Description

Technical Field

[0001] This invention relates to the field of furniture, and in particular to a method for freely assembling furniture. Background Technology

[0002] After years of development, furniture that traditionally only has a supporting function can no longer meet the needs of users. This is because traditional supporting furniture has disadvantages such as limited functionality and large footprint, which is especially unacceptable for small houses. Therefore, existing furniture has shifted from frame-supported structures to modular structures. Users can combine and arrange furniture according to their needs, which satisfies their usage requirements and reduces the footprint of the furniture.

[0003] Existing modular furniture typically aligns identical furniture modules during assembly, but this can easily lead to misalignment during use. Therefore, to secure the modules, fasteners are usually used. However, these fasteners are often screws or rivets that can only be used once. While they ensure the modules are securely fastened, they make the assembled furniture difficult to separate. Other fasteners are similar to snap-fit ​​clips, which hold the modules together. While these clips allow for disassembly after assembly, their effectiveness is significantly reduced.

[0004] For example, in the furniture assembly structure patent with publication number CN206119721, according to the patent... Figure 1 As shown, the U-shaped clip 1 is inserted into the corresponding first insertion slot 7 and second insertion slot 8 on the first support member 2 and the second support member 3 through the first foot 4 and the second foot 5 on both sides, thereby connecting the two support members together. Although this fixing method also combines the first support member 2 and the second support member 3, when the second support member 3 is subjected to a leaning force, it will inevitably cause the U-shaped clip 1 to deflect. After the second support member 3 is subjected to repeated forces, it is easy to detach from the first support member 2. Although this fixing structure makes it easy to disassemble and assemble the first support member 2 and the second support member 3, its fixing effect is not satisfactory. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a method for freely combining furniture: by rotating and installing flip plates on two furniture modules respectively, with protrusions and mating holes spaced apart on the flip plates, and by engaging the protrusions on one flip plate with the mating holes on the other flip plate, the furniture modules are combined together; while ensuring the fixing effect, the fixing process of the furniture modules is simplified to a simple flipping and snapping process, which greatly improves the fixing efficiency of the furniture modules.

[0006] The technical solution of this invention is implemented as follows:

[0007] A method for freely combining furniture, comprising:

[0008] S1: Pre-installed furniture modules; prepare at least two furniture modules that need to be disassembled or combined;

[0009] S2: Pre-set flap; the flap is provided with a boss and a mating hole; the boss and the mating hole are arranged at intervals;

[0010] S3: Install the flip panel; a preset installation position is set on the upper end of each furniture module, and one end of the flip panel is rotated and installed at the installation position so that the flip panel can be flipped relative to the furniture module;

[0011] S4: Module Combination; Place at least two furniture modules in position and bring them close together so that the flip panels are aligned. Then, rotate the flip panels in sequence toward the adjacent furniture modules so that the protrusion on one flip panel is inserted into the mating hole on the other flip panel. Stack the two flip panels together to complete the combination of the furniture modules.

[0012] As a preferred option, there is one more step after step S4;

[0013] S5: Module disassembly; lift up the upper flap to disengage the boss of the upper flap from the mating hole of the lower flap, and the two furniture modules can be separated and moved freely; the disassembly process is fast and efficient.

[0014] Preferably, in step S3, a bearing seat is pre-set at the installation position, and one end of the flip plate is rotatably connected to the bearing seat via a rotating shaft, so that the flip plate can be flipped relative to the furniture module.

[0015] Preferably, in step S3, the flap and a rotating support plate are pre-assembled into a hinge, and the flap and the rotating support plate are rotatably connected by a rotating shaft; the rotating support plate is fixed in the installation position by fasteners, so that the hinge is pre-assembled with the furniture module; so that the furniture modules have a structural basis for mutual assembly.

[0016] Preferably, the flap is bent at the center or both ends of the side near the rotating support plate and then rolled up to form a hinge part; the cavity surrounded by the hinge part forms a hinge hole.

[0017] The rotating support plate is bent at the center or both ends of the side near the flap, thereby forming a hollow bushing at the bend; the cavity surrounded by the hollow bushing forms a circular hole;

[0018] The rotating shaft passes through the round hole and the hinge hole, hinges the hinge part on the flap and the rotating support plate, so that the flap can rotate circumferentially relative to the hollow bushing.

