Description

Folding cabinet Technical Field

[0001] This application relates to the field of locker technology, and in particular to a folding locker. Background Technology

[0002] In related or traditional technologies, storage cabinets can be provided to users in a fully assembled or disassembled state. When provided to users in a disassembled state, users need to assemble the cabinets themselves, which increases the difficulty of assembly.

[0003] From the user's perspective, fully assembled lockers are convenient to use at any time. However, fully assembled lockers require significant packaging and space during transportation, increasing shipping costs. Furthermore, manufacturers need sufficient storage space to store the fully assembled lockers. However, limited inventory / display space results in a smaller number of lockers available for purchase, thus reducing the number available to users. Summary of the Invention

[0004] According to various embodiments of this application, a folding cabinet is provided that reduces assembly difficulty while decreasing the volume after folding.

[0005] This application provides a folding cabinet, including a panel structure. The panel structure includes a front panel and a rear panel arranged sequentially from front to back, and two side panels arranged sequentially from left to right. The front and rear side walls of the side panels are rotatably connected to the front panel and the rear panel, respectively. The side panels are folding panels that allow the front panel and the rear panel to move closer or further apart from each other in the front-back direction. When the panel structure is in a folded state with the front panel and the rear panel close to each other, the folding panels are stored between the front panel and the rear panel.

Detailed Implementation

[0024] As shown in Figures 1 to 15, this application provides a folding cabinet. As shown in Figures 1 and 2, the folding cabinet includes a panel structure 1, which includes a front panel 11, a rear panel 12, and two side panels 13 spaced apart along the left-right direction. The front panel 11 and rear panel 12 are arranged sequentially from front to back, and the front and rear side walls of the side panels 13 are rotatably connected to the corresponding front panel 11 and rear panel 12, respectively. That is, the front side wall of the side panel 13 is rotatably connected to the front panel 11, and the rear side wall of the side panel 13 is rotatably connected to the rear panel. Furthermore, the side panels 13 are folding panels that allow the front panel 11 and rear panel 12 to move closer or further apart along the front-back direction. When the panel structure 1 is folded with the front panel 11 and rear panel 12 close together, the folding panels are stored between the front panel 11 and rear panel 12.

[0025] This application has the following advantages:

[0026] Since the side panel 13 is a foldable panel, the rear panel structure 1 can be folded by folding the side panel 13, reducing the volume of the folded cabinet, facilitating transportation, and reducing packaging costs. In addition, the side panel 13 is foldable and is always hinged to the front panel 11 and the rear panel 12, eliminating the need to assemble the panel structure 1, thus reducing the assembly difficulty of the folding cabinet and better meeting the needs of users.

[0027] It should be noted that the aforementioned front panel 11 includes at least one cabinet door.

[0028] In one embodiment, the side panel 13 includes at least two sleeve plates that are sequentially fitted together along the front-to-back direction, and the side panel 13 is folded by being sequentially fitted together inside and out. In this embodiment, as shown in Figures 1, 2, 4, and 5, the front and rear side walls of the side panel 13 are hinged to the front panel 11 and the rear panel 12, respectively. That is, the front side wall of the side panel 13 is hinged to the front panel 11, and the rear side wall of the side panel 13 is hinged to the rear panel. The side panel 13 includes at least two side panel units 131 that are sequentially hinged together along the front-to-back direction. When the enclosure structure 1 is in the folded state, each side panel unit 131 of the side panel 13 is arranged side by side with the front panel 11 and the rear panel 12.

[0029] Understandably, the side panel 13 can be folded and unfolded by hinged connection of at least two side panel units 131, and the entire folding and unfolding process is convenient. At the same time, the hinged connection of the side panel units 131 ensures that the top walls and bottom walls of each side panel unit 131 are flush, thus ensuring the aesthetics of the folding cabinet.

[0030] Furthermore, as shown in Figures 1, 2, and 4, the aforementioned folding cabinet also includes two cabinet panels 2 arranged at relative intervals along the vertical direction. The enclosure structure 1 and the two cabinet panels 2 together form the cabinet body. The upper cabinet panel 2 is the top panel 200 of the folding cabinet, and the lower cabinet panel 2 is the bottom panel 201 of the folding cabinet. The installation method of the two cabinet panels 2 is basically the same as that of the front panel 11 and the rear panel 12. The following description uses one of the cabinet panels 2 as an example.

