Description

Technical Field

[0001] This utility model relates to the field of folding honeycomb paper furniture technology, specifically, a folding slanted bookshelf. Background Technology

[0002] In related technologies, bookshelves have support plates or recesses on their front or back to hold books and other items. In most cases, multiple identical books are typically stacked within the same shelf area to accommodate a greater variety of books within a given display space. While this method can hold more types of books and more of the same type, it often fails to accurately and intuitively reflect changes in the quantity of each book, causing some inconvenience in book management. Utility Model Content

[0003] The purpose of this invention is to design a folding sloping bookshelf to solve the problem of troublesome book management.

[0004] This utility model is achieved through the following technical solution:

[0005] A folding inclined bookshelf includes a folded honeycomb paper core and a insert plate. The folded honeycomb paper core includes a supporting inclined surface located in the width direction of the folded honeycomb paper core. The supporting inclined surface is used to support books obliquely upward. The supporting inclined surface is provided with a slot extending along the length direction of the folded honeycomb paper core. The folded honeycomb paper core can be stretched or folded along its length direction to adjust the length of the supporting inclined surface and the slot. The insert plate includes an insertion portion and a stop portion extending upward along one side of the insertion portion. The thickness of the insertion portion matches the slot width. The insertion portion can be removably inserted into the slot. The insertion depth of the insertion portion into the slot can be adjusted to adjust the distance between the stop portion and the folded honeycomb paper core.

[0006] When the above-described structure is adopted, since the insertion plate and the slot on the supporting slope of the folded honeycomb paper core are detachably connected, and the insertion plate can control the depth of the insertion part into the slot, the extent to which the insertion part extends out of the slot determines the maximum number or thickness of books that can be placed on the insertion part. Simultaneously, the insertion plate also has an upwardly extending stop along the edge of the insertion part. This stop constrains the bottom of the book, confining it within the receiving groove formed between the supporting slope, the top surface of the insertion part, and the stop. Therefore, as the insertion part continues to be inserted into the slot, the stop pushes the bottom of the book closer to the supporting slope until the bottom of the book rests against it. This not only allows for a neat and aesthetically pleasing arrangement of books against the supporting slope by adjusting the insertion depth of the insertion plate, but also allows for adjustment of the groove width to match the book thickness, visually reflecting changes in the number of books. All of this facilitates book management for librarians to a certain extent.

[0007] To further improve the realization of this utility model, the following structure is specifically adopted: the slot extends obliquely downward from its opening into the folded honeycomb paper core to the bottom of the slot.

[0008] When the above-mentioned structure is adopted, the slot extends downward from the slot opening, which can reduce the angle between the insertion part of the insert plate and the support slope, and can better match the inclined support slope, so that the books can be placed more stably.

[0009] To further improve the realization of this utility model, the following structure is specifically adopted: the groove depth direction of the slot is perpendicular to the support slope.

[0010] To further improve the present invention, the following structure is adopted: the stop portion is perpendicular to the insertion portion or forms an acute angle with the insertion portion.

[0011] To further improve the present invention, the following structure is specifically adopted: when the plug is inserted into the slot and abuts against the bottom of the slot, the stop part is in contact with or spaced from the support slope.

[0012] Alternatively, when the plug is inserted into the slot and the stop contacts the support slope, the plug is spaced apart from the bottom of the slot.

[0013] To further improve the realization of this utility model, the following structure is specifically adopted: the supporting inclined surface is provided with multiple slots arranged side by side, and the length of a single slot is equal to or less than the length of the folded honeycomb paper core;

[0014] Alternatively, the supporting inclined surface may be provided with a slot, the length of which is equal to or less than the length of the folded honeycomb paper core.

[0015] To further improve the realization of this utility model, the following structure is specifically adopted: when the single slot is in a stretched state, at least two insert plates can be inserted side by side at the same time.

[0016] When the above-mentioned structure is adopted, at least two insert plates can be placed side by side in the slot, which can better separate different books. By adjusting the insertion depth of the insert plate, different books can be managed separately, and the quantity of different books can be reflected more clearly and intuitively.

