High chair

Abstract

This disclosure provides a high chair, comprising: a seat; a connector rotatably connected to the seat; legs connected to the connector; and a locking member movably connected to the seat along a first direction and movable relative to the connector between a locked position and an unlocked position. When the locking member is in the locked position, the connector cannot rotate relative to the seat; when the locking member is in the unlocked position, the connector can rotate relative to the seat. The rotation of the connector relative to the seat causes the legs to rotate relative to the seat, thereby enabling the high chair to switch between an unfolded state and a folded state. When not in use, the rear legs of the high chair according to this disclosure can be folded relative to the seat to save storage space. Furthermore, the high chair can stand upright after folding, making it convenient for storage.

Description

[Technical Field]

[0001] This disclosure relates to a high chair. [Previous Technology]

[0002] High chairs for children are generally designed for children's dining. To extend the lifespan of high chairs, existing high chairs typically have multiple usage modes. A high chair consists of a seat and supporting legs connected to the seat. These supporting legs are designed to be detachable in multiple sections, with different lengths connected to the seat. Combined with a tray, footrest, and other accessories, different usage modes are achieved. However, the supporting legs of existing children's high chairs are not foldable, resulting in a large footprint and inconvenient storage when not in use. [Summary of the Invention]

[0003] The purpose of this disclosure is to provide a high chair that avoids the aforementioned problems existing in the prior art.

[0004] As embodied and summarized herein, in order to achieve these and other advantages and for the purposes of this disclosure, one aspect of this disclosure provides a high chair comprising: a seat; a connector rotatably connected to the seat; a leg connected to the connector; and a locking member movably connected to the seat in a first direction and movable relative to the connector between a locked position and an unlocked position, wherein when the locking member is in the locked position, the connector cannot rotate relative to the seat, and when the locking member is in the unlocked position, the connector can rotate relative to the seat, and the rotation of the connector relative to the seat causes the leg to rotate relative to the seat, thereby enabling the high chair to switch between an unfolded state and a folded state.

[0005] In one embodiment, the high chair further includes an operating member movably connected to the seat in a second direction, which is different from the first direction, and the operating member, when operated, causes the locking member to move between the locked position and the unlocked position.

[0006] In one embodiment, the locking member is provided with a mating inclined surface, and the operating member is provided with a driving inclined surface that mates with the mating inclined surface. When the operating member is operated and moves relative to the seat in the second direction, the driving inclined surface applies a force to the mating inclined surface to drive the locking member to move from the locked position to the unlocked position in the first direction.

[0007] In one embodiment, the locking member includes a first locking member and a second locking member that are retractable relative to the seat along the first direction. The connecting member is provided with a first locking hole and a second locking hole that respectively cooperate with the first locking member and the second locking member. The first locking member and the second locking member are respectively provided with a first mating inclined surface and a second mating inclined surface. The operating member is correspondingly provided with a first driving inclined surface and a second driving inclined surface. When the operating member is operated and moves relative to the seat along the second direction, the first driving inclined surface and the second driving inclined surface apply forces to the first mating inclined surface and the second mating inclined surface respectively to drive the first locking member and the second locking member to disengage from the first locking hole and the second locking hole respectively.

[0008] In one embodiment, the locking device further includes a locking elastic element disposed between the first locking member and the second locking member and configured to move the first locking member and the second locking member away from each other to a locked position and remain in the locked position.

[0009] In one embodiment, the connector is provided with a locking hole, and the locking member can extend into the locking hole and exit from the locking hole along the first direction to move between the locked position and the unlocked position. The connector is also provided with a guide ramp near the locking hole. When the high chair is switching between the unfolded state and the folded state, the guide ramp guides the locking member to extend into and exit the locking hole.

[0010] In one embodiment, the connector is provided with a connector connection hole, and the seat is provided with a connecting shaft that mates with the connector connection hole. Through the mate between the connector connection hole and the connecting shaft, the connector can be rotatably connected to the seat. The connector connection hole is located in front of the locking hole, and the guide slope is located above the locking hole.

[0011] In one embodiment, the upper end of the connector is provided with an abutting upper edge, and when the bar chair is in the unfolded state, the abutting upper edge abuts against the lower part of the seat.

[0012] In one embodiment, the high chair includes two front legs, and a foot pedal is detachably connected between the two front legs. The foot pedal includes a foot pedal body extending laterally between the two front legs, and connecting ears protruding from both ends of the foot pedal body in a direction perpendicular to the extending direction of the foot pedal body. The connecting ears are connected to the front legs via a foot pedal connecting member, so that the foot pedal body can be flipped up and down.

[0013] In one embodiment, the high chair further includes a tray detachably connected to the seat, and the foot pedal body has two end faces along the lateral width direction respectively provided with foot pedal engagement holes, which can engage with the tray boss on the tray so that the tray can be stored in the foot pedal.

[0014] In one embodiment, the foot pedal connecting member includes: a foot pedal locking hole disposed on one of the front support leg connecting seat and the connecting ear, and a foot pedal locking member disposed on the other, the foot pedal locking member being movable or deformable along the extension direction of the foot pedal body to engage and disengage with the foot pedal locking hole.

[0015] In one embodiment, one of the front support leg connecting seat and the connecting ear is provided with a limiting block, and the other is provided with a limiting groove. The limiting groove is provided with at least one lateral opening so that the limiting groove can engage with the limiting block, thereby limiting the foot pedal in at least one direction.

[0016] In one embodiment, the connector is provided with a connector locking rod, and the locking member is provided with a locking part. The connector locking rod and the locking part are configured such that when the locking member is in the locked position, the locking part can limit the connector locking rod so that the connector cannot rotate to the closed position. When the locking member is in the unlocked position, the locking part no longer limits the connector locking rod so that the connector can rotate to the closed position.

[0017] In one embodiment, the high chair further includes an operating member movably connected to the connector, the operating member, when operated, causing the locking member to move between the locked position and the unlocked position.

[0018] In one embodiment, a retractable elastic element is provided between the connector and the seat, the retractable elastic element being configured to tend to rotate the connector relative to the seat toward a retracted position or an unfolded position.

[0019] In one embodiment, the seat is provided with a connecting shaft, and the connector is rotatably connected to the connecting shaft, so that the connector is rotatably connected to the seat, and the retractable elastic member is a torsion spring sleeved on the connecting shaft.

[0020] In one embodiment, the first end of the torsion spring is connected to the connecting portion of the connector, and the second end of the torsion spring is connected to the seat.

[0021] In one embodiment, the connector is provided with a locking hole that cooperates with the locking member, and the seat is also provided with a movable limiting member. The limiting member can extend and retract relative to the seat along the first direction with the locking member. When the locking member does not cooperate with the locking hole and the limiting member is in the extended state, the limiting member can prevent the connector from rotating from the folded position to the unfolded position or prevent the connector from rotating from the unfolded position to the folded position.

[0022] In one embodiment, the connector is provided with a connector limiting hole that cooperates with the limiting member. When the locking member cooperates with the locking hole, the limiting member can extend into the connector limiting hole.

