[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a container that can be loaded and unloaded onto a gear rear while maintaining a horizontal attitude. There is the following (Japanese Patent Application Laid-Open No. 52-57615). This container cargo handling vehicle consists of a container that has a bendable cargo handling arm provided on the body of a carrier and a locking portion at the upper end of the front portion that is engaged with a hook at the tip of the cargo handling arm. When loading a container onto the gear rear, the hook at the tip of the cargo handling arm hooks the locking section at the front of the container to pull the container diagonally up onto the vehicle body. Furthermore, when loading or unloading a container, the cargo handling arm is used to lower the container diagonally to the ground.

<Problems to be Solved by the Invention> However, with the container of the conventional container handling vehicle mentioned above, when loading and unloading the container onto the carrier, the container is oriented diagonally, so there are no pianos, furniture, etc.
There was a problem in that it was not possible to load fragile items, and the items that could be stored in these containers were limited to garbage and waste.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a container that can be loaded and unloaded onto a carrier while maintaining a horizontal position, and can therefore be loaded with pianos and other fragile furniture.

<Means for Solving the Problems> In order to achieve the above object, the container of the present invention includes a support member that is installed at the rear of the container body and that can be raised freely;
A connecting member fixed to the front part of the container body and removably connected to the carrier, and a movable part QF and a movable part QF, which is movably provided at the front part of the container body and removably connected to the carrier 2. A means for transmitting the movement of the member to the support member to raise and lower the support member is provided, the movable member is held at a constant height, and when the connecting member is lifted, the container body is held approximately horizontally. It is characterized by the fact that it can be raised.

Further, it is preferable to provide the lower end of the support member described in 2 above with, for example, a roller or a grounding member that is immovably in contact with the ground.

<Function> When loading a container onto a carrier, the front of the container is lifted by lifting the connecting member at the front of the container body using means on the carrier side, and the movable member at the front of the container is moved from the ground. 2, and the relative movement of this movable member with respect to the container body is transmitted to the support member at the rear of the container by a transmission means to cause the support member at the rear of the container to protrude downward to lift the rear part of the container, and to move the front part of the container body. and rear parts synchronized with each other and raised horizontally. When the height of the container and the height of the vehicle body become the same, the container is advanced onto the gear rear vehicle body by, for example, pulling the connecting portion forward and supporting the rear part of the container against the ground by the support member. Thereafter, the movable member is actuated, for example, by the movable member drive means on the gear rear side, and the support member is lifted up from the ground. Furthermore, when lowering the container to the ground, the container can be lowered to the ground while maintaining a horizontal position by performing an operation opposite to the oil-based operation.

In addition, when the container is raised to the same height as the vehicle body = 3 or more, the carrier may be moved backward without pulling the connecting member forward, and the container may be mounted on the vehicle body.

Further, instead of operating the movable member to lift the support member from the ground, the support member may be bent and fixed so that the support member does not support the ground.

The lower support member 302 is fixed downward with a lock pin 304. In addition, as shown in FIG. 11, when bending the lower support member 302 forward, the lock pin 304 is removed in FIG.
When the lower support member 302 is inserted, the lower support member 302 is fixed in the rearward direction. In this embodiment, there is no need to operate the movable member to pull up the support member, so the carrier-side movable member does not need to be raised or lowered, and may be fixed to the column, and no carrier-side movable member driving means is required. Furthermore, the container's chain 7IO and sprockets 42 and 43 are unnecessary.

Incidentally, in this embodiment, the support member has a bending structure, but the structure is not limited to this, and the same effect can be obtained as long as the support member can be separated from the ground by itself.

<Effects of the Invention> As is clear from the above, the container of the present invention includes a support member that can be raised and lowered at the rear of the container body, a connecting member and a movable member at the front of the container body, and the operation of the movable member. By providing a transmission means for transmitting this to the support member, the front part of the container can be moved up and down by the connecting member, the movable member is fixed to the ground, and the movement of the movable member relative to the container body can be transmitted through the transmission means. This is transmitted to the support member to lower the support member by 1 and move the rear part of the container 2 to lower, so the 2 lower movement of the connecting member and the movement of the support member are synchronized and the container is leveled. The carrier can be loaded and unloaded while maintaining its orientation, and therefore pianos, fragile items, etc. can be transported with a simple and inexpensive configuration.

Furthermore, in the container of the present invention, the support member for vertically moving and supporting the rear part of the container is operated by the movable member at the front part of the container, so the drive system is installed on the gear rear side. There is no need to provide the container with any driving means, and the container can be constructed at low cost.

In addition, since the container of the present invention transmits the driving force of the gear rear to the container through the connecting member and the movable member at the front of the container, the container can easily move downwards while maintaining its horizontal position. It can also be easily moved back and forth.
