  • Patent number: 6105909
    Abstract: A stand for a device, which is to be movably arranged, has a first stand part and a second stand part, which is movable relative to the first stand part, and which includes a pivot arm, pivotable around a pivot axis (A2) and jointed to the first stand part. An energy storage device is provided, which exerts at a fixed point of action of the pivot arm a force directed to an abutment point of the energy storage device on the first stand part. The pivot axis (A2) and the abutment point define a vertical plane, the abutment point being spatially fixed relative to the first stand part during a pivoting of the pivot arm. A cord parallelogram coupling the motion of a first stand arm and a second stand arm includes a closed cord length running around two deflecting rollers, and has a rod section between the deflecting rollers. A linear slide and pivot unit is arranged between a mounting arm and the movably arranged device and makes possible displacements of the center of gravity of the movably arranged device.
