Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a retractable single sofa. Background Technology

[0002] An upholstered sofa is a type of sofa, primarily consisting of backrests and seats filled with soft materials such as sponge or fabric. Single sofas are narrower than multi-seater sofas, making them suitable for single use and offering the advantage of taking up less space.

[0003] Existing single sofas are either simply a seat and backrest that cannot be unfolded, or reclining sofas that cannot be folded, resulting in limited flexibility. Sometimes, to allow lying flat, an additional cushion is placed directly on the sofa. While this allows for lying flat, the extra cushion is not connected to the sofa, making it prone to separation. Therefore, an improved technology is urgently needed to solve this problem in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide an unfoldable single sofa to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable single sofa, comprising a sofa body, a flip-up body, a cylindrical backrest, and a cushion. The upper surface of the back of the sofa body is provided with a backrest, and an arc-shaped groove is provided at the connection between the backrest and the sofa body. A cushion is connected to one side of the cylindrical backrest. The cylindrical backrest cooperates with the arc-shaped groove and is movably inserted into the arc-shaped groove. The upper surface of the sofa body at the end away from the backrest is connected to the upper surface of the flip-up body at the end of the flip-up body through a connecting fabric. The end of the flip-up body away from the sofa body is an arc-shaped end, and the arc-shaped end of the flip-up body matches the arc-shaped groove.

[0006] Preferably, the present invention provides an unfoldable single sofa in which the sofa body, the flip-up body, the cylindrical backrest and the cushion are all composed of a sponge core and a covering fabric. The connecting fabric is sewn to the covering fabric of the sofa body and the flip-up body respectively, and the covering fabric of the cylindrical backrest and the cushion is sewn to each other.

[0007] Preferably, in the unfoldable single sofa provided by this utility model, one side of the covering fabric of the sofa body, the flip-up body, the cylindrical backrest and the backrest is sealed with a zipper.

[0008] Preferably, in the unfoldable single sofa provided by this utility model, the distance from the connecting fabric to the arc-shaped groove is the same as the distance from the connecting fabric to the arc-shaped end of the flipping body.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a retractable single sofa, including a sofa body 1, a flip-up body 2, a cylindrical backrest 3, and a cushion 4. A backrest 5 is provided on the upper surface of the rear side of the sofa body 1. An arc-shaped groove 6 is provided at the connection between the backrest 5 and the sofa body 1. A cushion 4 is connected to one side of the cylindrical backrest 3. The cylindrical backrest 3 cooperates with and is movably inserted into the arc-shaped groove 6. The upper surface of the sofa body 1 at the end away from the backrest 5 is connected to the upper surface of one end of the flip-up body 2 via a connecting fabric 7. The end of the backrest 5 closest to the flip-up body 2 is... The sloping surface 9 is more ergonomic and improves the comfort of the backrest 5. The distance from the connecting fabric 7 to the arc-shaped groove 6 is the same as the distance from the connecting fabric 7 to the arc-shaped end 8 of the flip body 2. This ensures that when the flip body 2 flips onto the upper surface of the sofa body 1, the outer end of the flip body 2 and the outer end of the sofa body 1 are flush. This prevents the flip body 2 from protruding and causing insufficient support at the outer end, and also prevents the arc-shaped end 8 of the flip body 2 from being unable to be inserted into the arc-shaped groove 6. The arc-shaped end 8 of the flip body 2 is away from the sofa body 1 and matches the arc-shaped groove 6.

[0023] The sofa body 1, the flip-up body 2, the cylindrical cushion 3, and the backrest 4 are all composed of a sponge core and a covering fabric. The use of a sponge core and a covering fabric facilitates the removal of the sponge core and the washing of the covering fabric. The connecting fabric 7 is sewn to the covering fabric of the sofa body 1 and the flip-up body 2 to connect the connecting fabric 7 to the covering fabric of the sofa body 1 and the flip-up body 2. The covering fabric of the cylindrical cushion 3 and the backrest 4 is sewn together to connect the covering fabric of the cylindrical cushion 3 and the backrest 4. One side of the covering fabric of the sofa body 1, the flip-up body 2, the cylindrical cushion 3, and the backrest 4 is sealed with a zipper to facilitate opening the covering fabric and thus disassembling the sponge core.

