Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a detachable and washable furniture. Background Technology

[0002] Sofas, as common home furnishing products, typically consist of a sofa base frame (usually a wooden frame), an elastic support structure (usually foam) fixed to the base frame, and a sofa fabric (usually leather or fabric) covering the surface of the elastic support structure. In existing technology, the installation and fixing of sofa fabric mainly employs a pneumatic nail gun fixing process. Specifically, after the elastic support structure is laid, the edges of the sofa fabric are directly nailed to the side or bottom of the sofa base frame using a pneumatic nail gun, utilizing the mechanical interlocking force of the nails to achieve a rigid connection between the fabric and the frame.

[0003] However, this traditional fixing method has significant drawbacks. First, nail fixing is an irreversible physical connection method. When daily cleaning or sofa fabric replacement is required, forced disassembly will lead to problems such as enlarged nail holes and damaged fabric edges, severely restricting the maintainability of the sofa. Second, stains accumulated over long-term use cannot be thoroughly cleaned by disassembly and washing, easily breeding bacteria and affecting hygiene. Third, repeated disassembly and reassembly will accelerate the breakage of wood fibers in the nailed parts of the sofa's bottom frame, causing a decrease in structural stability. In addition, replacing the fabric requires destroying the original fixing structure and re-nailing, which is not only cumbersome but also wastes materials, contradicting current green and environmentally friendly design concepts.

[0004] Therefore, existing sofas need to be improved to solve the problem that they cannot be disassembled for cleaning and replacement.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a detachable and washable furniture, which can effectively solve the problems of traditional furniture being non-detachable and non-washable due to the use of nail guns for fixing, resulting in hygiene hazards and material waste.

[0007] To achieve the above objectives, this utility model provides a removable and washable furniture, including a furniture base frame, an elastic support body installed and positioned on the furniture base frame, and a furniture fabric located on the top surface of the elastic support body and covering the elastic support body;

[0008] in,

[0009] The bottom frame of the furniture is provided with several protruding limiting components;

[0010] The edge of the furniture fabric extends to the limiting member and is provided with a limiting hole for the limiting member to extend into.

[0011] Optionally, the furniture base frame includes:

[0012] Peripheral side frames, which surround and form the space inside the frame;

[0013] A support partition is fixed to the inner wall of the peripheral side frame and divides the space inside the frame into a support positioning cavity for the lower part of the elastic support to be inserted, and a breathable bottom cavity located below the support positioning cavity.

[0014] Each of the limiting members is fixed to the cavity wall of the ventilated bottom cavity.

[0015] Optionally, all the limiting members are located at the same height and are evenly spaced along the cavity wall of the ventilated bottom cavity.

[0016] Optionally, the support partition is provided with a plurality of partition ventilation holes that connect the positioning cavity of the support body and the ventilation bottom cavity.

[0017] Optionally, the peripheral side frame is provided with a plurality of side frame ventilation holes that simultaneously connect the positioning cavity of the support body and the ventilation bottom cavity to the external space of the peripheral side frame.

[0018] Optionally, the edges of each side of the furniture fabric are rolled to form a rod hole;

[0019] A reinforcing rod is inserted through the through hole to abut against the limiting member.

[0020] Optionally, one end of the through hole is a sealed structure to restrict the reinforcing rod from passing through, and the other end is an open structure to allow the reinforcing rod to pass through.

[0021] Optionally, the length of the through hole is smaller than the length of the reinforcing rod.

[0022] Optionally, the limiting member is provided with a positioning groove for the reinforcing rod to be inserted.

[0023] Optionally, the number of positioning slots on the limiting member is at least two, and the positioning slots are arranged sequentially from top to bottom.

[0024] The beneficial effects of this utility model are as follows: It provides a detachable and washable furniture system that systematically solves the problems of irreversible damage, hygiene hazards, and material waste caused by traditional nail fixing processes through an innovative detachable structural design. This utility model adopts a mechanical insertion scheme of limiting components and limiting holes, changing the fabric fixing method from destructive nailing to a reversible connection. Several protruding limiting components set on the edge of the furniture's bottom frame precisely match the limiting holes pre-drilled on the edge of the fabric. During installation, simply inserting the holes into the rod completes the fixing; during disassembly, the reverse operation allows for damage-free separation.

[0025] The core advantage of this design lies in its ability to achieve non-destructive assembly and disassembly. Because the limiting component fixes the fabric through both vertical pressure and lateral restraint, the downward pressure of the elastic support keeps the fabric in close contact with the frame surface, while the limiting component only needs to resist lateral displacement, thus avoiding the damage to the wood fibers caused by repeated punctures in traditional nailing processes.

[0026] In practical application, the detachable structure significantly improves the maintainability and hygiene of furniture. Users can easily remove the entire fabric for deep machine washing, completely eliminating the problem of hard-to-clean areas in the seams of fabric or leather upholstery. Replacing fabric does not require damaging the original structure, greatly reducing operation time compared to traditional methods, and old fabrics can be completely recycled, minimizing material waste.

