Description

Container conforming to ISO standard

The present invention relates to a container conforming to the ISO (International Organization for Standardization) standard.

A container that conforms to the ISO standard satisfies the predetermined outer dimensions, the predetermined total gross weight, the predetermined strength condition, and the like specified in the ISO standard. This enables efficient container transportation, such as the ability to stack a number of containers of the same shape during sea or land transportation, and also provides cargo maintenance and cargo transportation by having a predetermined strength. The safety of the ship or vehicle is ensured. Further, in a container conforming to the ISO standard, there is only one door on one side of two surfaces along the short direction of the container. Hereinafter, this is referred to as a rear door.

On the other hand, apart from containers conforming to the ISO standard, as seen in Patent Document 1, for example, emphasis is placed on workability when loading and unloading cargo, and in addition to the rear door described above, the door is placed in the longitudinal direction of the container. Some have two sides along one or both sides. Hereinafter, this is referred to as a side door. According to this, when it is desired to carry in / out a predetermined cargo, it is possible to open only the side door nearest to the cargo and carry in / out only the cargo or a small number of cargo around the cargo.

EP1136291A1

As described above, in the container conforming to the ISO standard, there is only one door on the rear door for loading and unloading cargo. In this case, it is difficult to carry out only the cargo in the innermost part of the container conforming to the ISO standard (the place in the foremost side opposite to the rear door), and it is in front of the cargo in the innermost part. Unless almost all cargo is unloaded, the desired cargo cannot be unloaded. Also, if you have forgotten to load the cargo that should originally be loaded in the innermost part (frontmost part), it is difficult to load it in the innermost part if other cargo has already been loaded. It is. However, since the container conforming to the ISO standard is configured by the panel member of the wall surface except for the rear door, the predetermined strength condition defined by the ISO standard can be easily satisfied.

On the other hand, the container of Patent Document 1 has high workability when loading and unloading cargo, but has a large opening for attaching a door, and has a lower strength than a container defined by the ISO standard. You may not be able to meet.

Thus, good workability and strength when loading and unloading cargo in a container are in a trade-off relationship.

The present invention has been made under such a background, and conforms to the ISO standard that can satisfy the strength conditions defined in the ISO standard while maintaining good workability when loading and unloading cargo. The objective is to provide a compliant container.

The container of the present invention includes a cargo compartment in which cargo is loaded, and a side door comprising a pair of doors that are provided on the side surface in the longitudinal direction of the cargo compartment and open from side to side from the center in the longitudinal direction of the cargo compartment. The container conforms to at least the ISO standard, and the floor surface of the cargo compartment is supported by a support portion formed along the outer periphery of the floor surface, and the support portion is constituted by square pipes stacked in two upper and lower stages. Is.

Further, it is preferable that at least the upper square pipe among the square pipes stacked in the upper and lower stages has a surface included in a plane including the outer wall surface of the side door.

According to the present invention, a container conforming to the ISO standard (hereinafter simply referred to as a container) capable of satisfying the strength condition defined in the ISO standard while maintaining good workability when loading and unloading cargo. Can provide.

The configuration of the container 1 will be described with reference to FIGS. FIG. 1 is a diagram illustrating a state in which a vehicle 2 on which a container 1 is mounted is viewed from the side. FIG. 2 is a side view of the container 1 (a view showing only the container 1 in FIG. 1). FIG. 3 is an enlarged view showing a part of the container 1 shown in FIG. FIG. 4 is a top view of the container 1. In addition, in the top view like FIG. 4, the state which abbreviate | omitted illustration of the ceiling panel and the corner metal fitting 4 is shown in order to make the state of the side door 3 and the rear door 3B easy to understand.

The container 1 is carried on a vehicle 2 or a ship (not shown) as shown in FIG. Here, a 40 ft (feet) container conforming to the so-called ISO standard will be described. The 40 ft container conforming to the ISO standard has an outside dimension of 9 ft 6 in (inch) (2896 mm (millimeters)) × 8 ft (2438 mm) × 40 ft (12192 mm) in length and a maximum total mass of 30480 kg (kg). .

