Definitions

  • Article of electrically adjustable furniture such as a table, bed or reclining chair
  • the present invention relates to articles of electrically adjustable furniture such as tables, beds or reclining chair as stated in the preamble of claim 1.
  • the invention is for the sake of convenience based on height-adjustable tables driven by at least one electric motor.
  • Height-adjustable tables equipped with actuators and/or lifting columns driven by electric motors are adjusted by means of an operation panel.
  • the table is constantly connected to a power supply, typically based on a transformer connected to the mains supply.
  • a mains cut-off is used, which is a unit which cuts off the connection to the mains supply when the actuator system is not being operated and when a key on the operation panel is activated automatically reestablishes the connection to the mains supply.
  • WO 9311593 Dietmar Koch discloses a mains cut-off where a relay in the non energized normal state interrupts the connection to the mains supply.
  • the control is supplied by a capacitor with a battery backup, so that the relay initially is activated by the electric charge of the capacitor, alternatively the battery- backup, at which the mains supply is connected for driving the electrical drives, and charging the capacitor to enable a new activation of the mains cut-off relay later on.
  • the disadvantage of this is that the capacitor and the battery over time can be drained to a level where connection of the mains cut-off is impossible.
  • EP 0 792 533 Bl Linak discloses a mains cut-off, which is characteristic in that a capacitor with activation charge automatically by regular brief connection of the mains cut-off remains charged, so that a battery backup is not necessary.
  • the components of the mains cut-off are however relatively expensive and it also has the disadvantage that extra conductors are required in the cable from the mains supply. Further, there is a continuous standby consumption, although rather limited.
  • WO 2004/019463 Linak discloses a further mains cut-off.
  • the voltage which enables operation of the actuator system is provided directly from the mains supply by means of an oscillator circuit.
  • the mains cut-off connects the mains supply for driving the actuator system.
  • more conductors than supply lines are used in the cable between the mains supply plug and the control . Needless to say there is a standby consumption although this is limited.
  • a further mains cut-off is known from WO 2007/107157 Linak.
  • the mains cut-off which only has two conductors in the power supply cable, has two power modes, where the first mode, in which the mains cut-off is active, supplies the unit with a low voltage, and then when the switches of the operation panel are activated switches to another mode, where the mains voltage supply is directly connected.
  • the advantage is an elegant connection to the mains supply, but with the compromise that the cable, when the actuator system is not being operated, is connected to a voltage, although lower, and also that there is a continuous standby consumption.
  • the purpose of the invention is thus to provide a mains cut-off unit, which completely cuts off the mains supply when the actuator system is not being operated and without being connected to the mains supply builds up and preserves a local energy supply with the purpose of being able to connect the mains supply when the actuator system is being operated.
  • the energy storage may thus be used to activate the relay in the mains cut-off when the actuator system is being operated.
  • the energy storage may simply consist of a capacitor, which is directly charged by the solar panel. This embodiment is advantageous as a capacitor is not critical as to the size of the charging current and voltage. This means that the charge of the capacitor is built up and preserved when the actuator system is not being operated.
  • the capacitor is momentarily charged when the actuator system is operated and the mains cutoff connects the mains supply, so that it is immediately prepared for another operation of the actuator system with release of the relay in the mains cut-off.
  • This is expedient when using a solar panel with a limited effect output, where a complete charging of the capacitor by means of the solar panel will take a relatively long time, for which reason more successive operations of the actuator system could be problematic.
  • the charge of the capacitor will thus only have to be exactly sufficient to activate the relay in the mains cut-off so that the control is supplied from the mains supply.
  • the solar panel in principle will not have to be able to produce more power than what corresponds to the leak current in the capacitor, so that the charge thereof is constantly kept intact.
  • the energy storage is a rechargeable battery. It is characteristic of a battery that is has a high capacity, so that over time the solar panel can build up a relatively high charge, which can release the relay in the mains cut-off several times.
  • An expedient embodiment is achieved by combining the two solutions so that the solar panel is connected to a battery. From the battery a connection is led via a diode to a capacitor. This means that the capacitor has a battery backup in case it should be drained, e.g. over time without operation of the actuator system. If the actuator system is operated, the capacitor will as described above be recharged and thus be ready for another operation of the actuator system with release of the relay in the mains cut-off.
