It consists of an operating mechanism 3 that moves the vertical rod 2 up and down.

The fall prevention fitting 1 shown in FIG. 1 is a rod-shaped body bent at the middle, and one end is loosely fitted into the fixing hole of the protective box holder 13', and the other end is inserted into the other protective box holder 13'. It is loosely fitted into the elongated hole 11 so as to be able to swing vertically, and is biased upward by a spring member 12. When the swingable end portion 1a moves upward, the intermediate bent portion 1b or the end portion 1a of the fall prevention fitting 1 blocks the entrance and exit path of the protective box A, thereby preventing it from falling off. Normally, the protective box A is biased by a spring to this position to prevent it from falling off. Fall prevention bracket 1 (not shown)
All you have to do is push down the path blocking portions 1a or 1b. Note that this fall prevention fitting 1 is not necessarily bent in the middle, and the swingable end of the fall prevention fitting 1 is not limited to the protective box holder, but is also provided on a side column or part of a storage shelf. A long hole is also acceptable.

FIG. 2 is a detailed perspective view of another example of the fall prevention fitting, in which the bending of the intermediate portion 1b is step-like, and the swingable end portion 1a is perforated in the protective box holder 13. It is loosely fitted into the elongated hole 14. Spring member 12
is fixed at one end to the protective box holder 13, and at the other end to the end 1a of the fall prevention fitting to urge the end 1a upward.

The vertical rod 2 is provided with vertically elongated elongated holes 21 corresponding to the fall prevention fittings 1 of each stage, and the swingable end 1a of the fall prevention fitting 1 is communicated with the elongated holes 21. is moved upward, the elongated hole 21
The lower end of is related to the end 1a of the fall prevention fitting 1,
The end portion 1a is pressed against the upper end of the elongated hole 11 of the protective box holder 13, and the fall prevention fitting 1 is locked in the protective box fall prevention position. Therefore, when the vertical rod 2 is moved upward, even if a person enters the safe deposit box during maintenance or inspection, the vertical rod will be locked unless the operating mechanism, that is, the all-lock device that locks the vertical rod 2, is unlocked. 2 cannot be lowered, and the protective box A cannot be taken out; in other words, it is locked, and all storage shelves communicating with the vertical rod are locked.

In the above embodiment, the locking part that locks one swingable end of the fall prevention fitting is a long hole 2 drilled in the vertical rod.
1, but the locking part does not necessarily have to be a long hole, and can have a notch shape 21' as shown in FIG. 3A.
However, the protrusion shape 21'' as shown in FIG. 3B may also be used.

The actuating mechanism 3 can be of any shape and type as long as it moves the vertical rod 2 up and down, but the following mechanism is used in this embodiment.
