KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Einrichtung für Projektionsdarstellungen u. dgl., bei der die Zuschauer das auf einen verborgen liegenden Schirm geworfene Projektionsbild in einem geneigten Spiegel bei normaler Beleuchtung betrachten, und die sich in ihrer Neuheit dadurch kennzeichnet, daß der Spiegel gleichzeitig dazu benutzt wird, die von dem im Zuschauerraum aufgestellten Projektionsapparat ausgehenden Bildstrahlen auf den Schirm zu reflektieren.The present invention relates to a device for projection displays and the like. in which the audience sees the projection image projected onto a hidden screen look in an inclined mirror in normal lighting, and look at yourself in their Novelty is characterized by the fact that the mirror is used at the same time as that of the In the auditorium set up projection apparatus outgoing image rays on the Reflecting screen.
Auf der Zeichnung ist eine Ausführungsform der Projektionseinrichtung schematisch dargestellt.An embodiment of the projection device is shown schematically in the drawing shown.
Die Vorrichtung besteht aus einem wagerecht liegenden, lichtundurchlässigen Schirm 1, welcher aus einer matt gemachten und mit einem Spiegelbelage versehenen Glasscheibe bestehen kann.The device consists of a horizontally lying, opaque screen 1, which is made of a matt-finished glass pane with a mirror coating can exist.
Auch kann man hierzu eine Glasscheibe benutzen, deren dem Spiegelbelage gegenüberliegende Fläche matt gemacht wird.A glass pane can also be used for this purpose, the one opposite the mirror covering Surface is made matt.
Die Kante des Schirmes, welche dem Publikum am nächsten liegt, wird durch eine senkrechte Wand 2, also z. B. dem oberen Teil des Theatervorhanges (Harlekinmantel) verborgen.The edge of the screen that is closest to the audience is covered by a vertical wall 2, so z. B. the upper part of the theater curtain (harlequin coat) hidden.
Unterhalb des Schirmes 1 liegt ein unter 450 geneigter Spiegel, dessen unterste Kante dem Beschauer 4 am nächsten liegt.Below the screen 1 is a at 45 0 inclined mirror whose lowermost edge of the observer 4 is closest.
Die Projektionslaterne 5 befindet sich wie üblich im hinteren Teile des Saales.The projection lantern 5 is, as usual, in the rear part of the hall.
denthe
Das Lichtbild wird auf einen unter 45c
neigten Spiegel projiziert, welcher es auf
Schirm 1 zurückwirft.The photo will be on a below 45 c
inclined mirror projecting what it was on
Reflects screen 1.
Das darauf erzeugte Bild wird wieder im Spiegel wiedergespiegelt und somit dem Beschauer kenntlich gemacht. Um den Schirm dem Publikum unsichtbar zu machen, kann sich derselbe in einer gewissen Entfernung vom Spiegel befinden.The image created on it is reflected again in the mirror and thus to the viewer marked. In order to make the screen invisible to the audience, the screen can be at a certain distance from the Mirrors are located.
Spiegel und Schirm bilden stets einen Winkel von 45 °, gleichviel ob der Spiegel mit Bezug auf den wagerechten Boden eine andere Neigung einnimmt.Mirror and screen always form an angle of 45 °, regardless of whether the mirror is with it Has a different inclination with respect to the horizontal floor.
Die Projektionslaterne wird so angeordnet, daß die Lichtstrahlen unter 45 ° auf den Spiegel fallen.The projection lantern is arranged in such a way that the light rays hit the mirror at an angle of 45 ° fall.
Die oben beschriebene Anordnung des Spiegels mit Bezug auf den Schirm kann natürlich auch eine umgekehrte sein.The above-described arrangement of the mirror with respect to the screen can of course also be a reverse.