[0017] To further improve the present invention, the following structure is adopted: both ends of the folded honeycomb paper core are fixed with end plates, and the end plates cover the end faces of the folded honeycomb paper core.

[0018] To further improve the realization of this utility model, the following structure is specifically adopted: the folded honeycomb paper core has two opposing support slopes in the width direction, and the support slopes are provided with at least one of the slots.

[0019] To further improve the realization of this utility model, the following structure is specifically adopted: the folded honeycomb paper core includes a base and a display platform disposed on the top of the base, and the supporting inclined surface is disposed on the display platform; the width of the base is greater than the width of the display platform.

[0020] When the above-mentioned structure is adopted, the folded honeycomb paper core raises the display stand for placing books through the base, allowing the books to be placed at a more suitable height, making it easier for people to pick them up.

[0021] To further improve the realization of this utility model, the following arrangement structure is adopted: the display stand is centrally located on the top of the base in the width direction of the folded honeycomb paper core.

[0022] When the above-mentioned structure is adopted, the centrally arranged display stand can leave a considerable and more reasonable space on both sides of the display stand with two supporting slopes. At the same time, a stepped surface can be formed on the top of the base for temporary placement of personal items and books.

[0023] This utility model has the following advantages and beneficial effects:

[0024] In this invention, the insertion plate and the slot on the supporting slope of the folded honeycomb paper core are detachably connected, and the insertion plate can control the depth of the insertion part into the slot. Therefore, the extent to which the insertion part extends beyond the slot determines the maximum number or thickness of books that can be placed on the insertion part. Simultaneously, the insertion plate has an upwardly extending stop along the edge of the insertion part. This stop constrains the bottom of the book, confining it within the receiving groove formed between the supporting slope, the top surface of the insertion part, and the stop. Therefore, as the insertion part continues to be inserted into the slot, the stop pushes the bottom of the book closer to the supporting slope until the bottom of the book rests against it. This not only allows for a neat and aesthetically pleasing arrangement of books against the supporting slope by adjusting the insertion depth of the insertion plate, but also allows for adjustment of the groove width to match the book thickness, visually reflecting changes in the number of books. All of this facilitates book management for librarians to a certain extent. Attached Figure Description

[0044] Folding honeycomb paper furniture (also known as accordion paper furniture) on the market makes furniture placement very flexible. Folding honeycomb paper furniture is mainly composed of foldable honeycomb paper cores, which are made of multiple relatively soft cardboard layers glued together. Each pair of cardboard layers is glued together to form multiple honeycomb columns arranged sequentially and spaced apart along the width of the paper. These honeycomb columns extend along the length of the paper, running vertically and horizontally, giving the appearance a honeycomb textured surface and a striped textured surface. For example, the honeycomb structure disclosed in Chinese utility model patent CN211242475U is a device using a honeycomb structure material. Due to its structural characteristics, honeycomb paper can be stretched and unfolded perpendicular to the honeycomb columns when in use or folded and stored perpendicular to the honeycomb columns when not in use, making flexible use of indoor space and therefore popular with consumers. The stretched length of the honeycomb paper core is mainly determined by the number of paper pairs (i.e., the number of cardboard pairs that make up the honeycomb columns).

[0045] On the one hand, this utility model provides a folding slanted bookshelf, which makes book management more convenient, and is specifically designed with the following structure:

[0046] The basic folding slanted bookshelf 100 includes a folded honeycomb paper core 10 and matching inserts 20.

[0047] like Figure 1 and Figure 2 As shown, the folded honeycomb paper core 10 can be stretched or folded along its length to adjust its unfolding degree. The greater the unfolding degree, the longer the length, but the folded honeycomb paper core 10 itself has a maximum unfolding degree. The folded honeycomb paper core 10 is provided with a support slope 11 for supporting the book at an upward angle. The support slope 11 is located on one side or two opposite sides of the folded honeycomb paper core 10 in the width direction. Figure 1 - Figure 5 as well as Figure 8 In the structure shown, each of the folded honeycomb paper cores 10 has a supporting inclined surface 11, and Figure 7 The structure shown includes a folded honeycomb paper core 10 with two supporting ramps 11.

