Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, specifically relating to a connection unit for connecting modular furniture and modular furniture. Background Technology

[0002] Traditional sofas and other furniture are mostly one-piece structures. Although the frame and seat cushions can be separated, the frame is still a single piece. This makes them unsuitable for storage and transportation, and also inconvenient for users to clean and maintain daily. Moreover, with this structure, the shape of the furniture cannot be adjusted after purchase to meet the user's needs.

[0003] Therefore, modular furniture has become the preferred choice for most users in recent years. Modular furniture breaks down furniture into several standard modules, which can then be combined and matched as needed to create furniture products with different styles and functions. This type of furniture is flexible and versatile, meeting the needs of different spaces and scenarios, and is also more conducive to storage, transportation, and daily maintenance.

[0004] Existing technologies, such as CN101208030A, disclose a modular furniture assembly. This assembly includes a base and a transverse member that is manually and detachably connected to the base via a connector. Specifically, the disclosed connector is a U-shaped connector, with each of the base frame and the transverse member frame having a corresponding hole therein, which accommodates a portion of the connector. This connector and connection method may have some problems: 1. It requires the use of holes on the furniture base and transverse member for connection, placing demands on the furniture structure itself and making it unsuitable for furniture without corresponding holes; 2. Using only a U-shaped connector to snap the base and transverse member together results in limited connection strength and makes it prone to movement along the length (x) direction of the base. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a connecting unit for connecting modular furniture and modular furniture in general. This connecting component is easy to install and disassemble, requires no cooperation with the furniture's own structure, has a compact structure, and provides a strong connection.

[0006] The first aspect of this utility model provides a connecting unit, which adopts the following technical solution:

[0007] A connection unit for connecting modular furniture, used to detachably connect a first functional component and a second functional component, the connection unit comprising:

[0008] Two fixing and limiting components are respectively disposed on the first functional component and the second functional component;

[0009] The connector is detachably connected to two fixed limiting members to restrict the relative movement between the first functional component and the second functional component.

[0010] The connecting unit has overall symmetry.

[0011] Preferably, the connector has at least one axis of symmetry.

[0012] Preferably, the connector has two axes of symmetry, and the two axes of symmetry are perpendicular to each other.

[0013] Preferably, the main body portion in the middle of the connector and the connecting portions located at both ends of the main body portion are symmetrical about the main body portion.

[0014] Preferably, the fixing limiting member includes a limiting part for fixing and limiting the connector and a fixing part for fixing the fixing limiting member to the first functional component or the second functional component, and the limiting parts of the two fixing limiting members have the same structure.

[0015] Preferably, the limiting part of the fixing limiting member is provided with two limiting holes, and the connecting member is fixed and limited by the limiting member that cooperates with the limiting holes.

[0016] Preferably, the width of the main body of the connector is greater than the width of the connecting part, and a limiting angle is formed on both sides of the main body at the position where the main body and the connecting part are connected. The limiting member cooperates with the limiting angle to fix and limit the connector.

[0017] Preferably, the limiting part of the fixing limiting member is provided with a locking hole, which is located between two limiting holes. The connecting member is provided with a locking matching hole corresponding to the locking hole, and the connecting member and the fixing limiting member are locked together by the locking member.

[0018] Preferably, one of the limiting members is fixed, while the other limiting member is detachable.

[0019] Preferably, the connecting portion of the connector is bent downwards toward the side away from the main body to form a bent portion.

[0020] In a second aspect, this utility model provides a modular furniture, wherein the first functional component and the second functional component are detachably connected via the aforementioned connecting unit.

[0021] Preferably, the first functional component has at least one substantially flat portion, which is connected to the substantially flat portion of the second functional component via the connecting member.

[0039] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific implementation examples.

