Description

Technical Field

[0001] This application relates to the field of furniture equipment technology, specifically to a modular storage device. Background Technology

[0002] Storage devices are widely used in ordinary homes, offices, storage rooms, garages, and public storage rooms. Common storage devices, such as shelves, racks, and lockers, are mostly modular. That is, compared to welded storage devices, the components of modular storage devices can be disassembled, which not only facilitates packaging and transportation but also allows for customization according to the interior space.

[0003] Related modular storage devices, taking shelving units as an example, include multiple vertically arranged columns and multiple horizontally arranged shelves. The columns are combined in pairs and connected by crossbars to form frames, and the shelves are sequentially connected between adjacent frames along the height of the columns. For example, US Patent Application Publication No. US20190328134A1, entitled "Shelving System," includes four columns, multiple support beams, and multiple beam supports. The four columns are combined in pairs to form two frames. The two columns of each frame are connected by crossbars and diagonal braces. Support beams at the same horizontal height are connected between the two front columns and the two rear columns of the two frames. Beam supports for placing items are installed between the two support beams.

[0004] The aforementioned modular storage devices have the following drawbacks in actual installation and use: Since the height of the storage device is generally 1.8 to 2.6 meters, its overall height is relatively high and the uprights are designed as a single piece, resulting in a long length of each upright. This not only increases packaging costs and makes transportation inconvenient, but also makes installation more laborious. In addition, in order to ensure the structural stability of the furniture, multiple horizontal bars and diagonal braces are connected between the two uprights of the frame, resulting in more parts and making assembly more complicated.

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0040] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0041] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] See Figures 1-12 As shown, this application discloses a modular storage device, specifically referring to shelves, bookshelves, or merchandise racks placed on the ground for storage. Taking a shelf as an example, the modular storage device includes at least one shelf, each shelf having a structure comprising at least two frame bodies, and each frame body constituting an independent module. Taking two frame bodies as an example, the two frame bodies are distributed sequentially along the height direction. During assembly, the upper frame body and the lower frame body are spliced ​​and fixed in the height direction. Specifically, each frame body includes two uprights and at least one shelf assembly connected between the two uprights. Each upright includes two vertically arranged and spaced columns. When the upper frame body and the lower frame body are spliced ​​and fixed, the lower ends of the columns of the upper frame body are spliced ​​and fixed to the upper ends of the columns of the lower frame body.

[0044] For example, see Figure 1 , Figure 2 and Figure 3 As shown, the combined storage device includes two frames: a first frame 1 and a second frame 2. The first frame 1 includes four first columns 101, also known as four corner columns, which are respectively set at the four corners of the first frame 1. The two first columns 101 on the left and right sides of the first frame 1 form two first uprights 100. The lower ends of the two first columns 101 of each first upright 100 are fixedly connected by a first crossbar 106. That is, the two first columns 101 and the first crossbar 106 are fixedly connected to form a first upright 100. Multiple first shelves 104 distributed along the height direction of the first frame 1 are connected between the two first uprights 100. The first shelf 104 located at the bottom of the first frame 1 is connected to the bottom of the two first uprights 100 as a base plate. Similarly, the second frame 2 includes four second columns 201, also known as four corner columns, which are respectively set at the four corners of the second frame 2. The two second columns 201 on the left and right sides of the second frame 2 respectively form two second frames 200. The upper ends of the two second columns 201 of each second frame 200 are fixedly connected by a second crossbar 206. That is, the two second columns 201 and the second crossbar 206 are fixedly connected to form the second frame 200. Multiple second layer plates 204 distributed along the height direction of the second frame 2 are connected between the two second frames 200. The second layer plate 204 located at the top of the second frame 2 is connected to the top of the two second frames 200 as a top plate.

