Definitions

  • the present invention relates to a convertible piece of furniture which can be converted from a sofa and/or single bed into a bunk bed.
  • the prior art includes several sofas that can be converted into one bed and, and sofas that can be converted into two beds within the space occupied by a bed, but these prior art sofas are scarcely capable to perform all the functions adequately.
  • Another drawback of the prior art is that the second bed, even when used under the elevated single bed, cannot be considered a true bunk bed, since the space between the two beds is not sufficient to make it a true bunk bed, and the second bed is in any case at a considerably lower level than a normal bed.
  • Another drawback of the prior art is that even when the second bed meets the requirement of optimizing space, being arranged under the single bed, it does not always comply with maximum safety requirements, especially regarding its deployment.
  • the aim of the present invention is to obviate the drawbacks of the cited prior art, by providing a piece of furniture which can be easily converted from a sofa and/or single bed into a bunk bed.
  • An object of the present invention is to provide a piece of furniture which is equally comfortable as a sofa, as a single bed and as a bunk bed.
  • a further object of the present invention is to provide a piece of furniture in which the space below the sofa is used to store a true bed without any particular limitation regarding for example the thickness of the bed or mattress when stored and to its distance from the ground when pulled out, because the bed leaves its storage space by rotation and arranges itself in a bunk bed-like arrangement above the other bed.
  • a further object of the present invention is to provide a piece of furniture which optimizes space by letting the second bed being arranged above the single bed.
  • a further object of the present invention is to provide a piece of furniture which, when used as a bunk bed, maintains between the two beds the space that is typical of bunk beds, without forcing the user to sit on the lower bed in uncomfortable crouching positions.
  • a further object of the present invention is to provide a piece of furniture which can be used and handled practically and without danger or effort for the users.
  • a further object of the present invention is to provide a piece of furniture at an economically advantageous cost.
  • the piece of furniture according to the invention comprises two half-frames 1 each constituted by a C-shaped member, made for example of quadrangular metal tube, which is frontally rigidly coupled to posts 8, constituted for example by a U-shaped metal profile.
  • Rods 2, preferably made of metal tube, are rigidly coupled to half-frames 1, for example by means of screws or other fasteners, and act as a support for the unit.
  • Half-frames 1 are mutually connected by longitudinal members 3, 4 and 5, which are made for example of quadrangular metal tube, coupled by welding, and acting as braces.
  • a second pair of half-frames 9, symmetrical and identical to half-frames 1, are arranged in a front region and are connected to the half-frames 1 by the two hinges 10 which are rigidly coupled, for example by welding, to half-frames 1 and 9.
  • a bedspring 11 and longitudinal members 12 and 13 are rigidly coupled, for example by welding, to half-frames 9; the longitudinal members act as braces and support for the covering panel 14.
  • the bedspring 15 is arranged inside half-frames 1 and rests on the longitudinal members 3 and 5 and on the adjustable supports 16 rigidly coupled to the bedspring 11.
  • Brackets 17 are rigidly coupled to the bedspring 15 in a rear region, for example by welding, and are articulated to the pair of pivots 18 rigidly coupled to half-frames 1.
  • bedspring 15 has a mattress retention frame 19 made of shaped metal tube.
  • a foldaway ladder 60 constituted by a deformable-parallelogram, is articulated to the bedspring 11 which is rigidly coupled to half-frames 9 and is arranged below the bedspring 15 so that the supporting surface is directed downward.
  • the ladder 60 comprises a short post 20, a long post 21, three rungs 22, 23 and 24, a safety barrier 25 and a rod for the barrier 26.
  • Rungs 22, 23 and 24 are articulated to the posts 20 and 21 about the pivots 27, 28, 29, 30, 31 and 32.
  • the barrier 25 is articulated to the post 21 about the pivot 33 and to the rod 26 about the pivot 34, while, at its other end, the rod 26 is articulated to the bedspring 11 about the pivot 35.
  • the posts 20 and 21 are pivoted about the pivots 36 and 37 which are rigidly coupled to the plates 38 and 39, which are welded to the bedspring 11.