[0031] Specifically, as shown in Figures 1 and 2, the cabinet panel 2 includes a first side wall 21 and a second side wall 22 arranged at relative intervals along the front-back direction. The position of the cabinet panel 2 near the first side wall 21 is rotatably connected to one of the front panel 11 and the rear panel 12. The rotation axis of the cabinet panel 2 extends along the left-right direction. The second side wall 22 of the cabinet panel 2 is detachably connected to the corresponding position of the enclosure structure 1. When the enclosure structure 1 is in a folded state, an accommodating space is formed between the front panel 11 and / or the rear panel 12 and the side panel 13. The second side wall 22 of the cabinet panel 2 is disengaged from the corresponding position of the enclosure structure 1, and the second side wall 22 of the cabinet panel 2 rotates into the accommodating space until it is stored in the accommodating space.

[0032] Understandably, the cabinet panel 2 is rotatably connected to the enclosure structure 1 near the first side wall 21, and the second side wall 22 of the cabinet panel 2 is detachably connected to the enclosure structure 1. Therefore, the cabinet panel 2 can be stored in the folding space in the folded state simply by detachably connecting the second side wall 22 to the enclosure structure 1, reducing the volume of the folding cabinet. Furthermore, the second side wall 22 can be rotated outward to connect with the corresponding position of the enclosure structure 1 simply by unfolding the side panel 13, thus realizing the unfolding of the folding cabinet. The entire folding and unfolding process is convenient. At the same time, it avoids the cumbersome disassembly and assembly and the easy loss caused by the detachable connection of both the first side wall 21 and the second side wall 22.

[0033] Furthermore, as shown in Figures 1 and 2, the enclosure structure 1 also includes a front frame located around the front panel 11 and a rear frame located around the rear panel 12. One of the front and rear frames is a first frame 14, and the other is a second frame 15. The enclosure structure 1 forms a storage space 103. The cabinet panel 2 is rotatably connected to the first frame 14 near the first side wall 21, and the second side wall 22 of the cabinet panel 2 is detachably connected to the second frame 15. It can be understood that the presence of the front and rear frames increases the overall strength of the enclosure structure 1, and at the same time, facilitates the installation of the front panel 11, rear panel 12, cabinet panel 2, and side panel 13.

[0034] There are several ways to achieve the above-mentioned rotating connection. One method is to use connecting shafts, where connecting shafts are provided on both the left and right side walls of the cabinet panel near the first side wall, and the first frame has shaft holes at the corresponding connecting shaft positions. Specifically, as shown in Figures 1-11, both the first frame 14 and the second frame 15 include two vertical beams 161 spaced apart along the left-right direction and two horizontal beams 162 spaced apart along the up-down direction. The horizontal beams 162 are arranged along the left-right direction, and the panel 23 of the cabinet panel 2 facing the storage space 103 is hinged to the horizontal beams 162 of the first frame 14. The vertical beams 161 are arranged vertically. In this embodiment, the left and right ends of the second side wall 22 of the cabinet panel 2 are detachably connected to the two vertical beams 161 of the second frame 15 via connecting structures 3. In other embodiments, the second side wall 22 of the cabinet panel 2 is detachably connected to the horizontal beams 162 of the second frame 15.

[0035] As shown in Figures 12 and 13, when the enclosure structure 1 is in a folded state, the accommodating space formed between one of the front panel 11 and the rear panel 12 and the side panel 13 is defined as the first space 101, and the accommodating space formed between the other of the front panel 11 and the rear panel 12 and the side panel 13 is defined as the second space 102. The cabinet panel 2 is stored in the first space 101.

[0036] In this embodiment, the first frame 14 is the rear frame and the second frame 15 is the front frame. Therefore, for the top cabinet panel 2 (i.e., the top panel 200), the first side wall 21 of the cabinet panel 2 is the rear side wall, the panel surface 23 of the top panel 200 is the bottom surface, and the bottom surface of the upper crossbeam 162 of the rear frame is hinged to the bottom surface of the top panel 200.

[0037] As shown in Figures 1 to 8, the second sidewall 22 (i.e., the front sidewall) of the top plate 200 is detachably connected to the upright beam 161 of the front frame. For the bottom cabinet panel 2 (i.e., the bottom plate 201), the first sidewall 21 of the bottom plate 201 is the rear sidewall, the panel surface 23 of the bottom plate 201 is the top surface, the top surface of the lower crossbeam 162 in the rear frame is hinged to the top surface of the bottom plate 201, and the second sidewall 22 (i.e., the front sidewall) of the bottom plate 201 is detachably connected to the upright beam 161 of the front frame. Furthermore, in this embodiment, the first space 101 is located between the rear plate 12 and the side plate 13, and the second space 102 is located between the front plate 11 and the side plate 13.