[0045] In some embodiments, see Figure 5 and Figure 7As shown, the first horizontal bar 106 has first inserts 1060 at both ends, and the two first columns 101 of the first support frame 100 have first connecting holes 102 at their lower ends. The first inserts 1060 at both ends of the first horizontal bar 106 are inserted into the first connecting holes 102 at the lower ends of the two first columns 101, and the two ends of the first horizontal bar 106 are fastened to the lower ends of the two first columns 101 by fasteners 4. Similarly, the second horizontal bar 206 has second inserts 2060 at both ends, and the two second columns 201 of the second support frame 200 have second connecting holes 202 at their upper ends. The second inserts 2060 at both ends of the second horizontal bar 206 are inserted into the second connecting holes 202 at the upper ends of the two second columns 201, and the two ends of the second horizontal bar 206 are fastened to the upper ends of the two second columns 201 by fasteners 4.

[0046] It is easy to understand that in some embodiments, the four first columns 101 and the four second columns 201 are all metal columns with square cross-sections. Each column is a hollow structure formed by integral bending of sheet metal, and the cross-sectional size of each column is the same. After the upper end of the first column 101 and the lower end of the second column 201 are spliced ​​and fixed, they can form a whole column, and the outer surfaces of the two columns are flush.

[0047] It is understandable that when assembling the upper and lower shelves of this modular storage device, the upper and lower shelves can be assembled separately first. That is, the uprights and shelves of the lower shelf are assembled to form the lower shelf, and the uprights and shelves of the upper shelf are assembled to form the upper shelf. Then, the entire upper shelf is spliced ​​and fixed onto the lower shelf, with the lower ends of the uprights of the upper shelf spliced ​​and fixed to the upper ends of the uprights of the lower shelf. Alternatively, the lower shelf can be assembled first, and then the lower ends of the two uprights of the upper shelf are spliced ​​and fixed to the upper ends of the two uprights of the lower shelf, and finally the shelves of the upper shelf are installed.

[0048] In some embodiments, the two frames of the modular storage device are distributed sequentially along the height direction. During assembly, the lower ends of the columns of the second frame 2 are spliced ​​and fixed to the upper ends of the columns of the first frame 1, so that the columns of the second frame 2 and the columns of the first frame 1 are spliced ​​together to form a single column. That is, the modular storage device divides a single column into two parts, which are spliced ​​together along the length direction during assembly. The length of a single column is reduced, and the weight is reduced. This not only reduces the assembly difficulty and makes the assembly operation simpler, more convenient, and less labor-intensive, but also avoids the defects of large packaging size, high packaging cost, and inconvenience in transportation caused by the long length of the single column. Therefore, the modular storage device is not only small in packaging volume and convenient for transportation, but also simple and convenient to assemble.

[0049] For example, taking a modular storage device with a height of 2.6 meters as an example, the first column 101 of the first frame 1 and the second column 201 of the second frame 2 are each 1.3 meters long. The original 2.6-meter-long column is divided into two 1.3-meter columns. This not only avoids the defects of the storage device having overly long parts that are difficult to package and transport, but also reduces the assembly difficulty when assembling the first frame 1 and the second frame 2 because the columns are lighter, making the assembly operation simpler, more convenient and less labor-intensive.

[0050] It is understandable that, in order to improve storage capacity or storage volume, the overall height of this modular storage device is generally set relatively high. The lower end of the second upright 200 of the second frame 2 is spliced ​​and fixed to the upper end of the first upright 100 of the first frame 1 to form the entire upright. In order to improve the mechanical strength and structural stability of the upright and to facilitate the splicing of the second upright 200 and the first upright 100, in this embodiment, the second frame 2 and the first frame 1 are spliced ​​by a connector 3. Specifically, each upright of the upper frame and each upright of the lower frame are provided with a connector 3. The connector 3 is fastened to the upright of the upper frame and the upright of the lower frame respectively, so that the upright of the upper frame and the upright of the lower frame are spliced ​​and fixed as a whole.

