Technology Field
[0001] The present invention relates to a modular storage unit that allows multiple storage boxes to be easily assembled and disassembled. Background Technology
[0003] Generally, storage units used to organize and store items in homes or offices are made of wood, metal, or synthetic resin, and are available in various sizes and structures depending on the purpose of use and the space. Recently, methods involving stacking or combining plastic storage boxes have become widely used, considering their lightweight nature and ease of assembly.
[0004] Conventional plastic storage units of this type typically feature a structure where individual boxes are simply stacked, or where boxes are inserted into a separate frame or support structure. Additionally, some technologies utilize protrusions and grooves on the boxes themselves or simple interlocking methods to connect the boxes.
[0005] However, storage cabinet structures based on conventional technology have the following problems. First, in the case of a simple stacking method, there is a risk that the boxes may easily slide or collapse due to external impact or load, resulting in reduced stability. Second, structures utilizing frames involve a cumbersome assembly process and require separate parts, which increases manufacturing costs and makes it difficult to freely expand or reconfigure the form desired by the user. Third, joining structures using protrusions and grooves on the boxes themselves may experience wear or damage during repeated joining and disassembly, and structural stability deteriorates over long-term use due to insufficient joining strength. Fourth, conventional structures have the disadvantage of limited modular expandability and usability because it is difficult to achieve robust joining in various directions (up, down, left, and right).
[0006] Therefore, there is a need for the development of technology for a new type of modular storage unit structure that allows multiple plastic boxes to be easily assembled and stably combined, and can be freely expanded and reconfigured according to user needs.

[0033] Hereinafter, a preferred embodiment of a prefabricated storage unit according to the present invention will be described with reference to the attached drawings. For reference, in the description of the present invention below, terms referring to the components of the present invention are named considering the functions of each component, and therefore should not be understood as limiting the technical components of the present invention.
[0035] Referring to FIGS. 1 to 4b, the prefabricated storage cabinet according to the present invention is a storage cabinet that can be manufactured in a shape and size desired by a user by combining a plurality of storage boxes (100) in a horizontal and vertical direction, and includes at least two storage boxes (100), a fastening groove (200) provided in the storage box (100), and a fastening member (300) inserted into the fastening groove (200) to combine the storage boxes (100).
[0036] The storage box (100) is formed in a cuboid shape having a storage space. The storage box (100) can be manufactured, for example, by plastic injection molding, and may be a box with an open top surface, closed sides, and a mesh-shaped grid structure on the bottom surface.
[0037] The fastening groove (200) is provided on the upper edge (110) of the storage box (100). The fastening groove (200) may be formed in multiple numbers on the upper edge (100) of the storage box (100) at a certain distance from each other. Here, the fastening groove (300) is formed by cutting a part of the upper edge (110) and a part of the side (120) of the storage box (100), and is formed in a shape corresponding to the shape of half of the fastening member (300).
[0038] A fastener (300) is inserted and fastened into a fastening groove (200) of a storage box (100) to combine two adjacent storage boxes (100). Here, when two adjacent storage boxes (100) are stacked side by side in a horizontal direction and / or a vertical direction, the respective fastening grooves (200) of the two adjacent storage boxes (100) are positioned adjacent to each other, and in this state, one fastener (300) can be inserted and fastened into two adjacent fastening grooves (200) to combine the two adjacent storage boxes (100).
[0039] Specifically, the fastening member (300) includes a first insertion part (310) inserted into a fastening groove (200) of a first storage box, which is one of two adjacent storage boxes (100); a second insertion part (320) inserted into a fastening groove (200) of a second storage box, which is the other of two adjacent storage boxes (100); and a connecting part (330) connecting the first insertion part (310) and the second insertion part (320). The first insertion part (310) and the second insertion part (320) each have a plate-shaped structure extended in a vertical direction and have a shape that is symmetrical to each other with respect to the connecting part (330). The connecting part (330) has a plate-shaped structure extended horizontally from the center portion of each of the first insertion part (310) and the second insertion part (320). The first insertion part (310), the second insertion part (320), and the connecting part (330) of the fastener (300) can be formed as an 'H' shaped structure when viewed from above.
