Description

Technical Field

[0001] This utility model relates to study desks and chairs, and more particularly to an integrated adjustable study desk and chair. Background Technology

[0002] Nowadays, people are paying more and more attention to children's learning. Unlike the office desks and chairs we see every day, children's study desks and chairs are specially designed for children's learning and play an auxiliary role in the process of children's growth. Traditional study desks and chairs are mostly separate, taking up too much space and making it inconvenient to adjust their position. Because children are naturally active, their positions are also very easy to move, requiring parents to constantly supervise and adjust their positions, which is not conducive to the development of children's correct sitting posture.

[0003] Therefore, integrated study desks and chairs have gradually appeared on the market, including a base and a chair and table mounted on the base, with casters installed under the base. These desks and chairs allow for height adjustment of the table and chair, but the fixed spacing between them means that for some slender users, the distance is too large, making it difficult to reach the desktop. Conversely, for more robust users, the distance may be too small, making it inconvenient to get in and out. This design fails to meet the needs of all users and is therefore impractical. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an integrated adjustable study desk and chair. In addition to being height adjustable, the distance between the desk and the chair can also be adjusted according to the user's needs, making it highly practical.

[0005] The technical solution of this utility model is as follows: An integrated adjustable study desk and chair, including a base and a chair body and a table body installed on the base. The table body includes a tabletop, a support frame, and table legs. The support frame is installed on the upper end of the table legs, and the lower end of the table legs is installed on the base. The chair body includes a seat and chair legs. The lower end of the chair legs is installed on the base, and the seat is installed on the upper end of the chair legs. The lower end surface of the tabletop is provided with a slide rail. The slide rail is parallel to the base. The support frame is partially located within the slide rail and slides in cooperation with the slide rail to adjust the distance between the tabletop and the chair body. It also includes a locking component. The locking component has a locked state and an unlocked state. In the locked state, the tabletop and the support frame are relatively fixed. In the unlocked state, the tabletop and the support frame can slide relative to each other.

[0006] The above technical solution allows for adjustment of the distance between the table and seat, making it suitable for people of different heights. Users can adjust the distance according to their needs. After adjustment, the table and chair are relatively fixed to prevent movement when children are using the chair, thus avoiding disruption. When adjustment is needed, the table can be unlocked and slid relative to the support frame, either closer to the seat or further away from it. After adjustment, the table is locked to prevent it from sliding automatically during use.

[0007] A further feature of this invention is that the locking assembly includes a locking hook hinged to the tabletop and several locking slots provided on the support frame. Each locking slot is arranged sequentially along the sliding direction of the support frame. When the locking hook is engaged in a locking slot, the locking assembly is in a locked state.

[0008] With the above-mentioned further design, the structure is simple and easy to operate. The tabletop is equipped with a mounting base, and the locking hook includes a pressing end and a locking end. The middle part of the locking hook is hinged to the mounting base, and the mounting base is equipped with a torsion spring. One end of the torsion spring presses against the mounting base, and the other end presses against the locking hook. The locking end of the locking hook cooperates with the locking groove. Pressing the pressing end of the locking hook causes the locking end of the locking hook to disengage from the locking groove. At this time, it is in the unlocked state, and the tabletop can be slid. Releasing the locking hook causes the locking end of the locking hook to engage with the locking groove under the action of the torsion spring. At this time, it is in the locked state, and the tabletop is locked and cannot be slid.

[0009] A further feature of this invention is that the support frame is provided with a connecting block, the connecting block is located inside the slide rail and slides and engages with the slide rail, and the connecting block is provided with a plurality of rollers along its sliding direction, each roller contacting the side wall of the slide rail.

[0011] With the above-mentioned further design, the rollers and balls make the connecting block slide more smoothly in the slide rail, reducing the friction between the connecting block and the slide rail. Only a small force is needed to achieve sliding, and children can operate it by themselves. The convex strips increase the contact area with the slide rail and improve stability.

[0012] A further feature of this invention is that the lower end face of the tabletop is provided with a frame, which includes two opposing first mounting rods and a second mounting rod vertically disposed between the two first mounting rods. The two first mounting rods are arranged parallel to the slide rails. There are two slide rails, which are disposed opposite to each other on the inner side of the two first mounting rods and connected to the first mounting rods. The support frame is located between the two slide rails and slides in cooperation with the two slide rails.

[0013] With the above-mentioned further configuration, two slide rails are set, and the two sides of the support frame slide and cooperate with the corresponding slide rails respectively, so that the structure is more stable and does not deviate when the table slides. The slide rails are fixedly connected to the first mounting rod by screws, and the mounting base is set on the first mounting rod. The locking hook is hinged to one end of the mounting base and extends outward from the table for easy operation and unlocking.

[0014] A further feature of this invention is that the base is provided with a foot pedal, which is slidably disposed between the chair leg and the table leg.

[0015] With the above-mentioned further design, the foot pedal can be stepped on, improving comfort and preventing users from crossing their legs. The foot pedal is movable, making it highly practical and suitable for users of different heights.

[0016] A further feature of this invention is that the end of the tabletop away from the chair body is provided with a guardrail, which is detachably connected to the tabletop via a connecting seat.

[0017] With the above-mentioned further configuration, it can be assembled as needed. The connecting base is connected to the tabletop with screws, which is convenient and quick to disassemble. After the enclosure is installed, it can block items on the tabletop and prevent them from falling.

[0018] A further feature of this invention is that a sleeve post is inserted into the fence, the lower end of the sleeve post is connected to a second mounting rod, a support rod is provided inside the sleeve post, and a reading light is provided at the upper end of the support rod.

[0019] With the above-mentioned further design, multiple functions can be achieved by installing the reading light on the enclosure to prevent other items from occupying the desktop.

[0020] A further feature of this invention is that the chair body also includes a backrest, the lower end of the backrest is provided with a sliding rod, the lower end surface of the seat is provided with a fixing rod, and the sliding rod is located inside the fixing rod and can slide relative to the fixing rod.

[0021] With the above-mentioned further settings, the backrest position can be adjusted according to different users, so that users can lean against the backrest to support their back and avoid hunching.