[0051] For example, see Figure 3 and Figure 4 As shown, the connector 3 includes a crossbeam 300 and two connecting plates 301 connected to both ends of the crossbeam 300. The two connecting plates 301 are respectively arranged perpendicularly to the crossbeam 300, and the crossbeam 300 and the two connecting plates 301 are welded to form an H-shaped structure. The upper ends of the two connecting plates 301 are respectively fastened to the lower ends of the two uprights of the upper frame, and the lower ends of the two connecting plates 301 are respectively fastened to the upper ends of the two uprights of the lower frame. Specifically, the lower ends of the two connecting plates 301 are inserted into the first upright 101 of the first frame 1 along the height direction of the first frame 1 and fastened to it by fasteners 4, and the upper ends of the connecting plates 301 are inserted into the second upright 201 of the second frame 2 along the height direction of the first frame 1 and fastened to it by fasteners 4. That is, when the second frame 2 is spliced ​​with the first frame 1, the lower ends of the two connecting plates 301 of the connector 3 are first inserted into the upper ends of the two first columns 101 of the first upright 100 and fastened together by the fastener 4. At this time, the upper ends of the two connecting plates 301 of the connector 3 extend upward. Then, the lower ends of the two second columns 201 of the second upright 200 are inserted into the upper ends of the two connecting plates 301. Finally, the lower ends of the second columns 201 and the upper ends of the connecting plates 301 are fastened together by the fastener 4.

[0052] It is understood that each connecting plate 301 has connecting holes at its upper and lower parts, and the first column 101 has a first mounting hole at its upper end, and the second column 201 has a second mounting hole at its lower end. When the lower end of the second column 201 abuts against the upper end of the first column 101, the second mounting hole of the second column 201 is aligned with the connecting hole at the upper part of the connecting plate 301, and the first mounting hole of the first column 101 is aligned with the connecting hole at the lower part of the connecting plate 301. In this embodiment, the fastener 4 can be a bolt or a screw, and fastening is achieved by the fastener 4 passing through the mounting hole and the connecting hole.

[0053] In some embodiments, the upper ends of the two connecting plates 301 are respectively inserted into the lower ends of the two uprights of the upper frame, and the lower ends of the two connecting plates 301 are respectively inserted into the upper ends of the two uprights of the lower frame. Specifically, the upper end of the upright of the lower frame may be provided with an upward-facing first clearance notch 105, and the lower end of the upright of the upper frame may not be provided with a notch. In this case, a part or the entire end of the beam 300 is accommodated in the first clearance notch 105. During installation, the two ends of the beam 300 may be placed in the two first clearance notches 105 at the upper end of the upright of the lower frame, and then the upper frame may be connected to the lower frame. When the lower end of the upright of the upper frame and the upper end of the upright of the lower frame are joined together, the first clearance notch 105 forms a clearance hole for the beam 300 to pass through. Alternatively, a second clearance notch 205 with a downward opening can be provided only at the lower end of the uprights of the upper frame, while no notch is provided at the upper end of the uprights of the lower frame. A portion or the entire end of the beam 300 is accommodated within the second clearance notch 205. When the lower end of the uprights of the upper frame and the upper end of the uprights of the lower frame are joined together, the second clearance notch 205 forms a clearance hole for the beam 300 to pass through. Optionally, a first clearance notch 105 with an upward opening is provided at the upper end of the uprights of the lower frame to accommodate at least a portion of the beam, and a second clearance notch 205 with a downward opening is provided at the lower end of the uprights of the upper frame to accommodate at least a portion of the beam. When the lower end of the upper frame column abuts against the upper end of the lower frame column, the first clearance notch 105 and the second clearance notch 205 together form a clearance hole for the crossbeam 300 to pass through, thereby achieving a seamless splicing between the lower end of the second column 201 and the upper end of the first column 101. See also Figure 3 and Figure 4 As shown, the cross-section of the beam 300 between the two connecting plates 301 of the connector 3 is rectangular. In order to make the lower end of the second column 201 and the upper end of the first column 101 abut and align during splicing, the first clearance notch 105 can accommodate the lower half of the beam 300, and the second clearance notch 205 can accommodate the upper half of the beam 300.

[0054] Understandably, after the second upright 200 is spliced ​​and fixed to the first upright 100, the crossbeam 300 of the connector 3 acts as the two columns connecting the uprights, making the structure more stable after the second upright 200 is spliced ​​to the first upright 100. That is, for the first upright 100, apart from the first crossbar 106 at the lower end of the two first columns 101, there is no need to set any other first crossbar 106. For the second upright 200, apart from the second crossbar 206 at the upper end of the two second columns 201, there is no need to set any other second crossbar 206, thus simplifying its structure and reducing the difficulty of assembly.

