DETAILED DESCRIPTION

[0038] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figure 1-20 As shown, the present invention has multiple embodiments, and the specific implementation methods are as follows: Example 1: Figure 1-11As shown, this embodiment provides a furniture unit, including a body 1, which is made of EPP material; EPP is a foamed polypropylene material, which is low in weight and high in pressure resistance, and is suitable for use in assembled furniture of various structures; the body 1 includes a first end face 11 and a second end face 12 located at both ends of the body 1, and the inner side of the second end face 12 has a protrusion 121 extending along the length direction of the body 1; a plurality of tooth grooves 122 formed by inward depressions are distributed along the circumferential direction on the outer end face of the protrusion 121, and the tooth grooves 122 are open outwardly along the width direction of the body 1; the first end face 11 is inwardly depressed and formed with a concave hole 111 that can match the protrusion 121, and a plurality of teeth 112 that can match the tooth grooves 122 are distributed along the circumferential direction on the inner wall of the concave hole 111; the protrusion 121 on the furniture unit can match the concave hole 111, and the teeth 112 can match the tooth grooves 122, providing a structural basis for multiple furniture units to be spliced ​​with each other.

[0041] Furthermore, in order to ensure a stable splicing effect, the tooth grooves 122 are evenly arranged on the outer end surface of the protrusion 121 along the circumferential direction, and the teeth 112 are evenly arranged on the inner wall of the recessed hole 111 along the circumferential direction.

[0042] Furthermore, in this embodiment, the shape of the main body 1 can be many, each of which has a different visual effect. For example, the main body 1 can be a cylinder; the cylindrical shape is relatively smooth, which can form a simple and comfortable visual effect in appearance; or the main body 1 can be a prism (not shown); the appearance of the prism has multiple edges, which can form an angular visual effect in appearance.

[0043] Furthermore, in order to reduce the weight of the main body 1, the main body 1 has been designed with multiple weight-reducing features. For example, a through hole 13 concentric with the concave hole 111 is provided at the bottom of the concave hole 111; the through hole 13 can reduce the weight of the main body 1, making it even lighter. In addition, a lightening hole 14 concentric with the concave hole 111 is provided on the outer end surface of the protrusion 121; the lightening hole 14 can further reduce the weight of the main body 1, making it even lighter.

[0044] Furthermore, in order to further reduce weight, the depth of the recessed hole 111 is greater than the extended length of the protrusion 121; after providing a matching length matching the protrusion 121, the recessed hole 111 beyond the protrusion 121 can play a role in reducing weight.

[0045] Further, if Figure 4-8As shown, the present embodiment also proposes another assembled furniture, including a plurality of the furniture units described above, which are assembled by splicing a plurality of furniture units by end-to-end plug-in, and the plurality of furniture units are combined into a cylindrical body. Between two adjacent furniture units, the first end face 11 of one furniture unit is arranged opposite to the second end face 12 of the other furniture unit, and the protrusion 121 of one furniture unit is inserted into the recess 111 of the other furniture unit, and the corresponding tooth portion 112 is matched with the tooth groove 122. After the matching, the lateral and circumferential degrees of freedom between the adjacent furniture units are restricted, and only the longitudinal degree of freedom is not restricted, so that the plurality of furniture units can be directly plugged in and out to form a stable assembled furniture.

[0046] Furthermore, in order to make the assembled furniture have a variety of visual appearance effects, a distance is left between the groove bottom of the tooth groove 122 and the second end face 12, so that a reserved space 15 is formed between two adjacent furniture units after assembly, and a retaining ring 2 can be selectively connected to the reserved space 15; when the retaining ring 2 is not connected, the reserved space 15 can produce a bamboo-like decorative effect in appearance, and when the retaining ring 2 is connected, the cylindrical assembled furniture forms a seamless visual effect in appearance; this structure can form an optional design, so that users can choose the corresponding decorative effect according to their own preferences.

