Description

Technical Field

[0001] This invention relates to the field of stationery, and in particular to a simplified reading rack for holding books and other reading materials. Background Technology

[0002] Books are the primary learning materials for people. When reading, placing the book flat on the table creates a large angle between the book's surface and the viewer's line of sight, which can easily cause eye fatigue. Additionally, if the book is not held down by the sides while reading or doing homework, it tends to close automatically due to its own elasticity. If the book is held upright, both hands need to be used to hold it, which can lead to hand fatigue over time. These are some of the disadvantages of reading. Summary of the Invention

[0003] The purpose of this invention is to provide a simplified reading stand that can accommodate books of different sizes. The books can be tilted with an adjustable tilt angle. When the book is opened, it can hold the pages on both sides without the pages snapping together, which can relieve reading fatigue, facilitate reading, and has a simple structure.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this invention is as follows: a simplified reading shelf, comprising a panel, the front of which is provided with an upper left rotating plate, an upper right rotating plate, a lower left rotating plate, a lower right rotating plate, a left sliding plate, and a right sliding plate; the back of the panel is provided with a support structure; one end of the upper left and upper right rotating plates is rotatably connected to the upper left and upper right corners of the panel, respectively; the lower ends of the lower left and lower right rotating plates are rotatably connected to the lower left and lower right corners of the panel, respectively; the left sliding plate and the right sliding plate are arranged parallel to each other on the panel, located at the upper left and upper right corners of the panel. Below the rotating plate, the front of the panel is provided with grooves corresponding to the left and right sliding plates. The left and right sliding plates can slide left and right in the grooves. Each of the left and right sliding plates has a stopper on its outer side. The support structure includes an upper support rod, a lower support rod, and a pull rod. The upper ends of the upper and lower support rods are rotatably connected to the back of the panel and fixed by studs and knobs. The lower end of the lower support rod is provided with a pull rod. The upper support rod is provided with a track corresponding to the pull rod. One end of the pull rod is rotatably connected to the lower end of the lower support rod, and the other end passes through the track and is provided with a limit block.

[0005] Preferably, the lower end of the front of the panel is provided with a left book support point, a middle book support point and a right book support point in sequence. The left book support point is located at the lower left corner of the panel, the middle book support point is located at the center of the lower end of the panel, and the right book support point is located at the lower right corner of the panel.

[0006] Preferably, the upper left rotating plate and the upper right rotating plate have one end as the axis of rotation, and the rotatable angle range is 0 to 135°.

[0007] Preferably, the lower left and lower right rotating plates have their lower ends as rotation axes, and the rotatable angle range is 0 to 80°.

[0008] Preferably, the tripod is rotatably connected to the left and right sliding plates via a shaft, and a spring is provided at the shaft.

[0009] Preferably, a damping circular washer is provided at the connection between the upper end of the lower support rod and the back of the panel.

[0010] Preferably, a left spring plate is provided on the panel at the left book support point, and a right spring plate is provided on the panel at the right book support point. The left and right spring plates are rotatably connected to the panel via a shaft.

[0011] Preferably, the lower end of the front panel is provided with a book support plate extending from the lower left corner to the lower right corner of the panel. The left side of the book support plate is provided with a left book support rod, and the right side of the book support plate is provided with a right book support rod. The left and right book support rods are L-shaped structures and are rotatably connected to the panel.

[0012] Furthermore, damping rings are provided on both the left and right book support rods.

[0013] Furthermore, the panel is also provided with a U-shaped spine groove in the middle, extending from the top of the panel to the middle book support point or book support plate.

[0014] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0015] The simplified reading stand of this invention has a rotatable shaft connecting the upper left and upper right rotating plates to the panel, and a rotatable shaft connecting the lower left and lower right rotating plates to the panel. When placing books, simply rotating the upper left and upper right rotating plates and the lower left and lower right rotating plates outwards greatly increases the support area for the pages. At the same time, moving the left and right sliding plates to the left and right sides, when they are moved to the outermost position, is limited by a small screw at the back to prevent the left and right sliding plates from falling off. One end of the two clamps on the inner side relies on spring force to press the left and right pages onto the left and right sliding plates, preventing the pages from automatically snapping inwards. The support structure includes an upper support rod, a lower support rod, and a pull rod. The upper ends of the upper and lower support rods are rotatably connected to the back of the panel and are fixed by studs and knobs. Opening the support structure can support the panel and adjust the tilt of the panel, improving the flexibility of the panel's use. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1:

