Description

Technical Field

[0001] This invention relates to a container, and more particularly to a container and its side panels. Background Technology

[0002] For existing foldable containers, the maximum height of the side panels generally cannot exceed the length of the base minus the thickness of the side panels; otherwise, it will affect the folding of the side panels (they cannot be folded flat). When the length and width of the base are limited, the maximum height of the side panels is also limited accordingly. To increase the container's volume, it is generally necessary to keep the base's bottom surface unchanged and increase the base height to raise the container and thus increase its volume.

[0003] However, as the base height increases, the total height of the folded container also increases. These types of foldable containers are typically transported via containers or vans during recycling and transfer. The total height of the folded container determines the number that can be packed into the container or van. A higher total height folded means fewer containers can be packed, significantly increasing recycling and transportation costs. Simultaneously, in warehousing management, the total height of the folded container determines the number that can be stacked in the warehouse. A higher total height folded means fewer containers can be stacked in the warehouse, increasing not only warehousing costs but also indirectly raising the container's turnover cost.

[0004] In addition, increasing the height of the side panels can also increase the container's volume. However, the increased height of the side panels, when folded, exceeds the length and width of the base, necessitating folding the side panels in half before folding again. This method not only increases the number of steps and the difficulty of operation, but also, as the thickness of the side panels increases after folding, the base must be raised accordingly, further increasing the total height of the folded container and significantly reducing its recycling rate. Summary of the Invention

[0005] The purpose of this invention is to provide a container and its side panel, such that the upper part of the side panel is adjustable without increasing the thickness of the side panel.

[0071] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0072] One embodiment of the present invention relates to a side plate 101 of a container 100. For example... Figure 1 As shown, container 100 is a foldable container, including: a base 6, a pair of opposing first side plates and a pair of opposing second side plates 102. The first side plates 101 and second side plates 102 form a receiving space around the base 6, and the first side plates 101 and second side plates 102 are folded and connected to the base 6. The first side plate 101 can be the same as in this embodiment, so that when folded onto the base 6, the height of the first side plate 101 can be reduced, facilitating folding. In other embodiments, the second side plate 102 of container 100 can also be the same as in this example.

[0073] like Figure 1 and Figure 2 As shown, the side panel 101 of the container 100 includes: a first plate 2, a second plate 3, a limiting member 4, and a locking member 5. The second plate 3 and the first plate 2 are arranged along the height direction of the side panel 101. The second plate 3 has a main plate 31 and an extension plate 32 fixedly connected to the main plate 31. The extension plate 32 is slidably connected to the first plate 2 along the height direction of the side panel 101. The limiting member 4 passes through the extension plate 32 and is fixedly connected to the extension plate 32, and the limiting member 4 is slidably connected to the first plate 2 along the height direction of the side panel 101. Figure 3 and Figure 4As shown, the locking fastener 5 is installed on the first plate 2. When locked, the locking fastener 5 is used to position the limiting member 4 in the first position, making the side plate 101 a high plate; as Figure 5 and Figure 6 As shown, the locking element 5 is used to release the limiting element 4 after being triggered, causing the limiting element 4 to slide downwards along the first plate 2 to the second position, reducing the height of the side plate 101 to form a short plate. Pulling the main plate upwards causes the main plate to slide the extension plate 32 upwards along the first plate 2, and the limiting element 4 is also moved upwards by the extension rod. When the limiting element 4 slides to the first position, the locking element 5 locks the limiting element 4, limiting and positioning it. At the same time, the extension plate 32 and the main plate are also positioned, and the side plate 101 forms a tall plate. Triggering the locking element 5 releases the limiting element 4, causing it to slide down to the second position. At the same time, the extension plate 32 and the main plate are also moved down, reducing the height of the side plate 101, making the side plate 101 a short plate.

[0074] The side panel 101 is fixed to the extension plate 32 by the limiting member 4, with the limiting member 4 in the first position. The locking member 5 limits the limiting member 4, and the side panel 101 is a high plate. When the side panel 101 is a low plate, the locking member 5 is triggered to release the limiting member 4 and lower it, and the extension plate 32 also lowers, reducing the height of the side panel 101. When the side panel 101 forms both high and low plate shapes, the side panel 101 does not need to be folded, nor does it increase the thickness of the side panel 101.

