[0023] 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.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1 to 6 This embodiment provides a multi-position adjustable folding chair (hereinafter referred to as folding chair) for outdoor activities, and has multiple positions to adjust the sitting height of the folding chair.

[0026] like Figure 1 As shown, the folding chair in this embodiment includes a chair fabric, a base 1, and four support arms 2 and legs 3 rotatably connected to the base 1. The support arms 2 and legs 3 are arranged vertically, with each support arm 2 corresponding to one of the legs 3. The support arms 2 support the chair fabric, and the legs 3 support the ground. The four support arms 2 are used to cover the four corners of the chair fabric. Of course, the tension of the chair fabric itself can be used to limit the unfolding angle of the four support arms 2.

[0027] like Figure 6 As shown, the folding chair in this embodiment also includes a multi-position adjustment structure 31 disposed on the support leg 3. The multi-position adjustment structure 31 includes a first stop part 311 and a second stop part 312.

[0028] like Figure 2 As shown, the first stop 311 corresponds only to the abutment wall 121 of the base 1 and is only used to restrict the movement of the first stop 311 to form the first position or low position of the folding chair, thereby reducing the seating height of the folding chair to the lowest level.

[0029] like Figure 3As shown, an elastic limiting component 5 is provided in the base 1. The second stop 312 corresponds only to the limiting part 52 of the elastic limiting component 5 and is only used to restrict the movement of the second stop 312 to form the second position or high position of the folding chair, thereby increasing the sitting height of the folding chair.

[0030] When the folding chair is unfolded, the support leg 3 rotates relative to the base 1. During the process of switching from the first stop 311 to the second stop 312, the support leg 3 and the limiting part 52 are spaced apart to ensure that the support leg 3 and the limiting part 52 do not contact each other and thus do not participate in the shifting action of the folding chair from the first gear to the second gear.

[0031] In this embodiment, as Figure 3 As shown, a torsion spring 4 is provided between the support leg 3 and the base 1, and the torsion spring 4 is used to support the support leg 3 outward by its own elastic force.

[0032] like Figure 6 As shown, each leg 3 has a stop groove and a limiting step arranged at intervals on the outer peripheral surface near the upper end of the base 1. At this time, the groove wall of the stop groove is the first stop part 311, and the limiting step is the second stop part 312.

[0033] like Figure 3 As shown, the elastic limiting component 5 includes a spring 51 and a movable limiting block 52'. The base 1 has a mounting groove 112 that matches the movable limiting block 52'. The movable limiting block 52' is movably mounted in the mounting groove 112. The spring 51 is disposed between the base 1 and the movable limiting block 52'. At this time, the movable limiting block 52' is the limiting part 52 of the elastic limiting component 5.

[0034] When the folding chair is switched to the second position, the spring 51 applies a spring force to the movable limit block 52' toward the support leg 3, so that the movable limit block 52' is engaged with the second stop part 312.

[0035] When the folding chair is in the first position, the movable limit block 52' is released from the restriction of the second stop part 312 and does not contact the support leg 3, so as to ensure that the elastic limit component 5 will not participate in the shifting process during the subsequent switching from the first position to the second position.

[0036] Through the cooperation of the multi-position adjustment structure 31, the abutment wall 121, and the limiting part 52, the folding chair of this embodiment has at least a first position and a second position for adjusting the support height of the support leg 3, thereby adjusting the seating height of the folding chair. Furthermore, the switching process from the first position to the second position does not require pressing a reset button, making operation more convenient and ensuring that... Figure 4 The overall folded and stored structure has a small footprint.

[0037] Of course, in other embodiments, the multi-position adjustment structure 31 may also have a third stop or other stop to achieve more adjustments to the sitting height; and the number of support arms 2 and support legs 3 is not limited to this.

[0038] In another preferred embodiment, such as Figure 3 As shown, the elastic limiting component 5 also includes a reset rod 53 (i.e., a reset button), which is movably inserted into the base 1 and connected to the movable limiting block 52' for resetting the movable limiting block 52'.

[0039] Further preferred, such as Figure 5 As shown, the base 1 has a first connecting part 11 and a second connecting part 12, and the first connecting part 11 and the second connecting part 12 are integrally formed, which makes subsequent assembly easier.

[0040] The outer peripheral surface of the first connecting part 11 has four first pivot grooves 111 arranged at intervals, and the second connecting part 12 has four second pivot grooves 122 that connect to the corresponding first pivot grooves 111. Each support arm 2 is pivotally connected to the corresponding first pivot groove 111, and each support leg 3 is pivotally connected to the corresponding second pivot groove 122.

[0041] More specifically, the four outriggers 2 include two front outriggers and two rear outriggers. The length of the two front outriggers is shorter than the length of the two rear outriggers, and both the front and rear outriggers adopt a telescopic structure, such as the front outriggers having two telescopic joints and the rear outriggers having three telescopic joints.

[0042] like Figure 4 and Figure 6 As shown, the cross-section of the four legs 3 is H-shaped to ensure sufficient mechanical strength, and each leg 3 has a storage groove 32 on its outward side to accommodate the corresponding support arm 2. When the folding chair is folded, the four support arms 2 are folded into the storage groove 32 of the corresponding leg 3.

[0043] In this specific embodiment, such as Figure 5 As shown, the first connecting part 11 and the second connecting part 12 together enclose a hollow receiving cavity 13. The first pivot groove 111, the second pivot groove 122, and the mounting groove 112 are all connected to the receiving cavity 13. The bottom wall of the receiving cavity 13 has an upwardly protruding abutment wall 121. At this time, the bottom of the first connecting part 11 has as shown in the figure. Figure 3 The mounting groove 112 shown has a second connecting part 12 with an abutment wall 121.

[0044] When the folding chair changes from the folded state to the unfolded state, all the support legs 3 rotate outward and unfold on their own under the elastic force of the torsion spring 4 until the first stop part 311 abuts against the abutment wall 121 of the base 1. At this time, the folding chair is in the first position or the low position.

[0045] When it is necessary to switch the folding chair from the first position to the second position, the user only needs to step on the support leg 3 with his foot and simultaneously lift the support arm 2, so that the support leg 3 rotates around the base 1 at a certain angle until the movable limit block 52' is engaged with the second stop part 312. At this time, the folding chair is in the second position or the high position.

[0046] When switching back to the first position from the second position or when folding the chair, the reset lever 53 needs to be pressed to drive the movable limit block 52' to reset and release the engagement between the movable limit block 52' and the second stop part 312, that is, to release the locking relationship between the elastic limit component 5 and the support leg 3.

[0047] Further preferred, such as Figure 6 As shown, each leg 3 is provided with a toothed part 33 that is relatively distributed at the upper end near the base 1. At this time, the outer peripheral surface of the upper end of each leg 3 has an arc-shaped wall, and the toothed part 33 is used to mesh with each adjacent two legs 3 so that multiple legs 3 are linked together and form a toothed linkage structure, thus ensuring that all legs 3 are deployed at the same time and their deployment angles are consistent.

[0048] In a further preferred embodiment, the lower end of the support leg 3 facing away from the base 1 is provided with an anti-slip pad to achieve an anti-slip effect.

[0049] Further preferably, the support leg 3 is equipped with straps, such as Velcro, to facilitate securing the folding chair when it is folded up.

[0050] Furthermore, each support arm 2 is equipped with plastic plugs at both the upper and lower ends to improve the overall aesthetics.

[0051] 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.
