Manipulator

1. A device for turning an object about a swivel axis which is stationary in relation to said device, the device comprising: two manipulator modules, each manipulator module including a base part to which, rotatable on a base axis, an upper arm is linked, to which in turn, rotatable on an arm axis, a lower arm is linked, which has an end axis, wherein said base axis, said arm axis and said end axis of each manipulator module intersect with each other in respectively one intersection point, with a connecting line between the intersecting points defining said swivel axis; and a connecting piece supported rotatably on said two end axes is mounted between and directly connected to said two lower arms and provides and/or forms an object holder for the object to be turned.

2. The device according to claim 1 , wherein said two manipulator modules are arranged symmetrically relative to a plane of symmetry between said two intersection points.

3. The device according to claim 1 , wherein said end axes run in a normal plane to said swivel axis.

4. The device according to claim 1 , wherein said object holder is mounted relative to said connecting piece in a movable manner in a direction towards said swivel axis and is fixable in various positions.

5. The device according to claim 1 , wherein said base axes are situated in one plane.

6. The device according to claim 1 , wherein a center of gravity of the object to be turned is located below a level of said swivel axis.

7. The device according to claim 1 , wherein the object to be turned is a patient's stretcher, a bed, a treatment chair, or an examination chair.
