Definitions

  • the invention relates to a transformable furniture comprising a frame with at least one set up on a foot and a pivotally mounted on the frame pivot module with a plurality of pivotally interconnected pivot segments, said pivot module from a lying position, in which the pivot segments adjacent to each other provided in a plane are and form a substantially horizontal lying surface, can be brought into a sitting position and back, wherein in the sitting position in any case individual pivot segments are compactly compacted and surrounded by the frame and by at least one pivoting segment a seat is formed.
  • Generic transformation furniture are known in a variety of shapes and sizes on the market. Especially in the area of apartments with small living space or in the hotel industry, they are widely used because of their dual function.
  • the transformable furniture on the one hand is a comfortable sleeping furniture for the night and on the other a padded seating, which can be used during the day with almost no functional restriction.
  • Object of the present invention is to provide a transformable furniture with improved carrying capacity and stability.
  • the invention in conjunction with the preamble of claim 1, characterized in that on the frame a support arm is adjustably held, which is provided in the reclining position of the pivot module in a support position and so created from below against at least one pivot segment of the pivot module is that a bending of the bed surface is counteracted, and which is spent in the sitting position disengaged.
  • the particular advantage of the invention is that by providing the support arm, the lying surface provided in the lying position is supported and stiffened. A deflection of the lying surface is thus reduced, with the result that the lying comfort is improved. At the same time counteracted by reducing the deflection of a mechanical load or deflection of the frame and the pivot module on the one hand and the connecting elements on the other hand, which are provided for pivotally fixing the swivel module to the frame. At the same time, it increases the lifespan of the furniture of transformation. Finally, it is counteracted by the reduction of the flexibility of a consequently perceived as unpleasant or disturbing noise, which occurs when received as a result of the use of the transformation furniture mechanical forces or wear components of the transformation furniture deformed or moved relative to each other.
  • the pivoting segments of the pivoting module may be formed in a known manner elastic or yielding.
  • the Swivel segments have an elastically resilient support fabric or a slatted frame.
  • a metal grid may be provided to realize the elasticity.
  • the number of pivot segments of the swivel module use-specific freely selectable for the inventive transformation furniture.
  • four pivot segments can be pivotally connected to each other. Accordingly, in the lying position, the four pivoting segments are provided adjacent to each other in a common plane, whereas in the sitting position the four pivoting segments are at least in part covered by the frame.
  • An outer, first pivot segment forms, for example, the seat.
  • a backrest is formed for example by a further pivot segment or a foot of the pivot module.
  • the support arm can be fixed, for example via hinges pivotally mounted on the frame of the transformation furniture.
  • the support arm can be provided that the support arm is not detachably connected to the frame at the factory.
  • the determination can for example be made cohesively, in particular by welding.
  • the support arm can be held longitudinally displaceable on the frame.
  • the longitudinal displacement can be realized for example via a linear guide or a scissors or toggle mechanism.
  • the support arm is realized as part of a mountable to the frame support module.
  • the support module can be provided by the provision of the support module, a separate unit with the support arm, which can be mounted separately at the factory or in particular subsequently added as a separate module to existing transformation furniture. It is therefore possible, using the support module to offer a retrofit solution for transformation furniture, which are already in large quantities in the market. For example, defects can subsequently be remedied in a customer complaint.
  • the support module has a supporting foot applied against the footprint.
  • forces are directly and directly supported on the footprint with the result that a mechanical load on the frame is reduced.
  • an additional stiffening which leads to an increased sense of comfort and at the same time can reduce the deflection and mechanical stress, for example in the connecting joints.
  • the support arm is applied centrally relative to a width direction from below to the lying surface.
  • this results in addition to the good support effect, a substantially same comfort for lying on both sides of the support arm formed lying surfaces of a double couch.
  • the support arm is applied with respect to a longitudinal direction of the lying surface in a middle section at this same.
  • the middle section is spaced apart by a quarter of a length of the lying surface from a head end of the lying surface and a foot end thereof. So it covers the middle 50 percent of the bed area.
  • the support arm is placed in the support position against a rigid body of the pivot module.

  • the spring load counteracts a joint play, which may possibly be perceived as a quality restriction.
  • a traction means is provided between the support arm on the one hand and the pivot module on the other hand.
  • the traction means serves to pivot the support arm from the support position toward a non-use position in which the support arm is positioned when the pivot module is provided in the sitting position. In the non-use position, the support arm is disengaged.
  • a coupling of the movement of the pivot module with the pivotal movement of the support arm When the pivot module is moved from the sitting position into the lying position or back, the pivoting of the support arm is positively guided. The user is relieved by the positive guidance of the support arm of a manual operation of the support arm.
