Description

Technical Field

[0001] This invention relates to the field of modular sofa technology, and more specifically, to a compressible modular sofa. Background Technology

[0002] With the acceleration of urbanization, residents' living spaces are showing a trend of "smaller apartments". At the same time, the "frequent moving" needs of renters and families' expectations for "multi-functional and adaptable" furniture have driven modular sofas to become one of the mainstream choices in the home furnishing market.

[0003] While traditional modular sofas feature modular assembly, the supporting frames of each module (such as single or double seats) are mostly fixed structures (e.g., solid wood frames or welded metal frames), making effective compression impossible. This results in large individual modules, which not only take up cargo space in trucks but also increase logistics costs. Furthermore, the large modules pose significant challenges for residents in high-rise buildings without elevators, requiring multiple people to move them and increasing the risk of damage due to narrow stairwells. Additionally, while some modular sofas attempt to reduce transport difficulty with detachable frames, users still need to assemble them using screwdrivers, wrenches, and other specialized tools. This cumbersome process, coupled with the risk of loose frame connections due to non-professional handling, affects the stability of subsequent use. Summary of the Invention

[0004] The purpose of this invention is to provide a compressible modular sofa to solve the problems mentioned in the background art.

[0005] A compressible modular sofa includes a two-seater sofa assembly, with single-seater sofa assemblies connected to both ends of the two-seater sofa assembly. The two ends of the two-seater sofa assembly are provided with first connecting grooves.

The second support frame assembly has two second rectangular connecting blocks connected to both sides of one end facing the single sofa assembly. Each second rectangular connecting block has a second circular hole in the middle. The inner cavity of the second support frame assembly is connected to a second fixing mechanism. One end of the second support frame assembly is connected to a second rotating assembly. The end of the second rotating assembly facing the first rotating assembly is connected to a first connecting block. The components of the second support frame assembly are the same as those of the first support frame assembly.

[0006] Preferably, the four corners of the support frame assembly are connected to first rectangular support rods, and the upper and lower ends of each adjacent first rectangular support rod are connected to first telescopic components. The top end of the first rectangular support rod connected away from the double sofa assembly is connected to a fourth telescopic rod, and the fourth telescopic rod and the first rectangular support rod form an L-shaped support frame.

[0007] Preferably, the first telescopic component includes a first rectangular frame, the inner cavity of the first rectangular frame is provided with a first rectangular groove, the inner cavity of the first rectangular groove is connected with a second rectangular support rod, the second rectangular support rod is provided with a third circular hole on both sides of one end facing the first rectangular frame, and the first rectangular frame is provided with a fourth circular hole on both sides of one end facing the second rectangular support rod, and the second rectangular support rod fits into the first rectangular groove. A rectangular support frame is formed by a plurality of first rectangular frames, a plurality of second rectangular support rods and four first rectangular support rods.

[0008] Preferably, the first fixing component has a first fixing mechanism, a first telescopic rod is connected to one end surface of the middle part of the first fixing mechanism, a second telescopic rod is connected to the end of the first telescopic rod away from the first fixing mechanism, and a first circular fixing rod is connected to both sides of the upper end of the second telescopic rod, and the initial position of the first circular fixing rod is located in the inner cavity of the first circular hole opened at the lower end of the U-shaped connecting block.

[0009] Preferably, the first fixing mechanism includes a second electric telescopic rod, the upper end of which is connected to a first vertical connecting rod, and the upper and lower ends of the first vertical connecting rod are each connected to a first horizontal telescopic rod at four positions. Each first horizontal telescopic rod is connected to a U-shaped fixing rod at the end away from the first vertical connecting rod, and the initial position of the U-shaped fixing rod is located in the cavity of the fourth circular hole opened at the lower end of the first rectangular frame, and is separated from the second rectangular support rod.

[0010] Preferably, the first rotating assembly includes a first drive motor, the output end of the first drive motor is connected to a first rotating shaft, the inner cavity of the first rotating shaft is provided with a third connecting groove, the inner cavity of the third connecting groove is connected with a connecting rod, and the surface of the connecting rod away from the first drive motor is provided with a fourth connecting groove.

[0011] Preferably, a third rectangular support frame is connected to the surface of the first rotating shaft, and a fourth rectangular support frame is slidably connected to the inner cavity of the third rectangular support frame away from the first drive motor. A third rectangular connecting rod is connected to the end of the first rotating shaft and the connecting rod away from the first telescopic component.

