Description

Technical Field

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

[0002] High chairs are typically used for children's meals. To extend their lifespan, existing high chairs generally feature multiple usage modes. These include a seat and supporting legs connected to it. The supporting legs are designed to be detachable in multiple sections, with different lengths connected to the seat. Combined with accessories such as trays and footrests, 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, different from the first direction, wherein the operating member, when operated, causes the locking member to move between a locked position and an 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, so as 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 and exit 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, and the guide ramp guides the locking member to extend into and exit the locking hole during the transition of the high chair between the unfolded state and the folded state.

[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.

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

[0012] In one embodiment, the high chair includes two front legs, with a footrest detachably connected between the two front legs. The footrest includes a footrest body extending laterally between the two front legs, and connecting ears protruding from both ends of the footrest body in a direction perpendicular to the extending direction of the footrest body. The connecting ears are connected to the front legs via a footrest connecting member, allowing the footrest body to 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 foot pedal engaging holes on two end faces along the lateral width direction. The foot pedal engaging holes can engage with tray bosses 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, preventing the connector from rotating to the closed position; when the locking member is in the unlocked position, the locking part no longer limits the connector locking rod, allowing the connector to 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, thereby enabling the connector to be rotatably connected to the seat, and the retractable elastic element 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 is not engaged 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 including a locking member movably connected to an object to be locked and movable along a first direction between a locked position and an unlocked position.

[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.

[0174] This disclosure will now be described in detail with reference to the accompanying drawings.

[0175] Figures 1 to 4 An embodiment of a high chair 1 according to one aspect of the present disclosure is shown. It should be understood that although the high chair 1 shown in the figure 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.

[0176] For ease of description, such as Figure 1 and Figure 4 As shown, this article defines the direction a child faces when sitting in highchair 1 as "front" and the direction they face as "back". The direction perpendicular to the front-back direction on the horizontal plane is defined as the left-right direction or the width of the seat.

[0177] like Figures 1 to 4 As shown, 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. Alternatively, the front leg 200 may be pivotally connected to the seat 100, while the rear leg 300 may be fixedly connected to the seat 100; or the front leg 200 may be pivotally connected to the seat 100, and the rear leg 300 may also be pivotally connected to the seat 100. This application is not limited to these embodiments. Furthermore, the legs may 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 unfold and fold.

[0178] In some embodiments, such as Figures 1 to 4 The high chair 1 shown 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.

[0179] 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, 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 children are 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.

[0180] 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 and fold and unfold.

[0181] In some embodiments, such as Figure 10 As shown, 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 has a connector connection hole 420. Correspondingly, the bottom of the seat 100 has 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.

[0182] like Figure 10As shown, 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.

[0183] Of course, the connector 400 can also be rotatably connected to the seat 100 in other ways. For example, the connector 400 may have a connecting shaft, and the bottom of the seat 100 may have a connecting hole through which the connecting shaft passes. Alternatively, the connector 400 may have a cylindrical protrusion, and the bottom of the seat 100 may have a cylindrical recess that accommodates the protrusion and allows the protrusion to rotate within it. The connector 400 is rotatably connected to the seat 100 through the cooperation of the protrusion and the recess.

[0184] Because 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 usage state, such as... Figure 1 As shown; 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. Figure 6 As shown, this design saves storage space. Additionally, the high chair 1 can be folded up to stand, making it easy to store.

[0185] 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.

[0186] 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.

[0187] Figures 8 to 10 An embodiment of the locking device 500 according to the present disclosure is shown.

[0188] In this embodiment, the locking device 500 includes a locking member 520, which is movably connected to the seat 100 and is capable of being positioned relative to the connector 400 along a first direction D1 (see [link]). Figure 8 and Figure 9The locking element 520 moves between a locked position and an unlocked position, the first direction D1 being, for example, the lateral width direction of the seat 100; that is, the locking element 520 can move along the lateral width direction of the seat 100. Figure 8 As shown, when the locking member 520 is in the locked position, it extends into or inserts into the locking hole 410 on the connector 400, thereby preventing the connector 400 from driving the rear support leg 300 to rotate relative to the seat 100, thus keeping the bar chair 1 in the unfolded or folded state. Figure 9 As shown, when the locking member 520 is in the unlocked position, it disengages from the locking hole 410 on the connector 400, thereby allowing the connector 400 to rotate the rear support leg 300 relative to the seat 100, enabling the high chair 1 to switch between an extended and retracted state. In this embodiment, the locking hole 410 on the connector 400 is located behind the connecting hole 420, facilitating the retraction and rearward extension of the rear support leg 300. In other embodiments where the front support leg 200 can pivotally retract, the locking hole 410 may be located in front of the connecting hole 420, facilitating the retraction and forward extension of the front support leg 200.

