Definitions

  • the invention relates to a device for operating a fire extinguisher. She more specifically aims to prevent fraudulent maneuver by a extinguisher.
  • the fire extinguishers known from the prior art can be of two types. They may include a constantly pressurized tank, then speaks of a permanent pressure extinguisher. They can also include a tank in which is mounted a cartridge of a gas propellant such as for example carbon dioxide and a striker maneuverable by means of a handle. When it is necessary to use the extinguisher, the handle moves a striker against a tinsel of the cartridge and it is perforated to release the propellant to inside the tank.
  • a gas propellant such as for example carbon dioxide
  • a fire extinguisher of the type described above is for example known from EP-A-0 507 664.
  • An indelicate or ill-intentioned user can thus empty the tank of the powder or liquid it contains, or even replace these produced by a flammable liquid, which can make the fire extinguisher particularly dangerous. It is also possible for a user imprudent to remove the propellant cartridge, for example to recover it for another use. It is therefore important for the safety of people and property to guarantee that a fire extinguisher whose pin has not been moved is in good working condition.
  • the invention achieves this goal by means of a simple device and economic. It relates to a device for operating a fire extinguisher type including a control system mounted on a tank and lockable by means of a pin and means for fixing the control system to the tank, characterized in that said pin is capable of preventing the operation of the fixing means.
  • the pin may include an extension which covers at least one of the nuts, so it is not possible to operate this nut when the pin is in place. If the system mounted on the tank by means of a ring, you can provide that this ring carries external grooves and that the pin includes an extension capable of engaging in one of the grooves of so that the ring is locked in rotation by a boss on which butte extension. According to a particularly advantageous variant of the invention, the device further comprises a displacement indicator of the pin out of its locking position. So if a user moved the pin to access the interior of the tank, this witness will be broken or distorted and an inspector or officer maintenance will easily detect this maneuver.
  • the fire extinguisher 1 in FIG. 1 comprises a metal tank 2 on which is fixed, by means of two nuts 3 and 3 ', a plate 4 supporting a control system.
  • the control system includes a handle 5 for transporting and operating the extinguisher, it comprises in addition to a cartridge 6 of propellant gas such as for example dioxide of carbon. Finally, it includes a dip tube 7, the lower end of which is immersed in a mass 8 of liquid extinguisher or powder.
  • a striker 12 is mounted integral with the handle 5 opposite a foil defining the upper part of the cartridge 6, so that a pressure on the handle 5 makes it possible to pierce the cartridge 6.
  • the downstream end of the tube 7 is connected to a flexible external conduit 9 and terminated by a handle 10 intended to be taken in hand by a user.
  • a pin 11 is inserted into the control system so as to keep the striker 12 away from the foil of the cartridge 6 in order to avoid any untimely perforation of the latter.
  • the pin 11 is extended outwards by a ring-shaped handle 11 a in which a user can pass one or more fingers to exert a pulling force in order to extract the pin from its housing, which makes it possible to release the striker and press it against the foil of the cartridge 6 using the handle 5.
  • the pin 11 is provided with an extension 11b which covers one of the nuts 3, so that it is not possible to maneuver this nut when the pin 11 is in place.
  • the pin is able to prevent the operation of the fixing means of the control system, formed by the elements mounted on the plate 4 on the tank.
  • the extension 11b here has a cap shape, but any form of the extension 11b which prevents the operation of at least one of the nuts 3 is adapted to fulfill the function of the invention.
  • the device further comprises an indicator of displacement of the pin from its locking position.
  • This is a link 14 around a fixed part of the control system such as for example the handle 5 and passing through the handle 11a of the pin 11.
  • This link 14 is provided with a lead 15 intended to break if the link 14 is subjected to a tensile force, which is the case that one tries to move the handle 11a of the pin 11 away from the handle 5 of the extinguisher.
  • the displacement indicator here is made of lead, but it could also be made of deformable plastic.
  • Figure 4 is a view similar to Figure 2 showing a second mode of the invention in which elements similar to those Figures 1 and 2 bear identical references increased by 50.
  • the fire extinguisher 51 of this embodiment differs from the previous embodiment essentially in that the plate 54 is circular and surrounded by a ring 70 intended to cooperate with an external thread surrounding the upper opening of the tank 52.
  • the handle 55 here is a rod shape with a rectangular section, but the invention applies to both embodiments whatever the shape of the handle.
  • the ring 70 is provided with external grooves 70 a , which facilitates its operation when it is tightened or loosened.
  • the handle 61 a of the pin 61 is, for its part, provided with two lugs 61 c and 61 d capable of engaging each in a groove 70 a of the ring 70.
  • a boss 71 is provided near the ring 70 so that, given its thickness, the lug 61 d driven during the loosening abuts against the boss 71 and that the rotation of the ring 70 and the plate 54 is thus prevented. It can be noted that the position of the pin 61 relative to the boss 71 is independent of the blocking characteristic insofar as the threading on the reservoir 70 is provided so that more than one turn of the ring 70 is necessary to loosen it .
  • the device also includes a pin displacement indicator.
  • This is a plastic tongue 72 fixed on the handle 61 a of the pin 61 and captive with a notch 73 formed in the handle 55.
  • the tongue 72 may be provided with an identification marking such than the year of the last check. If an operator exerts on the handle 61 has a pulling force to move the lugs 61 c and 61 d from the grooves 70 a, he exerts the same force on the tongue 72 which is then broken because it is trapped in the notch 73. To facilitate this rupture, provision can be made for the tongue 72 to be precut in its zone of maximum stress in the event of displacement. Thus, any attempt to access the interior of the reservoir 52 is detectable by the rupture of the tongue 72.