[0048] For example, the inclination angle of the supporting inclined surface 11 is 85°, 80°, 78°, etc.

[0049] like Figure 1 and Figure 2 As shown, a slot 12 is provided on the supporting inclined surface 11, and the slot 12 extends along the length direction of the folded honeycomb paper core 10. The length of the slot 12 can be designed as needed; for example, the length of the slot 12 can be equal to the length of the folded honeycomb paper core 10, so that the slot 12 can... Figure 1 , Figure 2 As shown, it is configured as a through slot, that is, the two ends of slot 12 are like... Figure 8 As shown, the slots 12 extend to the corresponding end faces of the folded honeycomb paper core 10. Of course, the length of the slot 12 can also be less than the length of the folded honeycomb paper core 10. In this case, at least one end of the slot 12 is no longer located on the end face of the corresponding end of the folded honeycomb paper core 10. The depth of the slot 12 is not such that the slot 12 extends from one side of the folded honeycomb paper core 10 to the other side in the width direction.

[0050] like Figure 1 and Figure 2 As shown, the folded honeycomb paper core 10 can be stretched or folded along its length to adjust its length, for example, from... Figure 1 The fully folded state shown Figure 2 The unfolded state is shown. During the process of adjusting the length of the folded honeycomb paper core 10 by stretching, the lengths of the supporting inclined surface 11 and the slot 12 are also adjusted synchronously.

[0051] like Figure 1 As shown, the insert plate 20 has been removed from the slot 12 of the folded honeycomb paper core 10. It can be seen that the insert plate 20 is roughly L-shaped, which includes an insertion part 21 and a stop part 22 fixed to one side edge of the insertion part 21 and extending upward. The insertion part 21 and the stop part 22 can be two parts of an integral structure, or they can be two parts fixedly spliced ​​or glued together.

[0052] The thickness of the plug part 21 matches the width of the slot 12, so that the plug part 21 can be easily inserted into and pulled out of the slot 12, and the plug part 21 can basically not flip downward. That is, the width of the slot 12 needs to be roughly equal to the thickness of the plug part 21, but slightly larger.

[0053] The insertion part 21 can be removably inserted into the slot 12. We can adjust the depth of the insertion part 21 into the slot 12 to simultaneously adjust the distance between the stop part 22 and the corresponding support slope 11 of the folded honeycomb paper core 10. In use, the insertion plate 20 needs to be... Figure 3 Insert the stop 22 into the slot 12 with the stop facing upwards, as shown, so that the stop 22 can restrict the bottom of the book.

[0054] Since the insert plate 20 and the slot 12 provided on the supporting inclined surface 11 of the folded honeycomb paper core 10 are detachably connected, and the insert plate 20 can control the depth of the insertion part 21 inserted into the slot 12, the extent to which the insertion part 21 extends out of the slot 12 determines the maximum number or thickness of books that can be placed on the insertion part 21. At the same time, the insert plate 20 also has an upwardly extending stop part 22 provided on the edge of the insertion part 21, so the stop part 22 can constrain the bottom of the book to restrict the book within the receiving groove 40 formed between the supporting inclined surface 11, the top surface of the insertion part 21, and the stop part 22. Therefore, as the insertion part 21 continues to be inserted into the slot 12, the stop part 22 will push the bottom of the book close to the support slope 11 until the bottom of the book is against the support slope 11. In this way, not only can the insertion degree of the insertion plate 20 be adjusted to make the book neatly and beautifully against the support slope 11, but the width of the receiving slot 40 can also be adjusted to match the thickness of the book by adjusting the insertion degree of the insertion plate 20, which can intuitively reflect the change in the number of books. All of this can facilitate the book management work of librarians to a certain extent.

[0055] If there are no more books placed on the insertion part 21 of the insert plate 20, the insert plate 20 can be removed from the slot 12, so that part of the slot 12 is open as follows: Figure 5 Leave a blank space as shown.

[0056] According to some optional embodiments, the support slope 11 presents a regular striped texture surface, and along the length direction of the folded honeycomb paper core 10, the support slope 11 presents a series of vertical stripes arranged in sequence.

