Technical Field
[0001] This utility model belongs to the field of sofa technology, and in particular relates to a portable compression sofa. Background Technology
[0002] A sofa is a multi-seat chair with cushions. It has a backrest with springs or thick foam, and armrests on both sides; it is a type of upholstered furniture.
[0003] For example, patent CN220212430U discloses a compressible sofa, comprising a sofa body supported by at least compressible springs. The sofa body includes a base, backrest, and armrests, all of which are supported by compressible springs, and all springs are parallel to each other, allowing the sofa body to be completely compressed. This invention provides a fully compressible sofa, enabling it to be fully compressed and packaged for transport, thus facilitating sofa transportation. Furthermore, the ability to compress the sofa as a whole means that when the compressed sofa is transported to its intended location, it can be easily reassembled by simply unpacking, eliminating the need for reinstallation and facilitating quick use.
[0004] The current sofa requires users to compress it before binding it in use; however, compressing and binding the sofa is quite strenuous. Therefore, we propose a portable compressible sofa. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned technical problems by providing a portable compression sofa that avoids the difficulty of compression and binding.
[0006] In view of this, the present invention provides a portable compression sofa, including a main sofa, a side sofa attached to the outer wall of the main sofa, an armrest provided at the top edge of the main sofa, an inner Velcro closure at the connection between the inner wall of the armrest and the main sofa, an outer Velcro closure at the connection between the outer wall of the armrest and the main sofa, a base plate fixedly connected to the inner wall of the main sofa, a threaded seat fixedly connected to the outer wall of the base plate, a bolt threadedly connected to the inner wall of the threaded seat, a middle plate sleeved on the outer wall of the bolt, a rib plate fixedly connected to the outer wall of the middle plate, a rotating seat fitted at the top of the bolt, a top plate fixedly connected to the outer wall of the rotating seat, a washer provided at the top of the top plate, a pressure frame fitted to the inner wall of the top plate, a limiting plate slidably connected to the outer wall of the rib plate fixedly connected to the outer wall of the pressure frame, a lower spring assembly provided at the connection between the base plate and the middle plate, and an upper spring assembly provided at the connection between the middle plate and the top plate.
[0007] Based on the above structure, the rotation of the bolt drives the top plate on the outer wall of the rotating seat to move downward through the threaded seat, so that the top plate drives the limiting plate on the outer wall of the pressure frame to slide vertically along the outer wall of the rib, which facilitates the stability of the top plate movement. The movement of the top plate compresses the lower spring assembly and the upper spring assembly through the middle plate, thereby reducing the overall volume of the sofa and making it easier to move the sofa.
[0008] Preferably, the main sofa and the side sofa have the same internal structure, which facilitates the compression and transportation of the main sofa and the side sofa in this embodiment.
[0009] Preferably, the inner Velcro has an "L" shaped cross-section, and the outer Velcro has a long strip shape. In this embodiment, by setting the inner Velcro with an "L" shaped cross-section and the outer Velcro with a long strip shape, it is beneficial to improve the stability of the connection between the sofa and the armrest, and prevent the armrest from shifting or even slipping off.
[0010] Preferably, both the rib and the pressure frame are cross-shaped and parallel to each other. In this embodiment, by setting the cross-shaped rib, the deformation of the intermediate plate under pressure is avoided. By setting the cross-shaped pressure frame, the stability of the top plate compression is improved and the top plate is prevented from deflecting.
[0011] Preferably, the outer wall of the rib is provided with a sliding groove that fits into the limiting plate. In this embodiment, the top plate drives the limiting plate of the outer wall of the pressure frame to slide vertically along the outer wall of the rib, which helps to improve the stability of the top plate movement.
[0012] Preferably, the top plate forms a compression structure with the bottom plate through a pressure frame, and the top plate and bottom plate are parallel. In this embodiment, the movement of the top plate compresses the lower spring group and the upper spring group through the middle plate, thereby reducing the overall volume of the sofa and making it easier to move the sofa.
[0013] Preferably, there are four sets of lower spring groups and upper spring groups, which are symmetrical about the rib plate. In this embodiment, by setting four sets of lower spring groups and upper spring groups, deformation of the sofa after long-term use can be avoided.
[0014] The beneficial effects of this utility model are:
[0015] 1. This portable compression sofa features inner and outer Velcro straps, allowing users to securely fasten the armrests to the top edges of the main and side sofas, preventing them from shifting or slipping off.
