[0087] The present disclosure will be described in detail below with reference to the attached drawings.

[0088] Figures 1 to 4 show an embodiment of a high chair 1 according to an aspect of the present disclosure. It should be appreciated that while the high chair 1 shown in the figures is a child chair, the high chair 1 according to the present disclosure can also be a chair for adults, such as a high chair for a bar.

[0089] For ease of description, as shown in Figures 1 and 4, the direction that a child faces when seated in the high chair 1 is defined as the front, and the direction that the child faces away from is defined as the back. The direction that is perpendicular to the front-back direction on a horizontal plane is defined as the left-right direction or the lateral width direction of the seat.

[0090] As shown in Figures 1 to 4, the high chair 1 can include a seat 100 and legs connected to the seat 100, which are pivotable relative to the seat 100 to enable the high chair 1 to be unfolded and folded. Specifically, the legs can include front legs 200 and rear legs 300. In some embodiments, the front legs 200 are fixedly connected to the seat 100, while the rear legs 300 are pivotally connected to the seat 100 to enable the high chair 1 to be unfolded and folded. Of course, it is also possible that the front legs 200 are pivotally connected to the seat 100, while the rear legs 300 are fixedly connected to the seat 100; and, the front legs 200 are pivotally connected to the seat 100, while the rear legs 300 are also pivotally connected to the seat 100. The present disclosure is not limited thereto. It is also possible that the legs can include a left leg and a right leg, one of which is fixedly connected to the seat 100, while the other is pivotally connected to the seat 100, which also enables the high chair 1 to be unfolded and folded.

[0091] In some embodiments, the high chair 1 includes two front legs 200 and two rear legs 300, as shown in Figures 1 to 4, but it should be appreciated that the high chair 1 can also include other numbers of front legs 200 and rear legs 300, such as two front legs 200 and one rear leg 300, or one front leg 200 and two rear legs 300.

[0092] To prolong the service time of the high chair 1, the front leg 200 of the high chair 1 according to the present disclosure can comprise a front leg upper section 210 and a front leg lower section 220 which are detachably connected to each other, and the rear leg 300 can comprise a rear leg upper section 310 and a rear leg lower section 320 which are detachably connected to each other. In this way, the high chair 1 has three modes of use. Specifically, when the front leg upper section 210 and the front leg lower section 220 connected together form the front leg 200, the rear leg upper section 310 and the rear leg lower section 320 connected together form the rear leg 300, and when the tray 700 and the armrest 600 to be described later are connected to the seat 100, the high chair 1 is in a first mode of use at a high height, for example, suitable for use as a dining chair when the child is small. When the front leg upper section 210 and the front leg lower section 220 connected together form the front leg 200, the rear leg upper section 310 and the rear leg lower section 320 connected together form the rear leg 300, and the tray 700 and the armrest 600 are detached from the seat 100, the high chair 1 is in a second mode of use at a high height, for example, suitable for use as a dining chair when the child is older. When the front leg upper section 210 and the front leg lower section 220 are detached so that only the front leg upper section 210 forms the front leg 200, and the rear leg upper section 310 and the rear leg lower section 320 are detached so that only the rear leg upper section 310 forms the rear leg 300, the high chair 1 is in a third mode of use at a low height, for example, suitable for use as a play chair when the child is older.

[0093] To facilitate the storage of the high chair 1, it is necessary to enable the high chair 1 to be folded. In some embodiments, the front leg 200 is fixedly connected to the seat 100, and the rear leg 300 is connected to a connecting member 400 which is rotatably connected to the seat 100, thereby causing the rear leg 300 to also rotate relative to the seat 100 to fold and unfold.

[0094] In some embodiments, as shown in FIG. 10, the connecting member 400 is rotatably connected to the seat 100 via a connecting shaft 110. Specifically, the connecting member 400 is connected to one end of the rear leg 300, and the connecting member 400 is provided with a connecting member connecting hole 420. Correspondingly, the bottom of the seat 100 is provided with the connecting shaft 110. The connecting shaft 110 can be connected to the seat 100 by passing through a hole in the bottom of the seat 100. In one embodiment, the connecting shaft 110 can be provided on a fixing seat 510 of a locking device 500 to be described later. By passing the connecting shaft 110 into the connecting member connecting hole 420 on the connecting member 400, the connecting member 400 and the rear leg 300 connected thereto can rotate relative to the seat 100.

[0095] As shown in FIG. 10, in the case where the rear leg 300 is pivotally connected to the seat 100 via the connecting member 400, the connecting member connecting hole 420 is located in front of the locking hole 410 to be described later, so as to facilitate the locking of the rear leg 300 in the unfolded position. It should be understood that in the case where the front leg 200 is pivotally connected to the seat 100 via the connecting member 400, the connecting member connecting hole 420 can be located behind the locking hole 410, so as to facilitate the locking of the front leg 200 in the unfolded position.

[0096] Of course, the connecting member 400 can also be rotatably connected to the seat 100 in other ways. For example, the connecting member 400 is provided with a connecting shaft, and the bottom of the seat 100 is provided with a connecting hole through which the connecting shaft passes. Alternatively, the connecting member 400 is provided with a cylindrical protrusion, and the bottom of the seat 100 is provided with a cylindrical recess that accommodates the protrusion and allows the protrusion to rotate therein, and the connecting member 400 is rotatably connected to the seat 100 by the cooperation of the protrusion and the recess.

[0097] Since the rear leg 300 can rotate relative to the seat 100 via the connecting member 400, when the rear leg 300 is rotated relative to the seat 100 to a position away from the front leg 200, the high chair 1 is in an unfolded use state, as shown in FIG. 1; when the rear leg 300 is rotated relative to the seat 100 to a position close to the front leg 200, the high chair 1 is in a folded storage state, as shown in FIG. 6, thereby achieving the purpose of saving storage space, and in addition, the high chair 1 can be stood after being folded, which is convenient for storage.

[0098] Of course, the present disclosure is not limited thereto. In other embodiments, the rear leg 300 can be fixedly connected to the seat 100, and the front leg 200 is rotatably connected to the seat 100 via the connecting member 400, which can also achieve the purpose of saving storage space.

