Description

Die Erfindung betrifft eine Vorrichtung zur Ankopplung eines Lungenautomaten an einen Atemanschluß mit zumindest einer verschließbaren Umgebungsluftansaugöffnung und einem Freigabeschalter für ein Flaschenluftzuführventil am Lungenautomaten.The invention relates to a device for coupling of a regulator to at least one breathing connection a closable ambient air intake and a release switch for a bottle air supply valve at the regulator.

Als Atemanschlüsse gelten zum Beispiel Schutzanzüge oder Atemschutzmasken wie Vollmasken, Halbmasken oder Atemschutzhauben. Sie werden über einen Lungenautomaten mit einer Luftversorgung, zum Beispiel einer Atemluftflasche, einem Gebläse etc. verbunden. Derartiges, sogenanntes schweres Atemschutzgerät, wird beispielsweise von Feuerwehrleuten in Brandsituationen eingesetzt, wo die Umgebungsluft giftige Gase, Rauch etc. enthält.Protective suits, for example, are considered breathing connections or respirators such as full face masks, half masks or Respirators. You will have a regulator with an air supply, for example a breathing air bottle, connected to a blower, etc. Such, so-called heavy breathing apparatus, for example used by firefighters in fire situations where the ambient air contains toxic gases, smoke, etc.

Dabei ist es bisher bekannt, eine Atemluftflasche und eine Atemschutzmaske anzulegen, den Lungenautomaten zum Anschluß der Maske an die Flasche aber erst an dem eigentlichen Einsatzort an die Atemschutzmaske anzukoppeln. Bis dahin wird an der Ansaugöffnung der Atemschutzmaske Luft aus der Umgebung eingeatmet. Beim Ankoppeln des Lungenautomaten wird dann in diese Ansaugöffnung ein an dem Lungenautomaten befindlicher Anschlußstutzen eingesetzt, wobei gleichzeitig im Lungenautomaten ein Flaschenluftzuführventil freigegeben wird, so daß über dieses Ventil im Lungenautomaten bedarfsgerecht Flaschenluft in die Atemschutzmaske fließen kann (siehe z.B. EP-A-0 394 139). So far it is known to be a breathing air bottle and to put on a respirator, the regulator to Connection of the mask to the bottle but only on the to couple the actual place of use to the respirator. Until then, the breathing mask will be on the suction opening Air inhaled from the environment. When coupling of the regulator is then in this suction opening a connector located on the regulator used, at the same time in the regulator a bottle air supply valve released is so that this valve in demand valve Flow bottle air into the respirator can (see e.g. EP-A-0 394 139).

Ein wesentlicher Nachteil dieser bekannten Vorrichtung liegt darin, daß es im entscheidenden Augenblick Zeit benötigt und damit zu lange dauern kann, bis der Anschlußstutzen des Lungenautomaten in die Ansaugöffnung der Atemschutzmaske eingesetzt und damit das Atmen von Umgebungsluft auf Flaschenluft umgestellt ist.A major disadvantage of this known device is that there is time at the crucial moment needed and can therefore take too long until the connecting piece the regulator into the suction opening the respirator and thus breathing from Ambient air is switched to cylinder air.

Aufgabe der vorliegenden Erfindung ist es daher, eine bekannte Vorrichtung so weiterzubilden, daß dieses Umstellen in kürzester Zeit und ohne umständliches Hantieren durchgeführt werden kann.The object of the present invention is therefore a further develop known device so that this change in the shortest possible time and without cumbersome handling can be carried out.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Ankoppelvorrichtung für den Lungenautomaten an den Atemanschluß ein Stellglied aufweist, das bei an dem Atemanschluß befestigtem Lungenautomaten manuell verstellbar ist zwischen einer ersten Position, in der die Umgebungsluftansaugöffnung verschlossen und gleichzeitig das Flaschenluftzuführventil freigegeben ist, und einer zweiten Position, in der die Umgebungsluftansaugöffnung geöffnet und gleichzeitig das Flaschenluftzuführventil insbesondere in seiner Geschlossenstellung gesperrt ist.This object is achieved in that the coupling device for the regulator to the Breathing connection has an actuator, which at the Manually adjustable attached breathing regulator is between a first position in which the Ambient air intake is closed and at the same time the bottle air supply valve is released, and a second position, in which the ambient air intake opening opened and at the same time the bottle air supply valve especially in its closed position Is blocked.

