DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a structure for attaching a side lid to a container in which stored items can be taken in and taken out from the side of the container in a stacked state.

[Background technology] Containers that allow stored items to be taken in and out from the side of the container in a stacked state have been developed since 1983.
It is known from Publication No. 47069. In this conventional example, as shown in FIG. 9, a side opening 2 is provided at the side of the container 1, and a lower bearing portion 4 is provided at the lower end of both left and right edges of the side opening 2. , a lid-side bearing part 8 is provided at the lower end of both left and right edges of the side lid 7, the lid-side bearing part 8 is rotatably attached to the lower bearing part 4 by a shaft 10, and the side lid 7 is mounted around the shaft 10. The container 1 is rotated to open the side opening 2, and items stored in the container 1 can be put in and taken out. However, in the above conventional example, since the lid side bearing part 8 and the lower bearing part 4 of the side lid 7 are directly supported by the shaft 10, the side lid 7 is rotated at 90 degrees as shown in FIG. I could only open it. However, when containers are stacked,
If the side lid 7 can only open 90 degrees, the side lid 7 will get in the way of taking things in and out of the container 1 through the side opening 2 on the side of the container 1 (especially when the top The more containers 1 are stacked, the more the side lids 7 get in the way, making it difficult to take them in and out. There was a problem that the shaft support part of 7 was easily damaged. Therefore, it may be possible to install a link mechanism or the like to open the side lid 180 degrees, but in the case of a container located at the bottom, if the side lid opens more than 90 degrees, it will hit the floor and the side lid will open 180 degrees. A new problem arises: the side lid gets scratched, and dirt from the floor gets stuck to the side lid, making it unsightly.

[Object of the Invention] The present invention was invented in view of the above-mentioned conventional problems, and its purpose is to open the side lid 180 degrees and open the side cover 180 degrees when taking out or putting in stored items. A side lid of a container that allows the lid to not get in the way of putting things in and out of the container through the side opening, and also allows the side lid to be held at an open angle of 90° if necessary. to provide the mounting structure.

[Disclosure of the Invention] The attachment structure of the side lid of the container according to the present invention includes the container 1
A side opening 2 is provided on the side of the side opening 2.
In a device in which a side lid 7 for opening and closing is rotatably attached, the side lid 7 of the container 1 is opened to the side of the side opening 2 and to the outside of the container 1 at the lower part of the left and right edges of the side opening 2 of the container 1, respectively. A groove portion 24 having a substantially L-shaped shape when viewed from the outside is provided, and lower bearing portions 4 are provided on both sides of the upper portion of this groove portion 24, and an L-shaped portion is disposed within the groove portion 24.
The upper end portion of the vertical piece portion 18a of the link portion 18 having a shape is pivoted to the lower bearing portions 4 on both upper sides of the groove portion 24 by a shaft 10a, and the horizontal piece portion 18b of the link portion 18 and the lower side end portion of the side cover 7 are connected to each other. is pivotally supported by a shaft 10b, and the side cover 7
A notch 23 that opens at least forwardly and downwardly is provided on the outer surface of the lower edge of the
4, the notch part 23 fits into the groove part 2, and the horizontal piece part 18b of the link part 18 fits into the groove part 2.
When the notch part 23 is separated from the inside of the 4 and protruded outward, and the link part 18 is accommodated in the groove part 24, and the side cover is at an opening angle of 90°, the lower surface of the notch part 23 touches and opens at 90°. A holding protrusion 21 for maintaining the opening angle of the container 1 is provided at the lower edge of the side opening 2 of the container 1. By adopting such a structure, the above-mentioned aspect of the present invention can be achieved. The purpose has been achieved. That is, in the present invention, since the lower part of the side cover 7 is rotatably attached to the lower parts of the left and right edges of the side opening 2 via the link part 18, when the side cover 7 is opened, the link part 18 The pivoting portion of the side cover 7 with the link part 18 can protrude to the outside by the extent that the end of the side protrudes outward, and the side cover 7 can be opened without being obstructed by the lower edge of the side opening 2. omitted
It can be opened 180 degrees, and when the side cover is opened 90 degrees with the link part 18 housed in the groove 24, the lower surface of the notch 23 hits the holding protrusion 21 and opens 90 degrees.
This makes it possible to maintain the opening angle.

