Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the container according to the present invention can be used not only as a marine container (intermodal container), but also as a truck box or a railway freight car, and can also be used as a container house. Therefore, in the specification and claims of this application, the term "container" includes marine containers, packing boxes, freight cars, and container houses. FIG. 1 is a perspective view showing a rough configuration of a container according to a first embodiment of the present invention.

The container 10 of the first embodiment includes a pair of left and right sides 12, a pair of front and rear gables 14, a top structure 16, and a floor structure 18. As shown in FIG. 1, the side surface 12 is pivotally supported on the side of the top surface structure 16 via a hinge or the like (side surface overturning means) and is rotatable toward the inside of the container. The height of the folded side surface 12 is shorter than the width of the top surface structure 16, and the side surface 12 rotated inward is inserted from the lower side into the inside of the side surface storage section provided under the top surface structure 16. It can be accommodated. Note that the left and right side surfaces 12 are housed in the top structure 16 while being alternately stacked on top of each other at different heights relative to the top structure 16, and are fixed within the top structure 16 by a locking mechanism (not shown). be done. Further, the height at which the left and right side surfaces 12 are pivotally supported by the sides of the top surface structure 16 is determined according to the aspect ratio of the container 10, and in order to alternately fold both side surfaces 12, They may be set at different heights. For example, an ISO standard container has a width W of 2438 mm and a height H of three types: 2896 mm, 2591 mm, and 2438 mm, so the height at which the side surface 12 is pivoted is adapted to each. Note that when the left and right side surfaces 12 are standing upright, the lower sides of the side surfaces 12 can be fixed to the sides of the floor structure 18 by a locking mechanism (not shown).

FIG. 2 is a schematic enlarged view of the top surface of the container 10. In addition, in FIG. 2, the gable surface 14 on the near side is omitted. A pair of forklift holes 16A into which forks of a forklift are inserted are provided near the longitudinal center of the top structure 16 so as to span over the left and right side frames. The forklift hole 16A is used when raising and lowering the top structure 16 in which the side surfaces 12 are accommodated, and the lifting of the top structure 16 is performed using the power of the forklift.

FIG. 3 is a side view showing how the top structure 16 is lowered, and FIG. 4 is a side view showing how the gable 14 is pushed down onto the top structure 16 lowered onto the floor structure 18. It is. Note that FIG. 4(a) shows a state in which the front and rear gables 14 are standing upright on the floor structure 18, and the top structure 16 is lowered onto the floor. 4(b) shows a state in which only the front gable surface 14 is folded over the floor surface structure 18, with the rear gable surface 14 standing upright.

As shown in FIG. 4, the four sides of the gable surface 14 are surrounded by the gable surface frame 20, and inside the gable surface frame 20, for example, a double door 22 and a wall surface 24 are attached. It is also possible to use a door 22 at both the front and rear, a wall surface 24 at both the front and rear, the door 22 at one end, and the wall surface 24 at the other end. Posts 20A that support the top structure 16 are arranged on the left and right sides of the gable frame 20, and the upper and lower ends of the posts 20A are connected through crossbeams 20B. A coupling mechanism 26 is provided at the upper end of the support column 20A, which is used for coupling with a container stacked on top during container operation. Note that a connection mechanism 26 used for connection with the container below is provided on the bottom surface of the floor structure 18 corresponding to the position of the support column 20A. Note that the connection mechanism 26 uses, for example, a structure similar to that of a conventional container.

The lower end of the support column 20A is fixed to the other end of an arm (end surface overturning means) 28 whose one end is pivotally supported by the side frame of the floor surface structure 18. The rotation axis 28A of the arm 28 provided on the side frame of the floor structure 18 is located inside along the longitudinal direction by a predetermined distance D from the center of the gable frame 20 that stands upright. The distance D is determined according to the thickness of the top structure 18 lowered onto the floor. That is, when the gable frame 20 is rotated around the rotation axis 28A and tilted toward the top structure 16 on the floor structure 18, the gable frame 20 is lifted and the gable 14 is moved toward the top structure 16. It is set so that it can be folded almost perfectly onto the top of the screen.

When the gable frame 20 is upright, the top structure 16 is arranged to be sandwiched between the front and rear gable frames 20. When loading cargo, the top structure 16 is placed at the height (first height) of the upper end of the gable frame 20, as shown by the solid line in FIG. Lock mechanisms 30 are provided at predetermined height intervals on the surface of the support column 20A that is in contact with the top surface structure 16. The locking mechanism 30 prevents the top structure 16 from falling by engaging the claw pushed out of the support column 20A by a biasing force such as a spring, and also prevents the top structure 16 from falling when the top structure 16 is raised. It has a latch bolt structure in which the claw is pushed back into the support column 20A.

