Description

Sauerstoffatemschutz-,erät Gegenstand des Patents 620 138 ist ein Sauerstoffatemschutzgerät mit einem den Gebrauch des Gerätes bei nicht geöffnetem Sauerstoffvorratsbehälter verhindernden Glied. Dieses Glied ist ein für den gewöhnlichen Betrieb des Atemschutzgerätes notwendiger Teil, der erst dann in die die Benutzung des Atemschutzgerätes ermöglichende Betriebsstellung gebracht werden kann, wenn das Absperrventil des Sauerstoffvorratsbehäl: ters geöffnet worden ist. Zu diesem Zweck kann bei nicht geöffnetem Sauerstoff vorratsbehälter der Atemsack aufgerollt und von einem mit dem Handrad des Absperrventils des Sauerstoffvorratsbehälters verbundenen, z. B. aus einer Kette bestehenden Sperrglied umschlossen sein, das erst dann gelöst werden kann, wenn das Handrad des Absperrventils des Sauerstoffvorratsbehälters in die Offenstellung gedreht worden ist.Oxygen respirator, the subject of patent 620 138 is an oxygen respirator with a device preventing the use of the device when the oxygen supply container is not open. This link is a part that is necessary for normal operation of the breathing apparatus and can only be brought into the operating position that enables the use of the breathing apparatus when the shut-off valve of the oxygen reservoir has been opened. For this purpose, when the oxygen storage tank is not open, the breathing bag can be rolled up and connected to the handwheel of the shut-off valve of the oxygen storage tank, e.g. B. be enclosed from a chain existing locking member, which can only be released when the handwheel of the shut-off valve of the oxygen reservoir has been turned into the open position.

Die Erfindung betrifft nun eine weitere Ausbildung eines solchen Sauer stoffatemschutzgerätes und besteht darin. daß das den Gebrauch des Gerätes bei nicht geöffnetem Absperrventil des Sauerstoffvorratsbehäl.ters, verhindernde Glied ein am Betätigungsglied des Absperrventils angebrachter Teil, z. B. ein Stab, ist, der bei geschlossenem Absperrventil gegen den Körper des Gerätträgers drückt. Hierdurch wird mit einfachen Mitteln erreicht, daß der Gerätträger das Öffnen des Absperrventils des Sauerstoffvorratsbehälters nicht vergißt.The invention now relates to a further embodiment of such a Sauer breathing apparatus and consists of it. that the use of the device is not open shut-off valve of the oxygen storage tank, preventive element part attached to the actuator of the shut-off valve, e.g. B. a rod, is the presses against the body of the wearer when the shut-off valve is closed. Through this is achieved with simple means that the device carrier opens the shut-off valve of the oxygen storage tank.

Die neue Vorrichtung ist besonders für Fluchtgeräte bestimmt, da diese im Aufbau einfach und in der Herstellung billig sein müssen. Umständliche Warnsignale sind infolgedessen nicht verwendbar. Außerdem handelt es sich häufig um Spülgeräte, bei denen die Ausatemluft durch ein Ventil entweicht. also nicht regeneriert wird. Der Sauerstoff wird mittels eines lungengesteuerten Sauerstoffzuführungsventils je nach Bedarf unmittelbar dem oder den Sauerstoffbehältern entnommen. Man kann also mit der Ausatemluft kein Warnsignal. betreiben.The new device is particularly intended for escape devices, as these must be simple in construction and inexpensive to manufacture. Cumbersome warning signs as a result, cannot be used. In addition, it is often a question of dishwashing devices, in which the exhaled air escapes through a valve. so is not regenerated. The oxygen is supplied by means of a lung-controlled oxygen supply valve taken directly from the oxygen tank or tanks as required. One can so with the exhaled air no warning signal. operate.

In der Zeichnung ist ein Ausführungsbeispiel der neuen Vorrichtung dargestellt. Am Befestigungsglied !z des Absperrventils i des in einem Traggehäusen untergebrachten Sauerstoffvorratsbehälters d ist ein Stab m angeordnet, der bei geschlossenem Absperrventil e gegen den Körper des Gerätträgers drückt. Dadurch wird dieser daran erinnert, das Sauerstoffzuführungsventil zu öffnen. In geöffnetem Zustande nimmt der Stab m die mit gestrichelten Linien angedeutete Stellung ein.In the drawing, an embodiment of the new device is shown. On the fastening member! Z of the shut-off valve i of the oxygen storage container d accommodated in a support housing, a rod m is arranged which, when the shut-off valve e is closed, presses against the body of the device carrier. This will remind them to open the oxygen supply valve. In the open state, the rod m assumes the position indicated by dashed lines.