[0016] 2. This portable compression sofa, by setting up a pressure frame and ribs, the rotation of the bolt drives the top plate on the outer wall of the rotating seat to move downward through the threaded seat, so that the top plate drives the limiting plate on the outer wall of the pressure frame to slide vertically along the outer wall of the rib, which facilitates the stability of the top plate movement. The movement of the top plate compresses the lower spring assembly and the upper spring assembly through the middle plate, thereby reducing the overall volume of the sofa and making it easier to move the sofa.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0025] This application discloses a portable compressible sofa, including a main sofa 1, side sofas 2 attached to the outer wall of the main sofa 1, armrests 3 provided at the top edge of the main sofa 1, inner Velcro 4 provided at the connection between the inner wall of the armrests 3 and the main sofa 1, and outer Velcro 5 provided at the connection between the outer wall of the armrests 3 and the main sofa 1, a base plate 6 fixedly connected to the inner wall of the main sofa 1, a threaded seat 7 fixedly connected to the outer wall of the base plate 6, a bolt 8 threadedly connected to the inner wall of the threaded seat 7, and a sleeve on the outer wall of the bolt 8. There is an intermediate plate 9, and a rib plate 10 is fixedly connected to the outer wall of the intermediate plate 9. A rotating seat 11 is fitted into the top of the bolt 8. A top plate 12 is fixedly connected to the outer wall of the rotating seat 11. A gasket 13 is provided at the top of the top plate 12. A pressure frame 14 is fitted into the inner wall of the top plate 12. A limiting plate 15 that is slidably connected to the outer wall of the rib plate 10 is fixedly connected to the outer wall of the pressure frame 14. A lower spring assembly 16 is provided at the connection between the bottom plate 6 and the intermediate plate 9. An upper spring assembly 17 is provided at the connection between the top plate 12 and the intermediate plate 9.
[0026] Based on the above structure, the rotation of bolt 8 drives the top plate 12 on the outer wall of rotating seat 11 to move downward through threaded seat 7, so that the top plate 12 drives the limiting plate 15 on the outer wall of pressure frame 14 to slide vertically along the outer wall of rib plate 10, which facilitates the stability of the movement of top plate 12. The movement of top plate 12 compresses the lower spring group 16 and upper spring group 17 through middle plate 9, thereby reducing the overall volume of sofa and facilitating the movement of sofa.
[0027] In one embodiment, the main sofa 1 and the side sofa 2 have the same internal structure.
[0028] In this embodiment, it is convenient to compress and move the main sofa 1 and the side sofa 2.
[0029] In one embodiment, the inner hook and loop fastener 4 has an "L" shaped cross-section, and the outer hook and loop fastener 5 has a long strip shape.
[0030] In this embodiment, by setting an inner Velcro 4 with an "L"-shaped cross-section and an outer Velcro 5 in the shape of a long strip, it is beneficial to improve the stability of the connection between the sofa and the armrest 3 and prevent the armrest 3 from shifting or even slipping off.
[0031] In one embodiment, both the rib plate 10 and the pressure frame 14 are cross-shaped, and the rib plate 10 and the pressure frame 14 are parallel.
[0032] In this embodiment, by setting a cross-shaped rib 10, the deformation of the middle plate 9 under pressure is avoided. By setting a cross-shaped pressure frame 14, the stability of the top plate 12 under compression is improved, and the top plate 12 is prevented from deflecting.
[0033] In one embodiment, the outer wall of the rib plate 10 is provided with a groove that fits into the limiting plate 15.
[0034] In this embodiment, the top plate 12 drives the limiting plate 15 on the outer wall of the pressure frame 14 to slide vertically along the outer wall of the rib plate 10, which facilitates the improvement of the stability of the movement of the top plate 12.
[0035] In one embodiment, the top plate 12 forms a compression structure with the bottom plate 6 via the pressure frame 14, and the top plate 12 and the bottom plate 6 are parallel.
[0036] In this embodiment, the movement of the top plate 12 compresses the lower spring assembly 16 and the upper spring assembly 17 through the middle plate 9, thereby reducing the overall volume of the sofa and making it easier to move.
[0037] In one embodiment, four sets of lower spring assemblies 16 and upper spring assemblies 17 are provided, and the four sets of lower spring assemblies 16 and upper spring assemblies 17 are symmetrical about the rib plate 10.
[0038] In this embodiment, by setting four sets of lower spring groups 16 and upper spring groups 17, deformation of the sofa after long-term use is prevented.
[0039] In this embodiment, when using the portable compression sofa, the user first uses the inner Velcro 4 and the outer Velcro 5 to securely fix the armrests 3 to the top edges of the main sofa 1 and the side sofa 2, preventing the armrests 3 from shifting or even slipping off.
[0040] Next, the main sofa 1 and the side sofa 2 are compressed. The user turns the bolt 8. The rotation of the bolt 8 drives the top plate 12 on the outer wall of the rotating seat 11 to move downward through the threaded seat 7. This causes the top plate 12 to drive the limiting plate 15 on the outer wall of the pressure frame 14 to slide vertically along the outer wall of the rib plate 10, which improves the stability of the movement of the top plate 12. The movement of the top plate 12 compresses the lower spring assembly 16 and the upper spring assembly 17 through the middle plate 9, thereby reducing the overall volume of the sofa and making it easier to move the sofa.