[0012] Preferably, the fourth connecting groove fits into the first connecting block, and the first connecting groove fits into the first rectangular connecting block.

[0013] Compared with the prior art, the advantages of this invention are: 1. In this invention, the telescopic structure of the first rectangular frame and the second rectangular support rod, combined with the vacuum compression characteristics of high-density sponge, reduces the transport volume of a single sofa module. This design not only reduces the space occupied by the truck but also lowers logistics costs. It also prevents damage to large modules during transport in stairwells, allowing for easy transport by a single person in high-rise buildings without elevators. Furthermore, the natural rebound of the high-density sponge enables "passive installation." After unpacking, the expanded sponge automatically pushes the second rectangular support rod along the first rectangular groove, forming an L-shaped support with the fourth telescopic rod, eliminating the need for manual frame adjustment. Subsequently, only the single sofa component needs to be pushed to complete the module connection, and the second electric telescopic rod can be activated via the control panel to achieve automatic locking. This effectively shortens the installation time and ensures a stable frame connection even for non-professional users.

[0014] 2. In this invention, the linkage design of sponge rebound and frame extension allows the high-density sponge to expand in sync with the movement of components such as the second rectangular support rod, connecting rod, and fourth rectangular support frame, ensuring that the rebound rhythm of the support frame and the filling material is consistent. At the same time, the guiding effect of the first rectangular groove on the second rectangular support rod and the limiting effect of the third connecting groove on the connecting rod can prevent the frame joints from jamming or the holes from misaligning.

[0015] 3. In this invention, the quick splicing and disassembly of single sofa components and double sofa components are achieved through the double fitting structure of "first rectangular connecting block and first connecting groove" and "fourth connecting groove and first connecting block". This not only allows for the combination into conventional forms such as straight sofas and L-shaped sofas, but also allows for the adjustment of module positions at any time according to changes in the living room layout. At the same time, the first drive motor enables one-click conversion between "sofa and bed". Attached Figure Description

[0018] Example: Please refer to Figure 1 , Figure 2 and Figure 3 A compressible modular sofa includes a two-seater sofa assembly 1, with single-seater sofa assemblies 2 connected to both ends of the two-seater sofa assembly 1. The two ends of the two-seater sofa assembly 1 are provided with first connecting grooves 3. The end of the single-seater sofa assembly 2 facing the two-seater sofa assembly 1 is connected to a first rectangular connecting block 4. Electric telescopic rods 5 are connected to the lower ends of one side of the single-seater sofa assembly 2 and the two-seater sofa assembly 1. The inner cavity of the single-seater sofa assembly 2 and the two-seater sofa assembly 1 is filled with high-density sponge. A control panel is connected to the surface of one end of the single-seater sofa assembly 2. Please see Figure 4 The single sofa assembly 2 includes a first support frame assembly 201. U-shaped connecting blocks 202 are connected to both sides of the end of the first support frame assembly 201 facing the double sofa assembly 1. A first circular hole 203 is opened in the middle of the U-shaped connecting block 202. A first fixing assembly 204 is connected to the inner cavity of the first support frame assembly 201. A first rotating assembly 205 is connected to one end of the first support frame assembly 201. Please see Figure 8 The double sofa assembly 1 includes a second support frame assembly 101. The two sides of the end of the second support frame assembly 101 facing the single sofa assembly 2 are connected to second rectangular connecting blocks 102. The middle part of each second rectangular connecting block 102 is provided with a second circular hole 103. The inner cavity of the second support frame assembly 101 is connected to a second fixing mechanism 104. One end of the second support frame assembly 101 is connected to a second rotating assembly 105. The end of the second rotating assembly 105 facing the first rotating assembly 205 is connected to a first connecting block 106. The components of the second support frame assembly 101 are the same as those of the first support frame assembly 201.

[0019] Specifically, the telescopic structure of the first rectangular frame 209 and the second rectangular support rod 211, combined with the vacuum compression characteristics of high-density sponge, reduces the transport volume of a single sofa module. This design not only reduces the space occupied by the truck but also lowers logistics costs. It also prevents damage to large modules during transport in stairwells, allowing a single person to handle the transport in high-rise buildings without elevators. Furthermore, the natural rebound of the high-density sponge enables "passive installation." After unpacking, the expansion of the sponge automatically pushes the second rectangular support rod 211 to extend along the first rectangular slide 210, and the fourth telescopic rod 208 forms an L-shaped support, eliminating the need for manual frame adjustment by the user. Subsequently, only the single sofa component 2 needs to be pushed to complete the module docking, and the second electric telescopic rod 218 can be activated via the control panel to achieve automatic locking. This effectively shortens the installation time and allows even non-professional users to ensure a stable frame connection.