When used at the first height, the top structure 16 is supported by the lock mechanism 30, and its end is fixed to the upper end of the support column 20A by a lock mechanism (not shown). Note that the gable frame 20, which is now standing upright, is fixed to the frame of the floor structure 18 by a locking mechanism (not shown). When the top surface structure 16 is lowered to the height (second height) in contact with the floor surface structure 18, the lock mechanism 30 is housed in the support column 20A by a lock release mechanism (not shown).

Further, as shown in FIG. 5, an auxiliary support 32 is provided on the frame of the floor structure 18 at a position corresponding to the bottom of the upright support 20A. The auxiliary support column 32 can be tilted inward in the width direction, and is housed in a recess 32A provided in the frame of the floor structure 18 when the gable frame 20 is erected. As shown in FIG. 4(b), when the end surface 14 is folded onto the top surface structure 16 placed on the floor surface structure 18, it becomes possible to stand the auxiliary support column 32 upright. The upright auxiliary column 32 can be fixed in position by a locking mechanism (not shown).

A connecting mechanism 34 having the same function as the connecting mechanism 26 is provided at the upper end of the auxiliary column 32. When the container 10 is completely folded, that is, the front and rear gables 14 are folded over the top structure 16 and fixed to the floor structure 18 by a locking mechanism (not shown), the auxiliary support 32 is When erected, the connecting mechanism 34 is placed at a slightly higher position than the gable 14 folded over the top structure 16. As shown in FIG. 9, when the folded containers 10 are stacked, the connecting mechanism 34 is engaged with and fixed to the connecting mechanism 26 provided on the floor structure 18 of the upper container 10. Note that the same configuration is the same in other embodiments.

On the other hand, when unfolding the container 10 that has been folded to the second height and assembling it to the first height, an operation opposite to the above-mentioned folding operation is performed. That is, after the front and rear gables 14 are stood upright, the top structure 16 is lifted to the first height using a forklift and fixed to the gable frame 20, and then the left and right side surfaces 12 are unfolded to open the side surfaces of the container 10. It is sealed and fixed to the gable frame 20 or the floor structure 18. Note that corners such as both ends of the frame on the gable surface 14 side of the top surface structure 16 are rounded, and when the top surface structure 16 is lifted, the gable surface 14 is raised by contact with the top surface structure 16. It is also possible to have a configuration in which In this case, it is preferable that the surface of the top structure 16 in contact with the gable frame 20 be treated with a special material in consideration of wear resistance and low friction. Examples of surface treatments include coatings (such as Dichlon coating) and plating (such as electroless nickel plating and hard chrome plating), and special materials include ABREX (registered trademark), HARDOX (registered trademark), and EVERHARD ( Possible uses include registered trademarks.

Note that when loading or unloading the container 10, one or both of the left and right side surfaces 12 are placed inside the top structure 16 while maintaining the top structure 16 at the first height. These operations can be performed from the side of the container 10.

As described above, according to the container of the first embodiment, the volume when empty can be further reduced, and as a result, the transportation efficiency when empty can be increased. Moreover, its structure is simple, and the folding work of the container can be easily carried out by a small number of people. The use of auxiliary struts also allows containers that are folded when empty to be safely stacked in a manner similar to conventional containers.

Next, the structure of the container 36 of the second embodiment will be explained with reference to FIG. 6, which is a perspective view showing the rough structure of the container 36, and FIG. 7, which is an enlarged view of the top surface of the container 36. explain. In addition, in FIG. 7, the gable surface 14 on the near side is omitted. The container 36 of the second embodiment has substantially the same configuration as the container 10 of the first embodiment, but the structure of the side surface 12 is different. The same reference numerals are used for the same configuration as in the first embodiment, and the description thereof will be omitted.

The side surface 38 of the second embodiment is vertically divided into a plurality of (even number of) panels, each of which is connected by a hinge. The panel can be folded into a bellows shape toward the inside of the container 36. In the example of FIG. 6, it is divided into two upper and

lower panels

38A and 38B. The upper side of the upper panel 38A is pivotally supported by the side of the top structure 16, and the lower side is connected to the upper side of the lower panel 38B via a hinge. Both ends of the lower side of the lower panel 38B are configured to be movable along guide grooves provided along the support column 20A. The upper and

lower panels

38A, 38B are folded toward the inside of the container 36 in a folding operation. When the lower side of the lower panel 38B reaches the height of the top structure 16, the upper and

lower panels

38A and 38B are accommodated in the top structure 16 in a folded state. The folded left and right side walls 38 are dimensioned so that they do not interfere with each other within the top structure 16. In addition, when dividing into four or more panels, both ends of the lower sides of even-numbered panels from the top are configured to be movable along the support column 20A.

