Description

Die Erfindung betrifft ein Anschlußstück für mit Gewindeanschluß versehene Atemschutzmasken und/oder für mit Führungszylinder und federnden Rastnasen ausgebildete Steckanschlüsse von Lungenautomaten.The invention relates to a fitting for threaded connection provided respirators and / or for with Guided cylinder and resilient locking lugs trained Plug connections of lung regulators.

Die bekannten Atemschutzmasken sind überwiegend mit einem genormten einheitlichen Gewindeanschluß zur wahlweisen Verbindung mit dem Lungenautomaten eines Preßluftatmers bzw. Schlauchgerätes oder einem Filter ausgerüstet. Bekannt sind des weiteren Atemschutzmasken, die über einen Steckanschluß zur Verbindung eines entsprechend ausgebildeten Lungenautomaten mit der Maske verfügen.The well-known respirators are predominantly with a standardized uniform threaded connection for optional Connection to the regulator of a compressed air breathing apparatus or a hose unit or a filter. Known are also respirators that have a Plug connection for connecting a trained accordingly Regulator with the mask feature.

Die wegen der einheitlichen Ausführung der Gewindeanschlüsse seit langem bewährten und weit verbreiteten Atemschutzmasken sind vielseitig einsetzbar. Sie sind jedoch insofern nachteilig, als das Anschließen bzw. Wechseln des Preßluftatmers beim Einschrauben des Lungenautomaten mit einem erheblichen Zeitaufwand verbunden ist. Die beiden miteinander zu verbindenden Gewindeteile können insbesondere unter den schwierigen Bedingungen während eines Feuerwehr- oder anderen Rettungseinsatzes zueinander verkantet angesetzt werden, so daß sich die Zeit für das Anschließen weiter erhöht oder sogar eine Beschädigung der Gewindeteile zu befürchten ist. The because of the uniform design of the threaded connections long-established and widespread Respirators are versatile. They are, however disadvantageous, as the connecting or changing the compressed air respirator when screwing in the regulator associated with a considerable amount of time. The two threaded parts to be joined together especially in the difficult conditions during a fire brigade or other rescue mission to each other tilted be set so that the time for connecting further increased or even damage the threaded parts is to be feared.

Nachteilig ist weiterhin die feste Verschraubung und der starre, nicht drehbare Sitz des an der Atemschutzmaske angeschlossenen und über eine Schlauchleitung mit einem Preßluftreservoir verbundenen Lungenautomaten. Dadurch ist einerseits die freie Beweglichkeit des Kopfes des Maskenträgers eingeschränkt und andererseits kann sich die Verschraubung des Lungenautomaten in dem Gewindeanschlußstück der Maske aufgrund eines von der an den Lungenautomaten angeschlossenen Schlauchleitung ausgeübten Drehmoments lösen.Another disadvantage is the fixed screw and the rigid, non-rotatable seat on the respirator connected and via a hose line with a Compressed air reservoir connected to respiratory machine. Thereby on the one hand is the free mobility of the head of the Maskenträgers restricted and on the other hand can itself the screw connection of the regulator in the threaded connection piece the mask due to one of the s.den Regulators exercised hose line exercised Loosen torque.

Die bekannten Lungenautomaten mit Steckanschlußstück gewährleisten eine schnelle und einfache Verbindung mit einer entsprechend ausgebildeten Atemschutzmaske sowie die Drehbeweglichkeit des Lungenautomaten an der Maske. Ihre Anwendung ist jedoch auf Masken mit Steckanschlußstück beschränkt. Da das Steckanschlußsystem nicht mit dem Gewindeanschlußsystem kompatibel ist, kann es bei Katastropheneinsätzen immer wieder zu Problemen bei der gegenseitigen Hilfeleistung zwischen den Benutzern unterschiedlicher Systeme kommen.Ensure the known regulator with plug-in connector a quick and easy connection with one appropriately trained respirator and the Rotational mobility of the regulator on the mask. Your Application is however on masks with plug-in connector limited. Since the plug connection system does not work with the threaded connection system it can be compatible with disaster operations always problems with the mutual Assistance between users of different Systems are coming.

