BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a box pallet which is capable of accommodating various articles such as industrial wastes therein and which permits the articles to be taken out therefrom.
BACKGROUND OF THE INVENTION
Conventionally, this type of box pallet is formed in a box-shaped configuration having an open top and is adapted to accommodate suitable articles such as industrial wastes therein. Practically, when the articles such as the industrial wastes are taken out from the interior of the box pallet, since the box pallet containing the articles such as the industrial wastes is a considerably heavy object, the box pallet itself is hung up by a lifting device such as a fork lift truck and is conveyed to a predetermined place. Thereafter, the box pallet itself is in turn hung up by another means such as wires, so that the box pallet is tilted for taking out the articles from the open upper portion.
Further, a different type of box pallet has been proposed to provide a construction in which a part of a side plate or a bottom plate of the box pallet is opened and closed, so that articles such as industrial wastes can be relatively easily taken out.
However, with the above conventional construction, during the operation for taking up the accommodated articles such as the industrial wastes, the box pallet itself is in turn hung up by separate means such as wires so as to be tilted. Therefore, the operation requires at least two operators, one for actually making the change to hang up the box pallet by wires, and another for operation of hanging up the box pallet by lifting device such as a fork lift truck. If a cooperating operation of the operators is hindered, the operation for making the hanging-up change of the box pallet becomes very dangerous, and in some cases, the operators may be seriously injured by corners of the box pallet or the wires.
Additionally, with the type in which the slide plate is opened and closed, after the side plate has been opened, the operator must perform a very troublesome operation for taking out the articles such as the industrial wastes accommodated within the box pallet. In order to take out the articles at a time, the box pallet itself must be hung up as described above, so that the operator cannot get out of possible danger during the operation.
Further, with the type in which the bottom plate is opened and closed, although this measure may solve the above problems, the opening and closing construction may be large-scaled, so that this type is not suited for practical use.
DISCLOSURE OF THE INVENTION
In view of the problems encountered in the prior art, the present invention proposes a box pallet which permits articles such as industrial wastes accommodated within the box pallet to be safely and easily taken out, with a simple construction.
(1) According to a first invention, there is provided a box pallet having an open top, a side plate and a bottom plate for surrounding the box pallet on four sides and a bottom, the bottom plate being divided into two bottom plate parts and being assembled to move in a downward direction for opening and closing, the box pallet comprising an actuation arm vertically pivotally supported by the side plate, an interlocking member provided for interlocking between the actuation arm and the two divided bottom plate parts so as to permit opening and closing movement of each bottom plate part, and an actuation rod horizontally supported such that the actuation rod can change its position between a position on a pivotal locus of the actuation arm and a position out of the pivotal locus and is engageable with and disengageable from the actuation rod, the bottom plate parts being held to be closed when the actuation rod is in engagement with the actuation arm, and the bottom plate parts being permitted to be opened when the actuation rod is in disengagement from the actuation arm.
With this box pallet, on the condition that the box pallet is hung up by lifting device such as a fork lift truck, by moving the actuation rod to
