Description

Die Erfindung betrifft ein Anschlußstück für mit Gewindeanschluß ausgerüstete Atemschutzmasken gemäß dem Oberbegriff des Patentanspruches 1. Ein derartiges Anschlußstück ist aus der EP 0 090 083 A2 bekannt. 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 invention relates to a fitting for equipped with threaded connection respirators according to the preamble of claim 1. Such a fitting is from the EP 0 090 083 A2 known. The known respirators are predominantly equipped with a standardized uniform threaded connection for selective connection to the regulator of a compressed air respirator or breathing apparatus or a filter. Furthermore, respiratory protective masks are known which have a plug-in connection for connecting a correspondingly designed lung machine to the mask.

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 long-proven and widespread because of the uniform design of the threaded connections respirators are versatile. However, they are disadvantageous in that the connection or exchange of the compressed air breathing when screwing the regulator is associated with a considerable amount of time. The two threaded parts to be joined together can be tilted towards each other especially under difficult conditions during a fire or other rescue operation, so that the time for connecting further increased or even damage to 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 connected to the respirator and connected via a hose with a compressed air reservoir regulator. As a result, on the one hand the free mobility of the head of the mask wearer is limited and on the other hand may be loosen the screw connection of the regulator in the threaded connection of the mask due to a torque exerted by the hose connected to the regulator.

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.The known regulator with plug-in connector ensure a quick and easy connection with a suitably trained respirator and the rotational mobility of the regulator on the mask. However, their application is limited to masks with plug-in connector. Since the plug-in connection system is not compatible with the threaded connection system, it can often lead to problems in mutual assistance between the users of different systems during disaster operations.

Bei dem in der EP 0 090 083 A2 beschriebenen Geräte-Schnellanschluß eines Lungenautomaten mit Steckanschluß an eine Atemschutzmaske mit Schraubanschluß ist der Steckanschluß an dem Schraubanschluß mit einem federnden Sicherungsring verriegelt und mit seinem Steckstutzen nebst Dichtung in einem Innenzylinder des Schraubanschlusses abdichtend gehalten. Mit diesem Anschlußstück sind weder ein schnelles Anschließen des Lungenautomaten möglich, noch dessen gute Drehbeweglichkeit gewährleistet.In the in the EP 0 090 083 A2 described device quick connection of a regulator with plug connection to a respirator with screw the plug connection is locked to the screw with a resilient retaining ring and sealingly held with its plug-in piece together with seal in an inner cylinder of the screw. With this connector neither a quick connection of the regulator are possible, nor ensures its good rotational mobility.

Der Erfindung liegt daher die Aufgabe zugrunde, das Anschlußstück für Atemschutzmasken mit Gewindeanschluß sowie für Lungenautomaten mit Steckanschluß so auszubilden, daß eine schnelle Herstellung und gute Drehbeweglichkeit der Verbindung gewährleistet sind.The invention is therefore the object of the fitting for respirators with threaded connection and for pulmonary with plug connection form so that a fast production and good rotational mobility of the connection are guaranteed.

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

Der grundlegende Erfindungsgedanke besteht in der Zuordnung eines mit dem Gewindeanschluß der Maske verschraubbaren, als rotationssymmetrischer Hohlkörper ausgebildeten Handrades mit Gewindehülse, das am Innenumfang gleichzeitig als zum Handrad hin trichterförmig erweiterter Haltezylinder zur drehbeweglichen Führung und zur einfachen, schnellen und lagerichtigen Zuführung des Steckanschlusses 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 is the assignment of a screwed with the threaded connection of the mask, designed as a rotationally symmetrical hollow body handwheel with threaded sleeve which is formed on the inner circumference at the same time as the handwheel out funnel-shaped extended retaining cylinder for rotatable guidance and for easy, fast and correct feeding of the connector. The handwheel according to the invention can each be screwed separately with the mask or rotatably held on the lung machine, in both cases easily and quickly a secure connection between the mask and the lung machine can be made.

An die Maske können somit wahlweise mit einem Steck- oder mit 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 be connected either with a plug-in or with a threaded connection provided with lung valves. Now, the advantages of the plug-in connection, namely quick and easy production of the connection and free rotational mobility of the connected via a hose connection to a compressed air reservoir regulator can be used in the widespread respirators with standardized, uniform threaded connection. In fire and rescue operations, mutual assistance is also possible between the users of both different systems.

