Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a pallet in which four surrounding frames standing around a pedestal on which luggage is placed can be detached and folded.

<Prior art> In recent years, when a large amount of automobile parts are exported due to the modernization of physical distribution, for example, the spread of container ships and the mechanization of cargo handling, it is often the case that a pallet with a surrounding frame is used. . In the recent loading of the pallets, the pallets are often arranged on a conveyor, and while the pallets are moved in the left-right direction, the loads specified for each destination are sequentially loaded. In this case, the space between the pallets on the conveyor is reduced as much as possible to improve the space efficiency.To this end, the front and rear door frames of the enclosure that are opened for loading cargo are placed outside the side frames. It is desirable to be able to fold along.

In addition, it is good in terms of space cost to fold the empty pallet after delivering the luggage to the destination and send it back to the shipping source, but in this way it is possible to fold the surrounding frame around the pedestal on which the luggage is placed. As the pallet, for example, the actual Kaisho 51-13
Some are disclosed in Japanese Patent No. 9139.

The pallet disclosed in the above-mentioned Japanese Utility Model Publication is configured such that left and right side frames (3A, 3B) detachably attached to both left and right sides of the upper surface of the pallet (1) can be folded onto the pallet (1). The front and rear frames (4A, 4B) located on both front and rear sides of the upper surface of the pallet (1) are replaced by the left and right side frames (3A, 3B).
The front and rear frames (4A, 4B) between the front and rear frames (4A, 4B) and the pallet (1). The push-fitting portions (5A, 5B) are configured to prevent the rotation by extending and lowering the rotation to a predetermined position.
(Numbers and symbols in parentheses are those used in the above-mentioned Japanese Utility Model Publication.) <Problems to be solved by the invention> However, in the pallet disclosed in the above-mentioned Japanese Utility Model Publication, side frames (3A, 3B) are used. Both end members have a short section, and the front and rear frames (4A, 4B) made of round pipes are attached to the members by hinges oriented in the left and right direction of the pallet (1). ) Can be rotated only toward the inside of the pallet (1), and when the pallets are packed and arranged on the conveyor as described above, the front and rear frames (4A, 4B) are arranged in an open state. Not only dangerous, but also the front and rear frames (4A, 4B) of the pallet to avoid the above danger.
