Description

Technical Field

[0001] The invention relates to the technical field of student chairs, in particular to a chair for correcting study posture. Background Art

[0002] A good study posture is a basic requirement to protect eyesight and prevent hunchback, so a large number of chairs that can correct sitting posture are needed.

[0003] Although everyone strictly requires themselves to correct their study posture, which is beneficial to personal image, physical development, and prevention of myopia, in the actual learning process, they will slowly lower their heads, bend over, and hunch their backs, which are difficult to maintain for a long time. In fact, it is very difficult to control the sitting posture by ourselves. At this time, we need to use external equipment to assist us in adjusting the sitting posture. However, the common seats on the market, although they have certain functions of adjusting the sitting posture, are limited to the surface and are not effective in actual use. The main reason is that most seats can only support the back but not the chest. As a result, no matter how the back is supported, the user will still lean forward, making it difficult to achieve the purpose of adjusting the sitting posture.

[0038] Two mounting frames 2116 are provided below the seat plate 11. The upper surface of each mounting frame 2116 contacts the bottom surface of the seat plate 11 and the support curved beam 2101. Four bolts 2117 are provided below each mounting frame 2116. The top of each bolt 2117 penetrates the mounting frame 2116 and is threadedly connected to the inner wall of the seat plate 11. The support curved beam 2101 can be stably fixed by the cooperation of the mounting frames 2116 and the bolts 2117. The two mounting frames 2116 are used for fixing, thereby further improving the stability of the support curved beam 2101.

[0039] A back pad 2118 is fixedly connected to the inner wall of the backrest board 2104, and the outer surface of the backrest curved plate 2112 contacts the inner wall of the back pad 2118. Two side pads 2119 are fixedly connected to the inner wall of the backrest board 2104. A lumbar pad 2120 is fixedly connected to the inner wall of the backrest board 2104, and the inner wall of the lumbar pad 2120 contacts the outer surface of the back support board 2107.

The lumbar pad 2120 is wrapped around the outer surface of the back support board 2107 to improve the comfort of the waist.

[0040] The specific implementation of this embodiment is as follows: first, two mounting frames 2116 are provided to clamp the support curved beam 2101 to the bottom surface of the seat plate 11, and each mounting frame 2116 is fixed by four bolts 2117. Then, when the user reclines the chair, the rigidity of the material of the support curved beam 2101 itself can be used to hold the user's back and buffer part of the impact force. At this time, the back pad 2118, side pad 2119 and waist pad 2120 are used to hold the user's back together, and the sponge filled inside them can absorb part of the backward force. When in use, the height of the backrest board 2104 is adjusted according to the height of the user. First, the first threaded knob 2105 is reversed to loosen the first threaded knob 2105. The backrest board 2104 is moved up and down by rotating the first threaded knob 2105 clockwise, and the first threaded knob 2105 passes through the silicone pad 2106 and the support curved beam 2101 and is threadedly connected to the inner wall of the sliding block 2102. The first threaded knob 2105 is continuously rotated clockwise to rotate the first threaded knob 2105 ... The button 2105 can now squeeze the silicone pad 2106, and then use the silicone pad 2106 to squeeze the supporting curved beam 2101 to fix the sliding block 2102 and the backrest board 2104 as a whole. After adjusting the height, the backrest curved plate 2112 is fixedly connected to the backrest board 2104. When leaning on it, a thrust force of the back presses the backrest curved plate 2112 backward, and the backrest curved plate 2112 uses the first spring 2113 to generate a rebound force after being squeezed. Therefore, these two forces will form a direction of impact to support the upper part of the user's back. Similarly, when the back leans backward, the lower part of the back of the human body structure is closer to the waist than the upper part, which is farther back. Therefore, the curvature of the chasing back support plate 2107 is also relatively large. At this time, one end of the chasing back support plate 2107 is fixedly connected to the backrest plate 2104, and the other end is fixedly connected to the sliding ring 2108. First, the staff manually holds the lifting rod 2109 to drive the sliding ring 2108 to slide along the supporting curved beam 2101. After adjusting to the appropriate position of the user according to the opened limiting hole 2111, the limiting rod 2110 is inserted into the sliding ring 2108 and the limiting hole 2111 to achieve the purpose of fixing the sliding ring 2108. After adjusting the height of the chasing back support plate 2107, when the user leans back, a counteracting force will be formed with the rebound force of the curvature of the chasing back support plate 2107, thereby achieving the purpose of flexible support.