An das trichterförmige Führungsteil schließt sich das am Außenumfang profilierte Handrad an, das eine schnelle manuelle Schraubverbindung mit der Maske ermöglicht.The funnel-shaped guide part is followed by the handwheel profiled on the outer circumference, which allows a quick manual screw connection with the mask.

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, the circumferential locking groove for receiving the locking lugs 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 connection piece of the regulator to be connected is rotatably mounted on sliding surfaces of the handwheel or the latching groove.

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.Latching device provided on the locking elements are determined by the engagement of the locking lugs in the locking groove, so that the provided with the plug connection regulator is provided with a rotatable handwheel and can be connected by screwing with the mask.

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

Das zylindrisch ausgebildete Gewindeanschlußstück 1, das in bekannter Weise mit einem nicht dargestellten Maskenkörper verbunden ist, weist an der Innenfläche ein bei Atemschutzmasken übliches Normgewinde 2, z.B. M 45 x 3, 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 cylindrically shaped threaded connection piece 1, which is connected in a known manner with a mask body, not shown, has on the inner surface of a customary with respirators normal thread 2, for example M 45 x 3, and a seal 3. With the threaded connection piece 1, a plug-in connection sleeve 4 is screwed with handwheel 16 to serve as a coupling element for a regulator 5 with plug connection part. The plug connection part of the lung machine 5 comprises two radially movable, oppositely arranged locking elements 6 with locking lugs 7, which can be manually displaced inwardly against the action of a compression spring 8 and are pressed 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 corresponding to the standard thread 2 of the threaded connection piece 1 of the mask. The threaded sleeve 11 merges into a funnel-like guide part 13, to which a sliding surface 14 and a circumferential locking groove 15 join. The upper edge of the plug-in connection sleeve 4 forms a hand wheel 16 with an upper sliding surface 17, a Labyrinthnut 18 and a tooth-like stepped outer peripheral surface 19. The inner peripheral surface of the hand wheel 16 is a tapered sliding surface 20th

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 a provided in the usual way with a threaded connection 1 respirator with a regulator 5 with plug connection part to be connected, previously only the handwheel 16 is screwed with plug connection sleeve 4 with its threaded sleeve 11 in the threaded connection piece 1. The threaded sleeve 11 and the threaded connection piece 1 are sealed against each other via the seal 3 and secured in a stable position. Since the plug-in connection sleeve 4 has a hand wheel 16 with a toothed outer peripheral surface 19, it can be quickly and firmly connected to the threaded connection piece 1 and also easily released manually again. The respirator resp. The regulator can thus be quickly changed over from "thread connection mode" to "plug connection mode" (or vice versa).

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 done in no time, since the guide cylinder 9 of the Regulator 5 over the wide opening and the funnel-like guide member 13 as it were by itself in the cylindrically leading support cylinder 11 'of the plug-in connector 4 slides. The locking lugs 7 are shifted with their bevel 7a along the tapered sliding surface 20 of the handwheel 16 by slight manual pressure on the regulator 5 against the action of the compression spring 8 radially inwardly to then lock in the locking groove 15 of the male terminal 4 resiliently. The regulator 5 is now axially immovable, but rotatably on the sliding surfaces 14 and 17, and sealed via the sealing element 10 and radially fixed in the holding cylinder 11 in the plug connector 4. The separation of the regulator 5 of the male connector 4 is made by the locking elements 6 manually pressed inward so that the regulator 5 is unlocked and can be removed. In Fig. 1 For better understanding, the locking element 6 is shown in the left half of the picture in the locked state and in the right half of the picture in the inserted, unlocked state. But the separation can also be done by turning the handwheel 16 and thus unscrewing the plug-in connection sleeve 4 (threaded sleeve 11), so that a component with threaded connection, such as a filter or a regulator with threaded connection, can be screwed into the mask.

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-in connection sleeve 4 and threaded sleeve 11 formed fitting with handwheel 16 thus either a screw or a plug connection with the respirator or the regulator can be made safely and quickly, with the mask depending on the embodiment both overpressure systems as Even normal pressure systems can be connected. That is, all commercially available respirator masks with standard thread connection can be optionally separated at the screw connection or at the plug connection. With the interposition of the plug-in connection sleeve 4 as a plug connection connected regulators 5 are rotatably held on the equipped with a threaded connection piece 1 respirator, so that the mobility of the user's head is not affected in this regard.
