Description

Technical Field

[0001] This utility model relates to the field of home furnishings, specifically to a sofa. Background Technology

[0002] Existing roll-up sofas consist of multiple support pads connected in sequence. The sofa shape is achieved by folding and swinging adjacent support pads together, and the thickness of the support pads is reduced to facilitate rolling. However, this type of sofa has the following drawbacks: the support pads are all supported by foam blocks, which provides a limited support experience and cannot provide comfortable support for the user. Furthermore, the support pads need to be folded and assembled, and the lack of reliable connection between the stacked support pads can easily lead to force shifting, affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rollable sofa with springs. A spring is installed inside the sofa body in the same direction as the flattening of the body. The spring can be simultaneously flattened and rolled up when the sofa is switched to the storage state. This makes it convenient to store, eliminates the need for assembly, and allows for direct use after unfolding. The spring also provides comfortable support, enhancing the user experience.

[0004] This utility model is achieved through the following method: a rollable sofa with springs, comprising a main body, the main body including a seat, armrests disposed on the sides of the seat, and a backrest disposed at the rear of the seat. The seat includes an outer shell with an internal cavity and vertically arranged springs in a matrix within the cavity. The main body can switch between a fully unfolded, usable state and a vertically flattened and rolled-up storage state. The springs are housed within the main body, with their axes aligned with the flattening direction of the main body. The springs are simultaneously flattened and rolled up when the sofa is switched to the storage state, facilitating both storage and use without requiring folding and assembly after switching to the usable state. This also protects the springs, ensuring they only extend and retract along their axes without irreversible deformation, while providing comfortable support and enhancing the user experience.

[0005] Preferably, the base includes a base and a cover plate. A receiving groove is formed in the center of the top surface of the base, and the cover plate covers the opening of the receiving groove and encloses it to form the receiving cavity. The outer shell has a split structure, including the base and the cover plate, which facilitates spring installation, improves disassembly and maintenance efficiency, protects and limits the spring, effectively reduces the foreign object sensation caused by the spring to the user, and improves support comfort. The center of the cover plate overlaps the top of the spring and is fixed to the top surface of the base by adhesion to its periphery, ensuring that the spring is tightly wrapped within the receiving cavity.

[0006] Preferably, the slot has a recessed platform around its perimeter, and the cover plate is embedded in the slot and overlaps the platform around its perimeter, so that the top surface of the cover plate is flush with the top surface of the outer shell. The depth of the recessed platform matches the thickness of the cover plate, and the bottom wall of the recessed platform can fit against the perimeter of the bottom surface of the cover plate, providing support for the cover plate and ensuring that the top surface of the cover plate is flush with the top surface of the base. The perimeter contour of the cover plate matches the perimeter contour of the recessed platform, and the sidewalls of the cover plate and the sidewalls of the recessed platform are set close together, effectively eliminating gaps between them, improving aesthetics, and eliminating the feeling of foreign objects.

[0007] Preferably, the diameter of the spring is A, where 5cm≤A≤8cm, to reduce the curling radius when the body is switched to the storage state. This prevents the spring from undergoing irreversible deformation when it is flattened and curled with the body, ensuring that the spring can curl with the body in its flattened shape. It also effectively limits the number of springs, reduces costs, improves the vertical support reliability of the spring, and prevents the spring from radially shifting and tilting.

[0008] Preferably, the spring is a pocket spring, comprising a spring body and a cloth bag enclosing the spring body. Adjacent springs are fixed together by sewing the cloth bag, ensuring that the connected pocket springs are fixed together and improving linkage, while also using the cloth bag to guide and limit the extension and contraction of each spring body. The pocket springs located in the receiving cavity are all fixed together as a whole, facilitating disassembly and removal, and ensuring that each pocket spring can match and link together when under force, improving support comfort.

[0009] Preferably, the backrest, armrests, and outer shell are an integral structure with fixed relative positions, guiding them to accurately reset when the main body switches to the usage state. The integral molding of the backrest, armrests, and outer shell facilitates processing and ensures good structural strength among them, allowing the main body to automatically deform and reset through its own elasticity, thus improving ease of use.

