Description

Die Erfindung betrifft ein Atemschutzgerät mit Schutzhaube, entsprechend dem Oberbegriff des Anspruchs l.The invention relates to a breathing apparatus with a protective hood, according to the preamble of claim 1.

Es wird immer wieder bekannt, daß Menschen bei Bränden in z.B. Hotels zu Schaden kommen. Sie finden kein Atemschutzgerät, das auch von Ungeübten aufgesetzt werden kann und dann auch für alle Kopfgrößen, bei Brillenträgern und bei allen Bärten seine Schutzaufgabe erfüllt.It is known again and again that people are caught in fires in e.g. Hotels get damaged. You will not find a respirator that can be put on by inexperienced people and then also fulfills its protective function for all head sizes, for glasses wearers and for all beards.

Ein bekanntes Fluchtfiltergerät mit einer Schutzhaube besitzt, in diese dicht eingearbeitet, einen Atemanschluß in Form einer Halbmaske. Diese Halbmaske nimmt ein Atemfilter in der Ausbildung als CO-Filter auf. Es ist mit seiner Zuluftöffnung außerhalb und der Einatemöffnung innerhalb des Atemanschlusses angeordnet. Die Zuluft- und die Einatemöffnungen sind in der Bereitstellung durch Stopfen verschlossen. Während dieser Bereitstellung ist das Gerät in einem Behälter, bestehend aus einer Rückwand und einem Deckel, untergebracht. Der Stopfen für die Zuluftöffnung ist innen an der Rückwand und der für die Einatemöffnung innen über ein Band an der Schutzhaube befestigt. Mit dem Herausnehmen des Fluchtfiltergerätes aus dem Behälter wird das Atemfilter vom Stopfen an der Rückwand abgezogen und damit die Zuluftöffnung geöffnet und beim Öffnen der Schutzhaube zum Aufsetzen auf den Kopf dann auch der Stopfen aus der Einatemöffnung herausgezogen. Für den Träger wird der im Innern der Schutzhaube an dem Band hängende Stopfen möglicherweise stören. Für die Gesamteinbautiefe des Atemfilters sind die Stopfen außerordentlich ungünstig. Der sperrige Behälter für dieses Gerät ergibt sich aus dessen Gesamtaufbau. (DE-GM 80 15 449)A known escape filter device with a protective hood, tightly incorporated into it, has a breath connection in the form of a half mask. This half mask is used by a breathing filter designed as a CO filter. It is arranged with its supply air opening outside and the inhalation opening inside the breathing connection. The supply air and inhalation openings are closed by plugs. During this deployment, the device is housed in a container consisting of a rear wall and a lid. The plug for the supply air opening is attached to the inside of the rear wall and the plug for the inhalation opening is attached to the protective hood with a band. With the When the escape filter device is removed from the container, the breathing filter is removed from the stopper on the rear wall, thus opening the supply air opening and then when the protective hood is opened to be placed on the head, the stopper is also pulled out of the inhalation opening. For the wearer, the stopper hanging from the belt inside the protective hood may interfere. The plugs are extremely unfavorable for the overall installation depth of the breathing filter. The bulky container for this device results from its overall structure. (DE-GM 80 15 449)

Aufgabe der Erfindung ist ein möglichst wenig sperriges Atemschutzgerät mit Schutzhaube, dessen Filter in der Bereitstellung verschlossen ist, mit dem Aufsetzen der Schutzhaube jedoch für die Beatmung geöffnet ist.The object of the invention is the least possible bulky respirator with protective hood, the filter of which is closed in the provision, but is open for ventilation when the protective hood is put on.

Die Lösung der Aufgabe erfolgt gemäß dem Kennzeichen des Anspruchs 1. Vorteilhafte Weiterbildungen sind in den Ansprüchen 2 und 3 beschrieben.The problem is solved according to the characterizing part of claim 1. Advantageous further developments are described in claims 2 and 3.

Atemschutzgeräte mit Schutzhaube dienen im wesentlichen als Rettungsgeräte, wie z.B. als Fluchtgeräte. Sie müssen dazu leicht greifbar und dann auch von Ungeübten aufsetzbar sein. Das erfüllt das Atemschutzgerät nach der Erfindung in hervorragender Weise. Es ist von seinem Aufbau her leicht und sichtbar unterzubringen. Es muß dazu nur in einem Außenbeutel deutlich aufgehängt sein. Das in seinem Verpackungsbeutel in der Halbmaske befindliche Atemfilter ist damit so sicher verschlossen, daß es dann im Katastrophenfall funktionsbereit zur Verfügung steht. Mit dem Auffalten der Schutzhaube öffnet das Atemfilter sich selbstverständlich. Ein Aufsetzen mit versehentlich nicht geöffnetem Filter ist nicht möglich.Respiratory protective devices with a protective hood essentially serve as rescue devices, such as escape devices. To do this, they must be easy to grasp and then be put on by inexperienced people. The breathing apparatus according to the invention fulfills this in an outstanding manner. Its structure makes it easy and visible to accommodate. It only has to be clearly hung in an outer bag. The breathing filter in the packaging in the half mask is so securely closed that it is then ready for use in the event of a disaster. Of course, when you open the protective hood, the breathing filter opens. It is not possible to put it on with the filter accidentally not opened.

Die verschiedenen Halterungen am Verpackungsbeutel und der Schutzhaube sichern den richtigen Einbau des Atemfilters. Es kann damit nicht falsch herum hineingesteckt werden. Der Austausch des Atemfilters kann z.B. nach Übungen mit dem Atemschutzgerät notwendig werden.The various brackets on the packaging bag and the protective hood ensure the correct installation of the breathing filter. It cannot be inserted the wrong way round. Replacing the breathing filter can e.g. after exercises with the breathing apparatus.
