Abstract: An apparatus for adjusting the height of a base cabinet having a table top thereon includes a bottom plate supporting a lifting assembly, the lifting assembly including a spindle unit with a spindle and a spindle nut mounted on the bottom plate, an upper end of the spindle unit providing a carrying surface, and a single electric motor for driving the spindle unit.

Abstract: An arrangement for height-adjustment, preferably for kitchen tables with base cabinets is designed as a platform comprising a bottom plate (10), on which is mounted a lifting arrangement (13-18) with a carrying surface (11) for an object positioned thereon.

Abstract: An electrical actuator system, especially for adjustable articles of furniture, comprising at least one electric actuator for bringing about the adjustment, a mains based power supply and possibly also rechargeable batteries, a control unit and a hand (10) control with at least one key (17) of a transparent material and/or an area of transparent material surrounding the key. Inside the hand control (10) is a light source located in connection with the transparent material (16). A control of the light source is embodied so that the light source always emits a basic lighting and by touch, movement or activation of a key, the light source is brought to emit an actual operating lighting of the keys.