[0057] In some embodiments, the main structure of the folding inclined bookshelf 100 includes an end plate 30 in addition to the folding honeycomb paper core 10. For example... Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, end plates 30 are fixedly connected to both ends of the folded honeycomb paper core 10 along its length. The shape of the end plates 30 is designed to mimic the end faces of the corresponding ends of the folded honeycomb paper core 10, completely covering the end faces of the corresponding ends of the folded honeycomb paper core 10. The end plates 30 can be made of wood, cardboard, plastic, or other materials, and their hardness and / or stiffness must be greater than that of the folded honeycomb paper core 10 to protect the ends of the folded honeycomb paper core 10 from deformation and to improve its support capacity. The end plates 30 are generally glued together after applying adhesive to them and / or the end faces of the folded honeycomb paper core 10 using a glue roller.

[0058] According to some optional embodiments, the slots 12 formed on the supporting slope 11 of the folded honeycomb paper core 10 are inclined, specifically as follows: Figure 2 and Figure 8As shown, slot 12 extends diagonally downwards from its opening into the folded honeycomb paper core 10 to the bottom of the slot, meaning the height of the bottom of the slot is lower than the height of the opening. For example... Figure 4 , Figure 5 and Figure 7 As shown, when the insert plate 20 is inserted into the slot 12, the insert plate 20 is tilted upwards. In this embodiment, from Figure 4 As can be seen, the downward-sloping extension of the slot 12 from the slot opening can reduce the angle between the insertion part 21 of the insert plate 20 and the support slope 11, which can better match the inclined support slope 11 and allow the books to be placed more stably.

[0059] For example, the angle between the groove depth direction of the slot 12 and the supporting inclined surface 11 is 95°, 93°, 90°, 89°, 88°, 87°, 85°, etc. Preferably, the groove depth direction of the slot 12 is perpendicular to the supporting inclined surface 11.

[0060] According to some alternative embodiments, in the insert plate 20, the stop portion 22 is perpendicular to the insert portion 21. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In the shown insert plate 20, the stop part 22 is the vertical insertion part 21.

[0061] According to some alternative embodiments, the angle between the stop portion 22 and the insertion portion 21 is an acute angle.

[0062] According to some optional embodiments, after the insertion portion 21 of the insert plate 20 is inserted into the slot 12, the insertion portion 21 can abut against the bottom of the slot 12. In this case, the stop portion 22 can contact the support slope 11. When the stop portion 22 of the insert plate 20 is parallel to the support slope 11 of the folded honeycomb paper core 10, the stop portion 22 can contact the support slope 11 completely and fit together; when the stop portion 22 of the insert plate 20 is not parallel to the support slope 11 of the folded honeycomb paper core 10, the top edge or bottom of the stop portion 22 can contact the support slope 11.

[0063] According to some alternative embodiments, after the insertion portion 21 of the insert plate 20 is inserted into the slot 12, the insertion portion 21 can abut against the bottom of the slot 12. In this case, the stop portion 22 is spaced apart from the support slope 11, so that a certain width of receiving groove 40 is maintained between the stop portion 22 and the support slope 11.

[0064] According to some alternative embodiments, when the insertion portion 21 of the insert plate 20 is inserted into the slot 12 of the folded honeycomb paper core 10 and the stop portion 22 contacts the support slope 11 of the folded honeycomb paper core 10, the insertion portion 21 is spaced from the bottom of the slot 12, that is, the width of the insertion portion 21 is smaller than the depth of the slot 12.

[0065] According to some alternative embodiments, at least one slot 12 may be provided on the support slope 11 of the folded honeycomb paper core 10 as needed. Figure 1 and Figure 2 The illustration shows a case where multiple slots 12 are formed on the support slope 11 of the folded honeycomb paper core 10. For a single support slope 11, these slots 12 are arranged side-by-side in a parallel manner. On a single support slope 11, the slots 12 can be... Figure 2 The two paths shown can also be Figure 5 and Figure 8 The three paths shown can, of course, be more than three.

[0066] The length of the single slot 12 is equal to or less than the length of the folded honeycomb paper core 10.

