Technical Field
[0001] This application relates to the field of furniture technology, and more particularly to a splicing frame and furniture. Background Technology
[0002] Upholstered furniture (beds, sofas, etc.) is a type of furniture made primarily of soft materials. Since the components of upholstered furniture (frame, cushions, backrests, etc.) are easily damaged, existing technologies have designed frames that can be detachably connected to other components, allowing for timely replacement of damaged components.
[0003] In the production process of the frame in the above-mentioned prior art, it is necessary to first go through processes such as mold design, metal melting, and die casting to produce individual parts, and then assemble the various parts with different structures into a frame. Since the production and assembly processes of the parts are relatively complex, the production of the frame and furniture is difficult. Utility Model Content

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] This application provides a splicing frame 10.
[0030] Please refer to Figures 1 to 8 The splicing frame 10 includes a frame 100 and a frame sleeve 200 fitted over the frame 100. The frame 100 includes a first support component 2 and a second support component 3. Both the first support component 2 and the second support component 3 include two mounting plates and a plurality of connecting plates disposed between the two mounting plates. Each mounting plate includes a connecting portion. The first support component 2 is arranged along a first direction to form a first support surface of the splicing frame, and the mounting plate of the second support component 3 is arranged along a second direction to form a second support surface of the splicing frame. The first direction is perpendicular to the second direction. The first support component 2 and the second support component 3 are detachably connected. The mounting plates are used to mount target components, and the splicing frame is used to assemble furniture with the target components.
[0031] Please refer to the above. Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of frame 100. Figure 2 This is an assembly diagram of frame 100. Both the first support component 2 and the second support component 3 of frame 100 include multiple connecting plates, each positioned between two mounting plates. That is, the components constituting the first support component 2 and the second support component 3 are all plate-like structures, preferably square plates. During production, the mounting plates and connecting plates only require cutting processes. Compared to the multiple processing techniques required for the production of parts in the existing frame 100, the processing is simpler and easier to manufacture. In an optional embodiment, the first support component 2 and the second support component 3 are made of the same material, such as eco-board, particleboard, plywood, blockboard, fiberboard, etc. Using these materials avoids the melting and die-casting processes of metal materials, further reducing energy and resource consumption during component production and lowering production difficulty.
[0032] The first support component 2 is arranged along a first direction to form a first support surface of the splicing frame, and the second support component 3 is arranged along a second direction to form a second support surface of the splicing frame. Figure 1In the illustrated embodiment, the first direction is the front-to-back direction, and the second direction is the up-and-down direction. Both the first and second support surfaces can be used to support other components, and the splicing frame 10 can be combined with these other components to form furniture. A unified assembly method reduces assembly difficulty compared to using different assembly methods for different parts. Optionally, for the above assembly method, mounting protrusions can be provided on the mounting plate, and mounting grooves can be opened on the connecting plates corresponding to the first support component 2 and the second support component 3. Assembly is achieved by inserting the mounting protrusions and mounting grooves. Alternatively, external connectors such as screws, eccentric parts, Lock & Lock connectors, Lamino connectors, and nail guns can be used to connect the connecting plates of the first support component 2 and the second support component 3 to their respective mounting plates. Since the first support component 2 and the second support component 3 are both simple-structured boards, the positioning method is relatively simple, and the assembly difficulty is low. The inward-facing side of the mounting plate is used to install the connecting plate of the first support component 2 or the second support component 3, and the outward-facing side of the mounting plate is used to install external target components to assemble the furniture with the splicing frame 10.
[0033] like Figure 3 As shown, after the first support component 2 and the second support component 3 are assembled to form the frame 100, multiple frames 100 can be combined as needed. The connection between frames 100 can be achieved through mounting plates and external connectors. For the spliced frame 10 formed by combining multiple frames 100, the two outermost mounting plates 1 are used to install the target components. Figure 4 As shown, a frame sleeve 200 is fitted over at least one frame 100 to form a splicing frame 10 according to an embodiment of this application. The frame sleeve 200 is made of a flexible material, including but not limited to fabric, silicone, etc. The frame sleeve 200 can provide users with a more comfortable touch and can enhance the appearance of the splicing frame 10.
