Contessa-Nettel A. G. in Stuttgart. Vorrichtung zur Führung von Kassetten oder Mattscheiben an photographischen Kameras. Contessa-Nettel AG in Stuttgart. Device for guiding cassettes or focusing screens on photographic cameras.
Die Erfindung betrifft eine Vorrichtung zur Führung von Kassetten oder Mattscheiben photograpnischer Kameras oder ähnlicher Vorrichtungen und bezweckt, die sonst zur Befestigung einer Führungsbann üblichen Teile, wie Schrauben, Nieten o. dgl.,, zu ersparen und trotzdem in einfachster und zuverlässigster Weise die Führung zu ermöglichen.The invention relates to a device for guiding cassettes or focusing screens photographic cameras or similar devices and the purpose of which is otherwise for attachment a guide spell usual parts such as screws, rivets o. The like., to spare and nevertheless to enable the leadership in the simplest and most reliable way.
Um diesen Zweck zu erreichen, sind die Teile der Fülirungsbahn S-förmig ausgebildet,In order to achieve this, the parts of the Fülirungsbahn are S-shaped,
so daß außer der Führungsbahn eine um· die inneren Kanten des Kameragehäuseblendrähmens herumgreifende Leiste vorhanden ist. Um die Innenfläche der umgebogenen Randleisten' mit der Kameragehäuseinnenflächie möglichst in gleiche Ebene zu bringen, ist um die Blendrahmenöffnung herum innerhalb des Gehäuses eine Ausfräsung vorhanden, in welche sich die Randleisten einlegen, wodurchso that, in addition to the guideway, there is one around the inner edges of the camera housing frame there is a wraparound bar. Around the inner surface of the bent edge strips' is to be brought into the same plane as possible with the inner surface of the camera housing there is a cutout around the frame opening inside the housing, in which insert the edge strips, whereby
ίο der Führungsteil festgehalten wird.ίο the guide part is held.
Ein Ausführungsbeispiel der Erfindung ist zeichnerisch dargestellt, und zwar zeigen Abb. r eine Aufsicht auf die Kamerarückwand mit umgelegten Randleisten des Kassettenführungsteiles, die Leisten in nichtumgebogenem Zustande! strichpunktiert wiedergegeben, Abb. 2 einen Teilquerschnitt der Abb. 1.An embodiment of the invention is shown in the drawing, namely show Fig.r a plan view of the rear wall of the camera with folded edge strips of the cassette guide part, the lasts in a non-bent condition! shown in dash-dotted lines, Fig. 2 shows a partial cross-section of Fig. 1.
Bei dem Kassetten- oder Mattscheibenführungsteil α ist die Innenfläche derart herum-In the case of the cassette or ground glass guide part α , the inner surface is so around-
ao gebogen oder ausgestanzt, daß sich Randleisten a1 bilden. Diese werden um die Blendrahmenöffnungen der Kamerarückwand b gebogen. Letztere hat rings um die Blendrahmenöffnung eine Ausfräsung b1, in die sich die umgebogenen Randleisten einlegen. Dadurch vergleicht sich die Oberfläche der letzteren mit der Innenwand des Kameragehäuses, wodurch eine günstige Befestigung des Balges möglich ist.ao bent or punched out that the edge strips a 1 are formed. These are bent around the frame openings of the camera rear wall b. The latter has a cutout b 1 around the frame opening, into which the bent-over edge strips are inserted. As a result, the surface of the latter compares with the inner wall of the camera housing, which enables the bellows to be attached conveniently.