Diese Erfindung hat den Vorteil, daß ein Maskenträger den Lungenautomaten bereits beim Anlegen des Atemschutzgerätes an seine Atemschutzmaske ankoppeln kann, ohne daß bereits Flaschenluft in die Atemschutzmaske fließt. Der Maskenträger kann also wie bisher sich dem eigentlichen Einsatzort nähern und dabei immer noch Umgebungsluft atmen um so seinen Flaschenluftvorrat zu schonen, und erst am Einsatzort mit einer kurzen manuellen Betätigung eines Stellgliedes seine Atemluft von Umgebungsluft auf Flaschenluft umstellen. Dies ist erheblich schneller und einfacher als das umständliche, zeitraubende Einführen des Lungenautomaten mit seinem Anschlußstutzen in die Ansaugöffnung, wie dies bisher geschah.This invention has the advantage that a mask carrier the regulators already when putting on the breathing apparatus can connect to his respirator, without bottle air already in the respirator flows. The mask wearer can do as before Approach the actual place of use and still have ambient air breathe so his bottle air supply gentle, and only at the place of use with a short manual Actuation of an actuator removes his breathing air Switch ambient air to bottle air. This is significant faster and easier than the cumbersome time-consuming insertion of the regulator with its Connection piece in the suction opening, as previously happened.

Auch das Zurückschalten auf Umgebungsluft kann so schnell und problemlos erfolgen, da auch hierfür nur das Stellglied in die andere Position zurückgebracht werden muß, bei der die Umgebungsluftansaugöffnung geöffnet ist und gleichzeitig das Flaschenluftzuführventil in seiner Geschlossenstellung gesperrt ist.Switching back to ambient air can also do this done quickly and easily, because only for this the actuator is returned to the other position must be opened at which the ambient air intake and at the same time the bottle air supply valve is locked in its closed position.

Die Verstellung des Stellgliedes kann sowohl über eine Dreh- oder eine Schwenkbewegung erfolgen, bei einer bevorzugten Ausführungsform ist das Stellglied aber direkt durch den Anschlußstutzen für den Lungenautomaten gebildet und insbesondere über eine Verschiebung des Lungenautomaten betätigbar. Das heißt, daß mit einem einfachen Druck von vorne auf den Lungenautomaten das Stellglied bestätigtwird und die Luftzufuhr umschaltet, während bei einem anschließenden Zug am Lungenautomaten zurückgeschaltet wird. Damit die Umschaltung von dem einen in den anderen Zustand nicht ungewollt passiert, ist es vorteilhaft, wenn das Stellglied in den zwei Endpositionen einrastbar ist, so daß bei seiner Betätigung ein kleiner Anfangswiderstand zu überbrücken ist.The adjustment of the actuator can be done via a Rotary or pivotal movement occur in a preferred Embodiment is the actuator directly through the connector for the regulator formed and in particular through a shift of the regulator can be operated. That means that with a simple push from the front onto the regulators the actuator is confirmed and the air supply is switched, while on a subsequent train on Regulator is switched back. So the switchover not from one state to another happens unintentionally, it is advantageous if the actuator can be locked in the two end positions, so that a small initial resistance when actuated is bridged.

Insbesondere in der Position, in der durch das Stellglied die Umgebungsluftansaugöffnung verschlossen und gleichzeitig das Flaschenluftzuführventil freigegeben wird, kann bei einer bevorzugten Ausführungsform das Stellglied selbsttätig arretieren. Damit ist gewährleistet, daß in einer Situation, in der das Einatmen von Umgebungsluft aufgrund der in ihr enthaltenen Gase schädlich wäre, ein versehentliches Zurückschalten des Stellgliedes verhindert wird.Especially in the position in which the actuator the ambient air intake is closed and at the same time the bottle air supply valve is released in a preferred embodiment, the Lock the actuator automatically. This ensures that in a situation where inhalation of Ambient air due to the gases it contains would be harmful, an accidental switching back of the Actuator is prevented.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles gemäß den beigefügten Zeichnungen. Dabei zeigt

Further advantages and features of the invention result from the following description of an exemplary embodiment according to the accompanying drawings. It shows
Figure 1
a coupling device according to the invention with open ambient air intake opening and blocked bottle air supply valve;
Figure 2
a coupling device according to the invention with closed ambient air intake opening and released bottle air supply valve.

Figur 1 zeigt einen Lungenautomaten 1, der an eine Atemschutzmaske 2 angekoppelt ist. Bei der Atemschutzmaske ist in einen Maskenkörper 3 ein Sichtfenster 4 eingesetzt. Außerdem ist mit dem Maskenkörper 3 ein Ankoppelelement 5 dicht verbunden. Hierzu wird das Ankoppelelement 5, das mit einem Außengewinde versehen ist, in ein am Maskenkörper 2 befindliches korrespondierendes Gewinde eingeschraubt. Im Ankoppelelement 5 ist ein Anschlußstutzen 6 des Lungenautomaten 1 verschiebbar.Figure 1 shows a regulator 1 which is connected to a Respiratory mask 2 is coupled. With the breathing mask is a viewing window 4 in a mask body 3 used. In addition, there is a coupling element with the mask body 3 5 tightly connected. For this purpose, the coupling element 5, which is provided with an external thread, into a corresponding one located on the mask body 2 Screwed thread. In the coupling element 5 is a Connection piece 6 of the regulator 1 can be moved.

