Description

[Detailed description of the invention] Industrial application field This invention relates to a box pallet used mainly for transporting and storing agricultural products such as mandarin oranges, onions, and horseradish.

Conventional technology Conventionally, this type of box palette has been developed since its inception.
There is one as shown in Japanese Patent No. 52-139261.
This known box pallet is constructed by pivoting the lower edge of the rear end of an enclosing structure comprising frame plates on four sides, front and rear and right and left, constituting a peripheral wall, to the rear edge of a flat pallet constituting a bottom plate. By tilting the box pallet downward with respect to the surrounding structure, the front bottom of the box pallet can be opened and the contents can be discharged by gravity. It is attracting attention as a thing.

Problems to be Solved by the Invention However, in the above-mentioned conventional product, since the surrounding structure that constitutes the peripheral wall is constructed by welding the front, left, and right frame plates to each other, when not in use, That is, even after the contents have been discharged, the pallet occupies a large volume, which is disadvantageous when transporting and storing the empty pallet.

Therefore, this invention maintains the functionality of discharging the contents as described above to the same level as conventional products, while
To make the transportation and storage of empty pallets even more advantageous, the surrounding structure can be folded onto the flat pallet at the bottom, and the surrounding frame plates can be folded when not in use. The object of the present invention is to provide a box pallet which can be made compact and which also allows a plurality of box pallets to be stacked stably in this folded state.

Means for Solving the Problems This invention has been developed for the above-mentioned purpose in a box pallet in which frame plates 2, 3, 4, 5 on the front, rear, left and right sides, which form the peripheral wall, are erected on a flat pallet 1. On both front and rear edges of flat pallet 1,
The front horizontal beam 6 and the rear horizontal beam 7 are placed on the flat pallet 1 without being fixed, and the rear surface of the rear horizontal beam 7 is pivotally connected to the rear surface of the pallet 1 with hinges 10, 10. Bearing pieces 8 are provided at both ends of the crosspiece 7, respectively.
8 are fixed upright, and a pair of left and right shaft rods 9, 9 are respectively fixed between both ends of the front horizontal beam 6 and the bearing pieces 8, 8, and the left and right frame plates 4, 5 are fixed. The lower end is pivotally supported by the shaft rods 9, 9, so that the rear frame plate 3 can be folded inwardly. Differently, the lower end is pivotally supported by a rear shaft rod 11 which is fixed to the horizontal frame, so that the front frame plate 2 can be folded inwardly. The peripheral frame 4a of the other frame plate is mounted on the top of one of the adjacent frame plates 2, 3, 4, and 5 on the four sides. Frame plate connecting fittings 12, which can be hung and removed freely, are attached to 5a and 3a, and furthermore, on the left and right side edges of the flat pallet 1, the frame plates 2, 3, 4, and 5 have a thickness slightly higher than that when folded. Fixed side wall plate 16,1
6 is provided.

A pair of bearing pieces 8, 8 each having an L-shaped cross section are fixed in an upright position. The bearing pieces 8, 8 are located slightly inwardly on both rear corners of the flat pallet 1, and their lower ends are attached to the rear corners of the flat pallet 1 in a covered manner. It is supported in contact with a molded reinforcing plate 14.

A pair of left and right shaft rods 9, 9 are horizontally fixed in parallel between both ends of the front horizontal beam 6 and the bearing pieces 8, 8, respectively. And this double shaft rod 9,9
The left and right frame plates 4 and 5 are rotatably pivoted by fitting the lower sides of the pipe peripheral frames 4a and 5a, respectively, so that they can be folded inward.

Further, between the bearing pieces 8, 8, a rear shaft rod 11 is horizontally fixed at a height different from the left and right shaft rods 9, 9 by at least the thickness of the left and right frame plates 4, 5. The rear frame plate 3 is pivotally attached to this by fitting the lower side of the peripheral frame 3a so as to be able to freely fall inward.

On the other hand, the front frame plate 2 is configured such that the lower end of the peripheral frame 2a is simply placed on the front horizontal beam 6 in a supported state, and can be removed therefrom. However, since the front horizontal beam 6 is made of an angle material, it is prevented from coming off in the forward direction. In addition,
The front frame plate 2 may also have its lower end pivotally attached to the front horizontal beam 6 so as to be rotatable and fallable.

