Abstract
One requirement imposed on a patient table is that it may occupy only a small floor surface area. Therefore, a patient table having a compact base is required. For a variety of applications, moreover, it is desired that the table is also constructed to be very rigid in the direction of adjustment of its height. To this end, the height adjustment system supporting the table is provided with a drive mechanism which consists of two mutually parallel threaded spindles (54, 56) which pass through an associated nut (50, 52) and expand in two mutually opposed directions. The two threaded spindles are preferably driven by a single motor (70). In order to achieve adequate rigidity in the horizontal direction, the hinge is constructed so as to comprise two arms (28, 30) only.