[0019] Preferably, a bent plate is formed near the rotating support plate of the flip plate. The bent plate extends axially along the hinge and beyond the hinge, with the extended portion forming an abutment portion and an abutment surface formed on the abutment portion. The junction between the rotating support plate and the hollow bushing extends axially along the hollow bushing and beyond the hollow bushing, with the extended portion forming a limiting portion and a limiting surface formed on the limiting portion. In step S4, after the furniture module is assembled, the abutment surface abuts against the limiting surface, thereby preventing the flip plate from rotating and making it difficult for the boss and the mating hole to separate from each other.

[0020] Preferably, the rotating support plate is a bent plate, and the bent contour of the rotating support plate is in the shape of a "Z", so that there is a joint gap between the rotating support plate and the furniture module; thereby providing installation space for the joint module.

[0021] As a preferred option, there are two more steps after step S4;

[0022] S4a: Pre-installed plug-in module; the plug-in module is higher than the furniture module, the plug-in module includes a plug-in body and a plug plate fixed to the side of the plug-in body, the plug plate is connected to the plug-in body which is higher than the furniture module; the plug plate is a bent plate with a Z-shaped bending profile; then an upper fixing plate, a middle connecting plate and a lower mating plate are formed on the plug plate, and the lower mating plate forms a gap area with the side of the plug-in body;

[0023] S4b: splicing; insert the lower mating plate into the joint gap left between the rotating support plate and the furniture module, so that the upper side of the furniture module is in the gap area, thereby keeping the joint module fixed in the lateral direction; so that the rotating support plate can provide a rotating support structure for the flip panel and also provide a joint structure for the joint module.

[0024] Preferably, the furniture module includes a frame comprising two spaced-apart long baffles and two spaced-apart short baffles; at least one rotating support plate is fixed at the middle position of the inner side of the long baffles; at least two rotating support plates are fixed at the middle position of the inner side of the short baffles; the plug-in module includes a first module and a second module, the length of the first module being greater than the length of the short baffles; when the first module is plugged into the plug-in gap on the short baffle, one end of the first module is flush with the short baffle, and the other end extends beyond the short baffle to form an overhang; at this time, the insert plate on the first module mates with the plug-in gap on the left or right side of the corresponding short baffle; the second module is the same length as the long baffles; when the second module is plugged into the plug-in gap on the long baffle, the side of the second module abuts against the overhang; at this time, the insert plate on the second module mates with the plug-in gap at the middle position of the long baffle; thus, the plug-in module can be plugged into long baffles and short baffles of different lengths.

[0025] Preferably, the two rotating support plates on the inner side of the short baffle are symmetrically arranged on both sides of the center line of the short baffle, so that the first module can be aligned with the left or right side of the short baffle.

[0026] Preferably, at least two rotating support plates fixed at the middle position of the inner side of the short baffle are integrally formed; thus, at least two rotating support plates form an integral rotating support plate group, and two or more flaps are hinged on the rotating support plate group; so that multiple flaps can be installed on a rotating support plate group at the same time, thereby shortening the time for fixing the hinge to the furniture module and enhancing the fixing effect between the furniture modules.

[0027] The principle and beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0028] This invention provides a method for freely assembling furniture. Flip plates are rotatably installed on two furniture modules, each with a protrusion and a mating hole spaced apart. The furniture modules are assembled by engaging the protrusion on one flip plate with the mating hole on the other. Compared to using screws or similar fasteners, this invention simplifies the assembly process to a simple flip-and-click process, making the assembly of furniture modules much simpler and more efficient. Furthermore, the protrusions on the flip plates, once engaged in the mating holes, effectively restrict the movement of the furniture modules in all directions on the ground, significantly improving the securing effect.

Implementation

[0043] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] In the description of this invention, the term "at least one" means one or more, unless otherwise expressly defined. The terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0046] The specific implementation methods of this invention are as follows:

[0047] like Figures 1-12 As shown, this embodiment provides a method for freely combining furniture, including:

[0048] S1: Pre-installed furniture module; such as Figure 1 As shown, at least two furniture modules that need to be disassembled or combined are prepared. The furniture module is the main supporting structure of the furniture. For example, when the furniture is a sofa, the furniture module is the sofa seat, which can serve as a support for the sofa cushion. The furniture module includes a frame 1, which includes a long baffle 11 and a short baffle 12. The long baffle 11 and the short baffle 12 are fixed to each other to form a basic polygonal support frame. Usually, to meet the shape requirements of the frame 1, the length of the long baffle 11 is set to be greater than the length of the short baffle 12. Of course, if the shape of the frame 1 has equilateral requirements, the lengths of the long baffle 11 and the short baffle 12 can be set to be the same without affecting the supporting effect of the frame 1.