[0020] Please see Figure 5 The four corners of the second support frame assembly 201 are connected to the first rectangular support rods 206. The upper and lower ends of each adjacent first rectangular support rod 206 are connected to the first telescopic assembly 207. The top of the first rectangular support rod 206 connected to the end away from the double sofa assembly 1 is connected to the fourth telescopic rod 208, and the fourth telescopic rod 208 and the first rectangular support rod 206 form an L-shaped support frame.

[0021] Please see Figure 5 The first telescopic component 207 includes a first rectangular frame 209. The inner cavity of the first rectangular frame 209 is provided with a first rectangular groove 210. A second rectangular support rod 211 is connected to the inner cavity of the first rectangular groove 210. The second rectangular support rod 211 has third circular holes 212 on both sides of one end facing the first rectangular frame 209. The first rectangular frame 209 has fourth circular holes 213 on both sides of one end facing the second rectangular support rod 211. The second rectangular support rod 211 fits into the first rectangular groove 210. A rectangular support frame is formed by several first rectangular frames 209, several second rectangular support rods 211 and four first rectangular support rods 206.

[0022] Please see Figure 6 The first fixing component 204 has a first fixing mechanism 214. A first telescopic rod 215 is connected to one end of the middle part of the first fixing mechanism 214. A second telescopic rod 216 is connected to the end of the first telescopic rod 215 away from the first fixing mechanism 214. A first circular fixing rod 217 is connected to both sides of the upper end of the second telescopic rod 216. The initial position of the first circular fixing rod 217 is located in the cavity of the first circular hole 203 opened at the lower end of the U-shaped connecting block 202.

[0023] Please see Figure 6 The first fixing mechanism 214 includes a second electric telescopic rod 218. The upper end of the second electric telescopic rod 218 is connected to a first vertical connecting rod 219. The upper and lower ends of the first vertical connecting rod 219 are each connected to a first horizontal telescopic rod 220 at four positions. The end of each first horizontal telescopic rod 220 away from the first vertical connecting rod 219 is connected to a U-shaped fixing rod 221. The initial position of the U-shaped fixing rod 221 is located in the cavity of the fourth circular hole 213 opened at the lower end of the first rectangular frame 209 and is separated from the second rectangular support rod 211. The components of the second fixing mechanism 104 are the same as those of the first fixing mechanism 214.

[0024] Specifically, through the linkage design of sponge rebound and frame extension, the expansion of high-density sponge synchronously drives the movement of components such as the second rectangular support rod 211, connecting rod 227, and fourth rectangular support frame 224, ensuring that the rebound rhythm of the support frame and the filling is consistent. At the same time, the guiding effect of the first rectangular groove 210 on the second rectangular support rod 211 and the limiting effect of the third connecting groove 226 on the connecting rod 227 can prevent frame joint jamming or hole misalignment.

[0025] Please see Figure 7 The first rotating assembly 205 includes a first drive motor 222. The output end of the first drive motor 222 is connected to a first rotating shaft 225. The inner cavity of the first rotating shaft 225 is provided with a third connecting groove 226. A connecting rod 227 is connected in the inner cavity of the third connecting groove 226. A fourth connecting groove 228 is provided on the surface of the end of the connecting rod 227 away from the first drive motor 222. The components of the second rotating assembly 105 are the same as those of the first rotating assembly 205, except for the third connecting groove 226.

[0026] Please see Figure 7 A third rectangular support frame 223 is connected to the surface of the first rotating shaft 225. A fourth rectangular support frame 224 is slidably connected to the inner cavity of the third rectangular support frame 223 away from the first drive motor 222. A third rectangular connecting rod 229 is connected to the end of the first rotating shaft 225 and the connecting rod 227 away from the first telescopic component 207. A third telescopic rod 230 is connected between each third rectangular connecting rod 229. The first rotating shaft 225 is installed in the inner cavity of the third rectangular support frame 223.

[0027] Specifically, through the double-fitting structure of "first rectangular connecting block 4 and first connecting groove 3" and "fourth connecting groove 228 and first connecting block 106", the single sofa component 2 and double sofa component 1 can be quickly assembled and disassembled. This not only allows for the combination into conventional forms such as straight sofas and L-shaped sofas, but also allows for the adjustment of module positions at any time according to changes in the living room layout. At the same time, the first drive motor 222 enables one-click conversion between "sofa and bed".

