Description

[Detailed description of the invention] [Industrial application field] The present invention relates to pallets that can be placed in multiple stages in a container, which can be loaded and unloaded using a forklift and is convenient for stacking and storage when not in use. It is something.

[Conventional technology]

Containers are convenient for storing cargo, storing it on transport aircraft, and loading and unloading cargo, but loading operations into the enclosed container itself are limited. Since the work must be done from the opening door, it is inefficient.

Therefore, with the intention of improving the efficiency of loading work into such containers, by placing rollers on the bottom plate of the container, the bottom plate that is pulled out of the container is loaded by outside loading work, and the bottom plate and the bottom plate are loaded into the container all at once. The housing device was proposed (for example,
-Refer to Publication No. 44591).

[Problems that the invention aims to solve] By the way, when considering the situation of container transportation,
When using transportation means such as vehicles, consideration must be given to the impact on the container itself during loading and unloading onto the transport vehicle or during transportation.

However, not only is the container itself quite strong, but as seen in the conventional means mentioned above,
When additional equipment is installed, it is important to ensure the impact resistance of the equipment and its condition within the container. Moreover, it is economically undesirable that the weight of the container is extremely increased by this type of additional equipment.

On the other hand, there are some items that cannot be stacked and accommodated, and conventional means have poor efficiency in accommodating such items in containers, and there is a strong desire for improvement.

Furthermore, in order to efficiently carry out work such as storing or transporting cargo into a container, especially reloading, forklift work using pallets is preferable.

Therefore, in view of the above-mentioned circumstances, the object of the present invention is to improve a pallet that can improve the efficiency of loading and unloading into containers and the storage efficiency in this type of container transportation.

[Means for solving problems]

For this purpose, in the present invention, first, the floor frame of the pallet is assembled vertically and horizontally with square tubes having hollow parts that will serve as fork pockets, and aggregates having notches that fit into the square tubes. Attach and configure. A load collapse prevention member is foldably attached around the four sides of the pallet, and the load collapse prevention member is entirely formed into a truss-shaped body with many gaps.

Further, corner metal fittings are provided at the four corners of the pallet and protrude from the pallet floor surface by an amount corresponding to the thickness when the load collapse prevention member is folded onto the pallet floor surface, and an outer frame parallel to the square tube material of the floor frame is provided. The frame is formed with a portion that engages with a support bracket placed on the side of the container.

[Effect]

The rectangular tube material constructed to obtain fork pockets is not only a fork receptacle, but also a rectangular column, so it can also be used as a spanning aggregate for the pallet floor frame. to maintain pallet strength, and
Effectively reduces pallet weight.

By configuring the cargo collapse prevention member, which originally acts to prevent cargo stacked on a pallet from collapsing, into a truss-like structure, many gaps within the frame can be used to hang ropes for packing. Functions as a stop part. Further, the collapse prevention member, which is foldable on the pallet surface, can be folded when the pallet is not in use, thereby making it possible to stack the pallets in multiple layers in a small volume.

When the pallets are stacked and stored in multiple layers, the corner metal fittings protruding from the four corners of each pallet act as a spacer between the stacked pallets and as a lateral slip prevention material.

The engagement portions with the brackets provided on the pair of opposing bone frames within the four-periphery frame of the pallet are the brackets selectively arranged on the fitting attachment portions provided at different height positions on the side walls of the container or the supports of the walls, etc. Ensure that the pallets are secured when placed on the pallet. Furthermore, depending on how the brackets are arranged in the container, several pallets can be arranged in multiple stages.

Moreover, these pallets can be carried into the container, installed, and taken out by a forklift using the fork pockets.

〔Example〕

Next, the illustrated embodiment of the present invention will be described.

As shown in FIG. 1, according to one embodiment of the present invention, a four-cornered pallet body 1 with a certain floor thickness has fork pockets 2 on one opposite side (hereinafter referred to as the horizontal frame). 2, and hinges 4 are provided on each of the four peripheral sides of the main body 1 to prevent the load from collapsing.
It is foldably attached as shown by the chain line in the figure. The right angle backing plates 7 provided at the four corners of the pallet main body 1, which are formed by orthogonally abutting the horizontal frame 5 and the other vertical frame 6 on the opposite side, have a rectangular space formed by the plates 7. Corner fittings 8 are integrally attached.

FIG. 2 is a partially cutaway perspective view of an example of a container to which the pallet of the present invention is applied. , 11 are provided with engagement grooves 1 at arbitrary height positions.
3, 13... are arranged in series, and the engagement grooves 13, 13
The pallet main body 1 can be placed on the pallet body 1 by supporting the brackets 14, 14, which are engaged with the pallet. This container 9 has the side plate portions 11 and 11 in order to enable storage in a small volume when not in use.
The configuration previously proposed by the applicant of the present invention (Utility Application No. 1983-201263), such as making it possible to fold in two, is adopted.

