[0025] As shown in the accompanying drawings, a children's dining chair includes a chair frame 1 having an unfolded position and a folded position, and a detachable seat accessory 2.

[0026] The chair frame 1 comprises side supports 11 on either side, and a seat frame 12 positioned between the side supports 11 in a closed, frame-like configuration. The seat attachment 2 is removably attached to the upper portions of the side supports 11 on either side of the chair frame 1. When assembled and in use, the seat attachment 2 forms a child-friendly seating space between the seat attachment 2 and the seat frame 12, effectively dividing a traditional one-piece seat into two components: the seat frame and the seat attachment. After removal, the seat attachment 2 and the chair frame 1 fold together, creating a flatter and more compact packaging.

[0027] The detailed structure is as follows:

[0028] In this embodiment, each side support 11 includes a front support a, a rear support b pivotally connected to the upper end of the front support a about a first axis X1, a first strut c, and a second strut d. The rear end of the first strut c is pivotally connected to the rear support b about a third axis X3, the front end of the second strut d is pivotally connected to the front support a about a second axis X2, and the front end of the first strut c is pivotally connected to the rear end of the second strut d about a fourth axis X4. In other words, the front support a, rear support b, and the first and second struts c and d on each side form a four-bar linkage. A chair frame locking mechanism is provided at the pivotal connection between the first and second struts d. When locked, the chair frame locking mechanism on each side forms a triangular mechanism with the front and rear supports a and b, resulting in a simple structure and stability in the deployed position.

[0029] A seat front pedal 13 is provided between the second support rod d on both sides. The seat front pedal 13 is positioned at the front lower portion of the seat frame 12 for stepping on by the child. The rear support b lower end on both sides is connected to form an integral body by a bottom crossbar.

[0030] In this embodiment, as shown in the attached Figure 4-6 As shown, an unlocking control mechanism is provided on the front pedal 13 of the seat. The unlocking control mechanism includes a button that is slidably or rotatably provided on the front side of the front pedal 13 of the seat, and two traction cables that are respectively provided between the unlocking control mechanism and the corresponding chair frame locking mechanism. By pressing the button, the traction cables on both sides are driven to control the unlocking of the chair frame locking mechanisms on both sides. The unlocking control is convenient. After unlocking, the fourth axis X4 moves downward, and the front bracket a and the rear bracket b on each side are folded together front and back, and the chair frame 1 is folded. The specific chair frame locking mechanism and unlocking control mechanism are not the key points of the invention of this solution. There are many existing mechanisms. As long as the mechanism unlocks the locking joint by controlling the rotation of the locking joint through a button or a traction cable, it can be applied here. For example, the control mechanism on the handle of the baby stroller with patent publication number CN2333603Y. For example, the locking mechanism and unlocking operating mechanism of the child stroller with patent publication number CN201062044Y.

[0031] In this embodiment, as shown in the attached Figure 1 、 3As shown in Figures 4 and 5, the seat frame 12 is pivotally connected between the side supports 11. The two sides of the seat frame 12 are pivotally connected to the corresponding front supports a about the fifth axis X5. This means that the seat attachment 2 is detachably connected to the chair frame 1. The seat frame 12 is independently pivotally mounted on the chair frame 1 and folds and unfolds with the chair frame. When the chair frame 1 is in the unfolded position, the seat frame 12 is stabilized by a stabilizing mechanism. In this embodiment, the stabilizing mechanism is relatively simple, comprising a shelf block b1 fixed to the upper portion of each rear support b. When the chair frame 1 is in the unfolded position, the front and rear supports a and b are spread apart, and the seat frame 12 presses against the shelf blocks b1 on both sides, maintaining its position. The shelf blocks b1 can also be mounted directly on the front support a. Alternatively, other locking mechanisms can be used to prevent the seat frame 12 from rotating about the fifth axis X5. The seat frame 12 can be detachably mounted with a seat plate or a removable seat layer. When the chair frame 1 is folded, the rear portion of the seat frame 12 can be directly rotated upwards to disengage it from the shelf block b1 and fold it relative to the front support a.

