DESCRIPTION

Furniture arrangement and procedure for the parallel control of two electromotive drives for furniture of a furniture arrangement

The invention relates to an arrangement of furniture with at least two furniture according to the preamble of claim 1. The invention relates to a method for the parallel control of at least two electromotive drives for furniture of a furniture arrangement.

The furniture with several support surfaces for the support of a person who is in the furniture are very widespread and are known, for example, as beds, sofas, armchairs or similar. They have at least one mobile support surface, which is positioned displaceably with respect to at least one other support surface. The movable support surface is, for example, a back piece or / and a leg piece, which is movable with at least one electromotive drive for furniture. For this, the support surface can be rotatable, movable, or both by suitable fittings. It is also possible that a base element, for example a bed frame, is executed in height-adjustable way by means of one or more furniture drives.

An electromotive drive for furniture comprises at least one electric motor that is often configured as a direct current motor provided with brushes. A gear is coupled to the motor, normally using a direct current motor with reduction gear. In addition, the electromotive drive for furniture comprises a control element and a control device. The control element can be configured with a wired or wireless connection, and has a certain number of buttons, with which the transmission takes place from a control serial to the electric control of the respective motor, in the respective direction of rotation.

Furniture arrangements are furniture arrangements, for example two adjacent beds or double beds. In this, each adjustable furniture is usually equipped with an electromotive drive for furniture, with at least one adjustment drive, a control device and a control element.

A number of motors are connected to a number of controls, and together form a set of drives, which is also designated as an electromotive drive for furniture. A three-engine bed has a set of drives (furniture drive) with three adjustment drives. There are also adjustment drives with the integrated control, to which more drives can be coupled.

In document DE 93 194 84 U1 two single beds with a respective electromotive drive for furniture are described. The drives for furniture, or the sets of drives are connected to each other according to the control technique through a conductor, additional contacts are provided for the conduction of switching signals to the power supply connections. In this, it is possible to control with one control unit the adjustment drives of the two electromotive drives for furniture, or of the drive sets.

A synchronization control of adjustment drives comprises at least two adjustment drives of a joint set of drives (electromotive drive for furniture), with a joint control device. For example, for height adjustment of the table of a table with two adjustment drives, both adjustment drives are connected and move simultaneously. In this, the synchronization control of drives serves so that both adjustment drives have the same travel speed, so that no inclined position of the table of the table takes place. If the motor of one of the adjustment drives has, for example, a lower rotation speed, due to a higher load, than the motor of the other adjustment drive, then the faster rotation speed of the motor is normally reduced to through appropriate measures of the common control device. This reduces, for example, the faster engine speed by means of PWM (pulse duration modulation).

Unlike in a synchronization control, in a parallel control of at least two adjustment drives, to each one a set of drives belongs, both move simultaneously, that is, in parallel. Each adjustment drive has its own control device.

Depending on the state of the art, several sets of drives can only be hard connected to each other, since

- the mounting effort is extremely increased (additional plug connections in the control of each one, additional cable connections between the controls, additional wiring mounting effort between two or several pieces of furniture).

- the programming effort is increased (the synchronization controls according to the state of the art are executed with microprocessor control, the communication with another control must be adapted, for example, according to the bus union criteria).

In this, each set of drives is placed in a piece of furniture (for example in two single beds). Several sets of drives can be placed in a piece of furniture (for example in a double bed or in a chain of several lifting tables).

The objective of the present invention is to achieve an improved arrangement of furniture, with parallel control, of at least three electromotive drives for furniture, that is, sets of drives.

This objective is achieved by the arrangement of furniture with the features of claim 1.

Another objective is to make available an improved procedure to control in parallel.

This objective is achieved by means of a procedure with the characteristics of claim 9.

The control devices of the electromotive drives for furniture are equipped with detection means for capturing specific values of the motors, such as the motor current, the operating voltage of the motor and the revolutions of the electric motor of the at least one drive of setting for parallel control, and can communicate with each other and with the control unit, or with each other through the control unit. This results in a simple solution, and the same drive sets can be connected in parallel for furniture control.

Accordingly, a furniture arrangement according to the invention comprises at least two furniture with a respective electromotive drive for furniture, for the displacement of at least one movable part of each of the furniture, at least two, each electromotive drive for furniture presenting:

a) at least one adjustment drive, with at least one respective electric motor and a speed reduction gear coupled therewith, by means of which a drive element can be coupled and moved linearly, and / or can be rotatably moved, and

b) at least one control device,

c) presenting the furniture arrangement a control unit for the actuation of all electric motors of the adjustment drives of the electromotive drives for furniture.

