DETAILED DESCRIPTION

[0051] The technical solution of the present disclosure will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0052] In the description of the present disclosure, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0054] See also Figures 1 to 15 As shown, this embodiment provides a sofa, including a support frame assembly and a front baffle 12, the support frame assembly includes at least two base frames 11, and two adjacent base frames 11 are connected by a first connecting member so that the support frame assembly can be stacked; the front baffle 12 is detachably arranged on the front side of the support frame assembly.

[0055] Exemplarily, when the sofa is in an assembled state, the front baffle 12 abuts against the front side of the support frame assembly, and when the sofa is in a disassembled state, the front baffle 12 is separated from the support frame assembly, that is, the front baffle 12 does not abut against the front side of the support frame assembly.

[0056] When transporting the sofa provided in this embodiment, the front baffle 12 is separated from the support frame assembly, and the support frame assembly is stacked, thereby reducing the packaging volume of the sofa and reducing the transportation cost.

[0057] The number of the front baffles 12 may be one or more. For example, when the number of the front baffles is one, in order to further reduce the packaging volume of the sofa, an opening and closing seam may be provided on at least one board surface of the front baffles. For example, the material of the front baffles is sponge, the opening and closing seam is formed by cutting the front baffles, the depth of the opening and closing seam is less than the thickness of the front baffles, and the opening and closing seam extends to the thickness surface of the front baffles, which is convenient for folding and maintains the integrity of the front baffles.

[0058] It should be noted that the depth of the opening and closing seam can be selected according to the material of the front baffle, as long as it is convenient to fold the front baffle and ensure its integrity.

[0059] When the number of the front baffles 12 is greater than or equal to two, at least some of the front baffles 12 may be separately provided.

[0060] It should be understood that when the number of front baffles 12 is greater than or equal to two, the number of base frames 11 and the number of front baffles 12 may be the same or different. This embodiment will be described in detail by taking the number of base frames 11 and the number of front baffles 12 as two.

[0061] Exemplarily, the base frame 11 includes a frame 111 and a spring net 112 connected to the frame 111. The frame 111 may be rectangular in shape and include a front frame, a rear frame, a left frame, and a right frame. The mesh surface of the spring net 112 forms a support surface of the base frame 11. The cushion 10 may be placed on the support surface to provide support when the user sits on the sofa. The spring net 112, the frame 111, and the connection method thereof are all prior art and will not be described in detail herein.

[0062] In this embodiment, “the support frame assembly can be stacked” can mean folding a part of the support frame assembly, and the folded part can be stacked together with another part or not; it can also mean stacking at least two base frames 11 along their thickness direction, wherein the thickness direction of the base frame 11 refers to the direction perpendicular to its support surface. When stacking at least two base frames 11 along their thickness direction, two adjacent base frames 11 can be directly stacked, or other components such as a front baffle can be placed between the two adjacent base frames 11. Of course, the situation in which a single base frame is packaged first and then stacked also falls into the category of directly stacking two adjacent base frames 11.

[0063] It should be noted that the front side of the support frame assembly refers to the side of the support frame assembly close to the user's calf when the user sits on the sofa. The front baffle 12 is detachably arranged on the front side of the support frame assembly, which means that the front baffle 12 can be located on the front side of the support frame assembly or can be separated from the front side of the support frame assembly. When the front baffle 12 is located on the front side of the support frame assembly, the front baffle 12 can be directly connected to the support frame assembly or can be indirectly connected to the support frame assembly. The two front baffles 12 can be independent or connected together.

[0064] In some embodiments, two adjacent base frames 11 are rotatably connected via a first connection member. Specifically, the first connection member includes a first hinge member 13 , and the two adjacent base frames 11 are rotatably connected via the first hinge member 13 .

[0065] See also Figure 1 As shown, the first hinge 13 includes a mounting plate assembly, the mounting plate assembly is installed with a first hinge shaft 131 and a second hinge shaft 132, and one of the two adjacent base frames 11 is rotatably connected to the mounting plate assembly through the first hinge shaft 131, and the other base frame 11 is rotatably connected to the mounting plate assembly through the second hinge shaft 132, so that the base frame 11 can be folded to reduce the external dimensions of the support frame assembly. For example, the folded state is shown in FIG. Figure 2 As shown, Figure 2 The middle front baffle 12 has been removed from the support frame assembly. Figure 2The front bezel 12 is not shown.

