Abstract
Description
Technical Field
[0001] This invention belongs to the field of couplet technology, specifically a couplet character block, couplets made using the block, and a storage box. Background Technology
[0002] Pasting couplets is a traditional Chinese folk custom, which has great value in promoting Chinese culture. Even with social development, many households still maintain this custom during the Spring Festival. Traditional couplets are written on paper, forming auspicious phrases. Printed paper couplets also exist, and they are pasted onto both sides of the door using glue.
[0003] However, existing paper couplets have the following problems: 1) It is made by printing on paper materials, which requires a lot of paper and pigments, and consumes a lot of wood and water resources during the processing. 2) It requires glue to stick to the door panel, which makes it inconvenient for people to change or adjust the position of the couplets later. After the old couplets are removed, there will be adhesive residue left on the posting site, which is troublesome to clean and affects the display effect of the new couplets. 3) These couplets, which are pasted on the gate, are easily soaked and faded by wind and rain. They are also prone to mold or damage after being exposed to moisture. For non-flat surfaces, the paper is also prone to tearing or holes when subjected to minor external impacts, which affects the appearance of the couplets. 4) Paper couplets used by ordinary households have almost no recycling value after use, and they are not reusable. Therefore, they are usually discarded as waste paper, which increases the work of subsequent environmental protection and has a single use value. 5) These are usually fixed-length products. Personalized products require individual customization, which is costly and lacks the flexibility to combine and assemble. Summary of the Invention
[0004] This invention provides a couplet-shaped character block, a couplet made using the block, and a storage box. The modular design of the character block gives it a certain strength and waterproof performance. The couplet modules are detachably hinged, allowing for quantity matching and flexible assembly according to the content of the couplet. Hanging and fixing are used for easy posting. After use, the character blocks can be reassembled to form a storage box, or directly or simply modified for use as other household items, achieving secondary utilization and effectively avoiding material waste, reducing resource waste and environmental pollution.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A couplet-shaped character block includes an annular outer frame, a font back plate fixedly disposed within the annular outer frame, and a font block fixedly disposed on the surface of the font back plate. Connecting protrusions and connecting grooves are arranged alternately on the four outer edges of the annular outer frame. Each connecting protrusion on the same outer edge has a shaft hole coaxially formed. Each outer edge of the same annular outer frame can be hinged to an annular outer frame. The length of the connecting protrusion is not greater than the width of the connecting groove that it is inserted into.
[0006] In another preferred embodiment, the interior of the annular outer frame is a hollow structure, and the inner wall contour matches the outer contour of the font back panel, which is detachably embedded in the hollow of the annular outer frame.
[0007] In another preferred embodiment, the interior of the annular outer frame is a hollow structure, the font backplate is suspended inside the hollow of the annular outer frame, and the edge of the font backplate is provided with an extension connecting arm, which is detachably fixed to the back of the annular outer frame.
[0008] In another preferred embodiment, the annular outer frame is formed by a first housing and a second housing being fastened together, and the edge of the font backplate is held between the first housing and the second housing.
[0009] In another preferred embodiment, the annular outer frame and the font back panel are integrally formed, or the font block and the font back panel are integrally formed, or the annular outer frame, the font back panel and the font block are integrally formed.
[0010] In another preferred embodiment, the surface of the font block is black or gold, and the surface of the font backplate is red.
[0011] In another preferred embodiment, the number of connecting protrusions and connecting grooves on each outer edge of the annular outer frame is the same, and the connecting protrusions and connecting grooves on each side are distributed in the same direction.
[0012] A couplet is also provided, including a left couplet, a right couplet, and a horizontal scroll. The left and right couplets are each made by arranging several couplet character blocks as described above vertically and then hinged together end to end in sequence. The horizontal scroll is made by arranging several couplet character blocks as described above horizontally and then hinged together in sequence.
[0013] In another preferred embodiment, the couplet character block is provided with a fixing connection hole and / or the back of the couplet character block is provided with a fixing connection block.