The control devices of the electromotive drives for furniture are configured with detection means for capturing specific values of the motors, such as the motor current, the operating voltage of the motor and the revolutions, or the like, of the electric motor of a corresponding adjustment drive, at least one, and with at least one adjustment device for the variable adjustment of the operating voltage of the electric motor of a corresponding adjustment drive, at least one, for a parallel control of the adjustment drive, at least one of one of the electromotive drives for furniture, and of the adjustment drive, at least one of the other electromotive drive for furniture. The control devices are configured with at least one track link for communication with the control unit and with each other, or for communication with each other through the control unit.

This allows a simple connection of the control signals that start from a certain number of buttons with the corresponding furniture, or with the corresponding set of drives.

This is advantageous when the road link, at least one, is configured bi-directionally. Each set of drives has a bi-directional link to the control unit, or also to a certain number of control units, as well as to a certain number of sets of drives, or electromotive drives for furniture.

In one configuration, at least one control device is configured correspondingly to the specific values detected in the drive, for the transmission of the corresponding signals through at least one track link. With this it is possible to communicate easily.

For this, it is also advantageous when each additional control device, and the control unit, are configured to receive the corresponding signals transmitted by the control device, at least one.

In another configuration it is provided that at least one control device has a program for the variable adjustment of the operating voltage of at least one electric motor of the adjustment drive, at least one, through which a simple adjustment of the a speed of rotation of the electric motor.

In addition, it is provided that the adjustment device for the variable adjustment of the operating voltage of the electric motor of the corresponding adjustment drive, at least one, is configured with a PWM control, or / and with at least one electric resistor switchable in series with The electric motor

Advantageously, the control devices can communicate with each other when the control device, at least one, of one of the electromotive drives, is coupled through a track link with the

control device, at least one, of another of the electromotive drives.

The road links can be configured wirelessly or / and by cables. With this, it is also possible to use different sets of drives.

Each set of drives, or each electromotive drive for furniture has a control program. All control programs are configured to communicate with each other via the bi-directional link. Thus, an exchange of the adjustment parameters (travel, angle, current, voltage) of several "sets of drives" between sf can take place advantageously. Communication can take place directly between the controls or / and through the manual switch as a joint communication center.

A method according to the invention for the parallel control of at least two electromotive drives for furniture of the furniture arrangement described above presents the following steps of the procedure: (S1) capture of the current adjustment positions of the driven motors of the drives of setting to control in parallel; (S2) communication between the control devices of the actual actual positions of the driven motors of the adjustment drives to be controlled in parallel, and comparison of those actual actual positions; and (S3) parallel control of the driven motors of the adjustment drives to be controlled in parallel, by decreasing the power of a motor, identified as advanced, of the adjustment drives to be controlled in parallel, or accelerated motor acceleration at a higher turning speed.

In one embodiment, in the second step (S2) of the procedure, the actual positions are compared with previously established values, for example values from a table. The values of a table are advantageous, since they can be previously set easily.

In another embodiment, it is foreseen that in the third step (S3) of the procedure a decrease in the power of the motor identified as advanced, or an acceleration of the respective delayed motor, with the intensity of a value to be established previously, for example, the value contained in a table. Since the values in the table have been elaborated previously, a calculation or an establishment is not necessary, for example by means of algorithms, which saves time.

In another embodiment, in the second step (S2) of the procedure the communication between the control devices and the control unit takes place, or between one of the control devices and the control unit, through which the field of application has been extended.

The invention is explained in more detail according to the attached drawings. Shows:

Figure 1 shows an example of execution of a furniture 1 according to the invention. Schematic perspective views of a control unit 10, 10 'are shown in Figures 2 and 2a.

The furniture 1 is represented here as a bed, and has at least one support element 3 for the accommodation of objects, a padding, a mattress M and / or a person. The support element 3 is configured as a grid of slats, as a flat support surface or the like, and is placed on a base element 2, here a frame with legs, for the coupling of the furniture 1 on a location, by example a floor.

The support element 3 has a back part 4 and a leg part 5, which are positioned displaceably with respect to the support element 3 and / or another support element, or with respect to the base element 2. This movable arrangement is made here by means of a so-called "movement hardware 6". The movement is set in a scrollable and / or rotating way.