[0047] Further, if Figure 8 As shown, a dovetail groove 113 which gradually narrows from the outside to the inside is formed between every two adjacent teeth 112 in the recessed hole 111, and an insert block 123 which matches the dovetail groove 113 is formed between every two tooth grooves 122 on the second end surface 12. When the teeth 112 of two furniture units cooperate with the tooth grooves 122, the insert block 123 cooperates with the dovetail groove 113 and leaves a gap. The reserved gap can facilitate the plug-in and unplug assembly between the furniture units, and compared with the regular rectangular groove, when the two furniture units tend to move laterally relative to each other, the inwardly narrowed structure of the dovetail groove 113 can limit the insert block 123, so that the structure of the assembled furniture is more stable, while the rectangular grooves are difficult to limit the lateral movement of the furniture units when they are subjected to force due to the same width.

[0048] Furthermore, one end of the tooth portion 112 facing the first end face 11 is flush with the first end face 11; the tooth portion 112 is close to the opening of the first end face 11, which is convenient for matching with the protrusion 121 of another furniture unit. That is to say, the closer the tooth portion 112 is to the first end face 11, the easier it is for the tooth groove 122 on the protrusion 121 to match with the tooth portion 112. If the tooth portion 112 is too close to the second end face 12, the length of the protrusion 121 needs to be designed to be longer to ensure that the tooth portion 112 matches with the tooth groove 122. This design facilitates splicing between multiple furniture units, while reducing the extension length of the protrusion 121, saving material costs.

[0049] Further, if Figure 9-11 As shown, this embodiment also proposes an assembled furniture, including a supporting plate 4 and the furniture unit, and the bottom end of the supporting plate 4 is overlapped on the first end surface 11 of the end of the main body 1, and the supporting plate 4 can be matched with one or more of the furniture units. For example, in this embodiment, the supporting plate 4 is matched with two spaced furniture units to form a structure similar to a long bench with a supporting function.

[0050] Furthermore, considering the stabilizing effect of the support plate 4 placed on the main body 1, a countersunk hole 61a matching the main body 1 is opened at the bottom end of the support plate 4, and the end of the main body 1 with the first end face 11 is inserted into the countersunk hole 61a; the countersunk hole 61a can limit the lateral movement of the support plate 4 relative to the furniture unit, so that the assembled furniture structure is more stable.

[0051] Furthermore, in the assembled furniture, since the outer contour area of ​​the protrusion 121 is smaller than the outer contour area of ​​the main body 1, in order to avoid the protrusion 121 directly contacting the ground and causing the assembled furniture structure to be unstable, the assembled furniture is also provided with a chassis 3 corresponding to the number of furniture units, and the bottom end of the chassis 3 is supported on the ground, and the bottom end of the chassis 3 is connected to a support leg 31 in contact with the ground, and a socket 32 ​​matching the socket 32 ​​of the protrusion 121 is provided at the upper end of the chassis 3, and the protrusion 121 on the furniture unit is inserted into the socket 32, making the assembled furniture more stable.

[0052] Furthermore, in order to enhance the aesthetics of the assembled furniture, a through hole 61 concentric with the recessed hole 111 is provided on the supporting plate 4; through the through hole 61, decorative green plants can be placed into the recessed hole 111, and the branches and leaves of the green plants can be exposed from the through hole 61, thereby enhancing the practicality and aesthetics of the assembled furniture.

[0053] Furthermore, a shielding member 43 for closing the perforation 61 is selectively connected to the support plate 4; when there is no need to place green plants, the perforation 61 can be closed by the shielding member 43 to better meet the needs of users; for example, when the furniture is assembled as a bench, the shielding member 43 can be a round cushion or a long strip cushion 62, and the bottom ends of the cushion and the strip cushion 62 are provided with a boss that is inserted into the perforation 61.

[0054] Furthermore, when it is necessary to place the green plant 7, a cover plate 64 is connected to the perforation 61, and an avoidance hole 65 is opened on the cover plate 64, the position of which corresponds to the perforation 61, and the aperture of the avoidance hole 65 is smaller than the aperture of the perforation 61; when the user places the green plant into the recessed hole 111, the avoidance hole 65 with a smaller aperture can play the role of gathering the branches and leaves, avoiding the branches and leaves from spreading outward in a disorderly manner, and making the supporting plate 4 with the perforation 61 look more coordinated.