[0014] In another preferred embodiment, the top ends of the left and right couplets are hinged to a first connecting plate and / or the bottom ends of the left and right couplets are hinged to a second connecting plate, wherein the first connecting plate / second connecting plate is provided with a fixing connecting hole or the back of the couplet character block is provided with a fixing connecting block.
[0015] Another storage box is provided, including a base plate, four side plates respectively hinged to the four sides of the base plate, and a flip-top plate hinged to the top of one of the side plates. The vertical sides of two adjacent side plates are hinged together. The base plate, side plates and flip-top plate all adopt the couplet-shaped blocks as described above.
[0016] A storage box is provided, comprising a base plate, four side plates respectively hinged to the four edges of the base plate, and a half-flip cover hinged to the top of two opposite side plates. The vertical sides of two adjacent side plates are hinged together. The base plate and side plates are both made of the couplet characters as described above. The length of the two half-flip covers matches the width of the couplet characters, and the sum of the widths of the two half-flip covers is not greater than the width of the couplet characters.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The modular design of the couplet blocks facilitates mass production, packaging, and transportation. The couplet modules are detachably hinged, allowing for easy matching of quantities and flexible assembly based on the content of the couplets. After use, the couplet blocks can be reassembled into storage boxes, or directly or simply modified for use as other household items, achieving secondary utilization. This effectively avoids material waste, makes the most of resources, and aligns with the green, low-carbon, and circular lifestyle and green development concepts. 2. The couplet characters of this invention are made of biodegradable and environmentally friendly materials, which are harmless to the human body and the environment. Through reuse, they replace the traditional method of using paper couplets and discarding them after use. This avoids the consumption of wood and water resources in the production of paper couplets, and also avoids the pollution to the environment and urban appearance caused by the disposal of paper couplets. This is in line with the green and environmentally friendly concept of saving resources and protecting the environment. 3. The couplet characters of the present invention have certain strength and waterproof performance, and can maintain the integrity of appearance for a long time. It can effectively avoid the problems of traditional paper couplets being easily torn by external impacts during use, and easily becoming moldy or damaged after being exposed to moisture, thus improving the stability of couplets during use. 4. The couplets of this invention adopt a hanging fixing method, which is flexible and diverse, and the hanging position is easy to change. This replaces the shortcomings of traditional paper couplets, which require glue or tape to stick together and whose position is fixed and cannot be adjusted after gluing. Moreover, the vertical state can be automatically adjusted by the weight of the couplets themselves during the hanging process. The operation is simple and avoids the tedious operation of carefully smoothing the paper and carefully correcting the position of the paper during the pasting process of traditional paper couplets.

Detailed Implementation
[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.
[0021] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] See appendix Figure 1 A couplet-shaped character block includes an annular outer frame 1, a font backing plate 2 fixedly disposed within the annular outer frame 1, and font blocks 3 fixedly disposed on the surface of the font backing plate 2. The annular outer frame 1, font backing plate 2, and font blocks 3 are all made of plastic material (such as PVC, preferably biodegradable environmentally friendly materials such as PETG, PLA, etc.) through injection molding or 3D printing, or made of environmentally friendly rigid materials (such as reinforced resin board, bamboo board) through cutting, drilling, and other mechanical processing. This ensures that the couplet-shaped character block has good overall support strength, maintaining flatness during use; furthermore, it is environmentally friendly after disposal, and good degradation ability is preferred.
[0024] To conform to the characteristics of traditional self-linking and to be aesthetically pleasing, the surface (or the whole) of font block 3 is black or golden yellow, the surface (or the whole) of font back plate 2 is red (Chinese red, such as pomegranate red, jujube red, cinnabar red, etc.), and the ring-shaped outer frame 1 is the same color as font back plate 2 or is another color (such as gilding, violet, olive green, etc.).
