    CONVERSION SYSTEM OF A FURNITURE TO CONVERT A SOFA IN
    BED AND VICEVERSA
    Object of the invention
    The present invention relates to a system for converting a piece of furniture to convert a sofa into a bed and vice versa that is intended to facilitate the operations of converting a sofa into a bed and vice versa. The conversion system occupies a small space; standing out also that its installation is located in lateral areas of the furniture, which allows to take advantage of internal spaces of the furniture assembly to store objects, even in these internal spaces you can mount drawers.
    Technical problem to solve and background of the invention
    Currently, two types of furniture conversion systems are known to convert a sofa into a bed and vice versa; where the furniture includes a bed frame structure that is foldable and can adopt a first deployed position to convert the furniture into a bed; and a second folded position to convert the furniture into a sofa, where in this second folded position the bed frame structure is collected and hidden within an interior space of the furniture.
    To convert the sofa furniture into a bed, the bed frame structure is pulled out, either by dragging a lower part of the sofa, or by pulling up on the lower part of the sofa.
    The problem of this conversion system lies on the one hand, in that the lower part of the furniture is completely disabled, that is, it cannot be used as a storage area, since said lower part is needed to house part of the bed frame structure and / or to be able to carry out the folding and unfolding of said bed frame structure.
    On the other hand, these conversion systems require a significant physical effort to extract and re-store the bed frame structure.
    Finally, it should be noted that in the case of the conversion system in which the

    box spring structure by dragging (for example through the use of wheels); said conversion system has the added disadvantage that the contact of the wheels with the ground can scratch the surface of said ground.
    Another type of conversion system known to convert a sofa furniture into a bed is one in which the back of the furniture is folded back in sofa mode, thus turning the sofa into a bed.
    The problem with this conversion system described in the previous paragraph is that the sofa must necessarily be separated a certain distance from a wall so that the backrest can be folded down and the sofa can be turned into a bed. In these furniture where the backrest is foldable, the limitation must also be added as regards the length of the backrest and therefore the bed.
    Also, in line with what was said in the previous paragraph, to convert the bed mode back to the sofa mode, it is necessary to lift the backrest from the back with the great physical effort that this entails.
    Description of the invention
    In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a system for converting a furniture to convert a sofa into a bed and vice versa comprising a pair of lower guides and a pair of upper guides that are located in opposite lateral areas of the furniture; where the upper guides are located above the lower guides.
    The conversion system also comprises two articulated structures that connect a first seat frame and a second backrest frame; where the articulated structures are coupled to the lower guides and the upper guides.
    Each articulated structure comprises a first arm connected to the first frame and a second arm connected to the second frame.
    The first arm and the second arm are coupled to each other by a common joint; where the first arm is coupled to the lower guide by a first connecting element, and the second arm is coupled to the upper guide by a

    second articulated connection element.
    The two articulated structures have mobility along the lower gwas and the upper guides; where the conversion system is configured so that during the mobility of the two articulated structures the second arms swing an angular space with respect to the first arms around the common joints.
    The lower guides comprise straight paths, while the upper guides comprise initial straight sections and final arcuate sections that are continuation of the initial straight sections; where the conversion system is configured so that during the course of the second articulated connection elements of the second arms along the arcuate sections of the upper guides, the second arms swing with respect to the first arms by varying the existing angular space between these arms.
    The arched sections of the upper guides are curved convergently towards the lower guides.
    The conversion system comprises parallel lateral guides located below the lower guides; where in said lateral guides the first seat frame is coupled; and where the side guides are configured to guide and support the first seat frame.
    The first seat frame is attached to the first arms by means of first pieces and the second backrest frame is connected to the second arms by means of second pieces.
    Each first connection element of the first arm and each second articulated connection element of the second arm are linked by an actuator that is coupled to said connection elements, respectively, by a lower articulation and by an upper articulation.
    The lower guides and the upper guides are located on two plates fixed to the sides of a cabinet frame; where the lower guides and the upper guides comprise through grooves that pass through said plates.

    located in correspondence with the two sides 1a of the furniture frame 1.
    Each articulated structure 5 comprises a first arm 5a and a second arm 5b coupled to each other by means of a common joint 8 located above the respective lower gwa 2.
    In turn, each of the first arms 5a is guided in the lower guide 2 by a first connection element 9 integral with the first arm 5a, while each of the second arms 5b is guided in the upper guide 3 by a second articulated connection element 10 integral to the second arm 5b.
    Thus, when the conversion system of the invention is acted upon, the first and second connection elements 9, 10 together with the first and second arms 5a, 5b of the two articulated structures 5 are guided along the lower guides 2 and upper 3.
    In each of the articulated structures 5, the first connection element 9 of the first arm 5a and the second articulated connection element 10 of the second arm 5b are linked by an actuator 11 that is coupled to said connection elements 9, 10, respectively , by means of a lower articulation 12 and an upper articulation 13. Said actuator 11 is pneumatic or hydraulic.
    The two actuators 11 help to convert the sofa to bed with the utmost effort and vice versa.
    Each of the plates 4 has two opposite faces: a first face and a second face. In correspondence with the first face of the plate 4 the actuator 11 is located, and in correspondence with the second face of the plate 4 the articulated structure 5 is located.
    In order to accommodate the actuators 11, in one embodiment of the invention it is provided that the sides 1a of the frame of the furniture 1 include recesses not shown in the figures. In another embodiment to accommodate the actuators 11, delimited separation spaces are provided between the plates 4 and the sides 1a of the furniture frame 1; where said spaces of separation are not represented in the figures either.

