Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and in particular to a compressible sofa. Background Technology

[0002] A sofa is a multi-seat chair with cushions, typically with a metal or wood frame, a backrest made of springs or thick foam, and armrests on both sides; it falls under the category of upholstered furniture. Currently, to facilitate transportation and storage, sofas are often designed as modular units. However, these sofas are often large and heavy, making them extremely inconvenient to move for consumers living in buildings without elevators or with small elevator spaces.

[0003] With the booming development of the global e-commerce industry, sofas are increasingly being delivered to customers or merchants via logistics. However, traditional sofas, due to their built-in metal or wooden frames, have limited capacity per shipping container, resulting in logistics costs accounting for a large, even excessive, proportion of the total product cost, thus driving up the final selling price. In particular, the limited capacity per container makes it difficult to fully meet market demand. Currently, compressible sofas have appeared on the market, but most of these are supported by foam, resulting in a poor sitting experience. Therefore, a compressible sofa that can improve the user experience is urgently needed. Utility Model Content

[0004] In view of the above-mentioned defects, the purpose of this utility model is to propose a compressible sofa to solve the problem of poor seating experience of existing compressible sofas.

[0005] To achieve this objective, the present invention adopts the following technical solution: a compressible sofa, comprising: a bottom mounting part, a sofa part, and an elastic element;

[0006] The bottom mounting portion has a mounting groove, and a protrusion is provided in the mounting groove. The protrusion protrudes upward from the opening of the mounting groove, and the protrusion divides the mounting groove into multiple mounting cavities of the same area.

[0007] The elastic element is placed inside the mounting cavity, and the end of the elastic element is flush with the opening of the mounting groove.

[0008] The sofa part is disposed on the bottom mounting part, and the sofa part has a mounting hole, the inner contour of the mounting hole being adapted to the outer contour of the protrusion;

[0009] When the sofa part is installed with the bottom mounting part, the protrusion is inserted into the mounting hole, and the free end of the protrusion is flush with the end face of the sofa part;

[0010] The bottom mounting part and the sofa part are made of hard foam.

[0011] Preferably, the hardness of the rigid sponge is ≥56°.

[0012] Preferably, the elastic element includes a base plate and multiple sets of spring arrays evenly distributed on the base plate.

[0013] Preferably, the spacing between the spring arrays is equal to the diameter of a single spring, wherein one end of the base plate is the near end, the opposite end of the near end is the far end, the distance H1 between the near end and the nearest spring array is less than the diameter of a single spring, and the distance H2 between the far end and the nearest spring array is greater than or equal to the diameter of a single spring.

[0014] Preferably, the bottom mounting portion includes a base and a plurality of upright bases surrounding the edge of the base and connected end to end, the base and the bases together forming the mounting groove, and the protrusion is fixed to the center of the base.

[0015] Preferably, the base includes a first base and a second base arranged symmetrically in pairs; wherein the height of the first base is higher than the height of the second base.

[0031] like Figures 1-4As shown, a compressible sofa includes: a bottom mounting part 1, a sofa part 2, and an elastic element 3;

[0032] The bottom mounting part 1 has a mounting groove 11, and a protrusion 12 is provided in the mounting groove 11. The protrusion 12 protrudes upward from the groove opening of the mounting groove 11, and the protrusion 12 divides the mounting groove 11 into multiple mounting cavities 111 with the same area.

[0033] The elastic element 3 is placed in the mounting cavity 111, and the end of the elastic element 3 is flush with the opening of the mounting groove 11.

[0034] The sofa part 2 is disposed on the bottom mounting part 1, and the sofa part 2 has a mounting hole 211, the inner contour of the mounting hole 211 being adapted to the outer contour of the protrusion 12;

[0035] When the sofa part 2 is installed with the bottom mounting part 1, the protrusion 12 is inserted into the mounting hole 211, and the free end of the protrusion 12 is flush with the end face of the sofa part 2.

[0036] The bottom mounting part 1 and the sofa part 2 are made of hard foam.

[0037] The bottom mounting part 1 and the sofa part 2 are made of rigid sponge. After being put into a compression bag, the bottom mounting part 1 and the sofa part 2 can be compressed by vacuuming. The compressed volume can be reduced to 30% of the original volume, which greatly facilitates the transportation and handling of the sofa.

