Description
[Technical Field]
[0001] This utility model relates to a children's chair. [Background Technology]
[0002] Child chairs are a common product in a child's growth process. Currently, child chairs generally consist of two front legs and two rear legs connected to them. The seat is placed between the front and rear legs, and the sides of the seat are locked to the front and rear legs by locking mechanisms. When it is necessary to remove the seat, both hands must be pressed to unlock the locking mechanism at the same time, and the seat must be lifted upwards at the same time to remove the seat, which is very inconvenient.
[0003] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a children's chair with a simple structure and easy seat disassembly.
[0005] This utility model is achieved through the following technical solution:
[0006] A child chair includes two front legs and two rear legs spaced apart in a left-right direction. Each front leg has a front connecting seat at its upper end, and each rear leg has a rear connecting seat at its upper end. The front connecting seats are connected to the rear connecting seats on the same side. A detachable seat is provided between the two front connecting seats. A locking mechanism is provided between the seat and the front connecting seats. The locking mechanism includes a locking slot on the seat. The front connecting seats have a locking pin that can slide within the locking pin and engage or disengage from it. The front connecting seats have an operating block that can slide relative to the operating block to drive the locking pin to disengage from the locking slot. An unlocking retaining component is provided between the operating block and the front connecting seats to keep the locking mechanism unlocked after the operating block drives the locking pin to disengage from the locking slot. The unlocking retaining component has a mating part that can be pushed by the seat when the seat is removed. The front connecting seats have an elastic element that can push the operating block and the locking pin back to their original positions when the seat pushes the mating part.
[0007] The elastic element includes a first return spring disposed between the front connecting seat and the locking pin, capable of pushing the locking pin to move, and a second return spring disposed between the front connecting seat and the operating block, capable of pushing the operating block to reset.
[0008] The unlocking and holding assembly includes a locking block that slides within the operating block. The front connecting seat has a locking hole that engages with the locking block to prevent the operating block from resetting when the operating block moves to unlock. A second spring is provided between the locking block and the operating block, which can push the locking block out and engage it with the locking hole when the locking block is aligned with the locking hole. The mating part is an inclined surface located on the underside of the locking block that can be pushed by the seat when the seat is removed, causing the locking block to slide into the operating block.
[0009] The seat is detachably connected to a plate.
[0010] The child chair also includes a support plate on the front and rear support legs, and a protective frame that can be locked to the front connecting seat by a locking mechanism after the seat is removed.
[0011] The protective frame includes an annular frame with connecting parts on both sides. The connecting parts are provided with locking holes that can engage or disengage with the locking pin. When the protective frame is removed, it can push the mating part on the locking block to slide the locking block into the operating block, thereby causing the operating block to reset under the push of the first spring.
[0012] The front connecting seat and the rear connecting seat are rotatably connected. A crossbar is provided between the two rear support legs. The front side of the bearing plate is rotatably connected to the middle of the two front support legs. A linkage rod is provided between the middle of the bearing plate and the crossbar, which is rotatably connected to both. A locking assembly is provided between the rear side of the bearing plate and the crossbar. When the front support legs rotate and fold relative to the rear support legs, the rear side of the bearing plate moves to a position close to the front connecting seat.
[0013] The locking assembly includes a sliding block that can slide relative to the support plate. The sliding block is provided with a latch that can lock or disengage from the crossbar when it slides. A third spring is provided between the sliding block and the support plate to push the sliding block to reset.
[0014] The latch is provided with an inclined wall that can compress the crossbar and cause the sliding block to slide when the front and rear outriggers are deployed.
[0015] The front support leg is also equipped with a foot pedal.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. The seat of this child chair is locked to the front connecting seat via a locking mechanism. When the seat needs to be removed, simply press and slide the operating block. The operating block drives the locking pin to disengage from the locking position on the seat, thus unlocking the seat from the front connecting seat. During the sliding process of the operating block, the unlocking retaining component maintains the unlocked state of the seat from the front connecting seat, eliminating the need for the user to continuously press the operating block. Therefore, after pressing the operating block, the user can free their hand to lift the seat, making seat removal easier. Furthermore, when the seat is removed, it pushes against the mating part on the unlocking retaining component, causing the unlocking retaining component to move. After the unlocking retaining component moves, the elastic element pushes the operating block and locking pin to slide back to their initial state. Therefore, this utility model has a simple structure, facilitates seat removal, and allows for smooth reset of the operating block, making it suitable for widespread application.
