As shown in FIGS. 1, 2, and 5, the stacking jig 10 includes a support member 11. The column member 11 includes two flat portions 12 that abut each side plate 52 in the corner portion 51 of the cardboard box 50, and the column member 11 is formed in a substantially L-shaped cross section as a whole.

A reinforcing member 13 is integrally formed at one end of the column member 11. The reinforcing member 13 includes an outer wall portion 14 having a width dimension slightly longer than the width dimension of the planar portion 12 of the column member 11 and a thickness dimension slightly larger than the thickness dimension of the planar portion 12.
In addition, a support portion 15 that protrudes substantially perpendicular to the inner surface is formed on the inner surface of the outer wall portion 14.
An inner wall portion 16 having a predetermined gap with respect to the outer wall portion 14 and extending substantially parallel to the outer wall portion 14 is integrally formed at the distal end portion of the support portion 15.
The outer wall part 14, the support part 15, and the inner wall part 16 are formed in a substantially U shape in a side view.

The gap dimension between the inner surface of the outer wall portion 14 and the inner surface of the inner wall portion 16 is a thickness dimension in a state in which the lid 53 of the cardboard box 50 is bent so as to open until it contacts the side plate 52 of the cardboard box 50, that is, The thickness of the side plate 52 of the cardboard box 50 and the thickness of the lid 53 are formed to be approximately the same as the total dimension.
Further, the length dimension from the inner surface of the support portion 15 to the tip of the column member 11 is longer than the depth dimension of the cardboard box 50 and is longer than the length dimension of the lid 53.

As shown in FIGS. 2 and 3, the inner wall of the outer wall portion 14 has a plurality of (three in the present embodiment) return portions 17 having a cross-sectional shape formed in an acute angle width of the outer wall portion 14. The protrusion is formed so as to extend in the direction.
Further, the bundling formed on each flat surface portion 12 at a position corresponding to the corner 51 of the cardboard box 50, that is, in the vicinity of the corner 19 of the column member 11, which is a substantially intermediate portion in the length direction of the column member 11. A binding hole 18 is formed as a part.
The binding hole 18 may be formed so as to protrude to the outside of the column member 11.

The stacking jig 10 is integrally formed of a resin material such as polypropylene, for example. By using a resin material, sufficient strength can be secured to support the cardboard box 50.
Of course, for example, a metal material other than resin may be used, but a resin material is more preferable because it is excellent in moldability and weight reduction.

Since the stacking jig 10 configured as described above is mounted on each corner 51 of the cardboard box 50, the four stacking jigs 10 are configured as one set.
In the present embodiment, as shown in FIG. 4, one string-like member 20 as a binding member is inserted into the binding hole 18 of each stacking jig 10.
Thus, by inserting the string-like member 20 into the binding hole 18 of the four stacking jigs 10, the four stacking jigs 10 can be handled integrally, and each stacking jig 10 can be handled. The tool 10 does not fall apart, and the handleability can be improved.
Further, the string-like member 20 is inserted from the outside into one binding hole 18 of each support member 11, passes through the inside of the corner 19 of the support member 11, and comes out from the other binding hole 18. Is inserted as follows.

As a result, when the stacking jig 10 is mounted on each corner 51 of the cardboard box 50 and tightened by the string-like member 20, each flat member 12 is tightened so as to be pressed from the outside. It becomes possible.
As the string-like member 20, for example, any known rope or the like may be applied. Moreover, you may apply the string-like member 20 which has a stretching property, for example.
Furthermore, the string-like member 20 may be, for example, a round cross-sectional shape or a flat cross-sectional shape. However, a round cross-sectional shape is more preferable because it is not necessary to consider twist.

A fastening member 21 for fastening both ends of the string-like member 20 and fastening the string-like member 20 is attached to the end of the string-like member 20. As the fastening member 21, for example, a member using a ratchet mechanism is suitable.
The ratchet mechanism is configured to rotate in the tightening direction of the string-like member 20 when the string-like member 20 is inserted, but does not rotate in the reverse direction until the ratchet mechanism is opened, and therefore pulls the string-like member 20. Only by this, the string-like member 20 can be easily tightened. In particular, when a ratchet mechanism is used, since the tightening force is strong, each stacking jig 10 can be firmly fixed.
In this case, when the string-like member 20 is tightened, the tip of the string-like member 20 may remain, so it is preferable to attach the hook 22 to the tip of the string-like member 20.
If comprised in this way, it can prevent the drooping of the excess string-like member 20 by hooking the hook 22 on the clamped string-like member 20. Therefore, the string-like member 20 does not get in the way, and safety and workability can be improved.
The fastening member 21 is not limited to the one using the ratchet mechanism. For example, a buckle through which the string-like member 20 is inserted, a universal bracket that can fix the string-like member 20 at an arbitrary position, or the like. Any member may be used as long as the string-like member 20 can be tightened.

Next, the operation of this embodiment will be described.
First, a procedure for mounting the stacking jig 10 will be described.
As shown in FIG. 6, parts necessary for manufacturing are usually delivered in a state of being packed in a cardboard box 50.
When using parts, the lid of the cardboard box 50 is opened, and the lid 53 of the cardboard box 50 is opened until the lid 53 contacts the side plate 52 of the cardboard box 50.
In this state, when the length of the lid 53 is longer than the depth of the cardboard box 50, the tip of the lid 53 (the lower end when the lid 53 is opened) is the cardboard box 50. Since the cardboard box 50 is supported only by the lid 53, it is extremely difficult to stably support the cardboard box 50.

Therefore, the stacking jig corresponds to the height dimension of the largest cardboard box 50 so that it can be used for the largest cardboard box 50 corresponding to the height dimension of the cardboard box 50 used. The length dimension of the tool 10 may be set.
In this case, a stacking jig 10 having a single size may be used, or a plurality of stacking jigs 10 that match the size of the cardboard box 50 may be prepared. Further, only a stacking jig 10 having a length dimension adapted to the largest corrugated cardboard box 50 is prepared, and the column member 11 of the stacking jig 10 is cut according to the size of the cardboard box 50. By doing so, you may make it utilize.

Further, the entire circumference of the cardboard box 50 also changes depending on the size of the cardboard box 50, but the length dimension of the string-like member 20 so as to correspond to the entire circumference of the cardboard box 50 of the largest size. Should be set.
In the present embodiment, since the hook 22 is provided on the string-like member 20, the surplus string-like member 20 does not get in the way.

As described above, in the embodiment to which the present invention is applied, the supporting member includes the support member 11 that is bent in the L-shaped cross section and covers the outside of the corner 51, and the outer wall 14 and the inner wall 16. 15 and a reinforcing member 13 having a U-shaped cross-sectional shape. The lid 53 of the cardboard box 50 is bent outward and the reinforcing member 13 is inserted above each corner 51 of the cardboard box 50. In this state, the length dimension from the support portion 15 of the reinforcing member 13 to the tip of the column member 11 is longer than the depth dimension of the cardboard box 50 and has a length equal to or greater than that of the lid body 53.
According to this, the length dimension from the support part 15 of the reinforcement member 13 to the front-end | tip of the support | pillar member 11 is longer than the depth dimension of the cardboard box 50, and it forms so that it may have the length more than the cover body 53. Thus, the cardboard box 50 can be reliably supported by the support member 11 of the stacking jig 10 without supporting the cardboard box 50 only by the lid 53. As a result, the cardboard box 50 in which the parts are packed can be used as it is as a parts container, so that the part replacement work is not necessary and the work efficiency can be improved.
