Description

Technical Field

[0001] This utility model relates to the field of furniture design technology, and in particular to an unfoldable fabric sofa. Background Technology

[0002] Fabric sofas are sofas with fabric as the main surface material. They come in a variety of styles and can match various home decoration styles, such as minimalist, pastoral, and Nordic styles, adding a warm atmosphere to the home environment.

[0003] Fabric sofas are soft and comfortable to the touch, skin-friendly, and provide a pleasant sitting or lying experience. Moreover, they have a wide price range, from a few hundred yuan to tens of thousands of yuan, allowing consumers to choose according to their budget.

[0004] However, traditional unfoldable fabric sofas mostly use a connected structure. Due to the narrow space and complex structure at the bottom of the unfolded area, dirt and grime easily accumulate, making it difficult for common cleaning tools such as brooms and vacuum cleaners to reach inside, making cleaning extremely difficult.

[0005] For example, when dust, hair, food scraps and other debris accumulate at the bottom, users often have to lift the sofa to clean it, which is a tedious and laborious process. If they don't want to go through all that trouble, they can only ignore the dirt and let it breed bacteria, affecting the hygiene and health of their home environment. Utility Model Content

[0006] This utility model discloses an unfoldable fabric sofa, aiming to solve the technical problem that most fabric sofas adopt a connected structure, and the bottom of the unfolded area is prone to accumulating dirt and grime due to the narrow space and complex structure, making it difficult for commonly used cleaning tools such as brooms and vacuum cleaners to reach it, thus making cleaning extremely difficult.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An unfoldable fabric sofa includes a sofa body, two cushions, a support board, and a back panel, and also includes:

[0009] Deployment mechanism: The deployment mechanism is set on the top outer wall of the support plate. The top outer wall of the support plate has several equally spaced sliding grooves. One outer wall of the baffle is provided with a support frame and several equally spaced support rods. The bottom outer wall of the support frame is provided with four casters. One outer wall of the support frame is provided with an assembly plate. Limiting grooves are opened on both outer walls of the assembly plate. Limiting components are provided on the inner wall of the opposite side of the sofa body.

[0010] Fixing mechanism: The fixing mechanism is installed on one outer wall of the support frame.

[0011] In this case, the connection structure between the sofa body and its unfolded part adopts a detachable design, which allows the sofa to be transformed from a regular sitting position to an unfolded position to form a larger resting surface, and it can also be completely disassembled to facilitate thorough cleaning of its bottom area, increasing the flexibility of use. The use of limiting components ensures the structural stability of the sofa when changing its shape and prevents the unfolded part from detaching from the sofa body. In practical applications, the casters are equipped with a locking structure to further ensure its stability during use.

[0012] In a preferred embodiment, the limiting component includes a limiting rod. Mounting grooves are formed on opposite inner walls of the sofa body. An assembly cavity is formed on the bottom inner wall of each mounting groove. A connecting groove is formed on one inner wall of each assembly cavity. A storage cavity is formed on the bottom inner wall of each connecting groove. A connecting rod is slidably mounted on the inner wall of the connecting groove. Limiting plates are provided at both ends of the connecting rod. The limiting rod is mounted on one outer wall of one of the limiting plates. The outer wall of one of the limiting plates, away from the limiting rod, is connected by a spring to one inner wall of the assembly cavity.

[0013] Specifically, the limiting component is a key structure that ensures the stability of the sofa after it is unfolded. It provides a reliable limiting mechanism for the overall structure, preventing the sofa from accidentally sliding or folding when unfolded, thus enhancing safety. When the sofa is unfolded, the limiting groove on the assembly plate slides to the opening of the mounting groove, and the limiting rod automatically pops out under the action of the spring, locking the position with the limiting groove. When retracted, the limiting rod is squeezed and retracts into the assembly cavity, completing the unlocking. This design is easy to operate, reliable in limiting, and makes it easier for users to clean the bottom area of ​​the unfolded part.

[0014] As described above, an unfoldable fabric sofa includes a sofa body, two cushions, a support board, and a baffle. It further includes: an unfolding mechanism: the unfolding mechanism is disposed on the top outer wall of the support board, the top outer wall of the support board has several equally spaced sliding grooves, one outer wall of the baffle has a support frame and several equally spaced support rods, the bottom outer wall of the support frame has four casters, one outer wall of the support frame has an assembly plate, both outer walls of the assembly plate have limit grooves, and the opposite inner wall of the sofa body has limit components; and a fixing mechanism: the fixing mechanism is disposed on one outer wall of the support frame. The unfoldable fabric sofa provided by this utility model has the technical effects of reducing cleaning difficulty and improving the convenience and flexibility of sofa use.

[0022] 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, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] The unfoldable fabric sofa disclosed in this utility model is mainly used in situations where fabric sofas often adopt a connected structure. Due to the narrow space and complex structure at the bottom of the unfolded area, dirt and grime easily accumulate, making it difficult for commonly used cleaning tools such as brooms and vacuum cleaners to reach in, thus making cleaning extremely difficult.

[0024] Reference Figure 1 and Figure 2An unfoldable fabric sofa includes a sofa body 1, two cushions 2, a support plate 5, and a baffle 3. It also includes: an unfolding mechanism: the unfolding mechanism is located on the top outer wall of the support plate 5, which has several equally spaced grooves 6. A support frame 4 and several equally spaced support rods 7 are located on one outer wall of the baffle 3. Four casters 11 are located on the bottom outer wall of the support frame 4. An assembly plate 8 is located on one outer wall of the support frame 4, and limit grooves 9 are located on both outer walls of the assembly plate 8. Limiting components are located on the opposite inner wall of the sofa body 1. A fixing mechanism: the fixing mechanism is located on one outer wall of the support frame 4.