[0023] In one embodiment, the connector is provided with a locking hole that cooperates with the locking member. When the locking member is not engaged with the locking hole and is in the extended state, the locking member can prevent the connector from rotating from the retracted position to the extended position or prevent the connector from rotating from the extended position to the retracted position.

[0024] Another aspect of this disclosure provides a locking device, which includes a locking member movably connected to an object to be locked and capable of moving between a locked position and an unlocked position along a first direction.

[0025] The beneficial effect of this disclosure is that, when the high chair is not in use, the rear support legs can be folded relative to the seat to save storage space, and the high chair can stand up after being folded, making it convenient to store.

[0026] The foregoing and other objects, features, aspects and advantages of this disclosure will become more apparent from the following detailed description of this disclosure in conjunction with the drawings.

Implementation Method

[0086] This disclosure will now be described in detail with reference to the drawings.

[0087] Figures 1 to 4 illustrate one embodiment of a high chair 1 according to one aspect of the present disclosure. It should be understood that although the high chair 1 shown in the figures is a children's chair, the high chair 1 according to the present disclosure can also be an adult chair, such as a high chair for a bar.

[0088] For ease of description, as shown in Figures 1 and 4, the direction a child faces while sitting in the high chair 1 is defined as "front," and the direction they face away from is defined as "back." The direction perpendicular to the front-back direction on the horizontal plane is defined as the left-right direction or the lateral width direction of the seat.

[0089] As shown in Figures 1 to 4, the high chair 1 may include a seat 100 and legs connected to the seat 100. The legs are pivotable relative to the seat 100 to allow the high chair 1 to unfold and fold. Specifically, the legs may include a front leg 200 and a rear leg 300. In some embodiments, the front leg 200 is fixedly connected to the seat 100, while the rear leg 300 is pivotally connected to the seat 100 to enable the high chair 1 to unfold and fold. Of course, it is also possible that the front leg 200 is pivotally connected to the seat 100, while the rear leg 300 is fixedly connected to the seat 100; and that the front leg 200 is pivotally connected to the seat 100, and the rear leg 300 is also pivotally connected to the seat 100. This application is not limited thereto. Alternatively, the support legs can include a left support leg and a right support leg, one of which is fixedly connected to the seat 100, while the other is pivotally connected to the seat 100, which can also realize the unfolding and folding of the high chair 1.

[0090] In some embodiments, as shown in Figures 1 to 4, the high chair 1 includes two front legs 200 and two rear legs 300. However, it should be understood that the high chair 1 may 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.

[0091] To extend the usage time of the high chair 1, the front support leg 200 of the high chair 1 according to this disclosure may include an upper front support leg 210 and a lower front support leg 220 detachably connected to each other, and the rear support leg 300 may include an upper rear support leg 310 and a lower rear support leg 320 detachably connected to each other. Thus, the high chair 1 has three usage modes. Specifically, when the upper front support leg 210 and the lower front support leg 220 connected together constitute the front support leg 200, and the upper rear support leg 310 and the lower rear support leg 320 connected together constitute the rear support leg 300, and when the tray 700 and the armrest 600, which will be described later, are connected to the seat 100, the high chair 1 is in a first usage mode with a higher height, for example, suitable for use as a dining chair when the child is small. When the upper front leg section 210 and the lower front leg section 220 are connected together to form the front leg 200, and the upper rear leg section 310 and the lower rear leg section 320 are connected together to form the rear leg 300, and the tray 700 and armrest 600 are removed from the seat 100, the high chair 1 is in a second usage mode with a higher height, for example, suitable for use as a dining chair when the child is older. When the upper front leg section 210 and the lower front leg section 220 are separated so that only the upper front leg section 210 forms the front leg 200, and the upper rear leg section 310 and the lower rear leg section 320 are separated so that only the upper rear leg section 310 forms the rear leg 300, the high chair 1 is in a third usage mode with a lower height, for example, suitable for use as a play chair when the child is older.

[0092] In order to facilitate the storage of the high chair 1, the high chair 1 needs to be foldable. In some embodiments, the front support leg 200 is fixedly connected to the seat 100, and the rear support leg 300 is connected to a connector 400. The connector 400 is rotatably connected to the seat 100, thereby causing the rear support leg 300 to rotate relative to the seat 100 to fold and unfold.

[0093] In some embodiments, as shown in FIG10, the connector 400 is rotatably connected to the seat 100 via a connecting shaft 110. Specifically, the connector 400 is connected to one end of the rear support leg 300, and the connector 400 is provided with a connector connection hole 420. Correspondingly, the bottom of the seat 100 is provided with a connecting shaft 110. The connecting shaft 110 can pass through a through hole on the bottom of the seat 100 and be connected to the seat 100. In one embodiment, the connecting shaft 110 can be disposed on the fixing seat 510 of the locking device 500, which will be described later. By inserting the connecting shaft 110 into the connector connection hole 420 on the connector 400, the connector 400 and the rear support leg 300 connected thereto can rotate relative to the seat 100.

[0094] As shown in FIG. 10, when the rear support leg 300 is pivotally connected to the seat 100 via the connector 400, the connector connection hole 420 is located in front of the locking hole 410, which will be described later, to facilitate locking the rear support leg 300 in the extended position. It should be understood that when the front support leg 200 is pivotally connected to the seat 100 via the connector 400, the connector connection hole 420 may be located behind the locking hole 410 to facilitate locking the front support leg 200 in the extended position.

[0095] Of course, the connector 400 can also be rotatably connected to the seat 100 in other ways. For example, the connector 400 is provided with a connecting shaft, and the bottom of the seat 100 is provided with a connecting hole for the connecting shaft to pass through. Alternatively, the connector 400 is provided with a cylindrical protrusion, and the bottom of the seat 100 is provided with a cylindrical recess, which accommodates the protrusion and allows the protrusion to rotate therein, thereby achieving the rotatable connection of the connector 400 to the seat 100 through the cooperation of the protrusion and the recess.

[0096] Since the rear support leg 300 can rotate relative to the seat 100 via the connector 400, when the rear support leg 300 rotates relative to the seat 100 to a position away from the front support leg 200, the high chair 1 is in an unfolded use state, as shown in Figure 1; when the rear support leg 300 rotates relative to the seat 100 to a position close to the front support leg 200, the high chair 1 is in a folded storage state, as shown in Figure 6, thereby achieving the purpose of saving storage space. In addition, the high chair 1 can stand up after being folded, making it convenient for storage.

[0097] Of course, this disclosure is not limited thereto. In other embodiments, the rear support leg 300 can be fixedly connected to the seat 100, while the front support leg 200 can be rotatably connected to the seat 100 via the connector 400. This embodiment can also achieve the purpose of saving storage space.

[0098] In order to control the rotation of the connector 400 relative to the seat 100, the high chair 1 according to the present disclosure may also include a locking device 500 disposed on the seat 100 and operable to allow or prevent the connector 400 from rotating relative to the seat 100.

