Abstract

PURPOSE:To eliminate the possibility of damages being done to an article due to the underhang or overhang by making either or both of deck board and beam freely expandable and contractible within a predetermined range. CONSTITUTION:Either or both of beam stopper 9 and deck board stopper 11 act on either or both of beam 3 and deck board 4 at the places with which a beam expansion and contraction mechanism 5 and a deck board expansion and contraction mechanism 6 are engaged in order to engage these stoppers 9 and 11 with the edges of the beam 3 and the deck board 4, whereby the stretched condition of the expansion and contraction mechanisms 5 and 6 can be retained. Conversely, in the case of contraction of the beam 3 and the deck board 4, by forcing inwards the expansion and contraction mechanisms 5 and 6, the expansion and contraction mechanisms 5 and 6 can be inserted into the beam 3 and the deck board 4. Therefore, since the deck board on a pallet is dimensionally adjustable easily to conform with the dimension of articles to be stacked thereon, the damages done to the article caused by the underhang or overhang can be reduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to pallets used for smoothly and rationally carrying out logistics activities such as transportation, storage, and cargo handling of goods. It concerns a palette that can be varied within a range.

[Conventional technology]

Conventionally, pallets used for logistics activities such as transporting, storing, and handling goods are usually shaped and structured in accordance with JIS standards, for example, as shown in the perspective view shown in Figure 8. There are wooden child pallets that comply with JIS Z0604.

In the figure, (1) is a palette, (3) is a digit, (4
) is a deck board, and the pallet (1) includes the deck board (4) on which the goods (8) are placed, and the deck board so that a loading device, such as a fork of a forklift, can be inserted into the bottom surface of the deck board (4). It is formed by fixing (4) and girder (3) to each other.

Since both the girder (3) and the deck board (4) are made to specific dimensions, the dimensions of the deck board (4) of the pallet (1) formed by fixing the two, that is, the size of the item (8) The mounting space on the deck board (4) for mounting is fixed and unchangeable.

Items (8) are placed on the deck board (4) of the pallet (1) above.
), the dimensions of the item (8) and the dimensions of the deck board (4) may not necessarily match.
Even if the product does not comply, the reality is that it is used for logistics activities such as transportation, storage, and cargo handling in a non-compliant state.

[Problem to be solved by the invention]

However, according to the above-mentioned bullet (1), if the dimensions of the item (8) are larger than the dimensions of the deck board (4) (overhang), the item (8)
4) If there is a bullet that protrudes from the top or a bullet like this (
When items 1) are stacked, there is a problem in that the items (8) on the lower tier are likely to collapse due to crushing. Conversely, if the dimensions of the item (8) are smaller than the dimensions of the deck board (4) (underhang), not only will the surface utilization rate of the bullet (1) be reduced, but also the deck board (4) will In many cases, dunnage (stuffing) is used to prevent the item (8) from moving, resulting in a decline in transportation efficiency, storage efficiency, and work efficiency, and in the worst case, deck board (4) There was a problem that the item (8) above would collapse. Furthermore, since it is not easy to assemble and disassemble the valet (1), there is also the problem that securing a storage space when storing the valet (1) and repair work when the valet (1) is damaged becomes extremely complicated.

The second invention was made to solve the above-mentioned problems, and aims to provide a valet that is compatible with the dimensions of the unit load product and has excellent storage and repairability. purpose.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a valet for placing items, which is formed from a deck board and a girder that intersects with the deck board and is disposed on the lower surface side of the deck board. The deck board and the girder are not fixed to each other, and the deck board, the girder, or both are configured to be expandable and contractible within a predetermined range.

Here, in the above bullet, the relationship between the deck board and the girder is such that the legs through which the girder passes are fixed to the lower surface of the deck board, and preferably, the ends of the girders located at the corners of the bullet prevent the deck boat from falling off. Fix the board. In addition, the deck board and the girder are not fixed to each other, but the protrusion provided on the lower surface of the deck board is loosely inserted into the groove formed on the upper surface of the girder at their intersection point, and the deck board is attached to the deck board. Configure the digits so that they can slide. Moreover, configuring the deck board to be extendable means that it includes a plurality of deck boards, a plurality of deck board extension mechanisms arranged in the deck board cabinet and supported by an elastic material in a removable manner, and a plurality of deck board extension mechanisms arranged at predetermined intervals in the deck board extension mechanism. This means that the deck board is formed by a plurality of deck board stoppers that can be engaged and detached at the end of the deck board when the deck board expansion/contraction mechanism is inserted into and removed from the deck board. Furthermore, configuring the digits to be expandable and retractable means that the digits are configured to have a plurality of digits, a plurality of digit extensible mechanisms disposed within these digit cabinets and supported removably by an elastic material, and a plurality of digit extensible mechanisms formed in the digit extensible mechanisms and the same. This means that it is composed of a plurality of digit stoppers that can be engaged and detached at the digit ends when the digit expansion/contraction mechanism is inserted into and removed from the digit.

[Effect]

According to this invention, since the deck board, the girder, or both are configured to be expandable and retractable within a predetermined range, the dimensions of the deck board, that is, the size of the item to be placed on the deck board, or the size of the item to be placed on the deck board, The mounting space for this can be increased or decreased within a predetermined range. Therefore, since the item can be placed on the barrette after adjusting the dimensions of the deck board to the placement space according to the size of the item, damage to the item due to underhang or overhang can be eliminated. In addition, the deck boat and the girder are not fixed to each other, and the girder is simply supported crosswise with the deck board by the legs provided on the underside of the deck board, so it is easy to assemble and disassemble the deck boat and the girder, as described above. Since the dimensions of the bullet are expandable and retractable within a predetermined range, the storage space for the bullet is small, and repair work when the bullet is damaged can be easily and easily performed.
