Description

Technical Field

[0001] The invention relates to the technical field of student tables and chairs, in particular to a student table and chair with automatic posture correction function. Background Art

[0002] Posture-correcting student desks and chairs are an innovative type of learning furniture designed specifically for students. They aim to help students develop a correct sitting posture during the learning process, promote healthy physical development, and improve learning efficiency. This type of desk and chair is significantly different from traditional desks and chairs. In terms of design concept, it fully considers the principles of ergonomics. Through reasonable layout and structure, it guides students to naturally maintain a correct sitting posture and reduce problems such as scoliosis and myopia caused by bad sitting posture. At the same time, this type of desk and chair can also cultivate students' good habits and make them pay more attention to the correctness of posture in daily life. For the growth of students, posture-correcting student desks and chairs are of great significance. Students in the growth and development stage have not yet fully matured their bones and muscles. Long-term bad sitting posture may affect the normal development of the body. This type of desk and chair can prevent and correct bad posture to a certain extent, and escort the healthy growth of students.

[0003] Traditional student desks and chairs for posture correction are usually designed on the chair itself, and the posture is corrected through structures such as the chair back. However, it is difficult for traditional student desks and chairs for posture correction to remind students of incorrect postures such as crossing their legs, stretching their legs, and stepping on chair support rods. As a result, incorrect postures will affect the growth of students' spines and develop bad sitting habits.

[0004] Traditional student desks and chairs for correcting posture are divided into two parts: chair and table. However, the chair and table are separated, and it is difficult for students to grasp the distance between the table and chair, which leads to them sitting too close to the table. Some students also rock their chairs or sit at an angle on the chairs. However, traditional student desks and chairs for correcting posture cannot correct these bad habits of students.

[0016] (III) Beneficial effects

[0017] The student desk and chair with automatic posture correction provided by the present invention has the following beneficial effects:

[0018] 1. The present invention uses a prompting component. When a student sits on a chair, he or she steps his or her two feet on the top of two pedals respectively. The pedals drive the pull rod to move downward, and the red warning patch on the top of the warning ball rotates to a green warning patch, indicating that the student's foot posture is correct. When one of the student's feet moves and does not step on the top of the pedal, the green warning patch on the top of the warning ball rotates to a red warning patch again, prompting the student that the foot posture is incorrect, thereby achieving the effect of prompting the student to correct the foot posture. At the same time, when the student's foot does not step on the pedal, it automatically turns into a red warning patch of the warning ball, prompting the student that the foot posture is incorrect. When students sit down to do homework, it is difficult to notice their sitting posture. The warning ball is located on the table and can make the students notice it immediately. Therefore, for incorrect postures of students such as crossing their legs, stretching their legs, and stepping on the chair support rod, the table and chair can automatically prompt the students to correct themselves, thereby avoiding the traditional method of fixing the student's body. The device makes the correct posture easier for students to remember by constantly prompting the students.

[0019] 2. The present invention uses a distance component. When the top of the warning ball is a green warning patch, indicating that the student's feet are sitting correctly, the student's body is too close to the table, and the body will push the push rod, causing the green warning patch on the top of the warning ball to rotate to a red warning patch again, prompting the student that the sitting posture is incorrect. When the top of the warning ball is a red warning patch, indicating that the student's feet are sitting incorrectly, the student's body is too close to the table, and the rotation of the convex strip does not drive the warning ball to rotate. Therefore, the top of the warning ball is still a red warning patch, prompting the student that the sitting posture is incorrect. This achieves the effect of prompting students that their sitting posture is incorrect when their body is too close to the table. When the student's feet are in an incorrect posture and are too close to the table, the warning ball is still a red warning patch to prompt the student that the sitting posture is incorrect.

[0020] 3. The present invention uses a fixed chair assembly. When a student sits on the top of the chair and steps on the pedal, the pedal moves downward, causing the arc block to slide out from the inside of the slide rail. The two arc blocks surround the legs of the fixed chair, thereby achieving the effect of fixing the chair. The chair is fixed when the student sits down and steps on the pedal, avoiding the situation where the student rocks the chair or sits on the chair at an angle, etc. When the student stands up and stops stepping on the pedal, the retraction spring pulls the arc block back into the inside of the slide rail, releasing the legs of the chair to avoid affecting the movement of the chair, so that the chair is fixed during use.

