Die Auflagefläche für den Deckel 10 und die Stoßflächen der beiden Teile des Spiegelschachtes 5 liegen in einer Ebene. Auf diese Fläche wird nun eine aus Gummi oder gummiähnlichem Material hergestellte Membrane 12 gelegt, in die eint· die Kammer 11 ausfüllende Falte 13 eingeformt ist. Nunmehr werden sowohl der Deckel 10 als auch der obere Teil 5 a des Spiegelschachtes 5 aufgesetzt uiid durch Schrauben mit dem unteren Teil bzw. dem Drehkranz 3 fest verbunden. Diese Falte 13 stellt nichts anderes dar als eine Materialanhäufung der Membrane 12, die es ermöglicht, die Kippbewegungen des Spiegelschachtes 5 mitzumachen, ohne daß schädliche Spannungen in der Membrane 12 auftreten und eine Beeinträchtigung der Dichtungsfunktion zu befürchten ist.The support surface for the cover 10 and the abutment surfaces the two parts of the mirror shaft 5 lie in one plane. On this surface there is now an off Membrane 12 made of rubber or rubber-like material is placed into which the chamber 11 fills Fold 13 is formed. Now both the cover 10 and the upper part 5 a of the Mirror shaft 5 put on uiid by screws with the lower part or the turntable 3 connected. This fold 13 represents nothing other than an accumulation of material of the membrane 12, which it allows to participate in the tilting movements of the mirror shaft 5 without damaging stresses occur in the membrane 12 and an impairment of the sealing function is to be feared.

Zwecks vollständiger Aufzählung der bekannten Einzelteile des Winkelspiegellagers sei noch erwähnt, daß unterhalb des Spiegelschachtes 5 an diesem der Winkelspiegelhalter 14 befestigt ist, an den ein Klemmbügel 15 angelenkt ist. Letzterer trägt zu beiden Seiten des Winkelspiegels 16 je eine Rolle 17, die nach dem Einsetzen des Winkelspiegel 16 in den Spiegelschacht 5 durch Hochschwenken des Klemmbügeis 15 den mit einer rahmenförmigen Dichtung 21 ausgelegten Flansch 18 des Winkelspiegels U gegen die Unterkante des Spiegelschachtes 5 preßt. Seitlich am Winkelspiegelhalter 14 sitzei, zwei ausklappbare Handgriffe 19, mit denen der Winkelspiegel 16 in dieFor the purpose of a complete listing of the known individual parts of the angle mirror bearing, it should also be mentioned that the angle mirror holder 14 is attached below the mirror shaft 5, to which a clamping bracket 15 is articulated. The latter carries a roller 17 on both sides of the corner mirror 16 which, after the corner mirror 16 has been inserted into the mirror shaft 5, presses the flange 18 of the corner mirror U, designed with a frame-shaped seal 21, against the lower edge of the mirror shaft 5 by pivoting the clamping bracket 15 upwards. Laterally on the corner mirror holder 14 sitzei, two fold-out handles 19 with which the corner mirror 16 in the

In Verbindung mit den anderen Dichtungen 21, die nur zwischen feststehenden oder solchen Teilen mit gleichförmigen Bewegungen eingesetzt sind, ist die Membrandichtung in hervorragender Weise geeignet, das Eindringen von Wasser, wie auch von Gasen und Kampfstoffen durch das Winkelspiegel-Jager in das Innere des Fahrzeugs zu verhindern.In connection with the other seals 21, which are only between fixed or such parts are used with uniform movements, the membrane seal is ideally suited to the penetration of water as well as gases and warfare agents through the corner mirror hunter to prevent getting into the interior of the vehicle.

Claims

during underwater travel due to a meter-high patent claim: If the water column is loaded, the previous lip seal between the slewing ring and the mirror shaft fails.
