[0029] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 4 As shown, this embodiment provides a Kermit chair, which at least includes a chair cloth installation structure of the Kermit chair (hereinafter referred to as the chair cloth installation structure).

[0031] The chair cloth installation structure of this embodiment includes a Kermit chair body, which is used to install the chair cloth assembly. The Kermit chair body includes Figure 8 The seat tube 1 shown and Figure 9 The backrest tube 2 shown, the seat tube 1 and the backrest tube 2 respectively have two straight tubes set at a distance from each other, and an intermediate tube is connected between the two straight tubes of the seat tube 1 to form a U-shaped seat tube 1. The U-shaped opening direction of the seat tube 1 is set forward, and the chair cloth assembly includes a flexible chair cloth and mounting parts fixed at both ends of the chair cloth, and the specific mounting parts are mounting rod structures.

[0032] The chair cloth mounting structure of this embodiment also includes a support adjustment component 3. The two straight tubes of the seat tube 1 and the backrest tube 2 respectively have a mounting cavity 11 for assembling the mounting part. The circumferential wall of the mounting cavity 11 is provided with a clearance opening 111 for the chair cloth to pass through. The clearance opening 111 is set to open upward to facilitate the chair cloth to pass through the clearance opening 111. The mounting part can be detachably assembled in the mounting cavity 11, and the mounting part is restricted by the clearance opening 111, that is, the inner diameter of the clearance opening 111 is smaller than the outer diameter of the mounting part to ensure that the mounting part will not fall out of the clearance opening 111 when the Kermit chair is in use.

[0033] The front side of the seat tube 1 and the upward side of the backrest tube 2 respectively have elastically openable mounting openings 12. The U-shaped opening of the seat tube 1 and the upward opening of the backrest tube 2 are the mounting openings 12. The mounting openings 12 are equipped with support adjustment components 3 for adjusting their opening range to stretch or loosen the chair cloth, thereby facilitating quick disassembly and installation of the chair cloth component.

[0034] In this embodiment, Figure 1 The Kermit chair body shown includes a front leg tube 5, a rear leg tube 6 and an armrest 7. The front leg tube 5 and the rear leg tube 6 are also U-shaped, and the armrest 7 includes an armrest connector and an armrest fixed on the armrest connector.

[0035] The upper ends of the front leg tube 5 and the backrest tube 2 are respectively hinged to the front and rear ends of the armrest connecting member of the armrest member 7, the upper end of the rear leg tube 6 is hinged to the middle of the armrest connecting member of the armrest member 7, the middle of the front leg tube 5 is hinged to the middle of the seat tube 1, and a space is provided between the seat tube 1 and the backrest tube 2. Figure 7 The U-shaped first connecting member 8 shown has its lower end fixed to the seat tube 1 and its upper end hinged to the backrest tube 2. A second connecting member 9 is provided between the rear leg tube 6 and the backrest tube 2. The lower end of the second connecting member 9 is hinged to the rear leg tube 6 and its upper end is hinged to the backrest tube 2.

[0036] The front leg tube 5, the rear leg tube 6, the armrest 7, the seat tube 1 and the backrest tube 2 are connected to form a foldable and stable support structure. The angle between the seat tube 1 and the backrest tube 2 can be adjusted within a certain range through the rotation connection between the seat tube 1 and the backrest tube 2, thereby achieving corresponding adjustment of the inclination angle of the backrest tube 2 according to the different daily needs of the user, that is, expanding its scope of application to meet the needs of users with different body shapes and sitting habits.

[0037] By detachably inserting the mounting parts of the chair cloth assembly into the mounting cavities 11 of the seat tube 1 and the backrest tube 2, the chair cloth of the chair cloth assembly is simultaneously passed through the clearance opening 111 on the circumferential wall of the mounting cavity 11, and then adjusting the opening range of the mounting openings 12 of the seat tube 1 and the backrest tube 2 by the support adjustment assembly 3 to stretch or loosen the chair cloth, thereby facilitating the rapid disassembly and assembly of the chair cloth assembly. The chair cloth mounting structure of this embodiment eliminates the snap-fit ​​fixing structure in the prior art, which can avoid the occurrence of undesirable phenomena such as the snap-fit ​​loosening during use, and as Figure 5 The Kermit chair shown occupies little space after being folded, making it easy to carry and fold.

[0038] In another preferred embodiment, Figure 3 As shown, the support adjustment assembly 3 includes a rocker 31, a screw portion 32 and a nut portion 33. The two straight tubes of the seat tube 1 and the backrest tube 2 respectively have a fixing hole 13 for fixing the screw portion 32. The screw portion 32 is assembled in the fixing hole 13 to limit the circumferential rotation of the screw portion 32. Nut portions 33 are fixed to both ends of the rocker 31 facing the screw portion 32. The protruding portions of the screw portion 32 protruding from the fixing holes 13 are screwed to the nut portion 33. The rocker 31 is rotated, and the threaded connection between the screw portion 32 and the nut portion 33 is used to drive the nut portion 33 to make corresponding movements on the screw portion 32, thereby adjusting the opening amplitude of the corresponding mounting opening 12.

