Description

Die Erfindung bezieht.. sich auf einen Scheinwerfet mit einem lösbaren Deckelring, der eine Abschlußscheibe sowie einen Hohlspiegel trägt und - an einer die öffnung des Scheinwerfergehäuses umgebenden Ringschulter anliegend - oben durch ein hakenartiges Halteglied und unten durch eine Schraube befestigt ist, deren Achse etwa parallel zu der schräg nach unten gerichteten Randzone des Hohlspiegels verläuft. Der Erfindung liegt die Aufgabe zugrunde, bei einem Scheinwerfer der genannten Art einen möglichst schmalen Deckelring .zu verwenden und damit in einem Gehäuse von gegehener Größe einen möglichst großen Hohlspiegel sowie eine Streuscheibe von erheblichem Lichtaustrittsqwerschnitt unterbringen zu können und -gleichzeitig die Anbringung besonderer Befestigungsmittel zum Einsetzen der Befestigungsschraube zu ersparen.The invention relates to a headlight with a detachable Cover ring, which carries a cover plate and a concave mirror and - on one the ring shoulder surrounding the opening of the headlight housing - through at the top a hook-like retaining member and is fastened below by a screw, the axis of which runs approximately parallel to the obliquely downward edge zone of the concave mirror. The invention is based on the object, in a headlight of the type mentioned to use a cover ring that is as narrow as possible and thus in a housing of The largest possible concave mirror as well as a diffusing screen of considerable size To be able to accommodate light exit cross-section and at the same time the attachment to save special fasteners for inserting the fastening screw.

Dies wird erfindungsgemäß dadurch .erreicht, daß die Befestigungsschraube des Deckelringes in eine die Gehäuse-Ringschulter unterbrechende,. etwa senkrecht zur f Schraubenachse gerichtete Eindrükkung der Ringschulter eingesetzt ist. Infolge dieser senkrechten Eindrückung erstreckt sich der Schaft der Befestigungsschraube schräg zur Scheinwerferachse und etwa parallel zum unteren Teil des Hohlspiegels. Die Befestigungsschraube beansprucht also :einen nur geringen Raum und kann überdies noch unauffällig untergebracht werden, da sich die Eindrückung am einer Stelle des Gehäuses befindet, die vom Deckelring abgedeckt ist.According to the invention, this is achieved in that the fastening screw of the cover ring in a housing ring shoulder interrupting. roughly perpendicular The indentation of the ring shoulder directed towards the screw axis is inserted. As a result This vertical indentation extends the shaft of the fastening screw obliquely to the headlight axis and approximately parallel to the lower part of the concave mirror. The fastening screw therefore takes up only a small amount of space and, moreover, can can still be accommodated inconspicuously, since the indentation is at one point of the Housing is located, which is covered by the cover ring.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigt Abb. i einen Scheinwerfer teilweise im Längsschnitt und Abb. 2 eine Draufsicht auf den untemen Teil des Gehäuserandes bei abgenommenem Deckelring. Ein Scheinwerfergehäuse i hat vorn zur Versteifung einen Rand 2 nach Art eines -eingezogenen Flangchringes, :an .dem sich eine Ringschulterr 3 befindet. Ein Deckelring 4, der- einen Hohlspiegel 5 und eine Absichlußscheibe 6 trägt, ist mit seinem umgebördelten hinteren Rand 7 auf der Ringschulter 3 ,gelagert. Ein oben an der Innenseite des Deckelringes 4 ,angebrachter Lappen $ ist m eine schmale Aussparung 9 in der Ringschulter 3 @eingehängt. Unten am Deckelring 4 befindet sich ein Loch io, hinter .dem an der Innenseite des Deckeliinges 4 . ein Blechwinkel .i i befestigt ist, der als Widerlager für den Köpf .einer Befestigungsschraube 12 dient. Der Gehäuserand 2 ist tunten flachgedrückt, so daß ein schräg nach innen, etwa senkreehf gegen den unteren Teil des Hohlspiegels 5 gerichteter Lappen 13 entsteht, an dessen Rückseite ein mit einer Gewindebohrung für die Schraube 12 versehenes Plättchen 14 angeschweißt ist.An exemplary embodiment of the subject matter of the invention is shown in the drawing. Fig. 1 shows a headlight partially in longitudinal section and Fig. 2 shows a plan view of the lower part of the housing edge with the cover ring removed. A headlight housing i has at the front for stiffening an edge 2 in the manner of a - drawn-in flange ring,: on which an annular shoulder 3 is located. A cover ring 4, which carries a concave mirror 5 and a sealing disk 6, is supported with its flanged rear edge 7 on the ring shoulder 3. A tab $ attached to the top of the inside of the cover ring 4 is hung in a narrow recess 9 in the ring shoulder 3 @. At the bottom of the cover ring 4 there is a hole io, behind .dem on the inside of the cover ring 4. a sheet metal angle .ii is attached, which serves as an abutment for the head .einer fastening screw 12. The edge of the housing 2 is flattened so that an obliquely inward, approximately perpendicularly directed against the lower part of the concave mirror 5 flap 13 is formed, on the back of which a plate 14 provided with a threaded hole for the screw 12 is welded.

Wie aus der Zeichnung ersichtlich ist, liegen die Verschlußteile i i und 14 im Innern- des ScheinwerfeTs, so daß dieser eine glatte Außenform aufweist. Gleichwohl kann der Deckelring zum Auswechseln der in den Hohlspiegel in üblichen- Weise von hinten eingesetzten Glühlampe leicht abgenommen ün:d.:damch-wieder befestigt werden. Infolge der schrägen Eindrückung 13 ist der Schaft der Schraube 12 etwa parallel zum unteren Teil des Hohlspiegels gerichtet. Die Verschraubung erfordert also nur -wenig Platz und kann daher auch auf einem schmalen Deckelring an einem Scheinwerfer untergebracht werden, dessen Gehäuseraum weitgehend für die Unterbringung eines vergleichsweise großen Hohlspiegels anisgenutzt ist.As can be seen from the drawing, the closure parts are i i and 14 inside the headlight, so that it has a smooth outer shape. At the same time, the cover ring can be used to replace the The incandescent lamp inserted from the rear was slightly removed and reattached will. As a result of the oblique indentation 13, the shaft of the screw 12 is approximately directed parallel to the lower part of the concave mirror. The screw connection requires so only little space and can therefore also on a narrow cover ring on one Headlights are housed, the housing space largely for housing a comparatively large concave mirror anise is used.
