Definitions

  • the invention relates to an electrically adjustable piece of furniture which has at least one electric drive motor for adjusting at least one furniture adjustment section relative to a furniture support section.
  • Pieces of furniture such as office tables are known which have a height-adjustable table top resting on support feet. Electric motors are integrated into the table feet for motor-assisted height adjustment of the table top.
  • Such a piece of furniture is, for example, in the WO 2010/112574 A2 described.
  • an electrically adjustable piece of furniture with a drive unit for adjusting a furniture adjustment section relative to a furniture support section is known.
  • the piece of furniture has a sensor device for detecting the inclination or the change in inclination of the furniture adjustment section, the drive unit being controllable depending on the inclination or change in inclination. This makes it possible, for example, if the piece of furniture is designed as a height-adjustable table Grasp and press up or down the edge of the table to set a desired height.
  • the US 5,819,669 A discloses an adjustable desk, the table top of which can be adjusted in height relative to the side support feet using an electric drive motor.
  • the drive motor is designed as alternating current, which is powered by mains power.
  • the drive motor is located on a side support base.
  • the US 6,352,037 B1 shows an adjustable table with four side table legs, opposite which the height of the table top is adjustable. There are supports on the underside of the table top that extend telescopically into the table legs. The height of the table top can be adjusted via a common drive motor with a mains connection.
  • One aspect of the invention relates to an electrically adjustable piece of furniture that has one or more electric drive motors which are used to adjust at least one furniture adjustment section relative to a furniture support section of the piece of furniture.
  • the furniture adjustment section can be adjusted at increased speed compared to the furniture support section.
  • the piece of furniture can optionally have a sensor device with which the relative or absolute position or a relative or absolute movement of a furniture section, For example, the relative position or a relative movement of the furniture adjustment section relative to the furniture support section can be detected, wherein the at least one electric drive motor can be controlled depending on the detected position or movement of the furniture section.
  • At least one drive motor in the electrically adjustable piece of furniture are designed as an electric motor that can be operated directly with the mains voltage of the household power network. It is therefore not a drive motor that does not have the necessary electrical insulation to be directly connected to the household power network; Rather, the mains voltage of, for example, 230 V is used directly without galvanic isolation between the household power network and the drive motor and without a transformer that causes galvanic isolation from the household power network. If necessary, the drive motor can be operated using appropriate power electronics with a lower voltage than the household voltage.
  • Galvanic isolation means avoiding electrical conduction between the household power network and the drive motor.
  • the absence of galvanic isolation means that the drive motor is conductively connected or the power electronics of the drive motor is conductively connected to the household power network.
  • the power is no longer limited by a power supply, significantly higher power can be generated in the drive motors, which means For example, larger travel distances and higher travel speeds of the furniture adjustment section can be realized in relation to the furniture support section. It is also possible to adjust the furniture adjustment section via the drive motor with higher loads in shorter periods of time than is possible with low-voltage drive motors that require a power supply for galvanic isolation, the power of which is limited by the power of the power supply.
  • Another advantage of the drive motor(s) is that, in contrast to low-voltage drive motors with galvanic isolation, only relatively small power supplies are required to control the drive motor, which reduces or completely eliminates standby losses.
  • the size of the controller of the drive motor can also be significantly smaller, since with the drive motors used, which do not require galvanic isolation, only the output stages are necessary to control the drive.
  • the cooling capacity is also significantly lower than with low-voltage drive motors, as the controller emits less heat due to its different and smaller design. Due to the lower losses, a higher overall efficiency is achieved.
  • the smaller size of, among other things, the controller makes it possible, for example, to arrange the controller in a space-saving manner, for example in a motor box at the head of a table leg or in a place where the control panels are usually arranged. It is also advantageous that the number of drives that can be connected to a controller can be scaled as desired, as there is no limit to the number Drives through the power supply are no longer available. Due to the lower thermal development, significantly longer switch-on phases of the drive motor can be achieved even under high loads and switch-off phases are no longer required.
  • the piece of furniture advantageously has at least two electric drive motors for adjusting the furniture adjustment section. According to an advantageous embodiment, these can be controlled independently of one another. All drive motors are designed in particular as electric motors that can be operated with mains voltage. It may be appropriate to provide a common controller for the at least two electric drive motors.
  • sensor devices with a gyroscopic sensor and a gravity sensor can be used.
  • the signals from the gyroscopic sensor and the gravity sensor, which outputs an absolute inclination value, are combined.
  • the height of the furniture adjustment section can be determined using an additional distance sensor that measures the distance to the floor, a reference or the ceiling.
  • the independent controllability of the electric drive motors allows a simple structure, in particular in such a way that the different electric drive motors are supplied with different sensor signals. Even in this simplified embodiment, a desired inclination position of the adjustable furniture adjustment section relative to the furniture support section can be maintained.
  • One of the electric drive motors carries out a compensating movement automatically and independently of the other drive motor. An inclination or change in inclination of the furniture adjustment section is detected via the sensor device during the movement of the furniture adjustment section and is compensated for by a corresponding control of the associated electric drive motor.
  • the furniture adjustment section for example a table top
  • two electric drive motors of which a first electric drive motor is controlled in such a way that a desired speed is maintained.
  • the second electric drive motor is controlled via sensor signals in such a way that a desired inclination of the furniture adjustment section is maintained.
  • the sensor signals indicate the current state of the furniture adjustment section at the position and/or speed level.
