[0057] like Figures 1 to 2 As shown, the sofa 1 of the present application includes at least two bases 10, at least two backrests 11, and two armrests 12. The two bases 10 constitute the seat portion of the sofa 1 and can be folded together. At least two backrests 11 are respectively provided on one side of the two bases 10, forming the backrest portion of the sofa 1, and the backrests 11 can be folded together. The armrests 12 are respectively provided at both ends of the seat portion and have cavities 120 that can accommodate the folded backrests 11 or at least a portion of the base 10.

[0058] The sofa 1 provided in the present application adopts a segmented foldable base 10 and backrest 11, and an armrest 12 with a cavity 120, which can reduce the overall weight and save materials; it can also achieve that the folded base 10 or backrest 11 can be inserted into the cavity 120 of the armrest 12 during transportation packaging, fully utilizing the space and reducing the volume of the transportation packaging.

[0059] The base 10 includes a frame and a support plate disposed within the frame. The support plate can be formed by splicing together multiple support strips or a single piece. The support plate can be fixed to the frame or detachably connected to the frame. The support plate is typically made of wood, such as pine, oak, beech, fiberboard, particleboard, plywood, density fiberboard (MDF), etc. The frame is typically made of metal to enhance the overall strength of the sofa. The frames are detachably connected or rotatably connected relative to each other, such as by hinged connections.

[0060] In this embodiment, "base folding" refers to stacking at least two bases 10 along their thickness direction, where the thickness direction of the base 10 is perpendicular to the support plate surface. When stacking at least two bases 10 along their thickness direction, adjacent bases 10 can be stacked directly, other sofa components can be placed between them, or individual bases 10 can be packaged before stacking. The folded bases 10 can be connected at their edges or separated and then folded.

[0061] The base 10 may further include a base cushion. The base cushion is generally soft and can be rolled up or folded when packaged. When folding, the base cushion can be separated from the base 10 and folded separately, or it can be folded together as long as it can be accommodated in the cavity 120 of the armrest 12 of the sofa 1.

[0062] The backrest 11 includes a backrest board and a backrest cushion located in front of the backrest board. It is generally believed that when a user sits on the sofa 1, the user's calf is located in the "front" of the torso. The "front" referred to in this application is the same as the "front" of the user. The backrest board is usually made of wood, such as pine, oak, beech, fiberboard, particleboard, plywood, density board (MDF board), etc. The backrest cushion is usually soft and can be rolled up or folded when packaged. When folding the backrest cushion, the backrest cushion can be separated from the backrest board and folded separately, or it can be folded directly without separation, as long as it can be accommodated in the cavity 120 of the armrest 12 of the sofa 1.

[0063] In this embodiment, "backrest folding" refers to stacking at least two backrests 11 along their thickness direction, where the thickness direction of the backrest 11 refers to the direction perpendicular to the backrest board surface. When stacking at least two backrests 11 along their thickness direction, adjacent backrests 11 can be stacked directly, or other components of the sofa 1 can be placed between adjacent backrests 11. Alternatively, individual backrests 11 can be packaged first and then stacked. The connections between the backrests can be detachable. When folding, the folded backrests 11 can be connected together at their edges or separated before folding.

[0064] In this embodiment, the sofa 1 further includes at least two front panels 13, which are positioned on the side of the base 10 away from the backrest 11. This means that when a user sits on the sofa 1, their calves are positioned in front, and their torso is positioned in the back. The front panels 13 are positioned close to the user's calves, while the backrest 11 is positioned close to the user's torso. The provision of the front panels 13 helps maintain the integrity of the sofa 1, improving its durability and overall aesthetics. The front panels 13 can also be folded and stored in the cavities 120 of the armrests 12 during transport.

[0065] The number of front baffles 13 can be one or more. When there is only one front baffle 13, to further reduce the packaging volume of the sofa 1, an opening and closing seam can be provided on at least one surface of the front baffle 13. For example, the front baffle 13 can be made of sponge, and the opening and closing seam can be formed by cutting the front baffle 13. The depth of the opening and closing seam is less than the thickness of the front baffle 13, and the opening and closing seam extends to the thickness surface of the front baffle 13, facilitating folding while maintaining the integrity of the front baffle 13. The depth of the opening and closing seam can be selected based on the material of the front baffle 13, as long as it facilitates folding of the front baffle 13 and ensures its integrity.

