Definitions

  • the invention relates to a fire extinguisher with an inside Extinguishing agent container housed compressed gas container, which with a on the Extinguishing agent container seated tapping fitting is connected, via which means a safety element to be actuated in particular by hand Sealing element of the compressed gas tank piercing bolt is actuated.
  • the tap fitting For most types of fire extinguishers, it is common to use one for the tap fitting to provide the appropriate impact button.
  • a fire extinguisher is for example known from EP-A 0 867 205.
  • the strike button is located centrally in the upper part of the apex of the piercing fitting and on the Extinguishing agent container cover hood. This button can be used with a clenched fist to be pushed down, causing the compressed gas tank is opened via a mandrel or the like and the fire extinguisher in Readiness for deletion is set.
  • the extinguishing agent is applied via a Riser pipe, which leads out of the extinguishing agent container and to a hose is connected, at the free end of which there is an extinguishing gun.
  • Fire extinguishers have also been proposed, one of which Operating steps are no longer required.
  • a fire extinguisher is known, which is designed so that the Sealing element on the pressurized gas container by swiveling the mandrel Extinguishing hose is pressed into its working position.
  • the Extinguishing hose connected and pivotable between two end positions Connection piece provided, which is provided with a lever, which at one Swiveling the connection piece from the rest position into the working position the bolt penetrating the sealing element indirectly or directly depresses.
  • EP-B 0 504 664 relates to a fire extinguisher of the type mentioned at the outset thus no impact button, but has a locking pin, which in one Cladding covering the fire extinguisher head is housed and can be pulled up out of the panel by sliding.
  • It mechanical connection means are arranged in the interior of the cladding the movement of the pin on a firing pin to open the Transfer compressed gas tank.
  • These connecting means comprise one swiveling lever and a pin for the arranged in the distributor head Firing pin.
  • the lever is on one side on an arm of the actuating pin and on the other hand on the firing pin. A strong pull on the actuating pin thus causes the lever to pivot and Acting on the bolt to pierce the sealing element on Compressed gas tank.
  • the effort required for this solution should also be sufficient for weaker people are too big.
  • the invention has now set itself the task of a fire extinguisher at the beginning mentioned type, which accordingly by pressing a securing element in Readiness to extinguish is to be designed in such a way that to operate the Securing element only a small amount of force is necessary.
  • the fire extinguisher It should therefore be comparatively easy to operate even for weaker people can be taken.
  • a mechanical simple structure that ensures extremely reliable operation, be given.
  • the object is achieved according to the invention in that Removing the securing element of the bolt automatically in one movement Puncturing the sealing element on the pressurized gas container is displaced.
  • the energy that arises on the bolt Puncturing the sealing element acts from an energy store.
  • the energy storage device has at least one spring, by means of which the bolt counteracts the securing element is biased.
  • the configuration is also particularly simple and expedient in that the securing element itself the bolt in a position with a preloaded spring holds.
  • the securing element with a securing pin be provided, which holes on the housing of the valve and on the bolt enforced.
  • the measure of providing a helical spring in particular as a spring one end is armature-proof and the other is supported on the bolt, contributes to Simplicity and reliability.
  • the Sealing element of the compressed gas container penetrating part of the bolt as a the hollow bolt connected to the bolt can be made by lateral Passages on the mandrel and the pin of the gas exit from the Container is guaranteed.
  • the locking pin only needs to be actuated by hand on its outer surface End area be provided with a tab, eyelet or the like.
  • FIG. 1 is a cross section through part of the upper region a fire extinguisher designed according to the invention and Fig. 1a a Sectional view along the line I-I of FIG. 1st
  • the fire extinguisher not shown in full in FIG. 1 includes one Extinguishing agent container 1, which is substantially hollow cylindrical, and both in the upper and in the lower area due to dome-shaped connecting parts, of which only the upper connection part 1a is shown, is closed.
  • the upper connection part 1a is through with the extinguishing agent container, for example Screwed together and holds a fitting 3, which is described in more detail below is described on the fire extinguisher.
  • a compressed gas container 2 is arranged inside the extinguishing agent container 1, which is flanged to an inner housing part 3b of the valve 3.