[0099] In order to control the rotation of the connecting member 400 relative to the seat 100, the high chair 1 according to the present disclosure can also include a locking device 500, which is provided on the seat 100 and can be operated to allow or prevent the connecting member 400 from rotating relative to the seat 100.

[0100] FIGS. 8 to 10 show an embodiment of the locking device 500 according to the present disclosure.

[0101] In this embodiment, the locking device 500 comprises a locking member 520 movably connected to the seat 100 and movable relative to the connecting member 400 along a first direction D1 (see Figs. 8 and 9) between a locking position and an unlocking position, the first direction D1 being, for example, the lateral width direction of the seat 100, i.e. the locking member 520 is movable along the lateral width direction of the seat 100. As shown in Fig. 8, when the locking member 520 is in the locking position, it extends into or inserts into the locking hole 410 on the connecting member 400, thereby preventing the connecting member 400 from rotating the rear legs 300 relative to the seat 100 to maintain the high chair 1 in the unfolded state or the collapsed state. As shown in Fig. 9, when the locking member 520 is in the unlocking position, it exits the locking hole 410 on the connecting member 400, thereby allowing the connecting member 400 to rotate the rear legs 300 relative to the seat 100 to enable the high chair 1 to be converted between the unfolded state and the collapsed state. In this embodiment, the locking hole 410 is located rearward of the connecting hole 420 on the connecting member 400, thereby facilitating the collapsing and rearward unfolding of the rear legs 300. In other embodiments in which the front legs 200 are pivotally collapsible, the locking hole 410 can be located forward of the connecting hole 420, thereby facilitating the collapsing and forward unfolding of the front legs 200.

[0102] Although in the embodiment shown in Figs. 8 to 10, only one set of locking holes 410 is shown for maintaining the high chair 1 in the unfolded state when the locking member 520 is inserted into the locking hole 410. However, in other embodiments, multiple sets of locking holes 410 can be provided on the connecting member 400 so that the rear legs 300 can be maintained at multiple rotational positions relative to the seat 100 when the locking member 520 is inserted into different sets of locking holes 410, thereby maintaining the high chair 1 in the collapsed state, the unfolded state, and intermediate states between the collapsed state and the unfolded state.

[0103] When the high chair 1 is maintained in the collapsed state, as shown in Fig. 6, the high chair 1 can be stood upright after being collapsed, thereby facilitating storage.

[0104] In some embodiments, as shown in Fig. 10, the locking device 500 can further comprise a fixed seat 510 fixedly connected to the seat 100, and the locking member 520 is movably connected to the fixed seat 510. Generally, the fixed seat 510 is located at the bottom or the back of the seat 100. Of course, the fixed seat 510 can be located at other positions of the seat 100 as desired. In some embodiments, the fixed seat 510 can also be integrally formed with the seat 100, i.e. the fixed seat 510 can not be additionally provided to be connected to the seat 100.

[0105] In order to facilitate the movement of the locking member 520, in some embodiments, the locking device 500 can further comprise an operating member 530, which is movably connected to the fixed seat 510 and can drive the locking member 520 to move. Specifically, the operating member 530 can move relative to the seat 100 along a second direction D2 (see FIGS. 8 and 9) to drive the locking member 520 to move along a first direction D1 between the locking position and the release position. In some embodiments, the first direction D1 is the lateral direction of the seat, and the second direction D2 is the height direction of the seat, i.e., the vertical direction perpendicular to the horizontal plane. Of course, the second direction D2 can also be at an angle to the horizontal plane, and the function of the operating member 530 driving the locking member 520 to move according to the present disclosure can also be achieved.

[0106] FIGS. 11 and 12 show an embodiment of the locking member 520 and the operating member 530 according to the present disclosure. As shown in FIGS. 11 and 12, the locking member 520 comprises a first locking member 521 and a second locking member 522 which are relatively movable. The first locking member 521 and the second locking member 522 are respectively provided with a protrusion along the relative movement direction, which can be respectively inserted into the corresponding locking hole 410. In this embodiment, the first locking member 521 and the second locking member 522 adopt a sleeve structure of mutual sleeving. It should be understood that the first locking member 521 and the second locking member 522 can adopt other cooperating structures, for example, one of them is provided with a guide groove, and the other is provided with a guide rail, and the relative movement of the two is achieved through the cooperating structure of the guide groove and the guide rail.

[0107] In order to enable the movement of the operating member 530 to drive the locking member 520 to move, the first locking member 521 is provided with a first cooperating inclined surface 521A (see FIG. 12), and the second locking member 522 is provided with a second cooperating inclined surface 522A (see FIG. 12). Correspondingly, the operating member 530 is provided with a first driving inclined surface 531 (see FIG. 12) which abuts against the first cooperating inclined surface 521A, and a second driving inclined surface 532 (see FIG. 11) which abuts against the second cooperating inclined surface 522A.

[0108] In the embodiment shown in FIGS. 11 and 12, the operating member 530 can take the structure of a button for facilitating user operation. When the operating member 530 is operated (i.e., the user exerts a pressing force on the operating member 530) to move (e.g., upwardly), the first driving slope 531 and the second driving slope 532 exert forces on the first mating slope 521 A on the first locking member 521 and the second mating slope 522A on the second locking member 522, respectively, to drive the first locking member 521 and the second locking member 522 to move toward each other to the release position. Thus, as shown in FIG. 9, the locking member 520 exits the locking hole 410 on the connecting member 400, allowing the connecting member 400 to drive the leg to rotate relative to the seat 100.

[0109] As shown in FIG. 12, the locking device 500 can further include a locking elastic member 540, which can be disposed between the first locking member 521 and the second locking member 522, for example, so as to be arranged to tend to move the first locking member 521 and the second locking member 522 away from each other to the locking position and keep them in the locking position, thereby preventing the connecting member 400 from rotating relative to the seat 100. Thus, when the operating member 530 is not operated (i.e., the user does not exert a force on the operating member 530), the locking elastic member 540 will drive the first locking member 521 and the second locking member 522 to move away from each other. In this process, the first mating slope 521 A on the first locking member 521 and the second mating slope 522A on the second locking member 522 will exert forces on the first driving slope 531 and the second driving slope 532 of the operating member 530, respectively, to drive the operating member 530 to move to the initial position, so as to be ready for the next release of the locking device 500.

[0110] The locking elastic member 540 can take the form of a spring, a gas pressure rod, or a hydraulic rod.

