BACKGROUND OF THE INVENTION This invention relates to a forklift
The present invention relates to a pallet comprising a honeycomb made of cardboard for receiving luggage .

[0002]

2. Description of the Related Art Cardboard pallets are lightweight, easy to handle, suitable for disposal by incineration, and inexpensive. Various configurations have been devised from the viewpoint of lightness, simplicity of assembly, cost, and the like.

A conventional cardboard pallet generally has a pallet body formed by bending a cardboard into a rib shape in order to obtain load resistance. Further, in order to increase the load resistance, a number of paper tubes may be provided inside (Japanese Utility Model Publication No. 46-29700).

[0004]

Conventional pallets made of corrugated cardboard have complicated structures, and especially when importance is placed on load-bearing capacity, weight reduction and cost are sacrificed by frequent use of members. Was supposed to be In addition, the structure is difficult to assemble by the user, and the assembly is often performed at the factory, knowing that it is disadvantageous for transportation to the user.

[0005] Regarding the load resistance, it is desirable to adopt a structure in which the load is evenly received. However, when the corrugated cardboard is bent to form a rib structure, there is a space that runs back and forth or left and right. In addition, the rib structure does not bend in one direction, for example, in the front-rear direction, but easily bends in the other direction perpendicular to the rib structure. there were.

[0006] In the case of using a paper tube, an extremely high load-bearing property can be obtained at the portion of the paper tube, but there is a weak point that a drop easily occurs at other portions. Also, the paper tube can never be folded down for transportation, and the weight of the paper tube will make it lighter.

The present invention has been made in view of the above-described circumstances,
An object of the present invention is to provide a pallet made of a honeycomb made of corrugated cardboard, which is suitable for assembly by a user and provides uniformity in load resistance without using many members.

[0008]

In order to achieve the above object, a first aspect of the present invention provides a pallet body having forklift claws insertion holes at both left and right ends so that the direction of expansion and contraction of a honeycomb structure becomes forward and backward. And a pallet made of a honeycomb made of corrugated cardboard, comprising a combination of a honeycomb structure as described above and a pair of left and right rectangular cylinders respectively fitted into both insertion holes.

A second invention is a cardboard box structure as a pallet body provided with forklift pawl insertion holes at both left and right ends, a pair of left and right rectangular cylinders fitted respectively into both insertion holes, a cardboard box structure A pallet made of a corrugated honeycomb made of a combination with a reinforcing honeycomb structure having a compressive strength to be filled in the body.

[0010]

The honeycomb structure can be expanded and contracted in one direction, so that it can be folded by contracting, and the rectangular cylinder can be folded flat so as to have a rhombic cross section. In the case where the cardboard box structure is provided as in the second invention, the cardboard box structure can be transported in an unfolded state, and in any case, transportation to the user is advantageous.

The assembling is not a complicated bending structure, and is extremely easy to assemble. In addition, in the assembled state, the honeycomb structure can support the load evenly, so that very strong load resistance can be obtained.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of the first invention. A pallet made of a corrugated cardboard honeycomb has a honeycomb structure 1 as a pallet body and a rectangular corner into which a forklift claw is inserted. It consists of a combination with the cylindrical bodies 3 and 3. Each of them is made of corrugated cardboard, and as the corrugated cardboard, double-sided corrugated cardboard, double-sided corrugated cardboard, or the like having strength is used. In addition, it is desirable to be reinforced by impregnating with a synthetic resin or pasting a plastic film on the surface.

The honeycomb structure 1 has a hexagonal honeycomb structure formed by partially adhering a long corrugated cardboard in a strip shape to form a hexagonal honeycomb structure. Insertion holes 5, 5 for inserting 3, 3 are formed. Therefore, the longitudinal direction of the rectangular cylinders 3 and 3 is the expansion and contraction direction, and the locking pieces 7 and 7 are provided at both ends of the rectangular cylinder 3 so as to be engaged with the holes of the honeycomb so as not to contract. In addition, as the honeycomb structure, in addition to the hexagon, a honeycomb structure such as a square, a sine waveform, and a shifted hexagon can be suitably used.

The rectangular cylinders 3, 3 are held in a rectangular cylinder assembly by wire stapling, and a pair of left and right locking pieces 7, 7 are formed on one surface of one end of the rectangular cylinder 3, As a forming means, a part of the corrugated cardboard as a raw material is pulled out and raised to stand up as an extension of the side wall. 6 is the hole. The hook pieces 7 are desirably provided on both the upper and lower surfaces of the rectangular cylindrical body 3. However, even if only one surface is provided, the honeycomb structure 1 can be held.