The front frame plate 2 includes left and right frame plates 4, as shown in FIG.
Furthermore, the rear frame plate 3 is positioned on the rear side of the left and right frame plates 4 and 5. A frame plate connecting fitting 12 having a hook rod 12a that can be freely hooked and detached from the vertical part of the peripheral frame of the other frame plate is attached to the upper side edge of one of the two adjacent frame plates, It is designed so that the plates can be fastened together. That is, in the illustrated embodiment, the frame plate connecting fittings 12 are attached to the upper parts of the left and right edges of the front frame plate 2 and the upper parts of the rear side edges of the left and right frame plates 4 and 5, respectively. The rear parts of the left and right frame plates 4, 5 can be firmly connected to the front parts of the frame plates 4, 5 and the rear parts of the left and right frame plates 4, 5 to both sides of the rear frame plate 3 in a separable manner. The above-mentioned connecting fitting 12 is of a conventionally known type (for example, Japanese Utility Model Publication No. 18146/1983), which is capable of controlling the forward and backward movement of the horizontally oriented hook rod 12a by raising and lowering the operation plate 12b.

In addition to when the front frame plate 2 is stood vertically,
In order to enable the left and right frame plates 4 and 5 to be installed in an inclined manner, one or more inclined engagement rods 15 are provided at the upper front end portions of the left and right frame plates 4 and 5 at positions corresponding to the frame plate connecting fittings 12 that they have. , 15 are attached, and by selectively engaging the hook rods 12a of the connecting fittings 12, the front frame plate 2 can be fixed inwardly in any inclined state, as shown in FIG. It is said to be useful.

Fixed side wall plates 16, 16 are fixed to the resulting projecting portions of both side edges of the flat pallet 1. The side wall plates 16, 16 are made by bending metal plates such as iron plates to have a substantially square cross section, and the four side wall plates 2, 3, 4, 5
It is provided over almost the entire length of the flat pallet 1, and is slightly higher than the thickness when folded. Further, this side wall plate 16 is firmly fixed to the flat pallet 1 with suitable screws, etc., and short pipes 17, 17 made of pipes for inserting supporting legs are welded and fixed to both ends of the plate between the upper and lower horizontal parts. , the top surface of the side wall plate 16 is opened at the short pipe attachment part, and an insertion support leg 2 is fixed to both ends of a cargo spill prevention plate 18 made of plywood or the like through reinforcing strips 19, 19.
By inserting screws 0 and 20, the cargo spill prevention plate 18 can be detachably attached. The spillage prevention plate 18 is for preventing the contents from spilling over the side edges of the flat pallet 1 when the contents are discharged downward.
Corresponding to the open state of the bottom surface when taking out stored items, the width is formed to be wide at the front end and narrow toward the rear end.

Effects of the Embodiment The box pallet described above is used for storing and transporting oranges and the like. Insert the fork into the fork insertion hole and lift the entire frame to the required height, for example, by hooking the upper end of the rear frame plate 3 to the vehicle body side of the forklift using an appropriate hook, etc. After ensuring that the plates 2, 3, 4, and 5 do not tilt, the forks are swung forward and downward. Then, as shown in Fig. 3, only the flat pallet 1 part tilts downward around the hinge 10 and opens between it and the front frame plate 2, so that the stored items naturally flow down from the opening and are discharged. be given On this occasion,
The side wall plates 16, 16 and the spillage prevention plate 18 are
It serves to prevent stored items from spilling to the sides.

If the empty box pallets from which the contents have been discharged are to be transported back or stored, they can be folded and stacked as shown in FIG. 13. In this folding operation, first, the frame plates are uncoupled from each other by the frame plate connecting fittings 12, and then, for example, the front frame plate 2 is removed, and then the left and right frame plates 4, 5 are placed on the flat pallet 1 by the shaft rods 9, 9. The rear frame plate 3 is folded in order around the center, and the rear frame plate 3 is folded on top of it centering on the shaft rod 11, and the front frame plate 2 is placed on top of it.