[0111] When the high chair 1 is unfolded, the high chair 1 can be in an incomplete unfolded state. In an embodiment, preferably, to prevent the high chair 1 from being in such an incomplete unfolded state, the high chair 1 can further be provided with a folding limiting mechanism, so that the high chair 1 can only be switched between the fully unfolded state shown in FIG. 42 and the folding state shown in FIG. 43, to avoid the incomplete unfolded state.

[0112] As shown in FIGS. 45 to 47, the high chair 1 provided with the folding limiting mechanism is basically the same as the high chair 1 shown in FIGS. 8 to 12, except that the folding limiting mechanism is added.

[0113] In one embodiment, the folding limiting mechanism according to the present disclosure can comprise a folding elastic member 111 disposed between the connecting member 400 and the seat 100 and tending to rotate the connecting member 400 relative to the seat 100 towards the folded position. In other embodiments, the folding elastic member 111 is also disposed between the connecting member 400 and the seat 100 and tending to rotate the connecting member 400 relative to the seat 100 towards the unfolded position.

[0114] In the embodiments shown in FIGS. 48-50 and 53-55, the folding elastic member 111 is a torsion spring 111 sleeved on the connecting shaft 110. Of course, the folding elastic member 111 according to the present disclosure can also take other elastic members such as a tensile spring or a tensile rod, as long as it can tend to rotate the connecting member 400 relative to the seat 100 towards the folded position.

[0115] As shown in FIG. 53, the first end 111A of the torsion spring 111 is connected to the connecting portion 490 of the connecting member 400, and the second end 111B of the torsion spring 111 is connected to the seat 100.

[0116] In one embodiment, the first end 111A of the torsion spring 111 is connected to the torsion spring fixing protrusion 491 (see FIG. 53) on the connecting portion 490 of the connecting member 400. The second end 111B of the torsion spring 111 abuts between the fixing column 172 and the inner side wall 171 in the mounting groove 170 of the seat 100 (see FIG. 55).

[0117] Since the folding elastic member 111 tends to rotate the connecting member 400 relative to the seat 100 towards the folded position, once the high chair 1 does not reach the unfolded state, the folding elastic member 111 will drive the high chair 1 into the folded state, avoiding the high chair 1 being in an incomplete unfolded state between the unfolded state and the folded state.

[0118] In one embodiment, preferably, the folding limiting mechanism can further comprise a limiting member movably disposed on the seat. The limiting member can take the structure of a limiting rod or a limiting protrusion.

[0119] In the embodiment shown in FIGS. 47-52, the limiters include first and second limiters 521B and 522B, respectively, disposed on the first and second lockers 521 and 522, respectively, and substantially parallel to the first and second locking portions 521C and 522C, respectively, and configured to follow the first and second lockers 521 and 522, respectively, to extend in the first direction D1 (see FIG. 47) relative to the seat 100 and to block the connection member 400 from rotating from the collapsed position to the expanded position when extended. In other embodiments, the first and second limiters 521B and 522B can be configured to block the connection member 400 from rotating from the expanded position to the collapsed position. In addition, it is understood that the number of limiters is not limited to two, and the limiters can include only one limiter disposed on either the first or second locker 521 or 522, or a plurality of limiters disposed on both the first and second lockers 521 and 522.

[0120] In an alternative embodiment, the limiters can not be provided separately, and at least one of the first and second locking portions 521C and 522C can be additionally configured to block the connection member from rotating from the collapsed position to the expanded position, as shown in FIG. 51B.

[0121] In this case, taking the second locking portion 522C shown in FIG. 51B as an example, the second locking portion 522C appears as an obliquely extending strip-shaped structure in the left-right direction, and in particular, the second locking portion 522C obliquely extends from bottom to top in the front-rear direction. The second locking portion 522C is sized such that, when the connection member 400 and the rear leg 300 are in the collapsed position and the second locking portion 522C is in the extended state, the second locking portion 522C blocks the connection member 400 from rotating from the collapsed position to the expanded position.

[0122] Of course, the present disclosure is not limited thereto. The second locking portion 522C can also take other suitable structures such as a cylindrical shape. In addition, the first locking portion 521C can have the same or different structure as the second locking portion 522C.

[0123] When the high chair 1 is in the collapsed state, the second limiter 522B follows the second locker 522 to be in the extended state (as shown in FIG. 51A), and the first limiter 521B likewise follows the first locker 521 to be in the extended state (not shown), so that the second limiter 522B and the first limiter 521B block the upper side edge of the connection member 400, so that the connection member 400 cannot rotate toward the collapsed position.

[0124] When the user is ready to switch the high chair 1 to the unfolded state, a force can be applied to the operating member 530, which then drives the second locking member 522 and the first locking member 521 to move and retract, so that the second limiting member 522B following the second locking member 522 and the first limiting member 521B following the first locking member 521 also retract. Thus, the connecting member 400 is no longer blocked by the second limiting member 522B and the first limiting member 521B and can rotate towards the unfolded position.

[0125] The connecting member 400 is provided with connecting member limiting holes 480 that cooperate with the second limiting member 522B and the first limiting member 521B, respectively. When the connecting member 400 rotates to the unfolded position, as shown in FIG. 52, the first locking portion 521C and the second locking portion 522C can extend and be inserted into the corresponding locking holes 410 on the connecting member 400. At the same time, the second limiting member 522B and the first limiting member 521B can also extend and be inserted into the corresponding connecting member limiting holes 480 on the connecting member 400, so as to keep the high chair 1 in the unfolded state. In other embodiments, alternatively, when the connecting member 400 rotates to the unfolded position, the locking portions extend into the corresponding locking holes, and the limiting members extend into the corresponding connecting member limiting holes.

[0126] In the embodiment shown in FIG. 51B, which does not provide a separate limiting member, it is also unnecessary to provide a separate connecting member limiting hole. In this case, the locking hole 410 can additionally serve as a connecting member limiting hole. When the second locking portion 522C is inserted into the corresponding locking hole 410 on the connecting member 400, the high chair 1 can be kept in the unfolded state.

