FR2624381A1 - Automatic-percussion fire extinguisher head with theft prevention effect - Google Patents

Abstract

The device for automatic percussion of the extinguisher is activated when the latter is moved from its storage location. At this moment, the pin, joined to the anchoring point by the chain, is torn off; it frees the point which, propelled by a spring, pierces the block closing the gas cartridge, thus freeing the latter. The theft prevention device, for its part, consists of a cap surrounding the head of the extinguisher, forming a barrier for the safety pin, so that for moving or holding the appliance without striking it, the key of the barrel lock is indispensable.

Description

 The present invention relates to a Fire Extinguisher Head with automatic percussion, with a deterrent effect against Theft.

 Currently, to put into operation a fire extinguisher, you have to unhook it (or move it), read the instructions for use tear off the safety pin and manually press a needle which moves, pierces a gas cartridge, which pro pulse the product contained in the body of the fire extinguisher.

 The device of the invention, it puts this needle in action, as soon as the device is off the hook or moved from its storage location.

 The percussion operation of the gas cartridge being automatic, it promotes the speed of fire fighting intervention, eliminates the anxiety of the user, by using his backup instinct, more than his reflection in a such a time.

 On the other hand, to combat theft, the head of the fire extinguisher is capped with an enveloping cover, which obstructs the percussion system as well as the safety pin; which means that any person other than the owner or the maintenance service of the extinguisher, who removes it from its support, has in its possession, a "crashed" device which will lose its propellant gas after several days .

 The device according to the invention will be better understood by referring to the figures.

 FIG. 1 represents the extinguisher as a whole, FIG. 2, the extinguisher in the "maintenance" position, FIG. 3, represents the extinguisher in the rest position (waiting for operation) and FIG. 4, the fire extinguisher in action.

 The fire extinguisher rests on its wall support (10). The chain te (1) makes the safety pin (2) integral with the support (10? Via the barrel lock (11).

 The wrap-around cover (12) which is screwed in allows the lance (13) and the safety pin (2) to pass on the other hand.

 For maintenance or routine checking of the device, the cylinder lock (11) is detached from the support (10) using its key. The extinguisher can thus be checked on site, without being struck.

 According to Figure 1, the fire extinguisher rests on its wall support (10). Your safety pin (2) keeps the needle (3) in the high position, the spring (4) is compressed in its housing.

 By pulling either the extinguisher (8), the chain (1) tightens, and tears off the safety pin (2); the needle (3) is propelled by the spring (4) which pierces with its hollow needle (5) the disc (6) obstructing the compressed gas cartridge (7), releasing the latter in the body of the extinguisher (8). The gas then acts as a propellant of the product to fight the fire; gasket (9), ensuring that gas does not escape through the needle housing (3), the time of use.

 The force of the spring (4) is such that the hollow needle (5) of the needle (3) can perforate the disc (6) of the gas cartridge (7).

Claims (3)

RErEDICATIOS 1.Automatic percussion device of a fire extinguisher characterized in that it comprises a spring (4) kept compressed in its housing under the action of a safety pin (2) secured by means of a chain (1), with a solid anchoring point, the mass of which resists the force caused when the pin (2) is torn off, and allowing the spring (4) to relax at this time in order to release the needle (3) which punctures the pellet (6), via the needle (5) of the gas cartridge (7). 2. Device according to claim 1 characterized in that it comprises a rigid cover (12) enveloping the head of the extinguisher, allowing only the product lance (13) and the safety pin (2) to pass through. uprooting. 3. Device according to claim 1 characterized in that it comprises a barrel lock (11) connected, on the one hand to the wall support (10) and, on the other hand, to the safety pin (2) by l 'Intermediate of a chain (1), allowing authorized persons, to remove the extinguisher, without putting it into operation.
