Description

Technical Field

[0001] This application relates to the field of learning assistance equipment technology, and in particular to a multifunctional posture corrector. Background Technology

[0002] Currently, the market offers posture correction products placed on desktops to assist in adjusting sitting posture during study. These posture correctors typically include a tabletop, which serves as the primary support surface for students and features an adjustable tilt angle. By adjusting the tabletop's tilt angle, students can find the most suitable posture for different learning scenarios, such as writing or drawing, avoiding hunching and reducing fatigue from maintaining the same posture for extended periods. In related technologies, to further meet students' needs for reading books, reading supports are installed on the tabletop. These reading supports are usually fixedly connected to the tabletop or mounted on it via a specific connection structure. Their function is to assist in placing books, allowing students to read at a more suitable angle and distance, reducing strain on the neck and eyes. Because reading supports are closely integrated with the tabletop and must be used in conjunction with it, they cannot be used independently as a reading aid, resulting in limited flexibility in their use.

[0026] This invention proposes a multifunctional posture corrector for use on a desktop.

[0027] In this embodiment of the utility model, please refer to Figures 1 to 5 The multifunctional posture corrector includes a desktop support 100 and a reading stand 200. The desktop support 100 has a drawing desktop 110 and a supporting base 120 arranged at an angle. The drawing desktop 110 is used to support books when writing, and the supporting base 120 is used to place it on a desk. The side of the desktop support 100 facing away from the drawing desktop 110 has a connecting part 130. The reading stand 200 includes a rotatably connected supporting base 210 and a reading board 220. The supporting base 210 can be used to place it on a desk to support the reading stand 200. The supporting base 210 is detachably fixed to the connecting part 130 so that the reading board 220 can rotate relative to the drawing desktop 110 to adjust its angle. The surface of the reading board 220 near the drawing desktop 110 has a side guard assembly 230.

[0028] In this embodiment, the learning and drawing desktop 110 refers to an inclined working surface that supports books and provides support for the user's arms, enabling them to study, write, or draw on the desktop support 100. For ease of study, the learning and drawing desktop 110 is typically designed to be flat. The supporting base 120 contacts the desk surface to provide support for the desktop support 100. Specifically, the supporting base 120 can be made of rubber, silicone pads, etc., to increase friction. The learning and drawing desktop 110 and the supporting base 120 are set at an angle, meaning that the learning and drawing desktop 110 is tilted relative to the desk surface during use. The angle between the learning and drawing desktop 110 and the supporting base 120 can be set to a fixed value or be adjustable. For example, by including a tabletop 150 and an adjustment frame with a back surface of the tabletop 150 in the desktop support 100, the tilt angle of the tabletop 150 can be adjusted via the adjustment frame to meet the needs of different users.

[0029] The connecting part 130 is located on the back of the desktop stand 100 to avoid occupying the area of ​​the drawing desktop 110 and to keep the front of the desktop stand 100 clean. The connecting part 130 is used for quick assembly and disassembly of the support base 210 of the reading stand 200. The connecting part 130 can be integrated with the tabletop 150 or set as a structure independent of the tabletop 150. There are many ways to detach the support base 210 and the connecting part 130. For example, they can be connected by plugging, magnetic connection, snap-fit, etc., to facilitate quick assembly and disassembly. The specific detachable fixing method of the support base 210 and the connecting part 130 is not limited here.

[0030] Specifically, the desktop stand 100 is stably placed on the desk via the support base 120, and the drawing desktop 110 forms an ergonomically inclined writing support surface to adjust the user's posture. When reading is needed, the support base 210 of the reading stand 200 is quickly installed by connecting the connector 130. By making the support base 210 and reading board 220 of the reading stand 200 rotatably connected, the reading position can be adjusted by rotating the reading board 220 to meet different reading angle requirements. The support base 210 and reading board 220 can use a hinge structure with damping elements to achieve multi-angle positioning. The side guard assembly 230 is a limiting device to prevent books or tablets from slipping off, and can specifically adopt a structure combining a rotatable clamping arm and a horizontal stop bar 231.

