Description

Technical Field

[0001] This utility model belongs to the field of children's dining chair technology, and relates to a folding bracket and a children's dining chair. Background Technology

[0002] Currently, most children's high chairs are only designed for children to sit, and there is no device for children to stand. Some children like to eat standing up, but the table is not high enough for them, so they still need a footrest to elevate their feet.

[0003] Therefore, some children's dining chairs have appeared on the market, with a standing board installed on the table leg support and the chair part is detachably connected to the support. The chair part can be installed on the support according to actual needs. However, this kind of table leg support with a standing board cannot be folded, takes up a lot of space, and has a lot of room for improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a folding bracket and a children's dining chair.

[0005] The objective of this utility model can be achieved through the following technical solution: a folding bracket, comprising:

[0006] The first leg has a first rotating part and a second rotating part respectively provided at both ends;

[0007] The second leg has a third rotating part and a fourth rotating part at its two ends, and the third rotating part is rotatably connected to the first rotating part.

[0008] A standing assembly includes a standing plate and a linkage frame. The standing plate is provided with a fifth rotating part and a sixth rotating part. The fifth rotating part is rotatably connected to a second rotating part. The linkage frame is provided with a seventh rotating part and an eighth rotating part. The seventh rotating part is rotatably connected to a fourth rotating part, and the eighth rotating part is rotatably connected to the sixth rotating part.

[0009] In the aforementioned folding bracket, the fifth rotating part is disposed at one end of the standing plate, the sixth rotating part is disposed in the middle of the standing plate, and a limiting part is disposed at the other end of the standing plate, the limiting part being able to contact the fourth rotating part.

[0010] In the aforementioned folding bracket, the second rotating part is configured as a first rotating column, the fifth rotating part is configured as a first rotating seat, the first rotating seat is provided with a first rotating hole, and the first rotating column passes through the first rotating hole.

[0011] In the aforementioned folding bracket, the fourth rotating part is configured as a second rotating column, the seventh rotating part is configured as a second rotating seat, the second rotating seat is provided with a second rotating hole, and the second rotating column passes through the second rotating hole.

[0012] In one of the folding brackets described above, a locking component is also included. The locking component is connected to the standing plate. When the limiting part contacts the second rotating column, the locking component is used to lock the second rotating column.

[0013] In one of the folding brackets described above, the locking assembly includes a fixed base and a locking block. The fixed base is connected to the standing plate and has a locking hole. The locking block is disposed within the fixed base and can move relative to the fixed base. The locking block can extend out of or retract from the locking hole. When the locking block extends out of the locking hole, a locking space is formed between the locking block and the standing plate to restrict the movement of the second rotating column.

[0014] In one of the folding brackets described above, the locking assembly further includes a return spring, the two ends of which are in contact with the fixed base and the locking block, respectively, and the return spring drives the locking block to move away from the fixed base.

[0015] In the aforementioned folding bracket, the fixing seat is provided with a limiting groove, the locking block is provided with a limiting block, and the limiting block is located in the limiting groove and can contact both sides of the limiting groove.

[0016] In the aforementioned folding bracket, the linkage frame has a U-shaped structure, the sixth rotating part is configured as the third rotating seat, the eighth rotating part is configured as the middle part of the linkage frame, and the seventh rotating part is provided at both ends of the linkage frame.

[0017] Secondly, a children's dining chair, including the aforementioned folding support.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the folding bracket forms a foldable support frame through a multi-link rotating connection structure of the first leg, the second leg and the standing component. It can not only serve as a support base for children's dining chairs, but also provide a stable platform for the standing board when unfolded, realizing universal support for the bracket in both "sitting" and "standing" modes. The structure is compact and highly reliable. The fifth rotating part is located at one end of the standing plate, the sixth rotating part is located in the middle, and the other end is provided with a limiting part. This asymmetrical layout allows the limiting part to contact the fourth rotating part during the unfolding process of the bracket, achieving automatic positioning and limiting. This ensures that the bracket forms a stable mechanical structure after it is fully unfolded, preventing load-bearing failure due to incomplete positioning. It is particularly suitable for use scenarios that require long-term support of a child's standing weight. The locking component cooperates with the fixing seat through the locking block, forming a locking space with the standing plate when extended, firmly limiting the second rotating column, thereby achieving quick locking without additional operation, suitable for parents to operate with one hand. The reset spring drives the locking block to automatically pop out, achieving a default locked state. Users do not need to manually lock after unfolding the bracket, freeing their hands to use it. When folding, only the locking block needs to be manually unlocked to prevent safety hazards caused by forgetting to lock. Attached Figure Description

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0033] like Figures 1-6 As shown, a folding support includes: a first leg body 100, a second leg body 200, and a standing component 300.