[0189] Although Figures 8 to 10 In the illustrated embodiment, only one set of locking holes 410 is shown, used to hold 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 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.

[0190] When the high chair 1 is in the folded position, as Figure 6 As shown, the high chair 1 can stand upright when folded, making it easy to store.

[0191] In some embodiments, such as Figure 10 As shown, the locking device 500 may further include a fixing seat 510, which is fixedly connected to the seat 100, while 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 can be positioned at other locations on the seat 100 as needed. In some embodiments, the fixing seat 510 may also be integrally formed with the seat 100; that is, a separate fixing seat 510 connected to the seat 100 may not be required.

[0192] To facilitate the movement of the locking element 520, in some embodiments, such as Figures 8 to 10As shown, the locking device 500 may further include an operating member 530, which is movably connected to the fixed base 510 and capable of driving the locking member 520 to move. Specifically, the operating member 530 is movable relative to the seat 100 along a second direction D2 (see...). Figure 8 and Figure 9 The movement of the locking member 520 along the first direction D1 causes it to move between the locked and unlocked positions. 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 vertical 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 driving the locking member 520 to move according to the operation member 530 of this disclosure.

[0193] Figure 11 and Figure 12 An embodiment of the locking element 520 and the operating element 530 according to this disclosure is shown. Figure 11 and Figure 12 As shown, 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 each provided with a protruding part extending in the relative movement direction, which can be inserted into a corresponding locking hole 410. In this embodiment, the first locking member 521 and the second locking member 522 adopt a sleeve structure that interlocks with each other. 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 between the two is achieved through the mating structure of the guide groove and the guide rail.

[0194] In order for 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 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 that abuts against the first mating inclined surface 521A (see...). Figure 12 ), and a second driving ramp 532 that abuts against the second mating ramp (522A) (see Figure 11 ).

[0195] exist Figure 11 and Figure 12In the illustrated embodiment, the operating element 530 may take the form of a button for user operation. When the operating element 530 is operated (i.e., the user applies a pressing force to the operating element 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 closer together and move to the unlocked position. Thus, as Figure 9 As shown, 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 base 100.

[0196] like Figure 12 As shown, 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. During this process, the first mating ramp 521A on the first locking element 521 and the second mating ramp 522A on the second locking element 522 will respectively apply forces to the first driving ramp 531 and the second driving ramp 532 of the operating member 530, thereby driving the operating member 530 to an initial position in preparation for the next release of the locking device 500.

[0197] The locking elastic element 540 can be an elastic element such as a spring, a pneumatic rod, or a hydraulic rod.

[0198] When a user unfolds the high chair 1, it may be in a partially unfolded state. In one embodiment, preferably, to prevent the high chair 1 from being in this partially unfolded state, a folding limiting mechanism can be provided inside the high chair 1, so that the high chair 1 can only be fully unfolded... Figure 42 The fully unfolded state shown is the same as Figure 43 Switch between the folded and unfolded states as shown to avoid an incompletely unfolded state.

[0199] like Figures 45 to 47 As shown, the high chair 1 equipped with a retraction limiting mechanism and Figures 8 to 12 The high chair shown is basically the same as the one shown, except that a folding and limiting mechanism has been added.

[0200] 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.

[0201] exist Figures 48 to 50 and Figures 53 to 55 In the illustrated embodiment, 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.

[0202] like Figure 53 As shown, 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.

[0203] In one embodiment, the first end 111A of the torsion spring 111 is connected to a torsion spring fixing protrusion 491 on the connecting portion 490 of the connector 400 (see [link]). Figure 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...). Figure 55 ).

[0204] Since the retractable elastic element 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 element 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.

[0205] 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 protrusion, etc.

[0206] exist Figures 47 to 52 In the illustrated embodiment, 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 following the first locking member 521 and the second locking member 522 relative to the seat 100 along a first direction D1 (see Figure 47The connector 400 is retractable and, when extended, prevents rotation of the connector 400 from the retracted position to the extended position. In other embodiments, the first limiting member 521B and the second limiting member 522B can be configured to prevent rotation of the connector 400 from the extended position to the retracted 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 they may include multiple limiting members disposed on the first locking member 521 and the second locking member 522.

