Description

Technical Field

[0001] The present invention relates to a sofa component and a sofa, and in particular to a sofa component for a modular or spliced sofa. Background Art

[0002] With the development of society, people's material living standards have gradually improved. Therefore, as an important part of furniture in daily life, people have put forward higher requirements for sofas.

[0003] Traditional sofas usually use a large amount of wooden materials. In particular, the support frame of a traditional sofa is usually made of multiple wooden boards. Multiple wooden boards often enclose to form a wooden support frame with an internal space, and the main structure of the sofa is installed and fixed in the internal space formed by the wooden support frame. However, when assembling a sofa, a large number of professionals are required to use nail guns to connect and fix the multiple wooden boards to form a complete wooden support frame, and then install it together with the main structure of the sofa. Therefore, the assembly process is relatively cumbersome, time-consuming and laborious, resulting in low production efficiency and increasing the required labor cost. Moreover, since the multiple wooden boards forming the wooden support frame may have different shapes, when producing the wooden boards, it is necessary to complete the processing of each wooden board on the basis of separate drawing programming and typesetting for different wooden boards. This reduces the processing efficiency of the wooden boards and increases the processing cost. In addition, for modular or spliced sofas, it is necessary to fix two wooden support frames on adjacent sofa components together, which usually also has to be completed by professionals, and the installation process is also relatively cumbersome.

[0004] Therefore, it is necessary to improve traditional sofas, especially to improve the wooden support frame of traditional sofas, so as to simplify the structure of the components for supporting the sofa on the ground, thereby simplifying the assembly process of the sofa, improving the aesthetics of the sofa, and improving production efficiency and reducing production costs. Summary of the Invention

[0005] The object of the present invention is to provide a sofa component to simplify the structure of the component, improve the aesthetics of the sofa, and improve production efficiency and reduce production costs.

[0006] According to one aspect of the present invention, there is provided a sofa assembly, which includes a main structure, a first leg frame, a second leg frame and a backrest. The first leg frame and the second leg frame are arranged on both sides of the main structure along the width direction and are respectively connected to the main structure. The backrest is arranged between the first leg frame and the second leg frame and is respectively connected to the rear ends of the first leg frame and the second leg frame. The first leg frame has a first support and two first support feet, and the two first support feet are respectively arranged at both ends of the first support along the length direction. The first leg frame is provided with at least one first connecting portion. The second leg frame has a second support and two second support feet, and the two second support feet are respectively arranged at both ends of the second support along the length direction. The second leg frame is provided with at least one second connecting portion.

[0007] According to the above solution, compared with the traditional wooden support frame, the sofa assembly has fewer components and the component structure is relatively simple, thus simplifying the assembly process, and can realize automatic assembly by a manipulator or can be completed without professional personnel.

[0008] By respectively providing the first connecting portion and the second connecting portion on the first leg frame and the second leg frame on both sides of the sofa assembly, rapid connection and disassembly between two adjacent sofa assemblies can be realized. Therefore, the assembly process of the sofa can be simplified, production efficiency can be improved and costs can be reduced.

[0026] According to the above several solutions, by providing a first connecting portion on one side of the first side sofa component, rapid connection and disassembly between it and the second connecting portion on the adjacent sofa component can be achieved. Therefore, it is very simple to complete the connection between two adjacent sofa components by sliding the second connecting portion on the adjacent sofa component along the sliding section of the first connecting portion into the locking section. Furthermore, the assembly process of the sofa can be simplified, production efficiency can be improved, and costs can be reduced.

[0027] Moreover, when the second connecting portion is already connected in place, the stop portion in the first connecting portion can also prevent the second connecting portion from accidentally disengaging from the first connecting portion or restrict the upward movement of the second connecting portion along the height direction.

[0028] According to another aspect of the present invention, a second side sofa component is further provided, which includes a main body structure, a first footrest, a second footrest, and a backrest.

What is described here is only the preferred implementation manners of the present invention. Those skilled in the art can think of other ways to implement the present invention based on the preferred implementation manners, and such other ways also fall within the scope of the present invention.

[0074] It should be noted that the directional terms "upper", "lower", "left", "right", "front", "rear", "above", "below", "in front", "at the back", "front end", "rear end", "left side", and "right side" used in this article only refer to relative directions, and their purpose is to more clearly describe various exemplary embodiments provided by the present invention, rather than aiming to limit or restrict the present invention.

[0075] Figure 1 and Figure 2 Fig. shows a perspective view of a sofa assembly 100 according to an exemplary embodiment of the present invention. The sofa assembly 100 includes a main body structure 1, a first leg 2, a second leg 3, and a backrest 4.

