Werkzeug zum gleichzeitigen Herausnehmen der Klarscheiben und Sprengringe aus der Augenglasfassung von Gasschutzmasken Das Herausnehmen der Klarscheiben und der sie haltenden Sprengringe .aus den Augenglasfassungen der S-Maske bietet für den Maskenträger keine -Schwierigkeiten. Anders ist es aber, wenn ein Gerätewart diese Tätigkeit stundenlang ausüben muß. Da der Gerätewart hierbei dauernd hinter die scharfkantigen Rasten der Sprengringe greifen muß, um diese aus der Augenglasfassung herauszuziehen, kann es zu Verletzungen der Fingerspitzen kommen. Ebenso ist das Herausnehmen der Klarscheiben mittels der Finger auf die Dauer umständlich und zeitraubend.Tool for removing the clear disks and snap rings at the same time from the eyeglass frame of gas masks Removing the clear panes and of the snap rings holding them .from the eyeglass frames of the S-mask provides for the mask wearer no difficulties. It is different, however, when there is an equipment attendant must do this activity for hours. Since the machine operator is always behind the sharp-edged catches of the snap rings must grip to remove them from the eyeglass frame pulling it out may injure your fingertips. It is the same Removing the clear panes with your fingers is cumbersome and time-consuming in the long run.

Gemäß der Erfindung sollen diese Nachteile durch ein Werkzeug behoben werden, welches zwei in die Rasten des Sprengringes einsetzbare und mit hakenartigen Fortsätzen versehene, um ein Gelenk mittels Handgriffe spreizbare Dorne und seitlich des Gelenkes einen gelenkig aufgehängten Saugnapf aufweist.According to the invention, these disadvantages are to be remedied by a tool be, which two can be inserted into the notches of the snap ring and with a hook-like Projections provided, spines spreadable around a joint by means of handles and laterally of the joint has an articulated suction cup.

Vorzugsweise sind die Handgriffe durch Federspannung derart gespreizt gehalten, daß die hakenförmigen Fortsätze der Dorne in Ruhestellung des Werkzeuges in der Entfernung der Rasten des in die Augenglasfassung eingelegten Sprengringes stehen.The handles are preferably spread apart in this way by spring tension held that the hook-shaped extensions of the mandrels in the rest position of the tool in the removal of the notches of the snap ring inserted in the eyeglass frame stand.

Mittels eines solchen Werkzeuges ist ein schnelles und leichtes Herausnehmen der Sprengringe unter gleichzeitigem Entfernen der Klarscheiben aus der Augenglasfassung möglich.Such a tool can be removed quickly and easily the snap rings while removing the clear lens from the eyeglass frame possible.

In der Zeichnung ist ein Ausführungsbeispiel des Werkzeuges schaubildlich dargestellt.The drawing shows an exemplary embodiment of the tool shown.

Die Dorne i sind mit hakenförmigen Fortsätzen 2 versehen und um ein Gelenk q. mittels der Handgriffe 3 spreizbar. Die Handgriffe 3 stehen unter der Spannung von Federn 5. Seitlich des Gelenkes ¢ ist en Saugnapf 6 an einem Gelenk 7 angeordnet, Die Wirkungsweise des Werkzeuges ist folgende: Das Werkzeug wird zum Gebrauch mit den hakenartigen Fortsätzen 2 in die Rasten des Sprengringes eingeführt, und zugleich wird -der Saugnapf 6 mit geringem Druck auf die Klarscheibe .aufgesetzt. Durch Zusammendrücken der Handgriffe 3 gegen die Spannung der Federn 5 werden die Dorne i gespreizt. Hierdurch wird der Sprengring aus seiner Lage entfernt. Die Klarscheibe bleibt an denn Saugnapf 6 hängen.The mandrels i are provided with hook-shaped projections 2 and around a Joint q. expandable by means of the handles 3. The handles 3 are under the Tension of springs 5. On the side of the joint ¢ is a suction cup 6 on a joint 7 arranged, the mode of action of the tool is as follows: The tool is used to Use with the hook-like extensions 2 inserted into the notches of the snap ring, and at the same time the suction cup 6 is placed on the clear pane with little pressure. By compressing the handles 3 against the tension of the springs 5, the Thorns i spread. This removes the snap ring from its position. The clear disk remains on the suction cup 6.