[0207] 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 additionally used to prevent the connector from rotating from the folded position to the unfolded position, such as... Figure 51B As shown.

[0208] In this case, Figure 51B Taking the second locking part 522C as an example, when viewed from the left and 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.

[0209] Of course, this disclosure is not limited to this. 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.

[0210] When the high chair 1 is in the folded state, the second limiting member 522B is in the extended state along with the second locking member 522 (e.g., Figure 51A As shown), the first limiting member 521B is also in the extended state (not shown) along with the first locking member 521. Therefore, the second limiting member 522B and the first limiting member 521B will block the upper edge of the connector 400, making it impossible for the connector 400 to rotate toward the closed position.

[0211] 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.

[0212] The connector 400 is provided with connector limiting holes 480 that respectively mate with the second limiting member 522B and the first limiting member 521B. When the connector 400 is rotated to the unfolded position, as... Figure 52 As shown, 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, respectively. Simultaneously, 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, respectively, 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.

[0213] exist Figure 51B In the embodiment shown without 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 an additional 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 held in the unfolded state.

[0214] 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.

[0215] It should be understood that the locking device 500 according to this disclosure is not limited thereto.

[0216] 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, causing the gear at one end to rotate, the engagement of the gear and the rack converts the rotation of the gear into the movement of 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 require the locking member 520 to be inserted into or removed from 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 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 is prevented or allowed by hooking or disengaging the hook from the hanging ring.

[0217] In some embodiments, to facilitate the user's unfolding of the high chair 1, such as... Figure 10 As shown, the connector 400 may be provided with a guide ramp 430, which extends from the upper end of the connector 400 along an inclined direction to the locking hole 410 or to the vicinity of the locking hole 410. This allows the locking member 520 to be extended and abut against the upper end of the guide ramp 430 when the high chair 1 is in the folded state. When the high chair 1 is unfolded, as its legs and connector 400 unfold, the locking member 520 is compressed by the guide ramp 430 and slides along the guide ramp 430 relative to the connector 400 to the locking hole 410. Subsequently, the locking member 520 extends and inserts into the locking hole 410 under the elastic force of the locking elastic member 540. Thus, the user only needs to pull the legs to unfold the high chair 1 without operating the operating member 530.

[0218] In some embodiments, such as Figure 10 , Figure 24 , Figure 26 As shown, the upper end of the connector 400 may also be provided with an abutting upper edge 440. When the connector 400 and the rear support leg 300 connected thereto rotate 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 the rear support leg 300 connected thereto 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.

[0219] In some embodiments, such as Figure 10 , Figure 24 , Figure 26 As shown, 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 are rotated to the unfolded position, the limiting wall 130 abuts against the connecting member 400 to restrict the connecting member 400 from continuing to rotate in the same direction (see [reference]). Figure 24 Therefore, the limiting wall 130 can also limit the rotation angle of the connector 400 and the rear support leg 300 connected thereto toward the unfolded position, and can make the connector 400 supported by the bottom of the seat 100, so as to improve the stability of the high chair 1 in the unfolded state.

[0220] In some embodiments, such as Figure 24 and Figure 26 As shown, the bottom of the seat 100 may also be provided with a limiting rib 140 and a guide rib 150. The limiting rib 140 and the guide rib 150 extend outward from the bottom, respectively. The guide rib 150 is located in front of the limiting 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 The leading edge 450 of the connector is close to the guide rib 150; when the connector 400 and its connected rear support leg 300 rotate to the retracted position, the leading edge 450 of the connector 400, guided by the guide rib 150, abuts against the limiting rib 140, thereby restricting 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.

[0221] In some embodiments, such as Figure 27 As shown, a limiting middle portion 160 may be provided on the bottom of the seat 100, which is positioned between the two leading 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 its connected rear support leg 300 rotate to the folded position, the limiting middle portion 160 abuts against the connector limiting portion 460, restricting the connector 400 from continuing to rotate in the same direction. This limits the rotation angle of the connector 400 and its connected rear support leg 300 toward the folded position, and improves the stability of the high chair 1 in the folded state.

[0222] Figures 35 to 41A locking device 500I according to another embodiment of the present disclosure is shown.

