However, there is still a problem that it is not always easy to take out the contents from the opening because the entire side cover projects 180 degrees downward or 90 degrees sideways. In other words, when the side lid is opened 180 degrees downward, the opening of the lower container is closed in the stacked state, so that it is difficult to remove the contents from the lower box, and the side lid is 90 degrees sideways. In the open state, the side lid is in the way, and the worker can take out the contents only with the arm extended considerably, or it may be difficult to take out the contents at the back. .

In addition, in the conventional opening / closing mechanism using the side lid, a special lock mechanism manufactured separately must be provided between the upper part of the side lid and the upper part of the side wall opening. There is still room for improvement in terms of the expense of manufacturing and installation.

Accordingly, it is an object of the present invention to perform an opening operation on a part of the side cover and an opening operation in a state in which the side cover is entirely folded. The opening state can be selected accordingly, and the operation of taking out and storing the contents from the opening can be easily performed even in the stacked state, and the locking operation on the side wall of the side cover is also manufactured separately. Provided is a container which can be easily and reliably performed without using a special lock mechanism, and furthermore, the opening is reinforced by the engagement between the side lid and the side plate, and as a result, the strength of the opening is suppressed to be low.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides an opening in a side plate,
The present invention relates to a container in which a side cover that opens and closes the opening is rotatably provided at the opening. (A) The side cover is formed of an upper member and a lower member that can be bent via a hinge. The lower member is rotatably connected to a side plate below the opening via a link. (C) The link and the lower side plate are rotatably connected by a first shaft, and the link and the side cover are connected. (D) between the upper member and the lower member of the side cover and the side plates on both sides of the opening; Is characterized in that an engagement portion is provided for locking the horizontal movement and releasing the engagement in the pulled-out state.

In the present invention, the configuration (a) allows the side cover to be folded, allows the opening operation when the side cover is folded, and allows the opening to be closed when the side cover is straightened. Becomes

[0010] Further, according to the configuration (b), the entire side cover can be rotated with respect to the side plate, so that the side cover can be easily opened and closed, and a link is interposed between the two.
In conjunction with the link connection method (c) described later, the turning operation of the side cover and the locking and unlocking operations are performed smoothly.

Further, in the configuration (c), the link is provided rotatably with respect to the lower side plate about the first axis, and accordingly, the link is rotatable about the first axis. At the same time, the lower side lid member is provided rotatably with respect to the link by the second shaft, and accordingly, the lower side lid member becomes rotatable about the second axis. In addition, the side plate lower member is provided with a long hole (a long hole extending vertically in the locked state), and the second shaft is provided so as to pass through the long hole. The whole can be pulled out in the direction of the long hole.

Further, as in the configuration (d), the upper and lower members of the side cover and the side plates on both sides of the opening are provided.
An engaging portion for locking the horizontal movement and disengaging in the pulled-out state is provided, so that when the side cover is pulled out, the side cover and the side plate are disengaged and the side cover is folded. When the one side lid is pulled down, the side lid and the side plate are engaged with each other via this engaging portion, and the opening can be closed. Moreover, in a state where the opening is closed by the side cover, both the upper member and the lower member of the side cover are engaged with the side plates on both sides of the opening via the engaging portions, so that the strength at the opening is reduced. The advantage of less is achieved.

In the present invention, the hinge of the side lid may be a valley-foldable hinge when viewed from the outside of the container.
Alternatively, a mountain-foldable hinge may be used, but a valley-foldable hinge is advantageous in order to prevent the upper member of the side cover from hanging freely when the side cover is opened. That is, by making the side lid upper member and the lower member valley-folded, free movement of the upper member is regulated by the lower member and the side plate, and the upper member does not hang down.
In addition, in the folding container, the long side plate is provided so as to be able to valley fold via a hinge. Thus, the entire side plate can be folded while the side cover is engaged with the side plate.

In the present invention, the long hole provided in the side lid lower member is
It should have an upward withdrawal dimension sufficient to release the engaged state of the engaging portion between the side lid and the side plate.

In the container according to the present invention, the upper member and the lower member are provided so as to be foldable via a hinge. Therefore, only the upper member of the side lids is provided depending on the type of the article and the storage state of the article. Can be opened, or the entire side lid can be folded open.

