Description

Technical Field

[0001] The present technical solution relates to the technical field of correction tools, and in particular to a reading and writing assisting device. Background Art

[0002] A reading and writing assistive device is an assistive device designed to help users improve and maintain correct posture. In particular, sitting posture correction devices can help users improve their sitting posture and cultivate good reading and writing habits.

[0003] For example, Chinese patent CN215076419U discloses a sitting posture correction device, including a lifting bracket assembly, a fastening assembly and a positioning adjustment assembly. The lifting bracket assembly includes a protective cover and a lifting member. A button mechanism is arranged between the adjustment bracket and the fastening assembly. The button mechanism is fixed to the button seat by elastic snap connection. The height of the protective support part can be adjusted by unidirectional movement. When descending, it can be lowered by slightly pulling it.

[0004] The above-mentioned sitting posture correction device adjusts the height position of the protective cover through the lifting bracket assembly to adapt to the body posture differences of different people. The principle of the existing correction device is to block the incorrect sitting posture of the human body with the upper body leaning forward through the correction assembly. The protective cover needs to fit the chest. The current protective cover has a poor adhesion effect. Long-term use causes strong discomfort, resulting in low comfort and poor applicability, which needs to be improved. Summary of the invention

[0005] In order to improve the problem of poor applicability caused by poor adhesion of the protective cover, the present technical solution provides a reading and writing auxiliary device.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A reading and writing assisting device comprises a table panel and a lifting mechanism arranged on the table panel. The table panel is used to lean against a table top. A supporting frame is arranged at one end of the lifting mechanism. The lifting mechanism can place the supporting frame at different heights. The supporting frame has an elastic supporting portion, which extends outward to form an elastic buffer.

[0008] Through the above technical solution, when the reading and writing assistive device is used normally, the table panel is placed on the table so that it is flat and firmly against the table for reading and writing. The support frame is positioned close to the user, and the support frame is adjusted to different heights through a lifting mechanism. In order to meet the needs of different human body heights, postures and sitting habits, the comfort and applicability are improved by adjusting the appropriate height.

[0009] The elastic support portion extends in the direction in which the human body leans. Based on the elastic deformation ability of the elastic support portion, when the chest rests against the elastic support portion, the elastic support portion deforms accordingly to achieve an angle that matches the chest contour, and has good resilience and buffering effects, providing the necessary supporting force. The height and angle adjustment help to maintain the correct reading and writing posture, further improving the comfort level and further improving the applicability.

[0010] Preferably, the supporting frame is provided with a supporting pad, one side of the supporting pad has a flexible portion, and the flexible portion is arranged to protrude outward relative to the supporting pad.

[0011] Through the above technical solution, the support frame is additionally installed with a support pad, which is used for cushioning. The flexible part of the support pad is filled with flexible material to provide a softer and more comfortable touch. It deforms to support the chest area that needs support, effectively relieves the pressure and fatigue caused by long-term use, and improves comfort.

[0012] The protruding design of the flexible part increases the contact area between the supporting pad and the abutting part, and the protruding setting has more deformable amounts, making the supporting effect after deformation more uniform and stable, thereby further improving applicability.

[0013] Preferably, a first arc surface portion and a second arc surface portion are provided on the top of the supporting pad, a groove is provided between the first arc surface portion and the second arc surface portion, and the curvature of the first arc surface portion is smaller than the curvature of the second arc surface portion.

[0014] Through the above technical solution, the groove is formed at the upper end of the support pad along the edge through the first arc surface portion and the second arc surface portion. The support pad with the groove has a natural barrier to prevent children from mistakenly resting their chin on the support pad during use, thereby standardizing the sitting posture and promoting better sitting habits.

[0015] Preferably, the front side of the table panel has a limit plate, and the lifting mechanism is separately arranged on the limit plate.

[0016] Through the above technical solution, when the table top is against the table top, it can be against the side of the table top, which is used to limit the table top from moving forward on the table top after being stressed, thereby ensuring the stability of the table top during use.

[0017] The lifting mechanism is separately arranged on the limit plate. The separate design makes it easier to maintain and replace the lifting mechanism when necessary, thereby improving the flexibility of assembly.

[0018] Preferably, the lifting mechanism comprises an adjusting rod and a fixing seat, one end of the adjusting rod is arranged on the fixing seat, and the other end is provided with the supporting frame;

[0019] The upper end surface of the fixing seat is lower than the table panel, and when the adjusting rod is retracted, the supporting bracket can abut against the fixing seat.