[0034] The first leg body 100 is provided with a first rotating part 110 and a second rotating part at its two ends, respectively.

[0035] The second leg body 200 is provided with a third rotating part 210 and a fourth rotating part at its two ends, respectively, and the third rotating part 210 is rotatably connected to the first rotating part 110.

[0036] The standing assembly 300 includes a standing plate 310 and a linkage frame 320. The standing plate 310 is provided with a fifth rotating part and a sixth rotating part. The fifth rotating part is rotatably connected to the second rotating part. The linkage frame 320 is provided with a seventh rotating part and an eighth rotating part 322. The seventh rotating part is rotatably connected to the fourth rotating part, and the eighth rotating part 322 is rotatably connected to the sixth rotating part.

[0037] In this embodiment, the folding bracket forms a foldable support frame through a multi-link rotating connection structure of the first leg 100, the second leg 200 and the standing component 300. It can not only serve as a support base for a children's dining chair, but also provide a stable platform for the standing board 310 when unfolded, realizing universal support for the bracket in both "sitting" and "standing" modes. The structure is compact and highly reliable.

[0038] like Figures 1-6 As shown, based on the above embodiment, the fifth rotating part is disposed at one end of the standing plate 310, the sixth rotating part is disposed at the middle of the standing plate 310, and the other end of the standing plate 310 is provided with a limiting part 313 (not shown in the figure), which can contact the fourth rotating part.

[0039] In this embodiment, the fifth rotating part is located at one end of the standing plate 310, the sixth rotating part is located in the middle, and the other end is provided with a limiting part 313. This asymmetrical layout achieves automatic positioning and limiting by the limiting part 313 contacting the fourth rotating part during the deployment of the support, ensuring that the support forms a stable mechanical structure after it is fully deployed, preventing load-bearing failure due to failure to position, and is particularly suitable for use scenarios that require long-term support of a child's standing weight.

[0040] like Figures 1-6 As shown, based on the above embodiment, the second rotating part is configured as a first rotating column 120, and the fifth rotating part is configured as a first rotating seat 311. The first rotating seat 311 is provided with a first rotating hole (not shown in the figure), and the first rotating column 120 passes through the first rotating hole.

[0041] In this embodiment, the second rotating part is configured as the first rotating column 120, and the fifth rotating part is configured as the first rotating seat 311 with the first rotating hole. The column hole through-connection method has a simple structure, smooth rotation, and firm connection. It can still maintain high coaxiality and low wear during frequent folding and use, ensuring the stability of the bracket in a long-term standing support state.

[0042] like Figures 1-6 As shown, based on the above embodiment, the fourth rotating part is configured as a second rotating column 220, the seventh rotating part is configured as a second rotating seat 321, the second rotating seat 321 is provided with a second rotating hole (not shown in the figure), and the second rotating column 220 passes through the second rotating hole.

[0043] In this embodiment, the fourth rotating part is configured as the second rotating seat 321, and the seventh rotating part is configured as the second rotating seat 321 with the second rotating hole. The column hole through-connection method has a simple structure, smooth rotation, and firm connection. It can still maintain high coaxiality and low wear during frequent folding and use, ensuring the stability of the bracket in a long-term standing support state.

[0044] like Figures 1-6 As shown, based on the above embodiment, a locking component 400 is also included. The locking component 400 is connected to the standing plate 310. When the limiting part 313 contacts the second rotating column 220, the locking component 400 is used to lock the second rotating column 220.

[0045] In this embodiment, when the limiting part 313 contacts the second rotating column 220, the locking component 400 can lock the second rotating column 220 to ensure that the bracket will not be accidentally folded when supporting a child standing, greatly improving the safety of use and avoiding the risk of falling due to misoperation.

[0046] like Figures 1-6As shown, based on the above embodiment, the locking assembly 400 includes a fixed base 410 and a locking block 420. The fixed base 410 is connected to the standing plate 310. The fixed base 410 is provided with a locking hole (not shown in the figure). The locking block 420 is disposed in the fixed base 410 and can move relative to the fixed base 410. The locking block 420 can extend or retract from the locking hole. When the locking block 420 extends out of the locking hole, a locking space is formed between it and the standing plate 310 to restrict the movement of the second rotating column 220.

[0047] In this embodiment, the locking component 400 cooperates with the fixing base 410 through the locking block 420, and forms a locking space with the standing plate 310 when extended, which firmly limits the second rotating column 220, thereby achieving quick locking without additional operation and suitable for parents to operate with one hand.