[0010] Preferably, the vertical projections of the backrest and the spring are staggered, the vertical projections of the armrest and the spring are staggered, and the receiving groove, backrest and armrest are staggered, so that the opening of the receiving groove is exposed, making it convenient to put in and take out the spring.

[0011] Preferably, the backrest, armrests, and outer shell are made of sponge material, which ensures that the backrest, armrests, and outer shell can be vertically compressed when subjected to force, making them easy to roll up, and can also achieve deformation recovery through their own elasticity, while effectively reducing costs.

[0012] Preferably, the cover is made of sponge material, which not only effectively reduces costs, but also eliminates the foreign object sensation formed at the top of the spring by its own deformation, thus improving the comfort of use.

[0013] Preferably, the main body includes an independently mounted cushion, which can be independently flattened and rolled up. The cushion rests against the backrest, providing support for the user.

[0014] Preferably, the sofa includes a detachable cover that completely wraps around the main body from top to bottom. This complete coverage not only protects the main body but also facilitates disassembly and cleaning. Furthermore, it allows for the replacement of covers with different decorative styles and materials to meet the diverse needs of users.

[0015] The beneficial effects of this utility model are as follows: A spring is set inside the body, and the spring axis is consistent with the flattening direction of the body. The spring can be flattened and rolled up simultaneously when the sofa is switched to the storage state, which is convenient for storage and use, eliminating the need to fold and assemble after switching to the use state. It also protects the spring, ensuring that the spring only stretches and contracts along its axis and does not undergo irreversible deformation. In addition, the spring provides comfortable support and improves the user experience. Attached Figure Description

[0021] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 and 2 The illustrated rollable sofa with springs comprises a main body including a seat 1, armrests 2 on the sides of the seat 1, and a backrest 3 at the rear of the seat 1. The seat 1 features an outer shell with an internal cavity and vertically arranged springs 6 within the cavity in a matrix configuration. The main body can switch between a fully unfolded, usable state and a vertically flattened and rolled-up storage state. The springs 6 are housed within the main body, with their axes aligned with the flattening direction of the main body. When the sofa is switched to the storage state, the springs 6 are simultaneously flattened and rolled up, facilitating both storage and use without requiring folding and assembly after switching to the usable state. This also protects the springs 6, ensuring they only extend and retract along their axes without irreversible deformation, while providing comfortable support and enhancing the user experience.

[0023] In actual operation, the seat 1 includes a base 4 and a cover plate 5. A receiving groove is formed in the center of the top surface of the base 4, and the cover plate 5 covers the opening of the receiving groove and encloses it to form the receiving cavity. The vertical projections of the backrest 3 and the spring 6 are staggered, and the vertical projections of the armrest 2 and the spring 6 are also staggered. Specifically, the backrest 3 is located at the rear edge of the opening of the receiving groove, and the armrest 2 is located at the side edge of the opening of the receiving groove. By avoiding the opening of the receiving groove, the spring 6 can be easily installed and removed.

[0024] During production, firstly, the springs 6, which are connected in a matrix, are inserted into the receiving groove through the slot. Then, the cover plate 5 is embedded into the recessed platform 8 and is flush with the top surface of the base 4. Finally, the outer cover is placed on the main body.

[0025] After production is completed, the main body is completely wrapped by the outer cover. The area where the spring 6 is set on the base 4 forms a sitting support area. The armrest 2 and the backrest 3 are both located at the edge of the sitting support area, providing support for the user and improving the comfort of use.

[0026] In practice, the sofa is usually in its unfolded state for convenient use. When it needs to be switched to the folded state, firstly, the main body is vertically flattened. The backrest 3, armrests 2, base 4, cover plate 5, and springs 6 inside the main body are all vertically compressed into a sheet shape. Then, the main body is rolled up from one side of the sheet shape to form a cylinder, thus switching the main body to the folded state (e.g., ...). Figure 4 (As shown). During the storage process, the main body can be first placed into a storage bag, and then vertically flattened by vacuuming, or it can be flattened by applying vertical squeezing force through an external device. Both should be considered as specific embodiments of this utility model.