[0043] A convex rail 410 is fixedly connected inside the warning ball 39 . A circular channel is arranged inside the warning ball 39 , and the convex rail 410 is fixedly connected inside the circular channel.

[0044] A retracting assembly for retracting the protruding structure is provided inside the table 1, and the retracting assembly includes a threaded rod 53 that is rotatably connected, a telescopic handle 52 that is slidably connected inside the threaded rod 53, a moving block 51 that is threadedly connected to the outer side of the threaded rod 53, a ball bearing is provided inside the moving block 51, and the ball bearing is slidably connected to the inside of the threaded groove on the outer side of the threaded rod 53, the moving block 51 is fixedly connected to the push rod 41, a connecting rod 54 is rotatably connected to the bottom of the moving block 51, a pressure rod 55 is rotatably connected to the bottom of the connecting rod 54, the pressure rod 55 is slidably connected to the table 1, and the pressure rod 55 is fixedly connected to the pedal 31.

[0045] The fixed chair assembly includes a slider 61 slidably connected to the inside of the pedal 31. The top of the slider 61 is set smaller, and a slope is set on the side of the slider 61. A slide rail 63 is fixedly connected to the outside of the pedal 31. An arc block 62 is slidably connected to the inside of the slide rail 63. There are two arc blocks 62. A retraction spring 64 is fixedly connected to the outside of the slide rail 63, and the retraction spring 64 is fixedly connected to the pedal 31.

[0046] The following is the entire working process and working principle of the above embodiment: the student sits on the top of the chair 2 and steps his two feet on the top of the foot patches of the two pedals 31 respectively. Since the elastic force of the lifting spring 32 is relatively small and can only pull up the pedal 31, the student's foot presses down the pedal 31 with less force, and the pedal 31 drives the lifting spring 32 to extend. The pedal 31 pulls the pull rod 33 to move downward, and the pull rod 33 drives the connecting rod 34 rotatably connected to it to rotate. The connecting rod 34 drives the single inclined block 35 rotatably connected to it to move toward the direction of the circular pendulum 313. At the same time, the pull rod 33 away from the single inclined block 35 drives the double inclined block 36 to move toward the direction of the circular pendulum 313, and the inclined surfaces of the single inclined block 35 and the double inclined block 36 move upward. The circular pendulum 313 is squeezed, and the circular pendulum 313 drives the active rack 312 connected to it to move upward, and the active rack 312 drives the active gear 311 to rotate, and the active rack 312 squeezes the reset spring 310, and the active gear 311 drives the driven gear 37 to rotate, and the driven gear 37 drives the rotating spring 38 to make the warning ball 39 rotate half a circle, so that the red warning patch on the top of the warning ball 39 is rotated to a green warning patch, so that the student's legs are separated and stepped on downward to prevent, indicating that the student's foot posture is correct, when one of the student's feet moves and does not step on the top of the pedal 31, the lifting spring 32 will pull the pedal 31 to move upward to reset, and the pedal 31 pushes the pull rod 33 upward The pull rod 33 drives the connecting rod 34 to make the single inclined block 35 move away from the circular pendulum 313. The circular pendulum 313 loses the support on one side of the single inclined block 35. Therefore, the reset spring 310 stretches and pushes the active rack 312 to move downward. The active rack 312 drives the circular pendulum 313 to move downward. The bottom of the circular pendulum 313 slides downward on the slope of the double inclined block 36, so that the circular pendulum 313 deflects toward the single inclined block 35 at the connection between the circular pendulum 313 and the active rack 312. The active rack 312 moves downward to drive the active gear 311 to rotate. The active gear 311 drives the driven gear 37 to make the warning ball 39 rotate half a circle, so that the green warning patch on the top of the warning ball 39 is again It turns into a red warning sticker, so the students' feet are placed incorrectly, which prompts the students that their foot posture is incorrect, thereby achieving the effect of prompting students to correct their foot posture. At the same time, when the students' feet are not stepping on the pedal 31, it automatically turns into a red warning sticker of the warning ball 39, prompting the students that their foot posture is incorrect. When students sit down to do homework, it is difficult for them to pay attention to their sitting posture. The warning ball 39 is located on the table and can make students notice it immediately. Therefore, for students' incorrect postures such as crossing their legs, stretching their legs, and stepping on the support rod of the chair 2, the table and chair can automatically prompt students to correct themselves, avoiding the traditional method of fixing the students' bodies. Compared with the device, the correction posture is easier for students to remember by constantly prompting students.

