Description
Fenster für Gasschutzmasken Die Erfindung betrifft ein Fenster für Gasschutzmasken, dessen Fensterscheibe auf dem mit einem Dichtungsring versehenen Flansch des Fensterrahmens aufliegt.Window for gas protective masks The invention relates to a window for Gas protective masks, the window pane on which is provided with a sealing ring Flange of the window frame rests.
Die Erfindung besteht darin, daß, in den Mantel des Fensterrahmens eine die Fensterscheibe gegen den Dichtring pressende Sicke eingerollt ist.The invention consists in that, in the jacket of the window frame a bead pressing the window pane against the sealing ring is rolled up.
Zwischen der Fensterscheibe und der eingerollten Sicke kann- noch ein Schutzring aus Metall oder Kunststoff eingelegt sein.Between the window pane and the rolled-up bead can still a protective ring made of metal or plastic can be inserted.
Bei Benutzung einer Fensterscheibe aus Glas oder einem anderen spröden, durchsichtigen Baustoff nimmt dieser Schutzring den beim Einrollen der Sicke entstehenden Druck auf und schützt dadurch die Scheibe gegen Zerspringen oder Zerdrücken.When using a window pane made of glass or another brittle, transparent building material, this protective ring takes away the effect of rolling in the bead Pressure on and thereby protects the pane against cracking or crushing.
Es sind zwar bereits Fenster für Gasschutzmasken mit fest eingepreßten Fensterscheiben bekannt. Bei diesen besteht jedoch der Fensterrahmen meistens aus mehreren Teilen, oder die Fensterscheibe wird durch Umlegen eines Randes am Fensterrahmen festgehalten. Diese Befestigungsarten ergeben einen verhältnismäßig breiten Fensterrahmen. Außerdem befindet sich die Fensterscheibe am Außenrand des Fensters.There are already windows for gas masks with firmly pressed in Window panes known. With these, however, the window frame consists mostly of several parts, or the window pane is opened by folding an edge on the window frame held. These types of attachment result in a relatively wide window frame. In addition, the window pane is located on the outer edge of the window.
Ferner ist es schon bei Atemschutzfiltern bekannt, die die einzelnen Filterschichten trennenden und festhaltenden Siebe durch in den Mantel des Filtergehäuses eingerollte Sicken festzulegen. Man hat aber bisher noch nicht erkannt, daß es bei einem wesentlich anders ausgebildeten Gegenstand, nämlich dem Fenster einer Gasschutzmaske, vorteilhaft ist, die Fensterscheibe auf diese Weise im Fensterrahmen zu befestigen. Hierdurch wird `eine wesentliche Vereinfachung der Massenherstellung solcher Fenster für Gasschutzmasken erreicht.Furthermore, it is already known for respiratory protection filters that the individual Filters separating and holding the filter layers through into the jacket of the filter housing define rolled beads. But it has not yet been recognized that a significantly different object, namely the window of a gas mask, it is advantageous to attach the window pane in this way in the window frame. This significantly simplifies the mass production of such windows for gas masks.
In der Zeichnung sind zwei Ausführungsbeispiele im Schnitt dargestellt.Two exemplary embodiments are shown in section in the drawing.
Abb. i zeigt den mit einem angekrempelten Flansch b versehenen, aus einem Stück hergestellten Fensterrahmen a, gegen den sich die Fensterscheibe h nach dem Einsetzen in den Rahmen a unter Vermittlung des Dichtringes in legt.Fig. I shows the one provided with a rolled-up flange b a piece of manufactured window frame a, against which the window pane h is after the insertion into the frame a with the mediation of the sealing ring in sets.
Abb.2 zeigt den gasdichten Einbau der Fensterscheibe in den Fensterrahmen. Zu diesem Zwecke ist in den in den Maskenstoftk eingebundenen Mantel des Fensterrahmens a eine die Scheibe lt gegen den Dichtring in pressende Sicke g eingerollt. Der Fensterrahmen a trägt noch einen sich nach dem Maskeninnern zu kegelförmig erweiter ndenRand c, der zum Einsetzen des die Klarscheibe d haltenden Sprengringes e dient.Fig. 2 shows the gas-tight installation of the window pane in the window frame. For this purpose, a bead g that presses the pane lt against the sealing ring is rolled into the jacket of the window frame a that is integrated into the masking material. The window frame a also has an edge c which widens in a conical shape towards the inside of the mask and which serves to insert the snap ring e holding the clear pane d.
Zwischen der Fensterscheibe lt und der eingerollten Sicke g kann, wie Abb. 3 zeigt, -ein Schutzring i aus Metall oder Kunststoff liegen.Between the window pane lt and the rolled-up bead g, As Fig. 3 shows, -a protective ring i made of metal or plastic.
