Description

Technical Field

[0001] This utility model belongs to the field of air cushion sofa technology, specifically relating to an environmentally friendly, multi-purpose, modular air cushion sofa. Background Technology

[0002] Sofas are one of the most commonly used pieces of furniture, but most sofas are made of wood. The production of wooden sofas requires the felling of a large number of trees, and excessive felling of trees can cause various environmental problems such as soil erosion, which is detrimental to environmental protection. In order to overcome this difficulty, air cushion sofas with inflatable designs have become popular due to their environmental friendliness and portability. Air cushions can provide a good sitting experience and support, and are widely used in various scenarios such as homes, offices, and lounges.

[0003] Currently, existing air-cushioned sofas are relatively lightweight. When no one is on top of them and they are positioned by their own weight, they are easily shifted due to external factors. Sliding indoors can easily damage the surface of the air-cushioned sofa, and in severe cases, it can even lead to air leakage. When used outdoors, they are easily affected by the weather and can be blown away by strong winds.

[0004] Therefore, given the problem that existing air-cushioned sofas are lightweight and prone to shifting due to external forces when not in use after inflation, an environmentally friendly, multi-purpose, modular air-cushioned sofa with a support frame can be designed. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of an environmentally friendly, multi-purpose, modular air cushion sofa, including an inflatable sofa body 1 and a positioning pin 2. The inflatable sofa body 1 has a built-in air pump, and an inflation / deflation port 4 connected to the air pump is located on one side of the inflatable sofa body 1. A support frame 5 is located at the bottom of the inflatable sofa body 1, and a folding frame 6 is located on one side of the support frame 5, opposite to the support frame 5. The folding frame 6 is movably connected to the support frame 5. A first storage slot 7 is located at the bottom of the support frame 5 and the folding frame 6, and the positioning pin 2 is movably connected within the first storage slot 7. By installing the inflatable sofa body 1 onto the support frame 5 and the folding frame 6, the support frame 5 and the folding frame... 6. Support and protection are formed at the bottom of the inflatable sofa body 1. Rotate the positioning nail 2 in the first storage slot 7 to nail it into the grass for outdoor fixation. The inflatable sofa body 1 draws air from the outside into the inflatable sofa body 1 through the inflation and deflation port 4 through the built-in air pump to achieve support. After use, the inflation and deflation port 4 is discharged to facilitate folding and storage. The positioning nail 2 is fixedly connected to the first rotating shaft 8 on the left and right sides. The first rotating shaft 8 is rotatably connected in the first storage slot 7. The positioning nail 2 can be rotated through the first rotating shaft 8. This design allows the positioning nail 2 to be stored, which is convenient for both outdoor and indoor use scenarios.

[0025] Please see Figures 3-6In this embodiment, both the support frame 5 and the folding frame 6 have front-to-back opposing second storage slots 9 at their top ends. A support column 10 is movably connected within the second storage slot 9. The bottom of the air cushion sofa has a support slot 11 that matches the support column 10. The support column 10 can rotate within the second storage slot 9 to achieve folding and storage, which helps users reduce the space occupied by the support frame 5 and the folding frame 6 and improves portability. The support column 10, in conjunction with the support slot 11, can fix the fully inflated air cushion sofa body 1 above the support frame 5 and the folding frame 6. The front and rear ends of the support column 10 are fixedly connected to second rotating shafts 12, which are rotatably connected within the second storage slot 9. The support column 10 can rotate within the second storage slot 9 through the second rotating shafts 12. The support frame 5 and the folding frame 6 have front-to-back opposing rotating slots 13 on opposite sides. A connector 14 is movably connected within the rotating slot 13, which connects the support frame 5 and the folding frame 6. The rotating groove 13 is fixedly connected to a No. 3 rotating shaft 15. The two No. 3 rotating shafts 15 are respectively rotatably connected to the two ends of the connector 14. Through the No. 3 rotating shafts 15, the connector 14 and the folding frame 6 can rotate and change their angles, so that the folding frame 6 can be tightly attached to the bottom end of the support frame 5. This enables the support frame 5 and the folding frame 6 to be folded and stored, reducing the transportation space they occupy and improving their portability. A fixed suction cup 16 is set between the two support columns 10 and fixedly installed on the top of the support frame 5 and the folding frame 6. The fixed suction cup 16 is attached to the bottom end of the inflatable sofa body 1. In order to prevent the inflatable sofa body 1 from falling off the support column 10, the air is discharged through the fixed suction cup 16, and the negative pressure generated uses the external atmospheric pressure to press the suction cup tightly to the bottom end of the sofa. The support column 10 and the support groove 11 at this time play a positioning role, which can prevent the installation of the inflatable sofa body 1 from being misaligned with the support frame 5 and the folding frame 6.

[0026] During installation, the user first transports the folding frame 6 (rotated below the support frame 5) along with the inflatable sofa body 1 (folded and stored without inflation) to the desired location. If the location is indoors, forcefully rotate the folding frame 6, causing the third pivot 15 to rotate the folding frame 6 along the connector 14. Then, forcefully rotate the support frame 5, causing the third pivot 15 to rotate the support frame 5 along the connector, ensuring that the support frame 5 and the folding frame 6 are on the same horizontal plane. Finally, rotate the support column 10, causing the second pivot 12 to rotate the support column 10 along the connector. Rotate the inflatable sofa body 1 in the storage slot 9 to form a vertical state, unfold the folded inflatable sofa body 1, start the built-in air pump, the air pump draws external air into the inflatable sofa body 1 through the air inflation port 4, supporting the inflatable sofa body 1. After inflation is complete, align the support slot 11 with the support column 10 and fit it on the outside of the support column 10. When moving downward, the bottom of the inflatable sofa body 1 squeezes the fixed suction cup 16, squeezing out the air in the suction cup. Through the pressure difference inside and outside the fixed suction cup 16, the inflatable sofa body 1 is fixed on the fixed suction cup 16.

[0027] If used on an outdoor grassy area, after rotating the support column 10, rotate the positioning pin 2. The first rotating shaft 8 drives the positioning pin 2 to rotate in the first storage slot 7, so that it is perpendicular to the support frame 5 and the folding frame 6. Insert it into the grass below to fix it, and then fix the inflatable sofa body 1 above the support frame 5.

[0028] After use, pull out the inflatable sofa body 1 upwards, use the air pump to expel the internal air from the air inlet 4, then fold it up, rotate the support column 10 to fold it into the second storage slot 9, rotate the positioning pin 2 to fold it into the first storage slot 7, and then rotate the support frame 5 and the folding frame 6 to make the folding frame 6 fit tightly against the bottom of the support frame 5.

[0029] Through the above steps, a support frame 5 and a folding frame 6 are added to the bottom of the inflatable sofa. The bottom of the support frame 5 and the folding frame 6 are movably connected to the positioning nail 2. When used indoors, the support frame 5 can form a barrier between the bottom of the inflatable sofa body 1 and the ground, protecting the bottom of the sofa body and preventing the bottom of the sofa from being scratched due to dragging. When used outdoors, the positioning nail 2 can be rotated to keep it in a vertical state and nailed into the grass to form a fixed position. This solves the problem that existing air cushion sofas are relatively light and are prone to shifting due to external forces when they are not in use after being inflated.
