Description

Technical Field

[0001] The invention relates to the field of sofas, and in particular to a base support structure and a European-style side sofa base structure. Background Art

[0002] In recent years, European decoration style has become the choice of more and more people who pursue a tasteful life. Even if it is not possible to decorate the entire home in European style, some families also like to buy some exotic furniture to put in their homes, such as European sofas.

[0003] In the traditional European side sofa, the base frame is made of wooden material as a whole, which has the disadvantages of heavy weight, many production processes, troublesome assembly, labor-intensive, high cost, etc., and has great limitations. Summary of the invention

[0004] In order to overcome the defects of the prior art described above, the present invention provides a base support structure and a European-style edge sofa base structure.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] The present invention first provides a base support structure, comprising a first support frame located at the front side and a second support frame located at the rear side, wherein:

[0007] The first support frame includes two first side panels spaced apart from each other and a connecting strip located between the two first side panels and connected to the two first side panels; the two first side panels are respectively used to connect to the connecting rods on both sides of the functional iron frame in the sofa base;

[0008] The second support frame includes two second side panels spaced apart from each other, and the two second side panels are used to connect with the crossbar of the functional iron frame in the sofa base;

[0009] The first side plate, the connecting strip and the second side plate are all metal parts.

[0010] The base support structure of the present invention adopts a first support frame and a second support frame arranged at intervals in front and back to replace the traditional wooden frame, so that the structure is simple and material saving is achieved. In addition, the first side plate, the connecting strip and the second side plate are all metal parts, which not only have high support strength, but also are suitable for assembly line production and have great promotion potential.

[0011] Furthermore, both side edges and the bottom edge of the first side panel are provided with flanges.

[0012] Therefore, providing the flange can enhance the supporting strength of the first side plate.

[0013] Furthermore, the lower end of the first side plate is in an arch shape and includes a first side portion and a second side portion, and both ends of the connecting strip are respectively connected to the first side portions of the two first side plates.

[0014] Furthermore, the bottom of the second side portion of the first side plate and the bottom of the second side plate are both provided with supporting feet.

[0015] Furthermore, the outer panels of the first side panel and the second side panel on the same side are provided with connectors for connecting the sofa armrests, and the outer panels of the first side panel and the second side panel on the other same side are provided with slots or buckles for connecting the middle sofa base.

[0016] Furthermore, a U-shaped positioning piece is provided on the inner side surface of the second side plate, and a mounting groove is provided at the lower end of the positioning piece for the end of the cross bar of the functional iron frame to extend into.

[0017] Thus, by arranging the positioning member, not only the strength of the second side plate can be strengthened, but the positioning member also plays the role of supporting the cross bar. In addition, by arranging the mounting groove at the lower end of the positioning member, the cross bar can be conveniently installed and limited, which is convenient for assembly.

[0018] Furthermore, the connecting strip is a metal square tube.

[0019] In addition, the present invention also provides a European-style side sofa base structure, including the above-mentioned base support structure and a functional iron frame, wherein the functional iron frame includes two connecting rods respectively connected to the two first side panels and a cross bar with two ends respectively connected to the two second side panels.

[0020] Furthermore, it also includes a seat frame rear support plate, and the seat frame rear support plate is connected to the two second side plates.

[0021] Furthermore, the seat frame rear support plate is an integrally formed injection molded part.

[0022] In summary, the base support structure and the European-style side sofa base structure of the present invention use the first support frame and the second support frame arranged at intervals in front and back to replace the traditional wooden frame, so that the structure is simple and material saving is achieved. In addition, the first side panel, the connecting strip and the second side panel are all metal parts, which not only have high support strength, but also are suitable for assembly line production and have great promotion potential.

[0033] Embodiment 1

[0034] See also Figure 1-4The present invention provides a base support structure 1, including a first support frame 11 located at the front side and a second support frame 12 located at the rear side, the first support frame 11 includes two first side panels 111 arranged at a distance from each other on the left and right sides, and a connecting strip 112 located between the two first side panels 111 and connected to the two first side panels 111; the two first side panels 111 are respectively connected to the two side connecting rods 21 of the functional iron frame 2 in the sofa base; the second support frame 12 includes two second side panels 121 arranged at a distance from each other on the left and right sides, and the two second side panels 121 are both connected to the cross bar 22 of the functional iron frame 2 in the sofa base.

[0035] In this embodiment, the first side plate 111 , the connecting bar 112 , and the second side plate 121 are all made of metal.

[0036] Therefore, the base support structure 1 of the present invention uses the first support frame 11 and the second support frame 12 arranged at intervals in front and back to replace the traditional wooden frame, so that the structure is simple and material saving is achieved. In addition, the first side plate 111, the connecting strip 112 and the second side plate 121 are all metal parts, which not only have high support strength, but also are suitable for assembly line production and have great promotion potential.

[0037] See also Figure 1-2 , both sides and the bottom of the first side plate 111 are provided with flanges 1111; the lower end of the first side plate 111 is arched and includes a first side portion 1112 and a second side portion 1113, and both ends of the connecting strip 112 are respectively connected to the first side portions 1112 of the two first side plates 111. In addition, the bottom of the second side portion 1113 of the first side plate 111 and the bottom of the second side plate 121 are provided with legs 13.

[0038] In this embodiment, the connecting bar 112 is a metal square tube; the supporting leg 13 is a cylindrical structure.

[0039] Therefore, providing the flange 1111 and providing the lower end of the first side plate 111 in an arch shape can both improve the supporting strength of the first side plate 111 .

[0040] See also Figure 3 The inner side surface of the second side plate 121 is provided with a U-shaped positioning member 16 , and the lower end of the positioning member 16 is provided with a mounting groove 161 for the end of the cross bar 22 of the functional iron frame 2 to extend into.

[0041] Thus, by providing the positioning member 16, not only can the strength of the second side plate 121 be strengthened, but the positioning member 16 also plays a role in supporting the cross bar 22. In addition, by providing the mounting groove 161 at the lower end of the positioning member 16, the cross bar 22 can be conveniently installed and limited, which is convenient for assembly.

[0042] In this embodiment, the positioning member 16 and the second side plate 121 are fixed together by bolts.
