Abstract

The invention relates to a device for connecting breathing apparatus to a breathing opening in which there is a closable ambient air intake aperture and a release switch for a bottled air supply valve to the breathing apparatus. With such devices it is a drawback if the breathing apparatus is inserted into the mask only at the point of use and thus wastes valuable time. To prevent this, a connector of the invention is designed in such a way that it comprises an adjuster (6) which, with the breathing apparatus (1) connected to the mask, can be manually set between a first position in which the ambient air intake aperture (11) is closed and at the same time the bottled air supply valve (13) is released and a second position in which the ambient air intake aperture is opened and at the same time the bottled air supply valve is locked, especially in its closed position.

Description

Atemanschluß mit LungenautomatBreathing connection with regulator
B e s c h r e i b u n gDescription
Die Erfindung betrifft eine Vorrichtung zur Ankopplung eines Lungenautomaten an einen Atemanschluß mit zumin¬ dest einer verschließbaren Umgebungsluftansaugöffnung und einem Freigabeschalter für ein Flaschenluftzuführ¬ ventil am Lungenautomaten.The invention relates to a device for coupling a regulator to a breathing connection with at least one closable ambient air intake opening and a release switch for a cylinder air supply valve on 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 Atemluft¬ flasche, einem Gebläse etc. verbunden. Derartiges, so¬ genanntes schweres Atemschutzgerät, wird beispielsweise von Feuerwehrleuten in Brandsituationen eingesetzt, wo die Umgebungsluft giftige Gase, Rauch etc. enthält.Protective suits or respiratory masks such as full face masks, half masks or respiratory protection hoods are considered as breathing connections. They are connected to an air supply, for example a breathing air bottle, a blower, etc., via an automatic lung regulator. Such a so-called heavy breathing apparatus is used, for example, 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 anzukop¬ peln. Bis dahin wird an der Ansaugöffnung der Atem¬ schutzmaske Luft aus der Umgebung eingeatmet. Beim An¬ koppeln des Lungenautomaten wird dann in diese Ansaug¬ öffnung ein an dem Lungenautomaten befindlicher An¬ schlußstutzen eingesetzt, wobei gleichzeitig im Lungen¬ automaten ein Flaschenluftzuführventil freigegeben wird, so daß über dieses Ventil im Lungenautomaten be¬ darfsgerecht Flaschenluft in die Atemschutzmaske flie¬ ßen kann.It has hitherto been known to put on a breathing air bottle and a breathing mask, but to couple the regulator to connect the mask to the bottle only at the actual place of use to the breathing mask. Until then, air from the surroundings is inhaled at the suction opening of the breathing mask. When the regulator is connected, a connection piece located on the regulator is inserted into this intake opening, a cylinder air supply valve being released in the regulator at the same time, so that bottle air flows into the breathing mask as needed via this valve in the regulator can eat.
ERSATZBLÄΓT(REGEL26) Ein wesentlicher Nachteil dieser bekannten Vorrichtung liegt darin, daß es im entscheidenden Augenblick Zeit benötigt und damit zu lange dauern kann, bis der An¬ schlußstutzen des Lungenautomaten in die Ansaugöffnung der Atemschutzmaske eingesetzt und damit das Atmen von Umgebungsluft auf Flaschenluft umgestellt ist.SPARE BLADE (RULE 26) A major disadvantage of this known device is that it takes time at the decisive moment and can therefore take too long until the connection piece of the regulator is inserted into the suction opening of the respiratory mask and the breathing is switched from ambient air to bottle air.
Aufgabe der vorliegenden Erfindung ist es daher, eine bekannte Vorrichtung so weiterzubilden, daß dieses Um¬ stellen in kürzester Zeit und ohne umständliches Han¬ tieren durchgeführt werden kann.The object of the present invention is therefore to develop a known device in such a way that this changeover can be carried out in the shortest possible time and without cumbersome handling.