By the way, as shown in the third figure, the fork pocket 2 in the pallet main body 1 is made of a lid body 15 which has projecting edges 15a on both ends of a steel material having a U-shaped cross section.
and a flat plate 16 having a width that abuts the edge 15a are integrally welded together at the overhanging edge 15a. Then, as shown in Figure 5, this square tube material 17 is also used as the floor aggregate of the pallet body 1, and the portion that intersects with the square tube material 17 is formed into a notch 18 for fitting. bone 1
9 is combined vertically and horizontally to form a framework. At this time, the lower edge of the horizontal rib 19 is assembled in such a manner that it is in contact with the overhanging edge 15a of the square tube member 17.

Corresponding to this framework, the horizontal frame 5 attached to the end of the horizontal rib 19 is also attached to an ear piece 5a formed by folding up the lower edge of a steel material having a U-shaped cross section.
The lower surface of the pallet main body 1 is made flat by assembling it with the lower surface of the pallet body 1 in contact with the lower surface of the pallet body 1, and by placing the transverse rib 19 on top by the folded-up height of the ear piece 5a.

The cargo collapse prevention member 3 includes an outer peripheral frame 3a having an attachment portion by the hinge 4 and the frame 3a.
A reinforcing frame 3b bent into a mountain shape in the area surrounded by
The bent top part is welded to the inside of the frame 3a to form a truss-like body with many gaps. Therefore, when the pallet is used in an upright position around the pallet main body 1 as shown in the first figure, it is possible to prevent the loads stacked on the main body 1 from shifting laterally, and to insert packing ropes or It becomes possible to hang a hook or the like, and the gap can function as a locking part. In addition, in order for the cargo collapse prevention member 3 to perform its function as a locking portion, it is sufficient if it is a truss-like body with many gaps, so the shape of the reinforcing frame 3b is not limited to the chevron shape, but may be corrugated. A suitable shape can be used.

Furthermore, the tips of the corner metal fittings 8 arranged in the four corner spaces of the pallet body 1 protrude from the upper surface of the floor plate 20 (see Fig. 4) of the pallet body 1, and this protruding height is used to reduce the load collapse. The thickness is approximately the same as the thickness of the prevention member 3 when folded onto the surface. As a result, when the pallet main body 1 is stored when not in use, the pallets above and below the stack can be stacked in a small bulk state by folding the collapse prevention member 3 (see Fig. 4). Each corner fitting 8 in the main body 1 abuts each other,
It functions as a spacer between these, and
Since it is engaged with each pallet main body 1 at the four corner spaces, it also functions as a material to prevent the laminated pallets from shifting laterally.

According to the present invention, as shown in FIG.
A bracket 1 is inserted into the T-shaped engagement grooves 13, 13, which are opened in the vertical bars 11, 11 of the container 9 through the wide grooves, and is prevented from coming off by the narrow grooves.
A U-shaped metal fitting 22 having an engagement hole 21 into which the engagement protrusion 14b protruding from the horizontal arms 14a of 4, 14, . . . is fitted is integrally attached to the horizontal frame 5. Therefore, when the fork of the transport lift is inserted into the fork pocket 2 of the pallet main body 1, the pallet is lifted and moved, and placed on the brackets 14, 14, etc., which have been set at a horizontal height position in advance. By properly fitting the mating protrusion 14b and the engaging hole 21, it is possible to prevent the pallet body 1 from shifting later and to secure the pallet body stably. Moreover, depending on the installation state of the brackets 14, 1414...
It is now possible to place several stages of pallet bodies 1 in a container, and cargo that is unsuitable for stacking can be stacked in a row on each pallet body 1, allowing loading with high utilization of space inside the container. can.
Although the engaging hole 21 is constructed using the U-shaped metal fitting 22, the hole 21 may alternatively be formed directly in the horizontal frame 5.

[Effect of idea]

In this manner, according to the pallet of the present invention, by configuring the rectangular tube material having fork pockets to be used as a part of the floor frame, either the fork pocket component material or the frame material can be omitted. Therefore, the structure of the strong floor frame can be made relatively lightweight, and by attaching the load collapse prevention member formed in a truss shape so that it can be folded freely, the original load can be attached to the load collapse prevention member. In addition to preventing slippage, this can be used as a locking part, and by folding, the volume of the pallet can be reduced when not in use, making it convenient for stacking and storing a large number of pallets. By installing corner fittings with tips that protrude from the pallet floor, it maintains gaps between pallets and prevents them from shifting sideways during stacked storage, allowing safe and reliable stacking. By changing the height position inside the container and adjusting the placement and engagement with the brackets installed in advance, it is possible to arrange pallets in multiple stages inside the container, and it is also possible to prevent shaking shocks during transportation, etc. The pallet of the present invention is extremely useful in practice as a device of this type, as the pallet can be safely secured even in the case of a pallet.

It goes without saying that the pallet of the present invention is not limited to application to the container apparatus shown in the second figure, but can also be applied to existing containers in which brackets can be installed to support the pallet.