[0127] In the case where the folding elastic member 111 is provided, if the second locking member 522 and the first locking member 521 are blocked by the connecting member and do not extend and are not inserted into the corresponding locking holes 410 on the connecting member 400 (correspondingly, the second limiting member 522B and the first limiting member 521B are also not inserted into the corresponding connecting member limiting holes 480 on the connecting member 400), the connecting member 400 will rotate towards the folded position under the elastic force of the folding elastic member 111, thereby avoiding the high chair 1 from being in an incomplete unfolded state.

[0128] It should be understood that the locking device 500 according to the present disclosure is not limited thereto.

[0129] In other embodiments, the locking member 520 and the operating member 530 can adopt other cooperating structures. For example, the operating member 530 can be a knob with a gear at one end, and the locking member 520 is a rack engaged with the gear. When the user rotates the operating member 530 to rotate the gear at one end, the rotation of the gear is converted into the movement of the rack through the engagement of the gear and the rack, thereby driving the locking member 520 to move. In other embodiments, the locking device 500 can not be provided with the operating member 530, and the locking member 520 has a portion that can be contacted by the user, thereby allowing the user to directly contact and move the locking member 520. In other embodiments, the locking device 500 can even not adopt the way that the locking member 520 is inserted into or withdrawn from the locking hole 410 on the connecting member 400 to prevent or allow the connecting member 400 to rotate relative to the seat 100, but can adopt other ways. For example, one of the connecting member 400 and the seat 100 is provided with a hook, and the other is provided with a ring. When the connecting member 400 is rotated to the appropriate position relative to the seat 100, the relative rotation between the two is prevented or allowed by hooking or unhooking the hook from the ring.

[0130] In some embodiments, in order to facilitate the user to perform the unfolding action of the high chair 1, as shown in FIG. 10, the connecting member 400 can be provided with a guide slope 430 extending from the upper end of the connecting member 400 to the locking hole 410 or to the vicinity of the locking hole 410 along a direction inclined to the upper end, so that when the high chair 1 is in the folded state, the locking member 520 is in the extended state and abuts against the upper end of the guide slope 430; when the high chair 1 is unfolded, as the legs and the connecting member 400 perform the unfolding action, the locking member 520 is pressed by the guide slope 430 and slides along the guide slope 430 relative to the connecting member 400 to the locking hole 410, and then the locking member 520 is extended under the elastic force of the locking elastic member 540 and inserted into the locking hole 410. Thus, the user only needs to pull the legs to complete the unfolding action of the high chair 1, without the need to operate the operating member 530.

[0131] In some embodiments, as shown in FIGS. 10, 24 and 26, the upper end of the connecting member 400 can also be provided with an abutting upper edge 440. When the connecting member 400 and the rear legs 300 connected thereto are rotated to the unfolded position, the abutting upper edge 440 abuts against the bottom of the seat 100. On the one hand, the abutting upper edge 440 can limit the rotation angle of the connecting member 400 and the rear legs 300 connected thereto towards the unfolded position; on the other hand, the abutting upper edge 440 of the connecting member 400 is supported by the bottom of the seat 100, which can improve the stability of the high chair 1 in the unfolded state.

[0132] In some embodiments, as shown in FIG. 10, FIG. 24, and FIG. 26, the bottom of the seat 100 can be provided with a limiting wall 130 extending outwardly from the bottom, which is arranged to abut against the connecting member 400 when the connecting member 400 and the rear legs 300 connected thereto are rotated to the unfolded position, so as to limit the connecting member 400 from further rotating in the same direction (see FIG. 24). Therefore, the limiting wall 130 can also limit the rotation angle of the connecting member 400 and the rear legs 300 connected thereto towards the unfolded position, and can enable the connecting member 400 to be supported by the bottom of the seat 100, so as to improve the stability of the high chair 1 in the unfolded state.

[0133] In some embodiments, as shown in FIG. 24 and FIG. 26, the bottom of the seat 100 can be further provided with a limiting rib 140 and a guiding rib 150 extending outwardly from the bottom, the guiding rib 150 being located in front of the limiting rib 140, and forming a space between the two for the connecting member front edge 450 of the connecting member 400 to move therein, and being arranged such that, when the connecting member 400 and the rear legs 300 connected thereto are rotated to the unfolded position, the limiting rib 140 is spaced apart from the connecting member front edge 450 of the connecting member 400 in the front-rear direction so as not to interfere with each other (see FIG. 24), and the connecting member front edge 450 is close to the guiding rib 150; when the connecting member 400 and the rear legs 300 connected thereto are rotated to the folded position, the connecting member front edge 450 of the connecting member 400 is guided by the guiding rib 150 to abut against the limiting rib 140, so as to limit the connecting member 400 from further rotating in the same direction (see FIG. 26). Therefore, the limiting rib 140 can limit the rotation angle of the connecting member 400 and the rear legs 300 connected thereto towards the folded position, and can improve the stability of the high chair 1 in the folded state.

[0134] In some embodiments, as shown in FIG. 27, the bottom of the seat 100 can be provided with a limiting intermediate portion 160 arranged to be located between the two connecting member front edges 450 of the connecting member 400. Correspondingly, the connecting member 400 is provided with a connecting member limiting portion 460 located below the limiting intermediate portion 160. When the connecting member 400 and the rear legs 300 connected thereto are rotated to the folded position, the limiting intermediate portion 160 abuts against the connecting member limiting portion 460, so as to limit the connecting member 400 from further rotating in the same direction, thereby limiting the rotation angle of the connecting member 400 and the rear legs 300 connected thereto towards the folded position, and can improve the stability of the high chair 1 in the folded state.

[0135] FIG. 35 to FIG. 41 show a locking device 500I according to another embodiment of the present disclosure.

[0136] In this embodiment, as shown in FIG. 36, the locking device 500I comprises a locking member 520I movably connected to the seat 100 and movable relative to the connecting member 400 along a third direction D3 (see FIG. 40) between a locking position and a releasing position. As shown in FIGS. 37, 38, 40 and 41, the locking member 520I is provided with a locking portion 523I. The third direction D3 is, for example, the front-to-rear direction of the seat 100, i.e. the locking member 520I is movable along the front-to-rear direction of the seat 100. In an embodiment, the upper end surface of the locking portion 523I extends along the third direction D3, i.e. parallel to the horizontal plane.