[0031] The support base 210 can be a single support plate, a support arm, or a support frame, etc. It simply needs to ensure that the height of the support base 210 (its width in the front-to-back direction when used alone) is greater than half the height of the reading board 220 (its width in the vertical direction when used alone), providing stable support for the reading board 220 when rotated to a preset angle. The specific structure of the support base 210 is not limited here. The support base 210 can be combined with the connecting part 130, allowing the reading stand 200 to be used as an extension module of the desktop stand 100. Furthermore, after the reading stand 200 is detached from the desktop stand 100, it provides stable support for the reading stand 200, allowing it to be placed independently on a desktop, thus increasing the product's usability.

[0032] This utility model's multi-functional posture corrector, by providing a connecting part 130 on the back of the desktop support 100, avoids occupying the area of ​​the study desktop 110, thus maintaining the integrity and neatness of the front of the desktop support 100. The support base 210 of the reading stand 200 is detachably connected to the connecting part 130, and the support base 210 can be placed on a desk to support the reading stand 200. Therefore, the reading stand 200 can serve as both a reading extension module for the multi-functional posture corrector and a stand-alone reading device on a desktop, allowing users to choose to use it in combination or individually according to their needs, thus improving the flexibility of the reading stand 200. Furthermore, by rotatably connecting the reading board 220 of the reading stand 200 to the support base 210, the reading angle of the reading board 220 is adjustable. Combined with the side panel assembly 230, it can adapt to various usage scenarios, significantly improving the product's practicality.

[0033] In one embodiment, such as Figure 2 and Figure 3 As shown, the connecting part 130 is provided with a plug groove 131 extending along the drawing table 110 and having an opening on the top side, and the support base 210 is plugged into the plug groove 131 through the opening.

[0034] In this embodiment, the insertion groove 131 refers to a guide structure extending along the drawing tabletop 110 and having an opening at the top, specifically a U-shaped groove or a T-shaped groove structure. The support base 210 is inserted into the insertion groove 131 along the extension direction of the drawing tabletop 110, rather than perpendicularly to the drawing tabletop 110. In this way, the support base 210 can remain aligned with the drawing tabletop 110 after insertion, reducing the space occupied by the support base 210 and effectively preventing the support base 210 from falling off. The depth of the insertion groove 131 can be set to 1.1-1.5 times the thickness of the support base 210, which can ensure the stability of the insertion and facilitate manual operation. To reduce friction, the connecting part 130 optionally includes two opposing slide rails, with the connecting part 130 hollowed out between the two slide rails. The slide rails have insertion grooves 131 formed inside them, and the two sides of the support base 210 are inserted into the two slide rails. In this way, the support base 210 only contacts the groove wall of the insertion slot 131 on both sides, which can effectively reduce the insertion and extraction friction of the support base 210 in the insertion slot 131.

[0035] In this embodiment, by inserting the support base 210 into the insertion slot 131 along the extension direction of the drawing table 110, the support base 210 and the connecting part 130 can be quickly positioned and disassembled, while minimizing the space occupied by the support base 210. This makes the overall structure more compact and occupies less space after the support base 210 and the connecting part 130 are combined.

[0036] Specifically, in the direction of the insertion plate of the support base 210, the extension length of the support base 210 is greater than half the height of the reading plate 220. Thus, after the reading stand 200 is detached from the desktop stand 100, the support base 210 can provide stable support for the reading stand 200, allowing the reading stand 200 to be placed on the desktop for use independently.

[0037] Further, please refer to Figure 2 , Figure 3 , Figures 9 to 13 The connecting part 130 is also provided with a locking member 132, which can be switched between a locked position and an unlocked position. In the locked position, the locking member 132 extends into the insertion groove 131 and engages with the support base 210. In the unlocked position, the locking member 132 disengages from the support base 210 so that the support base 210 can be pulled out from the insertion groove 131.

