Description

Technical Field

[0001] The utility model belongs to the technical field of furniture, and in particular relates to a connector for modular furniture and the modular furniture. Background Art

[0002] Traditional furniture, such as sofas, is often constructed as a single piece. While the frame and seat cushions are separable, the frame remains integral. This makes storage and transportation difficult, and inconvenient for daily cleaning and maintenance. Furthermore, this type of furniture, with its specific shape and structure, is fixed upon purchase and cannot be altered at will.

[0003] Consequently, 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 varying styles and functions. This type of furniture offers flexibility and adaptability, meeting the needs of various spaces and scenarios, while also facilitating storage, transportation, and daily maintenance.

[0004] For modular furniture, the connections between modules are crucial. These connections must be strong and stable, yet easy to operate and convenient for users to install and remove. Currently, there are numerous publicly available technologies for connecting modules in modular furniture.

[0005] For example, CN216723894U discloses a furniture connector and sofa comprising a connecting strip, a connecting screw, and a clamping plate. The connecting strip has a through-hole through which the connecting screw passes, and an abutment is fixed to the connecting screw. The clamping plate has a clamping slot with one end open, and the connecting strip slides into the slot. When the abutment moves to a position against the connecting strip, the force applied by the connecting strip to the clamping plate includes a longitudinal component, which is in the same direction as the force applied by the abutment to the connecting strip. However, this connector requires lifting the sofa base, backrest, or armrests during installation, making it inconvenient to operate. Furthermore, the connector requires the use of screws to restrict the horizontal front and rear movement.

[0006] Another example is a modular furniture assembly disclosed in CN101217900A, which includes a base and a cross member that is manually connected to the base in a detachable manner via a connector. The base and the cross member have a defined spatial relationship, which enables furniture assemblies of different types, structures, and sizes to be formed by the base and the cross member. Moreover, the base is constructed so that the cross member can be connected to the base at a first position to form a first furniture assembly, and can be connected to the base at a second position to form a second furniture assembly. The connector therein is a U-shaped connector that is inserted into the corresponding holes of the base and the cross member. This type of connector has poor restrictive properties on the base and the cross member. For example, it cannot restrict the horizontal movement of the two, and it is also easy for the connector to detach from the hole under the action of unexpected external force. Utility Model Content

DETAILED DESCRIPTION

[0057] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific implementation cases.

[0058] It should be noted that the following implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention is described in detail with reference to the following implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in each implementation case, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of each implementation case of the present invention. Example

[0059] This embodiment provides a connector suitable for connecting and assembling furniture units 10 of modular furniture. Figure 1 , mainly includes three parts, a first fixing member 21, a second fixing member 22 and a connecting member 23. The first fixing member 21 is fixedly installed on the substantially straight portion 100 of the lower surface of a furniture unit 10 of the modular furniture, and the second fixing member 22 is fixedly installed on the substantially straight portion 100 of the lower surface of another furniture unit 10 to be connected to the previous furniture unit 10, and then connected through the connecting member 23, see Figure 2 、 Figure 3 One end of the connecting member 23 is inserted into the first fixing member 21 and is restricted from being pulled out by the first fixing member 21 , and the other end of the connecting member 23 is inserted into the second fixing member 22 .

[0060] In this embodiment, the first fixing member 21 and the second fixing member 22 have the same structure, see Figure 4 The furniture unit 10 comprises a fixed body 21a, which is an elongated strip of a certain thickness and can be made of metal. The upper surface of the fixed body 21a includes a front abutment plate 21b and a rear abutment plate 21c, which are perpendicular to the fixed body 21a and are substantially parallel to the rear abutment plate 21c. The front abutment plate 21b and the rear abutment plate 21c can be formed by bending the ends of the fixed body 21a upward, or can be connected to the fixed body 21a by welding or other means, or can be obtained by an integral molding process. The rear abutment plate 21c has a hole 22c-1 for one end of the connecting member 23 to pass through, and the fixed body 21a has an insertion hole 22a-1 for the other end of the connecting member 23 to pass through. The insertion hole 22a-1 corresponds to the connecting hole 10a on the furniture unit 10.

