Description

Bookshelf with posture reminder Technical Field

[0001] This utility model relates to the field of bookshelf technology, specifically to a bookshelf with posture reminders that can be installed on a table. Background Technology

[0002] Currently, myopia is becoming increasingly common among students, with more and more students developing myopia as they progress through higher grades. The majority of these cases are due to incorrect posture while writing and reading, specifically prolonged periods of looking down and bending over. However, the root cause is that books are placed flat on the desk, forcing students to bend over to read, leading to incorrect posture.

[0003] Meanwhile, the limited size of classroom desks makes it difficult to fit students' books and notebooks on the desktop. Some existing bookshelves allow books to be placed at an angle to prevent students from looking down while reading. However, these bookshelves, placed on top of the desks, further reduce the usable area of ​​the desktops, and their storage requires drawer space, necessitating further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a bookshelf that increases desktop space and provides posture reminders.

[0005] The purpose of this utility model is achieved as follows.

[0006] The bookshelf with posture reminder includes a fixed base, a back panel, and a support arm. The front end of the fixed base has a slot for accommodating the edge of the desktop. The top of the fixed base is higher than the top surface of the desktop. The rear end of the top of the fixed base is rotatably connected to the back panel. The rear end of the bottom of the fixed base has an abutment. One end of the support arm is rotatably connected to the back of the back panel, and the other end of the support arm abuts against the abutment. The back panel is tilted backward from bottom to top. When the support arm disengages from the abutment, the back panel flips backward. The front end of the top of the fixed base has an ultrasonic distance sensor, and the front end of the bottom of the fixed base has a magnet.

[0007] The mounting base of this utility model is installed on the edge of the desktop, and the support arm supports the back panel, so that the mounting base and the back panel form a bookshelf for tilting books, without significantly reducing the original desktop area. In general, it increases the desktop space, avoids users looking down to read books, and the back panel can be flipped for storage, making it more convenient to use. An ultrasonic distance sensor detects the sitting posture, thereby reminding the user to maintain the correct sitting posture. Magnets facilitate the installation or removal of the mounting base and the table, making it easy to upgrade existing tables.

[0008] Furthermore, the top surface of the fixing base is provided with a fixing groove that slopes backward from bottom to top, and the fixing base extends from both ends of the fixing groove.

[0009] The fixing groove secures the bottom of the tilted book, preventing it from slipping off.

[0010] Furthermore, the top rear end face of the fixing seat is provided with a first hinge, and the bottom back of the back plate is connected and fixed to the first hinge. The back plate forms the rotatable connection through the first hinge and the fixing seat. The back plate flips backward to abut against the abutment part or hangs down naturally.

[0011] The mounting base and back plate are connected by a hinge, which is simple in structure, easy to use, stable and reliable in operation, and easy to maintain and repair later.

[0012] Furthermore, a second hinge is provided on the back of the back plate, and the top front end face of the support arm is connected and fixed to the second hinge. The support arm forms the rotatable connection through the second hinge and the back plate.

[0013] The back panel and support arm are connected by a hinge, which is simple in structure, easy to use, stable and reliable in operation, and easy to maintain and repair later.

[0014] Furthermore, the back panel has a perforated section, and the support arm can rotate into the perforated section.

[0015] When folded, the support arm is hidden in the back panel, reducing space usage.

[0016] Furthermore, the front end of the fixing seat is recessed to form the slot, and the fixing seat extends from both ends of the slot. The top surface of the slot is provided with a clearance groove, and the top surface of the slot is used to contact the top surface of the desktop board.

[0017] The clearance groove reduces the contact area between the top surface of the slot and the desktop, preventing the mounting bracket from being installed unevenly.

[0018] Furthermore, a vertical mounting part extends downward from the bottom front end of the fixing base, and a mounting groove is provided on the front end face of the mounting part, with the magnet disposed in the mounting groove.

