Description
Bei den bisher bekannt gewordenen Bildwerfern mit zwei durch Zahnräder bewegten endlosen Ketten werden sämtliche an den Ketten hängenden Bilderrahmen in einem Magazin o. dgl. hintereinander abgesetzt, bis sie zur Vorführung an die Reihe kommen. Bei dieser Anordnung traten durch das Anstauen der Bilderrahmen im Magazin leicht Betriebsstörungen ein. Dieser Mißstand soll durch ίο die Erfindung dadurch gehoben werden, daß die Bilderrahmen an verschieden langen Achsen hängen, die durch die Glieder der beiden endlosen Ketten hindurchgehen. Diese wirken mit Auflagern, die verschiedene den Achsenlängen angepaßte Abstände haben, zusammen, so daß die Bilderrahmen im unteren Teile des Bildwerfers stufenweise abgesetzt werden.In the previously known image projectors with two moving gears endless chains, all picture frames hanging on the chains are placed one behind the other in a magazine or the like until it is their turn to perform. With this arrangement stepped through the damming the picture frame in the magazine easily malfunctions. This grievance should go through ίο the invention can be lifted by the fact that the picture frames at different lengths Hang axes that go through the links of the two endless chains. These work with supports that are different the axis lengths have adapted distances together, so that the picture frame in the lower Parts of the projector are gradually removed.
Der Gegenstand der Erfindung ist auf der Zeichnung in einer beispielsweisen Ausführungsform dargestellt.The object of the invention is shown in the drawing in an exemplary embodiment shown.
Abb. ι ist eine Seitenansicht des Bildwerfers mit zwei Rahmenstufen;Fig. Ι is a side view of the projector with two frame stages;
Abb. 2 ist eine Vorderansicht des Gegenstandes nach Abb. 1 undFig. 2 is a front view of the article of Figs. 1 and 4
Abb. 3 zeigt die Anordnung der Achsen und Auflager bei vier Rahmenstufen.Fig. 3 shows the arrangement of the axes and supports for four frame levels.
Der Apparat besteht aus einer leichtenThe apparatus consists of a lightweight
Eisenkonstruktion. Der Antrieb wird wie üblich mit Hilfe eines Schnecken- und Zahnradgetriebes
bewirkt, welches mit einem Elektromotor gekuppelt sein kann.
α ist ein Lichtkasten, in dem sich die elektrischen
Lampen b befinden, die das in dem Bilderrahmen c eingesetzte Bild gleichmäßig
beleuchten.Iron construction. The drive is effected as usual with the help of a worm and gear drive, which can be coupled to an electric motor.
α is a light box in which the electric lamps b are located, which uniformly illuminate the picture set in the picture frame c.
Über die Kettenräder d kufen zwei endlose Gelenkketten e, die von den Achsen /, welche die Bilderrahmen c tragen, durchsetzt sind. Wenn der Apparat im Betrieb ist, werden die Bilderrahmen c auf ihren den Längen der Achsen f entsprechenden schrägen Auflagern g stufenweise abgesetzt. Hierbei kann die unterste Stufe frei hängen. Die Bilderrahmen c gleiten auf den schrägen Auf-Two endless articulated chains e run over the chain wheels d, through which the axes /, which carry the picture frames c , pass through. When the apparatus is in operation, the picture frames c are gradually set down on their inclined supports g corresponding to the lengths of the axes f. The lowest step can hang freely. The picture frames c slide on the sloping
