Description

A foldable bookend

[0001] This application claims priority to a patent application filed with the State Intellectual Property Office of China on June 14, 2023, with application number 2023215139933 and invention name “A Foldable Bookstand”. Technical Field

[0002] The present application relates to the technical field of stationery products, and more specifically to a foldable bookend. Background Art

[0003] A book stand is an item used to support books to stand steadily. It is generally L-shaped. Using a book stand to store books can prevent the standing books from tilting, so as to prevent the books from being folded, bent or damaged. It can also classify and store different types of books. However, most of the book stands currently used have a fixed shape, which is inconvenient to carry and occupies a large storage space when idle, resulting in poor practicality. Therefore, the utility model patent with publication number: CN202567088U discloses a folding book stand, including a bottom plate, a vertical plate hinged on the bottom plate by a pin, and the pin with a limiting protrusion. A pin is provided between the vertical plate and the bottom plate, which can facilitate the folding of the book stand. The limiting protrusion is provided on the pin to ensure the stability of the book stand during use. This technical solution enables the book stand to be folded and stored by providing an axis pin, so as to save storage space when the book stand is idle. However, the book stand cannot be rotated and locked in both the use and storage states, and is still not reliable enough in actual use.

[0004] Summary of the Invention

[0005] The technical problem to be solved by the present application is to provide a foldable bookend that can be locked in rotation when rotated to the unfolded position and the stored state, thereby preventing accidental folding during use and accidental unfolding during storage. The bookend has a simple structure and high reliability.

[0006] The present application provides a foldable bookend, comprising a vertical plate and a bottom plate, wherein the vertical plate is provided with a first rotating connection portion, and the bottom plate is provided with a second rotating connection portion adapted to the first rotating connection portion, the first rotating connection portion is engaged with the second rotating connection portion so that the vertical plate and the bottom plate can be rotated to unfold and fold, the first rotating connection portion is provided with an elastic locking piece, and the second rotating connection portion is provided with a limiting groove adapted to the elastic locking piece, and the elastic locking piece is engaged with the limiting groove so that the vertical plate and the bottom plate are rotationally locked in an unfolded position or a folded position.

[0007] In this technical solution, the vertical plate and the bottom plate are rotationally connected through the first rotating connection part and the second rotating connection part, and the vertical plate and the bottom plate are unfolded and folded through relative rotation. By providing an elastic locking piece at the first rotating connection part and a limiting groove at the second rotating connection part, the vertical plate and the bottom plate are rotationally locked through the engagement of the elastic locking piece and the limiting groove, which can avoid the situation of accidental folding during use or accidental unfolding during storage, thereby improving the reliability of use. Since the elastic locking piece is elastic, when the user continues to rotate the vertical plate and the bottom plate, the elastic locking piece can be disengaged from the limiting groove through elastic deformation to achieve rotation unlocking, which is more labor-saving to use.

[0008] As an improvement, the limiting groove includes a first limiting groove and a second limiting groove distributed along the circumferential direction, and the distribution interval angle of the first limiting groove and the second limiting groove is 90 degrees. When the elastic locking piece is engaged with the first limiting groove, the vertical plate is perpendicular to the base plate and locked in the expanded position. When the elastic locking piece is engaged with the second limiting groove, the vertical plate is parallel to the base plate and locked in the folded position.

[0009] When the book stand is in the unfolded position, the user rotates the vertical plate and the bottom plate to the unfolded position, and the vertical plate is perpendicular to the bottom plate. At this time, the elastic locking member is exactly engaged with the first limiting groove, and the elastic locking member abuts against the first limiting groove, so that the vertical plate and the bottom plate remain rotationally locked, preventing the vertical plate and the bottom plate from rotating and folding during use. When the book stand needs to be stored, the user applies force to the vertical plate or the bottom plate so that the elastic locking member is elastically deformed and disengaged from the first limiting groove, thereby unlocking the rotation of the vertical plate and the bottom plate, and the vertical plate and the bottom plate can be rotated relative to each other to the folded position, and the vertical plate is parallel to the bottom plate. At this time, the elastic locking member is exactly engaged with the second limiting groove, and the elastic locking member abuts against the second limiting groove, so that the vertical plate and the bottom plate remain rotationally locked, preventing the vertical plate and the bottom plate from rotating and unfolding during storage, and having higher reliability in use.