Der Erfindung liegt daher die Aufgabe zugrunde, den Anschluß für Atemschutzmasken mit Einheitsgewindeanschluß sowie für Lungenautomaten mit Steckanschluß so auszubilden, daß eine schnelle und drehbewegliche Herstellung der Verbindung gewährleistet ist.The invention is therefore based on the object, the Connection for respirators with standard thread connection as well as for lung units with plug connection in such a way, that a fast and rotatable production of Connection is guaranteed.

Erfindungsgemäß wird die Aufgabe mit einem gemäß den Merkmalen des Patentanspruchs 1 ausgebildeten Anschlußstück für Atemschutzmasken bzw. Lungenautomaten gelöst. Weitere Merkmale und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen. According to the invention, the object with a according to the Characteristics of claim 1 trained Connecting piece for respirators resp solved. Further features and advantageous developments The invention will become apparent from the dependent claims.

Der grundlegende Erfindungsgedanke besteht mit anderen Worten in der Zuordnung eines mit dem Gewindeanschluß der Maske verschraubbaren, als rotationssymmetrischer Hohlkörper ausgebildeten Handrades mit Gewindehülse, das am Innenumfang gleichzeitig als Steckanschlußhülse für einen zur drehbeweglichen Steckverbindung mit der Maske vorgesehenen Lungenautomaten von Preßluftatmern ausgebildet ist. Das erfindungsgemäße Handrad kann jeweils separat mit der Maske verschraubt oder drehbeweglich am Lungenautomaten gehalten sein, wobei in beiden Fällen einfach und schnell eine sichere Verbindung zwischen Maske und Lungenautomat hergestellt werden kann.The basic idea of the invention exists with others Words in the assignment of one with the threaded connection of the Mask screwed, as a rotationally symmetrical hollow body trained handwheel with threaded sleeve, the Inner circumference at the same time as a plug-in connection sleeve for a intended for rotatable connector with the mask Regulatory lungs designed by Preßluftatmern is. The handwheel according to the invention can each separately screwed with the mask or rotatable at the regulator be held in both cases simple and quickly a secure connection between mask and regulator can be produced.

An die Maske können somit wahlweise mit einem Steck- oder einem Gewindeanschluß versehene Lungenautomaten angeschlossen werden. Es können nunmehr die Vorteile des Steckanschlusses, nämlich schnelle und einfache Herstellung der Verbindung und freie Drehbeweglichkeit des über eine Schlauchverbindung an ein Druckluftreservoir angeschlossenen Lungenautomaten, bei den weit verbreiteten Atemschutzmasken mit genormtem, einheitlichen Gewindeanschluß genutzt werden. Bei Brand- und Rettungseinsätzen ist eine gegenseitige Hilfeleistung auch zwischen den Nutzern beider unterschiedlicher Systeme möglich.To the mask can thus optionally with a plug or connected to a threaded connection lung regulators become. It can now take advantage of Plug connection, namely fast and easy production the connection and free rotation of the over a hose connection connected to a compressed air reservoir Lunging machines, in the widespread Respirators with standard, uniform threaded connection be used. For fire and rescue operations is a mutual help also between the Users of both different systems possible.

Das Handrad mit Gewinde- und Steckanschlußhülse weist ein Normaußengewinde auf und ist am Innenumfang als Steckanschlußhülse mit einer umlaufenden Rastnut sowie einem Haltezylinder zur radialen Fixierung und axialen drehbeweglichen Halterung des Lungenautomaten ausgebildet. The handwheel with threaded and plug connection sleeve has a Normaußengewinde on and is on the inner circumference as a plug-in socket with a circumferential locking groove and a Holding cylinder for radial fixation and axial rotatable Holder of the lung machine is formed.