[0099] Figures 8 to 10 illustrate one embodiment of the locking device 500 according to the present disclosure.

[0100] In this embodiment, the locking device 500 includes a locking member 520, which is movably connected to the seat 100 and can move relative to the connecting member 400 along a first direction D1 (see Figures 8 and 9) between a locked position and an unlocked position. The first direction D1 is, for example, the lateral width direction of the seat 100, that is, the locking member 520 can move along the lateral width direction of the seat 100. As shown in Figure 8, when the locking member 520 is in the locked 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 support leg 300 relative to the seat 100, so as to keep the high chair 1 in an unfolded or folded state. As shown in Figure 9, when the locking member 520 is in the unlocked position, it exits the locking hole 410 on the connecting member 400, thereby allowing the connecting member 400 to rotate the rear support leg 300 relative to the seat 100, so that the high chair 1 can switch between an unfolded state and a folded state. In this embodiment, the locking hole 410 on the connector 400 is located behind the connecting hole 420, thereby facilitating the folding and rearward extension of the rear support leg 300. In other embodiments where the front support leg 200 can pivotally fold, the locking hole 410 may be located in front of the connecting hole 420, thereby facilitating the folding and forward extension of the front support leg 200.

[0101] Although only one set of locking holes 410 is shown in the embodiments shown in Figures 8 to 10 for holding the high chair 1 in the unfolded state when the locking member 520 is inserted into the locking holes 410, in other embodiments, multiple sets of locking holes 410 may be provided on the connector 400 so that when the locking member 520 is inserted into different sets of locking holes 410, the rear support leg 300 can be held in multiple rotational positions relative to the seat 100, thereby holding the high chair 1 in a folded state, an unfolded state, and an intermediate state between the folded and unfolded states.

[0102] When the bar chair 1 is in the folded state, as shown in Figure 6, the bar chair 1 can stand up after being folded, thus making it convenient to store.

[0103] In some embodiments, as shown in FIG10, the locking device 500 may further include a fixing seat 510, which is fixedly connected to the seat 100, and the locking member 520 is movably connected to the fixing seat 510. Generally, the fixing seat 510 is located at the bottom or back of the seat 100. Of course, the fixing seat 510 may be positioned at other positions on the seat 100 as needed. In some embodiments, the fixing seat 510 may also be integrally formed with the seat 100, that is, the fixing seat 510 connected to the seat 100 may not be additionally provided.

[0104] To facilitate the operation and movement of the locking member 520, in some embodiments, as shown in Figures 8 to 10, the locking device 500 may further include an operating member 530, which is movably connected to the fixed base 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 Figures 8 and 9), thereby causing the locking member 520 to move along a first direction D1 between a locked position and an unlocked position. In some embodiments, the first direction D1 is the lateral width direction of the seat, and the second direction D2 is the height direction of the seat, that is, the longitudinal direction perpendicular to the horizontal plane. Of course, the second direction D2 may not be perpendicular to the horizontal plane, but may be at a certain angle to it, which can also achieve the function of the operating member 530 driving the locking member 520 to move according to the present disclosure.

[0105] Figures 11 and 12 illustrate one embodiment of the locking member 520 and the operating member 530 according to the present disclosure. As shown in Figures 11 and 12, the locking member 520 includes a first locking member 521 and a second locking member 522 that are movable relative to each other. The first locking member 521 and the second locking member 522 are respectively provided with extensions extending in the relative movement direction, which are respectively able to be inserted into corresponding locking holes 410. In this embodiment, the first locking member 521 and the second locking member 522 adopt a sleeve structure that is nested together. It should be understood that the first locking member 521 and the second locking member 522 can adopt other mating structures, for example, one of them is provided with a guide groove and the other with a guide rail, and the relative movement of the two is achieved through the mating structure of the guide groove and the guide rail.

[0106] 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 mating inclined surface 521A (see Figure 12), and the second locking member 522 is provided with a second mating inclined surface 522A (see Figure 12). Correspondingly, the operating member 530 is provided with a first driving inclined surface 531 (see Figure 12) that abuts against the first mating inclined surface 521A, and a second driving inclined surface 532 (see Figure 11) that abuts against the second mating inclined surface (522A).

[0107] In the embodiments shown in Figures 11 and 12, the operating member 530 may be a button for easy user operation. When the operating member 530 is operated (i.e., the user applies a pressing force to the operating member 530) and moves (e.g., moves upward), the first driving ramp 531 and the second driving ramp 532 apply forces to the first mating ramp 521A on the first locking member 521 and the second mating ramp 522A on the second locking member 522, respectively, to drive the first locking member 521 and the second locking member 522 to move closer to each other and to the unlocked position. Then, as shown in Figure 9, the locking member 520 disengages from the locking hole 410 on the connector 400, thereby allowing the connector 400 to drive the support leg to rotate relative to the seat 100.

[0108] As shown in FIG12, the locking device 500 may further include a locking elastic element 540, which may be disposed, for example, between the first locking element 521 and the second locking element 522, and is configured to tend to move the first locking element 521 and the second locking element 522 away from each other to a locked position and remain in that locked position, thereby preventing the connecting member 400 from rotating relative to the seat portion 100. Thus, when the operating member 530 is not operated (i.e., the user does not apply force to the operating member 530), the locking elastic element 540 will drive the first locking element 521 and the second locking element 522 away from each other. In this process, the first mating inclined surface 521A on the first locking element 521 and the second mating inclined surface 522A on the second locking element 522 will apply forces to the first driving inclined surface 531 and the second driving inclined surface 532 of the operating member 530, respectively, thereby driving the operating member 530 to the initial position in preparation for the next release of the locking device 500.

[0109] The locking elastic element 540 can be an elastic element such as a spring, a pneumatic rod or a hydraulic rod.

[0110] When the user unfolds the high chair 1, the high chair 1 may be in a partially unfolded state. In one embodiment, preferably, in order to prevent the high chair 1 from being in such a partially unfolded state, a folding limiting mechanism can also be provided inside the high chair 1, so that the high chair 1 can only switch between the fully unfolded state shown in FIG. 42 and the folded state shown in FIG. 43, so as to avoid the occurrence of a partially unfolded state.

[0111] As shown in Figures 45 to 47, the high chair 1 equipped with the retraction limiting mechanism is basically the same as the high chair 1 shown in Figures 8 to 12, except that the retraction limiting mechanism is added.

[0112] In one embodiment, the folding limiting mechanism according to this disclosure may include a folding elastic member 111 disposed between the connector 400 and the seat 100, and tending to rotate the connector 400 relative to the seat 100 toward a folded position. In other embodiments, the folding elastic member 111 is also disposed between the connector 400 and the seat 100, and tending to rotate the connector 400 relative to the seat 100 toward an unfolded position.

[0113] In the embodiments shown in Figures 48 to 50 and Figures 53 to 55, the retraction elastic element 111 is a torsion spring 111 sleeved on the connecting shaft 110. Of course, the retraction elastic element 111 according to this disclosure can also be other elastic elements such as tension springs or tension rods, as long as they can tend to rotate the connecting member 400 relative to the seat 100 toward the retracted position.

