Description

[Detailed Description of the Invention] The present invention relates to a luggage fastening device for freight cars and the like. Conventionally, as shown in Figure 2, in this type of tightening device, a recess was created by cutting out a recess in the floor surface, and the circular ring 3 was fixed in the recess so that it could be raised and lowered, so once the ring was damaged, it had to be replaced. The work was not easy. Furthermore, the mounting position of the above-mentioned fasteners has been restricted due to the relationship with the floor joists.

The present invention improves the above drawbacks and will be described in detail below with reference to the drawings.

FIG. 1 shows a state in which a load 1 is placed on a loading platform 4 and tightened with a rope 2, and the end of the rope 2 is tightened with a tightening device 3. Since this configuration has the above-mentioned problems, this is an improvement.

Referring to FIG. 3, reference numeral 5 denotes a side frame member of the loading platform, which has a cross-sectional shape, to which side fans 6 and the like are attached. Reference numeral 7 denotes a reinforcing member attached to the inner surface of the side frame member 5 at a suitable position in the longitudinal direction, and has a similar shape to the side frame member 5. A tightening tool 8 is attached to a portion of the side frame member 5 to which the reinforcing member 7 is fixed. 9, 9 is the side frame material 5
A hole is drilled through the reinforcing member 7 to form an upper receiving portion 5a of the side frame member 5, and the leg portion 8b of the tightening device 8 is inserted through these two holes and attached. .

As shown in FIG. 5, the tightening tool 8 has a leg portion 8b of a shaped main body, and a hook portion 8c that is substantially perpendicular to the leg portion 8b and facing in the same direction is connected to the lower end of the leg portion 8b. 8d (Fig. 6) is a projection provided downward on the horizontal portion 8a of the tightening device, on which a ring 2a provided at the end of the rope 2 can be hooked.

Now, the leg 8b of the tightening tool is attached to the upper receiving part 5a of the side frame member 5.
The legs 8 of the tightening tool 8 are inserted into the two holes 9, 9 with a width of
b is inserted through the hook portion 8c and attached (FIG. 7). When the tightening tool 8 is not in use, it is dropped down from the upper receiving portion 5a into the side frame member 5 and stored (FIG. 8). When in use, the upper horizontal portion 8a of the tightening tool is pinched and lifted. In addition, if there is a downward protrusion 8d as shown in Fig. 4, there are three 9, 9, 9 on the receiving part.
a (Fig. 9) and insert the central protrusion 8 into the central hole 9a.
d and store it.

According to the present invention as described above, 1. Since the fastening tool 8 is made detachable from the receiving part 5a, if the fastening tool is damaged, it can be immediately replaced with a new one.

2 In addition, the structure is simple and can be easily applied to existing freight vehicles because the tightening device 8 can be attached by simply fixing the reinforcing member 5 to the side frame material 5, joist, etc. and drilling a hole 9 in the upper surface of the reinforcing member 5. There are advantages that can be applied.

3. Since it can appear and retract from the loading platform 4, it will not cause any discomfort during cargo handling operations.

4 By providing the protrusion 8d on the tightening tool 8, it can be hooked onto the rope 2 instantly.
