Description

Einrichtung zur Belüftung von Schutzanzügen gegen chemische Kampfstoffe Die Erfindung betrifft eine Einrichtung zur Belüftung von Schutzanzügen gegen chemische Kampfstoffe mittels eines Frischluftatemschutzgerätes. Bei einer bekannten Einrichtung dieser Art sind zwei Luftzuführun.gsschläuclie angeordnet, von denen der eine zur Zuführung der Atemluft in die den Kopf des Trägers umschließende Haube und der andere zur Einführung von Luft in den Anzug dient. Bei dieser bekannten Einrichtung besteht zwischen dem Innern der Haube und dem Innern des Anzuges keine Verbindung.Device for ventilation of protective suits against chemical warfare agents The invention relates to a device for ventilating protective suits against chemicals Warfare agents using a fresh air breathing apparatus. At a known facility of this type, two Luftzuführun.gsschläuclie are arranged, one of which for Supply of the breathing air into the hood surrounding the head of the wearer and the other is used to introduce air into the suit. In this known device there is no connection between the inside of the hood and the inside of the suit.

Bei einer anderen hekannten Einrichtung der genannten Art, bei der ebenfalls getrennte Luftzuführungsschläuclie für die Atemluft und die Luft zur Belüftung des An-, zages .vorluznden sind, steht das Innere der Haube mit dem Innern des Anzuges in offener Verbindung. Diese bekannte Einrichtung hat jedoch den Nachteil, daß der schädliche Atemraum verhältnismäßig groß ist. Den gleichen Nachteil besitzt auch eine zum Kühlen eines Schutzanzuges di-en@ende Einrichtung, bei der die Luft auf der Rückseite des Anzuges eingeleitet und durch Öffnungen, die vor den Augen des Gerätträgers in der Kopfbedeckung angeordnet sind, wieder abgeführt wird.In another known establishment of the type mentioned, in which also separate air supply hoses for breathing air and air for ventilation The inside of the hood matches the inside of the suit in open connection. However, this known device has the disadvantage that the harmful breathing space is relatively large. Has the same disadvantage a device serving to cool a protective suit in which the air rises the back of the suit and introduced through openings that are in front of the eyes of the Device wearer are arranged in the headgear, is removed again.

Demgegenüber bezweckt die Erfindung, eine Einrichtung zur Belüftung von Schutzanzügen gegen chemische Kampfstoffe zu schaffen, bei der nur ein Luftzuführungsschlauch erforderlich ist und bei der außerdem der schädliche Atemraum möglichst klein ist.In contrast, the invention aims to provide a device for ventilation of creating protective suits against chemical warfare agents with only one air supply hose is necessary and in which the harmful breathing space is also as small as possible.

Die Erfindung besteht darin, daß der Luftzuführungsschlauch an die zum Schutzanzug gehörige Gasschutzmaske angeschlossen ist und daß die Gasschutzmaske mit einem in bekannter Weise ventilklappenartig wirkenden elastischen Dichtrand versehen und derart mit dem Schutzanzug verbunden ist, daß der nicht zum Atmen notwendige Teil der in die Gasschutzmaske einströmendien Luft unter dem veiitilklapp"nartig wirkenden Dichtrand der Maske hindurch in den mit Entlüftungsventilen versehenen Schutzanzug einströmt.The invention consists in that the air supply hose to the The protective gas mask belonging to the protective suit is connected and that the protective gas mask with an elastic sealing edge which acts like a valve flap in a known manner and is connected to the protective suit in such a way that it is not necessary for breathing Part of the air flowing into the gas mask is located under the valve-like flap acting sealing edge of the mask through in the provided with ventilation valves Protective suit flows in.

Eine solche Einrichtung weist gegenüber den bekannten Einrichtungen den Vorteil auf, daß sie wesentlich einfacher ausgebildet und daher auch billiger herzustellen ist. Die Frischluft wird lediglich in die Maske eingeführt, aus der sie unter dem ventilklappenartig wirkenden Dichtrand hindurch in das Innere des Anzuges gelangt, den sie belüftet und aus dem sie durch die Rückschlagventile wieder entweicht. Infolge der Anordnung des ventilklappenartig wirkenden Dichtrandes ist der schädliche Raum unter der Maske sehr klein.Such a device has compared to the known devices the advantage that they are made much simpler and therefore cheaper is to be established. The fresh air is only introduced into the mask from which they pass under the valve flap-like sealing edge into the interior of the Suit, which it ventilates and from which it again through the non-return valves escapes. As a result of the arrangement of the sealing edge, which acts like a valve flap, is the harmful space under the mask is very small.

In der Zeichnung sind zwei Ausführungsformen des Erfindungsgegenstandes dargestellt.In the drawing are two embodiments of the subject matter of the invention shown.

Abb. r zeigt die Belüftungseinrichtung in Verbindung mit einem feststehenden und Abb.2 die Einrichtung in Verbindung mit einem frei tragbaren Frischluftatemschutzgerät. Der mit dem ventilklappenartig wirkenden elastischen Dichtrand b versehenen Maske a wird die zum Atmen und zutn Belüften dienende Luft durch den Schlauch e zugeführt. Die überschüssige Luft entweicht unter dem ventilklappenartig wirkenden Dichtrand b hindurch in den Schutzanzug c, den sie durch die Entlüftungsventile d wieder verläßt. Die ausgeatmete Luft kann ebenfalls unter dem Dichtrand b hindurch in den Schutzanzug entweichen. Es kann aber auch ein besonderes, mit einer verhältnismäßig starken Feder versehenes Ausatemventil f angeordnet sein, das nur einen kleinen Teil der zugeführten und der ausgeatmeten Luft abführt und zugleich als Sicherheits- und Spülventil dient.Fig. R shows the ventilation device in connection with a fixed and Fig. 2 the device in connection with a freely portable fresh air breathing apparatus. The mask a , which is provided with the elastic sealing edge b acting like a valve flap, is supplied with the air used for breathing and ventilation through the hose e. The excess air escapes under the sealing edge b, which acts like a valve flap, into the protective suit c, which it leaves again through the vent valves d. The exhaled air can also escape under the sealing edge b into the protective suit. However, a special exhalation valve f provided with a relatively strong spring can also be arranged, which removes only a small part of the supplied and exhaled air and at the same time serves as a safety and flushing valve.
