Definitions

  • the invention relates to a piece of furniture designed as a corner sofa with a substantially L-shaped seat surface and a functional portion which is arranged in a sitting position behind the seat surface as a backrest,
  • the object of the invention is to develop a generic corner sofa to the effect that this can be advantageously used as a sofa bed.
  • this is achieved by a generic piece of furniture, wherein the functional portion relative to the seat between the seating position and a reclining position in which it is arranged in a free space bounded by the seat on two sides, movable, wherein in the lying position an outer surface of the functional portion at least partially aligned with the seat.
  • the functional section is arranged in the reclining position such that it at least partially fills the free area between the two parts of the seat which are angled relative to one another and thus completes an approximately rectangular reclining surface.

  • the other part of the lying surface is formed by the other, preferably longer part of the seat together with the outer surface of the functional portion.
  • it does not require a particularly deep seat and no particularly high functional section to allow for a sufficiently long adult lying surface.
  • a particular advantage resulting from the construction according to the invention is that the L-shaped seat surface can be used as a lying surface without displacement or only slight displacement of the two legs of the seat. This allows a particularly high stability of the furniture. It is also particularly advantageous in the design according to the invention that the movement of the functional section acting as a backrest into the outdoor area can be dispensed with in order to pull forward the seat surface or a supplementary lying surface section arranged beneath the seat surface for producing a lying surface.
  • the functional portion is movably connected by a first lever with the fixed seat or with a stationary base of the furniture, wherein the first lever is pivotally mounted on the functional portion about a first pivot axis and on the seat surface or the base about a second pivot axis and wherein Lever is arranged completely in a gap at least in the sitting position of the functional portion, said gap being bounded by a side surface of the padding adjoining the seat surface, a side surface of the functional portion and / or a lateral part terminating the furniture laterally.
  • the base frame may comprise, for example, a stationary frame of the piece of furniture arranged underneath the seat and / or stationary side pieces.
  • the lever preferably has two mutually spaced apart in the direction of the pivot axes lever elements which are moved together during a movement of the functional portion.

  • the gap is preferably bounded by mutually parallel surfaces, which are preferably padded surfaces which abut each other where the lever is not disposed.
  • the arrangement of the lever or the lever elements in this gap a particularly aesthetic design is possible because the lever is not visible, at least in the seating position of the functional section.
  • the lever or the lever elements are arranged in the lying position of the functional portion at least for the most part in this gap or columns.
  • the gap is bounded on one side by a side part, for example a side rest, and bounded on the other side by a side face of the functional section and / or a side face of the seat upholstery.
  • the gap may also be bounded on both sides by side surfaces of the padding adjoining the seat surface, so that it interrupts the otherwise closed seat surface.

  • Such a configuration allows a particularly advantageous transfer of the functional section in its lying position.
  • the functional portion can change its pivotal position relative to the seat surface during the transfer, which means a collision-free passage of the functional portion the seat allows.
  • the positive guidance device ensures that the orientation of the first lever or the two lever elements, which form the first lever, relative to the seat surface or the lower frame simultaneously determines the orientation of the functional portion relative to the lever. This eliminates the need to simultaneously affect the location and orientation of the functional section manually by appropriate handling. Instead, the functional portion alone assumes the desired position by the movement of the lever relative to the seat surface or the base frame.
