Description
Beidäugige Lupe mit Beleuchtungsmitteln, besonders für die Zwecke der Augenuntersuchung Gegenstand der Erfindung ist ein Apparat, welcher zur gleichzeitigen Betrachtung beider Augen dient. Was diesen neuen Apparat gegenüber den bereitsbekanntenbesondersunterscheidet, ist die Anordnung der Beleuchtungskörper an je einem auf der zugehörigen Fassung jeder Vergrößerungslinse angeordneten Drehring, so daß man durch Verstellung dieser Drehringe in der Lage ist, störende Lichtreflexe bei der Untersuchung auszuschalten. Außerdem sind die Beleuchtungskörper von den Drehringen lösbar, wodurch sie jederzeit ausgewechselt werden können.Ambidextrous magnifying glass with lighting means, especially for the purpose the eye examination The subject of the invention is an apparatus, which for simultaneous Consideration of both eyes serves. What distinguishes this new device from the already known ones is the arrangement of the lighting fixtures on each one on the associated socket Each magnifying lens arranged rotating ring, so that you can adjust this Bezel is able to turn off annoying light reflections during the examination. In addition, the lighting fixtures are detachable from the rotating rings, which means they can be removed at any time can be exchanged.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt.In the drawing, the subject matter of the invention is in one embodiment shown.
Abb. i zeigt die Vorderansicht. O sind die beiden aplanatischen Vergrößerungslinsen; von welchen jede mit einer Fassung B umgeben ist. Um diese ist ein verschieb- bzw. drehbarer Ring E mit Schlitz, gelegt, in welchen hinein die Beleuchtunskörper F gesteckt werden. Die die Beleuchtungskörper F mit Strom speisenden Leitungsschnüre laufen von jenen durch den die beiden Linsen Q verbindenden hohlen Querbalken C bis zum Kopfband K, über dieses hinweg durch Ösen bis zu einer elektrischen Taschenbatterie oder Lichtleitung. Die beiden Linsengehäuse B sind durch den hohlen Querbalken C verbunden, welcher eine Vorrichtung D trägt, um den Abstand der beiden Ljnsen voneinander j e nach Bedarf einstellen zu können. Die Stifte !17 am unteren Teil der Linsengehäuse B dienen zum Festhalten eines Hauchschützers.Fig. I shows the front view. O are the two aplanatic magnifying lenses; each of which is surrounded by a socket B. To this is a shift or rotatable ring E with slot, into which the lighting elements F be plugged. The power cords that feed the lighting fixtures F run from those through the hollow crossbeam C connecting the two lenses Q to the headband K, over this through eyelets to an electric pocket battery or light guide. The two lens housings B are through the hollow crossbar C connected, which carries a device D, by the distance between the two Ljnsen from each other to be able to adjust as required. The pins! 17 on the lower part of the lens housing B are used to hold a breath protector in place.
Abb. 2 zeigt den Apparat in Seitenansicht. Aus dieser Darstellung ist die Anordnung eines am inneren Rand jedes Gehäuses B dem Beleuchtungskörper F gegenüber angebrachten halbkreisförmigen Spiegels I zu ersehen, welcher das von dem Beleuchtungskörper F ausgestrahlte Licht auf das zugehörige Auge reflektiert und gleichzeitig als Nasenbügel den festen Sitz der Lupe gewährleistet. Außerdem ist aus Abb. 2 die Verbindung des Drehringes E mit dem Beleuchtungskörper F und deren Anordnung auf der Fassung B ersichtlich.Fig. 2 shows the apparatus in side view. From this representation is the arrangement of a on the inner edge of each housing B the lighting fixture F opposite attached semicircular mirror I can be seen, which the of the lighting fixture F reflected light emitted to the associated eye and at the same time, as a nose clip, ensures that the magnifying glass sits securely. aside from that is from Fig. 2 the connection of the rotating ring E with the lighting fixture F and their arrangement can be seen on socket B.
Abbb.3 zeigt in einer besonderen Teilansicht nochmals die Anordnung der aplanatischen Vergrößerungslinsen- mit Fassung B und Spiegel J.Fig. 3 shows the arrangement again in a special partial view the aplanatic magnifying lens with frame B and mirror J.
