[0022] Reference Figures 1 to 9A folding stool includes a seating section 100, a support leg 200, and a locking mechanism 300. The seating section 100 is provided with a leg hinge section 110 and an upper limit section 120. One end of the support leg 200 is hinged to the leg hinge section 110 and can be opened and folded relative to the seating section 100. A locking protrusion 210 is provided on the circumferential surface of one end of the support leg 200. The locking mechanism 300 includes a locking seat 310, a telescopic rod 320, and an elastic element 330. The locking seat 310 is fixed to the seating section 100. The telescopic rod 320 is movably disposed on the locking seat 310 along its length. One end of the telescopic rod 320 is provided with a lower limit section 321, and the other end of the telescopic rod 320 is provided with a handle section 322. The elastic element 330 is disposed between the locking seat 310 and the telescopic rod 320 and is used to make the telescopic rod 320 tend to move relative to the locking seat 310 toward the lower limit section 321. When the support leg 200 is opened relative to the seating part 100, the upper limit part 120 cooperates with the support leg 200 and limits the support leg 200 in the opening direction. The lower limit part 321 extends out and blocks the lower side of the latching protrusion 210 and limits the support leg 200 in the folding direction. After the telescopic rod 320 is pulled by the handle part 322, the lower limit part 321 can be moved away from the blocking position to allow the support leg 200 to fold.
[0023] In the aforementioned folding stool, when the support leg 200 is open, it is limited in both the opening and folding directions by the upper limit part 120 of the seating section 100 and the lower limit part 321 of the telescopic rod 320, thus maintaining stability in the open position. When folding is required, the handle part 322 is operated, causing the telescopic rod 320 to move, disengaging the lower limit part 321 from the locking protrusion 210, allowing the support leg 200 to fold. This folding stool utilizes the structure of the seating section 100 as the upper limit part 120, and the elastically extendable telescopic rod 320 lowerly limits and allows the locking protrusion 210 of the support leg 200 to be moved, thus enabling switching between maintaining the open state and allowing folding. The overall structure is simple, and folding is quick and convenient, requiring only the extension and retraction of the telescopic rod 320.
[0024] In this embodiment, the support leg 200 includes two front legs 200a and two rear legs 200b. The two front legs 200a are connected together by a front connector 400, and the two rear legs 200b are connected together by a rear connector 500. The two front legs 200a can be folded back and tucked under the seating portion 100, and the two rear legs 200b can be folded forward and tucked under the seating portion 100. With this structure, the two front legs 200a and the two rear legs 200b can be folded simultaneously via the front connector 400 and the rear connector 500, respectively, further simplifying operation. After folding, the front legs 200a and the rear legs 200b can be tucked under the seating portion 100, resulting in a small overall size and convenient transportation and storage.
[0025] In one embodiment, a locking mechanism 300 can be configured for positioning each individual front leg 200a and each individual hind leg 200b, thereby reducing operations. In some embodiments, a locking mechanism 300 can also be configured for positioning each front leg 200a and each hind leg 200b, depending on the actual situation.
[0026] In this embodiment, the front connector 400 and the rear connector 500 are rods, and their ends are fixed to the corresponding support legs 200.
[0027] It is conceivable that in other embodiments, the number of support legs 200 is not limited to the above-mentioned number. Those skilled in the art can reasonably configure the number of support legs 200 according to the actual situation.
[0028] In one embodiment, the distance between the two front legs 200a is less than the distance between the two hind legs 200b, and after the two front legs 200a and the two hind legs 200b are folded, the two front legs 200a can be folded between the two hind legs 200b. In other embodiments, the distance between the two front legs 200a can be greater than the distance between the two hind legs 200b, and after the two front legs 200a and the two hind legs 200b are folded, the two hind legs 200b can be folded between the two front legs 200a. Using the above structure, the front legs 200a and the hind legs 200b can be folded compactly, resulting in a small folded volume.
[0029] In this embodiment, the front leg 200a is tilted relative to the vertical direction and its lower part is further forward when it is opened, while the rear leg 200b is tilted relative to the vertical direction and its lower part is further back when it is opened, thereby forming a trapezoidal support structure, which effectively ensures the stability of the folding stool when it is opened.
[0030] In this embodiment, the seating section 100 is provided with a structural beam 130, and the upper end of the support leg 200 is provided with a hinge joint 220. The leg hinge part 110 is the horizontal sidewall of the structural beam 130, and the hinge joint 220 is hinged to the horizontal sidewall of the structural beam 130. The upper end of the support leg 200 is provided with a limiting mating surface 230, and the upper limit part 120 is the lower end surface of the structural beam 130. When the support leg 200 is opened, the lower end surface of the structural beam 130 can abut against the limiting mating surface 230 to limit the support leg 200. With the above structure, the sidewall and lower side surface of the structural beam 130 can be used as the leg hinge part 110 and the upper limit part 120, which is simple in structure and easy to manufacture and implement.