The furniture 1 also has an electromotive drive 100 for furniture, which comprises two adjustment drives 7 and 8, a control device 9 and a control unit 10. The control unit 10 is executed in this example as wireless.

The backrest part 4, supported in a mobile manner, and the leg part 5 are respectively coupled with an adjustment drive 7, 8. Thus, the backrest part 4 is coupled with the adjustment drive 7. For the movement, or for the adjustment of the piece 5 for the legs, the adjustment drive 8 is provided.

The adjustment drives 7, 8 are configured as linear drives. The linear drives have an electric motor, or several of them, being coupled to each motor a gear speed reducer with at least one step. Another gear can be coupled to the speed reduction gear, for example in the form of a threaded spindle gear, which generates a linear movement of a drive element from the motor rotation movement. The last gear element, or another element connected to it, configures the drive element. The drive element of the respective adjustment motor is connected with the respective piece of furniture (backrest piece 4, leg piece 5), or alternatively with a construction piece attached to the base frame 2, so that in an operation of the electric motor of the respective adjustment drive 7, 8, the movable construction parts 4, 5 are relatively displaced from each other, or in relation to the base frame 2.

The adjustment drives 7, 8 are connected to the control device 9 through a drive conductor 100a, as shown for example in Figure 4. That drive driver 100a can be executed, for example, as a plug-in joint. by cable. The control device 9 has a power unit, not shown, which provides the electric power, for example from the network, for the adjustment drives 7, 8. For this, the control device 9 can be connected in this example with a network connection through a network plug, through a network cable. The network cable is not represented, but it is easily imaginable. The mains plug conducts the mains voltage from the input side, through the mains cable, to the power supply unit of the control device 9, which supplies the secondary side with a reduced voltage in the form of a continuous voltage, and transmits it to a motor regulation, also not shown, with control switches.

Alternatively to this, the control device 9 is preceded by a network-dependent voltage supply, not shown in more detail, with a network input and with a reduced voltage network output on the secondary side, which feeds the reduced voltage across the conductor 9d, in the form of a continuous voltage.

The control unit 1 has also been assigned a control unit 10, 10 ', with whose control elements 12, 13 (see Figure 2) the adjustment drives 7, 8 can be controlled through the control device 9.

The control unit 10 is equipped, according to Figure 2, with a transmission device, or with a transmission / reception device, for a wireless transmission. The wireless transmission may be a wireless link 23, 23 '(see Figures 5, 5a) with radio transmission, optical transmission (for example infrared) or / and an ultrasonic transmission, the control device 9 being equipped with a respective corresponding transmission unit 9a, 9'a (see, for example, figure 5).

In another embodiment, the control unit 10 'is executed with a control conductor 18 in the form of cables, which shows Figure 2a. In this, the control conductor 18 can be connected to the control device 9, for example by plug. This is represented for example in Figure 4a.

The control unit 10, 10 'is provided with control elements 12, 13, which are provided for the control of a respective adjustment motor 7, 8. The control elements 12, 13 are made as push-buttons. For example, the control elements 12 serve to raise the respective movable part of the furniture, and the control elements 13 to lower it. Control units 10, 10 'for six adjustment drives are shown in figures 2 and 2a.

In addition, the control unit 10, 10 'is equipped with a signaling element 14, for example a light-emitting diode. The signaling element 14 serves, for example, for the operation signaling, or for acknowledgment of receipt, fault signaling, etc.

An additional element 15, which may be composed of several control elements or / and a combined control element, is used for a so-called "memory function" of the adjustment motors 7, 8.

In addition, additional functions, such as a reading lamp or / and a heater, can be operated by other additional control elements 16, 17.

Additional control elements 15, 16, 17 may be executed as push-buttons or / and switches.

When a control element 12, 13 is operated, a control signal is transmitted to the control device 9, via the link 23, 23 ', wirelessly or by cable, for the control of the corresponding adjustment motor 7, 8 The control device 9 has control switches with switching elements for electric motors 7, 8, which transform the control signals of the track link into switching signals to switch the respective adjustment motor 7, 8. The elements Switching can be, for example, relay switches or / and semiconductor switches. The control elements 12, 13 of the control unit 10, which can be operated manually, generate control signals that are transformed by the transmission unit

9a, 9'a of the control device 9 in control currents for the switching elements. In the control unit 10 ', connected by cable, the control elements 12, 13 switch the control current of the relay switch, or of the semiconductor switch. In both cases, the disconnectors for load shearing of the relay switches, or of the semiconductor switches, switch the high motor current of the respective adjustment motor 7, 8. It is also possible to run in which the currents of the motors circulate directly through the contacts of the control elements 12, 13 of the control unit 10.

