Abstract

To downsize a structure of a gable column of a container, reduce a load on the gable column when the container is lifted, broaden an opening width for taking out/putting in a cargo and a volume inside the container, and make the container lighter.SOLUTION: In a container 1, an external force is applied to a front gable column 19A and a rear gable column 49A when a connecting tool of a top lifter, a front gable side metal fitting 15R and a rear gable side metal fitting 17R are connected and the container 1 is hung and moved up and down by the top lifter, but since the rear gable side metal fitting 17R is mounted on an upper end of the rear gable column 49A on a rear gable surface 7 side, flexure moment is reduced against the rear gable column 49A, the influence of the external force is reduced, and the load of the external force is reduced. On the other hand, since the front gable side metal fitting 15R is offset from a wall surface of the front gable surface 5 on a front gable surface 5 side, flexure moment is generated against the front gable column 19A, and the influence of the external force increases. However, since the front gable surface 5 side has a wall structure and the external force applied to the front gable column 19A is borne by the wall surface, it becomes possible to reduce the external force on the front gable column 19A.SELECTED DRAWING: Figure 1

JP, 2013-56677, A

By the way, when using a top lifter for a container that is shorter than the total length of the container subject to cargo handling work, it is necessary to install the span of the corner fittings of the container according to the span of the top lifter side connector (twist lock pin). There is.

In the case as described above, the present invention downsizes the structure of the gables of the container, reduces the burden on the gables when the container is lifted, and reduces the opening width for loading and unloading the luggage and the interior volume of the container. It is about expanding and reducing the weight of the container.

(Aspect of the invention)
The following aspects of the invention exemplify the aspects of the present invention and are described by itemizing them in order to facilitate understanding of various components of the present invention. Each of the following items does not limit the technical scope of the present invention, while referring to the best mode for carrying out the present invention, a part of the components of each item is replaced, deleted, or further An aspect in which other constituent elements are added can also be an aspect of the present invention.

(1) A container having a front gable surface having a wall structure and at least one surface having a rear gable surface and a side surface having an opening and having a door in the opening, A front gable, a pair of gables, a side upper beam and a side girder that extend along the longitudinal direction of the container and connect the sides of the pair of gables and the pair of gables, and the width of the container. A front girder upper beam and a front girder lower beam that extend along the direction and connect the sides of the pair of gable girders, and a rear girder upper beam and a rear girder that extend between the sides of the pair of rear gable columns extending along the width direction of the container. A container main body including a lower beam, a first corner fitting fixed to the upper ends of the pair of rear gable pillars, offset from the wall surface of the front gable surface, and connected to the upper ends of the pair of front gable pillars via a connecting portion. And a second corner metal fitting (Claim 1).

In the container according to this section, the front gable surface of each of the gable surfaces has a wall structure, and at least one of the rear gable surface and each of the side wall surfaces has an opening, and the opening is provided with a door. With this structure, the strength of the front gable surface is equal to or higher than that of the rear gable surface having the opening. Further, the container includes a container main body including a pair of front girder columns, a pair of rear gable columns, side upper beams, side lower beams, front gable upper beams, front gable lower beams, rear gable upper beams and rear gable lower beams, and upper ends of the pair of rear gable columns. And a second corner metal fitting that is offset from the wall surface of the front gable surface and that is connected to the upper ends of the pair of front gable pillars via a connecting portion. With this structure, when the container of the top lifter is connected to the first corner fitting and the second corner fitting and the container is hung up and down by the top lifter, a pulling force is applied to the pair of front girders and the pair of rear girders. Although external force such as bending force is applied, on the rear girder surface side, the first corner metal fitting is attached to the upper ends of the pair of rear gable pillars, so the bending moment is reduced with respect to the pair of rear gable pillars, and the tensile force and bending force are increased. The influence of external force such as force is reduced, and the burden of external force is reduced. On the other hand, in the front gable surface, the second metal fitting is offset from the wall surface of the front gable surface, so that a bending moment is generated with respect to the pair of front gable pillars, and the influence of external forces such as tensile force and bending force increases. However, since the front gable surface has a wall structure, that is, the outer wall bears external forces such as tensile force and bending force applied to the pair of front gable columns on the wall surface. The external force such as is reduced.

More specifically, the outer plate is a plate-shaped member having a rectangular shape when viewed from the front, and the first inner member has a U-shape in cross section, and the two legs forming the U-shape are outer plates. The second inner member is L-shaped in cross-section and is located closer to the inside of the container in the width direction of the container than the first inner member, and one leg of the L-shaped outer plate is joined to the outer plate. It is joined to the inner surface and the other leg is joined to the first inner member. With such a configuration, the shapes of the outer plate, the first inner member, and the second inner member do not become complicated, and the pair of front girders has a simple structure. Even with this configuration, since the front grommet has a wall structure as described in (1) above, the required strength of the grommet is ensured, and even when the container is hung on the top lifter, the outer wall is used. The load of external force such as tensile force and bending force on the pair of front gables is reduced. Therefore, the cross-sectional areas of the pair of front gable columns can be reduced as much as possible while ensuring the required strength of the pair of front gable columns, and the weight and size of the pair of front gable columns can be reduced. Further, due to the downsizing of the pair of front gables, the inner surfaces (the surfaces on the indoor side) of the pair of gables are located closer to the outermost edge of the container, which contributes to an increase in the interior volume of the container. Further, in the case where one side surface or both side surfaces of the container has a structure having an opening portion, the cross-sectional area of the pair of front gable pillars is reduced, so that a pair of rear gable pillars from the end surface of the pair of front gable pillars on the inner side in the longitudinal direction of the container. The dimension of the end face of the container on the indoor side in the longitudinal direction (that is, the dimension of the opening width in the longitudinal direction of the container) becomes large, which contributes to the expansion of the area of the opening.

