Description

The Innovation concerns a fire extinguisher with a an extinguishing agent contained container and a propellant gas cartridge for filling of the container with propellant and an actuator to operate a resiliently biased valve pin, which with a plunger element to open the propellant gas cartridge for actuation a valve for releasing the acted upon by the propellant extinguishing agent is controllable. Furthermore, the innovation relates to an actuator for one such fire extinguishers.

Of the Innovation is the object of offering a fire extinguisher, in the case of use particularly quickly and easy to use. Furthermore, an actuating element for one such fire extinguishers Tobe offered.

These Task is for through the fire extinguisher the features of the protection claim 1 solved. Advantageous embodiments of the fire extinguisher in the subclaims 2 - 7 described. For the actuator the object is achieved by the features of the protection claim 8.

Of the Renewable fire extinguisher has a Actuator which has a first and a second area for actuation, the second area opposite increased in the first area is.

Of the Renewable fire extinguisher draws characterized by a specially shaped actuator, in which the actuating surfaces in at least two areas are divided, with these areas are located on different levels and the second area opposite to the increased first area is arranged.

At the Operating the fire extinguisher known per se in its other training must be before commissioning first a fuse element (locking pin) are removed. After that that must be actuator jerky actuated be to pressurize a known per se actuating mechanism one in the fire extinguisher attached To open propellant gas cartridge, causing the in the container of the fire extinguisher contained extinguishing agents is added with propellant gas.

To This "activation" of the fire extinguisher can the fire extinguisher be operated when the actuator is again pressurized by the user. When using the fire extinguisher then leaves the mixed with propellant extinguishing agent the fire extinguisher as long as the actuator depressed becomes.

All in all are thus in the use of the fire extinguisher two to each other determine separating steps. In a first step, the fire extinguisher is to be unlocked, by removing the locking pin. After that, in a second step - usually with a certain time interval - the fire extinguisher always then actuated Be if extinguishing agent supplied to the respective fire site shall be.

at fire extinguishers According to the state of the art, it can not be ruled out that the User after unlocking by pulling the locking pin the actuator in the pressed Stops position, which after the activation of the fire extinguisher immediate extinguishing agent the fire extinguisher leaves. This is in most cases not wanted.

Of the Renewable fire extinguishers now allows by the renewal proper training of actuating element a separation of the first step of the activation of the fire extinguisher and the second step of the operation of the fire extinguisher.

To has an advantageous embodiment the increased second area of the actuating element a partial area that serves as a printing area to the actual exercise of the actuating element and to the feeder of extinguishing agent serves. This results in a further subdivision of the second area, whereby the order of operation is clarified again to the user.

Further Details of the subject of the innovation will be apparent from the embodiments in the drawing figures. Show it:

1 a side view of the actuating element of the fire extinguisher,

2 a view A of 1 such as

3 a view B of 1 ,

From the drawing figures, the actuating element is clear, which in a known per se on a example of the DE 197 10 300 A1 well-known fire extinguisher is attached. This published patent application is incorporated with its entire disclosure content in this application, so that a further illustration of the operating mechanism, the fire extinguisher and other details of this disclosure can be taken.

The renewal proper actuator 1 has a first (area) area 2 and an increased (area) attached thereto area 3 , The actuator 1 is about an axis 4 pivotally mounted on the not shown fire extinguisher, through an opening 5 a known per se and not pictured valve pin to secure the actuator 1 and thus the fire extinguisher is pluggable.

When unlocking the fire extinguisher is first in a first step, the locking pin in the direction 6 (see. 3 ) from the actuator 1 pull it out. This act of "unlocking" the extinguisher is indicated by the inscription "1st pull" 3 on the first area 2 of the actuating element 1 clarified to the user.

In a second operation, the user can unlock the fire extinguisher the fist clenched hand on the second area 3 of the actuating element 1 which in the direction of 7 is pressurized, whereby in known manner, an opening of the propellant gas cartridge mounted in the extinguisher takes place and filled with extinguishing agent container of the fire extinguisher is filled with propellant gas.

This pressure-like application of force to the actuating element 1 in the area 3 is indicated to the user by the inscription "2." and the image of a hand clenched with an arrow symbolizing a pressurization.

After the actuator 1 now has been unlocked by the aforementioned two steps of the user can, in a subsequent and usually temporally complained step 3 by sustained pressurization of the actuator 1 in the area 3 in the direction 7 a pivoting of the actuating element 1 around the axis 4 in the direction 7 take place, whereby extinguishing agent exits the fire extinguisher.

This third step is indicated by the inscription "3. press "in one section 8th of the second area 3 of the actuating element 1 clarified. The subarea 8th is over a raised edge 9 opposite the subarea 10 of the second area 3 demarcated, as a baffle for activation of the actuator 1 serves.

Overall, the renewal modern fire extinguisher and the renewal proper actuator 1 the sequence of operations that can be performed by the user to unlock and operate a fire extinguisher.

For this purpose, the user is in particular for performing the second operating step of a jerky application of force of the actuating element 1 on the opposite of the first area 2 elevated second area 3 offered a baffle for performing the activation strike.

The renewal proper actuator 1 is characterized by a particularly user-friendly design.
