DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load-tightening fastener for fixing a rectangular box containing a variety of articles so as to prevent the rectangular box from collapsing when the box is transported.

[0002]

2. Description of the Related Art Conventionally, in order to prevent the collapse of a rectangular box, a plurality of stacked loads are arranged along the outer edge between the rectangular box above and below the rectangular box which contacts the upper and lower sides of an appropriate height. Around the cargo, a piece of gum tape was stuck, and the upper and lower rectangular boxes were connected to fix the load.However, when the gum tape was removed, the box surface became dirty, In the case of this box, the box surface is peeled off, and the printed characters and patterns on the box surface are also peeled off. Also, the peeled gum
Tapes cannot be used again, become garbage, hinder the environment and waste resources.

Accordingly, the present inventor has already filed a Japanese Patent Application Laid-Open No. 9-20337 for a fastener for preventing collapse of a rectangular box. According to the present invention, as shown in FIG. 6, an abutment bent into a substantially L-shaped cross-section composed of two pieces 20A, 20A sandwiching a right angle so as to contact both sides of the rectangular box with the corners on the sides of the rectangular box interposed therebetween. At the same time, vertically long holes 20B are formed near both side ends of the plate 20,
A horizontal insertion piece 20C to be inserted between the upper rectangular box and the lower rectangular box, which are vertically adjacent to each other, is provided substantially in the vertical center of the mounting plate 20 inside the mounting plate 20. And
The band-shaped body 21 is inserted into one of the vertically-long holes 20B from the one vertically-long hole 20B of the attachment plate 20 and is inserted into the other vertically-long hole 20B. At one end of the band 21, a vertically elongated ring 23 through which the other end of the band 21 is inserted is provided, and at the other end of the band 21, a pull portion 24 is provided. And a hook-and-loop fastener 26 that adheres to the hook-and-loop fastener 25 so that it can be separated from the hook-and-loop fastener 25 when folded back at an interval from the hook-and-loop fastener 25.

[0004]

According to the prior art having the above structure, the contact plate 20 having an L-shaped cross section is heavy and bulky when folded, it is difficult to store the contact plate, and the contact portion is a corner on the side surface of the rectangular box. Is limited to When the insertion piece 20C is inserted between the upper and lower rectangular boxes, if the height of the upper rectangular box is low, the upper part of the strip 21 may protrude from the rectangular box. Further, since the fastening device is formed by bonding the hook-and-loop fasteners 25 and 26 to each other, there is a problem that the bonding function is deteriorated when used for a long period of time, and dirt and the like adhere to the hook-and-loop fasteners 25 and 26 and are easily stained.

[0005] In view of the above, the present invention makes it easy to wind a belt-shaped body wound around a plurality of stacked rectangular boxes to prevent collapse of the load on the rectangular box, to secure the fixing, and to secure a long time. It is an object of the present invention to provide a fastening device for preventing the collapse of a rectangular box, which does not deteriorate the function of the fastening device even when used.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to an inner surface of a contact plate having a vertically extending elongated hole on both sides, which can be turned upside down with respect to the plate surface of the contact plate. The insertion member is rotatably pivoted, a band is inserted through one long hole of the contact plate along the outer surface of the contact plate into the other long hole, and one of the band members is At the end, a fastening plate having a long hole on the front side through which the other end of the belt-shaped body is inserted is provided, and a lever is provided on the outer surface of the fastening plate on the base end side of the fastening plate. A hooking rod that is fixed so that it can be turned up and down to the left and right with respect to the plate surface, shifts the position of this fixing portion, and hooks and folds the belt-shaped body inserted through the long hole of the fixing plate near the fixing portion of the lever Characterized in that the base portion is mounted so as to be rotatable in the horizontal direction, and a stopper for preventing return of the lever is provided on the outer surface of the fastening plate. A. Further, in the present invention, it is preferable that the strip has a non-slip portion.

In use of the present invention having the above-mentioned structure, first, when the insertion plate of the contact plate is raised, the rectangular pieces are stacked above and below the appropriate height position of the stacked rectangular boxes, or between the appropriate rectangular height boxes. The insertion piece is inserted between the rectangular boxes adjacent to each other at the horizontal position, but when inserting it between the upper and lower rectangular boxes, the insertion piece is turned so that it goes up and down When inserted between rectangular boxes adjacent to each other horizontally, the inserted pieces are pivoted so as to be turned up and down in the left-right direction.

[0008] By inserting the insertion piece between the rectangular boxes, the contact plate is stably attached to the side surface of the rectangular box. Next, holding one end of the band, make a round around the stacked rectangular box, and attach the other end of the band to the long hole of the fixing plate provided at one end of the band. Insert it from the inside, hook it on the hook of the fastening plate, turn it back, insert it again through the long hole from the outside,
By holding the tip and pulling it in the folded direction with one hand, the lever inclines to the inner surface of the fastening plate with the movement of the hooking rod, and the band is tightened and fixed. Further, since the band-shaped body has the non-slip portion, it does not shift.

Next, by locking the tilted lever with the stopper for preventing return, the lever is fixed, and the hooked rod does not return, so that secure fastening is possible. And
When removing the band, the locking of the stopper for preventing return is released, and when the lever is raised, the hooking rod returns, and the band is loosened and easily comes off.
