Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated container for transporting physical distribution, and more particularly to a prefabricated container in which a plurality of side plates are erected to form an article storage space inside.

Conventionally, during transportation or loading and unloading work, side plates are erected on the pallet in a peripheral wall shape to assemble them into a container shape with an article storage space inside, while at the time of return, the side plates are disassembled or folded to reduce the container size. Many prefabricated containers that can be reduced are used.

As such an assembling type container, for example, a lower metal frame is fixed on the upper surface of a pallet that can be handled by a forklift, and four side panel-shaped side plates are erected inside the lower metal frame in a peripheral wall shape. It is known that a predetermined container shape is formed by forming an article storage space in the.

For example, as shown in FIG. 7, the container disclosed in Patent Document 1 is installed on a second side plate 920 adjacent to a spread prevention pin hole 912 formed on a holding plate 911 of a first side plate 910. The first side plate 910 and the second side plate 920 are connected to each other by inserting the spread prevention pin 921 that is provided and further contacting the side surface of the slide pin (spindle) 922 of the round drop fitting with the pressing plate 911. It is supposed to be done.

In addition, for example, as shown in FIGS. 8A and 8B, the container disclosed in Patent Document 2 has a second side plate adjacent to the hook portion 931 at the side end of the first side plate 930. The connecting metal fitting 941 rotatably provided on the 940 is locked, and the connecting metal fitting 941 locked on the hook portion 931 is fixed by using the pin 943 of the stopper member 942. The second side plate 940 is connected.

Utility model registration No. 3201465 (Fig. 12) Japanese Patent No. 3895852 (FIGS. 6 and 7)

As at least one side plate of the container, there may be adopted a configuration in which two divided side plates (an upper side plate and a lower side plate) are connected by a hinge, that is, a center-folded side plate in which one side is folded in two. In such a center-bending type side plate, the upper side plate is rotatable with respect to the lower side plate, and the upper side plate can be rotated outward to face the article storage space inside the container. The upper side plate of the center-bend type side plate is connected to the adjacent side plate when the article is conveyed, etc., while it is easily connected to the adjacent side plate when the article is taken in and out of the article storage space. It is desirable that the structure can be released.

When the disclosed technique of Patent Document 1 is applied to the connection between the upper side plate and the adjacent side plate of the center folding type side plate, the spread prevention pin formed on the pressing plate of the upper side plate is used to spread the adjacent side plates. The upper side plate and the adjacent side plate can be connected to each other by fitting them into the prevention pin holes.

However, when removing the spread prevention pin from the spread prevention pin hole, slide the slide pin to separate its side surface from the holding plate, and then the spread prevention pin was formed. There is a problem that it is necessary to incline the adjacent side plates inward.

Further, since the upper side plate is connected to each of the two adjacent side plates, it is necessary to remove the expansion preventing pin from the expansion preventing pin hole at the two connecting portions at both ends of the upper side plate. Specifically, on one side plate side, tilt the side plate inward to remove the expansion prevention pin from the expansion prevention pin hole, and on the other side plate side, tilt the side plate inward to prevent expansion. It is necessary to remove the expansion prevention pin from the pin hole.

However, if you try to release the connection on one side plate side after releasing the connection on the other side plate side, the expansion prevention pin is re-inserted into the expansion prevention pin hole on the side plate side where the connection should have been released. It may happen. To avoid this, on the side plate side that has been disconnected, while keeping the side plate tilted inward (for example, while holding the side plate tilted inward by hand), the other side plate There is a problem in that it is necessary to release the connection on the side or release the connection on the one side plate and the other side plate at the same time, and it is not possible to realize a container with excellent convenience.

In addition, when the disclosed technique of Patent Document 2 is applied to the connection between the upper side plate of the middle folding type side plate and the adjacent side plate, when the connecting metal fitting and the stopper member are provided on the adjacent side plate, the hook portion of the upper side plate is provided. It is possible to connect the upper side plate and the adjacent side plate by locking the connection member and further fixing the connection member by using the pin of the stopper member.

However, in this configuration, the connecting metal fittings and the stopper members provided on the adjacent side plates serve as protrusions to the upper part of the container, which may be an obstacle when handling the container, or the upper lid may not be able to tightly cover the upper part of the container. There is a problem called.

In view of the above problems, the present invention aims to improve the convenience of an assembling container that uses a center-foldable side plate in which at least one side plate is folded in two, and in particular, a center-foldable type container An object of the present invention is to provide a prefabricated container capable of easily connecting and disconnecting an upper side plate of a side plate and an adjacent side plate, and releasing the connection.

On the other hand, the upper side plate 41A, which is connected to the lower side plate 41B by the hinge 41C, is rotatable with respect to the lower side plate 41B toward the outer surface side away from the article housing space 2. The upper side plate 41A can be fixed to the third and fourth side plates 43 and 44 by using a fixing mechanism.

The fixing mechanism for fixing the upper side plate 41A to the third and fourth side plates 43 and 44 is, for example, the round drop metal fitting 60 as described above, and the slide pin 62 is provided along the vertical frame portion of the upper side plate 41A. Direction (vertical direction in the assembled shape).

When the first upper side plate 41A is fixed to the third and fourth side plates 43 and 44, the slide pins 62 provided on both side ends of the upper side plate 41A are moved to the release side stop positions, respectively, and The side plate 41A is rotated with respect to the lower side plate 41B so that the vertical frame portions of the upper side plate 41A come into contact with the vertical frame portions of the third and fourth side plates 43 and 44. That is, a state in which the upper side plate 41A and the lower side plate 41B form substantially the same surface, in other words, a state in which the upper side plate 41A and the lower side plate 41B are substantially coplanar side surfaces erected in the vertical direction with respect to the pallet 11. To place.