[0114] As shown in Figure 53, the first end 111A of the torsion spring 111 is connected to the connecting part 490 of the connector 400, and the second end 111B of the torsion spring 111 is connected to the seat 100.

[0115] In one embodiment, the first end 111A of the torsion spring 111 is connected to the torsion spring fixing protrusion 491 on the connecting portion 490 of the connector 400 (see FIG. 53). The second end 111B of the torsion spring 111 presses against the fixing post 172 connected in the mounting groove 170 of the seat 100 between the fixing post 172 and the inner sidewall 171 (see FIG. 55).

[0116] Since the retractable elastic member 111 tends to cause the connector 400 to rotate relative to the seat 100 toward the retracted position, once the high chair 1 is not in the unfolded state, the retractable elastic member 111 will drive the high chair 1 into the retracted state, thus avoiding the high chair 1 being in an incompletely unfolded state between the unfolded state and the retracted state.

[0117] In one embodiment, preferably, the retraction limiting mechanism may further include a limiting member movably disposed on the seat. The limiting member may take the form of a limiting rod or a limiting element protrusion, etc.

[0118] In the embodiments shown in Figures 47 to 52, the limiting members include a first limiting member 521B and a second limiting member 522B respectively disposed on the first locking member 521 and the second locking member 522, which are substantially parallel to the first locking portion 521C and the second locking portion 522C, respectively. They are respectively capable of extending and retracting relative to the seat 100 along a first direction D1 (see Figure 47) with the first locking member 521 and the second locking member 522, and can prevent the connecting member 400 from rotating from the folded position to the unfolded position when extended. In other embodiments, the first limiting member 521B and the second limiting member 522B can be configured to prevent the connecting member 400 from rotating from the unfolded position to the folded position. Furthermore, it is understood that the number of limiting members is not limited to two. The limiting members may include only one limiting member disposed on either the first locking member 521 or the second locking member 522, or may include multiple limiting members disposed on the first locking member 521 and the second locking member 522.

[0119] In an alternative embodiment, a separate limiting member may not be provided. At least one of the first locking part 521C and the second locking part 522C may be used to prevent the connector from rotating from the closed position to the unfolded position, as shown in FIG51B.

[0120] In this case, taking the second locking part 522C shown in FIG51B as an example, when viewed in the left-right direction, the second locking part 522C presents an obliquely extending elongated structure. In particular, in the front-to-back direction, the second locking part 522C extends obliquely from bottom to top. The dimensions of the second locking part 522C are configured such that when the connecting member 400 and the rear support leg 300 are in the retracted position and the second locking part 522C is in the extended position, the second locking part 522C can prevent the connecting member 400 from rotating from the retracted position to the extended position.

[0121] Of course, this disclosure is not limited thereto. The second locking part 522C may also take the form of a cylindrical shape or other suitable structures. In addition, the structure of the first locking part 521C may be the same as or different from that of the second locking part 522C.

[0122] When the high chair 1 is in the folded state, the second limiting element 522B is in the extended state along with the second locking element 522 (as shown in Figure 51A), and the first limiting element 521B is also in the extended state along with the first locking element 521 (not shown). Therefore, the second limiting element 522B and the first limiting element 521B will block the upper edge of the connector 400, so that the connector 400 cannot rotate toward the folded position.

[0123] When the user prepares to switch the high chair 1 to the unfolded state, a force can be applied to the operating member 530. The operating member 530 then drives the second locking member 522 and the first locking member 521 to move and retract, causing the second limiting member 522B following the second locking member 522 and the first limiting member 521B following the first locking member 521 to also retract. As a result, the connecting member 400 is no longer blocked by the second limiting member 522B and the first limiting member 521B and can rotate toward the unfolded position.

[0124] The connector 400 is provided with connector limiting holes 480 that respectively cooperate with the second limiting member 522B and the first limiting member 521B. When the connector 400 is rotated to the unfolded position, as shown in FIG52, the first locking part 521C and the second locking part 522C can extend and be inserted into the corresponding locking holes 410 on the connector 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 connector limiting holes 480 on the connector 400 to keep the high chair 1 in the unfolded state. In other embodiments, alternatively, when the connector 400 is rotated to the unfolded position, the locking part extends into the corresponding locking hole, and the limiting member extends into the corresponding connector limiting hole.

[0125] In the embodiment shown in FIG. 51B, which does not have a separate limiting member, it is naturally unnecessary to provide a separate connector limiting hole. In this case, the locking hole 410 can be used as a connector limiting hole. When the second locking part 522C is inserted into the corresponding locking hole 410 on the connector 400, the high chair 1 can be kept in the unfolded state.

[0126] When the retractable elastic member 111 is provided, if the second locking member 522 and the first locking member 521 are blocked by the connector and do not extend and are not inserted into the corresponding locking hole 410 on the connector 400 (correspondingly, the second limiting member 522B and the first limiting member 521B are not inserted into the corresponding connector limiting hole 480 on the connector 400), the connector 400 will rotate toward the retracted position under the elastic force of the retractable elastic member 111, thereby preventing the high chair 1 from being in a partially unfolded state.

[0127] It should be understood that the locking device 500 according to this disclosure is not limited thereto.

[0128] In other embodiments, the locking member 520 and the operating member 530 may adopt other mating structures. For example, the operating member 530 may be a knob with a gear at one end, and the locking member 520 may be a rack that engages 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 may not have an operating member 530, and the locking member 520 may have a part that the user can access, thereby allowing the user to directly access and move the locking member 520. In other embodiments, the locking device 500 may not even need to use the method of inserting or withdrawing the locking member 520 into or out of the locking hole 410 on the connector 400 to prevent or allow the connector 400 to rotate relative to the seat 100, but may adopt other methods. For example, one of the connector 400 and the seat 100 is provided with a hook and the other is provided with a hanging ring. When the connector 400 is rotated to a suitable position relative to the seat 100, the relative rotation between the two can be prevented or allowed by hooking or disengaging the hook from the hanging ring.

[0129] In some embodiments, to facilitate the user's unfolding of the high chair 1, as shown in FIG10, the connector 400 may be provided with a guide slope 430. The guide slope 430 extends from the upper end of the connector 400 along a direction inclined to the upper end to the locking hole 410 or to the vicinity of the locking hole 410, 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 its legs and connector 400 unfold, the locking member 520 is compressed by the guide slope 430 and slides along the guide slope 430 relative to the connector 400 to the locking hole 410. Subsequently, the locking member 520 extends under the elastic force of the locking elastic member 540 and inserts into the locking hole 410. Thus, the user only needs to pull the legs to complete the unfolding of the high chair 1 without operating the operating member 530.