[0075] Furthermore, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the locking element 5 includes a latch 51, a reset element 52, and a drive element 53. The latch 51 is rotatably connected to the first plate 2. The two ends of the reset element 52 abut against the latch 51 and the first plate 2 respectively, and the reset element 52 provides a thrust for the latch 51 to rotate below the limiting element 4. The drive element 53 is connected to the latch 51, and the drive element 53 is used to drive the latch 51 to rotate around its hinge point with the first plate 2, and the latch 51 rotates to a preset position where the latch 51 is offset from below the limiting element 4.

[0076] Specifically, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the bottom side plate 101 of the latch 51 has a rotating shaft 54 ​​that is rotatably connected to the first plate 2. The reset member 52 is a spring that is inserted into the slot of the latch 51. One end of the spring abuts against the latch 51, and the other end abuts against the inner wall of the first plate 2. The top of the latch 51 has a recess 511 on the side facing the limiting member 4. When the latch 51 is in the free state, the reset member 52 pushes the latch 51 to rotate around the rotating shaft 54. The top of the latch 51 rotates to below the limiting member 4. The bottom surface and side wall of the recess 511 abut against the limiting member 4. That is, part of the latch 51 is located on the extension line of the limiting member 4, and the bottom of the limiting member 4 is located in the recess 511, receiving the limiting member 4. Thus, the limiting member 4 will not descend further, keeping the side plate 101 in a high plate state. When the side plate 101 is in the high plate state, the driving member 53 drives the locking tongue 51 to rotate in the opposite direction, and the locking tongue 51 moves away from the bottom of the limiting member 4. At this time, the limiting member 4 is not directly supported by the locking tongue 51. The limiting member 4 slides down to be supported by the bottom of the first plate 2. The limiting member 4 lowers the second plate 3, so that the height of the side plate 101 is reduced to form a low plate state. At this time, the limiting member 4 is located on the side of the locking tongue 51, that is, the limiting member 4 is adjacent to the side wall 512 of the locking tongue 51 facing the limiting member 4. As shown in the figure, the limiting member 4 is located on the left side of the locking tongue 51. The limiting member 51 prevents the locking tongue 51 from being driven to rotate back to the original free state by the reset member 52, and prevents the locking tongue 51 from being partially in the area below the limiting member 4. To restore the lock tongue from its low-profile state to its high-profile state, the first plate 2 can be lifted, causing the main plate to lift the extension plate 32. The extension plate 32 then lifts the limiting member 4. The limiting member 4 is not located next to the side wall 512 of the latch 51, as shown in the figure. The limiting member 4 is not to the left of the side wall 512 of the latch 51. The reset member 52 pushes the latch 51 to rotate back to its original position, meaning that part of the latch 51 is located below the limiting member 4 on the extension line. At this time, the limiting member 4 no longer limits the latch 51. The latch 51 is driven by the reset member 52 to rotate back to its original position, supporting the limiting member 4 and causing the limiting member 4 to be lifted up. The side plate 101 is now a high plate.

[0077] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the latch 51 has an inclined sliding cavity 510, and the drive member 53 has a sliding portion 530 that is embedded in and slides along the sliding cavity 510. The drive member 53 moves along the height direction of the side plate 101, and the sliding portion 530 slides along the sliding cavity 510 to drive the latch 51 to rotate below or away from the limit member 4.

[0078] The locking tongue structure is not limited to the structure described above; there is another structure, such as... Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, Figure 9 and Figure 10The structure when the first side plate is a high plate, for another type of locking mechanism. Figure 11 and Figure 12 In another locking mechanism where the first side plate is a low plate, the top of the side wall of the latch 501 is hinged to the first plate body, and the bottom of the latch 501 abuts against the first plate body 2. The reset member 504 abuts against the surfaces of the latch 501 and the first plate body 2 extending along the height direction of the side plate. The rotation axis 505 of the latch 501 is located in the top region of the side of the latch 501. The sliding cavity 502 is located in the middle region of the latch 501 and extends obliquely. The sliding part 506 is embedded in the sliding cavity 502 and slides along the sliding cavity 502. The top region of the latch 501 has a recess 503 for supporting the limiting member. The recess 503 and the rotation axis 505 are located on both sides of the latch 501. When the latch 501 supports the limiting member, the bottom of the latch 501 abuts against the horizontal plate of the first plate body 2. When the locking tongue 501 moves away from below the limiting member, the bottom of the locking tongue 501 moves along the first plate 2, and the part of the locking tongue 501 protruding below the limiting member moves to above the first plate 2.