As described above, the same effects as in the first embodiment can be obtained in the container of the second embodiment. In the second embodiment, the lower side of the lower panel 38B is made detachable from the frame of the floor structure 18, and the side surface 38 is lifted while being folded and housed in the top structure 16. It is also possible to adopt a configuration in which the lower side is pivotally supported on the side side of the frame of the floor surface structure 18. In this case, the side surfaces 38 are folded as the top structure 16 descends, and when the top structure 16 contacts the floor structure 18, it is accommodated within the top structure 16. This eliminates the need for a locking mechanism for fixing the upper and

lower panels

38A, 38B within the top structure 16.

Next, the container of the third embodiment will be described with reference to FIG. Similar to the second embodiment, the container of the third embodiment differs from the first embodiment in the side configuration. The other configurations are the same as those in the first and second embodiments, and the same reference numerals are used for the same configurations, and the description thereof will be omitted.

The side wall 42 of the container 40 of the third embodiment includes a plurality of (even number of)

panels

42A, 42B connected by hinges as in the second embodiment, and a tilt plate-like structure that is completely separated from the

panels

42A, 42B. It is divided into a panel 42C.

Panels

42A and 42B have the same configuration as

panels

38A and 38B of the second embodiment. The lower edge of the panel 42C is pivotally supported by the side edge of the floor structure 18, and the panel 42C is rotatable to the inside or outside of the container 40. When fixing the top surface structure 16 at the first height, the

panels

42A, 42B, and 42C are stood upright, and the lower side of the panel 42B and the upper side of the panel 42C are fixed by a locking mechanism (not shown). When the top structure 16 is lowered onto the floor structure 18 and the container 40 is folded, the

panels

42A and 42B are folded and housed in the top structure 16, and the panel 42C is placed on the floor structure 18. can be folded onto the floor. When loading and unloading the container 40 with the side wall 42 open, the panel 42C is rotated to the outside of the container 40.

As described above, the same effects as the first and second embodiments can be obtained in the container of the third embodiment.

Next, the container of the fourth embodiment will be described with reference to FIGS. 10 to 15. FIG. 10 is a perspective view of the container 50 of the fourth embodiment assembled at the first height. The container 50 of the fourth embodiment has a structure in which left and right side surfaces 52 are folded inward along the sides of the floor structure 18. Each side 52 can be staggered over the floor structure 18 along the sides of the floor structure 18 using, for example, hinges. Further, the top surface structure 16 of the container 50 is provided with side surface engaging portions 54 along the lower surface of each side. The other configurations are substantially the same as those in the first to third embodiments, and similar configurations will be designated by the same reference numerals and their descriptions will be omitted.

As shown in the cross-sectional view of FIG. 11, the side surface engaging portion 54 is provided with a groove 54A capable of accommodating the upper end portion of the side surface 52. It is fitted in the groove 54A of the side surface engaging portion 54 in a watertight manner (for example, a sealing member 54B is provided in the groove 54A). The side surface engaging portion 54 partially plays the role of a side surface in the upper part of the container, and the height of the side surface 52 is set to be shorter than the width W. Further, the lower ends of the left and right side surfaces 52 are pivotally supported around rotation axes L1 and L2 provided at different heights with respect to the floor structure 18. With the above configuration, the left and right side surfaces 52 can be folded in a staggered manner on the floor surface of the floor surface structure 18, as shown in the cross-sectional view of FIG.

When folding the container 50 with the top structure 16 assembled at the first height to the second height, as shown in the perspective view of FIG. is lifted and the upper end of the side surface 52 is removed from the groove 54A of the side surface engaging portion 54. Each side 52 is then folded onto the floor surface of the floor surface structure 18. Next, as shown in the perspective view of FIG. 14, the top structure 16 is placed on the side surface 52 folded over the floor structure 18 by a lifting device such as a forklift, and the As in the third embodiment, the front and rear end surfaces 14 are folded over the top surface structure 16 placed on the side surface 52, and the auxiliary support column 32 is erected.

In addition, when a corrugated steel plate is used for the side surface 52, the groove 54A is also structured to correspond to the corrugated shape of the side surface 52, as shown in FIG. mated to.

Further, as a modification of the side engaging part 54, as shown in the cross-sectional view of FIG. It's okay. In this case, the side surface 52 can be operated without significantly lifting the top structure 16.

As described above, in the container of the fourth embodiment, the same effects as those of the first to third embodiments can be obtained, and higher watertightness can be ensured. Note that the configuration of the side

surface engaging portions

54 and 55 of the fourth embodiment can also be applied to the floor surface structure 18 side of the first embodiment. Further, in the fourth embodiment, a groove like a side surface engaging portion is provided along the side of the floor surface structure 18, and the lower end portion of the side surface 52 is fitted into the floor surface structure 18 in a slightly watertight manner. You can also do that.