[0130] In some embodiments, as shown in Figures 10, 24, and 26, the upper end of the connector 400 may also be provided with an abutting upper edge 440. When the connector 400 and its connected rear support leg 300 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 connector 400 and its connected rear support leg 300 toward the unfolded position; on the other hand, the abutting upper edge 440 of the connector 400 is supported by the bottom of the seat 100, which can improve the stability of the high chair 1 in the unfolded state.

[0131] In some embodiments, as shown in Figures 10, 24, and 26, the bottom of the seat 100 may be provided with a limiting wall 130 extending outward from the bottom. The limiting wall 130 is configured such that when the connecting member 400 and its connected rear support leg 300 rotate to the unfolded position, the limiting wall 130 abuts against the connecting member 400 and restricts the connecting member 400 from continuing to rotate in the same direction (see Figure 24). Therefore, the limiting wall 130 can also limit the rotation angle of the connecting member 400 and its connected rear support leg 300 toward the unfolded position, and can make the connecting member 400 supported by the bottom of the seat 100, thereby improving the stability of the high chair 1 in the unfolded state.

[0132] In some embodiments, as shown in Figures 24 and 26, the bottom of the seat 100 may also be provided with a limiting element rib 140 and a guide rib 150. The limiting element rib 140 and the guide rib 150 extend outward from the bottom, and the guide rib 150 is located in front of the limiting element rib 140. The two form a space for the front edge 450 of the connector 400 to move therein. It is configured such that when the connector 400 and the rear support leg 300 connected thereto rotate to the unfolded position, the limiting rib 140 and the front edge 450 of the connector 400 are separated in the front-rear direction so that they do not interfere with each other (see Figure 24), and the front edge 450 of the connector is close to the guide rib 150; when the connector 400 and the rear support leg 300 connected thereto rotate to the folded position, the front edge 450 of the connector 400 abuts against the limiting rib 140 under the guidance of the guide rib 150 and restricts the connector 400 from continuing to rotate in the same direction (see Figure 26). Therefore, the limiting rib 140 can limit the rotation angle of the connector 400 and the rear support leg 300 connected thereto toward the folded position, and can improve the stability of the high chair 1 in the folded state.

[0133] In some embodiments, as shown in FIG27, a limiting middle portion 160 may be provided on the bottom of the seat 100, which is located between the two front edges 450 of the connector 400. Correspondingly, a connector limiting portion 460 is provided on the connector 400 below the limiting middle portion 160. When the connector 400 and the rear support leg 300 connected thereto rotate to the folded position, the limiting middle portion 160 abuts against the connector limiting portion 460 to restrict the connector 400 from continuing to rotate in the same direction, thereby limiting the rotation angle of the connector 400 and the rear support leg 300 connected thereto toward the folded position, and improving the stability of the high chair 1 in the folded state.

[0134] Figures 35 to 41 show a locking device 500I according to another embodiment of the present disclosure.

[0135] In this embodiment, as shown in FIG36, the locking device 500I includes a locking member 520I, which is movably connected to the seat 100 and is movable relative to the connecting member 400 along a third direction D3 (see FIG40) between a locked position and an unlocked position. As shown in FIG37, FIG38, FIG40 and FIG41, the locking member 520I is provided with a locking portion 523I. The third direction D3 is, for example, the fore-and-aft direction of the seat 100, that is, the locking member 520I is movable along the fore-and-aft direction of the seat 100. In one embodiment, the upper end face of the locking portion 523I extends along the third direction D3, that is, extends parallel to the horizontal plane.

[0136] Correspondingly, as shown in Figures 39 to 41, the connector 400I is provided with a connector locking lever 470I. In order to control the rotation of the connector 400I relative to the seat 100, the connector locking lever 470I and the locking part 523I are configured such that when the locking part 520I moves to the locking position, as shown in Figure 40, in the unfolded state of the seat 100, the upper end of the locking part 523I can block the connector locking lever 470I, so that the connector 400I and the rear support leg 300 connected thereto cannot rotate to the folded position relative to the seat 100 within a certain range or a certain limit; when the locking part 520I moves to the unlocking position, as shown in Figure 41, in the unfolded state of the seat 100, the locking part 523I no longer blocks the connector locking lever 470I, so that the connector 400I and the rear support leg 300 connected thereto can rotate to the folded position relative to the seat 100 around the connecting shaft 110 (see Figure 38).

[0137] Specifically, in the unfolded state of the seat 100, the upper end face of the locking part 523I can tightly abut against the connecting locking rod 470I, so that the upper end face of the locking part 523I can completely block the connecting locking rod 470I from rotating. Alternatively, in the unfolded state of the seat 100, the upper end face of the locking part 523I can also have a certain gap with the connecting locking rod 470I, so that the connecting locking rod 470I has a small amount of rotation space, and after it rotates a small angle toward the folded position, it is blocked by the upper end face of the locking part 523I and cannot continue to rotate.

[0138] In this disclosure, when the high chair 1 is in the folded state, the connector 400 and the rear support leg 300 are in the folded position accordingly, and when the high chair 1 is in the unfolded state, the connector 400 and the rear support leg 300 are in the unfolded position accordingly.

[0139] In one embodiment, the lower end face 524I of the locking part 523I is an inclined surface. Specifically, along the front-to-back direction, the lower end face 524I of the locking part 523I is an inclined surface extending upwards. Therefore, in the folded state of the seat 100, when the rear support leg 300 is subjected to a force and moves toward the unfolded position, the connecting locking rod 470I abuts against the inclined lower end face 524I of the locking part 523I and causes the locking member 520I to move toward the unlocked position along the third direction D3, thereby allowing the connecting locking rod 470I to continue rotating toward the unfolded position, and causing the connecting locking rod 470I, the connecting member 400I and the rear support leg 300 connected thereto to eventually rotate to the unfolded position without applying an additional forward force to the locking member 520I.

[0140] Understandably, in other embodiments, the lower end face 524I of the locking part 523I may extend along a third direction D3, that is, extend parallel to the horizontal plane. In this case, when the rear support leg 300 is in the retracted position and is subjected to force to rotate backward, the lower end face 524I of the locking part 523I will block the movement of the connecting locking rod 470I, thereby blocking the rotation of the rear support leg 300, so that the rear support leg 300 cannot rotate to the unfolded position. Therefore, when the rear support leg 300 is in the retracted position and needs to be unfolded, a forward force needs to be applied to the locking member 520I so that the locking member 520I reaches the unlocked position before the rear support leg 300 can rotate backward and unfold.

[0141] In one embodiment, in order to facilitate the operation of the locking member 520I to move it between the locked position and the unlocked position, in the embodiments shown in FIG39 to FIG41, the locking device 500I may further include an operating member 530I, which is movably connected to the connector 400I along the third direction D3 and is capable of driving the locking member 520I to move between the locked position and the unlocked position when operated.

[0142] As shown in FIG40, the operating member sidewall 533I of the operating member 530I can abut against the right end face 525I of the locking part 523I of the locking member 520I, so that when the operating member 530I is pressed inward along the third direction D3, the operating member 530I pushes the locking member 520I and moves it from the locked position to the unlocked position.