[0038] In other embodiments, the first frame 14 is the front frame, and the second frame 15 is the rear frame. Furthermore, in some other embodiments, the bottom of the rear sidewall of the top plate 200 is hinged to the rear frame, and the front sidewall of the top plate 200 is detachably connected to the front frame. The top of the front sidewall of the bottom plate 201 is hinged to the front frame, and the rear sidewall of the bottom plate 201 is detachably connected to the rear frame. In some other embodiments, the bottom of the front sidewall of the top plate 200 is hinged to the front frame, and the rear sidewall of the top plate 200 is detachably connected to the rear frame. The top of the rear sidewall of the bottom plate 201 is hinged to the rear frame, and the front sidewall of the bottom plate 201 is detachably connected to the front frame.

[0039] As shown in Figures 5 and 6, the above-mentioned connection structure 3 can be installed using connectors (which can be screws or bolts) or using a snap-fit ​​structure. However, from the perspective of installation reliability and ease of disassembly and assembly, in this embodiment, the connection structure 3 includes a plug rod 31 set on the cabinet panel 2, and the upright beam 161 has a through hole 1611 at the position corresponding to the plug rod 31 to constrain the plug rod 31.

[0040] Furthermore, the connecting structure 3 also includes an elastic element 32 that ensures the insertion rod 31 always tends to move towards the through hole 1611. The elastic element 32 acts on the insertion rod 31. Under the action of the elastic element 32, the insertion rod 31 can be automatically inserted into the through hole 1611, facilitating the installation of the cabinet panel 2 and the side panel 13.

[0041] Specifically, the aforementioned connecting structure 3 further includes a connecting plate 331, which is disposed on the inner wall surface of the cabinet panel 2 facing the accommodating space. The insertion rod 31 passes through the connecting plate 331, and a baffle 311, fixed relative to the insertion rod 31, is disposed on the outer peripheral wall of the insertion rod 31. The baffle 311 is located between the through hole 1611 and the connecting plate 331, and the elastic element 32 is a spring sleeved around the insertion rod 31, with both ends of the spring abutting against the baffle 311 and the connecting plate 331, respectively. In this embodiment, the connecting structure 3 includes a cover 33, which is disposed on the inner wall surface of the cabinet panel 2 facing the accommodating space. The connecting plate 331 is the end plate of the cover 33 away from the through hole 1611, and both the baffle 311 and the elastic element 32 are located within the space enclosed by the cover 33 and the inner wall surface of the cabinet panel 2.

[0042] In addition, to facilitate operation of the insertion rod 31, a handle portion 312 is provided on the insertion rod 31, and the aforementioned baffle 311 is located between the handle portion 312 and the through hole 1611. The baffle 311 can be integrally formed on the insertion rod 31, or the baffle 311 can be detachably installed on the insertion rod 31. In this embodiment, the handle portion 312 is formed by bending the insertion rod 31.

[0043] To increase the reliability of the installation of the second side wall 22 of cabinet panel 2 and side panel 13, the insert rod 31 includes a threaded section 310 that can pass through the through hole 1611, and the aforementioned baffle 311 is located between the threaded section 310 and the connecting plate 331. The connecting structure 3 also includes a fastener 34 that is threadedly connected to the threaded section 310, and the fastener 34 is located outside the through hole 1611. Thus, when assembling the folding cabinet, the insert rod 31 is first inserted into the through hole 1611, and then the threaded section 310 of the insert rod 31 is connected to the fastener 34 by rotating the insert rod 31, thereby achieving a tight connection between cabinet panel 2 and side panel 13. At the same time, by reducing the gap between cabinet panel 2 and side panel 13, the overall stability and load-bearing capacity of the folding cabinet are increased.

[0044] When assembling (unfolding) the folding cabinet, the cabinet panel 2 needs to be rotated. For this rotation, a gap is required between the cabinet panel 2 and the first frame 14 and the second frame 15. This gap can cause wobbling, reducing safety and stability. To avoid wobbling due to excessive gaps, as shown in Figures 9-11, the second sidewall 22 of the cabinet panel 2 and the second frame 15 are fitted with interlocking protrusions 221 and grooves 1621. One of the protrusions 221 and grooves 1621 is located on the second sidewall 22, and the other is located on the second frame 15. It can be understood that during assembling the folding cabinet, the limiting fit of the protrusions 221 and grooves 1621 increases the stability of the second sidewall 22 of the cabinet panel 2 after installation with the second frame 15.

[0045] In this embodiment, as shown in Figures 9-11, the protrusion 221 is disposed on the second sidewall 22, and the groove 1621 is located on the second frame 15. Specifically, the protrusion 221 is a raised rib extending in the left-right direction, and the groove 1621 is a strip-shaped groove extending in the left-right direction, and the groove 1621 is located on the crossbeam 162 of the second frame 15. In other embodiments, the protrusion is disposed on the crossbeam 162 of the second frame 15, and the groove is located on the second sidewall 22. In still some embodiments, the protrusion extends in the up-down direction.