[0066] For example, see Figure 1 As shown, there are two mounting plate assemblies, which are respectively located at the front and rear sides of the support frame assembly. The mounting plate assembly includes two plate portions 133, which can be arranged in parallel and spaced apart. The first hinge shaft 131 and the second hinge shaft 132 are installed between the two plate portions 133, and the axes of the first hinge shaft 131 and the second hinge shaft 132 are parallel.

[0067] To increase the support strength and stability of the support frame assembly, see Figure 1 As shown, a reinforcing rod 14 is further provided between the two mounting plate assemblies. Exemplarily, the two mounting plate assemblies are respectively welded and fixed to the two ends of the reinforcing rod 14 .

[0068] To further increase the support strength and stability of the support frame assembly, see Figure 3 As shown, a support leg 15 is further provided below the reinforcing rod 14. For example, there are two support legs 15, which are spaced apart along the length direction of the reinforcing rod 14. Figure 2 As shown, in the folded state, the two supporting legs 15 are clamped between the two base frames 11, which will not affect the external dimensions after folding.

[0069] In other embodiments, the first connecting member includes a fastening assembly, and two adjacent base frames 11 are detachably connected via the fastening assembly. When transportation is required, the two base frames 11 can be disassembled and then stacked along the thickness direction of the base frames 11, thereby also being able to reduce the overall dimensions of the support frame assembly.

[0070] Exemplarily, the fastening assembly includes fastening bolts, and two adjacent base frames 11 are detachably connected via the fastening bolts.

[0071] Exemplarily, the fastening assembly may also include a plug-in assembly, and two adjacent base frames 11 are detachably connected via the plug-in assembly. There are many forms of plug-in assemblies. For example, the plug-in assembly includes a plug rod and a sleeve, and the plug rod and the sleeve are respectively fixed to the two ends of the base frame 11, and the fixing method may be welding. When assembly is required, the plug rod on one of the base frames 11 is inserted into the sleeve of the other base frame 11. For another example, the plug-in assembly includes a first bent plate and a second bent plate, and the first bent plate and the second bent plate are respectively fixed to the two ends of the base frame 11, and the fixing method may be welding. The first bent plate is provided with a first slot, and the second bent plate is provided with a second slot. Exemplarily, the notch of the first slot faces the upper surface of the base frame 11, and the notch of the second slot faces the lower surface of the base frame 11. When assembly is required, the notch of the second slot of the second bent plate on one of the base frames 11 is aligned with the notch of the first slot of the first bent plate on the other base frame 11, and the two are plugged and connected to each other.

[0072] In one embodiment, two adjacent front baffles 12 are connected by a second connecting member. Exemplarily, the second connecting member includes a second hinge, and the two adjacent front baffles 12 are rotatably connected by the second hinge. This method can reduce the number of individual parts, reduce the possibility of part loss, and is also convenient for packaging.

[0073] Exemplarily, the structure of the second hinge is basically the same as that of the first hinge 13, and also includes a mounting plate assembly and two hinge shafts, wherein one front baffle 12 is hinged to the mounting plate assembly through one hinge shaft, and the other front baffle 12 is hinged to the mounting plate assembly through another hinge shaft, and the front baffle 12 rotates around the hinge shaft until the two front baffles 12 are in a basically parallel folded state to reduce the outer size of the support frame assembly.

[0074] In one embodiment, the sofa further comprises a first fastener, and the front baffle plate 12 is connected to the front side of the support frame assembly via the first fastener, so as to facilitate the installation and removal of the front baffle plate 12 and the support frame assembly.

[0075] For example, see Figure 5 As shown, the first fastener includes a first bolt 4, which is threadedly connected to the front baffle 12; the front side frame of the base frame 11 is provided with a first plug hole, and the first bolt 4 passes through the first plug hole to lock the front baffle 12 on the front side frame of the base frame 11.

[0076] In some embodiments, see Figure 4As shown, the first insertion hole includes a first hole portion 1111 and a second hole portion 1112, the first hole portion 1111 is connected to the second hole portion 1112, and the diameter of the first hole portion 1111 is larger than the diameter of the second hole portion 1112. The first hole portion 1111 is used for the head of the first bolt 4 to pass through, and the diameter of the second hole portion 1112 is larger than the diameter of the rod of the first bolt 4 and smaller than the diameter of the head of the first bolt 4.

