[0004] There are a variety of objects that can be transported or stored in such containers. There is a demand for containers that are more versatile and can accommodate a wide variety of objects with irregular shapes. Specifically, there is a demand for containers that can flexibly accommodate the fastening, transporting, and storing of objects with different shapes, structures, and / or fastening methods.

[0005] In order to accommodate a wide variety of irregularly shaped objects, one method is to use a prefabricated container that allows the layout of supports, beams, etc. to be changed. If the container has a frame and supports, it may be possible to accommodate different types of objects by changing the mounting position and number of the supports relative to the frame. Therefore, another demand is for a prefabricated container whose layout can be easily changed.

[Figure 9] FIG. 10 is a perspective view of a third embodiment of a container of the present disclosure. [Figure 10A] FIG. [Figure 10B] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a first embodiment of a container according to the present disclosure. The collapsible container 100 can be used to transport panel-like objects in a leaning position. The panel-like objects may be, for example, painted steel plates or large display panels. The container 100 can also be used to transport multiple objects without them touching each other.

[0013] The container 100 is composed of a bottom plate 10, which is the lower frame, four support columns 12 installed (standing) in the Z-axis direction from the four corners of the bottom plate 10, and a total of four beam members 14, 14, 18, 18 spanning between each two of the four support columns. The beam members 14 are arranged along the X-axis direction, and the beam members 18 are arranged along the Y-axis direction. The support columns 12 are formed by bending flat members of the same shape cut out from steel plate, and then assembling and fastening them together. Figure 2 is an explanatory diagram showing the cutting and assembly method.

[0014] A method for assembling the support 12 will be described with reference to Figure 2. First, two plates 2 and 3 are cut out from the steel plate 1 according to a design drawing on the steel plate 1 (the design drawing does not need to be drawn in reality, and is shown for ease of explanation). The two plates 2 and 3 have a shape obtained by dividing the development view of the support 12 into two. For ease of understanding, the plates 2 and 3 are drawn in different directions, but in reality, when cut out from the steel plate 1, the plates 2 and 3 have no front and back and may have the same shape.

[0015] It is also possible to use the development drawing of the support 12 as the design drawing, cut out one plate according to it, and bend it to form the support 12. It is also possible to use a process of cutting out three or more plate pieces, bending them, and fastening them together to form the support 12. On the other hand, if a design drawing is used in which the development drawing of the support 12 is divided into two parts with the same shape, as shown in Figure 2, all of the processes from preparing the design drawing, cutting, and assembling can be simplified.

[0016] The cut-out plates 2 and 3 are then bent at predetermined edges (FIG. 2C). Plates 2 and 3 have faces 2A and 3A, respectively, which form the end faces of support 12. Furthermore, ears 2B and 3B extend from faces 2A and 3A. When combining (FIG. 2D), facing plates 2 and 3 are fastened to each other (without welding) by passing fastening members (bolts, rivets, etc.) from the outside of plates 2 and 3 toward ears 2B and 3B, and support 12 can be formed.

[0017] The support 12 assembled in this manner has a plurality of through holes 12A on each side. These through holes 12A can be used to fasten the bottom plate 10, beam members 14, 18, and other components. The support 12 has a plurality of through holes 12A at predetermined intervals throughout its entire length. These intervals may be equal or random. By providing a plurality of through holes 12A at equal or random intervals, the fastening positions of various components can be changed as desired. Therefore, the container 100 can adopt various layouts other than those shown in the drawings, depending on the shape of the object, etc.

[0018] Returning to FIG. 1 , beam member 14 is bridged between support columns 12 along the X-axis direction. In addition, in the height direction, the longitudinal direction of beam member 14 is parallel to bottom plate 10. Beam member 18 is bridged between support columns 12 along the Y-axis direction. Therefore, beam member 14 and beam member 18 are perpendicular to each other in a plan view.

[0019] The beam members 14 are provided so as to face two of the four support columns 12, respectively. The two beam members 14 are parallel in a plan view. On the other hand, the two beam members 18 are arranged side by side in the Z-axis direction (up and down direction) between any two of the four support columns 12. The two beam members 18 appear to overlap in a plan view. With this configuration, the beam members 14, 14, 18 form a U-shape with an opening in a plan view. The direction of this opening is the direction in which objects are carried in and out.

[0020] The beam members 14, 18, like the support column 12, are cut out from steel plate and formed by bending. Although not shown, the beam members 14, 18 are formed in a channel shape (groove shape) as a whole. In other words, they are U-shaped in cross section. Therefore, they can be formed through a process of cutting out the members from steel plate based on a design drawing, which is the development drawing itself, and a process of bending the cut members into the desired shape. No assembly process is required. The cut beam members 14, 18 are fixed to the support column 12. At that time, the beam members 14, 18 can be fixed in the desired position by using the through-holes 12A.

