Description

Technical Field

[0001] This utility model relates to the field of lunch break chair technology, and in particular to a lunch break chair for classrooms. Background Technology

[0002] Chairs are common household items. Previously, chairs were simply a home furnishing, but later, based on different usage environments and users, they were categorized as office chairs, home chairs, and school chairs. This application for a nap chair is primarily for school students. Scientific research shows that sufficient and good sleep every day is a key factor in the height of primary and secondary school students. Insufficient sleep or poor sleep quality can affect a child's height development. Most primary and secondary school students are day students, going to school in the morning and returning home in the afternoon, meaning they lack beds for lunch breaks. Many students rest on their desks during lunch breaks, a posture that is tiring and uncomfortable, unsuitable for sleeping. Arranging beds in the classroom is very troublesome. First, storage is inconvenient. Unlike kindergartens, primary and secondary school children are much smaller, and the space they occupy is limited. While beds can be made in the classroom, primary and secondary school students are taller, and sleeping takes up space. Furthermore, a primary or secondary school class has more students than a kindergarten class, making it impossible for everyone to make beds and rest in the classroom. Therefore, modifying the already essential chair into a reclining nap chair is a better solution.

[0003] Publication (Announcement) No.: CN220141190U A nap chair includes a seat cushion, an adjustable backrest, an adjustable foot pad located under the seat cushion, and chair legs located under the seat cushion. A backrest support is provided at the rear of the backrest, which includes an upper support and an explosion-proof shell. This nap chair has the advantages of adjustable backrest angle and high safety.

[0004] The existing lunch break chairs are not convenient for students to lie down and rest, and the backrest angle is not easy to adjust, so they cannot meet the needs of students for rest. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing lunch break chairs, such as inconvenience in lying down for rest and inconvenience in adjusting the backrest angle, which cannot meet the needs of students for rest. Therefore, a classroom lunch break chair is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A classroom nap chair includes:

[0008] The base has a support leg fixedly installed on its top, a seat is provided on the top of the support leg, armrests are provided on both sides of the seat, and a storage basket is provided on the front side of the support leg.

[0009] The leg support mechanism is located at the bottom of the seat;

[0010] The backrest mechanism is located at the rear of the seat.

[0011] Preferably, the leg support mechanism includes a fixed plate, which is installed at the bottom of the seat. A telescopic groove is provided on the front side of the fixed plate, and an adjusting plate is slidably installed in the telescopic groove. A support plate is fixedly installed on the front side of the adjusting plate. When the support plate is pulled, the support plate causes the adjusting plate to slide in the telescopic groove, thereby supporting the student's legs.

[0012] Preferably, the bottom of the adjusting plate has two limiting grooves, and the bottom inner wall of the telescopic groove has two limiting blocks fixedly installed, with the two limiting blocks cooperating with the two limiting grooves; this can prevent the adjusting plate from detaching from the telescopic groove.

[0013] Preferably, the backrest mechanism includes a backrest panel, a first vertical plate and a second vertical plate are fixedly installed at the bottom of the backrest panel, the first vertical plate and the second vertical plate are rotatably installed on both sides of the seat, a rotating column is rotatably installed on the outer side of the first vertical plate and the second vertical plate, both of the rotating columns are fixedly installed with the seat, and a book storage bag is provided on the rear side of the backrest panel.

[0014] Preferably, a hexagonal slot is formed on the rotating column of the first vertical plate, and a hexagonal column is slidably installed in the hexagonal slot. A handle is fixedly installed on the outer side of the hexagonal column, and multiple positioning rods are fixedly installed on the inner side of the handle. Multiple positioning slots are formed on the outer side of the first vertical plate, and the positioning rods cooperate with the positioning slots. A tension spring is fixedly installed on the inner end of the hexagonal column, and the other end of the tension spring is fixedly installed to the inner wall of the hexagonal slot. The tension spring provides tension to the hexagonal column, so that the handle drives the positioning rods to insert into the positioning slots, thereby fixing the handle.

[0015] The beneficial effects of the classroom nap chair described in this utility model are as follows:

[0016] When students need to take a nap, the support plate is pulled, which causes the adjustment plate to slide within the telescopic groove. The support plate provides support for the students' legs. When the angle of the backrest needs to be adjusted, the handle is pulled outward to move multiple positioning rods away from multiple positioning grooves, which releases the handle from its fixation. The handle, through the cooperation of the hexagonal post and the hexagonal groove, allows the first vertical plate to adjust the angle of the backrest, allowing the students to lie down and rest.

[0017] This utility model has a simple structure and can be modified to support the legs with a support plate. The backrest can be tilted and reclined to allow students to lie down and rest, thus improving their comfort. Attached Figure Description
