into the container through the channel 27 and the tube 21. Therefore, a handle, not shown, disposed on the pipe 22, allows to project the extinguishing agent on the fire.
  • the handle 6 arriving in the working position according to FIG. 2 cannot be returned to the position according to FIG. 1 without the maneuvers which will be described.
  • a special key allows, by cooperation with these protrusions 31, to maneuver the ring 3.
  • the handle When the handle has returned to position according to FIG. 1, it only remains to put the safety pin 9 in place and to seal it and replace a new piece of signaling 25, so that the duly filled device is ready to operate again, a new cartridge 17 having obviously been put in place.
  • the fire extinguisher described has the advantage of not requiring any particular maneuver to ensure that it is put into working condition (perforation of the seal 16 and pressurization of the interior of the container 1) when necessary. In fact, in the event of a fire, it suffices to take the extinguisher by its handle (after having unlocked it) to transport it, to the place of the fire, by its handle held in the hand, so that automatically, under the effect of its own weight, so without special operation, the extinguisher is in working condition.