[0066] When there are two or more front baffles 13, the front baffles 13 can be independent or connected together. The front baffles 13 can be directly connected to the base 10, can be indirectly connected to the base 10, or can be connected between the two armrests 12 without being connected to the base 10.

[0067] It should be understood that when the number of front baffles 13 is greater than or equal to two, the number of bases 10 and the number of front baffles 13 may be the same or different. This embodiment is described in detail by taking the example of two bases 10 and two front baffles 13 as examples.

[0068] In this embodiment, the front panels 13, base 10, and backrest 11 are identical in number. This equivalence simplifies the fabrication of the sofa 1 and enhances the aesthetics of the assembled sofa 1. Since the base 10, backrest 11, or front panels 13 can all be folded and accommodated within the armrest 12's cavity 120, their equal number maximizes the utilization of the armrest 12's cavity 120, preventing any interference in one direction from wasting space within the armrest 12's cavity 120. This equal number also allows for smaller, more uniform packaging of the sofa 1. A larger number of sofas can fit within the same container space, reducing shipping costs and improving economic efficiency.

[0069] In other embodiments, the number of front baffles 13, bases 10, and backrests 11 may be different. For example, one front baffle 13 corresponds to two bases 10 and three backrests 11; or two front baffles 13 correspond to three bases 10 and two backrests 11, and so on.

[0070] In this embodiment, the armrest 12 has a bottom surface 121 facing the ground and having an opening 122 defined therein. The cavity 120 accommodates the folded backrest 11 or base 10 through the opening 122. Disposing the opening 122 of the cavity 120 on the bottom surface 121 of the armrest 12 facing the ground, that is, with the opening 122 of the armrest 12 facing downward, allows the size of the opening 122 to be maximized while ensuring the strength of the armrest 12. This facilitates accommodating more of the other components of the sofa 1 within the cavity 120 of the armrest 12, thereby reducing the packaging volume.

[0071] like Figure 3 As shown, in this embodiment, the armrest 12 includes two first bottom plates 123 and two second bottom plates 124 disposed opposite each other, surrounding an opening 122. The two first bottom plates 123 are connected to the ends of the two second bottom plates 124. Using the two first bottom plates 123 and the two second bottom plates 124 to enclose the opening 122 maximizes the size of the opening 122 and provides sufficient strength for the armrest 12 at the opening 122. Using the two first bottom plates 123 and the two second bottom plates 124 to connect the ends of the two second bottom plates 124 improves the firmness and stability of the armrest 12 at the opening 122, thereby increasing the strength of the armrest 12 and, consequently, the sofa 1.

[0072] In this embodiment, except for the bottom surface 121 having an opening 122, the rest of the surfaces of the armrest 12 are complete surfaces, and a reinforcing strip (not shown in the figure) is provided inside the armrest 12 to strengthen the strength of the cavity 120. The reinforcing strip can be made of wood, such as pine, oak, beech, fiberboard, particleboard, plywood, density board (MDF board), etc., or metal. The two first bottom plates 123 and the inner second bottom plate 124 can be made of plywood, and the outer second bottom plate 124 can be made of solid wood, so that the outer side of the armrest 12 is stronger. The side of the armrest 12 facing the base 10 of the sofa 1 is the inner side of the armrest 12, and the side of the armrest 12 facing away from the base 10 of the sofa 1 is the outer side of the armrest 12.

[0073] like Figure 4As shown, in some other embodiments, the armrest 12 has a bottom surface 121 and front and rear side surfaces perpendicular to the bottom surface 121, and the front and / or rear side surfaces are rectangular frame structures 125. Providing the front and rear side surfaces of the armrest 12 as rectangular frame structures 125 can save material, further reduce the weight of the armrest 12, and accommodate larger sofa parts within the cavity 120 of the armrest 12. For example, a portion of the sofa structure can be placed through the rectangular frames of the front and rear side surfaces, further reducing the packaging size and fully utilizing the cavity 120 of the armrest 12. The rectangular frame structure 125 should be made of a relatively strong material, such as solid wood or metal.

