Definitions

  • the invention relates to a piece of furniture that can be brought into a sofa/chair configuration and a bed configuration.
  • a sofa bed or reclining chair has two functions, a sitting function and a lying function. Brining the sofa bed from the sitting function to the lying function requires operations. These operations range from sliding out parts of the sofa, destacking parts of the sofa, folding out parts of the sofa, to disassembling parts of the sofa. As a rule, these are difficult and/or laborious operations or they are difficult to perform by one person. Another drawback may be that the sofa bed is heavy so that, when an additional bed is required in another room, this sofa bed is difficult to move.
  • reclining chairs are known that are built up from an assembly of cushions. If an additional place to sleep is required, the cushions are folded out so that a mattress is formed. However, this reclining chair is not particularly suitable for use in folded condition as a seat. The cushions easily give way due to the weight of the person sitting thereon and this, accordingly, provides an extremely unstable seat.
  • An object of the present invention is to provide a piece of furniture which can easily be brought from a sitting to a lying function and vice versa so that the piece of furniture can easily be operated by one person while the piece of furniture is also easy to move.
  • the invention provides a piece of furniture that can be brought into a sofa/chair configuration and a bed configuration, wherein the piece of furniture is provided with a frame comprising a first frame part provided with a first extremity and a second extremity located opposite the first extremity, a second frame part being hingedly connected to the first frame part at the location of the first extremity, or being slideably connected to the first frame part, a third frame part being hingedly connected to the first frame part at the location of the second extremity, a fourth frame part being hingedly connected to the third frame part, wherein the central axes around which the frame parts hinge relative to each other extend parallel to each other, while, in the sofa/chair configuration, the second frame part lies on the first frame part, the third frame part forming a backrest and the fourth frame part taking up a locking position in which the fourth frame part engages the first or second frame part for holding the third frame part in a backrest position.
  • the piece of furniture can be easily folded from a bed configuration to a sofa/chair configuration.
  • the different frame parts are folded up or displaced separately, one person can perform these operations alone, also because of the manageable sizes of the frame parts.
  • the piece of furniture Owing to the relatively limited dimensions of the piece of furniture in sofa/chair configuration, and owing to the relatively limited weight effected by the construction of the piece of furniture, the piece of furniture can be handled well and can, accordingly, be moved to the desired location by one person.
  • a seat and backrest geared to human dimensions are provided.
  • the first frame part is provided with supporting elements such as, for instance, legs, with the aid of which the frame part can be placed on the ground
  • the second and fourth frame parts are each provided with supporting elements, such as, for instance, legs, with the aid of which these frame parts rest on the groimd when the piece of furniture is in the bed configuration.
  • the supporting elements ensure that the seat part or lying part of the piece of furniture remains, at all times, at a small distance above the ground and is hence not in direct contact with the ground. This has as an advantage that cold penetrates the piece of furniture less easily, which has a comfort enhancing effect. This is of importance especially when the piece of furniture is arranged in the bed configuration and is used as a place to sleep.
  • the legs of the fourth frame part are designed for engaging, in the sofa/chair configuration, the first or second frame part for holding the third frame part in the backrest position relative to the first or second frame part, and for absorbing forces applied to the third frame part.
  • This is particularly favourable to the stability and the robustness of the piece of furniture.
  • the hinges between, in particular, the first and the third frame part are relieved.
  • the legs of the fourth frame part can be provided with a first projection, which engages, with the piece of furniture in the sofa/chair configuration, a top side of the first or second frame part, and with a second projection which engages, in the sofa/chair configuration, a lower side of the first or second frame part.
  • the first or the second frame part can then, on either side, be provided with a lower and an upper recess for receiving therein, at least partly, the first and second projection, respectively.
  • Such projections, with the optionally corresponding recesses provide a stable engagement, so that in the sofa/chair configuration, the third and the fourth frame part are stably positioned relative to the first and second frame part.
  • At least one detachable locking is provided for holding the fourth frame part in the locking position when the piece of furniture is in the sofa/chair configuration.
  • the detachable locking prevents any snapping loose of the fourth frame part when the piece of furniture is in the sofa/chair configuration.
  • the detachable locking absorbs these forces and the fourth frame part remains in place.
  • the detachable locking is formed by a friction-based engagement between the fourth frame part and at least one of the first, second or third frame parts. This entails that the detachable locking can be manufactured in a simple manner. To this end, the piece of furniture needs not comprise any additional elements, which has a favourable effect on the production costs.
  • the central hinge axis of the hinge around which the second frame part can pivot relative to the first frame part is located above the level where a free edge of the second frame part located opposite the hinge is located when it is folded onto the first frame part, such that the second frame part provides a seat proceeding from the third frame part, that forms the backrest, to the hinge in a slightly upward inclining manner.
  • the frame parts are each provided with bearing surfaces on which cushions can be placed for forming a bed, with the piece of furniture in the bed configuration.
  • the cushions which are located on the piece of furniture in the sofa/chair configuration, are used as mattress in the bed configuration.
  • all cushions are placed side by side on the bearing surfaces so that together, the cushions from the mattress.
  • At least one of the bearing surfaces preferably all bearing surfaces, comprise a plate provided with ventilation openings. These openings promote through-flow of air from and to the cushions on the piece of furniture. In particular when the piece of furniture is used in the bed configuration, the cushions will become moist through use. Good ventilation, allowing the cushions to dry, prolongs the lifespan of the cushions.
  • At least one of the bearing surfaces, and preferably all bearing surfaces comprises a number of parallel slats.
  • This has the same advantage as the above-mentioned ventilation openings.
  • a piece of furniture provided with bearing surfaces comprising parallel slats is, in addition, also particularly suitable for use outside, as garden furniture.
  • the parallel slats prevent any rainwater from remaining behind on the piece of furniture, which could be unfavourable to the condition of the material.
  • the parallel slats of the fourth frame part can furthermore be moved between the parallel slats of the first frame part to thus form a friction-based locking for locking the fourth frame part in the sofa/chair configuration relative to the other frame parts.
  • the cushions of the piece of furniture form a mattress and, with the piece of furniture in the sofa/chair configuration, the cushions provide at least a seat and a backrest cushion.
  • the cushion which rests, in the bed configuration, on the bearing surface of the fourth frame part is preferably, in the sofa/chair configuration, located on the side of the third frame part, forming the backrest, remote from the seat.
  • the respective cushion has a length that substantially corresponds to double the distance between the second extremity of the third frame part and the central hinge axis of the hinge connection between the third and fourth frame part.