[0077] During installation, install the first bolt 4 in the threaded hole of the front baffle 12 without completely tightening it, and ensure that the length of the part of the first bolt 4 located outside the front baffle 12 is greater than the thickness of the front side frame of the base frame 11; align the head of the first bolt 4 with and pass through the first hole portion 1111, and then move the front baffle 12, for example, move the front baffle 12 downward to drive the rod of the first bolt 4 to enter the second hole portion 1112, at this time, tighten the first bolt 4, because the aperture of the second hole portion 1112 is smaller than the diameter of the head of the first bolt 4, after tightening, the head of the first bolt 4 can abut against the inner side surface of the base frame 11 to prevent the front baffle 12 from separating from the base frame 11.

[0078] When the sofa is in a usable state, the front baffle 12 tends to move downward under the action of its own weight. Therefore, the first hole portion 1111 is arranged above the second hole portion 1112 to ensure that the front baffle 12 can always keep the first bolt 4 in the second hole portion 1112 under the action of its own weight, and the base frame 11 can stop the head of the first bolt 4 to prevent the front baffle 12 from separating from the base frame 11.

[0079] In some other embodiments, the first socket may also be a round hole. During installation, the threaded hole of the front baffle 12 is first aligned with the first socket, and then the first bolt 4 is passed through the first socket and threadedly connected to the threaded hole. After tightening, the front baffle 12 is fixedly connected to the support frame assembly.

[0080] It should be noted that the first fastener may also be a plug-in component or a magnetic component.

[0081] In one embodiment, see Figure 6 As shown, the sofa also includes a backrest assembly 2, which is detachably mounted on the rear side of the support frame assembly. The backrest assembly 2 includes at least two backrests 21, and two adjacent backrests 21 are connected by a third connecting member 22 so that the backrest assembly 2 can be stacked.

[0082] In this embodiment, there are two backrests 21 . Of course, the number of the backrests 21 may also be different from the number of at least one of the base frame 11 and the front baffle 12 .

[0083] It should be understood that the backrest assembly 2 is detachably mounted on the rear side of the support frame assembly, which means that the backrest 21 can be located on the rear side of the support frame assembly or can be separated from the rear side of the support frame assembly. When the backrest 21 is located on the rear side of the support frame assembly, the backrest 21 can be directly connected to the support frame assembly or can be indirectly connected to the support frame assembly.

[0084] Connecting two adjacent backrests 21 via the third connecting member 22 can enhance the overall stability of the backrest assembly 2, thereby improving the safety of the sofa.

[0085] In this embodiment, "backrest components can be stacked" can be folded over a part of the backrest component 2, and the folded part can be overlapped with another part or not; it can also be stacked and placed along the thickness direction of at least two backrests 21. When stacking and placing at least two backrests 21 along the thickness direction, two adjacent backrests 21 can be directly stacked and placed, or other components such as a front baffle can be placed between the two adjacent backrests 21. Of course, the situation where a single backrest is packaged first and then stacked and placed also falls into the category of directly stacking and placing two adjacent backrests.

[0086] In one embodiment, see Figure 7 As shown, the third connecting member 22 includes a support rod 221, a first plug-in 222 and two second plug-ins 223. The support rod 221 is connected to the support frame assembly, the first plug-in 222 is fixedly connected to the backrest 21, and the two second plug-ins 223 are respectively fixedly connected to both sides of the support rod 221, and the first plug-in 222 is plugged into the second plug-in 223.

[0087] Exemplarily, the first plug-in 222 is fixedly installed on the side of the backrest 21 by fasteners such as bolts, and the two second plug-ins 223 are fixedly installed on both sides of the support rod 221 by fasteners such as bolts. During installation, the two backrests 21 are respectively installed on both sides of the support rod 221 through the cooperation of the first plug-in 222 and the second plug-in 223 to form a whole backrest assembly, so that the front surfaces of the two backrests 21 are roughly in the same plane, and then the support rod 221 is connected to the support frame assembly. The assembled state is shown in FIG. Figure 6 shown.

