Description

Technical Field

[0001] This application relates to the field of sofa technology, and more particularly to an inflatable single sofa. Background Technology

[0002] Inflatable sofa modules are an innovative furniture design that uses air to change the shape and firmness of the sofa, adapting it to different usage scenarios and needs. This design is not only easy to carry and store but also offers high flexibility and comfort. However, existing inflatable sofas do not allow for easy adjustment of vertical support, which significantly reduces comfort during use. Utility Model Content

[0003] To address the problem of traditional inflatable sofas having difficulty adjusting the vertical support force, this utility model provides an inflatable single sofa, comprising: a sofa module and a seat cushion module;

[0004] The seat cushion module is an inflatable structure with an internal airbag;

[0005] The sofa module is an inflatable structure with an internal airbag, and the sofa module is ring-shaped with a pre-drilled seat cushion hole inside. The seat cushion hole matches the seat cushion module, and the seat cushion module can be embedded in the seat cushion hole of the sofa module.

[0006] In one possible implementation, the top of the sofa module has an arc-shaped transition structure recessed towards the seat cushion hole.

[0007] In one possible implementation, the bottom of the sofa module is flush with the floor or recessed towards the seat cushion hole.

[0008] In one possible implementation, the cushion hole is located at the center of the top of the sofa module.

[0009] In one possible implementation, the cushion module is spherical, and the diameter of the cushion module is smaller than the opening depth of the cushion hole.

[0010] In one possible implementation, a traction rope is also included, with its two ends connected to the bottom of the sofa module and the cushion module, respectively.

[0011] In one possible implementation, the cross-sectional diameter of the sofa module gradually increases and then gradually decreases along the opening direction of the seat cushion holes.

[0012] In one possible implementation, the thickness of the sofa module gradually increases along the horizontal direction.

[0013] In one possible implementation, the sidewalls of the sofa module are arc-shaped and recessed towards the top and bottom of the sofa module, respectively.

[0014] In one possible implementation, the sofa module and the cushion module are covered with fabric covers.

[0015] The beneficial effects of the inflatable single sofa according to this application embodiment are as follows: By embedding the seat cushion module into the seat cushion hole opened in the sofa module, and since both the seat cushion module and the sofa module are inflatable structures with internal airbags, the overall height and comfort can be adjusted by adjusting the inflation level of the seat cushion module. Furthermore, the seat cushion module independently supports the buttocks, while the sofa module provides lumbar and back support, forming an ergonomic curved surface, which significantly reduces ischial tuberosity pressure compared to traditional flat sofas.

[0028] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] like Figures 1-6 As shown, the inflatable single sofa 100 of this application embodiment includes: a sofa module 100 and a cushion module 200. The cushion module 200 is an inflatable structure with an internal airbag, and the sofa module 100 is an inflatable structure with an internal airbag. The sofa module 100 is annular and has a cushion hole 110 with reserved space inside. The cushion hole 110 matches the cushion module 200, and the cushion module 200 can be embedded in the cushion hole 110 of the sofa module 100.

[0030] In this specific embodiment, the seat cushion module 200 can be embedded in the seat cushion hole 110 opened on the sofa module 100. Both the seat cushion module 200 and the sofa module 100 are inflatable structures with internal airbags. The overall height and comfort can be adjusted by adjusting the inflation level of the seat cushion module 200. In addition, the seat cushion module 200 independently supports the buttocks, and the sofa module 100 provides lumbar and back support, forming an ergonomic curved surface. Compared with traditional flat sofas, the pressure on the ischial tuberosities is greatly reduced.

[0031] The sofa module 100 has a ring structure, which provides horizontal coverage. By adjusting the fullness of the support module, the overall vertical support force can be adjusted.

[0032] In one specific embodiment, the top and bottom of the sofa module 100 are both recessed with arc-shaped transition structures towards the seat cushion holes 110, forming a hyperboloid transition with a concave top and concave bottom. Thus, the arc shape at the top conforms to the curve of the buttocks, while the arc shape at the bottom reduces the impact of ground reaction force on the ischial tuberosities, reducing soreness after prolonged sitting. Furthermore, the arc transition enhances the edge strength of the module, preventing the right-angled edges from collapsing easily after inflation, while the concave top guides the user to sit naturally upright, preventing lateral slippage.

[0033] In this specific embodiment, the bottom of the sofa module 100 can also be a flat structure. A flat bottom allows the module to be stably supported on different surfaces such as carpets and tiles, avoiding the swaying caused by the uneven bottom of traditional inflatable sofas.

[0034] In one specific embodiment, the seat cushion hole 110 is located at the center of the top of the sofa module 100. When the user sits in the center position, the sofa module 100 is subjected to uniform force, avoiding structural fatigue caused by unilateral tilting. The central design of the seat cushion hole 110 provides a symmetrical structural basis for subsequent expansion functions.

[0035] In one specific embodiment, the seat cushion module 200 is spherical, and the diameter of the seat cushion module 200 is smaller than the opening depth of the seat cushion hole 110. The spherical seat cushion module 200 can be embedded in the seat cushion hole 110, or it can be removed for use as a footrest or leg rest. The opening depth of the seat cushion hole 110 is greater than the diameter of the seat cushion module 200, ensuring that the top of the seat cushion module 200 is lower than the upper surface of the sofa module 100 after it is embedded, preventing the seat cushion from popping out when getting up. The spherical airbag structure of the seat cushion module 200 is compressible in the vertical direction, improving overall comfort.

[0036] In one specific embodiment, a traction rope is also included, with its two ends connected to the bottom of the sofa module 100 and the seat cushion module 200, respectively. The traction rope is used to integrate the sofa module 100 and the seat cushion module 200 into a single unit. When the traction rope is straightened, its length is similar to that of a person's legs, facilitating the placement of feet or legs. Furthermore, the traction rope can prevent the spherical seat cushion module 200 from being lost.

[0037] In one specific embodiment, the cross-sectional diameter of the sofa module 100 gradually increases and then decreases along the opening direction of the seat cushion holes, forming a waist-drum shaped profile. The middle of the sofa module 100 is thickened to enhance lumbar support, while the top and bottom ends are narrowed to reduce material waste. Furthermore, the waist-drum shaped profile is more modern than a cylindrical shape, making it suitable for home aesthetic needs.

[0038] In one specific embodiment, the thickness of the sofa module 100 gradually increases along the horizontal direction, that is, a backrest is provided at the rear end of the sofa module 100 relative to the front end in the horizontal direction, which is convenient for reclining use.

[0039] In one specific embodiment, the sidewalls of the sofa module 100 are curved, with recesses at the top and bottom of the sofa module 100, respectively. The top recess conforms to the curve of the buttocks, and the bottom recess increases the contact area with the ground. Moreover, the curved surface can better disperse external forces than a flat surface, improving the module's puncture resistance and reducing the risk of breakage when a sharp object comes into contact with it.

[0040] In one specific embodiment, the sofa module 100 and the cushion module are covered with a fabric cover. The cover prevents the airbags from being scratched by sharp objects and extends the service life of the sofa module 100. The removable fabric cover is machine washable, and its water-repellent coating allows for quick wiping of stains, significantly improving hygiene.

[0041] In one specific embodiment, the support module can also be a hollow spherical structure that does not require inflation.

[0042] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