[0034] In this embodiment, the first support component 2 and the second support component 3 are composed of plate-shaped connecting plates. It can be understood that each component of the frame 100 is a simple plate material. In the production process, only cutting technology is needed to complete the processing of each component. Compared with the complex process of processing multiple components with different structures in the prior art, the production process of the frame 100 in this embodiment is simpler and reduces the production difficulty, that is, reduces the production difficulty of furniture.
[0035] Optionally, each of the connecting parts has at least one mounting hole for mounting the target component.
[0036] like Figure 1As shown, each mounting plate has mounting holes for mounting the target component. At least one mounting hole 13 is provided on the connecting portion 4 of the mounting plate corresponding to the first support assembly and the connecting portion 1 of the mounting plate corresponding to the second support assembly. Figure 1 In the illustrated embodiment, two mounting holes are formed on the connecting portion 4 of the mounting plate corresponding to the supporting component, and two mounting holes are formed on the connecting portion 1 of the mounting plate corresponding to the second supporting component. Different mounting holes can be selected from multiple mounting holes as needed to install target components of different shapes, improving the versatility of the frame 100 in this embodiment and reducing the difficulty of subsequently developing compatible target components. Figure 4 As shown, a through hole 201 can be provided on the frame sleeve 200 at the position corresponding to the mounting hole of the mounting plate 1, so that the connector can pass through the frame sleeve 200 and be inserted into the mounting hole.
[0037] Optionally, the first supporting component includes a first mounting plate, a second mounting plate, a first connecting plate 21, a second connecting plate 22, and a third connecting plate 23. The surface of the first connecting plate 21 is disposed along the first direction. The second connecting plate 22 and the third connecting plate 23 are respectively disposed on opposite sides of the first connecting plate 21 in the second direction. The first connecting plate 21 is detachably connected to the connecting portions of the first mounting plate and the second mounting plate on opposite sides in the third direction. The second connecting plate 22 and the third connecting plate 23 are detachably connected to the connecting portions of the first mounting plate and the second mounting plate on opposite sides in the third direction, and the second connecting plate 22 and the third connecting plate 23 abut against the first connecting plate 21. The surface of the first connecting plate 21 is the first supporting surface. The first direction is perpendicular to the second direction, the first direction is perpendicular to the third direction, and the second direction is perpendicular to the third direction.
[0038] Please refer to the above. Figure 1 and Figure 3 Third party is Figure 1 , Figure 3 The left and right directions in the illustrated embodiment. The surface of the first connecting plate 21 is disposed along the first direction, and the second connecting plate 22 is disposed along the second direction. It can be understood that the surface of the first connecting plate 21 is disposed along... Figure 1 As shown, the second connecting plate 22 and the third connecting plate 23 are arranged in a horizontal direction, with their surfaces along... Figure 1As shown in the vertical arrangement, the first connecting plate 21, the second connecting plate 22, and the third connecting plate 23 are respectively connected to two connecting parts on their left and right sides. The second connecting plate 22 and the third connecting plate 23 are located at the lower ends of the first connecting plate 21 and abut against it. It can be understood that the second connecting plate 22 and the third connecting plate 23 can provide support for the first connecting plate 21 to a certain extent. The upper-facing surface of the first connecting plate 21 is the first supporting surface of the frame 100. In this embodiment, the structure of the first connecting plate 21, the second connecting plate 22, and the third connecting plate, as well as the assembly method with the two mounting plates, are relatively simple, which can reduce the production difficulty of the frame 100.
[0039] Optionally, the second supporting component 3 includes a third mounting plate, a fourth mounting plate, a fourth connecting plate 31, a fifth connecting plate 32, and a sixth connecting plate 33. The surfaces of the fourth connecting plate 31 and the fifth connecting plate 32 are both arranged along the second direction. The fourth connecting plate 31 is detachably connected to the connecting portions of the third mounting plate and the fourth mounting plate on its opposite sides in the third direction. The fifth connecting plate 32 is detachably connected to the connecting portions of the third mounting plate and the fourth mounting plate on its opposite sides in the third direction. The fourth connecting plate 31 and the fifth connecting plate 32 have a gap along the first direction. The surface of the fourth connecting plate 31 facing the direction of the first connecting plate is the second supporting surface. The surface of the sixth connecting plate 33 is arranged along the first direction, and the opposite sides of the sixth connecting plate 33 abut against the fourth connecting plate 31 and the fifth connecting plate 32. The sixth connecting plate 33 includes a connecting portion, and the connecting portion of the sixth connecting plate 33 is detachably connected to the first connecting plate.