Dabei kann der Anschlußstutzen 6 mit einem vorgespannten Element 7 in Rastnuten 8, 9, die im Ankoppelelement 5 ausgebildet sind, einrasten. Zwischen dem Ankoppelelement 5 und dem Anschlußstutzen 6 ist außerdem eine Ringdichtung 10 vorgesehen, die verhindert, daß Nebenluft durch den zwischen Ankoppelelement 5 und Anschlußstutzen 6 gebildeten Spalt hindurchgezogen wird.The connecting piece 6 can be biased with a Element 7 in locking grooves 8, 9 in the coupling element 5 are formed, snap into place. Between the coupling element 5 and the connector 6 is also an annular seal 10 is provided, which prevents Secondary air through the between coupling element 5 and connecting piece 6 formed gap is pulled through.

In seinem außerhalb des Ankoppelelementes 5 liegenden Bereiches weist der Anschlußstutzen 6 mehrere über seinen Umfang verteilte Umgebungsluftansaugöffnungen 11 auf, durch die wenn der Maskenträger einatmet entsprechend den Pfeilen 12 Umgebungsluft in das Maskeninnere strömen kann. An seinem dem Ankoppelelement 5 abgewandten Ende trägt der Anschlußstutzen 6 den Lungenautomaten 1, mit dem ein Flaschenluftzuführventil 13 betätigbar ist. In der Figur 1 ist dieses Ventil in der geschlossenen Stellung dargestellt. Es verschließt die Leitung 14, die zu einer Atemluftflasche führt.In its outside of the coupling element 5 Area has the connecting piece 6 several ambient air intake openings 11 distributed around its circumference on through when the mask wearer inhales accordingly arrows 12 ambient air into the mask interior can flow. On its facing away from the coupling element 5 End of the connection piece 6 carries the regulator 1, with which a bottle air supply valve 13 can be actuated is. In Figure 1, this valve is in the closed Position shown. It closes the Line 14, which leads to a breathing air bottle.

Das Flaschenluftzuführventil ist über ein Gestänge 15 mit einer beweglichen Atemmembran 16 verbunden. Dabei ist das Gestänge 15 an einem Kipphebel 17 angelenkt, der mit einem aus dem Gehäuse des Lungenautomaten nach außen geführten Freigabeschalter 18 verbunden ist.The bottle air supply valve is via a linkage 15 connected to a movable breathing membrane 16. Here the linkage 15 is articulated on a rocker arm 17, the one with from the housing of the regulator externally guided release switch 18 is connected.

Dieser Freigabeschalter 18 bringt, wenn er wie in Figur 1 dargestellt, nicht betätigt ist, den Kipphebel 17 in eine Position, die das Flaschenluftzuführventil in seiner Geschlossenstellung sperrt.This release switch 18 brings when it as in Figure 1, is not actuated, the rocker arm 17 in a position that the bottle air supply valve is in locks its closed position.

In der Figur 2 ist der Anschlußstutzen 6 in das Ankoppelelement 5 des Maskenkörpers 3 eingefahren, bis es mit dem vorgespannten Element 7 in die weiter innen liegende Rastnut 8 einrastet. Das dem Lungenautomaten 1 zugewandte Ende des Ankoppelelementes 5 dichtet dabei im Zusammenwirken mit einer zweiten Ringdichtung 19 die Umgebungsluftansaugöffnungen 11 ab. Dabei wird gleichzeitig mit einem an dem Ankoppelelement 5 ausgebildeten Bund 20 der Freigabeschalter 18 betätigt. Dadurch kippt der Kipphebel 17 in eine Position, in der das Flaschenluftzuführventil 13 über das Gestänge 15 durch die Atemmembran 16 betätigt werden kann: Wenn der Maskenträger einatmet, entsteht in dem Raum, der in der Figur 2 links von der Atemmembran 16 dargestellt ist, ein Unterdruck, dem die Membran 16 folgt. Dabei wird über das Gestänge 15 das Flaschenluftzuführventil 13 nach unten bewegt und öffnet damit die Leitung 14, so daß Flaschenluft entsprechend den Pfeilen 21 zum Maskenträger strömen kann. Atmet der Maskenträger aus, so wird der Unterdruck abgebaut und die Atemmembran 16 beweqt sich wieder in ihre Ursprungsposition zurück, wobei das Ventil 13 geschlossen und so nicht unnötig Flaschenluft verbraucht wird.In Figure 2, the connector 6 is in the coupling element 5 of the mask body 3 retracted until it with the prestressed element 7 in the further inside horizontal locking groove 8 engages. The regulator 1 facing end of the coupling element 5 seals in cooperation with a second ring seal 19 Ambient air intake openings 11. Doing so simultaneously with a trained on the coupling element 5 Bund 20 of the release switch 18 is actuated. This tilts the rocker arm 17 to a position in which the bottle air supply valve 13 on the linkage 15 through the Breathing membrane 16 can be operated: If the mask wearer inhales, arises in the space in the figure 2 is shown to the left of the breathing membrane 16 Vacuum, which the membrane 16 follows. It is about the linkage 15 after the bottle air supply valve 13 moves below and thus opens the line 14, so that Bottle air according to the arrows 21 to the mask wearer can flow. If the mask wearer exhales, then the negative pressure is released and the breathing membrane 16 is moved back to their original position, whereby the Valve 13 closed and so unnecessary bottle air is consumed.