In order to obtain compressive strength, the corrugated cardboard is used in the honeycomb structure 1 and the rectangular cylinders 3 and 3 so that the wave of the core is up and down, that is, the wave traveling direction is horizontal. Assembled. In the honeycomb structure, not only can it receive loads evenly, but also it has bending resistance and compression resistance while being lightweight,
Maintains strength not to bend in the front-rear direction and the left-right direction. In order to supplement these strengths, the face plate 8 is attached to the upper and lower surfaces or either one of them, and the paper tube 9 is placed in some honeycomb holes.

FIGS. 3 to 5 show different embodiments of the second invention. In each case, a corrugated cardboard box structure 2 is used as a main body, square tubes 3 and 3 are combined therewith, and a reinforcing honeycomb structure 4 is used. It is decorated. This reinforcing honeycomb structure 4 is formed from a so-called corrugated cardboard structure, regardless of the material, such as paper corrugated cardboard such as single-sided corrugated cardboard, double-sided corrugated cardboard, double-sided corrugated cardboard, or double-sided corrugated cardboard. And it is not particularly limited.

A pallet made of a cardboard honeycomb shown in FIG. 3 uses the structure of a C-1 type cardboard box for the cardboard box structure 2. That is, the cardboard box structure 2 is composed of the body 2a and the lid 2b.
a and the lid 2b are formed with insertion holes 5 and 5 for inserting the rectangular cylinders 3 and 3, respectively. The lid 2b is fixed to the upper surface of the rectangular cylindrical body 3 and the body 2a is fixed to the lower surface by bonding. Alternatively, it may be stopped with a wire needle.

The reinforcing honeycomb structure 4 is filled in the body 2a without any gap, and is partially stopped by the body 2a or the rectangular cylindrical body 3 so as not to shrink. Also, in the reinforcing honeycomb structure 4, the paper tubes 9, 9,... Are fitted in the honeycomb holes by almost even distribution to increase the compressive strength. The assembling of the paper tube 9 is a work of simply dropping it into the hole, and there is no need to stop it, and the workability is good. Further, since strong load resistance can be obtained only by the honeycomb structure, it is not necessary to use the paper tube 9 at all.

The pallet made of a corrugated cardboard honeycomb shown in FIG. 4 uses the structure of an A-1 type cardboard box for the cardboard box structure 2 and has a pair of inner flaps 11 and 11 and a pair of upper and lower inner flaps. Outside flap 13, 1
And insertion holes 5 and 5 for inserting the rectangular cylinders 3 and 3 in the body. Further, the inside is filled with a reinforcing honeycomb structure 4 without any gap, and a paper tube 9 is fitted therein. For holding the assembled form, the inner flap 11
Is fixed to the rectangular cylindrical body 3 with an adhesive or a wire needle, and both outer flaps 13 and 13 are stopped with a wire needle or an adhesive tape.

A pallet made of a cardboard honeycomb shown in FIG. 5 is a case where the cardboard box structure 2 is of the B-2 type. Are cut off at the points (1) and (2) so as not to open and are fastened to the front or rear face walls (21, 21) by insertions (19). Further, the face wall 2 is formed by the insertion holes 5 and 5 of the rectangular cylinders 3 and 3.
Since the strength is lost at the point where 1, 21 are cut off, the insertion holes 5, 5 are formed as window holes to avoid the loss. For this reason, the supplementary plates 23, 23 are laminated and stopped on both the upper and lower surfaces of the rectangular cylindrical body 3, because the thickness of the rectangular cylindrical bodies 3, 3 is smaller than the dimension between the canopy 15 and the ground lid 17. In addition,
If the complementary plate 23 is formed wide so as to cover the entire surface, the bending strength in the lateral direction increases.

[0022]

As described above, according to the present invention, there are the following excellent effects.

Before assembling a pallet made of a corrugated cardboard honeycomb, at least most of the members can be folded small, which is advantageous for transportation. In use, the honeycomb structure does not require complicated folding. Since it has a very simple structure that ensures strength and is easy to assemble, it is exactly suitable for use by users.

In the assembled state, since the load can be evenly supported by the honeycomb structure, a very strong load resistance can be obtained without using many members, and it is suitable for reducing the weight of the pallet . In addition to the simple structure, inexpensive provision is also possible.