  • the sensor signals for the first drive motor come from Hall sensors, for example, which determine both the current height and the speed.
  • the drive motor is then controlled in such a way that it maintains a desired speed.
  • the second drive motor does not have one Hall sensor, but is controlled via the signals from a gyro/gravity sensor located on the first drive motor or in the controller so that the furniture adjustment section maintains a desired inclination, for example a table remains straight. If the gyro/gravity sensor is already available for collision detection, no Hall sensors including cables, plugs and evaluation electronics are required for this drive motor and possibly for other drive motors.
  • a version with a so-called master leg is also possible, on which a drive motor that can be operated by the operator is arranged, whereas the other legs are equipped with drive motors, each of which has its own controller and a gyro/gravity sensor and automatically sets a desired inclination of the furniture adjustment section so that, for example, the table remains straight by these drive motors executing the movement required for the desired inclination.
  • exactly one drive motor is used to adjust the height of a table, with the movement of the drive motor being transferable to two table legs via the gear device.
  • the at least one electric drive motor can be switched on and off via an operating unit that is integrated into the housing of the controller, which controls the electric drive motor.
  • the operating unit can, for example, be inserted into the housing of the controller as a prefabricated unit, with the insertion advantageously simultaneously reaching a position in which mechanical contact with switches on a circuit board of the controller is possible.
  • the operating unit has actuation elements such as actuation buttons that are to be operated manually by a user, the actuation elements switching the switches on the circuit board of the controller on or off.
  • the actuating elements are provided with extensions, which are in particular long enough to maintain a sufficient distance of, for example, 6 mm from the circuit board of the controller that is under mains voltage.
  • the housing of the controller and/or the operating unit can be made of a material that allows direct contact with live components.
  • a smaller distance between the actuating elements of the control unit and the bottom can also be used The mains voltage on the controller board must be sufficient.
  • the housing of the controller which is preferably made of plastic, with a relatively high wall thickness to improve stability, for example with a wall thickness of at least 2 mm.
  • the increased stability of the controller housing ensures that the housing is not destroyed under the loads that usually occur, for example in the case of a height-adjustable table, it can withstand loads that would occur if the controller were accidentally hit, for example while lowering the table top onto an object such as a Chair back or the like can occur.
  • the operating unit can, for example, be provided with capacitive control panels that are actuated by the user.
  • the change in capacity when actuated serves as a signal to switch the electric drive motor on or off.
  • the operating unit for switching the drive motor on/off comprises a light source and a phototransistor or the operating unit interacts with a light source and a phototransistor.
  • a light source for example, LED or IR-LED is used as a light source.
  • the light source can be directed towards a control panel of the control unit, with the emitted light For example, a finger is reflected on the control panel, which is registered by the phototransistor.
  • the operating unit in this embodiment is designed to be transparent or at least semi-transparent in order to be light-conducting for the light emitted by the light source.
  • This version has the advantage that the controller in the housing is hermetically sealed to the outside.
  • the LED and the phototransistor are located on the controller board.
  • the operating unit is provided with a display on which a current parameter of the furniture adjustment section is shown, for example the current table height.
  • the operating unit for switching the drive motor on/off includes a radio module for signal transmission to the controller or interacts with such a radio module.
  • the radio module uses, for example, Bluetooth, BLE or WiFi. This version has the advantage that there is no need for an electrical cable, which would have to be electrically isolated for safety reasons. It is operated, for example, via a remote control or a smartphone.
  • the controller has a communication port for configuration, the configuration being carried out via an external device that can be connected to the controller, for example via a connected personal computer. If necessary, an interface element that contains the galvanic isolation can be plugged into the communication port.
  • the controller can be controlled via a PWM signal with one low-side MosFet per direction of rotation, the high side being controlled with one thyristor per direction of rotation and the thyristor in turn via an OptoTriac or Opto Thyristor is controlled. This makes it possible to create a full bridge for the electric drive motor to be controlled with relatively little effort.
  • the drive motor can be advantageous to equip the drive motor with a signal generator for detecting the current number of revolutions.
  • a signal generator for detecting the current number of revolutions.
  • two Hall sensors can be used, which detect a magnetic field that is generated by a magnet arranged on the motor or drive shaft. It is also possible to determine the direction of rotation by using two Hall sensors.
  • a single sensor for example a Hall sensor or a light barrier.
  • the Hall sensor works with one Magnets together, which is advantageously magnetized in such a way that a pole change with a short distance is followed by a pole change with an equally small distance and then a pole change with a long distance. This makes it possible to detect the direction of rotation.
  • a disk on the motor or drive shaft is assigned to it, which has openings of different lengths, for example a longer opening and two shorter openings in the circumferential direction. This also makes it possible to detect the direction of rotation with just one light barrier.
  • the drive motor is equipped with a counter that counts the number of revolutions in the motor, from which the current position and thus the current parameter of the furniture adjustment section, such as the table height, can be determined.
  • the counter must be compared with a reference in order to be able to determine the current parameter from the counted value.
  • the comparison with the reference can, for example, take place during assembly.
  • an interface which communicates with the counter in the drive motor is arranged between the controller and the drive motor.
  • At least two electric drive motors in the same or in different pieces of furniture can be synchronized via the power grid. This makes it possible to carry out synchronization even over longer distances without communication lines.
  • Universal motors, permanent magnet collector motors or brushless direct current motors are used as drive motors that are operated directly with mains voltage, i.e. without galvanic isolation.