[0055] In the aforementioned embodiment, the two connecting plates 301 of the connector 3 are configured to be respectively inserted into the first column 101 and the second column 201 and fastened together by fasteners 4. In other embodiments, the connecting plates 301 may also be configured as follows: the two connecting plates 301 are disposed on the outer sides of the first column 101 and the second column 201, that is, the upper parts of the two connecting plates 301 are respectively attached to the outer walls of the two second columns 201 and fastened together by fasteners 4, and the lower parts of the two connecting plates 301 are respectively attached to the outer walls of the two first columns 101 and fastened together by fasteners 4. The connecting plate 301 may be configured as a straight plate with a rectangular cross-section, or as a straight plate with an L-shaped cross-section, or as a straight plate with a U-shaped cross-section; in this embodiment, it is not necessary to open the clearance notch for the crossbeam 300 on the first column 101 and the second column 201.

[0056] It is easy to understand that in the aforementioned embodiments, the connecting plates 301 of the connector 3 are all set as straight plates, completely inserted into the inner hole of the column, and the clearance notches at the opposite ends of the upper and lower frame columns are engaged with the crossbeam of the connector 3. In some embodiments, a protruding step structure can also be provided on the side of the connecting plate 301 near the clearance notch of the column. When the upper and lower ends of the connecting plate 301 are inserted into the upper and lower frame columns, the protruding step structure on the connecting plate 301 is precisely engaged in the clearance notch of the upper and lower columns. In this embodiment, the two ends of the crossbeam 300 of the connector 3 are welded and fixed to the protruding step structures on the two connecting plates 301 respectively.

[0057] In some embodiments, the shelving of the modular storage device further includes multiple sets of support beams distributed along the height of the frame. Each set of support beams includes two support beams connected to the front and rear sides of two uprights respectively, and the shelves are supported by the two support beams. Specifically, multiple shelves are connected to both frames along the height direction. Multiple sets of support beams distributed along the height direction are connected between the two uprights of each frame. Each set of support beams includes two support beams connected to the front and rear sides of two uprights respectively, and support plates 2032 are connected to the opposite sidewalls of the two support beams. The shelves are placed between the two support beams and rest on the support plates 2032. That is, when installing the shelves, the two support beams of each set of support beams are first installed on the front and rear sides of the two uprights respectively, and the two support beams are symmetrically arranged. Then, the shelves are placed between the two support beams and rest on the support plates 2032 on the opposite sidewalls of the two support beams. It is understood that the position of the shelves can be changed according to the position of the support beams, that is, the spacing between the shelves is adjustable, and the number of shelves can be selected according to the user's needs.

[0058] For example, see Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the two first uprights 100 of the first frame 1 are provided with multiple sets of first insertion holes 107 along the height direction on the front and rear sides. Each set of first insertion holes 107 includes eight rectangular first insertion holes 107. The first insertion holes 107 are arranged in pairs on the outer side wall of each first column 101. Each first support beam 103 is provided with two insertion plates at both ends: a first upper insertion plate 1030 and a first lower insertion plate 1031. The first upper insertion plate 1030 and the first lower insertion plate 1031 at the end of the first support beam 103 are respectively inserted into the two first insertion holes 107 on the outer side wall of the first column 101. The two ends of the first support beam 103 are respectively fastened to the two first uprights 100 by fasteners 4. The fasteners 4 are arranged between the two insertion plates at the end of the first support beam 103. Similarly, the two second uprights 200 of the second frame 2 are provided with multiple sets of second insertion holes 207 along the height direction on the front and rear sides. Each set of second insertion holes 207 includes eight rectangular second insertion holes 207. The second insertion holes 207 are arranged in pairs on the outer side wall of each second column 201. Each end of each second support beam 203 is provided with two insert plates: a second upper insert plate 2030 and a second lower insert plate 2031. The second upper insert plate 2030 and the second lower insert plate 2031 at the end of the second support beam 203 are respectively inserted into the two second insertion holes 207 on the outer side wall of the second column 201. The two ends of the second support beam 203 are respectively fastened to the two second uprights 200 by fasteners 4. The fasteners 4 are arranged between the two insert plates at the end of the second support beam 203.

