Description

Technical Field

[0001] This utility model relates to the field of bookend technology, and in particular to a combined bookend. Background Technology

[0002] As a common desktop tool for supporting books and preventing them from tipping over, the flexibility of bookends and their space utilization directly determine the user experience. Currently, bookend products on the market still have significant functional limitations: one type is the one-piece fixed bookend, which consists of a base and fixed side panels forming a single storage unit. Its storage capacity is fixed and cannot be expanded. If more books need to be stored, separate bookends must be purchased and placed separately, which not only occupies too much desktop space, but the independent units without connecting structures are also prone to displacement due to external impacts, resulting in a messy arrangement of books.

[0003] In the existing technology, there are also modular bookends that can be spliced ​​together with multiple units. For example, the Chinese utility model patent "An Infinitely Combinable Bookend" with application number 201920448375.2 (authorization announcement number CN210353849U) achieves multi-unit splicing by interlocking the protrusions and grooves of the side panels of the bookend units, which solves the problem that traditional bookends cannot be stably extended. However, there are still limitations: First, after splicing, only a single continuous storage area is formed. It is essentially a linear superposition of multiple bookend units and does not generate additional independent storage space. Second, its splicing structure only undertakes the single function of "connection and fixation" and does not give the splicing parts a space expansion function, so it cannot achieve the efficient utilization effect of "adding storage space with each splicing".

[0004] In addition, although some modular bookends adopt an internal partition design, the partition structure relies on an integrated base plate. In essence, it is an internal division of a single storage space, rather than creating a new space through splicing. It also loses the flexibility of using a single unit independently and is difficult to adapt to diverse usage scenarios.

[0005] Therefore, how to overcome the limitations of existing modular bookends that "only add quantity without adding space" and design a modular bookend that can be used independently by a single unit and can also add independent storage space through simple splicing has become a technical need that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a combined bookend that can both enable the independent use of each bookend unit and add independent storage space through simple splicing, in view of the above-mentioned technical status.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a combined bookend, including at least two bookend units and at least one connecting plate, each bookend unit including a base plate and at least two side plates disposed opposite to each other on the base plate;

[0008] The bottom plate of the book stand unit is provided with a plug-in structure, and the side of the connecting plate is provided with a mating structure adapted to the plug-in structure. The connecting plate can be detachably connected to the plug-in structures of two adjacent book stand units through the mating structure.

[0009] After two adjacent bookend units are connected by the connecting plate, the surface of the connecting plate and the adjacent side plates of the two bookend units together enclose an additional storage space.

[0010] In order to achieve a reliable and easy-to-operate snap-fit ​​fixing method between the bookend unit and the connecting plate, and to facilitate production and assembly, preferably, the plug-in structure is a slot opened on the side of the base plate, and the mating structure is a buckle set on the side of the connecting plate and adapted to the slot.

[0011] To further enhance the stability of the interlocking fit and prevent relative movement or loosening of the connecting plate and the bookend unit in the horizontal direction, preferably, each side of the connecting plate is provided with at least one set of buckles, each set of buckles includes two buckle units spaced apart, and a trapezoidal notch is formed between the two buckle units in the same set, and a trapezoidal block adapted to the trapezoidal notch is provided in the slot on the side of the bottom plate of the bookend unit.

[0012] To ensure the bottom of the assembled bookend remains flat and to prevent tilting or wobbling due to the connecting structure, and to ensure the trapezoidal block fits properly with the trapezoidal notch for vertical positioning, preferably, the slot extends through the bottom of the bookend unit's base plate, and the vertical height of the buckle is consistent with the vertical depth of the slot; when the buckle is inserted into the slot, the bottom surface of the buckle is coplanar with the bottom surface of the bookend unit's base plate, and the trapezoidal block is embedded in the trapezoidal notch.

[0013] In order to effectively reduce product weight and save materials while ensuring the overall structural strength of the bookend, and to form a limited anti-slip area, preferably, the bottom plate of the bookend unit and / or the bottom of the connecting plate are provided with a recessed part, and the periphery of the recessed part forms a support frame for contacting the tabletop.

[0014] In order to flexibly adjust the size of the added storage space according to actual storage needs and enhance the applicability of the product, preferably, the length of the connecting plate is the same as the length of the bottom plate of the bookend unit, and the connecting plate is configured with a variety of different width specifications; when the connecting plate is connected to two adjacent bookend units, the connecting plates of different width specifications are respectively enclosed with the adjacent side plates of the two bookend units to form additional storage spaces with different volumes.