[0046] Because the side panel 13 needs to be rotated to fold during the assembly (unfolding) of the folding cabinet, gaps will exist between the side panel 13 and the front panel 11 and the rear panel 12. These gaps can cause wobbling, reducing safety and stability. To avoid wobbling caused by excessive gaps, the enclosure structure 1 has an unfolded state, as shown in Figures 1-5 and Figure 14. In the unfolded state, the side panel 13 is arranged along the front-to-back direction. The folding cabinet also includes a fixing plate 4 arranged along the front-to-back direction. The fixing plate 4 is located within the storage space 103, and its front and rear side walls are detachably connected to the front panel 11 and the rear panel 12, respectively.

[0047] Understandably, when the enclosure structure 1 is in the unfolded state, the presence of the fixing plate 4 increases the front and rear support of the front plate 11 and the rear plate 12, reduces the probability of the folding cabinet swaying back and forth in the assembled state, and improves the stability of the folding cabinet in the assembled state.

[0048] As shown in Figure 13, the aforementioned fixing plate 4 is detached from the enclosure structure 1 and stored in the second space 102. In this way, the fixing plate 4 and the cabinet panel 2 can be stored simultaneously, and both the fixing plate 4 and the cabinet panel 2 can be stored in the enclosure structure 1, reducing the cumbersome storage of the additional fixing plate 4 and the space occupied, and facilitating transportation and packaging.

[0049] Furthermore, as shown in Figures 1-5 and Figure 14, the enclosure structure 1 also includes a front vertical beam 171 and a rear vertical beam 172 arranged sequentially from front to back. Both the front vertical beam 171 and the rear vertical beam 172 are arranged vertically. The front vertical beam 171 is connected to the front frame and is detachably connected to the front sidewall of the fixed plate 4. The rear vertical beam 172 is connected to the rear frame and is detachably connected to the rear sidewall of the fixed plate 4. Thus, the presence of the front vertical beam 171 and the rear vertical beam 172 improves the vertical support capacity of the cabinet panel 2, facilitates the assembly and disassembly of the fixed plate 4, and increases the strength of the front panel 11 and the rear panel 12. The upper and lower ends of the aforementioned front vertical beam 171 are respectively connected to two horizontal beams 162 located on the front side. The upper and lower ends of the rear vertical beam 172 are respectively connected to two horizontal beams 162 located on the rear side.

[0050] Specifically, as shown in Figures 1-5 and Figure 15, the cabinet panel 2 is provided with longitudinal beams 18 extending along the front-to-back direction. That is, both the top panel 200 and the bottom panel 201 are provided with longitudinal beams 18. The upper and lower side walls of the fixing plate 4 are detachably connected to the corresponding longitudinal beams 18. That is, the upper side wall of the fixing plate 4 is detachably connected to the upper longitudinal beam 18, and the lower side wall of the fixing plate 4 is detachably connected to the lower longitudinal beam 18. In this embodiment, the upper longitudinal beam 18 is fixed to the bottom surface of the top panel 200, and the lower longitudinal beam 18 is fixed to the outer bottom surface of the bottom panel 201.

[0051] It is understandable that the upper and lower side walls and the front and rear side walls of the fixing plate 4 are connected to the enclosure structure 1, thereby increasing the reliability of the installation of the fixing plate 4.

[0052] As shown in Figure 4, the fixed plate 4 divides the storage space 103 into a first cavity 1031 and a second cavity 1032 arranged sequentially along the left-right direction. At least one of the first cavity 1031 and the second cavity 1032 is equipped with a partition plate 5, and the left and right side walls of the partition plate 5 are detachably connected to the fixed plate 4 and the side plates 13, respectively. This provides support for the two side plates 13, increasing the stability of the folding cabinet after assembly; it also facilitates the user's classification and storage of items, better meeting different user needs. Furthermore, the position of the fixed plate 4 in the left-right direction can be selected according to actual needs.

[0053] In one embodiment, as an illustration, a partition plate 5 is provided in both the first cavity 1031 and the second cavity 1032. In other embodiments, a partition plate 5 is provided in either the first cavity 1031 or the second cavity 1032.