[0059] In this design, the two first uprights 100 of the first frame 1 have multiple sets of first insertion holes 107 along the height direction on both the front and rear sides. Each set of first insertion holes 107 can be inserted into the two insert plates at the end of the corresponding first support beam 103, allowing the shelf to have a larger number of layers (shelves). However, some of the first insertion holes 107 can be left unused and not inserted into the two insert plates at the end of the first support beam 103, resulting in a higher interlayer height of the shelf. Hole covers can be inserted into the unused first insertion holes 107 to ensure the overall aesthetics of the shelf.

[0060] It is understandable that, since the second frame 2 is spliced ​​and fixed to the first frame 1 below it, there is a seam between the second frame 2 and the first frame 1. In order to improve the structural stability and load-bearing capacity of the spliced ​​frame, the connecting piece 3 between the first frame 1 and the second frame 2 is securely connected to the uprights of the upper frame, the uprights of the lower frame, and at least one set of support beams, respectively. That is, at the seam between the upper and lower frames, the connection and cooperation of the connecting piece 3 and at least one set of support beams makes the splicing of the upper and lower frames more solid and stable. Therefore, when assembling this combined storage device, the lower end of the upright of the upper frame and the upper end of the upright of the lower frame are spliced ​​and fixed through the connecting piece and support beam, so that the upper and lower frames are firmly fixed in both the height and length directions, thereby making the shelf structurally stable and strong in load-bearing capacity. Specifically in this embodiment, see Figure 6 , Figure 8 and Figure 9 As shown, each first column 101 of the first frame 1 is provided with a first insertion hole 107 at its upper end, and each second column 201 of the second frame 2 is provided with a second insertion hole 207 at its lower end. After the second frame 2 is spliced ​​and fixed to the first frame 1, the first insertion hole 107 at the upper end of each first column 101 and the second insertion hole 207 at the lower end of each second column 201 are combined to form two insertion holes. These two insertion holes allow two insert plates at the end of the support beam to be inserted. The two insert plates at the end of the support beam are respectively inserted into the first insertion hole 107 and the second insertion hole 207. The end of the support beam is fastened to the connector 3 in the joint by fastener 4, which makes the splicing of the joint between the first column 101 and the second column 201 more stable.

[0061] It is easy to understand that in some embodiments, the first insertion hole 107 and the second insertion hole 207 are the same insertion hole, and the first support beam 103 and the second support beam 203 are support beams of the same structure. Support plates 2032 for supporting the shelf are connected to the side walls of both the first support beam 103 and the second support beam 203. The support plates 2032 welded to the opposite side walls of the two support beams in each set of support beams provide support for the bottom of the shelf. When the shelf is placed on the support plate 2032 between the two support beams, the top surface of the shelf is flush with the top surface of the support beam. The support beam can be a single complete pipe fitting, or it can be formed by splicing two or more pipe fittings (such as splicing two or more telescopic sleeves).

[0062] In some other embodiments, the support beam may be a sheet metal part with a U-shaped, L-shaped or other shape in cross section, and a part of the support beam forms a support plate of the support layer.

[0063] In some other embodiments, the shelving of the combined storage unit also includes multiple sets of crossbars (e.g. Figure 5 , Figure 7 The first crossbar 106 and the second crossbar 206 are shown. The crossbars are positioned between the two uprights of each frame. Multiple sets of crossbars are distributed along the height of the frame. Each set of crossbars includes two crossbars connected to the left and right sides of the two uprights respectively. The shelves are supported by the two crossbars. Specifically, multiple shelves are connected to both frames along their height. Multiple sets of crossbars are connected between the two uprights of each frame. Each set of crossbars includes two crossbars connected to the left and right sides of the two uprights respectively. Support plates are connected to the opposite side walls of the two crossbars. The shelves are positioned between the two crossbars and rest on the support plates. That is, during shelf installation, the two crossbars of each set are first installed on the left and right sides of the two uprights, symmetrically arranged. Then, the shelves are placed between the two crossbars and rest on the support plates on the opposite side walls of the two crossbars. It is understood that the position of the shelves can be changed according to the position of the crossbars; that is, the spacing between shelves is adjustable, and the number of shelves can be selected according to the user's needs. In addition, to enhance the load-bearing capacity of the shelves, at least one support beam can be connected between each set of crossbars. The upper surface of the support beam is flush with the upper surface of the support plate on the side wall of the crossbar. The shelves are placed between two crossbars and rest on the support plate and support beam on the opposite side walls of the two crossbars.