  • the diode located in the blocking direction of the polarity of the power supply will prevent the battery from being charged by the power supply when the actuator system is being operated, for which reason the problems concerning current and voltage limiting in connection with charging the battery are disregarded. The only charging of the battery is conducted by means of the solar panel .
  • the advantage of this embodiment is that a drained battery will not influence the actuator system as long as the capacitor is charged. Due to the diode, it is permitted that the voltage of the capacitor exceeds the voltage of the battery. As the capacitor, which preferably is of the low leakage type, can keep its charge intact over a long period of time, it is permitted that the solar panel over time builds up the charge of the battery without preventing the operation of the actuator system.
  • the relay is equipped with an optocoupler, which galvanically separates the relay from the energy storage, is also achieved that the energy being delivered from the energy storage for cutting-in the mains supply is minimized in that it is only the diode in the optocoupler and not the coil in the relay which should be supplied with energy directly from the energy storage.
  • the diode in the optocoupler may thus be supplied with current from the energy storage directly through a key in the operation panel or from the energy storage through the control in case the operation device is connected to the control .
  • the energy storage is furnished so that it can also supply extra equipment with current, in this case a wireless receiver, which receives a signal from a remote control concerning activation of the actuator system.
  • a wireless receiver may e.g. be an infrared receiver or a radio based receiver.
  • the receiver may be connected to the control in the control box or be integrated directly into the control.
  • the extra equipment is expediently optimized to minimum power consumption, so that the size of the solar panel may be reduced. This particularly applies in the stand-by state, where the actuator system is not being operated.
  • the light level may vary owing to the cycle of the day and year. This could e.g. mean that the charged energy of the battery is increased in the daytime and decreased over night. If the battery is drained, the capacitor will still have enough energy to activate the mains cut-off.
  • the challenge is more that the extra equipment, in the form of the receiver, is not supplied with power, for which reason a signal concerning adjustment of the actuator system cannot be received.
  • a further embodiment of the invention thus has means for measuring the state of charge of the batteries and a control, which automatically connects a charger for charging the battery from the mains supply. Thus it is ensured that the receiver is constantly functional.
  • the energy storage is supplied with energy via the control when the mains cut-off has connected the control to the mains supply.
  • the control has means for externally controlling the mains cut-off to keep the mains supply cut in without activating a key on an operation panel, that being a fixedly mounted operation panel or a wireless remote control.
  • the optocoupler is supplied from the control.
  • the energy can thus be supplied from the energy storage when the mains cut-off should be cut in or directly from the control when this is supplied from the mains supply and it is necessary to externally control the mains cut-off to keep the supply cut in.
  • the article of furniture with the mains cut-off is stored for a long period of time under conditions where the solar panel is not exposed to light, e.g. in a cellar or in a warehouse where the light is turned off, and the mains cut-off is not connected to the mains supply, it cannot be avoided that both the capacitor and the battery over time is drained to a level where the receiver is not active and the relay in the mains cut-off cannot be activated.
  • the mains cut-off may expediently be equipped with a device which, when the mains cut-off is connected, briefly supplies the control with power, at which the control may perform a test of the state of the energy storage and then force the mains cut-off to stay connected to the mains supply for as long as it is needed to recharge the battery.
  • This device may incidentally also be implemented in the previously mentioned embodiment of the invention, which comprises a battery as energy storage, so that it is both ensured that the capacitor is always supplied with sufficient power to release the relay in the mains cut-off and that possible extra equipment is always supplied either from the mains supply or from a battery.
  • the solar panel which is part of the invention may be of the known type which is e.g. used in calculators.
  • Solar panels are often designed as one module with ready-made cables so that the solar panel is ready to be connected to the apparatus .
  • the module with its housing may be inserted into the table top so that it does not take up space.
  • DPT Desk Panel Touch
  • Linak A/S which is an operation panel.
  • a solar panel may likewise be build into such a housing for insertion into a table top.
  • Other locations may however be anticipated, e.g. in that the solar panel is mounted under the table top, but with the solar panel facing in a direction towards a light source or a window through which the sun light shines .
  • the overlying layers of laminate will have to be crystal-clear, but they can be stained and still be penetrable to wavelengths of lights received by the solar cells.
  • the pattern in which the solar cells are printed also makes it possible to add decorative elements to the table top.
