Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container frame and a container using the same. More specifically, for example, it is suitable for transporting and storing fluid solids such as fruits and fish, and can be easily assembled and folded, and occupies a small space when transported or stored when not used as a container. And improved space efficiency.

[0002]

2. Description of the Related Art For example, when a harvested product such as a fruit is transported from a harvested place to a market or a warehouse in a farmhouse, conventionally, a plastic container having a rectangular external shape in plan view and a rectangular shape in side view is used. Was. This container can be stacked and its capacity is set to about several tens kg so that a person can handle it without difficulty. However, since the capacity is not so large, when transporting harvested products such as fruits in large quantities, the work is troublesome and it cannot be said that the efficiency is high.

In order to cope with this problem, in recent years, as means for transporting and storing articles as described above,
A container having a structure in which a deformable bag (container bag) is housed inside a frame having sufficient strength has come to be used. An example of such a container is disclosed in Japanese Utility Model Laid-Open No. 6-85227. The container disclosed in this publication includes a bottom plate into which a fork of a forklift can be inserted, and a frame framed on the upper portion thereof, and a bag body is accommodated in this frame for use. Further, according to this, a container having a sufficient capacity suitable for transporting and storing articles can be formed relatively lightweight.

[0004]

However, the conventional container disclosed in the above publication has the following problems. That is, the frame of the container cannot be disassembled or folded because the rod-shaped member is firmly fixed by welding or the like. For this reason, conventional containers must always be handled with the frame assembled, and there is no problem when they are used for transporting or storing articles, but when they are not used, they have substantially the same volume. Will be occupied. In this case, for example, when transporting empty containers to a farm or the like, it is difficult to transport many containers at once by truck or the like, and when storing unused containers, the space is wasted and the efficiency is low.

(Object of the present invention) The present invention solves the above-mentioned problems, and can easily assemble and fold a frame body. For example, when carrying an empty state without using it as a container, fold and carry a large number. It is an object of the present invention to provide a container frame having excellent space efficiency and a container using the container frame, for example, such that the container frame can be folded and stored efficiently when not in use.

[0006]

Means of the present invention taken to achieve the above object are as follows. According to the first invention, there is provided a container frame, a main frame provided to face each other, a connection frame connecting both sides of the main frame so as to be rotatable with each other, and a connection with the main frame. Means for fixing the frame at a predetermined angle and releasing the fixing, and by assembling and folding the main frame and the connection frame at a predetermined angle and releasing the fixing, It is a container frame characterized by the following.

In the second invention, the means for fixing the main frame and the connecting frame at a predetermined angle and releasing the fixing means includes an insertion portion provided on the main frame and an insertion portion provided on the connection frame. And an insert that can be inserted into and removed from each of the insertion portions, and each of the insertion portions has an axial direction on the same axis when the main frame and the connection frame are substantially perpendicular to each other. That the main frame and the connection frame are fixed substantially at right angles by inserting the insert into the respective insertion portions whose axial directions are on the same axis. A container frame according to the first aspect, characterized by the following.

In the third invention, the main frame and the connecting frame are
A container frame according to the first or second aspect of the present invention, wherein an attachment portion for attaching a bag is provided.

According to a fourth aspect of the present invention, there is provided the container frame according to the first, second, or third aspect, and a bag detachably provided on the container frame. It is a container characterized by the above-mentioned.

The structure of the frame is not particularly limited as long as it has sufficient strength. For example, the frame may be a rod-shaped body formed into a required shape, a plate-shaped body or the like. In addition, as the material of the frame, a metal such as iron, aluminum, and stainless steel is usually used, but other materials such as plastic can be used if the strength is sufficient.

The means for fixing the main frame and the connecting frame at a predetermined angle and releasing the fixing is not particularly limited, but the insertion portions provided on the main frame and the connecting frame are aligned with the same direction. In addition to fixing the main frame and the connection frame by inserting the insertion body as described in (1) above, it is also possible to adopt a structure in which a removable supporting rod is provided between the main frame and the connection frame.

The material of the bag is not particularly limited as long as it has sufficient strength and deformability and can flexibly correspond to the shape and form of the article to be accommodated. For example, plant fibers such as hemp and cotton, chemical fibers such as nylon and aramid fibers, and composites thereof are employed. The form of the bag is not particularly limited, and for example, a sheet-like form, a net-like form, or the like is adopted.
It is appropriately selected according to the shape and form of the article to be stored.

(Operation) According to the container of the present invention,
When the container is not used, the container frame can be folded. That is, the main frame and the connection frame can be rotated by releasing the fixing of the main frame and the connection frame at a predetermined angle, which constitute the container frame, so that the adjacent main frame and the connection frame can be connected to each other. It can be folded flat so that it abuts.

Therefore, when the container is transported in an empty state, the space occupied by each container can be reduced by folding the container frame, so that many containers can be transported, for example, by truck. Also, when storing unused containers, folding the container frame in the same way reduces the occupied space,
It can be stored efficiently. Thus, according to the present invention, it is possible to provide a container frame excellent in space efficiency and a container using the same.

Means for fixing the main frame and the connection frame at a predetermined angle and releasing the fixation include an insertion portion provided on the main frame, an insertion portion provided on the connection frame, and an insertion / removal portion for each insertion portion. Each insertion portion is provided so that the axial direction is on the same axis when the main frame and the connection frame are substantially at a right angle, and the insert is inserted in the axial direction. The main frame and the connecting frame are fixed at a substantially right angle by inserting them into the respective insertion parts on the same axis. The container frame can be assembled by fixing the frame and the connection frame, and can be folded by releasing the fixing. Therefore, it is possible to quickly assemble and fold the container, thereby improving work efficiency.
