ABSTRACT:
The invention is directed to an arrangement for tiltably journalling an ophthalmologic treatment and/or examining apparatus. The arrangement includes a mount and an arcuate guide fixedly attached at an end thereof to the mount. Guide elements are mounted on the apparatus for movably guiding the apparatus along the arcuate guide to tilt the apparatus to a desired position. A pressure-spring device has a first end pivotally connected to the apparatus and a second end pivotally connected to the mount whereby the weight of the apparatus is compensated as the apparatus is tilted when moved along the arcuate guide. The arrangement further includes a mechanism for blocking and deblocking the spring action of the pressure-spring device. A lever assembly imparts a tilting movement to the apparatus. The lever assembly has a first pivot connection whereat the Lever assembly is connected to the mount and a second pivot connection whereat the lever assembly is connected to the apparatus.