[0054] In this embodiment, as shown in Figures 2, 4, and 5, the partition plate 5 includes a first side edge 51 and a second side edge 52 arranged at intervals along the left-right direction. Specifically, in order to constrain the partition plate 5 to the fixed plate 4, the fixed plate 4 is provided with a locking member 41 that locks the partition plate 5 near the first side edge 51. The locking member 41 can be a screw, bolt, or clip. The side plate 13 is provided with a connecting frame 133 extending along the front-back direction at the position corresponding to the partition plate 5, and the second side edge 52 of the partition plate 5 is detachably connected to the connecting frame 133.

[0055] With the enclosure structure 1 folded, the partition 5 detaches from the enclosure structure 1 and is stored between the two side panels 13. A gap 104 is left between the two side panels 13 in the left-right direction, and the partition 5 is located within the gap 104. It is understood that when the enclosure structure 1 is folded, the partition 5 can be stored, reducing the inconvenience and space occupation associated with storing the partition 5, and facilitating transportation and packaging.

[0056] Furthermore, as shown in Figures 1, 2, 4, 7, and 8, the folding cabinet also includes support legs 6 for supporting the enclosure structure 1, which are disposed on the outer bottom surface of the base plate 201. In one embodiment, the support legs 6 are fixed to the outer bottom surface of the base plate 201. For ease of transportation and packaging, in this embodiment, the support legs 6 are detachably mounted on the outer bottom surface of the base plate 201. To prevent the support legs 6 from being lost, when the enclosure structure 1 is in the folded state, the support legs 6 detach from the base plate 201 and are stored between the two side panels 13.

[0057] To adjust the vertical height of the enclosure structure 1, the support leg 6 is mounted on the outer bottom surface of the base plate 201, allowing it to move vertically. There are several ways to achieve this vertical movement of the support leg 6. One method is to use a screw, where the support leg 6 is threadedly connected to the base plate 201, and only the screw needs to be rotated to adjust the height of the enclosure structure 1. Alternatively, a lifting mechanism can be used, where the support leg 6 is connected to the base plate 201 via a lifting mechanism, and the vertical movement of the lifting mechanism adjusts the height of the enclosure structure 1.

[0058] To improve the reliability of the support for the base plate 201, as shown in Figures 1, 2, 4, 7 and 8, there are four support legs 6, namely two front support legs 61 and two rear support legs 62. The two front support legs 61 are located on the front side and are arranged at intervals along the left and right directions, and the two rear support legs 62 are located on the rear side and are arranged at intervals along the left and right directions.

[0059] In this embodiment, the folding cabinet also includes two connecting beams 7 extending in the front-to-back direction, spaced apart in the left-to-right direction. The connection method between the two connecting beams 7 and the front support leg 61 and the rear support leg 62 is basically the same; the following description uses one of the connecting beams 7 as an example. At least a portion of the connecting beam 7 is located below the side panel 13, and the front end of the connecting beam 7 is detachably connected to the front support leg 61, and the rear end of the connecting beam 7 is detachably connected to the rear support leg 62.

[0060] Understandably, when the folding cabinet is in its assembled state, the presence of the connecting beam 7 improves the front and rear support of the front support leg 61 and the rear support leg 62. Furthermore, when the folding cabinet (i.e., the enclosure structure 1) is in its folded state, the connecting beam 7, the front support leg 61, and the rear support leg 62 can be disassembled for convenient transportation and packaging. When the enclosure structure 1 is in its folded state, the connecting beam 7, the front support leg 61, and the rear support leg 62 are all stored between the two side panels.

[0061] There are several ways to achieve the above-mentioned detachable connection. It can be achieved by using connectors such as screws or bolts, by using clips, or by using a combination of connectors and clips.

[0062] To prevent the assembled folding cabinet from wobbling back and forth, as shown in Figures 3, 7 and 8, the top wall of the connecting beam 7 and the bottom wall of the side plate 13 are provided with interlocking flanges 71 and limiting grooves 132. One of the flanges 71 and limiting grooves 132 is provided on the top wall of the connecting beam 7, and the other flange 71 and limiting groove 132 is provided on the bottom wall of the side plate 13.

[0063] In this embodiment, as shown in Figures 3, 7, and 8, the flange 71 is disposed on the top wall of the connecting beam 7, and the limiting groove 132 is located on the bottom wall of the side plate 13. Specifically, a limiting groove 132 is provided on the bottom wall of each side plate unit 131. Alternatively, a limiting groove 132 may be provided on the bottom wall of only one side plate unit 131.

[0064] In other embodiments, the flange 71 is provided on the bottom wall of the side plate 13, and the limiting groove 132 is provided on the top wall of the connecting beam 7. Specifically, a flange 71 is provided on the bottom wall of each side plate unit 131. Alternatively, a flange 71 may be provided on the bottom wall of only one side plate unit 131.