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 ver¬ stellbar ist zwischen einer ersten Position, in der die Umgebungsluftansaugöffnung verschlossen und gleichzei¬ tig das Flaschenluftzuführventil freigegeben ist, und einer zweiten Position, in der die Umgebungsluftansaug¬ öffnung geöffnet und gleichzeitig das Flaschenluftzu¬ führventil insbesondere in seiner Geschlossenstellung gesperrt ist." This object is achieved according to the invention in that the coupling device for the breathing apparatus to the breathing connection has an actuator which, when the breathing apparatus is attached to the breathing connection, can be adjusted manually between a first position in which the ambient air intake opening 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 is opened and at the same time the bottle air supply valve is blocked, in particular in its closed position. "
Diese Erfindung hat den Vorteil, daß ein Maskenträger den Lungenautomaten bereits beim Anlegen des Atem¬ schutzgerätes 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 Um¬ gebungsluft atmen um so seinen Flaschenluftvorrat zu schonen, und erst am Einsatzort mit einer kurzen manu- eilen Betätigung eines Stellgliedes seine Atemluft von Umgebungsluft auf Flaschenluft umstellen. Dies ist er¬ heblich 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 wearer can couple the lung automat to his respirator already when the respirator is put on, without bottle air already flowing into the respirator. As before, the mask wearer can approach the actual place of use and still breathe ambient air in order to protect his bottle air supply, and only at the place of use with a short manual If you actuate an actuator, switch your breathing air from ambient air to bottle air. This is considerably faster and easier than the cumbersome, time-consuming insertion of the regulator with its connecting piece into the suction opening, as has been done up to now.
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 ge¬ öffnet ist und gleichzeitig das Flaschenluftzuführven¬ til in seiner Geschlossenstellung gesperrt ist.Switching back to ambient air can also be carried out quickly and easily, since for this purpose only the actuator has to be returned to the other position in which the ambient air intake opening is opened 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 be¬ vorzugten Ausführungsform ist das Stellglied aber direkt durch den Anschlußstutzen für den Lungenautoma¬ ten gebildet und insbesondere über eine Verschiebung des Lungenautomaten betätigbar. Das heißt, daß mit einem einfachen Druck von vorne auf den Lungenautomaten das Stellglied betätigt wird und die Luftzufuhr um¬ schaltet, während bei einem anschließenden Zug am Lungenautomaten zurückgeschaltet wird. Damit die Um¬ schaltung von dem einen in den anderen Zustand nicht ungewollt passiert, ist es vorteilhaft, wenn das Stell¬ glied in den zwei Endpositionen einrastbar ist, so daß bei seiner Betätigung ein kleiner Anfangswiderstand zu überbrücken ist.The adjustment of the actuator can take place either via a rotary or a swivel movement, but in a preferred embodiment the actuator is formed directly by the connecting piece for the lung automat and can be actuated in particular by displacing the regulator. This means that the actuator is actuated and the air supply is switched over with a simple push from the front onto the lung automats, while switching back at the lung automats during a subsequent train. So that the changeover from one state to the other does not occur unintentionally, it is advantageous if the actuator can be locked in the two end positions, so that a small initial resistance has to be bridged when it is actuated.