[0041] Example 2: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a chair for correcting learning posture. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The correction mechanism 2 also includes a limit unit 22, which is located inside the seat plate 11. The limit unit 22 can prevent the user from leaning forward and has the function of maintaining eye distance.

[0042] As a further limitation of the correction mechanism 2 of the present invention, the limiting unit 22 includes two slideways 2201, the outer surface of each slideway 2201 is fixedly connected to the inner wall of the seat plate 11, the inner walls of the two slideways 2201 are slidably connected to a slide bar 2202, the left and right sides of the bottom of the slide bar 2202 are fixedly connected to a threaded tube 2203, the outer surface of each threaded tube 2203 is in contact with the inner wall of the slideway 2201, the top of the slide bar 2202 is slidably connected to an adjustment rod 2204, one end of the adjustment rod 2204 passes through the top of the slide bar 2202 and is fixedly connected to a rotating seat 2206, the slide bar 2202 is threadedly connected to a second threaded knob 2205, and the second threaded knob 22 After one end of 05 extends into the interior of the slide bar 2202, the adjustment rod 2204 is limited. A third threaded knob 2207 is provided on the outer side of each slideway 2201. The ends of the two third threaded knobs 2207 that are close to each other penetrate the slideway 2201 and are threadedly connected to the inner wall of the threaded tube 2203. By providing a limiting unit 22, the chest of the user can be supported. The slide bar 2202 slides inside the two slideways 2201 using two threaded tubes 2203, so that the slide bar 2202 has two different forms and can switch between the writing sitting posture and the reading sitting posture. The limiting unit 22 can limit the user's body in multiple sitting posture modes.

[0043] The left and right sides of the seat plate 11 are fixedly connected with side rods 2208, and the outer surface of each side rod 2208 is rotatably connected with a handrail 2209. The two side rods 2208 are used to support the handrail 2209 respectively.

The upper surface of the seat plate 11 is fixedly connected with a seat cushion 2211. The armrest pads 2210 are used to relieve the contact pressure between the user's arms and the armrests, thereby improving the user's comfort in using the chair and ensuring a comfortable touch. The seat cushion 2211 itself is made of memory foam and has a high degree of comfort. It is not easy to feel buttock pain when sitting on it for a long time.

[0045] The specific implementation method of this embodiment is as follows: first, the slide bar 2202 uses the two threaded tubes 2203 to slide inside the two slideways 2201, so that the slide bar 2202 can slide into two different forms, that is, it can switch between the two sitting postures of writing and reading. The specific operation is firstly to rotate the two third threaded knobs 2207 counterclockwise to rotate the two third threaded knobs 2207 back into the inside of the slideway 2201. At this time, the two third threaded knobs 2207 no longer limit the slide bar 2202, and the slide bar 2202 can be freely moved inside the two slideways 2201. Then, the slide bar 2202 is manually dragged out. When the slide bar 2202 is dragged to the front, the slide bar 2202 is rotated ninety degrees to stand up the slide bar 2202. Then, the two third threaded knobs 2207 are rotated clockwise again. At this time, the two third threaded knobs 2207 are respectively threadedly connected with the threaded tubes 2203. By rotating the two third threaded knobs 2207 clockwise, the The third threaded knob 2207 squeezes the slideway 2201 in opposite directions to each other, thereby achieving the purpose of fixing the slide bar 2202. When the slide bar 2202 is upright and fixed, the adjustment rod 2204 is used to slide inside the slide bar 2202. At this time, the tightness of the adjustment rod 2204 can be controlled by adjusting the second threaded knob 2205. The forward and backward movement of the adjustment rod 2204 is convenient for adapting to users of different body shapes. At this time, the rotating seat 2206 fixedly connected to the adjustment rod 2204 is used to provide the device with chest pads of different styles. When it is necessary to switch the reading mode, it is only necessary to rotate the two third threaded knobs 2207 counterclockwise again to loosen the slide bar 2202, manually rotate the slide bar 2202 ninety degrees and insert it into the two slideways 2201, and then rotate the two third threaded knobs 2207 clockwise again to simply fix the outer surface of the slide bar 2202. At this time, the rotating seat 2206 faces upward, and the chest pad can be used as a knee joint support pad.

