Further, the right vertical member 6 and the vertical member 6 are two horizontal members 9 and 9 along the depth direction, and the left vertical member 7 and the vertical member 7 are two horizontal members along the depth direction. The members 9 and 9 are connected to each other.
Further, the front horizontal members 8 and 8 and the rear horizontal members 8 and 8 respectively dividing the first, second and third mounting shelf spaces 2, 4 and 5 receive articles. Four mounting frames 10 for mounting are connected to each other along the depth direction. The number of the placement frames 10 is appropriately set according to the size and weight of the article to be loaded. These members are fixed to each other by means such as welding.

    Reference numeral 11 denotes a pallet on which articles 12 are loaded, which is made of a material such as reinforced plastic. Reference numerals 13 and 13 denote two pawls of the forklift, that is, an insertion port into which the fork is inserted when the pallet 11 is conveyed together with the article 12 by the forklift. The pallet 11 is indicated by what is generally called a flat pallet. However, although not shown, of course, the pallet itself may be a box pallet formed in a box shape for storing articles.

    Reference numeral 14 denotes a pallet displacement prevention device. The shift prevention device 14 is provided on the horizontal member 8 of the stacking shelf main body 1. As shown in FIGS. 4 and 6, the slip prevention device 14 is formed in a substantially U shape with one side open, and is attached to the horizontal member 8 so as to hold the horizontal member 8 from the side surface 15 side. At the same time, an attachment member 17 having screw portions 16 and 16 formed at the end on the open side is provided.

This will be further described with reference to FIG. That is, the widths of the stopper members 24 and 24 are set so that the dimension S between the attached slip prevention devices 14 and 14 is smaller than the width dimension L of the pallet 11.

FIGS. 8 and 9 show the displacement state of the pallet 11, and the pallet 11 is usually placed at a fixed position indicated by a solid line. For example, when the pallet 11 adjacent to the placed pallet 11 is lowered for transfer from the placing shelf main body 1, the pallet 11 placed at a fixed position is affected by the impact and vibration caused by the forklift, and the arrow Move in the direction of.
However, the pallet 11 is held at the position indicated by the chain line because the shift is suppressed by the stopper member 24 of the shift prevention device 14. For this reason, it is possible to prevent the pallet 11 from falling from the stacking shelf body 1. Further, since the pallet 11 does not protrude forward from the horizontal member 8, the pallet 11 can be placed and stored in an organized state.

    Further, the width of the stopper member 24 formed between the pallet 11 and the pallet 11 is wider than that near the vertical members 6 and 7. However, if the two pawls of the forklift, that is, the fork does not interfere with the stopper member 24 when the pallet 11 is loaded and unloaded, if there is no problem, the wide stopper member 24 may be unified. .

Further, as shown in FIGS. 5 and 6, the shift prevention device 14 provided at a position between the pallet 11 and the pallet 11 is not originally provided one by one so as to face the pallets 11 and 11. However, as described above, by forming the stopper member 24 wide, it is possible to prevent the two pallets 11 and 11 from being shifted by the single shift prevention stand 14.
Thereby, simplification of a component can be achieved. The wide stopper member 24 is formed so as to protrude below and to face the bottom surface 27 of the horizontal member 8 while being fixed to the horizontal member 8 of the stacking shelf body 1 of the pallet 11. A guide portion 28 is provided. When the stopper member 24 is attached to the horizontal member 8, the guide portions 28 and 28 make the guide portion 28 a horizontal positioning guide so that the stopper member 24 is correctly attached to the horizontal member 8. This can surely prevent the deviation. The guide portions 28 are positioned on the left and right via the mounting holes 18 positioned below the stopper member 24.

    On the other hand, the height dimensions of the mounting shelf spaces 4 and 5 in the second and third stages are required to lift the bottom surface 23 of the pallet 11 above the upper end 21 of the stopper member 24 by a forklift when the pallet 11 is loaded and unloaded. Therefore, it is set in consideration of this dimension.