[0027] Therefore, the detachable and washable furniture provided by this utility model can effectively solve the problems of traditional furniture being non-detachable and non-washable due to the use of nail guns for fixing, resulting in hygiene hazards and material waste.

[0046] This utility model provides a detachable and washable furniture suitable for homes and public places. Through the non-destructive mechanical insertion design of the limiting component and the limiting hole, it solves the problems of non-detachability and hygiene hazards and material waste caused by the fixation of traditional furniture with nails.

[0047] It should be noted that the removable and washable furniture in this embodiment can be a sofa, or other products that need to be upholstered, such as upholstered bedside tables, storage stools, etc.

[0048] See Figure 1 The removable and washable furniture provided by this utility model includes a furniture base frame 1, an elastic support body 2 installed and positioned on the furniture base frame 1, and a furniture fabric 3 located on the top surface of the elastic support body 2 and covering the elastic support body 2.

[0049] in,

[0050] The furniture base frame 1 is provided with several protruding limiting members 101;

[0051] The edge of the furniture fabric 3 extends to the limiting member 101 and is provided with a limiting hole 301 for the limiting member 101 to extend into.

[0052] The removable and washable furniture provided in this embodiment systematically solves the problems of irreversible damage, hygiene hazards, and material waste caused by traditional nail gun fixing processes through an innovative detachable structural design. In the prior art, the furniture fabric 3 is directly nailed to the wooden frame by a pneumatic nail gun. This rigid connection method inevitably causes the nail holes to enlarge and the fabric to tear during disassembly, which not only limits the possibility of daily cleaning, but also makes it easier for bacteria to grow from long-term accumulated stains. Repeated disassembly and assembly will also damage the stability of the frame structure. In contrast, this utility model adopts a mechanical insertion scheme of limiting parts 101 and limiting holes 301, changing the fabric fixing method from destructive nailing to a reversible connection. Several protruding limiting parts 101 set on the edge of the furniture bottom frame 1 form a precise fit with the limiting holes 301 reserved on the edge of the fabric. During installation, the holes are simply inserted into the rod to complete the fixing. During disassembly, the opposite operation can be performed to separate the parts without damage.

[0053] The core advantage of this design lies in achieving non-destructive assembly and disassembly. Because the limiting component 101 fixes the fabric through the dual action of vertical pressure bearing and lateral limiting, the downward pressure of the elastic support 2 keeps the fabric in close contact with the frame surface, while the limiting component 101 only needs to resist lateral displacement, avoiding the damage to the wood fibers caused by repeated punctures in traditional nailing processes.

[0054] In practical application, the detachable structure significantly improves the maintainability and hygiene of furniture. Users can easily remove the entire fabric for deep machine washing, completely eliminating the problem of hard-to-clean areas in the seams of fabric or leather upholstery. Replacing fabric does not require damaging the original structure, greatly reducing operation time compared to traditional methods, and old fabrics can be completely recycled, minimizing material waste.

[0055] Specifically, by precisely matching the installation height of the limiting component 101 with the thickness of the elastic support 2, the fabric can be kept in a pre-stressed and taut state after installation. The continuous rebound force of the elastic support 2 effectively prevents wrinkles or slippage during use, maintaining the overall aesthetics and comfort of the furniture. This series of technological innovations not only breaks through the technical bottlenecks of traditional furniture in terms of maintainability and hygiene, but also deeply aligns with the concept of green environmental protection, possessing significant practical value and market competitiveness.

[0056] Therefore, the detachable and washable furniture provided by this utility model can effectively solve the problems of traditional furniture being non-detachable and non-washable due to the use of nail guns for fixing, resulting in hygiene hazards and material waste.

[0057] In this embodiment, the furniture base frame 1 includes a peripheral side frame 102 and a support partition 103. The peripheral side frame 102 surrounds and forms an internal space. The support partition 103 is fixed to the inner wall of the peripheral side frame 102 and divides the internal space into a support positioning cavity 1021 for the lower part of the elastic support 2 to be inserted, and a ventilated bottom cavity 1022 located below the support positioning cavity 1021; wherein, each of the limiting members 101 is fixed to the cavity wall of the ventilated bottom cavity 1022. That is, the limiting member 101 protrudes from the cavity wall of the ventilated bottom cavity 1022 toward the internal space of the ventilated bottom cavity 1022.

[0058] During normal use, the limiting component 101 is hidden from the consumer's view, significantly improving the neatness and aesthetics of the furniture's appearance. At the same time, the design of the ventilated bottom cavity 1022 takes into account the ventilation needs of the support positioning cavity 1021, preventing moisture accumulation and extending the service life of the furniture's internal structure.

[0059] In this embodiment, all the limiting members 101 are located at the same height and are evenly spaced along the cavity wall of the ventilated bottom cavity 1022. The limiting members 101 are equidistantly distributed along the cavity wall of the ventilated bottom cavity 1022 (optionally, the spacing is ≤30cm), thereby achieving multi-point distributed fixing, evenly dispersing the shear stress on the edge of the furniture fabric 3, and effectively avoiding fabric tearing caused by localized stress concentration. This design not only improves the connection stability between the fabric and the bottom frame but also extends the overall service life of the furniture fabric 3, while simplifying the positioning operation during installation.