[0061] In order to better restrict the connection, the horizontal width d of the hole 22c-1 on the rear support plate 21c is basically equal to the width d' of the part of the connecting member 23 passing through the hole 22c-1, that is, the width d of the hole 22c-1 allows the connecting member 23 to pass through smoothly, but can also limit the left and right movement of the connecting member 23 to the maximum extent.

[0062] Under the above structure of the first fixing member 21 and the second fixing member 22 , the rear support plate 21 c on the second fixing member 22 forms a supporting portion to support the connecting member 23 , thereby improving the stability of the connection.

[0063] The first fixing member 21 and the second fixing member 22 have the same structural configuration, which is conducive to more mass production and unified configuration on the furniture unit 10, and makes it easier to implement random combination of furniture units 10.

[0064] However, in another specific embodiment, the structures of the first fixing member 21 and the second fixing member 22 may also be partially different. Figure 5 The first fixing member 21 lacks the insertion hole 22a-1, the second fixing member 22 lacks the front support plate 21b, and the rear support plate 21c lacks the hole 22c-1. These differences can be selectively incorporated into either or both the first fixing member 21 or the second fixing member 22. For example, the second fixing member 22 can differ from the first fixing member 21 solely by lacking the front support plate 21b, or both by lacking the front support plate 21b and lacking the hole 22c-1 in the rear support plate 21c.

[0065] Even in another specific embodiment, the second fixing member 22 is configured to have a structure completely different from that of the first fixing member 21, see Figure 6 The second fixing member 22 is a block having a support portion 22a for supporting the connecting member 23 and an insertion hole 22b corresponding to the connection hole 10a on the furniture unit 10.

[0066] In another embodiment, see Figure 7 An end abutment plate 21d is provided outside the front abutment plate 21b of the first fixing member 21. In the coupled state, the end of the connecting member 23 abuts against this end abutment plate 21d. The end abutment plate 21d is formed by bending the front abutment plate 21b outward. The width of the bent portion is smaller than the width of the end of the connecting member 23.

[0067] The fixing bodies 21a of the first and second fixing members 21, 22 are provided with fixing holes 21-1, which can be pre-fixed to corresponding positions of the corresponding furniture unit 10 with screws, or configured as independent units, which the user can secure to the corresponding positions during installation. Pre-installation simplifies the user's installation process, but it cannot predict the user's assembly method for the furniture unit 10, resulting in unnecessary installation. Independent configuration, while increasing the number of installation steps, allows the user to choose whether to install the first and second fixing members 21, 22 on the furniture unit 10 based on their desired assembly method, providing greater flexibility and reducing unnecessary parts waste.

[0068] In this embodiment, the connecting member 23 is in the shape of a long strip with a certain thickness, and can be made of metal. Figure 8 The connecting member 23 includes a reference portion 23a inserted into the first fixing member 21, a vertical abutting portion 23b extending upward from the reference portion 23a, a transition portion 23c extending horizontally from the abutting portion 23b, and an insertion portion 23d extending downward from the transition portion 23c and capable of being inserted into the connection hole 10a on the furniture unit 10. The vertical abutting portion 23b abuts the outer surface of the rear abutment plate 21c. The reference portion 23a is provided with a downwardly bent hook portion 23e at one end away from the abutting portion 23b, and the hook portion 23e abuts the outer surface of the front abutment plate 21b. This structure, through the interaction between the hook portion and the front abutment plate 21b, and the interaction between the vertical abutting portion 23b and the rear abutment plate 21c, allows one end of the connecting member 23 to be restrained to the first fixing member 21. The other end of the connecting member 23 is then inserted into the corresponding insertion hole 22b and the connecting hole 10a of the furniture unit 10. The supporting portion of the second fixing member 22 and the rear support plate 21c of the first fixing member 21 further limit the movement of the connecting member 23, thereby providing a more stable connection for the two furniture units 10.