[0038] The locking element 132 is a structure used to limit the displacement of the support base 210 relative to the insertion slot 131. Specifically, the locking element 132 can be a snap-fit ​​structure with an elastic reset function, achieving switching between the locked and unlocked positions through elastic deformation. Depending on actual needs, the locking element 132 can be designed to rotate or move to switch between the locked and unlocked positions. In the locked position, the locking element 132 partially extends into the insertion slot 131 and engages with the support base 210, locking the support base 210 within the insertion slot 131 and preventing the stop base from moving along the insertion plate direction, thus preventing the support base 210 from detaching. When it is necessary to disassemble the reading bracket 200, by switching the locking element 132 to the unlocked position, the locking element 132 disengages from the support base 210, releasing the constraint on the support base 210, at which point the support base 210 can be pulled out from the insertion slot 131. This solution uses a locking element 132 on the connecting part 130 to engage with the support base 210, ensuring a stable connection between the support base 210 and the reading bracket 200 while enabling quick disassembly without the need for tools.

[0039] Furthermore, the support base 210 is plate-shaped, and the support base 210 has a slot 211 in the middle of the first direction, which is perpendicular to the insertion and removal direction of the support base 210. The desktop stand 100 also includes an elastic element 140, and the locking element 132 includes a pressing part 133 and a locking part 134 connected to each other. The pressing part 133 is rotatably connected to the connecting part 130 and elastically abuts against the connecting part 130 by the elastic element 140. The locking part 134 is located in the insertion groove 131 and is adapted to engage with the groove 211.

[0040] In this embodiment, the support base 210 is plate-shaped, allowing the reading stand 200 to be stably placed on a desk surface for use as an independent stand. The elastic element 140 provides elastic restoring force to the pressing part 133; this elastic element 140 can specifically be a compression spring or an elastic rubber block. By rotatably connecting the locking element 132 to the connecting part 130, and by elastically abutting the pressing part 133 against the connecting part 130 via the elastic element 140, the locking part 134 can be automatically locked. Specifically, when the support base 210 is inserted into the insertion slot 131, the locking part 134 is first pushed up, and then the elastic restoring force causes the locking part 134 to automatically engage with the slot 211 of the support base 210, achieving mechanical interlocking between the support base 210 and the locking element 132, preventing the support base 210 from detaching from the insertion slot 131. When the reading bracket 200 needs to be disassembled, the user manually presses the pressing part 133 to overcome the elastic force of the elastic element 140. When the pressing part 133 rotates under force, it causes the engaging part 134 to disengage from the slot 211, achieving quick unlocking. At this time, the support base 210 can be pulled out from the insertion slot 131. By manually pressing to unlock the locking element 132, the locking and unlocking process of the locking element 132 is less strenuous and the operation is more convenient.

[0041] In one embodiment, such as Figure 2 , Figure 3 , Figure 12 and Figure 13 The desktop stand 100 includes a tabletop 150, the front of which forms a drawing desktop 110. A connecting part 130 is detachably mounted to the back of the tabletop 150. By providing an additional connecting part 130, instead of slotting the tabletop 150 to fix the support base 210, the strength and integrity of the tabletop 150 are avoided, further improving the product's performance. Furthermore, since the connecting part 130 needs to bear the load of the reading bracket 200, it is prone to damage. By making the connecting part 130 detachable from the tabletop 150, it can be replaced individually when damaged, reducing replacement and repair costs compared to replacing the entire tabletop 150. Specifically, the connecting part 130 can be detachably fixed to the back of the tabletop 150 using screws, bolts, etc. The tabletop 150 and the connecting part 130 can be made of different materials; for example, the tabletop 150 can be made of wood to improve product quality, while the connecting part 130 can be made of plastic to reduce cost and weight.

[0042] In one embodiment, please refer to Figures 5 to 8 The support base 210 has multiple stop grooves 212 on one side of the back of the reading plate 220; the reading bracket 200 also includes a support member 240, the upper end of which is rotatably connected to the back of the reading plate 220, and the lower end which is switchably placed in one of the multiple stop grooves 212 to adjust the angle of the reading plate 220 relative to the support base 210.