[0025] Connecting protrusions 101 and connecting grooves 102 are alternately distributed on the four outer edges of the annular outer frame 1. Each connecting protrusion 101 on the same outer edge has a coaxial shaft hole 103. Each outer edge of the same annular outer frame 1 can be hinged to an annular outer frame 1. The length of the connecting protrusion 101 is not greater than the width of the connecting groove 102 with which it is inserted. In this way, the connecting protrusions 101 and connecting grooves 102 on the edges of two adjacent annular outer frames 1 can be sequentially interlocked and connected by a shaft inserted in the shaft hole 103. The outer end of the connecting protrusion 101 is an arc surface with a diameter matching the thickness of the annular outer frame 1. The shaft hole 103 is coaxial with the arc surface, and the vertical distance between the axis of the shaft hole 103 and the bottom surface of the connecting groove 102 matches the radius of the arc surface. Thus, after two adjacent annular outer frames 1 are hinged, the two sides on the same side can freely and quickly switch between two positions that are perpendicular to each other and located in the same plane. Furthermore, through the contact friction between the arc surface of the connecting protrusion 101 and the bottom surface of the connecting groove 102, the rotating pair can maintain its relative position unchanged without the action of obvious external force.
[0026] To facilitate the assembly and disassembly of two adjacent annular outer frames 1, preferably, the shaft is a smooth screw. The shaft hole 103 of a connecting protrusion 101 located at the center has internal thread sections at both ends that match the external thread section of the smooth screw, while the shaft holes 103 of the remaining connecting protrusions 101 are circular through holes that match the smooth portion of the smooth screw. Thus, after the connecting protrusions 101 and connecting grooves 102 on the edges of two adjacent annular outer frames 1 are sequentially interlocked, two smooth screws can be inserted through the shaft holes 103 at both ends of the hinge position and threadedly connected to the threaded holes at both ends of the connecting protrusion 101 at the center position, thereby hinged the two adjacent annular outer frames 1. Using the same hinge method, an annular outer frame 1 can be extended to any side edge as needed. More preferably, a countersunk hole is provided at the outer end of the shaft hole 103 of the outermost connecting protrusion 101 to completely embed the head of the smooth screw into the shaft hole 103, preventing it from being exposed and affecting aesthetics. Example 1:
[0027] like Figures 1 to 3As shown, in this embodiment, the annular outer frame 1 is a square frame structure with a hollow square interior. The font back plate 2 is a square thin plate structure, and its dimensions are consistent with the dimensions of the hollow structure of the annular outer frame 1, meaning that the inner wall contour of the annular outer frame 1 matches the outer contour of the font back plate 2. Thus, the font back plate 2 is detachably embedded in the hollow of the annular outer frame 1, achieving a fixed assembly through a tight fit, or by applying environmentally friendly adhesive to the connection point to enhance the assembly's strength, or by setting self-tapping screws on the side of the annular outer frame 1 and connecting them to the side of the font back plate 2, further fixing the font back plate 2 within the annular outer frame 1. The font block 3 is fixed to the surface of the font back plate 2 through detachable methods such as mortise and tenon joints (e.g., setting a groove on the surface of the font back plate 2 with the same outer contour as the font block 3), adhesive bonding (applying environmentally friendly adhesive to the bonding surface), screw connection (setting it on the back of the font back plate 2 and connecting it to the back of the font block 3), and post-hole insertion (insertion posts and insertion holes are set separately or simultaneously in groups on the bonding surface).
[0028] It adopts a detachable assembly method, which facilitates the individual batch processing of each component, as well as the universal partial replacement and free combination of different colors and shapes.