Insbesondere in der Position, in der durch das Stell¬ glied die Umgebungsluftansaugöffnung verschlossen und gleichzeitig das Flaschenluftzuführventil freigegeben wird, kann bei einer bevorzugten Ausführungsform das Stellglied selbsttätig arretieren. Damit ist gewährlei¬ stet, 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.In particular in the position in which the ambient air intake opening is closed and at the same time the bottle air supply valve is released, the actuator can lock itself in a preferred embodiment. This ensures that in a situation in which the inhalation of ambient air would be harmful due to the gases contained in it, an accidental switching back of the actuator is prevented.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausfüh¬ rungsbeispieles gemäß den beigefügten Zeichnungen. Dabei zeigtFurther advantages and features of the invention result from the following description of an exemplary embodiment according to the attached drawings. It shows
Figur 1 eine erfindungsgemäße Ankoppelvorrichtung mit geöffneter Umgebungsluftansaugöffnung und ge¬ sperrtem Flaschenluftzuführventil;1 shows a coupling device according to the invention with an open ambient air intake opening and a blocked bottle air supply valve;
Figur 2 eine erfindungsgemäße AnkoppelVorrichtung mit geschlossener Umgebungsluftansaugöffnung und freigegebenem Flaschenluftzuführventil.Figure 2 shows 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 Atemschutz¬ maske ist in einen Maskenkörper 3 ein Sichtfenster 4 eingesetzt. Außerdem ist mit dem Maskenkörper 3 ein An¬ koppelelement 5 dicht verbunden. Hierzu wird das Ankop¬ pelelement 5, das mit einem Außengewinde versehen ist, in ein am Maskenkörper 2 befindliches korrespondieren¬ des Gewinde eingeschraubt. Im Ankoppelelement 5 ist ein Anschlußstutzen 6 des Lungenautomaten 1 verschiebbar.Figure 1 shows a regulator 1, which is coupled to a respirator 2. In the respiratory protection mask, a viewing window 4 is inserted into a mask body 3. In addition, a coupling element 5 is tightly connected to the mask body 3. For this purpose, the coupling element 5, which is provided with an external thread, is screwed into a corresponding thread located on the mask body 2. In the coupling element 5, a connecting piece 6 of the regulator 1 can be moved.
Dabei kann der Anschlußstutzen 6 mit einem vorge¬ spannten Element 7 in Rastnuten 8, 9, die im Ankoppel¬ element 5 ausgebildet sind, einrasten. Zwischen dem An¬ koppelelement 5 und dem Anschlußstutzen 6 ist außerdem eine Ringdichtung 10 vorgesehen, die verhindert, daß Nebenluft durch den zwischen Ankoppelelement 5 und An¬ schlußstutzen 6 gebildeten Spalt hindurchgezogen wird.In this case, the connecting piece 6 with a prestressed element 7 can snap into locking grooves 8, 9 which are formed in the coupling element 5. There is also between the coupling element 5 and the connecting piece 6 an annular seal 10 is provided which prevents secondary air from being drawn through the gap formed between coupling element 5 and connecting piece 6.
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 entspre¬ chend den Pfeilen 12 Umgebungsluft in das Maskeninnere strömen kann. An seinem dem Ankoppelelement 5 abgewand¬ ten Ende trägt der Anschlußstutzen 6 den Lungenautoma¬ ten 1, mit dem ein Flaschenluftzuführventil 13 betätig¬ bar ist. In der Figur 1 ist dieses Ventil in der ge¬ schlossenen Stellung dargestellt. Es verschließt die Leitung 14, die zu einer Atemluftflasche führt.In its area lying outside the coupling element 5, the connecting piece 6 has a plurality of ambient air suction openings 11 distributed over its circumference, through which ambient air can flow into the interior of the mask in accordance with the arrows 12 when the mask wearer inhales. At its end facing away from the coupling element 5, the connecting piece 6 carries the lung automat 1, with which a bottle air supply valve 13 can be actuated. This valve is shown in the closed position in FIG. It closes 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 connected to a movable breathing membrane 16 via a linkage 15. The linkage 15 is articulated on a rocker arm 17 which is connected to a release switch 18 which is guided outwards from the housing of the regulator.
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.If it is not actuated, as shown in FIG. 1, this release switch 18 brings the rocker arm 17 into a position which blocks the bottle air supply valve in its closed position.