In order to perform the former opening, the side cover is pulled out upward to release the engagement between the upper member and the corresponding side plate.
By maintaining the engagement state between the lower member and the corresponding side plate,
The upper member is pivoted forward about the hinge, and the opening can be made only by the upper member.

[0017] Even when the latter opening is performed, the folded side lid can be kept hanging downward,
It can also be in a state of extending substantially horizontally. In any of these cases, since the side lid is folded, there is no hindrance to the operation of taking out and storing items from the opening, and even in the stacked state, it is possible to take out items from the lower container. There is an advantage that it is easily performed.

In the case of a hanging opening, the link preferably has a draw-out dimension sufficient to allow the folded side lid to hang down. That is, in this hanging state, the link is in a state of being rotated substantially horizontally and forward, but in this state, the upper member of the side cover is stored between the lower member of the side cover and the side plate. Space needs to be left.

Further, in the case of a horizontal opening, by providing a concave portion for receiving the upper end portion of the folded side lid upper member in the side plate below the opening, the folded side plate is kept substantially horizontal. can do. According to this aspect, in the container in the stacked state, it becomes easy to open and remove the storage items from the container below the container in which the opening is already open.

The engagement portion used in the present invention comprises a downward receiving member provided on the side plate on both sides of the opening and a locking piece provided on the side cover, so that the structure of the engagement portion is the simplest. However, it is desirable to ensure that the engagement between the two is secure and strong, while keeping the structure simple. That is, by inserting the locking piece of the side cover into the receiver from above, the locking state is ensured. By removing the locking piece from the receiver, the locking can be released.

[0021] In the container of the present invention, it is preferable to provide a bendable finger insertion portion for gripping the side lid, which is partitioned through the cut-out portion, on the side plate above the opening.
With this configuration, gripping the upper edge of the side lid by inserting a finger,
It is easy to pull out the side lid upward, and when the side lid is closed, it is possible to minimize the useless opening area of the side plate, so that dust and the like can enter the inside of the container. This can be effectively prevented.

According to the present invention, there is provided an upper frame, a bottom wall, a pair of opposed side walls whose ends are pivotally attached to the upper frame and the bottom wall and can be bent at the center, and an upper end pivotally pivotally connected to the upper frame. It can be applied particularly advantageously to a folding container consisting of a pair of fitted second side walls. As already pointed out, since the side cover is foldable and the upper and lower members of the side cover are engaged with the corresponding side plates, the entire side plate is folded while the side cover is engaged with the side plate. This makes it unnecessary to perform any special operation when folding.

The opening and closing operation of the opening of the container of the present invention is performed as follows. In a state where the opening is closed by the side lid, the second shaft is located below the long hole, but since the side lid can be lifted upward by the size of the long hole, first, Pull out the side cover upward. Thereby, the engagement between the upper and lower members of the side lid and the side plates on both sides of the opening is released. By this disengagement, the upper member and the lower member of the side cover can be folded via the hinge between them, and the side cover can be rotated around the first axis. In the folded state, it is rotated toward the operator. To fix the open side lid, the folded side lid may be hung downward from the link, or the upper edge of the upper member of the side plate may be formed in a concave portion of the side plate, and may be extended substantially horizontally. Done. In this state, articles are taken in and out through the opening of the side plate. When the loading and unloading of the article is completed, the folded side plate is rotated in the opposite direction to the above, and the side cover upper member and the lower member are straightened, and the side cover is pulled out upward, and the upper member of the side cover is pulled out. The lower member and the side plates on both sides of the opening are locked by the engaging portion, and the opening is closed by the side lid.

According to the present invention described above, it is possible to perform an opening operation on a part of the side cover and an opening operation when the entire side cover is in a folded state. The opening state can be selected accordingly, and the operation of taking out and storing the contents from the opening can be easily performed even in the stacked state, and the locking operation on the side wall of the side cover is also manufactured separately. Without using a special lock mechanism,
The opening is reinforced easily by the engagement between the side cover and the side plate, and as a result, there is an advantage that the reduction in the strength of the opening is suppressed to a low level.
