Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large assembly container which can be transported by a forklift.

[0002]

2. Description of the Related Art Conventionally, a wooden container has been known as a large-sized container, and when carrying a stored item in a large-sized wooden container, the container has a large capacity and a large weight. Although wooden containers are placed on a pallet and transported by a forklift, the wooden container is not integrated with the pallet, so it is necessary to place it on the pallet and remove it from the pallet, When storing and transporting a large wooden container in an empty state, a large space is required, and for these reasons, there is a problem that the distribution cost and the storage cost increase. In addition, since the container is large enough to put or take things out of a large wooden container, the worker is placed on or in the upper opening edge of the large wooden container. In such a case, it is necessary to carry out the storage and retrieval of the stored items beyond the side plate, which is extremely troublesome and troublesome.

In view of this, the present applicant has arranged side plates on four sides of the upper surface of a pallet, and at the corner where the side plates are adjacent to each other at right angles, a substantially comb-toothed meshing portion provided at the end of one side plate and the other side plate. The substantially comb-shaped meshing portion provided at the end of the side plate is detachably meshed, and the connecting rod is inserted into the connecting hole provided in the meshing portion of the both side plates and the connecting hole provided in the pallet, and screwed with a nut. An application for an assembling container to be performed has been filed as Japanese Utility Model Publication No. 5-16106.

[0004] This device can be easily disassembled by removing the connecting rod, and by disassembling, the transportation cost and the storage cost can be reduced.

[0005] However, in this conventional example, the connection to the pallet by the connecting rod in a state where the substantially comb-like meshing portions of the side plates adjacent at a right angle are engaged with each other, and protruding from the lower surface of each side plate. The four side plates are assembled into a quadrilateral shape by engaging the engaging portions with each other because the mounting configuration is employed in which the fitting protrusion for standing is fitted into the fitting recess formed on the upper surface of each side of the pallet. In this state, unless the procedure of fitting the fitting projection of each side plate to the fitting recess of the pallet is taken, the side plates cannot be built on the four sides of the pallet. In other words, after assembling the three side plates into a U-shape and building them on the three sides of the pallet, even if the remaining one side plate is to be mounted, the engagement between the engaging portions is performed by a horizontal fitting operation. However, the fitting between the fitting projection and the fitting recess is performed in the vertical direction, and it is impossible to perform both at the same time. After being built on the side, the other side plate cannot be attached.

Further, in the above conventional example, after the three side plates are assembled in a U-shape and built on the three sides of the pallet, not only the remaining one side plate cannot be attached, but also Assemble one side plate into a U-shape and build it on the three sides of the pallet, and connect the other one side plate to one end of the side plate assembled and built only in one end with a connecting rod, Even if the other end is released by releasing the connection by the connecting rod, the end of the conventional meshing portion is not shaped so that it can rotate without being disturbed by the end surface of the adjacent side plate. Therefore, it is not possible to adopt a configuration that facilitates taking in and out of stored items by rotating and opening one side plate. In addition, as described above, since the fitting projection and the fitting recess need to be fitted in the vertical direction, the conventional example also turns one side plate to open and turns to close. Cannot be connected with a connecting rod.

For the above-mentioned reason, in the conventional example, one side plate is rotatably used as a side cover so that one side of a large assembly container is opened, and the contents are put in and out of the assembly container through the opening. I couldn't do that.

Therefore, the inventor of the present invention, in the process leading to the present invention, opens the one side of a large assembly container by rotatably using the side plate as a side cover, and puts in / out the articles into the assembly container through the opening. However, in order to make the side plate freely rotatable, only both ends are connected to the pallet by a detachable rotating shaft, and an intermediate portion of the side plate can be rotated with respect to the pallet, that is, a conventional state. In this way, it is not possible to adopt a configuration in which the fitting projection integrally projecting from the lower surface of the side plate is fitted to the fitting concave portion of the pallet. If the intermediate portion of the side plate is pushed by the stored matter and swells outward, there is a possibility that the side plate and the rotating shaft portion may be damaged.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and can be easily disassembled in a large-sized assembly container when not in use to make it compact. In addition, one of the side plates can be rotatably opened with a simple structure during use so that the contents can be easily taken in and out of the assembly container, and the side plates are set up on four sides of the pallet. In the state that the side plate is assembled, the middle part of the side plate can be connected to the pallet with a simple configuration to prevent the side plate from bulging outward and dent inward. An object of the present invention is to provide an assembling container capable of holding a member with a simple configuration and holding a lock member in a unlocked state with a simple configuration.