[0060] Optionally, the support partition 103 is provided with a plurality of partition ventilation holes 1031 communicating with the support positioning cavity 1021 and the ventilation bottom cavity 1022. See also Figure 2 The peripheral side frame 102 is provided with a plurality of side frame ventilation holes 1023 that simultaneously connect the support positioning cavity 1021 and the ventilation bottom cavity 1022 to the external space of the peripheral side frame 102.

[0061] The ventilation holes 1031 on the support partition 103 connect the support positioning cavity 1021 and the ventilation bottom cavity 1022 to form a vertical airflow channel, which promotes ventilation and heat dissipation of the elastic support 2 (such as sponge), and prevents the elastic material from hardening or becoming moldy due to the humid and hot environment after long-term pressure, thereby maintaining the comfort and material durability of the furniture.

[0062] The side frame ventilation holes 1023 of the peripheral side frame 102 are connected to the support positioning cavity 1021 and the ventilation bottom cavity 1022 to form a horizontal ventilation path, further enhancing the air circulation inside the furniture, avoiding odors or bacterial growth caused by long-term use, improving hygiene performance, and reducing the risk of material deformation due to moisture.

[0063] See Figure 3 In this embodiment, the edges of each side of the furniture fabric 3 are rolled to form a rod hole 302; a reinforcing rod 4 for abutting against the limiting member 101 is inserted into the rod hole 302. Optionally, the reinforcing rod 4 is a metal rod or a wooden rod.

[0064] Directly using the furniture fabric 3 to bear the reaction force of the limiting member 101 can easily lead to breakage at the edge of the furniture fabric 3. By setting a through hole 302 at the edge of the furniture fabric 3 and embedding a reinforcing rod 4 (metal / wooden rod) inside, the reaction force of the limiting member 101 is transferred from the flexible fabric to the rigid rod, which significantly reduces the stress concentration at the edge of the fabric, avoids the problem of hole enlargement or edge damage caused by repeated disassembly and assembly, and at the same time ensures the uniformity of the fabric tension, thus improving the overall structural reliability.

[0065] Furthermore, one end of the rod-through hole 302 is a sealed structure to restrict the reinforcing rod 4 from passing through, and the other end is an open structure to allow the reinforcing rod 4 to pass through. The length of the rod-through hole 302 is smaller than the length of the reinforcing rod 4.

[0066] The design of the through hole 302, which is closed at one end and open at the other, allows the reinforcing rod 4 to be easily inserted and automatically stops after insertion, preventing the rod from accidentally falling off. The design of the through hole 302 being shorter than the length of the reinforcing rod 4 means that after one end of the reinforcing rod 4 is fully inserted, the other end is naturally exposed, making it easy for users to quickly apply force to pull it out by the exposed part, further simplifying the disassembly and assembly process and improving the user experience.

[0067] In this embodiment, the limiting member 101 is provided with a positioning groove 1011 for the reinforcing rod 4 to be engaged. The positioning groove 1011 on the limiting member 101 and the reinforcing rod 4 are engaged to restrict the displacement of the rod along the axial direction of the limiting member 101, avoid the displacement of the rod caused by the rebound force of the elastic support 2 or external vibration, ensure that the fabric is always in a stable and taut state, and maintain the flatness of the furniture appearance and the comfort of sitting.

[0068] In this embodiment, the number of positioning slots 1011 on the limiting member 101 is one, and the limiting member 101 is a rod-shaped structure.

[0069] In some other embodiments, see Figure 4 The limiting member 101 has at least two positioning slots 1011. In this case, the limiting member 101 is a block structure extending from top to bottom, and the positioning slots 1011 are arranged sequentially from top to bottom. The multi-level positioning slot design allows users to select different slot heights according to their needs, flexibly adjust the pretension of the fabric, and adapt to elastic supports 2 of different thicknesses or materials to achieve customized tensioning effects. This design expands the compatibility of the furniture and provides compensation and adjustment space for material deformation after long-term use, extending the product's service life.

[0070] In summary, the removable and washable furniture provided in this embodiment has the following advantages:

[0071] ① Non-destructive assembly and disassembly design: The mechanical insertion of the limiting component 101 and the limiting hole 301 replaces the fixation with gun nails, realizing non-destructive assembly and disassembly and avoiding damage to the frame and fabric caused by traditional processes.

[0072] ② Adjustable tension: The multi-level positioning slot 1011 design allows for adjustment of the fabric pretension, adapting to different support thicknesses and compensating for material deformation.

[0073] ③ Rigid reinforcement and damage prevention design: Reinforcing rods 4 are inserted along the edge of the fabric to transfer and limit the reaction force, avoiding tearing of the flexible material edge due to stress.

[0074] ④ Anti-displacement stabilizing structure: The positioning slot 1011 of the limiting part 101 is engaged with the reinforcing rod 4 to prevent the fabric from shifting due to elastic rebound or vibration.

[0075] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