[0143] In this embodiment, the lower end face 524I of the locking member 520I is an inclined surface, and the end of the operating member 530I abuts against the inclined surface 524I. In other embodiments, additionally, the lower end face 524I of the locking member 520I is an inclined surface and may include a recess whose shape matches the shape of the end of the operating member 530I (see the dashed lines in Figures 40 and 41) so that the operating member 530I can better push the locking member 520I to move.

[0144] On the other hand, the operating member 530I can also be operated to retract outward along the third direction D3 to the initial position. The operating member 530I and the locking member 520I can be connected through a flexible intermediate member (not shown), so that when the operating member 530I is retracted outward along the third direction D3, the operating member 530I drives the locking member 520I to move from the unlocked position to the locked position.

[0145] In another embodiment, in order to facilitate user operation, a second locking elastic member (not shown) can be provided between the bottom of the seat 100 and the locking member 520I. The second locking elastic member is configured to tend to move the locking member 520I from the unlocked position to the locked position, and in the process drive the operating member 530I to return to the initial position along the third direction D3 towards the outside.

[0146] As shown in Figure 45, a front foot pad 201 may be provided at the bottom of the front support leg 200, and a rear foot pad 201 may be provided at the bottom of the rear support leg 200, in order 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 may be provided with a support inclined surface, so that the high chair 1 can be supported more stably.

[0147] In the embodiment shown in FIG. 14, the high chair 1 may further include an armrest 600 detachably connected to the seat 100. When a smaller child (e.g., an infant older than 6 months) sits in the high chair 1, as shown in FIG. 1, the seat 100 may have an armrest 600 connected to it to protect the smaller child from accidental detachment from the seat 100, and to attach items such as a tray 700 (described later) to the armrest 600. When an older child (e.g., a child older than 3 years) sits in the high chair 1, as shown in FIG. 2, the seat 100 may not need to have an armrest 600 connected, giving the child greater freedom.

[0148] The armrest 600 may include an armrest connector 610, which can engage with the seat connection portion 120 on the seat 100. In the embodiment shown in FIG15, the armrest connector 610 is in the form of a cover at both ends, which can cooperate with the protruding seat connection portions 120 on both sides of the seat 100 (see FIG2 and FIG16) so that the armrest 600 can be easily and quickly connected to the seat 100.

[0149] In some embodiments, to enhance the connection between the armrest 600 and the seat 100, as shown in FIG15, the armrest connecting portion 610 may be provided with an armrest connecting piece 611, which can be inserted into the seat connecting hole 121 on the seat connecting portion 120 (see FIG16). In the embodiment shown in FIG15, the armrest connecting piece 611 is located inside the cover-shaped armrest connecting portion 610 and extends downward, and the seat connecting hole 121 is formed through the protruding seat connecting portion 120 (see FIG16) and can be inserted into the armrest connecting piece 611.

[0150] Further, as shown in FIG15, the armrest connecting piece 611 of the armrest connecting portion 610 may be provided with a connecting piece engagement hole 612. Correspondingly, as shown in FIG16, the inner wall of the seat connecting hole 121 of the seat connecting portion 120 is provided with a connecting hole finger 122. The connecting hole finger 122 is elastic and extends outward from the inner wall of the seat connecting hole 121 in a cantilever form. As shown in FIG18, since the connecting hole finger 122 is elastic and has a tapered structure at its 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. However, once the connecting piece engagement 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. By engaging the connecting plate engagement hole 612 with the connecting hole finger 122, the armrest 600 can be effectively prevented from accidentally detaching from the seat 100, thus ensuring the safety of children sitting in the seat 100.

[0151] Furthermore, as shown in FIG18, the interior of the seat connecting portion 120 is hollow and has an opening at the bottom, so that the armrest connecting piece 611 inserted into the seat connecting hole 121 can be exposed at the bottom of the seat connecting portion 120. Thus, the user can contact the armrest connecting piece 611 through the lower opening of the seat connecting portion 120 and apply 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 subsequently allowing the armrest 600 to be detached from the seat 100.

[0152] The armrest connecting piece 611 can be integrally formed with the armrest joint 610, or it can be formed separately.

[0153] In another embodiment of the handrail 600 shown in FIG. 56, the handrail connecting piece 611, on which the connecting piece engagement hole 612 is formed, is a separately molded single component, which can be fixed to the handrail engagement portion 610 by connecting piece fasteners 613 such as screws or rivets. In this way, once the elasticity of the handrail connecting piece 611 weakens due to long-term use, the handrail connecting piece 611 can be replaced, thereby avoiding the need to replace the entire handrail 600.

[0154] Correspondingly, as shown in FIG58, a connecting hole engagement piece 124 extends downward from the edge of the seat connecting hole 121. Engagement finger 125 is formed on the connecting hole engagement piece 124. The engagement finger 125 is configured to engage with the connecting hole engagement piece 612 on the armrest connecting piece 611 (see FIG59), thereby preventing the armrest connecting piece 611 from exiting the seat connecting hole 121, so as to avoid the armrest 600 from accidentally detaching from the seat 100.

[0155] In order to further strengthen the connection between the armrest 600 and the seat 100, the armrest connecting part 610 may also be provided with a connecting piece limiting hook 614, as shown in FIG56. It can be inserted into the seat limiting hole 123 on the seat connecting part 120 (see FIG57 and FIG58) and form an inverted engagement with the seat 100, thereby further fixing the armrest 600 to the seat 100.

[0156] In the embodiment shown in FIG1, the high chair 1 may further include a tray 700, which is detachably connected to the armrest 600. The tray 700 can greatly expand the function of the high chair 1, which can not only be used as a child's plate to place children's bowls or food, but also as a child's worktable to place children's toys.

[0157] To ensure that the tray 700 remains fixed relative to the armrest 600 after being installed on it, as shown in FIG13, the tray 700 is provided with a tray engaging block 710 that can move between an engaged position and a disengaged position along the lateral width direction of the seat 100. The tray engaging block 710 also includes a tray engaging protrusion 711 that protrudes inward along the lateral width direction of the seat 100. Correspondingly, as shown in FIG14, there is an armrest recess 620 on the armrest 600. When the tray engaging block 710 moves to the engaged position, the tray engaging protrusion 711 on the tray engaging block 710 engages with the armrest recess 620 on the armrest 600. In some embodiments, multiple armrest recesses 620 may be provided on the armrest 600, and the tray engaging block 710 may selectively engage with different armrest recesses 620, thereby adjusting the relative position of the tray 700 and the seat 100 to better accommodate children of different body sizes.

[0158] Further, as shown in FIG18, a tray elastic member 720 may be provided on the tray 700, which is configured to tend to move the tray engaging block 710 to the engaging position. This ensures the relative fixation between the tray 700 and the handrail 600.