[0064] In other embodiments of this modular storage device, the shelves are directly attached to the uprights. For example, the shelves and uprights are connected by screws or bolts. Alternatively, a connecting seat is provided on the upright, and the shelves are hung on the connecting seat.

[0065] Further, in some embodiments, see Figure 11 and Figure 12As shown, the shelf includes an outer shell integrally bent from a metal sheet and multiple support rods 2040 distributed along the length of the outer shell and connected inside the outer shell. That is, the shelf is a hollow structure, and the internal support rods 2040 serve to enhance mechanical strength and improve load-bearing capacity.

[0066] In some embodiments, the shelf can also be a mesh panel or a solid wood panel, wherein the mesh panel is a metal mesh panel formed by welding metal rods in a crisscross pattern, and the mesh panel can be connected within a rectangular frame to form a shelf. The length of the shelf can be adapted to the length of the frame.

[0067] In some embodiments, see Figure 21 and Figure 22 As shown, the shelving unit consists of three frames arranged sequentially along its height. Specifically, an intermediate frame 11 is positioned between the first frame 1 and the second frame 2. This intermediate frame 11 has two intermediate uprights 1100 on the left and right. Each intermediate upright 1100 includes two vertically arranged and spaced-apart intermediate columns 1101. A set of intermediate support beams 1102 and an intermediate shelf 1103 connect the two intermediate uprights 1100. In this embodiment, a connector 3 is provided between the first frame 1 and the intermediate frame 11. This connector 3 is securely connected to the uprights of the intermediate frame 11, the uprights of the first frame 1, and at least one set of first support beams 103. Similarly, a connector 3 is provided between the second frame 2 and the intermediate frame 11. This connector 3 is securely connected to the uprights of the intermediate frame 11, the uprights of the second frame 2, and at least one set of second support beams 203. This shelving unit is a three-tiered structure, further enhancing its storage capacity.

[0068] It is easy to understand that, in order to improve the storage space expansion capability of the modular storage device and meet the storage needs of consumers, at least one frame is connected to a perforated plate 5. The perforated plate 5 is essentially a bent sheet metal, and the sheet metal is evenly distributed with holes or openings. Functional accessories suitable for storage, such as hanging rods, hooks, shelves, storage baskets, etc., as well as other decorative items such as picture frames and potted plants, can be inserted into these holes or openings.

[0069] For example, see Figure 13 and Figure 14As shown, perforated panels 5 are installed on the two first uprights 100 of the first frame 1, and perforated panels 5 are installed on the two second uprights 200 of the second frame 2. The perforated panels 5 of this combined storage device can be installed separately or as a whole. For example, the perforated panels 5 can be installed on the second uprights 200 of the second frame 2, and the perforated panels 5 extend downward to the bottom of the first uprights 100 of the first frame 1. The width of the perforated panels 5 is the same as the distance between the two uprights of each frame, and the edges of the perforated panels 5 are connected to the opposite side walls of the two uprights of the frame by fastening screws or hooks.

[0070] Understandably, the installation of the pegboard 5 can be customized according to user needs. For example, the pegboard 5 can be installed only on one side of two shelves, or on the upright of one of the shelves. The pegboard 5 not only improves the storage space expansion capability of the modular storage device, but also acts as a seal on both sides of the shelf, blocking items on the shelf and preventing them from falling off.

