Description

Technical Field

[0001] The invention relates to the field of teaching equipment, in particular to a student chair used for classroom learning. Background Art

[0002] Teaching desks and chairs are divided into movable and fixed types. The chairs of the former are generally movable, so that students can adjust their positions according to their comfort; the chairs of the latter are generally fixed to the ground to prevent the chairs from being moved or lost, which is not easy to manage. However, the desks and chairs for primary school students are generally movable. Because the body shapes of primary school students are different, the chairs and tables need to be adjusted to the most suitable place to maintain the most comfortable and correct posture for better learning. However, there is a problem with movable desks and chairs. Students will move their chairs as close to the table as possible when doing homework or reading.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] like Figures 1 to 5 As shown, the present invention provides a student chair for classroom learning, including a chair body, the chair body including a chair support frame 2 and a chair panel 1, the chair support frame 2 and the chair panel 1 are slidably connected, the upper end of the chair support frame 2 is provided with a first rack group 4, the chair panel 1 is provided with a second rack group 5 that meshes with the first rack group 4 when the first rack group 4 is pressed downward, the chair panel 1 is provided with a bumper 7 located beside the second rack group 5, the bumper 7 abuts against the upper end of the chair support frame 2; the bottom end of the chair support frame 2 is provided with a foot cover 6, the foot cover 6 includes a half-open box body 12, a roller 8 and a support plate 9, the bottom of the half-open box body 12 is provided with a groove, the support plate 9 is elastically connected to the top of the groove in the half-open box body 12, and the support plate 9 is connected to the roller 8 through a bearing.

[0030] The lower end of the chair support frame 2 is supported on the ground. When the student sits on the chair panel 1, the second rack set 5 on the chair panel 1 is squeezed and meshed with the first rack set 4 on the upper end of the chair support frame 2, so that the chair panel 1 will not slide relative to the chair support frame 2 when the student sits on the chair. At the same time, the entire chair body receives pressure to squeeze the foot cover 6, so that the roller 8 on the foot cover 6 compresses the spring 10 and enters the groove of the half-open box body 12 and cannot roll. In this way, the entire chair body cannot be easily moved to form a fixed position, which is convenient for students to sit. When the student leaves the chair panel 1, the pressure is eliminated, the roller 8 pops out, and the bumper 7 also pops out. At this time, due to the weight of the chair, although the roller 8 contacts the ground, it will not roll by itself unless the backrest 3 is pulled. However, the chair panel 1 is relatively light, and the chair panel 1 is slidably connected to the chair support frame 2. At this time, a slight push of the chair panel 1 can slide backwards and overlap and close with the chair support frame 2, which is convenient for students to stand or leave their seats.

[0031] As and Figure 2 As shown, an embodiment of the present invention also provides a toothed groove structure of a student chair for classroom learning, including a chair body, wherein the chair body includes a chair support frame 2 and a chair panel 1, wherein the chair support frame 2 is slidably connected to the chair panel 1, and a first rack group 4 is provided at the upper end of the chair support frame 2, and a second rack group 5 is provided on the chair panel 1 for meshing with the first rack group 4 when the first rack group 4 is pressed downward, and a bump bead 7 is provided on the chair panel 1 and is located next to the second rack group 5, and the bump bead 7 abuts against the upper end of the chair support frame 2.

[0032] When the first rack set 4 and the second rack set 5 are squeezed, they are meshed and cannot slide. When there is no squeezing, the two rack sets are pushed apart by the rebound force of the bump ball 7, and the ball can roll, so that the chair panel 1 and the chair support frame 2 can slide.

[0033] When a student sits on the chair panel 1, the chair panel 1 presses the elastic body downwards and causes the rack to mesh and get stuck, so that the chair panel 1 cannot slide forward and backward to achieve the purpose of being fixed; when a student needs to stand up to speak or leave his seat, the elastic body automatically pops the chair panel 1 upwards, and the rack separates, so that the chair panel 1 can slide backwards to facilitate the student to stand; when the chair needs to be moved, it can be rolled away by the roller 8. The structure is simple and easy to use, which greatly improves the learning experience of students.

[0034] In a preferred embodiment, the first rack assembly 4 includes a left slide groove and a right slide groove that are symmetrical to each other, and the second rack assembly 5 includes a left slider and a right slider that are slidably connected to the left slide groove and the right slide groove, respectively. The slide groove is separated from the rack, and when the two rack assemblies are separated, the slider can slide along the slide groove, and when the two racks are engaged, the slider cannot slide.