[0159] Optionally, the surface of the tray engaging protrusion 711 is inclined. When the tray 700 needs to be installed onto the armrest 600, the tray 700 is aligned with the armrest 600 and the tray engaging protrusion 711 abuts against the upper end of the armrest 600, applying a downward force to the tray 700. Due to the inclined surface, the tray engaging protrusion 711 will move outward along the lateral width direction, causing the tray 700 to continue moving downward. After the tray 700 moves downward into place, the tray engaging protrusion 711 extends into the armrest recess 620 under the action of the tray elastic member 720, thereby completing the engagement between the tray 700 and the armrest 600. When the tray 700 needs to be removed from the armrest 600, the user can operate the tray engaging block 710 to move to the disengaged position, disengaging the tray engaging protrusion 711 from the armrest recess 620, thereby releasing the relative fixation between the tray 700 and the armrest 600.

[0160] In some embodiments, the high chair 1 may include two front legs 200, with a footrest 800 detachably connected between the two front legs 200 for a child to step on, thereby increasing the child's riding comfort.

[0161] As shown in Figures 19 and 20, the foot pedal 800 according to this disclosure may include a foot pedal body 810 and connecting ears 820. The foot pedal body 810 extends along the lateral width of the seat 100 between the two front support legs 200, forming the main body of the foot pedal 800. The connecting ears 820 protrude from both ends of the foot pedal body 810 in a direction perpendicular to the extending direction of the foot pedal body 810.

[0162] The design of the connecting ear 820 extends the effective usage time of the footrest 800. When the connecting ear 820 is connected to the front support leg 200 via the footrest connecting member 830 (which is, for example, a connecting bolt), the footrest body 810 can be flipped up and down. Specifically, the footrest 800 has two installation positions. The first installation position is with the connecting ear 820 located below the footrest body 810, as shown in Figure 19. This makes the footrest body 810 closer to the seat 100, suitable for younger children. The second installation position is with the connecting ear 820 located above the footrest body 810, as shown in Figure 21. This makes the footrest body 810 farther away from the seat 100, suitable for older children. The footrest body 810 can be flipped up and down between the first and second installation positions to meet the needs of children at different stages.

[0163] In some embodiments, as shown in FIG22, preferably, a front support leg connecting seat 230 is provided on the front support leg 200 for connecting to the connecting ear 820 of the foot pedal 800, so as to connect the foot pedal 800 to the front support leg 200. The front support leg connecting seat 230 has a flat upper and wide lower design, so that the two front feet are kept parallel, which facilitates the installation of the foot pedal. In some embodiments, preferably, the surface of the connecting ear 820 that mates with the front support leg connecting seat 230, that is, the end face facing outward in the lateral width direction of the seat 100, extends longitudinally; while the surface of the front support leg connecting seat 230 that mates with the connecting ear 820, that is, the surface facing inward in the lateral width direction of the seat, extends longitudinally. In this way, the connection between the connecting ear 820 and the front support leg connecting seat 230 is more stable, and the up-and-down flipping of the connecting ear 820 is smoother, which facilitates the switching of usage modes. In some embodiments, the outer end face of the connecting ear 820 is provided with a square protrusion 821 (see FIG. 20), and the inner side of the front support leg connecting seat 230 is provided with a square recess 231 (see FIG. 22). The two cooperate to ensure that after the foot pedal 800 is installed, the foot pedal body 810 will not accidentally flip between the first installation position and the second installation position.

[0164] The front outrigger connecting seat 230 can be fixed to the front outrigger 200 by means of fasteners such as screws, as shown in Figure 33.

[0165] Figures 28 to 34 illustrate another embodiment of the foot pedal 800 according to the present disclosure. In this embodiment, the structure of the connecting ear 820 of the foot pedal 800 and the connection structure between the foot pedal 800 and the front support leg 200 are different from those in the previous embodiments, as described in detail below.

[0166] In this embodiment, as shown in Figures 28 to 30 and Figures 33 and 34, the foot pedal connecting member 830 may include a foot pedal locking member 831 disposed on the front support leg connecting seat 230. It is movably disposed on the front support leg connecting seat 230 and can extend and retract along the extension direction of the foot pedal body 810.

[0167] In the embodiment shown in FIG33, a resetting elastic element 832 may be provided on the inner side of the foot pedal locking member 831, which tends to cause the foot pedal locking member 831 to extend along the extending direction of the foot pedal body 810. The resetting elastic element 832 may be an elastic element such as a spring, a pneumatic rod or a hydraulic rod.

[0168] Correspondingly, as shown in Figures 31 and 32, the foot pedal connecting member 830 also includes a through foot pedal locking hole 822 disposed on the connecting ear 820, the size and shape of which are configured to allow the foot pedal locking member 831 to pass through it, thereby enabling the foot pedal locking member 831 to extend into and exit from the foot pedal locking hole 822.

[0169] In other embodiments, alternatively, the foot pedal locking hole 822 may also be a non-through hole, but a blind hole provided on the connecting ear 820, which only extends through a portion of the thickness of the connecting ear 820. That is, in the extending direction of the foot pedal body 810, the foot pedal locking hole 822 only extends through a portion of the connecting ear 820 and does not pass through the connecting ear 820. The foot pedal locking hole 822 provided in this way can also realize the engagement and disengagement of the foot pedal locking member 831 and the foot pedal locking hole 822.

[0170] When installing the foot pedal 800, the user only needs to press the foot pedal locking member 831 to retract it along the extension direction of the foot pedal body 810, and then align the foot pedal locking hole 822 on the connecting ear 820 with the foot pedal locking member 831. Then, after the user stops pressing the foot pedal locking member 831, the foot pedal locking member 831 can extend into the foot pedal locking hole 822 along the extension direction of the foot pedal body 810 under the elastic force of the resetting elastic member 832, thereby completing the installation of the foot pedal 800.

[0171] When disassembling or adjusting the foot pedal 800, the user only needs to press the foot pedal locking member 831 to disengage it from the foot pedal locking hole 822 along the extension direction of the foot pedal body 810. Thus, the user can remove the foot pedal 800 or flip the foot pedal body 810 up and down between the first mounting position and the second mounting position.

[0172] In other embodiments, alternatively, the foot pedal locking hole can be provided on the front support leg connecting seat 230, the foot pedal locking member can be provided on the connecting ear 820, and the foot pedal locking member can extend and retract along the extension direction of the foot pedal body 810 to engage or disengage with the foot pedal locking hole. When it is necessary to install, remove, or adjust the foot pedal 800, the user only needs to press the foot pedal locking member 831 to retract it, so that the foot pedal locking member 831 engages with the foot pedal locking hole 822.

[0173] In other embodiments, alternatively, the foot pedal locking member 831 itself may be a deformable structure, such as an elastic element, which deforms when pressed, thereby reducing its size in the extending direction of the foot pedal body 810, thus allowing the foot pedal locking member 831 to engage with the foot pedal locking hole 822 to connect the foot pedal 800 to the front support leg connecting seat 230. In this embodiment, since the foot pedal locking member 831 itself is a deformable structure, there is no need to provide a resetting elastic element. When it is necessary to install, remove, or adjust the foot pedal 800, the user only needs to press the foot pedal locking member 831 to deform and retract it, so that the foot pedal locking member engages with the foot pedal locking hole.

