Verbesserung an Se lip ruf gerät en.Improvement on lip call devices.

Die Erfindung "bezieht sich auf solche Sehprüfgeräte, bei denen jedem Auge durch eine Lupe hindurch eine Testtafel in sehr großer Entfernung dargeboten wird, γ/obei das Ie st tafelpaar Y/echselbar gegen andere Paare auf einer drehbaren Eevolverscheibe oder einem ähnlichen Träger angebracht ist.The invention "relates to such vision testing devices in which a very large test chart through a magnifying glass for each eye Distance is presented, γ / whether the Ie st table pair Y / can be changed is attached to other pairs on a rotatable Eevolverscheibe or a similar support.

G-elegentlich ist es erforderlich, weitere Testtafelpaare anzuwenden, als auf dem Träger üblicherweise vorgesehen sind und untergebracht werden können. Demzufolge wird erfindungsgemäß vorgeschlagen, den mehrere Tafelpaare enthaltenden Testträger auswechselbar zu gestalten. Um das ohne v/eitere Bedienungsmaßnahnien zu erreichen, ist es ein.Teil der Erfindung, daß der Träger drehbar zwischen zwei Kugeln gelagert ist, von denen mindestens eine in Bichtung der Drehachse federnd im Gehäuse gegenüber der anderen lüxgel'- ortsfest gelagert ist, und zwischen die der Testträger ohne weiteres eingeschoben werden kann, so daß eine selbsttätige Drehlagerung eintritt. Ebenso leicht kann der Testträger aus dieser Kugellagerung γ/ieder herausgezogen und durch einen anderen Testträger ersetzt werden. " ..Occasionally it is necessary to use further pairs of test tables, than are usually provided and can be accommodated on the carrier. Accordingly, according to the invention proposed to make the test carrier containing several pairs of panels exchangeable. To that without further operating measures To achieve, it is ein.Teil of the invention that the carrier is rotatable is mounted between two balls, at least one of which is resilient in the direction of the axis of rotation in the housing opposite the other lüxgel'- is stationary, and between which the test carrier without further can be pushed in, so that an automatic pivot bearing entry. The test carrier can just as easily be pulled out of this ball bearing and replaced by another test carrier be replaced. "..

In der ligur ist ein Beispiel gemäß der Erfindung wiedergegeben worden.In the Ligur an example according to the invention is given been.

Auf der G-rundplatte 1 ist in einem - G-e lenk Z neigbar'ein Gehäuse angebracht, in dem ζγ/ei Einblicklinsen vorgesehen sind. ITur eine dieser Linsen ist gezeichnet und mit 4 benannt worden. Das Testpaar befindet sich auf der Eevolverscheibe 6 oberhalb und- unterhalb der Zeichenebene; es wird durch die Linsen 4 über den Plan-On the base plate 1, a housing is attached in a - Ge joint Z inclinable, in which ζγ / ei viewing lenses are provided. Only one of these lenses has been drawn and named 4. The test pair is located on the Eevolverscheibe 6 above and below the plane of the drawing; it is through the lenses 4 over the plan