[0029] Preferably, to facilitate quick and accurate positioning of the font backplate 2 within the annular frame 1 and improve assembly efficiency, the back of the font backplate 2 is flush with the back of the annular frame 1. Simultaneously, an arc-shaped positioning block 104 is integrally provided on the inner side of each side border of the annular frame 1, and a positioning groove matching the positioning block 104 is formed on the edge of the font backplate 2. Further, to facilitate stacking and packaging of multiple couplet characters, the outer surface of the font block 3 is located inside the outer surface of the annular frame 1. At the same time, to highlight the three-dimensional effect of the font block 3 and reduce the overall weight of the couplet characters, the thickness of the font block 3 is maximized while the thickness of the font backplate 2 is minimized while ensuring sufficient strength; that is, the sum of the thickness of the font block 3 and the thickness of the font backplate 2 is not greater than the thickness of the annular frame 1. Even further, to minimize the thickness of the font backplate 2 while ensuring sufficient strength, the back of the font backplate 2 is provided with several reinforcing ribs 201 arranged in a wide range of directions.
[0030] More preferably, to meet the need for fixing the couplet characters on a vertical plane (such as the surface of a door or wall), fixing connection holes 105 are respectively provided at the four corners of the annular outer frame 1. The couplet characters can be suspended and fixed by engaging with screw suction cups (suitable for smooth surfaces), self-tapping screws (suitable for wooden surfaces), cement nails (suitable for rough wall surfaces), etc., which are fixed and horizontally arranged on the vertical plane. Alternatively, hanging holes 106 are provided separately or simultaneously with the fixing connection holes 105 in the middle of the four sides of the annular outer frame 1 (preferably the positioning block 104 is also located at this position). The couplet characters can be suspended and fixed by engaging with protrusions (such as hooks, screw suction cups, expansion screws, etc.) fixed on the vertical plane through the hanging holes 106. Alternatively, a fixing block 202 may be provided on the back of the font back plate 2, either alone or simultaneously with the fixing connection hole 105 / hanging hole 106. By fixing double-sided adhesive, a strong magnet, or a strong magnet strip on the fixing block 202, the couplet characters can be bonded to the smooth surface of the vertical plane by the double-sided adhesive to achieve suspension and fixation, and the couplet characters can be magnetically attracted to the iron-nickel material surface by the strong magnet or strong magnet strip to achieve suspension and fixation.
[0031] like Figure 1 As shown, in this embodiment, the number of connecting protrusions 101 and connecting grooves 102 on each outer edge of the annular outer frame 1 is the same, and the connecting protrusions 101 and connecting grooves 102 on each side are distributed in the same direction, that is, arranged in a clockwise order of "convex-concave-convex-concave-...-convex-concave". Thus, after four identical couplet characters are hinged end-to-end to form a rectangular frame, the connecting protrusions 101 and connecting grooves 102 on the same open side of the rectangular frame are arranged in a counter-clockwise order of "convex-concave-convex-concave-...-convex-concave". Therefore, the four edges of the fifth couplet character can perfectly fit into the four edges of the same open side to form a box structure. This structural design provides structural support for building a storage box for couplet characters. Example 2:
[0032] like Figure 4As shown, the difference between this embodiment and the previous embodiment is that the font backplate 2 is suspended inside the hollow of the annular outer frame 1, and the edge of the font backplate 2 is provided with an extension connecting arm 203, which is detachably fixedly connected to the back of the annular outer frame 1. Specifically, to ensure that there is no protruding area in the middle of the back of the couplet characters after the font backplate 2 and the annular outer frame 1 are assembled, the back of each side frame of the annular outer frame 1 is provided with a connecting slot 107 that matches the extension connecting arm 203. In this way, after each extension connecting arm 203 is correspondingly embedded in the corresponding connecting slot 107, the font backplate 2 can be positioned in the annular outer frame 1, that is, it is not necessary for the outer contour of the font backplate 2 to be consistent with the inner contour of the annular outer frame 1; by fixing the extension connecting arm 203 to the connecting slot 107 with screws, the fixed assembly of the font backplate 2 in the annular outer frame 1 can be achieved. Example 3:
[0033] like Figure 5 and Figure 6 As shown, the difference between this embodiment and the aforementioned embodiments lies in that: the annular outer frame 1 is formed by the relative fastening connection of the first shell 11 and the second shell 12, and the edge of the font back plate 2 is sandwiched between the first shell 11 and the second shell 12. Specifically, both the first shell 11 and the second shell 12 are thin-walled components. After the annular outer frame 1 is formed by fastening in this way, the weight of the annular outer frame 1 can be significantly reduced, thereby reducing the overall weight of the couplet characters. Several solid blocks 108 are integrally provided in the shell cavity of each side frame of the first shell 11 and the second shell 12 to ensure the overall strength of the shell structure. Preferably, the solid blocks 108 in the first shell 11 and the second shell 12 are arranged in groups, and the two solid blocks 108 in the same group are respectively provided with insertion posts 109 and insertion holes 110. The quick fixed connection between the first shell 11 and the second shell 12 is achieved through the mortise and tenon connection between the insertion posts 109 and the insertion holes 110. Example 4:
[0034] The difference between this embodiment and the aforementioned embodiments lies in that: the annular outer frame 1 and the font back plate 2 are integrally molded structures, or the font block 3 and the font back plate 2 are integrally molded structures, or the annular outer frame 1, the font back plate 2, and the font block 3 are integrally molded structures. This integrated structure reduces assembly processes, making it particularly suitable for 3D printing. By changing the color of the filament, a one-piece design can be achieved. When using injection molding, the number of molds required for parts can be reduced, lowering production costs. In the later stages of injection molding, pigments can be applied using a spray painting process to change local colors, achieving color variations between different structures. Example 5:
[0035] like Figure 7 and Figure 8As shown, the difference between this embodiment and the previous embodiments is that the outer shape of the annular outer frame 1 is not limited to a square structure, but can also be other regular or irregular shapes, as long as the distribution directions of the connecting bumps 101 and connecting grooves 102 for hinging are on the four sides of a square. When the outer shape of the annular outer frame 1 is non-square, there are hollow structures at the corners of the hexahedron box enclosed by it, and its internal cavity is suitable for preventing large-volume objects. Embodiment 6:
[0036] A couplet includes a left couplet, a right couplet and a horizontal scroll. Both the left couplet and the right couplet are made by arranging a number of couplet character blocks in any of the previous embodiments up and down and sequentially hinging them head to tail. The horizontal scroll is made by arranging a number of couplet character blocks in any of the previous embodiments left and right and sequentially hinging them.
[0037] As Figure 9 shown, the left couplet of the couplet made of the couplet character blocks in Embodiment 1 is shown. Its specific numbers are determined according to the number of characters in a single couplet. For example, for "A year ends in the sound of firecrackers", the text contents of the font blocks 3 need to correspond to the 7 couplet character blocks of "爆", "竹", "声", "中", "一", "岁", "除" respectively and are sequentially hinged from top to bottom; the structural form of the right couplet is the same as that of the left couplet, and only the Chinese characters corresponding to the corresponding font blocks 3 need to be replaced. As Figure 10 shown, the horizontal scroll of the couplet made of the couplet character blocks in Embodiment 1 is shown. Its specific numbers are determined according to the number of characters in the horizontal scroll. For example, for "Ring out the old year and ring in the new", the text contents of the font blocks 3 need to correspond to the 4 couplet character blocks of "辞", "旧", "迎", "新" respectively and are sequentially hinged from left to right. To conform to the construction style of traditional couplets, the size of the couplet character blocks used in the horizontal scroll should be smaller than the size of the couplet character blocks used in the left couplet and the right couplet. For example, take 1:2, and the structural form can be exactly the same. Embodiment 7:
[0038] As Figure 11 shown, the difference between this embodiment and the above embodiments is that a first connecting plate 4 is hinged to the top ends of both the left couplet and the right couplet, and a second connecting plate 5 is hinged to the bottom ends of both the left couplet and the right couplet. Since the sorting method of the connecting bumps 101 and connecting grooves 102 at the topmost of the left couplet / right couplet and the sorting method of the connecting bumps 101 and connecting grooves 102 at the topmost are centrosymmetrically distributed around the center of the left couplet / right couplet, therefore, to reduce the number of injection moldings and lower the manufacturing cost, the first connecting plate 4 and the second connecting plate 5 adopt exactly the same structure. The overall structural form of the first connecting plate 4 / second connecting plate 5 is the same as the structural form of the couplet character blocks, that is, it is also a structural form of "outer frame + inner plate + character block" to maintain the same style.