[0076] The first leg 2 and the second leg 3 can be selected from one or more of metal parts, blow molded parts, injection molded parts, extrusion molded parts, and wood plastic parts. When the first leg 2 and the second leg 3 are metal parts, they can be made of one or more metal materials such as iron, aluminum, and their alloys through a stamping process. When the first leg 2 and the second leg 3 are non-metal parts, they can be made of one or more non-metal materials such as thermoplastic materials like polyethylene, polyvinyl chloride, polypropylene, and polyester through blow molding, injection molding, extrusion molding, or wood plastic molding processes.

[0077] For the convenience of describing the exemplary embodiments of the present invention, the length direction, width direction, and height direction of the sofa assembly 100 are respectively marked as D1, D2, and D3. Moreover, the length directions of the main body structure 1, the first leg 2, and the second leg 3 are parallel to the length direction D1 of the sofa assembly 100, the width direction of the main body structure 1 is parallel to the width direction D2 of the sofa assembly 100, and the height directions of the main body structure 1, the first leg 2, and the second leg 3 are parallel to the height direction D3 of the sofa assembly 100.

[0078] As shown in the figure, when viewed from above the sofa assembly 100, the main body structure 1 is generally in a rectangular shape. Along the length direction D1, the main body structure 1 has a front F and a rear B. The first leg 2 and the second leg 3 are respectively arranged on both sides of the main body structure 1 along the width direction D2 and are connected to the main body structure 1. The backrest 4 is arranged between the first leg 2 and the second leg 3 and is located at the rear B of the main body structure 1, and the backrest 4 is respectively connected to the rear ends of the first leg 2 and the second leg 3. The front ends of the first leg 2 and the second leg 3 are both close to the front F of the main body structure 1, while the rear ends of the first leg 2 and the second leg 3 are both close to the rear B of the main body structure 1. The above-mentioned front, rear, front end, and rear end all refer to the orientations recognized when the user is sitting on the sofa assembly 100, and the same applies to the left side and the right side mentioned in this specification.

[0079] Preferably, the first leg 2 and the second leg 3 can be connected to the main body structure 1 integrally by riveting.

[0080] Compared with the traditional wooden support frame, the sofa assembly 100 provided by the present invention has fewer components and a relatively simple component structure, thus simplifying the assembly process and enabling automated assembly by a manipulator or completion without professional personnel. Moreover, the first leg 2 and the second leg 3 can be industrially produced automatically through stamping, blow molding, injection molding, extrusion molding, or wood-plastic molding, which avoids traditional wood board processing and can also improve the aesthetics of the product and ensure the excellent rate of the product. Therefore, the cost is reduced, and the production efficiency and product quality are improved.

[0081] Meanwhile, the first leg 2 and the second leg 3 are integrally connected to the main body structure 1 by riveting, so that they can be directly used without assembly by workers, thus further improving the production efficiency and reducing the labor cost.

[0082] Now refer to Figure 3 and Figure 4 , the first leg 2 has a first bracket 21 and two first support feet 22a, 22b. The first bracket 21 and the two first support feet 22a, 22b are preferably integrally formed using metal parts. The first bracket 21 extends along the length direction D1. The two first support feet 22a, 22b are respectively located at the front end and the rear end of the first bracket 21 along the length direction D1. Along the height direction D3, the upper edges of the first bracket 21 and the two first support feet 22a, 22b are aligned, and the heights of the two first support feet 22a, 22b are equal and greater than the height of the first bracket 21. Therefore, when the first leg 2 is placed vertically on the ground, the two first support feet 22a, 22b first contact the ground, so that the first bracket 21 can be suspended above the ground.

[0083] The first leg 2 may further have at least one first fixing portion 23. The first fixing portion 23 is configured to be able to fix the first leg 2 to the main body structure 1. In an exemplary embodiment of the present invention, the first leg 2 has two first fixing portions 23 spaced along the length direction D1 on the first bracket 21. The first fixing portion 23 is recessed from the outside to the inside of the first leg 2 along the width direction D2, and a recess is formed on the outside, and a protrusion is formed on the inside. The outside of the first leg 2 refers to the side of the first leg 2 that is away from the main body structure 1 along the width direction D2. The inside of the first leg 2 refers to the side of the first leg 2 that is close to the main body structure 1 along the width direction D2. Preferably, the contour of the first fixing portion 23 can be rectangular.

[0084] As shown in the figure, the two first fixing parts 23 are respectively a first upper fixing part 23a close to the first support leg 22a and a first lower fixing part 23b close to the first support leg 22b. Among them, the first upper fixing part 23a intersects with the upper edge 24a of the first tripod 2, so an opening is formed at the upper edge 24a. Similarly, the first lower fixing part 23b intersects with the lower edge 24b of the first tripod 2, so an opening is also formed at the lower edge 24b. The first upper fixing part 23a and the first lower fixing part 23b can also be respectively provided with at least one through hole for fixing them to the main body structure 1.