[0021] The container 100 includes a plurality of partition members 16. Each partition member 16 is formed as a U-shaped frame. The ends of the partition members 16 on the open side of the U-shape are fixed to two beam members 18 arranged parallel to the Z-axis direction.

[0022] The partition member 16 is also formed in a channel shape similar to the beam members 14, 18. Therefore, it is formed into the desired shape by bending a member cut out from a steel plate. In FIG. 1, the partition member 16 is covered with a sheet, which prevents damage to the object leaned against it.

[0023] The U-shaped curve of the partition member 16 is formed by utilizing a wedge-shaped notch that is previously provided in a plate-like member. Figure 3 is an enlarged view of the U-shaped curve of the partition member 16. For ease of explanation, Figure 3 shows a state in which the cover sheet shown in Figure 1 has been removed.

[0024] Here, the partition member 16 can be broadly divided into a straight portion 16A, a curved portion 16B, and a straight portion 16C. A plurality of slits 16D are provided in the curved portion 16B. These slits 16D are formed as wedge-shaped notches when the member is cut out from a flat steel plate. When cutting out the flat steel plate, a plurality of wedge-shaped notches are formed in advance in the part that will become the inside of the curved portion 16B, extending from the outer edge on one side to the outer edge on the opposite side. By bending this, as shown in Figure 3, the difference in distance between the inside and outside of the curved portion 16B can be absorbed, forming a neat curve. The number of slits 16D can be adjusted appropriately depending on the curvature.

[0025] Returning to FIG. 1 , the beam member 18 is provided with a plurality of receiving grooves 20 into which the partition member 16 is fitted and fixed. The receiving grooves 20 are provided at corresponding locations on the upper and lower beam members 18. In other words, a pair of receiving grooves 20 is provided at positions that overlap in a plan view. The partition member 16 is fixed with both ends thereof fitted into the pair of receiving grooves 20.

[0026] One of the features of the container 100 of this example is that the beam members 18 are provided with second receiving grooves 22. In the example shown in FIG. 1 , the second receiving grooves 22 are not used to secure the partition members 16. The second receiving grooves 22 have the same shape as the receiving grooves 20 and are provided at corresponding positions on the upper and lower beam members 18, and thus function identically to the receiving grooves 20. The second receiving grooves 22 are provided for the purpose of flexibly changing the position and number of the partition members 16 depending on the object. In the drawing, two second receiving grooves 22 are provided per beam member 18, but the number is not limited to this. More second receiving grooves 22 may be provided on the beam members 18. Furthermore, the spacing between the second receiving grooves 22 and the spacing between the receiving grooves 20 and the second receiving grooves 22 may be uniform or random.

[0027] Next, a method for replacing the partition member 16 between the receiving groove 20 and the second receiving groove 22 will be described. The replacement operation is performed, for example, when the type of object to be transported by the container 100 is changed. FIG. 4 is an enlarged view of a portion AA in FIG. 1. As shown in FIG. 4, a butterfly bolt 16E (first screw member) is arranged at the end of the partition member 16. The butterfly bolt 16E is screwed into a through-hole (not shown) formed in the end surface (bottom surface of the end) of the partition member 16.

[0028] The receiving groove 20 and the second receiving groove 22 have the same shape. The receiving groove 20 is shaped so that it can receive and fit the end of the partition member 16 from above. The receiving groove 20 also has a notched screw locking portion 16F at its tip that receives the shank of the butterfly bolt 16E. The screw locking portion 16F is provided on the side surface of the beam member 18 from the upper surface to a position halfway up the height direction. The width of the screw locking portion 16F is set to a width that can receive the shank of the butterfly bolt 16E with minimal play.

[0029] With this configuration, when the partition member 16 is fitted into the receiving groove 20 from above the beam member 18, the shaft portion of the butterfly bolt 16E is caught in the screw-locking portion 16F. This allows the beam member 18 to be supported by the receiving groove 20. At this time, the head of the butterfly bolt 16E protrudes from the side of the beam member 18. This is because the shaft portion of the butterfly bolt 16E is caught in the screw-locking portion 16F. When the butterfly bolt 16E is tightened in this state, the beam member 18 and the partition member 16 are fastened and fixed via the screw-locking portion 16F. The second receiving groove 22 has the same shape as the receiving groove 20, and therefore has the same function and method of use. The butterfly bolt 16E is an example of a hand-turnable bolt, and the specific shape of the first screw member is not limited to a butterfly bolt. Needless to say, bolts that require tools for tightening and loosening can also be used.