[0049] S2: Pre-set flip plate 32; such as Figures 2-3As shown, the flip plate 32 is provided with a boss 321 and a mating hole 322; the boss 321 and the mating hole 322 are arranged at intervals; specifically, the outer diameter of the boss 321 is smaller than the inner diameter of the mating hole 322; and for smooth mating, the head of the boss 321 is conical, so that the head of the boss 321 has a guiding function; the function of the boss 321 and the mating hole 322 on the flip plate 32 itself can be clearly understood when two flip plates 32 are placed together. The boss 321 and the mating hole 322 are spaced apart on a single flip plate 32; however, the boss 321 and the mating hole 322 can be mated between two flip plates 32, and the boss 321 on one flip plate 32 can be flipped and locked into the mating hole 322 of the other flip plate 32; this provides a basis and idea for the free combination of furniture modules.

[0050] Furthermore, the mating hole 322 can be set through the flap 32, or it can be set as a countersunk hole with a depth not exceeding the plane of the flap 32. The shape and size of the boss 321 and the mating hole 322 can also be changed and combined at will, but the cross-sectional size of the boss 321 must always be within the range of the size of the mating hole 322. That is to say, the outer contours of the boss 321 and the mating hole 322 can be the same or different, but the boss 321 and the mating hole 322 on the two flaps 32 must be able to be inserted and mated. That is to say, the cross-sectional size of the boss 321 can surround the cross-sectional size of the mating hole 321. After the two flaps 32 are inserted and mated, they should remain fixed to each other without external interference.

[0051] Furthermore, such as Figure 11 As shown, there is a special case regarding the positional arrangement of the boss 321 and the mating hole 322: the boss 321 is fixedly connected to a hollow frustum e with openings on one or both sides. The hole inside the hollow frustum e is the same size as the mating hole 322 and is concentric in position. The connection between the hollow frustum e and the boss 321 can be integrally formed or welded. This ensures that the boss 321 and the mating hole 322 are concentric, and the distance between the boss 321 and the mating hole 322 is zero. When the two flaps 32 are engaged, the bosses 321 and the mating holes 322 on both sides of the two flaps 32 are concentric.

[0052] S3: Install the flip plate 32; a preset installation position is set on the upper end of each furniture module, and one end of the flip plate 32 is rotated and installed at the installation position so that the flip plate 32 can be flipped relative to the furniture module;

[0053] Specifically, the installation position is usually located in the middle of the side of the long baffle 11 or short baffle 12 in the frame 1. The flip plate 32 can be rotated and installed by pre-setting a bearing seat at the installation position, and one end of the flip plate 32 is rotatably connected to the bearing seat through a rotating shaft 33. This is equivalent to the flip plate 32 and the bearing seat being hinged through the rotating shaft 33, so that it can be flipped on the frame 1. In order to save installation time, the flip plate 32 and a rotating support plate 31 can also be pre-assembled into a hinge, that is, the flip plate 32 and a rotating support plate 31 are rotatably connected through the rotating shaft 33. The rotating support plate 31 is fixed in the installation position by fasteners passing through the clearance holes 312 on the rotating support plate 31, so that the hinge is pre-assembled with the furniture module, thus giving the furniture module a structural basis for flipping and assembling through the flip plate 32 on the frame 1.

[0054] Furthermore, the rotatable connection between the flap 32 and the rotating support plate 31 via the rotating shaft 33 is achieved as follows: the flap 32 is bent and shaped at the center or both ends of the side near the rotating support plate 31 and then rolled at the edge, thereby forming a hinge part 323 at the rolled edge; the cavity surrounded by the hinge part 323 forms a hinge hole a.

[0055] The rotating support plate 31 is bent at the center or both ends of the side near the flap 32, thereby forming a hollow bushing 313 at the bend; the cavity surrounded by the hollow bushing 313 forms a circular hole c.

[0056] The rotating shaft 33 passes through the circular hole c and the hinge hole a, and hinges the hinge part 323 on the flap 32 and the rotating support plate 31, so that the flap 32 can rotate circumferentially relative to the hollow bushing 313.

