Description

Technical Field

[0001] This utility model belongs to the field of sofa technology, specifically relating to a sofa inner pocket that prevents the four corners from collapsing. Background Technology

[0002] Sofas are essential furniture pieces in both office and home spaces, occupying a prominent position and playing an indispensable role. Especially in office spaces, sofas are ideal for receiving clients and partners; their comfortable seating and elegant design create a professional and friendly atmosphere for communication. They are a crucial factor in improving the quality of the work environment and boosting work efficiency, as well as enhancing the overall decorative effect and aesthetic value of the space.

[0003] As a crucial element of sofa comfort and aesthetics, the design of the inner pockets of cushions is particularly important. Traditional cushion designs typically consist of the inner pocket itself and the filling material within it. When someone leans against the cushion, the filling material collapses inwards under pressure, leading to filling displacement and sagging at the corners. Ultimately, this reduces the overall comfort and aesthetics of the sofa. Utility Model Content

[0004] To overcome the shortcomings of existing technology, this utility model provides a sofa inner pocket that prevents the four corners from collapsing, thus solving the technical problem of the filling material at the four corners of the inner pocket collapsing under pressure.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A sofa inner pocket designed to prevent corner sagging includes an inner pocket body and four anti-sagging panels. Each anti-sagging panel is positioned at one of the four corners of the inner pocket body's inner cavity. The two side edges of the anti-sagging panels are sewn to the fabric on both sides of the inner pocket body, dividing the inner cavity of the inner pocket body into a corner portion and a center portion.

[0007] Furthermore, the anti-collapse piece is inclinedly arranged inside the inner bag body, forming a 45° angle with the bag opening of the inner bag body.

[0008] Furthermore, the two ends of the anti-collapse cut piece are spaced apart from the sides of the inner bag body.

[0009] Furthermore, the distance between the end of the anti-collapse piece and the side of the inner bag body is 5mm.

[0010] Furthermore, both sides of the inner bag body have open openings. A zipper is provided at the opening of the inner bag body.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention divides the inner cavity of the inner bag body into corner sections and a central section by sewing anti-collapse panels at the four corners. When the inner bag body is compressed during use, the material in the four corner sections remains within the corners due to the anti-collapse panels, preventing the material in the corners from collapsing towards the center under pressure. This improves the overall comfort and aesthetics of the product, thereby enhancing its overall quality and meeting consumers' high expectations. Attached Figure Description

[0016] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a sofa inner pocket designed to prevent corner sagging includes an inner pocket body 1 and four anti-sagging panels 2. Each anti-sagging panel 2 is fixed to one of the four corners of the inner pocket body 1, dividing the inner pocket into corner portions 3 and a central portion 4. Filling material is introduced into the corner portions 3 and the central portion 4 through two openings in the inner pocket body 1, and the openings are sealed after filling.

[0019] When the inner bag body 1 is compressed during use, the material inside the four corners 3 of the inner bag body 1 is retained in the corners 3 by the anti-collapse cutting piece 2, which prevents the material in the four corners 3 from collapsing towards the center under pressure, causing the four corners 3 of the inner bag body 1 to become flat and affecting the aesthetics of the inner bag body 1.

[0020] like Figure 1 and 2As shown, the anti-collapse piece 2 is made of fabric. The two side edges of the anti-collapse piece 2 are sewn to the fabric on both sides of the inner bag body 1. In this embodiment, the edges of the inner bag body 1 are divided into left and right bag opening edges 1-1 and top and bottom side edges 1-2. The anti-collapse piece 2 is obliquely positioned inside the inner bag body 1, forming a 45° angle with the bag opening edges 1-1 of the inner bag body 1.

[0021] Furthermore, the two ends of the anti-collapse piece 2 are spaced apart from the bag opening edge 1-1 and the side edge 1-2, forming a filling channel between the anti-collapse piece 2 and the side edge 1-2 of the inner bag body 1. The material filled between the anti-collapse piece 2 and the side edge 1-2 can fill the center of the inner cavity of the inner bag body 1 through the filling channel, ensuring that the four corners 3 of the inner bag body 1 are full and plump, while reducing the impact of the anti-collapse piece 2 on the material filling.

[0022] In this embodiment, the distance between the two ends of the anti-collapse piece 2 and the bag opening edge 1-1 and the side edge 1-2 is 5mm.

[0023] In addition, in this embodiment, zippers are provided at both edges 1-1 of the inner bag body 1. When material needs to be filled, the worker opens the zipper, making the bag openings on both sides of the inner bag body 1 open. When the material filling is completed, the worker tightens the zipper, making the bag openings on both sides of the inner bag body 1 closed.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