[0223] In this embodiment, such as Figure 36 As shown, the locking device 500I includes a locking member 520I, which is movably connected to the seat 100 and is capable of being positioned relative to the connector 400 in a third direction D3 (see Figure 100). Figure 40 It moves between the locked and unlocked positions. For example... Figure 37 , Figure 38 , Figure 40 and Figure 41 As shown, the locking member 520I is provided with a locking portion 523I. This third direction D3 is, for example, the fore-and-aft direction of the seat 100, that is, the locking member 520I can move 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, it extends parallel to the horizontal plane.

[0224] Correspondingly, such as Figures 39 to 41 As shown, the connector 400I is provided with a connector locking lever 470I. 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 member 520I moves to the locking position, as... Figure 40 As shown, in the unfolded state of the seat 100, the upper end of the locking part 523I can block the connecting locking rod 470I, preventing the connecting member 400I and its connected rear support leg 300 from rotating relative to the seat 100 to the folded position within a certain range or limit; when the locking part 520I moves to the unlocked position, as Figure 41 As shown, in the unfolded state of the seat 100, the locking part 523I no longer obstructs the connecting member locking rod 470I, allowing the connecting member 400I and the rear support leg 300 connected thereto to rotate around the connecting shaft 110 (see...). Figure 38 Meanwhile, the seat 100 rotates to the folded position.

[0225] Specifically, in the unfolded state of the seat 100, the upper surface of the locking part 523I can tightly abut against the connecting locking rod 470I, thus completely blocking the connecting locking rod 470I from rotation. Alternatively, in the unfolded state of the seat 100, the upper surface 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. After it rotates a small angle toward the folded position, it is blocked by the upper surface of the locking part 523I and cannot continue to rotate.

[0226] In this disclosure, when the high chair 1 is in the folded state, the connector 400 and the rear support leg 300 are respectively in the folded position; when the high chair 1 is in the unfolded state, the connector 400 and the rear support leg 300 are respectively in the unfolded position.

[0227] 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 moved toward the unfolded position by an applied force, 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 connected rear support leg 300 to eventually rotate to the unfolded position without applying an additional forward force to the locking member 520I.

[0228] Understandably, in other embodiments, the lower end face 524I of the locking part 523I may extend along a third direction D3, that is, parallel to the horizontal plane. In this case, when the rear support leg 300 is in the retracted position and is rotated backward by force, 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 and preventing the rear support leg 300 from rotating 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.

[0229] In one embodiment, to facilitate operation of the locking member 520I and its movement between the locked and unlocked positions, in Figures 39 to 41 In the illustrated embodiment, 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 a locked position and an unlocked position when operated.

[0230] like Figure 40 As shown, 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.

[0231] 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 [link]). Figure 40 and Figure 41 (As shown by the dashed line in the diagram), so that the operating element 530I can better push the locking element 520I to move.

[0232] On the other hand, the operating member 530I can also be operated to retract outward along the third direction D3 back to its 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 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.

[0233] In another embodiment, 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 outward.

[0234] like Figure 45 As shown, a front foot pad 201 can be provided at the bottom of the front support leg 200, and a rear foot pad 201 can be provided at the bottom of the rear support leg 200 to reduce 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 a support inclined surface to provide more stable support for the high chair 1.

[0235] exist Figure 14 In the illustrated embodiment, the high chair 1 may further include armrests 600 detachably attached to the seat 100. When a smaller child (e.g., an infant older than 6 months) sits in the high chair 1, as... Figure 1 As shown, armrests 600 can be attached to the seat 100 to protect the smaller child from accidental detachment from the seat 100, and to the armrests 600 for attaching items such as a tray 700 (described later). When an older child (e.g., a child older than 3 years old) sits in the highchair 1, as... Figure 2 As shown, seat 100 does not need to be connected to armrest 600, giving children more freedom.

[0236] The armrest 600 may include an armrest connector 610, which is capable of engaging with a seat connector 120 on the seat 100. Figure 15In the illustrated embodiment, the armrest glove joint 610 is a cover-shaped part located at both ends, which can connect with the protruding seat joints 120 on both sides of the seat 100 (see...). Figure 2 and Figure 16 This is in conjunction with the armrest 600 so that it can be easily and quickly connected to the seat 100.