[0085] The first tripod 2 can also be provided with at least one reinforcing rib. The reinforcing rib is recessed from the outside to the inside of the first tripod 2 along the width direction D2, and a concave part is formed on the outside, while a convex part is formed on the inside. And the reinforcing rib can extend along the length direction D1, along the height direction D3 or along a direction at an angle to the length direction D1 on at least a part of the first tripod 2. The shape of the reinforcing rib can be linear, bent, curved, triangular, rectangular, polygonal or other shapes.

[0086] As shown in the figure, the first tripod 2 has reinforcing ribs 25a, 25b and 25c. Among them, the reinforcing rib 25a is located at the joint of the first bracket 21 and the first support leg 22a, and extends from the first support leg 22a to the first bracket 21 along a direction at an angle to the length direction D1. The reinforcing rib 25b extends along the length direction D1 on a part of the first bracket 21. Preferably, the reinforcing rib 25b extends from a position close to the first upper fixing part 23a to the vicinity of the first support leg 22b. And the reinforcing rib 25b is located on the side of the first lower fixing part 23b close to the upper edge 24a. The reinforcing rib 25c is located at the joint of the first bracket 21 and the first support leg 22b, and extends from the first support leg 22b to the first bracket 21 along a direction at an angle to the length direction D1.

[0087] Preferably, at least one of the two first support legs 22a, 22b can also be provided with a reinforcing rib.

[0088] In addition, the first tripod 2 can also have at least one first connecting part 26 detachably connected to an adjacent tripod. For example, as shown in the figure, the first tripod 2 has two first connecting parts 26 spaced along the length direction D1. One first connecting part 26 is located at the first support leg 22a, and the other first connecting part 26 is located at the first support leg 22b. The first connecting part 26 extends from the outside to the inside of the first tripod 2, and also intersects with the upper edge 24a of the first tripod 2 and thus forms an opening at the upper edge 24a, so that the first connecting part 26 forms a notch penetrating along the width direction D2 on the first tripod 2.

[0089] As an exemplary embodiment of the present invention, the first connecting portion 26 may have a sliding-in section 261 and a locking section 262. The sliding-in section 261 extends from the opening at the upper edge 24a in a direction at an angle with respect to the height direction D3 towards the inside of the first support leg 22a or the first support leg 22b, and after extending a certain distance, it changes to continue extending along the height direction D3, thereby forming the locking section 262 below the sliding-in section 261. The sliding-in section 261 and the locking section 262 communicate with each other. Moreover, the notch width formed by the sliding-in section 261 may be greater than the notch width formed by the locking section 262, so that the part on the adjacent tripod that cooperates with the first connecting portion 26 can more easily enter the sliding-in section 261.

[0090] Preferably, the first connecting portion 26 may further have a stop portion 263. The stop portion 263 may be provided in the transition region between the sliding-in section 261 and the locking section 262. As shown in the figure, the stop portion 263 may be a protrusion extending along the length direction D1, and it is configured to be able to reduce the notch width of the transition region between the sliding-in section 261 and the locking section 262.

[0091] Now referring to Figures 5 to 7 , the second tripod 3 has a second bracket 31 and two second support legs 32a, 32b. The second bracket 31 and the two second support legs 32a, 32b are preferably integrally formed using metal parts. The second bracket 31 extends along the length direction D1. The two second support legs 32a, 32b are respectively located at the front end and the rear end of the second bracket 31 along the length direction D1. Along the height direction D3, the upper edge of the second bracket 31 and the upper edges of the two second support legs 32a, 32b are aligned, and the heights of the two second support legs 32a, 32b are equal and greater than the height of the second bracket 31. Therefore, when the second tripod 3 is placed vertically on the ground, the two second support legs 32a, 32b first contact the ground, so that the second bracket 31 can be suspended above the ground.

[0092] Therefore, when the assembled sofa assembly 100 is placed vertically on the ground, the two first support legs 22a, 22b of the first tripod 2 and the two second support legs 32a, 32b of the second tripod 3 will first contact the ground, thereby enabling the main body structure 1 to be suspended above the ground.

[0093] Continuing to refer to Figures 5 to 7, the second tripod 3 may further have at least one second fixing portion 33. The second fixing portion 33 is configured to be able to fix the second tripod 3 to the main body structure 1. In an exemplary embodiment of the present invention, the second tripod 3 has two second fixing portions 33 spaced along the length direction D1 on the second bracket 31. The second fixing portion 33 is recessed from the outer side to the inner side of the second tripod 3 along the width direction D2, and a recess is formed on the outer side, while a protrusion is formed on the inner side. The outer side of the second tripod 3 refers to the side of the second tripod 3 that is away from the main body structure 1 along the width direction D2. The inner side of the second tripod 3 refers to the side of the second tripod 3 that is close to the main body structure 1 along the width direction D2. Preferably, the contour of the second fixing portion 33 may be rectangular.

