[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 5 This embodiment provides a Kermit chair with a footrest (hereinafter referred to as the Kermit chair) as a portable folding chair suitable for outdoor activities, which can also take into account the comfort of the feet being supported, and especially can achieve a comfortable lying posture for the whole body.

[0024] like Figure 1 and Figure 2 As shown, the Kermit chair in this embodiment includes a backrest 1, a seat 2, armrests 3, a footrest 4, a front leg tube 5, and a rear leg tube 6, which together form a foldable structure to achieve overall unfolding or folding.

[0025] A linkage assembly 7 is provided between the backrest 1 and the footrest 4. The front leg tube 5 includes a straight part 51 for supporting the ground and a bent part 52 for rotatably connecting the seat 2, so that the front leg tube 5 is configured as a bent shape.

[0026] The linkage assembly 7 includes a first linkage 71 for rotatably connecting the footrest 4 and a second linkage 72 for rotatably connecting the backrest 1. The first linkage 71 is connected away from the rear end of the footrest 4 and the second linkage 72 is connected away from the front end of the backrest 1 to form a movable rotatable connection point 73, so that the backrest 1 and the footrest 4 can be linked to unfold and fold through the linkage assembly 7.

[0027] In this embodiment, a limiting groove 711 is provided at the rear end of the first link 71 near the second link 72. The first link 71 and the second link 72 are rotatably connected by a hinge shaft. The hinge shaft is movably inserted through the limiting groove 711, that is, the hinge shaft can slide within the limiting groove 711. The first link 71 and the second link 72 can rotate around the hinge shaft. At this time, the hinge shaft is the rotation connection point 73.

[0028] like Figure 5 As shown, by setting the front leg tube 5 as a whole in a bent shape, the ends of each leg tube can be made to form a flat surface after folding, thus ensuring that the Kermit chair can stand stably or be placed upright when folded. Figure 4 As shown, the linkage assembly 7 enables the chair back 1 and footrest 4 to unfold and fold in tandem. That is, while rotating the chair back 1, the folding angle of the footrest 4 can be adjusted, which makes it convenient for users to use in daily life.

[0029] Of course, in other embodiments, the front end of the second link 72 may also be provided with a limiting groove 711.

[0030] In another preferred embodiment, two front leg support rods 8 are provided between the seat 2 and the front leg tube 5 to further ensure the structural strength of the Kermit chair frame.

[0031] like Figure 1 As shown, a first sliding sleeve 9 and a second sliding sleeve 10 are respectively fitted on the two straight sections 51 and the first connecting rod 71. The two ends of each front foot support rod 8 are rotatably connected to the seat 2 and the first sliding sleeve 9, respectively, and the middle part of the front foot support rod 8 is rotatably connected to the second sliding sleeve 10. The first sliding sleeve 9 and the second sliding sleeve 10 are used to restrict the movement direction of the first connecting rod 71.

[0032] The bent portions 52 of the rear leg tube 6 and the front leg tube 5 are respectively hinged to the upper end of the armrest 3 to form a first pivot point 101. The first pivot point 101 is restricted by the position adjustment member 31 of the armrest 3 to form a multi-position adjustment, and is used to adjust the unfolding angle of the backrest 1 and the footrest 4 when they are stably supported.

[0033] More specifically, such as Figure 1 As shown, the gear adjustment component 31 has a gear adjustment groove 311. The groove wall of the gear adjustment groove 311 has multiple limiting recesses, such as 4 limiting recesses, which correspond to 4 adjustment gears. The first pivot point 101 is movably assembled in the gear adjustment groove 311. When it is stably supported, the first pivot point 101 can be detachably engaged with one of the limiting recesses to form a stably supported position.

[0034] In this specific embodiment, a foldable first cross tube unit 81 is rotatably connected between the two front foot support rods 8 to facilitate the folding of the two front foot support rods 8.

[0035] The chair back 1 includes two backrest rods 11 spaced apart and a second cross tube unit 12 rotatably connected between the two backrest rods 11. The second cross tube unit 12 is foldable to accommodate the folding of the two backrest rods 11, and the rear end of the second connecting rod 72 is rotatably connected to the lower end of the backrest rods 11.

[0036] The seat 2 includes two seat posts 21 spaced apart, and the two ends of the front leg support rod 8 are rotatably connected to the seat posts 21.

[0037] The footrest 4 includes two footrest rods 41 spaced apart. The rear end of the seat rod 21 is rotatably connected to the corresponding backrest rod 11 and forms a second pivot point 102. The front end of the seat rod 21 is rotatably connected to the upper end of the corresponding footrest rod 41. The middle part of the front foot tube 5 is rotatably connected to the seat rod 21. The rear foot tube 6 is rotatably connected to the second pivot point 102 via a swing rod 103. The rear end of the armrest 3 is rotatably connected to the corresponding backrest rod 11.

[0038] In addition, a third link 42 and a fourth link 43 are provided between the two foot support rods 41. The outward ends of the third link 42 and the fourth link 43 are rotatably connected to the two foot support rods 41, and the inward ends of the third link 42 and the fourth link 43 are rotatably connected to the hinge seat 44 to cooperate with the folding of the two foot support rods 41.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, when in use, the chair back 1 is rotated and adjusted to a certain angle, and the footrest 4 will also rotate to a certain angle. That is, the chair back 1 and the footrest 4 are linked and unfolded through the linkage assembly 7.

[0040] like Figure 5 As shown, when the Kermit chair is fully folded up, the footrest 4 will also fold along with the chair back 1 under the action of the linkage assembly 7. That is, the chair back 1 and the footrest 4 achieve linkage folding through the linkage assembly 7.

[0041] Under the combined constraints of the limiting slide groove 711 and the rotating connection point 73, the first link 71 and the second link 72 can simultaneously control the folding angle and travel of the footrest 4 when the chair back 1 is folded, thereby ensuring that the chair back 1 and the footrest 4 can be gathered and folded at the same time. This also avoids the phenomenon that the footrest rod 41 folds to the front foot support rod 8 first when folding, but the backrest rod 11 has not yet been fully folded.

[0042] Furthermore, the unfolding angle of the footrest 4 can be changed accordingly with the unfolding angle of the chair back 1, so as to achieve... Figure 2 The sitting posture angle shown is changed to, for example Figure 3As shown in the reclining angle, when the user is sitting on the Kermit chair and lifts the armrest 3, the backrest 1 leans back to increase the backrest tilt angle of the backrest 1. At the same time, the extension angle of the footrest 41 is increased through the linkage assembly 7. This can improve the user's comfort, safety and portability.

[0043] In summary, the Kermit chair of this embodiment has a small overall volume after folding and can stand upright on its own. When unfolded, the footrest 4 can be used to rest the feet, and the position adjustment component 31 of the armrest 3 can be used to simultaneously switch the position of the backrest 1 and the footrest 4 in different unfolded states.

[0044] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
