Abstract

An air escape filter apparatus for emergency use by a person comprises a filter which is contained within a filter housing which is accommodated within a half mask portion of a breathing mask which is adapted to be engaged over the nose and mouth of a person. The half mask portion includes a sleeve portion having a guide ring which engages over the filter housing and is shiftable along the filter housing while remaining in holding engagement therewith. The filter housing is of a size so that it is retainable within the half mask portion in a standby condition at which time it is substantially coextensive in length with the half mask portion so that the two elements are accommodated within a very small space. The filter is extensible at the end of the sleeve portion to free the interior of the half mask for engagement over the wearer's face in a ready condition.

Description

Die Erfindung betrifft ein Fluchtfiltergerät nach dem Oberbegriff des Anspruchs 1.The invention relates to an escape filter device according to the preamble of claim 1.

Es wird immer wieder bekannt, daß Menschen bei Bränden in z.B. Hotels zu Schaden kommen. Einfache, griffbereite Fluchtfilter würden die Rettung erleichtern. Derartige Fluchtgeräte werden nur dann an der Person mitgetragen und sind aber immer zur Hand, wenn sie im Gepäck leicht zu verstauen sind. Sie dürfen daher nur einen kleinstmöglichen Raum einnehmen.It is known again and again that people are caught in fires in e.g. Hotels get damaged. Simple, handy escape filters would make rescue easier. Escape devices of this type are only carried on the person and are always at hand if they are easy to stow in the luggage. You are therefore only allowed to occupy the smallest possible space.

Bekannt ist ein Fluchtfiltergerät mit Schutzhaube, untergebracht in einem Behälter. In eine Schutzhaube ist der Atemanschluß einer Halbmaske dicht eingearbeitet. Die Halbmaske nimmt ein Atemfilter auf. In der Bereitstellung ist das Fluchtfiltergerät in einem Bereitschaftsbehälter untergebracht. Eine niedrige Bauhöhe wird durch eine entsprechende Faltung der Schutzhaube und Zurückstülpen des Gesichtsrandes über das Atemfilter erreicht. (DE-GM 82 04 996.3) Das Zurückstülpen des Gesichtsrandes der Halbmaske über das Atemfilter hinweg, als Voraussetzung für die niedrige Bauhöhe, stellt eine sehr starke Belastung dar und verlangt, vor allem auch wegen der möglichen langen Bereitschaftszeit, ein ausgesuchtes Maskenmaterial.An escape filter device with a protective hood, housed in a container, is known. The breathing connection of a half mask is tightly worked into a protective hood. The half mask holds a breathing filter. In the preparation, the escape filter device is accommodated in a standby container. A low overall height is achieved by folding the protective hood and pulling the edge of the face back over the breathing filter. (DE-GM 82 04 996.3) Pushing the face edge of the half mask back over the breathing filter as a prerequisite for the low overall height places a very heavy load represents and requires, especially because of the possible long standby time, a selected mask material.

Es ist ein weiteres Fluchtfiltergerät mit einer Halbmaske und einem Atemfilter bekannt geworden, mit der die Aufgabe nach der geringen Bauhöhe durch eine besondere Gestaltung der Halbmaske gelöst werden soll. Hier ist das Atemfilter an eine faltbare Halbmaske angeschlossen. Dazu besteht die Halbmaske aus einem Gesichtsrahmen und einem schlauchförmigen faltbaren Verbindungsstück zum Atemfilter. Im niedrigen Behälter ist das Verbindungsstück zusammengefaltet, so daß der Gesichtsrahmen entweder direkt auf dem Atemfilter aufliegt,oder aber der Gesichtsrahmen ist derart ausgebildet, daß er sich über das Atemfilter schieben läßt. (DE-GM 82 24 371.9)Another escape filter device with a half mask and a breathing filter has become known, with which the task is to be solved by a special design of the half mask due to the low overall height. Here the breathing filter is connected to a foldable half mask. For this purpose, the half mask consists of a face frame and a tubular, foldable connecting piece to the breathing filter. In the low container, the connector is folded up so that the face frame either lies directly on the respiratory filter, or the face frame is designed such that it can be pushed over the respiratory filter. (DE-GM 82 24 371.9)

