Definitions

  • the invention relates to a piece of furniture with at least one relative to a fixed component by means of several actuators each equipped with a drive motor actuators in certain nominal positions during the adjustment adjustable component, and in which each actuator at the same time by means of a control unit or a manual switch can be controlled.
  • the furniture in question are in particular sitting and lying furniture, such as beds or armchairs. It is required that the adjustable component or the adjustable components always perform a uniform movement. Since in particular beds are used in the hospital or in the care sector, it must be ensured that the predetermined desired positions are maintained during the adjustment. According to a relevant provision, it is provided that after a certain number of adjustment cycles, for example 10 cycles, the maximum angle adjustment is relatively small, for example 2 °.
  • DC motors are used for the actuators, which are operated with a safety voltage of 24 or 42 volts.
  • the known furniture such as beds
  • the mattress frame is loaded unevenly over its length.
  • parallel-connected direct current motors cause different adjustment speeds for different loads, that is, the higher the load, the lower the adjustment speed.
  • the drive motors of the adjustment drives are controlled by a synchronous control.
  • the actual position of the output member of each actuator is permanently monitored and at a non-uniform running of the actuator drives, that is, at different output speeds of the output members engages a control unit regulating in the adjustment, so that a uniform movement of all actuators is given.
  • These known synchronous controllers work together with incremental or absolute encoders of the actuator.
  • the actuators for furniture should be extremely inexpensive to manufacture. Therefore, such synchronous controls are not applicable.
  • Such synchronous controls are preferably used in machinery and equipment, but they are not to be regarded as mass products and are not comparable in price. Simple systems are therefore used which, however, do not ensure that the preset nominal positions are maintained during the adjustment process.
  • these actuators are structurally complex, since the encoders are integrated into the actuators. The known synchronous controls are therefore not applicable for furniture.
  • the invention has for its object to design a piece of furniture of the kind described in more detail so that the actuators structurally simple and Thus, it is cost-effective that the usual in the furniture sector actuators are used, but that it is ensured that the adjustment of the component to be adjusted or the adjustment of the components to be adjusted in the respective nominal positions can be performed to the fixed component, wherein the target Positions within certain tolerances may be.
  • the object is achieved in a tuned to the number of actuators number of actuators control technology so assigned signalers that in the desired position of each component to be adjusted relative to the fixed component all the signal generator can be controlled simultaneously and that in a deviation from the target -Stellungd regulatory or control technology in the operation of the associated actuator or the actuators is engageable.
  • the signal generators assigned to one actuator or the plurality of actuators will generate a control signal which is either for switching off, preferably for a short time, the actuator or the actuator Actuator leads, and indeed until such time that either the remaining signal generator or predetermined signal generator are driven by the component to be adjusted, which is interpreted as a signal that the desired position is reached.
  • the previously stopped actuators can then be put back into operation.
  • the signal generator triggering a control signal cause the actuators to be actuated to remain in operation at a reduced output speed of the output members. This speed reduction could occur over a given period of time.
  • the first-triggered signal generator or the signal generator the actuating drive or actuators associated therewith to actuation the other signal generator or the other signal generator stops or that the actuator or the actuators are operated at a reduced output speed of the output members.
  • the signal generator are designed as limit switches. It is quite possible that two actuators are controlled by means of a signal transmitter or a limit switch, since, for example, in the height adjustment of a mattress frame of a bed in the head and foot part two actuators are arranged and one can assume that the burden of these two actuators always consistent.
  • the end position of the component to be adjusted or the end positions of the components to be adjusted are also limited in a known manner via limit switches. It is therefore provided to avoid a variety of parts that the trained as a limit switch signal encoders are constructed identical to the end positions limiting limit switches.
  • the signalers can be installed at a suitable location.
  • the signal transmitter or the limit switches are integrated in each associated actuator. This would be the simplest way, because otherwise no other components are required. However, it is also possible that the signal transmitter or the signal transmitter are installed on the respectively to be adjusted component. It would then be appropriate to use appropriate actuators. This can be structurally particularly simple to perform when the signal generator or the signal generator are arranged outside the range of movement of each component to be adjusted, and that are mounted on the component to be adjusted actuators. This version has the advantage that the signal generator are particularly accessible.
  • the signal generators are installed so that they can be actuated upon reaching the central region of the adjustment path.
  • a plurality of an actuator or multiple actuators associated signal generator are arranged one behind the other in the direction of movement of the output member and the output members.
  • the signal transmitters are then interconnected in circuit so that, based on the direction of movement of the output member of the actuator or the actuators, equidistantly arranged, group-linked units form. This prevents that a control signal is triggered only when the actuated in the desired position of the component to be adjusted at the same time controlled signal generator are offset in time.
  • each motor of an actuator should be a low voltage DC motor.
  • two actuators are used to adjust a component, but in case of need, the number can also be increased.
  • the auto switches should be installed in the areas where the most frequent adjustments occur.
  • each actuator should be done in a preferred embodiment by a relay control, since such controls are inexpensive and reliable. Alternatively, however, it is also possible to use a semiconductor control or to switch the motor current directly from the signal transmitter and / or from the manual switch. Furthermore, it would be possible for each signal generator to transmit a control signal to a control unit. Further, it is possible that the motor current is turned on and off respectively, or that the power supply is reduced.
  • the signalers could also be referred to as monitoring switches.
  • the bed 10 is shown only schematically in Figures 1 and 2.
  • the bed 10 is equipped with wheels 15, since it can be used, inter alia, in the hospital or nursing home.
  • the bed 10 includes a base frame 11 and a relative to this base frame 11, in the illustrated embodiment, parallel adjustable mattress frame 12.
  • the mattress frame 12 is adjusted by arranged in the end regions drive units 13, 14, which are arranged either individually or in pairs in the end regions.
  • the drive units 13, 14 are well known. In the illustrated embodiment, they are designed as linear drives in the form of individual drives.
  • On the base frame 11 four wheels 15 are arranged.
  • the drive units 13, 14 can be coupled directly to the mattress frame 12 with their output members, for example the lifting tubes.
  • the adjusting device formed from the drive units 13, 14 may also be equipped with fittings.
  • limit switches 16, 17 are mounted on the base frame 11 on the side facing the mattress frame 12, the plungers of which are retractable and extendable. These limit switches 16, 17 limit the lower end position of the mattress frame 12. The upper limit switches are not shown for the sake of simplicity. In the illustrated embodiment, the plunger of the limit switches 16, 17 are facing the mattress frame 12.
  • tabs 18, 19 are fixed in the end regions, which carry in the free end areas signalers in the form of limit switches 20, 21.
  • the tabs 18, 19 are designed so that the limit switches 20, 21 are located in the middle region of the travel path of the mattress frame 12.
  • the limit switches 20, 21 may be provided on both longitudinal sides of the bed 10 or only on one side.
  • Each limit switch 20, 21 cooperates with switching cam 22, 23, which drive over the Stö- ⁇ el the limit switches 20, 21. As already explained, this normally takes place at the same time, so that the actuating drives 13, 14 are not activated.
  • the invention is not limited to the illustrated embodiment. It is essential that by means of control signals generating signal generator 20, 21, the drive motors of the actuators 13, 14 are controlled.