[0237] In some embodiments, to enhance the connection between the armrest 600 and the seat 100, such as Figure 15 As shown, the armrest joint 610 may be provided with an armrest connecting piece 611, which can be inserted into the seat connecting hole 121 on the seat joint 120 (see...). Figure 16 ).exist Figure 15 In the illustrated embodiment, 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...). Figure 16 ), and can allow the handrail connecting piece 611 to be inserted into it.

[0238] Furthermore, such as Figure 15 As shown, the armrest connecting piece 611 of the armrest joint 610 may be provided with a connecting piece engagement hole 612. Correspondingly, as... Figure 16 As shown, the inner wall of the seat connection hole 121 of the seat connection part 120 is provided with connection hole fingers 122. The connection hole fingers 122 are elastic and extend outward from the inner wall of the seat connection hole 121 in a cantilever form. Figure 18 As shown, because 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 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. By means of the engagement of the connecting piece engaging hole 612 and the connecting hole finger 122, the armrest 600 can be effectively prevented from accidentally detaching from the seat 100, thereby ensuring the safety of children sitting in the seat 100.

[0239] In addition, such as Figure 18 As shown, the interior of the seat connection portion 120 is hollow and has an opening at the bottom, allowing the armrest connecting piece 611, which is inserted into the seat connection hole 121, to protrude from the lower part of the seat connection portion 120. Thus, the user can contact the armrest connecting piece 611 through the lower opening of the seat connection portion 120 and apply force to it, causing the armrest connecting piece 611 to disengage from the connecting hole finger 122, thereby allowing the armrest connecting piece 611 to exit the seat connection hole 121, and subsequently allowing the armrest 600 to be detached from the seat 100.

[0240] The armrest connecting piece 611 can be integrally formed with the armrest joint 610, or it can be formed separately.

[0241] exist Figure 56 In another embodiment of the handrail 600 shown, 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 mating part 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.

[0242] Correspondingly, such as Figure 58 As shown, 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, and the engagement finger 125 is configured to engage with the connecting hole engagement hole 612 on the armrest connecting piece 611 (see [reference]). Figure 59 This prevents the armrest connecting piece 611 from exiting the seat connecting hole 121, thus avoiding the armrest 600 from accidentally detaching from the seat 100.

[0243] To further strengthen the connection between the armrest 600 and the seat 100, the armrest joint 610 may also be provided with a connecting piece limiting hook 614, such as... Figure 56 As shown, it can be inserted into the seat limiting hole 123 on the seat connecting part 120 (see...). Figure 57 and Figure 58 It engages with the seat 100 to form an inverted fit, thereby further securing the armrest 600 to the seat 100.

[0244] exist Figure 1 In the illustrated embodiment, the high chair 1 may also include a tray 700, which is detachably attached to the armrest 600. The tray 700 can greatly expand the functionality of the high chair 1, as it can be used not only as a child's plate for placing children's bowls, plates, or food, but also as a child's work surface for placing children's toys.

[0245] To ensure that the tray 700 remains fixed relative to the handrail 600 after being installed on it, such as... Figure 13 As shown, 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 of the seat 100. The tray engaging block 710 also includes a tray engaging protrusion 711 that protrudes inward along the lateral width of the seat 100. Correspondingly, as Figure 14As shown, the armrest 600 has an armrest recess 620. When the tray engaging block 710 moves to the engaging 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 can 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.

[0246] Furthermore, such as Figure 18 As shown, the tray 700 may be provided with a tray elastic element 720, which is configured to tend to move the tray engaging block 710 to the engagement position. This ensures the relative fixation between the tray 700 and the handrail 600.

[0247] Optionally, the surface of the tray engaging protrusion 711 is beveled. 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. A downward force is applied to the tray 700. Due to the beveled surface, the tray engaging protrusion 711 will move outward along the 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.

[0248] 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.

[0249] like Figure 19 and Figure 20 As shown, 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.

[0250] The design of the connecting ear 820 extends the effective service life of the foot pedal 800. When the connecting ear 820 is connected to the front support leg 200 via the foot pedal connecting member 830 (such as a connecting bolt), the foot pedal body 810 can be tilted up and down. Specifically, the foot pedal 800 has two mounting positions. The first mounting position is with the connecting ear 820 located below the foot pedal body 810, such as... Figure 19 As shown, this positions the footrest body 810 closer to the seat 100, making it suitable for younger children. The second installation position is with the connecting ear 820 located above the footrest body 810, as shown... Figure 21 As shown, this allows the footrest body 810 to be positioned further away from the seat 100, making it suitable for older children. The footrest body 810 can be tilted up and down between the first and second mounting positions to meet the needs of children at different stages.