[0074] In this embodiment, the rectangular frame structure 125 includes two opposing connecting plates 501 and two opposing connecting rods 502. The two connecting plates 501 are connected to the two connecting rods 502, or the two connecting rods 502 are connected to the two connecting plates 501. This design allows for a larger space enclosed by the connecting rods 502 and the connecting plates 501, while also ensuring that the strength of the armrest 12 is not significantly reduced. The connection of the two connecting plates 501 to the two connecting rods 502, or the connection of the two connecting rods 502 to the two connecting plates 501, improves the firmness and stability of the armrest 12 at the opening 122, thereby increasing the strength of the armrest 12 and, consequently, the strength of the sofa 1.

[0075] In the above embodiments, Figures 5 and 6 As shown, a reinforcement member 101 is disposed between the two bases 10, and a connector 110 is disposed between the two backrests 11, with the connector 110 abutting against the reinforcement member 101. The sofa 1 of the present application, through the abutment between the reinforcement member 101 and the connector 110, can further secure the connection between the backrest 11 and the base 10. When a user sits on the sofa 1 and leans against the backrest 11, the base 10 can provide a certain amount of support to the backrest 11 through the reinforcement member 101, which helps the backrest 11 support the user, making the sofa 1 more comfortable and durable.

[0076] The reinforcement 101 can improve the connection strength of the base 10 and improve the stability of the sofa 1. The reinforcement 101 between the two bases 10 can be integrally formed with the base 10, or can be separately formed and fixed to the base 10, or can be detachably connected to the base 10.

[0077] The provision of the connecting member 110 can not only realize the connection and assembly between the backrests 11 , but also realize the connection and assembly between the backrest 11 and the base 10 , and can also make the backrest 11 more firm.

[0078] In the above embodiments, Figure 7As shown, the connector 110 includes a connecting post 111, two first plug-ins 112, and two second plug-ins 113. The first plug-ins 112 and the second plug-ins 113 cooperate to connect the backrests 11. The first plug-ins 112 are fixed to opposite sides of the connecting post 111, and the second plug-ins 113 are fixed to the backrests 11. The connector 110, which adopts the form of connecting post 111 and plug-ins 112 and 113, facilitates the connection between the backrests 11 and the base 10, and also provides higher strength. The second plug-ins 113 can be fixed to the side of the two backrests 11 that are close to each other.

[0079] The two first plug-ins 112 are fixedly mounted on both sides of the connecting column 111 by means of fasteners such as bolts, and the two second plug-ins 113 are fixedly mounted on the sides of the backrest 11 by means of fasteners such as bolts. When the sofa 1 is assembled, the two backrests 11 are respectively mounted on both sides of the connecting column 111 by means of the cooperation of the first plug-in 112 and the second plug-in 113 to form an integral backrest portion, so that the front surfaces of the two backrests 11 are substantially in the same plane.

[0080] In the above embodiments, Figure 7 As shown, the connecting column 111 further includes a supporting member 114 provided at one end of the connecting column 111 . The connecting member 110 is pressed against the reinforcing member 101 via the supporting member 114 , so that the connection between the connecting member 110 and the reinforcing member 101 is more secure and the force is evenly distributed.

[0081] See also Figure 7 As shown, the abutment member 114 is a groove-like structure with two ends extending through it, and is generally U-shaped. The bottom of the groove of the abutment member 114 is welded to the bottom end of the connecting column 111, and the notch of the abutment member 114 faces the base 10. When the backrest 11 is installed on the base 10, the reinforcement member 101 of the base 10 is confined within the U-shaped groove of the abutment member 114. The abutment member 114 may also have a rear end, so that when the user leans on the backrest 11, the rear end of the support member can abut the inner edge of the rear side frame of the base 10. When the number of backrests 11 is different from the number of bases 10, for example, when there are three backrests 11 and two bases 10, another reinforcement member 101 can be provided on the base 10 at the position corresponding to the abutment member 114. In this case, the reinforcement member 101 may be located at one of the bases 10, rather than between the two bases 10.

[0082] In another possible design, a socket with a notch facing the backrest 11 may be provided on the base 10 , and the connecting column 111 is inserted into the socket.

[0083] In the above embodiments, Figure 7As shown, the first plug-in 112 and / or the second plug-in 113 have a through-slot 115. The first plug-in 112 and / or the second plug-in 113 cooperate and connect with each other through the through-slot 115. The width of the through-slot 115 gradually decreases as it approaches the base 10. The through-slots 115 cooperate to achieve connection between the plugs, and thus achieve connection between the backrests 11 to be connected, which can facilitate disassembly and ensure a secure connection. As the width of the through-slot 115 gradually decreases as it approaches the base 10, it can enable the through-slot 115 to function as both a connection and a limit, and this design also makes the connection more stable.

