[0002] A chair is a piece of furniture that allows people to sit and rest. It is widely found in people's living spaces. However, common chairs are generally large and not suitable for small children. Therefore, children's chairs specifically designed for children have begun to be sold on the market.

[0003] Common children's chairs, designed to accommodate children's needs, not only provide basic support but also include a barrier structure that works in conjunction with the backrest to enclose the seat and prevent falls and injuries, especially for infants. However, as children grow, their bodies may not be suited to adult chairs, and the restrictive structure at the front of the chair can hinder their use. Furthermore, most children's chairs have fixed, non-adjustable designs, requiring the purchase of new chairs, which is inconvenient. Additionally, the fixed height of these chairs means they cannot be adjusted to accommodate the child's height and needs, causing inconvenience in practice. Finally, children's chairs generally offer limited functionality and are not very flexible in their use. Utility Model Content

[0030] Please see Figure 1-5 A retractable chair for children includes a leg frame 1, a seat 2 on the leg frame 1, a backrest 3 at one end of the seat 2 and a restraint frame 4 at the other end, armrest frames 5 on both sides of the seat 2, the backrest 3, the restraint frame 4 and the armrest frames 5 all rotatingly engaging with the seat 2, a fixing block 6 on the armrest frame 5, a fixing slot 7 on both the backrest 3 and the restraint frame 4, the fixing block 6 engaging with the fixing slot 7, a restraining slider 8 slidably connected in the fixing slot 7, a restraining groove 9 on the fixing block 6, and the restraining slider 8 engaging with the restraining groove 9;

[0031] The lower end of the leg frame 1 is slidably connected to a telescopic leg 10. The telescopic leg 10 has a positioning hole 11. Multiple positioning holes 11 are provided and arranged at equal intervals. The leg frame 1 is provided with a positioning bolt 12, which cooperates with the leg frame 1 and the positioning hole 11.

[0032] In this embodiment, the leg support 1 provides support for the seat 2 so that children can sit and rest. Depending on usage needs, the restraint frame 4, armrests, and backrest 3 can be unfolded to form a fence structure. The armrest frame 5 is inserted into the corresponding fixed slots 7 of the restraint frame 4 and backrest 3 via fixed inserts 6. The restraint slider 8 is moved so that its front end is inserted into the restraint groove 9, thereby limiting the position of the restraint groove 9 and fixing the fixed inserts 6 in the fixed slots 7. This fixes the positions of the restraint frame 4, armrests, and backrest 3, protecting the child around the seat. For changes in needs, the above steps can be reversed to remove the restraint frame 4 and tilt the front enclosure, making it easier for older children to use.

[0033] More specifically, according to usage requirements, the applicable height of the equipment is adjusted by loosening the positioning bolt 12, causing it to leave the corresponding positioning hole 11 and releasing the restriction on the telescopic leg 10. Then, the telescopic leg 10 is slid along the leg clamp to adjust its extension length. Once the desired position is reached, the positioning bolt 12 is tightened again, causing it to insert into the corresponding positioning hole 11 and restrict the telescopic leg 10. The cooperation between the telescopic leg 10 and the leg frame 1 supports the seat surface 2, keeping it at a suitable height to meet the user's height requirements.

[0034] Please see Figure 1and Figure 5 As one implementation of the tabletop switching method: one end of the limiting frame 4 is rotatably connected to the chair surface 2, and the other end is rotatably connected to the tabletop 13. The lower end of the tabletop 13 is provided with a rotating groove 14, and a support column 15 is rotatably connected in the rotating groove 14. The limiting frame 4 is provided with a support slot 16, and the support column 15 cooperates with the support slot 16.

[0035] Specifically, when infants and young children need to eat, in addition to restricting and protecting them with the restraint frame 4, the tabletop 13 can be rotated and unfolded so that the support column 15 inside the rotating slot 14 can be rotated out. Then, the movable end of the support column 15 is inserted into the support slot 16, thereby supporting the tabletop 13 through the support column 15, so that the tabletop 13 and the restraint frame 4 are vertically distributed and cooperate to provide a tabletop support structure for placing tableware and food.

[0036] Please see Figure 5 As a further embodiment of the support slot: the lower end of the support slot 16 is provided with a limiting inclined block 17, and the movable end of the support column 15 is provided with a fitting inclined surface 18, which cooperates with the limiting inclined block 17.

[0037] Specifically, by restricting the engagement between the inclined block 17 and the mating inclined surface 18, the insertion is made more stable, preventing the support column 15 from sliding out of the support slot 16.

[0038] Please see Figure 5 As a further embodiment of the tabletop: a first magnet 19 is provided on the side end of the limiting frame 4, and a second magnet 20 is provided on the inner side of the tabletop 13, with the first magnet 19 and the second magnet 20 cooperating.