[0055] Example 2: Figure 12-13As shown, the difference between this embodiment and the above-mentioned embodiment lies in that this embodiment proposes another assembled furniture, including a connecting member 5 and a plurality of the furniture units, the bottom end of the connecting member 5 is supported on the ground, and the protrusions 121 of the plurality of furniture units are correspondingly connected to the upper end of the connecting member 5 in a detachable manner; specifically, the upper end of the connecting member 5 is provided with mounting holes 51 matching the protrusions 121 on the furniture units, and the number of the mounting holes 51 corresponds to the number of the furniture units; the protrusions 121 of the corresponding furniture units are inserted into the mounting holes 51; so that the assembled furniture containing the furniture units can be indirectly connected through the connecting member 5 to avoid relative lateral movement of the assembled furniture; the bottom end of the connecting member 5 is also connected to a support leg 31 in contact with the ground; for example, tables with furniture units as legs can be connected through the connecting member 5 to avoid lateral movement of the table due to force, resulting in gaps at the joints of the table tops.

[0056] Example 3: Figure 14-18 As shown, the difference between this embodiment and the above-mentioned embodiment lies in that this embodiment proposes another assembled furniture, in which a support plate 6 is arranged between two adjacent furniture units, including the support plate 6 and the two furniture units, the two furniture units are respectively located at the upper and lower ends of the support plate 6, the protrusion 121 of the furniture unit at the upper end is inserted into the concave hole 111 of the furniture unit at the lower end, and the corresponding tooth portion 112 is matched with the tooth groove 122, and a distance is left between the groove bottom of the tooth groove 122 and the second end face 12, so that a reserved space 15 is formed between the upper and lower furniture units after the combination, the support plate 6 is in the reserved space 15, and the upper and lower ends of the support plate 6 are respectively connected to the first end face 11 and the second end face 12; so that in the height direction, a plurality of modular furniture with support plates 6 and furniture units can be assembled into different structures; for example, tables and benches with support plates 6 and furniture units and different heights can be spliced ​​into a whole, so that the modular splicing of furniture is more diverse, and the combination range of modular furniture is broadened.

[0057] Furthermore, in order to avoid relative lateral displacement between the support plate 6 and the furniture unit, a matching hole group is provided on the support plate 6, and the matching hole group includes a countersunk hole 61a that can match the main body 1 and a through hole 61 that can match the protrusion 121, which are opened in sequence from bottom to top. The main body 1 of the furniture unit at the lower end and the protrusion 121 of the furniture unit at the upper end are respectively inserted into the countersunk hole 61a and the through hole 61; the countersunk hole 61a and the through hole 61 can respectively form a limiting effect on the furniture units at the upper and lower ends of the support plate 6 to avoid lateral displacement of the two furniture units.

[0058] Furthermore, in order to facilitate the adjustment of the position of the support plate 6, there is no circumferential restriction on the furniture unit and the support plate 6. Specifically, the protrusion 121 and the main body 1 of the furniture unit are both cylinders, and the countersunk hole 61a and the through hole 61 are both circular holes. After the support plate 6 is combined with the furniture unit, the support plate 6 can rotate relative to the furniture unit in the circumferential direction. This is beneficial for the user to independently change the placement of the support plate 6 according to his own needs during subsequent use, thereby making more effective use of the indoor space.

[0059] In summary, if Figure 19-20 As shown, in the present invention, the furniture units described in multiple embodiments can be freely spliced ​​and assembled to form different furniture systems. A furniture system refers to a combination of multiple furniture with different functions and positions into a new whole. In this furniture system, the assembled furniture can still play their respective roles. For example, the assembled furniture with a table structure and the assembled furniture with a bench structure are connected as one, which not only shortens the distance between the table and the bench and saves space, but also does not affect their respective functions. Therefore, through the splicing and combination of the assembled furniture in the present invention, a furniture system with beautiful appearance, simple structure and practicality can be formed.

[0060] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