[0031] In this embodiment, the hinge joints 220 are arranged in pairs, with the two pairs of hinge joints 220 clamping both sides of the structural beam 130 and respectively hinged to the two opposite side walls of the structural beam 130 in the horizontal direction. With the above structure, the hinged structure of the support leg 200 and the structural beam 130 is stable.
[0032] In this embodiment, the structural beam 130 includes an outer sleeve 131 and an inner reinforcing tube 132. The outer sleeve 131 is fitted over the inner reinforcing tube 132, and the hinge joint 220 is hinged to both the outer sleeve 131 and the inner reinforcing tube 132. With the above structure, the hinged structure of the support leg 200 is stable.
[0033] In one embodiment, the two hinge joints 220 can be hinged to the structural beam 130 via a single hinge shaft, or they can be hinged separately via two coaxially arranged hinge shafts.
[0034] In this embodiment, the lower sidewall of the outer sleeve 131 has a lower insertion hole 1311, and the upper end face of the locking seat 310 has an insertion part 313. The insertion part 313 is adapted to the shape of the lower insertion hole 1311 and is inserted into the lower insertion hole 1311. The upper end face of the locking seat 310 abuts against the lower side face of the outer sleeve 131. Fasteners 600 pass through the inner reinforcing tube 132 and the insertion part 313, and the fasteners 600 lock the locking seat 310, the outer sleeve 131, and the inner reinforcing tube 132 together. With the above structure, the locking mechanism 300 is securely fixed.
[0035] In this embodiment, the lower sidewall of the inner reinforcing tube 132 has an upper insertion hole 1321, which is aligned with the lower insertion hole 1311 and adapted to the shape of the insertion part 313. The insertion part 313 is simultaneously inserted into both the upper insertion hole 1321 and the lower insertion hole 1311. With the above structure, the mutual fixation of the locking seat 310, the outer sleeve 131, and the inner reinforcing tube 132 is more secure.
[0036] In one embodiment, the seating section 100 includes a frame and a cover plate 140 covering the frame. The frame is formed by connecting multiple structural beams 130. In another embodiment, the two horizontal sides and the lower side of the inner reinforcing tube 132 are respectively fitted to the outer tube 131, and the upper side of the inner reinforcing tube 132 is spaced from the outer tube 131. The fastener 600 is a screw with the screw head accommodated in the aforementioned space, thereby forming a recessed and hidden structure that does not affect the connection between the cover plate 140 and the frame.
[0037] In one embodiment, the fastener 600 is a screw; in other embodiments, the fastener 600 may also be a structure such as a rivet, pin, etc.
[0038] In this embodiment, the upper surface of the latching protrusion 210 and the upper surface of the support leg 200 are coplanar and together form a limiting mating surface 230. When the support leg 200 is open, the upper limiting part 120 and the lower limiting part 321 clamp the latching protrusion 210. The above structure is compact. The latching protrusion 210 is clamped and limited by the upper limiting part 120 and the lower limiting part 321, which provides stable limiting for the support leg 200. In addition, the limiting mating surface 230 is jointly formed by the upper surface of the latching protrusion 210 and the upper surface of the support leg 200, and has a larger area, making the mating with the upper limiting part 120 more stable.
[0039] In this embodiment, the locking base 310 is provided with a sliding connection hole 311 that matches the shape of the lower limit portion 321. The sliding connection hole 311 is not circular. The lower limit portion 321 is slidably disposed in the sliding connection hole 311. The sliding connection hole 311 has a bottom and a through hole 312 is opened at the bottom. The telescopic rod 320 includes a connecting rod portion 323. The two ends of the connecting rod portion 323 are respectively connected to the lower limit portion 321 and the handle portion 322. The connecting rod portion 323 passes through the through hole 312. The elastic element 330 is disposed between the bottom of the sliding connection hole 311 and the lower limit portion 321. The specific structure of the locking mechanism 300 described above is simple and easy to manufacture and implement.
[0040] In this embodiment, the elastic element 330 is a spring. It is conceivable that in other embodiments, the elastic element 330 may also be other structures, such as elastic sheets or rubber bodies.
[0041] In this embodiment, the lower limit portion 321 is square. Of course, in some embodiments, the lower limit portion 321 is not limited to square. For example, it may be elliptical or other non-circular structures. The specific configuration can be made according to the actual situation.
[0042] In this embodiment, a backrest 700 is also included. The lower end of the backrest 700 is hinged to the seating portion 100, and the backrest 700 can be rotated and folded onto the upper side of the seating portion 100.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
