Is folded inside, and in this folded state,
The loading platform portions 13a and 13b are stacked in a state in which the surfaces constituting the loading surface are brought into contact with each other and the remaining side portions other than the one side portion to be connected are aligned. Further, the connecting portion 14 is arranged at the center in the longitudinal direction of the cargo bed 11 in the stretched state so as to extend over the entire width in the width direction. The longitudinal direction and the width direction are perpendicular to each other and the thickness direction.

The support legs 12a to 12d have the same structure as each other, and are located on the side opposite to the side on which the loading surface 15 of the loading platform 11 is formed, specifically, from the loading platform 11 to the loading surface. The protrusions 15 are provided on the opposite side to and are provided at intervals in the longitudinal direction of the loading platform 11. The intervals between the support legs 12a to 12d may be equal intervals or different intervals, but are equal intervals in the present embodiment.

Has been done.

According to the pallet 10 of the present embodiment as described above, the loading platform 11 is configured to be foldable and extendable as described above, and when the luggage 18 is loaded and transported, the loading platform 1 is used.
When the vehicle 1 is extended and the luggage 18 is not mounted on the luggage carrier, the luggage carrier 11 can be folded. When only the pallet 10 is stored, the storage space of the pallet 10 can be reduced by folding and storing the loading platform.
When only the pallet 10 is carried, it can be carried easily by folding it. Therefore, by folding the loading platform 11, it is possible to facilitate the storage and handling of the pallet 10 even if it is a pallet for carrying large-sized packages or long packages. Further, it is possible to facilitate the handling work including the transportation and the transportation, facilitate the use of the pallet 10 many times, rather than making the pallet 10 disposable, make effective use of resources, and contribute to environmental conservation. In particular, a great effect can be achieved for a pallet for carrying large-sized packages and long packages.

When a plurality of pallets 10 are arranged side by side in the width direction, the abutting surfaces 44 of the abutting portions 36 are brought into abutment with each other to position the pallets 10 accurately and easily. Can be installed. This makes it possible to effectively use the space in both cases where only pallets are installed and when luggage is loaded and installed, and as many pallets as possible can be installed per unit space. Such installation work can be performed quickly and easily. Further, the pallet and the load are not installed in an undesired abutting state, and damage to the pallet and the load is prevented.

Further, the handle portion 29 can be touched, and an operator can manually carry the pallet. This makes it easier to carry the pallet. Further, for example, it is possible to carry a narrow passage or the like where a forklift, which is a vehicle for transportation, cannot travel, which is excellent in convenience. Moreover, in the present embodiment, the pallet 10, specifically, the loading platform 11 and the support legs 12a to 12d are formed using a paper material such as corrugated cardboard, so that it is easier to reduce the weight as compared with the case where a metal material is used. Thus, it is suitable for workers to carry by hand.

Further, the connecting portion 14 is reinforced by the reinforcing tape 30 to improve the strength against repeated folding and stretching of the loading platform and increase the number of times the pallet 10 is repeatedly used. This allows the resources to be used more effectively, and the pallet 10 has a simple structure called a girder type. Since the loading platform 11 is flat and has a girder configuration, the configuration for allowing the loading platform 11 to be folded and extended can be simplified. In the present embodiment, perforations 22 are formed on the luggage carrier body 20, and two reinforcing plates 21a and 21b are individually attached to both sides of the perforations 22, which is an extremely simple configuration. , Can be easily manufactured.

It can be transported using a forklift. When storing the pallet, the loading platform can be folded and stored. Further, when carrying only the pallet, the pallet can be folded and carried. This pallet is made of paper material by forming perforations on the loading platform, and is formed to be foldable and extendable by angularly displacing the loading platform around the connecting portion where the perforations are formed. be able to. The luggage carrier on which luggage is loaded is configured by attaching a reinforcing plate to each portion of the luggage carrier main body where the perforations are formed, with the perforations as boundaries. In this way, the luggage carrier main body is reinforced by the reinforcing plate to form the luggage carrier, and the luggage carrier can be formed of paper material with a simple structure and high strength, and can be folded and extended. Each support leg uses a cylindrical column, and this column, a C-shaped leg, and a reinforcing plate are assembled together. Each of the columns of each of the support legs is positioned by being fitted into a fitting hole formed in the reinforcing plate of the loading platform and a fitting hole formed in the base of the leg body, and the axis line is positioned at an accurate position. Placed vertically. Therefore, the strength is increased, and for example, a load of about 300 kg can be sufficiently supported. In this way, a pallet having a simple structure and extremely high rigidity can be realized by the paper material. Further, since the fitting holes of the loading platform for positioning the support columns are formed only in the reinforcing plate and do not penetrate the loading platform body, it is possible to form a flat loading surface in which no holes are formed in the loading platform. Further, the support legs are provided at intervals in the longitudinal direction of the luggage carrier, and the space between the support legs is open in the direction away from the luggage carrier.
With such a so-called girder type configuration, the loading platform is folded so that the loading surface is on the inside and the support legs are on the outside. Therefore, when stacking two folded pallets, The support legs of the other pallet can be stacked so as to fit between the support legs of the pallet. In addition, it is arranged at both longitudinal end portions of the cargo bed and an intermediate portion between both longitudinal end portions and at a position spaced from the connecting portion of the cargo floor at least by a distance larger than the longitudinal dimension of the supporting legs of the cargo floor.
Therefore, by arranging the one pallet and the other pallet so that the positions of the connecting portions are reversed, the pallets can be stacked in the same space as the longitudinal dimension of the loading platform of the folded pallet. This can increase the number of pallets that can be stored per unit space. In addition, the leg of each support leg has an abutting portion, and the outer surface of the abutting portion is formed to be the same or substantially the same as the end faces of the widthwise both sides of the luggage carrier. In addition, the support column is fitted in the fitting hole of the base portion connected to the contact portion and the recess of the support portion connected to the contact portion. By providing such a contact portion,
When a plurality of pallets are installed side by side in the width direction, the outer surfaces of the abutting portions are brought into contact with each other, whereby the pallets can be accurately and easily positioned and installed. This makes it possible to effectively use the space and install as many pallets as possible per unit space both when installing only pallets and when installing luggage. , Such installation work can be done quickly and easily. Further, the pallet and the load are not installed in an undesired abutting state, and damage to the pallet and the load is prevented.

According to the second aspect of the present invention, a reinforcing member that is attached to cover the perforations is provided at the connecting portion of each cargo bed portion. As a result, it is possible to reinforce the bed formed of the paper material and increase the strength against repeated bending.
