  • Object of the present invention is to provide a telescopic lifting column of a furniture part, which has a large stroke size in a small space, is simple and with the maximum efficiency can be achieved with a given power requirement.
  • the telescopic lifting column has a first column profile, a first rotatable spindle which is indirectly connected to the first column profile via a rotationally secured first spindle nut, a second rotatable spindle which can be moved to the first spindle in the longitudinal direction of the first spindle and which has a rotationally secured second Spindle nut is indirectly connected to a second pillar profile in operative connection, in which the first pillar profile in the longitudinal direction of the first spindle is movable, a third pillar profile, the second spindle surrounds and in which the second column profile in the longitudinal direction of the second spindle is movable and a drive unit, wherein the drive unit of the telescopic lifting column is coupled to a drive tube, in which the first spindle with the same direction of rotation of the drive tube and in the longitudinal direction relative to the drive tube movable is, wherein the second spindle is supported by a thrust bearing in the footer of the lifting column.
  • the drive tube, the first spindle and the second spindle are coupled together such that the drive tube, the first spindle and the second spindle at the same speed and in the same direction of rotation are driven in rotation, wherein the rotation is a positive or negative longitudinal extent of the drive tube, first spindle and second spindle unit in the longitudinal direction relative to the drive tube results. Also, by the simultaneous rotation of the spindles and the drive tube uniform loading of the components of the lifting column is promoted in all phases of Teleskopiervorgangs.
  • the first spindle is formed in a preferred embodiment of the invention as a hollow spindle and the second spindle as a full spindle, so that the hollow spindle in the drive tube and the full spindle in the hollow spindle can be moved.
  • the rotationally secured spindle nuts and the first and second of the column profiles are coupled together according to a further preferred embodiment variant via a driver.