[0047] Furthermore, when the top of the warning ball 39 is a green warning patch indicating that the student's feet are sitting in the correct position, the student's body is too close to the table 1, and the body will push the push rod 41 to squeeze the contraction spring 42, and the push rod 41 drives the round rod 44 to move toward the warning ball 39, and the round rod 44 drives the rotating rod 45 connected to it to move toward the warning ball 39, and the rotating rod 45 drives the thin rod 48 and the convex strip 49 to penetrate into the warning ball 39. Since the top of the warning ball 39 is a green warning patch, the warning ball 39 rotates half a circle, so the warning ball 39 drives The return spring 310 moves to the top of the warning ball 39, so the convex strip 49 penetrates into the warning ball 39 and slides into the convex rail 410. At the same time, the rotating rod 45 drives the convex block 47 fixedly connected thereto to move into the thread groove of the screw block 46. The thread groove squeezes the convex block 47 so that the convex block 47 rotates along the thread groove. The convex block 47 drives the rotating rod 45 to rotate half a circle. The rotating rod 45 drives the thin rod 48 to rotate the convex strip 49 half a circle. Therefore, the convex strip 49 drives the convex rail 410 to rotate the warning ball 39 half a circle, so that the warning ball 39 tops The green warning patch on the top of the warning ball 39 turns to a red warning patch again, reminding the student that the sitting posture is incorrect. When the top of the warning ball 39 is a red warning patch, it means that the student's feet are sitting in an incorrect position. The student's body is too close to the table 1, and the body will push the push rod 41 to squeeze the contraction spring 42. The push rod 41 drives the round rod 44 to move toward the warning ball 39. The round rod 44 drives the rotating rod 45 to move toward the warning ball 39. The rotating rod 45 drives the thin rod 48 and the convex strip 49 to penetrate into the warning ball 39. Since the top of the warning ball 39 is a red warning patch, it is The warning ball 39 does not rotate, so the reset spring 310 is located at the bottom of the warning ball 39, so the convex strip 49 does not slide into the convex rail 410, so the rotation of the convex strip 49 does not drive the convex rail 410 to rotate the warning ball 39, so the top of the warning ball 39 is still a red warning patch, reminding students that their sitting posture is incorrect, achieving the effect of reminding students that their sitting posture is incorrect when their body is too close to the table 1. When the student's feet are in the wrong posture and too close to the table 1, the warning ball 39 is still a red warning patch to remind students that their sitting posture is incorrect.

[0048] Furthermore, the user can pull out the telescopic handle 52 and rotate the telescopic handle 52, the telescopic handle 52 drives the threaded rod 53 to rotate, the threaded rod 53 drives the moving block 51 threadedly connected to it to move away from the telescopic handle 52, the moving block 51 drives the push rod 41 fixedly connected to it to be retracted into the table 1, and at the same time the moving block 51 drives the connecting rod 54 rotatably connected to it to move downward, the connecting rod 54 pushes the pressure rod 55 to move downward, and the pressure rod 55 pushes the pedal 31 fixedly connected to it to move downward, thereby achieving the effect of retracting the push rod 41 and lowering the pedal 31, thereby converting the correction table and chair into a normal table and chair.

[0049] Furthermore, before the student sits on the top of the chair 2, the student places the legs of the chair 2 inside the two slide rails 63. When the student sits on the top of the chair 2 and steps on the pedal 31, the pedal 31 moves downward, so that the inclined surface of the slider 61 squeezes the arc block 62, so that the arc block 62 slides out from the inside of the slide rail 63, and the arc block 62 pulls the retraction spring 64 fixedly connected to it to stretch. The two arc blocks 62 surround the legs of the fixed chair 2, thereby achieving the effect of fixing the chair 2, so that the student can fix the chair 2 when sitting down and stepping on the pedal 31, avoiding the situation where the student shakes the chair 2, sits on the chair 2 at an angle, etc., and when the student stands up and does not step on the pedal 31, the retraction spring 64 pulls the arc block 62 back into the inside of the slide rail 63, releasing the legs of the chair 2, avoiding affecting the movement of the chair 2, so that the chair 2 is not fixed when not in use.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