[0027] In actual operation, a recessed platform 8 is provided around the groove (e.g., Figure 3 As shown, the cover plate 5 is embedded in the slot and overlaps the recessed platform 8 around its periphery, so that the top surface of the cover plate 5 is flush with the top surface of the outer shell. The side wall of the recessed platform 8 is annular and its outline matches the outline of the side wall of the cover plate 5. The thickness of the cover plate 5 matches the height of the side wall of the recessed platform 8. The height of the spring 6 matches the depth of the receiving groove. When the spring 6 is installed in the receiving groove, the top surface of the spring 6 is flush with the bottom wall of the recessed platform 8, and the side wall of the spring 6 is close to the side wall of the receiving groove, effectively reducing the gap between the two. The cover plate 5 is embedded in the slot and overlaps the recessed platform 8 around its bottom periphery. The middle part of the bottom surface of the cover plate 5 overlaps the top surface of the spring 6, and the side wall of the cover plate 5 is close to the side wall of the recessed platform 8, effectively reducing the gap between the two. This ensures that the base 4, the spring 6, and the cover plate 5 are matched and fixed together. The mutual contact and contact reduce the space for movement, thereby preventing relative displacement between the base 4, the spring 6, and the cover plate 5.

[0028] In practical operation, the diameter of the spring 6 is A, where 5cm ≤ A ≤ 8cm, to reduce the curling radius when the body switches to the storage state. This prevents irreversible deformation of the spring 6 when it is flattened and curled along with the body, ensuring that the spring 6 can curl with the body in its flattened shape. It also effectively limits the number of springs 6, reduces costs, improves the vertical support reliability of the spring 6, and prevents radial offset and tilting of the spring 6. The parameter A can be 5cm, 6cm, 7cm, 8cm, etc., and all should be considered as specific embodiments of this utility model.

[0029] In actual operation, the spring 6 is a bag spring, including a spring body and a cloth bag that wraps the spring body. Adjacent springs 6 are fixed together by sewing the cloth bag. This not only makes it convenient to assemble and process the corresponding springs 6 according to the size of the receiving slot, thus improving production efficiency, but also allows the cloth bag to be used to fix adjacent spring bodies by sewing, ensuring that the connected spring bodies can be fixed together by the cloth bag and matched and linked, ensuring that the spring 6 can diffuse the vertical force it receives to the surrounding springs 6, thus improving the comfort of vertical support.

[0030] In actual operation, the backrest 3, armrest 2 and shell are an integral structure with fixed relative positions to guide the backrest 3, armrest 2 and shell to accurately reset when the main body is switched to the use state. The backrest 3, armrest 2 and shell are made of sponge material, which is convenient for integrated cutting and processing, can effectively reduce costs, and has good deformation and deformation recovery, ensuring that the main body can freely and frequently switch between the storage state and the use state, thus extending the service life of the main body.

[0031] In practice, the cover plate 5 is made of sponge material, which is convenient to process and use, and also effectively reduces costs. In addition, the cover plate 5 can also be made of other materials, such as rubber, silicone, or fiber, to improve seating comfort; all of these should be considered specific embodiments of this utility model.

[0032] In actual operation, the main body includes an independently set backrest 7, which can be independently flattened and rolled up. The backrest 7 is independently set and can be leaned against the backrest 3, effectively improving the comfort of the backrest 3. Users can select and use it as needed, and this should also be regarded as a specific embodiment of this utility model.

[0033] In practice, the sofa includes a detachable cover that completely wraps around the main body from top to bottom. This complete wrapping not only protects the main body but also facilitates disassembly and cleaning. Furthermore, it allows for the replacement of covers with different decorative styles and materials to meet the diverse needs of users.

[0034] In this embodiment, the seat 1 can be one or more. When there are multiple seat 1s, the seat 1 can be assembled to increase the body size, and can also be independently flattened and rolled up for easy storage and transportation. This should also be regarded as a specific embodiment of this utility model.
