  Mundanschlussstück für Atemmasken. 



   Es ist bekannt, an den Mundanschlussstücken für Atemmasken, die zum Anschlusse von Filtereinsätzen oder Sauerstoffgeräten dienen, ein Einatmungs- und ein Ausatmungsventil oder wenigstens das eine dieser beiden Atemventile anzubringen. 



   Vorliegende Erfindung besteht darin, bei   Mundanschlussstücken,   bei denen die Verschraubung der Maske mit dem   Mundanschlussstück   durch eine durch das letztere hindurchgeführte Schraube und ein in der Mundöffnung der Maske vorgesehenes, in einer Brücke eines Mundringes angeordnetes Gegengewinde erfolgt (sogenannter   Zentralgewindeanschluss),   die Kupplungssehraube zugleich als Atemventil auszubilden. Hiedurch wird gegenüber der Anordnung besonderer Atemventile eine wesentliche Vereinfachung und Raum-sowie Materialersparnis erzielt. 



   Die Zeichnung veranschaulicht die Erfindung an einem Ausführungsbeispiel. Fig. 1 zeigt einen 
 EMI1.1 
 dass er am   Schlauche   (aussen) entlang fliesst. Jedenfalls kann er nicht die Kleidung des Maskenträgers beschmutzen, wie es unvermeidlich ist bei Anordnung des Ventils unter der Kupplung. 



   PATENT-ANSPRÜCHE :
1. Mundanschlussstück für Atemmasken, bei dem eine hindurchgeführte Kupplungsschraube mit einem in der Mundöffnung der Maske mit Brücke und Kupplungsgewinde vorgesehenen Ring verschraubt werden kann, dadurch gekennzeichnet, dass die Kupplungssehraube (e) zugleich als Atemventil ausgebildet ist.

  Mouth connector for breathing masks.



   It is known to attach an inhalation and an exhalation valve or at least one of these two breathing valves to the mouth connectors for breathing masks which are used to connect filter inserts or oxygen devices.



   The present invention consists in the fact that, in the case of mouth connectors in which the screw connection of the mask to the mouth connector is carried out by a screw passed through the latter and a mating thread (so-called central thread connector) provided in the mouth opening of the mask and arranged in a bridge of a mouth ring (so-called central thread connector), the coupling tube also acts as a Train breathing valve. As a result, compared to the arrangement of special breathing valves, a significant simplification and space and material savings are achieved.



   The drawing illustrates the invention using an exemplary embodiment. Fig. 1 shows a
 EMI1.1
 that it flows along the hose (outside). In any case, it cannot soil the clothing of the mask wearer, as is inevitable when the valve is arranged under the coupling.



   PATENT CLAIMS:
1. Mouth connector for breathing masks, in which a coupling screw passed through can be screwed to a ring provided in the mouth opening of the mask with a bridge and coupling thread, characterized in that the coupling tube (s) is also designed as a breathing valve.
