The lower frame 10 has a straight portion along the left and right sides of the pallet, and has a front engaging portion 22 which can be engaged with the front portion when approaching the pallet P from the front. And left and right side frames 11 and 12 provided at the left and right sides. The straight portion has substantially the same size as the front-rear length of the pallet, and has, for example, an L-shaped cross-sectional shape adapted to the upper corner of the side. The rear frame 13 has a straight portion along the rear side of the pallet P, and is integrated with the left and right frames 11 and 12 at both ends to form the lower frame 10.

Therefore, the lower frame 10 has a substantially U-shape surrounding the left side, the rear side and the right side of the pallet P, and only the front side of the pallet P is open over almost the entire width.

As an engagement means between the stacking frame A and the pallet P, a front engaging portion 22 is provided at the front of the left and right frames 11 and 12, and a rear engaging portion 25 is provided at the rear frame 13.

The front engaging portion 22 engages with the front of the pallet P from the front. The front engaging portion 22 includes, for example, an engaging piece 23 that enters the fork insertion opening of the pallet P from the front and an outer piece 24 that contacts the outside of the front corner of the pallet P. He cannot move left and right, but can move only forward. 3, 8, and 9
reference.

The rear engaging portion 25 engages with the rear portion of the pallet P to prevent the lower frame 10 from moving forward and to prevent the lower frame 10 from being accidentally pulled out. Such a rear engaging portion 25
Are engaged with the trailing edge of the pallet P, for example, from above so as to be able to restrain forward movement with respect to the pallet P, and can be engaged with the lower side of the pallet P, and can be engaged by an external operation. And a movable engagement piece 27 capable of releasing the engagement.

If the hook 26 can be made of angle iron, then the upper side of the frame 13 can be used. The movable engagement piece 27 only has to be able to move to the position of engagement with the pallet P and the position of disengagement therefrom. Such a movable engaging piece 27 is, for example, an elastic piece made of spring steel or the like provided with an engaging surface 28 capable of engaging a part of the lower surface of the pallet. 13 or legs. See FIGS. 6, 7 (a) and 7 (b).

In the illustrated example, the engagement surface 28 of the movable engagement piece 27
Is urged toward the pallet P in the direction of engagement, and a cutout is formed in the movable end 29 of the pallet P for engaging the bolt-shaped device 31 for detachment. It is formed on the bodies 16 and 17, and the nut 33 is screwed into the bolt screw portion to pull the bolt head hung on the movable end 29. However, this is merely an example, and a detachable pin may be provided to be engageable with the lower surface of the pallet engaging portion, and may be changed.

On the lower frame 10, front pillars 14, 15 having a fixed height are erected at intervals larger than the front width of the pallet P. For example, the left and right front pillars 14 and 15 are erected on a mounting portion 34 provided to protrude outside the front ends of the left and right frames 11 and 12 of the lower frame 10. See FIG. 3 and FIG. Also, the rear pillars 16 and 17 having a smaller interval than the front width of the pallet P are erected on the rear frame 13.

These pillars 14, 15, 16 and 17 are the minimum necessary according to technical common sense, but can be increased or decreased as needed. Further, the pillars 14 to 17 are preferably pipes better than angle irons, and have a height required to form a space S for placing a load therebetween.

Left and right front frames 14, 15 and rear column 1
6 and 17 are connected by a pair of left and right connection frames 18 and 19 which are connected to the front and rear at the respective upper portions. As described above, it is possible to form the U-shaped upper frame 20 by connecting the left and right rear columns 16 and 17 only. Contact frame 1 in the example shown
8, 19 are small members 35, 3 in the front width direction at front ends of portions extending forward in parallel at a wider interval than the rear pillars 16, 17.
5 are connected to the upper ends of the wider front pillars 14 and 15. However, the connecting frames 18 and 19 can also connect the front and rear pillars 14 to 17 diagonally.

Further, at the time of stacking, the other of the engagement means is engaged with one of the engagement means provided at the lower frame 10 or the lower part of each column to prevent the displacement to the left and right and back and forth. , 19 or above each column.

In the case of the illustrated example, one engaging means is a chevron-shaped concave portion 36 provided at the lower end of the front pillars 14 and 15, which is directed in either of the left and right directions. The other engaging means that can be engaged with this is a mountain-shaped convex portion 37 provided at the upper end of the front pillars 14 and 15, which are arranged at the same position on the left and right so as to engage when stacked. The other of the engaging means is a trailing edge 38 of the pallet P (see FIG. 9).
9, 39 are the rear ends of the connection frames 18, 19 or the upper rear frame 21.
It is provided on the left and right of.

The stacking frame A having such a configuration is
As shown in FIG. 8, the front engagement portion 22 is engaged with the front portion of the pallet P from above and from the front of the pallet P, and is engaged with the rear portion of the rear engagement portion 25. This is the state shown in FIG. In order to separate the stacking frame A from the pallet P, the above procedure is reversed, and the stacking frame A and the pallet P are disengaged from the movable engaging piece 27 of the rear engaging portion 25 by using a bolt-shaped tool 31, the rear portion is raised, and then pushed forward. good.

The stacking frame A integrated with the pallet P is stacked such that the distance between the front pillars 14 and 15 is wider than the front width of the pallet P, so that the upper pallet P almost contacts the lower pallet P. be able to. FIG. 10 shows the stacking state. The stacking frames A with the upper and lower pallets overlap while being shifted back and forth by the dimensions of the pillars 14 to 17, so that it is not necessary to remove the pallets when not in use, and also take up space. Can be cleared up

Further, since the upper and lower engaging means 36 to 39 are provided, the stacking frame A with pallets can be stacked vertically even with a load placed in the space S. Since the left-right and front-back movements are restrained, it is stable and safe above all. This is shown in FIG.