[0094] Further, the two second fixing portions 33 are respectively a second upper fixing portion 33a close to the second support leg 32a and a second lower fixing portion 33b close to the second support leg 32b. Among them, the second upper fixing portion 33a intersects with the upper edge 34a of the second tripod 3, so an opening is formed at the upper edge 34a. Similarly, the second lower fixing portion 33b intersects with the lower edge 34b of the second tripod 3, so an opening is also formed at the lower edge 34b. The second upper fixing portion 33a and the second lower fixing portion 33b may also be respectively provided with at least one through hole for fixing them to the main body structure 1.

[0095] Preferably, the second fixing portion 33 may be disposed opposite to the first fixing portion 23 in the width direction D2.

[0096] The second tripod 3 may also be provided with at least one reinforcing rib. The reinforcing rib is recessed from the outer side to the inner side of the second tripod 3 along the width direction D2, and a recess is formed on the outer side, while a protrusion is formed on the inner side. And, the reinforcing rib may also extend on at least a part of the second tripod 3 along the length direction D1, along the height direction D3, or along a direction at an angle to the length direction D1. The shape of the reinforcing rib may be linear, bent, curved, triangular, rectangular, polygonal or other shapes.

[0097] As shown in the figure, the second tripod 3 has reinforcing ribs 35a, 35b and 35c. Among them, the reinforcing rib 35a is located at the joint of the second bracket 31 and the second support leg 32a, and extends from the second support leg 32a to the second bracket 31 along a direction at an angle to the length direction D1. The reinforcing rib 35b extends along the length direction D1 on a part of the second bracket 31. Preferably, the reinforcing rib 35b extends from a position close to the second upper fixing portion 33a to near the second support leg 32b. And, the reinforcing rib 35b is located on the side of the second lower fixing portion 33b close to the upper edge 34a. The reinforcing rib 35c is located at the joint of the second bracket 31 and the second support leg 32b, and extends from the second support leg 32b to the second bracket 31 substantially along the length direction D1.

[0098] Preferably, at least one of the two second support feet 32a and 32b may also be provided with a reinforcing rib.

[0099] As Figure 2 and Figure 7 shown, the second tripod 3 may further have at least one second connecting portion 36 disposed opposite to the first connecting portion 26 along the width direction D2. The first connecting portion 26 and the second connecting portion 36 may be configured to have a matching number and be detachably connected to each other.

[0100] For example, the second tripod 3 may have two second connecting portions 36 disposed at intervals along the length direction D1. One of the second connecting portions 36 is located at the second support foot 32a, and the other second connecting portion 36 is located at the second support foot 32b.

[0101] As Figure 8 shown, the second connecting portion 36 has a head 361, a first rod body 362, and a second rod body 363 disposed in sequence along its own length direction. Among them, the head 361, the first rod body 362, and the second rod body 363 may all have a cylindrical shape. And, the diameter of the head 361 is greater than the diameter of the first rod body 362. The diameter of the first rod body 362 may also be greater than the diameter of the second rod body 363, thereby forming a stepped portion 364 between the first rod body 362 and the second rod body 363. An external thread (not shown) may also be provided on the second rod body 363 to cooperate with the fixing hole 39 on the second tripod 3, thereby mounting the second connecting portion 36 to the second tripod 3. Preferably, the diameter of the head 361 of the second connecting portion 36 is greater than the notch width of the locking section 262 of the first connecting portion 26 to prevent the head 361 from passing through the locking section 262 along the width direction D2.

[0102] To facilitate the understanding of the detachable connection between the first connecting portion 26 and the second connecting portion 36, the process of connecting the second connecting portion 36 to the first connecting portion 26 and the process of removing the second connecting portion 36 from the first connecting portion 26 will be described exemplarily below.

[0103] When connecting the second connecting portion 36 to the first connecting portion 26, first place the second connecting portion 36 above the first connecting portion 26. At this time, the first rod body 362 of the second connecting portion 36 is aligned with the notch of the first connecting portion 26, and the head 361 of the second connecting portion 36 is located inside the first tripod 2; then make the first rod body 362 enter the sliding section 261 through the notch and slide obliquely downward along the sliding section 261; finally, slide the first rod body 362 into the locking section 262, thereby completing the connection between the second connecting portion 36 and the first connecting portion 26.

[0104] The process of removing the second connecting portion 36 from the first connecting portion 26 is the reverse of the above-mentioned connecting process, which will not be elaborated here.

[0105] By respectively providing the first connecting portion 26 and the second connecting portion 36 which are detachably connected on the first leg 2 and the second leg 3 on both sides of the sofa assembly 100, rapid connection and disassembly between two adjacent sofa assemblies can be achieved. Therefore, the connection between two adjacent sofa assemblies can be very simply completed by sliding the second connecting portion 36 into the first connecting portion 26. Furthermore, the assembly process of the sofa can be simplified, production efficiency can be improved and costs can be reduced.

