1. Safety apparatus (10, 20) for the movement of a plurality of pneumatically interconnected gas bottles (B, B′) under pressure, comprising:
the plurality of pneumatically interconnected gas bottles,
an internal support structure (11, 21), comprising a plurality of horizontal plates (P1, P21; P2, P3, P4), superimposed vertically, respectively at different levels with respect to the ground, and stably connected to each other,
wherein a support structure (11, 21) supports said plurality of bottles (B, B′), which contain a pressurised gas and are arranged in juxtaposition to each other on vertical axes, or on horizontal axes,
wherein each bottle (B, B′) in said plurality of bottles comprises respective pneumatic valve means (V) to intercept the flow of gas,
wherein a first plate (P1, P21), lower and close to the ground, is configured as a support pallet for said plurality of bottles (B, B′) and is raised above the ground by means of support feet (P11, P211),
wherein said pneumatic valve means (V) of each bottle (B, B′) in said plurality of bottles are pneumatically connected by means of a sealed pneumatic circuit (C) of the safety apparatus for connecting the pneumatic valve means (V) of all the bottles (B, B′), to each other and to a pneumatic connector (R) of the safety apparatus provided for removable connection of a flexible hose, which creates the pneumatic and mechanical connection with respect to an external appliance for using the gas, or respectively for carrying out filling with gas, of the bottles in said plurality of bottles (B; B′);
wherein said pneumatic connector (R) of said pneumatic circuit (C) is arranged at a higher level than that of said first plate (P1, P21),
wherein at least said first plate (P1, P21) forms with at least one pair of said support feet (P11, P211) and with the ground at least a slot, having a height sufficient to allow passage of the forks of a fork lift truck for movement of the apparatus (10, 20);
an external cage structure (12, 22), including a plurality of vertical uprights (12.11, 22.11), arranged around said horizontal plates (P1, P21; P2, P3, P4) of said support structure (11, 21) and rigidly connected with respect to said support structure (11, 21);
characterised in that said apparatus (10, 20) comprises;
a vertical interspace (I, I′), provided between said internal support structure (11, 21) and said external cage structure (12, 22);
screening means (13, 23), vertically mobile within said interspace (I, I′) and configured as a blind, that:
in a first lowered working position, closes said at least one slot between said first plate (P1, P21), said at least a pair of support feet (P11, P211) and the ground, while it does not screen from the outside said connector (R) of said pneumatic connection circuit (C) and it is possible for an operator to make the removable connection between said pneumatic connector (R) and said hose, and
in a second raised working position, screens from the outside said pneumatic connector (R) of said pneumatic connection circuit (C) and prevents an operator from making the removable connection between said pneumatic connector (R) and said hose, while it does not close said at least one slot and it is possible to move the apparatus (10, 20) using a fork lift truck, the forks of which are insertable through said at least one slot,
and transfer command means (14, 24), configured to selectively control the vertical movement of a mobile screening means (13, 23), respectively into said first lowered working position and into said second raised working position.