[0040] It should be noted that the following implementation examples are only used to illustrate the technical solutions of this utility model, and not to limit it; although this utility model has been described in detail with reference to the following implementation examples, those skilled in the art should understand that they can still modify the technical solutions recorded in each implementation example, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of each implementation example of this utility model. Example

[0041] This embodiment describes a modular furniture, specifically a sofa. It comprises a first functional component 10 and a second functional component 20. For example, in some specific embodiments, the first functional component 10 is the sofa base, and the second functional component 20 is the sofa backrest or armrests. The backrest has the same structure as the sofa but a different installation position relative to the base. The dimensions of the backrest and the sofa can be the same or different, depending on the specific product requirements.

[0042] In this embodiment, the first functional component 10 and the second functional component 20 have a defined spatial relationship, which allows for the formation of various types, sizes, and structures of furniture. This spatial relationship can be altered through a detachable connection between the first functional component 10 and the second functional component 20. Each functional component can be one or more, detachably connected to each other to form sofas with various structures. For example, in some embodiments, a base is configured with a backrest to form an armless single sofa, see [link to relevant documentation]. Figure 1 In another specific embodiment, a base is equipped with a backrest and two armrests, which are combined to form a single sofa with armrests, see [reference needed]. Figure 2 Alternatively, it can consist of two bases with two backrests and two armrests, combined to form a two-seater sofa with armrests. See [link / reference]. Figure 3 .

[0043] The first functional component 10 is configured to provide a comfortable seating surface for the user. In this embodiment, the first functional component 10 includes a base frame 101 and a base cushion 102, the base cushion 102 being mounted on the base frame 101. When the user sits on the first functional component 10, the base frame 101 supports the user's weight. The base cushion 102 provides the user with a useful and comfortable seating area. The base cushion 102 can be easily mounted on or removed from the base frame 101.

[0044] The first functional component 10 is generally rectangular, with four adjacent sides and a top surface. Depending on the configuration, one, two, or three of the adjacent sides are adjacent to the second functional component 20. The top surface is adjacent to the base pad 102.

[0045] In this embodiment, the second functional component 20 includes a backrest frame 201 and a backrest cushion 202, with the backrest cushion 202 mounted on the backrest frame 201. The backrest frame 201 of the second functional component 20 is generally rectangular, with four adjacent sides, and it is adjacent to the first functional component 10 with any one of these adjacent sides to form different pieces of furniture. The backrest cushion 202 of the second functional component 20, serving as the backrest, is generally wedge-shaped, narrower at the top and wider at the bottom, making it more comfortable for the user to lean against.

[0046] In this embodiment, a headrest 203 is also provided on the second functional component 20 of the modular furniture.

[0047] In this embodiment, a flexible frame sleeve is also fitted on the outer surface of the base frame 101 and the backrest frame 201. The frame sleeve can be configured with different colors and materials, and users can replace it according to their actual needs.

[0048] In this embodiment, the first functional component 10 and the second functional component 20 of the modular furniture are detachably connected by a connecting unit 30. The connecting unit 30 can be positioned between the upper surface of the first functional component 10 and the upper surface of another adjacent first functional component 10 (see [link to documentation]). Figure 4 ), or the lower surface of the first functional component 10 and the lower surface of the adjacent second functional component 20 (see Figure 5 ), or the lower surface of the first functional component 10 and the lower surface of another adjacent first functional component 10 (see Figure 5 Any one of the three positions can be connected using the connecting unit 30. Specifically, see [link to details]. Figure 6 The connecting unit 30 includes two fixing members 31 and a connector 32. During installation, one fixing member 31 is mounted on the first functional component 10, and the other fixing member 31 is mounted on another adjacent first functional component 10 or second functional component 20. The fixing members 31 and the connector 32 can be made of plastic or metal. Before connection using the connector 32, the two fixing members 31 are separate from each other; they are connected by the connector 32, thereby achieving the connection between the two adjacent functional components.