[0071] In some embodiments, to improve the concealment or dustproof capability of the storage device, a door panel 6 and a back panel can be connected between the two uprights of the frame. The door panel 6, back panel, and shelves form a concealed storage space. Opening the door panel 6 allows for storage or retrieval of items, while closing the door panel 6 protects the items within the storage space. See details. Figure 15 and Figure 16 As shown, perforated panels 5 are installed on the two first uprights 100 of the first frame 1 and the two second uprights 200 of the second frame 2. Back panels are installed on the back of both frames, and door panels 6 are installed on the front of both frames. The door panels 6 are positioned between the two uprights and between adjacent shelves, meaning they are openable and closable. The door panels 6 enable the storage device to form a storage cabinet. The door panels 6 can be configured such that their outer edges are rotatably connected to the support beams; see details below. Figure 15 As shown, two rotatable door panels 6 are arranged along the length of the frame between every two adjacent shelves. Each door panel 6 has vertically arranged, coaxial elastic pins 600 at its upper and lower ends near the support frame. Each elastic pin 600 includes a pin shaft and a spring sleeved on the pin shaft. The pin shaft can move axially to compress the spring, causing the free end of the pin shaft to extend or retract into the door panel. Coaxial shaft holes are provided on two adjacent upper and lower support beams. The free ends of the two elastic pins 600 at the upper and lower ends of the door panel 6 are respectively inserted into the shaft holes on the two adjacent support beams and can rotate within the shaft holes. When installing the door panel 6, the elastic pins 600 are compressed and aligned with the shaft holes on the support beams. Then, the elastic pins are released, allowing the free end of the pin shaft to be inserted into the shaft hole. Installation is simple, convenient, and labor-saving.

[0072] In some embodiments, the door panel may also be rotatably connected to the frame via hinges, such as rotary hinges, or via pivots.

[0073] In some embodiments, the door panel 6 may also be configured such that the top of the door panel 6 is rotatably connected to the shelf, see [reference]. Figure 16 As shown, a door panel 6 is provided between adjacent shelves. The opposite side walls of the left and right uprights below the upper shelf are provided with sliding grooves extending along the width or depth of the shelf. The top two sides of the door panel 6 are respectively provided with protruding columns. The columns slide in the two sliding grooves. When the door panel 6 rotates about the axis of the column to be horizontal or aligned with the length of the sliding groove, the door panel can be pushed inward into the shelf. After the door panel 6 is pulled outward, it can rotate downward about the axis of the column to close the storage space between the upper and lower shelves. Therefore, when storing items, the door panel 6 can be opened simply by flipping it upward and pushing it into the sliding groove on the upright.

[0074] In some embodiments, a door panel 6 is provided between adjacent shelves. The upper edge of the door panel 6 can also be rotatably connected to the support beam on the outside of the upper shelf via a hinge, and the door panel can be opened by flipping it upwards.

[0075] In other embodiments, a door panel or perforated panel is connected between two uprights of at least one of the frame structures, or a door panel or perforated panel is connected between at least two adjacent support beams, or a door panel or perforated panel is connected to an upright of at least one of the frame structures.

[0076] In other embodiments, the door panel of the above embodiment can be replaced with a curtain, that is, a slidable curtain that can be opened or closed is connected to one side of the shelf of at least one frame, and the curtain extends downward along the height direction of the frame. Specifically, a guide rail extending along the length direction of the support beam can be connected to one side of the top support beam of the second frame 2, and the upper edge of the curtain is slidably connected to the guide rail, and the curtain can be opened or closed along the length direction of the guide rail.

[0077] It is understood that each shelf in this modular storage unit is an independent furniture module, and the shelves can be assembled together; therefore, users can choose the appropriate number of shelves to assemble according to the size of their indoor space. (See [link]). Figure 17 and Figure 18As shown, the modular storage device includes a first shelf and a second shelf. The first shelf includes a first frame 1 and a second frame 2, and the second shelf includes a third frame 7 and a fourth frame 8. In this embodiment, the number of frames is set to four: the first frame 1, the second frame 2, the third frame 7, and the fourth frame 8. The lower ends of the uprights of the second frame 2 are spliced ​​and fixed to the upper ends of the uprights of the first frame 1 to form the first shelf, and the lower ends of the uprights of the fourth frame 8 are spliced ​​and fixed to the upper ends of the uprights of the third frame 7 to form the second shelf. The first and second shelves are arranged side by side, and a connecting frame 9 is provided between them. The two ends of the connecting frame 9 are detachably connected to the tops of the first and second shelves, respectively. That is, the first and second shelves can be connected as a whole through the connecting frame 9 to meet the user's storage needs. Similarly, perforated panels 5 are installed on the left and right sides of the first and second shelves.