[0028] The fourth connecting groove 228 fits into the first connecting block 106, and the first connecting groove 3 fits into the first rectangular connecting block 4.

[0029] Specifically, traditional sofas have exposed bolts and other fixing components that can easily scratch clothing and skin. In this invention, the first fixing component 204 and the second fixing mechanism 104 are both built into the inner cavity of the support frame. The second electric telescopic rod 218 can be driven and locked by the control panel alone. There are no exposed parts on the outside. This design not only improves the overall aesthetics of the sofa, but also avoids direct contact between the user and the fixing components, reducing safety risks during use. At the same time, it reduces dust accumulation and facilitates daily cleaning and maintenance.

[0030] Working principle: The high-density sponge filling the inner cavity of the single sofa component 2 and the double sofa component 1 begins to naturally expand and rebound as the external pressure disappears. This process is the "power source" for the entire sofa to unfold, which will synchronously drive the mechanical components connected to it to move passively. When the sponge rebounds, it pushes several second rectangular support rods 211 in the two support frame assemblies to move along the first rectangular slide groove 210 in a direction away from the first rectangular frame 209, thereby gradually expanding the overall size of the support frame. This causes the first transverse telescopic rod 220, the first telescopic rod 215 and the second telescopic rod 216 in the two fixing mechanisms to extend from the compressed state to the standard sofa size. At the same time, the fourth telescopic rod 208 at the top of the first rectangular support rod 206 in the sofa assembly will extend synchronously with the expansion of the sponge, and finally form an L-shaped support structure with the first rectangular support rod 206 to provide frame support for the backrest and seat of the sofa. The sponge rebound will also cause the connecting rod 227 in the two rotating components to move along the third connecting groove 226 in a direction away from the first rotating shaft 225. When the connecting rod 227 slides, it will simultaneously drive the fourth rectangular support frame 224 to slide along the inner cavity of the third rectangular support frame 223, so that the overall length of the rotating component matches the extension size of the support frame. When the sponge has fully rebounded, the user pushes the single sofa component 2 towards the double sofa component 1 until the first rectangular connecting block 4 of the single sofa component 2 is fully embedded in the first connecting grooves 3 at both ends of the double sofa component 1, and the first connecting block 106 of the double sofa component 1 is fully embedded in the fourth connecting groove 228 of the single sofa component 2. At this time, the second rectangular connecting block 102 of the double sofa component 1 and the U-shaped connecting block 202 of the single sofa component 2 are fully fitted together, so that the first circular hole 203 of the U-shaped connecting block 202 is precisely aligned with the second circular hole 103 of the second rectangular connecting block 102. At the same time, after the support frame extends, the fourth circular hole 213 of the first rectangular frame 209 and the third circular hole 212 of the second rectangular support rod 211 will also be precisely aligned due to the restoration of size. Then, the user activates the second electric telescopic rod 218 via the control panel to extend it upwards, causing the first vertical connecting rod 219 connected to it to rise synchronously. When the first vertical connecting rod 219 rises, it pushes the U-shaped fixing rod 221, the first telescopic rod 215, the second telescopic rod 216, and the first circular fixing rod 217 to move upwards, allowing the U-shaped fixing rod 221 to pass through the aligned third circular hole 212 and the fourth circular hole 213, thereby locking the structure of the first support frame assembly 201 and the second support frame assembly 101. At the same time, the first circular fixing rod 217 passes through the aligned first circular hole 203 and the second circular hole 103, completing the inter-component locking of the single sofa assembly 2 and the double sofa assembly 1, preventing displacement after assembly. At this point, the single sofa assembly 2 and the double sofa assembly 1 are completely assembled into a whole, possessing the functions of a standard sofa. When the user needs to convert the sofa into a bed, the first drive motor 222 can be activated via the control panel, which will drive the connecting rod 227, the first rotating shaft 225, the third rectangular connecting rod 229, the third telescopic rod 230, and the first connecting block 106 to rotate. As the first connecting block 106 rotates, it will drive the second rotating assembly 105 to perform the same operation as the first rotating assembly 205, until the third rectangular connecting rod 229 is parallel to the ground. Then, the electric telescopic rod 5 can be activated via the control panel to extend until the lower end of the electric telescopic rod 5 touches the ground. At this point, the user can lie on the sofa to rest. The operation can be reversed to restore the sofa to its original form, thus ending all operations.