Der Haltezylinder, in dem der Lungenautomat auch abdichtend geführt ist, ist zur Ringnut hin zu einem trichterförmigen Führungsteil für das schnelle Auffinden der Verbindungsstelle erweitert.The holding cylinder, in which the regulator is also sealing is guided, is the annular groove towards a funnel-shaped Guide part for quickly locating the joint extended.

An das trichterförmige Führungsteil schließt sich das am Außenumfang profiliertes Handrad an, das eine schnelle manuelle Schraubverbindung mit der Maske ermöglicht.At the funnel-shaped guide part closes the am Outer circumference profiled handwheel on, which is a fast manual screw connection with the mask allows.

In das Handrad ist am Innenumfang die umlaufende Rastnut zur Aufnahme der Rastnasen vom federnd gelagerten Verriegelungselementen des anzuschließenden Lungenautomaten integriert.In the handwheel is on the inner circumference of the circumferential locking groove for receiving the detents from the spring-mounted locking elements integrated to the connected regulator.

Das Steckanschlußstück des anzuschließenden Lungenautomaten ist auf Gleitflächen des Handrades bzw. der Rastnut drehbeweglich gelagert.The plug-in fitting of the regulator to be connected is on sliding surfaces of the handwheel or the detent groove rotatably mounted.

Am Lungenautomat vorgesehene Verriegelungselemente sind nach dem Einrasten der Rastnasen in der Rastnut feststellbar, so daß der mit dem Steckanschluß versehene Lungenautomat mit einem drehbeweglichen Handrad versehen ist und durch Verschrauben mit der Maske verbunden werden kann.At the regulator are provided locking elements lockable in the locking groove after engagement of the detents so that the regulator provided with the plug connection is provided with a rotatable handwheel and be connected by screwing with the mask can.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert. Es zeigen:

Das entsprechend zylindrisch ausgebildete Gewindeanschlußstück 1, das in bekannter Weise mit einem Maskenkörper (nicht dargestellt) verbunden ist, weist an der Innenfläche ein bei Atemschutzmasken übliches Normgewinde 2, z.B. M 45x3, und eine Dichtung 3 auf. Mit dem Gewindeanschlußstück 1 ist eine Steckanschlußhülse 4 mit Handrad 16 verschraubt, um als Kupplungselement für einen Lungenautomaten 5 mit Steckanschlußteil zu dienen. Das Steckanschlußteil des Lungenautomaten 5 umfaßt zwei radial bewegliche, gegenüberliegend angeordnete Verriegelungselemente 6 mit Rastnasen 7, die entgegen der Wirkung einer Druckfeder 8 manuell nach innen verschoben werden können und durch die Federkraft nach außen gedrückt werden. Außerdem weist das Steckanschlußteil einen Führungszylinder 9 mit an dessen Umfangsfläche vorgesehener Nut zur Aufnahme eines Dichtungselements 10 auf.The correspondingly cylindrical threaded connection piece 1, in a known manner with a mask body (not shown) is connected to the Inner surface of a normal with standard respiratory masks 2, e.g. M 45x3, and a seal 3 on. With the threaded connection 1 is a plug-in connection sleeve 4 with handwheel 16 bolted to a coupling element for a Latching machine 5 with plug connection part to serve. The Plug connection part of the regulator 5 includes two radially movable, oppositely arranged locking elements 6 with locking lugs 7, which counteract the effect a compression spring 8 are moved manually inward can be pressed and by the spring force to the outside. In addition, the plug connection part has a guide cylinder 9 with provided on its peripheral surface groove for receiving a sealing element 10.

