[0030]

As described above, according to the transport pallet of the present invention, while being able to be nested in a nesting manner, when used for transporting or storing luggage, the front panel is attached and the entire bottom plate portion is mounted. It can be conveniently used as a box-shaped pallet whose periphery is surrounded by panels. Moreover, the front panel removed prior to nesting
Because it can be supported on the back of the rear panel,
Compared to the case where it is stored in a different place from the pallet body,
The work of mounting the front pallet prior to use of the pallet can be performed easily and efficiently. Further, in the case where a square dish-shaped cup is attached to the upper end of each pillar for stacking, when the nesting is performed, the square dish-shaped cup protrudes from the front face of the rear pillar so that there is a gap between the front and rear adjacent rear pillars. However, according to the configuration of the present invention, the gap can be used as the support space of the front panel from which the space is removed, and the overlap between the upper and lower pallets in the front-rear direction at the time of nesting is reduced, and the number of nesting steps is reduced. Such inconvenience does not occur.

According to the second aspect of the present invention, when the front panel is erected between a pair of left and right front columns or is supported on the rear surface of the rear panel, the front panel is more integral than the one having an integral structure.
Work can be done easily and easily because the lightweight stays can be handled one by one.

According to the third aspect of the present invention, the supports (each stage support portion) protruding from the rear surface of the pair of rear right and left columns are protected by the vertical plate, and other objects are used when the pallet is used. It is possible to reduce the possibility that the support (each stage support portion) comes off or deforms unexpectedly due to contact collision with the support member. Further, it is possible to prevent each stay (front panel) supported on the rear surface of the rear panel of the upper pallet from slidingly contacting a pair of right and left columns on the rear side of the lower pallet during nesting.

Further, according to the structure of the fourth aspect, when the nested pallet is lifted from the uppermost pallet and used, the pallet is protrudingly provided on the rear surface of a pair of left and right columns on the rear side of the upper pallet to be lifted. Since the upper end of the vertical plate can be guided forward by the guide projection before colliding with the dish-shaped cup at the upper end of the pair of right and left columns on the rear side of the lower pallet, the work of distributing the nesting is facilitated.

According to the fifth aspect of the present invention, at the time of nesting, the operation of fitting the pair of right and left columns on the rear side of the upper pallet into the front upper and lower frames on the left and right sides of the lower pallet is easy and reliable. In addition to the above, it is easy to position the upper pallet in the front-rear direction at the time of nesting only by setting the length in the front-rear direction of the guide protrusion protruding from the upper frame as described in the above embodiment. Can be done.

Further, according to the structure of the sixth aspect, the height of the pillars at the four corners of the bottom plate can be adjusted according to the height of the load to be handled, and can be used more conveniently.