[0067] The single slot 12 provided on the supporting inclined surface 11 of the folded honeycomb paper core 10 has sufficient stretchability. Combined with a certain length of insert plate 20, when the single slot 12 is in a stretched state, such as... Figure 3 , Figure 5 and Figure 6 As shown, at least two insert plates 20 can be inserted side by side into slot 12 at the same time.

[0068] In slot 12, among at least two insert plates 20 arranged side by side, the lengths of the two insert plates 20 may be the same or different.

[0069] The single-channel slot 12 provided on the supporting inclined surface 11 of the folded honeycomb paper core 10 has sufficient stretchability. Simultaneously, it is paired with an insert plate 20 whose length matches the stretchability of the slot 12. When the single-channel slot 12 is in the stretched state, such as... Figure 3 , Figure 5 and Figure 6 As shown, a plug-in plate 20 can be inserted into slot 12.

[0070] In some embodiments, such as Figure 3 As shown, when multiple slots 12 are provided on a single support slope 11 of the folded honeycomb paper core 10, multiple insert plates 20 can be simply inserted into a single slot 12, or a single insert plate 20 of matching length can be simply inserted.

[0071] The slot 12 can accommodate at least two insert plates 20 side by side, which can better separate different books. By adjusting the insertion depth of the insert part 21 of the insert plate 20, different books can be managed separately, and the quantity of different books can be reflected more clearly and intuitively. For example, books 1 and 2 are placed on the insertion parts 21 of two insert plates 20 and supported by the supporting slope 11. Initially, five books of each type are stacked at the same time. After a period of sales, one book of book 1 and three books of book 2 have been sold. Since books 1 and 2 may not be placed tightly against the supporting slope 11, it may appear that there are still four books left in each type. If we push the insert plates 20 inward, the stop part 22 will push the bottom of books 1 and 2 closer to the supporting slope 11 until the innermost book of each type is tightly against the supporting slope 11 and all books are tightly packed together. At this point, we can clearly judge the number of books 1 and 2 remaining, providing a clear indication to the library staff, letting them know which books are selling well and what stock needs to be replenished in advance. Pushing the insert plates 20 to make the books tightly packed also makes the stacked books neater, preventing them from becoming messy after being borrowed and returned, thus reducing the daily workload of the library staff.

[0072] According to some optional embodiments, such as Figure 1-5 and Figure 8 The folded honeycomb paper core 10 shown has only one supporting slope 11.

[0073] According to some other alternative embodiments, such as Figure 7 As shown, the folded honeycomb paper core 10 of the folded inclined bookshelf 100 has two supporting inclined surfaces 11, which are located on opposite sides in the width direction of the folded honeycomb paper core 10. This folded honeycomb paper core 10, which can hold books on both sides, can display more books.

[0074] According to some other alternative embodiments, such as Figure 1-5 and Figure 8 The folded honeycomb paper core 10 shown has only one supporting slope 11.

[0075] According to some other alternative embodiments, such as Figure 7 As shown, the folded honeycomb paper core 10 used in the folded inclined bookshelf 100 is compared to... Figure 1-5 and Figure 8 The folded honeycomb paper core 10 used in the folded sloping bookshelf 100 shown includes a base 1a in addition to the display stand 1b. Specifically, the display stand 1b is located on top of the base 1a, and the supporting sloping surface 11 is located on the display stand 1b. The width of the base 1a is greater than the width of the display stand 1b, so that the transition area between the top of the base 1a and the display stand 1b can form a stepped surface 13.

[0076] In this embodiment, the folded honeycomb paper core 10 of the folded inclined bookshelf 100 raises the display stand 1b for placing books via the base 1a, which allows the books to be placed at a more suitable height for easy access.

[0077] Preferably, the display stand 1b is centrally located on top of the base 1a in the width direction of the folded honeycomb paper core 10. This central arrangement allows the display stand 1b, with its two supporting ramps 11, to provide ample and more reasonable space on both sides. It also creates a stepped surface 13 on top of the base 1a for temporarily placing personal items and retrieving books.

[0078] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