  • the spring/damper unit 41 is articulated to the plate 39 about the pivot 40 and is articulated, at its other end, about the pivot 42 which is rigidly coupled to the post 21.
  • the ladder By slightly pushing the posts 20 and 21 of the ladder 60 as described, the ladder turns counterclockwise about the pivots 36 and 37, so that the system constituted by the ladder and the barrier and composed of deformable parallelograms arranges itself horizontally, supported by the spring/damper unit 41, varying its dimensions until it folds up completely and horizontally.
  • the post 21, which is coaxial to the rod 26, can reach the end of its stroke only after it has been forced manually to superimpose itself on the rod 26, through producing a spring effect which helps to keep the system in the horizontal position (in Figure 3 the folded position of the ladder 60 and of the barrier is shown in dashed lines).
  • a spring/damper unit 45 is articulated between one of the half-frames 1 and the bedspring 15, at the points 43 and 44, and facilitates the partial overturning of the bedspring 15 and of the corresponding mattress 46, required for subsequently pulling out, by rotation, the second bedspring 11 and the corresponding mattress 47.
  • the spring/damper unit 48 is articulated about the pivot 49, which is rigidly coupled to the lug 50 which is welded inside the U-shaped metal profiled member 8 and, at its other end, about the pivot 51, which is rigidly coupled to the lug 52 which is welded inside the U-shaped metal profiled member 53, so that in the closed position, since the pivot 51 is axially offset with respect to the articulation 49 and to the hinge 10, it keeps the pair of mutually hinged frames 1 and 9 in a stably closed position.
  • the spring/damper unit 48 is therefore arranged, during maximum compression, inside the pair of U-shaped profiled members 8 and 53, which conceal it from view when the piece of furniture is closed.
  • the padding components of the back rest 54 can be stored on the supporting surface 55.
  • the bedspring 15 and the corresponding mattress 46 are repositioned horizontally and are supported by the longitudinal members 3 and 5, while the second bed becomes accessible after turning, through 90°, the ladder and the corresponding barrier, which are folded frontally and horizontally, by gripping for example the post 21 and turning it clockwise, with the assistance of the spring/damper unit 41, with a weight balancing function, until the ladder is unfolded vertically and the barrier is simultaneously lifted. This operation opens the chain of parallelograms that constitutes the ladder-barrier assembly.
  • a piece of furniture which is converted, by rotation, from a sofa and/or single bed to a bunk bed, according to the present invention, which includes: a pair of vertical metal frames which are rigidly coupled to a pair of horizontal rods with a supporting function and are mutually connected by four horizontal longitudinal members; a bedspring, which is hinged inside the frames and also acts as support for the seat; a second pair of vertical metal frames, which is symmetrical and arranged in a forward position with respect to the first one and is connected by two horizontal longitudinal members; a metal tube frame, which is rigidly coupled to the frame pair and acts as a bedspring for the second bed; a ladder, constituting a deformable parallelogram, having a related barrier and being articulated to the bedspring of the second bed.
  • the frame pairs are mutually hinged in the front and upper region, so that after partially turning over the bedspring of the first bed, with the aid of the thrust of a spring/damper unit, and by turning through 180° the pair of front frames and the bedspring that is rigidly coupled thereto with the aid of another spring/damper unit, the bedspring and the corresponding mattress that were arranged upside down under the surface of the first bed are now arranged adequately above the surface and in the position for use as bunk bed, stably supported by the pair of underlying twin frames.
  • the ladder and the corresponding barrier following the rotation of the second bed, are folded horizontally in a front position.
  • the ladder By virtue of the simple rotation of a post, the ladder, by turning on two pivots which are rigidly coupled to the bedspring, folds out and opens so as to be arranged in a vertical position to support the bedspring, while at the same time the barrier, which is articulated to the ladder, rises. Conversion to a bunk bed is thus obtained without effort and with a small number of simple and safe movements.
  • the piece of furniture By performing these operations in reverse, the piece of furniture can be arranged in the folded, or closed, position again, acting as a single bed which is a comfortable sofa, equipped with adapted cushions supported by one of the longitudinal members of the first bed.
  • the cushions or pillows can be stored under the first bed when the furniture unit is used as a bunk bed.
