There are devices for projecting light images are known that on a advertising pillar above the shaft.

Gegenstand der Erfindung ist eine Einrichtung zur Projektion von Lichtbildern im Freien unter Ausschaltung der auf die Bildstreifen ungünstigen Einflüsse von Temperaturschwankungen und Feuchtigkeit.The invention relates to a device for projecting light images outdoors with the elimination of the unfavorable influences of Temperature fluctuations and humidity.

Die Zeichnung zeigt in schematischer Darstellung ein Ausführungsbeispiel der Erfindung, ohne andere Ausführungen im Rahmen des Erfindungsgedankens auszuschließen.The drawing shows a schematic representation of an embodiment of the invention without excluding other designs within the scope of the inventive concept.

Abb. i zeigt die Einrichtung im Längsschnitt.Fig. I shows the device in longitudinal section.

a ist der Projektionsapparat, der das Bild durch eine am Auffangebecken f für Schwitzwasser gehende Öffnung gegen einen schräg stehenden Spiegel b im oberen Teil der Säule k wirft. Von dem Spiegel b wird das Bild wieder gegen den Projektionsschirm c geworfen, wodurch es von außen sichtbar wird. Regenwasser und Schwitzwasser sammelt sich im Becken f und in der Grube g. Die unteren und oberen Teile der Einrichtung sind durch die Bedienungsklappe e und d zugänglich. Die Bedachung der Säule k ist bei L aufklappbar. Der Schrank lt für die Bedienung des Apparates befindet sich im oberen Teil der Säule k.a is the projection apparatus that throws the image through an opening in the collecting basin f for condensation water against an inclined mirror b in the upper part of the column k. The image is thrown from the mirror b again against the projection screen c, whereby it is visible from the outside. Rainwater and condensation water collects in the basin f and in the pit g. The lower and upper parts of the device are accessible through control flaps e and d . The roofing of pillar k can be opened at L. The cabinet lt for the operation of the apparatus is in the upper part of the column k.

Abb. a zeigt den Grumdriß im Schnitt C-D der Abb. i, während Abb. 3 den Schnitt der Abb. i veranschaulicht.Fig. A shows the outline in section C-D of Fig. I, while Fig. Figure 3 illustrates the section of Figure i.