[0032] As attached Figure 1 、 2 As shown in FIG4-6, after the seat accessory 2 is installed between the upper portions of the side brackets 11 on both sides, the seat accessory 2 is located above the seat frame 12. After assembly, when in use, the seat accessory 2 forms a protective covering above the seat frame 12. Figure 3 As shown, the seat accessory 2 includes an inverted U-shaped backrest frame 22 and two side armrest frames 21. Each side armrest frame 21 includes a side armrest mounting pipe and armrest side panels fixed to the side armrest mounting pipe. The two armrest side panels are designed to be mounted above the left and right sides of the seat frame 12. The lower portion of the side armrest mounting pipe is detachably connected to the upper portion of the front bracket a, while the upper portion of the side armrest mounting pipe is detachably connected to the backrest side rods of the backrest frame 22. Various methods exist for detachably connecting the backrest frame 22 to the side armrest frames 21, and between the side armrest frames 21 and the front bracket a. In this embodiment, the simplest and most convenient method is to use a spring-loaded locking method using a pipe insert. For example, the lower portion of the side armrest mounting pipe is locked to the corresponding front bracket a by inserting the pipe and positioning the spring-loaded pin in a locking hole. Disassembly is achieved by withdrawing the spring-loaded pin and pulling the pipe apart.

[0033] The seat accessory 2 also includes a dining tray 23, which can be installed between the upper edges of the two armrest side panels in an adjustable front-to-back position. The upper edges of the armrest side panels on each side are respectively provided with multiple mounting grooves along the front-to-back direction. Locking teeth are elastically slidably provided on both sides of the dining tray 23. After pressing the two locking teeth, they are facing the mounting grooves at the corresponding positions, and the locking teeth are released. Under the action of elasticity, the locking teeth are reset, and then inserted into the mounting grooves to cooperate, that is, the gear position is fixed and the position of the dining tray is fixed.

[0034] A seat pocket made of flexible fabric (not shown) is connected between the armrests 21. The seat pocket comprises a seat layer positioned above the seat frame 12 during use, a backrest layer whose lower edge is secured to the rear edge of the seat layer, and left and right side panels connected between the seat and backrest layers. During packing, the flexible seat pocket remains connected between the armrests 21, maintaining the ability to fold the armrests 21 relative to each other. However, it provides additional safety and comfort for the child when in the unfolded position.

[0035] When folding and packing the children's dining chair for storage or transportation, the two side armrests 21 are removed from the front frame a. The dining tray 23, two armrests 21, and backrest 22 of the seat accessory 2 are then separated and packed together with the folded chair frame 1. The seat accessory 2 is placed between the folded chair frames 1 and packed together. This packaged volume is flatter and smaller than that of commercially available dining chairs, requiring less storage space, making it easier to transport or store and significantly reducing transportation costs. To further reduce the packaged volume, the front frame a and rear frame b can be disconnected and rotated or split to further reduce the folded height. Because the seat accessory 2 and chair frame 1 are detachably connected, there are fewer interfering or interfering rods between them compared to other commercially available dining chairs, resulting in a simpler design when unfolded.

[0036] To enhance the rigidity between the two side brackets, the chair frame 1 also includes at least one transversely extending crossbar, such as the bottom crossbar between the bottoms of the two rear brackets b in this embodiment. In addition, the front seat footboard 13 and the frame-shaped seat frame 12 can also be considered crossbars to ensure rigidity between the left and right sides of the chair frame.

[0037] In this embodiment, the seat is divided into a seat frame 12 and a seat accessory 2. The seat frame 12 is separately arranged on the chair frame 1, and the seat accessory 2 is removable. In addition to the side brackets of the four-bar mechanism in this embodiment, the chair frame structure can also adopt a children's dining chair frame as disclosed in the authorization publication number CN206381002U, and a folding support frame structure as disclosed in the authorization publication number CN212185905U.

[0038] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications made within the spirit of the main technical solution of the present invention are intended to be included within the scope of protection of the present invention.