The adjustment motors 7, 8 are configured as brushed motors, or have brushes.

For a so-called "memory control" and / or parallel synchronization and / or control controls for several adjustment motors 7, 8, an electromotive force opposite to the respective motor of an adjustment drive 7, 8 is recorded, an evaluation taking place of the so-called "ripples" of the opposite electromotive force. A procedure for this is described in detail in document DE 10 2009 059 267 A1, to which reference is made.

For the uptake of the counter electromotive force of the motor M1 a voltage is measured, which decays into a resistance in the motor conductor, due to the current of the motor that circulates through it during the operation of the motor, in the connections of resistance.

A synchronized control of adjustment drives comprises at least two adjustment drives of an electromotive drive 100 of a piece of furniture, with a joint control installation 9. For example, for the height adjustment of a tabletop with two adjustment drives, both are connected simultaneously. In this, the synchronized control serves so that the two adjustment drives have the same adjustment speed, so that an inclined position of the table does not take place. If the motor of one of the adjustment drives has, for example, a lower turning speed, due to a higher load than that of the motor of the other adjusting drive, then the faster rotation speed of the motor is normally reduced by appropriate measures. of the joint control installation 9. This reduces, for example, the faster engine speed by modulating the pulse width.

Unlike in a synchronized control, a parallel control is now explained, in relation to Figure 3.

Figure 3 shows, by way of example, a schematic perspective view of an arrangement of furniture 200, with two adjacent furniture 1, 1 ', which are configured as a bed, according to Figure 1.

The furniture arrangement 200 comprises at least two furniture 1 and 1 '. Furniture 1, 1 'are configured identically. They can also be executed as a double bed. The furniture 1 located on the left in Figure 3 presents an electromotive drive 100 of furniture, with two adjustment drives 7, 8 and a control installation 9. In the same way, the furniture 1 'to the right is equipped with an electromotive drive 100' of furniture, with two adjustment drives 7 ', 8' and a control installation 9 '. The two electromotive drives 100, 100 'of furniture are normally equipped with a control unit 10. However, here only one control unit 10 is provided, with which the two electromotive drives 100, 100 'of furniture can be operated. The other control unit is not necessary.

For this, a parallel control of at least two adjustment drives 7, 7 'is provided. However, the adjustment drives 7, 7 'belong to different electromotive drives of furniture 1, 1'. That is, the first adjustment drive 7 of the first furniture electromotive drive 1 is connected to the control installation 9 of the first furniture electric drive 1, the other adjustment drive 7 'of the second furniture electric drive 1' being connected with the installation 9 'of control of the second electromotive drive 1' of furniture. This configuration is represented in Figures 4, 4a and 4b, and is explained in detail in relation to those figures.

In this example, a parallel control is provided for both the adjustment drives 7, 7 'and also for the adjustment drives 8 and 8', for a respective leg piece 5, 5 'of a piece of furniture 1, 1'. In other words, the adjustment drives 7, 7 ', as well as the adjustment drives 8, 8' can be operated respectively at the same time from a single control unit 10. In this it is necessary that both the two back pieces 4, 4 'as well as the two leg pieces 5, 5' be adjusted respectively with the same speeds, or at least with very similar speeds. For this, for example, in the case of an advanced adjustment drive 7, the adjustment speed, that is, the rotation speed of that motor, is decreased compared to that of the other slower motor of the adjustment drive 7 '.

Figures 4-4b show images of modular diagrams of examples of execution of parallel control arrangements, according to the invention, of electromotive drives 100, 100 'of furniture, with wireless control units 10. Figures 5-5a show images of modular diagrams of examples of execution of parallel control arrangements, according to the invention, of electromotive drives 100, 100 'of furniture, with control units 10' connected by cable.

An adjustment drive 7 is connected to the first control installation 9 through the driver 100a of the drive. In the second control installation 9 'the other adjustment drive 7' is connected through the driver 100'a of the drive.

Figure 4 shows a first example of execution, in which the control unit 10 communicates with the two control installations 9 and 9 '. In this, a wireless link 23 has been placed between the control unit 10 and a transmission unit 9a of the first control installation 9 between the control unit 10 and a transmission unit 9'a of the second installation of control 9 'there is a second wireless link via 23'.