[0030] The procedure for moving the partition member 16 from the receiving groove 20 to the second receiving groove 22 is as follows. First, loosen the tightened wing bolt 16E. Because the wing bolt 16E is used, no tools are required for tightening or loosening. After releasing the partition member 16, the user lifts the partition member 16 in the direction of arrow M1 and removes the end of the partition member 16 from the receiving groove 20. Next, the user moves the partition member 16 in the direction of arrow M2 and fits the end into the second receiving groove 22. Finally, the user tightens the wing bolt 16E by hand. The user performs this procedure on both ends of the partition member 16. The partition member 16 is now moved from the receiving groove 20 to the second receiving groove 22.

[0031] This series of operations has two main advantages. One is that no tools are required to move the partition member 16 between the receiving grooves. The other is that the butterfly bolt 16E does not need to be completely removed when moving the partition member 16 between the receiving grooves. In the prior art, the partition member 16 is bolted through a through-hole in the beam member 18. In this case, the bolts must be removed to move the partition member 16 between the receiving grooves. Needless to say, tools are required to remove the bolts. Furthermore, problems such as the loss of the removed bolts and their inclusion in the target object can occur. A removed and lost bolt could cause a defect in the target object. Therefore, if a bolt is lost during a transport operation, the user may be required to search for it. The user's search for the bolt can be one of the factors that delay the entire work process.

[0032] The container 100 of this example has multiple second receiving grooves 22, ensuring flexibility to instantly accommodate objects of various shapes, numbers, and structures. Furthermore, when moving the partition member 16 between receiving grooves, there is no need to remove the member used to secure it (first screw member: in this case, butterfly bolt 16E), so it cannot be lost. Furthermore, the partition member 16 can be moved between receiving grooves quickly and without tools.

[0033] FIG. 5 is a perspective view of a second embodiment of a container according to the present disclosure. The container 200 has a function suitable for placing or securing a wide variety of objects, such as exterior materials for machinery, and / or objects of irregular shapes for transport. For example, the container 200 is particularly suitable for transporting painted objects or for loading heavy objects onto the container 200 using a forklift. This is because the container 200 allows the object to be placed on the container 200 without the bottom surface of the object coming into contact with the container 200. Furthermore, the container 200 allows the object to be securely secured to the container 200 to prevent damage caused by tipping or sliding during transport. Furthermore, the container 200 can be used for a wide variety of objects, structures, and / or sizes.

[0034] The container 200 is composed of a bottom plate 10, which is a lower frame; four support columns 12 installed in the Z-axis direction from the four corners of the bottom plate 10; two intermediate support columns 34 installed in the Y-axis direction on the side edges of the lower frame between a pair of support columns 12 lined up in the Y-axis direction; and multiple beam members. Legs 38 for installation are attached to the lower ends of the support columns 12. The beam member 30 is bridged between two adjacent support columns 12 along the X-axis direction. Multiple through holes 30A are formed in the surface of the beam member 30. The function of the through holes 30A will be described later.

[0035] The beam member 30 is spanned between two sets of one of the four columns 12. A different beam structure is formed on the other set of columns 12 between which the beam member 30 is not spanned. This different beam structure is composed of two beam members 36 extending in the Y-axis direction and a beam member 32 extending in the X-axis direction and spanned between two of the opposing beam members 36. The two beam members 36 and the beam member 32 form the shape of the letter H in plan view.

[0036] One end of beam member 36 is fixed to support column 12, and the other end is fixed to intermediate support column 34. The fixed position of beam member 36 is adjusted so that it is parallel to the surface of bottom plate 10. On the other hand, beam member 32 has locking structures 32B on both ends thereof, and is hooked onto beam member 36 and supported so as to be slidable. In other words, beam member 32 is not fixed to beam member 36. Like beam member 30, beam member 32 has a plurality of through holes 32A on its upper surface side.

[0037] Next, a method of using the container 200 will be described. FIG. 6 is a perspective view of the container 200 with an object 202 fixed thereto. The object 202, which is an exterior material of a machine, is fixed to the beam members 30 and 32 with one end placed on the beam member 30 and the other end placed on the beam member 32. A plurality of through holes are formed in the flanges at both ends of the object 202. Fixing bolts 30C and 32C are passed through the through holes and into the through holes 30A and 32A of the beam member 30 and 32, respectively. The through holes 30A and 32A are part of the female thread portion 28, which will be described later. The female thread portion 28 provides a female thread for the fixing bolts 30C and 32C inserted through the through holes 30A and 32A, respectively, and fixes the object 202. With this fixing method, a fork arm can be inserted because there is space on the bottom side of the object 202. Furthermore, since the contact points between the object 202 and the container 200 are minimized, even if the object 202 has been painted, the effect on the painted surface is minimized.

