Description

[Technical Field]

[0001] The present invention relates to a sofa that is easy for users to assemble. [Background technology]

[0002] In recent years, there have been cases where customers purchase sofa components via mail order or in stores and have them delivered to their homes, and then assemble them themselves to create a finished sofa that they can then use. For example, the sofa in Patent Document 1 includes a seat panel, front and rear frames fixed to the seat panel, a sofa body made of an elastic material, and legs fixed to the front and rear frames. The front frame is composed of two front base plates and a front connecting plate that connects the ends of the two front base plates, and the two rear base plates and the rear frame are composed of a rear connecting plate that connects the ends of the two rear base plates.

[0003] However, in the technology described in Patent Document 1, the legs cannot be directly attached to the sofa body, and multiple parts such as the front frame and the rear frame must be assembled, and then the four legs must be attached to the bottom plate using attachment members and tools. As a result, the number of parts is large, making assembly difficult for users who are not accustomed to it. Furthermore, the manufacturing side faces the problem of increased manufacturing costs due to the large number of parts involved. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, the sofa of the present invention will be described in detail by taking an embodiment as an example with reference to Figs.

[0010] Embodiment 1 Fig. 1 is a perspective view of a sofa 1 according to this embodiment, and Fig. 2 is a perspective view of a sofa 2 according to this embodiment. Sofa 1 in Figure 1 is a two-seater sofa, and sofa 2 in Figure 2 is the sofa on one side of sofa 1.

[0011] As shown in FIGS. 1 and 2, the sofas 1 and 2 include a sofa body 10, an attachment portion 18, a back cushion 20, a seat cushion 30, a base 40, and legs 50. The sofa body 10 includes a seat 11, armrests 12, and a backrest 13 at the rear. The sofa body 10 is made of fabric 16. Specifically, the sofa body 10 is a square bag-shaped body filled with shock-absorbing cushioning material, and its surface is formed of fabric 16. The sofa body 10 is filled with a structure 14 to enhance cushioning inside. The structure 14 is made of urethane. The surface material of the sofa body 10 may be leather or synthetic leather. The surfaces of the seat cushion 30 placed on the upper surface of the seat 11 of the sofa body 10 and the back cushion 20 are also made of the same surface and interior materials as the sofa body 11.

[0012] As shown in FIG. 6, the inner fabric covering the urethane of the structure 14 is exposed on the underside of the sofa body 10. 6 and 8, at the lower part of the sofa body 10, an end of the fabric (cloth) 16 forms the attachment part 18. The attachment part 18 has the function of fixing the base 40. A fixing means such as a tape (not shown), e.g., a hook-and-loop tape, is attached to the attachment part 18. As shown in FIGS. 6 and 7, the attachment portion 18 is disposed on the underside of the sofa body 10, wraps around the end of the base 40, and is fixed by the fixing means of the attachment portion 18. As another fixing means, the mounting member 18 may be fixed to the base 40 by adhesive. The base 40 is flat and disposed at the bottom of the sofa body 10. The base 40 may be formed of a slatted base or a frame and springs (S-springs and webbing tape). The legs 50 are disposed at the bottom of the base 40. The legs 50 have four legs attached to the underside of the base 40 .

[0013] In Figure 3, (a) is a plan view of the sofa body, (b) is a front view, and (c) is a side view. The sofa 2 in Figures 3(a), (b), and (c) is composed of a urethane part and a base part. As shown by the solid lines in Figures 3(a), (b), and (c), the sofa body 1, back cushion 20, and seat cushion 30 are made of compressed urethane. As shown by the dashed lines in Figures 3(a), (b), and (c), the base part is made of a bottom plate 40 and legs 50.

[0014] Next, a method for assembling the sofa 1 will be described. Fig. 4 is a perspective view showing a state 1 in which the sofa main body etc. is compressed. Fig. 5 is a perspective view showing a state 2 in which the sofa main body etc. is compressed. Fig. 6 is a perspective view showing an assembled state 1 of the sofa. Fig. 7 is a perspective view showing an assembled state 2 of the sofa. Fig. 8 is an exploded perspective view showing the configuration of the sofa.

[0015] As shown in FIG. 4, the sofa body 10, the back cushion 20 and the seat cushion 30 are compressed together using a press (not shown), thereby putting the sofa body etc. into a compressed state 42. Next, as shown in FIG. 5, the sofa body or the like in the compressed state 42 is rolled up in the left and right direction to make the columnar sofa body or the like in the compressed state 43, and can be compressed and packed.

[0016] The sofa 1 is delivered to a purchaser in a compressed state 43, including the sofa body 10. The base 40 is also packaged. When a worker assembling the sofa 1 opens the compressed and packaged sofa body 10, back cushion 20 and seat cushion 30, each of them expands and returns to its original state. After the sofa body 10, the back cushion 20 and the seat cushion 30 are inflated, the sofa can be used as a sofa.

[0017] 6 and 7 show the process of wrapping the base 40 with the fabric (cloth) 16 of the sofa body 10. As shown in FIGS. 6 and 7, the worker attaches the legs 50 to the bottom plate 40 in advance. As shown in Fig. 6, the worker rotates the sofa body 10 to expose its underside. The sofa body 10 is in a state where the inner fabric covering the urethane of the structure 14 is exposed, and the base 40 is aligned with the position of the mounting part 18.

[0018] Next, as shown in Fig. 7, the worker wraps the base 40 around the attachment parts 18 located at the ends of the sofa main body 1 and secures it with hook-and-loop tape (not shown), thereby attaching the base 40 to the sofa main body 10. By wrapping and securing the base 40 at four points of the attachment parts 18, the base 40 can be more stably fixed to the sofa main body 10.

[0019] The worker rotates the sofa body 10 from the state shown in FIG. 7 to raise it up. Finally, the worker places the back cushion 20 and the seat cushion 30 on the sofa body 10 as shown in FIG. 8, thereby completing the assembly of the sofa 1.

[0020] As described above, the sofa of this embodiment is provided with the attachment parts 18 arranged on the underside of the sofa body 10 that houses the deformable structure 16, and the attachment parts 18 can fix the ends of the base 40. Therefore, it is possible to provide a sofa that is easy to transport in an unfinished state, has a small number of parts, and is easy to assemble. As a result, a sofa with excellent design can be provided.

[0021] Although the embodiments of the sofa of the present invention have been described above, the present invention is not limited to the described embodiments, and various modifications can be made within the scope of the claims.

[0022] In the embodiment described above, sofa 1 is a two-seater sofa, but it may also be a one-seater sofa, a sofa that seats three or more people, a stool, a couch sofa, a corner sofa, an island sofa, a chaise longue sofa, or an ottoman.

[0023] In the embodiment described above, urethane is used as the material inside the structure 14 of the sofa body 10, but bead cushions or air cushions may also be used. This allows the sofa to be compressed during packaging, making it easier to transport.

[0024] In the embodiment described above, tape is used as a fastening means for wrapping and fastening the mounting part 18 of the sofa body 10 around the base 40, but zippers, buttons, or strings may also be used. This makes it easier to remove the base 40 from the mounting part 18 and adjust the mounting position. It also improves the design.

[0025] In the embodiment described above, the legs 50 are attached to the base 40, but the sofa may be used as a so-called low sofa in which the legs 50 are not attached to the base 40. This allows the number of parts to be reduced. [Explanation of symbols]