[0039] Specifically, when the tabletop 13 is stored, the tabletop 13 is made to fit tightly against the restraint frame 4 by the cooperation of the first magnet 19 and the second magnet 20.

[0040] Please see Figures 3-5 As a further embodiment of the limiting slider: both the backrest 3 and the limiting frame 4 are provided with control blocks 21, which cooperate with the limiting slider 8, and the limiting slider 8 is provided with a pressure spring 22 between it and the inner wall of the fixing slot 7.

[0041] Specifically, the movement of the limiting slider 8 is controlled by the control block 21 for easy operation, and the pressure spring 22 applies pressure to the limiting slider 8 to keep it stable when it is engaged with the fixed plug 6.

[0042] Please see Figures 2-4 As a further embodiment of the chair back: the chair back 3 is provided with a storage groove 23, the storage groove 23 cooperates with the armrest frame 5, the storage groove 23 is provided with a storage opening 24, and the storage opening 24 cooperates with the fixing block 6.

[0043] Specifically, when storing the equipment, the backrest 3 is placed on the seat 2, and then the armrest 5 is rotated into the storage slot 23. The space provided by the storage opening 24 accommodates the fixing block 6, avoiding interference between the structures.

[0044] Please see Figure 1 As a further embodiment of the leg clamp: a reinforcing frame 25 is provided between the leg frames 1.

[0045] Specifically, the reinforcement frame 25 forms a support structure between the legs 1 to improve the structural strength.

[0046] Please see Figure 1 As a further embodiment of the telescopic leg: the lower end of the telescopic leg 10 is provided with a wheel frame 26, and the wheel frame 26 is provided with a support wheel 27.

[0047] Specifically, the wheel frame 26 is used to connect the support wheel 27 to the ground, supporting the equipment and making it easy to move the child chair.

[0048] In summary, when the overall equipment is in use (or running):

[0049] When in use, the leg frame 1 supports the device, and the reinforcing frame 25 forms a support structure between the leg frames 1, increasing structural strength. This provides a support structure for the seat 2 for the child to sit on. The leg frame 1, through the wheel frame 26, allows the support wheels 27 to contact the ground, supporting the device and facilitating movement of the child chair. Depending on usage needs, the restraint frame 4, armrests, and backrest 3 can be unfolded to form a fence structure. The armrest frame 5 is inserted into the corresponding fixing slots 7 of the restraint frame 4 and backrest 3 via fixing blocks 6. The control block 21 controls the movement of the restraint slider 8, causing its front end to insert into the restraint groove 9, thereby restricting movement of the restraint groove. 9. Limiting is performed, and the pressure spring 22 applies pressure to the limiting slider 8, so that the limiting slider 8 remains stable when it cooperates with the fixed plug 6, fixing the fixed plug 6 in the fixed slot 7, thereby fixing the position of the limiting frame 4, armrest and backrest 3, protecting the child around the seat. Depending on the needs, the above steps can be reversed to remove the limiting frame 4 and tilt the front guardrail to make it easier for older children to use. Alternatively, the equipment can be completely stored by placing the backrest 3 on the seat 2 and then rotating the armrest frame 5 into the storage slot 23. The space provided by the storage opening 24 accommodates the fixed plug 6, avoiding interference between structures.

[0050] According to usage requirements, the applicable height of the equipment is adjusted by loosening the positioning bolt 12, disengaging it from the corresponding positioning hole 11, and releasing the restriction on the telescopic leg 10. Then, the telescopic leg 10 is slid along the leg clamp to adjust its extension length. After reaching the desired position, the positioning bolt 12 is tightened again, inserting it into the corresponding positioning hole 11 to restrict the telescopic leg 10. The cooperation between the telescopic leg 10 and the leg frame 1 supports the seat surface 2, ensuring it is at a suitable height to meet the user's height requirements. Furthermore, when infants and young children need to eat, in addition to using the restraint frame 4 to assist them... In addition to the restraint and protection, the tabletop 13 can be rotated and unfolded, allowing the support column 15 inside the rotating groove 14 to rotate out. Then, the movable end of the support column 15 is inserted into the support slot 16, thereby supporting the tabletop 13 through the support column 15. The engagement between the restraining inclined block 17 and the fitting inclined surface 18 makes the insertion more stable, preventing the support column 15 from sliding out of the support slot 16. This allows the tabletop 13 and the restraint frame 4 to be vertically distributed and engaged, providing a tabletop support structure for placing tableware and food. Furthermore, when the tabletop 13 is stored, the engagement of the first magnet 19 and the second magnet 20 keeps the tabletop 13 close to the restraint frame 4, preventing it from unfolding due to gravity.