[0038] In this example, the object 202 is fixed by five fixing bolts 30C, 32C on each side. However, the required number of fixing bolts can be changed as appropriate depending on the shape and structure of the object. At least one fixing bolt needs to be used on the beam member 30 side and one on the beam member 32 side. The beam members 30, 32 are provided with through holes 30A, 32A at positions corresponding to each other, i.e., at positions that overlap when viewed from the Y-axis direction. This is called a set of through holes. The beam members 30, 32 are provided with multiple sets of through holes. Therefore, even if the shapes and structures of the objects are different, the set of through holes to be used can be flexibly selected and fixed.

[0039] Furthermore, the container 200 can accommodate objects of different sizes and lengths. As described above, the beam member 32 can slide freely in the Y-axis direction within the length of the beam member 36 spanning between the support column 12 and the intermediate support column 34. This allows the beam member 32 to be moved according to the length of the object, and it is also possible to add beam members 32 as needed. The container 200 can easily secure a wide variety of and / or irregularly shaped objects by using the female thread portion 28 including the multiple through holes 30A, 32A provided in the beam members 30, 32, and the beam member 32 with a sliding function.

[0040] When container 200 is used repeatedly, particularly when heavy object 202 is repeatedly attached and detached, the threads of female screw portion 28 may deteriorate and become stripped over time, making it difficult to attach and detach fixing bolts 30C, 32C. If the threads are stripped, one method is to replace beam members 30, 32 together. Since beam member 30 is simply fixed to through-hole 12A of 12 with a bolt, and beam member 32 is simply engaged with beam member 36, replacement itself is easy.

[0041] On the other hand, replacing the entire beam members 30, 32 is expensive and may result in downtime due to the lack of readily available replacement beam members 30, 32. The container 200 of this example solves this problem by using the female thread 28 mechanism.

[0042] 7 is an enlarged perspective view of the beam member 30, part BB in FIG. 5. No threads are provided on the inner wall surface of the through hole 30A of the beam member 30. The through hole 30A is merely for passing the fixing bolt 30C with a predetermined amount of play, and does not have a screw fastening function. In other words, the through hole 30A does not have a thread. The threads are provided by a nut 30D fixed from the back side of the through hole 30A. The nut 30D is fixed to the back side of the beam member 30 by a nut positioning member. The through hole 30A, the nut 30D, and the positioning member form the female thread portion 28.

[0043] 8 is an exploded view of the nut 30D and its positioning member disposed inside the beam member 30. The positioning member includes a positioning plate 42 and a fixing housing 44. The positioning plate 42 has through holes 42A in the number corresponding to the fixed number of through holes 30A in the beam member 30, and at corresponding locations. The through holes 42A are shaped so that the nut 30D does not rotate when fitted into them. In this example, the through holes 42A are formed as regular hexagonal holes that can accommodate the nut 30D, which has a regular hexagonal outer shape, with minimal play.

[0044] The nut 30D and its positioning member are stacked on top of each other in the following order from the back surface of the beam member 30: nut 30D, positioning plate 42, and fixing housing 44. In this state, the positioning member is fixed with fixing bolts 30C and fixing nuts 44D. The fixing bolts 30C are inserted through through holes 44E provided in the beam member 30 and through holes 44B in flange portions 44A provided on both ends of the fixing housing 44. The fixing nuts 44D are attached from the back surface of the flange portions 44A.

[0045] When the positioning member is fixed to the beam member 30, the through hole 30A, the nut 30D, the through hole 42A, and the through hole 44F are aligned along the Z axis. The through hole 44F is provided in the fixing housing 44. The inner diameter of the through hole 44F is smaller than the outer diameter of the nut 30D and is approximately the same as the inner diameter of the through hole 30A. The nut 30D itself is not fixed to the beam member 30. However, the nut 30D's rotation and sliding movement in the XY plane are restricted by the positioning plate 42. Furthermore, the positioning plate 42's sliding movement in the XY plane and the Z axis direction is restricted by the fixing housing 44 fixed to the back surface of the beam member 30. As a result, the nut 30D's rotation, sliding movement in the XY plane, and movement in the Z axis direction are restricted, and the nut 30D is indirectly fixed to the beam member 30, and its internal thread can be used to fix the object 202.

