Description of the Related Art An ID tag is attached to an individual freight container in order to manage a freight container of a train, a freight currently loaded in the container, and a management of a transportation status of the freight container. Is being considered. The ID tag includes a sign unit (hereinafter simply referred to as a transponder) for storing a unique number, an identification code, and the like given to each cargo container as electronic information, a case for accommodating the transponder, and a case for the container. And means for fastening. Note that transponders are commercially available, and are widely used to prevent theft of displayed products in stores.

[0003] The sign information stored in the transponder can be read from the outer surface of the case by a dedicated reader in a non-contact manner. You can know the status of cargo transportation. The ID tag can be attached using the existing structure of the cargo container, and a loading frame for a destination display card at the bottom of the side wall of the cargo container can be used as an attachment target. By the way, as the loading frame, a metal plate frame obtained by press forming a steel plate and a plastic frame can be used, but it has excellent robustness when crushing and removing ice attached to the outer surface of the frame. In this respect, a frame made of a metal plate is frequently used.

[0004]

The ID tag needs to be attached to all cargo containers. Therefore, it can be easily attached to the loading frame without using tools, and once installed in the loading frame, the loading can be performed unless one of the mounting structure of the ID tag and the loading frame for the destination display card is destroyed. Simultaneously satisfying that it cannot be easily removed from the frame, and that the ID tag can be shared with both the metal loading frame and the plastic loading frame It is required to be able to do it.
However, some of the already proposed ID tags have not been able to satisfy all of the above conditions at the same time.

It is an object of the present invention to satisfy the above-mentioned conditions of use and, therefore, cannot be easily removed even though it can be easily installed without a tool. An object of the present invention is to provide an ID tag for a freight container that can be mounted in common. Another object of the present invention is to simplify the mounting structure of the ID tag, thereby reducing the cost of the ID tag. In addition, in the mounted state, the case can be fixed and held non-movably with respect to the loading frame. An object of the present invention is to prevent damage to a case due to shaking of a bogie and damage to a transponder.

[0006]

An ID tag according to the present invention comprises:
As shown in FIG. 2, the transponder 3 on which the sign information unique to the freight container is recorded, the case 2 containing the transponder 3, and the case 2 are fixedly mounted on the loading frame 1 for the destination display card provided on the outer surface of the container. Belt 4
Consists of The belt 4 is, as shown in FIG. 1 and FIG.
A retaining piece 13 provided on the connecting portion 12 on the belt free end side of the hooking portion 11. Case 2 has a connecting portion 1
2 and a connecting hole 9 for receiving the retaining piece 13 is formed. As shown in FIG. 5, the coupling hole 9 is provided with an engagement step portion 15 which engages with the retaining piece 13 to prevent the coupling portion 12 from coming off.

More specifically, the case 2 is suspended and fixed to the loading frame 1 by a pair of left and right belts 4. The belt 4 is made of a metal plate as shown in FIG. 4, and the retaining pieces 13 are formed in the connecting portions 12 at both ends by bending up so as to be elastically deformable. The inside of the connection hole 9 is divided into front and rear by a partition wall 16 so that
Are formed in the connection hole 9. Both locking holes 17.1 facing the front and rear surfaces of the partition wall 16
7 are provided on the front and rear walls, respectively, as shown in FIG.
Forming engagement step portions 15 which engage with 3.

[0008]

When attaching the ID tag to the loading frame 1 for the destination display card, one connecting portion 12 of the belt 4 is connected to the connecting hole 9 of the case 2 as described in the embodiment shown in FIGS.
And the retaining piece 13 is locked to the engaging step 15 inside the connecting hole 9. Next, the other end of the belt 4 is passed through the loading frame 1, and the hook portion 11 is bent and hooked on the loading frame 1 in an inverted shape (an inverted U-shape). Further, the connecting portion 12 on the free end side is inserted into the connecting hole 9 of the case 2, and the retaining piece 13 is locked to the engaging step 15 in the connecting hole 9. As described above, the belt 4 and the case 2 can be integrated inseparably by simply inserting the connecting portion 12 of the belt 4 into the connecting hole 9, whereby the case 2 is attached to the loading frame 1 by the belt 4. it can.

After the connecting portion 12 is inserted into the connecting hole 9 and connected, the retaining piece 13 comes into contact with and engages with the engaging step portion 15.
The connection portion 12 is prevented from coming out of the connection hole 9. Therefore, in order to remove the belt 4 from the case 2, the ID tag cannot be easily removed without cutting the belt 4 or the loading frame 1. The loading frame 1 made of a metal plate and the loading frame 1 made of a plastic are different in a thickness dimension and a width dimension of a frame portion to which an ID tag is attached. Therefore, if the length of the hook portion 11 of the belt 4 is properly set, the ID tag can be attached to any of the loading frames 1 by using one type of belt 4. Belts 4 of different lengths are loaded into each loading frame 1
Two types may be provided corresponding to the above, and may be properly used.

