Definitions

  • the invention relates to a furniture drive with at least one electromechanical Drive train and a control unit used to trigger the functions can be controlled by means of an operating element.
  • the furniture drive in question can be used for furniture of all kinds, for example Beds, armchairs, patient lifts and the like can be used. Each depending on the purpose, it is a simple drive with an electromechanical Drive train or a double drive with two electromechanical drive trains.
  • Each drive train contains a drive gear motor, a reduction gear, a rotating drivable spindle, on which as a drive element for a to be adjusted Furniture component a spindle nut is placed.
  • the previously known controls are designed as so-called hand switches.
  • the connection to the control is made by a cable, so that the hand switch depending on the length of the cable in different places in the area of the furniture can be.
  • the hand switch is equipped with several push buttons, whereby for every function a push button is necessary.
  • the number of Push buttons according to the adjustment options of the furniture. Not accidentally two buttons are pressed is a minimum distance between the two buttons possible.
  • the hand switches are not designed so that when triggered one function all other buttons are locked so that it does not result in incorrect operation can come. Incorrect operation would result in the control system failing. To avoid this, the effort is extremely great. So especially at Furniture drives for beds the hand switches are operated in the dark lighting is also necessary so that electricity is constantly being consumed becomes.
  • the controls are designed so that only one motor of the furniture drive can be switched on. However, this is particularly the case with furniture drives disadvantageous, which are equipped with more than one motor, to perform their function must be put into operation at the same time.
  • the invention has for its object a furniture drive closer to the beginning type described so that the control element simplifies construction will and that incorrect operation can be largely excluded and that especially the number of elements necessary to trigger the function is reduced.
  • the task is solved by the control element for triggering several Functions has at least one shift lever such that the respective function can be triggered by the direction of movement of the shift lever.
  • the control element of the furniture drive according to the invention has been omitted to date used push button of the hand switch. Because the shift lever depending on the design is movable in a variety of predetermined directions, is sufficient for the normal furniture drives a gear lever. Since the operator memorizes very quickly, which function is triggered by which direction of movement of the shift lever , it can be operated without looking, so that it can be used even in the dark can be operated without lighting. Since only one function was triggered at a time accidental incorrect operation cannot occur.
  • control element is extremely compact and that it is firmly attached a predetermined point of the furniture can be mounted, for example in the Armrest of an armchair.
  • control element is designed as a control panel and with a switch lever and a push button equipped as an emergency stop device is.
  • the control panel can be optimally adapted to the design of a piece of furniture depending on the type of furniture, either parked at a suitable location or permanently installed become. It when the shift lever is at least two pressure levels is particularly advantageous has, so that thereby the speed of the drive member by a Change in engine speed can be adjusted.
  • a common power source is used to supply the furniture drive can be formed by different sources either individually or in combination.
  • Accumulators, batteries and a transformer come as current sources Rectifier and evaluation capacitor are preferably considered. Then they are different Combinations possible, such as B. an accumulator with a transformer including the charging circuit, an accumulator with an external charger Accumulator with an external charger, which has a minimum output for the Emergency operation supplies and a power supply, which for the supply to the furniture drive plugged in and forms an external charging station in the removed position.
  • the control element of the furniture drive is a control panel 10 formed, which in the illustrated embodiment with a shift lever 11 and a push button 12 is equipped.
  • a shift lever 11 Through the shift lever 11 are preferred Design corresponding to the representations a and b according to FIG. 2
  • a push button with two pressure levels is operated in each direction in order to increase the speed the output member of the furniture drive or the speed of the drive motor to adjust. It is also conceivable to have different pressure levels within of the control lever to accommodate mechanically constructive.
  • stepless control elements such as B. potentiometers, light barriers and the like provided.
  • the gear lever In order to accidentally touch the shift lever To prevent the triggering of a function, the gear lever is a safety gear lever designed that it must first be pressed down and then in a function-triggering Direction can be adjusted.
  • the shift lever 11 is in many versions variable, as shown in Figure 2.
  • the execution a of Figure 2 shows that the shift lever 11 is rotatable about several axes at point M, according to the embodiment b can be moved in several directions, likewise in accordance with version c is rotatable about several axes, but that it is designed as a flat control cross is, while in the execution according to the representation he is also around several axes can be rotated, but is designed as a control disk, in the execution 3 can be moved in several directions, but in contrast to Version b is designed as a flat cross slide and finally according to the Version f designed as a so-called touchscreen with additional evaluation electronics is. In the latter version, it contains pressure-sensitive areas.
  • the options shown under a and b in FIG. 2 are particularly suitable for the design or for the variation for disabled aids.
  • the shift lever 11 carries a ball at its upper free end so that it is cheap can be gripped. In the previously mentioned versions, all necessary Furniture drive functions triggered by a single control become.
  • the push button 12 serves as an emergency switch, for example in the event of a danger to switch off the furniture drive.
  • the shift lever 11 is at the position of the control panel, which has the lowest height.
  • the push button is in the area of the greatest height 12 installed.
  • the transition area is designed as an inclined surface and in In this area there is a display 13, which is generally referred to as a display.
  • the control point 10 can be taken in hand if, for. B. an operator stands next to the furniture in which there is a person to be cared for. In another Design, the control panel z. B. Disabled to be strapped to the arm or by means of a suitable clamping mechanism by disabled people themselves in a simple manner recorded, attached and used.
  • the control for the not shown Furniture drive is in the housing 14, which is purely schematically by the Angle 14 is shown.
  • the connection to the control panel 10 is made by a Multi-core cable 15, which with a plug 16 arranged thereon with an output socket 17 of the controller 14 is connected.
  • the controller can be integrated within the housing of the furniture drive, or in an outside of it arranged chamber may be arranged.
  • the cable 15 is particularly in a spiral version manufactured so that remote positioning enables or facilitates becomes.
  • the control circuit is supplied with power by an accumulator 19 or by a battery. If a Accumulator is used, this can be done using an external charger or constantly charged or recharged by means of an integrated charging circuit in the power supply unit 18 become.
  • the power supply unit 18 is removable and can be used as a charger or as a charger with minimum power for emergency supply as well as a power supply for the whole Serve voltage supply.
  • the power supply 18 is by means of another Cable 20 and a plug 21 to a socket of the network connected.
  • the power supply of the drive motor, not shown, or the drive motors are connected to one or more output sockets 22 of the controller 14.
  • control unit can be wireless in another embodiment Connection to the controller 14 are operated.
  • the coding of the control signals remains for both wired and wireless transmission links equal.
  • the push button 12 is then both on the control of the drive and on the control unit, analogous to a known, wireless crane remote control.