[0088] In one embodiment, see Figure 7 and Figure 8 As shown, the first plug-in 222 and the second plug-in 223 both include a slot-shaped structure with two ends extending therethrough, and the extending direction of the slot-shaped structure is consistent with the extending direction of the support rod 221, so that the appearance consistency of the backrest assembly 2 after assembly can be ensured, and the phenomenon that the support rod 221 protrudes from the backrest 21 can be avoided. Exemplarily, the bottom of the slot-shaped structure is provided with a through hole for the bolt to pass through,

[0089] In some embodiments, see Figure 8 As shown, the width of the groove structure gradually decreases from one end of the groove structure away from the support frame assembly to the end close to the support frame assembly.

[0090] Exemplarily, during assembly, the first plug-in 222 is inserted into the second plug-in 223 from above the second plug-in 223, and the inclination of the groove wall of the groove structure of the first plug-in 222 is adapted to the inclination of the groove wall of the groove structure of the second plug-in 223. Since the width of the groove structure gradually decreases from the end of the groove structure far away from the support frame assembly to the end close to the support frame assembly, when inserted to a certain position, the first plug-in 222 will be supported by the two groove walls of the second plug-in 223 to ensure that the first plug-in 222 no longer moves downward. At this time, it is installed in place.

[0091] In other embodiments, the width of the groove structure gradually decreases from one end of the groove structure away from the support frame assembly to the end close to the support frame assembly; one of the first plug-in 222 and the second plug-in 223 is provided with a stopper.

[0092] Exemplarily, a stopper is provided at the bottom of the second plug-in 223, see Fig. 9 As shown, the stop portion can be a baffle 2231, which is fixedly connected to the bottom end of the groove structure of the second plug-in 223, for example, by welding, or by integral molding, that is, the bottom end of the groove structure of the second plug-in 223 is bent to form a baffle to block at least a portion of the bottom opening 61 of the second plug-in 223. The stop portion can serve as a stop for the first plug-in 222 to further prevent the first plug-in 222 from falling off from the second plug-in 223.

[0093] In other embodiments, only one of the first plug-in 222 and the second plug-in 223 may be provided with a stopper. Exemplarily, the first plug-in 222 is inserted into the second plug-in 223 from above, and a stopper is provided at the bottom of the second plug-in 223, which may be a stopper 2231. The stopper 2231 is fixedly connected to the bottom end of the groove structure of the second plug-in 223, for example, by welding, or integrally formed, that is, the bottom end of the groove structure of the second plug-in 223 is bent to form a stopper. In this case, the groove structure may be a groove of equal width, and when the first plug-in 222 is inserted into the second plug-in 223, the bottom end of the first plug-in 222 can abut against the upper surface of the stopper 2231.

[0094] Of course, a stopper may also be provided at the top end of the first plug-in 222 , and the stopper may be an outer flange provided at the top opening 61 of the first plug-in 222 .

[0095] It should be noted that the structures of the first plug-in 222 and the second plug-in 223 are not limited to the above one, as long as the functions of convenient plugging and disassembly can be achieved.

[0096] In a possible design, in order to improve the connection stability between the backrest assembly 2 and the support frame assembly, see Figure 7 As shown, the support rod 221 is provided with a limiting groove 2211, see Figure 1 As shown, the support frame assembly includes a crossbeam 16 , which can be fixedly connected to the frame 111 , and the crossbeam 16 is limited in the limiting groove 2211 .

[0097] For example, see Figure 7 As shown, the limiting groove 2211 is a groove portion with two ends through, the groove bottom of the limiting groove 2211 is welded to the bottom end of the support rod 221, and the notch of the limiting groove 2211 faces the support frame assembly. When the backrest assembly 2 is installed on the support frame assembly, the part of the crossbeam 16 of the support frame assembly corresponding to the notch of the limiting groove 2211 is limited in the limiting groove 2211. The limiting groove 2211 has a rear end, and when the user leans on the backrest 21, the rear end of the limiting groove 2211 can abut against the inner edge of the rear side of the base frame 11. For example, the rear end of the limiting groove 2211 abuts against the plate portion 133 of the mounting plate assembly located in the base frame 11.

[0098] For example, the number of the cross beams 16 can be multiple, and the multiple cross beams 16 are arranged in parallel and spaced apart. In this embodiment, see Figure 1 As shown, the setting position of the reinforcing rod 14 replaces the position of the crossbeam 16 corresponding to the limiting groove 2211 , that is, the part of the reinforcing rod 14 corresponding to the notch of the limiting groove 2211 is limited in the limiting groove 2211 .

