Description
Drehbarer Sucher für photographische Apparate Den Gegenstand der Erfindung bildet ein drehbarer Sucher für photographische Apparate, welcher in bekannter Weise am Objektivbrett in verschiedene Neigungen eingestellt werden kann. Die Neuerung besteht darin, daß nunmehr die Libelle .an der Vorderseite des Objektivbrettes ausliegt und ihr Halter als Anschlag für den Sucher in seinen beiden Stellungen dient.Rotatable viewfinder for photographic apparatus The object of the invention forms a rotatable viewfinder for photographic apparatus, which in a known manner can be adjusted to various inclinations on the lens board. The innovation consists in the fact that now the dragonfly is displayed on the front of the lens board and its holder serves as a stop for the viewfinder in both of its positions.
Auf der Zeichnung ist ein Ausführungsbeispiel in fünf Abbildungen dargestellt. Es zeigt Abb. r eine Vorderansicht, Abb. 2 eine Seitenansicht, Abb.3 den Grundriß der Abb. I, Abb. ¢ eine Vorderansicht des Halters, Abb. 5 einen Querschnitt nach A-B. Gemäß der Erfindung ist der Halter für die Wasserwaage (Libelle) als Anschlag für den Sucher verwendet. Zu diesem Zweck besitzt das Objektivbrett a einen kreisförmigen Schlitz b, durch welchen der Tragarm c für die Libelle d hindurchgreift, so daß diese unmittelbar vor und unterhalb des Suchers ausliegt, also viel leichter übersehen werden kann, als wenn die Libelle, wie bisher, an einer anderen Stelle des Suchers angebracht wäre. Der Tragbügel. für den Sucher weist zu .diesem Zwecke den Tragarm c, in den Tragarmen e des Suchers/ entgegengesetzter Richtung umerlaufend, auf, und es ist der Tragarm. c mit einer entsprechenden Durchbohrung versehen, um an dieser Stelle die Libelle fest, machen zu können. Dreht man nun den Sucher von der Aufrechtstellung in die Wagerechtstellung, so dient der Tragarm c an den beeiden Enden des kreisförmigen Schlitzes b als Anschlag für diese Bewegung.In the drawing, an exemplary embodiment is shown in five figures. It shows Fig. R a front view, Fig. 2 a side view, Fig. 3 the plan of Fig. I, Fig. ¢ a front view of the holder, Fig. 5 a cross section to AB. According to the invention, the holder for the spirit level (dragonfly) is used as a stop for the viewfinder. For this purpose, the lens board a has a circular slot b through which the support arm c for the dragonfly d extends, so that it is displayed directly in front of and below the viewfinder, so it can be overlooked much more easily than when the dragonfly, as before, is on at another point in the viewfinder. The handle. for the viewfinder, this purpose has the support arm c, revolving in the support arms e of the viewfinder / in the opposite direction, and it is the support arm. c provided with a corresponding through-hole in order to be able to fix the level at this point. If you now turn the viewfinder from the upright position to the horizontal position, the support arm c at the two ends of the circular slot b serves as a stop for this movement.