Beim Einschieben des Anschlußstutzens 6 in das Ankoppelelement 5 greift ein Arretierungshaken 22 hinter den Bund 20 des Ankoppelelementes.When inserting the connecting piece 6 into the coupling element 5 engages a locking hook 22 behind the Bund 20 of the coupling element.

Zusammenfassend funktioniert die dargestellte Vorrichtung wie folgt: Nachdem der Maskenträger die Atemschutzmaske 2 aufgesetzt hat, führt er den über die Leitung 14 an eine Atemluftflasche angeschlossenen Lungenautomaten 1 mit dessen Anschlußstutzen 6 in das Ankoppelelement 5 der Atemmaske ein, das mit einem Gewinde in den Maskenkörper 2 eingeschraubt ist. Der Anschlußstutzen rastet in der ersten Rastnut 9 ein. In dieser Position kann Umgebungsluft durch die Umgebungsluftansaugöffnungen 11 in die Atemmaske strömen, wenn der Maskenträger einatmet. In summary, the device shown works as follows: After the mask wearer the breathing mask 2 has put on, he leads over the Line 14 connected to a breathing air bottle Regulators 1 with its connecting piece 6 in the Coupling element 5 of the breathing mask with a thread is screwed into the mask body 2. The connecting piece engages in the first locking groove 9. In This position allows ambient air through the ambient air intake openings 11 pour into the breathing mask if the mask wearer inhales.

Bei Erreichen seines eigentlichen Einsatzortes schiebt der Maskenträger den Lungenautomaten 1 mit seinem Anschlußstutzen 6 ganz bis zum Einrasten in die Rastnut 8 in das Ankoppelelement 5, wobei einerseits die Umgebungsluftansaugöffnungen 11 verschlossen werden und gleichzeitig der Freigabeschalter 18 betätigt wird, mit dem das Flaschenluftzuführventil 13 zum Atmen freigegeben wird. Damit der Lungenautomat sich nicht ungewollt wieder aus dieser Position herausbewegt, arretiert ihn gleichzeitig der Arretierungshaken 22 in dieser Stellung.When it reaches its actual place of use pushes the mask wearer the regulator 1 with its connecting piece 6 all the way into the locking groove 8 into the coupling element 5, on the one hand the ambient air intake openings 11 are closed and at the same time the release switch 18 is actuated with which released the bottle air supply valve 13 for breathing becomes. So that the regulator is not inadvertently moved out of this position, arrested him at the same time the locking hook 22 in this position.

Nach Ende des Einsatzes entriegelt der Maskenträger den Arretierungshaken 22 und zieht den Lungenautomaten 1 wieder zurück in die erste Position. Dabei werden die Umgebungsluftansaugöffnungen 11 wieder geöffnet und gleichzeitig das Flaschenluftzuführventil in seiner Betätigung gesperrt, da der Freigabeschalter 18 in seine ursprüngliche Position zurückgleitet.After use, the mask carrier unlocks the Locking hook 22 and pulls the regulator 1 back to the first position. The Ambient air intake openings 11 opened again and at the same time the cylinder air supply valve in its operation locked because the release switch 18 in its slides back to original position.

Außer dieser hier beschriebenen Variante ist es auch möglich, anstelle der Verschiebebewegung mit dem Anschlußstutzen einen um diesen verschwenkbaren Ring mit Verschlüssen für Umgebungsluftansaugöffnungen und Betätigungselement für den Freigabeschalter vorzusehen. Außerdem kann ein solcher Lungenautomat außer an einer Atemschutzmaske auch an einem entsprechenden Anschluß einer Haube eines Anzuges etc. angebracht sein. Im übrigen ist es möglich, diese Erfindung sowohl bei Normaldruckautomaten als auch bei Überdruckautomaten einzusetzen.In addition to the variant described here, it is also possible instead of moving with the connecting piece one around this swiveling ring Closures for ambient air intake openings and actuating element to be provided for the release switch. In addition, such a regulator can be used on one Respirator mask also on a corresponding connection be attached to a hood of a suit etc. in the remaining, it is possible to both this invention Normal printing machines as well as overpressure machines to use.