[0137] Correspondingly, as shown in FIGS. 39 to 41, the connecting member 400I is provided with a connecting member locking rod 470I. In order to control the rotation of the connecting member 400I relative to the seat 100, the connecting member locking rod 470I and the locking portion 523I are arranged such that, when the locking member 520I is moved to the locking position, as shown in FIG. 40, in the unfolded state of the seat 100, the upper end of the locking portion 523I can block the connecting member locking rod 470I so that the connecting member 400I and the rear legs 300 connected thereto cannot be rotated relative to the seat 100 to the folded position within a certain range or within a certain limit; when the locking member 520I is moved to the releasing position, as shown in FIG. 41, in the unfolded state of the seat 100, the locking portion 523I no longer blocks the connecting member locking rod 470I so that the connecting member 400I and the rear legs 300 connected thereto can be rotated relative to the seat 100 to the folded position about the connecting shaft 110 (see FIG. 38).

[0138] Specifically, in the unfolded state of the seat 100, the upper end surface of the locking portion 523I can tightly abut against the connecting member locking rod 470I, so that the upper end surface of the locking portion 523I can completely block the connecting member locking rod 470I so that it cannot be rotated at all. Alternatively, in the unfolded state of the seat 100, the upper end surface of the locking portion 523I can also have a certain gap with the connecting member locking rod 470I, so that the connecting member locking rod 470I has a very small amount of rotation space, and after it is rotated by a small angle towards the folded position, it is blocked by the upper end surface of the locking portion 523I and cannot continue to rotate.

[0139] In the present disclosure, when the high chair 1 is in the folded state, the connecting member 400 is correspondingly in the folded position, and when the high chair 1 is in the unfolded state, the connecting member 400 is correspondingly in the unfolded position.

[0140] In an embodiment, the lower end surface 524I of the locking portion 523I is a sloped surface. Specifically, the lower end surface 524I of the locking portion 523I is a sloped surface extending from lower to upper along a front-to-back direction. Thus, in the folded state of the seat 100, when the rear leg 300 is forced to move towards the unfolded position, the connector locking rod 470I abuts against the sloped lower end surface 524I of the locking portion 523I and moves the locking member 520I along the third direction D3 towards the releasing position, thereby allowing the connector locking rod 470I to continuously rotate towards the unfolded position, and allowing the connector locking rod 470I, the connector 400I and the rear leg 300 connected thereto to finally rotate to the unfolded position without additional forward force applied to the locking member 520I.

[0141] It is appreciated that in other embodiments, the lower end surface 524I of the locking portion 523I can extend along the third direction D3, i.e. parallel to the horizontal plane. In this case, when the rear leg 300 is in the folded position and is forced to rotate backwards, the lower end surface 524I of the locking portion 523I will block the movement of the connector locking rod 470I, thereby blocking the rotation of the rear leg 300, so that the rear leg 300 cannot rotate to the unfolded position. Thus, when the rear leg 300 is in the folded position and needs to be unfolded, a forward force needs to be applied to the locking member 520I so that the rear leg 300 can be rotated to unfold after the locking member 520I reaches the releasing position.

[0142] In an embodiment, in order to facilitate the movement of the locking member 520I between the locking position and the releasing position, in the embodiment shown in FIGS. 39-41, the locking device 500I can further comprise an operating member 530I movably connected to the connector 400I along the third direction D3 and capable of driving the locking member 520I to move between the locking position and the releasing position when operated.

[0143] As shown in FIG. 40, the operating member side wall 533I of the operating member 530I can abut against the right end surface 525I of the locking portion 523I of the locking member 520I, so that when the operating member 530I is pressed towards the inside along the third direction D3, the operating member 530I pushes the locking member 520I to move from the locking position to the releasing position.

[0144] In the present embodiment, the lower end surface 524I of the locking member 520I is a sloped surface, and the end of the operating member 530I abuts against the sloped surface 524I. In other embodiments, additionally, the lower end surface 524I of the locking member 520I is a sloped surface and can comprise a recess, the shape of which matches the shape of the end of the operating member 530I (see the dashed line in FIGS. 40 and 41), so that the operating member 530I can better push the locking member 520I to move.

[0145] On the other hand, the operating member 530I can also be operated to be retracted toward the outside in the third direction D3 to the initial position. The operating member 530I and the locking member 520I can be connected by a flexible intermediate member (not shown) so that when the operating member 530I is retracted toward the outside in the third direction D3, the operating member 530I drives the locking member 520I to move from the released position to the locked position.

[0146] In another embodiment, in order to facilitate the user's operation, a second locking elastic member (not shown) can be provided between the bottom of the seat 100 and the locking member 520I, which is arranged to tend to move the locking member 520I from the released position to the locked position and in the process drive the operating member 530I to be retracted toward the outside in the third direction D3 to the initial position.

[0147] As shown in FIG. 45, the bottom end of the front leg 200 can be provided with a front foot pad 201, and the bottom end of the rear leg 200 can be provided with a rear foot pad 201, to reduce the noise generated between the high chair 1 and the ground. In addition, the front foot pad 201 and the rear foot pad 201 can be provided with support inclined surfaces, so that the high chair 1 is more stably supported.

[0148] In the embodiment shown in FIG. 14, the high chair 1 can further include an armrest 600 detachably connected to the seat 100. When a smaller child (for example, a baby greater than 6 months old) sits on the high chair 1, as shown in FIG. 1, the armrest 600 can be connected to the seat 100 to protect the smaller child from accidentally falling off the seat 100, and to connect articles such as a tray 700 (to be described later) on the armrest 600. When a larger child (for example, a child greater than 3 years old) sits on the high chair 1, as shown in FIG. 2, the seat 100 can not necessarily be connected to the armrest 600, and the child can have more freedom.

[0149] The armrest 600 can include an armrest engaging portion 610 capable of engaging with a seat connecting portion 120 on the seat 100. In the embodiment shown in FIG. 15, the armrest engaging portion 610 is in the form of a cover at both ends, which can cooperate with the seat connecting portion 120 (see FIGS. 2 and 16) in the form of a protrusion on both sides of the seat 100, so that the armrest 600 can be conveniently and quickly connected to the seat 100.