[0040] The fastening groove (200) of the storage box (100) includes a first fastening groove (210) into which the first insertion part (310) or the second insertion part (320) of the fastening member (300) is inserted, and a second fastening groove (220) into which half of the connecting part (330) is inserted. The first fastening groove (210) is formed by cutting a predetermined depth along a vertical downward direction from the upper edge (110) of the storage box (100). The second fastening groove (220) communicates with the first fastening groove (210) and is formed by cutting a smaller width than the first fastening groove (210) from the side (120) of the storage box (100). That is, the first fastening groove (210) of the fastening groove (200) has its upper surface open toward the upper edge (100) of the storage box (100) and its side surface open toward the second fastening groove (220), and the second fastening groove (220) has its upper surface open toward the upper edge (110) of the storage box (100) and its side surface open toward the outer surface of the storage box (100), and is formed in a shape that corresponds to the shape of half of the fastening member (300) overall (see FIG. 5c).
[0041] Accordingly, when two adjacent storage boxes (100) are arranged side by side in a horizontal or vertical direction, the overall shape of the two adjacent fastening grooves (200) corresponds to the shape of the fastener (300), and in this state, the two storage boxes (100) can be simply combined by inserting one fastener (300) into the two adjacent fastening grooves (200).
[0042] Preferably, the first insertion part (310) and the second insertion part (320) of the fastener (300) are provided with a tapered insertion end (340) that extends downward by a predetermined length at the bottom and becomes narrower in width as it goes downward. By the configuration of the insertion end (340) of the fastener (300), the fastener (300) can be easily inserted into the fastening groove (200), and the first insertion part (310), the second insertion part (320), and the connecting part (330) of the fastener (300) can be inserted and fixed in the first fastening groove (210) and the second fastening groove (220) of the fastening groove (200) in a snap-fit manner.

Specifically, the insertion end (340) of the fastener (300) may be formed as a protrusion that protrudes outward by a predetermined width. Additionally, the fastener groove (200) is provided with a third fastener groove (230) in which the protrusion (340) of the fastener (300) is caught and fixed. This third fastener groove (330) is formed on the opposite side of the second fastener groove (320) and is cut laterally toward the first fastener groove (310) to communicate with the storage space of the storage box (100). When the fastener (300) is inserted into the fastening groove (200), the protrusion (340) of the fastener (300) is inserted into the third fastening groove (330) via the second fastening groove (220) and is fixed by being caught on the top of the second fastening groove (220).
[0044] By the configuration of the protrusion (340) of the fastener (300) and the third fastening groove (230) of the fastening groove (200), the fastener (300) can be firmly coupled to the fastening groove (200) of the storage box (100). Furthermore, when a user wishes to disassemble the assembled storage boxes, the fastener (300) can be easily removed from the third fastening groove (230) by pressing the protrusion (340) of the fastener (300), which protrudes inwardly into the storage box (100) through the third fastening groove (330), outwardly.
[0045] Preferably, the protrusion (340) of the fastener (300) has a wider width than the first insertion part (310) and the second insertion part (320) and has a tapered shape that narrows downward. Additionally, the protrusion (340) may include a first protruding end (341) that protrudes toward the third fastening groove (330) of the fastening groove (200) and is fixed by being caught in the third fastening groove (330), and a second protruding end (342) that protrudes in the opposite direction to the protrusion direction of the first protruding end (341), that is, toward the second fastening groove (220) and is fixed by being caught in the second fastening groove (220). By the locking of the first protruding end (341) and the second protruding end (342) of the fastening member (300) and the third fastening groove (230) and the second fastening groove (220) of the fastening groove (200), the fastening member (300) can be more firmly coupled to the fastening groove (200) of the storage box (100).
[0046] Additionally, the fastener (300) may further include a tension providing part (350) having a width smaller than that of the first insertion part (310) or the second insertion part (320) between the protrusion (340) and the first insertion part (310) or the second insertion part (320). This tension providing part (350) is formed with a width smaller than that of the upper first insertion part (310) or the second insertion part (320) and the lower protrusion (340), and serves to ensure that the protrusion (340) has sufficient tension in the lateral direction. Accordingly, when the fastener (300) is inserted into the fastening groove (200), the protrusion (340) has sufficient tension due to the tension providing part (350), so that the protrusion (340) can be easily fastened to the fastening groove (200), and at the same time, the protrusion (340) can be easily removed from the fastening groove (200).