[0018] 2. After the seat and guard frame are removed, the front and rear support legs of this utility model child chair can rotate relative to each other. At this time, the support plate rotates relative to the front support leg, and the linkage rod rotates relative to the rear support leg and the support plate, thereby moving the rear side of the support plate to a position close to the front connecting seat. Finally, the front support leg, rear support leg, support plate and linkage rod come together to complete the folding for easy storage. [Attached Image Description]

Detailed Implementation Methods
[0032] The present invention will be further described below with reference to the accompanying drawings:
[0033] like Figures 1 to 10 As shown, a child chair includes two front legs 1 and two rear legs 2 spaced apart from each other in a left-right direction. The lower ends of the front legs 1 and rear legs 2 are supported on the ground. Each front leg 1 has a front connecting seat 3 at its upper end, and each rear leg 2 has a rear connecting seat 4 at its upper end. The front connecting seat 3 is connected to the rear connecting seat 4 on the same side. A detachable seat 5 for sitting is provided between the two front connecting seats 3. A tray 7 can be detachably connected to the seat 5 for the child to eat while sitting in the seat 5. The tray can be removed when not in use. In this embodiment, the child chair also includes a support plate 9 provided on the front legs 1 and rear legs 2, and a protective frame 8 that can be connected to the front connecting seat 3 after the seat 5 is removed. The support plate 9 can be used to prevent objects from falling, and when the seat is removed, the child can stand on the support plate 9, which can be used as a stool. In addition, after the protective frame 8 is connected to the front connecting seat 3, children can stand on the support plate 9 to complete some learning activities, such as learning to wash vegetables and dishes in the kitchen. The protective frame 8 serves as a safety protection.
[0034] like Figures 5 to 10As shown, a locking mechanism 6 is provided between the seat 5 and the front connecting seat 3. The locking mechanism 6 includes a locking slot 61 on the seat 5. The front connecting seat 3 has a locking pin 62 that can slide within it and engage or disengage with the locking slot 61. The front connecting seat 3 has an operating block 63 that can slide relative to it and drive the locking pin 62 to disengage from the locking slot 61. An unlocking retaining component 64 is provided between the operating block 63 and the front connecting seat 3, which can keep the locking mechanism 6 unlocked after the operating block 63 drives the locking pin 62 to disengage from the locking slot 61. The unlocking retaining component 64 has a mating part 65 that can be pushed by the seat 5 when the seat 5 is removed. The front connecting seat 3 has an elastic element 66 that can push the operating block 63 and the locking pin 62 back to their original positions when the seat 5 pushes the mating part 65. When seat 5 needs to be removed, simply press and slide the operating block 63. The operating block 63 will drive the latch 62 to disengage from the latch 61 on seat 5, thus unlocking seat 5 from front connecting seat 3. During the sliding process of the operating block 63, the unlocking retaining component 64 can maintain the unlocked state of seat 5 and front connecting seat 3, eliminating the need for the user to continuously press the operating block 63. Therefore, after pressing the operating block 63, the user can free their hand to lift seat 5, making the removal of seat 5 easier. Moreover, when seat 5 is removed, seat 5 will push the mating part 65 on the unlocking retaining component 64, thereby moving the unlocking retaining component 64. After the unlocking retaining component 64 moves, the elastic element 66 will push the operating block 63 and latch 62 to slide back to their initial state. After seat 5 is removed, the guard frame 8 can be connected to the front connecting seat 3. In this embodiment, the guard frame 8 includes an annular frame 81, with connecting parts 82 on both sides of the frame 81. The connecting parts 82 are provided with locking holes 83 that can engage or disengage with the latch 62.
[0035] like Figure 9 and Figure 10 As shown, the elastic element 66 includes a first return spring 661 disposed between the front connecting seat 3 and the locking pin 62, which can push the locking pin 62 to move, and a second return spring 662 disposed between the front connecting seat 3 and the operating block 63, which can push the operating block 63 to reset.
