Example

[0024] This embodiment is a modular furniture, which is a sofa. It is composed of a first functional component 10 and a second functional component 20. For example, in some specific embodiments, the first functional component 10 is a sofa base, and the second functional component 20 is a sofa backrest or a sofa armrest. The backrest has the same structure as the sofa, but is installed at a different position from the base. The size of the backrest and the sofa can be the same or different, depending on the specific product requirements.

[0025] In this embodiment, the first functional component 10 and the second functional component 20 have a defined spatial relationship, and this spatial relationship enables the formation of a variety of furniture of different types, sizes and structures. And this spatial relationship can be changed by the detachable connection between the first functional component 10 and the second functional component 20. Each functional component can be one or more, and can be detachably connected to each other to form sofas of various structures. For example, in some specific embodiments, a base is configured with a backrest to form a single sofa without armrests, see Figure 1 In another specific embodiment, a base is equipped with a backrest and two armrests to form a single sofa with armrests, see Figure 2 It can also be composed of two bases with two backrests and two armrests, forming a double sofa with armrests, see Figure 3 .

[0026] The first functional assembly 10 is configured to provide a comfortable sitting surface for the user. In this embodiment, the first functional assembly 10 includes a base frame 101 and a base cushion 102, and the base cushion 102 is mounted on the base frame 101. When the user sits on the first functional assembly 10, the base frame 101 supports the user's weight. The base cushion 102 is used to provide a useful and comfortable sitting area for the user. The base cushion 102 can be easily installed on or removed from the base frame 101.

[0027] The first functional component 10 is a rectangular parallelepiped with four adjacent side surfaces and an upper surface. According to different combinations, one, two or three adjacent side surfaces are adjacent to the second functional component 20 . The upper surface is adjacent to the base cushion 102 .

[0028] In this embodiment, the second functional component 20 includes a backrest frame 201 and a backrest cushion 202, and the backrest cushion 202 is installed on the backrest frame 201. The backrest frame 201 of the second functional component 20 is a rectangular parallelepiped as a whole, and has four adjacent side surfaces around it, and any of the adjacent side surfaces is adjacent to the first functional component 10 to form different furniture. The backrest cushion 202 of the second functional component 20 as a backrest is generally in a wedge shape with a narrow upper part and a wide lower part, so that the user can lean on it more comfortably.

[0029] In this embodiment, a headrest 203 is also provided on the second functional component 20 of the modular furniture.

[0030] In this embodiment, a flexible frame cover is also provided on the outer surface of the base frame 101 and the backrest frame 201, and the frame cover can be configured with different colors and different materials, and the user can replace it according to actual use requirements.

[0031] In this embodiment, the first functional component 10 and the second functional component 20 of the modular furniture are detachably connected via a connecting unit 30. The connecting unit 30 may be disposed at a position where the upper surface of the first functional component 10 and the upper surface of another adjacent first functional component 10 (see 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 a first functional component 10 and the lower surface of another adjacent first functional component 10 (see Figure 5 ), or all three positions may be connected by the connecting unit 30. Figure 6The connection unit 30 includes two fixing restricting members 31 and a connecting member 32. During installation, one fixing restricting member 31 is installed on the first functional component 10, and the other fixing restricting member 31 is installed on another first functional component 10 or second functional component 20 adjacent thereto. The fixing restricting member 31 and the connecting member 32 may be made of plastic or metal. Before being connected by the connecting member 32, the two fixing restricting members 31 are separated from each other, and are connected by the connecting member 32, thereby realizing the connection of two adjacent functional components.

[0032] The structure of the fixed limiting member 31 is shown in Figure 7 The two fixed limiting members 31 have the same structure, so they can be used interchangeably, simplifying the steps of production, installation, and parts configuration. The fixed limiting member 31 is in the shape of an elongated strip as a whole, and includes a limiting portion 311 for fixing and limiting the connecting member 32 and a fixing portion 312 for fixing the fixed limiting member 31 to the first functional component 10 or the second functional component 20. The fixing portion 321 is located at both ends of the limiting portion 311. Two limiting holes 311a are provided on the limiting portion 311, and the connecting member 32 is fixed and limited by a limiting member 313 that cooperates with the limiting holes 311a. A locking hole 311b is also provided between the two limiting holes 311a, and a locking matching hole 321b corresponding to the locking hole 311b is provided on the connecting member 32, and the connecting member 32 is locked with the fixed limiting member 31 by the locking member, so as to further enhance the stability and firmness of the connection. The fixing portion 312 is provided with a screw hole 312 a , and the fixing restriction member 31 is fixed to the corresponding functional component by means of a locking screw.

[0033] The limiting members 313 on the limiting portion 311 may both be detachable, or one may be fixed and the other detachable. This can also achieve its function and simplify the installation process for the user.

[0034] The structure of the connecting member 32 is shown in FIG8 . The connecting member 32 is in the shape of a sheet and includes a main body portion 321 in the middle 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 the connecting member 32 is greater than the width of the connecting portion 322. At the position where the main body portion 321 and the connecting portion 322 are connected, limiting angles 321a located on both sides of the main body portion 321 are formed. The limiting member 313 cooperates with the limiting angles 321a to fix and limit the connecting member 32. The connecting portion 322 of the connecting member 32 is bent downward to the side away from the main body portion 321 to form a bent portion 323. In the installed state, the bent portion 323 abuts against the outer side of the fixed limiting member 31 to further stabilize the connection position.

[0035] In another specific embodiment, the number of connecting members 30 between each first functional component 10 and the second functional component 20 may be one or more, for example, two or more, depending on the required connection strength and the length of the first functional component 10 and the second functional component 20 .

[0036] The connection unit in this embodiment is symmetrical as a whole, which is reflected in that the structure of the fixed limiting member 31 can be completely the same, and there is no need to selectively install corresponding functional components. Further, the connecting member 32 itself is symmetrical, and its two connecting parts 322 are symmetrical about the main body part 321. During installation, the use direction is not restricted and can be turned 180 degrees, which is convenient for installation.

[0037] The two fixing limiters 31 are pre-installed on the corresponding functional components in advance. When the user performs subsequent installation, he only needs to use the connecting member 32 to cooperate with the fixing limiters 31 for installation.

[0038] The first functional component 10 is connected to the second functional component 20 or the lower part of the first functional component 10 .

[0039] During installation, one of the functional components is turned over with the bottom facing one side, the connector 32 is installed on it, and the other functional component 10 is hung from top to bottom into the connector 32. Therefore, the bent portion 323 of the connector 32 also plays a guiding role during the installation process, guiding the fixed limiting member 31 to enter under the connector 32 until the limiting member abuts against the limiting angle of the connector.

[0040] The first functional components 10 are connected to the upper surface of the first functional components 10 .

[0041] During installation, align and bring the front end of the first functional component 10 roughly together, insert the connecting piece 32, make the limiting piece press against the limiting angle, restrict the two fixed limiting pieces 31 in the connecting piece 32, and lock the locking screws with the locking holes to complete the installation.

[0042] Due to the connection between the second functional component 20 and the upper surface of the first functional component 10, the second functional component 20 has no plane at the connection position, and the fixing limiter 31 cannot be installed. In order to also be applicable to the fixing limiter 31 on the first functional component 10, the connection structure is also designed specifically in this embodiment, see Fig. 9 The connecting structure 40 includes an inverted L-shaped main body, and the end of the transverse region has a limiting angle formed with the same as the connecting member, and cooperates with the limiting member. The vertical region is provided with a screw hole, which is connected to the backrest frame 201 of the second functional component 10.