The present invention will be explained in detail below with reference to Examples. The container 1 is open at the top and sides. Here, the container 1 may be a non-folding container or a folding container. The side opening 2 of the container 1 is provided with lower bearing portions 4 at the lower portions of both left and right edges. That is, a substantially L-shaped groove 24 that opens toward the side opening 2 and to the outside of the container 1 is provided at the bottom of the left and right sides of the side opening 2 of the container 1. A bearing portion 4 is provided. An L-shaped link part 18 consisting of a vertical piece part 18a and a horizontal piece part 18b is arranged in the groove part 24, and a hole 19a provided in the vertical piece part 18a is inserted into the upper end of the vertical piece part 18a of the link part 18. Using the lower bearing part 4 of the container 1
are rotatably connected to each other by a shaft 10a. The horizontal piece 18 of the link part 18 is rotatably connected to the lid-side bearing part 8 provided in the side lid 7 by a shaft 10b using a hole 19b provided through the horizontal piece 18b. However, when the side cover 7 is opened, the link part 18
The horizontal piece 18b protrudes outward beyond the lower edge of the side opening 2, allowing the side lid 7 to be rotated 180° without being obstructed by the lower edge of the side opening 2, as shown in FIG. It can be rotated to open. When the side cover 7 is opened 180 degrees downward in this way, the side cover 7 is opened to the second position.
As shown in the figure, since it is approximately vertical, the side lid 7 does not get in the way when putting things in and out of the side opening 2, and when the side lid 7 opens only 90 degrees, When loading and unloading, there is no chance that the stored items will be placed on the side lid 7 and the weight of the stored items will damage the side lid 7 or the pivot portion of the side lid 7. If a second lower bearing part 4a is provided below the lower bearing part 4 of the container 1, a shaft 10c having a longer length than the shaft 10b can be connected to the second lower bearing part 4a instead of the shaft 10b. The long shaft 10 is inserted into the lid side bearing part 8 through the hole 19b of the link part 18, and the lid side bearing part 4 is inserted into the second lower bearing part 4a through the link part 18.
It is also possible to attach it rotatably by c. In this case, the side cover 7 can be rotated 90 degrees to open downward. Note that a protrusion 20 for preventing lateral slippage and a retaining protrusion 21 for maintaining an opening angle of 90° protrude from the lower edge of the side opening 2.
When the side cover 7 is opened 90 degrees, the side slip prevention protrusion 20 fits into the recess 22 provided on the outer surface of the lower edge of the side cover 7, and even if the side wall 7 tries to move laterally, the side slip prevention protrusion 2
0 comes into contact with the inner wall of the recess 2, and lateral displacement is prevented. Furthermore, when the side cover 7 is opened 90°, the lower surface of the notch 23 provided on the outer surface of the lower surface of the side cover 7 hits the holding protrusion 21 to maintain the 90° opening angle of the side cover 7. It's becoming like that. By the way, both the recessed part 22 and the cutout part 23 are open at the bottom, and therefore, when the link part 18 is used to allow the side cover 7 to rotate 180 degrees, the link part 18 is opened. When the lower part protrudes outward, the lower end of the side cover 7 also protrudes outward, so that the lateral slip prevention protrusion 20 and the holding protrusion 21 can come out from the lower opening of the recess 22 and cutout 23. Become. Further, a locked portion 5 consisting of a hole opening downward is provided at the upper edge of the side opening 2. Side lid 7
A locking portion 9 is provided on the upper edge of the holder. This lock portion 9 has a structure as shown in FIG. 5, for example. That is, a guide groove 11 that opens upward is provided at the upper edge of the side lid 7, and a sliding body 12 having a protrusion 16 is slidably fitted into the guide groove 11, and the sliding body is held by an elastic body such as a spring material 13. 12 is given an upward elastic biasing force. An operating section 17 projects outward from the center of the sliding body 12. Further, the sliding body 12 is provided with a stopper 14, and the stopper 14 is provided in a long hole 15 provided in the side cover 7.
is slidably fitted into the slide body 12, and when the stopper 14 hits the edge of the elongated hole 15, the protrusion 16 provided on the slide body 12, which is elastically biased upward by the spring material 13, protrudes beyond a certain level. I've learned not to. The protruding portion 16 is locked into a hole which is the locked portion 5. By pinching the operating part 17 and pulling it downward, the sliding body 12 is moved and the protruding part 16 provided on the locking part 9 is detached from the locked part 5.

In the embodiment shown in the drawings, an upper shaft bearing part 3 is provided at the upper part of both left and right edges of the side opening 2 of the container 1, and when the side lid 7 is desired to open upward, the link part 1 is provided.
The lid-side bearing part 8 of the side lid 7 can be rotatably attached to the upper bearing part 3 by a shaft by turning the side lid 7 upside down without having to pivotally support the side lid 7 on the upper bearing part 3. In this way, the side cover 7 can be opened upward. In this case, if the locked part 6 is also provided at the lower edge of the side opening 2 of the container 1, the locking part 9 can be freely engaged and detached from the locked part 6 even when the side lid 7 is attached to open upward. It can be locked to.

[Effects of the Invention] As described above, in the present invention, both lower portions of the side lid are rotatably attached to the lower portions of the left and right edges of the side opening of the container via link portions, respectively. When opening the side cover, the pivot portion of the side cover with the link can protrude to the outside by the extent that the end of the link protrudes outside, without being obstructed by the lower edge of the side opening. The side cover can be opened approximately 180 degrees, and a notch that opens at least forward and downward is provided on the outer surface of the lower edge of the side cover, and the link part can be cut out with the link part accommodated in the groove. When the notch fits in and the horizontal piece of the link part protrudes from inside the groove, the notch part separates, and the link part fits into the groove and the side cover opens at a 90° opening angle. A retaining protrusion is provided at the lower edge of the side opening of the container so that the lower surface of the link rests against the opening angle of 90°. When the lid is opened 90°, the lower surface of the notch hits the holding protrusion, making it possible to maintain the 90° opening angle.As a result, in the case of the present invention, containers can be stacked. if you did this,
For example, containers stacked on top can be opened 180 degrees to allow storage and removal of stored items without being obstructed by the side lids, while containers stacked on the bottom can be held with their side lids open 90 degrees to allow storage. This prevents the lid from being scratched or soiled by hitting the floor. In addition, grooves having a substantially L-shaped shape when viewed from the outside of the container are provided at the lower portions of the left and right edges of the side opening of the container, opening toward the side opening and toward the outside of the container, respectively. Lower bearing parts are provided on both sides of the upper part of the container, and the upper end of the vertical piece of the L-shaped link part disposed in the groove is pivoted by a shaft to the lower bearing parts on both sides of the upper part of the groove. Although the side lid can be fitted into the side opening and opened by rotating 180 degrees, both sides of the vertical piece of the link cannot be supported from both sides by the lower bearings on both sides of the groove. The link part can be stably and firmly pivoted to the container, and the pivot part of the link part to the container will not be twisted by the weight of the side lid.
