Abstract

The connections for over-pressure appliances to breathing masks are subject to a regulation that they must be exchangeable for alternating units. The advantages of the known and proven plug-in connections are to be retained. For this purpose, the connections, which in combination with the appliance parts form a screw connection to the breathing mask, are further separable or connectable in themselves by means of a coupling. This takes the form of a plug-in connector in each case which is retained in a locked and unlockable manner in a screw connection which then possesses the appropriate threaded connection to the breathing mask. <IMAGE>

Description

Die Erfindung betrifft einen Geräte-Schnellanschluß für Atemschutzmasken nach dem Oberbegriff des Anspruchs 1.The invention relates to a quick connector for respirators according to the preamble of claim 1.

Die Anschlüsse für Überdruckgeräte unterliegen einer Regelung, sie müssen für den Einsatz austauschbar sein. Es handelt sich dabei um Schraubanschlüsse. Die Vorteile der bekannten und bewährten Steckanschlüsse, nach denen schnelles und doch sicheres Anschließen der Atemgeräte möglich ist, sollten erhalten bleiben.The connections for overpressure devices are subject to regulation, they must be interchangeable for use. These are screw connections. The advantages of the well-known and proven plug connections, according to which quick and safe connection of the breathing apparatus is possible, should be retained.

Bei einem bekannten Anschluß für ein Atemgerät ist die Verbindung zwischen dem Anschluß der Atemschutzmaske und einem lungengesteuerten Ventil durch eine Steckkupplung mit einer Schnellverriegelung hergestellt. Das Anschlußstück der Atemschutzmaske nimmt das Ende des Anschlußrohres auf, das dort über eine Dichtung mittels eines federnden Halterungsbügels gehalten wird. Der federnde Halterungsbügel rastet dabei in eine Nut des Anschlußrohres ein und sichert die Verbindung der Kupplungsteile. Nachteilig ist, daß nur Atemgeräte gepaart werden können, die mit den Teilen dieses Anschlusses versehen sind. Ein direkter Anschluß von Atemgeräten, die Steckanschlüsse besitzen, an die gewohnten Schraubanschlüsse ist nicht möglich. (DE-AS 26 09 034)In a known connection for a breathing apparatus, the connection between the connection of the respiratory mask and a lung-controlled valve is made by a plug-in coupling with a quick lock. The connector of the respirator mask receives the end of the connecting tube, which is held there by a seal by means of a resilient bracket. The resilient bracket snaps into a groove in the connecting pipe and secures the connection of the coupling parts. The disadvantage is that only breathing devices can be paired that are provided with the parts of this connection. A direct connection of breathing devices that have plug connections, to the usual screw connections is not possible. (DE-AS 26 09 034)

Aufgabe der Erfindung ist ein Geräte-Schnellanschluß für Atemschutzmasken, der es ermöglicht, trotz Verwendung der einheitlichen und gewohnten Anschlußgewinde an den Atemschutzmasken auf eine einfache Art und Weise die Vorteile des Schnellverschlusses zu nutzen.The object of the invention is a device quick connector for respirators, which makes it possible to use the advantages of the quick-release fastener in a simple manner despite the use of the uniform and familiar connection thread on the respirator.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. In einfachster Weise wird es durch Teilung des Anschlusses des Geräteteiles an die Atemschutzmaske, der mittels des genormten Gewindes erfolgt, durch eine leicht zu verbindende und trennende Steckkupplung weiterhin möglich, die Vorteile einer derartigen Kupplung zu nutzen. Sie liegen in der inzwischen allseitig anerkannten Bewährung der Steckanschlüsse.This object is achieved according to the invention by the characterizing features of claim 1. In the simplest way, by dividing the connection of the device part to the respirator mask, which is done by means of the standardized thread, it is still possible to use the advantages of such a coupling by means of an easily connectable and separable plug-in coupling. They are based on the fact that the plug-in connections have now been recognized by all.

Nach weiteren Ausbildungen wird der Gegenstand der Erfindung ausgeweitet, um auch für Verriegelungen anderer Art innerhalb der Kupplung umfassend zu werden und die Benutzung auch während der Bereitschaftszeit vorteilhafter zu machen.According to further developments, the subject matter of the invention is expanded to include other types of locking within the coupling and to make use more advantageous even during the standby time.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden beschrieben.An embodiment of the invention is shown in the drawing and is described below.

