This utility model will now be further described with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 8 This embodiment provides a fully folding Kermit chair (hereinafter referred to as Kermit chair) for use in outdoor scenarios such as camping.

[0028] like Figure 1 and Figure 2 As shown, the Kermit chair in this embodiment includes two armrest tubes 1, a backrest tube 2, a seat tube 3, a front leg tube 4, a rear leg tube 5, and two hinged front cross tubes 6 and a rear cross tube 7. The two front leg tubes 4, the rear leg tube 5, the seat tube 3, and the backrest tube 2 are all straight tubes and are parallel to each other.

[0029] The lower ends of the two front cross tubes 6 are rotatably connected to the lower ends of the corresponding front leg tubes 4, the upper ends of the two front cross tubes 6 are rotatably connected to the front ends of the corresponding seat tubes 3, the upper ends of the two rear cross tubes 7 are rotatably connected to the upper ends of the corresponding back tubes 2, the lower ends of the two rear cross tubes 7 are rotatably connected to the rear ends of the corresponding seat tubes 3, and the lower ends of the two back tubes 2 are rotatably connected to the rear of the corresponding seat tubes 3. The upper ends of the two front leg tubes 4 and the rear leg tubes 5 are rotatably connected to the corresponding armrest tubes 1, and the two seat tubes 3 are rotatably connected to the corresponding front leg tubes 4.

[0030] Each of the two rear foot tubes 5 is fitted with a movable sliding sleeve 8, and the two sliding sleeves 8 are rotatably connected to the corresponding seat tube 3, forming a stable support when unfolded.

[0031] In this embodiment, the upper ends of the two front cross tubes 6 are respectively hinged to the front end of the corresponding seat tube 3 through a crescent-shaped connector.

[0032] The lower ends of the two front cross tubes 6 and the lower ends of the corresponding front foot tubes 4, as well as the lower ends of the two back tubes 2 and the rear parts of the corresponding seat tubes 3, are rotatably connected by U-shaped connectors.

[0033] The upper end of the rear cross tube 7 and the upper end of the back tube 2, as well as the lower end of the rear cross tube 7 and the rear end of the seat tube 3, are respectively hinged by L-shaped connectors 9.

[0034] In practice, the upper ends of the two front cross tubes 6 are respectively hinged to one end of the corresponding crescent-shaped connector, and the other ends of the two crescent-shaped connectors are respectively hinged to the front end of the corresponding seat tube 3.

[0035] The rear parts of the two seat tubes 3 are respectively fixed with first U-shaped connectors, and the ends of the two first U-shaped connectors opposite to the seat tubes 3 are respectively hinged to the lower ends of the corresponding back tubes 2.

[0036] The lower ends of the two front foot tubes 4 are respectively hinged to one end of the corresponding second U-shaped connector, and the other ends of the two second U-shaped connectors are respectively hinged to the lower end of the corresponding front cross tubes 6.

[0037] The upper and lower ends of the two rear cross tubes 7 are respectively hinged to one end of the corresponding L-shaped connector 9, and the upper ends of the two back tubes 2 and the rear ends of the two seat tubes 3 are respectively hinged to the other end of the corresponding L-shaped connector 9.

[0038] The foldable support frame is constructed from the armrest tube 1, back tube 2, seat tube 3, front leg tube 4, rear leg tube 5, front cross tube 6, and rear cross tube 7. With the assistance of movable sliding sleeves, it can be quickly folded down, forming a shape like... Figure 3 The folded state shown is such that neither the front leg tube 4 nor the rear leg tube 5 bends outward after folding, thus taking up little space and making it easy to store.

[0039] When deployed, the two intersecting rear cross tubes 7 can form a back support.

[0040] In another preferred embodiment, such as Figure 4 and Figure 5 As shown, the sliding sleeve 8 has an axially penetrating mounting cavity 81 and a hinge post 82 disposed on the outer wall of the mounting cavity 81. The hinge post 82 is provided with a hinge hole 821 extending along its axial direction. The rear leg tube 5 slides against the inner wall of the mounting cavity 81. The axial direction of the hinge hole 821 is perpendicular to the length direction of the rear leg tube 5, and as shown... Figure 1 As shown, the rear foot tube 5 is also fixed with a limiting member 11 for restricting the sliding sleeve 8 from sliding. Specifically, the limiting member 11 is a limiting sleeve. At this time, the limiting member 11 is sleeved on the rear foot tube 5 and located between the sliding sleeve 8 and the handrail tube 1.

[0041] When the Kermit chair in this embodiment switches between the folded and unfolded states, the sliding sleeve 8 slides up and down on the rear leg tube 5 to match the folding structure of the Kermit chair at different folding or unfolding angles. When fully unfolded, the limiting member 11 restricts the sliding sleeve 8 from continuing to slide upwards to further ensure reliable support.

[0042] Of course, in other embodiments, the limiting member 11 may also adopt a limiting pin structure or a limiting step structure.

[0043] More preferably, the number of rear cross pipes 7 is two, and includes, as follows: Figure 6 The first rear cross tube 7' shown and as shown Figure 7 The second rear cross pipe 7” is shown, while the first rear cross pipe 7’ is a straight pipe.

[0044] The second rear cross tube 7” includes two first straight sections 71 arranged at relative intervals, two broken line sections 72 connected to the first straight sections 71, and a second straight section 73 connected between the two broken line sections 72, and both broken line sections 72 are located between the first straight section 71 and the second straight section 73.

[0045] More specifically, the second rear cross tube 7” is bow-shaped, and the extension direction of the first straight section 71 is parallel to the extension direction of the second straight section 73.

[0046] Two first straight sections 71, two broken sections 72, and one second straight section 73 constitute an integrally formed structure, and the thickness interference of the first rear cross tube 7' is offset by bow-shaped compensation.

[0047] Of course, in other embodiments, one of the front crossing pipes 6 may be a straight pipe, and the other front crossing pipe 6 may have an arc-shaped structure.

[0048] Further preferred, such as Figure 8 As shown, the armrest tube 1 has an adjustable connector 10, and the upper ends of the front leg tube 4 and the rear leg tube 5 are respectively hinged to the adjustable connector 10 so that the user can finely adjust the unfolded posture.

[0049] In this specific embodiment, the upper and lower ends of the two rear cross tubes 7 and the upper ends of the two front leg tubes 4 and the rear leg tubes 5 are respectively provided with tube plugs, and the lower ends of the two front leg tubes 4 and the rear leg tubes 5 are respectively provided with foot pads to ensure overall aesthetics and more stable support without slipping.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
