The fixing surface 12b on the other side is a rectangular plate member having the same shape as the fixing surface 12a on the one side. be.

In addition, as shown in FIG. 1, holes are formed in the other side fixing surface 12b, and similarly to the one side fixing surface 12a, the struts 6 and 7 are attached using fastening members such as bolts and nuts. can be fixed to

As shown in FIGS. 1 and 2B, the other-side extending surface 14b is provided so as to be orthogonal to the other-side fixing surface 12b, and has a rectangular shape having the same shape as the one-side extending surface 14a. It is a plate member. The other-side extending surface 14b has, for example, a longitudinal length of 80 mm and a lateral length of 19 mm.

As shown in FIGS. 1 and 2(b), the other side locking surface 16b is provided so as to be orthogonal to the other side extending surface 14b, and has the same shape as the one side locking surface 16a. It is a shaped plate member. That is, the other locking surface 16b is provided substantially parallel to the other fixing surface 12b.

In addition, as shown in FIGS. 1 and 2(a), the other locking surface 16b is formed with a recess 18a with which the end of the fall prevention bar portion 8 can be locked. The recess 18a is a notch with a width of approximately 11 mm and a depth of approximately 15 mm.

Furthermore, as shown in FIGS. 1 and 2(a), the drop prevention bar portion 8 is formed with a long hole portion 20a on the one side locking surface 16a. The elongated hole portion 20a has a width of approximately 11 mm and a length of approximately 50 mm in the longitudinal direction.

That is, the anti-fall bar fixing portion 10a on one side and the anti-drop bar fixing portion 10b on the other side have a symmetrical shape as shown in FIGS. 2(a) and 2(b).

Next, the operation of the fall prevention bar fixing device 10 having the above configuration will be described. The fall prevention bar fixture 10 can be used for both the medium weight rack 2 and the light weight rack 3. The width of the medium-weight rack 2 is set at, for example, 1555 mm, and the width of the lightweight rack 3 is set at, for example, 1500 mm.

The medium weight rack 2 is often set to be 55 mm larger than the light weight rack 3 . In such racks of different sizes, it is possible to use the fall prevention bar portion 8 and the fall prevention bar fixing portion 10a on one side and the fall prevention bar fixing portion 10b on the other side, which have the same length.
