[0034] like Figures 1 to 11 As shown, this embodiment discloses a folding hanging chair, including a folding assembly 1, two front seat tubes 2, and two backrest tube assemblies. The folding assembly 1 includes a first mounting base 11 and a plurality of second mounting bases 12. All the second mounting bases 12 are connected in sequence. The second mounting base 12 at the front end is hinged to the first mounting base 11. The front seat tube and the backrest tube assembly are each connected to a first mounting base or a second mounting base. A locking assembly for connecting the first mounting base to the second mounting base at the rear end is installed on the first mounting base.

[0035] The folding hanging chair has both a folded and an unfolded state;

[0036] When the folding hanging chair is in the folded state, the second mounting base 12 at the tail end is separated from the first mounting base 11;

[0037] When the folding chair is in the unfolded state, the second mounting seat 12 at the rear end is connected to the first mounting seat 11, and the two backrest tube assemblies and the two front seat tubes 2 together form a seating space.

[0038] The backrest tube assembly includes a backrest tube 3, a connecting tube 4, and a backrest liner tube 5. A spring with a ball bearing a 6 is installed in the connecting tube 4. The diameter of the connecting tube 4 is smaller than the diameters of the backrest tube 3 and the backrest liner tube 5. One end of the connecting tube 4 is fixedly connected to the backrest liner tube 5, and the other end is inserted into the backrest tube 3. The backrest tube 3 has a hole for receiving the ball bearing 6. The top surface of the backrest tube 3 contacts the bottom surface of the backrest liner tube 5, making the connecting tube 4 invisible. By pressing the ball bearing 6, the ball retracts, allowing the connecting tube 4 to be pulled out of the backrest tube 3, thereby removing the backrest liner tube 5 and reducing the storage volume of the folding hanging chair. In other embodiments, the backrest tube assembly is not limited to this. For example, the backrest liner tube 5 may have a constricted opening, on which a spring with a ball bearing 6 is installed. The constricted opening is inserted into the backrest tube 3, thus omitting the connecting tube 4.

[0039] In this embodiment, there are two backrest tubes 3 and two front seat tubes 2. Both the upper ends of the backrest tubes 3 and the front seat tubes 2 are equipped with seat fixing members 7. Each seat fixing member 7 includes a base 71, a positioning part 72, a baffle 73, and a stop part 74. The positioning part 72 extends downward from the center of the bottom surface of the base 71. The positioning part 72 is inserted into the upper end of the backrest tube 3 or the upper end of the front seat tube 2 and fixed to it (by means of rivets or screws). The base abuts against the upper end surface of the backrest tube 3 or the upper end surface of the front seat tube 2. The stop part 74 includes a cylindrical vertical column 741 and a horizontal part 742 extending horizontally from one side of the upper end of the column 741. The baffle 73 extends upward from the top surface of the base 71 and is located on one side of the column 741 of the stop part 74. The horizontal part 742 extends above the baffle 73. The seat (i.e., chair fabric) of the folding hanging chair has four pull rings 8 (preferably made of stainless steel). The four pull rings 8 are movably fitted onto four seat fixing members 7. Specifically, there is a gap between the horizontal part 742 of the seat fixing member 7 and the top surface of the baffle 73 for the pull rings 8 to pass through. The pull rings 8 are fitted onto the column body 741. The pull rings can be removed from the gap between the horizontal part 742 and the top surface of the baffle 73, thereby removing the seat (chair fabric).

[0040] The backrest tube 3 and the front seat tube 2 have the same shape. When the folding chair is unfolded, both the backrest tube 3 and the front seat tube 2 extend horizontally outward from the center of the folding chair, then tilt downward, and then bend upward. Foot pads 22 are installed on the lowest part of the bottom surface of the backrest tube 3 and the front seat tube 2.

[0041] In this embodiment, the two backrest tubes are respectively inserted into the insertion part of the first mounting base 11 and the insertion part of the second mounting base 12 located at the tail end. There are three second mounting bases, and the two front seat tubes are respectively inserted into the insertion parts of the two second mounting bases. The tubes and folding components of this folding hanging chair are all connected by insertion, and the folding component has a total of four insertion parts, any one of which can be inserted into either the backrest tube or the front seat tube.

[0042] The first mounting base 11 includes a hinge portion 9, a plug portion 10, and an anti-rotation portion 13. The plug portion 10 and the anti-rotation portion 13 are horizontally connected to the outer and inner sides of the hinge portion 9, respectively. The two horizontal ends of the hinge portion 9 are used to hinge with the second mounting base 12 located at the front end and the second mounting base 12 located at the rear end, respectively. The plug portion 10 is interference-fitted with the front tube 2 of the base.