    On the other hand, the first seat frame 6 is coupled to parallel side gwas 14 fixed to the sides 1a of the furniture 1; wherein said lateral gwas 14 are located below the lower guides 2, and where in an embodiment of the invention said lateral gwas 14 are straight and comprise a telescopic structure.
    The first seat frame 6 is connected to the first arms 5a by means of first pieces 15 and the second backrest frame 7 is connected to the second arms 5b by means of second pieces 16. A seat element 6a is mounted on the first frame 6 and on the second frame 7 a backrest element 7a is mounted.
    In an embodiment of the invention the seat element 6a and the backrest element 7a are independent elements; while in another embodiment of the invention the seat element 6a and the backrest element 7a are two elements that are joined together by a hinged; such as two mattresses joined by a common edge.
    On the first seat frame 6 is fixed a crossbar 17 which is used to manipulate the conversion system to convert the sofa into a bed or vice versa; wherein said stringer 17 is located in correspondence with a front of the furniture 1 where the first frame 6 protrudes together with the seat element 6a in the deployed position of the invention system in bed mode.
    In a folded position of the conversion system in the sofa mode, the second frame 7 together with the backrest element 7a are arranged in a substantially vertical position, while the first frame 6 together with the seat element 6a are arranged in a horizontal position .
    In contrast, in a deployed position of the bed mode conversion system, the second frame 7 together with the backrest element 7a are arranged in a horizontal position, while the first frame 6 together with the seat element 6a are also arranged in a horizontal position protruding outward from the front of the furniture 1.
    On the other hand, the lower guides 2 and the upper guides 3 are delimited by
    5

    opposite ends: rear ends and front ends that are closer to the front of the furniture 1 than the rear ends; where the front ends of the upper gwas 3 are part of their curved sections 3b that converge towards the front of the furniture 1 and also converge towards the lower gwas 2.
    In line with what has been said in the previous paragraph, the front ends of the lower guides 2 are closer to the front of the furniture 1 than the front ends of the upper guides 3, so that the lower guides 2 have additional sections 2a that protrude with respect to the anterior ends of the upper guides 3; where said additional sections 2a and the arcuate sections 3b of the upper guides 3 allow the first arms 5a and the second arms 5b of the articulated structures 5 to come together and contact each other in the deployed position in bed mode, making the first frame 6 and the second frame 7 are aligned horizontally in said deployed position in bed mode.
    Starting from the folded position in sofa mode, to transform to the bed mode, said stringer is pulled17, where with this operation the first frame 6 and also the second frame 7 will be moved until reaching the total unfolding position in which the two frames , first 6 and second 7, are placed in a horizontal plane to form a bed formed by the seat element 6a associated with the first frame 6 and the backrest element 7a associated with the second frame 7. In said total deployment position, the element of seat 6a has a support surface that is coplanar to another support surface of the backrest element 7a.
    In the total deployment position in bed mode, the positioning of the second backrest frame (7) is maintained in a stable position because the second arms (5b) are in contact with the first arms (5a) of the two articulated structures (5).
    Also, starting from the position deployed in bed mode, to transform to the sofa mode, said stringer 17 is pushed into the furniture 1, where with this operation the first frame 6 and also the second frame 7 will be moved until reaching the folding position wherein the first frame 6 together with the seat element 6a are kept in a horizontal position and the second frame 7 together with the backrest element 7a is located in a substantially vertical position.

    During the folding and unfolding operations to reach the sofa mode or the bed mode by means of the conversion system of the invention, the first connection elements 9 and the second connection elements 10 of the two articulated structures 5 are guided at all times. along the lower guides 2 and upper 3; where the first arms 5a move in parallel directions along the lower guides 2, while the second arms 5b are dragged by the first arms 5a, while said second arms 5b swing around the common joint 8 by varying their relative positions with respect to the first arms 5a.
    During folding and unfolding operations, the second backrest frame 7 is held in a substantially vertical position while the second connecting elements 10 of the second arms 5b are located along the straight sections 3a of the upper guides 3.
    On the other hand, when said second connection elements 10 of the second arms 5b reach the arcuate sections 3b of the upper guides 3, the inclination of the second backrest frame 7 progressively varies; all of this as shown in Figures 4a to 4c, so that when the second connecting elements 10 reach ends of said arcuate sections 3b of the upper guides 3, the second backrest frame 7 is placed in the horizontal position.
    During said folding and unfolding operations, the distance between the first joint 12 and the second joint 13 of each actuator 11 varies.
    Thanks to the two actuators 11, a minimal effort is made in the transformation from sofa to bed and vice versa, in which the lower guides 2 and upper 3, as well as the lateral guides 14, also participate, so that the two actuators 11 help in the movement of the two frames 6, 7 reducing the effort required to apply.
    It should also be noted that during the folding and unfolding operations the lower frame 6 is guided at all times in the lateral guides 14 and is also guided by the first arms 5a along the lower guides 2.
    Thus, thanks to the configuration and disposition of the conversion system of the
    Invention, to move from the sofa mode to the bed mode is achieved by pulling the stringer17 out of the furniture 1, where with this operation the sofa mode of the furniture 1 is transformed into bed mode; while to move from the bed mode to the sofa mode, the furniture 1 is pushed into the crossbar 17, so that the bed mode 5 returns to its original sofa position; emphasizing that it is not necessary to manually lift the assembly of the second frame 7 and the backing element 7a.
    It is emphasized that no space is used in the lower area of the furniture 1 below the lateral guides 14, which makes it especially advantageous for the storage of objects; You can even mount some drawers 18 to store these objects.
    The advantage that the furniture can be located in an area adjacent to a wall is also highlighted, so that there would be no problem when converting 15 sofa beds, it is not necessary to separate the furniture from said wall, since the folding of the assembly of the second frame 7 and backrest 7a is carried out together with an advance movement towards the front of the furniture 1 where the crossbar 17 is located.