[0099] It should be noted that when the number of backrests 21 is different from the number of base frames 11, for example, when the number of backrests 21 is three and the number of base frames 11 is two, the limiting groove 2211 can cooperate with the crossbeam 16 on the support frame assembly.

[0100] In another possible design, a socket is provided on the upper surface of the support frame assembly, and the support rod 221 is inserted into the socket.

[0101] Exemplarily, the cross beam 16 is a tubular structure, for example, the cross beam 16 is a square tube, and the socket is arranged on the upper surface of the cross beam 16. When the support rod 221 is inserted into the socket, the bottom end of the support rod 221 can abut against the inner side of the lower surface of the cross beam 16. When the user leans against the backrest 21, the rear side surface of the support rod 221 can abut against the edge of the socket to play a supporting role.

[0102] It should be noted that the third connecting member 22 may also include a third hinge, and two adjacent backrests 21 are rotatably connected via the third hinge. Exemplarily, the structure of the third hinge is substantially the same as that of the first hinge 13, and will not be described in detail here.

[0103] It should also be noted that the structural form of the third connecting member 22 is not limited to the above two types. Other forms of the third connecting member 22 can also be selected according to actual production and processing conditions, as long as the function of stacking the backrest components can be achieved.

[0104] In one embodiment, see Fig.10 As shown, the sofa further includes an armrest assembly 3 and a second fastener, and the armrest assembly 3 is detachably connected to the base frame 11 via the second fastener.

[0105] The armrest assembly 3 can adopt the structure of the existing sofa armrest. The number of the armrest assembly 3 can be one or more. For example, when the sofa is a straight sofa, the number of the armrest assembly 3 is usually two, and when the sofa is a sofa couch, the number of the armrest assembly 3 can be one.

[0106] When packaging and transportation are required, the armrest assembly 3 is disassembled from the base frame 11 and then stacked together with the backrest 21, the base frame 11 and the front baffle 12 for packaging, thereby reducing the external dimensions after packaging.

[0107] In one embodiment, the second fastener includes a second bolt 5 , which is threadedly connected to the armrest assembly 3 , and the base frame 11 is provided with a second socket, and the second bolt 5 passes through the second socket to lock the armrest assembly 3 on the base frame 11 .

[0108] In some embodiments, see Fig.11 As shown, the second insertion hole includes a third hole portion 1113 and a fourth hole portion 1114, the third hole portion 1113 is connected to the fourth hole portion 1114, and the diameter of the third hole portion 1113 is larger than the diameter of the fourth hole portion 1114. The third hole portion 1113 is used for the head of the second bolt 5 to pass through, and the hole diameter of the fourth hole portion 1114 is larger than the diameter of the rod of the second bolt 5, and smaller than the diameter of the head of the second bolt 5.

[0109] During installation, install the second bolt 5 in the threaded hole of the armrest assembly 3 without completely tightening it, and ensure that the length of the part of the second bolt 5 located outside the armrest assembly 3 is greater than the thickness of the left and right frames of the base frame 11; align the head of the second bolt 5 with and pass through the third hole portion 1113, and then move the base frame 11, for example, move the base frame 11 downward to drive the rod of the second bolt 5 to enter the fourth hole portion 1114. At this time, tighten the second bolt 5. Since the aperture of the fourth hole portion 1114 is smaller than the diameter of the head of the second bolt 5, after tightening, the head of the second bolt 5 can abut against the inner side surface of the base frame 11 to prevent the armrest assembly 3 from separating from the base frame 11.

[0110] When the user sits on the sofa, a downward force is applied to the base frame 11, so see Fig.10 and Fig.11 As shown, the fourth hole portion 1114 is arranged above the third hole portion 1113 to ensure that the second bolt 5 can always be confined in the fourth hole portion 1114, and the base frame 11 can stop the head of the second bolt 5 to prevent the armrest assembly 3 from separating from the base frame 11.

[0111] In one embodiment, the sofa further includes a third fastener, and the front baffle 12 and the armrest assembly 3 are detachably connected via the third fastener.

[0112] The manner in which the front baffle plate 12 is connected to the armrest assembly 3 via the third fastener is substantially the same as the manner in which the front baffle plate 12 is connected to the front side of the support frame assembly via the first fastener, and will not be described in detail herein.