[0040] The surfaces of the fourth connecting plate 31 and the fifth connecting plate 32 are arranged along the second direction. Understandably, the surfaces of the fourth connecting plate 31 and the fifth connecting plate 32 are parallel. The left and right sides of the fourth connecting plate 31 and the fifth connecting plate 32 are respectively connected to two connecting parts 12. The fourth connecting plate 31 is located in front of the fifth connecting plate 32. There is a gap between the fourth connecting plate 31 and the fifth connecting plate 32, that is, the area between the fourth connecting plate 31 and the fifth connecting plate 32 included in the frame 100 is not solid, which reduces the overall weight of the frame 100. The front-facing surface of the fourth connecting plate 31 is the second supporting surface of the frame 100. The surface of the sixth connecting plate 33 is arranged along the first direction, and the opposite sides of the sixth connecting plate 33 abut against the fourth connecting plate 31 and the fifth connecting plate 32 respectively. The sixth connecting plate 33 includes a connecting part, and the connecting part of the sixth connecting plate 33 is detachably connected to the first connecting plate 21. It can be understood that the sixth connecting plate 33 serves as the base plate of the second support component, and a connector is provided on the base plate for detachable connection with the aforementioned first support component. In some optional embodiments, the aforementioned second support component is also disposed in the middle of the sixth connecting plate, perpendicular to the surface of the sixth connecting plate, and abutting against the fourth and fifth connecting plates. There can be three connecting parts, including two connecting parts symmetrically arranged on both sides of the sixth connecting plate, and a connecting part directly below the central connecting plate. In this embodiment, the structure of the fourth connecting plate 31, the fifth connecting plate 32, and the sixth connecting plate, as well as the assembly method with the mounting plate 1, are relatively simple, which can reduce the production difficulty of the frame 100.
[0041] Optionally, the second support assembly includes a seventh connecting plate and an eighth connecting plate. The surface of the seventh connecting plate is disposed along the second direction, and the surface of the eighth connecting plate is inclined relative to the second direction. The connecting portion of the second support assembly includes a first connecting segment and a second connecting segment connected to each other. The thickness of the second connecting segment in the first direction gradually decreases in a direction away from the first connecting segment, so as to form an inclined surface on the second connecting segment that is consistent with the inclined direction of the surface of the second support. The eighth connecting plate is detachably connected to the connecting portions of the third mounting plate and the fourth mounting plate on opposite sides in the third direction, and the seventh connecting plate is detachably connected to the second connecting segments of the connecting portions of the two third mounting plates and the fourth mounting plates on opposite sides in the third direction. The eighth connecting plate and the seventh connecting plate have a gap along the first direction, and the surface of the seventh connecting plate facing the direction of the first connecting plate is the second support surface.
[0042] Compared to the fourth connecting plate 31 and the fifth connecting plate 32 being arranged parallel to each other in the plate surface direction, in this embodiment, as... Figure 1 and Figure 3As shown, the surface of the seventh connecting plate 31 is inclined. Compared with the vertical orientation of the fourth connecting plate 31 in the above embodiment, the inclined surface can provide a larger support area for external components. Meanwhile, as... Figure 3 As shown, in order to match the seventh connecting plate 31, the thickness of the connecting part of the mounting plate is reduced in the front-to-back direction along the up-down direction to form an inclined surface that is consistent with the inclined direction of the seventh connecting plate 31. This ensures that when the seventh connecting plate 31 is installed on the mounting plate 4, there will be no excess material protruding from the mounting plate 4, which would cause inconvenience in use.
[0043] Optionally, the mounting plate of the first support component also has two clearance slots, which are located at two corners away from the second support component. Figure 4 As shown, the mounting plate has a clearance groove 14, which can accommodate protruding structures such as wall skirting boards when the frame 100 is against the wall, so that the rear side of the frame 100 is tightly attached and receives stable support.
