Description

Technical Field

[0001] This utility model relates to the technical field of school supplies, and more specifically to a posture corrector. Background Technology

[0002] Improper sitting posture can cause neck discomfort, hunchback, or nearsightedness. To prevent these problems and correct students' poor posture, various posture correctors have been introduced on the market. In existing posture correctors, the chest support is fixedly connected to the panel, which is placed on the table. The angle of the panel relative to the table cannot be adjusted. Otherwise, the chest support will rotate with the angle of the panel, preventing it from supporting the student's chest directly. This makes it uncomfortable to use and hinders the improvement of students' habit of looking down while studying. It also prevents the cervical spine from relaxing, which can easily lead to neck fatigue and hunchback over time. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a posture corrector that can adjust the angle of the panel relative to the desktop, while the chest support can always be placed directly on the student's chest, so that the student can look up to read and write and maintain a good learning posture. Moreover, the posture corrector can remain stable no matter how the angle of the panel is adjusted.

[0004] The technical solution of this utility model is to provide a posture corrector, including a top chest support body, a panel, and a support column; the top chest support body includes a top chest support, a top chest support column, and a base plate. The top chest support is disposed at the upper end of the top chest support column, and the lower end of the top chest support column is connected to the base plate. The base plate is used to contact the table surface on which the posture corrector is placed; one side of the panel is rotatably connected to the base plate, and the other side is connected to the support column. The support column is used to support the posture corrector on the table surface on which it is placed. The support column is retractable, and the panel can rotate relative to the top chest support body. The support column can adjust its height according to the rotation angle of the panel.

[0005] Compared with existing technologies, the posture corrector of this utility model has the following advantages: The main body of the chest support is in contact with the desktop surface via a base plate, which increases the length of the base plate and the force-bearing area of ​​the posture corrector on the desktop. When the student is leaning against the chest support, the distance between the force-bearing point of the chest support pillar on the base plate and the force-bearing point of the desktop on the base plate is long enough to prevent the chest support from tilting upwards and keep the posture corrector stable. The panel rotates relative to the base plate, and the height of the support column is adjusted in conjunction with the rotation angle of the panel. This allows the angle of the panel relative to the desktop to be adjusted, enabling students to look up while reading and writing and maintain a good learning posture. During the adjustment of the panel angle, the base plate remains stably in contact with the desktop surface, and the chest support pillar connected to the base plate remains upright on the base plate and will not rotate with the adjustment of the panel angle, ensuring that the chest support always rests directly on the student's chest for comfortable use.

[0006] Preferably, the length of the base plate is not less than 60 mm. With this structure, the length of the base plate is set to more than 60 mm. When the chest support is against the top, the distance between the force point of the top chest support pillar on the base plate and the force point of the table on the base plate is long enough to ensure that the top chest support will not tilt upwards and to keep the posture corrector stable.

[0007] Preferably, the base plate is provided with an insertion groove and a limiting member. A rotating shaft is located in the center of the insertion groove, and a rotating shaft groove is located in the center of the limiting member. Connecting holes are provided on both sides of the rotating shaft groove. The limiting member is positioned below the rotating shaft and inserted into the insertion groove. The rotating shaft is embedded downwards into the rotating shaft groove. A clearance portion is provided at the end or middle of the rotating shaft groove. The panel is provided with a first connecting portion, which includes an arc groove and two first insertion posts. The two first insertion posts are respectively inserted into two connecting holes. The arc groove and the clearance portion are vertically opposite each other, and the rotating shaft is embedded upwards into the arc groove. The limiting member and the panel can rotate on the rotating shaft. With this structure, the arc groove and the rotating shaft groove together form a structure that can rotate around the rotating shaft, meaning the limiting member and the panel can rotate on the rotating shaft. A simple structure achieves a hinged connection between the panel and the base plate.

