Description

  The present invention relates to a bodywork placement mechanism for placing a transport object in a commercial (cargo or passenger transport) automobile for transporting various articles.

  For example, in order to accommodate an object to be transported by a cargo vehicle, as shown in FIG. 18, when the placement object placed on the chassis 100 is a container 3, conventionally, the chassis of a cargo vehicle has been used. A tightening device (twist lock) 4 was installed on the 100 side, and the container 3 was fixed by the twist lock 4.

However, in such conventional technology, if the installation position of the male member 41 of the twist lock 4 on the chassis 100 side and the position of the twist lock receiving port (female member) 42 on the container 3 side do not correspond accurately, the container 3 It is dangerous because it is not sufficiently fixed to the chassis 100.
Therefore, there is a problem that the position of the twist lock receiving opening 42 on the container 3 side to be fastened is limited to the position corresponding to the installation position of the male mold 41 of the twist lock 4.
Therefore, the types of containers that can be used for each vehicle type are limited, which limits the capacity of container transportation.

In addition, since a cargo vehicle having a twist lock on the chassis is limited to a container, the cargo to be transported by the cargo vehicle is limited to one that can be accommodated in the container.
In addition, the fact that a vehicle other than a container cannot be used as an object to be placed on a freight car having a twist lock on the chassis can be a factor that hinders improvement in the efficiency of the transportation system using the freight car.

As another conventional technique, a container system having a base plate and a container that is rotatably mounted on the longitudinal axis thereof has been proposed (Patent Document 1).
However, this technology is for placing the same container in different transportation facilities, and does not address the above-mentioned problem of using multiple types of containers and other placement objects on the same truck. Absent.
