Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and in particular to a self-packing sofa. Background Technology

[0002] While many sofas on the market now offer flat, modular designs, those that combine product functionality with packaging are relatively rare. Traditional sofa bases typically use wooden frames with ample internal space. This space is often underutilized during packaging and shipping, instead taking up extra volume and usually requiring additional wooden frames for protection. This further increases the space needed for transport and leads to higher logistics costs. Utility Model Content

[0003] This utility model provides a self-packing sofa to solve the problems in the prior art.

[0004] This utility model embodiment adopts the following technical solution: a self-packing sofa, including a sofa state and a transportation state; in the sofa state, the sofa includes a base with a built-in cavity, a backrest detachably installed on the base, and a soft cushion laid on the base; in the transportation state, the backrest is separated from the base and completely placed in the cavity, and the soft cushion is rolled or folded and completely placed in the cavity. This sofa uses the base as an outer shell and transforms it into outer packaging, utilizing its own structure to protect the internal components without the need for a large amount of additional packaging materials.

[0005] Preferably, the base is made of recycled plastic in one piece, which aligns with the design concept of sustainable development.

[0006] Preferably, the outer fabric cover of the backrest or cushion is made of a blend of fibers from recycled plastic waste and natural cotton and linen. This aligns with sustainable development design principles.

[0007] Preferably, the base is rectangular, and the cavity of the base extends through the left and right sides of the base, making it easy to remove the backrest and cushion inserted into the cavity.

[0008] Preferably, the lower end of the base is also equipped with several foot pads. The foot pads are used to support the overall structure of the sofa.

[0009] Preferably, the base has at least one first hole extending into the cavity, and the lower end of the backrest has a corresponding insert block; the insert block is inserted into the first hole, and the backrest abuts against the base. By laterally moving the insert block, at least a portion of the structure on the base is embedded in a slot on the insert block, thereby achieving axial positioning of the backrest relative to the base. Whether installing the backrest onto the base or removing it from the base, the entire process only requires inserting the insert block, laterally moving it, and reversing the operation. The operation steps are simple and easy to understand, requiring no complex tools or professional skills.

[0010] Preferably, the base has at least one second hole extending into the cavity, and a slot communicating with the second hole is located beside it. The cushion is connected to an elastic cord corresponding to each of the second holes, and a retaining ball at the end of the elastic cord. The retaining ball passes through the second hole into the cavity, allowing the elastic cord to enter the slot, so that the retaining ball abuts against the top wall of the cavity. Four sets of elastic cords are configured and connected to the four corners of the cushion, and four corresponding second holes are also configured on the base. Through the cooperation of the elastic cords and retaining balls, the elastic tension of the elastic cords firmly fixes the cushion to the base. This fixing method effectively prevents the cushion from sliding or wrinkling during use, maintaining the cushion's flatness and aesthetics, while also improving the user's comfort while sitting on the sofa.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] This sofa uses its base as an outer shell, transforming it into packaging. Utilizing its own structure, it protects the internal components by concealing the backrest and seat cushions within the base, significantly reducing the packaging volume. During transportation, the same transport vehicle can carry more sofas, improving transport efficiency and reducing unit transportation costs. Furthermore, because the backrest and cushions are housed within the cavity of the base, they receive better protection, reducing damage caused by collisions and friction.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1 to 5 As shown, this utility model embodiment provides a self-packing sofa, including a sofa state and a transport state. In the sofa state, the sofa includes a base 1 with a built-in cavity 11, a backrest 2 detachably mounted on the base 1, and a cushion 3 laid on the base 1. In the transport state, the backrest 2 is separated from the base 1 and completely placed inside the cavity 11, and the cushion 3 is rolled or folded and completely placed inside the cavity 11. Generally, the base 1 is rectangular, and the cavity 11 of the base 1 extends through the left and right sides of the base 1. In the sofa state, the backrest 2 is located at the upper end and rear of the base 1, and the cushion 3 is composed of a first area and a second area. The first area of ​​the cushion 3 is laid flat on the upper end of the base 1 and abuts against the backrest 2, and the second area of ​​the cushion 3 is perpendicular to the first area and vertically abuts against the front end of the base 1.

[0024] Sofa condition: See reference Figures 1 to 2 As shown, during normal use, the backrest 2 is installed on the base 1, and a soft cushion 3 is placed on the base 1 to form a sofa for sitting and leaning against. Transportation status: Refer to... Figures 3 to 4As shown, when the sofa needs to be transported or stored, the backrest 2 is removed from the base 1, the cushion 3 is removed from the base 1, and then the backrest 2 and the rolled-up or folded cushion 3 are placed into the built-in cavity 11 of the base 1. Since the backrest 2 and the cushion 3 can be completely placed inside the cavity 11, the sofa maintains a relatively neat shape during transportation, making it easy to move and store.

[0025] The sofa uses the base 1 as its outer shell and transforms it into outer packaging. It utilizes its own structure to protect the internal components, eliminating the need for a large amount of additional packaging materials, thus reducing packaging costs and waste generated from packaging materials, which aligns with environmental protection principles.

[0026] By storing the backrest 2 and seat cushions within the base 1, the packaging volume is significantly reduced (to only one-third of the finished product). During transportation, the same transport vehicle can carry more sofas, improving transportation efficiency and reducing unit transportation costs. Furthermore, since the backrest 2 and cushions 3 are stored within the cavity 11 of the base 1, they receive better protection, reducing damage caused by collisions, friction, and other factors.

