Definitions
- the invention lies in the technical field of fire extinguishers and more specifically relates to a new fire extinguisher head with a anti-rearming safety and allowing the visualization of the device for blocking said mechanism.
- the extinguishers used so far are as we know essentially consist of a tank provided at the top of an opening on which a head is fixed dispensing agent.
- the head which is a part from foundry or machining or molding is provided with a through-hole which supports a tube plunger extending to the base of the tank, well which communicates with a flexible connection to a blow gun equipped with a spray cane or nozzle.
- the head also supports a closed gas cartridge under pressure, sustained inside the tank, which can be communication with the interior of said tank after action of a striker on a stopper of the hole in the cartridge.
- a known percussion system of cartridges is described in EP-0 274 452.
- the striker and the connecting conduits are housed in the actual distribution head maintained in place on the tank by a fixing nut or other system.
- Known fire extinguishers are also equipped with a grip handle and presser lever with which the user can by pressing strongly, act on the spray head striker. This operation is not made possible only if he previously shot a locking pin of said presser lever.
- the invention therefore relates to a head anti-rearm safety extinguisher, comprising a pressurized gas tank and cartridge for the evacuation of the extinguishing agent through said head, as well as a pressure lever acting on a striker, and released by a control ring tearing towards the high, and comprising a blocking pin for immobilization of the striker, head according to which the blocking pin is housed in an opening of said head and is itself locked in this position by the control ring, the end of the pawn allowing the visualization of the state of arming the device.
- the striker is hollowed out with a circular groove whose triangular profile corresponds to the conical profile from one end of the blocking pin.
- the pawn of blocking has a lower annular central part diameter than the neighboring parts of the pawn and which corresponds at the spacing of two rods carried by the ring of ordered.
- the end of the blocking pin on the side opposite the profiled end, has one side colored and this colored end is erased in the opening and is not visible to a user when the presser lever is not actuated.
- Figure 1 shows a dispensing head 1 intended to be tightly fixed on the orifice upper side of a fire extinguisher tank 2.
- the head is provided with a through-hole 3 communicating with the interior of the tank, whose orifice upper 4 allows connection to a hose or nozzle not shown.
- a presser lever 6 On the head of distribution 1 which is a part coming from foundry or machining or molding, revolves around an axis 5, a presser lever 6. A flat 7 of said lever near the axis 5 bears against the rounded head 8 of a striker 9. The latter can slide inside a vertical sleeve 10 on which a cartridge is fixed 11 gas under pressure. The sleeve communicates by a duct not shown with the interior of the tank 2.
- the striker 9 is shown in more detail in the figure 2. It has a generally cylindrical shape and four sides cut 12 are provided on the sides of its rounded head 8.
- the striker is hollowed out a profiled circular groove 13 with a triangular profile whose role will appear below.
- Down another throat circular 14 serves as housing for an O-ring 15 allowing sealed movement of the striker in the sleeve 10.
- a flange 16 surrounding the base of the striker 9 limits its travel in the sleeve, in which is provided for this purpose a shoulder 17.
- Finally the striker 9 is hollowed out at its base, axially, and over part of its height of a cell 18 in which a punch pin 19.
- the horizontal opening 21 serves as a housing for a blocking pin 26 shown in isolation in Figure 4. It is a small cylindrical part whose central part ring 27 is of smaller diameter than that of neighboring parts of the pawn.
- One end 28 (right on the figure) has a colored side.
- the opposite end 29 shows a conical profile to the dimensions of the profiled groove 13 of striker 9.
- the annular central part 27 is offset relative to well 22 and therefore it is impossible replace the control ring 23 even if you have reassemble the lever 6. In any case, the striker remains in low position and the device can no longer be reset without repositioning of the striker which would require opening the fire extinguisher.
- the anti-rearmament safety mechanism as well described therefore allows immediate visualization of its state armed device ready for use or device already in use.
