Abstract
Description
Technical Field
[0001] This utility model relates to the field of dining chair technology, and in particular to a children's dining chair. Background Technology
[0002] A children's high chair is a commonly used children's product. Its main structure includes a seat and a support component located under the seat. It is also equipped with a footrest and a backrest, which are also mounted on the support component.
[0003] Most children's high chairs currently in use are fixed-type. Their structural design is usually focused on meeting the basic needs of children in a specific age group. The seat height, footrest height, and backrest position are all relatively fixed to the support components and cannot be adjusted. This presents the following problems during use: Children are in a period of rapid physical development during infancy and preschool, and their height changes significantly. If a fixed-type high chair is used during this growth process, the relatively fixed position of the seat and footrest will prevent the feet from reaching the footrest or the legs from stretching naturally. The fixed seat height will cause children to sit too high as they grow taller, and the relatively fixed position of the backrest and seat will only allow them to sit on part of the seat. All of these factors directly reduce the safety and comfort of the high chair, requiring frequent replacements as the child grows, increasing living costs, shortening the actual lifespan of the high chair, and wasting resources.
[0004] Although some dining chairs on the market have height-adjustable functions, they only adjust the height of the seat, while the footrest and backrest are fixed in position, which will also affect the comfort during use. Utility Model Content
[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a children's dining chair that can adjust the height of the seat, footrest and backrest to improve the comfort during use and extend the actual service life.

[0025] like Figure 1-7 As shown, a children's dining chair includes a seat frame, a seat board 1, a footrest 2, and a backrest 3, with a seat cushion 4 fixedly installed on the seat board; The seat frame includes two symmetrically arranged support frames. Each support frame includes a support plate 5 and support legs 6 fixedly installed on both sides of the lower end of the support plate. The lower ends of the two support legs are inclined in a direction away from each other. The corresponding support legs of the two support frames are fixedly connected by a connecting rod 7. The lower end of the foot pedal is fixedly installed with a lower connecting block 8, and both ends of the lower connecting block are fixedly connected to the support leg through the pedal position adjustment structure; both sides of the seat are fixedly installed downwards with side connecting blocks 9, and both ends of the side connecting blocks are fixedly connected to the two support legs of the support frame through the seat position adjustment structure; both sides of the lower end of the backrest are provided with two threaded holes 10, and the support plate is fixedly provided with a support arm 11 to the rear. The support arm is provided with two rows of countersunk holes 12 arranged in a vertical direction, and the countersunk bolts 13 pass through the countersunk holes and are connected to the threaded holes.
[0026] In this way, the two symmetrically arranged support frames and outward-sloping support legs, combined with the connecting rods, significantly improve the overall stability and anti-tipping ability of the high chair, ensuring the safety of children when using it. The height of the support plate is higher than the height of the seat cushion, which plays a certain role in blocking and limiting the movement, thus improving the safety of children when using it.
[0027] The footrest's height is adjusted on the support legs via a lower connecting block and a footrest position adjustment structure; the seat's height is adjusted on the support legs via a side connecting block and a seat position adjustment structure; and the backrest's height is adjusted via an array of countersunk holes and countersunk bolts. These adjustment mechanisms work together to allow the high chair to adapt to the height, leg length, and seat depth requirements of children at different growth stages. This solves the core problems of previous technologies, such as fixed chair sizes, inability to adjust to children's growth, short lifespan, and waste, significantly improving the chair's applicability and lifespan. The use of countersunk bolts also prevents the bolt heads from protruding, reducing the risk of children bumping into them and enhancing safety.
[0028] Specifically, the backrest can be tilted, and the two threaded holes on one side of the backrest can be connected to one countersunk hole in each column, improving comfort. Alternatively, the backrest can be installed vertically, with the two threaded holes on one side connecting to two countersunk holes in each column.
[0029] In implementation, the pedal position adjustment structure includes a rectangular insert 14, the support leg has several rectangular holes 15 along its length that allow the insert to pass through, the end of the lower connecting block has a socket 16 for insertion and engagement with the insert, the lower connecting block also has an internal threaded hole 17 communicating with the socket, when the inner end of the insert is inserted into the socket and abuts against the bottom of the socket, the outer end of the insert is located in the rectangular hole, the insert has a clearance hole 18 through the internal threaded hole, a washer is fitted on the pedal locking bolt 19, the pedal locking bolt passes through the clearance hole and connects to the internal threaded hole, and the size of the washer is larger than the size of the rectangular hole.