[0106] Moreover, when the second connecting portion 36 is already connected in place, the stop portion 263 in the first connecting portion 26 can also prevent the second connecting portion 36 from accidentally disengaging from the first connecting portion 26, or restrict the upward movement of the second connecting portion 36 along the height direction D3.

[0107] Meanwhile, when the first connecting portion 26 and the second connecting portion 36 are already connected in place, the head 361 of the second connecting portion 36 is located inside the first leg 2. Since the diameter of the head 361 is larger than the size of the locking section 262, the head 361 can also restrict the movement of the second connecting portion 36 along the width direction D2 relative to the first connecting portion 26. Therefore, a firm connection between two adjacent sofa assemblies can be ensured. In addition, the first leg 2 may further have at least one fixing hole 28, and the second leg 3 may further have at least one fixing hole 38 which is disposed opposite to the at least one fixing hole 28 along the width direction D2. The fixing holes 28, 38 are used to connect the first leg 2 and the second leg 3 to the main body structure 1 respectively. Preferably, the first leg 2 and the second leg 3 are respectively connected to the torsion-resistant tube of the main body structure 1 through the fixing holes 28, 38 to prevent the sofa assembly 100 from being distorted.

[0108] Back to Figures 1 to 6 , the sofa assembly 100 may further include a pair of backrest fixing members 5, 5'. Among them, the backrest fixing member 5 is fixed to the inner side of the rear end of the first leg 2 through the mounting hole 27 provided on the first support leg 22b of the first leg 2, while the backrest fixing member 5' is fixed to the inner side of the rear end of the second leg 3 through the mounting hole 37a provided on the second support leg 32b of the second leg 3. Both ends of the backrest 4 along the width direction D2 are respectively connected to the pair of backrest fixing members 5, 5'.

[0109] As Figure 9 and Figure 10As shown, the backplane fixing member 5 has an intermediate portion 51 and a first bending section 52 and a second bending section 53 respectively located at both ends of the intermediate portion. The intermediate portion 51 is generally in an "L" shape. Specifically, the intermediate portion 51 has a horizontal section 511 and an inclined section 512. The horizontal section 511 can extend along the length direction D1 or along a direction at an angle to the length direction D1, and the inclined section 512 can extend along the height direction D3 or along a direction at an angle to the height direction D3. Among them, the inclined section 512 is located above or obliquely above the horizontal section 511. And one end of the inclined section 512 is connected to one end of the horizontal section 511 to form an "L" shape. The first bending section 52 is located at the other end of the horizontal section 511 and extends a distance along the width direction D2 from this other end. The second bending section 53 is located at the other end of the inclined section 512 and extends a distance along the width direction D2 in the same direction as the first bending section 52 from this other end. In addition, the angle between the horizontal section 511 and the inclined section 512 of the intermediate portion 51 can be equal to 90 degrees or greater than 90 degrees. As shown in the figure, as an example, the horizontal section 511 extends along a direction at an acute angle to the length direction D1, and the inclined section 512 extends along a direction at an obtuse angle to the length direction D1. At the same time, the angle between the horizontal section 511 and the inclined section 512 is greater than 90 degrees.

[0110] The intermediate portion 51 is further provided with at least one leg mounting hole 513 for connecting the backplane fixing member 5 to the first leg 2. The leg mounting holes 513 can correspond one-to-one with the mounting holes 27 on the first leg 2. As shown in the figure, the number of leg mounting holes 513 is two, and they are respectively located on the horizontal section 511 and the inclined section 512 of the intermediate portion 51.

[0111] The intermediate portion 51 can also be provided with at least one reinforcing rib 514. The reinforcing rib 514 is recessed from the outside to the inside of the backplane fixing member 5 along the width direction D2, and forms a recess on the outside and a protrusion on the inside. And the reinforcing rib 514 can extend on at least a part of the intermediate portion 51 along the length direction D1, along the height direction D3 or along a direction at an angle to the length direction D1. The shape of the reinforcing rib 514 can be linear, bent, curved, triangular, rectangular, polygonal or other shapes. As shown in the figure, as an example, the intermediate portion 51 has a reinforcing rib 514 provided on the inclined section 512. The reinforcing rib 514 is in a triangular shape.

[0112] The backrest fixing member 5 further has at least one main structure mounting hole 521 provided on the first bent section 52 and at least one backrest mounting hole 531 provided on the second bent section 53. The main structure mounting hole 521 is used to connect the backrest fixing member 5 to the main structure 1. The backrest mounting hole 531 is used to connect the backrest fixing member 5 to the backrest 4. Furthermore, the backrest fixing member 5 connects the main structure 1, the first leg 2, and the backrest 4 into one body. As shown in the figure, in the exemplary embodiment of the present invention, the number of the main structure mounting holes 521 is one. The number of the backrest mounting holes 531 is two, and they are spaced apart and distributed on the second bent section 53.

