Definitions

  • the invention relates to an electromotive furniture drive, in particular for seating and / or reclining furniture such as armchairs, beds and slatted frames, according to the preamble of claim 1.
  • Such seating and / or reclining furniture has fixed and movable furniture components.
  • Fixed furniture components are e.g. Frame components.
  • Movable furniture components are e.g. Fixed or resilient support surfaces of an upholstery or a mattress of the seating and / or reclining furniture.
  • the electromotive furniture drive is used to adjust the movable furniture components.
  • the adjustment movement and drive force generated by the electromotive furniture drive are transmitted to the respective movable furniture component, the electromotive furniture drive being supported on a fixed furniture component and the moving furniture component being adjusted relative to the fixed furniture component.
  • the electromotive furniture drive can also be attached between two movable furniture components, whereby it can adjust them relative to one another.
  • a functional fitting couples the movable furniture components with the fixed furniture components and / or the movable furniture components with one another and is coupled to the electromotive furniture drive.
  • the functional fitting can be seen as self-sufficient and as an independent system if a coupling element of the functional fitting is mechanically coupled to the output element of the electromotive furniture drive.
  • the functional fitting can comprise several coupling elements that are connected to one another. Such connections can be designed to be articulated. Other connections are permanent.
  • the functional fitting can therefore also be understood as a lever chain or lever link chain, which can also have hinges.
  • Another coupling element of the functional fitting is mechanically coupled to a furniture component.
  • the connection can be made fixed. Alternatively, it is designed to be articulated. Other connections are movable or loose force supports.
  • Electromotive furniture drives and functional fittings are known from the prior art in a large number of different designs for different applications and purposes. Electromotive furniture drives are e.g. in use as single drives, double and multiple drives.
  • furniture drives each have a motor, including a downstream gear, for each furniture component to be adjusted, which complicates the structure of the furniture drive and a control device assigned to it, and also makes it more expensive.
  • a furniture drive designed as a double drive is known, with which two furniture components or assemblies can be adjusted with only one electric motor.
  • the furniture drive has two threaded spindles which can be rotated jointly by one electric motor and which have opposite pitch directions of their threads.
  • a respective threaded nut acts on the corresponding furniture component via a pivot lever. Due to different points of application of the threaded nuts on the pivot lever, one of the furniture components can be moved before the other. Any further independent movement of the furniture components is not possible, however.
  • One object of the invention is to provide a furniture drive and a functional fitting of the type mentioned at the outset, in which there are expanded possibilities for the independent movement of the furniture components with only one electric motor.
  • the furniture drive has an electric motor which interacts with at least two spindle lifting threads via a gear wheel to adjust several furniture components.
  • One motor can thus advantageously be used for two or more adjustment functions.
  • the at least two spindle lifting threads each have a threaded spindle with an opposing pitch direction, the threaded spindles and the gear wheel have a common axis of rotation. Different directions of movement are thus possible in a simple manner.
  • a nut is applied to the thread turns of each threaded spindle, each nut being non-rotatable, but designed to be longitudinally displaceable and guided in the housing of the furniture drive, with each nut acting directly or via intermediate links on an adjusting lever or pivot lever, which is coupled to the associated furniture component and / or to a furniture component to be adjusted.
  • a head or back part nut is connected to the furniture component for adjusting the back part, and that a leg part nut is connected to the furniture component of the leg part and / or the foot part.
  • the back part and the leg part and / or the foot part are thus effectively connected to the drive.
  • the back part nut acts directly on the back part of the furniture, and the leg part nut acts on the leg part of the furniture via an intermediate member.
  • the functional connections are thus provided in a simple manner.
  • At least one coupling slide is also provided, which is arranged displaceably mounted between the back part nut and the intermediate member. This results in an advantageous further coupling option for the individual adjustment of the associated furniture parts.
  • the back part nut moves in the direction of the leg part nut, actuates the coupling slide, which transfers the adjustment force generated by the back part nut to the intermediate member, which means that only the leg and foot part is adjusted as a furniture component.
  • the back part nut only actuates the leg and foot parts via the intermediate links consisting of the intermediate link and coupling slide.
  • the coupling slide thus creates an independent adjustment option for one of the furniture components in the second direction of rotation.
  • guide means such as webs or recesses for the displaceable guidance of the at least one coupling slide can be provided in the housing in order to enable easy adjustment.
  • the coupling slide can be made in one piece or in several pieces. Different materials are also possible.
  • Figure 1 shows a schematic perspective view of a first example of a piece of furniture 1 in the form of a bed with a first example of a functional fitting 4 and an electromotive furniture drive 3 in the form of a double drive.

  • These support surfaces are adjustable in such a way that the back part 2b about a back part axis 2f (see Fig. 2 ) and the leg or foot part 2c about a leg part axis 2g (see Fig. 2 ) are pivotable and can assume different positions.
  • Figure 1 shows these support surfaces in an adjusted position, which can be called the reading position, for example.
  • the furniture 1 has a functional fitting 4 and / or the electromotive furniture drive 3, the functional fitting 4 and / or the furniture drive 3 being inserted into the silhouette or contour of the furniture 1 in an inventive manner are.
  • An embodiment according to the following figure descriptions is possible as a functional fitting.
  • a manual remote control for operating the furniture 1 is provided, which in this embodiment e.g. is wirelessly designed as a radio remote control.
  • the handheld remote control and an associated radio receiver and a controller with a power supply are not shown here.
  • a smartphone is designed as a handheld remote control and is connected to the receiver via Bluetooth.
  • the manual remote control can also be designed as a cable manual switch.
  • the cable hand switch can be connected to an associated controller.
  • the switching contacts of the buttons of the manual cable switch are provided for direct switching of the motor current of one or more motors of the furniture drive 3.
  • a motor is provided which can be operated with a low voltage, for example a protective low voltage of less than 30V.
