Description

  The present invention relates to a container formed of a metal material, and more particularly to a container that can increase the strength of a connecting portion and ensure the overall strength even when manufactured with a relatively thin metal plate material.

  It is preferable that a container for storing and transporting various kinds of luggage is assembled immediately before use, disassembled after use, and discarded or reused.

  Patent Document 1 describes an invention related to a container that is assembled from container materials and can be disassembled after use.

  In this container, connecting members are attached to a plurality of sides of a plastic square pallet, and lower portions of the side structures covering the four side surfaces of the pallet are fixed to the pallet by the connecting members. Each side structure has an upper frame and a lower frame, and two side vertical frames and a central vertical frame. Two inclined frames are fixed between each side vertical frame and the central vertical frame.

  The connecting member is formed of a metal plate, and has an upward support surface, an upper holding plate portion folded from the upward support surface on the outer surface side of the side structure, and an upwardly rising upright from the upward support surface on the inner surface side. The plate portion is integrally formed. The lower frame of the side structure is formed of an L-shaped metal plate and has a horizontal plate portion and a vertical plate portion. By sandwiching the horizontal plate portion of the lower frame between the upward support surface of the connecting member and the upper holding plate portion, the vertical plate portion abuts against the inner surface of the upward plate portion of the connecting member, so that the side structure becomes a pallet. Built-in to stand up vertically.

  At the four corners of the upper part of the container, the side vertical frames of the adjacent side structures are combined, and the ends of the adjacent side structures are connected by the upper connection fitting.

JP 2013-159353 A

  In the container described in Patent Document 1, the pallet is made of a thick plastic material, and the bottom portion has high rigidity. Furthermore, if a plurality of frames, connecting members, and the like constituting the side structure are formed of a thick metal plate, the rigidity of the entire container can be increased, and the connecting portion between the pallet and the side structure or the side structure It is possible to make the connection strength of the connection parts relatively high.

  However, to reduce the weight and reduce costs, if the bottom structure, side structure, and connecting member that replaces the pallet are formed of a relatively thin metal plate, the overall rigidity of the container should be avoided. I can't.

  In a container with low rigidity, as described in Patent Document 1, in a structure in which the side vertical frame of the adjacent side structure is simply pressed from above by the upper connecting bracket, the side vertical of the adjacent side structure is vertical. It is not possible to ensure sufficient connection strength against the relative positional deviation between the frames in the vertical direction. For example, in an operation where a container is lifted and moved by a forklift, if the rigidity of the container is low, the entire container is distorted, and the side vertical frames of adjacent side structures are relatively moved up and down. It becomes easy to shift. At this time, there is a possibility that the upper coupling fitting may come off.

  In addition, when the lower frame of the side structure is formed of a thin metal plate, the strength at the connecting portion between the lower frame and the connecting member is likely to decrease. In this case as well, if the central part of the container is lifted by a forklift or the like and the entire container is distorted, the lower frame is easily deformed, and the horizontal plate part of the lower frame holds the upper support surface and the upper side of the connecting member. Problems such as detachment from between the plate portions are likely to occur.

  The present invention solves the above-described conventional problems, and can increase the connection strength at the connection portion between the side structure bodies and the connection portion between the bottom structure body and the side structure structure, and is relatively rigid. An object of the present invention is to provide a container that can ensure connection strength even when a low material is used.

An inner plate portion extending downward from the plate portion,
The upper plate portion of the upper stile of the second side structure is inserted into the gap, the outer plate portion is positioned outside the support column of the first side structure, and the inner plate portion is the It can be configured as being inserted into the opening.

The container of the present invention includes an upper plate portion provided on the first side structure, an upper plate portion, and an outer plate portion extending downward from the upper plate portion on the outer surface side of the first side structure. An inner plate portion extending downward from the upper plate portion on the inner surface side,
A partial notch is formed in the inner plate portion, and the upper stake of the second side structure passes through the notch and is inserted into the gap.

Furthermore, the container of the present invention is provided with an upper connecting bracket having at least two insertion pieces,
The insertion piece is inserted into the slit formed in the upper sill of the first side structure and the slit formed in the upper sill of the two side structure, respectively, and the first side structure The body and the second side structure are connected by the upper connection fitting.

The container of the present invention is provided with a bottom connecting portion on the side portion of the bottom structure, and the bottom connecting portion includes a bottom plate portion, a support plate portion rising from the bottom plate portion outside the bottom structure, and A support claw portion extending inward from the support plate portion,

The lower plate portion of the lower stake is installed on the upper surface of the bottom plate portion of the bottom connecting portion, the side plate portion is installed on the inner surface of the support plate portion, and the support claw portion is inserted into the slit. Is preferred.

  In the container of the present invention, the lower stile can be formed of a metal plate that is thinner than the bottom connection fitting.

  In the container of the present invention, the upper stile of the other side structure is sandwiched in the gap between the end of the column of the one side structure and the upper stake in the connecting portion of the side structure. As a result, the connection strength between the side structures at the upper corners of the container can be increased. For example, even if the container is made of a thin metal plate and the entire container is easily distorted, the adjacent side structures are not It is possible to restrict relative displacement in the vertical direction.

  Also, a bottom plate portion, a support plate portion rising from the bottom plate portion, and a support claw portion extending inward from the support plate portion are formed on the bottom connection portion provided in the bottom structure, and the support claw is connected to the side portion. By inserting the slit into the slit formed in the side plate portion of the lower stile of the structure, the connection strength between the bottom linking portion and the lower scab can be increased.