The container 1 has a rectangular parallelepiped cargo compartment 5 as shown in FIGS. Corner metal fittings 4 are disposed at the corners of the cargo compartment 5. The side wall 3 that forms the longitudinal direction of the cargo compartment 5 has a side door 3, and the rear part is located on one of the two side walls in the short direction perpendicular to the side wall in the longitudinal direction (the side facing the rear of the vehicle 2). It has a door 3B. The side door 3 includes small doors 3R-1 and 3L-1 and small doors 3R-2 and 3L-2. The small doors 3R-2 and 3L-2 are attached to the main body of the container 1 by a hinge 6a so as to be freely opened and closed. Further, the small door 3R-1 and the small door 3R-2, and the small door 3L-1 and the small door 3L-2 are rotatably connected by a hinge 6b. Further, the rear door 3B is attached to the main body of the container 1 so as to be freely opened and closed by a hinge 6c. As shown in FIG. 2, the length L1 in the longitudinal direction of the small doors 3L-1, 3R-1 is shorter than the length L2 in the longitudinal direction of the small doors 3L-2, 3R-2.

The small doors 3R-1, 3L-1 are provided with a locking portion 7a, the small doors 3R-2, 3L-2 are provided with a locking portion 7b, and the door 3B is provided with a locking portion 7c. Is provided. The locking portions 7a, 7b, 7c fix the small doors 3R-1, 3L-1, 3R-2, 3L-2 and the rear door 3B to the frame of the cargo compartment 5 when they are closed. Is. The configuration of the locking portions 7a and 7b will be described with reference to FIG. In addition, since the latching | locking part 7c is the same structure as the latching | locking part 7a, description is abbreviate | omitted.

As shown in FIG. 3, the locking portion 7a includes a cam 70a, a cam guide 71a, bearings 72 and 73, a locking bar 74, a handle 75a, a handle receiving portion 76a, and a handle rotating portion 77a. The cams 70a are formed at both ends of the locking bar 74, and are rotated together with the locking bar 74 to be fitted with or released from the cam guides 71a attached to the cargo compartment 5. At this time, the locking bar 74 is manually rotated by the user moving the handle 75a in the horizontal direction (depth direction in the figure). When the side door 3 is closed, the cam 70a is engaged with the cam guide 71a in a state where the handle 75a is placed on the handle receiving portion 76a.

As shown in FIG. 3, the basic structure of the locking portion 7b is the same as that of the locking portion 7a. However, the cam 70b, the cam guide 71b, the handle 75b, the handle receiving portion 76b, And the attachment position of the handle | steering-wheel rotation part 77b differs from the latching | locking part 7a. That is, as shown in FIG. 3, the handle receiver 76a of the locking portion 7a is mounted on the small door 3L-1, and the positions of the handle 75a and the handle rotating portion 77a are on the small door 3L-1. At the bottom. On the other hand, the handle receiving portion 76b of the locking portion 7b is attached to the outer wall of the cargo compartment 5, and the positions of the handle 75b and the handle rotating portion 77b are at the lower part outside the small door 3L-2. Accordingly, the mounting positions of the cam 70b and the cam guide 71b are also lowered further below the cam 70a and the cam guide 71a.

Further, as shown in FIG. 3, the plurality of hinges 6a that rotatably support the small door 3L-2 and the cargo compartment 5 are adjacent to each other at the uppermost part and the lowermost part of the small door 3L-1, and the hinge group 60, 61 are formed. The same applies to the hinge 6a between the other small door 3R-2 and the cargo compartment 5 (not shown).

Furthermore, the upper and lower two-stage square pipes 8U and 8L are provided at the lower part of the container 1 as support parts. The square pipe 8U and the square pipe 8L are joined by welding. As shown in FIG. 5, a cam guide 71b is attached to the upper square pipe 8U. That is, the surface of the square pipe 8U to which the biting guide 71b is attached is included in substantially the same plane as the surface of the outer wall of the small door 3L-2. A floor surface 9 is attached to the square pipe 8U.