[0020] Through the above technical solution, the adjustment rod has a telescopic adjustment function. By pulling the support bracket upward, the adjustment rod is stretched accordingly, so that the support bracket is lifted. By pressing the support bracket downward, the compression and stretching rod can be adjusted to lower the support bracket. When the adjustment rod is in a fully retracted state, the adjustment height of the support bracket is at the lowest point. At this time, the support bracket is close to the fixed seat and is in a storage state. Based on the fact that the upper end surface of the fixed seat is lower than the table panel, the protrusion of the upper end surface of the support bracket relative to the table panel is reduced, and the additional space occupation is reduced, thereby reducing interference with reading and writing operations, and further improving comfort.

[0021] Preferably, the limiting plate is provided with a clamping block, two clamping blocks are provided, and the two opposite sides between the two clamping blocks are provided with limiting protrusions;

[0022] The fixing seat is provided with two connecting grooves, the positions of the two connecting grooves correspond to the two card embedding blocks one by one, and are used for the card embedding blocks to be embedded;

[0023] The connecting groove includes an embedding groove and a limiting groove, wherein the limiting groove is arranged on the inner wall of the embedding groove. When the embedding block is embedded in the embedding groove, the embedding block translates along the embedding groove so that the limiting protrusion is embedded in the limiting groove to achieve limiting.

[0024] Through the above technical solution, the fixed seat is installed close to the limiting plate, and the two connecting grooves of the fixed seat are aligned one by one with the two card blocks on the limiting plate. The card blocks are adapted to the connecting grooves so that the two card blocks are embedded in the corresponding two connecting grooves. Based on the connection between the embedding groove in the connecting groove and the limiting groove, the downward movement of the fixed seat enables the card blocks to move along the embedding groove toward the limiting groove, and the limiting protrusion is translated into the limiting groove through the connection, and is firmly embedded in the limiting groove for positioning, thereby realizing that the card blocks are locked in the connecting groove, increasing the stability of the connection, and the installation process is simpler and faster, thereby improving the installation efficiency.

[0025] Preferably, the limiting plate is formed with a mounting groove, the mounting groove is matched with the fixing seat, and the embedding block is arranged on the inner wall of the mounting groove.

[0026] Through the above technical solution, the installation groove is adapted to the fixing seat, and the card block is fixed on the inner wall of the installation groove, so that the fixing seat can be embedded in the installation groove for fixed installation with better accuracy, and the relative side walls of the installation groove improve the positioning of the fixing seat.

[0027] Preferably, the spacing between the side of the supporting pad facing away from the table top and the limiting plate is 60 mm-90 mm.

[0028] Through the above technical solution, during the lifting process, the supporting pad moves up and down relative to the tabletop, but the distance between the supporting pad and the tabletop in the horizontal direction is equidistant. The distance between the supporting pads is limited within a certain range, so that there is always a distance of about one fist between the user and the tabletop, maintaining a distance from the tabletop, making the eye-using distance more standardized.

[0029] Preferably, the shape of the tabletop is fan-shaped.

[0030] Through the above technical solution, the shape of the tabletop is set as a fan shape, so that the writing area of the fan-shaped area is more suitable for the activity range of the human arm, making the writing area more spacious and making full use of the writing area.

[0031] Preferably, the tabletop has a front support plate, and the front support plate has an arc surface, and the arc surface is in a circular arc transition downward relative to the upper end surface of the tabletop;

[0032] The included angle between the limiting plate and the tabletop is 90°;

[0033] The adjusting rod includes three or more inner rods sleeved in sequence;

[0034] The supporting bracket is in a "mouth" shape, and the upper part of the supporting bracket bends and extends toward one side of the tabletop; the supporting pad is clamped on the elastic support part of the supporting bracket; in the folded state, the upper end of the supporting bracket is lower than the tabletop, and the height of the upper end of the supporting pad is lower than the tabletop;

[0035] A long strip-shaped groove is provided on the front side of the tabletop.

[0036] Through the above technical solution, a front support plate with an arc surface is added. The front support plate is integrally provided with the tabletop, and the arc surface and the upper end surface of the front support plate are smoothly and naturally transitioned, reducing the pressure on the arm caused by the corners of the tabletop, better fitting the arm resting part, improving comfort. The long strip-shaped groove is provided on the front side of the tabletop, so that when the pen rolls along the tabletop, it is stuck in the groove to limit its continuous rolling, effectively preventing the pen from falling to the ground and being damaged, and reducing the process of picking up the pen, making the work smoother.