  • the solar cells may be printed in a shape and with color which depicts a graphical figure, e.g. a profusion of flowers, an electronic circuit, text or numbers.
  • a graphical figure e.g. a profusion of flowers, an electronic circuit, text or numbers.
  • the purpose is however still that the solar cells produce power which can be transferred to an energy storage. The effect of the charging will naturally be largest when the desk is cleared, but even a small contribution is appreciated.
  • a group could e.g. constitute an icon which indicates a certain function which can be activated.
  • an adjustable table is could be a virtual switch for operating functions in connection with the adjustment of the table or other units, which may be turned on or off.

  • the table shown in Fig. 1 comprises a table top 1, which at each side is carried by two identical lifting columns 2,3 of the type shown in WO 03/003876 Al Linak A/S.
  • the lower end of the lifting columns is mounted with a foot 4.
  • the control box 5 is with a mains cable connected to the mains supply.
  • a circuit for cutting off the mains, a so-called mains cut-off may be located in connection with a plug on the mains cable or be located in the control box 5.
  • An operation panel 6, connected to the control, is equipped with keys 7 by means of which it is possible to adjust the height of the table top.
  • a solar panel 8 is inserted into the table top. It is noted that the solar panel is positioned near the edge so that it under normal circumstances is not covered by paper or other objects.
  • Fig. 2 is a diagram, showing the function of a mains cutoff.
  • the mains cut-off consists of a relay 9, which must be energized in order to cut in the mains supply when adjusting the height of the lifting columns 2,3. It is understood that the mains cut-off, when the table is not being operated, is in the standby position, where the relay 9 is not energized.
  • the control box 5 is thus cut off from the mains supply in that the relay 9 interrupts both conductors at the terminals 10.
  • the relay is supplied with current via the diode 11 when the transistor 12 is active.
  • the transistor 12 is an electronic switch, which either is controlled completely on or is completely off and in the preferred embodiment is part of an optocoupler, which also includes a light emitting diode 13.
  • the transistor 12 When the diode 13 is supplied with current, the transistor 12 is activated and draws current through the coil in the relay 9, which thus connects the mains supply to the control box 5 and thus also to the lifting columns 2,3.
  • the diode 13 is supplied with current from an energy storage 14 when the key 7 is operated.
  • the supply of the control box 5 thus depends on that the energy storage 14 contains sufficient energy to supply the diode 13 with energy when the key 7 is operated.
  • the energy storage 14 may, as shown in Fig. 3, be designed as a capacitor 15.
  • the energy storage 14 is supplied with energy from the solar panel 8. It is noted that the capacitor is briefly charged from the control box 5 when this is supplied from the mains supply, as the effect of the solar panel is not sufficient to charge the capacitor 15 so that multiple operations can be performed successively. The charge of the capacitor 15 need therefore only be exactly sufficient to activate the relay 9 in the mains cut-off, so that the control box 5 is subsequently supplied from the mains supply. This further means that the solar panel 8 in principle will not have to be able to supply more effect than what corresponds to the leak current in the capacitor 15, so that the charge thereof is constantly kept intact.
  • the solar panel 8 only supplies effect when it is exposed to light, it should be expected that the effect varies owing to the cycle of the day and the year, for which reason the size of the solar panel should be adapted so that it on a long-term basis can supply the necessary effect to compensate for the leak current of the capacitor 15.
  • Fig. 4 shows another embodiment, where the energy storage 14 is a rechargeable battery 16.
  • the energy storage 14 is a rechargeable battery 16.
  • a rechargeable battery makes demands on charging voltage and maximum charging current, and should therefore be equipped with a charging circuit 17, which ensures that these demands are met.
  • a further complication is that it should be possible to charge the batteries both from the solar panel 8 and the control box 5, where the supplied effects should be expected to be of very different sizes.
  • the design of the charging circuit 17 is thus practically a switch-mode regulation, particularly due to its ability to minimize the loss when transferring energy at varying energy rates.
  • a switch- mode charging circuit can be described as a circuit, which converts a charge with a given potential into a charge with a different potential, so that this charge e.g. has a suitable potential to be absorbed by an energy storage.
