Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for placing and supporting heavy objects.

[0002]

2. Description of the Related Art Conventional pallets have been made with considerable strength so as not to be easily crushed by a heavy object to be placed.

When unloading a heavy object placed on such a pallet from the pallet, the heavy object is once pushed or lifted and a pallet or a buffer interposed between the pallet and the heavy object. It was usual to remove the material after removing it, or move it while hoisting and remove it to a desired place.

As described above, in the past, when unloading heavy objects from a pallet, not only a considerable amount of labor was required for unpacking, but also jacks and hoists for lifting and unloading heavy objects were unloaded. It requires various equipment such as chain hoists. Therefore, the pallet invented for the purpose of labor saving of the unloading work from the pallet does not require such an unloading device at all, as disclosed in JP-A-1-99950. There is. As shown in FIG. 10, the pallet of the disclosed invention has the side edge 3 of the sheet material 2 and the tongue 3 after removing the locking members (not shown) of each part of the pallet when unloading the heavy object 1. When the portion 4 and the heavy load plate 5 are pulled out from the lower surface of the heavy load plate 5 and expanded, and then the heavy load plate 5 on which the heavy load 1 is placed is pressed in the direction of the arrow, the rising portion 6a of the flap 6 is pushed down and its height is increased. Since the weight is reduced, the bottom of the heavy object and the heavy object mounting plate 5
Create a gap between the upper surface and
Can be pushed out from the pallet, moved, and unloaded.

However, since this pallet has a complicated structure as described above, simplification thereof is strongly required, and when the heavy load plate 5 is pressed to unload a heavy load, the pallet and the sheet material 2 are removed. The bent portion formed by the rising portion 6a of the flap 6 and the bent portion formed by the rising portion 6a and the flat surface portion 6b are formed with acute-angled bent portions 7 and 8, and as a result, the repulsive force generated in the bent portion causes a heavy load. Various problems have been recognized, such as the mounting plate 5 not descending sufficiently, or once descending and then rising again due to the repulsive force so as not to interfere with the unloading of heavy objects.

[0006]

DISCLOSURE OF THE INVENTION The present invention has a simple structure and is suitable for placing heavy objects, and does not require any equipment for unloading heavy objects, and is simple without any hindrance. The purpose is to obtain a pallet that can be easily unloaded.

[0007]

[Means for Solving the Problems] A plurality of flaps each having a Z-shaped cross-section and having a vertical rising portion are juxtaposed in parallel with each other between a bottom plate and a heavy load plate, and the left and right edges of the bottom plate are provided on both side edges. ,
An edge member having a U-shaped cross-section and having the same height as the rising portion of the flap is provided with its opening inside, and the upper surface of the edge member is contact-inserted into the back surface side of the weight placement plate.

[0008]

Since the pallet of the present invention has the above-mentioned structure, the pallet is constructed by pressing the heavy load plate of the pallet on which the heavy load is placed after removing the locking member of the pallet. Since the rising part of the flap is pushed down and its height is reduced, a gap is created between the bottom of the heavy load and the upper surface of the heavy load plate, and it is possible to push out the heavy load from the pallet using casters to move and unload it. Since the bent portion of the flap is not formed with an acute-angled bent portion, the heavy load plate is easily and sufficiently lowered.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a bottom plate, 2 is a heavy load plate, and between the bottom plate 1 and the heavy load plate 2, there is a rising part 3a which rises vertically and the upper and lower parts of the rising part 3a. A plurality of flaps 3 each having a Z-shaped cross section and provided with flat portions 3b and 3c connected to both ends are juxtaposed in parallel with each other, the flat portion 3b is placed on the bottom plate 1, the flat portion 3c is placed on the heavy object placement plate 2, and an adhesive or the like is used. It is firmly fixed through. Further, on both left and right edges of the bottom plate 1, edge members 4 having a U-shaped cross section by bending are made to have their openings inside, and contact portions 4a with the bottom plate 1 are firmly fixed through an adhesive or the like, The contact portion 4b with the object placing plate 2 is simply fitted and inserted into the lower surface of the heavy object placing plate 2. Therefore, it goes without saying that the rising portion 4c of the edge member 4 has the same height as the rising portion 3a of the flap 3.

Between the left and right flaps 3 and the edge member 4, a doglegged base plate 5 shown in FIG. 2 is formed by bending one end edge 5a of the rising portion 3a of the flap 3 and the flat portion 3b. The other end edge 5b is abutted on the bent line portion 7 formed by the rising portion 4c of the edge member 4 and the contact portion 4a of the bottom plate 1, and the ridge line portion 5c is placed on the heavy load. The edge member 4 is in contact with the back surface of the placing plate 2 and is also in contact with the tip edge portion of the contact portion 4b in contact with the heavy object placing plate 2. The base plate 5 is used for reinforcement and is not necessarily used if there is no risk of the pallet being crushed by a heavy object placed on the pallet.
Further, although the rightmost flap 3 and the edge member 4 in FIG. 1 have been described as being separate, they may be integrated as a series and the flap 3 and the edge member 4 may be formed by bending. Of course.

In the pallet of the present invention, the contact portion 4b of the edge member 4 of the formed body M formed as described above is fitted and inserted into the lower surface of the heavy load plate 2 as shown in FIG. 2 and the rising portion 4c of the edge member 4 are locked by a gum tape or other suitable locking member 8.