Die Steckanschlußhülse 4 umfaßt gleichzeitig eine Gewindehülse 11 mit einem Normaußengewinde 12 entsprechend dem Normgewinde 2 des Gewindeanschlußstücks 1 der Maske. Die Gewindehülse 11 geht in ein trichterartiges Führungsteil 13 über, an das sich eine Gleitfläche 14 und eine umlaufende Rastnut 15 anschließen. Den oberen Rand der Steckanschlußhülse 4 bildet ein Handrad 16 mit einer oberen Gleitfläche 17, einer Labyrinthnut 18 und einer zahnartig abgestuften Außenumfangsfläche 19. Die Innenumfangsfläche des Handrades 16 ist eine abgeschrägte Gleitfläche 20.The plug-in connection sleeve 4 at the same time comprises a threaded sleeve 11 with a Normaußengewinde 12 according to the Standard thread 2 of the threaded connection piece 1 of the mask. The Threaded sleeve 11 goes into a funnel-like guide part 13 on, to which a sliding surface 14 and a circumferential Connect locking groove 15. The upper edge of the plug-in connection sleeve 4 forms a handwheel 16 with an upper one Sliding surface 17, a labyrinth groove 18 and a tooth-like stepped outer peripheral surface 19. The inner peripheral surface the handwheel 16 is a tapered sliding surface 20.

Wenn eine in üblicher Weise mit einem Gewindeanschlußstück 1 versehene Atemschutzmaske mit einem Lungenautomat 5 mit Steckanschlußteil verbunden werden soll, wird zuvor lediglich das Handrad 16 mit Steckanschlußhülse 4 mit seiner Gewindehülse 11 in dem Gewindeanschlußstück 1 verschraubt. Die Gewindehülse 11 und das Gewindeanschlußstück 1 sind über die Dichtung 3 gegeneinander abgedichtet und lagestabil gesichert. Da die Steckanschlußhülse 4 ein Handrad 16 mit einer gezahnten Außenumfangsfläche 19 aufweist, kann sie schnell und fest mit dem Gewindeanschlußstück 1 verbunden und auch auf einfache Weise wieder manuell gelöst werden. Die Atemschutzmaske bzw. der Lungenautomat kann somit schnell von "Gewindeanschlußbetrieb" auf "Steckanschlußbetrieb" (oder umgekehrt) umgestellt werden.If one in the usual way with a threaded connection 1 provided respirator with a regulator 5 is to be connected to plug-in connector, is previously only the handwheel 16 with plug-in connection sleeve 4 with screwed his threaded sleeve 11 in the threaded connection piece 1. The threaded sleeve 11 and the threaded connection piece 1 are about the seal 3 against each other sealed and stored stable. Since the plug connection sleeve 4 a hand wheel 16 with a toothed outer peripheral surface 19, it can be fast and firm connected to the threaded connection piece 1 and also on easy way to be solved manually again. The respirator or the regulator can thus quickly from "Thread connection operation" to "Plug connection operation" (or conversely).