[0024] Installation Method and Usage Principle: First, prepare the covering fabric and sponge core for the sofa body 1, the flip-up body 2, the cylindrical cushion 3, and the backrest 4. Then, connect the covering fabric of the sofa body 1 and the flip-up body 2 with connecting fabric 7. The connecting fabric 7 is the same material and color as the covering fabric to ensure aesthetics and comfort upon contact. The connecting fabric 7 is sewn to the covering fabric of the sofa body 1 and the flip-up body 2. The cylindrical cushion 3 and the backrest 4 are also sewn together. One side of the covering fabric is sealed with a zipper, which facilitates the filling or removal of the inner core of the sofa body 1, the flip-up body 2, and the cylindrical cushion 3, and makes it convenient for subsequent cleaning of the covering fabric. Stuff the sponge core of the sofa body 1, the flip-up body 2, the cylindrical cushion 3, and the backrest 4 into the corresponding covering fabric. In use, the sofa can be unfolded by lowering the flip-up body 2 parallel to the main sofa body 1. Then, the cylindrical cushion 3 is placed into the arc-shaped groove 6 of the main sofa body 1 to support the backrest 5. At this time, the upper part of the backrest 4 is supported on the inclined surface 9 of the backrest 5, and the lower part is supported on the cylindrical cushion 3. A person can lie on the main sofa body 1 and the flip-up body 2, with their back against the backrest 4. Because it is connected by the connecting fabric 7, the flip-up body 2 will not leave the main sofa body 1. The cylindrical cushion 3 is then pulled out from the arc-shaped groove 6, and the flip-up body 2 is flipped over and overlapped on the main sofa body 1. At the same time, the arc-shaped end 8 of the flip-up body 2 is inserted into the arc-shaped groove 6 of the main sofa body 1. At this time, it becomes a sofa with a higher seat cushion. The backrest 4 can be placed on the backrest 5, and the cylindrical cushion 3 is supported at the top of the backrest 5, which prevents the backrest 4 from falling off the backrest 5. This utility model has a reasonable structure. An arc-shaped groove 6 is provided at the connection between the sofa body 1 and the backrest 5. When the flip-up body 2 is laid flat, the matching cylindrical cushion 3 can be inserted into the arc-shaped groove 6, thus ensuring the support of the backrest 5. The cushion 4 can be supported on the inclined surface 9 of the backrest 5 and the outside of the cylindrical cushion 3, and the cushion 4 will not easily detach from the backrest 5. When the flip-up body 2 is flipped and stacked on the sofa body 1, the arc-shaped end 8 of the flip-up body 2 is inserted into the arc-shaped groove 6, forming a sofa. At this time, the cushion 4 can be supported on the backrest 5, and the cylindrical cushion 3 is supported on the backrest 5. Similarly, the cushion 4 will not easily detach from the backrest 5. Easily detached from the backrest 5, this structure allows for both reclining and sitting, with quick and convenient switching, greatly improving flexibility; and the sofa body 1 and the flip-up body 2 are connected by a connecting fabric 7, so the flip-up body 2 will not detach from the sofa body 1 whether it is laid flat or flipped and stacked; at the same time, the sofa body 1 has an arc-shaped groove 6 at the backrest 5, which can be used with the cylindrical pillow 3 or the arc-shaped end 8 of the flip-up body 2. On the one hand, both forms can ensure the support of the backrest 5, and on the other hand, when the flip-up body 2 is flipped and stacked on the sofa body 1, the stability of the flip-up body 2 is ensured.