[0078] In the foregoing embodiments, to facilitate the connection of the connecting frame 9 with the first and second shelves, making assembly simpler and more convenient for the user. See also Figure 18 , Figure 19 and Figure 20 As shown, the connecting frame 9 is welded from a metal rod, and each end of the connecting frame 9 is equipped with a hook 900 with its opening facing downwards. The hooks 900 at both ends of the connecting frame 9 are respectively hooked to the top of the two opposing uprights of the first and second shelves. That is, during installation, it is only necessary to hook the hooks 900 at both ends of the connecting frame 9 to the first and second shelves, which is simple and convenient to operate.

[0079] In order to further improve the storage capacity of the storage device and expand the storage space, at least one horizontally arranged shelf 901 is connected to the connecting frame 9. Specifically, shelves 901 are connected to the top and bottom of the connecting frame 9, and the shelves 901 extend along the length of the connecting frame 9. Items can be placed on the shelves 901.

[0080] In the above embodiment, a table 10 is provided between the first shelf and the second shelf. The table 10 is located below the connecting frame 9. Users can work on the table 10 as a desk, thereby further improving the functionality of the combined storage device.

[0081] In some embodiments, a horizontally arranged table can also be connected between the first shelf and the second shelf, with the two sides of the table connected to the first shelf and the second shelf respectively.

[0082] In some embodiments, with Figure 1 , Figure 2 , Figure 3 and Figure 15Taking the illustrated shelving unit as an example, all components, including uprights, shelves, support beams, crossbars, and connectors, are either scattered or disassembled during factory packaging. Users can install the shelving unit in the following order: S1: Assemble the upper and lower frames respectively; specifically, connect the two first columns 101 through the first crossbar 106 to form the first frame 100, until the two first frames 100 are assembled; connect the two second columns 201 through the second crossbar 206 to form the second frame 200, until the two second frames 200 are assembled. S2: Assemble the frames separately; specifically, place the two first uprights 100 from step S1 vertically, connect the two first support beams of each set of first support beams 103 to the front and rear sides of the two first uprights 100 respectively, and fasten them with fasteners to form the first frame 1; place the two second uprights 200 from step S1 vertically, connect the two second support beams of each set of second support beams 203 to the front and rear sides of the two second uprights 200 respectively, and fasten them with fasteners to form the second frame 2; S3: Frame assembly; Specifically, firstly, insert the lower end of the connecting plate 301 of the connector 3 into the upper end of the two first columns 101 of the first upright 100 of the first frame 1 and fasten it with fasteners until the two connectors 3 are installed; secondly, fit the lower end of the two second columns 201 of the second upright 200 of the second frame 2 onto the upper end of the connecting plate 301 of the connector 3 and fasten it with fasteners; then, set the two support beams of a set of support beams on the front and rear sides of the shelf respectively, and insert the two insert plates at each end of the support beam into the first insertion hole 107 at the upper end of the first column 101 and the second insertion hole 207 at the lower end of the second column 201 respectively and fasten them with fasteners 4 until the two support beams are installed; S4: Attachment installation; specifically, install perforated board 5, back panel and door panel 6, etc. on the splicing frame formed in step S3.

[0083] Understandably, when assembling this shelving unit, the uprights and crossbars are first assembled to form a frame. The frame is then fixed by support beams to form a single frame. The frames are then spliced ​​together to form the shelving unit. Finally, accessories such as pegboards 5, back panels, and door panels 6 or curtains are installed to transform the shelving unit into a storage cabinet. Its assembly is simple, convenient, and labor-saving.