The wireless links of track 23 and 23 'are bi-directional links, the transmission units 9a and 9'a being configured for the transmission and reception of data.

By actuating the control unit 10, control signals are transmitted simultaneously via links 23 and 23 'via to control facilities 9 and 9', in order to connect and disconnect the adjustment drives 7, 7 ' at the same time.

Figure 4a shows a second exemplary embodiment, only a two-way track link 23 being arranged between the control unit 10 and the transmission unit 9a of the first control installation 9. A connection to the second control installation 9 'is provided by a wireless two-way track link 21 between the transmission units 9b and 9b 'of the first control unit 9 and the second control unit 9'.

When the control unit 10 is operated, a control signal is first transmitted, via the link 23, to the transmission unit 9a of the first control installation 9, which then transmits that signal to the adjustment drive 7 connected, and through the transmission unit 9b to the second control installation 9 ', which in turn controls the second adjustment drive 7'.

In the example of execution according to Figure 4b, the link 21 is configured between the control facilities 9 and 9 'with cable connection. Only the first control installation 9 has a wireless transmission unit 9a for communication with the control unit 10.

Figure 5 shows a parallel control arrangement of two electromotive drives 100, 100 'of furniture, with the corresponding control installation 9, 9' and a respective adjustment drive 7, 7 '. The adjustment drives 7, 7 'are connected respectively, as shown in Figure 4-4b, to one of the control installations 9, 9', through a respective driver 100a, 100'a of drive. This connection can be executed in a fixed or plug-in manner, which is not described here in more detail.

The control unit 10 ', with its control conductor 18, is connected to a distribution unit 20. The distribution unit 20 is connected to the first control installation 9 through a first control conductor 19, and through a second control conductor 19 'with the second control installation 9'. All control conductors 18, 19, 19 'can be connected to the distribution unit 20 plug-in, or fixedly wired.

The function of the distribution unit 20 is that each individual cable of the control conductor 18 is connected with a cable of the first control conductor 19, and at the same time with a cable of the second control conductor 19 '. Through this, a parallel control of the adjustment drives 7 and 7 'is possible, so that they can be connected and disconnected simultaneously by the control unit 10'.

The first command conductor 19 configures a first link of track 23, the second command driver 19 'configures a second link of track 23'. The driver 18 is another link via the 23rd set.

In the execution example according to Figure 5a, a track link 21 is provided, connected by cable, between the control facilities 9 and 9 ', the control unit 10' being connected, with its command conductor 18, to the first control installation 9. The control conductor 18 configures a link via track 23 here.

The track links 23a, 23, 23 ', in the form of cable conductors 18, 19, 19', can also be bidirectional track links.

The conductors 18, 19, 19 'of both exemplary embodiments according to Figures 5 and 5a can be both control conductors and power conductors, which conduct motor current.

Each control installation 9, 9 'is equipped, for example, with a microprocessor, or with a microcomputer, and has a control program. All control programs are configured for communication between each other via the links 21, 22 between control facilities 9 and 9 '. This allows an exchange of adjustment parameters (adjustment travel, adjustment angle, motor current, motor voltage) of the electromotive drives 100, 100 'of furniture between sf, whose quantity is not limited to the two drives can take place 100, 100 'of furniture shown in the execution examples.

This exchange of adjustment parameters of the electromotive drives 100, 100 'of furniture can also take place through the control unit 10, 10' as a joint communication center. In this, the control unit 10, 10 'is provided with a corresponding intelligent control, that is, with a microprocessor, or with a microcomputer.

A simple composition is possible, since all control facilities 9, 9 'and all control programs

of each of the electromotive drives 100, 100 'of furniture can be constructed identically. Another piece of furniture 1, 1 'can be added at any time in furniture arrangement 200.

When the two adjustment drives 7, 7 'are connected at the same time, a communication of specific values of the drives between the control facilities 9, 9' takes place, such as motor rotation speed, motor current and motor voltage . These specific values of the drives are recorded with means of detection of the corresponding control facilities 9, 9 '. In this case, a control program can capture an advance of the corresponding connected motor of the adjustment drive 7, 7 '. The advanced engine is then automatically throttled by its corresponding control installation 9, 9 '.

A throttle of a motor takes place through a pulse width modulation control, a reduction in the operating voltage of the corresponding motor, or 2-point regulators (a temporary disconnection), 3-point regulators (intermediate step with heating resistance or other means of limiting voltage and current), or regulators of n points with more than three points.

