Description

Technical Field

[0001] This application relates to the field of nap chairs, and in particular to nap chairs for students. Background Technology

[0002] Currently available nap chairs all have both headrest and backrest functions to improve students' comfort during long periods of sitting. However, this increases the cost of manufacturing nap chairs. Moreover, when students recline the chair back for napping, the backrest cannot be removed, resulting in a raised lower back when students lie down. This is especially true for those who like to lie on their side during naps, as the presence of the backrest makes it less comfortable for them. Utility Model Content

[0003] To address the practical need for backrest pillows, this application provides a student nap chair.

[0004] The student nap chair provided in this application adopts the following technical solution:

[0005] include:

[0006] Seat plate;

[0007] The chair back is rotatably mounted on the seat.

[0008] The table legs are symmetrically located at the bottom of the seat.

[0009] pillow;

[0010] The chair back is equipped with a support frame, and a connecting rod is rotatably mounted on the support frame. One end of the connecting rod is rotatably connected to the backrest. The chair back has a slot at the position corresponding to the waist of the human body for the backrest to pass through. When the connecting rod rotates, the backrest has two states: in the first state, the backrest corresponds to the human head; in the second state, the backrest corresponds to the human waist, and the backrest passes through the slot in an arched shape.

[0011] The pillow can be rotated through the connection of the connecting rod and the support frame, allowing it to be changed from a headrest to a lumbar support, or vice versa, according to the student's needs. This increases the pillow's usability and reduces costs during the manufacturing of the nap chair.

[0012] In one possible implementation, the support frame has a first through hole, and the connecting rod has a second through hole corresponding to the first through hole. The first through hole and the second through hole are connected sequentially by a first pin.

[0013] In one possible implementation, the support frame is provided with two third through holes, and the connecting rod is provided with a fourth through hole that mates with the third through holes. The third through holes and the fourth through holes are connected in sequence by a second pin.

[0014] In one possible implementation, the second pin includes a bolt and a nut.

[0015] In one possible implementation, the first through hole is located between the two third through holes.

[0016] In one possible implementation, the base plate is provided with a connecting frame, and the connecting frame and the support frame are rotatably connected by a third pin.

[0017] In one possible implementation, the table legs are connected to the seat via a lifting rod, and friction pads are provided at the lower ends of the table legs.

[0018] In one possible implementation, the student nap chair also includes:

[0019] The footrest is mounted on the bottom of the seat via a sliding rod;

[0020] The footrest has grooves to facilitate the placement of the feet.

[0021] In one possible implementation, the student nap chair also includes a storage box for easy placement of items.

[0022] In one possible implementation, the storage box has an opening at one end and is located at the lower end of the base plate. Sliders are provided at both ends of the storage box, and grooves that cooperate with the sliders are provided on the two table legs.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] The pillow can be rotated through the connection of the connecting rod and the support frame, allowing it to be changed from a headrest to a lumbar support, or vice versa, according to the student's needs. This increases the pillow's usability and reduces costs during the manufacturing of the nap chair. Attached Figure Description

[0035] Reference Figure 1-5A student nap chair includes a seat 1, a backrest 2, table legs 3, a backrest 4, a height adjustment rod 5, a footrest 6, a sliding rod 7, and a storage box 8. The backrest 2 is rotatably mounted on the seat 1. A ratchet mechanism is provided between the backrest 2 and the seat 1, which facilitates the adjustment of the backrest 2's angle and its subsequent fixation. The ratchet mechanism is existing technology and will not be described in detail. The table legs 3 are symmetrically located at the lower end of the seat 1 and are connected to the seat 1 via the height adjustment rod 5. The lower end of the table legs 3 is equipped with a friction pad 9. The footrest 6 is located at the bottom of the seat 1 via the sliding rod 7 and has a groove 10 for comfortable foot placement. The storage box 8 is located at the lower end of the seat 1 and is slidably connected to the table legs 3. One end of the storage box 8 has an opening, allowing it to be moved to the outside of the seat 1 for easy access and placement of items.