[0079] Furthermore, such as Figure 5 and Figure 6 As shown, the driving member 53 slides downward, the sliding part 530 slides along the sliding cavity part 510, the sliding part 530 pushes against the side wall of the sliding cavity, the driving bolt 51 deviates from below the limiting member 4, and the limiting member 4 slides downward to the second position. Figure 3 and Figure 4 As shown, when the limiting member 4 is pulled up to the first position, the resetting member 52 pushes the locking tongue 51, causing the sliding part 530 to slide along the sliding cavity 510. The driving member 53 slides upward, and the locking tongue 51 moves to below the limiting member 4 and abuts against the limiting member 4. The driving member 53 can be a pedal; by stepping on the pedal downward, the sliding part 530 slides along the sliding cavity 510, driving the locking tongue 51 to rotate and deviate from below the limiting member 4. Figure 7 and Figure 8 As shown, a portion of the driving component 53 is inserted into the first plate 2, and is bent to form a limiting protrusion 531 that hooks the first plate 2. When the driving component 53 slides up and down, the limiting protrusion slides up and down along the first plate 2, so that the driving component 53 will not fall off and can also slide up and down along the first plate 2.

[0080] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when the second plate 3 is pulled, the limiting member 4 slides upward away from the side wall 512 of the latch 51, thus not occupying the space on the side of the latch 51, allowing the latch 51 to rotate below the limiting member 4 when pushed by the reset member 52. In this embodiment, the driving member 53 is stepped down, causing the latch 51 to deviate from below the limiting member 4. In other embodiments, the driving member 53 may move upward, deviating from below the limiting member 4.

[0081] Furthermore, such as Figure 13 and Figure 14 As shown, the limiting member can be a rod or a plate. The limiting member 4 includes a limiting member body 41 and a pair of plugs 42 that seal both ends of the limiting member body 41. When the top of the limiting member 4 abuts against the main plate, the contact area is larger and the stability is better. When the bottom of the limiting member 4 contacts the first plate 2 and the locking tongue 51, the contact area is also larger and the stability is better.

[0082] In addition, such as Figure 13 and Figure 14 As shown, the main body plate 31 has a first stop portion 311 that abuts against the limiting member 4. Specifically, the first stop portion 311 may be a horizontal plate extending horizontally within the main body plate 31.

[0083] Furthermore, such as Figure 13 and Figure 14 , Figure 15 As shown, the extension plate 32 has a raised portion 321 that is slidably connected to the first plate 2 and an insertion portion 322 connected to the raised portion 321. The insertion portion 322 is inserted into the main plate 31. The insertion portion 322 is fixed to the main plate 31 and the limiting member 4.

[0084] Furthermore, such as Figure 13 and Figure 14 As shown, the insertion part 322 is snapped into connection with the limiting member 4 and the main body plate 31. In this embodiment, the insertion part 322 has a protruding first protrusion 323, and the limiting member 4 has a snap-fit ​​groove 43, with the protrusion engaging in the snap-fit ​​contact. Furthermore, the bottom surface of the first protrusion 323 is an upwardly sloping surface, which facilitates the assembly and snap-fit ​​of the extension plate 32 and the limiting member 4 together. Figure 13 and Figure 15 As shown, the insertion part 322 is engaged with the main body plate 31. The insertion part 322 has a protruding second protrusion 324, and the main body plate 31 has a hole. During assembly, the insertion part 322 is inserted into the main body plate 31, allowing the second protrusion 324 to embed into the hole, thereby achieving the positioning and fixation of the extension plate 32 and the main body plate 31. In other embodiments, there are various ways in which the insertion part 322 engages with the limiting member 4 and the main body plate 31, which will not be described in detail here.

