Device including moveable support for examining persons

A device for examining persons, comprising:

• a medical examination device having an examination space,
• a support for a person to be examined, and
• a drive assembly for moving the support in a direction of movement, in such a manner that a person to be examined who is present on said support is moved into and out of the examination space said drive assembly comprising:
• a gear wheel driven by driving device, the gear wheel meshing with a toothed rack connected to the support for moving the toothed rack relative to the gear-wheel when the gear wheel is being driven,
• the drive assembly including an auxiliary moving assembly for moving the gear wheel in the direction of movement when the gear wheel is being driven, at a speed which is lower than a speed at which the support is being moved, the auxiliary moving assembly including:
• a driven auxiliary gear wheel, which meshes with a first auxiliary toothed rack for moving said auxiliary toothed rack with respect to said auxiliary gear wheel when said auxiliary gear wheel is being driven, with the gear wheel being journalled with respect to said auxiliary toothed rack,
• a further auxiliary toothed rack moving in the direction of movement at a speed which is lower than the speed of the first auxiliary toothed rack and the gear wheel that is journalled therein, with said further auxiliary toothed rack being in mesh with said gear wheel.

A drive mechanism for moving a support in a direction of movement, in such a manner that a person to be examined who is present on said support is moved in a direction of movement into and out of a examination space of a medical examination device, said mechanism comprising:

• a first gear wheel driven by a motor, the first gear wheel meshing with a first toothed rack connected to the support such that the first toothed rack and the support move in the direction of movement relative to the first gear wheel when the first gear wheel is being driven,
• a second toothed rack, the first gear wheel being mounted to the second toothed rack such that the second toothed rack and the first gear wheel move in the direct of movement when the first gear wheel is being driven,
• a third toothed rack element,
• second and third gear wheels with a common axis of rotation, a larger of the second and third gear wheels meshing with the second toothed rack element and a smaller of the second and third gears meshing with the third toothed rack element.