[0037] At least three inner rods are sleeved in sequence to form an adjusting rod, enabling multi-stage adjustment. By increasing or decreasing the number of inner rods, the range of adjustable height can be controlled, improving the practicality of adjustment. The included angle between the limiting plate and the tabletop is 90°, and the limiting plate is vertically arranged, further improving the stability of the tabletop during use; the "mouth"-shaped supporting bracket makes the structure more stable, improving the structural strength. In the folded state, the upper ends of the supporting bracket and the supporting pad are both lower than the tabletop, so that their upper end surfaces cannot protrude relative to the tabletop, thereby further reducing the interference with the reading and writing operations.

[0038] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0039] 1. This technical solution is to set a lifting mechanism on the table panel, which can adjust the support frame to different heights. The support frame extends with an elastic support part in the direction of human body leaning. The elastic support part has good resilience and buffering effect. It can reach an angle suitable for the chest cavity when it is against the support through deformation, provide stable support force, and improve applicability.

[0040] 2. This technical solution is provided with a supporting pad through a supporting frame. One side of the supporting pad has a flexible part, which provides a softer and more comfortable touch. The deformation supports the supported chest area, effectively relieves the pressure and fatigue caused by long-term use, and improves comfort. The flexible part is convex outward relative to the supporting pad, so that the supporting effect is more uniform and stable, and the applicability is further improved;

[0041] 3. This technical solution provides a groove at the upper end of the support pad along the edge. The groove makes the edge of the upper end of the support part uneven, and the user's chin is placed on the support pad to regulate the sitting posture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0049] Example:

[0050] See also Figure 1 A reading and writing assisting device comprises a table panel 1, which has a specific shape and can be square, fan-shaped or circular, preferably fan-shaped. The table panel 1 can be placed against a table top, and the table panel 1 has a limiting plate 13, which is arranged corresponding to the straight line segment on the front side of the table panel 1 and is fixed under the table panel 1. The limiting plate 13 shown in this embodiment is arranged perpendicular to the table panel 1, so that the angle between the two is 90°. The angle formed between the limiting plate 13 and the table panel 1 is adapted to the corner of the table top, so that the stability of the table top when placed on the table top is improved by the cooperation and abutment.

[0051] See also Figure 2 and Figure 3 The table panel 1 is provided with a lifting mechanism 2, which includes an adjusting rod 21 and a fixing seat 22. The lower end of the adjusting rod 21 is fixed to the upper end of the fixing seat 22. The adjusting rod 21 shown in this embodiment is made of aluminum alloy and has a telescopic rod structure for infinite adjustment. The adjusting rod 21 includes a plurality of inner rods 17. The adjusting rod includes more than three inner rods, and the plurality of inner rods 17 are arranged in sequence. In this embodiment, the adjusting rod 21 includes five inner rods 17, so that the adjusting rod 21 can be retracted or extended, thereby achieving a certain damping feeling or locking mechanism in different height ranges to achieve multi-stage graded adjustment.

[0052] The limiting plate 13 is recessed with a mounting groove 7 adapted to the fixing seat 22 . The mounting groove 7 is arranged relative to the middle part of the limiting plate 13 and faces the direction of the user. The fixing seat 22 can be embedded in the mounting groove 7 , and the upper end surface of the fixing seat 22 is lower than the upper end surface of the table panel 1 .

[0053] The fixing seat 22 and the limiting plate 13 are arranged separately. The specific detachable connection method is that two card-embedded blocks 4 are provided on the limiting plate 13. The two card-embedded blocks 4 are fixed to the inner wall of the installation groove 7. They are arranged at intervals along the length direction of the limiting plate 13. The relative side walls between the two fixing blocks are protruded with limiting protrusions 5. The two limiting protrusions 5 are oriented opposite to each other. The end face of one side of the fixing seat 22 close to the installation groove 7 is provided with two connecting grooves 6. The positions of the two connecting grooves 6 correspond to the two card-embedded blocks 4 one by one. The connecting groove 6 includes an embedding groove 61 and a limiting groove 62. The limiting groove 62 is arranged on the inner wall of the embedding groove 61 so that it is connected to the lower groove. The shape and size of the embedding groove 61 are adapted to the card-embedded block 4. After the fixing seat 22 is embedded in the fixing groove, the two card-embedded blocks 4 are embedded in the corresponding two embedding grooves 61. The fixing seat 22 moves downward along the installation groove 7, and the card-embedded block 4 translates in the embedding groove 61 in the opposite direction until the limiting protrusion 5 is embedded in the limiting groove 62 to achieve limiting.

