The adjusting drives 7, 8 can be designed as brush-type DC motors or have them.

FIG. 4 shows a schematic block diagram of an exemplary embodiment of the emergency power supply device 200 according to the invention.

The embodiment shown in Fig. 4 shows the scope of many options with which the emergency power supply device 200 is equipped. The emergency power supply device 200 is a compact, universal unit. It has a housing 210, preferably made of plastic, in which at least one energy store 220 is arranged.

The connection cable 201 has two lines for transmitting power to the emergency power supply of the supply unit 9a of the control device 9 and thus for feeding the electromotive furniture drive 100 and additional consumers, such as lamps, massage units, control units, receivers, etc., on. These two lines are connected by means of the control element 240 with the at least one energy storage 220. For these two lines there is also provided at least one fuse element (not shown), which may be e.g. may be a fuse or a circuit breaker.

Alternatively, at least one of the switching contacts of the operating element 240 is connected to a wire of the connection cable 201 and, when actuated, applies an electrical signal to the said wire, whereby the control device 9 thus detects the actuation.

Furthermore, the connection cable 210 has auxiliary lines, which will be explained in detail below. Some of the auxiliary wires which are the signals of the socket Forwarding 202 to be connected control unit 10 'to the controller 9, are always connected to the contacts of the socket 202.

A possible connection configuration of auxiliary lines and power lines is described in the document DE 298 21 395 U1, to which reference is made here.

The indicator light 222 signals a state of charge of the at least one energy storage 220 and may be connected to the charging unit 221, which has a corresponding output.

The indicator light 223 signals by lighting the presence of mains voltage or operating voltage in the input of the supply unit 9a of the control device. The night light 230, which may also be referred to as a bedside lamp, serves to illuminate a particular area on the furniture 1 for the person using the furniture 1. The particular area may e.g. the floor area be on a bedside. The night light 230 can be turned on and off in different ways. A separate switch may be provided, e.g. on the operating unit 10, 10 'or / and on the emergency power supply device 200. automatically turn on when the electromotive furniture drive 100 is actuated. And it can be turned on by the motion detector 231 and turned off after expiration of a previously adjustable time. The operating element 240 is a button. In one embodiment, when actuated, it connects the at least one energy store 220 to the two power lines of the connection cable 201. In another embodiment, it applies a signal to wires of the connection cable 201. The operating element 241 is also designed as a button, which is used for teaching operating units 10 with control of a wireless transmission path (radio / infrared / ultrasound).

With the control element 242, which is an additional button, a synchronization of various devices can be activated, which will not be described here.

Furthermore, the night light 230 may also be configured as indicator lights 222 and 223, which corresponds to an optical signal output.

The keyboard 243 with the keyboard elements 244 simulates the operating elements 12, 13 of the operating unit 10, 10 'and serves for moving the adjusting drives 7, 8 of the electromotive furniture drive 100 in an emergency operating state, when e.g. the operating unit 10, 10 'should fail.

The USB port 250 is used to connect various devices with a USB connection. He may also have a charge for these devices. The USB port 250 may also be a mini-USB, e.g. additional connection, be executed.

Thus, at the USB port 250, e.g. Batteries are charged by mobile phones. It is also a data exchange possible if the USB port 250 is connected via auxiliary lines through the connecting cable 201 to the controller 9. For example, a connection of a PC / laptop / service device is possible. In this case, the USB port 250 can serve as a data interface looped through the emergency power supply device 200 for data transmission from and to the control device 9. Alternatively, the emergency power supply device 200 may also include a memory device for storing drive-related data. Thus, service data can be read out, control programs and / or control commands can be changed. The Bluetooth device 260 may be e.g. a bluetooth converter and / or a

Wi-Fi converter and / or a Zigbee converter and serves to control the electromotive furniture drive 100 via Bluetooth and / or WLAN and / or Zigbee. A wireless data exchange can also be done this way. In a minimal configuration, the emergency power supply device 200 has only:

The housing 210 with the at least one energy store 220, the connection cable 201, the socket 202, the operating element 240 and the night light 230. The auxiliary lines of the connection cable 201 may be control lines and signal lines, data lines and / or auxiliary power lines. They run between the control device 9 of the electromotive furniture drive 100 and the emergency power supply device 200, as well as freely accessible plug-in connections of the emergency power supply device 200th The control lines and signal lines are used to control motors, lamps or other components of the furniture 1 or / and furniture drive 100, controlling a so-called power-off, and controlling additional functions of the emergency power supply device 200, such as switching on the night light 230.

The data lines are used to connect an external PC / laptop / service device with the electromotive furniture drive 100 or the furniture 1, and for connecting the electromotive furniture drive 100 and the furniture 1 with Intranet / Internet / LAN.

The auxiliary power lines serve to charge the at least one energy storage 220 by a charging circuit (not shown) in the control device 9 when no charging unit 221 is present in the emergency power supply device 200.

All electrical and electronic components of the emergency power supply device 200 may be wired directly or z. be arranged on printed circuit boards. The printed circuit boards can also be flexible printed circuit boards. Of course, other embodiments and combinations are possible, e.g. in the

Housing material embedded conductors.

