[0025] Embodiment 1:

[0026] In this embodiment, a multifunctional geometric cushion-type sofa, as Figures 1 to 3 shown, includes a support portion 1 and a folding portion 2. Specifically, the above support portion 1 is used to support the user's waist, and the above folding portion 2 is used for the user to lie, recline, and sit. The above folding portion 2 is a hollow soft cushion. One end of the above folding portion 2 is connected to the above support portion 1. The above folding portion 2 is provided with a plurality of folding lines 3. The above folding lines 3 divide the above folding portion 2 into a plurality of filling plates 4. Flexible fillers are provided in the above filling plates 4. The plurality of above filling plates 4 can be folded up through the above folding lines 3 to form a relatively thick cushion.

[0027] With this structure, when the folding part 2 is unfolded and the filling plate 4 is laid on the floor, the user can lie semi-reclined or on the side, and when folded, the user can sit on the folding part 2. In both usage scenarios, the support part 1 can conform to the curve of the human waist, providing effective support to the user's back position, ensuring that the user can feel comfortable in various postures. The foldable structure makes the volume and weight of the cushion sofa smaller, more suitable for small-sized houses, and convenient for storage and carrying.

[0028] As a specific implementation manner of this embodiment, as Figure 1 and Figure 2 shown, the number of the above-mentioned filling plates 4 is three, the shape of the above-mentioned filling plates 4 is an equilateral triangle, and two adjacent above-mentioned filling plates 4 are connected by the above-mentioned folding line 3. The three above-mentioned filling plates 4 are combined to form the above-mentioned folding part 2 in an isosceles trapezoid shape. The three above-mentioned filling plates 4 in an equilateral triangle can completely overlap after folding, and the length of the above-mentioned folding part 2 formed after unfolding is sufficient to support the body postures of the user in different lying and reclining postures. Among them, a zipper can be provided at the edge of the above-mentioned filling plate 4 for placing the above-mentioned flexible filler into the above-mentioned filling plate 4, or the zipper can not be provided, and the filling opening can be completely hidden by sewing. The above-mentioned flexible filler is preferably sheet cotton, and sheet cotton has the advantages of softness, comfort, moderate thickness, and no influence on folding. Other flexible materials such as sponge, latex, and down can also be filled.

[0029] In this embodiment, as Figures 1 to 3 shown, the number of the above-mentioned folding lines 3 is two. One end of the two above-mentioned folding lines 3 coincides with the midpoint of the long side of the above-mentioned folding part 2, and the other ends of the two above-mentioned folding lines 3 respectively coincide with the two ends of the short side of the above-mentioned folding part 2. The two above-mentioned filling plates 4 far from the above-mentioned support part 1 are folded in sequence so that they overlap on the above-mentioned filling plate 4 connected to the above-mentioned support part 1, enabling the user to sit on it in a sitting position and lean the back against the above-mentioned support part 1.

[0030] In this embodiment, as Figure 4 shown, anti-slip protrusions 5 are provided on the bottom sides of the above-mentioned filling plates 4. The above-mentioned anti-slip protrusions 5 increase the friction coefficient of the bottom side of the above-mentioned folding part 2. When the above-mentioned folding part 2 is laid on the floor, the above-mentioned anti-slip protrusions 5 prevent the above-mentioned folding part 2 from sliding easily, thus providing a good user experience to the user. The above-mentioned anti-slip protrusions 5 can be set as a plurality of evenly distributed convex points, or can be set as convex strips arranged in parallel or staggered, which can achieve the same effect of stabilizing the above-mentioned folding part 2.

[0031] According to a preferred implementation manner, as Figures 2 to 4As shown, the shape of the support portion 1 is a regular tetrahedron, the size and shape of the three side walls of the support portion 1 are the same as the filling plate 4, a waist edge of the folding portion 2 is fixedly connected to a bottom edge of the support portion 1, and the three filling plates 4 can be sequentially covered on the three side walls of the support portion 1. In this way, when the sofa is not in use, the folding portion 2 can be completely attached to the support portion 1, and the three filling plates 4 correspond to the three side walls of the support portion 1 one by one, thereby completely wrapping the support portion 1. At this time, the bottom side of the folding portion 2 is exposed to the outside, isolating dust, keeping the inside of the support portion 1 and the folding portion 2 clean and hygienic, and also reducing the space occupied by the sofa, making it more convenient to store.

[0032] In this embodiment, the support part 1 is filled with foam particles and crushed sponge. The foam particles can deform themselves according to the pressure they are subjected to, so as to fit the physiological curve of the user's waist and back, improve the support effect and comfort. At the same time, the crushed sponge can provide necessary support for the support part 1 to ensure the stability and safety of the sofa when in use. The degradation cycle of the foam particles is relatively long. Compared with the full foam particle filling of ordinary sofas, the filling method of foam particles and crushed sponge uses less foam particles and is more environmentally friendly. As an optimization, a zipper is provided on the bottom side of the support part 1 or on the side away from the folding part 2, which is used to fill the foam particles and crushed sponge into the support part 1. The zipper may also be not provided, and the filling port may be completely hidden by sewing. Among them, the support part 1 may also be filled with PP cotton or pearl cotton or one-piece cut sponge and other fillers with similar physical properties.

[0033] As an optimization, Figures 1 to 4 As shown, buckles 6 are provided at both ends of one side edge of the support portion 1, and two buttons 7 corresponding to the positions of the buckles 6 are provided on one side of the folding portion 2. When the three filling panels 4 of the folding portion 2 cover the three side walls of the support portion 1, the two buttons 7 can be respectively nested in the two buckles 6, so as to fix the folding portion 2 on the support portion 1, which is convenient for storage and prevents the folding portion 2 from spreading out. The buckles 6 and buttons 7 can also be replaced with hidden buttons or magic sticky tape to achieve the same fixing effect.

[0034] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