[0025] The support plate 5 is set on the inner wall of the opposite side of the sofa body 1, the cushion 2 is set on the top outer wall of the support plate 5, and a storage groove 15 is opened on one outer wall of the sofa body 1. One end of the support rod 7 is in contact with the inner wall of the storage groove 15.

[0026] The length of the support rod 7 is greater than the length of the slide groove 6. This design ensures that, in the unfolded state, one end of the support rod 7 and the slide groove 6 can form a support structure, thus ensuring the structural stability of the connection part.

[0027] In the specific implementation process, the connection structure between the sofa body 1 and its unfolded part adopts a detachable design, which allows the sofa to be transformed from a regular sitting position to an unfolded position to form a larger resting surface, and it can also be completely disassembled to facilitate thorough cleaning of its bottom area, increasing the flexibility of use. The limiting component ensures the structural stability of the sofa when changing its shape and prevents the unfolded part from detaching from the sofa body 1. In practical applications, the casters 11 are equipped with a locking structure, which can further ensure its stability of use.

[0028] Reference Figure 1 and Figure 4 In a preferred embodiment, the limiting component includes a limiting rod 20. Mounting grooves are provided on the inner walls of opposite sides of the sofa body 1. An assembly cavity 17 is provided on the bottom inner wall of the mounting groove. A connecting groove is provided on one side inner wall of the assembly cavity 17. A storage cavity 16 is provided on the bottom inner wall of the connecting groove. A connecting rod 18 is slidably mounted on the inner wall of the connecting groove. Limiting plates 19 are provided at both ends of the connecting rod 18. The limiting rod 20 is mounted on one side outer wall of one of the limiting plates 19. The outer wall of one of the limiting plates 19, away from the limiting rod 20, is connected to one side inner wall of the assembly cavity 17 by a spring. The limiting rod 20 works in conjunction with the limiting groove 9.

[0029] Specifically, the limiting component is a key structure that ensures the stability of the sofa after it is unfolded. It provides a reliable limiting mechanism for the overall structure, preventing the sofa from accidentally sliding or folding when unfolded, thus enhancing safety. When the sofa is unfolded, the limiting groove 9 on the assembly plate 8 slides to the mounting groove opening, and the limiting rod 20 automatically pops out under the action of the spring, locking its position in conjunction with the limiting groove 9. When retracted, the limiting rod 20 is squeezed and retracts into the assembly cavity 17, completing the unlocking. This design is easy to operate, reliable in limiting, and makes it easier for users to clean the bottom area of ​​the unfolded part.

[0030] Reference Figure 1 and Figure 3 In a preferred embodiment, the fixing mechanism includes two insert rods 10, both of which are disposed on one side of the outer wall of the support frame 4. The outer circumferential wall of the insert rod 10 is provided with a groove. Two slots 12 are provided on one side of the outer wall of the sofa body 1. Two fixing grooves 13 are provided on the inner circumferential wall of the slots 12. Steel balls 14 are provided on the bottom inner wall of the fixing grooves 13 by means of springs.

[0031] In particular, the fixing mechanism provides a second fixing mechanism for the sofa body 1 and the unfolded part, providing stability for the sofa in the unfolded state. The cooperative design of the insertion rod 10 and the slot 12 makes the connection between the support frame 4 and the sofa body 1 more secure. When the sofa does not need to be unfolded, the insertion rod 10 is inserted into the slot 12, and the steel ball 14 is locked into the groove under the action of the spring, producing a clear positioning feeling and sound prompt. This fixing mechanism prevents the sofa from shifting when it does not need to be unfolded, thus affecting the user's experience.

[0032] Reference Figure 1 and Figure 3 In a preferred embodiment, the length of the insert 10 is the same as the depth of the slot 12, and the diameter of the steel ball 14 is the same as the width of the groove.

[0033] It should be noted that when the insertion rod 10 is fully inserted, its end just contacts the bottom of the slot 12, and the groove position is exactly aligned with the steel ball 14 in the fixing groove 13. This size design ensures that the steel ball 14 can be accurately inserted into the groove, and avoids the insertion rod 10 being too long and causing impact on the bottom of the slot 12, thereby improving the user experience and reliability of the product.

[0034] Working principle: When in use, the user pulls the baffle 3, the insertion rod 10 is pulled out of the slot 12, and then the universal wheel 11 is used to move and drive the support rod 7 to unfold to form a support surface. The limiting groove 9 on the assembly plate 8 slides to the installation groove, and the limiting rod 20 pops out under the action of the spring and is locked into the limiting groove 9, thus achieving fixation. When it is not necessary to unfold, the baffle 3 is pushed to be parallel to one side of the outer wall of the support plate 5. The limiting rod 20 is squeezed and retracts into the assembly cavity 17, releasing the lock. The insertion rod 10 on the support frame 4 is inserted into the slot 12 of the sofa body 1. The steel ball 14 is locked into the groove of the insertion rod 10 under the action of the spring, thus achieving a stable connection. When cleaning is required, the baffle 3 can be pulled until the limiting component and the fixing mechanism are both unlocked. The unfolded part can be moved to another position using the universal wheel 11, and its bottom can be cleaned.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