Then, on the pallet of the present invention thus obtained, as shown in FIG. 4, the heavy object 9 directly contacts the heavy object mounting plate 2 at the bottom surface of the heavy object, or as appropriate. Contact mounting is performed via the cushioning material 10.

Therefore, now, as shown in FIG.
And the flap 4 is pulled out from the lower surface of the heavy load plate 2 when the edge member 4 comes into contact with the heavy load plate 2 and the base plate 5 is used. When pushing the rising portion 3a of the flap 3 so as to fall about the bending line portion (from right to left in FIG. 6), the rising portion 3a of the flap 3 is easily pushed down,
The height of the heavy object placement plate 2 fixed to the flat surface portion 3c of the flap 3 is reduced.

That is, as shown in FIGS. 4 to 7, a heavy object 9 having casters 11 is placed on the pallet of the present invention via a cushioning material 10 as appropriate, and the casters 11 are separated from the bottom surface of the pallet. In the state, when the package is unpacked and the heavy load plate 2 on the pallet is pressed, the rising portion 3a of the flap 3 is easily pushed down as shown in FIG. 7 through the states of FIGS. Since the height is reduced, the casters 11 of the heavy object 9 come into contact with the bottom surface of the pallet, and the heavy object mounting plate 2 and the cushioning material 10 are separated from the bottom surface of the heavy object 2. Therefore, if the heavy object is pushed out, it is easy to move from the pallet. You can move to and unload. Then, as a result of all the bent portions of the flap 3 and the edge member 4 being pushed down in an acute angle shape, repulsive force is not generated in the bent portions and the heavy load plate 2 does not rise again.

In the case of a heavy load without casters, use a pallet in which the plate surface of the heavy load plate 2 is smaller than the bottom surface of the heavy load 9, and the both edges of the flap 3 are parallel to the pushing direction of the flap 3. A pedestal with casters is prepared along with, and when the pallet flap 3 is pushed down, the bottom of the heavy load 9 extending from the heavy load mounting plate 2 is unpacked in the same manner as described above. All you have to do is receive the cradle. Needless to say, when placing a heavy object smaller than the pallet of the present invention, the heavy object is placed and used on the heavy object placing plate regardless of the presence or absence of casters.

In the first embodiment, it has been described that the bottom plate 1 and the edge member 4 are provided separately, but in the second embodiment shown in FIG. 8, both left and right edge portions of the bottom plate 1 are described. Is extended and extended, and the extended portion 12 is bent to form a side edge portion. The step of adhesively fixing the contact portion 4a of the edge member 4 on the bottom plate 1 as in the case of the first embodiment Can be omitted.

Further, in the third embodiment shown in FIG. 9, an extension portion 13 having a width equal to the rising portion 3a of the flap 3 is provided on the bottom plate 1 shown in the second embodiment. The plate members are laid in a cross shape and adhered and fixed, and this is used as a bottom plate, and when forming a pallet, the front end edges 13a of the extending portions 13 located at the front and rear are placed on the lower surfaces of the end edge portions 2a and 2b of the heavy load plate 2. The pallets are brought into contact with each other, whereby the strength of the pallets can be further increased and crushing of the pallets at the time of placing a heavy load can be avoided.

In the above description, on the bottom plate 1 shown in the second embodiment, a plate member having an extending portion 13 having a width equal to that of the rising portion 3a of the flap 3 is superposed in a cross shape. Although it is described that they are adhered and fixed together and used as a bottom plate, it goes without saying that it is also possible to make a single cross-shaped plate material having the extending portions 13 and 12 in the front, rear, left and right, and use this as a bottom plate. Is.

As the bottom plate 1, the heavy load plate 2, the flap 3, the edge member 4 and the base plate 5 used in the present invention,
A single-sided cardboard with a liner base paper attached to one side of a corrugated core base paper, a double-sided corrugated board with liner base paper attached to both sides of a corrugated corrugated base paper, and a double-sided corrugated board with a single-sided corrugated board Double-sided corrugated board, double-sided corrugated board, and three-layer corrugated board in which single-sided corrugated board is further adhered are appropriately selected and used in relation to heavy items, and there are three types of corrugated board: A flute, B flute, and C flute. However, they can be used alone or in combination. Further, as long as it is a material that can withstand the weight of a heavy object and can bend and stretch
An appropriate plate material such as a plastic plate or a metal plate can be used.

[0021]

As described in detail above, in the pallet of the present invention, a plurality of flaps each having a Z-shaped cross section and having a vertical rising portion are juxtaposed in parallel with each other between the bottom plate and the heavy load plate. On the left and right edges of the bottom plate, edge members having a U-shaped cross-section and having the same height as the rising portions of the flaps are provided with their openings inside, and the upper surface of the edge member is the back side of the heavy load carrying plate. Since it comes into contact with and is inserted into a pallet, when unloading a heavy object on a pallet from the pallet, the heavy object can be pushed up with a jack or the like, or suspended with a chain hoist, etc. Instead of pressing the pallet, the heavy load plate is pushed to push down the rising parts of the flaps that make up the pallet, and the height of the pallet is reduced, making it possible to easily unload heavy loads from the pallet. What As a result, all the bent parts of the flap and the edge member are pushed down in an acute angle, and as a result, repulsive force is generated at the bent parts and the heavy load plate does not rise again and hinders unloading. Workers can easily perform unloading work without much effort,
It was confirmed that not only contributed greatly to labor saving, but also the assembling and unpacking of the pallet was easy and the workability was greatly improved.