[0015] In order to enable bidirectional expansion of the bookend units in the horizontal direction and meet a wider range of storage needs, preferably, the connecting plate has the mating structure on both opposite sides, and the bookend unit base plate has the plug-in structure on both opposite sides, so that at least three bookend units can be bidirectionally spliced ​​together through the connecting plate.

[0016] To break away from the monotonous straight lines of traditional bookends, the height of the side panels is varied to create rich artistic lines on the top outline of the assembled bookend, enhancing the product's aesthetics and decorative appeal. Preferably, at least one bookend unit has two opposite side panels with different heights, and different bookend units have side panels with different heights. When the bookend units are sequentially assembled via the connecting plate, the top edges of each side panel together form a continuous oblique linear outline, arc outline, or wavy outline.

[0017] Compared with the prior art, the advantages of this utility model are as follows: by setting at least two independent bookend units and at least one connecting plate, and setting a plug-in structure on the side of the bottom plate of the bookend unit, and setting a matching mating structure on the side of the connecting plate, since the connecting plate can be detachably connected to the plug-in structure of the two adjacent bookend units through the mating structure, its plate surface will jointly enclose an additional storage space with the adjacent side plates of the two bookend units, thereby realizing the modularization of the bookend function. This allows each bookend unit to be used independently, and through simple and quick splicing operations, a new and independent classification and storage space can be quickly created while achieving a stable connection. This solves the defect that the existing combination bookends can only be linearly extended and cannot add space, greatly improving the flexibility of combination use and space utilization efficiency.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Figures 1-5 The figure shown is the preferred embodiment of this utility model.

[0025] The combined bookend in this embodiment mainly includes a bookend unit 1, a connecting plate 2, a plug-in structure 3, a mating structure 4, etc. Through the independent use of the bookend unit 1, the detachable and splicable connecting plate 2, and the ingenious design of adding storage space after splicing, it realizes that a single bookend unit 1 can flexibly adapt to small-capacity scenarios, and adds independent storage space after splicing and combining, while taking into account both personalized appearance and storage flexibility.

[0026] The structure and connection relationships of each component are as follows:

[0027] Book Stand Unit 1: Reference Figures 1 to 4 As shown, the bookend unit 1 serves as a basic storage unit. Each bookend unit 1 includes a base plate 1a and at least two side plates 1b arranged opposite each other on the base plate 1a. The base plate 1a is generally rectangular, and each of its two opposite sides is provided with a plug-in structure 3. In this embodiment, the plug-in structure 3 is specifically a slot 3a. The slot 3a penetrates the bottom of the base plate 1a along the height direction, and a trapezoidal block 3b is integrally formed inside the slot 3a. The cross-section of the trapezoidal block 3b is an isosceles trapezoid. The bottom of the base plate 1a is also provided with a recessed part 6. The recessed part 6 is an inwardly recessed area formed by the bottom of the base plate 1a being recessed upward. A raised support frame 6a is retained around the perimeter of the recessed part 6. The bottom surface of the support frame 6a is a flat surface, which is used to contact the tabletop to achieve stable support. The side plates 1b are vertically fixed on the base plate 1a. The two opposite side plates 1b of the bookend unit 1 can be set to different heights as needed, and the side plates 1 of different bookend units 1 can also be set to different heights as needed.

[0028] Connector 2: Reference Figures 1 to 4As shown, the connecting plate 2, as the core component connecting the bookend unit 1 and forming the additional storage space 5, is rectangular in shape. Its length is consistent with the length of the base plate 1a of the bookend unit 1, ensuring a neat overall structure after assembly. The connecting plate 2 is available in various widths to accommodate different volumes of additional storage space 5. Both opposite sides (two sides in the width direction) of the connecting plate 2 are provided with a mating structure 4. In this embodiment, the mating structure 4 is specifically a snap fastener 4a, which is integrally formed with the connecting plate 2. Each side has at least one set of snap fasteners 4a. In this embodiment, each side has two sets of snap fasteners 4a. The snap fastener 4a includes two snap fastener units 4a1 spaced apart. A trapezoidal notch 4b is formed between the two snap fastener units 4a1 to fit the trapezoidal block 3b. The cross-sectional shape of the trapezoidal notch 4b is perfectly matched with that of the trapezoidal block 3b. The vertical height of the snap fastener 4a is consistent with the vertical depth of the slot 3a, ensuring that after the snap fastener 4a is inserted into the slot 3a, the bottom surface of the snap fastener 4a is coplanar with the bottom surface of the base plate 1a. The bottom of the connecting plate 2 is also provided with a recessed part 6 and a support frame 6a. The structure is consistent with the recessed part 6 and the support frame 6a of the base plate 1a, which reduces the overall weight of the connecting plate 2 and the material cost without affecting the support stability.

