By simply pulling the free end side of the narrow fixing band portion 10 in this way, the wide winding band portion 2 can be strongly tightened.

  Except for the case where all of the fixing band portion 10 is folded at the time of the tightening, when the folding band portion 10 is folded halfway, the vertical length of the fixing band portion 10 is increased or decreased as compared with the winding band portion 2 due to the difference in length. Since the gap S is formed, there is a possibility that the tightened luggage may collapse from the gap (see FIG. 8).

  Therefore, the free end side of the auxiliary band portion 20 joined to the winding band portion 2 with the third and fourth hook-and-loop fasteners is peeled off, and the free end is opposed to the fixed end of the auxiliary band portion 20 as a base point. The outer side of the fixing band portion 10 is spread out in the folding direction of the fixing band portion 10 to cover the entire surface of the fixing band portion 10.

And since the free end 21 of the auxiliary | assistant band part 20 overlaps beyond the base end of the band part 2 for winding, it is respectively the overlap part of the free end of the auxiliary band part 20 and the base end side of the band part 2 for winding. The fifth and sixth hook-and-loop fasteners are joined so as to be peelable (see FIG. 9).
As a result, the upper and lower gaps S formed in the fixed band portion 10 are completely closed by the auxiliary band portion 20, so that the outer periphery of the stacked luggage 30 can be tightened with the same width as the winding band portion 2. it can.

[Usage of anti-loading band 2]
The load collapse prevention band 1 opens the auxiliary band portion 20 by folding the auxiliary band portion 20 outward from the fixed end when the outer peripheral size of the stacked cargo is large.
As a result, the tip of the auxiliary band portion 20 extends outward beyond the tip of the winding band portion 2, so that the auxiliary band portion 20 is used as an extension portion of the winding band portion 2 as shown in FIG. it can.

  That is, the auxiliary through hole 24 of the auxiliary gripping portion 23 provided at the free end 21 of the auxiliary band portion 20 is used in place of the through hole of the winding band portion 2, and the tip of the fixing band portion 10 is used as the auxiliary through hole 24. The second hook-and-loop fastener F2 and the first hook-and-loop fastener F1 of the fixing band portion 10 are joined to each other, and the stacked cargo can be fixed with the load collapse prevention band 1 tightened.

  Thereby, even if it is the outer periphery of the stacking load which cannot be tightened by the conventional usage, it is possible to extend the length of the outer periphery that can be tightened by extending the auxiliary band portion 20, and one load collapse prevention band 1. Can be used for two applications.

The shapes and attachment positions of the first surface fastener 13 and the second surface fastener 14 are not limited to the illustrated example, and can be appropriately designed so that they can be joined to each other when the fixing band portion 10 is folded back.
In this embodiment, the winding band portion 2 and the fixing band portion 10 are made of flexible materials, but may be made of a stretchable material for all or a part thereof.
In addition, it goes without saying that various design changes can be made without departing from the scope of the present invention.
