Dieser Innenring h;,l etwa die Bleue de- Gehäuseraniies und eine innere Schulter 2i. die kongru-.■n; /um Rande 4' des Spiegelglases 4 verläuft und dieses im Gehäuse ohne Zwängung /entrien.

Die etwa senkrecht /um Gehäuscboden siehende innere Ringfläehe ist mit mehrerer, sägezahnlörniigen ^!<mgnuien 22 versehen. Die Schulter 21 steigt in den !'.ereich der linieren, tiefer hegenden Ringnuten auf uml bildet eine konische Außenfläche 21.The inner ring surface, which is approximately perpendicular / around the bottom of the housing, has several sawtooth-like shapes ^! <mgnuien 22 provided. The shoulder 21 rises into the area of the lined, deeper-lying ring grooves around it and forms a conical outer surface 21.

Der Außenring3 hat einen etwa pilzförmigen Qi'erschniu (Fig. 3). Der -Stiel··. 31 weist an seiner Außenfläche sägezahnförmige Rinniuiien 32 auf. die zu denen des Innenringes passen, und hat eine konische Innenfläche 31'. die zur konischen Außenfläche der Innenringschulter paßt. Der ;Kopf:- 3' — oder Innenflansch des Außenringes — ist etwas nach unten gezogen.The outer ring3 is approximately mushroom-shaped Qi'erschniu (Fig. 3). The stem··. 31 points to his Sawtooth-shaped grooves 32 on the outer surface. the to match those of the inner ring, and has a conical Inner surface 31 '. which matches the conical outer surface of the inner ring shoulder. The; head: - 3 '- or Inner flange of the outer ring - is pulled down a little.

Beim Zusammenbau werden Innenring 2 und Spiegelglas 4 in die Gehäuseschale 1 eingelegt. Das Spiegelglas wird von der ringförmigen Schulter 21 lose zentriert und ruht mit seinem Belag? auf der Wölbung des Innen; ingflan-chcs 2'.During assembly, the inner ring 2 and mirror glass 4 are inserted into the housing shell 1. The mirror glass is loosely centered by the annular shoulder 21 and rests with its coating? on the vault of the inside; ingflan-chcs 2 '.

Gegen Fnde der Finpreßbewegung legt sich der Innenflansch 3' des Außenringes längs des Rande-4 auf die Oberfläche des Spiegelglases und iliückt die ses leicht und elastisch in das Gehäuse hinein und ge gei; ο:·.- stützende Wölbung Z' des Ivuiennnges. üabe; werden die Randkanten des ^"picuclgiascs niclv. Ικ·- liihrt. so daß ein Absplittern ii:r empfindlichen Kanten nicht auftreten kann. Auch cmc Facettierung des in Glasrandes ist nicht erforderlich, wie sich aus Fig. i deutlich ergibt. Die Wölbung im Flansch 2' des IniK.,ringes kann entfedern, so daß Toleranzen, insbesondere in der Glasdicke, ausgeglichen werden können, ohne daß Zwi'mguiigen auftreten können oiler der Spiegelbelag5 verletzt werden könnte.Towards the end of the fin press movement, the inner flange lies down 3 'of the outer ring along the edge-4 onto the surface of the mirror glass and press the This is easy and elastic in the housing and ge gei; ο: · .- supporting arch Z 'of the Ivuiennnges. üabe; the marginal edges of the ^ "picuclgiascs niclv. Ικ · - leads. so that a chipping ii: r sensitive edges cannot occur. Also cmc faceting of the in the glass edge is not necessary, as can be seen from Fig. i clearly shows. The bulge in the flange 2 'of the IniK., Ring can spring down so that tolerances, especially in the glass thickness, can be compensated, without inconsistencies being able to occur oiler the mirror covering5 could be damaged.

In bekannter Weise liegen die ranilnahen Zonen an Ober- und Unterseite des Spiegelglases, ir, denen die von Innen- und Außenring übertragenen Druckkräfte angreifen, einander gegenüber (Fig. I). bei runden Spiegeln also auf gleichen Radien, damit im Glas keine Biegespannungen auftreten können.The zones close to the ranil are located in a known manner on the top and bottom of the mirror glass, ir, where the pressure forces transmitted by the inner and outer ring attack, facing each other (Fig. I). with round mirrors on the same radii, so im No bending stresses can occur in the glass.