  • the Compressed gas container 2 is with a propellant under high pressure, For example, carbonic acid, filled and with an upper end Sealing element 4 closed, which for commissioning the extinguisher by a Thorn 5 is to be pierced. This gets it out of the compressed gas container 2 released propellant via a blow pipe 6, which down to the bottom in the extinguishing agent container 1 protrudes into the interior of the extinguishing agent container 1, where the Extinguishing agent is whirled up by the gas or put under pressure.
  • a propellant under high pressure For example, carbonic acid
  • the output of the extinguishing agent takes place via a riser pipe 7, the opening of which is close to the Bottom of the container and through which the extinguishing agent is conveyed upwards becomes.
  • a hose can now be used here in a known and not shown manner be connected, at the free end of which there is an extinguishing gun.
  • the housed in the upper connector 1a and with the pressurized gas container 2 in Connected armature 3 comprises an outer housing part 3a and already mentioned inner housing part 3b, on which, as explained above, the Pressurized gas container 2 is flanged.
  • the outer housing part 3a takes the inner Housing part 3b largely and surrounds this.
  • the two-part version allows the fitting 3 to be assembled and accommodated inside arranged further components.
  • An essential part of the armature 3 is a Armature 3 bolt passing through from above in the direction of compressed gas container 2 8, which in the illustrated embodiment ends at one end of the armature 3 protrudes and can be provided with a handle for the fire extinguisher.
  • the bolt 8 is displaceably arranged with respect to the fitting 3 and takes on the second end of the mandrel 5, which is designed here as a hollow pin.
  • FIG. 1a shows a section through the bolt 8 with the mandrel 5 fastened in it
  • the Mandrel 5 has a passage opening 9 passing through the mandrel wall, which is here Is longitudinal slot and a lateral outflow of the blowing agent after the Piercing the sealing element 4 outwards into the small cavity 13, where that Blow pipe 6 opens with its upper end, allowed.
  • the longitudinal slot can also provide holes, possibly also extending through the bolt 8 become.
  • the bolt 8 is in the position shown in FIG. 1 before start-up by a spring 10 against a locking pin 11a of a locking element 11 biased.
  • the spring 10 is a in the illustrated embodiment Helical compression spring, which is in a further, both from the inner and from the outer housing part 3a, 3b formed cavity 14 is housed, the Surrounds bolt 8 and one end at a fixedly connected to the bolt 8, disk-shaped abutment 8a and elsewhere on the upper floor of the cavity 14, which is formed by the outer housing part 3a, is supported.
  • the cavity 14 is designed in a length that largely relaxes the spring 10 allowed.
  • the spring 10 In the unactuated position of the fire extinguisher, the spring 10 is by the Locking pin 11a held.
  • the pin 11a is through a bore 12 in the upper Housing part 3a and at the same time through a corresponding bore 8b in Bolt 8 inserted, whose position in the bolt 8 ensures that the spring 10 under correspondingly strong preload.
  • the securing element 11 is now removed by pulling on the tab 11b, the bolt 8, which is under strong spring force, snaps down and the mandrel 5 pierces the sealing element 4 of the compressed gas container 2.
  • the pull out the force of the securing element 11 is significantly less than that of the Compression spring 10 force exerted on the bolt 8.
  • the Interpretation should be such that when the by the preloaded compression spring 10 applied force is approximately 200 Newtons, the force to remove the Lock pin 11a could be around a tenth of this value.
  • the force required to pull the securing element 11 can therefore be at subject invention have a size that is unintended and too easy loosening prevents, but also allows weaker people in in a stressful situation, the fire extinguisher can be put into operation quickly and safely can.
  • biasing means for the bolt 8 can be considered appropriately trained and housed leaf springs or torsion springs his. Instead of one coil spring, several concentric or juxtaposed springs are provided.
  • other energy storage devices can also be built into the valve, For example, a small, pressurized gas cartridge that is pulled of the securing element is opened so that the bolt in its movement to Piercing the sealing element of the compressed gas container is offset.
  • the securing element with the Bracket for example a wall bracket, connected to the fire extinguisher is that simply by removing the fire extinguisher the securing element is already removed.