[0085] Specifically, in this embodiment, to ensure that the heightened portion 321 is slidably connected to the first plate 2 while also making the resulting side plate 101 more robust and stable, the heightened portion 321 is nested within the first plate 2. That is, the heightened portion and the first plate 2 mutually abut and limit each other in the thickness, width, and height directions. Figure 20 and Figure 21As shown, the first plate 2 has a first layer plate 21 and a first bent plate 22 bent and connected to the first layer plate 21. The heightened part 321 has a second layer plate 9 and a second bent plate 7 bent and connected to the second layer plate 9. The first layer plate 21 and the second layer plate 9 are disposed opposite to each other; the first layer plate 21 and the first bent plate 22 cooperate to limit the second bent plate 7, and an adjacent pair of first bent plates 22 cooperate to limit the second bent plate 7; the second layer plate 9 and the second bent plate 7 cooperate to limit the first bent plate 22, and an adjacent pair of second bent plates 7 cooperate to limit the first bent plate 22. As shown in the figure, a plurality of first bent plates 22 are connected to the first layer plate 21. Each first bent plate 22 includes: a first connecting plate 221 perpendicularly connected to the first layer plate 21; two first extension plates 222 extending from one end of the first connecting plate 221; a first vertical plate 223 with one end of each first extension plate 222 bent; and a first short plate 224 extending from one end of the first vertical plate 223. The first vertical plate 223 is parallel to the first connecting plate 221, and the first extension plate 222 and the first short plate 224 are parallel to the first layer plate 21. The structure of the first plate 2 is similar to that of the heightened section 321. Multiple second bent plates 7 are connected to the second layer plate 9. Each second bent plate 7 includes: a second connecting plate 71 perpendicularly connected to the second layer plate 9; two second extension plates 72 extending from one end of the second connecting plate 71; a second vertical plate 73 with one end of each second extension plate 72 bent; and a second short plate 74 extending from one end of each second vertical plate 73. The second vertical plate 73 is parallel to the second connecting plate 71, and the second extension plates 72 and second short plates 74 are parallel to the second layer plate 9. The second connecting plate 71 is sandwiched between the first vertical plates 223 of two different first bent plates 22, and the second extension plates 72 are sandwiched between the first layer plate 21 and the first short plate 224. The first connecting plate 221 is sandwiched between the second vertical plates 73 of two different second bent plates 7, and the first extension plates 222 are sandwiched between the second layer plate 9 and the second short plate 74.

[0086] Furthermore, such as Figure 2 As shown, the side plate 101 also includes a reinforcing rod 8 inserted into the first plate 2 and the extension plate 32.

[0087] Furthermore, such as Figure 17 , Figure 18 and Figure 19 As shown, the reinforcing rod 8 includes: a reinforcing rod body 81, and a pair of limiting shafts 82, each connected to the reinforcing rod body 81. One of the limiting shafts 82 is inserted into the first plate 2, and the other is inserted into the extension plate 32.

[0088] Furthermore, such as Figure 17 and Figure 19 As shown, a limiting shaft 82 abuts against the side of the top surface of the raised part 321 that is away from the first plate 2.

[0089] In addition, such as Figure 17 , Figure 18 and Figure 19 As shown, the limiting shaft 82 is movably connected to the reinforcing rod body 81. The limiting shaft 82 has a spring piece 821 inserted into the reinforcing rod body 81, and a pair of shafts 822 connected to the spring piece 821 and extending out of the reinforcing rod body 81. The spring piece 821 provides a thrust to the pair of shafts 822, causing the pair of shafts 822 to separate from each other. This facilitates the installation of the limiting shaft 82 in the body of the reinforcing rod 8. When the reinforcing rod 8 is installed on the first plate 2 and the second plate 3, the shafts 822 can be moved closer to the interior of the reinforcing rod body 81 during installation. This prevents the reinforcing rod 8 from being inconveniently installed in the first plate 2 and the second plate 3 due to the protrusion of the shafts 822, and the spring piece 821 can push the shafts 822 to be firmly fixed on the reinforcing rod 8. The number of reinforcing rods 8 can be one or more.

[0090] In addition, such as Figure 1 As shown, there is a pair of limiting members 4, which are spaced apart along the width direction of the side plate 101. There is a pair of locking members 5, which are provided in a one-to-one correspondence with the limiting members 4.

[0091] Another embodiment of the invention relates to a container. For example... Figure 1 As shown, the container is a foldable container, including: a base 6, a pair of opposing first side panels 101 and a pair of opposing second side panels 102. The pair of first side panels 101 and the pair of second side panels 102 surround the base to form a receiving space, and the first side panels 101 and the second side panels 102 are folded and connected to the base 6. At least one of the pair of first side panels 101 and the pair of second side panels 102 is a side panel as described in the above example.