In der Figur 2 ist der Anschlußstutzen 6 in das Ankop¬ pelelement 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 gleich¬ zeitig mit einem an dem Ankoppelelement 5 ausgebildeten Bund 20 der Freigabeschalter 18 betätigt. Dadurch kippt der Kipphebel 17 in eine Position, in der das Flaschen¬ luftzuführventil 13 über das Gestänge 15 durch die Atemmembran 16 betätigt werden kann: Wenn der Masken¬ träger 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 Maskenträ¬ ger strömen kann. Atmet der Maskenträger aus, so wird der Unterdruck abgebaut und die Atemmembran 16 bewegt sich wieder in ihre Ursprungsposition zurück, wobei das Ventil 13 geschlossen und so nicht unnötig Flaschenluft verbraucht wird.In FIG. 2, the connecting piece 6 has been moved into the coupling element 5 of the mask body 3 until it engages with the prestressed element 7 in the locking groove 8 located further inside. The end of the coupling element 5 facing the regulator 1 seals in cooperation with a second ring seal 19 from the ambient air intake openings 11. The release switch 18 is actuated simultaneously with a collar 20 formed on the coupling element 5. As a result, the rocker arm 17 tilts into a position in which the bottle air supply valve 13 can be actuated via the linkage 15 through the breathing membrane 16: When the mask wearer breathes in, the space that is to the left of the breathing membrane 16 in FIG. 2 is produced is shown, a negative pressure, which the membrane 16 follows. The bottle air supply valve 13 is moved downward via the linkage 15 and thus opens the line 14, so that bottle air can flow to the mask carrier in accordance with the arrows 21. If the mask wearer exhales, the negative pressure is released and the breathing membrane 16 moves back into its original position, the valve 13 being closed and bottle air not being consumed unnecessarily.
Beim Einschieben des Anschlußstutzens 6 in das Ankop¬ pelelement 5 greift ein Arretierungshaken 22 hinter den Bund 20 des Ankoppelelementes.When the connecting piece 6 is pushed into the coupling element 5, a locking hook 22 engages behind the collar 20 of the coupling element.
Zusammenfassend funktioniert die dargestellte Vorrich¬ tung wie folgt: Nachdem der Maskenträger die Atem¬ schutzmaske 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 Ge¬ winde in den Maskenkörper 2 eingeschraubt ist. Der An¬ schlußstutzen rastet in der ersten Rastnut 9 ein. In dieser Position kann Umgebungsluft durch die Umgebungs¬ luftansaugöffnungen 11 in die Atemmaske strömen, wenn der Maskenträger einatmet. Bei Erreichen seines eigentlichen Einsatzortes schiebt der Maskenträger den Lungenautomaten 1 mit seinem An¬ schlußstutzen 6 ganz bis zum Einrasten in die Rastnut 8 in das Ankoppelelement 5, wobei einerseits die Umge¬ bungsluftansaugöffnungen 11 verschlossen werden und gleichzeitig der Freigabeschalter 18 betätigt wird, mit dem das Flaschenluftzuführventil 13 zum Atmen freigege¬ ben wird. Damit der Lungenautomat sich nicht ungewollt wieder aus dieser Position herausbewegt, arretiert ihn gleichzeitig der Arretierungshaken 22 in dieser Stel¬ lung.In summary, the device shown works as follows: after the mask wearer has put on the breathing mask 2, he introduces the regulator 1 connected via line 14 to a breathing air bottle with its connecting piece 6 into the coupling element 5 of the breathing mask, which is connected with a Ge ¬ winch is screwed into the mask body 2. The connecting piece engages in the first locking groove 9. In this position, ambient air can flow through the ambient air intake openings 11 into the breathing mask when the mask wearer inhales. When it reaches its actual place of use, the mask wearer pushes the regulator 1 with its connecting piece 6 all the way into the locking groove 8 into the coupling element 5, the ambient air intake openings 11 being closed on the one hand and the release switch 18, with which the Bottle air supply valve 13 is released for breathing. So that the regulator does not move out of this position unintentionally, the locking hook 22 simultaneously locks it 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 Be¬ tätigung 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 into the first position. The ambient air intake openings 11 are opened again and at the same time the actuation of the bottle air supply valve is blocked, since the release switch 18 slides back into its original position.
Außer dieser hier beschriebenen Variante ist es auch möglich, anstelle der Verschiebebewegung mit dem An¬ schlußstutzen einen um diesen verschwenkbaren Ring mit Verschlüssen für Umgebungsluftansaugöffnungen und Be¬ tätigungselement 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 this variant described here, it is also possible to provide a ring which can be pivoted about this with closures for ambient air intake openings and actuating element for the release switch instead of the displacement movement with the connecting piece. In addition, such a regulator can be attached to a corresponding connection of a hood of a suit, etc., in addition to a breathing mask. Otherwise, it is possible to use this invention both in normal printing presses and in overpressure presses.