[0113] The backrest fixing member 5' has a structure and shape similar to those of the backrest fixing member 5, and the two are symmetrical or mirror images of each other in the width direction D2. Through the backrest fixing member 5', the main structure 1, the second leg 3, and the backrest 4 can be connected into one body. It should be understood that all the features and their variants described above for the backrest fixing member 5 can be applied to the backrest fixing member 5'. Therefore, they will not be elaborated here.

[0114] Next, the first side sofa assembly 200 and the second side sofa assembly 300 provided by the present invention will be described exemplarily. Those skilled in the art should understand that all the features and their variants described in the exemplary embodiment of the above sofa assembly 100 can be applied to the first side sofa assembly 200 and the second side sofa assembly 300 to be described below. As Figure 11 and Figure 12 shown, the present invention also provides a first side sofa assembly 200, which includes a main structure 1, a first leg 2, a second leg 3, and a backrest 4. The first side sofa assembly 200 has a structure similar to that of the above sofa assembly 100, and the main difference between the two is that the second connecting portion 36 is not provided on the second leg 3 of the first side sofa assembly 200, as Figure 5 , Figure 6 and Figure 12 shown.

[0115] Specifically, the first leg 2 and the second leg 3 are arranged on both sides of the main structure 1 along the width direction D2 and are respectively connected to the main structure 1. The backrest 4 is arranged between the first leg 2 and the second leg and is located behind the main structure 1 in the rear direction B, and the backrest 4 is respectively connected to the rear ends of the first leg 2 and the second leg 3.

[0116] Meanwhile, referring to Figures 3 to 6, the first tripod 2 has a first support 21 extending along the length direction D1 and two first support feet 22a, 22b located at the front end and the rear end of the first support 21 along the length direction D1 respectively. The first tripod 2 also has two first fixing parts 23 spaced along the length direction D1 on the first support 21. Along the length direction D1, two first connecting parts 26 configured to be detachably connected to the second connecting part 36 of the adjacent sofa assembly are further provided on the first tripod 2.

[0117] The second tripod 3 has a second support 31 extending along the length direction D1 and two second support feet 32a, 32b located at the front end and the rear end of the second support 31 along the length direction D1 respectively. The second tripod 3 also has two second fixing parts 33 spaced along the length direction D1 on the second support 31.

[0118] The first tripod 2 and the second tripod 3 may also be respectively provided with at least one reinforcing rib. The reinforcing rib is recessed from the outside to the inside of the first tripod 2 or the second tripod 3 along the width direction D2, and a concave part is formed on the outside, while a convex part is formed on the inside. And the reinforcing rib may extend along at least a part of the first tripod 2 or the second tripod 3 along the length direction D1, along the height direction D3 or along a direction at an angle to the length direction D1. The shape of the reinforcing rib may be linear, bent, curved, triangular, rectangular, polygonal or other shapes.

[0119] The first connecting part 26 has a sliding-in section 261 and a locking section 262. The sliding-in section 261 extends from the opening at the upper edge 24a along a direction at an angle to the height direction D3 towards the inside of the first support foot 22a or the first support foot 22b, and after extending a certain distance, it changes to continue extending along the height direction D3, thereby forming the locking section 262 located below the sliding-in section 261. The sliding-in section 261 and the locking section 262 communicate with each other. And the width of the notch formed by the sliding-in section 261 may be greater than the width of the notch formed by the locking section 262, so that the second connecting part 36 of the adjacent sofa assembly can more easily enter the sliding-in section 261.

[0120] The first connecting part 26 may also have a stop part 263. The stop part 263 may be provided in the transition area between the sliding-in section 261 and the locking section 262. The stop part 263 may be a convex part extending along the length direction D1, and it is configured to be able to reduce the width of the notch in the transition area between the sliding-in section 261 and the locking section 262.

[0121] By providing a first connecting portion 26 on one side of the first side sofa assembly 200, quick connection and disconnection between the first connecting portion 26 and the second connecting portion 36 on an adjacent sofa assembly can be achieved. Thus, it is very simple to complete the connection between two adjacent sofa assemblies by sliding the second connecting portion 36 on the adjacent sofa assembly along the sliding-in section 261 of the first connecting portion 26 into the locking section 262. Furthermore, the assembly process of the sofa can be simplified, production efficiency can be improved, and costs can be reduced.

[0122] Moreover, when the second connecting portion 36 is already connected in place, the stop portion 263 in the first connecting portion 26 can also prevent the second connecting portion 36 from accidentally disengaging from the first connecting portion 26, or restrict the upward movement of the second connecting portion 36 along the height direction D3.

[0123] The first side sofa assembly 200 may also include other backrest fixing members having shapes different from those of the above-described backrest fixing members 5 and 5'.