[0069] The various parts of the connecting member 23 can be formed into a whole by integral molding, or can be connected together by welding or other methods.

[0070] Example 2

[0071] This embodiment provides modular furniture, specifically a sofa. The modular furniture is composed of a plurality of furniture units 10. For example, in some embodiments, the furniture unit 10 may be a sofa base, a sofa backrest unit, or a sofa armrest unit. The backrest unit and the sofa unit have the same structure, differing only in their mounting position relative to the sofa base unit. The backrest unit and the sofa unit may have the same or different dimensions, depending on the specific product requirements.

[0072] In this embodiment, the various furniture units 10 have defined spatial relationships with each other, which enables the formation of furniture of various types, sizes, and configurations. Furthermore, this spatial relationship can be changed by detachably connecting the furniture units 10. Each type of furniture unit 10 can be one or more, detachably connected to each other to form sofas of various configurations. For example, in some embodiments, a base unit is configured with a backrest unit to form a single-person sofa without armrests, see Figure 9 In another embodiment, two base units are configured with two backrest units and two armrest units to form a double sofa with armrests, see Figure 10 .

[0073] In this embodiment, the two interconnected furniture units 10 are both sofa bases, each comprising a base frame 101 and a base cushion 102 mounted on the base frame 101. When a user sits on the sofa base, the base frame 101 supports the user's weight. The base cushion 102 provides a useful and comfortable seating area for the user. The base cushion 102 can be easily installed on and removed from the base frame 101.

[0074] The sofa base is generally rectangular, having four adjacent side surfaces, an upper surface, and a lower surface. The lower surface is generally flat or has a substantially flat surface near its edges, facilitating the installation of the first and second fixing members. Depending on the configuration, one, two, or three sides of the lower surface may abut another sofa base, forming a two-seater, three-seater, or single-seater sofa. Furthermore, armrests or a backrest may be provided on the sides of the sofa base.

[0075] In another embodiment, two interconnected furniture units 10 are described, one of which is a sofa base unit and the other a sofa backrest unit. The sofa base unit includes a base frame 101 and a base cushion 102, with the base cushion 102 mounted on the base frame 101. The sofa backrest unit includes a backrest frame and a backrest cushion, with the backrest cushion mounted on the backrest frame. Both the backrest frame and the base frame 101 are rectangular parallelepipeds, each having a substantially flat lower surface, either generally flat or substantially flat near the edges. The lower surface of the base frame 101 is connected to the lower surface of the backrest frame via the connector described in Example 1, forming a sofa with a backrest. The backrest cushion is roughly wedge-shaped, narrow at the top and wide at the bottom, providing a more comfortable reclining position for the user.

[0076] In another embodiment, the sofa backrest of the modular furniture is further provided with a headrest.

[0077] In another embodiment, support feet are provided on the lower surface of the furniture unit of the modular furniture, so that the lower surface of the furniture unit 10 is at a certain distance from the ground, ensuring the normal installation and use of the connector 20.

[0078] In another embodiment, a flexible frame cover is provided on the outer surface of the base frame 101 and the backrest frame. The frame cover can be configured with different colors and different materials, and the user can replace it according to actual use requirements.

[0079] In another embodiment, two interconnected furniture units, one of which is a sofa base and the other is a sofa armrest, are described. The sofa base comprises a base frame 101 and a base cushion 102, with the base cushion 102 mounted on the base frame 101. The sofa armrest comprises an armrest frame and an armrest cushion, with the back cushion armrest covering the armrest frame. Both the base frame 101 and the armrest frame are rectangular parallelepiped units, each having a substantially flat lower surface, either generally flat or substantially flat near the edges. The lower surface of the base frame 101 and the lower surface of the armrest frame are connected via the connector described in Example 1, thereby forming a sofa with armrests.

[0080] In another specific embodiment, the number of connectors 20 between connected furniture units can be one or more, for example, two or more, depending on the required connection strength and the length of the furniture units.