[0008] Preferably, the base plate has two opposing, spaced-apart limiting holes on one side, with a hollow connector between them. The lower end of the top chest support pillar is connected to the upper end of the connector. An internal gear is installed inside the connector, and gear rings are provided on both the inner wall of the connector and the outer wall of the internal gear. The connector and the internal gear are connected through the meshing of the gear rings. Removable first and second plugs are respectively installed in the two limiting holes, inserting into the left and right ends of the internal gear. The two limiting holes and the first and second plugs are respectively circumferentially limited, and the first and second plugs are respectively circumferentially limited to the ends of the internal gear. With this structure, the internal gear can lock the connector, ensuring that the top chest support remains stable and does not rotate when the person leans against it during normal use. Forcibly turning the top chest support pillar can rotate the connector relative to the internal gear, thereby adjusting the angle between the top chest support and the base plate to adapt to different tabletop inclinations relative to the horizontal plane, ensuring that the top chest support always rests directly against the student's chest.

[0009] Preferably, the support column includes an outer support column and an inner support column. The inner support column is slidably connected inside the outer support column. The top end of the inner support column is connected to the panel, and the bottom end of the outer support column is used to contact the desktop where the posture corrector is placed. A locking structure is provided on the outer support column to lock the position of the inner support column on the outer support column. With this structure, the support column can be extended or retracted by sliding the inner support column inside the outer support column. The height of the support column can be adjusted by locking the position of the inner support column on the outer support column through the locking structure. Thus, a simple structure achieves the effect of adjusting the height of the support column in conjunction with the rotation angle of the panel.

[0010] Preferably, the locking structure includes an adjustment button, the middle of which is rotatably connected to the outer support column. A spring is provided between the lower part of the adjustment button and the outer support column. A locking pin is provided at the upper part of the adjustment button. The outer support column has a locking pin socket opposite to the locking pin. The inner support column has multiple slots. The locking pin passes through the locking pin socket and is inserted into any one of the slots to lock the inner support column. Pressing the lower part of the adjustment button rotates the button until the locking pin disengages from the slot, unlocking the inner support column. The spring is compressed, and its return spring resets the adjustment button. With this structure, the height of the support column can be adjusted by pressing the adjustment button, which is simple to operate. Furthermore, the number of slots can be set to determine the different height adjustment levels of the support column.

[0011] Preferably, the inner support column is equipped with a button slide, and all the slots are distributed along the button slide. A slider is located above the adjustment button, passing through the locking pin insertion port and inserting into the button slide. As the inner support column slides up and down relative to the outer support column, the slider slides along the button slide, allowing the locking pin to be inserted into any slot. With this structure, when the inner support column slides and extends within the outer support column, the slider and button slide engage smoothly, facilitating the easy insertion of the locking pin into any slot and preventing the inner support column from deflecting during sliding within the outer support column, which could prevent the locking pin from being inserted smoothly into the slot.

[0012] Preferably, multiple guide strips are provided on the left and right inner sidewalls of the outer support column. These guide strips slide in corresponding contact with the left and right outer sidewalls of the inner support column, guiding the inner support column's sliding motion within the outer support column. This structure allows the guide strips to guide the inner support column, preventing it from deflecting during sliding within the outer support column and hindering the locking pin's insertion into the slot. Furthermore, it reduces the contact area between the inner and outer support columns, decreasing friction and preventing jamming, thus ensuring smoother sliding of the inner support column within the outer support column.

[0013] Preferably, the posture corrector further includes a reading frame bracket and a reading frame. The reading frame is mounted on the reading frame bracket, and the lower end of the reading frame bracket has a connecting foot. A locking protrusion is provided on the side wall of the connecting foot, and the locking protrusion is elastically connected to the connecting foot. A third connecting cavity is provided on the lower side of the panel, and a third slide is provided within the third connecting cavity. One end of the third slide has an outwardly opening, and the side wall of the third slide is a wave-shaped limiting wall. Several limiting grooves are provided on the inner side of the wave-shaped limiting wall. The connecting foot is slidably connected to the third slide through the slide opening, and the locking protrusion can slide along the wave-shaped limiting wall and be limited by any one of the limiting grooves. With this structure, the position of the reading frame relative to the panel can be adjusted by pulling the reading frame bracket to change the upper limit position of the locking protrusion on the wave-shaped limiting wall, thereby adjusting the distance between the user's eyes and the reading material on the reading frame to accommodate different visual needs and protect the eyes.

