Description

Sprengring zur Befestigung der Klarscheibe in dem Fenster einer Gasschutzmaske. Um die das Fenster trübenden Feuchtigkeitsniederschläge in Gasschutzmasken zu vermeiden., verweset man bekanntlich sogenanate Klarscheiben, die keine Trübung annehmen. Diese Klarscheiben werden in der Regel von innen her dein Feinster angefügt und mit Hilfe eines gleichoeitig die Abdichtung zwischen Fenster und Klarscheibe übernehmenden Sprengringes festgehalten. Wird letzterer aus Stahl- oder Bronzedlraht gefertigt, so ist seine Handhabung schwierig, insbesondere ist -er schlecht herauszunehmen. Auch ist die federnde Kraft solcher Drahtringe keine günstige.Snap ring for fastening the clear pane in the window of a gas mask. In order to avoid the condensation of moisture in gas protective masks, which cloud the window., It is well known that so-called clear panes that do not take on cloudiness are put to rot. These Clear panes are usually attached from the inside of your finest and with help one on the same side that takes over the seal between the window and the clear pane Snap ring held. If the latter is made of steel or bronze wire, so it is difficult to handle, in particular, it is difficult to take out. The resilient force of such wire rings is also not favorable.

Gegenstand der Erfindung ist ein, diese Nachteile vermeidender federnder Sprengring. Er ist aus einem U- oder V-förmigen Streifen gebildet, dessen Schenkel nach innen gerichtet sind. Dieser Sprengring kann bequem mit den Fingernägeln erfaBt und zum Zwecke des Auswechselas der Klarscheibe herausgenommen werden. Auch ist seine Federkraft trotz geringen Gewichts und- Materialverbrauchs so günstig, daß sich Üi drer Regel ein besonderes Abdicht.ungsmatürial für die Klarscheibe erübrigt.The subject of the invention is a resilient snap ring which avoids these disadvantages. It is formed from a U- or V-shaped strip, the legs of which are directed inwards. This snap ring can easily be grasped with the fingernails and removed for the purpose of changing the clear disk. In spite of the low weight and material consumption, its spring force is so favorable that a special sealing material for the clear pane is usually unnecessary.

Die Zeichnung veranschaulicht zwei Ausführvttv6-sbeispiel,e der Erfindung. Ab.b. r ist eine Ansicht der Gasmaske. Abb.2 und 3 stellen einen V-förmigen Sprengring in Schnitt und Draufsicht dar. Abb. ¢ und , zeigen einen U-förmigen Sprengring im Schnitt und Draufsicht. Abb. 6 ist ein Schnitt durch ein Fenster mit Klarscheibe Lund eingelegtem U-förmigen Sprengring und Abb.7 eitle Innenansicht des Fensters nach Abb.6.The drawing illustrates two examples of embodiments of the invention. Fig. r is a view of the gas mask. Figures 2 and 3 represent a V-shaped snap ring in section and top view. Fig. ¢ and, show a U-shaped snap ring in Section and top view. Fig. 6 is a section through a window with a clear pane Lund inlaid U-shaped snap ring and Fig. 7 a vain interior view of the window according to figure 6.

Wie aus den Abb. 2 bis 5 ersichtlich, besitzt jede der beiden dargestellten Ausführungsformen des Sprengringes am Innenumfang eine ringrumlaufende Nut, die das Anheben des Ringes mit den Fingernägeln -ermöglicht, wenn dieser mach Abb. 6 in das Fenster eingelegt ist. Letzteres besteht aus einem napfförmigen Körper r aus Glas oder seinem -durchsichtigem., biegsamen Plattenmaterial, wie Zellon, Zellborn o. dgl., gegen dessen ebene Fläche 2 die Klarscheibe 3 gelegt ist. Letztere wird durch dien Sprengring ¢ festgehalten, der gleichzeitig in Zusammenwirken mit dem nach einwärts umgestülpten Rande dies Fensters r die Abdichtung zwischen Fenster r Zünd' Klarscheibe 3 nimmt, so daß keime Feuchtigkeit zwischen beide eindringen kann.As can be seen from Figs. 2 to 5, each of the two has shown Embodiments of the snap ring on the inner circumference have a circumferential groove that the ring can be lifted with the fingernails if this is done Fig. 6 is inserted in the window. The latter consists of a cup-shaped body r made of glass or its transparent., flexible plate material, such as Zellon, Zellborn or the like, against the flat surface 2 of which the clear pane 3 is placed. The latter will held in place by the snap ring ¢, which simultaneously interacts with the the inwardly turned-over edge of this window r the seal between the windows r Zünd 'clear disc 3 takes so that germs moisture penetrate between the two can.
