Abstract

A method of driving a moveable part and, in particular, a drawer by a drive unit and, in particular, an electric drive unit. At least over a partial length of track (S2), forming part of the total track traversed by the moveable part, the force exerted on the moveable part by the drive unit is controlled at a predetermined level.

Independent Claims | See all claims (13)

1. 1. A method of driving a moveable part of an article of furniture which includes a track that can be traversed by the moveable part, the method comprising: providing a drive unit that is capable of applying a driving force to the moveable part over at least a part of the total length of the track, wherein the driving force can be regulated as a function of time from activation of the drive unit, speed of the movable part, current or voltage fed to the drive unit, force opposing movement of the movable part, or distance traveled by the moveable part; and controlling the driving force applied by the drive unit, over at least a part of the total length of the track, so that the driving force applied by the drive unit on the moveable part is closed-loop controlled at a predetermined force unit.
2. 13. A method of driving a drawer of an item of furniture having a track along with the drawer is moveable, the method comprising: providing a drive unit that is capable of applying a driving force to the moveable drawer over at least part of the total length of the track to be traversed by the moveable drawer, wherein the driving force can be regulated as a function of time from activation of the drive unit, speed of the drawer, current or voltage fed to the drive unit, force opposing movement of the drawer, or distance traveled by the drawer; and controlling the driving force applied by the driving unit so that the driving force is closed-loop controlled at a predetermined force value.