[0057] S4: Module combination; such as Figure 8 As shown in Figure -9, at least two furniture modules are placed in position and brought close together, so that the flip plates 32 are aligned. Then, the flip plates 32 are rotated sequentially towards the adjacent furniture modules, so that the protrusion 321 on one flip plate is inserted into the mating hole 322 on the other flip plate. The two flip plates 32 are stacked and overlapped together, completing the combination of the furniture modules. Specifically, after the protrusions 321 on the two flip plates 32 are engaged with the mating holes 322, the two flip plates 32 will not move even under external force interference in the front-back or left-right directions. This achieves the reliable connection effect required for the combination of furniture modules. Compared with the connection of clips or screws, this flip-and-lock method has the connection effect of screw fasteners and also takes into account the convenient installation operation of clip connections.

[0058] Furthermore, when the furniture modules are assembled, the boss 321 on one flip plate is inserted into the mating hole 322 on the other flip plate. At this time, the two flip plates 32 are in a horizontal state, and the boss 321 on one flip plate 32 and the mating hole 322 on the other flip plate 32 are in an unoccupied state. This means that when the two flip plates 32 are disassembled and then assembled again, even if the stacking position of the two flip plates 32 changes, it will not affect the boss 321 and the mating hole 322 from fixing the two flip plates 32 again. This improves the versatility between the two flip plates 32 and facilitates quick assembly between the two flip plates 32.

[0059] Furthermore, if the flap 32 continues to rotate, the boss 321 on one flap will inevitably disengage from the mating hole 322 on the other flap. Therefore, the flap 32 and the rotating support plate 31 are provided with a limiting structure to ensure the horizontal state of the flaps 32 after they are fixed in pairs. The limiting structure restricts the rotation of the flap 32 as follows: a bent plate 327 is formed at the position of the flap 32 near the rotating support plate 31. The bent plate 327 extends along the axial direction of the hinge portion 323 and exceeds the hinge portion 323. The excess portion forms an abutment portion 325, and an abutment surface 324 is formed on the abutment portion 325; the junction of the rotating support plate 31 and the hollow bushing 313 extends axially along the hollow bushing 313 and exceeds the hollow bushing 313, and the excess portion forms a limiting portion 315, and a limiting surface 314 is formed on the limiting portion 315; in step S4, after the furniture module is assembled, the abutment surface 324 abuts against the limiting surface 314, thereby preventing the flip plate 32 from rotating.

[0060] Furthermore, when the furniture modules are assembled together, the two flip panels 32 are in a horizontal position. This structure can also provide a supporting base for the components above the furniture modules. For example, when the furniture is a sofa, a seat cushion needs to be installed above the frame 1 in the furniture module, and the horizontal flip panels 32 can also provide a stable supporting surface for the seat cushion, making the installation of the sofa seat cushion more stable.

[0061] S4a: Pre-installed plug-in module 2; Plug-in module 2 can be understood as a support device in furniture. For example, when the furniture is a sofa, plug-in module 2 can be regarded as a sofa back or sofa armrest. In this case, plug-in module 2 needs to be fixed to frame 1 in the furniture module; Figures 6-7 As shown, the rotating support plate 31 is a bent plate, and the bent outline of the rotating support plate 31 is in the shape of a "Z", so that a joint gap 311 is left between the rotating support plate 31 and the furniture module; thereby providing installation space for the joint module 2.

[0062] Specifically, the plug-in module 2 is higher than the furniture module. The plug-in module 2 includes a plug-in body 22 and a plug plate 21 fixed to the side of the plug-in body 22. The plug plate 21 is connected to the plug-in body 22, which is higher than the furniture module. The plug plate 21 is a bent plate with a Z-shaped bending profile. An upper fixing plate 213, a middle connecting plate 214, and a lower mating plate 215 are formed on the plug plate 21. The lower mating plate 215 and the side of the plug-in body 22 form a gap area 211, thereby leaving space for the fixing of the plug-in module 2 and the frame 1.

[0063] Furthermore, the upper fixing plate 213 above the plug-in plate 21 and the vertical plate 22 are fixed together in the following way: the plug-in plate 21 is provided with mounting holes 212, and the vertical plate 22 is provided with screw holes. The threaded fastener passes through the mounting holes 212 and is screwed into the screw holes on the vertical plate 22 to fix the plug-in plate 21 and the vertical plate 22 together.