[0027] Multiple sofa modules can be combined to form sofa sets suitable for multiple users. Users can flexibly adjust the sofa combination according to their needs and space, improving the product's practicality and applicability.

[0028] In some practical applications, the base 1 is made of recycled plastic in a single piece. The outer fabric cover of the backrest 2 or cushion 3 is made of a blend of fibers from recycled plastic waste and natural cotton and linen. This aligns with the design concept of sustainable development.

[0029] In some practical applications, several foot pads 4 are also installed at the lower end of the base 1, which are used to support the overall structure of the sofa.

[0030] In some practical applications, based on any of the above embodiments, this embodiment is structurally designed for the detachable connection between the backrest 2 and the base 1: Refer to Figure 2 and Figure 4 As shown, the base 1 has at least one first hole 12 extending into the cavity 11, and the lower end of the backrest 2 has an insert 21 corresponding to the first hole 12. The insert 21 is inserted into the first hole 12, and the backrest 2 abuts against the base 1. By laterally moving the insert 21, at least a portion of the structure on the base 1 is embedded in the slot 22 on the insert 21, thereby achieving axial positioning of the backrest 2 relative to the base 1. Specifically, the first hole 12 is configured as a square hole adapted to the width of the insert 21.

[0031] In the sofa configuration, the connection between the backrest 2 and the base 1 is achieved through the insert 21 and the first hole 12. First, align the insert 21 at the lower end of the backrest 2 with the first hole 12 on the base 1 that extends into the cavity 11. Then, insert the insert 21 into the first hole 12, so that the backrest 2 rests against the base 1. Next, move the insert 21 laterally, i.e., towards the rear of the sofa. At this point, at least a portion of the structure on the base 1 will be embedded in the slot 22 on the insert 21, thus providing axial restraint and ensuring that the backrest 2 will not easily detach axially from the base 1 during use, guaranteeing the stability of the overall sofa structure. Whether installing the backrest 2 onto the base 1 or removing it from the base 1, the entire process only requires inserting the insert 21, moving it laterally, and reversing the operation. The steps are simple and easy to understand, requiring no complex tools or professional skills, making it convenient for users or manufacturers to assemble and disassemble the sofa.

[0032] In some practical applications, based on any of the above embodiments, this embodiment focuses on the structural design of how the soft pad 3 is stably laid on the base 1: Refer to Figure 2 and Figure 5 As shown, the base 1 has at least one second hole 13 extending into the cavity 11, and a slot 131 communicating with the second hole 13 is located beside it. The cushion 3 is connected to an elastic cord 31 corresponding to each of the second holes 13, and a retaining ball 32 located at the end of each elastic cord 31. The retaining ball 32 passes through the second hole 13 into the cavity 11, allowing the elastic cord 31 to enter the slot 131, so that the retaining ball 32 abuts against the top wall of the cavity 11. In practical applications, four sets of elastic cords 31 are configured and connected to the four corners of the cushion 3, and four corresponding second holes 13 are also configured on the base 1, thereby improving the stability of the cushion 3.

[0033] In the sofa configuration, when the cushion 3 needs to be placed on the base 1, first align the retaining ball 32 at the end of the elastic cord 31 connected to the cushion 3 with the second hole 13 on the base 1. Because the retaining ball 32 has a certain degree of elasticity and deformability, it can pass through the second hole 13 and enter the cavity 11 of the base 1. As the retaining ball 32 passes through the second hole 13, the elastic cord 31 moves along with it and enters the slot 131 communicating with the second hole 13. Once the retaining ball 32 is fully inside the cavity 11, because the elastic cord 31 is secured in the slot 131, the retaining ball 32 will press against the top wall of the cavity 11. At this time, the elastic cord 31 is in a stretched state, using its elastic tension to firmly fix the cushion 3 to the base 1, ensuring that the cushion 3 will not easily slide or shift during use. In the transport state, simply pull the soft pad 3 to overcome the tension of the elastic rope 31, causing the locking ball 32 to detach from the top wall inside the cavity 11, and then pull the locking ball 32 out from the second hole 13 to separate the soft pad 3 from the base 1, making it convenient to roll or fold the soft pad 3 into the cavity 11 of the base 1.

[0034] In this embodiment, the cushion 3 is firmly fixed to the base 1 by the elastic tension of the elastic cord 31 and the retaining ball 32. This fixing method can effectively prevent the cushion 3 from sliding or wrinkling during use, keeping the cushion 3 flat and beautiful, and also improving the user's comfort when sitting on the sofa.

[0035] The process of installing and removing the cushion 3 is simple: the user only needs to align the retaining ball 32 with the second hole 13 and insert or pull it out. No tools are required, making it convenient and quick. This greatly facilitates the user's daily cleaning or replacement of the cushion 3.

[0036] In some practical applications, the backrest 2 rests against at least one elastic cord 31 on the cushion 3 to achieve lateral limiting of the backrest. That is, after the backrest and the cushion are installed in place, the backrest just rests against the elastic cord to achieve lateral compression limiting and ensure the stability of the insert 21 on the backrest 2 after it is inserted into the first hole 12.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