[0174] After the foot pedal 800 is installed, in order to ensure that the foot pedal body 810 does not accidentally flip between the first installation position and the second installation position, in the embodiments shown in Figures 30 to 34, a limiting block 232 may be provided on the front support leg connecting seat 230. The limiting block 232 may be square (see Figure 30) or elliptical, polygonal or other shapes that can prevent the foot pedal body 810 from flipping.

[0175] In the embodiments shown in Figures 30, 33 and 34, the foot pedal locking member 831 may be configured to be located at the limiting block 232. Specifically, as shown in Figure 33, the foot pedal locking member 831 may pass through approximately the middle of the limiting block 232 and be movably configured relative to the limiting block 232.

[0176] Correspondingly, as shown in Figures 31 and 32, the connecting ear 820 is provided with a limiting groove 823, the size and shape of which correspond to the limiting block 232. The side edge of the limiting block 232 can engage with the limiting groove 823, so that the limiting block 232 can engage with the limiting groove 823, so that the foot pedal 800 is limited in at least one direction.

[0177] Furthermore, to facilitate the engagement of the limiting block 232 with the limiting groove 823, as shown in Figures 31 and 32, the limiting groove 823 is provided with a lateral opening 823A facing at least one direction, or in other words, the limiting groove 823 is open in at least one direction so that the limiting block 232 can be inserted into the limiting groove 823 through the lateral opening 823A. In this case, through the cooperation between the limiting block 232 and the limiting groove 823, the foot pedal 800 can be limited in directions other than the direction in which the lateral opening 823A is provided.

[0178] Specifically, as shown in Figure 31, when the foot pedal 800 is flipped to a lower position, the lateral opening 823A of the limiting groove 823 faces the front of the seat 100. At this time, the foot pedal 800 can be inserted into the limiting block 232 from back to front, thereby installing the foot pedal 800 onto the front support leg 200. As shown in Figure 32, when the foot pedal 800 is flipped to a higher position, the lateral opening 823A of the limiting groove 823 faces the rear of the seat 100. At this time, the foot pedal 800 can be inserted into the limiting block 232 from front to back, thereby installing the foot pedal 800 onto the front support leg 200.

[0179] In other embodiments, alternatively, the limiting groove 823 may open in other directions (i.e., the lateral opening 823A faces other directions). For example, when the foot pedal 800 is flipped to a lower position, the limiting groove 823 opens above or below the seat 100. In this case, the foot pedal 800 can be inserted into the limiting block 232 from bottom to top or from top to bottom, thereby mounting the foot pedal 800 to the front support leg 200. It is understood that other opening orientations of the limiting groove 823 are also conceivable, such as an oblique opening, in which case the insertion direction of the foot pedal 800 and the limiting block 232 is oblique.

[0180] In other embodiments, alternatively, the limiting groove 823 may also be provided with two lateral openings, or openings in two directions. For example, when the foot pedal 800 is flipped to a lower or higher position, the limiting groove 823 opens towards the front-rear direction of the seat 100, at which time the foot pedal 800 can be inserted into the limiting block 232 from front to back or from back to front; or, when the foot pedal 800 is flipped to a lower or higher position, the limiting groove 823 opens towards the vertical direction of the seat 100, at which time the foot pedal 800 can be inserted into the limiting block 232 from top to bottom or from bottom to top. It is also understood that the limiting groove 823 may also be conceived to have a bidirectional opening along an oblique direction.

[0181] In other embodiments, the limiting block 232 can also be disposed on the connecting ear 820, and the limiting groove can be disposed on the front support leg connecting seat 230, so that the foot pedal 800 can be connected to the front support leg connecting seat 230.

[0182] In addition, since both the limiting block 232 and the limiting groove 823 are square, elliptical or polygonal, after they are joined together, the limiting groove 823 is restricted by the limiting block 232 located inside it and cannot rotate, thereby making it impossible for the foot pedal body 810 where the limiting groove 823 is located to flip over.

[0183] In addition, in some embodiments, the foot pedal 800 may also have the function of storing the tray 700. As shown in FIG20, the two end faces of the foot pedal body 810 along the lateral width direction of the seat 100 may be provided with foot pedal engagement holes 840 respectively. Correspondingly, as shown in FIG13, the tray 700 is provided with a tray boss 730. The foot pedal engagement hole 840 can engage with the tray boss 730. When the tray 700 is no longer needed and is removed from the armrest 600, the tray 700 can be stored in the foot pedal 800 by means of the engagement of the foot pedal engagement hole 840 and the tray boss 730, thereby providing a storage location for the tray 700 and effectively preventing the tray 700 from being lost.

[0184] In some embodiments, each end face of the foot pedal body 810 is provided with two foot pedal engaging holes 840 spaced apart in the front-rear direction. Preferably, the front and rear foot pedal engaging holes 840 are located on both sides of the foot pedal connecting member 830 in the front-rear direction, so that after the foot pedal body 810 is flipped up and down, regardless of whether the foot pedal 800 is in the first installation position or the second installation position, the tray 700 can be stored behind the foot pedal 800, that is, between the front support leg 200 and the rear support leg 300. In this way, regardless of whether the foot pedal 800 is in the first installation position or the second installation position, the storage of the tray 700 on the foot pedal 800 will not hinder the normal use of the foot pedal, while improving the overall aesthetics of the product.

[0185] Another aspect of this disclosure provides a locking device 500, which includes a locking member 520 movably connected to an object to be locked and movable along a first direction D1 between a locked position and an unlocked position. The structure and features of the locking member 520 are as described above. In some embodiments, the locking member 520 includes a first locking member 521 and a second locking member 522 that are movable relative to each other. The structure and features of the first locking member 521 and the second locking member 522 are as described above. The object to be locked can be the aforementioned high chair, or other structures, such as a trolley, a bed, etc.

[0186] In some embodiments, the locking device 500 may further include a fixing seat 510, which is fixedly connected to the seat 100, and the locking member 520 is movably connected to the fixing seat 510. The structure and features of the fixing seat 510 are as described above.

[0187] In some embodiments, the locking device 500 may further include an operating member 530, which is movably connected to the fixed base 510 and can drive the locking member 520 to move. The structure and features of the operating member 530 are as described above.

[0188] In some embodiments, the locking device 500 may further include a locking elastic member 540, which may be disposed, for example, between the first locking member 521 and the second locking member 522, and thus configured to move the first locking member 521 and the second locking member 522 away from each other to a locked position and remain in the locked position, the structure and features of the locking elastic member 540 being as described above.

[0189] Since the features of this disclosure can be embodied in various forms without departing from the nature of this disclosure, it should also be understood that the above embodiments are not limited to any of the details described above, unless otherwise stated, and should be broadly interpreted as falling within the scope defined by the appended claims. Therefore, all modifications and alterations falling within the scope and limits of the claims or equivalent solutions of such scope and limits should be covered by the appended claims.