[0150] In some embodiments, to strengthen the connection between the armrest 600 and the seat 100, the armrest joint 610 can be provided with an armrest connecting piece 611 that can be inserted into a seat connecting hole 121 (see FIG. 16) on the seat joint 120, as shown in FIG. 15. In the embodiment shown in FIG. 15, the armrest connecting piece 611 is located inside the cap-shaped armrest joint 610 and extends downward, and the seat connecting hole 121 is formed through the protrusion-shaped seat joint 120 (see FIG. 16) and can be inserted into the armrest connecting piece 611.

[0151] Further, as shown in FIG. 15, the armrest connecting piece 611 of the armrest joint 610 can be provided with a connecting piece engaging hole 612. Correspondingly, as shown in FIG. 16, the inner wall of the seat connecting hole 121 of the seat joint 120 is provided with a connecting hole finger 122, which is flexible and extends outward from the inner wall of the seat connecting hole 121 in the form of a cantilever. As shown in FIG. 18, since the connecting hole finger 122 is flexible and has a tapered structure at the end, when the armrest connecting piece 611 is inserted into the seat connecting hole 121, the tapered structure of the connecting hole finger 122 allows the armrest connecting piece 611 to be inserted into the seat connecting hole 121, but once the connecting piece engaging hole 612 engages with the connecting hole finger 122, the tapered structure of the connecting hole finger 122 will prevent the armrest connecting piece 611 from exiting the seat connecting hole 121. With the engagement of the connecting piece engaging hole 612 and the connecting hole finger 122, the accidental disengagement of the armrest 600 from the seat 100 can be effectively avoided, thereby ensuring the safety of the child seated on the seat 100.

[0152] In addition, as shown in FIG. 18, the inside of the seat joint 120 is hollow and open at the lower part, so that the armrest connecting piece 611 inserted into the seat connecting hole 121 can be exposed at the lower part of the seat joint 120. In this way, the user can contact the armrest connecting piece 611 from the lower opening of the seat joint 120 and apply a force to it to disengage the armrest connecting piece 611 from the connecting hole finger 122, thereby allowing the armrest connecting piece 611 to exit the seat connecting hole 121 and then allowing the armrest 600 to be detached from the seat 100.

[0153] The armrest connecting piece 611 can be formed integrally with the armrest joint 610 or separately formed.

[0154] In another embodiment of the armrest 600 shown in FIG. 56, the armrest connecting piece 611, on which the connecting piece engaging hole 612 is formed, is a single member that is separately formed and can be fixed to the armrest joint 610 by a connecting piece fastener 613 such as a screw or a rivet. In this way, once the armrest connecting piece 611 loses flexibility due to long-term use, the armrest connecting piece 611 can be replaced, thereby avoiding the replacement of the entire armrest 600.

[0155] Correspondingly, as shown in FIG. 58, a connecting hole engaging tab 124 is extended downwardly from the edge of the seat connecting hole 121, and the engaging tab finger 125 is formed on the connecting hole engaging tab 124, which is arranged to be engaged with the connecting tab engaging hole 612 on the armrest connecting tab 611 (see FIG. 59), so as to prevent the armrest connecting tab 611 from exiting the seat connecting hole 121, thereby avoiding the armrest 600 from being accidentally detached from the seat 100.

[0156] In order to further strengthen the connection between the armrest 600 and the seat 100, the armrest sleeve 610 can also be provided with a connecting tab limiting hook 614, as shown in FIG. 56, which can be inserted into the seat limiting hole 123 on the seat connecting portion 120 (see FIGS. 57 and 58), and forms a reverse fitting with the seat 100, thereby further fixing the armrest 600 to the seat 100.

[0157] In the embodiment shown in FIG. 1, the high chair 1 can also include a tray 700, which is detachably connected to the armrest 600. The tray 700 can greatly expand the functions of the high chair 1, which can not only be used as a child's dining tray to place the child's dishes or food thereon, but also be used as a child's operating table to place the child's toys thereon.

[0158] In order to fix the tray 700 relative to the armrest 600 after being installed on the armrest 600, as shown in FIG. 13, the tray 700 is provided with a tray engaging block 710, which is movable along the transverse width direction of the seat 100 between an engaging position and a disengaging position, and the tray engaging block 710 further includes a tray engaging protrusion 711 protruding inwardly along the transverse width direction of the seat 100. Correspondingly, as shown in FIG. 14, the armrest 600 is provided with an armrest recess 620. When the tray engaging block 710 is moved to the engaging position, the tray engaging protrusion 711 on the tray engaging block 710 is engaged with the armrest recess 620 on the armrest 600. In some embodiments, a plurality of armrest recesses 620 can be provided on the armrest 600, and the tray engaging block 710 can selectively engage with different armrest recesses 620, so as to adjust the relative position of the tray 700 and the seat 100, so as to be more suitable for use by children of different body shapes.

[0159] Further, as shown in FIG. 18, the tray 700 can be provided with a tray elastic member 720, which is arranged to tend to move the tray engaging block 710 to the engaging position. In this way, the relative fixation between the tray 700 and the armrest 600 can be ensured.

[0160] Optionally, the surface of the tray engaging protrusion 711 is inclined. When it is required to mount the tray 700 to the armrest 600, the tray 700 is aligned with the armrest 600 and the tray engaging protrusion 711 is abutted against the upper end of the armrest 600, a downward force is applied to the tray 700, due to the effect of the inclination, the tray engaging protrusion 711 will move outward along the transverse direction, so that the tray 700 continues to move downward, when the tray 700 is moved downward to the position, the tray engaging protrusion 711 is extended into the armrest recess 620 under the action of the tray elastic member 720, thereby completing the engagement of the tray 700 and the armrest 600. When it is required to move the tray 700 away from the armrest 600, the user can operate the tray engaging block 710 to move to the disengagement position, the tray engaging protrusion 711 is disengaged from the armrest recess 620, thereby releasing the relative fixation between the tray 700 and the armrest 600.

[0161] In some embodiments, the high chair 1 can include two front legs 200, and a footrest 800 is detachably connected between the two front legs 200 for the child to step on, thereby increasing the comfort of the child.

[0162] As shown in FIGS. 19 and 20, the footrest 800 according to the present disclosure can include a footrest body 810 and connecting ears 820. The footrest body 810 extends along the transverse direction of the seat 100 between the two front legs 200, and constitutes the main body of the footrest 800. The connecting ears 820 protrude from both ends of the footrest body 810 in a direction perpendicular to the extension direction of the footrest body 810.