[0039] The first connecting plate 4 and the second connecting plate 5 serve as the end action points for the left and right couplets to be suspended and fixed on the vertical plane. Similarly, they are provided with a reserved fixed connection structure similar to the fixed connection hole 105, suspension hole 106 and fixed connection block 202 on the couplet characters.
[0040] like Figure 12 As shown, in order to maintain the style consistency between the horizontal connection and the left / right connection, a third connecting plate 6 and a fourth connecting plate 7 with similar structure but smaller size to the first connecting plate 4 and the second connecting plate 5 are respectively set at the left and right ends of the horizontal connection. Example 8:
[0041] like Figure 13 As shown, a storage box includes a base plate, four side plates respectively hinged to the four sides of the base plate, and a flip-top plate hinged to the top of one of the side plates. The vertical sides of two adjacent side plates are hinged together. The base plate, side plates and flip-top plate all use couplet characters as described in any of the above embodiments 1 to 5.
[0042] After the couplet in Example 6 is used up, it can be removed from the vertical plane. The hinge between the fifth and fourth couplet characters can be removed. Then, the first four couplet characters can be rotated sequentially and connected end-to-end to form a square frame structure. Two characters can then be randomly removed from the remaining couplet characters. One character can be fitted with each of the four edges of the bottom opening of the square frame structure and fixed by the hinge, thus closing the bottom opening. The other character can have one edge fitted with any edge of the top opening of the square frame structure and hinged by the hinge. In this way, the used couplet can be transformed into a cubic storage box for storing household items. Example 9:
[0043] like Figure 14 As shown, this is an example of using the method described in Example 5. Figure 8 The illustration shows a storage box formed by couplet-shaped characters made of a non-standard square outer frame 1. As mentioned earlier, compared with the storage box formed by the couplet-shaped characters in Example 1 in Example 8, this storage box has holes at the corners, so it can only store larger objects to prevent the objects stored inside from falling out through the holes.
[0044] Example 10: like Figure 15As shown, a storage box includes a base plate, four side plates hinged to the four edges of the base plate, and two half-flip-top panels hinged to the tops of two opposing side plates. The vertical sides of adjacent side plates are hinged together. The base plate and side plates use couplet-shaped characters as described in any of Embodiments 1 to 5. The two half-flip-top panels use the first connecting plate 4 and the second connecting plate 5 as described in Embodiment 7. To ensure that the two half-flip-top panels can be fully horizontally fastened to the top opening of the square frame, the length of the two half-flip-top panels matches the width of the couplet-shaped characters, and the sum of the widths of the two half-flip-top panels is not greater than the width of the couplet-shaped characters. Preferably, to facilitate the opening of the half-flip-top panels for easy access to items, recesses are provided on the adjacent sides of the two half-flip-top panels. When the two half-flip-top panels are horizontally fastened to the frame structure, the two recesses form an oblong hole that allows a finger to pass through. The storage box can be opened by flipping the half-flip-top panels upwards with a finger.
[0045] Obviously, two or more couplet modules can be joined side-by-side to form a single sidewall, thus creating a rectangular frame structure. A corresponding number of couplet modules can be placed at the bottom to form a rectangular base, and a corresponding number or fewer couplet modules can be placed at the top to form a complete or partial flip-top structure, thereby constructing a cuboid storage box. Alternatively, the upper and lower sections can be connected to form a taller sidewall, creating a long, cylindrical, vertical storage box. The top flip-top structure can also be omitted, creating an open storage container. Furthermore, the remaining couplet modules can be directly or easily modified for reuse as placemats, tabletop picture frames, etc.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