[0043] In this embodiment, there are three second mounting seats 12. One second mounting seat 12 is connected to the front seat tube 2, and the other two second mounting seats 12 are connected to the two backrest tubes 3 respectively. The anti-rotation part 13 and the hinge part 9 are combined to form a T-shape. The anti-rotation part 13 has three vertical surfaces. When the folding chair is in the unfolded state, the three vertical surfaces are in contact with the inner side of the hinge part 9 of the three second mounting seats 12 respectively. The anti-rotation part 13 serves as the center of the folding assembly 1, and all the second mounting seats 12 are surrounded by the anti-rotation part 13, which restricts the rotation angle of all the second mounting seats 12. The hinge part 9 of the first mounting seat 11 and the hinge parts 9 of the three second mounting seats 12 form a square. In other embodiments, the number of second mounting seats 12 is not limited to three, and correspondingly, the number of vertical surfaces of the anti-rotation part 13 is the same as the number of second mounting seats 12.

[0044] The second mounting base 12 includes a hinge portion 9 and a plug portion 10. The hinge portion 9 has matching hinge structures (grooves 14 and protrusions 15) at both horizontal ends. The plug portion 10 is horizontally connected to the outside of the hinge portion 9. The plug portion 10 is inserted into one end of the front tube 2 or one end of the back tube 3. The plug portion 10 is interference-fitted with the front tube 2 or the back tube 3.

[0045] The hinge portion 9 of the first mounting base 11 has the same structure as the hinge portion 9 of the second mounting base 12. The two horizontal ends of the hinge portion 9 are respectively provided with a groove 14 and a protrusion 15. The protrusion 15 matches the groove 14. Each protrusion 15 is inserted into the adjacent groove 14 in the horizontal direction. The upper and lower groove walls of the groove 14 are provided with opposite hinge holes 16. The protrusion 15 is provided with a vertical hinge hole 16.

[0046] The protrusion 15 of the first mounting base 11 is inserted into the groove 14 of the second mounting base 12 located at the first end. The first mounting base 11 and the second mounting base 12 located at the first end are hinged by a pivot (not shown). Adjacent second mounting bases 12 are hinged by pivots. The pivots are inserted into the hinge holes 16 of the corresponding grooves 14 and the hinge holes 16 of the protrusions 15.

[0047] In other embodiments, the hinge structure between the first mounting base 11 and the second mounting base 12, as well as between adjacent second mounting bases 12, is not limited to this. For example, each of the horizontal ends of each second mounting base 12 is provided with a protrusion 15 with a hinge hole 16. The protrusions 15 of two adjacent second mounting bases 12 are stacked on top of each other, and the hinge of the two protrusions 15 can be achieved by inserting the rotating shaft into the hinge hole 16 of the two protrusions 15.

[0048] The insertion portion 10 of the first mounting base 11 has the same structure as the insertion portion 10 of the second mounting base 12. Preferably, the insertion portion 10 is a horizontally arranged cylinder with raised ribs 17 evenly (or unevenly) distributed along the circumference of its outer surface. The outer surface of the raised ribs 17 forms an interference fit with the front tube 2 or the backrest tube 3. The raised ribs 17 on the surface of the insertion portion 10 reduce the contact area between the front tube 2 or the backrest tube 3 and the insertion portion 10, which helps to reduce the frictional resistance when inserting the insertion portion 10 into the front tube 2 or the backrest tube 3.

[0049] A locking assembly is installed on the first mounting base 11 for connecting the first mounting base 11 to the second mounting base 12 located at the tail end.

[0050] The first mounting base 11 has a vertical mounting hole 18. The locking assembly includes a button 19, a spring 20, and a locking rod 21. The locking rod 21 includes a first vertical section 211, a horizontal section 212, and a second vertical section 213 connected in sequence. The first vertical section 211 is located in the mounting hole 18. The button 19 is installed on the upper end of the first vertical section 211 by thread (or welding, interference fit, or other methods). The horizontal section 212 of the locking rod 21 is located on the bottom surface of the first mounting base 11. The second vertical section 213 is inserted into the groove 14 from bottom to top through the hinge hole 16 in the lower groove wall of the groove 14. The end face of the second vertical section 213 is a slope 214 (for guiding). The spring 20 is located in the mounting hole 18 and pushes against the button 19 and the first mounting base 11 to provide an upward pulling force for the locking rod 21. By pressing down button 19, locking lever 21 moves downward, and second vertical segment 213 moves downward. Then, the protrusion 15 of the second mounting base 12 at the tail end is inserted into the groove 14 of the first mounting base 11. Then, button 19 is released, and spring 20 rebounds, pushing button 19 upward. Button 19 moves locking lever 21 upward, and the second vertical segment 213 of locking lever 21 inserts into the hinge hole 16 on the protrusion 15 of the second mounting base 12 at the tail end. At this time, folding assembly 1 is fully unfolded, and the folding chair is in an unfolded, usable state. In this embodiment, mounting hole 18 is provided on anti-rotation part 13. In other embodiments, mounting hole 18 can also be provided on other parts such as hinge part 9.

[0051] The folding hanging chair provided in this embodiment has a simple structure, small folded volume, high space utilization, and smooth rotation, unfolding, and folding. One person can complete the installation. The folding hanging chair provided in this embodiment has excellent comfort, greatly satisfying the user experience, and has an aesthetically pleasing design. The components are highly interchangeable (the backrest tube 3 and the front seat tube 2 have the same structure), resulting in low cost.