(3) In the above item (1) or (2), the pair of rear girders includes an outer member and an inner member joined to an inner surface of the outer member, and the outer member is a chamber of the container.

A second leg portion that is bent at a substantially right angle and extends toward the inner side in the width direction of the container, wherein the inner member has a U-shape in cross section, and one leg that forms the U-shape. Is joined to the inner surface of the flat portion of the outer member, and the outer surface of the other leg portion is joined to the inner surface of the second leg portion of the outer member (claim 3).

In the container according to this section, the structure of the pair of rear girders includes an outer member and an inner member joined to the inner surface of the outer member. More specifically, the outer member includes a first leg extending from the inner side of the container to the outer side in the width direction of the container, and, following the first leg, from the base end of the first leg to the inner side in the longitudinal direction of the container. And a flat portion that extends along the longitudinal direction of the container, a crank portion that bends in a crank shape toward the inside of the container in the width direction of the container, and a width of the container that follows the crank portion. And a second leg portion that is bent substantially at right angles to the inside of the container and extends to the inside of the container in the width direction. The inner member has a U-shaped cross-section, and one leg that forms the U-shape is joined to the inner surface of the flat surface of the outer member, and the outer surface of the other leg is the second leg of the outer member. Are joined in a manner of contacting the inner surface of the. Even with such a configuration, the configuration in which the first corner metal fitting is attached to the upper ends of the pair of rear gable posts described in the above item (1) allows the pair of rear gable posts even when the container is suspended by the top lifter. The load of external force such as tensile force, bending force, etc. on the shaft is reduced. Therefore, the cross-sectional area of the pair of rear gable columns can be reduced as much as possible while ensuring the required strength of the pair of rear gable columns, and the weight and size of the pair of rear gable columns can be reduced. Further, due to the miniaturization of the pair of rear gable posts, the inner surfaces (the surfaces on the indoor side) of the pair of rear gable pillars are located closer to the outermost edge of the container, which contributes to an increase in the interior volume of the container. Further, in the case where one side surface or both side surfaces of the container has a structure having an opening, the cross-sectional area of the pair of rear gable pillars is reduced, so that the pair of rear gable pillars are paired with each other from the end surface on the indoor side in the container longitudinal direction. The dimension of the end face of the front gable of the above-mentioned container on the indoor side in the longitudinal direction of the container (that is, the opening width dimension in the longitudinal direction of the container) is increased, which contributes to the expansion of the area of the opening.

And the outer member is formed thicker than the inner member. With such a configuration, the number of parts is reduced to the necessary minimum, and the lateral lower beam has a simple structure. In addition, since the outer member is formed to be thicker than the inner member, the required height of the lower side beam is ensured, the height dimension of the lower side beam is made as small as possible, and the weight of the lower side beam is reduced. It contributes to miniaturization and miniaturization. Further, due to the downsizing of the lower side beam, the inner surface (the surface on the indoor side) of the lower side beam is located closer to the outermost edge of the container, which contributes to an increase in the interior volume of the container. Further, when one side or both sides of the container have a structure with an opening, the height of the lower side beam is reduced, so that the inside member of the lower side beam is separated from the inner end surface in the height direction of the container. The dimension of the inner end surface of the inner member of the side upper beam in the height direction of the container (that is, the height dimension of the opening in the height direction of the container) is increased, which contributes to the expansion of the area of the opening.

It Here, "substantially on the same plane" means not only completely identical, but also including a positional error within a permissible range in terms of structure and dimensional accuracy to exert the above-mentioned action.

As described above, according to the container 1 having the above-described configuration according to the embodiment, the following operational effects can be obtained. In the container 1, the rear gable surface 7 and the side wall surfaces 3L and 3R of the gable surface have openings 11L, 11R, and 11B, while the front gable surface 5 has a wall structure. Therefore, the strength on the front end face 5 side is equal to or higher than the strength on the wall surface of the rear end face 7 having the opening 11B. Here, the container 1 connects the connector of the top lifter, the pair of rear girder side metal fittings 17L, 17R, and the pair of front gable pillars 19A, 19B, and when the container 1 is hung by the top lifter and moved up and down, External forces such as tensile force and bending force are applied to the columns 19A and 19B and the pair of rear girder columns 49A and 49B. At this time, on the rear girder surface 7 side, since the rear girder side fittings 17L and 17R are attached to the upper ends of the pair of rear gable pillars 49A and 49B, the bending moment is reduced with respect to the pair of rear girder pillars 49A and 49B. It is possible to reduce the influence of external force such as bending force and bending force and reduce the load of external force. On the front gable surface 5 side, on the other hand, since the pair of front gable side fittings 15L and 15R are offset from the pair of front gable columns 19A and 19B, a bending moment is generated in the pair of front gable columns 19A and 19B, and a tensile force and a bending force are generated. The influence of external force such as force increases. However, since the front gable surface 5 side has a wall structure, that is, the outer wall plate 25 also bears external forces such as tensile force and bending force applied to the pair of front gable pillars 19A and 19B on the wall surface. , 19B, external forces such as tensile force and bending force are reduced. As a result, the cross-sectional area of the pair of front gable pillars 19A, 19B is reduced as much as possible while ensuring the required strength of the pair of front gable pillars 19A, 19B, and the weight and size of the pair of front gable pillars 19A, 19B are reduced. Will contribute to.