[0046] Example 3: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a chair for correcting learning posture. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A fatigue relief mechanism 3 is arranged above the seat plate 11. The fatigue relief mechanism 3 is arranged on an end of the limiting unit 22 away from the seat plate 11. The fatigue relief mechanism 3 is used in conjunction with the limiting unit 22. The fatigue relief mechanism 3 is used to improve the comfort of users and relieve fatigue and discomfort.

[0047] As a further limitation of the fatigue relieving mechanism 3 of the present invention, the fatigue relieving mechanism 3 includes a chest support plate 301, the front of the chest support plate 301 is fixedly connected with a hinge seat 302, the outer surface of the hinge seat 302 is rotatably connected to the outer surface of the rotating seat 2206, and is installed by a latch assembly, the back of the chest support plate 301 is fixedly connected with two side leakage plates 303, the back of the chest support plate 301 is fixedly connected with three second springs 305, and a filling sponge 304 is arranged on the outer side of the chest support plate 301, the outer surfaces of the three second springs 305 are in contact with the inner wall of the filling sponge 304, and the outer surface of the filling sponge 304 is fixedly connected A plurality of convex sponges 306 are connected, and the outer surface of the filling sponge 304 is covered with a tensile cotton cloth 307, and the outer surface of the tensile cotton cloth 307 is covered with a breathable cloth cover 308, and the edges of the breathable cloth cover 308 are fixedly connected to the edges of the chest support plate 301. By providing a fatigue relief mechanism 3, the chest fatigue of the user can be relieved. In a long-term writing posture, the chest may feel uncomfortable due to the limit unit 22. At this time, the filling sponge 304, the second spring 305 and the convex sponge 306 cooperate to achieve the effect of relieving chest discomfort, thereby improving the comfort of the user in using the device;

[0048] Two aromatherapy blocks 309 are arranged inside the filling sponge 304, and the front side of the chest support plate 301 is rotatably connected to two rotating plates 310. The two openable rotating plates 310 are used to facilitate the replacement of the aromatherapy blocks 309. The aromatherapy blocks 309 can replace corresponding fragrances according to the user's preferences, thereby further alleviating the user's psychological fatigue.

[0049] The specific implementation of this embodiment is as follows: first, the chest support plate 301 is used to fix the hinge seat 302, and then the hinge seat 302 is used to rotate and connect with the rotating seat 2206, and the latch assembly is used to limit the installation, so that the fatigue relief mechanism 3 has the advantage of being detachable and convenient for daily cleaning and replacement. At this time, when the user's chest is close to the breathable cloth cover 308, the filling sponge 304 and three second springs 305 arranged inside it can effectively achieve the purpose of soft cushioning, so that the user will not feel uncomfortable when using it for a long time. In addition, the relationship between the connection between several convex sponges 306 and the tensile cotton cloth 307 is used to ensure that the filling sponge 304 and the three second springs 305 are connected. There are several convex sponges 306 between the sponge 304 and the tensile cotton cloth 307, so as to achieve the purpose of supporting the gap and make the breast pad have good air permeability. The use of the tensile cotton cloth 307 can greatly improve the service life of the breast pad. Finally, by opening the two rotating plates 310, two aromatherapy blocks 309 can be placed inside the filling sponge 304. The air pressure generated by each squeezing will cause the fragrance on the surface of the aromatherapy block 309 to leak out from the side leakage plates 303 on both sides.