[0043] The support member 240 is a movable component rotatably connected to the reading plate 220. The support member 240 can be a support plate, support rod, support frame, etc. The lower end of the support member 240 cooperates with the stop groove 212 to provide stable support for the reading plate 220. The stop groove 212 is a recessed structure located on the back of the support base 210 to define the position of the support member 240. Specifically, it can be a rectangular groove, an arc-shaped groove, or a stepped groove, and its quantity can be three, five, or other quantities. Multiple stop grooves 212 are arranged side-by-side on the support base 210 along the direction towards the reading plate 220. The spacing between adjacent grooves can be set according to angle adjustment requirements; for example, a 10mm interval corresponds to a 5° tilt angle change. By providing multiple stop grooves 212 on the support base 210, the support member 240 can switch between multiple stop grooves 212, allowing the reading plate 220 to form different tilt angles relative to the support base 210, such as 15°, 30°, or 45°.

[0044] Specifically, when the tilt angle of the reading plate 220 needs to be adjusted, the support member 240 is manually lifted so that its lower end disengages from the current stop groove 212. Then, the support member 240 is rotated around its upper rotation axis to the stop groove 212 position corresponding to the target angle, and finally, the lower end of the support member 240 is inserted into the groove. The cooperation between the support member 240 and the stop groove 212 forms a rigid support, preventing the reading plate 220 from shifting its angle due to external forces during use. This embodiment, by providing multiple stop grooves 212 on the support base 210, allows the reading plate 220 to be quickly, accurately, and stably fixed at different tilt angles to adapt to different usage scenarios, effectively preventing accidental angle changes, improving the stability of the bracket, and simplifying the adjustment process.

[0045] In one embodiment, such as Figures 4 to 10 As shown, the reading bracket 200 also includes a connecting plate 250, fasteners (not shown), and mating parts (not shown). The connecting plate 250 is fixedly connected to the back of the reading plate 220, and the bottom end of the connecting plate 250 is rotatably connected to the support base 210. The mating parts are positioned and embedded in the support base 210 and / or the connecting plate 250 around the rotation axis of the support base 210. The fasteners pass through the support base 210 and the connecting plate 250 along the rotation axis and are threadedly connected to the mating parts to adjust the rotational resistance of the support base 210 and the connecting plate 250.

[0046] In this embodiment, the connecting plate 250 can be fixedly connected to the back of the reading plate 220 by means of screws, adhesive, etc. Generally, the area of ​​the connecting plate 250 is smaller than that of the reading plate 220 to reduce the overall weight and cost of the reading stand 200. It is understood that the reading plate 220 is used to hold books, and the connecting plate 250 mainly serves a connecting function; therefore, the reading plate 220 and the connecting plate 250 can be made of different materials. For example, the reading plate 220 can be made of wood to improve product quality, while the connecting plate 250 can be made of plastic to reduce cost and weight. The connecting plate 250 and the support base 210 can rotate through a lug, a pivot, etc. The fastener can be a bolt, and the mating part can be a nut. By circumferentially limiting the mating part at the end of the support base 210 or the connecting plate 250, the mating part cannot rotate relative to the support base 210 or the connecting plate 250. Thus, when the fastener passes through the support base 210 and the connecting plate 250 and is threadedly connected to the mating parts, the mating parts can be tightened or loosened by rotating the fastener, thereby changing the friction between the connecting plate 250 and the support base 210, thereby increasing or decreasing the rotational resistance between the support base 210 and the connecting plate 250, so that the reading plate 220 can rotate flexibly and maintain its angle stably, and the adjustment method is simple and easy to operate.

[0047] Furthermore, by setting this fastener and mating component, the rotational resistance between the connecting plate 250 and the support base 210 can be adjusted according to the usage scenario of the reading stand 200. For example, when the reading stand 200 is used on the desktop stand 100, the rotational resistance between the connecting plate 250 and the support base 210 should be adjusted to a larger value so that the reading plate 220 can rotate while being stably maintained at a preset angle by the resistance. When the reading stand 200 is used alone on the desktop, since the reading plate 220 can be supported on the support base 210 through the connecting plate 250, the rotational resistance between the connecting plate 250 and the support base 210 should be adjusted to a smaller value to facilitate flexible rotation of the reading plate 220.

[0048] Furthermore, a wrench mounting groove 251 is provided in the connecting plate 250, which is used for mounting a wrench for rotating and adjusting the fastener; the support member 240 is a support plate, which at least covers the wrench mounting groove 251.