[0029] Additional storage space 5: Reference Figure 1 and Figure 5 As shown, the additional storage space 5 is formed by the connecting plate 2 and the side plates 1b of the two adjacent bookend units 1. When the connecting plate 2 is connected to the plug-in structure 3 of the two bookend units 1 through the mating structure 4, the upper surface of the connecting plate 2 serves as the bottom support surface of the additional storage space 5, and the adjacent side plates 1b of the two bookend units 1 serve as the two side blocking surfaces of the additional storage space 5, together forming an independent "U"-shaped storage space. When the connecting plate 2 and the side plates 1b of different widths are enclosed, the volume of the additional storage space 5 is also different.

[0030] In this embodiment, reference Figure 5 As shown, when each bookend unit 1 is sequentially spliced ​​together by the connecting plate 2, the top edges of each side plate 1b together form a continuous outline. In this embodiment, it is specifically a diagonal linear outline. In practical applications, the height of the side plates 1b of different bookend units 1 can also be adjusted to form an arc-shaped outline or a wave-shaped outline, presenting rich artistic lines, thereby improving the overall aesthetics and decorativeness of the combined bookend.

[0031] In this embodiment, to adapt to different splicing quantity requirements, refer to Figure 4 and Figure 5As shown, each bookend unit 1 has a slot 3a on two opposite sides of the base plate 1a, and each connecting plate 2 has a buckle 4a on two opposite sides. When three or more bookend units 1 need to be spliced ​​together, the third bookend unit 1 can be connected to the second bookend unit 1 on the side away from the first bookend unit 1 through another connecting plate 2. That is, the slot 3a of the third bookend unit 1 cooperates with the buckle 4a on one side of the second connecting plate 2, and the buckle 4a on the other side of the second connecting plate 2 cooperates with the other slot 3a of the second bookend unit 1, so as to realize the bidirectional sequential splicing of multiple bookend units 1.

[0032] The working principle of the combined book stand in this embodiment is as follows:

[0033] 1. Independent Use and Stable Support: A single bookend unit 1 can be placed directly on a desktop. The support frame 6a at the bottom of the base plate 1a contacts the desktop to form a stable support. The base plate 1a and the two side plates 1b of the bookend unit 1 form a "U"-shaped basic storage space, which can be used directly to store books. The side plates 1b can prevent books from tipping over, which is suitable for small-capacity, scattered book storage scenarios. At the same time, the recessed part 6 of the base plate 1a can reduce the weight of the bookend unit 1, reduce material costs, and does not affect the stable support effect of the support frame 6a.

[0034] 2. Detachable splicing and bidirectional limiting: When splicing, first select the connecting plate 2 of the required width, align the buckle 4a on one side of the connecting plate 2 with the slot 3a of the base plate 1a of the first bookend unit 1, and insert it vertically until the bottom surface of the buckle 4a is coplanar with the bottom surface of the base plate 1a. At this time, the trapezoidal block 3b in the slot 3a is just embedded in the trapezoidal notch 4b of the buckle 4a. The left and right directions are limited by the characteristic of the trapezoidal structure that "fits at an angle and cannot be separated left and right". Then align the slot 3a of the second bookend unit 1 with the buckle 4a on the other side of the connecting plate 2 and repeat the insertion action to complete the splicing of two bookend units 1. If more bookend units 1 need to be spliced, three or more bookend units 1 can be spliced ​​sequentially through the bidirectional mating structure 4 of the connecting plate 2 and the bidirectional insertion structure 3 of the bookend unit 1.

[0035] 3. Additional storage and volume adjustment: After the two bookend units 1 are spliced ​​with the connecting plate 2, the upper surface of the connecting plate 2 and the adjacent side plates 1b of the two bookend units 1 enclose an additional storage space 5. This space is independent of the basic storage space of the bookend unit 1 and can be used to classify and store different types of books, overcoming the defect of existing combined bookends that are "only linearly stacked and have no additional storage space". When different widths of the connecting plate 2 are selected, the left and right spans of the additional storage space 5 will change accordingly, thereby adjusting the volume to meet the storage needs of different numbers and sizes of books.

[0036] 4. Personalized Appearance and Convenient Access: By designing that "at least one bookend unit 1 has two side panels 1b of different heights, and different bookend units 1 have side panels 1b of different heights", the top edges of each side panel 1b after splicing can form a continuous diagonal linear outline, arc outline, or wave outline, enhancing the aesthetics and personalization of the bookend's appearance; at the same time, the staggered side panels 1b also make it easy for users to quickly identify books in different areas (e.g., thick books in the high side panel 1b area and thin books in the low side panel 1b area), eliminating the need for repeated searching when taking out and putting away books, thus balancing appearance and practicality.
