Abstract
The invention relates to a furniture arrangement (200) comprising at least two pieces of furniture (1, 1′), each respectively having an electromotive furniture drive (100, 100′) for adjusting at least one movable part (4, 5) of each at least two pieces of furniture (1, 1′), wherein each electromotive furniture drive (100, 100′) comprises a) at least one adjusting drive (7, 7′; 8, 8′) with respectively at least one electric motor, a speed-reducing gear mechanism coupled thereto and to which an output element is drivingly coupled, said output element being linearly displaceable and/or can be rotated, and b) at least one control device (9, 9′), wherein c) the furniture arrangement (200) comprises an operating unit (10) for actuating all the electric motors of the adjusting drive (7, 7′; 8, 8′) of the electromotive furniture drive (100, 100′). Said control devices (9, 9′) of electromotive furniture drives (100, 100′) are equipped with detection means for detecting actuation-specific values such as the motor current, motor operating voltage, motor speed or similar of the electric motor of the at least one associated adjusting drive (7, 7′; 8, 8′) and comprising at least one controlling device for variably controlling the operating voltage of the electric motor of the at least one associated adjusting drive (7, 7′; 8, 8′) for a parallel control of the at least one adjusting drive (7, 8) of one of the electromotive furniture drives (100) and of the at least one adjusting drive (7′, 8′) of the other electromotive furniture drive (100′). Said control devices (9, 9′) are designed to communicate with the operating unit (10, 10′) and between themselves, or to communicate between themselves by means of the operating unit (10, 10′) with at least one transmission path (21, 22, 23, 23a, 23′). The invention also relates to the parallel control of at least two electromotive furniture drives (100, 100′) of a furniture arrangement (200).

13. A furniture arrangement, comprising:
-
at least two pieces of furniture; at least two electromotive furniture drives respectively provided for the two pieces of furniture for adjusting at least one movable part of the at least two pieces of furniture, each said electromotive furniture drive comprising at least one adjusting drive having at least one electric motor, a revolution speed reducing gear mechanism coupled to the at least one electric motor and coupled in driving relationship to an output element for linear displacement and/or rotatably movement of the output element, and at least one control device; and an operating unit configured to actuate the electric motors of the adjusting drives of the electromotive furniture drives, wherein the control devices of the electromotive furniture drives have detectors for detecting drive-specific values of the at least one associated adjusting drive and with at least one final control device for a variable setting of an operating voltage of the electric motor of the at least one associated adjusting drive for parallel control of the at least one adjusting drive of the one electromotive furniture drive and the at least one adjusting drive of the other electromotive furniture drive, wherein the control devices are configured for communication with the operating unit and among each other, or for communication among each other via the operating unit with at least one transmission link. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for the parallel control of at least two electromotive furniture drives of a furniture arrangement, each of the electromotive furniture drives having an adjusting drive, comprising the steps of:
-
detecting current adjusting positions of operated motors of the adjusting drives to be controlled in parallel; communicating the current actual positions of the operating motors of the adjusting drives to be controlled in parallel between control devices of the electromotive furniture drives and comparing the current actual positions; and controlling the operated motors of the adjusting drives in parallel by throttling a recognized advancing motor of the adjusting drives to be controlled in parallel, or accelerating of a trailing one of the motors to a higher speed. - View Dependent Claims (22, 23, 24, 25, 26)