[0124] For example, as shown in the figure, the first side sofa assembly 200 includes a backrest fixing member 6 and a backrest fixing member 5 as described in the exemplary embodiment of the sofa assembly 100. Among them, the backrest fixing member 5 is fixed to the inner side of the rear end of the first leg frame 2 through the mounting hole 27 provided on the first support leg 22b of the first leg frame 2, while the backrest fixing member 6 is fixed to the outer side of the rear end of the second leg frame 3 through the mounting holes 37a and 37b provided on the second support leg 32b of the second leg frame 3. Both ends of the backrest 4 along the width direction D2 are respectively connected to the backrest fixing member 5 and the backrest fixing member 6. The backrest fixing member 6 can not only be used to connect the backrest 4, but also be used to improve the aesthetics of the sofa when the sofa assembly 200 is arranged on the outermost side of the entire sofa.

[0125] As Figure 13 and Figure 14 shown, the backrest fixing member 6 has a main body 61 and a bent section 62. Among them, the main body 61 is generally in the shape of a flat plate, and the bent section 62 is connected to a part of the contour of the main body 61 and extends a distance along the width direction D2. The main body 61 has a vertical section 611 extending generally along the height direction D3 and an inclined section 612 inclined with respect to the vertical section 611. One end of the vertical section 611 is connected to one end of the inclined section 612. The bent section 62 is located on at least a part of the other end of the inclined section 612.

[0126] The main body 61 is further provided with at least one tripod mounting hole 613 for connecting the backrest fixing member 6 to the second tripod 3. The tripod mounting holes 613 can correspond one-to-one with the mounting holes 37a, 37b on the second tripod 3. The main body 61 can also be provided with at least one reinforcing rib 614. The reinforcing rib 614 is recessed from the outside to the inside of the backrest fixing member 6 along the width direction D2, and a concave portion is formed on the outside, while a convex portion is formed on the inside. And the reinforcing rib 614 can extend on at least a part of the main body 61 along the length direction D1, along the height direction D3 or along a direction at an angle to the length direction D1. The shape of the reinforcing rib 614 can be linear, bent, curved, triangular, rectangular, polygonal or other shapes. As shown in the figure, as an example, one reinforcing rib 614 extends from the vertical section 611 of the main body 61 to the inclined section 612 along a direction at an angle to the height direction D3. The reinforcing rib 614 is linear. Preferably, the extending direction of the reinforcing rib 614 is the same as the inclined direction of the inclined section 612 relative to the vertical section 611.

[0127] The backrest fixing member 6 also has at least one backrest mounting hole 621 provided on the bent section 62. The backrest mounting hole 621 is used to connect the backrest fixing member 6 to the backrest 4. Further, the second tripod 3 and the backrest 4 are connected as a whole. As shown in the figure, the number of the backrest mounting holes 621 is two, and they are spaced apart on the bent section 62.

[0128] Return to Figure 12 The first side sofa assembly 200 can further include a decorative member 7 in addition to the backrest fixing member 5 and the backrest fixing member 6. The decorative member 7 is fixed to the outer front end of the second tripod 3 through the mounting hole 37c provided on the second support leg 32a of the second tripod 3. The decorative member 7 can be used to cover the fixing hole 39 when the second tripod 3 is not provided with the second connecting portion 36, thereby improving the aesthetics of the sofa assembly.

[0129] Now refer to Figure 15 and Figure 16 The decorative member 7 is in the shape of a flat plate and generally has an "L" shape. The decorative member 7 has a horizontal section 71 extending along the length direction D1 and a vertical section 72 extending generally along the height direction D3 or along a direction at an angle to the height direction D3. The angle between the horizontal section 71 and the vertical section 72 can be less than 90 degrees, equal to 90 degrees or greater than 90 degrees. Preferably, the angle between the horizontal section 71 and the vertical section 72 is less than 90 degrees.

[0130] The decorative member 7 is provided with at least one tripod mounting hole 73 for connecting the decorative member 7 to the second tripod 3. As shown in the figure, the decorative member 7 has three tripod mounting holes 73 that can correspond one-to-one with the mounting holes 37c of the second tripod 3.

[0131] AsFigure 17 and Figure 18 As shown in Figure 18 , the present invention further provides a second side sofa assembly 300, which includes a main structure 1, a first footrest 2, a second footrest 3, and a backrest 4. The second side sofa assembly 300 has a similar structure to the above-mentioned sofa assembly 100, and the main difference between the two is that the first connecting portion 26 is not provided on the first footrest 2 of the second side sofa assembly 300.

[0132] Specifically, the first footrest 2 and the second footrest 3 are arranged on both sides of the main structure 1 along the width direction D2 and are respectively connected to the main structure 1. The backrest 4 is arranged between the first footrest 2 and the second footrest 3 and is located behind the main structure 1 in the B direction, and the backrest 4 is respectively connected to the rear ends of the first footrest 2 and the second footrest 3.