The fixed plate 413A of the first upper side plate 41A is formed with a cutout portion 414A, and the slide pin 62 is at the release side stop position retracted away from above the cutout portion 414A. When the vertical frame portion of the upper side plate 41A comes into contact with the vertical frame portions of the third and fourth side plates 43 and 44, the slide pin receiving metal fittings 63 of the third and fourth side plates 43 and 44 are fixed to the fixed plate 413A. It fits in the notch 414A without interfering with each other and is exposed on the fixing plate 413A.

In this state, when the slide pins 62 provided on both ends of the upper side plate 41A are moved to the fixed side stop positions, the slide pins 62 (members extending in the vertical direction in the assembled shape) are exposed on the fixed plate 413A. It is in a state of being inserted into the slide pin receiving fitting 63 (a ring-shaped member that spreads in the horizontal direction in the assembled shape) provided on the third and fourth side plates 43 and 44.

When the slide pin 62 is inserted into the slide pin receiving fitting 63 which is a ring-shaped member, the slide pin receiving fitting 63 restricts the horizontal movement of the slide pin 62. More specifically, when the slide pin 62, which is a member extending in the vertical direction in the assembled shape, is inserted into the slide pin receiving metal fitting 63, which is a ring-shaped member that expands in the horizontal direction, the slide pin 62 moves in the horizontal direction. Even if an attempt is made, the side surface of the slide pin 62 comes into contact with the ring-shaped inner surface of the slide pin receiving fitting 63 and cannot freely move. The horizontal movement of the slide pin 62 is regulated by the slide pin receiving metal fitting 63, whereby the rotation of the upper side plate 41A on which the slide pin 62 is provided with respect to the lower side body 41B is regulated.

In this way, by inserting the slide pin 62 into the slide pin receiving metal fitting 63 and restricting the rotation of the upper side plate 41A with respect to the lower side body 41B, the upper side plate 41A of the first side plate 41 becomes the third and fourth sides. The first side plate 41 is fixed in contact with the side plates 43 and 44, and the first side plate 41 becomes one side plate standing upright in the vertical direction with respect to the pallet 11, and the volume of the article storage space 2 is secured. Further, for example, even if an article housed in the article housing space 2 pushes the upper side plate 41A of the first side plate 41 from the inside, the rotation of the upper side plate 41A with respect to the lower side plate 41B is restricted, and thus the upper side plate 41A is restricted. The shape in which 41A and the lower side plate 41B form substantially the same surface is maintained.

On the other hand, when the fixation of the first upper side plate 41A to the third and fourth side plates 43 and 44 is released, the slide pins 62 provided on both side ends of the upper side plate 41A are separated from above the notch portion 414A. It should be moved to the release side stop position that has been retracted. As a result, the side surface of the slide pin 62 is separated from the ring-shaped inner surface of the slide pin receiving fitting 63, so that the slide pin 62 can move in the horizontal direction, and the upper side plate 41A on which the slide pin 62 is provided is moved downward. It becomes possible to freely rotate with respect to the side body 41B.

In this manner, the slide pin 62 is retracted from the slide pin receiving metal fitting 63 so that the upper side plate 41A can freely rotate with respect to the lower side body 41B. The side plate 41A can be opened to face the article accommodation space 2, and the articles can be easily taken in and out of the article accommodation space 2.

The first upper side plate 41A is fixed to the adjacent one side plate only by moving the slide pin 62 on the adjacent one side plate to the fixed side stop position so as to be inserted into the slide pin receiving fitting 63. Thus, the rotation of the first upper side plate 41A with respect to the lower side plate 41B is regulated to some extent. The state in which the first upper side plate 41A is fixed to only one adjacent side plate is not released even if the user releases his hand or slightly moves the first upper side plate 41A, for example.

Therefore, when fixing the first upper side plate 41A to the third and fourth side plates 43, 44, it is not necessary to move the slide pins 62 provided at both ends of the upper side plate 41A at the same time to the fixed side stop position. Instead, for example, after moving the slide pin 62 on the side of the third side plate 43 (one side plate) to the fixed side stop position to fix the upper side plate 41A and the third side plate 43, the fourth side plate 44 (the other side plate) The side side plate) side slide pin 62 may be moved to the fixed side stop position to fix the upper side plate 41A and the fourth side plate 44. Further, for example, it is not necessary to hold the previously fixed side by hand so that the fixed state is not released.

The same applies to the case where the state in which the first upper side plate 41A is fixed to the third and fourth side plates 43 and 44 is released, for example, the slide pin 62 on the third side plate 43 (one side plate) side. After moving to the release side stop position, the slide pin 62 on the fourth side plate 44 (the other side plate) side may be moved to the release side stop position. Similarly, for example, it is not necessary to hold the previously released side by hand so as not to return to the fixed state again.

The assembling container 1 of the present invention is not limited to the above-described present embodiment. For example, in the above-described present embodiment, the slide pin receiving fitting 63 has a ring shape, but the shape of the slide pin receiving fitting 63 contacts the side surface of the slide pin 62 arranged at the fixed side stop position. It suffices that the upper side plate 41A can be restricted from rotating with respect to the lower side plate 41B. The slide pin receiving member 63 may be a ring-shaped member with a part cut away, or may be a protruding member that contacts the side surface of the slide pin 62 and restricts the horizontal movement of the slide pin 62. Good.
