Description

Technical Field

[0001] This utility model relates to the technical field of sofas, and more specifically, to a sponge sofa bed with a backrest. Background Technology

[0002] A sofa bed is a type of bed that can be used as both a sofa and a bed, and it comes in a variety of styles.

[0003] However, existing sofa bed structures typically involve designing a foldable frame, on which seat cushions or sleeping mats are then installed. During use, the foldable frame is used to switch between sofa and bed modes. As such, the structure of existing sofa beds is relatively complex, and the switching process is quite laborious. Furthermore, because existing sofa beds have many mechanical components, they are usually transported in disassembled form rather than compressed as a whole, making assembly rather troublesome. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a sponge sofa bed with a backrest to solve the problems in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sponge sofa bed with a backrest, including a base module, a foldable middle module connected to one side of the base module, a backrest module provided on the side of the middle module away from the base module, and a backrest assembly detachably connected to the side of the base module away from the middle module, so that the backrest module is supported by the backrest assembly when the base module, middle module and backrest module are folded.

[0006] This structure allows the base module and the middle module to fold together, making it easy to switch between sofa and bed modes. In sofa mode, the support component can support the backrest module, preventing it from collapsing due to lack of support, making it more convenient to use.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] As a further improvement of this utility model, the backrest module is placed on the middle module, and the side of the backrest module is supported by a support assembly.

[0009] This structure allows the backrest module 3 to be removed and used separately, making the use process more flexible.

[0010] As a further improvement of this utility model, the support assembly includes two pressure rods and two vertical rods. The two pressure rods are connected by a lower horizontal rod, and the two vertical rods are connected by an upper horizontal rod. The pressure rods and vertical rods are connected to each other to form an L-shape. The base module is pressed onto the pressure rods, and the base module is detachably connected to the lower horizontal rod and the upper horizontal rod respectively.

[0011] This structure allows users to press down on the support rod after sitting on the base module, enabling the vertical rod to provide more stable support for the backrest module. Since the support components can be detached from the base module, it is convenient for assembly and also allows for easy compression of the foam sofa bed during transportation, making it convenient for transport.

[0012] As a further improvement of this utility model, it also includes an outer cover, which has a first cavity, a second cavity and a third cavity respectively. The base module is located in the first cavity, the middle module is located in the second cavity, and the backrest module is located in the third cavity. The first cavity, the second cavity and the third cavity have a folding structure relative to each other. The outer cover and the support assembly are detachably connected.

[0013] This structure allows the base module, middle module, and backrest module to be covered and wrapped by the cover, while also making it easy to fold and switch between the three modules. It also allows for easy connection and use with the support components via the cover.

[0014] As a further improvement of this utility model, the base module includes a first sponge layer, the middle module includes a second sponge layer, and the backrest module includes a third sponge layer. The first sponge layer is disposed in a first cavity, the second sponge layer is disposed in a second cavity, and the third sponge layer is disposed in a third cavity. The upper ends of the first cavity and the second cavity are connected to form a first non-connected area between the first cavity and the second cavity, and the upper ends of the second cavity and the third cavity are connected to form a second non-connected area between the second cavity and the third cavity.

[0015] This structure allows each cavity to fold together, resulting in a more compact overall structure and easier use.

[0016] As a further improvement of this utility model, a first inclined surface is provided on the side of the second non-connected area near the second cavity, and a corresponding second inclined surface is provided on the other side.

[0017] This structure allows the two inclined surfaces of the middle module and the backrest module to combine when switching to sofa mode, making the middle module and the backrest module perpendicular. With the support component behind the backrest module providing support, the backrest module becomes more stable.

[0018] As a further improvement of this utility model, a first retaining ring is installed on the lower crossbar, a second retaining ring is installed on the upper crossbar, a first buckle connected to the first retaining ring is provided on the lower side of the outer sleeve near the lower crossbar, and a second buckle connected to the second retaining ring is provided on the upper side of the outer sleeve near the upper crossbar.

[0019] This structure makes it easier to assemble and disassemble the support components, and also prevents the support components from detaching during use.

[0020] As a further improvement of this utility model, two L-shaped fixing brackets are installed on the sides of both pressure rods, and armrest boxes mounted on the L-shaped fixing brackets are provided on both sides of the base module. The L-shaped fixing brackets are provided with mounting holes, and the mounting holes are connected to the armrest boxes by bolts.

[0021] This structure allows for fixed installation of the armrest box, and it is also easy to assemble and disassemble.

[0022] As a further improvement of this utility model, handrail supports are installed on the sides of both pressure rods, and sponge handrails mounted on the handrail supports are provided on both sides of the base module.

[0023] This structure allows the foam armrest to be held between the base module and the L-shaped fixing bracket, making it easy to assemble and disassemble.

[0024] The advantages of this utility model are: the overall structure is simple, it can be easily switched between sofa and bed modes, the switching process is relatively effortless, it has high applicability, a variety of usage styles, the backrest support is good in sofa mode, preventing the backrest from collapsing, and it is also convenient to disassemble the backrest components for compression and overall transportation.

Detailed Implementation

[0035] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] Combination Figures 1 to 5 The illustrated foam sofa bed with a backrest includes a base module 1, a foldable middle module 2 connected to one side of the base module 1, a backrest module 3 located on the side of the middle module 2 away from the base module 1, and a detachable support assembly 4 connected to the side of the base module 1 away from the middle module 2. This allows the base module 1 and middle module 2 to be folded in the same state, with the backrest module 3 supported by the support assembly 4. In this embodiment, the base module 1, middle module 2, and backrest module 3 can be folded together to facilitate switching between sofa and bed modes. Furthermore, the support assembly 4 provides support for the backrest module 3 in sofa mode, preventing it from collapsing due to lack of support, making it more convenient to use.

