Claim Text:
1. An electric-motor furniture drive, comprising: a power supply device including a network terminal which is connectable to a network and having an operating state in regular operation of the electric-motor furniture drive and an idle state when the electric-motor furniture drive is not actuated, said power supply device configured for transforming a network-side input voltage into at least one output-side low voltage and having a isolation transformer or a transformer unit for electrical disconnection between a network-connected input side and a low-voltage-providing output side for operating the electric-motor furniture drive, said power supply device constructed as a switched power supply and including an intermediate circuit, a control unit for controlling the switched power supply, and a secondary unit, a manual control for adjusting movable furniture components relative to one another; at least one electric motor which is reversible in a rotational direction; a speed reduction gear connected downstream of the at least one electric motor; and a further gear connected downstream of the speed reduction pear, wherein the power supply device provides at its output an output-side operating voltage in its operating state and provides at its output an output-side idle voltage, instead of the operating voltage, in its idle state, wherein the power supply device includes a load recognition unit having a sensor, and a control block connected to the secondary unit and configured to switch over the output-side operating voltage into the output-side idle voltage, said control block being connected to a reference voltage unit of the secondary unit.