FIGS. 5 and 5 a show schematic perspective views of the exemplary embodiment of the emergency power supply device 200 according to FIG. 4. The housing 210 of the emergency power supply device 200 is shaped as a kind of envelope housing and here has a bottom wall 214, different longitudinal side walls 215 and 216, a transverse wall 217 and a top wall 218 with two stepped surfaces 218a and 218b. The surface 218a extends along the one longitudinal side wall 215, which is lower than the other longitudinal side wall 216. In the transverse direction at right angles to the longitudinal side wall 215, the surface 218a extends approximately to the middle, then passes in a transverse obliquely upward (approximately at an angle 40 ... 45 °) extending connecting surface 218c, which with one longitudinal side of the other, higher Surface 218b is connected. The other

Longitudinal side wall 216 facing longitudinal side of the higher surface 218a is also connected to the upper edge of the longitudinal side wall 216 via an inclined surface which is inclined downwards at an angle which corresponds approximately to the other angle.

The transverse wall 217 opposite transverse side of the housing 210 is open and forms an access to a compartment 213, which is divided here into two parts and the Energy storage 220, here two 9V batteries or rechargeable batteries. The energy stores 220 are each connected with connection clips 220a (FIG. 5a) to a printed circuit board (not shown) in the interior of the housing 210. The transverse wall 217 of the housing 210 is provided in the region of the higher portion in addition to the higher longitudinal side wall 216 with an opening 217a, through which the sleeve 202 can be reached.

The connection cable 201 is led out of the higher longitudinal side wall 216, wherein a conventional cable gland is used with kink protection.

At the lower corners of the longitudinal side walls 215, a fastening portion 21 1 is integrally formed with a hole for securing the emergency power supply device 200 in the form of a screw-on. Thus, a fastening e.g. done with screws on the furniture 1. Instead of the screw-on tabs and / or plug-in rails can be provided as mounting portions 21 1.

In the lower surface 218 a of the top wall 218 is a resilient Betätigungsla- see 212 formed by a circumferential recess 219. Below this actuating tab 212, the operating element 240 is arranged, which is actuated by the resilient actuating tab 212 when pressed on the actuating tab 212 from the outside. Before that, an opening 219 is made in the area 218a in which the night light 230, e.g. an LED is arranged. The night light 230 is thus located in the immediate vicinity of the operating element 240 and the actuating tab 212 in order to ensure a quick finding of the same. For this purpose, the night light 230 can be switched on automatically by the motion detector 231 or proximity switch, wherein it is electrically supplied by the at least one energy store 220 or a separate energy store.

The connection cable 201 is shown only by way of example, wherein its length may of course be different from the illustrated length.

For the function of the emergency power supply device 200:

The contacts of the socket 202 are completed by the housing 210

looped through and are available at the contacts of the plug 201 a of the connecting cable 201 on. The at least one energy store 220 is completely electrically separated from the two power lines when not in use. at Actuation of the operating element 240, an emergency power supply program is activated in the control device 9, wherein the terminals of the at least one energy storage device 220 are connected to the two power lines. The emergency power supply program of the control device 9, which is executed, for example, in the control block 9d (FIG. 3) by a microprocessor or microcomputer, determines, eg with a voltage measurement, on the two power lines of the connection cable 201 that a voltage caused by the at least one energy store 220 permanently applied and thus starts further sequences of the emergency power supply program.

Alternatively, the emergency power program determines the controller 9 e.g. with a signal monitoring on at least one auxiliary or control line of the connection cable 201, that a keystroke of the operating element 240 was carried out and thus starts more sequences of the emergency power supply program.

The emergency power supply program preferably starts by a single or permanent pressing of the operating element 240, 241, 242. Other programs can be started by repeated coded pressing the operating element 240, 241, 242. Other programs may also be started by pressing a control element 240 or 241 or 242. Another program includes, for example, the so-called pairing between a wireless control unit 10, 10 'and a control device, wherein the radio protocols or the radio frequencies equate to communication over the wireless transmission link. Another other program performs the switching of a voltage output of the control device 9 or the emergency power supply device 200, wherein the voltage output has a low voltage for connecting electrical consumers such as lights. A voltage output of the control device may have a mains voltage.

Then predetermined Versteilantriebe 7, 8 are moved in a predetermined direction of rotation, which causes the associated parts of the furniture 1 are moved to a basic position or in predetermined positions. Once these positions have been reached, further necessary functions are maintained by means of the emergency power supply program, e.g. Messages, warnings, alarms.

The invention is not limited to the embodiments described above. It is modifiable within the scope of the appended claims. For example, it is conceivable that the emergency power supply device 200 has additional auxiliary connections, for example for devices with hollow plugs or the like. At the socket 202 of the emergency power supply device 200, a further emergency power supply device 200 can be connected (and at this also more), since the socket occupancy corresponds to the pin assignment of the plug 201 a of the connection cable 201. Of course, other devices can be connected to it, which are connected to the engine control.

The housing 210 may be, for example, a cut-to-length profile tube, wherein the transverse wall 217 is designed as a stopper. The profile tube has in its interior the compartment 213 and additional grooves in which, for example, printed circuit boards can be inserted, on which the electrical / electronic components are applied, held and wired.