[0049] In this embodiment, the size of the wrench recess 251 is adapted to the shape of a standard wrench tool to store the wrench and prevent it from slipping or being lost. In practice, the wrench is embedded in the wrench recess 251, and the end of the fastener has an adjustment groove, allowing the wrench to be fitted into the adjustment groove to rotate the fastener. The support plate is a plate-shaped component covering the surface of the connecting plate 250, completely concealing the wrench recess 251 and preventing the adjustment tool from being exposed, thus ensuring the cleanliness of the connecting plate 250's appearance. When it is necessary to adjust the rotational resistance between the support base 210 and the connecting plate 250, the wrench can be removed from the wrench recess 251 for use, and after adjustment, the wrench can be placed back into the wrench recess 251. This solution achieves tool and structure integration through the built-in wrench recess 251, and the support plate further conceals the tool storage space, simplifying the operation process and improving the product's aesthetics.

[0050] In one embodiment, such as Figures 4 to 10 As shown, the reading bracket 200 also includes a connecting plate 250, fasteners (not shown), and mating parts (not shown). The connecting plate 250 is fixedly connected to the back of the reading plate 220. The bottom of the connecting plate 250 is provided with a first lug group 252 at both ends and / or the middle. The first lug group 252 includes at least two lugs. The support base 210 is provided with a second lug group 213 corresponding to the first lug group 252. The second lug group 213 includes at least two lugs. The lugs of the first lug group 252 and the second lug group 213 are alternately inserted. The mating parts are limited and embedded in the support base 210 and / or the connecting plate 250 around the rotation axis of the support base 210. The fastener passes through the first lug group 252 and the second lug group 213 along the rotation axis and is threadedly connected to the mating parts to adjust the rotational resistance of the support base 210 and the connecting plate 250.

[0051] In this embodiment, the connecting plate 250 can be fixedly connected to the back of the reading plate 220 by means of screws, adhesive, or other methods. Generally, the area of ​​the connecting plate 250 is smaller than that of the reading plate 220 to reduce the overall weight and cost of the reading stand 200. It is understood that the reading plate 220 is used to hold books, while the connecting plate 250 mainly serves a connecting function. Therefore, the reading plate 220 and the connecting plate 250 can be made of different materials. For example, the reading plate 220 can be made of wood to improve product quality, while the connecting plate 250 can be made of plastic to reduce cost and weight.

[0052] The first lug group 252 and the second lug group 213 refer to multiple protruding structures respectively disposed on the connecting plate 250 and the support base 210. The number of lugs in the first lug group 252 and the second lug group 213 can be selected and designed according to actual needs, such as two, three, or four lugs in each lug group, etc., without specific limitation here. The connecting plate 250 forms a stable rotational connection structure by alternately inserting the lugs in the first lug group 252 and the second lug group 213 of the support base 210, ensuring that the reading plate 220 maintains its angle stably. During rotation, the alternately inserted lug groups are mechanically limited to prevent lateral displacement between the connecting plate 250 and the support base 210.

[0053] The fastener can be a bolt, and the mating part can be a nut. By circumferentially limiting the mating part at the end of the support base 210 or connecting plate 250, the mating part cannot rotate relative to the support base 210 or connecting plate 250. Thus, when the fastener passes through the support base 210 and connecting plate 250 and is threadedly connected to the mating part, the mating part can be tightened or loosened by rotating the fastener, thereby changing the friction between the connecting plate 250 and the support base 210, and thus increasing or decreasing the rotational resistance between the support base 210 and the connecting plate 250. When it is necessary to adjust the angle of the reading plate 220, the tightness of the threaded engagement can be changed by rotating the fastener, thereby adjusting the rotational resistance between the connecting plate 250 and the support base 210, so that the reading plate 220 can rotate flexibly and maintain its angle stably, and the adjustment method is simple and easy to operate. This solution achieves a detachable rotating connection by alternating the insertion of lugs and the engagement of threaded fasteners. It also allows for flexible adjustment of the rotational resistance according to usage requirements, avoiding the problem of the reading plate 220 shaking due to insufficient resistance or being difficult to adjust due to excessive resistance during use.