[0019] The magnets allow for easy contact with the table body beneath the desktop, thus magnetically securing the mounting base and the table body together.

[0020] Furthermore, the bottom of the fixing seat and the mounting part are L-shaped, and the front end of the bottom of the fixing seat protrudes beyond the front end of the top of the fixing seat.

[0021] The protruding mounting section facilitates contact with the table body below the desktop.

[0022] Furthermore, the back of the fixing seat is provided with a positioning groove or a positioning protrusion, which constitutes the abutment part, and the top surface of the rear end of the positioning protrusion is provided with an anti-detachment protrusion.

[0023] The abutment part supports the support arm to support the back panel when it is placed at an angle.

[0024] Furthermore, it also includes a control box and a voice module. The control box contains a power supply circuit and a programmable controller. The ultrasonic distance sensor, power supply circuit, voice module and programmable controller are electrically connected. The programmable controller presets the detection distance of the ultrasonic distance sensor. When the ultrasonic distance sensor detects that the distance to the head is less than the preset distance, the ultrasonic distance sensor sends a signal to the programmable controller, and the programmable controller controls the voice module to emit a prompt sound.

[0025] The ultrasonic distance sensor and voice module work together to provide users with timely and effective advice on adjusting their sitting posture.

[0026] This utility model features a mounting base installed on the edge of a desktop, with a support arm supporting the back panel. This creates a bookshelf for tilted book placement without significantly reducing the original desktop's usable area. Overall, it increases desktop space, prevents users from looking down while reading, and the back panel can be flipped for easy storage. An ultrasonic distance sensor detects posture, reminding users to maintain correct posture. Magnets facilitate the installation and removal of the mounting base and table, making it easy to upgrade existing desks. A fixing groove secures the bottom of tilted books, preventing them from slipping. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1, as shown in Figures 1-6, is a bookshelf with posture reminders, including a fixed base 1, a back panel 2, a support arm 3, a magnet 40, a first loose-leaf 4, and a second loose-leaf 5.

[0035] The front end of the fixing seat 1 is recessed to form the slot 10, and the fixing seat 1 extends from both ends of the slot 10. The top surface of the slot 10 is provided with a clearance groove 11. In this embodiment, the area above the slot 10 corresponding to the fixing seat 1 is the top of the fixing seat 1, and the area below the slot 10 corresponding to the fixing seat 1 is the bottom of the fixing seat 1.

[0036] One end of the first hinge 4 is fixed to the top rear end face of the fixing base 1, and the other end of the first hinge 4 is connected and fixed to the bottom back side of the back plate 2. The back side of the back plate 2 is connected and fixed to one end of the second hinge 5, and the top front end face of the support arm 3 is connected and fixed to the second hinge 5. The support arm 3 forms the rotatable connection with the back plate 2 through the second hinge 5. Preferably, the back plate 2 is provided with a hollow part 21, and the support arm 3 can rotate into the hollow part 21. The first hinge 4 and the second hinge 5 are both prior art, and their specific structures will not be described in detail here.

[0037] A vertical mounting portion 12 extends downward from the bottom front end of the fixing base 1. The front end face of the mounting portion 12 is provided with a mounting groove 13, and the magnet 40 is disposed in the mounting groove 13. Preferably, the bottom of the fixing base 1 and the mounting portion 12 are L-shaped, and the bottom front end of the fixing base 1 protrudes beyond the top front end of the fixing base 1.

[0038] In this embodiment, a positioning protrusion 61 is provided at the rear end of the bottom of the fixing base 1, and an anti-detachment protrusion 62 is provided on the top surface of the rear end of the positioning protrusion 61. The positioning protrusion 61 constitutes the abutment part 6. Of course, at least one positioning groove can also be provided on the back of the fixing base 1 along the height direction. The positioning groove constitutes the abutment part 6, that is, the bottom of the support arm 3 is inserted into the positioning groove for limitation.