(About the opening 30, 30B of container 1 and square pipes 8U1, 8L1, 8U2, 8L2, 8 (R), 8 (L))
The lower diagram of FIG. 6 shows the openings 30 and 30B from which the side door 3 and the rear door 3B of the container 1 shown in the upper diagram of FIG. 6 are removed. FIG. 7 is a perspective view of the container 1 with the side door 3 and the rear door 3B removed. The side door 3 and the rear door 3B are attached to the openings 30 and 30B. As shown in FIG. 7, the floor surface 9 of the container 1 includes two upper and lower square pipes 8U1, 8L1, 8U2, and 8L2 along the longitudinal direction, and square pipes 8 (R) and 8 (L) along the short side direction. It is supported by the frame comprised by these. The four square pipes 8U1, 8U2, 8 (R), 8 (L) are welded to form a rectangle. Further, the square pipes 8L1 and 8L2 are welded to the lower portions of the square pipes 8U1 and 8U2.

The container 1 has openings 30 and 30B for attaching the side door 3 and the rear door 3B, as shown in FIGS. 6 shows the container 1 having the side door 3 and the rear door 3B in the cargo compartment 5, and the lower part of FIG. 6 shows the openings 30, 30B from which the side door 3 and the rear door 3B are removed. Show. In addition, the ratio [(L12 / L11) × 100] (%) of the length L12 of the opening 30 that appears when the side door 3 is opened to the total length L11 of the container 1 is referred to as an opening ratio. The corner bracket 4 is for joining the frames and the pillars constituting the container 1 to each other by welding, and slightly protrudes from the cargo compartment 5. The total length of the container 1 for calculating the aperture ratio may not include the protruding portion of the corner bracket 4. Here, it is assumed that the total length of the container 1 (L11 described later) does not include the protruding portion of the corner bracket 4. Therefore, when calculating the aperture ratio, 12000 mm is adopted as the total length (L11) of the container 1.

The larger the opening ratio is, the lower the strength of the container 1 is. However, it is known that the opening ratio up to 95% is within an allowable range that can satisfy the strength defined in the ISO standard ( (See Japanese Patent Application No. 2011-064906). In addition, if the opening ratio is less than 60%, it takes a pallet moving distance of two or more pallets to carry in and out of the pallet, and workability is remarkably reduced. Therefore, it is appropriate that the lower limit of the opening ratio is 60%. is there. Therefore, the maximum range that the aperture ratio can take is 60% to 95%. In addition, the pallet assumes the flat pallet for the consistent transport based on JISZ0105 standard, The dimension is 1100 mm long x 1100 mm wide x 144 mm in height. However, in consideration of the actual usage situation of the container 1, considering the vibration during the transportation of the container 1, the opening ratio is assumed to be within 90% even in consideration of the actual usage situation of the container 1 up to 90%. Is appropriate. Furthermore, when the aperture ratio is 75% or more, the pallet moving distance of less than two pallets is sufficient for loading and unloading pallets, and the workability of loading and unloading pallets is improved. Therefore, it is appropriate that the aperture ratio is 75% to 90%.

Further, wall members 10F and 10R are disposed on both sides of the opening 30 in the longitudinal direction. Since there is no door in the front part of the container 1, the strength can be secured more than the rear part having the opening 30B of the rear door 3B. Therefore, the area of the wall surface 10F may be smaller than the area of the wall surface 10R. However, in order to reduce the number of parts of the container 1, it is preferable to use the same panel member on the wall surfaces 10F and 10R. Therefore, here, the areas of the wall surfaces 10F and 10R are equal to each other on the left and right.

(Regarding opening and closing of the side door 3 and the rear door 3B of the container 1)
The opening / closing mechanism of the side door 3 and the rear door 3B of the container 1 will be described with reference to FIG. In addition, in FIG. 8, illustration of the latching | locking part 7a, 7b, 7c is abbreviate | omitted. FIG. 8 is a diagram illustrating a state in which the door of the container 1 is opened. As shown in FIG. 8, the side door 3 and the rear door 3B of the container 1 are opened and closed by hinges 6a, 6b, 6c, and the small doors 3R-1, 3R-2, 3L-1, 3L-2 are hinges 6b. It is a structure folded by. In FIG. 8, the small door 3L-2 is not opened.
