Description

  The present invention relates to a sheet pallet, and more particularly to a structure of a tray-like sheet pallet.

The sheet pallet is a pallet used for transporting cargo by a forklift equipped with a push-pull device, and is thin and lightweight, so that it can be handled alone and has high loading efficiency. In addition, the use efficiency of the storage space is high.
The sheet pallet is often a flat plate having a foldable tab for gripping with a gripper at one end. However, when loading and unloading and transporting a load, the sheet pallet is likely to collapse due to a sudden stop or vibration. Therefore, a tray-like sheet pallet is often used in which a fold is provided in the peripheral portion of the sheet to form a side wall piece, an end wall piece, and a tab, and this is raised.

  In this sheet pallet, generally, a side wall piece and an end wall piece are raised, and corners are connected by a metal stable. However, this metal fitting is troublesome because it is required to be removed at the time of disposal. Therefore, such a device has been developed in which both ends are engaged with each other without using a metal fitting (Patent Document 1, Patent Document 2).

In the sheet pallet of Patent Document 1, a bent piece is provided at one end of the side wall piece and the end wall piece, a through hole is formed in the extending piece extending to the other end adjacent thereto, and the bent piece is attached to this. Inserted, bent and joined. As another invention, an extended piece having an enlarged portion at the tip is provided at one end of the side wall piece and the end wall piece, and is sewn into two slit-shaped through holes provided at the other adjacent one end. Insert and join.
In addition, the sheet pallet of Patent Document 2 is formed by extending a bent piece formed with a cut at one end of the side wall piece and the end wall piece, and engaging this with a cut formed at the other adjacent end. Yes.

Along with extending the piece, a plurality of vertically long locking holes are provided near the end of the end wall piece adjacent to the insertion piece, and the insertion piece is inserted from the inside of the locking hole near the corner. The insertion piece is inserted from the outside of the next locking hole, or the insertion piece is inserted from the outside of the locking hole near the corner and inserted from the inside of the next locking hole for coupling. Is provided with a head longer than the length of the locking hole at the tip of the trunk, and is provided with a fold g obliquely from the neck to the head so that the tip narrows when folded and can be inserted into the locking hole. Is provided with a fold f for folding in a direction perpendicular to the longitudinal direction.

This tray-like sheet pallet can be removed into a sheet shape if necessary. The sheet pallet is preferably made of cardboard.
The insertion piece has a head longer than the length of the locking hole, and the fold g is inclined diagonally from the neck to the head so that the tip can be folded and the locking hole can be hidden by folding the head part. Provide.
The locking holes are vertically long when the end wall piece is raised, and a plurality (2 to 3) of the locking holes are provided near the end.

Further, as described in claim 2, it is preferable that the plurality of locking holes have the same longitudinal length and are slightly longer than the length in the direction perpendicular to the longitudinal direction of the body portion of the insertion piece. Desirably, the locking holes have the same shape as described in claim 3, and the locking holes to be inserted last make the escape grooves 7 a easy to come off when the head of the insertion piece is folded. Form.
It should be noted that both side wall pieces are preferably provided with a 45-degree crease m from the lower end of the end wall piece to the upper end of the side wall piece so that it can be folded into a sheet shape when not in use while being connected in a tray shape (claim) Item 4).

  The seat pallet of the present invention extends the insertion piece to the side wall piece, and provides a plurality of vertically long locking holes near the end of the end wall piece adjacent to the insertion piece. The insertion piece has a head longer than the length of the locking hole at the tip of the body, and the tip narrows when folded and inserted into the locking hole. Since the fold line g is provided obliquely from the neck to the head side and the body part is provided with a fold line f for folding in the direction perpendicular to the longitudinal direction, the work is simple and strong. In addition, the coupling can be released by a simple operation of folding from the crease g and removing from the locking hole.