[0029] See from the front. Figure 1As shown, a simplified reading shelf includes a panel 1. The front of the panel has a left-upper rotating plate 2, a right-upper rotating plate 3, a left-lower rotating plate 4, a right-lower rotating plate 5, a left sliding plate 6, and a right sliding plate 7. The panel dimensions are 210×200mm. One end of the left-upper rotating plate 2 and the right-upper rotating plate 3 are rotatably connected to the upper left and upper right corners of the panel 1, respectively, with one end serving as the rotation axis, allowing for a rotation angle range of 0–135°. The lower ends of the left-lower rotating plate 4 and the right-lower rotating plate 5 are rotatably connected to the lower left and lower right corners of the panel 1, respectively, with the lower end serving as the rotation axis, allowing for a rotation angle range of 0–80°. The left sliding plate 6 and the right sliding plate 7 are parallel to each other on the upper side of the panel 1, located below the left-upper rotating plate 2 and the right-upper rotating plate 3. The front of the panel 1 has corresponding grooves for the left sliding plate 6 and the right sliding plate 7. The left and right slide plates 6 and 7 can slide left and right within the groove. Each of the left and right slide plates 6 and 7 has a retainer 8 on its outer side. The retainer 8 is rotatably connected to the left and right slide plates 6 and 7. A spring 28 is provided at the pivot. When placing books, simply rotate the upper left and upper right slide plates 3, as well as the lower left and lower right slide plates 4 and 5 outwards to open them. This greatly increases the support area on the front of the panel. At the same time, the left and right slide plates 6 and 7 can be moved to the left and right sides. When they are moved to the outermost position, they are stopped by the small screw 27 at the back to prevent them from detaching from the panel 1. The inner side of the two retainers 8 is held in place by the elastic force of the spring 28, pressing the left and right pages onto the left and right slide plates 6 and 7. The sides of the book can be fully opened and the pages cannot be automatically closed inwards. The left and right slide plates 6 and 7 can move left and right, so books of various sizes can be held by the retainers, making them more versatile.

[0030] In addition, to ensure good support for the bottom of the book when placed on the reading shelf, a central book support point 9 is provided at the bottom center of the front of panel 1, a left book support point 16 at the bottom left corner of panel 1, and a right book support point 17 at the bottom right corner of panel 1, providing more support points for the opened book and supporting the bottom of the book. A U-shaped spine groove 20 is also provided in the middle of panel 1, running from the top of panel 1 to the central book support point 9, which can accommodate the spine of the book pages, making the pages on both sides of the book flatter when opened and easier to read.

[0031] See from the back. Figure 2 and 3As shown, a support structure is also provided on the back of panel 1. The support structure includes an upper support rod 10, a lower support rod 11, and a pull rod. The upper ends of the upper support rod 10 and the lower support rod 11 are rotatably connected to the back of panel 1 and fixed by studs 23. A knob 12 is provided on the stud 23. After the knob 12 is tightened, in order to allow panel 1 to stay at any tilt angle, a damping round washer 24 is provided at the connection between the upper end of the lower support rod 11 and panel 1 to play a role in anti-slip positioning. The lower end of the lower support rod 11 is connected to the pull rod 1. 3 is a rotatable shaft connection. The upper support rod 10 is provided with a track 14 corresponding to the pull rod 13. When folded, the upper support rod 10, the lower support rod 11, and the pull rod 13 are fastened together in parallel. When opened, since one end of the pull rod 13 is rotatably connected to the lower end of the lower support rod 11, the other end can slide in the track 14 of the upper support rod 10. The limiting block 15 is used to limit the opening angle of the upper support rod 10. The upper support rod 10, the lower support rod 11, and the pull rod 13 form a stable triangular structure, which makes the support more stable.

[0032] Example 2:

[0033] This embodiment is a further improvement on Embodiment 1, see [link to Embodiment 1]. Figure 7 , Figure 8 As shown, a left spring plate 18 is provided on the panel 1 at the left book support point 16, and a right spring plate 19 is provided on the panel 1 at the right book support point 17. The left spring plate 18 and the right spring plate 19 are rotatably connected to the panel 1. The left spring plate 18 and the right spring plate 19 can press down the bottom edge of the left and right pages to prevent the left and right pages from automatically snapping together.

[0034] This embodiment is a further improvement on Embodiment 1, see [link to Embodiment 1]. Figure 9 , Figure 10 As shown, a book support plate 26, extending from the lower left corner to the lower right corner, is provided at the lower end of the front of panel 1. A left book support rod 21 is located on the left side of the support plate 26, and a right book support rod 22 is located on the right side. The left and right book support rods 21 and 22 are L-shaped and rotatably connected to panel 1. The left and right book support rods 21 and 22 not only support the bottom of the pages on both sides but also secure the bottom of the pages, preventing them from automatically snapping together. Damping rings 25 are also provided on the left and right book support rods 21 and 22 for positioning and anti-slip purposes.

[0035] See Figure 4 , 5As shown in 6, 8 and 9, it is worth mentioning that in the above embodiments, the upper left rotating plate 2, upper right rotating plate 3, lower left rotating plate 4, lower right rotating plate 5, left sliding plate 6, right sliding plate 7, left spring 18, right spring 19, left support plate 21, right support plate 22 and the support structure (upper support rod 10, lower support rod 11, pull rod 13) in the simplified reading rack can all be folded together with the panel 1 by rotating and sliding the axis to form an integrated structure for easy carrying.