[0163] The design of the connecting ears 820 prolongs the effective use time of the footrest 800. When the connecting ears 820 are connected to the front legs 200 via footrest connecting members 830 (which are, for example, connecting bolts), the footrest body 810 can be flipped up and down. Specifically, the footrest 800 has two installation positions. The first installation position is that the connecting ears 820 are located below the footrest body 810, as shown in FIG. 19, which makes the footrest body 810 closer to the seat 100, suitable for when the child is younger. The second installation position is that the connecting ears 820 are located above the footrest body 810, as shown in FIG. 21, which makes the footrest body 810 farther away from the seat 100, suitable for when the child is older. The footrest body 810 can be flipped up and down between the first installation position and the second installation position to meet the needs of children at different stages.

[0164] In some embodiments, as shown in FIG. 22, preferably, the front leg 200 is provided with a front leg connecting seat 230 for connecting with the connecting lug 820 of the footrest 800 to connect the footrest 800 to the front leg 200. The front leg connecting seat 230 is designed to be wide at the bottom and narrow at the top, so that the two front legs remain parallel, facilitating the installation of the footrest. In some embodiments, preferably, the surface of the connecting lug 820 that cooperates with the front leg connecting seat 230, i.e. the end surface that faces outward in the transverse direction of the seat 100, extends vertically, and the surface of the front leg connecting seat 230 that cooperates with the connecting lug 820, i.e. the surface that faces inward in the transverse direction of the seat, extends vertically. In this way, the connection between the connecting lug 820 and the front leg connecting seat 230 is more stable, and the connecting lug 820 can be flipped up and down more smoothly, facilitating the switching of use modes. In some embodiments, the outer end surface of the connecting lug 820 is provided with a square-shaped protrusion 821 (see FIG. 20), and the inner side of the front leg connecting seat 230 is provided with a square-shaped recess 231 (see FIG. 22), which cooperate to prevent the footrest body 810 from accidentally flipping between the first installation position and the second installation position after the footrest 800 is installed.

[0165] The front leg connecting seat 230 can be fixed to the front leg 200 by means of fasteners such as screws, as shown in FIG. 33.

[0166] FIGS. 28-34 show another embodiment of the footrest 800 according to the present disclosure. In this embodiment, the structure of the connecting lug 820 of the footrest 800, and the connection structure of the footrest 800 and the front leg 200 are different from the foregoing embodiments, and are described as follows.

[0167] In this embodiment, as shown in FIGS. 28-30 and 33-34, the footrest connecting member 830 can include a footrest locking piece 831 provided on the front leg connecting seat 230, which is movably arranged on the front leg connecting seat 230 and can be extended and retracted along the extension direction of the footrest body 810.

[0168] In the embodiment shown in FIG. 33, the inner side of the footrest locking piece 831 can be provided with a reset elastic member 832 that tends to extend the footrest locking piece 831 along the extension direction of the footrest body 810. The reset elastic member 832 can be an elastic member such as a spring, a gas pressure rod, or a hydraulic rod.

[0169] Correspondingly, as shown in FIGS. 31 and 32, the footrest connecting member 830 also includes a through footrest locking hole 822 provided on the connecting lug 820, which is sized and shaped to allow the footrest locking piece 831 to pass therethrough, so that the footrest locking piece 831 can be extended into and withdrawn from the footrest locking hole 822.

[0170] In other embodiments, alternatively, the pedal locking hole 822 can also be a non-through hole, but a blind hole provided on the connecting lug 820, which only extends through a part of the thickness of the connecting lug 820, i.e. in the extension direction of the pedal body 810, the pedal locking hole 822 only extends through a part of the connecting lug 820 instead of through the connecting lug 820. The pedal locking hole 822 arranged in this way can also achieve the engagement and disengagement of the pedal locking member 831 with the pedal locking hole 822.

[0171] When installing the pedal 800, the user only needs to press the pedal locking member 831 to retract it in the extension direction of the pedal body 810, and then align the pedal locking hole 822 on the connecting lug 820 with the pedal locking member 831. Then, after the user no longer presses the pedal locking member 831, the pedal locking member 831 can extend into the pedal locking hole 822 in the extension direction of the pedal body 810 under the elastic force of the reset spring 832, thereby completing the installation of the pedal 800.

[0172] When disassembling or adjusting the pedal 800, the user also only needs to press the pedal locking member 831 to retract it from the pedal locking hole 822 in the extension direction of the pedal body 810. Then, the user can disassemble the pedal 800, or flip the pedal body 810 up and down between the first installation position and the second installation position.

[0173] In other embodiments, alternatively, the pedal locking hole can be provided on the front leg connecting seat 230, the pedal locking member can be provided on the connecting lug 820, and the pedal locking member can be telescopic in the extension direction of the pedal body 810 to engage or disengage with the pedal locking hole. When it is necessary to install the pedal 800 or disassemble or adjust the pedal 800, the user also only needs to press the pedal locking member 831 to retract it so that the pedal locking member 831 engages with the pedal locking hole 822.

[0174] In other embodiments, alternatively, the pedal locking member 831 itself can be a deformable structure such as a spring, which deforms when pressed to reduce the size in the extension direction of the pedal body 810, thereby allowing the pedal locking member 831 to engage with the pedal locking hole 822 to connect the pedal 800 to the front leg connecting seat 230. In this embodiment, since the pedal locking member 831 itself is a deformable structure, there is no need to provide a reset spring. When it is necessary to install the pedal 800 or disassemble or adjust the pedal 800, the user also only needs to press the pedal locking member 831 to deform and retract it so that the pedal locking member engages with the pedal locking hole.

[0175] After the footrest 800 is installed, in order to ensure that the footrest body 810 does not accidentally flip between the first installation position and the second installation position, in the embodiment shown in FIGS. 30 to 34, a limiting block 232 can be provided on the front leg connecting seat 230. The limiting block 232 can be square (see FIG. 30) or oval, polygonal, or other shapes that can prevent the footrest body 810 from flipping.

[0176] In the embodiment shown in FIGS. 30, 33 and 34, the footrest locking member 831 can be provided at the limiting block 232. Specifically, as shown in FIG. 33, the footrest locking member 831 can pass through the substantially middle position of the limiting block 232 and be movably provided relative to the limiting block 232.