A gable surface rotating shaft 14B that protrudes outward is provided at the lower end of the support column 20A of the gable surface 14. The gable guide member 56 is attached to the floor structure 18 so as to be disposed along the outside of the support column 20A, and the gable rotation shaft 14B is engaged with the guide groove 56A. Thereby, the end surface rotating shaft 14B can move in the vertical direction within the guide groove 56A.

As shown in FIG. 18, when the left and right side surfaces 52 are folded onto the floor structure 18 and the top surface structure 16 is placed on the folded side surfaces 52, the gable surface 14 (gable surface frame 20 ) is lifted using a lifting device such as a forklift while maintaining an upright position. At this time, the gable surface rotating shaft 14B is moved along the guide groove 56A while the gable surface 14 is kept upright. When the gable surface rotating shaft 14B reaches the upper end of the guide groove 56A, the gable surface 14 is folded onto the top surface structure 16 that has been lowered to the second height with the gable surface rotating shaft 14B as the rotation axis. Here, the length of the guide groove 56A approximately corresponds to the predetermined distance D, for example.

Further, at the four corners of the floor structure 18, there are guide columns (not shown) that maintain the upright state of the gable surface 14 on the floor structure 18 and guide the elevation and descent of the gable surface 14 in the upright state. may be provided. The guide columns protrude vertically upward from, for example, the four corners of the floor surface structure 18, and engage with each of the columns 20A. The guide column is a member shorter than the distance D, and is inserted into a guide hole provided along the longitudinal direction inside the column 20A. When the gable 14 is placed upright on the floor structure 18, the guide support is fitted into the guide hole from the bottom of the support 20A. When the end face 14 (post 20A) is lifted vertically, the support post 20A is moved along the guide post while maintaining the vertical state, and when the end face rotation axis 14B reaches the upper end of the guide groove 56A, the guide post moves into the guide hole. The end face 14 is completely removed from the container, and the end face 14 becomes rotatable toward the inside of the container around the end face rotation axis 14B.

Further, the gable frame 20 is provided with a gable lift member 14A at an appropriately predetermined position, and when folding the gable 14, a wire is hooked onto the gable lift member 14A, and a lifting device such as a forklift lifts the gable. lift up.

They may be provided at a plurality of heights on the gable surface 14, respectively. Further, it may be provided at a location other than the gable frame 20 if there is no problem in terms of strength.

FIG. 19 is a partial perspective view of a container showing the configuration of a modified example of the fifth embodiment. In the fifth embodiment, the gable guide member 56 is arranged outside the support column 20A (outside the frame of the floor structure 18), but in a modified example, the gable guide member 56 is arranged on the frame of the floor structure 18 adjacent to the support column 20A. It will be established. For example, an L-shaped gable rotation shaft 15 that engages with the guide groove 56A of the gable guide member 56 is provided at the lower end of the support column 20A. One end of the L-shaped end surface rotating shaft 15 is attached to the inner surface of the support column 20A in the longitudinal direction of the container and extends along the longitudinal direction of the container, and the other end is bent outward by 90 degrees and engages with the guide groove 56A. will be combined. As a result, the gable surface rotation shaft 15 can be moved up and down along the guide groove 56A, and the gable surface is lowered to the second height with the gable surface rotation shaft 15 as the rotation axis at the upper end of the guide groove 56A. It can be folded up. Note that the shape of the end face rotating shaft 15 is not limited to this embodiment as long as it serves as a rotating shaft, and may be U-shaped, for example. In this case, both ends of the U-shape are attached to the support column 20A. Moreover, the attachment location to the support column 20A is not limited to this embodiment. Moreover, in this modification, the gable surface rotating shaft 15 and the gable surface guide member 56 are configured to be arranged outside the recess of the side surface 52 made of a corrugated steel plate.

As described above, the fifth embodiment can also achieve the same effects as the first to fourth embodiments.

In addition, when the container of this embodiment is used as a loading box of a truck or a freight car on a railway, it can be used on the assumption that the container will be attached to and detached from the chassis of a truck or freight car, but it may be used without assuming that it will be removed. It can also be used in any condition.

Here, the configuration of each part described in each embodiment can be applied independently to other embodiments as long as there is no structural contradiction. For example, the configuration in which the side surface of the second and third embodiments is divided into a plurality of panels is also applicable to the side surface of the fourth and fifth embodiments. Further, the configuration of the gable face overturning means can also be replaced in each embodiment, and other configurations can also be replaced as long as they do not conflict structurally.
