Description

Den Gegenstand der Erfindung bildet ein auswechselbares Bildfenster für kinematographische Wiedergafoeappairate, die sowohl für Schwarzweißbilder als auch für Farbenbilder benutzt wenden sollen. Das Wesen der Erfindung besteht darin, daß das Bildfenster als Ganzes durch Bajonettverschluß und Federverriegelung in seiner Lage gesichert ist. Auf 'der Zeichnung· sind zwei Ausführungsformen der Erfindung zur Darstellung gebracht, und zwar zeigen:
Abb. ι einen Längsschnitt, Abb. 2 einen Schnitt 2-2 ider Abib. 1, Abb. 3 einen Querschnitt der ersten Ausführungsform,
The subject of the invention is an interchangeable picture window for cinematographic display devices which are to be used both for black and white pictures and for color pictures. The essence of the invention is that the picture window is secured in its position as a whole by a bayonet lock and spring lock. On the drawing two embodiments of the invention are shown, namely show:
Fig. Ι a longitudinal section, Fig. 2 a section 2-2 ider Abib. 1, Fig. 3 shows a cross section of the first embodiment,

Abb. 4, 5, 6 die zweite Ausführungfsform. Es bezeichnet α das Gehäuse, das mit Lageransätzen a1 iziir Aufnahme einer rechteckigen Stange b versehen ist, die etwa durch Schrauben c befestigt ist. Das Bildfenster d, das mit einem abklappbaren Teil ausgerüstet ist, besitzt eine Nabe d1 mit Bohrung d2. Diese Nabe ist in der Gebrauchsstellung von ziwei Backen e umfaßt und gegen Drehung gesichert. Die Flächen e1 der federnden Backen kommen nämlich gegen entsprechend gestaltete Flächen des Bildfensters zu liegen. Ferner stützen sich die Backen e mit ihren Flächen e1 .gegen den Gehäuseteil a. Die Backen e stehen unter Wirkung von Federn /. Soll 'das .Fenster d ausgewechselt werden, so wenden die Backen e entgegen der Wirkung der Federn / ,zusammengedrückt, so daß sie in dem Ausschnitt xx des Fensters zu Hegen kommen (punktierte Lage, Abib. 2). Infolgedessen können die Flächen e1 von den Flächen d* abgleiten, und das Bildfenster kann in die punktiert angegebene Lage gemäß Abb. 3 gedreht Averden. In dieser Stellung liegt der Schlitz dß der Nabe d1 vor den schmalen Kanten des Flachstabes b. Infolgedessen kann das Bildfenster abgezogen und ausgewechselt wenden.Fig. 4, 5, 6 the second embodiment. It denotes α the housing, which is provided with bearing lugs a 1 iziir receiving a rectangular rod b , which is fastened for example by screws c. The image window d, which is equipped with a hinged part, has a hub d 1 with a bore d 2 . In the position of use, this hub is surrounded by two jaws e and secured against rotation. The surfaces e 1 of the resilient jaws come to lie against correspondingly designed surfaces of the picture window. Furthermore, the jaws e are supported with their surfaces e 1. Against the housing part a. The jaws e are under the action of springs /. If the window d is to be exchanged, the jaws e turn against the action of the springs /, pressed together, so that they come to rest in the cutout x x of the window (dotted position, Fig. 2). As a result, the surfaces e 1 can slide off the surfaces d * , and the image window can be rotated into the position indicated by dotted lines according to FIG. 3. In this position, the slot d ß of the hub d 1 lies in front of the narrow edges of the flat bar b. As a result, the image window can be peeled off and replaced.

Gemäß Abb. 4 bis 6 ist die Einrichtung so getroffen, daß das Bildfenster d mit einer schwalbenschwanzförmigenFührungg· in einer entsprechend gestalteten Aussparung des Gehäuses α einschiebbar ist. Die Stellung des Fensters d wird durch einen Federbolzen h gesichert, der in die Aussparung· % des Gehäuses einschnappen kann.According to Figs. 4 to 6, the device is designed in such a way that the picture window d with a dovetail-shaped guide g can be pushed into a correspondingly shaped recess in the housing α. The position of the window is secured by a spring bolt h d, the · in the recess can snap% of the housing.
