Description
;'-x l e. Scheinwerfer, insbesondere für Fahrräder, Motorräder u. däl. Die Verbindung des Reflektors mit dem die Glasscheibe aufnehmenden Abschlußring des Scheinwerfers wird bisher in der Weise bewirkt, daß der Reflektor nach Zwischenschaltung der Glasscheibe mit dem Abschlußring verschraubt wird oder die Teile durch eignen Sprengring verbunden werden. Es ist auch vorgeschlagen worden, den abgebogenen Rand des Reflektors aufzuschlitzen und zu einem Gewindegang zu schränken. Diese Ausbildung hat sich jedoch nicht bewährt, da der Gewinderand des Reflektors sich nur teilweise gegen die Glasscheibe legt, so daß eine einwandfreie Verbindung der Teile nicht erhalten werden kann. Der Rand des R--flektors wird nun, tun diesen übelstand zu beheben, gemäß der Erfindung so abgebogen, daß vor dem durch Schränken erhaltenen Gewindegang ein vollkommen ebener, sich dicht auf die Glasscheibe legender Abschlußrand gebildet wird. Durch schwach konische Neigung der Ebene des Gewindeganges nach hinten kann weiter ein elastisches Auflegen des Dichtungsrandes des Reflektors auf die Glasscheibe erreicht werden, wobei sich gleichzeitig der Vorteil ergibt, daß durch die federnde Durchbiegung beim Anziehen der Teile diese gegen Lösen gesichert sind, da der Gewindegang beim festen Anziehen sich in dem Muttergewinde etwas sperrt. Das zum Einschrauben des Reflektors dienende Gewinde des Abschlußringes kann gleichzeitig zum Verschrauben mit dem Scheinwerfermantel dienen, so daß beim Verschrauben der Teile mit dem Mantel der Gevnndegang des Reflektors vermöge seiner elastischen Eigenschaft gleichzeitig als Sicherung der Teile gegen Lösen dient.; '- x l e. Headlights, especially for bicycles, motorcycles and the like. däl. The connection of the reflector with the closing ring receiving the glass pane of the headlamp has so far been effected in such a way that the reflector after interposition the glass pane is screwed to the locking ring or the parts are suitable Snap ring are connected. It has also been suggested to use the bent edge slit open the reflector and turn it into a thread. This training However, it has not proven its worth, as the thread edge of the reflector is only partially against the glass, so that a proper connection of the parts does not can be obtained. The edge of the R-reflector will now do this evil fix, bent according to the invention so that before the obtained by cabinets The thread turn is a completely flat end rim that lies tightly on the pane of glass is formed. By slightly conical inclination of the plane of the thread to the rear can further an elastic placement of the sealing edge of the reflector on the Glass pane can be achieved, at the same time there is the advantage that by the resilient deflection when tightening the parts they are secured against loosening, because the thread turns a little blocked in the nut thread when tightened. The thread of the closing ring used to screw in the reflector can be used at the same time serve to screw with the headlight casing, so that when screwing the Share with the jacket the progression of the reflector by virtue of its elastic property at the same time serves to secure the parts against loosening.
Auf der Zeichnung ist eine Ausführungsform des Gegenstandes der Erfindung dargestellt.In the drawing is an embodiment of the subject matter of the invention shown.
Die Glasscheibe a ist in dem Abschlußring b durch Einschrauben des Reflektors c festgeklemmt. Der Rand d des Reflektors ist so abgebogen, daß er den auf der Glasscheibe aufliegenden, vollkommen ebenen Dichtungsrand c bildet. Durch Aufschlitzen des Randes d ist dieser durch Schränkung zu einem Gewindegang ausgebildet. Das zum Einschrauben des Reflektors im Abschlußring vorgesehene Gewinde dient gleichzeitig zum Verschrauben mit dem Scheinwerfermantel f.The glass pane a is in the end ring b by screwing the Clamped reflector c. The edge d of the reflector is bent so that he forms completely flat sealing edge c resting on the glass. By Slitting of the edge d, this is formed by twisting to form a thread. The thread provided for screwing in the reflector in the end ring serves at the same time for screwing to the headlight casing f.