[0064] S4b: Splicing; Insert the lower mating plate 215 into the insertion gap 311 left between the rotating support plate 31 and the furniture module, so that the upper side of the furniture module is in the gap area 211, thereby keeping the insertion module 2 fixed in the lateral direction; Specifically, the rotating support plate 31 is not only a support for the rotation of the flip plate 32, but also a fixed carrier for the insertion module 2; The rotating support plate 31 is a bent plate, and the bent outline is in the shape of a "Z", thus forming an insertion gap 311 in the middle of the rotating support plate 31; When the rotating support plate 31 is fixed on the frame 1, the insertion gap 311 and the side of the frame 1 limit the insertion plate 31 in all directions except the vertical direction, so that the insertion module 2 is fixed at the same time, and can be inserted and pulled out of the insertion gap 311 at any time to keep the insertion module 2 and the furniture module in an integrated or separate state.

[0065] Furthermore, the plug-in module 2 includes a first module 2b and a second module 2a. The first module 2b and the second module 2a have the same structural configuration, the difference being that the first module 2b plugs into the short baffle 12, and the second module plugs into the long baffle 11. For the long baffle 11 and the short baffle 12, the plug-in module 2 is a universal component. The length of the first module 2b is greater than the length of the short baffle 12. The two rotating support plates 31 on the inner side of the short baffle 12 are symmetrically arranged on both sides of the center line of the short baffle 12. When the first module 2b is plugged into the plug-in gap 311 on the short baffle 12, one end of the first module 2b is flush with the short baffle 12, and the other end extends beyond the short baffle 12 to form an overhanging part s. At this time, the plug plate 21 on the first module 2b and the corresponding... The short baffle 12 at the position has a joint gap 311 on the left or right side; the second module 2a is the same length as the long baffle 11. When the second module 2a is inserted into the joint gap 311 on the long baffle 11, the side of the second module 2a abuts against the protruding part s. At this time, the insertion plate 21 on the second module 2a is engaged with the joint gap 311 in the middle position of the long baffle 11. This allows at least one corner of the frame 1 to be surrounded by the insertion module 2. Since at least two rotating support plates 31 are provided on the short baffle 12, the first module 2b can have at least two insertion points in the left and right directions. Without changing the position of the insertion plate 21 on the insertion module 2, the insertion module 2 can be inserted into and engaged with long baffles 11 and short baffles 12 of different lengths.

[0066] Furthermore, such as Figure 5 As shown, in order to speed up the processing and installation of the rotating support plate 31, at least two rotating support plates 31 fixed at the middle position of the inner side of the short baffle 12 can be integrally formed; thus, at least two rotating support plates 31 form an integral rotating support plate group 41; the rotating support plate group 41 and the at least two rotating flaps 32 above it form a parallel hinge 4; during installation, multiple flaps and rotating support plate group 41 only need to be pre-installed to install the hinge 3 onto the furniture module 1, which shortens the installation time of the hinge 3 and the furniture module 1 and improves the installation efficiency of the hinge 3 and the furniture module 1.

[0067] S5: Module disassembly; lift up the upper flap 32 so that the boss 321 of the upper flap 32 disengages from the mating hole 322 of the lower flap, and the two furniture modules can move freely apart; specifically, the flap 32 can determine the connection state between the two furniture modules by flipping it so that the boss 321 and the mating hole 322 are engaged and disengaged; making the combination and separation of furniture modules equally simple and quick.

[0068] Furthermore, such as Figure 1 , Figure 4As shown, when the two furniture modules are in a separated state, the flip plate 32 forms a rotation limit with the rotating support plate 31 through its own structure; a corner edge 326 is formed at the bending position of the flip plate 32, and the corner edge 326 abuts against the rotating support plate 31, preventing the flip plate 32 from rotating and making the limiting angle b formed by the flip plate 32 and the plane of the rotating support plate 31 less than 90°; thus, the flip plate 32 is located inside the lower part of the frame 1, so that the furniture modules in the separated state can also smoothly install parts such as cushions, thereby avoiding interference between the flip plate 32 and them; the limiting angle b is also the toggle angle that leaves a toggle gap. When a finger is placed in the toggle angle and the flip plate 32 is toggleed, the hinge module can quickly enter the combined state.

[0069] like Figure 1 As shown, in order to enrich the functionality of the furniture, a functional module 5 can be connected to the furniture module using hinge 3 or parallel hinge 4; for example, when the furniture is a sofa, the functional module 5 can be regarded as a sofa bed, so that the sofa combination has both sitting and reclining functions, further enriching the functionality and practicality of the sofa.

[0070] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
