  • Patent number: 5410767
    Abstract: An examination table has a patient support plate attached to a floor stand so as to be movable relative to the floor stand in the longitudinal direction of the support plate. The support plate is generally rectangular, and has one side which is longer than the other. The support plate is moved relative to the floor stand by a motorized articulated lever, having first and second arms. Respective ends of the two arms are joined so as to be rotatable around a second shaft, and an opposite end of the first arm is rotatable around a first shaft connected to the support plate, and an opposite end of the second arm is rotatable around a third shaft attached to the floor stand. All three shafts are oriented perpendicularly to a horizontal plane in which the support plate is disposed, so that the first and second arms always move in a plane parallel to this horizontal plane.

  • Patent number: 4716581
    Abstract: The invention relates to an x-ray examination apparatus comprising a stand and a support mounting which are adjustable in space, or relative to one another, such that a curved support, mounted on the support mounting is three dimensionally adjustable. At one end of the curved support a radiation source is mounted and at its other end an image layer carrier is mounted so that these units are aligned relative to one another. The support is rotatable about a first shaft. For each of the translational and rotational movements, a drive is provided. In order to obtain an x-ray examination apparatus which is simple in construction and therefore inexpensive, the support is nondisplaceably mounted on the support mounting and is pivotally mounted about an additional shaft disposed horizontally and vertically to the first shaft on the front end of the support mounting.

  • Patent number: 4061324
    Abstract: A patients support table which is displaceable in two directions. In the inventive arrangement, when a patients support arrangement of the table is removable from a pedestal and drive motors are located therein, there are provided compressed air couplings between the pedestal and the patients support arrangement. In the event of minor sealing leaks of these couplings, some compressed air will escape into the atmosphere which is not of any significance.
