Description

DETAILED DESCRIPTION

1. Technical Background

It is known, or at least intuitive, how in environments intended for storing explosives, ammunitions, arms and the like, the operations for moving, collecting and depositing the material as well as other operations, are quite sensitive, due to the risks related to the characteristics of the material itself.

In such context, for obvious safety reasons, all auxiliary movement devices that might generate sparks must be avoided completely thus substantially leading to such operations being performed manually.

2. Objects of the Invention

In such context, the main object of the present invention is that of providing means for facilitating the movement of the material in the rooms for storing, ammunitions, arms and the like, reducing the physical effort for the respective manual movement and without any contraindications in terms of safety.

Another object of the present invention is that of attaining the previous object through a solution concept applicable in any environment used for storing explosives, ammunitions, arms and the like, even not expressly prearranged and—as a matter of fact regardless of any prearrangement—being linked to the solution concept the adaptation of the same to the environment in question.

Other objects of the present invention are those of attaining the previous object and simultaneously providing a device suitable for:

not causing any contraindications in terms of safety and hygiene;

attaining the highest application modularity and polyvalence possible, as well as easy adaptability to the existing structures;

allowing immediate implementation without entirely altering the structures it is intended to complete,

attaining a solution concept feasibly useable even in other applications with respect to that of storing explosives, ammunitions, arms and the like, for which it was expressly conceived.

In any case obtain a simple and efficient device, safe to operate and least expensive possible considering the results practically attained therewith.

SUMMARY OF THE SOLUTION CONCEPT

These and other objects are attained by the floating floor structure according to the invention, comprising bearing pillars (1) with revolving ball (3) constrained in the head (2), projecting on the floor surface (10), supported by a grid of crosspieces (7) suspended between the bearing pillars (1) and made of material suitable to prevent the generation of sparks under friction or impact and prevent the accumulation of electrostatic energy, the entirety being used for building floors particularly for rooms intended for storing explosives, ammunitions, arms and the like, in such a manner that the pallets of the respective support may be easily translated and moved manually on the floating floor rolling on the heads of the pillars in a safe manner.
