Definitions

  • the invention relates to an electrical control switching device for cabinet and / or table furniture mounted on a vertical wall, the positions of which can be changed electromechanically on the wall, such that one or more wall cabinets or tables arranged side by side or one above the other are each between an upper end position and are adjustable in a lower end position and can be locked in any position within the adjustment distance, one or more wall cabinets arranged at the same height and / or one or more tables below the wall cabinets each being arranged at the same height, each with a known tubular shaft with a non-rotatable therein arranged from a usual Mains power line-fed drive motor are non-positively connected and the drive motor is equipped in a manner known per se with an automatic switch-off device for the upper and the lower end position of the adjusting device.
  • Such a control switching device is structurally very simple.
  • the person using the furniture presses the button switch responsible for a certain movement - upwards or downwards - of a furniture part or a row of furniture until the furniture part or the row of furniture is in the desired position, where it remains when the button is released.
  • the invention is therefore based on the object of providing an electrical control switching device for furniture of the type defined in the preamble of claim 1 and at the outset of the description, in which the above-described deficiencies of the known control switching devices are eliminated.
  • the dangers for persons handling the furniture should be excluded, which in themselves are based on a manually operated switching device to which the mains voltage of 220 V is directly applied. In particular, it should also be excluded that incorrect operation can result in injuries to people or material damage.
  • the operating elements of the control switching device should be absolutely currentless in the idle state.
  • the control switching device should be simple and inexpensive to manufacture.
  • control switching device has the features in the form of modules according to the characterizing part of claim 1.
  • a ballast (Fig. 1) with a transformer 1 can be connected with the primary side of the transformer to a 220 V AC power line.
  • a power switch 3 is provided in the connection part 2.
  • a fuse 4 is installed in phase 2a of the power line.
  • Phase 2a and neutral conductor 2b of the mains cable are connected by a cable bridge to a control lamp 5 which indicates the operational readiness of the ballast.
  • the transformer 1 transforms the 220 V mains current into a 15 V low current.
  • a bridge rectifier 6 in the form of a Graetz circuit is connected to its secondary side, through which the 15 V alternating current is rectified into a switching current.
  • an Ic 7 is arranged as a voltage stabilizer.
  • a filter capacitor 8 and an interference suppressor 9 are enclosed before the AND gate 7 and after the AND gate 7.
  • a key switch 10 is arranged in its + phase 6a, with which the downstream operating unit (FIG. 2) can be locked for unauthorized use.
  • a light-emitting diode 11 with a series resistor 12 for current limitation for the light-emitting diode is switched on between + phase 6a and - phase 6b of the switching current line.
  • the signal from the light-emitting diode 11 after the + phase 6a has been connected by the key switch 10 indicates that the operating unit is ready for operation.
  • two pushbuttons 13, 14 are arranged, of which one pushbutton switch 13 is provided for the upward movement of the drive device and the other pushbutton switch 14 for the downward movement of the drive device.
  • a branch 6.1a for the upward movement of the drive device or 6.2a for the downward movement of the drive device leads to an electronic intermediate part of each pushbutton switch 13, 14 - but spatially separated from it - (FIG. 3).
  • a line cross 15 Between the two pushbuttons 13, 14 there is a line cross 15, one leg 15a of which, when the pushbutton switch 13 is actuated, forms a connection between the + phase 6a of the switching current line to the branch 6.1a for the upward movement of the drive device and the other leg 15b of which is actuated Pushbutton switch 14 forms a connection of the + phase 6a to the other branch 6.2a for the downward movement of the drive device.
  • the line cross 15 precludes the switching current being applied to both branches 6.1a and 6.2a of the + phase 6a by simultaneously pressing both pushbuttons 13, 14. It is rather the case that both when both pushbuttons 13, 14 are not pressed and when both pushbuttons are pressed, the following parts of the control switching device are completely currentless.
