Description

  • Rückseitige Abdichtung von Rückstrahlern aus Plastic.
  • Rückstrahler müssen nach bestehenden Vorschriften rückseitig luftdicht abgeschlossen oder verspiegelt sein.
  • Die Verspiegelung ist als manueller Arbeitsprozess kostspielig weil zusätzlich die Spiegelschicht noch mit einem Schutzlack versehen werden muss.
  • Die Erfindung schlägt deshalb bei Rückstrahlern aus plastischen
    Kunststoffen vor, den Fassungsrand des Rückstrahlern so auszu-
    bilden, dass dieser über die rückstrahlenden frismen hinaus-
    steht, sodass eine Plasticfolie maschinell im Sochfrequenzver-
    fahren aufgeschweisst werden kann.
  • Um bei den unterschiedlichen Materialstärken zwischen Rückstrahler und Folie ein besseres Verschweissen zu ermöglichen, kann der Fassungsrand des Rückstrahlers eine hochstehende umlaufende Schweisskante erhalten.
  • Als weitere Lösung der Aufgabe schlägt die Erfindung vor, dass der Fassungsrand des Rückstrahlers nach innen abgestuft ist.
  • In die Abstufung wird ein entsprechend ausgeschnittenes Stück Flasticfolie eingelegt und der aussen überstehende Rand die Folie überlappend verschweisst.
  • Der aussen überstehende Rand kann hierbei vorteilhaft so ausgebildet sein, dass er noch eine hochstehende nach aussen schräg ablaufende Schweißkante hat.
  • In den Schnittzeichnungen wird das vorstehend Beschriebene dargestellt.
  • Fig. 1 zeigt einen Rückstrahler mit hochstehendem Fassungsrand 1 auf dem die Folie 2 verschweist ist.
  • Fig. 2 zeigt einen Rückstrahler mit hochstehendem Fassungsrand 3 der zusätzlich mit einer umlaufenden hochstehenden Schweisskante 4 versehen ist, mit der die Folie 5 verschweist wird.
  • Fig. 3 zeigt einen Rückstrahler mit hochstehendem lassungsrand 6, der nach innen eine umlaufende Abstufung 7 hat, in die der Folienausschnitt 8 eingelegt und mit dem Aussenrand 6 überlappend verschweiß wird.
  • Fig. 4 zeigt einen Rückstrahler mit hochstehendem Fassungsrand 9, der nach innen eine umlaufende Abstufung 10 hat, in die der Folie :
    ausschnitt 11 eingelegt und mit dem Aussenrand 9, der eine nach
    aussen schräg ablaufende Schweisskante 12 hat, überlappend ver-
    schweißwird.