[0038] After receiving the compression bag, the customer can open it to decompress it, obtaining the bottom mounting part 1 and the sofa part 2. In this invention, a mounting groove 11 is provided in the bottom mounting part 1, and an elastic element 3 can be stored in the mounting cavity 111. The sofa part 2 is then placed on top of the bottom mounting part 1 to complete the sofa assembly. To prevent the sofa part 2 from shifting forward or backward, a mounting hole 211 is also provided in the sofa part 2. During installation, the protrusion 12 located in the bottom mounting part 1 is inserted into the mounting hole 211, limiting the sofa part 2 and preventing it from moving. Furthermore, the insertion method greatly improves the convenience of installation.

[0039] Furthermore, because the sofa incorporates elastic elements 3, when a person sits down, these elements deform first, providing a comfortable initial sinking sensation; as pressure continues to increase, the firm foam provides solid and reliable final support. This progressive support experience, from soft to firm, perfectly simulates the seating feel of traditional high-end sofas, completely resolving the drawback of pure foam sofas having a "poor sitting experience." This improves the user experience of compressed sofas.

[0040] Preferably, the hardness of the rigid sponge is ≥56°.

[0041] Only when the hardness of the rigid foam is greater than 56° can the support strength of the bottom mounting part 1 for the user be guaranteed when the sofa is in use.

[0042] Preferably, the elastic element 3 includes a base plate 31 and multiple sets of spring arrays 32 equidistantly distributed on the base plate 31.

[0043] By integrating the dispersed springs into a stable and reliable standardized spring array 32, the elastic element 3 can be directly placed into the mounting cavity 111 during installation, improving installation efficiency. Furthermore, the equidistant distribution of the multiple spring arrays 32 ensures a high degree of consistency in comfort.

[0044] Preferably, the spacing between the spring arrays 32 is equal to the diameter of a single spring, wherein one end of the base plate 31 is the near end 311, and the opposite end of the near end 311 is the far end 312. The distance H1 between the near end 311 and the nearest spring array 32 is less than the diameter of a single spring, and the distance H2 between the far end 312 and the nearest spring array 32 is greater than or equal to the diameter of a single spring.

[0045] During transportation, one elastic element 3 can be inverted onto another elastic element 3. Since the spacing between the spring arrays 32 is equal to the diameter of a single spring, the spring arrays 32 of different elastic elements 3 can be staggered when inverted. Furthermore, the base plate 31 has a remote end 312, which ensures that each spring array 32 is positioned between the two base plates 31 when inverted. Then, the two elastic elements 3 are placed in a rigid compression bag for physical compression, reducing the volume of the elastic elements 3 during transportation.

[0046] Preferably, the bottom mounting part 1 includes a base and a plurality of upright bases 13 that surround the edge of the base and are connected end to end. The base and the bases 13 together form the mounting groove 11, and the protrusion 12 is fixed to the center of the base.

[0047] Preferably, the base 13 includes a first base 131 and a second base 132 arranged symmetrically in pairs; wherein the height of the first base 131 is higher than the height of the second base 132.

[0048] The first base 131 is located on the left and right sides of the base, thus forming the structure of armrests, giving the sofa lateral support and bringing a better user experience.

[0049] Preferably, the sofa part 2 includes a seat cushion 21 and a backrest 22 disposed on the edge of the seat cushion 21, and the seat cushion 21 has the mounting hole 211 in the middle.

[0050] In this utility model, the sofa part 2 is also provided with a backrest 22, which is connected to the back of the seat cushion 21 to form a backrest-like structure. When the user sits on the seat cushion 21, the back can be supported by the backrest 22, providing support for the user's back and giving the user a better user experience.

[0051] Preferably, when the sofa part 2 is installed with the bottom mounting part 1, the seat cushion 21 is supported by the second base 132 and the elastic member 3.

[0052] Preferably, the bottom mounting part 1 and the sofa part 2 are integrally formed.

[0053] When compressed, the one-piece molded bottom mounting part 1 and sofa part 2 can be compressed into two independent parts. This can help merchants sort and ship goods during transportation, improving sorting and shipping efficiency. Customers only need to install the two independent parts, which also improves the customer's installation efficiency.