  • An AND gate 16 is arranged in the electronic intermediate part (FIG. 3) in the branch 6.2a of the + phase 6a of the switching current line intended for the downward movement of the drive device. This only generates a signal on its output side 16a if a signal is present at its two inputs - the branch 6.2a of the switching current line and the input 16b, which is connected to a safety shutdown device arranged on the moving furniture part (FIG. 5) .
  • a transistor 17, 18 is arranged at the ends of the branches 6.1a and 6.2a of the switching current line.
  • Two resistors 19, 20 and 21, 22 are arranged in front of these transistors in each branch 6.1a, 6.2a of the switching current line, of which one resistor 19 or 21 is applied to the phase.
  • the resistor pairs 19, 20 and 21, 22 each form a voltage divider, among other things for voltage limitation at the base of the downstream transistors 17, 18.
  • the electronic intermediate part (FIG. 3) is followed in the control switching device by a control part (FIG. 4), each with a relay 23, 24 at the ends of branches 6.1a and 6.2a of the switching current line.
  • the switching circuit is electrically isolated from the 220 V mains current feeding the drive motor 25 by the relays 23, 24.
  • the transistors 17, 18 function here as switches for the relays 23, 24. Between them and the relays, a diode 26, 27 is arranged in the branches 6.1a and 6.2a of the switching current line, which short-circuit induction voltages coming from the relay coils and thus protect the transistors.
  • a switch 29, 30 is arranged for each relay, from which - spatially separated - a branch 28a, 28b of the phase 28 leads to the drive motor 25.
  • One branch 28a is intended for the upward movement and the other branch 28b for the downward movement of the drive motor 25.
  • a line cross 31 through which the phase 28 of the operating current for the drive motor 25, depending on the action of one or the other relay 23, 24, on the branch 28a for the upward movement or on the branch 28b for the downward movement of the drive motor 25 is passed.
  • phase 28 When the switch 29 is actuated by the relay 23, the phase 28 is directed via the switch 30 and the leg 31a of the line cross 31 to the branch 28a of the phase of the operating current for the upward movement of the drive motor 25. If the switch 29 is actuated by the relay 24, the phase 28 is conducted via the switch 29 and the leg 31b of the cross wire to the branch 28b of the phase for the downward movement of the drive motor 25. In the idle state of the control switching device, phase 28 of the operating current for drive motor 25 is inevitably interrupted.
  • a safety shutdown device (FIG. 5) is arranged on the underside of a hanging cupboard or a hanging cupboard row not shown in the drawing.
  • this is a surface light barrier 32 known per se, the transmitter 32 a and receiver 32 b of which are connected to the switching circuit.
  • the signal transmitter 33 emanating from the receiver 32b is connected to the second input 16b of the AND gate 16 in the electronic intermediate part (FIG. 3).
  • the light barrier 32 detects an object, the light beam is interrupted; the signal running from the receiver 32b via the signal transmitter 33 to the AND gate 16 in the electronic intermediate part (FIG.
  • the invention is not limited to the exemplary embodiment described above with the circuit diagrams shown in the drawing.
  • the operating unit (FIG. 2) can contain an infrared remote control known per se instead of or in addition to the push button switch operation.
  • a corresponding circuit diagram is shown in Fig. 6.
  • a control switching device can also comprise a plurality of pieces of furniture or rows of furniture arranged one above the other, for example a control part for a wall cabinet or wall unit row and a control part for a table furniture or table furniture line arranged below it.
  • the control part for the lower furniture can be designed in exactly the same way as the device described above for a wall cabinet or a row of wall cabinets.
  • the assemblies of the switching device are to be connected so that the safety switch-off device on the underside of the wall cabinet or the wall unit row also comes into effect - in the same way as described above - when an object standing on it moves upwards when the table furniture is moved upwards Area reached. The drive motor of the table furniture is then switched off.
  • a perfection of the control switching device according to the invention is that in the electronic intermediate part (Fig. 3) a switch-on delay is arranged in each switching branch 6.1a, 6.2a, as for example from the circuit diagram according to. Fig. 7 can be seen.
  • a further resistor 20a is first provided in the switching branch 6.2a in the + phases in addition to the resistor 20 in the switching branch 6.1a.
