Abstract

Photographic accessories such as, e.g., filters, masks, trick inserts, close-up, split and centre-spot elements have up to now a. exclusively been mounted in front of lenses by means of a thread or bayonet, or b. been mounted by means of guide slots in the lens between the elements or in front of the front element by means of special slide-in carriers in front of the lenses, e.g. by means of their filter thread. In the case of a., a rotary operation is required for mounting, in the case of b., a push-in operation resembling that of a drawer is undertaken transverse to the optical axis. Common to the known operations is that in the rest position the corresponding accessory only lies in a specific plane with respect to the lens. By contrast, the abovementioned accessory slip-on ring permits 1. rapid mounting in the optical axis of the corresponding accessory, 2. such an accessory to be held at different distances relative to the front element, depending on requirements of the picture composition. It is possible in this way, e.g., for pin-hole diaphragms of cup-like construction to be matched to the different circumstances of the dimensions of the depth of the front element relative to the lens mount of different lenses by slipping in to a greater or lesser extent. The operation thus described is clearly visible on the drawing on which the application is based.

Description

Die Erfindung bezieht sich auf einen Steckring aus Metall oder Kunststoff gemäß dem Oberbegriff des Anspruch 1.The invention relates to a plug-in ring made of metal or plastic according to the preamble of claim 1.

Zubehör- und Filterfassungen mit Objektivbefestigung über Gewindeverschraubung oder Bajonette sind bekannt. Bekannt sind ferner Vorsätze, welche es in Art einer Schublade gestatten, Filter-und Zubehör im Winkel von 900 zur optischen Achse einzuschieben.Accessory and filter sockets with lens attachment via threaded screw connection or bayonets are known. Also known are intentions, which are in the form of a Drawers allow filters and accessories to be inserted at an angle of 900 to the optical axis.

Bei keiner der bekannten Befestigungsarten ist es jedoch mit Zubehörvorsätzen gleicher Abmessungen möglich, deren Position unterschiedlichen, den Formgebungen der unmittelbaren Beschaffenheit der Fassung vor der Frontlinse verschiedener Objektive mit gleichem Filtergewinde anzupassen. Lochblenden vor der Frontlinse angebracht würden bei zu weitem Abstand zu dieser Frontlinse, bei ansonsten geeigneten Objektiven vignettieren. Solche Lochblenden müssen daher bei Befestigung nach Stand der Technik unterschiedliche Abmessungen aufweisen, wenn sie an Objektiven mit gleichen Filterbefestigungsabmessungen, jedoch unterschiedlich tief sitzenden Frontlinsen vignettierungsfrei angebracht werden sollen.In none of the known types of attachment, however, it is with accessory attachments the same dimensions possible, their position different, the shapes the immediate nature of the mount in front of the front lens of various lenses adapt with the same filter thread. Pinholes attached in front of the front lens would be too far from this front lens, with otherwise suitable lenses vignette. Such pinhole diaphragms must therefore be attached according to the prior art have different dimensions if they are attached to lenses with the same filter mounting dimensions, However, front lenses with different depths are attached without vignetting should be.

Es stellt sich damit die Aufgabe, ausgehend von den Zubehörbefestigungsarten gemäß dem Stand der Technik, eine Befestigungsbasis zu schaffen, bei welcher Zubehörvorsätze gleicher Abmessungen auch bei unterschiedlichen Frontlinsenabständen variabel positionierbar benutzt, aber auch Zubehörvorsätze nach dem Stand der Technik oder in Kombination beider Arten gemeinsam angebracht werden können.The task is therefore based on the types of attachment of accessories according to the prior art to provide a mounting base in which accessory attachments same dimensions can be variably positioned even with different front lens distances used, but also accessory attachments according to the state of the art or in combination both types can be attached together.

Diese Aufgabe wird durch einen Steckring nach Anspruch 1 aus Metall oder Kunststoff gelöst, welcher mit einer dem Stand der Technik gemäßen Filterbefestigung am Objektiv angebracht wird und dessen Innendurchmesserwandung nach Anspruch 2 u.3 über eine bestimmte Länge als Gleitführung für Steckelemente, zur Bewirkung unterschiedlicher Effekte zur Beeinflussung des Strahlenganges bzw. der Lichttransmission eines Objektives, dient.This object is achieved by a plug-in ring according to claim 1 made of metal or plastic solved, which with a filter attachment according to the state of the art is attached to the lens and its inner diameter wall according to claim 2 and 3 over a certain length as a sliding guide for plug-in elements, to effect different Effects for influencing the beam path or the light transmission of an objective, serves.

Ferner weist dieser Steckring an seiner, der Objektivbefestigung gegenüberliegenden Seite eine Filterbefestigung gemäß dem Stand der Technik nach Anspruch 4 auf, um hier in Kombination mit den steckbaren Verfahren gemäß Anspruch 1 bis 3, auch bekannte Zubehörbefestigung durchführen zu können.Furthermore, this plug-in ring has on its opposite to the lens mount Side a filter attachment according to the prior art according to claim 4 to here in combination with the pluggable method according to claims 1 to 3, also known To be able to carry out attachment of accessories.

Demnach ist diese Gestaltung geeignet, topfförmige Lochblenden in vignettierungsfreie Position vor die Frontlinsen unterschiedlicher Abstände zu den arteigenen Objektivgegebenheiten zu schieben,und nach Anspruch 4 kann noch weiteres Zubehör angebracht werden.Accordingly, this design is suitable for pot-shaped perforated diaphragms in vignetting-free position in front of the front lenses at different distances from the To push specific lens conditions, and according to claim 4 can still further Accessories to be attached.

Besonders vorteilhaft ist diese Gestaltung bei geeigneten Objektiven deshalb, weil, wenn Lochblenden kleineren Durchmessers als der arteigenen Objektivblende, vor der Frontlinse angebracht werden eine höhere Schärfentiefe erzielt werden kann und ein rascher Wechsel durch Ein- und Aug schub zur raschen Sucherbildbeurteilung an einer Spiegelreflexkamera erfolgen kann, ohne daß sich bei Objektiven mit Drehfokussierung deren Fokussierung durch Zubehörbefestigung zwangsweise verstellen muß, da im wesentlichen nur achsiale Kräfte auftreten. Trotzdem kann am Steckring neben den eingesteckten Lochblenden oder anderem Zubehör weiteres Zubehör wie z.B.ein Polarisationsfilter in Kombination nach Anspruch 4 mit Lochblende angebracht werden.This design is particularly advantageous with suitable lenses because if pinhole diaphragms are smaller in diameter than the original lens diaphragm, A greater depth of field can be achieved in front of the front lens and a quick change by pushing in and out for quick viewfinder assessment can be done on a single lens reflex camera without that with lenses with rotary focus adjust the focus forcibly by attaching accessories must, since essentially only axial forces occur. Nevertheless, on the plug-in ring In addition to the inserted perforated panels or other accessories, other accessories such as a Polarization filter can be attached in combination according to claim 4 with a pinhole.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.Die Figuren zeigen im Einzelnen: Figur 1 einen Steckring in perspektivischer Darstellung Figur 2 den Steckring gemäß Anspruch 1 bis 4 in Vierteischnitt mit Lochblende, Filter und Objektiv. - L e e r s e i t e -An embodiment of the invention is shown in the drawing Figures show in detail: FIG. 1 a plug-in ring in a perspective illustration Figure 2 the plug-in ring according to claim 1 to 4 in a four-section with a perforated diaphragm, filter and lens. - L e r s e i t e -