[0046] The advantage of the female thread portion 28 is that the thread originates from the nut 30D. Even if the thread deteriorates and becomes crushed, repair is possible by simply replacing the nut 30D, which is a standard product. Because the nut 30D is a standard product, a replacement can be easily procured, and the replacement work can be completed instantly by workers at the delivery site. Therefore, compared to replacing the entire beam member 30, it is significantly more cost-effective and time-efficient. Note that while the female thread portion 28 of the beam member 30 has been described here, the beam member 32 also has a similar female thread portion 28.

[0047] 9 is a perspective view of a third embodiment of a container according to the present disclosure. The container 300 is a cart equipped with a top plate 50, which is an upper frame. Specifically, the container 300 is composed of a bottom plate 10, support columns 12 installed upright at the four corners of the bottom plate 10, and the top plate 50 fixed to the upper ends of the support columns 12. Furthermore, the bottom plate 10 is provided with casters 26, and further, a grip portion 52 is provided on the upper portion of the support column 12. The grip portion 52 is formed by bending a metal plate member and is covered with a film. A user can grasp the grip portion 52 to push or pull the container 300, which is a cart.

[0048] There is no limitation on the object to be transported by container 300, but an example of the transported object (object) in this example is a pallet 302 that can be loaded and unloaded by a forklift. Pallet 302 has fork pockets 302A and 302B on its side. In reality, further objects to be transported may be placed or fixed on pallet 302, but this is not shown in the figure.

[0049] When loading and unloading this pallet 302 with a forklift, there is a desire to be able to insert the fork arms into the fork pockets 302A, 302B from any of the four sides of the container 300. In this example, the container 300 has the gripping parts 52 for transportation located at the rear, so in the state shown in Figure 9, it is not possible to insert the fork arms from the direction of the gripping parts 52. Or, even if the fork arms could be inserted, they would get caught on the gripping parts 52, making it impossible to load and unload the pallet 302.

[0050] In this case, one method is to remove the gripping part 52 when it is not needed. However, it is cumbersome to attach and detach the gripping part 52 each time it is transported, and there is also a risk that the bolts that secure the gripping part 52 to the through-holes 12A of the support posts 12 may be removed and lost. Therefore, the container 300 of this example is provided with a storage mechanism that can store the gripping part 52 without using tools or removing the bolts.

[0051] 10A is an enlarged view of the storage mechanism, portion CC in FIG. 9, and FIG. 10B is an enlarged view of the storage mechanism while gripper 52 is being stored. The storage mechanism is composed of two butterfly bolts 54A and 54B aligned vertically along the Z axis, and a locking hook 52A and a long through-hole 52B provided at the end of gripper 52. When gripper 52 is in use, butterfly bolts 54A and 54B are screwed into the end of locking hook 52A and the long through-hole 52B, respectively, thereby fixing gripper 52.

[0052] On the other hand, when storing the lid, as shown in FIG. 10B, the butterfly bolts 54A, 54B are loosened to release the engagement between the locking hook 52A and the butterfly bolt 54A. Specifically, the gripping portion 52 is lifted up within the range of the elongated through hole 52B, thereby disengaging the butterfly bolt 54A from the hook-shaped locking hook 52A. The width of the elongated through hole 52B is such that the shaft portion of the butterfly bolt 54B can pass through with minimal play. On the other hand, the length of the elongated through hole 52B is formed to allow the shaft portion of the butterfly bolt 54B to slide. "Within the range of the elongated through hole 52B" means within this range of sliding movement.

[0053] This configuration allows the gripping portion 52 to be easily stored without tools or bolt removal. Another advantage is that the risk of the user's fingers getting pinched when storing the gripping portion 52 is reduced. When storing the gripping portion 52, the butterfly bolts 54A and 54B are first loosened, but this alone does not cause the gripping portion 52 to fall. If the gripping portion 52 were configured to fall simply by loosening the butterfly bolts 54A and 54B, the gripping portion 52 could fall unexpectedly during storage, potentially causing injury to the user's fingers by pinching them. In the container 300, after loosening the butterfly bolts 54A and 54B, the gripping portion 52 is lifted up within the range of sliding movement of the elongated through-hole 52B. This is the first time the butterfly bolts 54A are released from the locking hook 52A and the gripping portion 52 can rotate. At this time, the user's hands are usually on the gripping portion 52, preventing them from getting pinched by the moving parts. Another advantage is that gripper 52 can be stored by simply loosening butterfly bolts 54A and 54B, without the need to remove them. By storing gripper 52, the fork arm can be easily inserted from the gripper 52 side as well. [Explanation of symbols]