[0030] In this way, the pedal position adjustment structure, through the engagement of the insert block with rectangular holes at different positions on the support leg, achieves multi-level adjustment of the pedal height, which can accurately adapt to the leg length of children at different growth stages, preventing children's legs from dangling or curling up; the insertion and engagement of the insert block with the lower connecting block and the bolt locking structure ensure the stability of the pedal after adjustment, preventing loosening and displacement during use; the setting of the shim further enhances the locking effect, and the structure is simple and easy to operate, making it convenient for parents to quickly adjust.
[0031] Specifically, insert the insert block through the rectangular hole and into the socket, with the outer end of the insert block inside the rectangular hole. Then, after fitting the washer onto the pedal locking bolt, pass it through the clearance hole and connect it to the internal threaded hole to fix the insert block inside the lower connecting block. When the position needs to be adjusted, remove the pedal position adjusting bolt, take out the insert block, and the foot pedal can be moved. Of course, when removing the insert block, the conical block can be pressed into the clearance hole of the insert block, so that the conical block and the insert block are pressed together, and when the conical block is taken out, it will move the insert block outward. Alternatively, when setting it, the size of the insert block can be smaller than the size of the rectangular hole, making it easier to clamp the insert block outward. Or, the support frame can be laid down, and the insert block can be placed downward, falling under its own weight.
[0032] In implementation, the seat position adjustment structure includes an elongated hole 20 in the side connecting block, a plurality of through holes 21 along the length of the support leg, a plurality of slots 23 for engaging nuts on both sides of the elongated hole, the nuts being hexagonal nuts and engaging the slots at both ends, a washer fitted on the seat locking bolt 24, the seat locking bolt passing through the through hole and being threaded to the nut, and the washer being larger than the through hole.
[0033] This design, with its slotted grooves on the side connecting block, reliably secures the hexagonal nut in advance, eliminating the need to hold the nut with hands or tools in confined spaces and preventing it from rotating with the bolt. This simplifies seat adjustment to a simple task: users only need to operate the seat locking bolts on the outside of the support leg and tighten them into the pre-secured nuts, greatly simplifying single-person operation. The use of washers further prevents bolt loosening, ensuring reliable seat fixation and enhancing safety.
[0034] Specifically, because the lower ends of the two support legs are tilted away from each other, the seat needs to be adjusted using elongated holes. Since the lower the seat position, the greater the distance between the two seat locking bolts, several slots need to be provided so that the nuts are aligned with the corresponding through holes, facilitating the connection of the seat locking bolts.
[0035] In practice, the support leg has a relief groove 25 facing the pedal locking bolt and the seat locking bolt. The relief groove on the support leg can accommodate the head of the pedal locking bolt and the seat locking bolt, preventing the bolt from protruding from the surface of the support leg and forming a raised structure. This effectively prevents children from being scratched or bumped when they come into contact with the high chair, or from being accidentally caught on their clothes, thus further optimizing the safety performance of the high chair.
[0036] In practice, the two support legs of the support frame are fixedly connected by a reinforcing rod 26. The reinforcing rod fixes the two support legs of the support frame together, enhancing the structural rigidity between the support legs, reducing the risk of deformation of the support legs under stress, improving the overall load-bearing capacity and structural stability of the dining chair, and extending the service life of the product.
[0037] In implementation, the seat frame is integrally manufactured from a support plate, support legs, support arms, and reinforcing rods. The support frame is manufactured using a one-piece molding process, eliminating assembly connection points between the support plate, support legs, support arms, and reinforcing rods. This avoids the risk of structural failure due to loose connections and significantly improves overall strength. Simultaneously, one-piece molding reduces the number of parts and assembly steps, lowering production and assembly costs, and improving production efficiency and product consistency. Specifically, it can be obtained through injection molding.
[0038] In practice, the backrest is designed in an arc shape. The arc-shaped backrest design conforms to the physiological curve of a child's back, better fits the child's back, distributes back pressure, reduces discomfort and fatigue during long periods of sitting, significantly improves the comfort of children's seating, and enhances the user experience of the product.
[0039] Such modifications and variations are permitted without departing from the spirit and scope of this utility model. Thus, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, then this utility model also intends to include these modifications and variations.