  • the circuit does not contain a capacitor in the energy storage, the energy, which runs through the diode 13 in the optocoupler for releasing the relay 9 in connection with an activation of the key 7 on the operation panel 6, should be taken from the rechargeable battery, as the contribution from the solar panel 8 cannot be expected to be able to fully supply the necessary effect.
  • the energy storage 14, designed as the rechargeable battery 16 supplies its energy through the diode 18, which is located parallel to the charging circuit 17.
  • Fig. 5 shows a combination of the two embodiments shown in Figs . 3 and 4 where the energy storage 14 now both consists of a capacitor 15 and a rechargeable battery 16.
  • the solar panel 8 builds up and preserves a charge on the rechargeable battery 16, where the rechargeable battery serves as a battery backup for the capacitor 15, so that the voltage thereon is always preserved to be at least 0,7 volt (a diode energizing) lower than the recharged battery voltage.
  • the diode 19 only allows the current to run from the rechargeable battery 16 to the capacitor 15 but not the other way. This means that the control box 5 cannot charge the battery 16 when the control in the control box 5 during activation of a key 7 on the operation panel 6 is active, but briefly can charge the capacitor 15.
  • the voltage over the capacitor 15 may thus be higher than the voltage on the rechargeable battery 16. If the table 1 is not operated for at long period of time, so that the capacitor 15 is drained, the voltage over the capacitor 15 will be preserved by the rechargeable battery 16, which continuously has its charge preserved by the solar panel 8. This means that the table can always be operated.
  • This construction further has the advantage that the charging circuit 20 for the rechargeable battery 16 may be kept simple and be directed to that the rechargeable battery 16 is only supplied from the solar panel 8.
  • the energy storage 14 is designed in such a way that it is also able to supply extra equipment 21 in the form of a wireless receiver with energy.
  • the wireless receiver 21 has a continuous energy consumption in order to monitor if a signal for activation of the lifting columns 2,3, is sent from a wireless remote control .
  • the solar panel 8 for preserving the energy storage 14 is thus designed to, over the cycle of the day, be able to supply energy, which corresponds to this permanent current and the possible leak current in the energy storage 14. That the table may be operated from a wireless remote control thus depends on that the extra equipment in the form of a wireless receiver 21 is supplied with current from the energy storage 14.
  • the activation of the diode 13 in the optocoupler for cutting in the mains supply during operation is now controlled by the control box 5 and activated by the wireless receiver 21 connected to the control box 5.
  • the connection between the wireless receiver 21 and the control box 5 supplies, as shown, the wireless receiver 21 with energy and exchanges data between the two units.
  • the control box 5 should therefore also be supplied from the energy storage 14.
  • the solar panel 8 supplies enough energy to the energy storage 14 through the charging circuit 22, this does not constitute a problem, but in case this supply for some reason is cut off or limited, the energy storage 14 will occasionally have to be supplied from the mains supply through the control box 5.
  • control box 5 By furnishing the control box 5 with a connection 24 which is used both for measuring the battery voltage and for draining off energy from the energy storage 14 along with a further connection 25 used for transferring energy to the energy storage 14, this is made possible.
  • the transference of energy to the energy storage 14 is initiated when the control box measures that the voltage of the energy storage is drained to below a predetermined threshold voltage.
  • control box 5 should be equipped with means for keeping the mains cut-off cut in during this process. When storing the table for a long period of time in light-deficient surroundings e.g. a cellar, and without it being connected to the mains supply, it cannot be avoided that the energy storage 14 over time is drained completely so that it is not possible to operate the table.
  • the mains cut-off When the mains cut-off is connected to the mains supply, it briefly cuts in the supply for the control box 5 in order to measure the state of the energy storage 14 and in case of a low voltage level keep the mains supply connected and initiate a recharging of the energy storage 14 irrespective of whether or not the solar panel 8 transfers energy. In this way the energy storage 14 may be built up to a level, where the solar panel 8 again can preserve the capacity of the energy storage. Thus is overall ensured that the operation of the lifting columns 2,3 is possible in that the wireless receiver 21 is always supplied with energy and that the mains supply is cut off from the control box 5 when this is possible. The time period where the mains supply is cut off is increased in that a solar panel 8 preserves and builds up the electrical energy in the energy storage 14.
  • an energy storage 14 with a rechargeable battery 16 and charging circuit 22, 23 belong thereto, but the energy storage 14 could also be a capacitor, e.g. a so-called supercap.