[0014] Preferably, the reading stand is detachably connected to a reading stand bracket. The top of the reading stand has a clip for holding paper, and the bottom has a pair of page-holding strips that are rotatably connected to the bottom of the reading stand to hold down the left and right pages of a book. With this structure, the reading stand can use the clip to hold paper for drawing practice or reading documents that cannot be turned left or right, and the page-holding strips can also hold down the pages of a book for reading books or documents that can be turned left or right.

[0025] To better understand this application, various aspects of this application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0026] In the accompanying drawings, the thickness, size, and shape of the objects have been slightly exaggerated for illustrative purposes. The drawings are for illustrative purposes only and are not drawn to scale.

[0027] It should also be understood that the terms "comprising," "having," "including," and "containing," when used in this specification, indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof. Furthermore, when expressions such as "...at least one" appear after a list of listed features, they modify the entire listed feature, not individual elements in the list.

[0028] like Figure 1 and Figure 4 As shown, the posture corrector of this utility model includes a chest support body 1, a panel 2, support columns 4, a reading frame bracket 3, and a reading frame 5. The chest support body 1 includes a chest support 1-1, a chest support column 1-9, and a base plate 1-2. The chest support 1-1 is located at the upper end of the chest support column 1-9, and the lower end of the chest support column 1-9 is connected to the base plate 1-2. The base plate 1-2 is used to place on a table. One side of the panel 2 is hinged to the base plate 1-2, and the other side is connected to two support columns 4. The support columns 4 are telescopic. The panel 2 can rotate relative to the chest support body 1, and the support columns 4 can adjust their height according to the rotation angle of the panel 2.

[0029] In this way, the angle of the panel relative to the desktop can be adjusted, allowing students to look up while reading and writing, maintaining a good learning posture. The chest support will not passively rotate with the panel's angle adjustment, but will always rest directly against the student's chest, making it comfortable to use. Moreover, since the entire base plate 1-2 contacts the desktop, rather than just the chest support pillars 1-9, when a person leans against the chest support, the force arm generated by the chest support pillars on the base plate is set in the direction of the base plate's length. The length of the base plate can be increased to ensure a sufficiently long distance between the force points of the chest support pillars on the base plate and the force points of the desktop on the base plate, and a sufficiently large force-bearing area on the desktop, preventing the chest support from tilting upwards and keeping the posture corrector stable. Based on force analysis and torque calculation, in this embodiment, the length of the base plate can be set to 60 mm, 80 mm, 100 mm, or 120 mm, as long as it is 60 mm or more.

[0030] like Figure 2 and Figure 3 As shown, the base plate 1-2 is provided with two insertion slots 1-23, each containing a limiting member 1-24. A rotating shaft 1-22 is located in the middle of the insertion slot 1-23, and a rotating shaft groove 1-25 is located in the middle of the limiting member 1-24. Connecting holes 1-26 are provided on both sides of the rotating shaft groove 1-25. The limiting member 1-24 is located below the rotating shaft 1-22 and inserted into the insertion slot 1-23. The rotating shaft 1-22 is embedded downwards into the rotating shaft groove 1-25. The two connecting holes 1-26 are respectively... Located on both sides of the rotating shaft 1-22, each end of the rotating shaft groove 1-25 is provided with a clearance part 1-27; the panel 2 is provided with two first connecting parts 2-1, each first connecting part 2-1 including a pair of opposing arc grooves 2-2 and two first insertion posts 2-3. The panel 2 is located above the base plate 1-2, and the two first insertion posts 2-3 are respectively inserted into the two connecting holes 1-26. The arc grooves 2-2 and the clearance parts 1-27 are vertically opposite each other, and the rotating shaft 1-22 is embedded upward into the arc grooves 2-2.

[0031] Thus, the arc groove 2-2 and the rotating shaft groove 1-25 together form a structure that can rotate around the rotating shaft 1-22. The combination of the limiting member 1-24 and the panel 2 can rotate on the rotating shaft 1-22, realizing the hinge connection between the panel 2 and the base plate 1-2.