Es zeigen

  • Fig. l den Schnellanschluß eines Lungenautomaten an eine Atemschutzmaske in entkuppeltem Zustand,
  • Fig. 2 den Lungenautomaten in Berei tschaftsposition an der Bänderung des Atemschutzgerätes.
Show it
  • 1 shows the quick connection of a regulator to a breathing mask in the uncoupled state,
  • Fig. 2 shows the regulator in standby position on the harness of the respirator.

Eine Atemschutzmaske 1 ist ausgerüstet mit einem Anschlußstück 2, das den normalen Anschluß in Form eines Muttergewindes 3 und einer Dichtung 4 enthält.A respirator 1 is equipped with a connector 2, which contains the normal connection in the form of a nut thread 3 and a seal 4.

Der Schnellverschluß nach der Erfindung besteht aus einem Kupplungsteil Verschraubung 5 aus einem Verschraubungskörper 6 mit einem darauf drehbaren Schraubring 7 und aus einem passenden Steckstutzen 8 fest an einem Geräteteil 14, wie z.B. einem Lungenautomaten.The quick-release fastener according to the invention consists of a coupling part, screw connection 5, of a screw connection body 6 with a screw ring 7 rotatable thereon, and of a suitable plug-in connector 8 fixed to a device part 14, such as, for example, a regulator.

Beide Teile sind im ineinandergesteckten Zustand durch einen Dichtring 9 auf dem Steckstutzen 8 gegeneinander abgedichtet und werden durch einen federnden Sicherungsring 10 miteinander verriegelt. Der Sicherungsring 10 besitzt auf seinem Umfang eine Lücke. Zum Entriegeln und dem folgenden Herausziehen des Steckstutzens 8 aus dem Verschraubungskörper 6 wird der Sicherungsring 10 zusammengedrückt, wodurch ein Sicherungsflansch 11 aus einer Ringnut 12 in dem Verschraubungskörper 6 zurückgezogen und damit die axiale Trennung der Teile ermöglicht wird.Both parts are sealed against each other in the inserted state by a sealing ring 9 on the plug socket 8 and are locked together by a resilient locking ring 10. The locking ring 10 has a gap on its circumference. To unlock and then pull the connector 8 out of the screw body 6, the locking ring 10 is compressed, whereby a locking flange 11 is retracted from an annular groove 12 in the screw body 6 and thus enables the axial separation of the parts.

Beim Verbinden der Teile erfolgt die Verriegelung dadurch, daß der federnde Sicherungsflansch 11, nachdem er über den Sicherungsring 10 zusammengeschoben wurde, in die Ringnut 12 einrastet.When connecting the parts, the locking takes place in that the resilient securing flange 11, after being pushed together via the securing ring 10, engages in the annular groove 12.

Der drehbare Schraubring 7 besitzt an der Anschlußseite zum Anschlußstück 2 der Atemschutzmaske 1 ein passendes Bolzengewinde 13 zum Muttergewinde 3. Mit dem Schraubring 7 auf dem Verschraubungskörper 6 wird die komplette Verschraubung 5 über die Dichtung 4 dicht mit dem Anschlußstück 2 und damit mit der Atemschutzmaske 1 verbunden.The rotatable screw ring 7 has on the connection side to the connection piece 2 of the breathing mask 1 a suitable bolt thread 13 to the nut thread 3. With the screw ring 7 on the screw body 6, the complete screw connection 5 is sealed via the seal 4 with the connection piece 2 and thus with the breathing mask 1 connected.

Der Geräte-Schnellanschluß für die Atemschutzmaske 1 ermöglicht mit dem genormten Gewindeanschluß die Beibehaltung des Steckanschlusses des Schnellanschlusses für die anzukuppelnden Geräteteile 14. Das entkuppelte Geräteteil 14, z.B. ein Lungenautomat, kann durch eine Haltevorrichtung 15 an der Bänderung des zugehörigen Atemgerätes in Bereitschaftsstellung getragen werden.The device quick connector for the respiratory mask 1, with the standardized threaded connector, enables the quick connector to be retained for the device parts 14 to be coupled. The uncoupled device part 14, e.g. a regulator, can be carried by a holding device 15 on the harness of the associated breathing apparatus in the ready position.