If a plurality of elastically deformable retaining pieces 13 are formed by bending up the connecting portions 12 at both ends of the belt 4 made of a metal plate, one of the retaining pieces 13 is engaged with the engaging step. Since the entire circumference of the hooking portion 11 of the belt 4 can be changed to be large or small by being brought into contact with the portion 15, the ID tag can be attached to different types of loading frames 1 using only one type of belt 4. Can be. The belt 4 can be shared similarly when a plurality of engagement step portions 15 are provided.

When the connecting hole 9 of the case 2 is divided into front and rear by the partition wall 16 and a pair of front and rear locking holes 17 are provided, the connecting portion in a state where one connecting portion 12 is inserted into the connecting hole 9 is provided. When the hanging portion 11 is mounted on the loading frame 1, it is possible to reliably prevent the previously connected retaining piece 13 from coming off the engagement step portion 15 by minimizing the play gap of 12. When the connecting portion 12 is inserted into each locking hole 17 and connected, the retaining piece 13 passes through the narrow portion 19 at the lower end of the locking hole 17 while being elastically deformed. When the tip of the retaining piece 13 enters the engaging step portion 15, the retaining piece 13 is displaced outwardly by its own elasticity and returns to a state exceeding the width of the locking hole 17. , The tip of which is received by the engagement step 15. Therefore, the connecting portion 12 inserted into the connecting hole 9 cannot be pulled out in a direction opposite to the inserting direction.

The engaging step 15 may be provided on any of the front and rear walls of the connecting hole 9 facing the partition wall 16 and the front and rear of the lower end face of the partition wall 16. It is preferable to adopt the former form from the viewpoint of mold durability.

If there is at least one belt 4, the case 2 can be mounted on the loading frame 1. However, when the case 2 is hung and fixed to the loading frame 1 using the pair of left and right belts 4, the case 2 can be attached to the case 2 loading frame 1 in a stable state, and a malicious second attempt to intentionally remove the case 2. The security effect against the three can be enhanced.

The belt 4 is prepared separately from the case 2, but if one end is fixed to the case 2 in advance as shown in FIG. 10, for example, the case 2 and the belt 4 can be handled in an integrated state. Therefore, the management of the ID tag before attaching to the loading frame 1 can be facilitated. When attaching the ID tag, it is also advantageous in that the labor for connecting one end to the case 2 can be omitted and the attaching operation can be performed more quickly. The belt 4 can be inserted and fixed at the time of molding the case 2 or a screw 21 for fixing the back cover 6 of the case 2.
And can be integrated with the case 2.

The retaining piece 13 can be formed as a separate component from the belt 4. In this case, the belt 4 can be formed of a metal plate, plastic, or a composite plastic material in which wires are embedded, and the material for forming the retaining piece 13 can be formed of a material such as metal or plastic.

Although the retaining piece 13 passes through the narrow portion 19 by being elastically deformed against its own elasticity, the same function can be exerted by swingably supporting the retaining piece 13. In this case, as shown in FIG. 12, the retaining piece 13 is moved and urged by the spring 25, whereby the retaining piece 13 that has passed through the locking hole 17 is oscillated and disengaged from the engagement step portion 15. And maintain that condition.

The step depth (width in the front-rear direction) of the engaging step 15 is E
Is set equal to or slightly smaller than the cut-and-raised dimension T in the free state of the retaining piece 13. In a state in which each connecting portion 12 is inserted and connected to each locking hole 17, the connecting portion 12 is prevented from moving in the thickness direction, and the retaining piece 13 is reliably prevented from falling off from the engaging step portion 15. That's why. The lower end of each locking hole 17 facing the engaging step portion 15 is set in a narrow portion 19, and the gap M before and after the narrow overflow portion 19 is set to 1.5 to 3.0 times the thickness of the connecting portion 12. When the connecting portion 12 is inserted into the connecting hole 9 and is engaged when the connecting portion 12 is set back and forth,
The retaining piece 13 can be passed through while being elastically deformed toward the plate surface side of the connecting portion 12. The vertical length of the pilot hole 9b is set so that the free end of the connecting portion 12 is not exposed to the lower side of the case 2 when the ID tag is mounted on the loading frame 1.