[0032] like Figure 4 As shown, two opposing limiting holes 1-21 are provided on one side of the base plate 1-2. A hollow connector 1-7 is provided between the two limiting holes 1-21. The lower end of the top chest support pillar 1-9 is connected to the upper end of the connector 1-7. A connector housing 1-6 is provided above the connector 1-7. A connector base 1-8 is provided below the connector 1-7. The connector housing 1-6 and the connector base 1-8 are mated to protect the connection position between the top chest support pillar 1-9 and the connector 1-7. The connector 1-7 is equipped with an internal gear 1-5. Both the inner sidewall of the connector 1-7 and the outer sidewall of the internal gear 1-5 are equipped with gear rings. The connector 1-7 and the internal gear 1-5 are connected by meshing with the corresponding gear rings. The two limiting holes 1-21 are respectively equipped with a detachable first plug 1-3 and a second plug 1-4. The first plug 1-3 and the second plug 1-4 are respectively inserted into the left and right ends of the internal gear 1-5. The two limiting holes 1-21 and the first plug 1-3 and the second plug 1-4 are respectively circumferentially limited and engaged. The first plug 1-3 and the second plug 1-4 are respectively circumferentially limited and engaged with the ends of the internal gear 1-5.

[0033] Thus, the internal gear 1-5 is locked to the base plate 1-2 via the first plug 1-3 and the second plug 1-4. Since the internal gear 1-5 and the connector 1-7 are connected by a gear ring meshing, the internal gear 1-5 can lock the connector 1-7, ensuring that the posture corrector remains stable and does not rotate when the person leans against the chest support during normal use. However, forcefully turning the chest support support pillar 1-9 will cause the connector 1-7 to rotate relative to the internal gear 1-5, thereby adjusting the angle between the chest support 1-1 and the base plate 1-2 to adapt to different inclinations of the desktop relative to the horizontal plane, ensuring that the chest support always rests facing the student's chest.

[0034] like Figure 5 and Figure 6As shown, the support column 4 includes an outer support column 4-1 and an inner support column 4-2. The inner support column 4-2 is slidably connected to the outer support column 4-1. Multiple guide strips 4-15 are provided on the left and right inner sidewalls of the outer support column 4-1. The guide strips 4-15 slide in corresponding contact with the left and right outer sidewalls of the inner support column 4-2, guiding the inner support column 4-2's sliding movement within the outer support column 4-1. An upper limit groove 4-21 is provided at the top of the inner support column 4-2, and a positioning hole 4-22 is provided in the middle of the upper limit groove 4-21. A second connecting part 2-4 is provided on the lower side of the panel 2. The second connecting part 2-4 includes a second connecting column 2-5 and a second insertion ring 2-6 surrounding the second connecting column 2-5. The second insertion ring 2-6 is inserted into the upper limit groove 4-21, and the second connecting column 2-5 is correspondingly inserted into the positioning hole 4-22. This achieves the connection between the support column 4 and the panel 2.

[0035] A locking structure is provided on the outer support column 4-1. The locking structure includes an adjustment button 4-5. The outer support column 4-1 is provided with a button mounting part 4-11. The adjustment button 4-5 has two pivot connection holes 4-53 in the middle. The button mounting part 4-11 has two pivot holes 4-13 in the middle. A pivot is inserted into the pivot connection holes 4-53 and the pivot holes 4-13, so that the middle part of the adjustment button 4-5 is rotatably connected to the outer support column 4-1.

[0036] The upper part of the adjustment button 4-5 is provided with a locking post 4-51, and the lower part of the locking post 4-51 is provided with a slider 4-52. The upper part of the button mounting part 4-11 is provided with a locking post socket 4-14 opposite to the locking post 4-51 and the slider 4-52. The inner support post 4-2 is provided with a button slide 4-23 opposite to the locking post socket 4-14. The button slide 4-23 is provided with three slots 4-24 along its length. The lower end of the button slide 4-23 is closed.