Das Herstellen der Steckverbindung ist unkompliziert und erfolgt in kürzester Zeit, da der Führungszylinder 9 des Lungenautomaten 5 über die weite Öffnung und das trichterartige Führungsteil 13 gleichsam von selbst in den zylindrisch führenden Haltezylinder 11' der Steckanschlußhülse 4 gleitet. Dabei werden die Rastnasen 7 mit ihrer Abschrägung 7a entlang der abgeschrägten Gleitfläche 20 des Handrades 16 durch leichten manuellen Druck auf den Lungenautomaten 5 entgegen der Wirkung der Druckfeder 8 radial nach innen verschoben, um anschließend in der Rastnut 15 der Steckanschlußhülse 4 federnd zu verrasten. Der Lungenautomat 5 sitzt nun axial unbeweglich, aber auf der Gleitflächen 14 und 17 drehbeweglich, sowie über das Dichtelement 10 abgedichtet und im Haltezylinder 11 radial fixiert in der Steckanschlußhülse 4. Das Trennen des Lungenautomaten 5 von der Steckanschlußhülse 4 erfolgt, indem die Verriegelungselemente 6 manuell nach innen gedrückt werden, so daß der Lungenautomat 5 entriegelt ist und abgenommen werden kann. In Fig. 1 ist das Verriegelungselement 6 zum besseren Verständnis in der linken Bildhälfte in verriegeltem Zustand und in der rechten Bildhälfte in eingeschobenem, unverriegeltem Zustand dargestellt. Das Trennen kann aber auch durch Drehen des Handrades 16 und damit das Abschrauben der Steckanschlußhülse 4 (Gewindehülse 11) erfolgen, so daß ein Bauteil mit Gewindeanschluß, beispielsweise ein Filter oder ein Lungenautomat mit Gewindeanschluß, in die Maske geschraubt werden kann.The production of the connector is straightforward and takes place in a very short time, since the guide cylinder 9 of Regulator 5 over the wide opening and the funnel-like Guide member 13 as it were by itself in the cylindrical leading holding cylinder 11 'of the plug-in connection sleeve 4 slides. The locking lugs 7 with their Bevel 7a along the tapered sliding surface 20th of the hand wheel 16 by slight manual pressure on the Regulator 5 against the action of the compression spring. 8 moved radially inward to subsequently in the Locking groove 15 of the plug-in connection sleeve 4 to lock resiliently. The regulator 5 is now sitting axially immobile, but on the sliding surfaces 14 and 17 rotatably, as well as over the Sealed sealing element 10 and radially in the holding cylinder 11 fixed in the plug connection sleeve 4. Separating the Regulator 5 is made of the plug-in connection sleeve 4, by manually pushing the locking elements 6 inwards be so that the regulator 5 is unlocked and can be taken off. In Fig. 1, the locking element 6 for better understanding in the left Half of the picture in the locked state and in the right one Half of the picture shown in the pushed in, unlocked state. The separation can also be done by turning the Handwheel 16 and thus unscrewing the plug-in connection sleeve 4 (threaded sleeve 11) take place, so that a component with threaded connection, such as a filter or a Regulator with threaded connection, screwed into the mask can be.

Mit dem oben beschriebenen Anschlußsystem über ein als Steckanschlußhülse 4 und Gewindehülse 11 ausgebildetes Anschlußstück mit Handrad 16 kann somit wahlweise eine Schraub- oder auch eine Steckverbindung mit der Atemschutzmaske oder dem Lungenautomaten sicher und schnell hergestellt werden, wobei an die Maske je nach Ausführungsart sowohl Überdrucksysteme als auch Normaldrucksysteme angeschlossen werden können. Das heißt, alle marktüblichen Atemschutzmasken mit Normgewindeanschluß können wahlweise am Schraubanschluß oder am Steckanschluß getrennt werden. Unter Zwischenschaltung der Steckanschlußhülse 4 als Steckverbindung angeschlossene Lungenautomaten 5 sind drehbeweglich an der mit einem Gewindeanschlußstück 1 ausgerüsteten Atemschutzmaske gehalten, so daß die Beweglichkeit des Kopfes des Benutzers diesbezüglich nicht beeinträchtigt wird.With the connection system described above via a Plug connection sleeve 4 and threaded sleeve 11 trained Connector with handwheel 16 can thus either a Screw or a plug connection with the respirator or the lung machine safely and quickly be made, taking to the mask depending on the embodiment both overpressure systems and normal pressure systems can be connected. That is, all commercially available Respirators with standard thread connection can optionally separated at the screw connection or at the plug connection become. With the interposition of the plug connection sleeve 4 connected as plug connection lung regulators 5 are rotatable on the with a threaded connection 1 equipped respirator, so that the agility of the user's head in this regard is not affected.

Die Erfindung ist nicht auf das vorstehend erläuterte Ausführungsbeispiel beschränkt. Vielmehr sind im Rahmen des Grundgedankens der Erfindung, der in der einstückigen Kombination eines Handrades mit einer Gewindehülse und einer Steckanschlußhülse besteht, zahlreiche Modifikationen denkbar. The invention is not based on the above Embodiment limited. Rather, they are in the frame the basic idea of the invention, which in the one-piece Combination of a handwheel with a threaded sleeve and a plug-in socket consists of numerous modifications conceivable.