Aufgabe der Erfindung ist ein Fluchtfiltergerät mit einem Atemfilter in einer Halbmaske, die beide mit niedrigster Einbauhöhe zur Unterbringung den kleinstmöglichen Behälter benötigen.The object of the invention is an escape filter device with a breathing filter in a half mask, both of which require the smallest possible container with the lowest installation height for accommodating.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das über das Atemfilter passende Gesichtsteil in einem Führungsteil verlängert ist und an seinem Ende innen einen Führungsring, auf dem Atemfilter gleitend, enthält und in einem Anschlag, der den Filtereingang umgreift, endet.This object is achieved in that the face part fitting over the respiratory filter is extended in a guide part and at its end contains a guide ring on the inside, sliding on the respiratory filter, and ends in a stop that encompasses the filter inlet.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß in einer sehr einfachen neuen Ausbildung der bekannten Halbmasken unter Beibehaltung von deren Vorteilen, die sie gegenüber den bekannten Mundstücken mit der notwendigen Nasenklammer besitzt, eine äußerst niedrige Einbauhöhe entsteht. Diese wird nur durch die Atemfilterbauhöhe bestimmt. Der Führungsring für das Atemfilter in dem Führungsteil der Halbmaske sichert zusammen mit dem Anschlag einen stabilen Halt desselben. Dem Träger des Fluchtfiltergerätes wird damit eine bequeme Trageweise in einer sonst kritischen Situation gesichert. Bei hindurchgeschobenem Filter wirkt der Anschlag als weitere Abdichtung.The advantages achieved with the invention are in particular that in a very simple new Training of the known half-masks while maintaining their advantages, which it has compared to the known mouthpieces with the necessary nose clip, an extremely low installation height arises. This is only determined by the height of the breathing filter. The guide ring for the breathing filter in the guide part of the half mask, together with the stop, ensures a stable hold of the same. The wearer of the escape filter device is thus ensured a comfortable way of wearing in an otherwise critical situation. When the filter is pushed through, the stop acts as a further seal.

Die zusätzliche Ausrüstung mit einer Schutzhaube ermöglicht den Einsatz auch unter besonders kritischen Verhältnissen.The additional equipment with a protective hood enables use even under particularly critical conditions.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden beschrieben. Es zeigen

  • Fig. 1 das Fluchtfiltergerät im Einbauzustand,
  • Fig. 2 das Fluchtfiltergerät im Benutzungszustand.
An embodiment of the invention is shown in the drawing and is described below. Show it
  • 1 the escape filter device in the installed state,
  • Fig. 2 shows the escape filter device in use.

Das Fluchtfiltergerät besteht aus einem Atemfilter 1, das dicht an eine Halbmaske 2 angeschlossen ist. Die Halbmaske 2 ist aus einem Gesichtsteil 3, das sich über das Atemfilter 1 schieben läßt, und einem Balg 4 aufgebaut. Über den weichen Balg 4 ist die Halbmaske 2 mittels einer Schelle 5 zum Filterausgang 6 hin befestigt.The escape filter device consists of a breathing filter 1, which is connected tightly to a half mask 2. The half mask 2 is made up of a face part 3, which can be pushed over the breathing filter 1, and a bellows 4. The half mask 2 is fastened to the filter outlet 6 by means of a clamp 5 over the soft bellows 4.

Das Gesichtsteil 3 ist in einem Führungsteil 7 fortgesetzt, mit dem das Atemfilter bis zum Filtereingang 8 umfaßt wird. Das Führungsteil 7, das zum anderen Ende hin einen Führungsring 9 enthält, endet in einem Anschlag 10. Der Anschlag 10 begrenzt den Weg des Atemfilters 1. Der Führungsring 9 besitzt einen Durchmesser, mit dem ein leichtes Hindurchschieben des Atemfilters 1 ermöglicht wird. Eine Kopfbänderung 11 wird mittels einer Schelle 12 über dem Führungsteil 7 und dem Führungsring 9 gehalten. Es kann dabei in besonderer Ausbildung des Fluchtfiltergerätes auch gleichzeitig eine Schutzhaube 13 gehalten werden.The face part 3 is continued in a guide part 7, with which the breathing filter is embraced up to the filter inlet 8. The guide part 7, which contains a guide ring 9 towards the other end, ends in a stop 10. The stop 10 limits the path of the breathing filter 1. The guide ring 9 has a diameter with which the breathing filter 1 can be easily pushed through. A head strap 11 is held by means of a clamp 12 over the guide part 7 and the guide ring 9. In a special design of the escape filter device, a protective hood 13 can also be held at the same time.

Im Benutzungszustand nach der Fig. 2, hier mit der Schutzhaube 13, ist das Atemfilter 1 von innen her durch das Führungsteil 7 und den Führungsring 9 hindurchgeschoben. Die Begrenzung erfolgt dabei mit dem Anstoß der Schelle 5 an den Führungsring 9. Der Anschlag 10 aus dem bekannten elastischen Material der Atemmasken legt sich dabei um den Atemfiltermantel 15 und gibt damit zusammen mit dem Führungsring 9 beim Tragen des Fluchtfiltergerätes dem Atemfilter 1 den nötigen Halt.2, here with the protective hood 13, the breathing filter 1 is pushed from the inside through the guide part 7 and the guide ring 9. The limitation takes place with the abutment of the clamp 5 on the guide ring 9. The stop 10 made of the known elastic material of the breathing masks is placed around the breathing filter jacket 15 and, together with the guide ring 9, thus gives the breathing filter 1 the necessary support when the escape filter device is worn .