[0036] like Figures 8 to 10As shown, the unlocking and holding assembly 64 includes a locking block 641 slidably disposed within the operating block 63. The front connecting seat 3 is provided with a locking hole 642 that can engage with the locking block 641 and prevent the operating block 63 from resetting when the operating block 63 moves to unlock. A second spring 643 is provided between the locking block 641 and the operating block 63, which can push the locking block 641 out and lock it into the locking hole 642 when the locking block 641 is aligned with the locking hole 642. The mating part 65 is an inclined surface disposed on the lower side of the locking block 641 and can be pushed by the seat 5 when the seat 5 is removed, causing the locking block 641 to slide into the operating block 63. When the operating block 63 is pressed and slid, the operating block 63 drives the locking pin 62 to disengage from the locking position 61 on the seat 5 or the locking hole 83 on the guard frame 8. During the sliding process of the operating block 63, when the locking block 641 is aligned with the locking hole 642, the second spring 643 pushes the locking block 641 into the locking hole 642. At this time, the operating block 63 cannot be reset, thus maintaining the disengaged state of the locking pin 62 from the locking position 61 or the locking hole 83. When the seat 5 or the guard frame 8 is lifted upward, the seat 5 or the guard frame 8 pushes the mating part 65, causing the locking block 641 to move into the operating block 63. Since the mating part 65 is an inclined surface, after the locking block 641 moves inward a certain distance, the second reset spring 662 can push the operating block 63 to slide and reset. At this time, the first reset spring 661 pushes the locking pin 62 to move and reset.
[0037] like Figures 11 to 13 As shown, the front connecting seat 3 and the rear connecting seat 4 are rotatably connected. A crossbar 10 is provided between the two rear support legs 2. The front side of the bearing plate 9 is rotatably connected to the middle of the two front support legs 1. A linkage rod 11 is provided between the middle of the bearing plate 9 and the crossbar 10, which is rotatably connected to both. A locking assembly 12 is provided between the rear side of the bearing plate 9 and the crossbar 10. When the front support legs 1 rotate and fold relative to the rear support legs 2, the rear side of the bearing plate 9 moves to a position close to the front connecting seat 3. After the seat 5 and the guard frame 8 are removed, the front support leg 1 and the rear support leg 2 can rotate relative to each other. At this time, the support plate 9 rotates relative to the front support leg 1, and the linkage rod 11 rotates relative to the rear support leg 2 and the support plate 9. This causes the rear side of the support plate 9 to move closer to the front connecting seat 3. Finally, the front support leg 1, the rear support leg 2, the support plate 9 and the linkage rod 10 come together and are folded for easy storage. In the unfolded state, the rear side of the support plate 9 can also rest on the crossbar 10 to make the child chair have a strong load-bearing capacity.
[0038] like Figure 11As shown, the locking assembly 12 includes a sliding block 121 that can slide relative to the support plate 9. The sliding block 121 is provided with a latch 122 that can lock or disengage from the crossbar 10 when it slides. A third spring (not shown in the figure) is provided between the sliding block 121 and the support plate 9 to push the sliding block 121 back to its original position. When folding is required, simply pull the sliding block 121. Once the latch 122 disengages from the crossbar 10, the support plate 9 can be rotated to fold the child chair with the seat 5 and guard frame 8 removed, so that it can be stored or placed in the trunk of a car for travel.
[0039] like Figure 12 As shown, the latch 122 is provided with an inclined wall 123 that can press against the crossbar 10 and cause the sliding block 121 to slide when the front support leg 1 and the rear support leg 2 are deployed. When deployed, pressing the bearing plate 9 will cause the inclined wall 123 to press against the crossbar 10, at which time the sliding block 121 will slide. Once the latch 122 moves below the crossbar 10, the third spring will push the sliding block 121 to reset, and the latch 122 will lock the crossbar 10 again to maintain the deployed state.
[0040] like Figure 1 As shown, the front support leg 1 is also equipped with a foot pedal 13, which allows children to place their feet on the foot pedal 13 when sitting on the support plate 9, thus ensuring a comfortable ride.
[0041] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
