ABSTRACT:
The invention relates to a displacement system for ophthalmologic examination units constituted of an instrument base section and an accessory section for mounting three ophthalmologic devices, said accessory section being connected by two lever means to said base section to enable displacement of the former relative to the latter from a first end position via an intermediate position into a second end position in the latter two positions relative to the said first end position the accessory section is displaced in parallel and at right angles relative to the base section so that the accessory section projects past over the base section. In this manner the opthalmologic devices are brought into an operation position in front of a patient and operator. A further lever system in combination with the lever means pivots a head rest to a patient in the intermediate and second end position, which head rest remains unchanged even when the ophthalmologic devices are changed for operation.