[0049] See the structure of the fixing and limiting member 31. Figure 7 The two fixing limiting members 31 have identical structures, allowing for mutual interchangeability and simplifying production, installation, and parts configuration. The fixing limiting member 31 is elongated and includes a limiting part 311 for fixing the connecting member 32 and a fixing part 312 for fixing the fixing limiting member 31 to the first functional component 10 or the second functional component 20. The fixing part 321 is located at both ends of the limiting part 311. The limiting part 311 has two limiting holes 311a, and the connecting member 32 is fixed by a limiting member 313 that mates with the limiting holes 311a. Between the two limiting holes 311a, a locking hole 311b is also provided. The connecting member 32 has a corresponding locking fitting hole 321b, which locks the connecting member 32 to the fixing limiting member 31, further enhancing the stability and firmness of the connection. The fixing part 312 is provided with a screw hole 312a, and the fixing limiting member 31 is fixed to the corresponding functional component by a locking screw.

[0050] The limiting member 313 on the limiting part 311 can be both detachable, or one can be fixed and the other detachable. This can achieve the same function and simplify the user's installation process.

[0051] The structure of connector 32 is shown in Figure 8. It is generally sheet-like, comprising a central main body portion 321 and connecting portions 322 located at both ends of the main body portion 321. The two connecting portions 322 are symmetrical about the main body portion 321. The width of the main body portion 321 of connector 32 is greater than the width of the connecting portions 322. Restriction angles 321a are formed on both sides of the main body portion 321 at the connection point between the main body portion 321 and the connecting portions 322. The restriction member 313 cooperates with the restriction angles 321a to fix and restrict the connector 32. The connecting portions 322 of connector 32 are bent downwards away from the main body portion 321 to form a bent portion 323. In the installed state, this bent portion 323 abuts against the outer side of the fixing restriction member 31, further stabilizing the connection position.

[0052] In another specific embodiment, the connecting member 30 between each first functional component 10 and the second functional component 20 may be one or more, such as two or more, depending on the required connection strength and the length of the first functional component 10 and the second functional component 20.

[0053] In this embodiment, the connecting unit is symmetrical overall. This is reflected in the fact that the structure of the fixing and limiting member 31 can be completely identical, eliminating the need for selective installation of corresponding functional components. Furthermore, the connecting member 32 itself is symmetrical, with its two connecting parts 322 symmetrical about the main body part 321. During installation, its direction of use is unrestricted, and it can be rotated 180° for convenient installation.

[0054] Two fixing components 31 are pre-installed on the corresponding functional components. When the user performs subsequent installation, he / she only needs to use the connector 32 to cooperate with the fixing components 31 for installation.

[0055] The first functional component 10 is connected to the second functional component 20 or the lower part of the first functional component 10.

[0056] During installation, one of the functional components is first flipped to the side with its bottom facing one side, and the connector 32 is installed on it. The other functional component 10 is then hung into the connector 32 from top to bottom. Therefore, the bent portion 323 of the connector 32 also serves as a guide during installation, guiding the fixing restraint 31 into the space below the connector 32 until the restraint abuts against the limiting angle of the connector.

[0057] The first functional component 10 is connected to the upper surface of the first functional component 10.

[0058] During installation, roughly align and bring the front end of the first functional component 10 close to the connector 32, so that the limiting member abuts against the limiting angle, and the two fixed limiting members 31 are restricted within the connector 32. Then, tighten the locking screw and the locking hole to complete the installation.

[0059] Because the connection between the second functional component 20 and the upper surface of the first functional component 10 is limited by the fact that the second functional component 20 has no flat surface at the connection location, the fixing restraint 31 cannot be installed. In order to also accommodate the fixing restraint 31 on the first functional component 10, this embodiment also includes a targeted design for the connection structure, see [link to relevant documentation]. Figure 9 The connecting structure 40 includes an inverted L-shaped main body with a limiting angle formed at the end of its lateral region, which is the same as that of the connector, and engages with the limiting member. A screw hole is provided in the vertical region for connection with the backrest frame 201 of the second functional component 10.