[0054] See also Figure 2 and Figure 4 One end of the lifting mechanism 2 is provided with a supporting bracket 3. The supporting bracket 3 is in a "mouth" shape. The upper part of the supporting bracket 3 bends and extends towards one side of the table board 1. It is installed at the upper end of the adjusting rod 21. An embedding hole for the upper end of the adjusting rod 21 to be embedded is formed on the lower end face of the supporting bracket 3 to achieve fixation. When the adjusting rod 21 is completely retracted into the fixed seat 22, the supporting bracket 3 can abut against the upper end face of the fixed seat 22. When the adjusting rod 21 extends, different adjustment heights of the adjusting rod 21 correspond to different height positions of the supporting bracket 3, improving the height adaptability.

[0055] The supporting bracket 3 has an elastic support part 14. The elastic support part 14 extends outwards, and the extending part is in an arc transition and guides to the side where the user abuts. The elastic support part 14 has the ability of elastic deformation adjustment for elastic buffering when used for abutting; The supporting bracket 3 is provided with a supporting pad 8. The supporting pad 8 is located on the front side of the supporting bracket 3. The supporting pad 8 is bolted to the elastic support part 14. The top of the supporting pad 8 is provided with a first arc surface part 15 and a second arc surface part 16. The radian of the first arc surface part 15 is smaller than that of the second arc surface part 16. An included angle is formed between the first arc surface part 15 and the second arc surface part 1, and this included angle is a groove 10. In this embodiment, the situation where a plurality of grooves 10 are arranged along the circumferential side of the supporting pad 8 is shown. The cooperation of the plurality of grooves 10 makes the shape of the supporting pad 8 present a cloud shape.

[0056] One side of the supporting pad 8背离 the elastic support part 14 has a flexible part 9, which is fixed to the supporting pad 8. The flexible part 9 has a filler inside and is preferably made of sponge, having good resilience and softness. The flexible part 9 protrudes outwards relative to the supporting pad 8.

[0057] See Figure 5 When the supporting bracket 3 abuts against the fixed seat 22, there is a distance between the end face of the supporting pad 8背离 the table board 1 and the limiting plate 13. The interval distance α = 60mm - 90mm, preferably 75mm, which is equivalent to the distance of one punch. When the supporting bracket 3 is lifted, its interval distance in the horizontal direction always remains unchanged.

[0058] The table board 1 also has a front supporting board 11. The front supporting board 11 is located on the side of the table board 1 where the limiting plate 13 is provided. The front supporting board 11 has an arc surface 12. The arc surface 12 is connected with the upper end face of the table board 1. The arc surface 12 is in an arc transition downwards relative to the upper end face of the table board 1. The front supporting board 11 leaves a space corresponding to the position of the lifting device. A long strip-shaped groove 18 is arranged on the front side of the table board 1. The groove 18 is recessed relative to the upper end face of the table board 1. The length direction of the groove 18 is parallel to the fan-shaped straight line segment of the table board 1.

[0059] The specific working process of this solution is as follows:

[0060] The present technical solution is to coordinate the table panel 1 and the limit plate 13 to be flat and firmly against the table top, the support frame 3 is positioned close to the user, and the support frame 3 is adjusted to different heights through the lifting mechanism 2. In order to meet the needs of different human body heights, body shapes and sitting habits, the appropriate height is adjusted, and the elastic support part 14 extends in the direction in which the human body leans. Based on the elastic deformation ability of the elastic support part 14, when the chest cavity rests on the elastic support part 14, the elastic support part 14 is deformed accordingly to achieve an angle adapted to the chest cavity contour, and has good resilience and buffering effect, providing the necessary supporting force. The height and angle adjustment are coordinated to help maintain a correct reading and writing posture, further improving the comfort level and further improving the applicability.

[0061] The above shows and describes the basic principle and main features of the technical solution and the advantages of the technical solution. The technicians in this industry should understand that the technical solution is not limited by the above embodiments.