[0010] As an improvement, a first protrusion is provided at one end of the elastic locking member to match the limiting groove, and the elastic locking member engages with the limiting groove via the first protrusion. In this technical solution, by providing the first protrusion on the elastic locking member, the elastic locking member achieves rotational locking through the first protrusion and the limiting groove. The provision of the first protrusion improves the matching efficiency, and the protrusion structure is simple, making it more convenient, quick and labor-saving to use.

[0011] As an improvement, the elastic locking member is a spring structure. In this technical solution, the elastic locking member is set as a spring structure with a protrusion at the end. During the rotation process, the spring structure can use elastic force to make the first protrusion enter or leave the limit groove. The structure is simple and labor-saving.

[0012] As an improvement, the second rotating connection part is provided with a rotating shaft, and the second rotating connection part is rotatably connected to the first rotating connection part via the rotating shaft. In this technical solution, the first rotating connection part and the second rotating connection part are rotatably connected via the rotating shaft, and the rotation efficiency is higher and more reliable.

[0013] As an improvement, the first rotating connection is provided with a buckle that is adapted to the rotating shaft. The buckle engages with the rotating shaft to enable the first rotating connection to be rotatably connected to the second rotating connection. In this technical solution, the buckle and the rotating shaft engage to prevent the first and second rotating connections from being separated. The buckle and the rotating shaft form a pin connection structure to improve rotation efficiency. At the same time, the rotating pin connection structure can provide a force to prevent the vertical board from being pushed outward by the book, making the use of the book stand more reliable.

[0014] As an improvement, a support surface is provided at the bottom of the first rotating connection portion, which is used to support the upright board in an upright position. In this technical solution, the first rotating connection portion is provided on the upright board. By providing the support surface at the bottom of the first rotating connection portion, when the book stand is in use, the upright board is perpendicular to the bottom board, and the bottom board is in contact with the surface on which the book stand is placed. The upright board is then perpendicular to the surface on which the book stand is placed, and the upright board is in contact with the surface on which the book stand is placed through the support surface. The support surface increases the bonding area between the upright board and the surface on which the book stand is placed, making the upright board more reliable and stable in upright position, preventing the book stand from tipping over, and making the book stand more reliable in use.

[0026] In order to better understand the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely descriptions of exemplary embodiments of the present application and are not intended to limit the scope of the present application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0027] In the drawings, the thickness, size and shape of objects have been slightly exaggerated for ease of explanation. The drawings are only examples and are not drawn strictly to scale.

[0028] It should also be understood that the terms “comprises,” “includes,” “has,” “includes,” and “containing,” when used in this specification, indicate the presence of the described features, integers, steps, operations, elements, and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts, and / or combinations thereof.

[0029] As shown in Figures 1 to 10, the present application discloses a foldable bookend, including a vertical plate 1 and a bottom plate 2, the vertical plate 1 is provided with a first rotating connection part 11, the bottom plate 2 is provided with a second rotating connection part 21 adapted to the first rotating connection part 11, the first rotating connection part 11 is rotatably connected to the second rotating connection part 21, the vertical plate 1 and the bottom plate 2 are rotatably connected through the first rotating connection part 11 and the second rotating connection part 21, the vertical plate 1 and the bottom plate 2 are unfolded and folded by relative rotation, the first rotating connection part 11 is provided with an elastic locking member 12, and the second rotating connection part 21 is provided with an elastic locking member 12. The elastic locking piece 12 is adapted to the limiting groove, and the vertical plate 1 and the bottom plate 2 are rotationally locked by the engagement of the elastic locking piece 12 with the limiting groove, so that the vertical plate 1 and the bottom plate 2 are rotationally locked in the unfolded position (at this time, the bookend is in use) or the folded position (at this time, the bookend is in storage), which can avoid the situation of accidental folding during use or accidental unfolding during storage, thereby improving the reliability of use. Since the elastic locking piece 12 is elastic, when the user continues to rotate the vertical plate 1 and the bottom plate 2, the elastic locking piece 12 can be disengaged from the limiting groove through elastic deformation to achieve rotational unlocking, which is more labor-saving to use.

[0030] As shown in Figure 4, the limiting grooves include at least two types, namely the first limiting groove 22 and the second limiting groove 23. The first limiting groove 22 and the second limiting groove 23 are distributed along the circumference of the second rotating connection part 21, and the distribution interval angle of the first limiting groove 22 and the second limiting groove 23 is 90 degrees. When the elastic locking piece 12 is engaged with the first limiting groove 22, the vertical plate 1 is perpendicular to the bottom plate 2 and locked in the expanded position. When the elastic locking piece 12 is engaged with the second limiting groove 23, the vertical plate 1 is parallel to the bottom plate 2 and locked in the folded position.