[0038] In this embodiment, the support assembly 4 includes two pressure rods 5 and two vertical rods 6. The two pressure rods 5 are connected by a lower horizontal rod 7, and the two vertical rods 6 are connected by an upper horizontal rod 9. The pressure rods 5 and vertical rods 6 are interconnected to form an L-shape. The base module 1 is pressed onto the pressure rods 5 and is detachably connected to both the lower horizontal rod 7 and the upper horizontal rod 9. This allows the user to press down on the pressure rods 5 after sitting on the base module 1, providing more stable support for the backrest module 3. Since the support assembly 4 can be detached from the base module 1, it facilitates assembly and allows for easy compression of the foam sofa bed during transportation, making it convenient for transport.

[0039] The foam sofa bed in this embodiment also includes an outer cover 11, which contains a first cavity, a second cavity, and a third cavity. The base module 1 is located in the first cavity, the middle module 2 is located in the second cavity, and the backrest module 3 is located in the third cavity. The first cavity, the second cavity, and the third cavity have a folding structure. The outer cover 11 is detachably connected to the support assembly 4. This allows the base module 1, the middle module 2, and the backrest module 3 to be covered and wrapped by the outer cover 11, while also facilitating the folding and switching of the three modules. It also allows for easy connection and use between the outer cover 11 and the support assembly 4.

[0040] In this embodiment, the base module 1 includes a first sponge layer 12, the middle module 2 includes a second sponge layer 13, and the backrest module 3 includes a third sponge layer 14. The first sponge layer 12 is disposed in the first cavity, the second sponge layer 13 is disposed in the second cavity, and the third sponge layer 14 is disposed in the third cavity. The upper ends of the first cavity and the second cavity are connected to form a first non-connected area 17 between them, and the upper ends of the second cavity and the third cavity are connected to form a second non-connected area between them. This allows each cavity to fold over, resulting in a more compact overall structure and greater ease of use.

[0041] It is worth noting that in this embodiment, the second non-connected area has a first inclined surface 18 on one side near the second cavity, and a corresponding second inclined surface 19 on the other side. This allows the two inclined surfaces of the middle module 2 and the backrest module 3 to combine when switched to sofa mode, making the middle module 2 and the backrest module 3 perpendicular. With the support component 4 providing support behind the backrest module 3, the backrest module 3 becomes more stable.

[0042] In this embodiment, a first retaining ring 8 is installed on the lower crossbar 7, and a second retaining ring 10 is installed on the upper crossbar 9. A first buckle 15, connected to the first retaining ring 8, is provided on the lower side of the outer sleeve 11 near the lower crossbar 7, and a second buckle 16, connected to the second retaining ring 10, is provided on the upper side of the outer sleeve 11 near the upper crossbar 9. This makes it easier to assemble and disassemble the support assembly 4, and also prevents the support assembly 4 from detaching during use.

[0043] The overall structure of the foam sofa bed in this embodiment is simpler than that of a traditional sofa. The entire main body is formed by a foam cover 11, and each part can be easily switched between sofa and bed modes. The switching process is relatively effortless, highly applicable, and offers a variety of styles. In sofa mode, the backrest provides good support and prevents the backrest from collapsing. Furthermore, the entire main body can be easily disassembled, and the support components 4 can be compressed and packaged for overall transportation.

[0044] Example 2

[0045] See Figure 6 and Figure 7 As shown, the difference between this embodiment and embodiment one is that two L-shaped fixing brackets 20 are installed on the sides of both pressure rods 5. Armrest boxes 21 mounted on the L-shaped fixing brackets 20 are provided on both sides of the base module 1. The L-shaped fixing brackets 20 have mounting holes, which are connected to the armrest boxes 21 by bolts. The armrest boxes 21 are made of wood, which allows the armrest boxes 21 to be fixedly installed and easy to disassemble and assemble. Moreover, the armrest boxes 21 can be disassembled before transportation so that the base module 1, the middle module 2, and the backrest module 3 can be compressed and packaged.

[0046] Example 3

[0047] See Figure 8 and Figure 9 The difference between this embodiment and the first embodiment is that the sides of both pressure rods 5 are equipped with handrail support frames 22, and the sides of the base module 1 are provided with sponge handrails 23 mounted on the handrail support frames 22; this allows the sponge handrails 23 to be clamped between the base module 1 and the L-shaped fixing frame 20 for use, making disassembly and assembly more convenient.

[0048] Example 4

[0049] like Figure 1The illustrated foam sofa bed with a backrest includes a base module 1. A foldable middle module 2 is connected to one side of the base module 1. A backrest module 3, made of foam, is located on the side of the middle module 2 away from the base module 1. The backrest module 3 is placed on the middle module 2. A support assembly 4 is detachably connected to the side of the base module 1 away from the middle module 2. This allows the backrest module 3 to be supported on its back or side by the support assembly 4 when the base module 1 and the middle module 2 are folded. This structure allows the backrest module 3 to be removed and used independently, making it more flexible in use. In this embodiment, the base module 1 and the middle module 2 can be folded together to switch between sofa and bed modes. Moreover, the support assembly 4 provides support for the backrest module 3 in sofa mode, preventing it from collapsing due to lack of back support, making it more convenient to use.

[0050] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
