LINSENPASSÜNGLENS FIT
Es ist bekannt, Linsen in der Linsenfassung mittels eines Sprengrings zu siehern. Die bekannten Sprengringe bestanden aus Stahl und hatten einen runden Querschnitt. Der Sprengring mit rundem Querschnitt hatte den Nachteil, daß die Aufnahme für diesen Ring in der Linsenfassung sehr genau gearbeitet sein mußte Ferner mußten an die Fertigung der Sprengringe ebenfalls relativ hohe Anforderungen gestellt werden, damit der Sprengring im eingesetzten Zustand auf dem gesamten Umfang in der Aufnahme anlag; sonst war zumindest auf die Dauer keine zuverlässige Festlegung der Linse in der Fassung gewährleistet. Dureh heftige Bewegungen konnte sieh die Eelativlage des Rings zur Linse verändern, was eine Beeinträchtigung der Bildgüte zur Folge hatte.It is known to use lenses in the lens mount a snap ring to see. The well-known snap rings were made of steel and had a round one Cross-section. The snap ring with a round cross-section had the disadvantage that the recording for this ring The lens mount had to be worked very precisely. Furthermore, the production of the snap rings had to be done Relatively high requirements are also made so that the snap ring in the inserted state was on the entire perimeter in the recording; otherwise, at least in the long run, no reliable fixation of the lens in the frame was guaranteed. Dureh Violent movements could change the relative position of the ring to the lens, which is an impairment the quality of the image.

Der Neuerung liegt die Aufgabe zugrunde, eine Sprengring-Verankerung einer Linse in der Linsenfassung zu schaffen, die die geschilderten Nachteile vermeidet.The innovation is based on the task of a snap ring anchorage to create a lens in the lens mount which avoids the disadvantages described.
Neuerungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß der Sprengring aus Kunststoff besteht und mit einer konischen Facette versehen ist. Die Aufnahme in der Linsenfassung ist in gleicher Weise konisch ausgebildet. Diese Ausbildung des Sprengrings hat den Vorteil, daß er sieh besser, als das beim Stahlsprengring mit rundem Querschnitt der Fall ist, in die konische Aufnahme hineindrüekt und sieh infolgedessen niemals lockern kann. Ferner braucht an die Genauigkeit der Aufnahme, insbesondere hinsichtlich der Lage, nicht die hohe Anforderung wie beim Stahlsprengring gestellt zu werden.According to the innovation, the task set is thereby solved that the snap ring is made of plastic and is provided with a conical facet. The recording in the lens mount is conical in the same way. This training of the snap ring has the advantage that it looks better than is the case with the steel snap ring with a round cross-section, in the conical receptacle pushes in and as a result can never loosen. Also needs to Accuracy of the recording, especially with regard to the position, not the high requirements as with the steel snap ring to be asked.
Der aus Kunststoff bestehende Sprengring nach der Neuerung läßt sieh mit seiner konischen Facette in bekannter Weise leicht herstellen, beispielsweise nach einem Guß-, Preß-, Spritz- oder Spritzgußverfahren.The plastic snap ring according to the innovation lets you see with its conical facet Easily manufacture in a known manner, for example by a casting, pressing, injection or injection molding process.
Die Herstellung des Sprengrings nach der Neuerung bedeutet daher keinen besonderen Aufwand.The production of the snap ring according to the innovation therefore means no special effort.
Anhand der Zeichnung, in der eine Ausführungsform des Sprengrings nach der Neuerung beispielsweise dargestellt ist, sei der Neuerungsgedanke näher erläutert.Based on the drawing, in which an embodiment of the Snap ring is shown after the innovation, for example, the idea of the innovation will be explained in more detail.
1 bedeutet eine Linsenfassung, in die eine Linse 2 eingesetzt ist. Als Anlage dient fassungsseitig die ringförmige Auflagefläche 3. Zur Halterung der Linse ist eine konische Aufnahme 4 in der Linsenfassung 1 angeordnet, in die ein Sprengring 5 eingesetzt ist. Dieser Sprengring 5 weist neuerungsgemäß eine konische Facette auf, die der Aufnahme 4 angepaßt ist. Der Sprengring 5 !besteht aus Kunststoff,1 means a lens mount in which a lens 2 is used. The ring-shaped contact surface 3 on the frame side serves as a support to hold the lens a conical receptacle 4 is arranged in the lens mount 1, into which a snap ring 5 is inserted. This snap ring 5 has according to the innovation conical facet which is adapted to the receptacle 4. The snap ring 5! Is made of plastic,