[0133] Referring also to Figures 3 to 7 , the first footrest 2 has a first bracket 21 extending along the length direction D1 and two first support feet 22a, 22b located at the front end and the rear end of the first bracket 21 respectively along the length direction D1. The first footrest 2 further has two first fixing portions 23 arranged at intervals along the length direction D1 on the first bracket 21. The second footrest 3 has a second bracket 31 extending along the length direction D1 and two second support feet 32a, 32b located at the front end and the rear end of the second bracket 31 respectively along the length direction D1. The second footrest 3 further has two second fixing portions 33 arranged at intervals along the length direction D1 on the second bracket 31.

[0134] The first footrest 2 and the second footrest 3 may also be respectively provided with at least one reinforcing rib. The reinforcing rib is recessed from the outside to the inside of the first footrest 2 or the second footrest 3 along the width direction D2, and a concave portion is formed on the outside, and at the same time, a convex portion is formed on the inside. And the reinforcing rib may extend along at least a part of the first footrest 2 or the second footrest 3 along the length direction D1, along the height direction D3, or along a direction forming an angle with the length direction D1. The shape of the reinforcing rib may be linear, bent, curved, triangular, rectangular, polygonal, or other shapes.

[0135] Preferably, the first footrest 2 may have a structure and shape similar to those of the second footrest 3. For example, the first footrest 2 is symmetric or mirror-image to each other with respect to the second footrest 3 in the width direction D2.

[0136] Along the length direction D1, two second connecting portions 36 are further provided on the second footrest 3 and are configured to be detachably connected to the first connecting portion 26 of the adjacent sofa assembly. As Figure 8As shown, the second connecting portion 36 has a head 361, a first rod body 362, and a second rod body 363 that are sequentially arranged along its own length direction. Among them, the head 361, the first rod body 362, and the second rod body 363 may all have a cylindrical shape. And, the diameter of the head 361 is greater than the diameter of the first rod body 362. The diameter of the first rod body 362 may also be greater than the diameter of the second rod body 363, thereby forming a stepped portion 364 between the first rod body 362 and the second rod body 363. An external thread may also be provided on the second rod body 363 to cooperate with the fixing hole 39 on the second tripod 3, thereby installing the second connecting portion 36 onto the second tripod 3. The diameter of the head 361 of the second connecting portion 36 is greater than the notch width of the locking section 262 of the first connecting portion 26 to prevent the head 361 from passing through the locking section 262 along the width direction D2. The second side sofa assembly 300 may further include a backrest fixing member 5' as described in the exemplary embodiment of the sofa assembly 100, which is provided on the second support leg 32b of the second tripod 3 for connecting the main body structure 1 and the backrest 4.

[0137] The second side sofa assembly 300 may further include a backrest fixing member 6' and a decorative member 7'. The backrest fixing member 6' and the decorative member 7' may respectively have structures and shapes similar to those of the backrest fixing member 6 and the decorative member 7 described in the exemplary embodiment of the first side sofa assembly 200. The main difference is that the backrest fixing member 6' and the backrest fixing member 6 are symmetric or mirror images of each other in the width direction D2, and the decorative member 7' and the decorative member 7 are symmetric or mirror images of each other in the width direction D2.

[0138] By providing the second connecting portion 36 on one side of the second side sofa assembly 300, quick connection and disassembly between it and the first connecting portion 26 on the adjacent sofa assembly can be achieved. Therefore, it can be very simply completed by sliding the second connecting portion 36 along the sliding section 261 of the first connecting portion 26 on the adjacent sofa assembly into the locking section 262 to complete the connection between two adjacent sofa assemblies. Furthermore, the assembly process of the sofa can be simplified, production efficiency can be improved, and costs can be reduced.

[0139] In addition, the present invention also provides a sofa, which includes a first side sofa assembly 200 and a second side sofa assembly 300.

[0140] The first side sofa assembly 200 and the second side sofa assembly 300 are arranged side by side and closely along the width direction D2.

Thus, the first side sofa component 200, at least one sofa component 100, and the second side sofa component 300 are installed together along the width direction D2.

[0143] When the sofa includes multiple sofa components 100, the multiple sofa components 100 are connected side by side in sequence and arranged between the first side sofa component 200 and the second side sofa component 300. Among them, in two adjacent sofa components 100, the first connecting portion 26 of one sofa component 100 is detachably connected to the second connecting portion 36 of the other sofa component 100.

[0144] By providing the first connecting portion 26 or the second connecting portion 36 on the sofa component located on the side, connection with the sofa component 100 located in the middle position can be achieved, thereby constituting a complete sofa. The first connecting portion 26 or the second connecting portion 36 on the first side sofa component 200 or the second side sofa component 300 enables them to be quickly connected to the adjacent sofa component 100, thus completing the installation of the entire sofa. This can effectively simplify the assembly process of the sofa, improve production efficiency and reduce labor costs.

[0145] In addition, since sofa components of various different structures are provided, the types and quantities of sofa components can be selected according to different needs, and then multiple sofa components can be combined into sofas of different lengths to meet different needs.
