2. Description of the Related Art There are various types of containers for storing and transporting articles, but generally, a rectangular parallelepiped container in which a grid-like panel made of steel and a floor are assembled is used. Such a container needs to have sufficient strength because it is often used for accommodating and transporting articles, and is also stacked while accommodating. Furthermore, since it is often carried empty and must be stored in a warehouse when not in use, it is desirable to be able to fold it compactly. Various foldable containers have been proposed as described below.

(1) A planar object carrier in which the lower portion of the side frame is rotatably fixed to the floor surface and is foldable (Japanese Patent Laid-Open No. 4-114864).

A storage pallet that can be used (see Japanese Patent Application Laid-Open No. 717542).

On a large-scale farm, agricultural products such as rice and wheat harvested with combine are threshed on the spot, and only the fruits (rice and wheat) cut from the ears are stored in containers and stored in facilities such as warehouses. Be transported. Such containers are often rotated in the air with a forklift while containing the crops to take out the crops from the upper opening, and are often stacked while containing the crops. As such a container, (4) A foldable type with a small protruding amount at the lower end of the folded panel and no gap between the lower end and the floor when the panel is raised and there is no risk of damage to the support pins. A container has been proposed (Japanese Patent Laid-Open No. 2000-109069,
reference).

[0005]

None of the containers (1) to (3) described above has a structure in which the fork of a forklift can be inserted and rotated. Also, the container of (4) can rotate but only the side frame can be folded.

A first object of the present invention is a container that can be stacked in an assembled state, can be folded when not in use, can be stacked in a folded state, and can be loaded and unloaded from the side. The second purpose is to be capable of stacking in an assembled state, folding when not in use, and stacking in a folded state, and further rotating with a forklift to provide articles. It is to provide a container that can take out.

II. Regarding the container of the second invention: Fig. 24
[Fig. 6] is a conceptual view showing a state where the container of the second invention is assembled, (a) is a plan view, (b) is a side view, and (c) is a front view.

In the container of the second invention, as shown in FIG. 24, four guards (front guard 18, rear guard 19, left side guard 20, right side guard 21) are erected on the four circumferences of the floor 17 so that the upper part It has an open rectangular parallelepiped structure. 4 guards 18-21
Is a lattice structure composed of vertical and horizontal beams and crosspieces made of steel. This is because when the agricultural products are stored, the ventilation is ensured and the deterioration of the quality of the agricultural products is prevented. A storage bag for storing rice and wheat is inserted inside the container. The floor 17 is provided with an insertion opening 7 into which a fork of a forklift is inserted, and the fork can be inserted into the insertion opening to rotate the container and the contents can be taken out from the upper opening.

The four guards 18-21 are their lower transverse beams.
18-1, 19-1, 20-1, 21-1 are pivotally supported on four circumferences of the floor body 17 by four pivot members 22 to 25 having different axial center heights.
It can rotate around 18-1, 19-1, 20-1, 21-1. When the guards 18-21 are assembled, the front and rear guards
The heights of 18, 19 and the heights of the side guards 20, 21 are equal to each other, and the side guards are higher than the front and rear guards.

The front and rear surface guards 18, 19 and the side surface guards 20, 21 are connected by two connecting members 30 and 31 at the same height at the four corners.

The connecting member 30 is the vertical beam 1 of the front and rear guards 18, 19.
It is inserted through 8-2 and 19-2 so that it can rotate and move in the longitudinal (up and down) direction. The connecting member 31 is a side guard.
The vertical beams 20-2 and 21-2 of 20, 21 are inserted so as to be rotatable and movable in the longitudinal (vertical) direction. The connecting member 30 is shown in FIG.
When connected to the connecting member 31 as shown in (c), the upper sides of the side surface guards 20 and 21 become wider toward the outside (opening upward).
The structure is such that they are inclined and connected. As a result, the center-to-center distance W ₁ between the upper lateral beams 20-3 and 21-3 of the side surface guards 20 and 21 is the center-to-center distance W ₃ between the left and right rails 6 of the floor body 17.
