A lifting column includes at least five column elements which are at least partly nested, and a first and a second drive arrangement. The first drive arrangement is configured to move the three innermost column elements relative to one another. The second drive arrangement is configured to move the three outermost column elements relative to one another.

Nested lifting columns

A telescopic lifting unit with a first segment, a second segment, and a third segment. The first and second segments may be displaced relative to one another, and the second and third segments may be displaced relative to one another. The first and second segments may be moved relative to one another by a motor unit, and the second and third segments may be moved relative to one another by a cable hoist.

Telescopic lifting unit

A telescopic column includes at least two telescopic elements movable with respect to one another between two end positions and at least one damper that is configured such that, prior to reaching at least one of the end positions, a force slowing the relative movement of the telescopic elements is exerted on at least one of the telescopic elements.

Telescopic column

A telescopic column includes at least two linearly movable telescopic elements and a drive system. The drive system includes a drive unit having a first clutch element and an output unit having a shaft, a windable connecting element and a second clutch element connected to the shaft such that the clutch element and the shaft rotate together. The drive system includes a brake unit configured to transmit a retaining force onto the second clutch element and configured such that applying a drive moment to the first clutch element reduces the retaining force and allow the telescopic elements to move relative to each other. The brake unit is further configured such that applying an output-side torque to the second clutch element increases the retaining force acting on the second clutch element.

A telescopic column includes a first telescopic element and a second telescopic element moveable linearly with respect to one another, at least one drive unit connected to the first telescopic element, at least one connecting element configured to transmit a force from the drive unit to the second telescopic element, a monitoring unit configured to detect an operating parameter of the connecting element, and a switch configured to send a signal to the monitoring unit in response to the detected operating parameter being outside a predetermined range.

A lifting column includes a first column element and at least one second column element, the at least one second column element being movable relative to the first column element, and at least one damping unit. The damping unit is deformable by a force that acts on an upper side of the lifting column in at least one operating configuration of the lifting column such that the force is at least partly transmitted through the damping unit to a drive of the lifting column.

Lifting column

A table for supporting a recumbent patient includes at least one tabletop unit, at least one ground contact unit for supporting the tabletop unit, a first and at least one second adjustment unit for changing a spacing between the ground contact unit and the tabletop unit, and at least one first guide unit for guiding movement of the tabletop unit relative to a the ground contact unit, where at least a part of the guide unit is disposed between the first and the at least one second adjustment unit.