The recording of the specific values of the drive is carried out with the detection means through the measurement of the motor current through a brown of tension of a resistance in the motor conductor. The number of motor revolutions can take place through incremental emitters of the rotation pulse, or through the counting of the multiplier effect of the opposite electromotive force of the respective motor.

An adjustment position is determined by potentiometers (rotary potentiometers, linear potentiometers) and communication with other electromotive drives 100, 100 'of furniture.

The furniture arrangement 200 according to Figure 3 is constructed by a simple grouping, or by an assembly. The control unit 10 is subjected to an allocation process, in which a so-called "pairing" takes place. In this, the corresponding control elements 12, 13 (figure 2) are assigned to the respective furniture 1, 1 ', or to the respective electromotive drive 100, 100' of furniture.

Each electromotive drive 100, 100 'of furniture has its own address.

■ The address is determined through a random generator, with approx. 24 million possibilities.

■ Preferably, that address is the serial number of the corresponding electromotive drive 100, 100 'of furniture.

■ An automatic address assignment can take place during assembly.

■ An automatic address assignment can also be made at the first start-up.

The control unit 10, 10 'organizes the pairing

■ Electromotive drives 100, 100 'of existing furniture are sought. Then a synchronization takes place with all the electromotive drives 100, 100 'of furniture that have been found (compare with the wireless telephones and the registration in the base station).

■ A distribution of the corresponding electromotive drive 100, 100 'of furniture for the assignment of the push buttons in the control unit 10, 10' takes place through the combination of push buttons of the control unit 10, 10 '.

Figure 6 shows a schematic flow diagram of a method according to the invention for the parallel control of at least two electromotive drives 100, 100 'of furniture of a furniture arrangement 200.

In a first step S1 of the procedure the current adjustment positions of the driven motors of the adjustment drives 7, 7 'controlled in parallel are recorded.

Then, in a second step S2 of the procedure, a communication of the actual positions between the control facilities 9, 9 'takes place, comparing them between each other.

If a difference is detected, that is, if an advanced motor is identified, then, in a third step S3 of the procedure, the motor of that advanced drive is throttled by the corresponding control installation 9, 9 ', or the other motor It is accelerated at a higher turning speed.

In an alternative, in the second step S2 of the procedure the real positions are compared with values to be established previously, for example the values of a table.

Then, in a third step S3 of the process, a throttle of the advanced motor, or an acceleration of the respective backward motor, takes place with the intensity of a previously preset value, for example a value contained in a table.

the framework of the appended claims.

Thus it is imaginable, for example, that in a control unit 10, 10 ', with a certain amount of control elements 12, 13 for a single electromotive drive 100, 100' of furniture, one of the additional elements 15, 16, 17 (see Figure 2) is configured as a push button or switch, and is intended for a switching.

In an alternative, a control unit 10, 10 'with a certain amount of control elements 12, 13, can be used to control all electromotive drives 100, 100' of the furniture.

For the throttling of an advanced engine, it can be momentarily disconnected. Naturally, it is also possible to temporarily connect a resistor interspersed in the conductor, in series with the respective motor. This is possible because that interleaved resistance is, for example, bridged during operation by a switching relay, which is open for throttling.

The travel path information can be obtained through the counting of the multiplier effect of the opposite electromotive force of the respective motor.

It is also possible that reverberation sensors, potentiometers or light barrier emitters are used. Naturally, travel limiters can also be placed in certain positions along the adjustment path, which provide a travel information, or they can be used to correct a value of the adjustment path.

As described at the beginning, the control facilities 9, 9 'of the electromotive drives 100, 100' of furniture have detection means for recording specific values of the drives, such as motor current, motor operating voltage , the speed of rotation of the motor, or the like, of the electric motor of the corresponding adjustment drive (7, 7 '; 8, 8'), at least one, or are connected to them. Specific alternative values of the drives are the adjustment path of a linearly movable drive element of an adjustment drive (7, 7 '; 8, 8'), or the adjustment angle of a rotating or tilting drive element of another adjustment drive that is not described here in more detail.

In addition, an alternative execution provides several control units 10, which control the arrangement 200 of furniture. According to another alternative, at least one adjustment drive 7, 7 '; 8, 8 'may contain a control installation 9, 9', presenting the adjustment drive 7, 7 '; 8, 8 'and control installation 9, 9' a common housing.