[0054] Furthermore, by setting this fastener and mating component, the rotational resistance between the connecting plate 250 and the support base 210 can be adjusted according to the usage scenario of the reading stand 200. For example, when the reading stand 200 is used on the desktop stand 100, the rotational resistance between the connecting plate 250 and the support base 210 should be adjusted to a larger value so that the reading plate 220 can rotate while being stably maintained at a preset angle by the resistance. When the reading stand 200 is used alone on the desktop, since the reading plate 220 can be supported on the support base 210 through the connecting plate 250, the rotational resistance between the connecting plate 250 and the support base 210 should be adjusted to a smaller value to facilitate flexible rotation of the reading plate 220.

[0055] In one embodiment, such as Figure 1As shown, the side guard assembly 230 includes a stop bar 231 and two clamping arms 233. The stop bar 231 is arranged laterally and fixedly connected to the bottom of the reading plate 220. The stop bar 231 has an upward-facing stop surface 232. The two clamping arms 233 are rotatably connected to the two ends of the stop bar 231.

[0056] The stop bar 231 is a strip-shaped structure horizontally fixed to the bottom of the reading board 220. It can be manufactured using injection molding. Its upward-facing stop surface 232 is used to block books, tablets, or other objects from slipping or shifting during reading. The stop bar 231 and the reading board 220 can be detachably or non-detachably fixedly connected; no specific limitation is made here. The clamping arms 233 are rotatable components installed at both ends of the stop bar 231. The shape and structure of the clamping arms 233 can refer to existing designs and are not limited here. The clamping arms 233 can clamp the left and right sides of the book by rotating at both ends of the stop bar 231 to enhance the fixing effect. The clamping range of the clamping arms 233 can be flexibly adjusted according to the book size.

[0057] In one embodiment, please refer to Figures 1 to 3 The desktop support 100 includes a tabletop 150, a base frame 160, and an adjusting member 170. The front of the tabletop 150 forms a drawing desktop 110, and the bottom surface of the base frame 160 forms a supporting base 120. The base frame 160 is rotatably connected to the back of the tabletop 150. One end of the adjusting member 170 is rotatably connected to the back of the tabletop 150, and the other end is movably embedded in the base frame 160 to adjust the tilt angle of the tabletop 150. A buffer sleeve 151 is fitted onto one edge of the tabletop 150 opposite to the reading bracket 200.

[0058] The tabletop 150 is used to place books, while the base frame 160 mainly provides support. Therefore, the tabletop 150 and the base frame 160 can be made of different materials. For example, the tabletop 150 can be made of wood to improve product quality, while the base frame 160 can be made of plastic to reduce cost and weight. The base frame 160 provides support for the desktop support 100 and can be rotatably connected to the tabletop 150 via a hinge structure such as a pivot. The adjusting component 170 refers to the angle adjustment mechanism connecting the tabletop 150 and the base frame 160, which can be an adjusting plate, adjusting rod, adjusting frame, or other structures. Specifically, the base frame 160 has multiple slots, and one end of the adjusting component 170 is hinged to the desktop back panel, while the other end is embedded in one of the multiple slots. By moving the adjusting component 170 to change the position of the multiple slots in the base frame 160, the angle between the tabletop 150 and the base frame 160 can be adjusted, thereby adjusting the tilt angle of the tabletop 150. The buffer sleeve 151 refers to the flexible material that wraps around the edge of the tabletop 150. It can be made of silicone or rubber to prevent direct contact between the user and the edge of the tabletop 150, thus avoiding discomfort. The buffer sleeve 151 is designed to fit snugly around the edge of the tabletop 150, making it easier to install, remove, and replace. Specifically, the buffer sleeve 151 extends from one end of the edge of the tabletop 150 to the other. A recessed groove is provided on the side of the buffer sleeve 151 facing the edge of the tabletop 150, and the edge of the tabletop 150 is fitted into this groove, allowing the buffer sleeve 151 to completely cover the edge of the tabletop 150 facing the user. This further improves the comfort of using the tabletop 150. In other embodiments, a buffer pad can also be adhered to the edge of the tabletop 150.