[0048] like Figures 1-6 As shown, based on the above embodiment, the locking assembly 400 further includes a return spring 430. The two ends of the return spring 430 are in contact with the fixed base 410 and the locking block 420, respectively. The return spring 430 drives the locking block 420 to move away from the fixed base 410.

[0049] In this embodiment, the reset spring 430 drives the locking block 420 to pop out automatically, achieving a default locked state. After unfolding the bracket, the user does not need to manually lock it and can use it with their hands free. When folding, the user only needs to manually unlock the locking block 420 to prevent safety hazards caused by forgetting to lock it.

[0050] like Figures 1-6 As shown, based on the above embodiment, the fixing seat 410 is provided with a limiting groove 411, the locking block 420 is provided with a limiting block 421, and the limiting block 421 is located in the limiting groove 411 and can contact both sides of the limiting groove 411.

[0051] In this embodiment, the limiting block 421 is located within the limiting groove 411 and can contact both sides of the limiting groove 411, thereby limiting the maximum travel of the locking block 420.

[0052] like Figures 1-6 As shown, based on the above embodiment, the linkage frame 320 has a U-shaped structure, the sixth rotating part is configured as the third rotating seat 312, the eighth rotating part 322 is configured as the middle part of the linkage frame 320, and the seventh rotating part is provided at both ends of the linkage frame 320.

[0053] In this embodiment, the linkage frame 320 has a U-shaped structure with seventh rotating parts at both ends and an eighth rotating part 322 in the middle, forming a symmetrical support layout, which not only improves the overall rigidity but also evenly distributes the force it receives.

[0054] like Figures 1-7 As shown, a children's dining chair includes the aforementioned folding support.

[0055] like Figures 1-7 As shown, the overall working principle of this children's high chair is as follows:

[0056] When the user unfolds the folding bracket from its stored state, force is applied to the first leg 100 and the second leg 200, causing them to unfold outward. The first rotating part 110 at one end of the first leg 100 and the third rotating part 210 at one end of the second leg 200 are rotatably connected to form an X-shaped cross-hinged structure, which serves as the folding core of the entire bracket.

[0057] As the legs extend, the second rotating part (i.e., the first rotating column 120) at the other end of the first leg 100 rotates relative to the fifth rotating part (i.e., the first rotating seat 311) on the standing plate 310; at the same time, the fourth rotating part (i.e., the second rotating column 220) at the other end of the second leg 200 rotates relative to the seventh rotating part (i.e., the second rotating seat 321) on the linkage frame 320.

[0058] The linkage frame 320 has a U-shaped structure with a seventh rotating part at each end and an eighth rotating part 322 in the middle. The eighth rotating part 322 is rotatably connected to the sixth rotating part (i.e. the third rotating seat 312) on the standing plate 310 to form a closed-loop four-bar linkage mechanism. This mechanism moves synchronously during the unfolding process, causing the standing plate 310 to gradually rise and tend to be horizontal, ultimately forming a stable support platform.

[0059] When the support is fully extended to the use position, the limiting part 313 at the far end of the standing plate 310 contacts the fourth rotating part (i.e., the second rotating column 220) of the second leg 200, forming a mechanical stop, indicating that the support has reached a stable state of full extension. At this time, the locking component 400 provided on the standing plate 310 is triggered: the locking component 400 includes a fixed base 410 and a locking block 420. The fixed base 410 is connected to the standing plate 310, and the locking block 420 is disposed in the fixed base 410 and can be extended and retracted; under the action of the return spring 430, the locking block 420 is pushed to move away from the fixed base 410, thereby automatically extending out of the locking hole of the fixed base 410.

[0060] When the locking block 420 is fully extended, it forms a locking space with the standing plate 310, which securely restricts the second rotating column 220 (i.e. the fourth rotating part) within the space, achieving automatic locking. This locking mechanism does not require additional operation from the user. As long as the bracket is fully extended, it will automatically lock, effectively preventing accidental folding caused by force or accidental contact during use by children (especially when standing to eat), and greatly improving safety.

[0061] In its unfolded and locked state, the folding bracket can be used as the base of a children's high chair: users can install the seat assembly as needed for children to sit while eating; or remove the seat and allow children to stand while eating via the standing board 310.

[0062] When storage is required, the user only needs to manually unlock the locking block 420 to overcome the elastic force of the return spring 430, causing it to retract into the locking hole and release the restriction on the second rotating column 220; then the first leg body 100 and the second leg body 200 are folded inward, and the linkage frame 320 and the standing plate 310 are folded accordingly, and the overall structure is compact and easy to store and carry.