[0177] Correspondingly, as shown in FIGS. 31 and 32, the connecting ear 820 is provided with a limiting slot 823, which corresponds in size and shape to the limiting block 232, and the side edge of the limiting block 232 can be engaged in the limiting slot 823, so that the limiting block 232 can be engaged with the limiting slot 823 to limit the footrest 800 in at least one direction.

[0178] In addition, in order to facilitate the engagement of the limiting block 232 with the limiting slot 823, as shown in FIGS. 31 and 32, the limiting slot 823 is provided with a lateral opening 823A in at least one direction, that is, the limiting slot 823 is open in at least one direction, so that the limiting block 232 is inserted into the limiting slot 823 from the lateral opening 823A. In this case, by the cooperation of the limiting block 232 and the limiting slot 823, the footrest 800 can be limited in other directions except the direction in which the lateral opening 823A is provided.

[0179] Specifically, as shown in FIG. 31, when the footrest 800 is flipped to the lower position, the lateral opening 823A of the limiting slot 823 faces the front of the seat 100, at which time the footrest 800 can be inserted from the rear to the front of the limiting block 232, thereby installing the footrest 800 on the front leg 200. As shown in FIG. 32, when the footrest 800 is flipped to the higher position, the lateral opening 823A of the limiting slot 823 faces the rear of the seat 100, at which time the footrest 800 can be inserted from the front to the rear of the limiting block 232, thereby installing the footrest 800 on the front leg 200.

[0180] In other embodiments, alternatively, the limiting groove 823 can be opened towards other directions (i.e. the lateral opening 823A is towards other directions), for example, when the footrest 800 is flipped to the lower position, the limiting groove 823 is opened towards the upper or lower direction of the seat 100, at this time, the footrest 800 can be inserted into the limiting block 232 from the lower to the upper or from the upper to the lower, thereby installing the footrest 800 to the front leg 200. It can be understood that other opening directions of the limiting groove 823 can also be conceived, for example, the limiting groove 823 is opened in a slanting direction, at this time, the insertion direction of the footrest 800 to the limiting block 232 is slanting.

[0181] In other embodiments, alternatively, the limiting groove 823 can also be provided with two lateral openings, or in other words, opened towards two directions, for example, when the footrest 800 is flipped to the lower position or the higher position, the limiting groove 823 is opened towards the front-rear direction of the seat 100, at this time, the footrest 800 can be inserted into the limiting block 232 from the front to the rear or from the rear to the front; or alternatively, when the footrest 800 is flipped to the lower position or the higher position, the limiting groove 823 is opened towards the up-down direction of the seat 100, at this time, the footrest 800 can be inserted into the limiting block 232 from the upper to the lower or from the lower to the upper. It can also be understood that the limiting groove 823 can also be opened in a slanting direction.

[0182] In other embodiments, alternatively, the limiting block 232 can also be provided on the connecting lug 820, while the limiting groove can be provided on the front leg connecting seat 230, thereby achieving the connection of the footrest 800 to the front leg connecting seat 230.

[0183] In addition, since the limiting block 232 and the limiting groove 823 are both square or elliptical or polygonal, after the engagement of the two, the limiting groove 823 is limited by the limiting block 232 located therein and cannot be rotated, thereby achieving the non-flipping of the footrest body 810 where the limiting groove 823 is located.

[0184] In addition, in some embodiments, the footrest 800 can also have the function of accommodating the tray 700. As shown in FIG. 20, the two end surfaces of the footrest body 810 along the transverse direction of the seat 100 can be respectively provided with footrest engaging holes 840. Correspondingly, as shown in FIG. 13, the tray 700 is provided with a tray boss 730. The footrest engaging hole 840 can be engaged with the tray boss 730. When the tray 700 is detached from the armrest 600 and is not needed to be used, the tray 700 can be accommodated in the footrest 800 by means of the engagement of the footrest engaging hole 840 and the tray boss 730, thereby providing a storage position for the tray 700, and effectively preventing the tray 700 from being lost.

[0185] In some embodiments, the end surface of each end of the footrest body 810 is provided with two footrest engaging holes 840 spaced apart in the front-rear direction, preferably, the two footrest engaging holes 840 in the front-rear direction are located on both sides of the footrest connecting member 830, so that after the footrest body 810 is flipped up and down, no matter whether the footrest 800 is in the first installation position or in the second installation position, the tray 700 can be accommodated in the rear of the footrest 800, that is, between the front leg 200 and the rear leg 300. In this way, no matter whether the footrest 800 is in the first installation position or in the second installation position, the accommodation of the tray 700 in the footrest 800 will not hinder the normal use of the footrest, while improving the overall aesthetics of the product.

[0186] Another aspect of the present disclosure provides a locking device 500, which comprises a locking member 520 movably connected to an object to be locked and movable in a first direction D1 between a locked position and an unlocked position, the structure and characteristics of the locking member 520 are as described above. In some embodiments, the locking member 520 comprises a first locking member 521 and a second locking member 522 capable of relative movement, the structure and characteristics of the first locking member 521 and the second locking member 522 are as described above. The above-mentioned object to be locked can be the high chair described above, or other structures, such as a trolley, a sleeping bed, etc.

[0187] In some embodiments, the locking device 500 can further comprise a fixed seat 510 fixedly connected to the seat 100, and the locking member 520 is movably connected to the fixed seat 510, the structure and characteristics of the fixed seat 510 are as described above.

[0188] In some embodiments, the locking device 500 can further comprise an operating member 530 movably connected to the fixed seat 510 and capable of driving the locking member 520 to move, the structure and characteristics of the operating member 530 are as described above.

[0189] In some embodiments, the locking device 500 can further comprise a locking elastic member 540, which can be arranged between the first locking member 521 and the second locking member 522, so as to be arranged to tend to move the first locking member 521 and the second locking member 522 away from each other to the locked position and keep in the locked position, the structure and characteristics of the locking elastic member 540 are as described above.

[0190] Since the features of the present disclosure can be embodied in various forms, it should also be understood that the embodiments described above are not limited to only the described details but are capable of complying with the features of the present disclosure in various forms, and therefore, all modifications and alterations derived from the scope and range of the appended claims and their equivalents should be included in the appended claims.