[0039] In this specific embodiment, the number of chair cloth assemblies and support adjustment assemblies 3 is two, the two chair cloth assemblies are respectively the first chair cloth assembly and the second chair cloth assembly which are independently set, the two support adjustment assemblies 3 are respectively the first support adjustment assembly and the second support adjustment assembly which are respectively independently set, the first chair cloth assembly and the first support adjustment assembly correspond to the seat tube 1 respectively, and the second chair cloth assembly and the second support adjustment assembly correspond to the backrest tube 2 respectively.

[0040] The seat tube 1 and the backrest tube 2 each have a plug-in cavity 14 therein. The mounting cavity 11 and the plug-in cavity 14 are spaced apart from each other to form a seat tube 1 and a backrest tube 2 with a cross-section in the shape of a Chinese character "LV". Plug-in ports 15 are respectively provided at the front ends of the seat tube 1 and the backrest tube 2 for connecting the mounting cavity 11 and the plug-in cavity 14 thereof.

[0041] The chair fabric installation structure of this embodiment further includes a pipe plug 4 for closing the plug port 15. Figure 6 The pipe plug 4 shown has an abutment portion 41 and a protruding insertion portion 42. The insertion portion 42 can be detachably inserted into the insertion cavity 14, and the mounting piece is restricted by the abutment portion 41 of the pipe plug 4 to restrict the mounting piece within the mounting cavity 11, thereby further ensuring that the chair cloth assembly will not detach from the seat tube 1 and the backrest tube 2.

[0042] When the first chair cloth assembly on the seat tube 1 needs to be removed, first pull out the pipe plug 4 from the plug interface 15 of the seat tube 1 by hand, and then rotate the rocker 31 of the first support adjustment assembly in the first direction by hand to drive the nut part 33 of the first support adjustment assembly to rotate accordingly. At the same time, the screw part 32 of the first support adjustment assembly is restricted in rotation by the corresponding fixing hole 13, and is threadedly connected to drive the nut part 33 of the first support adjustment assembly to move inward along the axial direction of the screw part 32 on the screw part 32 of the first support adjustment assembly, thereby reducing the opening amplitude of the mounting opening 12 of the seat tube 1. At this time, the chair cloth of the first chair cloth assembly is no longer stretched and tightened by the seat tube 1, but is in a relaxed state. Therefore, it is convenient for the user to first pull the mounting part of the first chair cloth assembly out of the mounting cavity 11 of the seat tube 1 in the axial direction, and simultaneously pull the chair cloth of the first chair cloth assembly out of the clearance opening 111 of the seat tube 1 to complete the quick disassembly of the first chair cloth assembly.

[0043] When a new chair cloth assembly needs to be installed on the seat tube 1, first insert the mounting piece of the first chair cloth assembly into the mounting cavity 11 of the seat tube 1, and at the same time, the chair cloth of the first chair cloth assembly passes through the clearance opening 111 of the seat tube 1. When the first chair cloth assembly is fully inserted into place, manually rotate the rocker 31 of the first support adjustment assembly in a second direction opposite to the first direction to drive the nut part 33 of the first support adjustment assembly to rotate accordingly. At the same time, the screw part 32 of the first support adjustment assembly is restricted in rotation by the corresponding fixing hole 13, and is threadedly connected to drive the nut part 33 of the first support adjustment assembly to move outward along the axial direction of the screw part 32 on the screw part 32 of the first support adjustment assembly, thereby increasing the opening amplitude of the mounting opening 12 of the seat tube 1 until the chair cloth of the first chair cloth assembly is stretched and tightened by the seat tube 1 to ensure that the first chair cloth assembly has sufficient support. Finally, the pipe plug 4 is re-inserted into the plug port 15 of the seat tube 1 to complete the quick installation of the first chair cloth assembly.

[0044] The second chair fabric assembly is quickly disassembled and assembled on the backrest tube 2 using the same disassembly and assembly method as described above, which will not be described in detail here.

[0045] By cooperating with the support adjustment component 3, the seat tube 1 and the backrest tube 2, the user can quickly remove and install the first chair cloth component and the second chair cloth component from the seat tube 1 and the backrest tube 2 respectively, so as to replace the new chair cloth component (such as a harder or weaker chair cloth material) to meet the user's requirements for the softness and hardness of different chair cloths, and no additional specific tools are required to remove and install the chair cloth components, which is especially convenient for outdoor use.

[0046] Of course, in other embodiments, the seat tube 1 is separately equipped with a support adjustment component 3, and the supporting chair cloth of the backrest tube 2 is fixed using the existing fixing method, so that the chair cloth component on the seat tube 1 can be quickly replaced, or the backrest tube 2 is separately equipped with a support adjustment component 3, and the supporting chair cloth of the seat tube 1 is fixed using the existing fixing method, so that the chair cloth component on the backrest tube 2 can be quickly replaced.

[0047] Furthermore, the installation positions of the screw portion 32 and the nut portion 33 are replaceable, so that the chair fabric assembly can be quickly disassembled and installed.

[0048] In addition, an elastic support rod assembly containing a spring can also be used to replace the support adjustment assembly 3 composed of the rocker 31, the screw portion 32 and the nut portion 33, and the opening range of the mounting opening 12 of the seat tube 1 and the backrest tube 2 can also be quickly adjusted to cooperate with the disassembly and installation of the chair cloth assembly.

[0049] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
