Description

Filteratemschatzeratt insbesondere Filterselbstretter Die Neuerung betrifft ein Filteratemschutzgerät, insbesondere einenFilter-Selbstretter bekannter Art, der einen aus ela- stischem Baustoff bestehenden Ventilkasten besitzt, an dem das Atemmundstück mit angeformt ist. Dieser Ventil'kasten weist einen Bund auf, der dazu geeignet ist, über den Anschlußstutzen des Filtergerätes gestreift zu werden. Da die eigene Spannung des Gummis nicht ausreicht, um den Ventilkasten sicher mit dem Filterteil zu verbinden, ist es notwendig, eine Schelle über den Bund des Ventilkastene zu legen, diese Schelle mit einem Spezialereu zu spannen und ihre Enden gleichzeitig so mzlegen aS ßieimter der erzielten Spannung verbleibt. r Diese Arbeiten werden öfter nicht an der Fertigungsstätte der Geräte vorgenommen, an der solche Spezialwerkzeuge vorhanden sind, sondern es ist aueh notwendig, beim Ersatz eines ver- brauchten Filters gegen ein neues Filter den Austausch durch den Gerätewart des Bergwerkes ornehsen n lassen, in dem Fil- tergeräte eingesetzt sind. 'L'i Es ergibt sich daher die Aufgabe, die Schellenbindung so auszu- bilden, daß zum Anlegen und Spannen der Schelle auf dem Bund des Ventilkastens kein besonders großes Spezialwerkzeug notwendig ist. Filter breath enthusiast especially filter self-rescuers The innovation relates to a filter breathing apparatus, in particular a filter self-rescuer of a known type, which Stischem building material has existing valve box on which the breathing mouthpiece is molded. This valve box has a collar which is suitable for being slipped over the connecting piece of the filter device. Since the rubber's own tension is not sufficient to securely connect the valve box to the filter part, it is necessary to use a clamp to place over the collar of the valve box, this clamp with a special reu to tension and their ends at the same time in this way, as much as the tension achieved remains. r This work is often not carried out at the production site of the devices on which such special tools are available are, but it is also necessary when replacing a needed the filter to replace it with a new one let the equipment attendant of the mine take care of the ter devices are used. 'L'i The task is therefore to design the clamp binding in such a way form that no particularly large special tool is required to apply and tension the clamp on the collar of the valve box.

Die vorliegende Neuerung gibt diese Möglichkeit jedem Gerätewart dadurch, daß zwischen den beiden Enden der Blechachelle ein verformbares Glied angeschaltet ist. Dieses Glied besteht beispielsweise aus einem kurzen Zylinder aus einem kaltverformbaren Werkstoff. An dem Mantel des Zylinders sind zwei Ösen mitangeformt, in die die Enden der Bleohschellen hakenartig eingreifen, Wenn ein Filter des Gerätes durch ein neues ersetzt wer- den soll) kann der Gerätewart die Schelle im zusammengefügten Zu- stand von oben über den Ventilkasten streifen und hat nur nötig, mittels einer Kneifzange den Metallzylinder flachzudrücen. Dadurch wird die Schelle so weit verkürzte daß sie sich eng und mit Spannung an den Bund des aus Gummi bestehenden Ventilkastens anlegt und den Stutzen des Filter sicher festhält.The present innovation gives every device operator this option in that a deformable member is connected between the two ends of the sheet metal frame. This link consists, for example, of a short cylinder made of a cold-deformable material. Two eyelets are molded onto the jacket of the cylinder, into which the ends of the bleo clamps engage like hooks. the should) the equipment attendant can remove the clamp in the assembled stood over the valve box from above and only needs to press the metal cylinder flat with a pair of nippers. As a result, the clamp is shortened to such an extent that it rests tightly and with tension on the collar of the valve box made of rubber and securely holds the nozzle of the filter.

Die Zeichnung stellt ein Ausführungsbeispiel der Neuerung dar.The drawing shows an embodiment of the innovation.

Hier ist 1 der Filterteil 2 der aus Gummi bestehende Ventilkasten des Gerätes mit dem daran angeformten Mundstück 3 und dem Ausatemventil 4. 5 ist die Blechschelle, deren beide Enden in Form von Haken in die Ösen 6 des zylinderförmigen Spannkörpers 7 eingehakt sind. Der Spannkörper mit den Ösen ist in deformiertem Zustand in Abb. 1 der Zeichnung und in nicht deformiertem Zustand in Abb. 2 dargestellt.Here 1 is the filter part 2 the valve box made of rubber of the device with the molded-on mouthpiece 3 and the exhalation valve 4.5 the sheet metal clamp, both ends of which are in the form of hooks in the eyelets 6 of the cylindrical Clamping body 7 are hooked. The clamping body with the eyelets is deformed State shown in Fig. 1 of the drawing and in the undeformed state in Fig. 2.