[0251] In some embodiments, such as Figure 22 As shown, 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 design that is flat at the top and wide at the bottom, 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 horizontal width direction of the seat 100, extends vertically; 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 horizontal width direction of the seat, extends vertically. 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, a square protrusion 821 is provided on the outer end face of the connecting ear 820 (see Figure 20 The front outrigger connecting seat 230 has a square recess 231 on its inner side (see...). Figure 22 The two work together to ensure that the foot pedal body 810 will not accidentally flip between the first installation position and the second installation position after the foot pedal 800 is installed.

[0252] The front outrigger connector 230 can be fixed to the front outrigger 200 using screws or other fasteners, such as... Figure 33 As shown.

[0253] Figures 28 to 34 Another embodiment of the foot pedal 800 according to the present disclosure is shown. In this embodiment, the structure of the connecting lug 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 embodiment, as described in detail below.

[0254] In this embodiment, as Figures 28 to 30 and Figure 33 , Figure 34 As shown, the foot pedal connecting member 830 may include a foot pedal locking member 831 disposed on the front support leg connecting seat 230, which 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.

[0255] exist Figure 33 In the illustrated embodiment, a reset 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 reset elastic element 832 may be an elastic element such as a spring, a pneumatic rod, or a hydraulic rod.

[0256] Correspondingly, such as Figure 31 and Figure 32 As shown, 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 the foot pedal locking hole 822.

[0257] 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.

[0258] 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 reset elastic member 832, thereby completing the installation of the foot pedal 800.

[0259] 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. The user can then remove the foot pedal 800 or flip the foot pedal body 810 up and down between the first and second mounting positions.

[0260] In other embodiments, alternatively, the foot pedal locking hole can be provided on the front outrigger connector 230, and the foot pedal locking member can be provided on the connecting ear 820. 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.

[0261] In other embodiments, alternatively, the foot pedal locking member 831 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. This allows 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 is a deformable structure, there is no need to provide a reset 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, allowing the foot pedal locking member to engage with the foot pedal locking hole.

[0262] After the foot pedal 800 is installed, to ensure that the foot pedal body 810 does not accidentally flip between the first and second installation positions, Figures 30 to 34 In the illustrated embodiment, a limiting block 232 may be provided on the front outrigger connecting seat 230. This limiting block 232 may be square (see [reference needed]). Figure 30 Or an oval, polygonal, or other shape that can prevent the foot pedal body 810 from flipping.

[0263] exist Figure 30 , Figure 33 and Figure 34 In the illustrated embodiment, the foot pedal locking member 831 can be positioned at the limiting block 232. Specifically, as shown... Figure 33 As shown, the foot pedal locking member 831 can pass through approximately the middle of the limiting block 232 and be movably set relative to the limiting block 232.

[0264] Correspondingly, such as Figure 31 and Figure 32 As shown, 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.

[0265] In addition, to facilitate the engagement of the limiting block 232 and the limiting groove 823, such as Figure 31 and Figure 32 As shown, the limiting groove 823 has 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, by the cooperation of 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.

[0266] Specifically, such as Figure 31 As shown, 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. Figure 32 As shown, 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 on the front support leg 200.

[0267] 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, at which point 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.

[0268] 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 be conceived to have a bidirectional opening along an oblique direction.

[0269] 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, which can also realize the connection between the foot pedal 800 and the front support leg connecting seat 230.

[0270] Furthermore, 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 preventing the foot pedal body 810 where the limiting groove 823 is located from flipping over.

[0271] Additionally, in some embodiments, the foot pedal 800 may also function as a tray holder 700. For example... Figure 20 As shown, the foot pedal body 810 may have foot pedal engaging holes 840 on its two end faces along the lateral width of the seat 100. Correspondingly, as... Figure 13 As shown, the tray 700 has 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 detached from the armrest 600, the tray 700 can be stored in the foot pedal 800 by means of the engagement between the foot pedal engagement hole 840 and the tray boss 730, thus providing a storage location for the tray 700 and effectively preventing the tray 700 from being lost.

[0272] 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. Thus, 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.

[0273] 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.

[0274] 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.

[0275] 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.

[0276] 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.

[0277] 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, and unless otherwise stated, 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 equivalents thereof should be covered by the appended claims.
