Definitions

  • the invention relates to a device for adjusting a according to the pivoting section of a piece of seating or reclining furniture the preamble of claim 1.
  • Such devices are in the furniture industry has long been known and in use to provide various Sections of seating or reclining furniture are preferred to be able to adjust by motor.
  • the use of articulated gears has the advantage that the movements are exactly the individual Ratios can be adjusted and that depending on the used drive element reductions or translations possible are.
  • An adjustment device using flat Joint drive is, for example, by EP A 315 588 known.
  • a disadvantage of known devices is in part insufficient stability of the overall system.
  • be individual gear parts and individual sections of the seat or Lounger furniture is exposed to strong mechanical loads.
  • the ground clearance under the seat or lying surface to be adjusted is sometimes not optimal. It is therefore a task the invention, a device of the type mentioned create a maximum of security with simple construction and stability guaranteed, and in which no mechanical Overloads occur.
  • the device should especially suitable for the drive by electric motors.
  • this object is achieved with a device which has the features in claim 1.
  • the two The rocker arm and the two coupling levers obviously form a quaternary flat gear link with four swivel elements.
  • the scissor-like opening and closing of the coupling lever causes an enlargement or reduction via the thrust joint the distance between the free ends of the coupling levers, what in a simple way for the adjustment of a pivotable section can be exploited.
  • One of the coupling levers on the coupling lever joint is particularly advantageous articulated with a limited lead, whereby when the drive element is actuated, only the neighboring one Coupling lever can be swung open.
  • the second coupling lever remains over the entire distance of the preliminary run first in his Rest position, which slows the overall lifting movement. This has the advantage that the acceleration from a neutral rest position is not too big, because this is perceived as uncomfortable becomes. Only after the lead has been completed will the second coupling lever is gripped by the pushing movement and starts with the swing-up movement.
  • the frame for the rocker arm joint can be the end section of a Be housing that surrounds the drive element and the openings for the coupling lever.
  • the drive element for the Coupling lever preferably has a screw nut that can be actuated via a threaded spindle.
  • the threaded spindle can be particularly easily attached to the housing Drive the electric motor. For generating a push movement the use of pressure cylinders would also be conceivable.
  • a particularly advantageous modular design can be achieved if two articulated gears so together to form a gear unit be connected that the sliding joints on a common Axis lie and that the coupling lever of the two articulated gears can be swung open on a common level and in opposite directions are.
  • Such a gear unit can be moved across install in a bed frame, with different widths can be taken into account by different housing lengths. In this way, the assembly effort can be great to reduce.
  • Both articulated gears can have a common one Drive motor are operated.
  • the articulated gear can also be driven by a traction mechanism.
  • a traction mechanism e.g. Threaded spindles, racks or push rods
  • a cable pull which has a Rope drum is drivable. The advantage of the cable pull is that Devices for different bed widths are practically only differ by different housing lengths, while at sufficient rope supply for every width the same cable pull can be installed.
  • the gear unit is used on a bed such that the plane of movement of the coupling lever is at right angles run to the long sides of the frame of a bed.
  • the end a coupling lever of at least one articulated gear is present on the frame and the end of the other coupling lever on the swivel Section hinged.
  • the force is applied completely symmetrically and there are only slight reaction forces that act on the Act frame.
  • the ground clearance under the bed is very good large because the gear unit only has a low overall height having.
  • a gear unit 15 consists two articulated gears 1, 1 ', which have a common electric motor 14 can be actuated.
  • the connection of the two articulated gears takes place via a housing 10, which is simultaneously the linear Guide for each sliding joint 8 or the threaded spindle 13 surrounds.
  • the threaded spindles for the two articulated gears are in place in operative connection with the drive motor via a gear part 21.
  • the two end portions 11 of the housing are opposite to each other Pages provided with openings 12 from which the pairs of levers of the articulated gear protrude.
  • the two end faces of the housing at the same time form the frame 4 for the common Rocker arm joint 3 of the two rocker arms 5, 5 '.
  • Figure 4 shows the starting position with the smallest distance between the frame joint 24 and the Lying surface joint 25. Moved by turning the threaded spindle 13 the sliding joint 8 in the illustration to the right against the Rocker arm joint 3. Initially only the upper coupling lever 6 swung out, while the lower coupling lever 6 'due the lead in the coupling joint 7 in its original Position remains. If the lead is completely covered, that is Position reached according to Figure 5. From this position too the coupling lever 6 'swung out, which accelerates the lifting movement.
  • Figure 6 shows the articulated gear with the maximum possible distance between frame joint 24 and lying surface joint 25th
  • FIG. 7 shows the practical application of a gear unit 15 according to Figures 1 and 2.
  • a bed 16 with a slatted frame 20 has a back part 15 and a foot part 18. Back part and the foot part are pivoted on a frame 19.
  • a gear unit is used to adjust the height of both parts 15 or 15 'used, these gear units transversely to be mounted to the longitudinal direction of the frame 19.
  • the housing 10 also rises and falls with the Drive motor 14, namely by about half of the total stroke.
  • the overall installation height of a gear unit is very low, which leads to good ground clearance.
  • a traction mechanism serves in the Shape of a cable 26.
  • This cable is at a point of attachment 29 attached to the frame and looping around the coupling lever joint 7 and the rocker arm joint 3.
  • the rope supply is wound on the cable drum 27, which is via the electric motor 14 is drivable.
  • a return spring 28 ensures that with the cable pulled, the coupling levers 6, 6 'into the closed position are biased.
  • the cable could also interact with the articulated gear in a different way, e.g. at another attachment point, via additional pulleys etc.
  • the device according to the invention could also still be used in other ways. So in particular should the installation of an articulated gearbox is not necessarily transverse to the swivel plane of the section to be adjusted.
  • a single link mechanism could drive a section or independent articulated gears with individual, synchronized drive motors are used. In In certain cases, the drive could also be used instead of a motor done manually. Pressure medium cylinders, Racks or hollow shaft gear can be used.