[0031] When the book stand needs to be used, as shown in Figures 5 and 6, the user rotates the vertical plate 1 and the bottom plate 2 to the unfolded position, and the vertical plate 1 is perpendicular to the bottom plate 2. At this time, the elastic locking member 12 is just engaged with the first limiting groove 22. The elastic locking member 12 abuts against the first limiting groove 22 to keep the vertical plate 1 and the bottom plate 2 locked in rotation (that is, it can prevent the vertical plate 1 and the bottom plate 2 from rotating and folding during use). When the book stand needs to be stored, as shown in Figures 9 and 10, the user applies force The elastic locking piece 12 is subjected to force on the vertical plate 1 or the bottom plate 2 to elastically deform and disengage from the first limiting groove 22, so that the vertical plate 1 and the bottom plate 2 are rotated and unlocked, and the vertical plate 1 and the bottom plate 2 can be rotated relative to each other to the folded position. The vertical plate 1 is parallel to the bottom plate 2. At this time, the elastic locking piece 12 is just engaged with the second limiting groove 23. The elastic locking piece 12 abuts against the second limiting groove 23, so that the vertical plate 1 and the bottom plate 2 remain rotationally locked, preventing the vertical plate 1 and the bottom plate 2 from rotating and unfolding when stored, and having higher reliability in use.

[0032] More specifically, as shown in Figure 3, one end of the elastic locking piece 12 is provided with a first protrusion 121 that is adapted to the limiting groove. The elastic locking piece 12 is engaged with the limiting groove through the first protrusion 121. By providing the first protrusion 121 on the elastic locking piece 12, the elastic locking piece 12 is rotated and locked by cooperating with the limiting groove through the first protrusion 121. The coordination efficiency is improved by providing the first protrusion 121, and the protrusion structure is simple, which is more convenient, quick and labor-saving to use. The elastic locking piece 12 is a spring sheet structure with a protrusion on the end. During the rotation process, the spring sheet structure can make the first protrusion 121 enter or exit the limiting groove through the elastic force. The structure is simple and labor-saving to use.

[0033] More specifically, as shown in Figures 3, 4 and 8, the second rotating connection part 21 is provided with a rotating shaft 211, and the second rotating connection part 21 is rotatably connected to the first rotating connection part 11 through the rotating shaft 211; the first rotating connection part 11 is provided with a buckle 111 adapted to the rotating shaft 211, and the buckle 111 is engaged with the rotating shaft 211 so that the first rotating connection part 11 and the second rotating connection part 21 are rotatably connected, and the buckle 111 is engaged with the rotating shaft 211 to prevent the first rotating connection part 11 from being disengaged from the second rotating connection part 21; a pin connection structure is formed by the buckle 111 and the rotating shaft 211 to improve the rotation efficiency. At the same time, the pin connection structure can provide a force to prevent the vertical board 1 from being pushed outward by the book, making the book stand more reliable.

[0034] More specifically, as shown in Figure 3, the buckle 111 is a U-shaped groove structure on the first rotating connecting part 11, and two second protrusions 112 distributed up and down are provided in the buckle 111. The rotating shaft 211 is inserted into the buckle 111, and the buckle 111 limits the rotating shaft 211 through the second protrusion 112 to prevent the rotating shaft 211 from detaching from the buckle 111. The structure is simple and the installation is labor-saving.

[0035] As an improvement, as shown in Figures 3, 7 and 8, a supporting surface 13 is provided at the bottom of the first rotating connection part 11. The supporting surface 13 is used to support the upright board 1 to stand upright. When the book stand is in use, the upright board 1 is perpendicular to the bottom plate 2, and the bottom plate 2 is in contact with the surface where the book stand is placed. The upright board 1 is perpendicular to the surface where the book stand is placed, and the upright board 1 is in contact with the surface where the book stand is placed through the supporting surface 13. The supporting surface 13 increases the bonding area between the upright board 1 and the surface where the book stand is placed, so that the upright board 1 stands more reliably and stably, prevents the book stand from tipping over, and makes the book stand more reliable to use.

[0036] This application is not limited to the above-mentioned optimal implementation method. Anyone can derive various other forms of products based on the inspiration of this application. However, no matter what changes are made in their shape or structure, any technical solution that is the same or similar to that of this application falls within the scope of protection of this application.