[0037] The lower part of the adjustment button 4-5 is provided with a spring groove 4-54, and the lower part of the button mounting part 4-11 is provided with a spring limiting post 4-12. The spring groove 4-54 and the spring limiting post 4-12 together form a spring seat. A spring is provided in the spring seat. The elastic force of the spring causes the locking post 4-51 and the slider 4-52 to be inserted into the locking post socket 4-14, and causes the slider 4-52 to be inserted into the button slide 4-23. It also allows the locking post 4-51 to be inserted into any of the slots 4-24 to lock the inner support post 4-2. A limiting protrusion 4-16 is also provided on the inner sidewall of the outer support column 4-1, opposite to the locking pin socket 4-14. The limiting protrusion 4-16 abuts against the rear sidewall of the inner support column 4-2, causing the inner support column 4-2 to move closer to the locking pin socket 4-14. In this way, the button slide 4-23 will not disengage from the slider 4-52, and the locking pin 4-51 can be inserted into the slot 4-24 at any time. A rear sliding groove can be provided on the rear sidewall of the inner support column 4-2 to slide and engage with the limiting protrusion 4-16. When the inner support column 4-2 slides and extends within the outer support column 4-1, the limiting protrusion 4-16 slides within the rear sliding groove, guiding and limiting the inner support column 4-2.

[0038] Pressing the lower part of the adjustment button 4-5 will rotate the adjustment button 4-5 until the locking pin 4-51 exits the slot 4-24, unlocking the inner support pin 4-2. The spring is compressed, and the spring rebound will reset the adjustment button 4-5. However, regardless of whether the adjustment button 4-5 is pressed or not, the slider 4-52 will always be inserted into the button slide 4-23.

[0039] When the inner support column 4-2 slides and extends within the outer support column 4-1, the slider 4-52 slides and engages with the button slide 4-23, allowing the locking column 4-51 to smoothly insert into any slot 4-24. This prevents the inner support column 4-2 from deflecting and jamming when it slides within the outer support column 4-1. The closed lower end of the button slide 4-23 prevents the slider 4-52 from slipping off the button slide 4-23, thus preventing the inner support column 4-2 from detaching from the outer support column 4-1.

[0040] like Figure 7 and Figure 8As shown, the upper end of the reading holder bracket 3 is provided with a reading holder slot 3-3, into which the reading holder 5 is inserted. The lower end of the reading holder bracket 3 is provided with a pair of insertion feet 3-1, and the side wall of the insertion feet 3-1 is provided with a locking protrusion 3-2, which is elastically connected to the insertion feet 3-1. The lower side of the panel 2 is provided with two third connecting cavities 2-7, the bottom of the third connecting cavity 2-7 is provided with a cover plate 2-8, and a guide plate 2-12 is also provided inside the third connecting cavity 2-7. A third slide 2-9 is provided between the plate 2-12 and the cover plate 2-8. The rear part of the panel 2 has an externally open slide opening 2-11 at one end of the third slide 2-9. The cover plate 2-8 has a side wall of the third slide 2-9, which is a wave-shaped limiting wall 2-10. The inner side of the wave-shaped limiting wall 2-10 has several limiting grooves. The plug-in foot 3-1 is slidably connected to the third slide 2-9 through the slide opening 2-11. The locking protrusion 3-2 can slide along the wave-shaped limiting wall 2-10 and be limited by any one of the limiting grooves.

[0041] The position of the reading stand 5 relative to the panel 2 can be adjusted by pulling the reading stand bracket 3 to change the upper limit position of the locking protrusion 3-2 on the wave-limiting vertical wall 2-10, thereby adjusting the distance between the human eye and the reading material on the reading stand 5 to adapt to the needs of different vision and protect the eyes.

[0042] like Figure 9 As shown, the top of the reading holder 5 is equipped with a clip 5-1 for holding paper, and the bottom of the reading holder 5 is equipped with a pair of page clamps 5-2. The page clamps 5-2 are rotatably connected to the bottom of the reading holder 5. The reading holder 5 is provided with clamping grooves 5-3 corresponding to the page clamps 5-2. The page clamps 5-2 can rotate and fit into the corresponding clamping grooves 5-3 for easy storage. The page clamps 5-2 can be rotated out of the clamping grooves 5-3 to press down the left and right pages of a book. In this way, the reading holder 5 can use the clip 5-1 to hold paper, which is convenient for drawing practice or reading documents that cannot be turned left and right, and can also use the page clamps 5-2 to press down the pages of a book, which is convenient for reading books or documents that can be turned left and right.

[0043] In other embodiments, the reading stand 3 and reading stand 5 may not be provided. The user can read and write on the panel 2. Since the person can keep their upper body upright and maintain the distance from the reading and writing materials on the panel 2 when leaning against the chest support, a good learning posture can also be maintained.

[0044] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