[0084] During assembly, the second plug-in 113 is inserted into the first plug-in 112 from above the first plug-in 112. The inclination of the groove wall of the through groove 115 of the second plug-in 113 is adapted to the inclination of the groove wall of the through groove 115 of the first plug-in 112. Since the width of the through groove 115 gradually decreases in the direction approaching the base 10, when the second plug-in 113 is inserted to a certain position, it will be supported by the two groove walls of the first plug-in 112, and the second plug-in 113 will no longer move downward. At this time, the assembly is in place.

[0085] In another embodiment, a protrusion is provided on the inner side wall of the through slot 115 of the first plug 112 or the outer side wall of the through slot 115 of the second plug 113. When the second plug 113 no longer moves downward due to the protrusion, the assembly is in place. Other types of structures that limit the downward movement of the second plug 113 can also be provided.

[0086] This application also provides a sofa assembly, which can be referenced Figure 8 The sofa is the sofa 1 described above, wherein in this assembly, a portion of the backrest 11 or base 10 of the sofa 1 is accommodated in the cavity 120 of one armrest 12, and the other portion is accommodated in the cavity 120 of the other armrest 12. This assembly is typically used for a three-seater sofa 1 (only the base 10 and backrest 11 are longer in length, and there are usually two bases 10 and backrests 11). Using a plug-in packaging method, the backrest 11 or base 10 is folded and inserted into the cavity 120 of the armrest 12. At this time, the armrest 12 is in a state where the opening 122 of the cavity 120 is facing each other, allowing the base 10 or backrest 11 of the three-seater sofa 1, which has a larger length dimension, to be fully inserted into the cavity 120 of the armrest 12, thereby reducing the packaging size of the three-seater sofa 1 and facilitating transportation.

[0087] The openings of the armrests 12 can be butted together so that the armrests 12 wrap around the backrest 11 and / or the base 10. When the backrest 11 or the base 10 is large and the armrests 12 are small, a gap may exist between the two armrests 12, exposing the middle portion of the backrest 11 and / or the base 10.

[0088] In addition, the components of the sofa 1 also include a compressed package of the base cushion and the back cushion, the wooden slats or boards of the base 10, the sofa legs 100, and fixing screws, etc. The frame of the base 10 is placed above the two armrests 12, and the wooden slats or boards of the base 10, the sofa legs 100, the fixing screws, the compressed package of the base cushion and the back cushion, etc. can be placed inside the frame.

[0089] Figures 9 and 10 The diagram shows the assembly of a two-seater sofa 1 (only the base 10 and backrest 11 are shorter in length, and there are typically two bases 10 and backrests 11). The base 10 or backrest 11 is accommodated in the cavity 120 of the armrest 12. In this embodiment, the backrest 11 and front panel 13 are accommodated in the cavity 120 of the armrest 12. The two armrests 12 are stacked together to form the assembly of the two-seater sofa 1. Because the base 10 and backrest 11 are shorter in length, the base 10 can be folded and inserted into the cavity 120 of the armrest 12, and the backrest 11 can be folded and inserted into the cavity 120 of the other armrest 12, fully utilizing the space in the cavities 120 of the armrests 12 of the sofa 1. Furthermore, the assembly of the sofa 1 also includes compression packs for the base and backrest cushions, wooden slats or boards for the base 10, sofa legs 100, and fixing screws. The frame of the base 10 is placed above the two armrests 12, and the wooden slats or wooden boards of the base 10, sofa legs 100 or fixing screws etc. can be placed inside the frame. The compressed package of the base cushion and the backrest cushion is placed on the side of the two armrests 12.

[0090] like Figure 8 As shown, the present application provides a method for transporting and packaging a sofa, wherein the sofa is the sofa 1 described above, and the packaging steps are as follows: Step S1: Fold the backrest 11 and the base 10. Step S2: Insert a portion of the folded backrest 11 and / or base 10 into the cavity 120 of one armrest 12. Step S3: Insert another portion of the folded backrest 11 and / or base 10 into the cavity 120 of the other armrest 12.