[0044] This application also provides a type of furniture, which includes a fixed frame, armrests, seat cushion, backrest, and the aforementioned splicing frame. (See reference...) Figure 6 The two fixing frames are installed on both sides of the splicing frame, and the two armrests are respectively installed on the two fixing frames. The first support surface and the second support surface of the splicing frame support the seat cushion and the backrest. Therefore, at least all the technical effects of the above embodiments can be achieved, which will not be described in detail here.
[0045] Optionally, both the seat cushion 30 and the backrest cushion 40 are composed of flexible filling material and a protective sleeve covering the flexible filling material. The protective sleeve uses a zipper to enclose the flexible filling material and ensure overall stability. Preferably, the flexible filling material consists of at least one layer of support material, including individually pocketed springs, plant fiber pads, and composite material pads, which can improve the user experience. In one embodiment, the armrest 20 can also be composed of flexible filling material and a protective sleeve covering the flexible filling material. The main difference between the seat cushion 30, the backrest cushion 40, and the armrest 20 lies in their shapes.
[0046] Optionally, a first receiving space 50 is formed between the two armrests 20 and the splicing frame 10, and the seat cushion 30 is disposed within the first receiving space 50, with the first supporting surface supporting the seat cushion 30. For example... Figure 6 and Figure 7 As shown, in Figure 7 In the illustrated embodiment, the surface of the handrail 20 that contacts the mounting plate 1 has holes corresponding to the mounting holes 13 for mounting the handrail 20. Figure 6As shown, after the armrest 20 is installed onto the splicing frame 10, a first accommodating space 50 is formed between the armrest 20 and the splicing frame 10 for accommodating the seat cushion 30. In one embodiment, the size of the seat cushion 30 is smaller than the first accommodating space 50 and smaller than the first supporting surface, which can support the seat cushion 30. In another embodiment, the length of the seat cushion 30 in the third direction is slightly greater than the length of the first accommodating space 50 in the third direction. The seat cushion 30 is disposed within the first accommodating space 50. Since both the armrests 20 and the seat cushion 30 are elastic, the armrests 20 on both sides can clamp the seat cushion 30, making the installation of the seat cushion 30 more secure. Figure 8 As shown, the armrests 20 have different shapes and can be combined with the splicing frame 10 to form different furniture.
[0047] Optionally, a second receiving space 60 is formed between the two armrests 20, the splicing frame 10, and the seat cushion 30. A backrest 40 is disposed within the second receiving space 60, and the first and second supporting surfaces jointly support the backrest 40. Please see further details. Figure 6 A second accommodating space 60 is formed between the armrest 20, the splicing frame 10, and the seat cushion 30, and the backrest 40 is disposed within the second accommodating space 60. In one embodiment, the size of the backrest 40 or a combination of multiple backrests 40 is smaller than the second accommodating space 60; in another embodiment, the length of the seat cushion 30 (or the combination of backrests 40) in the third direction is slightly greater than the length of the second accommodating space 60 in the third direction. The seat cushion 30 is disposed within the second accommodating space 60. Since both the armrests 20 and the backrest 40 on both sides are elastic, the armrests 20 on both sides can clamp the backrest 40, making the installation of the backrest 40 more secure.
[0048] Optionally, the above-mentioned connecting part can be adopted as follows: Figure 10 and Figure 11 The connector shown works on the principle of hole size difference and sliding locking mechanism. The connector as a whole can be composed of parts adapted to different hole diameters. In use, the corresponding connector is first inserted into the large hole end of the component. Since the diameter of the large hole is larger than the initial passage size of the connector, it can be inserted smoothly. Then, the connector is slid along the predetermined direction. When it reaches the small hole end, the connector, through its own structure (such as elastic deformation, shape fitting, or limiting design), prevents it from sliding or disengaging at the small hole position, thereby achieving locking.
[0049] This design allows for easy positioning through the large holes during installation, followed by tightening by sliding to the smaller holes, ensuring a secure connection. It is suitable for scenarios requiring convenient installation and reliable fixation, such as connecting components of furniture frames. It effectively prevents the structure from loosening during use, balancing installation convenience with connection stability.
[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
