Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage rack, and more particularly to a storage rack capable of preventing a stored product from falling due to an earthquake or the like in a warehouse or a factory.

[0002]

2. Description of the Related Art A form of storing stored items in a shelf is a method of placing the stored items directly on a flat shelf board, or placing stored items with a pallet on a shelf in which columns and beams are assembled in a grid pattern. There is a way to do it. The former is suitable for a relatively small storage item, and the latter is suitable for a large heavy item stored by using a forklift. In this latter method, since the contact area between the shelves and the stored items is small, there was a risk that the stored items would fall together with the pallet if there was a large vibration due to an earthquake or the like. In particular, there is a problem of this kind with stored goods that are extremely dangerous when dropped, such as explosives and chemicals. Therefore, although measures such as attaching a stopper with an L-shaped cross section to the rear side of the storage shelf have been taken conventionally,
Since the stopper is attached outside the back of the shelf, there is a drawback that it interferes with the equipment on the back side of the shelf, and no measures have been taken to prevent the stored items from falling toward the front.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and to provide a storage shelf in which stored items do not easily drop from the shelf due to an earthquake or the like. .

[0004]

[Means for Solving the Problems] Horizontal beams 3, 3, between pillars 7, 7 ...
... and the vertical beams 2, 2, ...
2. In a storage shelf in which the double-sided pallet 4 is placed on the horizontal beams 3 and 3, the lower plate 4b of the pallet 4 is provided on the upper surfaces of the vertical beams 2 and 2.
It is characterized in that an engaging claw 1 for engaging with is provided in a protruding manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a storage shelf according to the present invention will be described below with reference to the drawings. The storage shelves, like the conventionally known shelves, are columns 7 standing up and down with a space left, right, front and back so that the space of one shelf can accommodate two pallets.
7, ... Between horizontal beams 3, 3, ..., Vertical beams 2, 2, ...
・ The structure is formed by connecting a plurality of shelves to form a shelf, and for these members, steel materials such as H-shaped steel and grooved steel are used. The distance between the columns 7, 7 in the front-rear direction is slightly shorter than the length of the pallet, and the cross beam 3 connected between the columns 7, 7 on the left and right.
Is slightly longer than the width of two pallets, and a plurality of (four in the illustrated embodiment) vertical beams 2, 2 are connected between the front and rear horizontal beams 3, 3.

Thus, the stored items are stored in the pallet 4 shown in FIG. 6 on the storage shelves and are stored together with the pallet. The pallet has three columns 4c sandwiched between them as in a known double-sided pallet. The upper plate 4a and the lower plate 4b are stretched from both upper and lower sides like a cage. The structure shown in FIG. 3 is a locking claw 1 and a lower plate 4b which are projected on the upper surface of a vertical beam 2 described later.
In order to engage with the side wall of the lower plate, the gap e between the lower plates in the middle of the lower plate 4b is made larger than the other gaps f.
All the gaps between b may be of size e. Depending on the case, an engaging hole for engaging with the locking claw 1 may be provided in the lower surface of the lower plate 4b, or a through hole may be provided in the lower plate.

As shown in FIG. 1, a lower plate 4b of the pallet 4 is placed on the upper surface of the vertical beam 2 when the pallet is placed on a shelf.
A locking claw 1 made of steel for locking the is projected by welding or the like. The thickness of the locking claw 1 is smaller than the gap distance e of the lower plate 4b of the pallet 4, the height thereof is lower than the thickness of the lower plate 4b, and the width thereof is substantially equal to the width of the vertical beam 2. Further, the cross-sectional shape is preferably trapezoidal or tooth-shaped. Although the position of the locking claw 1 is installed in the vicinity of the center of the vertical beam 2 in FIG. 3, the position is not limited to the center and may be any position as long as it can be engaged with the lower plate 4b. Although FIG. 4 shows a use state in which two pallets are placed on one shelf, when the stored item 6 is long and extends beyond the pallet 4, as shown in FIG. One pallet may be placed on the beams 2 and 2. In this case as well, the pallet has locking claws 1, which are projected on the vertical beams 2, 2.
It is engaged at one and two points.

The pallet 4 has left and right cavities when viewed from the front, with the claw insertion side of the forklift 5 as the front, into which the left and right claws of the forklift 5 are inserted.
The forklift 5 is of a laterally moving type, and the reach-in and reach-out directions of the claws are orthogonal to the traveling direction.
The storage item 6 placed on the upper plate 4a is fixed to the pallet 4 by a lashing band 8 to prevent the storage item 6 from falling off the pallet.

[0009]

The two pawls of the forklift 5 are inserted into the cavities of the pallet 4 at the bottom of the storage item 6 and lifted up to move the storage item 6 fixed to the pallet 4 with the lashing band 8 to move the storage rack. The claws of the forklift 5 are extended at a predetermined position, and the pallet 4 integrated with the stored item 6 is placed on the vertical beam 2 and the horizontal beam 3. Then, since the locking claw 1 projecting from the vertical beam 2 is located in the gap between the lower plates 4b of the pallets 4, the pallet 4 shifts in the front-rear direction even if the shelves swing due to an earthquake or the like. Since the lower plate 4b is engaged with the locking claw 1, the movement in the front-rear direction is restricted, and the pallet 4 does not fall off the lateral beam 3. The movement of the pallet 4 in the left-right direction is restricted by the column 7 and the adjacent stored item 6. When the stored item 6 is taken out, the claws of the forklift 5 are inserted into the pallet 4 and lifted up, and the reach-in is performed to take the stored item 6 into the forklift 5, and the forklift 5 is moved and carried out.

[0010]

According to the present invention, even if the shelf swings in the front-back direction due to an earthquake or the like, the lower plate of the pallet is engaged with the locking claw that is projected on the vertical beam, and the movement of the pallet is suppressed. So the stored items will not fall off the shelves or easily. In addition, even if there are already stored items on the storage shelf, trying to store them in duplicate,
Even if the forklift 5 deviates from the track or the like and presses a stored item that is already stored, the stored item does not drop easily.

Further, by making the cross section of the locking claw 1 trapezoidal or tooth-shaped, there is a taper even if the clearance between the locking claw 1 and the lower plate 4b does not match due to some accuracy error during mounting. It becomes easy to fit into the gap of the lower plate 4b.