[0039] The top surface of the fixing base 1 is provided with a fixing groove 14 that slopes backward from bottom to top, and the fixing groove 14 extends into the fixing base 1 at both ends. The front end of the top of the fixing base 1 is provided with a support seat 15.

[0040] During installation, align the slot 10 of the mounting base 1 with the front edge of the desktop panel (not shown in the figure), so that the protruding edge of the desktop panel is inserted into the slot 10, with the top surface of the slot 10 resting on the desktop panel. Adjust the depth of insertion of the desktop panel into the slot 10 until the mounting part 12 and the table body below the desktop panel are in contact. Generally, the table body (i.e., the back of the drawer) of a school desk is made of iron, so it can be magnetically fixed to the table body using magnet 40. If the table body is made of wood, magnet 40 or an iron plate needs to be installed on the table body to meet the requirements for magnetic fixation of the bookshelf. The mounting base 1 hooks the desktop panel through the slot 10 and is magnetically fixed with the mounting part 12. The bookshelf is securely installed and very easy and simple to assemble and disassemble, suitable for student use. To enhance the magnetic force, magnet 40 is a strong magnet.

[0041] In use, the back panel 2 flips upwards at the top, the support arm 3 rotates, and the bottom of the support arm 3 sits on the positioning protrusion 61. The positioning protrusion 61 supports the back panel 2 through the support arm 3, causing the back panel 2 to tilt backwards from bottom to top. At this time, books can be placed on the back panel 2, and the bottom of the books is limited by the fixing groove 14, making it difficult for the books to slip off.

[0042] In the folded state, when the support arm 3 disengages from the abutment part 6, the back panel 2 flips backward until it abuts against the abutment part 6. Alternatively, a clearance structure can be incorporated between the abutment part 6 and the back panel 2; for example, if the width of the abutment part 6 is smaller than the width of the openwork part 21, the back panel 2 will not contact the abutment part 6 when flipped, and will hang down naturally. The bookshelf is simple and easy to fold, requiring no disassembly and occupying drawer space.

[0043] The front end of the fixing base 1 is provided with a slot 10 for accommodating the edge of the desktop. The top of the fixing base 1 is higher than the top surface of the desktop. The rear end of the top of the fixing base 1 is rotatably connected to the back plate 2. The rear end of the fixing base 1 is provided with an abutment part 6. One end of the support arm 3 is rotatably connected to the back of the back plate 2. The other end of the support arm 3 abuts against the abutment part 6. The back plate 2 is placed at an angle from bottom to top and backward. The front end of the bottom of the fixing base 1 is provided with a magnet 40.

[0044] This embodiment also includes an ultrasonic distance sensor 7, a control box 8, and a voice module 9. The ultrasonic distance sensor 7 is mounted on the support 15 (i.e., fixed to the top front end of the mounting base 1). Both the reflecting and receiving ends of the ultrasonic distance sensor 7 are positioned towards the user, specifically tilted upwards, i.e., towards the user's head. The control box 8 and the voice module 9 are mounted on one side of the mounting base. The control box 8 contains a power supply circuit 81 and a programmable controller 82. The ultrasonic distance sensor 7, power supply circuit 81, voice module 9, and programmable controller 82 are electrically connected. The programmable controller 82 presets the detection distance of the ultrasonic distance sensor 7. The programmable controller 82 inputs a pre-recorded reminder voice. The power supply circuit 81 is generally powered by a rechargeable battery. The ultrasonic distance sensor 7, programmable controller 82, power supply circuit 81, and voice module 9 are all commercially available.

[0045] When the ultrasonic distance sensor 7 detects that the distance to the head is less than a preset distance, i.e., the user lowers their head and causes it to approach the desktop, the ultrasonic distance sensor 7 sends a signal to the programmable controller 82. The programmable controller 82 then controls the voice module 9 to emit a prompt tone. If the posture is correct, the voice module 9 remains silent to avoid affecting learning.
