Abstract

The fire extinguisher (100) has a common container (10) to hold extinguishing medium (12) and propellant (11) and a device (13) for manual operation. A first riser pipe (17), for discharging the extinguishing medium, extends from the control device to near the floor (18) of the container. The extinguisher has a device, which may be a sprinkler head or a valve (20) with a fuse, which releases the extinguishing medium under the action of heat, and which is connected to a similar riser pipe (23). The device for manual operation is a hand-operated valve, which has a spray head (14) and a handle (15), which is combined with a control lever (16).

Description

The invention relates to a continuous pressure hand-held fire extinguisher in which the extinguishing agent and propellants are in a common container and which has a device for manual actuation, a Riser pipe for conveying the extinguishing agent inside the container from the device for manual operation almost to the bottom of the Container is sufficient.

Handheld fire extinguishers are portable fire extinguishers that come with different Extinguishing media, such as water, foam, powder or carbon dioxide are and primarily for fighting small and emerging fires are suitable. Basically there is between two types of hand extinguishers to distinguish.

Continuous pressure hand-held fire extinguishers are fire extinguishers that use extinguishing agents and propellants are located in a common container that can pass through the blowing agent is under pressure. Due to the overpressure or the blowing agent the extinguishing agent is pressed out when a hand lever fitting is actuated.

In a hand-held fire extinguisher, the propellant is separate from the Extinguishing media arranged. The propellant is either in a gas cartridge inside the fire extinguisher or in a gas bottle on Fire extinguisher or the extinguishing agent container is attached. The in Extinguishing agent container arranged gas cartridge is from the outside by a Impact button or a lever mechanism when the Hand lever armature opened so that the propellant extinguishes the extinguishing agent can drive. If the propellant bottle is located on the outside, so is this via a connecting pipe to the interior of the extinguishing agent container connected. By opening the gas bottle using a valve or also by pressing a push button, the gas escapes into the Extinguishing container and generates overpressure that can be driven.

Disadvantageously, manual fire extinguishers can only be operated manually, so that in the event of fires where no people were present, useless burned up at their locations.

Automatic extinguishing devices such as sprinkler systems and. The like. Known, however, in the case of genesis fires by people before Location can be extinguished, causing greater damage than the fire.

It is therefore an object of the invention, generic continuous pressure fire extinguishers to improve such that a deletion process is also automatic can be initiated.

This object is solved by the features of claim 1.

For this purpose, a continuous pressure hand-held fire extinguisher is provided according to the invention to create that has means that are exposed to great heat or direct flame contact automatically release the extinguishing agent.

Sprinkler heads are a means of triggering the automatic extinguishing process or other valves secured by fuses that with the pressurized interior of the continuous pressure fire extinguisher with the extinguishing and propellant in connection.

The agent can be at any height of the container of the continuous pressure fire extinguisher be attached, provided it is guaranteed that an inside connected riser to the bottom of the container there the extinguishing agent under propellant pressure for spraying record, or that the extinguishing agent can leak directly.

Conventional continuous pressure hand-held fire extinguishers can also be used in accordance with the invention be retrofitted. You can either use an existing manometer be exchanged for a corresponding means or between the hand lever fitting and the container becomes a T-shaped adapter arranged, which has an agent that when exposed to heat or The flame will automatically release the extinguishing agent. In a preferred one Embodiment, the adapter is also over the full Length of the riser pipe pushed so that two pushed into each other Riser pipes result. This embodiment has the advantage that conventional Continuous pressure hand-held fire extinguisher by installing an adapter can be converted.

It is also possible to use conventional handheld fire extinguishers without using further conversions only by replacing the manometer with one to retrofit appropriate means. With some types of fire extinguishers plus the previous opening, which only leads the propellant to the manometer be sealed. In order to achieve a possibly higher output, can expand the remaining inner bore to overpressure.

Only when retrofitting or retrofitting conventional hand-held fire extinguishers It is not possible to install a pressure gauge at the pressure gauge connection. Otherwise pressure gauges can be used without any problems.

The invention advantageously ensures that continuous pressure hand-held fire extinguishers in a fire where no people are present are no longer just glowing useless to their point of view, but at least extinguish in their environment, being a manual operation is of course also possible, even if the device is previously on its Automatic was triggered as far as there is still extinguishing agent in the container.

Further advantageous refinements are characterized in the subclaims.

The invention is explained in more detail below with reference to drawings. They show in a purely schematic representation

1 to 8

in cut or partially cut side views of the continuous pressure hand-held fire extinguisher according to the invention in various embodiments.

The continuous pressure hand-held fire extinguishers 100-800 have a container 10, which is filled with a propellant 11 and an extinguishing agent 12. For manual Actuation, the container 10 has a hand lever fitting 13, the a spray head 14 and a handle 15 with an operating lever 16 is combined. The hand lever armature 13 has a Riser pipe 17, which extends approximately to the bottom 18 of the container 10 and through which the extinguishing agent 12 is driven out. Below the Hand lever armature 13 is indicated a pressure gauge connection 13a, in the a manometer, not shown, can be screwed in.

1 and 2 show a continuous pressure fire extinguisher 100, 200, the via a sprinkler head 19 or a valve 20 with a fuse (fire trace) has, which or in each case in the region 21 of the wall 22nd of the container 10 is arranged in which is usually the propellant 11 is located. The sprinkler head 19 and the valve 20 also have via a riser pipe 23 which extends approximately to the bottom 18 of the container 10 enough and through which the extinguishing agent 12 in an automatic extinguishing process is promoted.

In the continuous pressure hand-held fire extinguisher 300, 400 according to FIGS. 3 and 4 the sprinkler head 19 or the valve 20 in the area 24 of the bottom 18 of the Container 10 arranged so that the extinguishing agent 12 in an automatic Triggering can be driven out without a riser.

The continuous pressure handheld fire extinguishers 500, 600 of FIGS. 5 and 6 usually have a manometer on through the wall 22 of the hand lever fitting 13 is connected to the riser pipe 17 and here by Sprinkler head 19 or the valve 20 is replaced. The extinguishing agent 12 will therefore also via the riser pipe 17, which leads to the hand lever fitting 13 led to the sprinkler head 19 or the valve 20.

Another option is the usual continuous pressure fire extinguisher 700, 800 Retrofitting according to the invention is shown in FIGS. 7 and 8. For this is a preferably T-shaped adapter 25 between the container 10 and the hand lever fitting 13, to which a sprinkler head 19 or a valve 20 is connected and the adapter 25 in the container 10 extends into and with one end 26 completely over the Riser pipe 17 of the hand lever fitting 13 is pushed so that a second Riser tube 27 is formed by the adapter 25 through which the Extinguishing agent 12 is supplied to the sprinkler head 19 or the valve 20.