[0035] In a preferred solution, the left and right slide grooves are two inverted L-shaped grooves symmetrically distributed along the center line, and the left and right sliders are two L-shaped blocks respectively connected to the two inverted L-shaped grooves in an inverted sliding manner. The L-shape can slide effectively and prevent the slider from being separated from the slide groove left and right and up and down, thereby limiting the freedom of lateral movement and the freedom of the vertical direction.

[0036] In a preferred solution, the vertical bumpers 7 are symmetrically distributed on both sides of the chair panel 1, and the number of bumpers on a single side is at least two. Multiple bumpers 7 can disperse the load, and the load is more balanced and stable, which can better push the support panel open.

[0039] like Figure 4 and Figure 5 As shown, the embodiment of the present invention also provides a foot cover 6 of a student chair for classroom learning, comprising a half-open box body 12, a roller 8 and a support plate 9 installed at the bottom end of the chair support frame 2. The bottom of the half-open box body 12 is provided with a groove, and the support plate 9 is elastically connected to the top of the groove in the half-open box body 12, and the support plate 9 is connected to the roller 8 through a bearing. When someone sits on the chair panel 1, the entire chair body receives pressure to squeeze the foot cover 6, so that the roller 8 on the foot cover 6 compresses the spring 10 and enters the groove of the half-open box body 12 and cannot roll. At this time, the chair support frame 2 is close to the ground. In this way, the entire chair body cannot be easily moved and is fixed. After the students sit down, the chair cannot be easily moved, which avoids noise and prevents students from changing seats in class. When the student leaves the chair panel 1, the pressure is eliminated, the roller 8 pops out, and the student can push the entire chair to roll.

[0040] Preferably, the diameter of the roller 8 is smaller than the depth of the groove, so that the entire roller 8 can be completely retracted into the groove during squeezing.

[0041] In a preferred solution, a guide rod 11 is provided at the top of the groove, a limit plate is provided at the lower end of the guide rod 11, and the support plate 9 is slidably mounted on the guide rod 11.

[0042] Preferably, the guide rod 11 is sleeved with a spring 10, one end of the spring 10 rests against the top of the groove, and the other end is fixedly connected to the support plate 9. The spring 10 is sleeved on the guide rod 11 and will not fall off.

[0043] Preferably, the guide rod 11 includes a front guide rod 11 and a rear guide rod 11, and the front guide rod 11 and the rear guide rod 11 are respectively located at the front end and the rear end of the roller 8. A plurality of guide rods 11 make the entire structure more stable.

[0044] In a preferred embodiment, the support plate 9 is an annular plate with upper and lower openings, a latch 13 is provided between the left and right sides of the annular plate, and the roller 8 is connected to the latch 13 through a bearing. The roller 8 is located in the annular plate and is connected in a rolling manner through the latch 13. The roller 8 rotates around the latch 13 to drive the chair to move.

[0045] like Figure 1 As described above, the embodiment of the present invention also provides a light slide structure of a student chair for classroom learning, comprising a chair body, the chair body comprising a chair support frame 2 and a chair panel 1, the chair support frame 2 and the chair panel 1 are slidably connected, the upper end of the chair support frame 2 is provided with a left slide and a right slide symmetrical along the center line of the chair panel 1, and the lower end of the chair panel 1 is provided with a left slider and a right slider respectively connected to the left slide and the right slide. The left slide and the right slide are inverted L-shaped grooves, and the left slider and the right slider are L-shaped blocks. When the student sits on the chair panel 1, the sliding groove and the slider have a large extrusion friction force, so the chair panel 1 cannot slide forward and backward to achieve the purpose of fixing; when the student needs to stand up to speak or leave the seat, the sliding groove and the slider have basically no extrusion force, so that the chair panel 1 can be slid backward to facilitate the student to stand. The structure is simple and light, easy to use, and greatly improves the learning experience of students. And the inverted L-shaped groove and the L-shaped block are hooked upside down to limit the horizontal movement freedom and vertical movement freedom of the chair panel 1 and the chair support frame 2.

[0046] In a preferred solution, the left slide groove, the right slide groove, the left slider and the right slider are all made of plastic, which is light and strong enough to bear the weight of the student.

[0047] Preferably, an anti-skid cover is provided at the bottom end of the chair support frame 2. The anti-skid cover is used to prevent sliding and can be made of rubber material.

[0048] In a preferred solution, a ball bearing is provided in the left slide groove and is connected to the left slider in a rolling manner, and a ball bearing is provided in the right slide groove and is connected to the right slider in a rolling manner.
